Further, the filter cloth 2 outside the plate body 1 in the prior art is fixed, the filter cloth 2 is fixed on the groove based on the groove arranged outside the plate body 1, the filter cloth 2 is compressed by a cloth pressing strip 31 for compressing the filter cloth 2, and bolts are fixed on the cloth pressing strip 31; the fixing mode is not completely fixed, because the fixing force is concentrated on the bolts, water leakage or loosening of the filter cloth 2 is easy to occur, and the filter cloth 2 is deformed due to repeated impact in the filter pressing process when the local stress is large.
The design is provided with a locking device 3; the cloth pressing strips 31 are arranged in the cloth pressing grooves 12, the cloth pressing strips 31 are fixed on the locking device 3, and the tightening degree of the cloth pressing strips 31 is controlled by the locking device 3, so that when the filter cloth 2 needs to be untied, the locking device 3 is loosened, and the encircling and tightened cloth pressing strips 31 are loosened; when the filter cloth 2 is required to be fixed, the tightness adjusting component 32 is only required to be connected with the cloth pressing strip 31, the cloth pressing strip 31 is tensioned and locked by the tightness adjusting component 32, so that the cloth pressing strip 31 is in a tensioned state, the whole cloth pressing strip 31 applies pressure to the center of the plate body 1 and the filter cloth 2 of the cloth pressing groove 12 in a ring shape, the center of the plate body 1 is provided with the center fixing piece 4 for fixing the center of the filter cloth 2, the center fixing piece 4 is tightly pressed at the center of the plate body 1, the filter cloth 2 basically does not fall off under the structural state, the effect of improving the fixing effect of the filter cloth 2 on the plate body 1 is achieved, the water leakage condition is reduced, and the problems of loose fixing of the filter cloth 2 and water leakage in the prior art are solved;
compared with the prior art, the filter cloth 2 is uniformly stressed due to the fact that the cloth pressing strips 31 annularly press the filter cloth 2, so that the filter cloth 2 is not deformed.
Meanwhile, the main loss product in the design is the cloth pressing strip 31, and only the cloth pressing strip 31 needs to be replaced during replacement, and other elements do not need to be replaced, so that the daily maintenance times of the design can be reduced only by selecting materials with strong toughness.
Further illustratively, the slack adjuster assembly 32 includes: a locker 321 and a slack adjuster 322; the number of the lockers 321 is at least 2, and the lockers 321 are respectively arranged at the end parts of the cloth pressing strips 31;
the locker 321 is horizontally provided with a locking hole;
the tightness adjusting members 322 pass through the locking holes of the respective lockers 321, so that the lockers 321 can be locked at intervals by the tightness adjusting members 322.
Further, in the design, the lockers 321 are respectively connected with the cloth pressing strips 31, the lockers 321 are parallel to each other, the pressing force of the cloth pressing strips 31 can be increased only by adjusting the interval between the lockers 321, and the cloth pressing strips 31 have the maximum pressing force on the filter cloth 2 until the tightness adjusting piece 322 can not be adjusted to be close to the distance between the lockers 321, so that the lockers 321 of the design provide the function of adjustable pressing force; the method is particularly applied to different occasions, for example, when pre-press filtration is carried out, the press filtration efficiency requirement is relatively low, the proper adjustment of the pressing force is moderate and small, the service life of the cloth pressing strip 31 is prolonged, and the installation and the disassembly are convenient; and when normal filter pressing is carried out, the selected pressing force is larger, so that the fixing effect and the filter pressing efficiency of the filter cloth 2 are improved.
