[0020] It should be further explained that the drawings and implementation modes of the present invention mainly describe the concept of the present invention. On the basis of this concept, the specific forms and settings of some connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described. However, on the premise that those skilled in the art understand the concept of the present invention, those skilled in the art can implement the above-mentioned specific forms and settings in a well-known manner.

[0021] When an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element.

[0022] The directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself. The directions or positional relationships indicated by the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, and "several" means one or more, unless otherwise clearly and specifically defined.

[0025] An insulating slurry recovery device provided by the present invention is now described.

[0026] like Figure 1 and Figure 2 As shown, one embodiment of the present invention provides an insulating slurry recovery device, including a plurality of insulating material recovery boxes 1 and a plurality of conductive material recovery boxes 2, wherein the insulating material recovery box 1 is used for pouring dissolved insulating slurry, and the conductive material recovery box 2 is used for pouring dissolved conductive slurry; the bottom of the insulating material recovery box 1 is connected to an insulating material recovery pipe 11, and the ends of all insulating material recovery pipes 11 are connected to an insulating material recovery main pipeline 12; the bottom of the conductive material recovery box 2 is connected to a conductive material recovery pipe 21, and the ends of all conductive material recovery pipes 21 are connected to a conductive material recovery main pipeline 22; a set of filtering mechanisms 3 are respectively connected to the ends of the insulating material recovery main pipeline 12 and the ends of the conductive material recovery main pipeline 22.

[0027] Compared with the prior art, the insulating slurry recovery device provided in the present embodiment distinguishes and collects the insulating slurry and the conductive slurry through the insulating material recovery box 1 and the conductive material recovery box 2, and then sends them into two sets of filtering mechanisms 3 for separate filtration after passing through the insulating material recovery pipe 11 and the conductive material recovery pipe 21. The filtered insulating slurry and the conductive slurry can be separately prepared without considering the proportion of the components of the insulating slurry and the conductive slurry, which facilitates the two to be separately prepared into qualified slurries again.

[0028] like Figure 2 and Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The filtering mechanism 3 includes an outer cylinder 31, a filter cartridge 32, a driving assembly 33, a partition plate 34 and a drain pipe 35; the outer cylinder 31 is fixedly mounted on the ground, the filter cartridge 32 is coaxially rotatably connected to the inner side of the outer cylinder 31, both ends of the filter cartridge 32 pass through the outer cylinder 31 and are provided with upper and lower openings, the part of the filter cartridge 32 located inside the outer cylinder 31 has filter holes, and the ends of the insulating material recovery main pipeline 12 and the conductive material recovery main pipeline 22 are inserted into the corresponding top openings of the filter cartridge 32; the driving assembly 33 is arranged on the outer cylinder 31 and is used to drive the filter cartridge 32 to rotate; the partition plates 34 have a plurality of them and are equidistantly spaced up and down on the inner circumference of the filter cartridge 32, and the partition plates 34 divide the internal space of the filter cartridge 32 into an S-shaped multi-segment curve; the drain pipe 35 is connected to the bottom of the outer cylinder 31.

[0029] When filtering insulating slurry or conductive slurry, the slurry enters from the top of the filter cartridge 32, and the driving assembly 33 drives the filter cartridge 32 to rotate, and cycles according to the fast-slow-fast speed, so that the slurry in the filter cartridge 32 is thrown onto the inner wall of the filter cartridge 32 by centrifugal force, and then continues to flow to the partition plate 34 below by its own gravity and fluidity, and repeats this process until the slurry is discharged from the bottom of the filter cartridge 32 after multiple centrifugal filtrations. This not only improves the filtering effect of the slurry, but also eliminates the need to clean the residual slurry inside the filter cartridge 32, thereby improving the operating efficiency.

[0030] Furthermore, the partition plate 34 is tilted downward from the inner wall of the filter cartridge 32 to the axial direction, which can improve the efficiency of the slurry flowing downward after centrifugation and make the slurry flow out of the filter cartridge 32 more completely.

[0031] like Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The driving assembly 33 includes a driving motor 341, a driving gear 342 and a driving gear ring 343. The driving motor 341 is arranged at the bottom of the outer cylinder 31, the driving gear 342 is coaxially fixed on the output shaft of the driving motor 341, and the driving gear ring 343 is coaxially fixedly sleeved at the bottom position of the filter cylinder 32, and the driving gear 342 and the driving gear ring 343 are meshed.

