[0027] Example 1:

[0028] like Figure 1-5As shown, this utility model provides an efficient grinding and dispersing device for organic pigments, including a housing 1 and a feeding chamber 2. The housing 1 is equipped with a dispersing plate 6 and a grinding plate 8, and has a discharge port 13 on the lower part of its outer wall. The feeding chamber 2 is connected to the housing 1, and has a motor 3, a first feeding port 201 and a second feeding port 202 on its top. It also includes a reflux pipe 14 and a pump body 1401. One end of the reflux pipe 14 is connected to one side of the discharge port 13, and the other end is connected to the second feeding port 202. The pump body 1401 is installed on the reflux pipe 14. The design of the reflux pipe 14 and the pump body 1401 forms a reflux system, which allows the coarse particles that have not been sufficiently ground in the discharge port to be recycled and ground again, thereby maximizing the utilization of raw materials and greatly reducing costs.

[0029] In this embodiment, a screen 1301 is installed at an incline inside the discharge port 13. A flange 15 is installed on one side of the discharge port 13 between the screen 1301 and the housing 1. A return pipe 14 is installed on the other end of the flange 15, so that qualified particles are produced through the discharge port 13, and unqualified particles enter the return pipe through the flange 15 and the pump body 1401 for secondary grinding.

[0030] In this embodiment, the output end of the motor 3 is connected to a rotating rod 4, and a stirring paddle 5 is provided on the surface of the rotating rod 4 inside the feed chamber 2, which can initially break up large clumps of raw materials.

[0031] In this embodiment, a guide plate 104 is provided below the stirring paddle 5. The edge of the guide plate 104 is fixedly connected to the inner wall of the feed chamber 2, which can concentrate the raw materials into the lower dispersing plate 6 and avoid waste of raw materials.

[0032] In this embodiment, a bottom plate 9 is provided at the bottom of the box 1. The bottom plate 9 is located below the grinding plate 8. A small gap is left between the bottom plate 9 and the grinding plate 8 and several grinding balls 10 are installed there. Several fan-shaped strips 801 are provided at the bottom of the grinding plate 8. The grinding balls 10 can increase the friction and extrusion force during grinding. Together with the fan-shaped strips 801 and the bottom plate, the pigment particles can be refined.

[0033] In this embodiment, the upper part of the grinding plate 8 is fixedly connected to the collecting plate 7 via the support plate 12. The collecting plate 7 and the grinding plate 8 are tapered slopes with opposite inclination directions, and both have through holes in the middle. The collecting plate 7 and the grinding plate 8 are fixedly connected to the rotating rod 4 via the connecting rod 11. The tapered slope design is beneficial for raw material transportation and speeds up efficiency.

[0034] In this embodiment, the dispersing plate 6 is a conical inclined surface, and its center is fixedly connected to the rotating rod 4 and located above the collecting plate 7. The dispersing plate 6 can evenly disperse and sprinkle the raw materials onto the collecting plate 7 below.

[0035] In this embodiment, heat dissipation vents 102 are symmetrically distributed inside the lower outer shell of the housing 1. A fan 103 is installed inside the heat dissipation vents 102. A large amount of heat is generated when grinding raw materials. The heat dissipation vents 102 and the fan 103 dissipate heat from the housing 1 to avoid high temperature damage to the equipment.

[0036] In this embodiment, a placement plate 201 is installed below the motor 3. The placement plate 201 is fixedly connected to the feeding chamber 2. The placement plate 203 is used to fix the motor 3 to ensure stability.

[0037] The working principle of this utility model is as follows: the raw material enters the feeding chamber 2 from the first inlet 201. The motor 3 drives the rotating rod 4 to drive the stirring paddle 5 to stir, so that the raw material is initially dispersed. Then, it is guided to the dispersing plate 6 by the guide plate 104. The dispersing plate 6 is a conical inclined surface. With the rotation of the rotating rod 4, it evenly disperses the raw material and throws it onto the collecting plate 7 below. Since the collecting plate 7 is a conical inclined surface, it can gather the dispersed raw material to the central through hole and fall into the fan-shaped strip 801 at the bottom of the grinding plate 8. Through the connecting rod 11, it rotates with the rotating rod 4. The pigment particles are refined by the squeezing and collision of the grinding balls 10, the fan-shaped strip 801 and the bottom plate 9. The ground particles are discharged from the outlet 13 and screened by the internal inclined screen 1301. The qualified fine particles are directly output, and the coarse particles enter the return pipe 14 through the flange 15 and are transported to the second inlet 202 by the pump body 1401 to re-enter the feeding chamber 2 for secondary grinding.

[0038] The design of the return pipe 14 and the pump body 1401 forms a return system, which allows the coarse particles that have not been sufficiently ground in the discharge port 13 to be recycled and ground again, thereby maximizing the utilization of raw materials and greatly reducing costs.
