Description

Technical Field

[0001] The invention relates to the technical field of scattered material conveying, and in particular to a traveling dust collector. Background Art

[0002] During the transfer of dusty materials, dusty materials are prone to flying. Therefore, the transfer of dusty materials will not only cause material loss, but also cause a large amount of dusty materials to fly in the workshop. More dusty materials in the workshop will affect the work of the workshop workers. If the dust content in the workshop reaches a certain level, there may be a risk of explosion.

[0003] Some production workshops also have the problem of flying dust and materials. For example, during the aluminum electrolysis production process, the aluminum electrolysis production workshop has a lot of dust and a poor environment. The main reason is that the aluminum oxide flying is caused by the operations of changing poles and cleaning residual poles in the aluminum electrolysis workshop. The leakage of aluminum powder caused by the leakage and overflow of the chute on the upper part of the aluminum electrolysis cell has caused a lot of aluminum oxide to accumulate in the aluminum electrolysis workshop, especially on the upper part of the aluminum electrolysis cell, resulting in alumina powder everywhere in the aluminum electrolysis plant, causing secondary flying and waste of dust and materials.

[0004] The patent document with application number CN202310134246.7 discloses a dust-proof waste recycling device for refractory material production, which discloses tunnel-type dust-proof equipment, fixed-point dust-proof equipment and mobile dust-proof equipment.

[0005] When the fixed-point dust prevention equipment is working: when the raw materials are crushed and enter the hopper of the screening equipment, or the screening is completed and enters the hopper of the mixing equipment, or the mixing is completed and enters the hopper of the metering equipment, the dust collector outside the hopper performs on-site dust collection and material dropping. When the upper-level processing equipment sends a material dropping signal, the negative pressure exhaust device is turned on, and negative pressure is provided to the cavity seat through the vacuum negative pressure cavity. The negative pressure collects the dust to the inside of the cavity seat through the dust collecting hood and the air intake grille. The negative pressure separates the gas and powder through the filter material and the filter screen plate, and the dust falls into the cylindrical silo of the cavity seat. The negative pressure exhaust device and the blower are operated alternately. When the dust falls on the valve plate and accumulates for a certain period of time, the hydraulic motor is activated. The valve plate is rotated 180° to separate the cylindrical silo into two upper and lower chambers. The upper chamber completes dust collection, and the blower introduces the dust collected in the lower chamber into the return material inclined nozzle through the blow pipe, and uses low-pressure blowing to introduce the dust into the bag sleeve to complete dust return and prevent it from overflowing.

[0006] When the mobile dust prevention equipment is working: the dust extraction method of the mobile dust prevention equipment is consistent with the dust extraction method of the fixed-point dust prevention equipment, and the mobile dust prevention equipment continues to extract dust. When dropping materials, the hydraulic cylinder pushes the slider to make the dropping port face the top of the mold cavity, collects the raw materials on the spot and delivers them into the mold cavity on the spot; the timing of the hydraulic cylinder action is: the stamping equipment fall back signal.

[0007] Although the above patent document discloses a mobile dust prevention device, the movement range of the mobile dust prevention device is limited. The dust extraction of the mobile dust prevention device is continuously carried out. When dropping materials, the hydraulic cylinder pushes the slider so that the drop port is directly opposite to the top of the mold cavity, and the raw materials are collected on the spot and delivered into the mold cavity on the spot.

[0008] The patent document with application number CN202023232320.X discloses a dust prevention device for fly ash conveying. When in use, the rocker is rotated, and the rocker drives the screw to rotate, thereby driving the slip ring to slide up and down in the through groove, so that the universal wheel can extend from the base, and the negative pressure suction pump group is moved to the vicinity of the pneumatic conveying mechanism by a push handle, and the screw is shaken to retract the universal wheel into the base, so that the base is placed on the ground, and the suction hose is connected to the top of the cyclone dust collector, and the Roots vacuum pump is driven by a motor to work, and the air in the cyclone dust collector is extracted through the suction hose, so that negative pressure is formed in the cyclone dust collector, thereby drawing the fly ash in the ash bin into the bottom of the cyclone dust collector through the suction pipe, and the extracted airflow is filtered and dust-removed through the cyclone dust collector. The fly ash enters the vacuum buffer tank through the suction hose, and is finally discharged after noise reduction by the muffler installed on the exhaust pipe. The fly ash dust falls into the storage bin. The fly ash tank truck is parked under the support platform, and the bottom of the unloading piece is inserted into the receiving port of the tank truck for unloading. The dust flying out of the receiving port of the tank truck is sealed inside the dust hood to prevent the dust from flying out of the dust hood, and to prevent the dust from polluting the environment and causing harm to the workers. At the same time, the dust suction fan is started, and the dust flying in the dust hood is sucked through the dust suction pipe, and transported into the storage bin through the connecting pipe. The setting of the telescopic sealing enclosure effectively prevents the fly ash from entering the receiving port of the tank truck through the unloading piece. The dust floats out through the gap between the dust hood and the outer wall of the tank truck, polluting the environment and wasting resources. The device is mainly used to avoid dust from dust materials during the transportation of dust materials.

