Description

Technical Field

[0001] This utility model application relates to the field of crusher technology, specifically a crusher for producing fused silica sand. Background Technology

[0002] Fused silica sand is an amorphous form of silicon dioxide (quartz, silica). It is produced by melting natural high-purity silica in an electric furnace at a temperature above 1760℃ and then rapidly cooling it. It is widely used in glass, casting, ceramics and fireproof materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemical and other industries. During the processing of fused silica sand, the quartz stone needs to be heated.

[0003] When quartz is heated, it is crushed to ensure uniformity and heating efficiency. During crushing, the compression causes the surface temperature of the crushing roller to rise. Continued crushing at this temperature can easily lead to deformation of the crushing roller, affecting the service life of the crusher. Summary of the Invention

[0004] To address the problem that existing crushers used in fused silica sand production experience temperature rise and deformation due to compression and friction of the crushing rollers during operation, this invention provides a crusher for fused silica sand production to solve the aforementioned problem.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A crusher for producing fused silica sand includes a crushing box and crushing rollers. The crushing rollers are symmetrically arranged inside the crushing box. A box cover is bolted to the top surface of the crushing box, and a feed hopper is fixed through the center of the box cover. Guide plates are fixed to the bottom surfaces of the box cover on both sides of the bottom of the feed hopper, and the bottom of the guide plates slides against the outer surface of the crushing rollers. Water guide plates are slidably fitted onto the bottom surfaces of the crushing rollers. The outer sides of both water guide plates are fixed to the inner wall of the crushing box. Cooling nozzles are arranged above the two crushing rollers facing away from each other, and a water inlet pipe is fixed through one end of each cooling nozzle extending to the outside of the crushing box. A drain pipe is fixed through the side wall of the crushing box on the bottom surface of the water guide plates.

[0007] Furthermore, a scraper is fixed to the bottom surface of the box cover by bolts, and the bottom surface of the scraper slides against the outer surface of the crushing roller. A sealing plate is fixed to the bottom surface of the box cover and is inserted into the top surface of the crushing box.

[0008] Furthermore, the cooling nozzle directs water towards the outer surface of the crushing roller, the water inlet pipe is connected to the water pump outlet through a water pipe, and the water pump inlet is connected to low-temperature purified water.

[0009] Furthermore, both of the water guide plates are configured to be bent in opposite directions, and the top surface of the water guide plates is configured to be arc-shaped to cooperate with the crushing roller, and the drain pipe is connected to a wastewater tank.

[0010] Furthermore, a filter screen is fixed inside the crushing box below the water guide plate, and the filter screen is tilted to one side. A discharge port is opened on the side wall of the crushing box at the bottom of the tilted side of the filter screen.

[0011] Furthermore, a guide plate that is inclined in the opposite direction to the filter screen is fixed on the bottom surface of the crushing box below the filter screen, and a discharge port 2 is opened in the side wall of the crushing box on the inclined side of the guide plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by rinsing and cooling with water, the crushing roller can be quickly rinsed and cooled during the crushing process, avoiding deformation of the crushing roller surface caused by compression after the temperature rises. It can also prevent residual gravel from affecting the subsequent crushing effect, solving the problem that the crushing roller of the existing crusher used for molten silica sand production is prone to deformation due to temperature rise after compression and friction. It can effectively ensure the service life of the crushing roller.

[0014] 2. In this utility model, through the screening structure at the bottom, after crushing, the crushed stone is filtered through the filter screen, which can quickly separate and export qualified and unqualified crushed stone, making collection convenient and better ensuring the crushing quality.

[0021] Reference Figure 1 , Figure 2 and Figure 3 A crusher for producing fused silica sand includes a crushing box 1 and crushing rollers 3. Crushing rollers 3 are symmetrically arranged inside the crushing box 1. A box cover 4 is bolted to the top surface of the crushing box 1, and a scraper 15 is bolted to the bottom surface of the box cover 4, with the bottom surface of the scraper 15 slidingly contacting the outer surface of the crushing rollers 3. A sealing plate 8 is fixed to the bottom surface of the box cover 4 and inserted into the top surface of the crushing box 1. A feed hopper 2 is fixed through the middle of the box cover 4. Guide plates 5 are fixed to the bottom surfaces of the box cover 4 on both sides of the bottom of the feed hopper 2, with the bottom of the guide plates 5 slidingly contacting the outer surface of the crushing rollers 3. A water guide plate 9 is provided, and the water guide plate 9 is bent in the opposite direction. The top surface of the water guide plate 9 is set as an arc shape to cooperate with the crushing roller 3. The drain pipe 10 is connected to the wastewater tank.

The filter screen 11 is inclined to one side, and a discharge port 12 is opened in the side wall of the crushing box 1 at the bottom of the inclined side of the filter screen 11.

[0024] Specifically, the crushed stone falls onto the filter screen 11. After being filtered by the filter screen 11, the unqualified crushed stone is discharged through the discharge port 12. Under the guidance of the guide plate 13, the unqualified crushed stone is discharged through the discharge port 24.
