Description

Technical Field

[0001] This utility model belongs to the field of chemical technology, and in particular relates to a grinding device for chemical raw materials. Background Technology

[0002] With the rapid development of the chemical industry and the increasing demand for refined production, chemical raw materials, as the basic materials for various products, play a decisive role in the performance of the final products through their processing. In chemical production, grinding equipment, as one of the key pieces of equipment, directly affects the reactivity and dissolution rate of raw materials, as well as the uniformity, stability, and purity of the final products. Therefore, high-efficiency chemical raw material grinding equipment is the core guarantee for achieving high-quality chemical products.

[0003] However, when pre-treating raw materials, existing grinding devices do not make it easy to clean the inner wall of the mixing device. The raw materials will adhere to the inner wall and form dry clumps. After they fall off, they will affect the purity of the subsequent materials and the grinding effect, while also wasting raw materials and increasing the labor cost of cleaning and maintaining the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for chemical raw materials. By setting up a cleaning section, it solves the problem that in existing grinding devices, when pre-treating raw materials, it is not convenient to clean the inner wall of the stirring device. The raw materials will adhere to the inner wall and form dry clumps. After they fall off, they will affect the purity of the subsequent materials and the grinding effect, while also causing raw material waste and increasing the labor cost of equipment cleaning and maintenance.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a grinding device for chemical raw materials, comprising a three-roll mill and an L-shaped support frame fixedly connected to the top of the three-roll mill. A storage tank is fixedly connected between two of the L-shaped support frames. The device further includes: a feeding / discharging section disposed on the storage tank; a cleaning section mounted on the storage tank; a stirring section disposed above the three-roll mill; the cleaning section includes a cleaning assembly disposed on the storage tank; and a power assembly mounted on the storage tank. The cleaning assembly includes a turntable rotatably connected to the inner wall of the storage tank. A plurality of connecting rods are fixedly connected to the bottom of the turntable, and a rotating ring is fixedly connected to the bottom of each connecting rod. A plurality of cleaning rods are fixedly connected to the top of the rotating ring, and the tops of each cleaning rod are fixedly connected to the turntable. The outer wall of the rotating ring is slidably connected to the inner wall of the storage tank.

[0007] Furthermore, the power assembly includes a motor fixedly connected to the top of the storage tank, and the output shaft of the motor is fixedly connected to a rotating shaft via a coupling; the rotating shaft passes through the turntable and is fixedly connected to it.

[0008] Furthermore, the feeding and discharging section includes a feeding pipe connected to the outer wall of the storage tank, a discharging pipe connected to the bottom of the storage tank, and a valve installed on the outer wall of the discharging pipe; the discharging pipe is located below the feeding pipe.

[0009] Furthermore, the stirring section includes a stirring assembly disposed inside the three-roll mill; and an engagement assembly mounted on the three-roll mill. The stirring assembly includes a bracket fixedly connected to the outer wall of a rotating shaft one, through which several rotating shaft two are passed. The outer walls of the several rotating shaft two are fixedly connected to stirring frames, and the outer wall of the rotating shaft one is fixedly connected to several stirring rods. The tops of the several rotating shaft two rotatably pass through a turntable.

[0010] Furthermore, the meshing assembly includes gear 1 fixedly connected to the outer wall of several rotating shafts 2 respectively, and meshing elements are provided on the outer wall of the rotating shaft 1; several gear 1 are distributed in a circumferential array inside the storage tank, and the meshing elements include gear 2 fixedly connected to the outer wall of the rotating shaft 1; several gear 1 are all meshed with gear 2.

[0011] Furthermore, the three-roll mill is an S65 type three-roll mill. Its working principle is as follows: the three rollers are horizontal and rotate at different speeds, following a "slow-fast-slow" pattern, with the front roller being the slowest, the middle roller the fastest, and the rear roller the next fastest. The strong shearing, squeezing, and grinding forces generated by the relatively rotating rollers gradually grind the high-viscosity material fed into the gap between the two rollers into finer particles. At the same time, the gap between the rollers is precisely adjusted by the adjusting mechanism to control the fineness of the material. Finally, the material is scraped off by the scraper from the front roller, which rotates the slowest, thus completing the grinding process.

[0012] This utility model has the following beneficial effects:

[0013] 1. By setting up a cleaning section, the motor of the power component drives the rotating shaft to rotate the rotating disk, connecting rod, rotating ring and cleaning rod of the cleaning component synchronously. The rotating ring slides against the inner wall of the storage tank, and the cleaning rod continuously scrapes the inner wall of the storage tank. Its core significance is to remove the residual chemical raw materials in the storage tank in time, avoid the raw materials from adhering to the inner wall and drying, which will affect the purity and grinding effect of the subsequent materials. At the same time, it reduces raw material waste, reduces the labor cost of equipment cleaning and maintenance, and ensures the long-term stable operation of the grinding device.

[0014] 2. By setting up a stirring section, relying on the rotating shaft of the power component to provide power, the stirring rod of the stirring component rotates around the rotating shaft, and the gear of the meshing component meshes with the gear of the meshing component, so that the rotating shaft drives the stirring frame to rotate in a circular motion while rotating on its own axis. This achieves multi-dimensional and efficient stirring of chemical raw materials in the storage tank. Its significance is that it can fully mix chemical raw materials, avoid the impact of uneven local concentration of raw materials on the grinding efficiency and fineness uniformity of the subsequent three-roll mill, and at the same time prevent raw materials from agglomerating, ensuring that the material smoothly enters the grinding stage through the discharge pipe, providing pretreatment guarantee for high-quality grinding.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
