Description

Technical Field

[0001] The invention relates to the technical field of dust removal equipment, and in particular to a steel casting dust removal device. Background Art

[0002] The dust and smoke generated during the steel casting process have a great impact on the environment and the health of workers. Therefore, special dust removal devices are needed to control and reduce pollution. Conventional steel casting dust removal devices use pneumatic conveying to transport the exhaust gas to the bag dust removal device for dust treatment.

[0003] Bag filter: The dust in the dust-laden gas is filtered out through the filter bag, and the cleaned gas is discharged into the atmosphere, while the collected dust can be subsequently processed and utilized.

[0004] A uniform filtering bag dust collector is disclosed in Chinese patent publication number CN117839334A. The uniform filtering bag dust collector is designed to adjust the flow rate of dust gas when passing through an adjustable flow channel. The dust gas after speed adjustment can be directly sprayed to cage bag filter elements in different columns, so that the cage bag filter elements close to or far away from the diverter can contact the dust gas at the first time, so that all cage bag filter elements can filter the dust gas efficiently and uniformly, thereby improving the filtering effect of the entire dust collector.

[0005] However, since the dust or impurities generated during the steel casting process may contain moisture or oil, during filtration, the moisture or oil will cause the dust to clump and adhere to the outside of the filter cartridge. Simply using pulse jetting cannot blow away the agglomerated dust, which will affect the subsequent filtration effect of the filter cartridge. At the same time, since the dust may contain more fine particles, some larger dust particles attached to the filter bag will be cleaned by pulses, but some smaller dust particles will adhere to the gaps in the filter bag. Since the air generated by the pulse gradually weakens from the top of the filter bag to the bottom, it cannot be completely cleaned by pulses alone. After a long period of dust processing, the filter bag of the bag collector is prone to blockage, especially near the bottom. These particles are easy to block the filter material, resulting in increased system resistance, affecting the dust removal effect and the working efficiency of the fan. Summary of the invention

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] An embodiment of a steel casting dust removal device of the present invention is as follows Figures 1 to 12As shown, it includes a dust removal box body 1, an upper box body 2 is fixedly installed on the top of the dust removal box body 1, an ash hopper 3 is fixedly installed on the bottom of the dust removal box body 1, an ash discharge component 4 is provided at the bottom of the ash hopper 3, an air outlet pipe 201 is fixedly installed on one side of the upper box body 2, a dust air inlet pipe 301 is fixedly installed on one side of the ash hopper 3, a plurality of dust removal components 5 are provided at the bottom of the upper box body 2, the plurality of dust removal components 5 extend to the interior of the dust removal box body 1, a pulse component 6 for spraying airflow into the interior of the plurality of dust removal components 5 is fixedly installed inside the upper box body 2; the dust removal component 5 includes a connector 501 threadedly connected to the upper box body 2, a slide groove 5011 is provided on the outer surface of the connector 501, and the inner surface of the slide groove 5011 is provided with a The movable body is provided with a first clamping member 502 and a second clamping member 503, and the first clamping member 502 and the second clamping member 503 are connected with the slide groove 5011 through an elastic member 5012. The filter bag 504 is fixedly installed at the bottom of the first clamping member 502 and the second clamping member 503, and the bottom of the connecting member 501 is provided with a torsion component 7 for controlling the deformation of the filter bag 504. When the filter bag 504 is blocked, its own gravity causes the first clamping member 502 and the second clamping member 503 to press down the elastic member 5012 to fall, and then the torsion component 7 causes multiple parts of the filter bag 504 to shrink and twist, and when the shape of the filter bag 504 changes, most of the dust particles attached to the outside of the filter bag fall off.

