The recovery bin 1 is arranged above the support frame 53, the slurry barrel 2 is arranged on the support plate 52, the filter element 6 to be recovered slurry is installed in the recovery bin 1, and the air source pipeline 3 is arranged on the recovery bin 1. The air source pipeline 3 is connected to an external air source to introduce positive pressure into the filter element 6 to blow the slurry in the filter element 6 into the slurry barrel 2. In this embodiment, the slurry barrel 2 is a stainless steel barrel.

[0028] Reference Figure 1 and Figure 2The recovery bin 1 is a rectangular hollow shell structure. The recovery bin 1 is mounted above the support frame 53. A movable baffle 11 is slidably provided on one side wall of the recovery bin 1. The recovery bin 1 can be closed or opened by sliding the movable baffle 11. When it is necessary to blow positive pressure to the filter element 6 to recover the slurry, the sliding movable baffle 11 closes the recovery bin 1 to reduce the possibility of slurry splashing during the recovery process. When the sliding movable baffle 11 opens the recovery bin 1, the items in the recovery bin 1 can be taken out.

The quick-release clamp is used to achieve the connection and fixation between the bin cover 4 and the installation position 13. The structure is simple and the installation and disassembly are convenient, which facilitates the installation of the filter element 6. A ejector pin 41 is provided in the bin cover 4. The ejector pin 41 is arranged vertically downward. After the filter element 6 for the slurry to be recovered is installed in the installation position 13, the ejector pin 41 can push open the one-way valve in the filter element 6 to allow positive pressure to be introduced into the filter element 6.

[0031] Reference Figure 1 、 Figure 4 and Figure 5The gas source pipeline 3 includes an air pipe 31, a manual valve switch 32 and a pressure regulating valve 33. The air pipe 31 connects the pressure regulating valve 33 and the compartment cover 4. The manual valve switch 32 is arranged in the transmission path of the air pipe 31. The manual valve switch 32 is used to adjust the opening and closing of the air circuit of the air pipe 31; the input end of the pressure regulating valve 33 is connected to the air source of the factory, and the output end is connected to the air pipe 31 to adjust the air pressure of the air circuit.

[0032] Specifically, the bin cover 4 is provided with an air inlet 42, on which a third clamping joint is fixedly provided, and the third clamping joint is a flange structure. The end of the air pipe 31 is connected to a threaded straight-through 311, and the threaded straight-through 311 is fixedly connected to a fourth clamping joint, which is also a flange structure. The bin cover 4 is detachably provided with a second quick-release clamp 44. When in use, the third clamping joint and the fourth clamping joint are fixed to each other by the second quick-release clamp 44, so that the bin cover 4 can be firmly connected to the air pipe 31. The quick-release clamp is used to achieve the connection and fixation between the bin cover 4 and the air pipe 31, which is convenient for installation and removal, facilitates the installation and removal of the bin cover 4, and improves work efficiency.

[0033] Furthermore, in one embodiment, a diverter five-way valve 34 is further included. The diverter five-way valve 34 is fixedly mounted on the outside of the recovery bin 1. Four mounting positions 13 are provided on the top of the recovery bin 1. The input end of the diverter five-way valve 34 is connected to the pressure regulating valve 33 via an air pipe 31, and the four output ends of the diverter five-way valve 34 are connected to the four bin covers 4 via air pipes 31. By providing the diverter five-way valve 34, a single air source can apply positive pressure to the filter elements 6 in each of the four mounting positions 13. Furthermore, the opening and closing of each air pipe 31 can be individually controlled by a manual valve switch 32 on the air pipe 31 corresponding to each bin cover 4, thereby achieving independent control of each mounting position 13.

[0034] Furthermore, a discharge hole 14 is formed at the bottom of the recovery bin 1. A recovery filter 15 is detachably fixed in the discharge hole 14. The recovery filter 15 is disposed below the mounting position 13. The slurry barrel 2 is disposed below the recovery filter 15. The slurry discharged from the filter element 6 is filtered through the recovery filter 15 and then flows into the slurry barrel 2. Specifically, in this embodiment, the recovery filter 15 is a 100-mesh filter.

[0035] In some embodiments, the recovery bin 1 is fixedly provided with a guide hopper 16, and the guide hopper 16 is located below the discharge hole 14. The guide hopper 16 is used to guide the slurry flowing out of the filter element 6 so that the filter element 6 flows smoothly into the recovery barrel.

[0036] The principle of collecting the slurry in the filter element 6 in the present invention is as follows:

[0037] Before operating the mechanism, first rotate the hand valve switch 32 to the closed position, then adjust the knob of the pressure regulating valve 33 to the lowest pressure state, and then connect the pressure regulating valve 33 to the air source of the factory; secondly, open the first quick-release clamp 43, remove the compartment cover 4, place the filter element 6 into the installation position 13, and then align the ejector pin 41 on the compartment cover 4 with the corresponding hole position on the filter element 6 to install the compartment cover 4, and lock the first quick-release clamp 43 to fix the filter element 6; then operate the mechanism, adjust the knob of the hand valve switch 32 to the open position, and slowly adjust the knob of the pressure regulating valve 33 so that the factory air source can slowly enter the filter element 6 through the air pipe 31. By adjusting the knob of the pressure regulating valve 33 to increase the air pressure, the slurry outflow can be observed through the transparent visual baffle 12. The slurry is filtered through the recovery filter 15 and then collected in the slurry bucket 2 below. When the recovery is completed, the manual valve switch 32 is first turned to the closed position, and then the first quick-release clamp 43 is opened to remove the filter element 6 that has been recovered by the slurry, thus completing the slurry recovery process for one set of filter elements 6. The above steps can then be repeated to recover the slurry from the next set of filter elements 6. After all the filter elements 6 in the recovery bin 1 have been removed, the recovery filter 15 can be cleaned or replaced.
