Description

Technical Field

[0001] This utility model relates to the technical field of sand grinding equipment, specifically a disc with a pin. Background Technology

[0002] Sand mills are common grinding equipment in industrial production. Currently, there are many structural forms of wet grinding discs commonly used. The main structural forms of grinding discs on the market include discs with holes on the disc surface, discs with smooth surfaces, and discs with various through-grooves. The grinding discs disclosed in the prior art each have their own characteristics, but there is still room for improvement in terms of high-efficiency grinding, energy consumption reduction, grinding disc strength, crack resistance, and service life.

[0003] To address the aforementioned issues, the utility model patent with authorization announcement number CN201807408U discloses a grinding disc for a sand mill. This grinding disc enhances the friction and shearing between the grinding media and the particles of the material being ground, thereby improving the sand milling efficiency. It can be widely used in high-efficiency grinding equipment in industries such as paint, dyes, and inks.

[0004] However, in actual use, grinding is limited by the shearing force of the disc alone, and it usually takes a longer time to complete the grinding work, which cannot well meet the needs of use. Utility Model Content

[0005] The purpose of this invention is to provide a disc with a pin to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A disc with pins includes: a disc on which multiple sets of pin assemblies are detachably mounted; each pin assembly includes a pin body, a positioning block at the upper end of the pin body, a connecting screw at the upper end of the positioning block, an installation hole on the disc, a positioning groove at the lower end of the disc corresponding to the installation hole, the positioning block being inserted into the positioning groove, and a connecting nut being threaded onto the end of the connecting screw through the installation hole.

[0008] As a preferred embodiment, the positioning block is hexagonal prism-shaped, and the positioning groove is adapted to the positioning block.

[0009] As a preferred embodiment, the disk and pin assembly are made of cemented carbide.

[0010] As a preferred embodiment, a connecting seat is also installed in the middle of the disc, and the connecting seat is fixedly connected to the grinding rotating shaft by bolts.

[0011] As a preferred embodiment, the connecting seat is further provided with a limiting groove, and the grinding rotating shaft is integrally formed with a limiting protrusion, which is inserted into the limiting groove.

[0012] As a preferred embodiment, the disk is also provided with multiple sets of material discharge ports.

[0013] As a preferred embodiment, the disk is further provided with a number of distributed grooves.

[0014] As a preferred embodiment, the dispersion trough is located outside the material discharge port.

[0015] Compared with existing technologies, the beneficial effects of this invention are: by using the pin body to move the raw material and the grinding ball, the probability of collision between the raw material and the grinding ball is increased, thereby improving the grinding effect, accelerating the grinding speed, and thus better meeting the usage requirements. This invention has a reasonable structure and can effectively improve the grinding effect and efficiency, thereby better meeting the usage requirements. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Please refer to Figures 1-6 A disc with pins includes: a disc 2, on which multiple sets of pin assemblies 3 are detachably mounted; each pin assembly 3 includes a pin body 31, a positioning block 32 is provided at the upper end of the pin body 31, a connecting screw 33 is installed at the upper end of the positioning block 32, the disc 2 has an installation hole 35, the lower end of the disc 2 has a positioning groove 36 corresponding to the position of the installation hole 35, the positioning block 32 is inserted into the positioning groove 36, the end of the connecting screw 33 passes through the installation hole 35 and is threaded with a connecting nut 34, and multiple sets of material discharge ports 22 are also distributed on the disc 2.

[0025] The working principle of this utility model is as follows: During installation, the connecting screw 33 is passed through the mounting hole 35 and the positioning block 32 is inserted into the positioning groove 36. Then, the connecting nut 34 is screwed onto the end of the connecting screw 33 to complete the installation of the pin assembly 3.

[0026] During operation, the raw material falls through the feed inlet. The pin body 31 moves the raw material and the grinding ball, increasing the probability of collision between the raw material and the grinding ball, thereby improving the grinding effect, speeding up the grinding process, and better meeting the usage requirements.

[0027] As a further solution, the positioning block 32 is hexagonal prism-shaped, and the positioning groove 36 is adapted to the positioning block 32. By setting the positioning block 32 to cooperate with the positioning groove 36, the possibility of the pin body 31 rotating can be reduced.

[0028] As a further improvement, the disk 2 and the pin assembly 3 are made of cemented carbide. By using cemented carbide for the disk 2 and the pin assembly 3, the strength of the device can be effectively improved, thereby extending its service life.

[0029] As a further solution, a connecting seat 21 is also installed at the middle position of the disc 2, and the connecting seat 21 is fixedly connected to the grinding rotating shaft 1 by bolts. By setting the connecting seat 21, it is convenient to fix the disc 2 on the grinding rotating shaft 1.

[0030] As a further solution, a limiting groove 111 is also provided on the connecting seat 21, and a limiting protrusion 11 is integrally formed on the grinding rotating shaft 1, the limiting protrusion 11 being inserted into the limiting groove 111. By setting the limiting groove 111 in conjunction with the limiting protrusion 11, the rotation of the disc 2 relative to the grinding rotating shaft 1 can be effectively prevented.

[0031] As a further improvement, the disc 2 is further provided with a plurality of dispersion grooves 23, which are located outside the material inlet 22. By providing dispersion grooves 23, when the disc 2 rotates, the raw material in the dispersion grooves 23 can be thrown out, which can increase the probability of the raw material colliding with the grinding balls and improve the grinding efficiency.

[0032] In this utility model, terms such as "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "side", and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only used to facilitate the description of the structural relationship between the various components or elements of this utility model and do not specifically refer to any component or element in this utility model. They should not be construed as limiting this utility model.