[0034] like Figures 2 to 6 As shown, the torsion assembly 7 includes a fixing ring 701 fixedly mounted on the bottom of the connecting member 501, a conical ring 702 is fixedly mounted on the bottom of the fixing ring 701, a plurality of torsion tightening grooves 703 are provided on the outer surface of the conical ring 702, a plurality of torsion tightening grooves 703 are slidably provided inside the plurality of torsion tightening grooves 703, the torsion pull rods 704 are slidably matched with the torsion tightening grooves 703 through the hinge assembly 8, a plurality of torsion pull rods 704 are movably connected with a turntable 705 at one end away from the torsion tightening grooves 703, a fixing plate 706 is rotatably mounted on the bottom of the turntable 705, a plurality of fixing struts 707 are fixedly mounted on the outer surface of the fixing plate 706, the fixing plate 706 is fixedly mounted on the bottom surface inside the filter bag 504, a plurality of torsion pull rods 704 and a plurality of fixing struts 707 are connected to the inner wall of the filter bag 504, a docking notch 7011 is provided at the upper opening of the fixing ring 701 corresponding to the plurality of torsion tightening grooves 703, as shown in FIG. Fig. 9 As shown, the hinge assembly 8 includes a movable block 801 slidably arranged inside the torsion tightening groove 703, a spherical groove 802 is provided on one side of the movable block 801 close to the torsion pull rod 704, a spherical member 803 is movably connected inside the spherical groove 802, and the outer surface of the spherical member 803 is fixedly connected to the end of the torsion pull rod 704, as shown in FIG. Figures 7 to 9As shown, the torsion tightening groove 703 is an arc groove, and the cross-sectional shape of the torsion tightening groove 703 is T-shaped. The movable block 801 is slidably matched with the torsion tightening groove 703, and the movable block 801 is adapted to the docking notch 7011. A rotating shaft 7061 is fixedly provided at the center of the top of the fixed disk 706, and a rotating hole is provided at the position of the rotating disk 705 corresponding to the rotating shaft 7061. The rotating shaft 7061 is connected with the rotating hole through a bearing, and the ends of the rotating disk 705 corresponding to the multiple torsion pull rods 704 are all provided with plug holes 7051, as shown in FIG. Figure 4 and Figure 6 As shown, the bearings provided can reduce the friction force when the turntable 705 rotates, so that when the movable block 801 slides from the top to the bottom of the torsion tightening groove 703, as shown in FIG. Fig.12 As shown, by utilizing the cooperation between the torsion rod 704 and the socket 7051, the torsion rod 704 can cause the turntable 705 to rotate, and at the same time, the end of the torsion rod 704 can be inserted into the socket 7051, as shown in FIG. Figures 2 to 6 As shown, when the filter bag 504 is blocked, its own gravity causes the first clamping member 502 and the second clamping member 503 to press the elastic member 5012 downward to cause the filter bag 504 to fall. When the filter bag 504 falls, the movable block 801 cooperates with the torsion tightening groove 703 and the conical surface of the conical ring 702, so that when the filter bag 504 falls, the torsion pull rod 704 can twist while pulling the filter bag 504, thereby changing the shape of the filter bag 504, so that part of the filter bag 504 remains in a contracted state. When the shape of the filter bag 504 changes, most of the dust particles attached to the outside of the filter bag 504 fall off, and at the same time, some dust attached to the inside of the gap of the filter bag 504 will be squeezed out.

[0035] like Fig.10 and Fig.11 As shown, the first clamping member 502 and the second clamping member 503 are both semicircular, and the first clamping member 502 and the second clamping member 503 are connected by bolts and nuts. The first clamping member 502 and the second clamping member 503 can be quickly disassembled by the bolts and nuts, so as to facilitate the separation of the first clamping member 502 and the second clamping member 503 from the slide groove 5011 and facilitate the replacement of the filter bag 504.

[0036] like Figure 1 As shown, the ash discharge component 4 includes an ash discharge pipe 401 fixedly installed at the bottom of the ash hopper 3. The ash discharge pipe 401 is provided with a solenoid valve 402. After the dust falls off, it will gather inside the ash hopper 3. Then, the solenoid valve 402 can be opened to discharge the dust from the ash discharge pipe 401, so that the dust can be recycled and reused.

