Abstract
The invention discloses a squeezing method for a press filter. The squeezing method includes the following steps: firstly, materials to be filtered enter a filter chamber for filtration through a feed inlet of an elastic body frame; secondly, filter plates are used for compressing the elastic body frame for the filtration, and the elastic body frame is compressed by five millimeters in the filtration stage to guarantee that certain pressure is formed on a contact face between the elastic body frame and the filter plates and filtrate cannot leak out; thirdly, after the filtration, due to the fact that a large amount of liquid is still stored in a filter cake, squeezing must be carried out to squeeze out remaining liquid, and when the two filter plates compress the elastic body frame to 20 millimeters, the feed inlet is closed completely; and finally, the squeezing is continued till the liquid in the filter chamber stops flowing out. According to the squeezing method for the press filter, the materials are subjected to pressure filtration first and then are squeezed in the pressure filtration process, the feed inlet is pressed to be closed completely, the humidity of the filter cake is greatly improved, and smooth feeding next time is guaranteed.
Description
Technical field
The present invention relates to filter press.
Background technology
Filter press is a kind of intermittent solid-liquid separating equipment, carries out the Separation of Solid and Liquid operation.Existing filter press (sheet frame, van-type, diaphragm pressing) is cake layer work principle of filter (and flowing through filter).It arranges charging aperture at filter plate usually, passes through the valve closing charging aperture in the pressure-filtering process.Filter opening in the pressure-filtering process on the filter plate stops up easily, and the charging aperture shutoff operation is loaded down with trivial details.
Summary of the invention
Technical problem to be solved by this invention just provides a kind of filter press pressing method, and charging aperture can autoshutdown, and the filter opening on the filter plate is not easy to stop up.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of filter press pressing method, it is characterized in that: filter press is comprised of the squeeze frame of several stacked settings, described squeeze frame comprises two parallel filter plates, be provided with the elastomer frame between two filter plates, sealing is fitted between described elastomer frame and the filter plate, elastomer frame and two filter plates surround filter chamber, described elastomer frame is provided with the charging aperture that is communicated with filter chamber, described charging aperture is strip, and charging aperture is long to be 40mm, and wide is 20mm, two ends are the circular arc of R10mm, and the filter press filter-pressing method comprises the steps:
At first, the material that need to filter enters filter chamber by the charging aperture of elastomer frame and filters;
Secondly, filter plate compresses elastomeric frame filters, and at the compressed 5 millimeters contact-making surfaces with assurance elastomer frame and filter plate of this filtration stage elastomer frame certain pressure is arranged, and guarantees that filtered fluid can not leak;
Then, squeeze, filter and finish rear because the filter cake of this moment also has a large amount of liquid, thus must squeeze, the liquid of the surplus of squeezing out, when two filter plates were pressed to 20 millimeters, charging aperture was fully closed; At last, continue squeezing, stop until the liquid phase in the filter chamber flows out.
As preferably, described elastomer frame outer rim is provided with a circle flange, is provided with the gap between described flange and two filter plates.
As preferably, described elastomer frame is provided with the iron circle around flange and wales the elastomer frame.
As preferably, be provided with the chamfered transition structure between described flange root and the described elastomer frame.
As preferably, described filter press is plate and frame filter press or chamber-type press filter.
The present invention surrounds filter chamber by elastomer frame and filter plate, establishes charging aperture in resilient bezel, and material is first through press filtration in the pressure-filtering process like this, and then again squeezing is so that charging aperture pressurized and complete closed improves the filter cake humidity greatly guarantees again the unimpeded of next time charging.In filtration, guaranteed not revealing of filtrate.In the filtration of rear further squeezing, the mud humidity greatly improves again, and is simple in structure, guaranteed the unimpeded of charging, and charging aperture can autoshutdown in pressure-filtering process, and the filter opening on the filter plate also is not easy to stop up.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of squeeze frame discharging opening position;
Fig. 2 is the structural representation of the non-discharging opening of squeeze frame position.
