Description

Technical Field

[0001] This utility model relates to the field of dust suppression equipment technology, specifically a dust suppression device for the production of aluminum-magnesium-carbon molten pool bricks. Background Technology

[0002] Alumina-magnesia-carbon bricks are refractory products made primarily from high-grade alumina bauxite or corundum sand, magnesia sand, and flake graphite. They are lining products formed using high-grade alumina bauxite or corundum sand, magnesia sand, and flake graphite as the main raw materials. Their characteristics include high corrosion resistance and resistance to spalling at high temperatures due to their carbon content, as well as a high residual linear expansion rate due to the formation of spinel when heated. Therefore, they have become a newly developed high-quality lining brick. The production of alumina-magnesia-carbon bricks requires the addition of various raw materials for mixing, but these materials are mostly in powder or granular form, easily generating dust. Inhaling this dust can harm operators and also causes environmental pollution. To improve this situation, a dust suppression device for the production of alumina-magnesia-carbon molten pool bricks is proposed.

[0003] For example, the environmental protection treatment device for the production of magnesia-carbon bricks for steel ladle slag line disclosed in the authorization announcement number CN222890120U includes a support frame. The outer surface of the support frame is respectively provided with a water conveying component, an adjustment component and a dust collection component. A vibrating screen is provided on the side of the support frame. The water conveying component is used to perform dust reduction treatment inside the vibrating screen. The adjustment component is used to change the position of the water conveying component. The dust collection component is used to extract dust inside the vibrating screen. The vibrating screen is used to screen out dust. Although it achieves the connection between the water conveying component and the adjustment component, the adjustment component can drive the water conveying component to rise and fall, so that the water conveying component can move away from or closer to the vibrating screen. Subsequently, the adjustment component can also drive the water conveying component to move away from or closer to the middle part of the vibrating screen at the same time, so as to realize the horizontal movement of the water conveying component. This allows the position of the water conveying component to be adjusted according to the size of the vibrating screen in the actual production process, making it more flexible to use. However, the existing dust suppression equipment does not solve the problem that it is not conducive to flexibly adjusting the dust collection range of flue gas and the stirring of the treatment liquid to make the dust dissolve better in the treatment liquid, and it is not conducive to increasing the uniformity of contact between flue gas dust and treatment liquid, thus affecting the quality of flue gas dust collection and treatment effect. Utility Model Content

[0004] The purpose of this utility model is to provide a dust suppression device for the production of aluminum-magnesium-carbon molten pool bricks, so as to solve the problem mentioned in the background art that the dust suppression device is not convenient to flexibly adjust the gas collection range of flue gas dust and the stirring of the treatment liquid to make the dust better dissolve in the treatment liquid, which is not conducive to increasing the uniformity of contact between flue gas dust and treatment liquid, thus affecting the quality of flue gas dust collection and the treatment effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for the production of aluminum-magnesium-carbon molten pool bricks, comprising a treatment box and a gas collection hood. The treatment box is provided with a gas collection hood on its exterior. An air pump is installed at the center of the top of the gas collection hood. Steel wires are symmetrically installed on the tops of the gas collection hood on both sides of the air pump. A connecting pipe is installed on the top of the air pump. A first adjusting plate is symmetrically and movably installed at the bottom of the gas collection hood. A second adjusting plate is movably installed at the bottom of the gas collection hood on one side of the first adjusting plate. A first cylinder is movably installed on the side wall of the gas collection hood on one side of the first adjusting plate. A first push arm is installed at the output end of each of the first cylinders, and the first push arm is movably connected to the first adjusting plate. A second cylinder is movably installed on the side wall of the gas collection hood on one side of the second adjusting plate. A second push arm is installed at the output end of each of the second cylinders, and the second push arm is movably connected to the second adjusting plate. A flexible connecting plate is installed between the second adjusting plate and the first adjusting plate.

[0006] Preferably, a liquid injection port is installed at the top of the treatment box, and an air outlet pipe is installed on the top of the treatment box on one side of the liquid injection port.

[0007] Preferably, a drive seat is provided on the side wall of the processing box, and an adapter frame is installed on the side wall of the processing box on one side of the drive seat, and the connecting pipe is connected to the adapter frame.

