Description

Technical Field

[0001] This utility model relates to the field of waste tire recycling and processing technology, specifically to a waste tire dust removal and cleaning device. Background Technology

[0002] Waste tires, after being sorted, recycled, and crushed, yield materials such as rubber granules, rubber powder, and steel wire, which can be reused. Waste tire processing is an important aspect of environmental protection and resource recycling. Waste tire cleaning equipment is used to process and clean waste tires, facilitating their reuse or recycling.

[0003] Current technologies for cleaning waste tires primarily involve water washing, using rotary drum cleaning or high-pressure water gun rinsing. Water washing systems are relatively well-developed, and techniques such as counter-current rinsing can reduce water consumption and waste of cleaning resources. While some dust removal processes can separate mud, sand, and gravel before cleaning, the overall operation is inconvenient, time-consuming, and ineffective. Existing waste tire cleaning equipment is mostly suitable for tires in good tread condition, and cannot effectively clean severely worn and misshapen waste tires, indicating low adaptability of the equipment. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects of the existing cleaning and dust removal technology, thereby providing a waste tire dust removal and cleaning device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A waste tire dust removal and cleaning device includes a water washing device, which comprises a washing drum and a washing tank arranged in sequence, as well as a pre-cleaning device and a vibration device. The pre-cleaning device and the vibration device are respectively located at both ends of the water washing device. The pre-cleaning device includes a blowing structure and a dust removal structure arranged in sequence. The blowing structure includes a lifting component, a conveying component, and an air blowing assembly. The dust removal structure is located at the end of the conveying component away from the lifting component. The dust removal structure includes a material dropping assembly and a material pushing assembly. The material dropping assembly is located below the end of the conveyor belt, and the material pushing assembly is installed above the material dropping assembly away from the blowing structure. The vibration device includes a vibrating screen, a vibrating frame, and a vibrating drive component. The vibrating screen is mounted on the vibrating frame and its movement is controlled by the vibrating drive component. The vibrating drive component is installed at the bottom of the vibrating screen. The vibrating screen has a material outlet, an impurity outlet, and a water outlet.

[0007] By adopting the above technical solution, a pre-cleaning device is installed before cleaning waste tires to blow away dust and separate mud, sand, and gravel. The blowing structure realizes the lifting and conveying of waste tires. During the conveying process, surface dust is blown away and the surface of waste tires is smoothed and scraped. The blowing structure has high adaptability and does not need to consider the condition of the tire tread. After the blowing structure is completed, the material falls freely. Under the elasticity of the waste tires themselves, mud, sand, and gravel can be further shaken off, reducing the cleaning pressure of the subsequent water washing equipment. It is easy to operate and has a good dust removal effect, and can also achieve a better water washing effect. After water washing, the waste tires are further vibrated and screened by a vibration device to separate the cleaned particles and fibers, which facilitates the subsequent crushing operation. The two dust removal and cleaning processes before and after ensure the cleanliness of the waste tires.

[0008] Furthermore, the lifting component includes a conveyor belt and a conveyor frame. The conveyor belt is inclined and reciprocates in a closed loop on the conveyor frame. The height of the end of the conveyor belt away from the conveyor is lower than the height of the end near the conveyor. The conveyor includes a conveyor belt, a conveyor frame, and a limiting component. The conveyor belt is horizontally arranged and reciprocates in a closed loop on the conveyor frame. The limiting component is snapped onto both sides of the conveyor belt, and the length of the limiting component is less than the length of the conveyor belt. An air blowing assembly is also installed on the conveyor frame.

[0009] By adopting the above technical solution, the collected waste tires are lifted and transported to the conveyor by the lifting component. The lifting component raises the waste tires to a certain height and then they are transported by the conveyor and fall freely, ensuring that the impact force between the waste tires and the dropping component is sufficient to shake off the mud and dust adhering to the surface. The limiting component flattens and limits the transported waste tires, which facilitates the subsequent dropping process.

