Description

A crushing device for silicon carbide raw coal

technical field

The utility model relates to the field of silicon carbide smelting, in particular to a crushing device for raw coal used for preparing silicon carbide.

Background technique

When using anthracite to smelt silicon carbide, the raw coal needs to be crushed and ground to a certain extent to make the particle size meet the smelting conditions, so as to further prepare silicon carbide under the high temperature conditions of the smelting furnace. At present, the commonly used crushing process of silicon carbide raw material coal needs to be manually transported and poured into the crusher for gradual crushing. This process requires a lot of human resources, and the feeding speed is uncontrollable and the efficiency is extremely low. At the same time The dust in the dumping process will also further cause environmental pollution.

Contents of the invention

The purpose of the utility model is to provide a crushing device for silicon carbide raw coal, which has high crushing efficiency, saves human resources and reduces environmental pollution.

The technical scheme that the utility model solves this technical problem is:

A crushing device for silicon carbide raw coal, including a raw material bin, a hoist, a screening machine, a crusher, a conveyor, and a finished product bin. The outlet of the raw material bin is located above the inlet at the lower end of the hoist, and the The outlet is connected to the screening machine through the first hopper, and the screening machine is connected to the horizontal transport section of the conveyor in the vertical direction through the second hopper. The screening machine is located above the crusher, and is vertically connected to the crusher through the third hopper. Directly connected, the crusher is connected with the horizontal conveying section of the conveyor through the fourth hopper, and the end of the lifting section of the conveyor is connected with the finished product warehouse in the vertical direction through the fifth hopper.

Both the raw material bin and the finished product bin are equipped with cover plates.

The screening machine is a kind of vibrating screening machine or screw screening machine

The crusher is one of hammer crusher, roller crusher or jaw crusher.

Both the screener and the crusher are equipped with dust bags.

The screens, crushers and conveyor supports are equipped with rubber noise reduction devices.

When the silicon carbide crushing device is used for crushing raw coal, the crushing efficiency can be improved and human resources can be saved. At the same time, the utility model is a fully enclosed device, and no dust diffuses into the air during the crushing process, which is energy-saving and environmentally friendly, and has little environmental pollution.

The accompanying drawing is a structural schematic diagram of a pulverizing device for silicon carbide raw coal of the present invention.

The codes in the drawings are respectively, 1 is the raw material warehouse, 2 is the elevator, 3 is the screening machine, 4 is the crusher, 5 is the conveyor, 6 is the finished product warehouse, 91 is the first hopper, 92 is the second hopper, 93 is the third hopper, 94 is the fourth hopper, and 95 is the fifth hopper.

detailed description

As shown in the drawings, a crushing device for silicon carbide raw coal includes a raw material bin 1, an elevator 2, a screening machine 3, a roller crusher 4, a conveyor 5 and a finished product bin 6, and a cover is installed above the raw material bin 1 Plate, screening machine 3, and roller crusher 4 are all equipped with dust removal bags, and the brackets of screening machine 3, roller crusher 4, and conveyor 5 are all equipped with rubber noise reduction devices, and the discharge port of raw material warehouse 1 is located Above the feed port at the lower end, the discharge port at the upper end of the elevator 2 is connected to the screening machine 3 through the first hopper 91, and the screening machine 3 is connected to the horizontal transport section of the conveyor 5 in the vertical direction through the second hopper 92 , the screening machine 3 is located above the roller crusher 4, and is vertically connected to the roller crusher 4 through the third hopper 93, and the roller crusher 4 is connected to the horizontal transport section of the conveyor 5 through the fourth hopper 94 , the end of the lifting section of the conveyor 5 is vertically connected with the finished product bin 6 through the fifth hopper 95 .

A crushing device using the silicon carbide raw coal of the utility model. During the crushing process of the raw coal, the lump raw coal placed in the raw material bin enters the feed inlet at the lower end of the hoist through the outlet of the raw material bin, and is lifted The transmission device of the machine lifts the raw coal evenly to the discharge port at the upper end, and then enters the screening machine through the first hopper. When the screened product particle size meets the requirements, it enters the horizontal transportation section of the conveyor through the second hopper. When the particle size of the product screened by the screening machine does not meet the requirements, it will enter the crusher through the third hopper, and the product further crushed by the crusher will enter the horizontal transportation section of the conveyor through the fourth hopper, and the products that meet the requirements on the horizontal transportation section The product is transported to the lifting section of the conveyor through the transmission device of the conveyor, and enters the finished product warehouse through the fifth hopper.
