Rubber crusher with dust removal function

Abstract

The application provides a rubber crusher with a dust removal function, which comprises a crusher and a dust removal device. The dust removal device is formed by a bottom plate and a partition plate, and replaces a traditional open or simple cover type feeding port. When the blocky rubber is put into the crusher, the micro dust generated by the collision and the airflow disturbance caused by the falling of the material can be constrained in the groove body. Then, the first flexible air suction arm and the first dust suction cover are matched, the dust in the feeding port is efficiently collected under the action of the negative pressure formed by the fan, and the dust overflow from the feeding port to pollute the air in the workshop is greatly avoided. The dust removal holes are arranged on the side wall of the crusher corresponding to the crushing operation area. The second flexible air suction arm and the flat second dust suction cover which is sealingly attached to the dust removal hole can efficiently absorb the dust rising in the box. The dust containing airflow is collected and filtered in the whole path through the double-cavity independent conveying of the dust collecting block, the integration of the airflow of the dust collecting interface and the non-woven fabric dust collecting, so that the secondary dust raising caused by the dust with the particles in the discharging is avoided.

Description

Technical Field

[0001] This application relates to the field of crusher technology, and in particular to a rubber crusher with dust removal function. Background Technology

[0002] In the fields of rubber product manufacturing and waste rubber recycling, rubber crushers are the core equipment for rubber material pretreatment. They crush blocky and large-particle rubber into fine particles that meet the needs of recycling through physical methods such as toothed roller extrusion and hammer impact, which is of great significance for improving the recycling rate of rubber resources.

[0003] The existing technology has the following problems: The existing rubber crusher has a significant dust pollution problem during operation, which will seriously affect the workshop environment and the health of operators. Its feed port is mostly open or simple cover plate design. When the block rubber is fed in, the micro-shavings generated by the collision with the feed port and the airflow disturbance caused by the falling material will cause dust to overflow from the feed port, pollute the workshop air and increase the cleaning cost of surrounding equipment.

[0004] Furthermore, when rubber is processed by the crushing mechanism in the crushing box, it will generate a large amount of fine dust. However, existing rubber crushers only rely on partial sealing of the top feed port or bottom discharge port for processing, which causes the rising dust to escape from the gaps in the box body and also creates secondary dust with the discharge of particles.

[0013] The front ends of both the first and second dust outlets are fixedly connected to the dust collection interface.

[0014] In one embodiment, the dust collection interface includes a docking ring, the air outlet of which is sealed and coaxially connected to the air inlet of the fan.

[0037] Reference Figures 1-2A rubber crusher with dust removal function includes a crusher 1. The crusher 1 is the core execution component for crushing rubber materials. It can physically crush blocky and large-particle rubber to provide raw materials that meet the particle size requirements for subsequent rubber recycling. This is a known technology and will not be described in detail.

[0038] A dust removal device 2 is fixedly installed at the top of the crusher 1. The dust removal device 2 operates synchronously with the crushing operation of the crusher 1 to prevent dust from overflowing into the workshop environment when the crusher 1 is working. This not only protects the health of the operators, but also reduces the pollution of the crusher 1 and surrounding equipment by dust. At the same time, it ensures the cleanliness of the crushed rubber raw material and reduces the cost of cleaning impurities in subsequent processing stages.

[0039] In one embodiment, reference is made to Figures 3-4 The dust removal device 2 includes a mounting plate 21, which is used for installation and connection, providing a fixed mounting carrier for other equipment. At the same time, the mounting plate 21 can cooperate with the base plate 22 to form a protective cover, which can block some external debris from entering the device and prevent it from interfering with the operation of the equipment.

[0040] The bottom plate 22 is fixedly installed on the bottom of the mounting plate 21. The bottom plate 22 is fixedly installed on the top surface of the crusher 1. The bottom plate 22 serves as a connecting transition between the dust removal device 2 and the crusher 1. It is fixedly installed on the top surface of the crusher 1 by bolts. While it is used for installation and connection, its tail end through groove and the partition plate 23 enclose the feed chute 24, which guides the raw material feed and restricts the spread range of the feed dust.

[0041] A partition 23 is fixedly installed in the middle of the top of the base plate 22. The partition 23 is used to clearly divide the top space of the base plate 22 into two functional areas: the feeding operation area and the dust collection component installation area. This can effectively prevent the dust generated when the rubber raw material is fed into the system from directly spreading to the surface of components such as the dust collection block 25 and the fan 29, thereby reducing dust pollution to these core components and reducing the frequency of equipment maintenance.

