[0003] The Chinese utility model patent with application number 202220992692.2 discloses a discharge device for a filter washing and drying machine. The left side of the filter washing and drying machine is connected to the vacuum discharge device through a discharge device, and the discharge is carried out by vacuum suction. However, since the discharge device is arranged on the left side wall of the filter washing and drying machine, there is still residual material in the filter washing and drying machine device after the discharge is completed and cannot be taken out. In view of the above situation, the method of the prior art is to open the side discharge valve, use the material rake tool to collect the remaining powder on the chassis to the discharge port, and push the three-in-one chassis into the loading container. The chassis of the three-in-one sintered mesh is a circular structure. Since the material rake tool is a rod-shaped structure, this material rake tool has some blind spots for cleaning and cannot collect all the remaining powder on the chassis. During the cleaning process of the material rake tool, there will be a lot of dust flying from the powdered material. Utility Model Content

[0026] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0027] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. The subsequent embodiments will not explain this one by one.

[0028] The directions and positions mentioned in the present invention, such as "upper", "lower", "front", "back", "left", "right", "inside", "outside", "top", "chassis", "side", etc., are only for reference to the directions or positions of the drawings. Therefore, the directions and positions used are used to explain and understand the present invention, but not to limit the scope of protection of the present invention.

[0029] In one embodiment of the utility model, a filtering washing and drying machine comprises a container 1, a filter screen 11 arranged above the bottom plate of the container, a discharge port 12, a discharge valve component 13 and a stirring mechanism 14;

[0030] The stirring mechanism 14 is located at the top of the filter-washer-dryer container 1, and the stirring mechanism 14 comprises a stirring power module 141, a stirring bracket 142, a mechanical seal 143, a stirring main shaft 144, a stirring paddle 145, a stirring paddle lifting cylinder 146 and a metal bellows 147;

[0031] The stirring power module 141 includes a stirring motor 1411 and is installed on a stirring bracket 142. The stirring bracket 142 is installed on the container 1. The stirring main shaft 144 and the stirring paddle 145 are connected to the stirring power module 141 and extend into the container 1. The stirring power module 141, the stirring bracket 142, the stirring main shaft 144, and the stirring paddle 145 can be raised or lowered along the main shaft direction by the stirring paddle lifting cylinder 146.

[0032] It is understandable that the stirring shaft 144 and the stirring paddle 145 are arranged in the container 1 along the Figure 1 The container 1 rotates in the direction of A and rises or falls along the main axis, so that the material in the container 1 can be pushed out from the discharge port 12.

[0033] The mechanical seal 143 is connected to the container 1 . The upper end of the mechanical seal 143 is connected to the stirring main shaft 144 and the lower end is connected to the stirring paddle 145 through a metal bellows 147 . The stirring main shaft passes through the mechanical seal and extends into the container 1 .

[0034] It can be understood that the metal bellows 147 can meet the changes in the axial direction of the main shaft during the rising or falling process, and can completely isolate the filter washing and drying machine from the external environment, prevent foreign matter from rubbing against and falling into the material, and ensure that the material in the filter washing and drying machine will not leak out during the rising or falling process of the stirring main shaft of the filter washing and drying machine, and the external environment will not contaminate the material in the filter washing and drying machine.

[0035] The discharge valve component 13 is installed on the side wall of the filter washing and drying machine container 1, and the discharge valve component 13 includes a discharge valve 131 and a discharge port 12. The lower edge of the discharge port 12 is flush with the surface of the filter screen 11, and the discharge valve 131 is used to control the opening and closing of the discharge port 12. It can be understood that when the discharge valve 131 is opened, the material can smoothly slide out of the discharge port 12 under the driving action of the stirring paddle; when the discharge valve 131 is opened and turned to one side, the discharge port 12 is exposed to the outside, and the material on the filter screen 11 on the bottom plate of the container 1 can be collected by other means.

[0036] The filter screen 11 is a circular flat plate structure. It can be understood that the filter screen 11 is used to separate solid-liquid mixed materials. The liquid material penetrates the filter screen 11 and is removed, and the solid material remains on the filter screen 11; the filter screen 11 is a circular flat plate structure to fit the shape of the container 1, so as to prevent the material from gathering in the gap between the filter screen 11 and the bottom plate of the container 1, which is not easy to collect. The shape of the filter screen 11 can be changed with the shape of the bottom plate of the container 1.

[0037] The filter washing and drying machine of the present embodiment is provided with a chassis residual powder collecting device with a vacuum suction function. The chassis residual powder collecting device is independent of the filter washing and drying machine and is a highly efficient auxiliary device for collecting residual powder on the chassis of the filter washing and drying machine. The residual powder collecting device 2 comprises a suction pipe 21, a vacuum port 22, a dust collecting barrel 24 and a filter barrel 25. One end of the suction pipe 21 extends into the container 1 and its port is located above the filter screen 11 above the chassis of the container 1, and the other end is connected to the dust collecting barrel 24. The dust collecting barrel 24 is provided with a vacuum port 22 for connecting to the vacuum device and a residual material inlet 241 connected to the suction pipe 21.

