A dust collection device for fused white corundum

Abstract

This utility model discloses a dust collection device for fused white fused alumina, comprising an air inlet pipe, a U-shaped dust removal pipe, and a buffer pipe. The U-shaped dust removal pipe and the buffer pipe are respectively connected to the top two ends of the air inlet pipe. A positioning plate is fixedly installed on the bottom inner wall of the air inlet pipe. A J-shaped air guide pipe is fixedly installed in the center of the positioning plate through an opening. A bearing is fixedly installed on the outer wall of the other end of the J-shaped air guide pipe, and a metal mesh cover is fixedly installed on the outer ring of the bearing. This utility model introduces dust-containing gas through the air inlet pipe. The gas then enters the rotating metal mesh cover through the J-shaped air guide pipe, dispersing into fine bubbles that enter the U-shaped dust removal pipe. This allows for thorough mixing of the gas and solution, greatly increasing the contact area between the gas and solution, enabling the dust to be fully mixed and adsorbed. This more efficiently removes dust from the gas, effectively reducing the dust emission concentration during the smelting of white fused alumina and minimizing pollution to the surrounding environment.

Description

Technical Field

[0001] This utility model relates to the technical field of dust treatment equipment, specifically to a dust collection device for fused white corundum. Background Technology

[0002] During the production of white fused alumina, the high-temperature smelting process releases a large amount of dust-containing gas. These dust particles are fine and highly concentrated. If they are released directly into the atmosphere without proper treatment, they will seriously deteriorate the surrounding air quality. The fine particulate matter may be inhaled by the human body, harming respiratory health, and will also cause potential damage to the ecological environment such as soil and water bodies.

[0003] Traditional air filtration equipment has significant limitations in treating dusty gases generated during the smelting of white fused alumina. Traditional air filtration equipment primarily employs principles such as filter interception and electrostatic adsorption, and its design and applicable scenarios are mainly for general air purification. It is ineffective in handling high-concentration, complex-component dusty gases generated during the white fused alumina smelting process. During the filtration process, the contact method between the gas and the filter medium is relatively simple, and the contact area is limited. Dust particles cannot fully interact with the filter medium, allowing a large amount of dust to easily penetrate the filter layer, making it difficult to effectively remove dust from the gas. Therefore, we propose an electrofused white fused alumina dust collection device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a dust collection device for fused white corundum to address the aforementioned shortcomings in the technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust collection device for fused white corundum, comprising an air inlet pipe, a U-shaped dust removal pipe, and a buffer pipe. The U-shaped dust removal pipe and the buffer pipe are respectively connected to the top two ends of the air inlet pipe. A positioning plate is fixedly provided on the bottom inner wall of the air inlet pipe. A J-shaped air guide pipe is fixedly provided through an opening at the center of the positioning plate. A bearing is fixedly provided on the outer wall of the other end of the J-shaped air guide pipe. A metal mesh cover is fixedly provided on the outer ring of the bearing. A vertically downward electric motor is provided at the top of the buffer pipe. The output shaft of the electric motor passes through the top outer wall of the buffer pipe and is fixedly provided with a vertically downward rotating rod through a coupling. One bottom end of the rotating rod is fixedly connected to the top center of the metal mesh cover. A vertically downward sedimentation pipe is connected through an opening on the bottom outer wall of the U-shaped dust removal pipe. One bottom end of the sedimentation pipe is connected to a sludge storage tank.

[0006] Preferably, an air intake fan is installed on the top inner wall of the air intake pipe, and a threaded interface is provided at one end of the top of the air intake pipe.

[0007] Preferably, one side of the buffer tube is connected to an upwardly curved exhaust pipe, and an exhaust sleeve is fixedly provided at the top end of the exhaust pipe, with an exhaust fan installed on the inner wall of the exhaust sleeve.

[0008] Preferably, a liquid filling pipe is installed on one side of the outer wall of the buffer tube through an opening, a liquid filling valve is installed on the liquid filling pipe, and a pipe joint is provided at one end of the liquid filling pipe.

[0009] Preferably, a motor mounting cover is fixedly provided at one end of the top of the buffer tube, and the electric motor is fixed to the inner wall of the motor mounting cover.

[0010] Preferably, a drain pipe is connected to one side of the bottom of the sludge storage tank through an opening, and a sealing cap is screwed onto the outer wall of one end of the drain pipe.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0012] After dust-laden gas is introduced through the inlet pipe, it enters the rotating metal mesh through the J-shaped air guide pipe. The gas disperses into fine bubbles and enters the U-shaped dust removal pipe, which can fully mix the gas and the solution, greatly increasing the contact area between the gas and the solution. This allows the dust to be fully mixed and adsorbed with the solution, thus removing dust from the gas more efficiently and effectively reducing the dust emission concentration during the smelting of white fused alumina, thereby reducing pollution to the surrounding environment.

