Abstract
Description
Technical Field
[0001] The present application relates to the technical field of silicon carbide production, and specifically discloses a device for crushing silicon carbide production waste. Background Art
[0002] During the production of silicon carbide, high-temperature sintering in a resistance furnace will produce a large number of production wastes that are sintered into blocks and have substandard purity. These production wastes are usually recycled in the next batch of silicon carbide smelting. When the production waste is recycled to the next batch of silicon carbide for smelting, since the production waste is a block structure formed by high-temperature sintering, when it is put into the production and processing of the next batch of silicon carbide, the block production waste cannot be fully fused and sintered with the silicon carbide production raw materials due to its large volume. The silicon carbide production waste needs to be crushed and then fused, sintered and smelted with the silicon carbide production raw materials.
[0003] At present, the crushing and processing of silicon carbide production waste is usually directly completed by existing crushing mechanisms such as jaw crushers. The existing jaw crushers are mainly composed of a frame, a main motor, an eccentric shaft, a large pulley, a flywheel, a side guard plate, a toggle plate, a toggle plate back seat, a gap adjustment screw, a reset spring, a fixed jaw plate and a movable jaw plate. The top and bottom ends of the fixed jaw plate and the movable jaw plate respectively constitute a feeding opening and a discharging opening for the material. When the production waste is fed into the feeding opening, since the feeding opening is an open structure, some of the lighter and smaller blocks of production waste are often bounced off and splashed outside the crushing mechanism during feeding, which not only easily injures the staff and poses a safety hazard, but also requires cleaning the splashed production waste after the crushing is completed, which increases the workload and reduces the crushing and processing efficiency of the production waste. Therefore, in view of this, the inventor provides a silicon carbide production waste crushing device to solve the above problems. Utility Model Content
[0004] The utility model aims to solve the problem that in the process of crushing traditional silicon carbide production waste, it is easy to be bounced off by the crushing mechanism and splashed outside the crushing mechanism, which poses a safety hazard and reduces the crushing efficiency of the production waste.
[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a silicon carbide production waste crushing device, including a crushing box, a feed channel detachably mounted on the top of the crushing box and a discharge channel arranged at the bottom of the crushing box, the crushing box is provided with a jaw crusher for crushing the silicon carbide production waste, the interior of the feed channel is provided with a first belt conveyor for feeding the silicon carbide production waste to the jaw crusher, the interior of the discharge channel is provided with a second belt conveyor for discharging the crushed silicon carbide production waste obtained by the jaw crusher, a dust removal part is also provided at the connection between the feed channel and the crushing box, a feed port is provided at the top of the crushing box, an outlet end is provided at one end of the feed channel connected to the crushing box, the outlet end is detachably connected to the feed port, the feed opening, the feed port, the discharge opening and the discharge channel are connected, and the port cross-sectional area of the outlet end of the feed channel is smaller than the cross-sectional area of the feed port.
[0006] The principles and effects of this basic solution are:
[0007] 1. Compared with the prior art, the utility model provides a feed channel and a first belt conveyor to convey the silicon carbide production waste to be crushed into the crushing box through a belt conveyor, and uses the feed channel to shield the feed port of the crushing box to prevent the silicon carbide production waste from being directly input into the crushing box and the shallow feed port of the jaw crushing mechanism, thereby preventing the silicon carbide production waste from splashing outward. At the same time, by making the outlet end of the feed channel smaller than the feed port of the crushing box, the effect of blocking the material from splashing outward is better. By providing a second belt conveyor, it is convenient to discharge the crushed silicon carbide production waste from the crushing box, thereby solving the problem that the traditional silicon carbide production waste is easily bounced off by the crushing mechanism and splashed outside the crushing mechanism during crushing, which poses a safety hazard and reduces the crushing efficiency of the production waste.
[0008] 2. Compared with the prior art, the utility model provides a dust removal component to facilitate the simultaneous dust removal during the transportation of silicon carbide production waste into the crushing box, thereby avoiding the generation of excessive dust during the transportation and crushing of silicon carbide production waste and affecting the environmental quality, ensuring the quality and safety of the working environment for crushing silicon carbide production waste and avoiding excessive dust being inhaled by workers and affecting their health.

The inner wall of the transverse channel is also evenly installed with a plurality of first support rollers equidistantly distributed between the first belt roller and the second belt roller. A feed motor for driving the first belt roller to rotate is installed on the outer side of the feed channel. By setting the first belt conveyor and the feed motor, it is convenient to transport the silicon carbide production waste inside the feed channel.

[0014] Furthermore, the second belt conveyor includes a third belt roller rotatably connected to both sides of the inner wall of one end of the discharge channel, a fourth belt roller rotatably connected to both sides of the inner wall of the other end of the discharge channel, and a second feeding belt cooperatively connected between the third belt roller and the fourth belt roller. A plurality of second support rollers located between the third belt roller and the fourth belt roller are also rotatably connected and installed between the inner walls of both sides of the discharge channel. A belt transmission member for driving the fourth belt roller to rotate is provided between the main motor and the fourth belt roller. By providing the second belt conveyor and the belt transmission member, it is convenient to discharge the silicon carbide production waste obtained by the jaw crusher to the outside of the crushing box, so as to avoid causing the material to be blocked at the bottom of the jaw crusher.

[0021] Among them, Figure 1 As shown, the feed channel 2 is a right-angle channel structure, which includes a transverse channel 10 and a longitudinal channel 11 connected between the end of the transverse channel 10 and the top of the crushing box 1.