[0010] Furthermore, the limiting member is arranged along the length of the conveyor frame, and each side of the limiting member includes a snap-fit ​​block and a limiting net. The snap-fit ​​block snaps into the inner side wall of the conveyor frame near the top, and the limiting net is fixed on the side where the snap-fit ​​blocks are close to each other. The limiting net is arc-shaped and the height of the side that is close to each other is higher than the height of the side that is far away from each other.

[0011] By adopting the above technical solution, the limiting net can handle waste tires with different conveying methods. Waste tires with better tread conditions can be conveyed upright between two limiting nets. Waste tires with better tread conditions can also be cut in half directly at the conveying part with the cutting component, so that the interior can be cleaned during subsequent cleaning. For waste tires with poor tread conditions, they can be flattened and conveyed at the bottom of the limiting net. The limiting net does not affect the operation of the air blowing component when flattening the waste tires.

[0012] Furthermore, the air blowing assembly includes multiple sets of air blowing rods and nozzles. Each air blowing rod is connected to a high-pressure air pump. The nozzles are located at the bottom of the air blowing rods and close to the limiting net. The air blowing rods are inclined and the inclination direction is towards the conveying direction of the conveyor belt.

[0013] By adopting the above technical solution, the air blowing component has a simple structure. It uses high-pressure air to clean some of the dust, mud, stones and other debris from the outer surface of the waste tires. This not only reduces the cleaning pressure of the subsequent cleaning mechanism, but also prevents the stones embedded in the outer surface of the waste tires from easily damaging the cutting tools in the subsequent crushing operation, thus facilitating the subsequent cutting and crushing operation.

[0014] Furthermore, the material receiving assembly includes a receiving frame, a receiving plate, and a dust collection box. The receiving frame is installed on opposite sides of the top of the dust collection box. The receiving plate is movably installed on the top of the dust collection box. A tension spring is provided below the end of the receiving plate near the conveyor belt. The end of the receiving plate away from the conveyor belt is hinged to the top of the dust collection box, and the hinge shaft is arranged along the width direction of the dust collection box. Multiple dust collection holes are arrayed on the receiving plate. A material feeding assembly is installed at the end of the receiving frame away from the conveyor belt.

[0015] By adopting the above technical solution, waste tires fall freely from the conveyor belt onto the receiving plate. Since one end of the receiving plate is hinged to the dust collection box and the other end is equipped with a tension spring, the waste tires will shake under their own weight and elasticity and the reaction force of the tension spring, thereby shaking off surface dust and gravel, and then enter the water washing adhesive equipment.

[0016] Furthermore, the material feeding assembly includes a material feeding drive, a material feeding wheel, and multiple material feeding rods. The material feeding drive is installed on the outer side of the receiving frame and drives the material feeding wheel to rotate. The axis of the material feeding wheel is arranged along the width direction of the dust collection box. The material feeding rods are arranged in a circumferential array on the material feeding wheel and are arranged along the width direction of the dust collection box.

[0017] By adopting the above technical solution, the waste tires piled on the receiving plate will be sequentially and orderly fed into the transfer component or directly into the cleaning drum for cleaning by the material feeding plate.

[0018] Furthermore, the material feeding assembly also includes a material blocking component, which includes multiple material blocking rods and a guide plate. The axis of the material blocking rods is arranged along the width direction of the dust collection box and both ends of the material blocking rods are mounted on the receiving frame. The guide plate is arc-shaped and is installed below the material blocking rods on the side away from the conveyor belt. The top height of the guide plate is flush with the bottom height of the limiting net.

[0019] By adopting the above technical solution, when the waste tires fall from the conveyor belt, a baffle is also set to stop them from falling and jumping out, which can also make it easier to lay the waste tires that are being conveyed vertically flat.