[0032] The driving motor 341 is started to rotate the driving gear 342 , and the driving gear 342 drives the driving gear ring 343 and the filter cartridge 32 to rotate, thereby improving the rotation efficiency of the filter cartridge 32 .

[0033] like Figure 3 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: A cleaning assembly 4 for cleaning the filter holes on the filter cartridge 32 is arranged in the outer cylinder 31; the cleaning assembly 4 includes an annular plate 41, an annular cleaning brush 42, a screw 43, a guide rod 44 and a cleaning motor 45; the annular plate 41 is coaxially arranged in the outer cylinder 31, the annular cleaning brush 42 is arranged on the inner side of the annular plate 41 and contacts with the outer peripheral surface of the filter cartridge 32; the screw 43 is rotatably connected in the outer cylinder 31 and parallel to the filter cartridge 32, the guide rod 44 is fixed in the outer cylinder 31 and parallel to the screw 43, the annular plate 41 is threadedly connected to the screw 43 and penetrated by the guide rod 44; the cleaning motor 45 is arranged on the outer cylinder 31, and the output shaft of the cleaning motor 45 is coaxially fixed with the screw 43.

[0034] Specifically, the annular plate 41 and the annular cleaning brush 42 are located at the top of the outer cylinder 31 in an initial state.

[0035] When it is necessary to clean the filter holes on the filter cartridge 32, start the cleaning motor 45 to rotate the screw 43, and the screw 43 drives the annular plate 41 to descend along the direction of the guide rod 44, so that the annular cleaning brush 42 brushes the filter holes on the filter cartridge 32, thereby improving the cleaning efficiency of the filter holes on the filter cartridge 32.

[0036] like Figures 4 to 6 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The annular plate 41 is equally divided into a plurality of fan-shaped single plates 411 along its own circumferential direction, and adjacent single plates 411 are radially slidably connected along their own axes; the annular cleaning brush 42 is divided into a plurality of single brushes 421 following the division position of the annular plate 41; a plurality of rows of arc-shaped protrusions 5 are arranged on the inner circumferential surface of the outer cylinder 31, and when the outer side of the single plate 411 not connected to the screw 43 and the guide rod 44 is squeezed by the arc-shaped protrusion 5, the corresponding single brush 421 is compressed and pressed against the outer wall of the filter cylinder 32; after the single plate 411 is not squeezed by the arc-shaped protrusion 5, the resilience of the single brush 421 drives itself and the single plate 411 to reset; each row of arc-shaped protrusions 5 is arranged at equal intervals, and the outer cylinder 31 is provided with a plurality of groups of adjustment mechanisms 6, and the adjustment mechanism 6 is used to drive the arc-shaped protrusions 5 of the corresponding row to move vertically by a spacing distance.

[0037] Specifically, in this embodiment, the annular plate 41 is divided into six fan-shaped single plates 411, the screw rods 43 and the guide rods 44 are arranged opposite to each other, two opposite single plates 411 are connected to the corresponding screw rods 43 and the guide rods 44, and the other four single plates 411 are slidably connected to both sides of the above two single plates 411. The intersection positions of the edges of adjacent single brushes 421 can cross each other.

[0038] In order to further improve the cleaning effect of the filter holes on the filter cartridge 32, when the annular plate 41 drives the annular cleaning brush 42 to rise and fall, the arc-shaped protrusion 5 will squeeze the outer side of the corresponding single plate 411, and this single plate 411 drives the corresponding single brush 421 to press against the filter cartridge 32, so that each single brush 421 can clean the filter holes on the filter cartridge 32 more thoroughly; after the annular plate 41 descends to the bottom of the outer cylinder 31, the height position of each column of arc-shaped protrusions 5 is adjusted by the adjustment mechanism 6, so that the arc-shaped protrusions 5 are moved to a position in the outer cylinder 31 where they were not originally there, and the corresponding single brush 421 can clean the filter holes in the vertical direction of the filter cartridge 32 that have not been squeezed and cleaned before more thoroughly when it rises, so that the filter holes on the entire filter cartridge 32 can be efficiently cleaned.

[0039] Furthermore, the single brush 421 on the inner side of the single plate 411 connected to the screw 43 and the guide rod 44 is fixed to the other adjacent single plates 411. Since the single plates 411 connected to the screw 43 and the guide rod 44 cannot slide laterally, the single brushes 421 on the two single plates 411 are relatively fixed to the adjacent slidable single plates 411 to ensure that the filter holes on the entire filter cartridge 32 can be cleaned.

