Description
Technical Field
The utility model relates to a, more specifically relates to a filter cloth for filter press convenient to dismouting.
Background
The filter is the equipment that utilizes filter medium and exert certain pressure thereby realize solid-liquid separation, has very long development history, has had the application of the most original pressure filter in public yuan one hundred years 'chinese court Liu' an utility model bean curd. Intermittent plate-and-frame filter presses were known in the 19 th century, but the use of the filter press was limited because the press had to be unloaded manually. With the development demand of society and the progress of technology, automatic type filter pressing was developed in 1958, and then the filter pressing machine has made a great progress and is widely applied to various concentrating mills. Filter presses are classified into intermittent and continuous filter presses according to the continuous nature of operation, and continuous filter presses, such as belt filter presses, operate with both discharge and feed being performed simultaneously. However, since the continuous type filter press generally has a relatively complicated structure, the batch type filter press is more commonly used. The discharge and feeding of the intermittent filter press are carried out periodically and generally comprise five steps of slurry feeding and cake forming, filter cake washing, squeezing and dewatering, discharging and filter cloth cleaning.
The following are several common filter presses:
plate and frame filters are the earliest and most widely used filtration equipment. The plate-and-frame filter press has a simple structure, and a filter chamber is formed by pressing a plurality of filter frames and filter plates together. At present, plate-and-frame filter presses are widely used in the industries of mines, pharmacy, chemical industry, metallurgy, dyes, environmental protection, ceramics and the like.
The development of chamber filters, the filter chamber of which is composed of two filter plate depressions, began in the 60's of the 20 th century. It features high filtering pressure up to 2 MPa; the single machine has large filtering area, the prior foreign box type filter press 1727m2 is available, and the domestic maximum filtering area reaches 1050m 2.
The quick-opening filter press is a filter press developed on the basis of a common filter press, and is mainly different from the common filter press in that a pull plate is in a form of pulling a plurality of blocks, and the compression return stroke wastes time because the pull plate is pulled one by one. The APN plate and frame filter press of Cuminks is a typical quick-open filter press. The APN plate-frame filter press comprises a blowing system, a diaphragm pump, a plate frame, filter cloth, a plate frame opening and closing device, a control system, a hydraulic system and the like. The quick-opening filter press is not provided with a forced cake discharging device and a cloth washing device, so once the water content of the filter cake is too high, the filter cake cannot be discharged by self weight and a worker needs to poke the filter cake down. And if the filter cake is not thoroughly removed, ore is easily clamped at the sealing surface of the plate frame to cause the guniting and air leakage of the filter plate, and meanwhile, the filter cloth is quickly damaged and is frequently replaced, and great noise is also generated during air leakage.
The Larox type automatic filter press comprises two types, namely Larox-CF (horizontal type) and Larox-PF (vertical type), and is a novel filter press developed and produced by Finland Raox. The Larox-PF type automatic filter press is a full-automatic filter press of squeezing type, vertical type, filter cloth full-walking type. The working process of the filter press comprises four processes of filter pressing, squeezing, drying and cake unloading. (1) And (3) filter pressing: after the filter plates are closed, the suspension is pumped into the filter press by a slurry pump and enters each filter chamber of the filter press, a solid phase is intercepted by the filter cloth to form a filter cake, and a liquid phase is discharged out of the filter press through the filter cake and the filter cloth. (2) Squeezing: after the filter cake is formed, the pressure station starts to supply water, pressurized water enters the pressure water cavities of the filter pressing plate frames through the hoses respectively, and the filter cake is extruded through the rubber diaphragms, so that the water content of the filter cake is further reduced. (3) Drying: compressed air enters the filter chamber from the feeding pipe and permeates through the filter cakes to replace pore water among the filter cakes, the filter cakes are further dehydrated, and filtrate and air are discharged out of the filter press. (4) Unloading the cake: after the air drying is finished, the filter plate assemblies are sequentially opened, the filter cloth moving mechanism is started, and filter cakes on the filter cloth are discharged from the two sides of the filter press.
From the above analysis, the filtering mechanism of the filter press, i.e. the filter cloth and the peripheral structure of the filter cloth, play a crucial role in the filtering process, and how to design a filter cloth with more stability and higher filtering effect is a key issue in the continuous research, exploration and development in this field.
