Description

Technical Field

[0001] This utility model relates to a dust removal device, and more specifically, to a mobile casting dust removal device. Background Technology

[0002] In the casting workshop, after the casting is completed, the harmful gases produced directly disperse into the production space. However, the production environment typically only has shared dust collection equipment, which is insufficient to effectively reduce the escape of these gases. Long-term inhalation of these harmful gases can damage the health of on-site workers and create unnecessary safety hazards by affecting the working environment. Existing casting dust collection equipment is complex in structure or requires a large layout space, and its effectiveness in treating harmful gases is also poor. For example, inadequate sealing measures can lead to problems such as the inability to collect white smoke generated during casting in a timely manner.

[0003] For example, Chinese Patent Publication No. CN217041769U, published on July 26, 2022, is entitled "A Mobile Casting Dust Collector". It includes a support frame, a traveling vehicle set on the upper part of the support frame, and a dust collector set on the upper part of the traveling vehicle. The support frame is connected to an exhaust main pipe in the middle, and the exhaust main pipe is provided with several docking valves. The dust collector includes a shell, with a tube sheet on one side of the shell and several filter cartridges on one side of the tube sheet. An air inlet main pipe is provided on one side of the shell, and two air inlet branch pipes are symmetrically provided on both sides of the air inlet main pipe. A gas collection hood is provided at the lower part of the air inlet branch pipe. An induced draft fan is provided on the upper part of the shell. One side of the induced draft fan is connected to the shell through an induced draft pipe. A corrugated pipe is connected to the lower part of the exhaust pipe of the induced draft fan. A first cylinder is provided on both sides of the corrugated pipe, and the lower end of the piston rod of the first cylinder is connected to the lower part of the corrugated pipe. This solution employs a mobile dust collector, reducing the number of dust hoods. The dust collector is positioned above and to the side of the pouring station, ensuring effective dust removal without interfering with the operations of the pouring personnel below, thus improving the space utilization of the factory workshop. However, this solution suffers from poor dust removal efficiency, easily leaking harmful fumes, and failing to address these fumes promptly. Utility Model Content

[0004] This invention overcomes the problems of poor dust removal effect and untimely treatment of harmful fumes in existing casting dust removal devices, and provides a mobile casting dust removal device. This solution effectively prevents harmful fumes from overflowing from the casting riser to the outside of the dust removal hood, while also simplifying the structure of the dust removal device and making the arrangement simple.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a mobile casting dust removal device, including a dust removal hood and a dust removal component disposed on a casting platform. One end of the dust removal component is connected to the top of the dust removal hood, and the other end of the dust removal component is slidably connected to a dust collection pipe. The side of the dust removal hood away from the dust collection pipe can be moved relative to the casting platform through a moving component, and the side of the dust removal hood close to the dust collection pipe is close to the top of the casting platform. The dust removal component connects the dust removal hood and the dust collection pipe. The dust removal component can create negative pressure inside the dust removal hood to absorb and capture the fumes generated during casting. The two ends of the dust removal hood are respectively attached to the casting platform and the dust collection pipe. The dust removal hood only needs to be attached to the casting platform on the side away from the dust collection pipe, and the other side can be attached to the dust collection pipe to fix the dust removal hood. This not only allows the dust removal hood to move, but also reduces the number of support points for the dust removal hood, which simplifies the structural design of the dust removal hood to a certain extent. The simple arrangement method can also guide the sucked-in fumes into the dust collection pipe in a timely manner to prevent the fumes from overflowing.

[0006] Preferably, the dust removal assembly includes a dust collection duct and a dust removal fan. The dust collection duct includes several branches and connects the dust removal hood to the dust removal fan. The multiple branches of the dust collection duct increase the effective suction area on the dust removal hood and ensure uniform suction, enabling the hood to quickly capture smoke and dust.

[0007] Preferably, a filter device is provided between the dust removal hood and the dust collection pipe. The filter device can perform preliminary filtration of the flue gas.

[0008] Preferably, the moving component includes a slide rail located on one side of the pouring platform and rollers located at the bottom of the dust hood, with the slide rail and rollers engaging in a rolling cooperation. The movement of the dust hood and the surface of the pouring platform via the slide rail and rollers effectively reduces movement resistance and improves the movement efficiency of the dust hood.

[0009] Preferably, a sealing component is provided between the dust removal assembly and the dust collection duct. The sealing component can seal the top of the dust collection duct to prevent flue gas leakage from the dust collection duct.