[0020] Furthermore, the vibrating screen is inclined and the height of the side closer to the washing water tank is higher than the height of the side away from the washing water tank. Multiple vibration springs are also provided between the vibrating screen and the vibrating frame. The vibration springs are fixed above the four corners of the vibrating frame. The material outlet is located at the end of the vibrating screen away from the washing water tank. The impurity outlet is located at the front side of the end of the vibrating screen away from the washing water tank. The water outlet is located at the bottom of the end of the vibrating screen away from the washing water tank.

[0021] By adopting the above technical solution, the waste tires after washing may loosen some of the previously stuck impurities. Therefore, after the washing process, the waste tires are vibrated and screened again. This time, the screen mesh size of the vibrating screen is 5-10mm. While vibrating and screening, some water can also be shaken out, which is convenient for the subsequent drying operation of the waste tires.

[0022] In summary, the technical solution of this utility model has the following advantages:

[0023] 1. The waste tire dust removal and cleaning equipment provided by this utility model has two dust removal cleaning processes to ensure the cleanliness of waste tires. Before washing the waste tires, a pre-cleaning device is set up to blow away dust and separate mud, sand and gravel. The material feeding component shakes off the mud, sand and gravel, reducing the cleaning pressure of the subsequent water washing equipment. It is easy to operate and has a good dust removal effect, and can also achieve a better water washing effect. After the water washing is completed, the waste tires are further vibrated and screened by a vibration device to separate the cleaned particles and fibers, which facilitates the subsequent crushing operation.

[0024] 2. The waste tire dust removal and cleaning equipment provided by this utility model has a blowing structure that enables the lifting and conveying of waste tires. During the conveying process, the surface dust is blown away and the surface of the waste tires is smoothed and scraped. The blowing structure has high adaptability and does not need to consider the condition of the tire tread. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0033] A dust removal and cleaning device for waste tires, such as Figure 1 and Figure 2 As shown, the device includes a water-washing adhesive equipment 1, which comprises a cleaning roller 11 and a cleaning water tank 12 arranged in sequence. The cleaning water tank 12 uses a counter-current rinsing function to save water. Both the cleaning roller 11 and the cleaning water tank 12 are existing technologies and will not be described in detail here. It also includes a pre-cleaning device 2 and a vibration device 5, which are respectively located at the left and right ends of the water-washing adhesive equipment 1. The two dust removal cleaning processes ensure the cleanliness of the waste tires. The pre-cleaning device 2 includes a blowing structure 3 and a dust removal structure 4 arranged in sequence. The blowing structure 3 includes a lifting component 31, a conveying component 32, and an air blowing assembly 33. The dust removal structure 4 is located at the end of the conveying component 32 away from the lifting component 31. The dust removal structure 4 includes a material dropping assembly 41 and a material pushing assembly 42. The material dropping assembly 41 is located below the end of the conveyor belt 321, and the material pushing assembly 42 is installed above the material dropping assembly 41 away from the blowing structure 3.

[0034] The vibration device 5 includes a vibrating screen 51, a vibrating frame 52, and a vibration drive 53. The vibrating screen 51 is mounted on the vibrating frame 52 and its movement is controlled by the vibration drive 53. The vibration drive 53 is mounted on the bottom of the vibrating screen 51.

[0035] Before cleaning the waste tires, a pre-cleaning device is installed to blow away dust and separate mud, sand and gravel. The blowing structure 3 realizes the lifting and conveying of waste tires. During the conveying process, the surface dust is blown away and the surface of the waste tires is smoothed and scraped. The blowing structure 3 has high adaptability and does not need to consider the condition of the tire tread. After the blowing structure 3 is completed, the material falls freely. Under the elasticity of the waste tires themselves, mud, sand and gravel can be further shaken off, reducing the cleaning pressure of the subsequent water washing equipment 1. It is easy to operate and has a good dust removal effect, and can also achieve a better water washing effect. After the water washing is completed, the waste tires are further vibrated and screened by the vibration device 5 to separate the cleaned particles and fibers, which is convenient for subsequent crushing operations.

