Description

Technical Field

[0001] The present invention relates to the technical field of waste gas dust removal, and specifically to an exhaust gas dust removal system for waste tire and waste rubber refining equipment. Background Art

[0002] The increase in the number of vehicles has driven economic development. At the same time, the consumption and wear of automobile tires have also generated a lot of waste tires. A few years ago, waste tires were all discarded as garbage, which greatly polluted the environment in which we live. At this time, a new industry quietly emerged, which is the recycling of waste tires. Waste tire refining is a way of treating waste tires. In this process, waste tires are put into a high-temperature and normal-pressure cracking kettle, and after adding a catalyst, the waste tires are heated for catalytic cracking and purification extraction. The oil vapor is fractionated, the oil is decomposed, the oil is condensed into a mixed oil, and then through precipitation, filtration and chemical treatment, the mixed oil is gradually purified into primary diesel. A large amount of waste gas is generated during the waste tire refining process. The waste gas has a large pollution and needs to be treated before being discharged.

[0003] The waste gas generated by common waste tires and waste rubber refining contains dust. The conventional treatment method uses filtration and water flushing to reduce dust in the waste gas. However, in this method, the dust reduction effect by relying solely on spraying is slow, and the dust is likely to accumulate on the filter screen of the dust removal equipment, resulting in a decrease in the gas passing efficiency of the equipment and affecting the waste gas treatment effect. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an exhaust gas dust removal system for waste tire and waste rubber refining equipment to solve the problems raised in the above background art. The structure of the present invention is novel. Through the cooperation of the driving component and the filtering component, the annular filter cylinder rotates cyclically, and the air outlet corresponding to different annular filter cylinders can avoid the problem of the decrease in the gas delivery efficiency caused by blockage. The through holes at multiple angles on the annular filter cylinder can diffuse the waste gas so as to better contact with water for dust reduction. The inside of the annular filter cylinder is cleaned by rotation, the filtered dust is collected, and the filter cylinder is cleaned and dried to maintain high-efficiency waste gas treatment efficiency.

[0005] To achieve the above object, the present invention is realized by the following technical solutions: An exhaust gas dust removal system for waste tire and waste rubber oil refining equipment, including a dust removal box, inside which a filtering component is provided.

An air inlet pipe is arranged at the outer end of the dust removal box corresponding to the air inlet cavity, and the air inlet pipe is inserted into the air inlet cavity. Three air outlet openings are opened at the top of the air inlet cavity, and an annular filter cylinder is rotatably sleeved around the periphery of the central disk. Through holes are equidistantly arranged on the surface of the annular filter cylinder. A spraying rack is fixed on the top of the dust removal box, and an exhaust pipe is fixed on one side of the top of the dust removal box. The other end of the exhaust pipe is connected to a dehumidification box. A driving component is also arranged inside the dust removal box.

The other end of the fixing rod is fixed to the annular filter cylinder. An annular cavity is arranged between the central disk and the annular filter cylinder. Fixing plates are fixed on both sides of the annular filter cylinder and the cavity where the air outlet openings are located. A circular plate is slidably installed inside the annular filter cylinder. A vertical plate is fixed to the bottom of the circular plate, and the vertical plate slides along the cavity.

[0006] Further, the filtering component further includes a moving plate. The moving plate is arranged at the front end of the fixing plate and slides inside the annular filter cylinder and the cavity. A spring is fixed between the moving plate and the fixing plate.

[0007] Further, the inner side of the annular filter cylinder is hollowed out and connected to the central disk. A second notch is opened between the fixing plate and the moving plate at the outer end of the cavity of the central disk, and a first notch is opened between the fixing plate and the moving plate corresponding to the inner side of the cavity of the central disk. Collection cavities are arranged on both sides of the air inlet cavity, and the first notch and the second notch are communicated with the collection cavities.

[0008] Further, top columns are fixed on both sides of the circular plate and the vertical plate, and the top columns alternately press and contact the moving plates on both sides. The structures of the fixing plate and the moving plate are the same as those of the circular plate and the vertical plate.