[0010] Preferably, the sealing assembly includes several drive rollers and a sealing strip mounted on the dust collector fan. The sealing strip is wound around the drive rollers and pressed against the dust collection duct by the drive rollers. The sealing strip is guided by the drive rollers and forms an open or closed position above the dust collection duct, ensuring both the dust collection duct's function of collecting flue gas and its sealing effect.

[0011] Preferably, the upper end of the dust collection duct is provided with several support frames along its length, and the support frames are arranged at intervals. The support frames can support the sealing strip on the dust collection duct, prevent the sealing strip from collapsing onto the dust collection duct, and ensure the sealing effect of the sealing strip. At the same time, the interval arrangement of the support frames can ensure that the dust removal components and the dust collection duct are connected.

[0012] Preferably, the upper end of the dust collection duct is provided with a settling groove, the thickness of the sealing strip is adapted to the height of the settling groove, and the width of the sealing strip is adapted to the width of the settling groove. The settling groove above the dust collection duct can accommodate the sealing strip and form a sealing fit with the sealing strip to prevent harmful fumes from escaping from the dust collection duct.

[0013] Preferably, a fixing frame is provided between the dust removal component and the dust removal hood on the side near the dust collection duct. The fixing frame can strengthen the connection between the dust removal hood and the dust removal fan, so that the dust removal hood can be more stably arranged between the dust collection duct and the moving component.

[0014] Preferably, the casting platform is provided with a number of spaced-apart ground holes on at least one side. By excavating these ground holes at fixed intervals on one side of the casting platform, the platform can be connected to structures such as electrical wires and hot air ducts without affecting the movement of the dust collector hood, while ensuring overall structural strength.

[0015] Compared with the prior art, the beneficial effects of this utility model are: (1) It effectively prevents harmful fumes from overflowing from the casting riser to the outside of the dust collector, and at the same time simplifies the structure of the dust collector and makes the arrangement simple; (2) The dust collection pipe is equipped with multiple branch pipes, which can increase the effective suction area on the dust collector and ensure the uniformity of suction, and enable the hood to quickly capture dust; (3) While ensuring that the dust collection components move on the dust collection pipe, it ensures the good sealing effect of the dust collection pipe; (4) It moves quickly, removes dust accurately, avoids obstacles flexibly, is suitable for multi-station casting, and treats dust in real time without spreading.

Detailed Implementation

[0022] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: As Figure 1 The mobile casting dust removal device shown in Figure 4 includes a dust removal hood 1, which has an inverted U-shaped structure. The dust removal hood 1 is arranged on a casting platform 4, and a casting area is provided on the casting platform 4. The two sides of the dust removal hood 1 are respectively arranged on both sides of the casting area, so that the dust removal hood 1 can cover the casting area of ​​the casting platform 4. A dust collection assembly is arranged above the dust collection hood 1. The dust collection assembly includes a dust collection pipe 5 and a dust collection fan 6. The dust collection pipe 5 includes a main pipe and four branch pipes. One end of each of the four branch pipes is connected to the main pipe, and the other end is connected to the four corners of the dust collection hood 1, so that four air inlets are evenly distributed on the top of the dust collection hood 1. The other end of the main pipe of the dust collection pipe 5 is connected to the dust collection fan 6. When the dust collection fan 6 is working, it can generate negative pressure in the dust collection pipe 5, thereby creating negative pressure inside the dust collection hood 1. When the dust collection hood 1 is located above the casting area, the negative pressure inside the dust collection hood 1 can adsorb the smoke and dust generated by the gating and riser of the casting 15 in the casting area into the dust collection pipe 5, realizing the rapid capture of smoke and dust by the dust collection hood 1. The dust collection hood 1 is made of lightweight high-temperature resistant steel plate (such as 310S stainless steel).

[0024] A dust collection pipe 2 is also installed beside the pouring area. The dust collection pipe 2 is supported by the plant support frame at a position level with the top of the dust collection hood 1. In this way, one end of the dust collection component is connected to the top of the dust collection hood 1, and the other end can be attached to the dust collection pipe 2, which can effectively shorten the laying route of the dust collection component. Specifically, the dust collection fan 6 is slidably connected above the dust collection pipe 2. The dust collection fan 6 can move along the length direction of the dust collection pipe 2, which is the same as the length direction of the pouring area. Since the dust collection component is fixed to the dust collection hood 1, the side of the dust collection hood 1 away from the dust collection pipe 2 forms a sliding connection with the side of the pouring area of ​​the pouring platform 4 away from the dust collection pipe 2. In this way, the dust collection hood 1 and the dust collection component as a whole have two support points (one support point is located on the dust collection pipe 2, and the other support point is located on the pouring platform 4). That is to say, only the slide rail 7 structure needs to be arranged on one side of the pouring platform 4 to realize the movement of the dust collection hood 1, reducing the arrangement of the slide rail 7 structure and reducing the difficulty of site layout. Since the dust hood 1 has an inverted U-shaped structure, the side of the dust hood 1 closest to the dust collection pipe 2 will be close to the upper surface of the pouring platform 4. This can ensure that the dust hood 1 covers the pouring area of ​​the pouring platform 4 to the greatest extent and prevent the flue gas from escaping from the lateral sides.