[0036] like Figure 2 and Figure 3 As shown, the lifting component 31 includes a conveyor belt 311 and a conveyor frame 312. The conveyor belt 311 is inclined and reciprocates in a closed loop on the conveyor frame 312. The height of the end of the conveyor belt 311 away from the conveyor 32 is lower than the height of the end near the conveyor 32, that is, the left end of the conveyor belt 311 is lower than the right end of the conveyor belt 311. The collected waste tires are lifted and conveyed to the conveyor 32 by the lifting component 31. The lifting component 31 lifts the waste tires to a certain height and then conveys them to the conveyor 32 before letting them fall freely, ensuring that the impact force of the waste tires with the dropping component 41 is sufficient to shake off the mud and dust adhering to the surface.

[0037] The conveyor 32 includes a conveyor belt 321, a conveyor frame 322, and a limiting member 323. The conveyor belt 321 is horizontally positioned and reciprocates in a closed loop on the conveyor frame 322. The limiting member 323 is snapped onto the front and rear sides of the conveyor belt 321, and its length is less than that of the conveyor belt 321. An air blowing assembly 33 is also installed on the top of the conveyor frame 322. The limiting member 323 flattens and limits the conveyed waste tires, facilitating subsequent unloading.

[0038] like Figure 2 and Figure 3 As shown, the limiting member 323 is arranged along the length of the conveyor frame 322. Each limiting member 323 includes a snap-fit ​​block 3231 and a limiting net 3232. The snap-fit ​​block 3231 snaps into the inner side wall of the conveyor frame 322 near the top. The limiting net 3232 is fixed on the side where the snap-fit ​​blocks 3231 are close to each other. The limiting net 3232 is arc-shaped and the height of the side that is close to each other is higher than the height of the side that is far away from each other. That is, the height of the limiting net 3232 corresponding to the middle of the conveyor belt 321 is higher than the height of the limiting net 3232 corresponding to the edge of the conveyor belt 321.

[0039] The limiting net 3232 can handle waste tires with different conveying methods. Waste tires with better tread conditions can be conveyed upright between two limiting nets 3232. Waste tires with better tread conditions can also be cut in half at the conveyor 32 with the cutting component, so that the interior can be cleaned during subsequent cleaning. For waste tires with poor tread conditions, they can be flattened and conveyed at the bottom of the limiting net 3232. When the limiting net 3232 flattens the waste tires, it does not affect the operation of the air blowing component 33.

[0040] like Figure 2 and Figure 3 As shown, the air blowing assembly 33 includes multiple pairs of air blowing rods 331 and nozzles 332. Each air blowing rod 331 is connected to a high-pressure air pump. The nozzles 332 are located at the bottom of the air blowing rods 331 and close to the limiting net 3232. The air blowing rods 331 are inclined, with the inclination direction facing the conveyor belt 321's conveying direction. The air blowing assembly 33 has a simple structure and uses high-pressure air to clean some dust, mud, stones, etc., from the outer surface of waste tires. This not only reduces the cleaning pressure on subsequent cleaning mechanisms but also prevents stones embedded in the outer surface of waste tires from easily damaging the cutting tools in subsequent crushing operations, facilitating subsequent cutting and crushing operations. The impurities blown off by the air blowing assembly 33 fall into the dust collection box 413 along the conveyor belt 321's conveying direction for easy subsequent cleaning.

[0041] like Figure 2 and Figure 3 As shown, the material receiving assembly 41 includes a receiving frame 411, a receiving plate 412, and a dust collection box 413. The receiving frame 411 is installed on opposite sides of the top of the dust collection box 413. The receiving plate 412 is movably installed on the top of the dust collection box 413. A tension spring 4121 is provided below the end of the receiving plate 412 near the conveyor belt 321. The end of the receiving plate 412 away from the conveyor belt 321 is hinged to the top of the dust collection box 413, and the hinge axis is set along the width direction of the dust collection box 413. Multiple dust collection holes 4122 are arrayed on the receiving plate 412. Waste tires fall freely from the conveyor belt 321 onto the receiving plate 412. Since one end of the receiving plate 412 is hinged to the dust collection box 413 and the other end is provided with a tension spring 4121, the waste tires will shake under their own weight and elasticity and the reaction force of the tension spring 4121, thereby shaking off surface dust and gravel, and then entering the water washing adhesive equipment 1.

