Description

Technical Field

[0001] This utility model relates to the field of carbon black technology, specifically to a grinding mill for carbon black processing. Background Technology

[0002] Carbon black is a quasi-graphite structured substance composed of colloidal particles that are approximately spherical, formed from hydrocarbon compounds (mainly petroleum derivatives) through incomplete combustion or thermal decomposition. It exists in aggregate form and appears as a pure black powder or granules.

[0003] Utility model patent CN221108495U discloses a raw material grinding mill for carbon black production. It solves the problem of limited grinding precision and insufficient smoothness in current grinding mills, which affects subsequent processing. The mill employs an electric push rod, filter plates, a first linkage shaft, a second linkage shaft, a filter base, and grinding plates. Two sets of filter plates move relative to each other using the electric push rod, initially grinding the raw material accumulated on the filter plate surface. After grinding to a certain extent, the material passes through the filter plate and is driven to rotate. The meshing relationship between the first and second right-angle gears drives the second linkage shaft to rotate, and the rotating grinding plate performs secondary grinding on the raw material on the filter base surface, improving the equipment's working efficiency. The grinding precision can be improved by utilizing the filter holes on the filter plates and filter base surface, ensuring thorough grinding. While the structure is simple, in actual use, the method of grinding the raw material on the top of the filter plates using two sets of filter plates moving relative to each other with the electric push rod results in low grinding efficiency. Furthermore, during grinding, some raw material easily rolls out of the filter plate, leaving some unground material and thus leading to poor grinding results. Utility Model Content

A third motor 11 is fixedly connected to the right side of the inner wall of the grinding box 1 via a bracket. A grinding frame 12 is fixedly connected to the output end of the third motor 11. The grinding frame 12 is in contact with the filter frame 10. A motor protective box is fixedly connected to the surface of the third motor 11.

[0021] refer to Figure 1 and Figure 2 The metering component 3 includes a metering cylinder 13 fixedly connected to the top of the crushing box 2. A metering wheel 14 is movably connected inside the metering cylinder 13. A fourth motor is fixedly connected to the back of the metering cylinder 13.

A feed hopper 15 is connected to the top of the metering cylinder 13.

[0022] As a technical optimization of this utility model, by setting the quantitative component 3, the operator puts the material to be ground into the feed hopper 15, and then the operator starts the fourth motor to rotate, which in turn drives the quantitative wheel 14 to rotate, so that the material in the feed hopper 15 can fall into the crushing box 2 at a uniform speed.

[0023] refer to Figure 1 and Figure 2A base plate 16 is provided below the grinding box 1. The base plate 16 is fixedly connected to the grinding box 1 by a support column. Limiting grooves are provided on the left and right sides of the front of the base plate 16, and sliding strips 17 are movably connected inside the limiting grooves. A collection box 18 is fixedly connected to the top of the sliding strip 17. A handle is fixedly connected to the front of the collection box 18. The collection box 18 is located below the opening.

[0024] As a technical optimization of this utility model, the collection box 18 can collect the material filtered out by the filter frame 10 through the setting of the base plate 16, the limiting groove, the sliding bar 17 and the collection box 18. Through the setting of the limiting groove and the sliding bar 17, when the operator needs to install the collection box 18, the operator aligns the sliding bar 17 with the limiting groove, thereby facilitating the installation of the collection box 18 in the accurate position.

[0025] refer to Figure 1 and Figure 2 The bottom of the base plate 16 is fixedly connected to the four sides of the cylinder 19. The cylinder 19 is threadedly connected to the threaded rod 20. The bottom of the threaded rod 20 is fixedly connected to the support pad 21.

[0026] As a technical optimization of this utility model, by setting up the cylinder 19, the threaded rod 20 and the support pad 21, the operator can rotate the threaded rod 20, thereby driving the support pad 21 to move up or down, and thus adjust the horizontal state of the base plate 16.

[0027] refer to Figure 1 The front of the grinding box 1 is provided with a sealing plate 22, and the surface of the sealing plate 22 is movably connected with a bolt 23. The bolt 23 is threadedly connected to the grinding box 1, and the surface of the bolt 23 is sprayed with anti-rust paint. The back of the sealing plate 22 is respectively attached to the guide plate 8 and the grinding block 7.

[0028] As a technical optimization of this utility model, by setting the sealing plate 22 and the bolt 23, the operator can use a tool to tighten the bolt 23, thereby installing the sealing plate 22, and the sealing plate 22 can seal the front of the grinding box 1.

[0029] refer to Figure 1 An observation window 24 is provided on the front of the sealing plate 22, and the observation window 24 is made of tempered glass.

[0030] As a technical optimization of this utility model, the setting of the observation window 24 makes it easy for the operator to observe the grinding state of the material in the grinding box 1 through the sealing plate 22.

[0031] The working principle and usage process of this utility model are as follows: During use, the material in the feed hopper 15 falls uniformly into the crushing box 2. Then, the operator starts the first motor 5 to rotate, driving the crushing rods 4 to rotate. The two crushing rods 4 rotate in opposite directions, thus pre-crushing the material. The pre-crushed material falls into the grinding box 1 and is then guided to the surface of the grinding blocks 7 by the guide plate 8. The operator then starts the second motor to rotate, driving the grinding rollers 6 to rotate clockwise, thus grinding the material. The ground material falls through the guide frame 9 to the bottom of the inner wall of the filter frame 10. The properly ground material passes through the through-hole and falls into the collection box 18. Part of the ground material... Unqualified materials accumulate at the bottom of the inner wall of the filter frame 10. At this time, the operator can start the third motor 11 to rotate and drive the grinding frame 12 to rotate. The grinding frame 12 includes a rotating shaft and rotating blades. There are several rotating blades, which are evenly distributed in a ring on the surface of the rotating shaft. The rotating blades are inclined. From a top view, the grinding frame 12 rotates counterclockwise. When the rotating blades rotate, they will apply a downward force to the material, which will cooperate with the filter frame 10 to crush the unqualified material, so that the material can pass through the through hole. At the same time, when the grinding frame 12 rotates, it can also prevent the filter frame 10 from clogging.
