Description

Technical Field

[0001] This utility model relates to the technical field of dust collection devices, specifically a dust collection device for a waste tire pyrolysis carbon black production line. Background Technology

[0002] Carbon black is an amorphous carbon, a light, loose and extremely fine black powder with a very large surface area. It is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances under insufficient air conditions. Carbon black has a wide range of applications in the field of polymer modification. It can be used as a black dye to manufacture Chinese ink, ink, paint, etc., and it is also used as a reinforcing agent for rubber.

[0003] With the global annual production of waste tires exceeding 20 million tons, pyrolysis technology has become the mainstream treatment method due to its high resource recovery rate. In the daily process of producing carbon black from tire pyrolysis, dust collection devices are usually used to collect and store the produced carbon black.

[0004] The prior art patent document CN221288993U discloses a dust collection device for a waste tire pyrolysis carbon black production line. The device includes a mounting frame, a support plate fixedly connected to the upper surface of the mounting frame, and a discharge mechanism inside the support plate. A material distribution mechanism is connected to both sides of the upper surface of the discharge mechanism, and a scraping mechanism is provided at one end of the material distribution mechanism. A collection box is connected to the lower end of the scraping mechanism, and a collection container is inserted inside the collection box. This invention uses a first motor to drive a connecting rod to rotate, thereby causing the spiral discharge disc to rotate synchronously. This allows the material to descend and be discharged from the surface of the spiral discharge disc. A blower is activated to blow up the carbon black dust on the material, which then enters the interior of the connecting pipe. This reduces the amount of carbon black dust flying around and, to some extent, prevents air pollution caused by carbon black dust from degrading the environmental quality of the production workshop.

[0005] Although the device has many beneficial effects, it still has the following problems: the single-sided fan causes eddies, the non-driving side of the spiral shaft is prone to powder accumulation, the airflow path inside the connecting pipe needs to be optimized, and the double scraper structure has a scraping blind zone and low scraping efficiency, and the traditional stainless steel scraper blade wears out quickly.

[0034] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0035] This utility model provides an overall structural schematic diagram of an embodiment of a dust collection device for a waste tire pyrolysis carbon black production line, including:

[0036] Please see Figures 1-5 This embodiment of a dust collection device for a waste tire pyrolysis carbon black production line includes a workbench 100. A separation component 200 is provided on the top of the workbench 100. The separation component 200 includes a transmission pipe 210, a spiral blade, and an exhaust fan 223. A transmission component 300 is provided on the side wall of the transmission pipe 210. The transmission component 300 includes a guide rib 330 and a discharge pipe 340. A collection component 400 is provided on the side wall of the discharge pipe 340. The collection component 400 includes a scraper 430. A circular through groove is provided on the top of the workbench 100 at a position corresponding to the collection box 410. A collection frame is welded to the bottom of the circular through groove. A collection box 110 is slidably connected to the inner cavity of the collection frame.

[0037] It is worth noting that, in order to facilitate the separation of carbon black by the separation component 200, the transmission component 300 specifically includes a motor 232. The output end of the motor 232 is connected to a rotating shaft 230. The outer circumference of the rotating shaft 230 passes through the transmission pipe 210 and is welded with spiral blades. The outer circumference of the transmission pipe 210 is fixedly connected to an outer frame 220 by screws. The inner cavity sidewall of the outer frame 220 is fixedly connected to two exhaust fans 223 by screws. The exhaust fans 223 actively blow air to separate the carbon black powder from the material. The inner cavity sidewall of the outer frame 220 is fixedly connected to a filter screen 222 by screws. The carbon black powder on the surface falls into the interior of the outer frame 220. The top of the outer frame 220 is provided with a button 221 that electrically connects the motor 232 and the exhaust fans 223. The sidewall of the outer frame 220 is fixedly connected to a cover plate 224 by screws. The cover plate 224 is a metal plate with multiple ventilation holes on its surface.