[0009] Further, a blowing cavity is arranged at the bottom of the air inlet cavity. A blower is fixedly installed on the outer wall of one side of the dust removal box, and an air inlet is opened at the outer end of the blower. The end of the blower facing the annular filter cylinder is provided with an arc-shaped air outlet. A scraper is fixed at the bottom of the air outlet of the blower inside the dust removal box, and the scraper is in sliding contact with the outer surface of the annular filter cylinder.

[0010] Further, a fan is rotatably installed at the center of the blowing cavity through a bearing, and an air outlet pipe is installed at the position of the central disk corresponding to the fan. Ventilation grooves are opened on the surface of the blowing cavity facing the blower.

[0011] Further, a ventilation gap is formed at the top of the central disk between the two moving plates, and baffles are fixed on both sides inside the ventilation gap.

[0012] Further, the driving assembly further includes a gear. The top of the toothed ring is meshed with the gear. The gear is rotatably mounted on the inner wall of the dust removal box through a bearing. A motor is fixed on the outer wall of the dust removal box, and the output end of the motor is fixedly connected to the gear.

[0013] Further, a first connecting rod is rotatably connected to the surface of the gear deviating from the center through a bearing, and the other end of the first connecting rod is rotatably connected to a second connecting rod through a rotating shaft. An annular collar is rotatably mounted on the side surface of the central disk corresponding to the vertical plate. The vertical plate is fixedly connected to the annular collar. The other end of the second connecting rod is rotatably connected to the annular collar through a rotating shaft.

[0014] Further, a water inlet pipe is arranged at the upper end of the dust removal box, and the spray rack is fixed at the bottom of the water inlet pipe. A drain pipe is arranged at the bottom of the dust removal box.

[0015] Advantages of the present invention:

[0016] 1. In the present invention, water is sent to the spray rack through the water inlet pipe to contact and reduce dust with the rising waste gas. Subsequently, the water containing dust falls on the bottom of the dust removal box, and part of it is discharged through the drain pipe. After treatment, the water is recycled. Part of the water remains at the bottom of the dust removal box, and the bottom of the annular filter cartridge can be immersed in water to clean the dust adhered to the annular filter cartridge, keeping the inner and outer walls of the annular filter cartridge free of dust and muddy water.

[0017] 2. In the present invention, the motor drives the gear to rotate. The gear meshes with the toothed ring to drive the rotation of the annular filter cartridge, so that different positions of the annular filter cartridge correspond to the air outlet, thereby maintaining the smoothness of blowing and dust filtration. When the gear rotates, the first connecting rod rotates to drive the second connecting rod to swing, so that the vertical plate and the circular plate led by the annular collar slide left and right reciprocally inside the annular filter cartridge and in the cavity, and are squeezed by the convex columns on the surface to clean the dust filtered in the annular filter cartridge and in the cavity. The second connecting rod is actually a spring telescopic rod, and its length can be adjusted according to the rotation angle requirement of the annular collar, so that the vertical plate and the circular plate can slide reciprocally.

[0018] 3. After being soaked and cleaned, the annular filter cartridge of the present invention rotates to one side of the fan, and the outer surface of the annular filter cartridge is cleaned by the scraper to clean the muddy water, ensuring that there is no dust residue at the outer end of the annular filter cartridge. Through the blowing of the fan, the through holes of the annular filter cartridge and the ventilation grooves of the central disk, the air flow drives the rotation of the fan and is sent out through the air outlet pipe. During this process, the water remaining inside the annular filter cartridge after cleaning can be dried, avoiding the direct adsorption of dust and water stains during the next use, which makes it difficult to clean.

