Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, and more specifically, to a material crushing system that reduces unit consumption. Background Technology

[0002] In acetylene production, clogging in the acetylene generator has always been a key factor affecting production efficiency and equipment stability. The acetylene generator is a crucial piece of equipment for producing acetylene gas; its working principle involves the reaction of calcium carbide (calcium carbide) with water to generate acetylene. However, in actual operation, calcium carbide particles easily accumulate in the reaction zone, causing clogging. This leads to decreased reaction efficiency, unstable equipment operation, and even safety hazards. Clogging also reduces calcium carbide utilization and increases raw material consumption. Existing devices mostly rely on mechanical stirring or airflow impact, but their effectiveness is limited and energy consumption is high. Therefore, a material breaking system that reduces energy consumption is needed to solve these problems. Utility Model Content

[0003] This application provides a material crushing system that reduces unit consumption, solving the problem of material blockage caused by the easy accumulation of calcium carbide particles in the reaction zone during actual operation. This blockage leads to decreased reaction efficiency, unstable equipment operation, and even safety hazards. Furthermore, material blockage also reduces the utilization rate of calcium carbide and increases the unit consumption of raw materials.

[0004] This application provides a material crushing system for reducing unit consumption, including a dust hood, a crusher, and a dust collector. The crusher is housed inside the dust hood, and the crusher includes a primary jaw crusher and a secondary jaw crusher. A conveyor belt is installed below the primary jaw crusher, and the secondary jaw crusher is connected below the conveyor belt. An iron separator is installed above the conveyor belt. The discharge port of the secondary jaw crusher is connected to a bucket elevator, and the upper discharge port of the bucket elevator is connected to a calcium carbide silo. A vibrating filter screen is installed at the discharge port of the calcium carbide silo. A dust outlet is provided at the top of the dust hood, and the dust outlet is connected to the dust collector through a dust collection pipe. A screw conveyor is connected below the dust collector, and the screw conveyor is connected to the bucket elevator.

[0005] Preferably, one end of the conveyor belt is connected to the bottom of the primary jaw crusher via a chute, and the other end of the conveyor belt is connected to the secondary jaw crusher via the chute.

[0006] Preferably, the dust collector includes a dust collection box and a dust collection fan.

[0007] Preferably, the dust removal pipe is connected to the air inlet of the dust removal box, and the air outlet of the dust removal box is connected to the dust removal fan.

[0008] Preferably, the dust collector is provided with a slag outlet at the bottom, and the slag outlet is connected to the screw conveyor.

[0009] Preferably, a support rod is installed on the calcium carbide silo.

[0010] As can be seen from the above technical solution, this application provides a crushing system that reduces unit consumption. In operation, the calcium carbide silo and vibrating filter screen are started first, then the bucket elevator and dust collector are started, and finally the crusher and conveyor belt are started. First, the calcium carbide raw material is fed into the primary jaw crusher. After primary crushing, the raw material is conveyed by the conveyor belt to the secondary jaw crusher for further crushing. After two stages of crushing, the raw material enters the bucket elevator from the discharge port. The bucket elevator conveys the crushed raw material to the calcium carbide silo, and then outputs it from the discharge port of the calcium carbide silo. The calcium carbide filtered by the vibrating filter screen enters the next process through the pipeline. During the crushing process, the dust collector sucks the calcium carbide dust generated during crushing into the dust collection box through the dust collection pipe. The dust particles filtered out in the dust collection box enter the screw conveyor from the slag outlet, and then are transported by the screw conveyor to the bucket elevator. Finally, the bucket elevator transports the calcium carbide to the calcium carbide silo. After the work is completed, the equipment is shut down in the following order: primary jaw crusher, conveyor belt, secondary jaw crusher, dust collector, bucket elevator, and vibrating filter screen. Reverse start and forward stop prevent material from accumulating and blocking at the connection points.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model reduces the material blockage of acetylene generators. By setting up a two-stage jaw crusher, the particle size of calcium carbide is controlled within 50mm, preventing large calcium carbide particles from causing material blockage in the conveying equipment, reducing the risk of material blockage, and improving the continuity and stability of production.

[0013] 2. This utility model adds a dust collection hood to absorb dust, and at the same time uses a screw conveyor to send the dust back to the bucket elevator, which effectively reduces unit consumption, improves raw material utilization, and reduces production costs.

[0014] 3. This utility model sets the entire crushing, conveying, and dust removal system to start in reverse and stop in forward to prevent material from accumulating and clogging at the connection points.

[0015] 4. The iron remover installed above the conveyor belt in this utility model can remove metal foreign objects such as iron plates and iron blocks mixed in with calcium carbide, thereby improving the purity of calcium carbide raw materials.

[0016] In summary, a material crushing system that reduces unit consumption minimizes acetylene generator blockage. By using a two-stage jaw crusher, large calcium carbide particles prevent blockage of the conveying equipment, reducing the risk of blockage, improving production continuity and stability, and adding a dust collector to absorb dust while using a screw conveyor to return the dust to the bucket elevator, the system effectively reduces unit consumption, improves raw material utilization, and lowers production costs.