[0038] Next, in order to facilitate the transfer of carbon black by the transfer assembly 300, the transfer assembly 300 specifically includes a feed pipe 310, a horizontal flow pipe 320 welded to the side wall of the feed pipe 310, a discharge pipe 340 welded to the side wall of the horizontal flow pipe 320, and multiple guide ribs 330 welded to the inner circumference of the horizontal flow pipe 320 to improve the airflow and increase the airflow velocity.

[0039] Meanwhile, to facilitate the collection of carbon black, the collection assembly 400 specifically includes a collection box 410. A top plate 411 is bolted to the top of the collection box 410. The top of the top plate 411 has an exhaust hole to facilitate the exhaust of air from the inside of the collection box 410 and reduce air pressure. A dustproof net is embedded inside the exhaust hole to prevent carbon black from being discharged. A protective box 420 is bolted to the top of the top plate 411. A second motor 421 is bolted to the bottom of the inner cavity of the protective box 420. A second button electrically connected to the second motor 421 is provided on the side wall of the protective box 420. The output end of the second motor 421 passes through the top plate 411 and connects to the scraper 430.

[0040] Furthermore, in order to improve separation efficiency, specifically, the exhaust fan 223 is symmetrically distributed at 45 degrees to form opposing airflows, thereby improving carbon black separation efficiency. The side wall of the transmission pipe 210 is integrally formed with a connecting pipe, and the inner circumference of the connecting pipe is embedded with a baffle 240 to prevent material from entering the transmission component 300. The side wall of the baffle 240 is provided with multiple air inlets.

[0041] It is worth noting that, in order to improve transmission efficiency, specifically, the feed pipe 310 is a tapered pipe with a cone angle of 15 degrees and the discharge pipe 340 is a tapered pipe with a cone angle of 8 degrees. The airflow is improved through the Venturi effect. The guide ribs 330 are inclined at 15 degrees and spirally distributed on the inner circumference of the horizontal flow pipe 320. There are eight guide ribs 330 near the feed pipe 310 and six guide ribs 330 near the discharge pipe 340. The internal self-cleaning of the horizontal flow pipe 320 is achieved through the flow velocity gradient.

[0042] Finally, to improve the strength of the scraper 430, specifically, the scraper 430 includes a base 431, which is made of polytetrafluoroethylene to reduce the overall weight. The sidewall of the base 431 is fixedly connected with a reinforcing layer 432 by screws to improve the strength of the scraper 430. The reinforcing layer 432 is made of titanium alloy. The sidewall of the base 431 is bonded with a blade 433, which is made of tungsten carbide to reduce the wear of the blade 433 and reduce the metal contamination of carbon black powder.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] Combination Figures 1-5The dust collection device for a waste tire pyrolysis carbon black production line according to this embodiment is used in the following specific process:

[0045] 1: Connect the top of the transfer pipe 210 of the separation component 200 to the storage bin containing the unseparated material via a flange. Press button 221 to drive the rotating shaft 230 and the two exhaust fans 223 to operate synchronously. Then the unseparated material is transferred downward through the threaded blade 231. The two exhaust fans 223 form a counter-current airflow through a 45-degree symmetrical distribution structure, effectively separating the carbon black powder and blowing it to the transfer component 300.

[0046] 2: Carbon black powder first enters the tapered feed pipe 310 through the counter-flow airflow, then enters the interior of the horizontal flow pipe 320 through the guide ribs 330, and then is discharged from the horizontal flow pipe 320 to the tapered discharge pipe 340. The venturi connecting pipe composed of the feed pipe 310, the horizontal flow pipe 320 and the discharge pipe 340 and the guide ribs 330 improve the carbon black powder transmission efficiency, and finally is transmitted to the interior of the collection box 410 through the discharge pipe 340.

[0047] 3: When the carbon black powder is transferred into the collection box 410, press button 2 to turn on motor 2 421. Then motor 2 421 drives the four scrapers 430 to rotate. At the same time, the reinforcing layer 432 of scraper 430 can also improve the strength of scraper 430. Together with the tungsten carbide blade 433, the wear rate of blade 433 is reduced and metal contamination is reduced. Then the carbon black powder falls into the collection box 110 at the bottom of the workbench 100.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