[0042] Meanwhile, the through groove of the partition plate 23 and the bottom plate 22 forms the feed trough 24. Its structure can not only guide the rubber raw material to fall accurately into the feed port of the crusher 1 and prevent the raw material from spilling, but also confine the dust generated during the feeding process to the internal space of the feed trough 24 to prevent the dust from spreading to the surroundings, which facilitates the subsequent dust removal operation of the first flexible suction arm 26 and greatly improves the dust collection efficiency of the feeding process.

[0043] Furthermore, the partition plate 23 is fixedly connected to the left and right end walls of the inner side of the mounting plate 21. The bottom plate 22 has a through groove at the top end corresponding to the feed inlet of the crusher 1, and together with the partition plate 23, it forms a feed trough that communicates with the feed inlet of the crusher. The feed trough 24 provides a channel for rubber raw materials to be fed from the outside to the feed inlet of the crusher 1, ensuring that blocky and granular rubber raw materials can enter the interior of the crusher 1 accurately and smoothly, and preventing the raw materials from spilling to the outside of the crusher 1 during the feeding process.

[0044] Meanwhile, the enclosed structure of the feed trough 24 can seal the dust generated when the raw materials are fed into the trough, preventing the dust from spreading directly into the workshop environment. At the same time, the relatively closed space formed by the trough allows the dust to accumulate inside temporarily, which facilitates the first flexible suction arm 26 to perform dust removal operations, greatly improving the dust collection efficiency of the feeding process.

[0045] A dust collection block 25 is fixedly installed at the top front end of the base plate 22. The dust collection block 25 is used to collect and divert dust. It is sealed and connected to the first flexible suction arm 26, the second flexible suction arm 27, and the dust collection interface 28 through multiple interfaces, which can concentrate the dust sucked up by the two suction arms.

[0046] The top of the dust collection block 25 is connected to a first flexible suction arm 26. The suction port of the first flexible suction arm 26 passes through the top front end of the partition 23 and is suspended at the top of the feed trough 24. The first flexible suction arm 26 is used to collect dust in the feed trough 24 area. Due to its own characteristics, the first flexible suction arm 26 can flexibly adjust the suspension angle and height of the suction port according to the actual operation, ensuring that the suction port is always accurately aimed at the area with the highest dust concentration in the feed trough 24, so as to achieve high-efficiency dust capture and minimize the escape of dust from the top of the feed trough 24.

[0047] The right side of the dust collection block 25 is connected to a second flexible suction arm 27. The suction port of the second flexible suction arm 27 passes through the front end of the inner side wall of the mounting plate 21 and is fixedly installed on the side wall of the crusher 1. During the operation of the crusher 1, some dust will escape from the gaps or reserved openings in the side wall of the crusher 1. The suction port of the second flexible suction arm 27 can clean up the escaped dust in time, fill the dust blind spot of the first flexible suction arm 26 which only covers the feeding area, and realize the all-round dust collection of the crusher 1.

[0048] Meanwhile, the second flexible suction arm 27 is the same as the first flexible suction arm 26. With its own characteristics, it can adjust its bending angle according to the changes in the dust emission position under different crushing conditions, so as to ensure that the suction port is always closely attached to the dust emission area and improve the dust collection efficiency.

[0049] The dust collection block 25 is fixedly connected to a dust collection interface 28 at its front end. The dust collection interface 28 is used to integrate the dual-path dust-laden airflow output by the dust collection block 25 into a single, stable airflow, so as to avoid the convergence and turbulence of multiple airflows before entering the fan 29, reduce pressure loss, and ensure that the airflow can smoothly enter the fan 29.

[0050] A fan 29 is connected to the outlet of the dust collection interface 28. The inlet of the fan 29 is connected to the outlet of the dust collection interface 28. The fan 29 drives the impeller to rotate at high speed through its own motor, creating a continuous and stable negative pressure environment. Under the action of negative pressure, the dust in the feed trough 24 is sucked into the first flexible suction arm 26, and the dust on the side wall of the crusher 1 is sucked into the second flexible suction arm 27. After being collected by the dust collection block 25 and transferred through the dust collection interface 28, the dust is finally pushed to the dust collection bag 291 for filtration and separation.

[0051] In this embodiment, the fan 29 has a power of 1.5KW, which is sufficient to meet the dust collection requirements and, due to its moderate negative pressure, will not suck out the broken rubber particles.

[0052] The air outlet extends through the top front end of the base plate 22 and is connected to a dust collection bag 291. The dust collection bag 291 is used to collect the dust-laden airflow discharged by the fan 29. Its own filter material allows air in the airflow to pass through, while intercepting rubber dust particles in the airflow inside the bag, preventing dust from being discharged into the workshop environment with the airflow and causing secondary pollution.

