Description

Technical Field

[0001] The invention relates to the technical field of dust removal, in particular to a dust collecting device in a rubber compound processing process. Background Art

[0002] Mixing is the process of mixing raw rubber or plasticized raw rubber with compounding agents into mixed rubber using a rubber mixer. It is the most important production process in rubber processing. In order to improve the physical and mechanical properties of rubber products, improve the processing and molding process, and reduce production costs, it is necessary to add various compounding agents such as fillers, reinforcing agents, accelerators and vulcanizers to the raw rubber or plastic rubber, and disperse the various compounding agents evenly to ensure the consistency of the properties of the rubber. Among them, rubber particles, fillers (such as carbon black, sulfur), and additives (such as antioxidants, accelerators) are crushed during high-speed stirring and friction. Dust will be generated during the crushing process, which not only affects the environment, but also poses a threat to the health of operators.

[0003] Nowadays, dust generated in the process of rubber compound processing is usually collected by filtering with dust bags. After a certain amount of dust is collected, the dust bag is easy to clog. When the dust bag is cleaned by air backblowing, the dust is easy to fill the inside of the treatment box and stick to the dust bag again. It takes multiple backblowing to clean it up. When the backblowing airflow is large, it is easy to cause a large impact on the dust bag, shortening the life of the dust bag. The dust bag needs to be shut down when cleaning or replacing it, which reduces production efficiency and cannot meet the needs of continuous production.

The second driving motor can drive the second rotating rod to rotate, and the gear rotation drives the first rotating rod and the cam hammer head to rotate. The cam hammer head abuts against the sliding plate, and squeezes and pushes the sliding plate downward during the rotation process. The sliding plate squeezes the rebound spring during the downward sliding process.

The high-speed airflow separates the dust inside the gap of the dust collector bag, and the cleaning is more thorough. First, most of the dust is separated from the dust collector bag by vibration, and is discharged from the ash discharge port after falling, and then the dust inside the gap of the dust collector bag is cleaned by backblowing of the airflow.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. As mentioned throughout the specification and claims, "including" is an open term, so it should be interpreted as "including but not limited to". The subsequent description of the specification is a preferred embodiment of implementing the present application, but the description is for the purpose of illustrating the general principles of the present application, and is not used to limit the scope of the present application. The scope of protection of the present application shall be determined by the definition of the attached claims.

[0038] like Figure 1-3As shown, a dust collection device in the process of mixing rubber comprises a first processing box 1, a second processing box 2 and an air inlet pipe 3. The structure of the second processing box 2 is the same as that of the first processing box 1. The air inlet pipe 3 is arranged between the first processing box 1 and the second processing box 2. One side of the air inlet pipe 3 is connected with the interior of the first processing box 1 through an air inlet channel 31. A dust removal air inlet port 32 is fixedly connected to the front end of the air inlet pipe 3. The opening of the dust removal air inlet port 32 is arranged downward. The dust generated in the process of mixing rubber enters the air inlet pipe 3 through the dust removal air inlet port 32, and enters the interior of the first processing box 1 through the air inlet channel 31 for filtering and collection. A dust collecting hopper 11 is arranged at the lower end of the first processing box 1. A dust discharge port 12 is opened at the lower end of the ash collecting hopper 11. The dust discharge port 12 is used to discharge the filtered dust. The interior of the first processing box 1 is divided into a plurality of dust removal chambers 13 by partitions. The internal airflow is combed by setting a plurality of dust removal chambers 13. The plurality of partitions will also slow down the airflow speed. The dust particles will fall and be discharged through the ash discharge port 12. A plurality of dust bag components 4 are arranged inside the dust removal chambers 13, and the dust in the airflow is filtered by the dust bag components 4. A sliding plate 5 is arranged on the top of the dust removal chamber 13. The sliding plate 5 is rectangular and slidably connected to the inner wall of the first processing box 1. Fixed blocks 51 are arranged at the four corners below the sliding plate 5. The fixed block 51 is fixedly connected to the inner wall of the dust removal chamber 13. A rebound spring 52 is arranged between the sliding plate 5 and the fixed block 51. In the process of the sliding plate 5 moving downward under force, the rebound spring 52 is compressed. After the sliding plate 5 is not under force, the rebound spring 52 rebounds and pushes the sliding plate 5 upward. The top of the dust bag component 4 is fixedly connected with a fixing plate 6, and the fixing plate 6 is fixedly connected to the inner wall of the first processing box 1. The surface of the fixing plate 6 is provided with a through hole corresponding to the dust bag component 4, and the clean air filtered by the dust bag component 4 is ejected through the through holes on the fixing plate 6.