[0022] Refer to the instruction manual appendix Figure 1-3 A dust collection device for fused alumina mainly consists of an air inlet pipe 1, a U-shaped dust removal pipe 2, and a buffer pipe 3 forming the main frame. The U-shaped dust removal pipe 2 and the buffer pipe 3 are respectively connected to the top two ends of the air inlet pipe 1. A positioning plate 4 is fixedly installed on the bottom inner wall of the air inlet pipe 1. An opening is provided in the center of the positioning plate 4, through which a J-shaped air guide pipe 5 is fixedly installed. A bearing is fixedly installed on the outer wall of the other end of the J-shaped air guide pipe 5. A metal mesh cover 6 is fixedly installed on the outer ring of the bearing. A motor fixing cover 9 is fixedly installed on the top of the buffer pipe 3. A vertically downward electric motor 7 is fixedly installed inside the motor fixing cover 9. The output shaft of the electric motor 7 passes through the top outer wall of the buffer pipe 3 and is fixedly connected to a vertically downward rotating rod 8 through a coupling. One bottom end of the rotating rod 8 is fixedly connected to the top center of the metal mesh cover 6. When the electric motor 7 works, it can drive the metal mesh cover 6 to rotate.

[0023] Example 2

[0024] Based on Embodiment 1, the U-shaped dust removal pipe 2 is pre-filled with a solution, and an air intake fan 10 is installed on the top inner wall of the air inlet pipe 1 to draw dust-containing gas into the equipment. A threaded interface is installed at one end of the top of the air inlet pipe 1, which facilitates the connection of this invention with the exhaust end of the white corundum smelting equipment, allowing gas to enter the equipment for dust removal. After entering through the air inlet pipe 1, the dust-containing gas is guided to the metal mesh cover 6 through the J-shaped air guide pipe 5. As the metal mesh cover 6 rotates continuously under the drive of the electric motor 7, the gas is dispersed into fine bubbles when passing through the metal mesh cover 6. These fine bubbles enter the solution inside the U-shaped dust removal pipe 2, greatly increasing the contact area between the gas and the solution, allowing the dust to be fully mixed with the solution and then adsorbed or reacted by the solution for removal.

[0025] Example 3

[0026] Based on Embodiment 1, the bottom outer wall of the U-shaped dust removal pipe 2 is connected to a vertically downward sedimentation pipe 16 through an opening. One end of the bottom of the sedimentation pipe 16 is connected to a sludge storage tank 17. After solution treatment, the dust impurities in the solution will settle in the sedimentation pipe 16 due to gravity and other factors, and eventually fall into the sludge storage tank 17. One side of the bottom of the sludge storage tank 17 is connected to a drain pipe 18 through an opening. One end of the drain pipe 18 is screwed with a sealing cap 19. When a certain amount of dust accumulates in the sludge storage tank 17, the sealing cap 19 can be opened and the dust can be discharged through the drain pipe 18.

[0027] Example 4

[0028] Based on Embodiment 1, one side of the buffer tube 3 is connected to an upwardly curved exhaust pipe 11. An exhaust sleeve 12 is fixedly installed at the top end of the exhaust pipe 11. An exhaust fan 13 is installed on the inner wall of the exhaust sleeve 12. The gas after dust removal is discharged from the equipment through the exhaust pipe 11 and the exhaust sleeve 12 under the action of the exhaust fan 13. A liquid filling pipe 14 is installed on the outer wall of one side of the buffer tube 3 through an opening. A liquid filling valve 15 is installed on the liquid filling pipe 14. One end of the liquid filling pipe 14 is provided with a pipe joint. According to actual needs, an appropriate amount of liquid can be added to the buffer tube 3 through the liquid filling pipe 14 to assist in dust removal or other treatments. The liquid filling valve 15 is used to control the addition of liquid.

[0029] Working principle of this utility model:

[0030] Refer to the instruction manual appendix Figure 1-3In use, this utility model adds an appropriate amount of solution with suitable components to the U-shaped dust removal pipe 2 through the liquid addition pipe 14 to make the solution level reach a suitable height. Then, the liquid addition valve 15 is closed. After that, the screw interface at the top end of the air inlet pipe 1 is connected to the exhaust end of the white fused alumina smelting equipment. Then, the suction fan 10 is turned on to draw the dust-containing gas generated during the white fused alumina smelting process into the air inlet pipe 1. At the same time, the electric motor 7 is started to drive the rotating rod 8 and the metal mesh cover 6 connected to it to rotate. The gas is guided to the rotating metal mesh cover 6 through the J-shaped air guide pipe 5 and dispersed into the solution in the U-shaped dust removal pipe 2. The dust and solution are fully mixed and adsorbed. The dust and impurities are precipitated in the sedimentation pipe 16 and fall into the sludge storage tank 17. The gas after dust removal enters the buffer pipe 3 and is discharged from the equipment through the exhaust fan 13, exhaust pipe 11 and exhaust sleeve 12.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