[0053] In this embodiment, the partition 23 is inclined, with its inclined end tilted towards the feed trough 24 at an angle of 30°. The 30° angle can guide the dust in the feed trough 24 to gather towards the suction port of the first flexible suction arm 26, thereby improving the dust collection efficiency, and can also reduce the resistance when the rubber raw material falls, thus preventing the raw material from accumulating and getting stuck.

[0054] Among them, the dust collection bag 291 is made of breathable and wear-resistant non-woven fabric. The dust collection bag 291 made of non-woven fabric can not only allow clean airflow to pass through smoothly, but also effectively intercept rubber dust. At the same time, the wear-resistant properties can extend the service life of the dust collection bag 291.

[0055] Furthermore, the connection between the dust collection bag 291 and the air outlet of the fan 29 is equipped with an elastic sealing ring. The elastic sealing ring can tightly fit the connection gap and prevent dust from leaking from the interface.

[0056] Among them, the outer sides of the first flexible suction arm 26 and the second flexible suction arm 27 are both fitted with metal shaping hoses. The metal shaping hoses can provide stable support for the flexible suction arms and prevent them from deforming under negative pressure.

[0057] Furthermore, the bending angle range of the metal-shaped flexible hose is 0°-180°. This bending range can flexibly adapt to the dust dispersion location, and after adjustment, it can maintain a fixed angle to ensure that the air intake is accurately aligned with the dust-ingress area.

[0058] In one embodiment, reference is made to Figure 2 The side wall of the crusher 1 is provided with a dust removal hole 11. The location of the dust removal hole 11 corresponds to the crushing operation area inside the crusher 1. A filter screen is fixedly installed inside the dust removal hole 11.

[0059] The dust removal hole 11 is located directly in line with the crushing operation area inside the crusher, allowing the air intake of the second flexible suction arm 27 to directly act on the dust emission point through the hole, thereby improving the dust removal efficiency. The filter screen can intercept the fine rubber particles generated by crushing, preventing them from entering the suction arm and causing blockage, while also preventing particles from wearing down the fan 29 components with the airflow.

[0060] In one embodiment, reference is made to Figure 4 The first flexible suction arm 26 has a first dust suction hood 261 connected to its suction port end, and the second flexible suction arm 27 has a second dust suction hood 271 connected to its suction port end.

[0061] The first dust hood 261 has a trumpet-shaped structure with its opening facing the dust diffusion area at the top of the feed trough 24. The trumpet-shaped first dust hood 261 can expand the dust collection coverage area, gather the dust dispersed and rising in the feed trough 24 more comprehensively to the air intake, prevent dust from escaping from the edge of the dust collection area, and improve the dust collection efficiency of the feed area.

[0062] The second dust suction hood 271 has a flat structure, and its opening is sealed and fitted with the dust removal hole 11 on the side wall of the crusher 1. The flat structure of the second dust suction hood 271 can be closely fitted to the dust removal hole 11, reducing the gap between the dust suction port and the dust removal hole, ensuring that all the dust escaping from inside the crusher 1 enters the second dust suction hood 271 through the dust removal hole 11, and preventing dust from overflowing from the fitting gap.

[0063] In this embodiment, the second dust hood 271 adopts a flat structure with a diameter of 100mm and a thickness of 15mm. A 3mm thick oil-resistant rubber sealing gasket is pasted on the edge of its opening. The opening of the dust hood is tightly fixed to the side wall of the crusher 1 where the dust removal hole 11 is located by bolts, so that the sealing gasket completely fits the side wall surface and achieves a gapless seal.

[0064] In one embodiment, reference is made to Figure 5 The dust collection block 25 includes a housing 251, the bottom of which is fixedly installed on the top front end of the base plate 22. The housing 251 is used for installation and connection, and provides stable protection for the internal cavity to prevent dust from being disturbed by external factors or leaking during the conveying process.

[0065] The outer shell 251 is internally divided into a first cavity 252 and a second cavity 253, and the first cavity 252 and the second cavity 253 are not connected to each other. Through the first cavity 252 and the second cavity 253, dual-path dust independent conveying can be realized, preventing the dust collected by the first flexible suction arm 26 from the feed trough 24 from mixing and colliding with the dust collected by the second flexible suction arm 27 from the side wall of the crusher 1, and avoiding dust blockage or reduced conveying efficiency caused by airflow turbulence.

[0066] In this embodiment, the outer shell 251 is divided into a first cavity 252 and a second cavity 253 by a vertical partition plate 258 fixedly installed inside.

