Abstract
The invention discloses a feed inlet structure of a squeezing frame of a press filter. The feed inlet structure of the squeezing frame of the press filter comprises an elastic body frame, the elastic body frame is provided with a feed inlet which is in a long strip shape, the feed inlet is 40mm long and 20mm wide, each of two ends of the feed inlet is provided with a circular arc with a 10mm radius, the outer edge of the elastic body frame is provided with a flange in a circle shape, and the flange surrounding the elastic body frame is provided with an iron hoop which is used for clamping the elastic body frame. According to the feed inlet structure of the squeezing frame of the press filter, the elastic body frame and filter plates are enclosed to form a filter chamber, the feed inlet is arranged in the elastic body frame, and therefore 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 a filter cake is greatly improved, and smooth feeding next time is guaranteed. During the filtration, non-leakage of filtrate is guaranteed. In the squeezing process during the filtration, the humidity of sludge cakes is greatly improved. The feed inlet structure of the squeezing frame of the press filter is simple in structure, and guarantees smooth feeding. Moreover, the feed inlet can be closed automatically during the pressure filtration, and filter holes in the filter plates are not prone to blockage.
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 squeeze frame feeding inlet structure, and is simple in structure, and charging aperture can autoshutdown, also makes the filter opening on the filter plate be 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 squeeze frame feeding inlet structure, comprise the elastomer frame, it is characterized in that: described elastomer frame is provided with charging aperture, described charging aperture is strip, charging aperture is long to be 40mm, and wide is 20mm, and two ends are the circular arc of R10mm.
As preferably, described elastomer frame outer rim is provided with a circle flange.
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, at non-charging aperture position, described iron circle medial extremity is provided with draw-in groove, and described flange is connected to location in the draw-in groove.
As preferably, at the charging aperture position, the described flange left and right sides is provided with groove, and described iron circle hoop is located in the described groove.
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.
The specific embodiment
See figures.1.and.2 the embodiment of filter press squeeze frame feeding inlet structure of the present invention is described, filter press forms by several squeeze frames are stacked, described squeeze frame comprises two parallel filter plates 1, be provided with elastomer frame 2 between two filter plates 1, sealing is fitted between described elastomer frame 2 and the filter plate 1, elastomer frame 2 and two filter plates 1 surround filter chamber 4, and described elastomer frame 2 is provided with the charging aperture 5 that is communicated with filter chamber 4.
Described charging aperture 5 is strip, and charging aperture is wide to be 20mm, and long is 40mm, and two ends are the circular arc of R10mm.Described elastomer frame 2 outer rims are provided with a circle flange 6, are provided with gap 8 between described flange 6 and two filter plates 1.Certain space has been reserved to filter plate 1 compresses elastomeric frame 2 in this gap.
Described elastomer frame 2 is provided with iron circle 3 around flange 6 and wales elastomer frame 2.At non-charging aperture position, described iron circle 3 medial extremitys are provided with draw-in groove, and described flange 6 is connected to location in the draw-in groove.At the charging aperture position, described flange 6 left and right sides are provided with groove, and described iron circle 3 hoops are located in the described groove.Be provided with chamfered transition structure 7 between described flange 6 roots and the described elastomer frame 2.Described filter press is plate and frame filter press or chamber-type press filter.
The filter-pressing method of above-mentioned filter press 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.
