Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen anti-clogging technology, specifically a composite sand mill screen anti-clogging device. Background Technology
[0002] The compound sand mill is a highly efficient dispersing and grinding equipment widely used in fine chemical industries such as coatings, inks, pigments, dyes, pesticides, and cosmetics. Its core function is to disperse and refine solid particles to the micron or even nanometer level by subjecting materials to intense impact, shearing, and friction through grinding media (such as glass beads, zirconium beads, etc.). During the operation of the sand mill, the screen is one of the key components. Its function is to separate the qualified ground material (within the required particle size) from the grinding media and incompletely ground coarse particles, preventing the media from being discharged with the material.
[0003] Currently used composite sand mill screens are prone to clogging during use. Some materials (such as high-viscosity slurries, materials containing fibers or flaky particles) are easily adsorbed onto the screen surface during grinding, forming a "filter cake layer" that gradually blocks the screen holes. Coarse particles or agglomerates in the material may get stuck in the screen holes, especially when the screen hole size is close to the particle diameter. Therefore, it is necessary to improve the composite sand mill screen anti-clogging device to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a composite sand mill screen anti-clogging device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite sand mill screen anti-clogging device, comprising an outer shell and a screen body, wherein the screen body is disposed inside the outer shell, a tapping mechanism is disposed inside the outer shell extending to the right side, and a cleaning mechanism is disposed inside the outer shell.
[0006] The beating mechanism includes a motor, which is fixedly installed on the right side of the outer casing. A rotating shaft is fixedly installed at the output end of the motor. A support and a bracket are fixedly installed inside the outer casing. A connecting block is fixedly installed outside the rotating shaft. A threaded column is fixedly installed outside the connecting block. A rubber strip is movably installed outside the threaded column. A pressure plate is sleeved on the outside of the threaded column. A positioning block is fixedly installed outside the pressure plate. A nut is installed on the external thread of the threaded column to facilitate beating the screen body and knocking off the solidified material.
[0007] Preferably, a through groove is provided at the corresponding position of the connecting block and the positioning block, and the positioning block is inserted into the through groove to facilitate the positioning and installation of the pressure plate.
[0008] Preferably, the end of the rotating shaft away from the motor is rotatably mounted on the outside of the support, and a through hole is provided at the corresponding position of the support and the rotating shaft, and the rotating shaft is rotatably mounted inside the through hole, so as to facilitate the support and rotation of the rotating shaft.
[0009] Preferably, multiple connecting blocks, threaded columns, rubber strips, positioning blocks, pressure plates, and nuts are provided and arranged in a circular and linear array outside the rotating shaft to facilitate the rubber strips to beat the screen body.
[0010] Preferably, the cleaning mechanism includes a fixed frame, which is fixedly installed inside the outer casing. A sliding block is slidably installed inside the fixed frame. A connecting slide rod is fixedly installed on the outer side of the sliding block. A cleaning roller brush is rotatably installed on the inner side of the connecting slide rod. A compression spring is fixedly installed between the outer side of the sliding block and the inner wall of the outer side of the fixed frame, so as to facilitate cleaning of the outer wall of the screen body by the cleaning roller brush.
[0011] Preferably, there are two of each of the fixed frame, sliding block, compression spring and connecting slide rod, and they are symmetrically arranged around the center line of the right side of the cleaning roller brush. The cleaning roller brush is rotatably installed between the two connecting slide rods, and the cleaning roller brush is in contact with the outer surface of the screen body, so that the cleaning roller brush can be pressed tightly against the outer wall of the screen body.
[0012] Preferably, a through hole is provided at the corresponding position of the fixed frame and the connecting slide rod, and the connecting slide rod passes through the through hole to facilitate the connecting slide rod to slide through the fixed frame.
[0013] Compared with the prior art, this utility model provides a composite sand mill screen anti-clogging device, which has the following beneficial effects:
[0014] 1. This composite sand mill screen anti-clogging device, through the set-in tapping mechanism, uses a motor-driven rotating shaft to rotate during use, causing the rotating shaft to drive the external rubber strips to rotate and tap. At the same time, in conjunction with the rotation of the screen body, the material that has solidified or is stuck inside the screen body falls off, thereby preventing the screen body from clogging during use. Furthermore, the detachable rubber strip structure makes it easy to replace the worn rubber strips.
[0015] 2. The anti-clogging device for the screen of this composite sand mill, through the cleaning mechanism, when the screen body rotates during use, its cleaning roller brush is pressed against the outside of the screen body, so that the screen body can rotate and clean. The brush bristles can not only clean the material clogging in the mesh of the screen body, but also prevent the material from clumping on the outside of the screen body. Attached Figure Description