[0025] The dust collector hood 1 and the pouring platform 4 move relative to each other via a moving component 3. Specifically, the moving component 3 includes a slide rail 7 and rollers 8. The slide rail 7 is arranged on the pouring platform 4, and its length is the same as that of the dust collection pipe 2. At the bottom of the dust collector hood 1, four sets of rollers 8 are arranged. Specifically, two sets of square steel pipes 16 are fixedly connected to the bottom of the dust collector hood 1 along the length of the track 7. The steel pipes 16 are spaced apart at both ends of the bottom of the dust collector hood 1. Each set of steel pipes 16 has two sets of spaced through holes 17 at its bottom, and rollers 8 are rotatably connected at the through holes 17. The through holes 17 allow the rollers 8 to pass through the steel pipes 16 and roll in cooperation with the slide rail 7 on the pouring platform 4. Thus, a total of four sets of rollers 8 are arranged at the bottom of the dust collector hood 1, which can greatly improve the movement stability of the dust collector hood 1. A set of inverted U-shaped connecting pipes is also connected between the two sets of square steel pipes 16 to connect the two sets of steel pipes 16 together, ensuring that the four sets of rollers 8 are horizontally consistent and preventing the rollers 8 from being suspended or not working.

[0026] An anti-collision sensor (not shown in the figure) is also pre-embedded in the slide rail 7 to prevent the movement of the dust collector 1 from being obstructed. Of course, a moving component 3 can also be arranged on the side of the dust collector 1 near the dust collection pipe 2, which can further ensure the movement stability of the dust collector 1.

[0027] A filter device 20 is also arranged between the dust hood 1 and the suction pipe 5. The outer shell of the filter device 20 has a structure that is larger at the bottom and smaller at the top. Multiple filter cartridges (not shown in the figure) are arranged inside the outer shell. Four sets of vent holes 18 and four sets of brackets 19 are arranged on the dust hood 1 and corresponding to the positions of the filter device 20. The four sets of brackets 19 can be used to install the filter cartridges, and the vent holes 18 can allow the flue gas in the dust hood 1 to enter the suction pipe 5.

[0028] A fixing frame 13 is installed on the main pipe of the dust collection pipe 5 and near the dust removal fan 6. The fixing frame 13 is a frame composed of horizontal and vertical rods. The fixing frame 13 has an overall L-shaped structure. One end of the fixing frame 13 is fixed to the dust removal fan 6, and the other end of the fixing frame 13 is fixed to the dust removal hood 1. The fixing frame 13 frames the main pipe of the dust collection pipe 5, which makes the integration of the dust removal fan 6, the dust collection pipe 2 and the dust removal hood 1 stronger, improves the connection strength of the three, and ensures that when the dust removal fan 6 moves on the dust collection pipe 2, it can drive the dust removal hood 1 to move together.

[0029] Several ground holes 14 are also provided on the casting platform 4 and on the outside of the slide rail 7. The ground holes 14 are spaced apart and are relatively deep. While ensuring the overall strength, the ground holes 14 can be connected to structures such as wires and hot air pipes without affecting the movement of the dust cover 1.

[0030] Before using the dust removal device, check the equipment wiring for problems and whether there are any obstacles blocking the slide rail 7. If so, remove them promptly to ensure that the height of the casting 15 does not exceed that of the dust removal hood 1. According to the on-site pouring situation, after the casting 15 is poured, move the dust removal hood 1 above the casting 15 through the control panel. Start the dust removal equipment, and when no white smoke is produced at the pouring riser of the casting 15, the equipment can be turned off, and the dust removal hood 1 can be moved to a place that will not affect production. When the first product is poured and you are ready to pour the second product, the dust removal hood 1 can be moved to the side at any time, and then moved back after pouring. This is convenient, quick, and does not affect actual production.

