[0002] Disperse dyes are a type of dye with relatively small molecules and no water-soluble groups in their structure. When dyeing, it must be dispersed evenly in the dye liquor with the help of a dispersant in order to dye fibers such as polyester. In the commodity processing of disperse dyes, in order to make the commodity dyes disperse quickly in water into a uniform and stable colloidal suspension, the fineness of the dye particles must reach about 1 micron, and a sand mill is required for the grinding process. Sand mills, also known as bead mills, are mainly used for wet grinding of chemical liquid products. They are mainly composed of a machine body, a grinding cylinder, a sanding disc (paddle), a grinding medium, a motor and a feed pump. The grinding medium is mainly glass beads, zirconium oxide beads, etc.

[0007] By adopting the above technical scheme, a frame, a grinding cylinder, a driving motor, a rotating shaft, a filter mesh tube, a blocking ring, a rotating arm, a cleaning mechanism, and a connecting mechanism are provided. The disperse dye enters the grinding cylinder through the feed pipe. The grinding cylinder is filled with grinding media. The driving motor drives the rotating shaft to rotate, which drives the lever to rotate, so that the grinding media rub and collide with each other in the grinding cylinder to grind the disperse dye. The disperse dye that meets the requirements can pass through the filter mesh tube and then enter the discharge pipe to be discharged. After long-term use, larger raw material particles of the disperse dye are likely to block the mesh of the filter mesh tube, reducing the filtering efficiency of the filter mesh tube. The rotating block is connected to the rotating shaft through the connecting mechanism. When the rotating shaft rotates, the rotating block is driven to rotate, thereby driving the rotating arm and the cleaning mechanism to rotate, so that the cleaning mechanism cleans the filter mesh tube to ensure the filtering efficiency of the filter mesh tube. The distance between two adjacent blocking rings is set to be smaller than the diameter of the grinding media, so that the grinding media cannot directly impact the filter mesh tube, thereby protecting the filter mesh tube and preventing the filter mesh tube from being deformed and damaged and unable to filter.

[0008] Furthermore, the cleaning mechanism comprises a brush plate vertically arranged on the rotating arm, and the bristle part of the brush plate abuts against the outer tube wall of the filter screen tube.

[0009] By adopting the above technical solution, the connecting mechanism connects the rotating block with the rotating shaft. When the rotating shaft rotates, it drives the rotating block and the rotating arm to rotate, so that the brush plate rotates around the filter mesh tube. The bristle part of the brush plate abuts against the outer tube wall of the filter mesh tube to clean the filter mesh tube, thereby ensuring the filtration efficiency of the filter mesh tube.

The connecting column is pushed up by the adjusting mechanism to make the connecting plate and the vertical teeth rise, so that the vertical teeth slide into the connecting groove and cooperate with the connecting groove, so that when the rotating shaft drives the connecting seat to rotate, the connecting plate and the connecting column are driven to rotate, and the connecting column and the connecting tube are circumferentially limited by the sliding block and the sliding groove. When the connecting column rotates, it drives the connecting tube to rotate, thereby driving the rotating block to rotate.

[0014] Furthermore, a protection tube is vertically arranged at the bottom of the connection seat, and the inner diameter of the protection tube is consistent with the outer diameter of the connection tube.

[0015] By adopting the above technical solution, a protective tube is vertically arranged at the bottom of the connecting seat, so as to prevent the grinding medium from entering the connecting groove when the vertical tooth is not inserted into the connecting groove, so that the vertical tooth cannot be inserted into the connecting groove when it needs to be inserted.

[0016] Furthermore, the tooth surface of the vertical tooth located in the rotation direction of the rotating shaft is an inclined surface, and the other tooth surface is a vertical surface.

[0017] By adopting the above technical solution, the tooth surface of the vertical tooth located in the rotation direction of the rotating shaft is set as an inclined surface, and the other tooth surface is set as a vertical surface. One tooth surface is an inclined surface, which is convenient for the vertical tooth to slide into the connecting groove when it rises, and the other tooth surface is a vertical surface. When the rotating shaft rotates and drives the connecting seat to rotate, the groove wall of the connecting groove pushes the vertical surface of the vertical tooth, making the transmission more stable.

The second magnet is driven to rise by pushing the adjusting rod upward. The upper part of the second magnet has the same polarity as the lower part of the first magnet, so that the first magnet is pushed upward, thereby driving the connecting column to rise.

[0020] Furthermore, an adjusting hole is horizontally opened on the adjusting tube, a threaded rod is spirally arranged in the adjusting hole, one end of the threaded rod is in contact with the adjusting rod, and a screwing handle is arranged at the other end.

[0021] By adopting the above technical solution, an adjustment hole, a threaded rod, and a screw handle are set. The screw handle is turned to drive the threaded rod to rotate, so that the end of the threaded rod abuts or separates from the adjustment rod. When abutting, the position of the adjustment rod is fixed, and when separated, the adjustment rod can be adjusted.

[0022] In summary, the utility model has the following beneficial effects: in the present application, a frame, a grinding cylinder, a driving motor, a rotating shaft, a filter mesh tube, a blocking ring, a rotating arm, a cleaning mechanism, and a connecting mechanism are provided. The disperse dye enters the grinding cylinder through a feed pipe. The grinding cylinder is filled with a grinding medium. The driving motor drives the rotating shaft to rotate, and drives the lever to rotate, so that the grinding medium rubs and collides with each other in the grinding cylinder to grind the disperse dye. The disperse dye that meets the requirements can pass through the filter mesh tube and then enter the discharge pipe to be discharged. After long-term use, larger raw material particles of the disperse dye are likely to clog the mesh of the filter mesh tube, thereby reducing the filtering efficiency of the filter mesh tube. The rotating block is connected to the rotating shaft through a connecting mechanism. When the rotating shaft rotates, the rotating block is driven to rotate, thereby driving the rotating arm and the cleaning mechanism to rotate, so that the cleaning mechanism cleans the filter mesh tube to ensure the filtering efficiency of the filter mesh tube. The distance between two adjacent blocking rings is set to be smaller than the diameter of the grinding medium, so that the grinding medium cannot directly impact the filter mesh tube, thereby protecting the filter mesh tube and preventing the filter mesh tube from being deformed and damaged and unable to filter.
