Description

Technical Field

[0001] The utility model belongs to the technical field of smoke and dust treatment, in particular to a smoke and dust treatment device for ladle processing. Background Art

[0002] The main materials used in the ladle are high-aluminum refractory and graphite. High-aluminum refractory has the advantages of high strength and high refractoriness, and is not easily melted at high temperatures. Graphite, on the other hand, can withstand high temperatures and pressure, ensuring the ladle will not rupture. The high-aluminum refractory and graphite are mixed evenly in a certain proportion and poured evenly into the mold. When the molten iron flows into the mold, it comes into contact with the air and the mold during casting, generating a large amount of smoke and dust. This smoke and dust also contains a large amount of floating impurities. Workers operating in the same space will inhale the smoke and dust exhaust, causing great harm to their health. Furthermore, the excessive amount of particulate matter in the smoke and dust does not meet emission standards and environmental protection requirements. Therefore, the smoke and dust must be collected and treated before it can be discharged. Utility Model Content

[0042] like Figure 1-5 As shown, a smoke dust treatment device for ladle processing includes a mobile platform 1, on which four universal wheels 11 are provided to facilitate the movement of the mobile platform 1;

[0043] A smoke treatment box 2 is provided on the mobile platform 1. The left side of the smoke treatment box 2 is connected to a smoke extraction pipe 3, and the right side of the smoke treatment box 2 is connected to an exhaust pipe 4.

[0044] The exhaust pipe 4 is connected to the purification box 6 through the connecting pipe 5, and the purification box 6 is provided with an exhaust pipe 7;

[0045] A plurality of spray nozzles 23 are provided on the top of the smoke treatment box 2, and the spray nozzles 23 are connected to an external water pipe (not shown in the figure). A first baffle 21 and a second baffle 22 are provided inside the smoke treatment box 2, which divide the smoke treatment box 2 from left to right into a first treatment chamber, a second treatment chamber, and a third treatment chamber. The second treatment chamber is connected to the first treatment chamber and the third treatment chamber respectively.

[0046] The exhaust pipe 4 is trumpet-shaped at one end thereof, which is close to the smoke treatment box 1. A rotating shaft 41 is provided in the exhaust pipe 4 for rotation. A first motor 42 is fixedly provided on the right side of the exhaust pipe 4. One end of the rotating shaft 41 extends out of the exhaust pipe 4 and is connected to the first motor 42. A plurality of fan blades 43 are provided on the side of the rotating shaft 41.

[0047] Activated carbon is provided in the purification box 6 .

[0048] The mobile platform 1 is moved to the place where the molten iron ladle is cast, and the exhaust pipe 3 is placed above the casting process. The rotation of the first motor 42 drives the rotating shaft 41 to rotate, and the fan blades 43 rotate to form a vortex air flow pressure. Because the exhaust pipe 4 is close to the end of the smoke treatment box 2 and is trumpet-shaped, the inner diameter of the exhaust pipe 4 gradually decreases from left to right, so that the gas volume in the exhaust pipe 4 is reduced, the air flow pressure is increased, and the gas in the smoke treatment box 2 is promoted to flow to the exhaust pipe 4. Because of the negative pressure, the smoke enters the smoke treatment box 2 from the exhaust pipe 3, and the spray head 23 sprays liquid to reduce the dust of the smoke. The smoke passes through the first treatment chamber, the second treatment chamber and the third treatment chamber in turn, and the dust of the smoke can be reduced step by step. If the smoke contains acidic substances, the spray head 23 can be connected to the alkaline liquid for neutralization to increase the neutralization reaction time. After that, the gas enters the purification box 6 through the exhaust pipe 4 and the connecting pipe 5. After being adsorbed and filtered by the activated carbon in the purification box 6, the smoke is discharged from the exhaust pipe 7.

[0049] Preferably, a filter plate 44 is provided at the connection point between the exhaust pipe 4 and the smoke treatment box 2. By adding the filter plate 44, the filtering effect of particles in the smoke is further improved.

[0050] Preferably, the connecting port between the first treatment chamber and the second treatment chamber is located below the first baffle 21; the connecting port between the second treatment chamber and the third treatment chamber is located above the second baffle 22. The gas enters the first treatment chamber from the upper end of the smoke dust treatment box 2, enters the second treatment chamber from the bottom of the first baffle 21, and then enters the third treatment chamber from the top of the second baffle 22, which increases the flow path of the flue gas, increases the time for the flue gas to fall into dust through the spray head 23, and improves the dust reduction effect of the smoke dust treatment box 2.