[0031] Example 2: Figure 1As shown in Figure 5, a mobile casting dust removal device includes a dust removal hood 1, which has an inverted U-shaped structure. The dust removal hood 1 is arranged on a casting platform 4, and a casting area is provided on the casting platform 4. The two sides of the dust removal hood 1 are respectively arranged on both sides of the casting area, so that the dust removal hood 1 can cover the casting area of ​​the casting platform 4. A dust collection assembly is arranged above the dust collection hood 1. The dust collection assembly includes a dust collection pipe 5 and a dust collection fan 6. The dust collection pipe 5 includes a main pipe and four branch pipes. One end of each of the four branch pipes is connected to the main pipe, and the other end is connected to the four corners of the dust collection hood 1, so that four air inlets are evenly distributed on the top of the dust collection hood 1. The other end of the main pipe of the dust collection pipe 5 is connected to the dust collection fan 6. When the dust collection fan 6 is working, it can generate negative pressure in the dust collection pipe 5, thereby creating negative pressure inside the dust collection hood 1. When the dust collection hood 1 is located above the casting area, the negative pressure inside the dust collection hood 1 can adsorb the smoke and dust generated by the gating and riser of the casting 15 in the casting area into the dust collection pipe 5, realizing the rapid capture of smoke and dust by the dust collection hood 1. The dust collection hood 1 is made of lightweight high-temperature resistant steel plate (such as 310S stainless steel).

[0032] A dust collection pipe 2 is also installed beside the pouring area. The dust collection pipe 2 is supported by the plant support frame at a position level with the top of the dust collection hood 1. In this way, one end of the dust collection component is connected to the top of the dust collection hood 1, and the other end can be attached to the dust collection pipe 2, which can effectively shorten the laying route of the dust collection component. Specifically, the dust collection fan 6 is slidably connected above the dust collection pipe 2. The dust collection fan 6 can move along the length direction of the dust collection pipe 2, which is the same as the length direction of the pouring area. Since the dust collection component is fixed to the dust collection hood 1, the side of the dust collection hood 1 away from the dust collection pipe 2 forms a sliding connection with the side of the pouring area of ​​the pouring platform 4 away from the dust collection pipe 2. In this way, the dust collection hood 1 and the dust collection component as a whole have two support points (one support point is located on the dust collection pipe 2, and the other support point is located on the pouring platform 4). That is to say, only the slide rail 7 structure needs to be arranged on one side of the pouring platform 4 to realize the movement of the dust collection hood 1, reducing the arrangement of the slide rail 7 structure and reducing the difficulty of site layout. Since the dust hood 1 has an inverted U-shaped structure, the side of the dust hood 1 closest to the dust collection pipe 2 will be close to the upper surface of the pouring platform 4. This can ensure that the dust hood 1 covers the pouring area of ​​the pouring platform 4 to the greatest extent and prevent the flue gas from escaping from the lateral sides.

[0033] The dust collector hood 1 and the pouring platform 4 move relative to each other via a moving component 3. Specifically, the moving component 3 includes a slide rail 7 and rollers 8. The slide rail 7 is arranged on the pouring platform 4, and its length is the same as that of the dust collection pipe 2. At the bottom of the dust collector hood 1, four sets of rollers 8 are arranged. Specifically, two sets of square steel pipes 16 are fixedly connected to the bottom of the dust collector hood 1 along the length of the track 7. The steel pipes 16 are spaced apart at both ends of the bottom of the dust collector hood 1. Each set of steel pipes 16 has two sets of spaced through holes 17 at its bottom, and rollers 8 are rotatably connected at the through holes 17. The through holes 17 allow the rollers 8 to pass through the steel pipes 16 and roll in cooperation with the slide rail 7 on the pouring platform 4. Thus, a total of four sets of rollers 8 are arranged at the bottom of the dust collector hood 1, which can greatly improve the movement stability of the dust collector hood 1. A set of inverted U-shaped connecting pipes is also connected between the two sets of square steel pipes 16 to connect the two sets of steel pipes 16 together, ensuring that the four sets of rollers 8 are horizontally consistent and preventing the rollers 8 from being suspended or not working.

[0034] An anti-collision sensor (not shown in the figure) is also pre-embedded in the slide rail 7 to prevent the movement of the dust collector 1 from being obstructed. Of course, a moving component 3 can also be arranged on the side of the dust collector 1 near the dust collection pipe 2, which can further ensure the movement stability of the dust collector 1.