[0038] The filter cartridge 25 is disposed in the dust collecting cartridge 24 , separating the vacuum port 22 and the residual material inlet 241 .

[0039] It is understandable that the vacuum port 22 is opened to form a vacuum in the dust collecting barrel 24. During the vacuuming process, the residual powder of the filter screen 11 above the bottom plate of the container 1 enters the dust collecting barrel 24 through the suction pipe 21, and the filter barrel 25 is provided to separate the vacuum port 22 and the residual material inlet 241 to prevent the residual powder from being sucked away by the vacuum source.

[0040] The suction pipe 21 is a deformable structure, and the residual powder collecting device 2 includes a suction pipe driving device, which is connected to the suction pipe 21 to drive the mouth of the suction pipe 21 to move on the upper end of the chassis 11. It can be understood that the deformable structure allows the suction pipe 21 to change its shape, which facilitates the suction pipe 21 to move on the upper end of the chassis 11 to absorb the residual material, thereby avoiding a blind area for suction.

[0041] The pipe opening of the suction pipe 21 located above the bottom plate of the container 1 is a polytetrafluoroethylene suction head 211. It is understandable that the softer material property of polytetrafluoroethylene can prevent the surface of the filter screen 11 on the bottom plate of the container 1 from being damaged during the sliding process on the bottom plate of the container 1.

[0042] The suction pipe driving device is a holding rod 26 , which is a rigid structure. One end of the holding rod 26 is arranged outside the container to constitute an operating end, and the other end is arranged inside the container to constitute a driving end. The driving end is connected to the suction pipe 21 .

[0043] The holding rod 26 extends into the container 1 through the discharge port 12. It is understandable that the direction of the suction pipe 21 and the position on the bottom plate of the container 1 are controlled by controlling the holding rod 26 outside the container 1 to complete the suction process without cleaning the blind area.

[0044] The filter cartridge 25 is made of a multi-layer sintered mesh. It is understandable that the multi-layer sintered mesh can effectively intercept the residual material during the vacuuming process to prevent it from being vacuumed away, reduce the possibility that the residual material will be directly vacuumed away by the vacuuming device, and improve the residual material collection rate.

[0045] The vacuum port 22 is connected to the inner cavity of the filter cartridge 25, and the residual material inlet 241 is connected to the outer cavity of the filter cartridge 25; the residual powder collecting device 2 includes a back-blowing valve 23, one end of which is connected to the inner cavity of the filter cartridge 25 and the other end is connected to the back-blowing gas source. It can be understood that during the vacuuming process, residual materials will accumulate on the filter cartridge 25. The back-blowing valve 23 connected to the back-blowing gas source can back-blow the residual materials accumulated on the filter cartridge 25 into the dust collecting cylinder 24 to improve the suction effect.

[0046] The back-blowing valve 23 is connected to the vacuum port 22. It can be understood that the back-blowing valve blows air directly toward the filter cartridge 25, and the residual material accumulated on the filter cartridge 25 is blown down into the dust collecting cylinder 24 more easily.

[0047] The filter cartridge 25 is a cylindrical structure, and the residual material inlet 241 is arranged along the tangent direction of the filter cartridge 25. It can be understood that the residual material is blown into the dust collecting cylinder 24 around the cross-sectional direction of the filter cartridge 25 to prevent the residual material from accumulating on the filter cartridge 25, resulting in blockage of the suction pipe 21 and the dust collecting cylinder 24 passage.

[0048] A discharge valve 27 is installed at the bottom of the dust collecting barrel, and it can be understood that the residual material collected in the dust collecting barrel is discharged.

[0049] The specific working process of this embodiment is as follows: after the material in the filter washing and drying machine is dried, the discharge valve 131 is opened, the stirring paddle 145 is started to rotate, and it is lowered to the lowest point, and the material slides out of the discharge port under the push of the stirring paddle 145. When no material slides out of the discharge port 12, the stirring paddle 145 is lifted to the highest point, and the stirring paddle 145 stops rotating. The discharge valve 131 is opened and selected to one side, and the polyfluoro suction head 211 is driven by the holding rod 26 to collect the residual powder on the chassis. The opening of the vacuum port 22 forms a vacuum in the dust collection cylinder 24, and the residual material is intercepted by the filter cartridge 25 to avoid being sucked away and collected in the dust collection cylinder 24; after the residual material collection process is completed, the vacuum port 22 is closed and the back-blowing valve 23 is opened to back-blow the residual material attached to the filter cartridge 25. Close the back-blowing valve 23, and open the discharge valve 27 to discharge the material in the dust collection cylinder 24.

[0050] The chassis residual powder collecting device with vacuum material suction function can also be applied to other devices with filtering function and requiring residual material collection.

[0051] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
