Description

Technical Field

[0001] This utility model belongs to the technical field of grinding equipment, and relates to a grinding wheel mill. Background Technology

[0002] A grinding wheel mill is a common piece of equipment used to grind materials into slurry (such as soy milk or starch slurry). It consists of a grinding wheel assembly composed of a stationary grinding wheel and a moving grinding wheel. During grinding, the moving grinding wheel is driven by a power unit to rotate relative to the stationary grinding wheel to grind the material.

[0003] When grinding different specifications of slurry, different specifications of grinding wheel components are required. However, the gap between the stationary and moving grinding wheels of existing grinding wheel mills is difficult to adjust, and each mill can only produce one specification of slurry.

[0004] Chinese utility model patent CN210994528U (publication date: 2020-07-14) discloses a grinding wheel gap adjustment device for a pulp refiner, including an adjusting nut and a machine cover. During rotation of the adjusting nut, the nut can drive the stationary grinding wheel downwards, thereby reducing the gap between the stationary and moving grinding wheels. However, this pulp refiner cannot finely adjust the grinding wheel gap; it can only prevent excessive gaps or wheel jamming, and cannot be used for adjusting the gap between different specifications of pulp. Utility Model Content

The bottom of the outer circumference of the upper grinding wheel seat 6 is screwed to the grinding cylinder 1, and a circumferential gear ring 7 is disposed on its top. The gear ring 7 meshes with an adjusting gear 8 driven by an adjusting power device. The wheel seat 6 and the upper grinding wheel 4 generate axial displacement as the gear ring 7 rotates; in this embodiment, the adjusting power device includes an adjusting seat 11 disposed on one side of the grinding cylinder 1, an adjusting gear shaft 12 is rotatably disposed inside the adjusting seat 11, and the adjusting gear 8 is fitted on the adjusting gear shaft 12, and the adjusting seat 11 and the grinding cylinder 1 are provided with openings to avoid the gear ring 7 and the adjusting gear 8; furthermore, the upper end of the adjusting gear shaft 12 extends out of the adjusting seat 11 and is connected to an adjusting handwheel 13, and the adjusting handwheel 13 drives the adjusting gear shaft 12 to rotate.

The adjustment gear 8, mounted on the adjustment gear shaft 12, drives the meshing gear ring 7 to rotate, which in turn drives the upper grinding wheel seat 6 and the upper grinding wheel 4 to rotate together. When the upper grinding wheel seat 6 rotates relative to the grinding cylinder 1, it generates axial displacement, which in turn drives the upper grinding wheel 4 to generate axial displacement, thereby changing the gap between the upper grinding wheel 4 and the lower grinding wheel 5. After adjustment to the required specifications, the material to be ground is poured in through the feed inlet 2. The material enters between the upper grinding wheel 4 and the lower grinding wheel 5. The grinding power device drives the lower grinding wheel 5 to rotate relative to the upper grinding wheel 4, thereby grinding the material.

[0028] The upper grinding wheel 4 and the lower grinding wheel 5 form a feeding chamber 14 that communicates with the feed inlet 2. The grinding wheel assembly and the grinding cylinder 1 form a discharge chamber 15 that communicates with the discharge outlet 3. The bottom of the discharge chamber 15 is provided with a guide slope to guide the material to the discharge outlet 3.
