[0002] Sand mills, also known as bead mills, are primarily used for wet grinding of liquid chemical products. Turbine sand mills use a main shaft to drive a dispersing turbine at high speed, stirring the grinding media within the barrel, creating swirl and radial-axial motion. This forcibly grinds and disperses the product, achieving the desired fineness and color saturation. Turbine sand mills are often used in the production of paints and coatings.

[0003] The explosion-proof turbine sand grinder for paint and coatings disclosed in Chinese patent CN213408872U has a grinding assembly fixedly installed inside the cylinder, and the discharge pipe assembly also includes a fixed discharge pipe, a movable discharge pipe and a pressing disc. The grinding assembly also includes a main shaft and a filter cleaning component. A gap filter is fixedly installed on the outer surface of one end of the main shaft. The discharge pipe assembly is used to clean and remove the raw materials solidified inside the fixed discharge pipe during discharge, and the filter cleaning component is used to automatically clean the gap filter when the main shaft rotates.

[0004] This sand mill uses a grinding disc for grinding. The ground material is filtered through a gap filter before entering the discharge box. If the filter is clogged, use a cylindrical brush or strip brush to remove particles from the filter surface. However, particles clogged within the filter pores are difficult to remove, resulting in inadequate cleaning results.

[0005] In order to solve the above problems, the utility model proposes an explosion-proof turbine sand grinder for paint and coatings. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figures 1-4 As shown, the technical solution adopted by the utility model is as follows: an explosion-proof turbine-type paint and coating sand grinder includes a base plate 1, and a discharge box 2 is fixedly arranged above the base plate 1. The bottom of the discharge box 2 is fixedly connected to a support column, and the bottom end of the support column is fixedly connected to the upper surface of the base plate 1.

[0026] One side of the discharge box 2 is fixedly connected with a cylinder 16. A through hole is provided on the side of the discharge box 2 at the cylinder 16, and a filter screen 11 is fixedly connected inside the through hole. The inner cavity of the discharge box 2 is communicated with the inner cavity of the cylinder 16 through the through hole.

[0027] The interior of the cylinder 16 is rotatably connected to a connecting rod 4. The connecting rod 4 is arranged horizontally.

[0028] One end of the top of base plate 1 is fixedly connected to a support frame, and the top of the support frame is fixedly connected to motor 3. One end of connecting rod 4 is rotatably connected to the inner wall of cylinder 16 at the end away from discharge box 2. The other end of connecting rod 4 rotates through filter screen 11 and discharge box 2 in sequence. The other end of connecting rod 4 is fixedly connected to the output shaft of motor 3.

[0029] A plurality of grinding discs 7 are fixedly sleeved on the connecting rod 4 at intervals, and the grinding discs 7 are all located inside the cylinder 16. A cylinder 8 is rotatably connected to the outer surface of the connecting rod 4 near the filter screen 11, and the cylinder 8 rotates on the side of the filter screen 11.

[0030] There are two cylinders 8, which are distributed in a circumferential array about the connecting rod 4. The ends of the two cylinders 8 are both rotatably connected to the outer surface of the connecting rod 4.

[0031] The discharge box 2 is provided with a transmission assembly, which cooperates with the connecting rod 4. When the connecting rod 4 rotates, the transmission assembly drives the cylinder 8 to rotate.

[0032] The transmission assembly includes a gear ring 10, which is fixedly connected to the outer surface of the discharge box 2. The gear ring 10 is located inside the cylinder 16, and the gear ring 10 is coaxially arranged with the through hole.

[0033] The ends of the two cylinders 8 away from the connecting rod 4 are fixedly connected to gears 9 , and the gears 9 are meshed with the gear ring 10 .

[0034] Several protrusions 12 are evenly and fixedly connected to the outer surface of the cylinder 8. The protrusions 12 engage with the filter holes of the filter screen 11. When the cylinder 8 rotates on one side of the filter screen 11, the protrusions 12 squeeze the particulate material in the filter holes of the filter screen 11, pushing the particulate material out of the filter holes, achieving the purpose of cleaning and reducing clogging.

[0035] A discharge tube 5 is fixedly inserted through the bottom of the discharge box 2. A threaded plug 6 is threadedly connected to the inside of the discharge tube 5. The plug 6 is screwed into the discharge tube 5 to seal it. Several ejector pins are evenly fixed to the top of the plug 6. When the plug 6 is screwed into the discharge tube 5, it rotates the ejector pins, causing them to stir the material at the top of the discharge tube 5, facilitating discharge.

[0036] An annular cooling groove is provided on the side of the cylinder 16 . A cooling pipe 15 is spirally wound inside the cooling groove. Both ends of the cooling pipe 15 are fixedly passed through the side of the cylinder 16 .

[0037] One side of the cylinder 16 is fixedly connected to the water tank 13, and one side of the water tank 13 is fixedly connected to the water pump 14. One end of a cooling pipe 15 extends into the water tank 13, and the other end of the cooling pipe 15 is fixedly connected to the output end of the water pump 14. The input end of the water pump 14 extends into the water tank 13. The water in the water tank 13 is conveniently drained into the cooling pipe 15 via the water pump 14. A water cooler is installed on the water tank 13 to cool the water in the water tank 13.

[0038] The top of one end of the cylinder 16 is fixedly connected with a feed port 17. The feed port 17 is tilted upward away from one end of the cylinder 16.

[0039] Working principle:

[0040] When in use, the paint material is passed into the interior of the barrel 16 through the feed port 17. The motor 3 is started, and the output shaft of the motor 3 drives the connecting rod 4 to rotate.

[0041] The connecting rod 4 drives a plurality of grinding discs 7 to rotate, and the grinding discs 7 grind the material. The ground material is filtered through a filter screen 11 and then enters the interior of the discharge box 2.

[0042] Connecting rod 4 similarly drives cylinder 8 and gear 9 to rotate about its axis of rotation, causing gear 9 to rotate on ring gear 10. Ring gear 10 drives gear 9 to rotate, causing cylinder 8 to rotate. As cylinder 8 pushes particulate material against one side of filter screen 11, bumps 12 squeeze the particulate material within the pores of filter screen 11, pushing it out. This reduces accumulation of particulate material within the pores and ensures more thorough cleaning.

[0043] During the grinding process, the water pump 14 is started to pass the cold water in the water tank 13 into the cooling pipe 15 to cool the cylinder 16. The cooled water returns to the water tank 13 again.

[0044] When the material in the discharge box 2 needs to be discharged, the threaded plug 6 is rotated, and the threaded plug 6 is rotated and moved downward in the discharge pipe 5. Until the threaded plug 6 is moved out, the material can be discharged from the discharge pipe 5.

[0045] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
