Detailed Implementation

[0020] Please see Figures 1-4 In this embodiment of the present invention, a papermaking defoamer processing device includes a processing device base 1, an upper frame 2 at the upper end of the processing device base 1, and the internal spaces of the processing device base 1 and the upper frame 2 are connected. The upper frame 2 is provided with a feed inlet 3, through which the raw materials to be processed for defoamer production can be poured into the interior of the processing device base 1 for filtration and other processing. The side wall of the processing device base 1 is provided with a discharge outlet 4, through which the separated impurities and unreacted raw materials can be discharged. The processing device base 1 can be opened (not shown in the figure) to facilitate the workers to take out the qualified raw materials after separation for subsequent processing.

[0021] A movable column 6 is slidably connected to the upper center of the processing device base 1. A rotating column 7 is sleeved on and rotatably connected to the movable column 6. The lower end of the rotating column 7 passes through and is fixedly connected to the connecting rod 8. A lower ring 9 is fixedly connected to the connecting rod 8. The upper end of the lower ring 9 is connected to an upper ring 11 through an annular screen 10. A screen (not shown in the figure) is also provided at the gap between the lower ring 9 and the connecting rod 8. When the raw material enters the processing device base 1, it will be concentrated inside the lower ring 9, the annular screen 10 and the upper ring 11, and will be filtered by the annular screen 10.

[0022] A drive cylinder 5 is installed at the upper end of the upper frame 2. The output shaft of the drive cylinder 5 passes through the interior of the upper frame 2 and is fixedly connected to the moving column 6. When the drive cylinder 5 is working, it can drive the raw material to move up and down, thereby accelerating the filtration efficiency of the raw material. A limit column 12 is fixedly connected to the inner wall of the lower end of the processing device base 1. The rotating column 7 is sleeved on the limit column 12. A slider 13 is fixedly connected to the outer wall of the limit column 12. A spiral groove (not shown in the figure) adapted to the slider 13 is opened on the inner wall of the rotating column 7. When the rotating column 7 moves up and down, under the limit of the slider 13, the rotating column 7 rotates, thereby rotating the raw material and further accelerating the filtration efficiency.

[0023] A horizontal plate 14 is fixedly connected to the outer wall of the moving column 6. A first bevel gear 15 is rotatably connected inside the horizontal plate 14. A rotating column 16 is fixedly connected to the lower end of the first bevel gear 15. A cleaning brush 17 is fixedly connected to the outer wall of the rotating column 16. The cleaning brush 17 contacts the annular screen 10 to clean and unclog the annular screen 10, ensuring its good filtration and separation effect. A second bevel gear 18 is rotatably connected to the horizontal plate 14. The first bevel gear 15 and the second bevel gear 18 are in a meshing state. A drive gear 19 is fixedly connected to the second bevel gear 18. A tooth groove (not shown in the figure) that meshes with the drive gear 19 is opened on the inner wall of the processing device base 1. When the horizontal plate 14 moves up and down with the moving column 6, the drive gear 19 rotates under the action of the tooth groove, thereby rotating the cleaning brush 17. The rotation direction is opposite to the rotation direction of the annular screen 10, ensuring the cleaning effect.

[0024] The working principle of this utility model is as follows: When it is necessary to filter and process the defoamer raw material, the raw material can first be poured into the internal screen and annular screen 10 of the processing device base 1 through the feed port 3. The annular screen 10 can separate impurities and unreacted raw materials, which are then discharged through the discharge port 4 for centralized processing. At the same time, the drive cylinder 5 starts to work, and its output shaft performs intermittent up-and-down reciprocating motion, thereby driving the moving column 6 and rotating column 7 to move up and down, realizing the shaking of the raw material and accelerating the filtration and separation efficiency. When the rotating column 7 moves up and down, under the limit of the slider 13 on the limit column 12, the rotating column 7 will... The rotation of the column 6 further accelerates the filtration efficiency of the raw material. When the column 6 moves, it also drives the horizontal plate 14 to move synchronously. At this time, the second bevel gear 18 and the drive gear 19 move with the horizontal plate 14. Under the limit of the tooth groove on the inner wall of the processing device base 1, the drive gear 19 can drive the second bevel gear 18 to rotate. When the second bevel gear 18 rotates, it can drive the first bevel gear 15 that meshes with it to rotate, thereby driving the rotating column 16 and the unblocking brush 17 below to rotate, thereby unblocking and cleaning the annular screen 10 and ensuring its good filtration and separation effect.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