[0042] A material-pushing assembly 42 is installed at the end of the receiving frame 411 furthest from the conveyor belt 321. The material-pushing assembly 42 includes a material-pushing drive 421, a material-pushing wheel 422, and multiple material-pushing rods 423. The material-pushing drive 421 is installed on the outer side of the receiving frame 411 and drives the material-pushing wheel 422 to rotate. The material-pushing drive 421 controls the material-pushing wheel 422 to rotate counterclockwise, thereby pushing the waste tires away from the receiving plate 412. The axis of the material-pushing wheel 422 is arranged along the width direction of the dust collection box 413. The material-pushing rods 423 are arranged in a circumferential array on the material-pushing wheel 422 and are arranged along the width direction of the dust collection box 413. The waste tires accumulated on the receiving plate 412 will be pushed sequentially and orderly by the material-pushing plate into the transfer component or directly into the cleaning drum 11 for cleaning.

[0043] like Figure 3 As shown, the material feeding assembly 41 also includes a material blocking component 43, which includes multiple material blocking rods 431 and a guide plate 432. The axis of the material blocking rods 431 is arranged along the width direction of the dust collection box 413, and both ends of the material blocking rods 431 are mounted on the receiving frame 411. The guide plate 432 is arc-shaped and is installed below the material blocking rods 431 on the side away from the conveyor belt 321. The top height of the guide plate 432 is flush with the bottom height of the limiting net 3232. When the waste tires fall from the conveyor belt 321, the material blocking component 43 is also set to block them, preventing them from falling and jumping out, and also making it easier to lay the vertically conveyed waste tires flat.

[0044] like Figure 1 and Figure 4 As shown, the vibrating screen 51 is inclined, and the height of the side closer to the washing tank 12 is higher than the height of the side farther from the washing tank 12, that is, the height of the left end is higher than the height of the right end. A feed hopper is also provided above the left end of the vibrating screen 51 to facilitate feeding waste tires after cleaning. Multiple vibrating springs 521 are also provided between the vibrating screen 51 and the vibrating frame 52, and the vibrating springs 521 are fixed above the four corners of the vibrating frame 52. The vibrating screen 51 has a material outlet 511, an impurity outlet 512, and a water outlet 513. The material outlet 511 is located at the end of the vibrating screen 51 away from the washing tank 12, the impurity outlet 512 is located on the front side of the end of the vibrating screen 51 away from the washing tank 12, and the water outlet 513 is located at the bottom of the end of the vibrating screen 51 away from the washing tank 12. After washing, some of the previously firmly stuck impurities on the waste tires may loosen. Therefore, after the washing process, the waste tires are vibrated and screened again. This time, the screen mesh size of the vibrating screen is 5-10mm. During the vibrating and screening process, some water can also be shaken out, which facilitates the subsequent drying of the waste tires.

[0045] The working principle and usage of this waste tire dust removal and cleaning equipment are as follows: Before washing the waste tires, a pre-cleaning device is set up to blow away dust and separate mud, sand and gravel. The collected waste tires are lifted and conveyed to the conveyor 32 by the lifting component 31. The lifting component 31 lifts the waste tires to a certain height and then conveys them to the conveyor 32 and they fall freely. The material discharge component 41 shakes off the mud, sand and gravel and then sends them to the washing equipment 1 for cleaning. After the washing is completed, the waste tires are further vibrated and screened by the vibration device 5 to separate the cleaned particles and fibers, which is convenient for subsequent crushing operations.

[0046] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