[0040] like Figure 6 to Figure 7 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The adjusting mechanism 6 comprises an adjusting plate 61, an adjusting spring 62, a positioning assembly 63 and an unlocking assembly 64. The adjusting plate 61 is vertically slidably arranged on the inner wall of the outer cylinder 31. The adjusting plate 61 does not protrude from the inner wall of the outer cylinder 31. The adjusting spring 62 is connected between the inner bottom of the outer cylinder 31 and the adjusting plate 61. Each row of arc-shaped protrusions 5 is fixed on the corresponding adjusting plate 61. The positioning assembly 63 is arranged at the bottom of the outer cylinder 31 and is used to fix the position of the adjusting plate 61. At this time, the adjusting spring 62 is in a compressed state. The unlocking assembly 64 is used to release the position fixation of the adjusting plate 61 by the positioning assembly 63. At this time, the adjusting spring 62 drives the adjusting plate 61 to move a distance equal to the spacing between the arc-shaped protrusions 5.

[0041] When the annular plate 41 and the annular cleaning brush 42 descend, the positioning assembly 63 keeps the adjustment plate 61 and the corresponding row of arc-shaped protrusions 5 in place. When the annular plate 41 descends to the bottom of the outer cylinder 31, the unlocking assembly 64 releases the positioning assembly 63 from fixing the position of the adjustment plate 61, so that the adjustment plate 61 and the corresponding row of arc-shaped protrusions 5 move upward by a distance equal to the spacing between the arc-shaped protrusions 5, thereby improving the position adjustment efficiency of each row of arc-shaped protrusions 5.

[0042] like Figure 6 to Figure 7 As shown, the present invention provides a specific implementation method based on the above implementation method as follows: The positioning assembly 63 includes an insert plate 631 and a return spring 632. A receiving groove 311 is provided at the bottom of the outer cylinder 31. The insert plate 631 slides horizontally in the receiving groove 311. A slot 611 is provided on one side of the bottom of the adjustment plate 61 for the insert plate 631 to be inserted into. When the end of the insert plate 631 is located in the slot 611, the return spring 632 is in a natural state. The unlocking assembly 64 is used to drive the insert plate 631 to disengage from the slot 611.

[0043] The unlocking component 64 includes an extrusion column 641 and a force-bearing portion 642. The extrusion column 641 is fixed at the bottom of the corresponding single board 411, and the force-bearing portion 642 is arranged on the plug board 631 and is squeezed by the extrusion column 641; the bottom of the extrusion column 641 is hemispherical, and the force-bearing portion 642 is an inclined groove opened on the top surface of the plug board 631. When the bottom of the extrusion column 641 squeezes the inclined surface in the force-bearing portion 642, the plug board 631 moves in the direction away from the slot 611; the top surface of the plug board 631 inserted into the slot 611 is inclined.

[0044] Specifically, after the plug plate 631 is disengaged from the slot 611, the adjusting spring 62 drives the adjusting plate 61 to move upward, and at this time the top of the adjusting plate 61 passes through the upper surface of the outer cylinder 31; after the annular plate 41 rises and resets to the initial state, the adjusting plate 61 is manually pressed so that its bottom end presses the inclined surface of the end of the plug plate 631 until the end of the plug plate 631 is inserted into the slot 611 again, so as to facilitate the next cleaning of the filter cartridge 32.

[0045] When the annular plate 41 and the annular cleaning brush 42 are in the initial state and the descending state, the end of the plug plate 631 is always located in the slot 611, which improves the position stability of the adjustment plate 61 and the corresponding row of arc-shaped protrusions 5. When the single plate 411 descends to the bottom of the outer cylinder 31, the extrusion column 641 on the single plate 411 is inserted downward into the force-bearing part 642 on the corresponding plug plate 631, and as the single plate 411 and the extrusion column 641 descend, the extrusion column 641 continuously squeezes the force-bearing part 642 to make the plug plate 631 gradually move away from the slot 611 until it is disengaged, at which time the elastic force of the adjustment spring 62 drives the adjustment plate 61 and the corresponding row of arc-shaped protrusions 5 to move upward, which improves the position switching efficiency of each row of arc-shaped protrusions 5 according to the lifting direction of the annular plate 41 and the annular cleaning brush 42.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