[0019] 4. The circular plate and the vertical plate of the present invention can slide along the annular filter cartridge and the cavity. When moving to one side, they are squeezed by the top column and the moving plate. During the movement of the circular plate and the vertical plate, the inside of the annular filter cartridge and the cavity can be cleaned, and the dust is pushed towards the moving plate side. After being squeezed, the moving plate moves towards the fixed plate, so that the first notch and the second notch are opened, and the circular plate and the vertical plate push the dust into the collection cavity. During this process, the fixed plate not only limits the movement of the moving plate, but also guides the transportation of the dust, making it enter the collection cavity along the inclined surface of the fixed plate. The collection cavity can be opened through the outer wall of the dust removal box to clean the dust.

[0020] 5. Compared with the prior art, in the present invention, through the cooperation of the driving component and the filtering component, the annular filter cartridge rotates cyclically, and the air outlet corresponding to different annular filter cartridges can avoid the problem of reduced gas delivery efficiency caused by blockage. The multi-angle through holes on the annular filter cartridge can diffuse the waste gas so as to better contact with water for dust reduction. By rotating, the inside of the annular filter cartridge is cleaned, the filtered dust is collected, and the filter cartridge is cleaned and dried to maintain high-efficiency waste gas treatment efficiency.

[0031] Please refer to Figures 1 to 8, the present invention provides a technical solution: an exhaust gas dust removal system for waste tire and waste rubber oil refining equipment, including a dust removal box 1. A filtering component 6 is arranged inside the dust removal box 1. The filtering component 6 includes a central disk 63. One side of the central disk 63 is fixed on the inner wall of the dust removal box 1, and an air inlet cavity 64 is arranged inside the central disk 63. An air inlet pipe 11 is arranged at the outer end of the dust removal box 1 corresponding to the air inlet cavity 64, and the air inlet pipe 11 is inserted into the air inlet cavity 64. Three air outlet openings 69 are opened at the top of the air inlet cavity 64, and an annular filter cylinder 61 is rotatably sleeved around the central disk 63. Through holes 62 are equidistantly arranged on the surface of the annular filter cylinder 61. A spraying frame 7 is fixed on the top of the dust removal box 1, and an exhaust pipe 12 is fixed on one side of the top of the dust removal box 1. The other end of the exhaust pipe 12 is connected to a dehumidifying box 2. A driving component 4 is also arranged inside the dust removal box 1. The driving component 4 includes a toothed ring 44, which corresponds to the center of the annular filter cylinder 61. Fixed rods 45 are equidistantly fixed on the edge of the toothed ring 44, and the other ends of the fixed rods 45 are fixed to the annular filter cylinder 61. An annular cavity is arranged between the central disk 63 and the annular filter cylinder 61. Fixed plates 614 are fixed on both sides of the annular filter cylinder 61 and the cavity located at the air outlet openings 69. A circular plate 613 is slidably installed inside the annular filter cylinder 61. A vertical plate 612 is fixed to the bottom of the circular plate 613, and the vertical plate 612 slides along the cavity. When using the device, the gas containing dust is sent into the air inlet cavity 64 from the air inlet pipe 11, and then sent into the annular filter cylinder 61 from the air outlet openings 69 of the air inlet cavity 64. The through holes 62 of the annular filter cylinder 61 filter the dust. The waste gas enters the upper layer. The spraying frame 7 sprays dust-removing water to adsorb and reduce the dust with smaller particles. Then the gas is sent into the dehumidifying box 2 from the exhaust pipe 12. The technical principle of the dehumidifying box 2 can refer to the technical method of patent CN209519534U. The driving component 4 is used to convert the annular filter cylinder 61 and clean the dust inside it.

