In recent years, environmental protection and resource problems have been the focus of people's attention. People not only advocate in life, all walks of life also requires environmental protection. In the pharmaceutical industry, the concept of environmental protection is inseparable from the sewage treatment link. How to treat sewage more environmentally? This is of course inseparable from the application of filter press. With the continuous improvement of filtration and separation technology requirements, the filter press industry is also developing forward. Due to the advantages of simple operation and strong practicability, the plate and frame filter press has become a new favorite in the filter press industry.

Use of plate and frame filter press

Filter press as a solid-liquid separation equipment, has a long history of application in industrial production, it has a good separation effect, wide adaptability, especially for the separation of viscose fine materials, has its unique advantages.

The plate-frame filter press is a very mature dewatering equipment, which is widely used in the early dewatering projects of sludge in Europe and America. Plate and frame filter press is a kind of equipment for separating solid and liquid in industrial production, which is used in chemical industry, ceramics, petroleum, medicine, food, smelting and other industries. Easy operation and maintenance, safe and reliable operation.

Plate and frame filter press is by compression part, thrust plate, pressure plate, bar, composed of a frame, all filter plate and filter box composite frame alternately in two equal support beams, all corresponding parts of the filter plate and filter box has a fluid channel, used to introduce suspension liquid or liquid discharge, all on both sides of the filter plate and filter frame between the sealing surface of the same shape, filter cloth clamp between the plate and frame sealing surface, become a sealing gasket within a filter plate and frame seal face, support the filter cloth filter surface is full of groove, groove and all discharge filtrate channel are interlinked, a filter machine composed of many parallel filter chamber, Both sides of each filter chamber are provided with a filter cloth layer that prevents the solid particles in the suspension from passing through and allows the filtrate to permeate. The total filtration area of these filter plates represents all the production capacity of the filter press.

The present situation of plate and frame filter press industry in China

China's filter press machinery manufacturing industry is still a developing industry. The author is informed, in very long period of time, the plate-frame filter press of our country can rely on foreign imports only, the enterprise that domestic can produce this kind of equipment is not much still. The equipment is in great demand in chemical, petrochemical, food, pharmaceutical, military manufacturing and other fields. In terms of inlet, China's inlet pressure filter machinery, due to low content, poor reliability, very few inlet. It was only in the past two years that this began to change. It is reported that China's production of diaphragm filter has begun to import to the United States, Europe and Japan and some other developed countries, but on the whole, China's separation pressure filter machinery technology level and foreign advanced technology level compared to the larger difference, but this will also be China's filter press industry potential market.

The expert has carried on the thorough summary to the present stage development, thought that at present, our country's plate frame filter press profession development also has the following aspects weakness.

1. Low level of management and enterprise informatization.

China's filter press industry started early, one part of the enterprise is from the workshop type of production evolved, the enterprise boss lack of long-term vision, do not know how to manage, often in the cost accounting, quality control, market broaden greatly discount. In addition, now is the information society, if not grasp the market information or low degree of information, will affect the rapid development of enterprises.

2. Low degree of specialization, standardization and commercialization, poor sense of collaboration.

Filter press manufacturer in China basically is private enterprise, the specialized division of labor is not fine, low degree of production socialization, the collaboration between enterprises is not enough, greatly reduce the potential of the industry and enterprise development, and such due to a surplus of products in the market, companies tend to rely on price competition to survive, for the market, the direct impact on the development of filter press industry environment.

3, the implementation of technology and equipment, the lack of enterprise development momentum.

At present, most of China's filter press enterprises mainly rely on foreign technical equipment, production equipment can not be updated in a timely manner, seriously hindered the development of enterprises. Without new production equipment, the level of process equipment can not be improved, can not produce high-tech products, can not meet the market demand. Without continuous development of new products, an enterprise will have no development momentum and will be difficult to become bigger and stronger.

The development trend of plate filter press industry

With the introduction of the most stringent environmental protection law, the 13th five-year plan and the tenth water and soil law and other policies, the market demand for plate and frame filter press in the next few years can be said to be considerable, which will also lead to more fierce market competition. In order to stand out in the competition, brand management is an important link, but it is undeniable that its investment cost is also high, the plate and frame filter press enterprises should strengthen technological breakthrough, the introduction of foreign advanced technology and equipment, strengthen the application of plate and frame filter press, promote the development of domestic filter press industry.

"Twelfth five-year" period, China's production of filter press industry growing, according to the China general machinery industry association separation machinery branch of statistics show that from 2012 to 2014, the domestic press filter industry sales size is about 4.2 billion yuan, 4.55 billion yuan, 4.7 billion yuan, an average annual growth rate of 5.82%, industry scale increased year by year, filter press in our country has formed a certain market scale.

During the "13th five-year plan", China advocates that on the basis of the domestic market, some powerful enterprises should actively explore going out, carry out international business, and expand the international market. Driven by market demand and national policies, the market prospect of filter press industry is very promising.

Industry thinks, filter press industry during the period of "much starker choices-and graver consequences-in" development, should also make the Internet a plan of action, to promote mobile Internet, cloud computing, big data, such as the Internet of things combined with pressure filter manufacturing, promote the electronic commerce, industrial development of the Internet and Internet financial health, guide the Internet companies to expand the international market.

Throughout the development trend of filter press industry, China's plate and frame filter press industry should pay close attention to the demand of environmental protection field during the 13th five-year plan period, accelerate the adjustment of product structure, turn the weakness of development into competitive advantage, and technology as the core, improve the overall level of the industry, and lay a good foundation for future export development. It is reported that the SHBY type stainless steel plate and frame filter press manufactured by ningbo huazi pharmaceutical equipment manufacturing co., ltd. follows the development trend closely and stands out in the market. The machine is mainly used in Chinese and western pharmaceutical, biological pharmaceutical, veterinary medicine, food, beverage and other industries. Compared with the ordinary filter press, this product has wider filter frame, which greatly increases the volume of filtration. It is not only suitable for the clarification and filtration of raw material liquid, but also suitable for the filtration of raw material slag and the filtration of material liquid with higher viscosity, so as to better meet the high standard requirements of pharmaceutical enterprises.
