The thrust part 200 is fixedly disposed at the front end of the bracket 100, and specifically, the thrust part 200 is welded and fixed to the two support beams 110 of the bracket 100 and is located between the two support beams 110. The thrust part 200 is provided with a feeding hole, a communication hole and other interfaces, so that the filter assembly 500 is conveniently compressed to the main thrust part and then raw materials to be filtered are provided into the filter assembly 500. The power device 400 is fixedly arranged at the rear end of the bracket 100, and the power device 400 is welded on the bracket 100. The compressing part 300 is driven by a power unit 400 to approach or separate from the thrust part 200, and the compressing part 300 is movably disposed between the support beams 110 in the front-rear direction. The plurality of filter assemblies 500 are arranged between the thrust part 200 and the compressing part 300, and the plurality of filter assemblies 500 are pushed by the compressing part 300 to be pressed onto the thrust part 200 and connected with the thrust part 200 to form a filter passage, thereby realizing a normal filter-pressing function. The plate and frame filter press further comprises a one-way pushing mechanism 600, wherein the one-way pushing mechanism 600 comprises a telescopic part 610 and a pushing part 620. The extension part 610 is provided to the bracket 100 to extend and contract in the moving direction of the pressing part 300, and the pushing part 620 is connected to the extension part 610. The push portion 620 moves up against the filter assembly 500 by the expansion of the telescopic portion 610, or the push portion 620 moves down to be separated from the filter assembly 500 by the contraction of the telescopic portion 610.

When the compressing part 300 moves towards the filter assembly 500, the telescopic part 610 is shortened, and the pushing part 620 moves downwards to be separated from the filter assembly 500 through the shortening of the telescopic part 610, so that the compressing part 300 pushes and compresses the filter assembly 500, and the filter pressing process is not influenced.

As shown in fig. 1 and fig. 3, in the specific structure of this embodiment, two unidirectional thrust mechanisms 600 are provided, and the two unidirectional thrust mechanisms 600 are arranged on the left and right sides of the bracket 100 in a mirror image manner. This allows filter assembly 500 to be pushed from both the left and right sides simultaneously, allowing filter assembly 500 to slide stably on support beam 110. Since the left and right sides have the same structure, the left side will be described as an example. As shown in fig. 1 and 2, a first guide groove 120 extending along the moving direction of the pressing portion 300 is formed on the left side surface of the bracket 100, and the first guide groove 120 is disposed along the front-back direction.

The pushing portion 620 includes a pushing plate 622, the pushing plate 622 is movably disposed in the through slot, and the pushing plate 622 is hinged to the hinge frame 613. When the two movable columns 612 approach each other, the first hinge plate 614 and the second hinge plate 615 approach each other, so that when the hinge joint of the first hinge plate 614 and the second hinge plate 615 drives the pushing part 620 to move, the pushing part 622 can be kept in a vertical direction due to the through slot on the guide block 621. This facilitates pushing the filter assembly 500.

The clearance chamfer 623 can reduce the interference probability of the filter assembly 500 on the pushing plate 622, so that the pushing plate 622 can stably move up and down.

As shown in fig. 2 and 4, the one-way pushing mechanism 600 further includes a power connection portion 630, one end of the power connection portion 630 is hinged to the movable column 612 facing the pressing portion 300, and the other end is hinged to the pressing portion 300. The power of the pressing part 300 moving away from the filter assembly 500 can be converted into the power of the movement of the one-way push mechanism 600 through the power connection part 630. It is easy to conceive that the power of the one-way thrust mechanism 600 may be additionally provided.

As shown in fig. 2 and 4, in the specific structure of the present embodiment, the power connection portion 630 includes: a first powered hinge plate 631 and a second powered hinge plate 632. One end of the first power hinge plate 631 is hinged to the movable post 612 facing the pressing part 300.

The pushing portion 620 is located between two adjacent support plates 520. When the expansion part 610 is expanded, the pushing part 620 is pulled to move upwards, so that the pushing part 620 can abut against the supporting plate 520, the expansion part 610 is continuously expanded, the pushing part 620 can be pulled to move backwards, and thus the filtering frame 510 can be driven to move backwards, so that the filtering assemblies 500 are separated.

As shown in fig. 4, the pressing part 300 includes: moving plate 310, support column 320, and roller 330. The moving plate 310 is close to or far from the thrust portion 200, the supporting pillars 320 are fixedly connected to two sides of the moving plate 310 and located above the support 100, and the rollers 330 are rotatably connected to the supporting pillars 320 and located on the upper surface of the support 100 to slide. The second powered hinge plate 632 is hinged to the support post 320. The roller 330 facilitates the pressing part 300 to reduce the friction force with the bracket 100 when being pushed, and is more convenient to move. When moving, the supporting column 320 pushes the second power hinge plate 632, the second power hinge plate 632 drives the first power hinge plate 631, and the first power hinge plate 631 drives the movable column 612 and the hinge frame 613, so that power transmission is realized.

In summary, in the plate and frame filter press according to the present invention, the unidirectional moving mechanism 600 is disposed on the bracket 100, so that the filter assembly 500 still pressed together after the filter pressing process is completed can be separated, and the unidirectional moving mechanism 600 includes the telescopic portion 610 and the moving portion 620. The extension of pusher jack 620 through pars contractilis 610 and upwards shift up and support and lean on filtering component 500, after pusher jack 620 shifts up and supports and lean on filtering component 500, pars contractilis 610 continues the extension, and pars contractilis 620 removes along the extension direction like this to the filtering component 500 that will compress tightly separates, and filtering component 500 after the separation more makes things convenient for single hoist and mount to dismantle, does benefit to like this and unloads the sediment after unloading filtering component 500 one by one, improves filtration efficiency. When the compressing part 300 moves towards the filter assembly 500, the telescopic part 610 is shortened, and the pushing part 620 moves downwards to be separated from the filter assembly 500 through the shortening of the telescopic part 610, so that the compressing part 300 pushes and compresses the filter assembly 500, and the filter pressing process is not influenced.
