[0027] Embodiment 1

[0028] like Figure 1-Figure 6 As shown, the first embodiment of the present invention provides a filtering and impurity removal device for polyether silicone oil processing, including a support leg 1, a shell 2, a cover plate 3, a feed hopper 4, a discharge hopper 5, a collecting frame 6, an injection frame 7, a switching mechanism and a rotating mechanism. A shell 2 is welded to two support legs 1, a cover plate 3 is welded to the shell 2, a feed hopper 4 is welded to the shell 2, the feed hopper 4 is welded to the cover plate 3, a discharge hopper 5 is welded to the shell 2, the discharge hopper 5 is welded to the cover plate 3, two collecting frames 6 are clamped on the cover plate 3, the two collecting frames 6 are used to collect impurities, the two collecting frames 6 are located on both sides of the discharge hopper 5, two injection frames 7 are welded to the shell 2, a switching mechanism is provided on the shell 2, and a rotating mechanism is provided on the switching mechanism.

[0029] In this embodiment, the switching mechanism includes a guide rail 81, an electric slider 82, a mounting frame 83 and a rotating frame 84. The guide rail 81 is fixedly connected in the shell 2, the electric slider 82 is slidably connected to the guide rail 81, the mounting frame 83 is slidably connected to the guide rail 81, the mounting frame 83 is fixedly connected to the electric slider 82, and two rotating frames 84 are rotatably connected to the mounting frame 83, one of the rotating frames 84 is in contact with the feed hopper 4 and the discharge hopper 5.

[0030] In this embodiment, the rotating mechanism includes a motor bracket 91, a drive motor 92, a cam 93, a sliding frame 94, a sliding filter 95 and a tension spring 96. A motor bracket 91 is welded on both sides of the mounting frame 83, and each motor bracket 91 is connected to a drive motor 92 by bolts. A cam 93 is welded on both sides of the mounting frame 83, and each rotating frame 84 is slidably connected to a sliding frame 94. Each sliding frame 94 is in contact with a cam 93. A sliding filter 95 is welded on each sliding frame 94. Each sliding filter 95 is slidably connected to the rotating frame 84, one of the sliding filters 95 is below the feed hopper 4, and four tension springs 96 are connected between each rotating frame 84 and a sliding filter 95.

[0031] The sliding filter 95 is made of a soft material and is used to filter polyether silicone oil.

[0032] When the device shown in this embodiment is in use, at first, gas continuously enters the jet rack 7, so that the jet rack 7 continuously sprays high-pressure gas, and the staff continuously adds polyether silicone oil into the feed hopper 4, and the polyether silicone oil passes through one of the sliding filters 95, and one of the sliding filters 95 filters the polyether silicone oil. The polyether silicone oil is intercepted by one of the sliding filters 95, and the clean polyether silicone oil flows out from the discharge hopper 5. After a period of filtration, there will be a lot of impurities on one of the sliding filters 95. The staff starts the electric slider 82, and the electric slider 82 drives the mounting frame 83, the rotating frame 84, the motor bracket 91, the driving motor 92, the cam 93, the sliding frame 94, the sliding filter 95 and the tension spring 96 to move, and one of the rotating frames 84 The movement will be out of contact with the feed hopper 4 and the discharge hopper 5. The movement of one of the rotating frames 84 will drive one of the sliding filters 95 to move, so that one of the sliding filters 95 will move away from under the feed hopper 4. The movement of the other rotating frame 84 will contact the feed hopper 4 and the discharge hopper 5. The movement of the other rotating frame 84 will drive another sliding filter 95 to move. The other sliding filter 95 will move under the feed hopper 4. Then the staff will start one of the driving motors 92 and close the electric slider 82. The rotation of the driving motor 92 will drive one of the rotating frames 84, the sliding frame 94, the sliding filter 95 and the tension spring 96 to rotate. The rotation of the sliding frame 94 will move along the cam 93. When the sliding frame 94 rotates to the protrusion of the cam 93, the sliding frame 9 4 moves, the movement of the sliding frame 94 will stretch the tension spring 96, and the sliding frame 94 will drive one of the sliding filters 95 to move. When the sliding frame 94 continues to rotate to the recessed position of the cam 93, the tension spring 96 will pull the sliding frame 94 and one of the sliding filters 95 to reset, so that one of the sliding filters 95 moves back and forth quickly. The reciprocating movement of the sliding filter 95 will shake out the impurities, and at the same time, the high-pressure gas ejected by the jet frame 7 will better remove the impurities on one of the sliding filters 95. The removed impurities will fall into the collection frame 6. After a period of time, when more impurities are accumulated on the other sliding filter 95, the staff will turn off one of the driving motors 92. The stop of the driving motor 92 will cause one of the rotating frames 84, the sliding filter 95 to move back and forth quickly. The frame 94, the sliding filter screen 95 and the tension spring 96 stop rotating, and at the same time, one of the rotating frames 84, the sliding frame 94, the sliding filter screen 95 and the tension spring 96 stop rotating and will be in the initial position, and then the staff starts the electric slider 82, and the electric slider 82 drives the mounting frame 83, the rotating frame 84, the motor bracket 91, the drive motor 92, the cam 93, the sliding frame 94, the sliding filter screen 95 and the tension spring 96 to move in opposite directions, so that one of the sliding filter screens 95 moves to the bottom of the feed hopper 4, and finally the staff turns off the electric slider 82 and starts the other drive motor 92, repeating the above steps, and the two sliding filter screens 95 can be cleaned in a cycle, so that the clean sliding filter screen 95 can better filter and remove impurities from the polyether silicone oil,After all the polyether silicone oil is filtered, the staff will pull out the two collection frames 6, pour out the impurities in the two collection frames 6, and then snap the two collection frames 6 back onto the cover plate 3.

