[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figure 1-3 This utility model provides the following technical solution: a carbon powder pelletizing device for calcium carbide production, including a screening and dust collection component 2, one end of which is fixedly connected to a feeding belt 1, and dust collection ducts 12 are provided on both sides of the bottom end of the screening and dust collection component 2. One end of one dust collection duct 12 is connected to a secondary calcium carbide furnace 11, and the other end of the other dust collection duct 12 is connected to a primary calcium carbide furnace 3. Negative pressure ducts 10 are fixed on one side of both the secondary calcium carbide furnace 11 and the primary calcium carbide furnace 3.

[0018] Specifically, the screening and dust collection assembly 2 includes a processing chamber 21. One end of the feeding belt 1 is fixed to the processing chamber 21.

The bottom of the processing chamber 21 is fixed with a tubular auger conveyor 24. The bottom of the processing chamber 21 is provided with a discharge port 211 corresponding to the tubular auger conveyor 24.
[0019] By adopting the above technical solution, the dried charcoal is conveyed to the processing chamber 21 for processing via the feeding belt 1. At the same time, the charcoal during the processing can be simultaneously conveyed to the dust extraction duct 12 to absorb the charcoal dust, so that the charcoal dust generated during the charcoal screening can be collected and utilized. The charcoal falls from the feed port 22 to the upper end of the screening plate 23. At this time, the reciprocating electric push rod 213 is activated to drive the screening plate 23 to move up and down, so that the charcoal can be vibrated and screened. The usable charcoal at the upper end of the screening plate 23 after screening is shaken out from the discharge port 25 and enters the dust extraction duct 12 to be conveyed to the first-stage calcium carbide furnace 3 and the second-stage calcium carbide furnace 11 to assist in calcium carbide smelting.
[0020] Specifically, a negative pressure fan 27 is fixed to one side of the upper end of the processing chamber 21, a grid plate 28 is connected to one side of the negative pressure fan 27, a connecting frame 210 is fixed to one side of the upper end of the screening plate 23, and a scraper 29 is fixed to the top of the connecting frame 210 corresponding to the grid plate 28.
[0021] By adopting the above technical solution, the negative pressure fan 27 is turned on to extract air while the charcoal is being screened, so that the charcoal ash generated by the falling material and screening is sucked into the grid plate 28 to filter and block it. During the up and down movement of the screening plate 23, the connecting frame 210 and the scraper 29 at its upper end vibrate with the screening plate 23. The nylon bristles inside the scraper 29 can clean the charcoal ash adhering to the surface of the grid plate 28, ensuring the quality of the charcoal ash filtration and blocking and improving the charcoal ash collection effect.
[0022] Specifically, the scraper 29 is filled with nylon bristles, and a dust cover 212 is fixed to the surface of the reciprocating electric push rod 213.
[0023] By adopting the above technical solution, nylon bristles are used to ensure the cleaning effect of scraper 29 on grid plate 28, and dust cover 212 is set to protect reciprocating electric push rod 213 to prevent carbon material from damaging the equipment.
[0024] Specifically, discharge ports 25 are provided on both sides of the processing chamber 21 corresponding to the dust suction duct 12, and a baffle plate 26 is fixed at the upper end of the discharge port 25.
[0025] By adopting the above technical solution, the usable carbon material located on the upper end of the screening plate 23 after screening is shaken out from the discharge port 25 and enters the dust suction duct 12 to be transported to the first-stage calcium carbide furnace 3 and the second-stage calcium carbide furnace 11 to assist in calcium carbide smelting. The baffle plate 26 prevents the carbon material from falling and improves the stability of material feeding.
[0026] Specifically, a negative pressure fan 27 and a grid plate 28 are also installed at the upper end of the negative pressure duct 10, and a flow valve is also sealed on one side of the inside of the negative pressure duct 10.
[0027] By adopting the above technical solution, the negative pressure fan 27 installed at the upper end of the negative pressure duct 10 is turned on to adsorb and treat the carbon dust generated during the smelting of calcium carbide in the first-phase calcium carbide furnace 3 and the second-phase calcium carbide furnace 11.
[0028] Specifically, an exhaust screen is fixed to the top of the coke powder silo 9, and sealing rings are fixed inside the coke powder silo 9 corresponding to the negative pressure air duct 10, the tubular auger conveyor 24, and the tubular auger conveyor 8.
[0029] By adopting the above technical solutions, the sealing and stability of the collection and transportation of charcoal dust and charcoal undersize material are ensured, thereby improving the quality of equipment use.
[0030] The tubular auger conveyor 324, tubular auger conveyor 15, and tubular auger conveyor 28 of this utility model are existing publicly disclosed technologies, and the selected model is YHTLXSSJ00202.
[0031] In this utility model, the reciprocating electric actuator 213 is a prior art technology, and the selected model is M907.
[0032] The high-pressure briquetting machine 6 in this utility model is a previously disclosed technology, and the selected model is LT-YQJ.
[0033] The working principle and usage process of this utility model are as follows: When this utility model is in use, the dried charcoal is conveyed to the processing chamber 21 through the feeding belt 1 for processing. At the same time, the charcoal during the processing can be conveyed to the dust suction duct 12 to absorb the charcoal dust, so that the generated charcoal dust can be collected and utilized while the charcoal is being screened and fed. The charcoal falls from the feed port 22 to the upper end of the screening plate 23. At this time, the reciprocating electric push rod 213 is turned on to drive the screening plate 23 to move up and down, so that the charcoal can be vibrated and screened. The usable charcoal at the upper end of the screening plate 23 after screening is shaken out from the discharge port 25 and enters the dust suction duct 12 to be conveyed to the first-stage calcium carbide furnace 3 and the second-stage calcium carbide furnace 11 to assist in calcium carbide smelting. During the calcium carbide smelting process, the negative pressure fan 27 installed at the upper end of the negative pressure duct 10 is turned on to absorb the generated charcoal dust. While the charcoal is being screened, the negative pressure fan 27 is turned on to extract air, causing the charcoal ash generated from the falling material and screening to be drawn towards the grid plate 28 for filtration. As the screening plate 23 moves up and down, the connecting frame 210 and the scraper 29 at its upper end vibrate with the screening plate 23. The nylon bristles inside the scraper 29 can clean the charcoal ash adhering to the surface of the grid plate 28, ensuring the quality of the charcoal ash filtration and improving the charcoal ash collection effect. After screening, the carbon material undersize material falling to the bottom of the screening plate 23 enters the tubular screw conveyor 24 through the discharge port 211 and is transported to the inside of the coke powder silo 9 for storage. The carbon material dust generated during the operation of the first-phase calcium carbide furnace 3 and the second-phase calcium carbide furnace 11 also enters the coke powder silo 9 for unified treatment. The tubular screw conveyor 28 is turned on to transport the collected carbon material mixture to the mixing tank 7, and the binder is added through the binder inlet 4 for mixing. Then the tubular screw conveyor 15 is turned on to transport the mixed mixture to the high-pressure briquetting machine 6 for briquetting. Workers sample and analyze the finished coke balls produced at the high-pressure briquetting machine 6. Qualified coke balls are re-fed and transported to the first-phase calcium carbide furnace 3 and the second-phase calcium carbide furnace 11 via the feeding belt 1 to participate in production activities. Unqualified coke balls are put back into the high-pressure briquetting machine 6 for secondary briquetting to ensure the quality of the product.