[0035] A filter device 20 is also arranged between the dust hood 1 and the suction pipe 5. The outer shell of the filter device 20 has a structure that is larger at the bottom and smaller at the top. Multiple filter cartridges (not shown in the figure) are arranged inside the outer shell. Four sets of vent holes 18 and four sets of brackets 19 are arranged on the dust hood 1 and corresponding to the positions of the filter device 20. The four sets of brackets 19 can be used to install the filter cartridges, and the vent holes 18 can allow the flue gas in the dust hood 1 to enter the suction pipe 5.

[0036] A fixing frame 13 is installed on the main pipe of the dust collection pipe 5 and near the dust removal fan 6. The fixing frame 13 is a frame composed of horizontal and vertical rods. The fixing frame 13 has an overall L-shaped structure. One end of the fixing frame 13 is fixed to the dust removal fan 6, and the other end of the fixing frame 13 is fixed to the dust removal hood 1. The fixing frame 13 frames the main pipe of the dust collection pipe 5, which makes the integration of the dust removal fan 6, the dust collection pipe 2 and the dust removal hood 1 stronger, improves the connection strength of the three, and ensures that when the dust removal fan 6 moves on the dust collection pipe 2, it can drive the dust removal hood 1 to move together.

[0037] A sealing assembly is also arranged between the dust collector fan 6 and the dust collection pipe 2. The dust collection pipe 2 has an open structure at the top to ensure that the flue gas sucked in by the suction pipe 5 can enter the dust collection pipe 2. However, to prevent the flue gas from overflowing from the dust collection pipe 2, a sealing assembly needs to be installed at the top of the dust collection pipe 2, without affecting the movement of the dust collector fan 6 on the dust collection pipe 2. Specifically, as shown... Figure 5As shown, four sets of drive rollers 9 are arranged on the dust collector fan 6. The drive rollers 9 are arranged on the front and rear side plates of the fan (the drive rollers 9 are arranged along the width direction of the dust collection pipe 2), and the four drive rollers 9 are arranged in a trapezoidal structure. A sealing strip 10 is wound around the four sets of drive rollers 9. The sealing strip 10 is located above the upper two sets of drive rollers 9 and below the lower two sets of drive rollers 9, and is pressed against the upper surface of the dust collection pipe 2 by the lower two sets of drive rollers 9. In this way, the sealing strip 10 forms an opening with the dust collection pipe 2 at the location of the dust collector fan 6, so that the dust suction pipe 5 can connect to the dust collection pipe 2. At other locations, the sealing strip 10 is in contact with the upper surface of the dust collection pipe 2 to form a seal. This can effectively prevent the flue gas in the dust collection pipe 2 from overflowing.

[0038] A recessed groove 12 is provided at the opening above the dust collection pipe 2. The depth of the recessed groove 12 is adapted to the thickness of the sealing strip 10, so that the sealing strip 10 can be flush with the upper surface of the dust collection pipe 2 after it is attached, ensuring the pressing effect of the transmission roller 9 on the sealing strip 10, while not affecting the movement of the dust collector fan 6. In addition, the width of the recessed groove 12 is also adapted to the width of the sealing strip 10, ensuring that the sealing strip 10 can cover the opening on the dust collection pipe 2.

[0039] In addition, several support frames 11 are installed above the dust collection pipe 2. The support frames 11 are angle steel structures. The support frames 11 are spaced apart and can provide good support for the sealing strip 10. Since the sealing strip 10 is a soft strip, it can effectively prevent the sealing strip 10 from collapsing, thereby ensuring the sealing performance of the sealing strip 10 to the dust collection pipe 2.

[0040] Several ground holes 14 are also provided on the casting platform 4 and on the outside of the slide rail 7. The ground holes 14 are spaced apart and are relatively deep. While ensuring the overall strength, the ground holes 14 can be connected to structures such as wires and hot air pipes without affecting the movement of the dust cover 1.

[0041] Before using the dust removal device, check the equipment wiring for problems and whether there are any obstacles blocking the slide rail 7. If so, remove them promptly to ensure that the height of the casting 15 does not exceed that of the dust removal hood 1. According to the on-site pouring situation, after the casting 15 is poured, move the dust removal hood 1 above the casting 15 through the control panel. Start the dust removal equipment, and when no white smoke is produced at the pouring riser of the casting 15, the equipment can be turned off, and the dust removal hood 1 can be moved to a place that will not affect production. When the first product is poured and you are ready to pour the second product, the dust removal hood 1 can be moved to the side at any time, and then moved back after pouring. This is convenient, quick, and does not affect actual production.