[0032] In this embodiment, the filtering component 6 further includes a moving plate 615. The moving plate 615 is arranged at the front end of the fixed plate 614. The moving plate 615 slides along the inner side of the annular filter cartridge 6 and inside the cavity. A spring 616 is fixed between the moving plate 615 and the fixed plate 614. The inner side of the annular filter cartridge 6 is hollowed out and connected to the central disc 63. A second notch 619 is formed at the outer end of the cavity of the central disc 63 between the fixed plate 614 and the moving plate 615. A first notch 611 is formed at the inner side of the cavity of the central disc 63 corresponding to the space between the fixed plate 614 and the moving plate 615. Collection cavities 610 are arranged on both sides of the air inlet cavity 64, and the first notch 611 and the second notch 619 are communicated with the collection cavities 610. Push rods 618 are fixed on both sides of the circular plate 613 and the vertical plate 612, and the push rods 618 alternately press against the moving plates 615 on both sides. The structures of the fixed plate 614 and the moving plate 615 are the same as those of the circular plate 613 and the vertical plate 612. The circular plate 613 and the vertical plate 612 can slide along the annular filter cartridge 6 and the cavity. When moving to one side, they are pressed against the moving plate 615 by the push rods 618. During the movement of the circular plate 613 and the vertical plate 612, the inside of the annular filter cartridge 6 and the cavity can be cleaned, and the dust is pushed towards the moving plate 615. After being pressed, the moving plate 615 moves towards the fixed plate 614, so that the first notch 611 and the second notch 619 are opened. The circular plate 613 and the vertical plate 612 push the dust into the collection cavities 610. During this process, the fixed plate 614 not only limits the movement of the moving plate 615, but also guides the transportation of the dust, making it enter the collection cavities 610 along the inclined surface of the fixed plate 614. The collection cavities 610 can be opened through the outer wall of the dust removal box 1 to clean the dust.

[0033] In this embodiment, a blowing chamber 65 is provided at the bottom of the air inlet chamber 64. A blower 5 is fixedly installed on one outer wall of the dust removal box 1, and an air inlet 51 is provided at the outer end of the blower 5. The end of the blower 5 facing the annular filter cartridge 61 is provided with an arc-shaped air outlet. A scraper 8 is fixed at the bottom of the air outlet of the blower 5 inside the dust removal box 1, and the scraper 8 is in sliding contact with the outer surface of the annular filter cartridge 61. A fan 68 is rotatably installed at the center of the blowing chamber 65 through a bearing, and an air outlet pipe 67 is installed at the position of the central disk 63 corresponding to the fan 68. A ventilation groove 66 is provided on the surface of the blowing chamber 65 facing the blower 5. A ventilation gap 617 is provided at the top of the central disk 63 between the two moving plates 615, and baffles 620 are fixed on both sides inside the ventilation gap 617. After the annular filter cartridge 61 is soaked and cleaned, it rotates to one side of the blower 5, and the outer surface of the annular filter cartridge 61 is cleaned by the scraper 8 to clean the muddy water, ensuring that there is no dust residue on the outer end of the annular filter cartridge 61. Through the blowing of the blower 5 and the through holes 62 of the annular filter cartridge 61 and the ventilation grooves 66 of the central disk 63, the air flow drives the rotation of the fan 68 and is sent out from the air outlet pipe 67. During this process, the residual water inside the annular filter cartridge 61 after cleaning can be dried, avoiding the direct adsorption of dust and water stains during the next use, which makes it difficult to clean.

[0034] In this embodiment, the driving assembly 4 further includes a gear 41. The gear 41 is meshed and connected to the top of the toothed ring 44. The gear 41 is rotatably installed on the inner wall of the dust removal box 1 through a bearing. A motor 3 is fixed on the outer wall of the dust removal box 1, and the output end of the motor 3 is fixedly connected to the gear 41. A first connecting rod 42 is rotatably connected to the surface of the gear 41 deviating from the center through a bearing, and the other end of the first connecting rod 42 is rotatably connected to a second connecting rod 43 through a rotating shaft. A collar is rotatably installed on the side surface of the central disk 63 corresponding to the vertical plate 612, and the vertical plate 612 is fixedly connected to the collar. The other end of the second connecting rod 43 is rotatably connected to the collar through a rotating shaft. The motor 3 drives the gear 41 to rotate. The gear 41 meshes with the toothed ring 44 to drive the rotation of the annular filter cartridge 61, so that different positions of the annular filter cartridge 61 correspond to the air outlets, thereby maintaining the smoothness of blowing and dust filtration. When the gear 41 rotates, the first connecting rod 42 rotates to drive the second connecting rod 43 to swing, so that the vertical plate 612 and the circular plate 613 led by the collar slide left and right reciprocally inside the annular filter cartridge 61 and the cavity, and are squeezed by the convex columns on the surface to clean the dust filtered inside the annular filter cartridge 61 and the cavity. The second connecting rod 43 is actually a telescopic rod of the spring 616, and its length can be adjusted according to the requirement of the rotation angle of the collar, so that the vertical plate 612 and the circular plate 613 can slide reciprocally.