[0067] A first dust inlet 254 is provided through the right side wall of the outer shell 251 corresponding to the air outlet end of the second flexible suction arm 27, and a first dust outlet 255 is provided through the front right side wall of the outer shell 251. Both the first dust inlet 254 and the first dust outlet 255 are connected to the first cavity 252.

[0068] The top wall of the outer shell 251 is provided with a second dust inlet 256 through the air outlet end of the first flexible suction arm 26, and the left side wall of the front end of the outer shell 251 is provided with a second dust outlet 257 through the air outlet. Both the second dust inlet 256 and the second dust outlet 257 are connected to the second cavity 253.

[0069] The front ends of the first dust outlet 255 and the second dust outlet 257 are both fixedly connected to the dust collection interface 28;

[0070] The first dust inlet 254 and the second dust inlet 256 ensure that the two dust sources can smoothly enter the corresponding cavities, while the first dust outlet 255 and the second dust outlet 257 collect the dust in the independent cavities to the dust collection interface 28.

[0071] In one embodiment, reference is made to Figure 6 The dust collection interface 28 includes a docking ring 281, which is used for installation and connection. The air outlet end of the docking ring 281 is sealed and coaxially connected with the air inlet end of the fan 29.

[0072] When the outlet end of the docking ring 281 is connected to the inlet end of the fan 29, an elastic sealing gasket is placed between the two mating surfaces to fill any possible small gaps; then the bolts are used to fasten the docking ring 281 to the flange of the inlet end of the fan 29, pressing the sealing gasket to achieve a leak-free sealed connection.

[0073] The air inlet end of the docking ring 281 is fixedly connected to a three-way pipe 282. The three-way pipe 282 is used to combine the two dust-laden airflows output from the first dust inlet 254 and the second dust inlet 256 of the dust collection block 25 into a single airflow and deliver it to the docking ring 281.

[0074] The two branch air inlet ends of the three-way pipe 282 are respectively fixedly connected to the first connector 283 and the second connector 284. The end of the first connector 283 away from the three-way pipe 282 is sealed and connected to the front end of the first dust outlet 255 of the dust collection block 25. The end of the second connector 284 away from the three-way pipe 282 is sealed and connected to the front end of the second dust outlet 257 of the dust collection block 25.

[0075] The first connector 283 and the second connector 284 are used for docking. They serve as transition connectors to adapt to the size differences between the first dust outlet 255, the second dust outlet 257, and the branch end of the tee pipe 282.

[0076] Working principle:

[0077] During operation, the crusher 1 first physically crushes the blocky and large-particle rubber, while the fan 29 with a power set to 1.5kW starts synchronously, and the impeller is driven by the motor to rotate at high speed to form a continuous and stable negative pressure environment.

[0078] The operator puts the rubber raw material into the feed trough 24 formed by the bottom plate 22 and the partition plate 23. The raw material falls smoothly into the feed inlet of the crusher 1 along the partition plate 23 which is inclined at 30°. The dust generated during the feeding process is confined in the feed trough 24. At this time, the metal shaped hose on the outside of the first flexible suction arm 26 supports it to maintain a fixed angle, so that the trumpet-shaped first dust suction hood 261 at the suction port end is accurately aligned with the dust diffusion area at the top of the feed trough 24. Under the action of negative pressure, the dust is sucked in. Then the dust enters the second cavity 253 inside the outer shell 251 of the dust collection block 25 through the first flexible suction arm 26.

[0079] Meanwhile, the dust generated in the crushing operation area inside the crusher 1 is dispersed outward through the dust removal holes 11 corresponding to the side wall. The metal shaped hose on the outside of the second flexible suction arm 27 is adjusted to fit the angle of the dust removal hole 11, so that the flat second dust suction hood 271 sucks in the dust. The dust enters the first cavity 252 of the dust collection block 25 through the second flexible suction arm 27. At the same time, the filter screen installed in the dust removal hole 11 will intercept fine rubber particles to prevent clogging.

[0080] Two dust streams are transported to the first dust outlet 255 and the second dust outlet 257 respectively in independent cavities. They then enter the three-way pipe 282 of the dust collection interface 28 through the first connector 283 and the second connector 284. After being combined into a single airflow, the airflow enters the fan 29 through the docking ring 281. Finally, the fan 29 pushes the dust-laden airflow to the dust collection bag 291. The breathable and wear-resistant non-woven fabric dust collection bag 291 intercepts the dust, and the clean airflow passes through the dust collection bag 291 and is discharged, completing the entire dust removal process.
