[0023] 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.

[0024] Example 1

[0025] The existing technology is not easy to circulate the pigment and affect the grinding effect. This embodiment provides a grinding device for low oil absorption iron oxide red pigment. Please refer to Figure 1-Figure 5 The device, which is used to grind low-oil-absorption iron oxide red pigment, can circulate and transport the pigment, improving the completeness of the pigment grinding, the grinding effect, and the product quality. The grinding device comprises a grinding box 2 mounted on top of a base frame 1. A grinding and screening mechanism 3 for grinding the pigment is provided within the grinding box 2. A circulating feeding mechanism 4 for automatically conveying the pigment is also provided on the grinding box 2. The grinding and screening mechanism 3 not only grinds the pigment in both directions but also screens the ground pigment, improving the pigment's production quality.

[0026] During the pigment grinding process, in order to fully grind the pigment multiple times and improve grinding efficiency, a circulating feeding mechanism 4 includes a storage box 41 installed on the side of the grinding box 2, a rotating motor 42 installed at the bottom of the storage box 41, a feeding barrel 43 installed at the top of the storage box 41, and a feeding roller 44 connected to the output end of the rotating motor 42. A baffle 45 is installed inside the top of the grinding box 2. The baffle 45 is distributed just below the top of the feeding barrel 43 to facilitate better conveying of the ground pigment. The baffle 45 is distributed at an oblique angle at the top of the grinding box 2, so that the pigment can be accurately guided to the grinding area to improve grinding efficiency. The grinding box 2 is provided with a drying component 401 for heating the pigment. Under the connection of the sieve plate 312, unqualified pigment rolls into the storage box 41. The operation of the rotating motor 42 drives the feeding roller 44 to rotate, thereby conveying the pigment through the feeding barrel 43 to the top of the grinding box 2. Under the load of the baffle 45, the pigment is ground again, thus achieving the effect of circulating grinding.

[0027] During the pigment grinding process, to eliminate water molecules inside the grinding box 2 and prevent the pigment from clumping, the drying assembly 401 includes an electric heater 46 mounted on the grinding box 2. The output end of the electric heater 46 is connected to a heat pipe 47, the other end of which is mounted to a heat-conducting nozzle 48 connected to the inside of the grinding box 2. Heat generated by the operation of the electric heater 46 is transferred through the heat pipe 47 to the heat-conducting nozzle 48, thereby transferring the heat to the interior of the grinding box 2, thereby improving the production quality of the pigment.

[0028] Example 2

[0029] On the basis of Example 1, Figure 1-Figure 5 As shown, based on the problem that it is not easy to circulate the pigment in the existing technology, which affects the grinding effect, but in the process of grinding the pigment, it is not easy to screen the ground pigment, which easily reduces the production quality of the pigment, therefore, the device is also provided with a structure for screening the pigment.

[0030] To improve the quality of pigment grinding during pigment grinding, the grinding and screening mechanism 3 includes a drive motor 1 31 mounted on the side of the grinding box 2. The output end of drive motor 1 31 is connected to a grinding roller 1 32. A drive motor 2 33 is mounted on the grinding box 2. The output end of drive motor 2 33 is connected to a grinding roller 2 34. A rotating disk 35 is mounted on the output end of drive motor 2 33. A connecting belt 36 is connected to the connection between rotating disk 35 and the grinding box 2. A screening mechanism 301 for screening pigment is provided within the grinding box 2. The operation of drive motor 1 31 drives grinding roller 1 32 to rotate in one direction, while the operation of drive motor 2 33 causes grinding roller 2 34 to rotate in the other direction, thereby fully grinding the pigment.

[0031] In the production process of the pigment, in order to produce the pigment with better quality, the screening mechanism 301 comprises a rotating rod 37 rotatably connected in the grinding box 2, the rotating rod 37 is provided with a connecting disc 38 connected with the connecting belt 36, the rotating rod 37 is provided with two groups of vibrating pieces 39, the grinding box 2 is internally provided with a limiting piece 310, the limiting piece 310 is connected with a buffer spring 311, the top end of the buffer spring 311 is connected with a sieve plate 312 in sliding connection with the limiting piece 310, the sieve plate 312 is distributed at an inclined angle in the grinding box 2, so that the pigment not meeting the requirements can fall into the storage box 41, the bottom end of the sieve plate 312 is provided with two groups of pads 313, the positions of the pads 313 correspond to the positions of the vibrating pieces 39, so that the sieve plate 312 can be better vibrated. The pigment after primary grinding falls on the sieve plate 312, under the buffering effect of the buffer spring 311, the pressure of the pigment on the sieve plate 312 can be reduced, the pigment not meeting the requirements falls into the storage box 41, so that the grinding can be recycled, and under the operation of the driving motor two 33, the rotating disc 35 can be driven to rotate, under the action of the connecting belt 36 and the connecting disc 38, the rotating rod 37 can be driven to rotate, so that the vibrating pieces 39 continuously hit the pads 313, so that the sieve plate 312 is vibrated, the sieve hole is prevented from being blocked by the pigment, and the screening efficiency is improved.