[0008] Preferably, a servo motor is mounted on the side wall of the drive base, and a worm gear is mounted on the output end of the servo motor, with the worm gear being movably connected to the drive base.

[0009] Preferably, a hollow shaft is movably installed inside the drive seat on one side of the worm, and the hollow shaft extends into the interior of the processing box. The hollow shaft is movably connected to the adapter frame. A worm wheel is fitted on the surface of the hollow shaft on one side of the worm, and the worm and the worm wheel mesh with each other.

[0010] Preferably, multiple sets of air outlets are installed on the side wall of the hollow shaft at equal intervals, and the air outlets are connected to the hollow shaft.

[0011] Preferably, a filter block is provided inside the air outlet pipe, and four sets of equally spaced limiting blocks are provided on the outer wall of the filter block.

[0012] Preferably, the inner wall of the air outlet pipe is provided with four sets of equally spaced limiting grooves, and the limiting block is slidably connected to the limiting groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the dust suppression equipment not only realizes the flexible adjustment of the gas collection range of flue gas dust and the stirring of the treatment liquid to make the dust better dissolve in the treatment liquid, which facilitates the increase of the uniformity of contact between flue gas dust and treatment liquid, but also improves the quality of flue gas dust collection and the treatment effect.

[0014] (1) The treatment liquid is injected into the treatment tank through the injection port. The raw material composition of the treatment liquid includes water and acid-base neutralization liquid. The liquid level of the treatment liquid is above the gas outlet. The gas collection hood is installed above the aluminum-magnesium-carbon brick raw material mixing tank by the installation steel wire. When the powdered raw material is stirred, dust will be generated. The air pump draws air into the gas collection hood. Under the suction action of the air pump, the dust enters the interior of the treatment tank through the gas collection hood, connecting pipe, adapter frame, hollow shaft and gas outlet and comes into contact with the treatment liquid. The dust dissolves in the treatment liquid. The air is discharged after being filtered by the filter block. When it is necessary to adjust the gas collection range of the gas collection hood, the second cylinder drives the second push arm to move. The second push arm drives the second adjustment plate to rotate. The first cylinder drives the first push arm to move. The first push arm drives the first adjustment plate to rotate. With the flexible connection of the flexible connecting plate, the angle of the first adjustment plate and the second adjustment plate is adjusted, thereby adjusting the gas collection range of the gas collection hood to better collect the dust and improve the quality of flue gas dust collection.

[0015] (2) To make the contact between flue gas dust and the treatment liquid more uniform, a servo motor drives the worm gear to rotate, which in turn drives the hollow shaft to rotate via the worm wheel. The adapter provides movable support for the hollow shaft, which in turn drives the air outlet to rotate. The air outlet stirs the treatment liquid and simultaneously sprays air into the treatment liquid to make the contact between flue gas dust and the treatment liquid more uniform, allowing the dust to dissolve better in the treatment liquid. After long-term use, the inside of the filter block will be clogged with debris. When it is necessary to clean the filter block... When replacing the filter block, rotate it counterclockwise. With the sliding cooperation between the limiting block and the limiting groove, the filter block drives the limiting block to slide inside the limiting groove. When the limiting block rotates to the turning position of the limiting groove, pull the filter block upward to remove it from the inside of the exhaust pipe. Then, replace it with a new filter block and install it back. This process allows the dust to dissolve better in the treatment liquid, increases the uniformity of contact between the flue gas dust and the treatment liquid, facilitates quick disassembly and replacement of the filter block, and improves the effect of flue gas dust treatment.

