The inner wall of the top cover 331 is provided with a rotating thread. The top of the rotating filter barrel 31 is provided with a rotating thread that cooperates with the inner wall of the top cover 331. The surfaces of the filter cylinder 332 and the rotating filter barrel 31 are provided with a plurality of filter holes.
[0028] Through the above scheme: the rotating device 3 rotates rapidly, causing the defoamer inside the rotating filter barrel 31 to be thrown out by centrifugal force. A rotating shaft 34 is fixed to the bottom of the rotating filter barrel 31, and gears 36 are provided at both the rotating shaft 34 and the output end of the motor 35, with the two gears 36 meshing together. Six fixed posts 32 are fixedly connected to the top surface of the rotating filter barrel 31, and each of the six fixed posts 32 has a ball bearing rotatably connected to its end. The ball bearing is in rolling contact with the outer ball bearing groove 2, and the ball bearing and the ball bearing groove 2 can cooperate with each other, increasing its stability during rotation and preventing the rotating filter barrel 31 from losing its balance. The defoamer flows into the rotating filter barrel 31 after passing through the preliminary filtration device 33 for filtration. The size, thickness, and number of layers of filter paper can be set according to actual needs. The defoamer is first filtered through the filter paper on the inner wall, and then thrown out through the filter holes on the surface of the rotating filter barrel 31 and flows into the collection tank. It then flows into the filter box 81 through the pipe 9 along the collection tank. The top cover 331 can be installed on the top of the rotating device 3 to prevent the defoamer from splashing during rotation. The bottom of the second water inlet pipe 333 is fixedly connected to the filter cylinder 332, which can filter out some larger particulate impurities first. The inner wall of the top cover 331 is provided with a rotating thread that can be used with the top screw of the rotating filter barrel 31 to make the connection tighter and prevent it from falling off. The surfaces of the filter cylinder 332 and the rotating filter barrel 31 are provided with several filter holes to facilitate the smooth discharge of the defoamer during filtration.
[0029] In this embodiment, the circulation device 7 includes a storage tank 71, which stores unfiltered defoamer. The bottom of the storage tank 71 is provided with a diversion device 8, which includes a filter box 81. A filter screen 82 is fixedly connected to the inner wall of the filter box 81, and the filter screen 82 is inclined to the right. The water outlet pipe 10 is below the filter screen 82. The inclined end of the filter screen 82 is provided with a trapezoidal hollow tube 83, and the right end of the trapezoidal hollow tube 83 is fixedly connected with a conduit 72. The other end of the conduit 72 is fixedly connected to the right side of the storage tank 71. The outer shell 1 is provided with a collection tank that works with the rotating device 3. A through pipe 9 is provided on the right side of the collection tank, and the through pipe 9 is fixedly connected to the filter box 81.
[0030] With the above scheme, when the defoamer flows into the filter box 81 through the pipe 9, it is filtered by the inclined filter screen 82. Part of it is filtered to the bottom and enters the next process through the water outlet pipe 10, while the insufficiently filtered part enters the storage box 71 for re-filtration along the inclined angle through the trapezoidal hollow pipe 83 and the conduit 72, which greatly increases the effect of the filtered product.
[0031] It should be noted that this utility model is a defoamer filtration device. First, filter paper is installed in the filter cylinder 332 and rotating filter barrel 31 of the device according to actual needs. The defoamer to be filtered is poured into the storage tank 71 and the device is started through the control panel 6. After the device is started, the defoamer is pumped into the rotating device 3 through the first water inlet pipe 4 by the water pump 5. The rotating device 3 rotates rapidly, causing the defoamer in the rotating filter barrel 31 to be thrown out due to centrifugal force. The bottom of the rotating filter barrel 31 is fixed with a rotating shaft 34, and the rotating shaft 34 is connected to the motor 35. Each end is equipped with a gear 36, and two gears 36 are meshed together. Six fixed posts 32 are fixedly connected to the top surface of the rotating filter barrel 31, and each of the six fixed posts 32 is rotatably connected to a ball bearing. The ball bearing is in rolling contact with the outer ball bearing groove 2. The ball bearing and the ball bearing groove 2 can cooperate with each other to increase its stability during rotation and prevent the rotating filter barrel 31 from losing its balance. The defoamer flows into the rotating filter barrel 31 for filtration after passing through the preliminary filtration device 33. The contents of the rotating filter barrel 31 can be set according to actual needs. The size, thickness, and number of layers of filter paper are considered. The defoamer first passes through the inner wall filter paper, then is flung out through the filter holes on the surface of the rotating filter barrel 31 and flows into the collection tank. It then flows along the collection tank through the pipe 9 into the filter box 81. The top cover 331 can be installed on top of the rotating device 3 to prevent defoamer splashing during rotation. A filter cylinder 332 is fixedly connected to the bottom of the second water inlet pipe 333, which can preferentially filter out some larger particulate impurities. The inner wall of the top cover 331 has a rotating thread that can be used with the spiral on the top of the rotating filter barrel 31, making the connection more secure. To prevent detachment, both the filter cartridge 332 and the rotating filter barrel 31 have several filter holes on their surfaces to facilitate the smooth discharge of the defoamer during filtration. When the defoamer flows into the filter box 81 through the pipe 9, it is filtered by the inclined filter screen 82. Part of the filtered material reaches the bottom and enters the next process through the outlet pipe 10, while the insufficiently filtered material enters the storage box 71 for re-filtration along the inclined angle through the trapezoidal hollow pipe 83 and the conduit 72. This greatly increases the effectiveness of the filtered product. The above components work together to make the device more convenient and efficient.