[0039] Among them, a lifting plate 7 is arranged above the fixed plate 6, and the lifting plate 7 is slidably connected to the inner wall of the first processing box 1, and a sleeve 71 is fixedly connected to the bottom of the lifting plate 7, and the sleeve 71 is arranged corresponding to the bag dust removal component 4. A buffer spring 72 is arranged at the lower end of the sleeve 71, and an air jet 73 is arranged below the lifting plate 7. The upper end of the air jet 73 extends to the inside of the sleeve 71 and is slidably connected to the inner wall of the sleeve 71. A hydraulic cylinder 9 is fixedly installed on the top of the first processing box 1, and the output end of the hydraulic cylinder 9 is fixedly connected to the surface of the lifting plate 7. The hydraulic cylinder 9 can be extended to drive the lifting plate 7 to descend, and the position of the air jet 73 corresponds to the position of the through hole on the fixed plate 6. After the air jet 73 descends, it squeezes the buffer spring 72 and the upper end of the air jet 73 is retracted The air supply pipe 8 is retracted to the inside of the sleeve 71, and the buffer spring 72 applies a downward force to the jet pipe 73 to make the jet pipe 73 press against the surface of the fixed plate 6. The upper end of the sleeve 71 is connected to the air supply pipe 8. There are multiple air supply pipes 8 and they are distributed longitudinally and transversely. One end of the transversely distributed air supply pipe 8 extends to the top of the first processing box 1 and is connected to the air supply pipe 81. The other end of the air supply pipe 81 is connected to a high-pressure gas storage tank 82. An electromagnetic valve 83 is installed in the middle of the air supply pipe 81. The electromagnetic valve 83 is used to control the opening of the valve to allow high-pressure gas to enter the air supply pipe 81. The high-pressure gas is sprayed into the bag-type dust removal assembly 4 through the jet pipe 73, and the dust filtered on the outside of the bag-type dust removal assembly 4 is blown off by the high-speed airflow, so that the dust falls and is discharged and collected from the ash discharge port 12.

[0040] Please refer to Figure 4 The bag dust removal assembly 4 includes a bag fixing frame 41, a dust removal bag 42 and a telescopic bellows 43. The bag fixing frame 41 is a cylindrical frame arrangement. The dust removal bag 42 is sleeved on the outer side of the bag fixing frame 41. The bag fixing frame 41 provides support for the dust removal bag 42. When the airflow carrying dust passes through the dust removal bag 42, the airflow passes through the gap inside the dust removal bag 42, and the dust is filtered on the outer surface of the dust removal bag 42 and is ejected upward from the inside of the bag fixing frame 41 to the outside of the device. A telescopic bellows 43 is fixedly connected to one side of the bag fixing frame 41. The telescopic bellows 43 has telescopic ability. During the rising or falling process of the sliding plate 5, the telescopic bellows 43 can extend or contract to compensate for the height difference between the sliding plate 5 and the fixed plate 6, so that the filtered airflow can be discharged smoothly through the through hole on the fixed plate 6.

[0041] like Figure 5As shown, a plurality of first rotating rods 53 are arranged above the sliding plate 5, and the first rotating rods 53 are longitudinally arranged between the bag dust removal assemblies 4. A plurality of cam hammer heads 54 are fixedly connected to the peripheral side of the first rotating rod 53, and the plurality of cam hammer heads 54 are evenly distributed and abut against the upper surface of the sliding plate 5. One end of the first rotating rod 53 is rotatably connected to the inner wall of the first processing box 1, and the other end of the first rotating rod 53 extends to the outside of the first processing box 1 and is fixedly connected to a first bevel gear 55, and a second bevel gear 56 is meshed below the first bevel gear 55, and a second rotating rod 57 is fixedly connected to the middle part of the plurality of second bevel gears 56, and a protective cover 15 fixedly connected to the outer wall of 1 is arranged on the outer side of the second rotating rod 57, and both ends of the second rotating rod are rotatably connected to the inner wall of the protective cover 15 A second drive motor 58 is installed on one side of the protective cover 15, and the output end of the second drive motor 58 is fixedly connected to the second rotating rod 57. The second drive motor 58 drives the second rotating rod 57 to rotate, and drives the first rotating rod 53 to rotate through the rotation of the gear. The first rotating rod 53 drives the cam hammer head 54 to rotate, and the cam hammer head 54 abuts against the sliding plate 5, and squeezes and pushes the sliding plate 5 downward during the rotation process. The rebound spring 52 is squeezed during the downward sliding process of the sliding plate 5, and the rebound spring 52 is compressed downward. When the protruding part of the cam hammer head 54 rotates upward, the rebound spring 52 pushes the sliding plate 5 to move upward. The high-speed rotation of the cam hammer head 54 cooperates with the rebound spring 52 to make the sliding plate 5 and the bag dust removal assembly 4 vibrate up and down, and the dust filtered on the outside of the dust removal bag 42 is shaken off by vibration.

