[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0029] Therefore, the following detailed description of the embodiments of the present utility model is not intended to limit the scope of the present utility model to be protected, but merely represents some embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0030] It should be noted that, without conflict, the embodiments and the features and technical solutions in the embodiments of the present utility model can be combined with each other.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0032] As Figures 1-5 shown, this embodiment provides a discharge mechanism for a filter press, including a discharge chute body 1. A cleaning mechanism 2 for preventing materials from sticking to the inner wall of the discharge chute body 1 is arranged inside the discharge chute body 1, and a filtering component 3 is arranged inside the cleaning mechanism 2.

[0033] The cleaning mechanism 2 includes a liquid inlet tank 201, a connecting tank 202, a liquid discharge tank 203, a connecting pipe 204 and a water inlet pipe 205. The liquid inlet tank 201 is opened in the wall of the discharge chute body 1. The connecting tank 202 is opened at the bottom of the liquid inlet tank 201. The liquid discharge tank 203 is opened at one end of the connecting tank 202. The connecting pipe 204 is bolted to the top of the discharge chute body 1. The water inlet pipe 205 is connected and arranged on the outer wall of the connecting pipe 204. The number of the connecting tanks 202 is several and they are evenly distributed. One end of the connecting tank 202 is communicated with the inside of the liquid inlet tank 201. When there are more products to be filtered, filter cakes will be generated, making it difficult to clean. By injecting water into the inside of the water inlet pipe 205, the filter cakes can be conveniently washed down.

[0034] As Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, the filtering component 3 includes an installation pipe 301 and a filter screen 302. The installation pipe 301 is threadedly connected to the top of the water inlet pipe 205. The filter screen 302 is bonded to the inside of the installation pipe 301. The filter screen 302 is made of stainless steel. When injecting water into the inside of the discharge chute body 1, the filter screen 302 can filter the water. At the same time, one end of the installation pipe 301 is threadedly connected to the water inlet pipe 205, so the filter screen 302 can be conveniently replaced, playing a role in facilitating the replacement of the filter screen 302.

[0035] As Figure 5 shown, as a preferred embodiment, on the basis of the above method, further, a vertical pipe 4 is threadedly connected to the top of the installation pipe 301. A flange 5 for facilitating the installation of the vertical pipe 4 is welded on the outer wall of the top end of the vertical pipe 4. When in use, the vertical pipe 4 can be conveniently connected to the external water inlet pipe through the flange 5.

[0036] As Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, a guide ring 6 for preventing silt from accumulating on the top of the installation pipe 301 is welded on the top of the installation pipe 301. The side wall of the guide ring 6 is closely attached to the inner wall of the vertical pipe 4. The cross-sectional shape of the guide ring 6 is a right triangle. When injecting water, the guide ring 6 can prevent silt from accumulating on the top of the installation pipe 301, improving the cleanliness.

[0037] As Figure 3 shown, as a preferred embodiment, on the basis of the above method, further, a check valve 7 for preventing liquid backflow is bolted inside the connecting groove 202. The number of check valves 7 is the same as that of the connecting grooves 202. When pressing the filter product, the check valve 7 can prevent the pressed-out liquid from flowing back.

[0038] As Figure 1 shown, as a preferred embodiment, on the basis of the above method, further, an anti-wear plate 8 for reducing the friction between the material and the discharge chute body 1 is welded on the inner wall of the discharge chute body 1. The anti-wear plate 8 is made of 316L stainless steel. One end of the liquid discharge groove 203 penetrates through the anti-wear plate 8. During pressure filtration, the anti-wear plate 8 can prevent the friction between the filter cake and the discharge chute body 1 from being too large, resulting in difficulty in removing the filter plate.

[0039] As Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, a sealing gasket 9 is bonded to the top of the installation pipe 301. The bottom of the vertical pipe 4 is in close contact with the top of the sealing gasket 9. When injecting water into the vertical pipe 4, the sealing gasket 9 can improve the sealing performance between the installation pipe 301 and the water inlet pipe 205.

[0040] Specifically, after the discharge mechanism of this filter press finishes pressing the product inside the discharge chute body 1, when the material is less, solid particles gradually accumulate on the inner wall of the discharge chute body 1 to form a filter cake. Then the user collects the liquid. After the filter cake is generated, the anti-wear plate 8 can make the wall surface smoother, thereby reducing the friction force, and it can be freely unloaded when the material is not much. When the material is too much, the filter cake will stick to the inner wall of the discharge chute body 1, resulting in difficulty in cleaning. At this time, the user connects and fixes the external water inlet pipe 205 to the vertical pipe 4 through the flange 5. Then the filter screen 302 can filter the water to prevent scale from blocking the water inlet pipe 205. Then the water sequentially enters the inside of the water inlet pipe 205, the communication pipe 204, the liquid inlet groove 201 and the connecting groove 202, and then is discharged through the liquid discharge groove 203, thereby flushing down the filter cake. When flushing down the filter cake, it will not cause the parts of the equipment to become loose due to the vibration of the equipment, which will affect the service life of the equipment.

[0041] All technical features in this embodiment can be freely combined according to actual needs.

[0042] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
