[0018] Example 1 like Figure 1-5 As shown, this utility model provides a filtration device for heat treatment quenching liquid, which has a filter box 1. The filter box 1 has symmetrical material inlets on its side wall. Each material inlet is provided with a connecting plate 11. Each connecting plate 11 and the side wall of the filter box 1 are provided with multiple fixing bolts. Each connecting plate 11 is fixedly connected with a handle. The filter box 1 is equipped with two synchronously rotating filter side screens 2, and the filter box 1 is equipped with an adjustment component for adjusting the included angle of the filter side screens 2.

[0019] Optionally, in the above technical solution, the adjusting component has a vertically movable bushing 31, and the lower ends of the movable rod 32 are hinged to the left and right sides of the bushing 31 through the hinge seat 33. The upper end of the movable rod 32 is hinged to the filter side screen plate 2 through the hinge seat 33. The lower hinge seat 33 is vertically slidably connected to the bushing 31, and the upper hinge seat 33 is fixedly installed on the bottom wall of the filter side screen plate 2.

[0020] Optionally, in the above technical solution, a slide rod 34 is fixedly installed inside the filter box 1 and below the filter side screen plate 2, and the bushing 31 is vertically slidably connected to the slide rod 34. Among them, the support plate 38 is fixedly installed on the inner wall of the filter box 1, and the slide rod 34 is fixedly installed on the top wall of the support plate 38. The slide rod 34 is located in the middle of the horizontal and vertical directions of the filter box 1. A rack 35 is fixedly installed on one side of the bushing 31, and a gear 36 is meshed on the rack 35. The gear 36 is rotatably connected to the filter box 1.

[0021] Optionally, in the above technical solution, vertically arranged sliding grooves 12 are provided on the front and rear inner walls of the filter box 1. Square sliders 13 are slidably connected in the sliding grooves 12, and rotating shafts 20 are fixedly connected on the opposite side of the two sliders 13. A connecting block A21 is fixedly installed on the right wall of the left filter side screen plate 2, and a connecting block B22 is fixedly installed on the left wall of the right filter side screen plate 2. Both connecting blocks A21 and B22 are sleeved on the rotating shaft 20 and rotatably connected to it.

[0022] Optionally, in the above technical solution, an inclined guide plate 3 is fixedly installed on the inner wall of the filter box 1 and at a position opposite to the two feed inlets.

[0023] Optionally, in the above technical solution, a cam 41 is rotatably connected above the filter side screen plate 2. One end of the cam 41 is fixedly mounted on the rotating rod B42, and the other end of the cam 41 is in intermittent contact with the filter side screen plate 2.

[0024] Among them, the end of the cam 41 with the smallest radius is in intermittent contact with the filter side screen plate 2.

[0025] When the bushing 31 is at the lowest end of its stroke, causing the filter side screen plate 2 to tilt, there is a certain gap between the lowest end of the filter side screen plate 2 and the inner wall of the adjacent filter box 1. The width of the guide plate 3 is greater than this gap, and its length is consistent with the longitudinal length of the filter side screen plate 2. At this time, the bottom end of the filter side screen plate 2 abuts against the guide plate 3, which facilitates the flow of impurities from the feed inlet. The guide plate 3 is tilted, and its tilt direction is consistent with that of the filter side screen plate 2 on the same side.

[0026] Furthermore, baffles 23 are fixedly installed on the opposite side of the filter box 1. The bottom wall of the baffles 23 abuts against the top wall of the horizontal filter side screen 2, limiting the degree of rotation and making it easier to keep the filter side screen 2 in a horizontal state.

[0027] Furthermore, dovetail grooves 310 are provided on the opposite side walls of the bushing 31, and matching dovetail blocks are vertically slidably connected in the dovetail grooves 310. The lower hinge seat 33 is fixedly installed on the dovetail block to provide guidance for the vertical movement of the lower hinge seat 33.

[0028] Preferably, the bushing 31 is slidably connected to the slide rod 34 via a linear bearing.

[0029] Among them, gear 36 is fixedly installed on rotating rod A37, rotating rod A37 is rotatably connected to filter box 1 and extends out of filter box 1.

[0030] Furthermore, a spring 14 is fixedly installed between the bottom wall of the slider 13 and the bottom wall of the groove 12; wherein, the spring 14 is a compression spring, and the two ends of the spring 14 are tightly ground flat.

[0031] Preferably, a damper can be provided inside the spring 14; wherein, the spring 14 must be able to withstand Figure 4 The total weight of all components is constant, and there is no plastic deformation; when the cam 41 rotates, the spring 14 can be compressed.

[0032] Working principle: During filtration, the two filter side screens 2 are in a horizontal state, allowing the quenching liquid to flow into the filter box. The bushing 31 is at the highest end of the stroke, the lower end of the movable rod 32 is located at the lower part of the bushing 31, and a square limiting rod is inserted into the slider 13 through the slot 15. When it is necessary to discharge the debris filtered from the filter side screen plate 2, remove the connecting plate 11 and rotate the two filter side screen plates 2 in reverse, that is, the left end rotates counterclockwise and the right end rotates clockwise, until they abut against the guide plate 3. At this time, the bushing 31 is at the lowest end of the stroke and the lower end of the movable rod 32 is at the upper part of the bushing 31. When it is necessary to strike the filter side screen plate 2, remove the limiting rod from the slot 15 and the slider 13 to remove the restriction on the height of the rotating shaft 20. Rotate the rotating rod B42 to drive the cam 41 to rotate. The cam 41 strikes the filter side screen plate 2, specifically by striking the connecting block A21 and the connecting block B22. During the striking process, connecting blocks A21 and B22 are subjected to force, causing the filter side screen plate 2 to move downward. The slider 13 drives the rotating shaft 20 to move downward along the slide groove 12, compressing the spring 14. After one strike is completed, the spring 14 causes the slider 13 to return to its original position, vibrating the filter side screen plate 2. The slider 13 always slides within the slide groove 12, and the filter side screen plate 2 will not shift. During the striking process, the filter side screen plate 2 moves downward as a whole, and the lower end of the movable rod 32 slides down along the dovetail groove 310 on the side wall of the bushing 31. The rotation method and angle adjustment method of the filter side screen plate 2 are as follows: rotate the rotating rod A37 to drive the gear 36 to rotate clockwise, which drives the rack 35 meshing with it to move down. The rack 35 drives the bushing 31 to move down along the sliding rod 34, and also drives the lower end of the movable rod 32 to move down. Under the action of the hinge at both ends of the movable rod 32, the two filter side screen plates 2 are tilted and the angle becomes smaller.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