[0037] like Figure 1As shown, the pulse assembly 6 includes a gas tank 601 fixedly mounted on the outer side of the upper box body 2, and a plurality of blowing pipes 602 are fixedly arranged on the outer surface of the gas tank 601, and the plurality of blowing pipes 602 extend to the interior of the upper box body 2, and a venturi tube 603 is fixedly arranged at the openings of the plurality of blowing pipes 602 corresponding to the plurality of dust removal assemblies 5, as shown in FIG. Figures 1 to 6 As shown, by starting the gas tank 601, the high-pressure gas is sprayed from the spray pipe 602 into the multiple venturi tubes 603 in sequence, and then the high-pressure gas is sprayed from the venturi tubes 603 into the filter bag 504. After the filter bag 504 is sprayed, the dust attached to the surface of the filter bag 504 will fall off again, so that the weight of the filter bag 504 becomes lighter. Figures 2 to 9 As shown, when the weight of the filter bag 504 becomes lighter, the first clamping member 502 and the second clamping member 503 no longer press down the elastic member 5012, and then the elastic member 5012 can be used to pull back the first clamping member 502, the second clamping member 503 and the filter bag 504, and then the movable block 801 is used to cooperate with the torsion tightening groove 703 and the conical surface of the conical ring 702 to make the torsion pull rod 704 change from the pulling torsion state to the tightening state, and the torsion part of the filter bag 504 will be unfolded, and its contracted part will also be stretched. When the filter bag 504 goes through the process of unfolding and stretching, the particles attached to its surface can fall off again, and the dust particles attached to the outside of the filter bag 504 are completely detached by the blowing, which effectively ensures the dust removal effect of the filter bag 504.

[0038] The dust removal box 1, upper box 2, ash hopper 3, ash discharge assembly 4, filter bag 504 and pulse assembly 6 described in this application are all well-known technologies in the technical field, so their specific structures and working principles are not described in detail.

[0039] The working process is as follows:

[0040] S1, such as Figure 1 As shown, the dust generated during the casting of the steel part will be sucked into the ash hopper 3 through the dust gas inlet pipe 301, and then filtered by the filter bag 504, allowing the gas to enter the upper box body 2 from the inside of the filter bag 504, and then the gas will be discharged through the outlet pipe 201;

[0041] S2, such as Figure 2 , Figure 3 , Figure 4 and Figure 7 As mentioned above, when the filter bag 504 is not blocked, its own weight is not enough to force the first clamping member 502 and the second clamping member 503 to press the elastic member 5012 downward to make it fall. At this time, the fixed support rod 707 and the torsion rod 704 will tighten the inner wall of the filter bag 504, so that the filter bag 504 remains in the unfolded state.

[0042] S3, such as Figure 2 and Figure 5As shown, when the filter bag 504 is blocked, its own gravity causes the first clamping member 502 and the second clamping member 503 to press the elastic member 5012 downward to fall;

[0043] S4, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig. 9 As shown, when the filter bag 504 falls, the movable block 801 cooperates with the torsion tightening groove 703 and the conical surface of the conical ring 702, so that when the filter bag 504 falls, the torsion pull rod 704 can perform a twisting action while pulling the filter bag 504, thereby changing the shape of the filter bag 504, so that part of the filter bag 504 is kept in a contracted state, and most of the dust particles attached to the outside of the filter bag 504 fall off when the shape of the filter bag 504 changes, and at the same time, part of the dust attached to the inside of the gap of the filter bag 504 will be squeezed out;

[0044] S5, such as Figure 1 As shown, by starting the gas tank 601, the high-pressure gas is sprayed from the spray pipe 602 into the multiple venturi tubes 603 in sequence, and then the high-pressure gas is sprayed from the venturi tubes 603 into the filter bag 504;

[0045] S6, such as Figure 1 and Figure 2 As shown, after the filter bag 504 is sprayed, the dust attached to the surface of the filter bag 504 will fall off again, thereby making the weight of the filter bag 504 lighter;

[0046] S7, such as Figures 2 to 9 As shown, when the weight of the filter bag 504 becomes lighter, the first clamping member 502 and the second clamping member 503 no longer press down the elastic member 5012, and then the elastic member 5012 can be used to pull back the first clamping member 502, the second clamping member 503 and the filter bag 504, and then the movable block 801 is used to cooperate with the torsion tightening groove 703 and the conical surface of the conical ring 702 to make the torsion pull rod 704 change from the pulling torsion state to the tightening state, and the torsion part of the filter bag 504 will be unfolded, and its contracted part will also be stretched. When the filter bag 504 goes through the process of unfolding and stretching, the particles attached to its surface can fall off again, and the dust particles attached to the outside of the filter bag 504 are completely detached by the blowing, which effectively ensures the dust removal effect of the filter bag 504.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