[0033] Embodiment 2

[0034] like Figure 6-Figure 8 As shown, the second embodiment of the present invention also provides a filtering and impurity removal device for polyether silicone oil processing. On the basis of the first embodiment, this embodiment also includes a scraping mechanism, which is arranged on the rotating frame 84. The scraping mechanism includes a reciprocating screw 102, a movable frame 103, an overrunning clutch 104, a gear 105 and a rack 106. Each rotating frame 84 is rotatably connected to a reciprocating screw 102, and each reciprocating screw 102 is threadedly connected to a movable frame 103. The reciprocating screw 102 will drive the movable frame 103 to reciprocate. Each rotating frame 84 is in contact with a movable frame 103, and each reciprocating screw 102 is fixedly connected to an overrunning clutch 104, and each overrunning clutch 104 is fixedly connected to a gear 105. Each sliding filter 95 is fixedly connected to a rack 106, and the gear 105 is meshed with the rack 106.

[0035] The overrunning clutch 104 is used for unidirectional power transmission.

[0036] When the device shown in this embodiment is in use, the reciprocating movement of the sliding filter 95 will drive the rack 106 to move reciprocatingly, and the reciprocating movement of the rack 106 will drive the gear 105 to rotate reciprocatingly. Since the overrunning clutch 104 only transmits unidirectional power, the reciprocating screw rod 102 rotates forward, and the forward rotation of the reciprocating screw rod 102 will squeeze the moving frame 103 through the thread to make the moving frame 103 reciprocate. At the same time, when the sliding filter 95 and the sliding frame 94 are lifted by the cam 93, the sliding filter 95 will contact with the moving frame 103. The contact between the sliding filter 95 and the moving frame 103 will cause the filter of the sliding filter 95 to deform. The deformation of the filter of the sliding filter 95 will cause the stuck impurities to fall off. Since the moving frame 103 will reciprocate, the sliding filter 95 can be cleaned more comprehensively, making the sliding filter 95 cleaner, and thus having a better filtering and impurity removal effect on the polyether silicone oil.

[0037] In the device shown in this embodiment, when the sliding filter and the sliding frame are lifted up by the cam, the sliding filter will contact with the moving frame, and the contact between the sliding filter and the moving frame will cause the filter of the sliding filter to deform. The deformation of the filter of the sliding filter will cause the stuck impurities to fall off. Since the moving frame will move back and forth, the sliding filter can be cleaned more comprehensively, making the sliding filter cleaner.

[0038] Embodiment 3

[0039] like Figure 9-10As shown, the second embodiment of the present invention also provides a filtering and impurity removal device for polyether silicone oil processing. On the basis of the second embodiment, the device shown in this embodiment also includes a moving mechanism, which is arranged on the shell 2. The moving mechanism includes a fixed block 111, a slide 112 and a return spring 113. Two fixed blocks 111 are welded on both sides of the shell 2, and the two fixed blocks 111 on the same side are a group. The two fixed blocks 111 in the same group are slidably connected to a slide 112. Each slide 112 is connected to two fixed blocks 111 with two return springs 113.

[0040] In this embodiment, a pushing mechanism is also included. The pushing mechanism is arranged on the slide 112. The pushing mechanism includes a transmission rod 114 and a top plate 115. A transmission rod 114 is welded to each slide 112. The two transmission rods 114 are slidably connected to the discharge hopper 5. A top plate 115 is welded to each transmission rod 114.

[0041] When the device shown in this embodiment is in use, the rotating frame 84 rotates to a vertical state to contact the slide 112 and squeeze the slide 112 to move upward. The upward movement of the slide 112 compresses the return spring 113. The upward movement of the slide 112 drives the transmission rod 114 and the top plate 115 to move upward. The upward movement of the top plate 115 pushes the sliding filter 95 located below the feed hopper 4 to move upward. After the rotating frame 84 rotates and disengages from the slide 112, the slide 112 is reset driven by the return spring 113, and the sliding filter 95 is reset driven by the tension spring 96, and then reciprocates. The reciprocating movement of the sliding filter 95 drives the rack 106 to reciprocate. The reciprocating movement of the rack 106 will drive the reciprocating screw 102 to rotate through the overrunning clutch 104 and the gear 105, and the rotation of the reciprocating screw 102 will drive the moving frame 103 to move back and forth. The reciprocating movement of the moving frame 103 will stir the impurities on the sliding filter 95, so that the impurities on the sliding filter 95 will not stay and accumulate in one place for a long time, and the impurities are prevented from being stuck in the sliding filter 95 under the impact of the polyether silicone oil. At the same time, because the moving frame 103 continuously stirs the impurities on the sliding filter 95, it makes it difficult for the sliding filter 95 to be blocked by impurities, so that the filtering effect of the sliding filter 95 is better, and the filtering and impurity removal effect of the polyether silicone oil is further improved.

[0042] In the device shown in this embodiment, the rotation of the rotating frame will cause the slide frame and the top plate to move back and forth, the reciprocating movement of the top plate will push the sliding filter below the feed hopper to move back and forth, the reciprocating movement of the sliding filter will drive the reciprocating screw to rotate through the rack, the overrunning clutch and the gear, the rotation of the reciprocating screw will drive the moving frame to move back and forth, the reciprocating movement of the moving frame will stir the impurities on the sliding filter, so that the impurities on the sliding filter will not stay and accumulate in one place for a long time, avoiding the impurities from being stuck in the sliding filter under the impact of the polyether silicone oil, and at the same time, because the moving frame constantly stirs the impurities on the sliding filter, it makes it difficult for the sliding filter to be blocked by impurities, so that the filtering effect of the sliding filter is better, further improving the filtering and impurity removal effect of the polyether silicone oil.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