The output end of the second cylinder 20 is equipped with a second push arm 19, which is movably connected to the second adjustment plate 15. A flexible connecting plate 16 is installed between the second adjustment plate 15 and the first adjustment plate 14. The top of the treatment box 1 is equipped with a liquid injection port 3, and the top of the treatment box 1 on one side of the liquid injection port 3 is equipped with an air outlet pipe 2. The treatment liquid is injected into the treatment tank 1 through the injection port 3. The raw materials of the treatment liquid include water and acid-base neutralization solution. The liquid level of the treatment liquid is above the gas outlet 13. The gas collection hood 8 is installed above the aluminum-magnesium-carbon brick raw material mixing tank by the installation wire 6. When the powdered raw material is stirred, dust will be generated. At this time, the air pump 7 is turned on, and air is drawn into the gas collection hood 8 by the air pump 7. Under the suction action of the air pump 7, the dust enters the interior of the treatment tank 1 through the gas collection hood 8, connecting pipe 5, adapter frame 21, hollow shaft 12 and gas outlet 13 and comes into contact with the treatment liquid. The dust dissolves in the treatment liquid, and the air passes through the filter block. After filtration by 23, the gas is discharged. When it is necessary to adjust the gas collection range of the gas collection hood 8, the second cylinder 20 is opened, which drives the second push arm 19 to move. The second push arm 19 drives the second adjustment plate 15 to rotate. The first cylinder 17 is opened, which drives the first push arm 18 to move. The first push arm 18 drives the first adjustment plate 14 to rotate. With the flexible connection of the flexible connecting plate 16, the angle of the first adjustment plate 14 and the second adjustment plate 15 is adjusted, thereby adjusting the gas collection range of the gas collection hood 8 to better collect dust and improve the quality of flue gas dust collection.

A servo motor 9 is installed on the side wall of the drive base 4. The servo motor 9 serves as a power drive. A worm gear 10 is installed at the output end of the servo motor 9, and the worm gear 10 is movably connected to the drive base 4. A hollow shaft 12 is movably installed inside the drive seat 4 on one side of the worm 10, and the hollow shaft 12 extends into the interior of the processing box 1. The hollow shaft 12 is movably connected to the adapter frame 21. A worm wheel 11 is fitted on the surface of the hollow shaft 12 on one side of the worm 10, and the worm 10 and the worm wheel 11 mesh with each other.

The inner wall of the air outlet pipe 2 is provided with four sets of equally spaced limiting grooves 24, and the limiting block 22 is slidably connected to the limiting grooves 24. To ensure more uniform contact between flue gas dust and the treatment liquid, the servo motor 9 is activated, driving the worm gear 10 to rotate. Through the meshing of the worm gear 10 and worm wheel 11, the worm gear 10 drives the hollow shaft 12 to rotate. The adapter frame 21 provides movable support for the hollow shaft 12, which in turn drives the exhaust head 13 to rotate. The exhaust head 13 stirs the treatment liquid while simultaneously spraying air into it, further ensuring more uniform contact between the flue gas dust and the treatment liquid, and allowing the dust to dissolve more effectively in the treatment liquid. However, after prolonged use, the interior of the filter block 23 may become clogged with debris. When filter block 23 needs to be replaced, rotate filter block 23 counterclockwise. With the sliding cooperation between limit block 22 and limit groove 24, filter block 23 drives limit block 22 to slide inside limit groove 24. When limit block 22 rotates to the turning position of limit groove 24, pull filter block 23 upward to remove filter block 23 from inside the exhaust pipe 2. Then replace it with a new filter block 23 and install it back. This achieves better dissolution of dust in the treatment liquid by stirring the treatment liquid, increases the uniformity of contact between flue gas dust and treatment liquid, facilitates quick disassembly and replacement of filter blocks, and improves the effect of flue gas dust treatment.

The liquid level of the treatment liquid is above the vent 13. The gas collection hood 8 is installed above the aluminum-magnesium-carbon brick raw material mixing tank by the installation wire 6. When the powdered raw material is stirred, dust will be generated. The air pump 7 draws air into the gas collection hood 8. Under the suction action of the air pump 7, the dust passes through the gas collection hood 8, connecting pipe 5, adapter frame 21, hollow shaft 12 and vent 13 into the interior of the treatment tank 1 and comes into contact with the treatment liquid. Upon contact, the smoke and dust dissolve in the treatment liquid, and the air is discharged after being filtered by the filter block 23.

To better collect dust, the servo motor 9 drives the worm gear 10 to rotate, which in turn drives the hollow shaft 12 to rotate via the worm wheel 11. The adapter frame 21 provides movable support for the hollow shaft 12, which in turn drives the air outlet 13 to rotate. The air outlet 13 stirs the treatment liquid and simultaneously sprays air into the treatment liquid to make the contact between the flue gas dust and the treatment liquid more uniform, allowing the dust to dissolve better in the treatment liquid.