[0042] like Figure 6-7As shown, both ends of the air inlet pipe 3 are connected with an air inlet channel 31, and a plurality of air duct partition plates 33 are arranged inside the air inlet channel 31. The air inlet channel 31 is divided into a plurality of sub-channels by the air duct partition plates 33, and the sub-channels correspond to the dust removal chamber 13. The airflow carrying dust enters the interior of the device through the air inlet channel 31 for filtration. Two first driving motors 34 are installed at the rear end of the air inlet pipe 3, and a driving rod 35 is fixedly connected to the output end of the first driving motor 34. The driving rod 35 is rotatably connected to the air duct partition plate 33 and the inner wall of the air inlet channel 31. A plurality of air duct baffles 36 are fixedly connected to the surface of the driving rod 35. The size of the air duct baffles 36 is the same as the size of the sub-channel opening inside the air inlet channel 31. The first driving motor 34 can drive the driving rod 34 to rotate. 5 and the air duct baffle 36 rotate. When the first treatment box 1 and the second treatment box 2 are filtering dust, the first drive motor 34 drives the air duct baffle 36 to rotate upward and fit with the upper inner wall of the air inlet channel 31. At this time, the airflow can smoothly pass through the air inlet channel 31 to enter the first treatment box 1 and the second treatment box 2. When it is necessary to clean the dust on the surface of the dust bag 42, the first drive motor 34 can drive the air duct baffle 36 on one side to rotate to a vertical position to close the air inlet channel 31. At this time, the airflow can only enter the interior of the equipment through the air inlet channel 31 on the other side. The first treatment box 1 and the second treatment box 2 can work alternately by closing the air inlet channel 31 in turn, and the dust filtered on the surface of the dust bag 42 can be cleaned without stopping.

[0043] like Figure 8 As shown, an air outlet 14 is provided at the rear end of the first processing box 1, and the air outlet 14 is located between the fixed plate 6 and the lifting plate 7. The air outlet 14 is connected to an external fan through a pipeline. The external fan applies negative pressure to generate airflow to drive the dust into the device through the dust removal inlet 32 ​​for filtration and collection.

[0044] The principle of the present invention is as follows: the airflow carrying dust enters the air inlet duct 3 through the dust removal air inlet 32, and then enters the first treatment box 1 and the second treatment box 2 through multiple sub-channels of the air inlet channel 31. When the airflow carrying dust passes through the dust removal bag 42, the airflow passes through the gaps inside the dust removal bag 42, and the dust is filtered on the outer surface of the dust removal bag 42 and ejected upward from the inside of the bag fixing frame 41 to the outside of the device. When it is necessary to clean the dust on the surface of the dust removal bag 42, the first drive motor 34 close to the first treatment box 1 is started to drive the air duct baffle 36 to rotate to a vertical position to close the air inlet channel 31. At this time, the dust-carrying air The airflow can only enter the second processing box 2 for filtering. The second driving motor 58 installed on the first processing box 1 is started to drive the first rotating rod 53 and the cam hammer head 54 to rotate through gear transmission. The cam hammer head 54 abuts against the sliding plate 5 and squeezes and pushes the sliding plate 5 downward during the rotation process. The sliding plate 5 squeezes the rebound spring 52 during the downward sliding process. The rebound spring 52 is compressed downward. When the protruding part of the cam hammer head 54 rotates upward, the rebound spring 52 pushes the sliding plate 5 to move upward. The cam hammer head 54 rotates at a high speed and cooperates with the rebound spring 52 to make the sliding plate 5 and the bag dust removal assembly 4 vibrate up and down, and the outer side of the dust bag 42 is filtered by vibration. The dust is shaken off, and a large amount of dust is separated from the surface of the dust bag 42 and falls, and is discharged through the ash discharge port 12 for collection. The dust inside the gap of the dust bag 42 is not easy to be cleaned by the up and down vibration. At this time, the hydraulic cylinder 9 extends to drive the lifting plate 7 to descend. After the jet pipe 73 descends, it squeezes the buffer spring 72 and the upper end of the jet pipe 73 shrinks to the inside of the sleeve 71. The buffer spring 72 exerts a downward force on the jet pipe 73 to make the jet pipe 73 close to the surface of the fixed plate 6. The electromagnetic valve 83 is opened to make the high-pressure gas inside the high-pressure gas storage tank 82 flow into the gas supply pipe 81 and the gas delivery pipe 8 at a high speed, and is sprayed into the dust bag 42 through the jet pipe 73. The rapid air flow backblowing can separate the dust inside the gap of the dust bag 42, and the cleaning is more thorough. This scheme adopts the method of vibration cleaning first and then air flow backblowing. First, most of the dust is shaken off by vibration, and then the dust inside the dust bag 42 is further cleaned by air flow backblowing. It is avoided that the dust is filled in the dust removal chamber 13 and attached to the surface of the dust bag 42 again or enters the internal gap of the dust bag 42 by only air flow backblowing, resulting in a long cleaning time. In addition, the air duct baffle 36 can realize the alternating operation of the first treatment box 1 and the second treatment box 2 during dust cleaning, without stopping the machine during the cleaning process, thereby improving the dust collection efficiency.

[0045] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.