[0051] Preferably, a smoke hood 31 is connected below the smoke pipe 3 , and the smoke hood 31 is trumpet-shaped. The trumpet-shaped setting can better collect the generated smoke into the smoke treatment box 2 .

[0052] Preferably, one end of the smoking pipe 3 close to the smoking hood 31 is a retractable structure, and the height of the smoking hood 31 in the vertical direction can be adjusted as needed to better collect the generated smoke.

[0053] Preferably, a purification pipe 61 is provided in the purification box 6, and the purification pipe 61 is spirally arranged. One end of the purification pipe 61 is connected to the connecting pipe 5, and the other end is connected to the exhaust pipe 7. Activated carbon is provided in the purification pipe 61. The spirally arranged purification pipe 61 increases the flow path of the flue gas and improves the adsorption effect.

[0054] Preferably, a lifting assembly 8 is provided on the mobile platform 1 for controlling the universal wheel 11 to be retracted into the mobile platform 1 or extended out of the mobile platform 1;

[0055] The lifting assembly 8 includes two symmetrically arranged connecting rods 81, which are fixedly connected to the two universal wheels 11 on the same side. The two ends of the connecting rods 81 are rotatably provided with first connecting rods 82, and the other end of the first connecting rod 82 is rotatably connected to the moving rod 83;

[0056] A bidirectional threaded rod 84 is rotatably provided in the mobile platform 1. The threads at both ends of the bidirectional threaded rod 84 are in opposite directions. Both ends of the bidirectional threaded rod 84 are threadedly connected to a moving block 85. The moving block 85 is fixedly connected to the two moving rods 83 on the same side. One end of the bidirectional threaded rod 84 extends out of the mobile platform 1 and is connected to a second motor 86.

[0057] Four receiving slots 12 are provided at the bottom of the mobile platform 1 for receiving the universal wheels 11 .

[0058] The second motor 86 drives the bidirectional threaded rod 84 to rotate and drives the moving blocks 85 at both ends to move along the axis of the bidirectional threaded rod 84. The moving blocks 85 drive the moving rod 83 to move. The movement of the moving rod 83 drives the first connecting rod 82 to rotate, thereby pushing the connecting rod 81 to move downward. The universal wheel 11 extends out of the storage slot 12. At this time, the mobile platform 1 can be pushed. After moving the mobile platform 1 to the desired position, the second motor 86 is rotated in the opposite direction to store the universal wheel 11 into the storage slot 12.

[0059] Preferably, sliding rods 87 are provided at both ends of the connecting rod 81 , and the sliding rods 87 are fixed in the mobile platform 1 , and the connecting rod 81 is slidably connected to the sliding rods 87 .

[0060] The working principle of the present invention is as follows: the second motor 86 drives the bidirectional threaded rod 84 to rotate and drives the moving blocks 85 at both ends to move along the axis of the bidirectional threaded rod 84, and the moving block 85 drives the moving rod 83 to move. The movement of the moving rod 83 drives the first connecting rod 82 to rotate, thereby pushing the connecting rod 81 downward, and the universal wheel 11 extends out of the storage groove 12. At this time, the mobile platform 1 is moved to the place where the molten iron ladle is cast, and the second motor 86 is rotated in the opposite direction to store the universal wheel 11 into the storage groove 12, thereby improving the stability of the mobile platform 1, and placing the smoke hood 31 above the casting processing place. The height of the smoke hood 31 in the vertical direction is adjusted as needed to better collect the generated smoke. The first motor 42 rotates to drive the rotating shaft 41 to rotate, and the fan blades 43 rotate to form a vortex airflow pressure Because the end of the exhaust pipe 4 close to the smoke dust treatment box 2 is trumpet-shaped, the inner diameter of the exhaust pipe 4 gradually decreases from left to right, which reduces the volume of the gas in the exhaust pipe 4 and increases the airflow pressure, thereby promoting the gas in the smoke dust treatment box 2 to flow to the exhaust pipe 4. Due to the negative pressure, the flue gas enters the smoke dust treatment box 2 from the exhaust pipe 3, and the spray head 23 sprays liquid to reduce the dust on the flue gas. The flue gas passes through the first treatment chamber, the second treatment chamber and the third treatment chamber in turn, which can gradually reduce the dust on the flue gas. If the flue gas contains acidic substances, the spray head 23 can be connected to an alkaline liquid for neutralization to increase the neutralization reaction time. After that, the gas enters the purification box 6 through the exhaust pipe 4 and the connecting pipe 5. After being adsorbed and filtered by the activated carbon in the purification box 6, the flue gas is discharged from the exhaust pipe 7.

[0061] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
