Description

Technical Field

[0001] This utility model belongs to the technical field of water-reducing agent processing equipment, and in particular relates to a raw material grinding device for water-reducing agent production. Background Technology

[0002] Water-reducing agents are concrete admixtures that reduce the amount of water used in mixing while maintaining a relatively constant slump. Most are anionic surfactants, including lignin sulfonates, naphthalene sulfonates, and formaldehyde polymers. When added to concrete mixes, they disperse cement particles, improve workability, reduce water consumption per unit area, improve the fluidity of the concrete mix, or reduce the amount of cement used per unit area. Water-reducing agents are available in liquid and powder forms.

[0003] In the production process of water-reducing agents, the raw materials for the water-reducing agent need to be ground to a certain particle size. Therefore, a grinding device is required. The grinding device grinds coarse particles into fine particles that meet the standards, which are then used to mix with other raw materials / additives to prepare the final water-reducing agent product. Most existing grinding devices use grinding rollers or grinding discs to continuously crush and grind the particles accumulated in the grinding chamber.

[0004] However, existing grinding equipment suffers from poor material transport between different processes during grinding. That is, after crushing, the material cannot be efficiently and thoroughly transferred to the grinding process, resulting in a long overall grinding time and incomplete grinding effect. Therefore, there is an urgent need to design a raw material grinding device for water-reducing agent production to solve the above problems. Utility Model Content

[0007] The advantages and positive effects of this utility model are as follows: This utility model provides a raw material grinding device for water-reducing agent production.

[0031] Working principle:

[0032] In actual operation, the drive motor 3 can synchronously drive the crushing component 9 and the grinding component 13 to work, and feed the material to be crushed into the feed hopper 8. The rotating crushing screw 9-3 and the spiral blade 9-2 can drive the material to move along the crushing outer cylinder 9-1 toward the discharge port. Since the outer diameter of the crushing screw 9-3 gradually increases from the feed port to the discharge port, the material can be crushed to a certain extent during forward transmission. Since there are several crushing protrusions 9-5 between the outer wall of the crushing cylinder 9-4 and the inner wall of the crushing outer cylinder 9-1, when the material is transmitted between the crushing cylinder 9-4 and the crushing outer cylinder 9-1, the rotating crushing cylinder 9-4 can perform a second crushing operation on the material.

[0033] The material that has completed the crushing operation is discharged from the discharge plate 9-7 through several discharge holes 9-6 into the discharge pipe 12, and then introduced into the grinding assembly 13 for grinding. During this process, the linear drive 11-4 drives the disturbance head 11-1 to move back and forth, which can disturb the material at the discharge port of the discharge pipe 12 to avoid material blockage affecting the normal operation of the grinding device. In the grinding assembly 13, the rotating grinding disc mechanism 2 13-8 cooperates with the grinding disc mechanism 13-7 to grind the material that has completed the crushing operation.