[0035] In this embodiment, a water inlet pipe 13 is provided at the upper end of the dust removal box 1, and the spray rack 7 is fixed to the bottom of the water inlet pipe 13. A drain pipe is provided at the bottom of the dust removal box 1. Water is sent to the spray rack 7 through the water inlet pipe 13 to contact the rising waste gas for dust reduction. Subsequently, the water containing dust falls to the bottom of the dust removal box 1, and part of it is discharged through the drain pipe. After treatment, it is recycled. Part of the water remains at the bottom of the dust removal box 1. The bottom of the annular filter cartridge 61 can be immersed in water to clean the dust adhered to the annular filter cartridge 61, so as to keep no dust and muddy water on the inner and outer walls of the annular filter cartridge 61.

[0036] When using the device, the gas containing dust is sent into the intake cavity 64 from the intake pipe 11, and then sent into the annular filter cartridge 61 from the air outlet 69 of the intake cavity 64. The through holes 62 of the annular filter cartridge 61 filter the dust. The waste gas enters the upper layer, and the spray rack 7 sprays dust reduction water to adsorb and reduce the dust of smaller particles. Subsequently, the gas is sent into the dehumidification box 2 from the exhaust pipe 12. The motor 3 drives the gear 41 to rotate. The gear 41 meshes with the toothed ring 44 to drive the rotation of the annular filter cartridge 61, so that different positions of the annular filter cartridge 61 correspond to the air outlet, thus maintaining the smoothness of blowing and dust filtering. When the gear 41 rotates, the first connecting rod 42 rotates to drive the second connecting rod 43 to swing, so that the vertical plate 612 and the circular plate 613 led by the collar slide left and right reciprocally inside the annular filter cartridge 61 and in the cavity, and are extruded through the convex columns on the surface to clean the dust filtered in the annular filter cartridge 61 and the cavity. The circular plate 613 and the vertical plate 612 can slide along the annular filter cartridge 61 and the cavity. When moving to one side, they are extruded by the ejector pin 618 and the moving plate 615. During the movement of the circular plate 613 and the vertical plate 612, the inside of the annular filter cartridge 61 and the cavity can be cleaned, and the dust is pushed towards the moving plate 615. After being extruded, the moving plate 615 moves towards the fixed plate 614, so that the first notch 611 and the second notch 619 are opened. The circular plate 613 and the vertical plate 612 push the dust into the collection cavity 610. During this process, the fixed plate 614 not only limits the moving plate 615, but also guides the conveying of the dust, so that it enters the collection cavity 610 along the inclined surface of the fixed plate 614. The collection cavity 610 can be opened through the outer wall of the dust removal box 1 to clean the dust. After being soaked and cleaned, the annular filter cartridge 61 rotates to the side of the fan 5, and the outer surface of the annular filter cartridge 61 is cleaned by the scraper 8 to clean the muddy water, ensuring that there is no dust residue at the outer end of the annular filter cartridge 61. Through the blowing of the fan 5 and the through holes 62 of the annular filter cartridge 61 and the ventilation slots 66 of the central disc 63, the air flow drives the rotation of the fan 68 and is sent out from the air outlet pipe 67. During this process, the remaining water inside the annular filter cartridge 61 after cleaning can be dried, avoiding the direct adsorption of dust and water stains during the next use, which makes it difficult to clean.