[0009] However, in a workshop with multiple dust and material flying points inside, the technical solutions of the above two patents cannot provide a good solution. Summary of the invention

[0010] The technical problem to be solved by the present invention is to provide a traveling dust collector which is easy to move, occupies little space when not in use, and is suitable for use in workshops with multiple dust material flying points inside.

When the electric telescopic rod is started, the electric telescopic rod can drive the slip ring, the sleeve, the rotating ring and the inner gear ring to move downward along the axial direction of the support rod.

[0017] The inner gear ring is connected to the driving assembly.

[0018] Specifically, the driving assembly includes a motor fixed in the lower end of the sleeve, a gear is coaxially fixed on the output shaft of the motor, and the gear is meshed with the inner gear ring.

The first dust suction holes 25 and the second dust suction holes 7 are staggered up and down.

[0057] The first dust suction pipe 3 is movably connected to the upper end of the axial motion component through the first connecting rod 6. In this embodiment, the number of the first connecting rods 6 is 5. The end of the first connecting rod 6 close to the support rod 8 is tilted upward. Specifically, the end of the first connecting rod 6 away from the support rod 8 is rotatably connected to the upper end of the first dust suction pipe 3 in the circumferential direction of the support rod 8, and the end of the first connecting rod 6 close to the support rod 8 is rotatably connected to the first boss 18 fixed on the outer edge of the slip ring 12. In this embodiment, the number of the first boss 18 is 5. The first boss 18 is threadedly connected with a fastening nut 13 to prevent the first connecting rod 6 from separating from the first boss 18.

The second ear plate 23 is rotatably connected to the first ear plate 10. The number of the first ear plates 10 in this embodiment is 5. The rotation axis of the first ear plate 10 relative to the second ear plate 23 is parallel to the rotation axis of the first dust suction tube 3, and the first ear plate 10 is fixedly connected to the upper end of the second dust suction tube 4. The lower end of the second dust suction tube 4 can not only rotate around the rotation axis of the second ear plate 23, but also around the rotation axis of the first ear plate 10 relative to the second ear plate 23.

[0059] The second dust suction pipe 4 is movably connected to the circumferential rotating assembly through the second connecting rod 5. In this embodiment, the number of the second connecting rods 5 is 5. The end of the second connecting rod 5 close to the support rod 8 is tilted downward.

The ball head 24 is rotatably connected to the ball cavity of the end of the second connecting rod 5 away from the support rod 8, and the second dust suction pipe 4 is located between the first connecting rod 6 and the second connecting rod 5.

[0060] When it is necessary to collect and transfer the dusty materials at the material flying point in the workshop, start the crane in the workshop, and then move the crane dust collector to the top of the material flying point in the workshop or to the side of the material flying point in the workshop. Then start the electric hoist of the crane to make the crane dust collector close to the material flying point in the workshop.

[0061] After the traveling dust collector approaches the material flying point in the workshop, the electric telescopic rod 22 is started, and the electric telescopic rod 22 drives the slip ring 12, the first boss 18, the sleeve 16, the inner gear ring 21, the swivel 15, the motor 14, the second boss 19 and the gear 20 downward. Since the end of the first connecting rod 6 close to the support rod 8 is tilted upward in the initial state, the end of the second connecting rod 5 close to the support rod 8 is tilted downward. Therefore, in the process of the first boss 18 and the second boss 19 moving downward along the axis of the support rod 8, the first boss 18 drives the first connecting rod 6 to move downward at the first end close to the support rod 8, and the lower end of the first dust suction pipe 3 rotates around the axis of the plug shaft 11 in the direction away from the support rod 8. The second boss 19 drives the second connecting rod 5 to move downward at the first end close to the support rod 8, and the lower end of the second dust suction pipe 4 rotates around the rotation axis of the first ear plate 10 and the second ear plate 23 in the direction close to the support rod 8. That is, after the electric telescopic rod 22 drives the axial motion component and the circumferential rotation component to move downward along the axial direction of the support rod 8, the lower end of the first dust suction pipe 3 and the lower end of the second dust suction pipe 4 move away from each other, and the first dust suction pipe 3 and the second dust suction pipe 4 are in an eight-shaped state.