[0022] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] See Figure 1-2 This application proposes a material crushing system to reduce unit consumption. The system addresses the problem of calcium carbide particles accumulating in the reaction zone, causing blockages that reduce reaction efficiency, disrupt equipment operation, and even pose safety hazards. Blockages also decrease calcium carbide utilization and increase raw material consumption. The system reduces blockages in the acetylene generator by using a two-stage jaw crusher to prevent large calcium carbide particles from clogging the conveying equipment, thus lowering the risk of blockages, improving production continuity and stability, and adding a dust collector to absorb dust. The dust is then conveyed back to the bucket elevator via a screw conveyor, effectively reducing unit consumption, increasing raw material utilization, and lowering production costs.

[0024] Specifically, a material crushing system for reducing unit consumption includes a dust hood 1, a crusher, and a dust collector 14. The dust hood 1 houses the crusher, which includes a primary jaw crusher 2 and a secondary jaw crusher 5. A conveyor belt 3 is located below the primary jaw crusher 2, and the secondary jaw crusher 5 is connected below the conveyor belt 3. One end of the conveyor belt 3 is connected to the primary jaw crusher 2 via a chute 6, and the other end of the conveyor belt 3 is connected to the secondary jaw crusher 5 via the chute 6. Calcium carbide raw material is fed into the primary jaw crusher 2, and the raw material after primary crushing by the primary jaw crusher 2 is conveyed to the secondary jaw crusher 5 by the conveyor belt 3. The crusher 5 continues to crush the calcium carbide, controlling the particle size to within 50mm to prevent large particles from clogging the conveyor. A magnetic separator 4 is installed above the conveyor belt 3 to remove metal foreign objects such as iron plates and blocks mixed in with the calcium carbide, improving the purity of the raw material. The discharge port 7 of the secondary jaw crusher 5 is connected to a bucket elevator 8, and the upper discharge port of the bucket elevator 8 is connected to a calcium carbide hopper 9. A vibrating filter screen 11 is installed at the discharge port 10 of the calcium carbide hopper 9. After two stages of crushing, the raw material enters the bucket elevator 8 from the discharge port 7. The bucket elevator 8 then removes the crushed raw material... The material is conveyed to the calcium carbide silo 9, and then output from the outlet 10 of the calcium carbide silo 9. The calcium carbide filtered by the vibrating filter screen 11 at the outlet 10 enters the next process through the pipeline, while irregular calcium carbide flows out through the screening chute. The dust collector hood 1 has a dust outlet 12 at the top, which is connected to the dust collector 14 through the dust collector pipe 13. A screw conveyor 20 is connected to the bottom of the dust collector 14, and the screw conveyor 20 is connected to the bucket elevator 8. The dust collector 14 includes a dust collector box 15 and a dust collector fan 19. The dust collector pipe 13 is connected to the air inlet 16 of the dust collector box 15, and the air outlet 17 of the dust collector box 15 is connected to the dust collector fan 19. The machine 19 has a slag outlet 18 at the bottom of the dust collection box 15, which is connected to the screw conveyor 20. During the crushing process, the dust collector 14 sucks the calcium carbide dust generated during crushing into the dust collection box 15 through the dust collection pipe 13. The dust particles filtered in the dust collection box 15 enter the screw conveyor 20 through the slag outlet 18, and are then transported by the screw conveyor 20 to the bucket elevator 8. Finally, the bucket elevator 8 transports the calcium carbide to the calcium carbide silo 9, which effectively reduces unit consumption, improves raw material utilization, and reduces production costs. The calcium carbide silo 9 is equipped with a support rod 21, which serves as a fixed support.

[0025] As can be seen from the above technical solution, when using a crushing system that reduces unit consumption, first start the calcium carbide silo 9 and vibrating filter screen 11, then start the bucket elevator 8 and dust collector 14, and finally start the crusher and conveyor belt 3. First, the calcium carbide raw material is put into the primary jaw crusher 2. After primary crushing by the primary jaw crusher 2, the raw material is conveyed by the conveyor belt 3 to the secondary jaw crusher 5 for further crushing, controlling the calcium carbide particle size to within 50mm to prevent large calcium carbide particles from causing blockage of the conveying equipment. The iron remover 4 installed above the conveyor belt 3 can remove metal foreign objects such as iron plates and iron blocks mixed in with the calcium carbide, improving the purity of the calcium carbide raw material. After two stages of crushing, the raw material enters the bucket elevator 8 from the discharge port 7. The bucket elevator 8 discharges the crushed raw material. The material is conveyed to the calcium carbide silo 9, and then output from the discharge port 10 of the calcium carbide silo 9. The calcium carbide filtered by the vibrating filter screen 11 at the discharge port 10 enters the next process through the pipeline. During the crushing process, the dust collector 14 sucks the calcium carbide dust generated during crushing into the dust collector box 15 through the dust collector pipe 13. The dust particles filtered in the dust collector box 15 enter the screw conveyor 20 from the slag outlet 18, and are then conveyed by the screw conveyor 20 to the bucket elevator 8. Finally, the bucket elevator 8 conveys the material back to the calcium carbide silo 9. After the work is completed, the equipment is shut down in the following order: primary jaw crusher 2, conveyor belt 3, secondary jaw crusher 5, dust collector 14, bucket elevator 8, and vibrating filter screen 11. Reverse start and forward stop prevent material from accumulating and blocking at the connection points.