[0062] Then the motor 14 is started, and the motor 14 drives the gear 20 to rotate in the forward direction. When the gear 20 rotates, the swivel 15 and the second protrusion 19 are driven to rotate through the inner gear ring 21. During the rotation of the swivel 15, the swivel 15 drives the lower end of the second dust suction pipe 4 to rotate around the rotation axis of the second ear plate 23 through the second connecting rod 5. After the lower end of the second dust suction pipe 4 rotates around the rotation axis of the second ear plate 23, the first dust suction pipe 3 and the second dust suction pipe 4 are misaligned, and the first dust suction hole 25 and the second dust suction hole 7 are misaligned in the circumferential direction of the support rod 8. At this point, the first dust suction pipe 3 and the second dust suction pipe 4 are unfolded.

[0063] When the exhaust fan is started, the flying dust enters the first dust suction pipe 3 and the second dust suction pipe 4 through the first dust suction hole 25 and the second dust suction hole 7 respectively, and then the dust in the first dust suction pipe 3 and the second dust suction pipe 4 enters the tank body through the bellows, the conveying pipe 1, the hose and the exhaust fan in sequence. After being conveyed into the tank body, the dust material is blocked by the dust bag, and the air in the tank body is discharged through the dust bag, so the dust material is intercepted in the tank body.

[0064] After the first dust suction pipe 3 and the second dust suction pipe 4 are unfolded, the suction area can be increased and the collection efficiency of dust materials can be improved.

[0065] Start the crane to conveniently adjust the position of the crane-mounted dust collector, so that the crane-mounted dust collector can be close to the dust material flying point in the workshop. It is suitable for use in a workshop with multiple dust material flying points inside.

[0066] When it is necessary to retract the first dust suction pipe 3 and the second dust suction pipe 4, the motor 14 is started, and the motor 14 drives the gear 20 to rotate in the opposite direction. When the gear 20 rotates, the swivel 15 and the second protruding column 19 are driven to rotate through the inner gear ring 21. During the rotation of the swivel 15, the swivel 15 drives the lower end of the second dust suction pipe 4 to rotate around the rotation axis of the second ear plate 23 through the second connecting rod 5. After the lower end of the second dust suction pipe 4 rotates around the rotation axis of the second ear plate 23, the first dust suction pipe 3 and the second dust suction pipe 4 are in an eight-shaped state.

[0067] Then the electric telescopic rod 22 is started, and the electric telescopic rod 22 drives the slip ring 12, the first boss 18, the sleeve 16, the inner gear ring 21, the rotating ring 15, the motor 14, the second boss 19 and the gear 20 to move upward. In the process of the first boss 18 and the second boss 19 moving upward along the axis of the support rod 8, the first boss 18 drives the first connecting rod 6 to move upward near the first end of the support rod 8, and the lower end of the first dust suction pipe 3 rotates around the axis of the insertion shaft 11 in the direction close to the support rod 8. At the same time, the second boss 19 drives the second connecting rod 5 to move upward near the first end of the support rod 8, and the lower end of the second dust suction pipe 4 rotates around the rotation axis of the first ear plate 10 and the second ear plate 23 in the direction away from the support rod 8. That is, after the electric telescopic rod 22 drives the axial motion component and the circumferential rotation component to move upward along the axial direction of the support rod 8, the lower end of the first dust suction pipe 3 and the lower end of the second dust suction pipe 4 approach each other, and when the opposite end faces of the first dust suction pipe 3 and the second dust suction pipe 4 contact, the first dust suction pipe 3 and the second dust suction pipe 4 are retracted. At this time, the first dust suction pipe 3 blocks the second dust suction hole 7 on the second dust suction pipe 4, and the second dust suction pipe 4 blocks the first dust suction hole 25 on the first dust suction pipe 3. When the vehicle vacuum cleaner is not used for a long time, dust is prevented from entering the first dust suction pipe 3 and the second dust suction pipe 4 through the first dust suction hole 25 and the second dust suction hole 7.

[0068] When the traveling dust collector is not in use, the first dust suction pipe 3 and the second dust suction pipe 4 can overlap and gather toward the axial direction of the support rod 8, so the traveling dust collector takes up little space when not in use. When not in use, the traveling dust collector can be started to rise in the workshop, and the traveling dust collector does not occupy the space under the factory building after being close to the traveling crossbeam.

[0069] 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 principles of the present invention should be included in the protection scope of the present invention.
