Description

Technical Field

[0001] This application relates to the field of shoe crusher technology, and in particular to a stirring and ventilation device that prevents the adhesion of elastomer particles. Background Technology

[0002] In the footwear industry, the recycling of waste shoes is a key link in achieving resource recycling and cost control. Waste shoes are usually sent to a crusher to be crushed into elastic particles of materials such as EVA, PU, ​​and rubber, and then these particles are collected in containers for subsequent recycling.

[0003] The existing technology has the following problems: the surface of the broken elastic particles is prone to residual trace amounts of moisture. When they are statically piled up in the collection box, they will not only form clumps due to the pressure on the bottom particles and the sticky attraction between the particles, but also the closed environment of the collection box will make it difficult for the moisture to evaporate, further aggravating the adhesion problem.

[0032] Reference Figure 1 A stirring and ventilation device with anti-adhesion elastomer particle adhesion includes an anti-adhesion device 1. A crusher 2 is connected to the top of the anti-adhesion device 1. The crusher 2 physically crushes the raw material through its own crushing structure, processing the blocky and large-particle elastomer raw material into fine particles that meet the requirements of subsequent processing. This is a known technology and will not be described in detail.

[0033] The anti-adhesion device 1 is used to prevent the elastomer particles from sticking together and clumping after being crushed by the crusher 2, so as to ensure that the elastomer particles always remain in a dispersed state.

[0034] In one embodiment, reference is made to Figures 2-6 The anti-adhesion device 1 includes a frame 11, which is used for installation and connection, and mainly provides a stable installation carrier and support for other components such as the mixing tank 12.

[0035] A mixing tank 12 is fixedly supported on the inner side of the frame 11. The mixing tank 12 is fixed to the inner side of the frame 11 by welding. It is used to provide a space for the elastomer particles, and at the same time, it provides a closed environment for the installation and operation of components such as the rotating rod 15 and the stirring blade 16, so as to prevent the elastomer particles from leaking during the processing.

[0036] The bottom of the mixing tank 12 is provided with a discharge port 13, which is used to discharge the processed elastomer particles so that the particles that have completed the anti-adhesion operation can be smoothly discharged from the inside of the mixing tank 12.

[0037] A rotary joint 14 is sealed and fixed to the left side of the mixing tank 12. The rotating end of the rotary joint 14 passes through and extends into the interior of the mixing tank 12. The rotary joint 14 serves as a seal and connection, ensuring the sealing of the left side of the mixing tank 12 while providing stable rotational support for the rotating rod 15. It can also deliver external media into the tank without affecting the rotation of the rotating rod 15.

[0038] In this embodiment, the rotary joint 14 is a double-ended rotary joint, one end of which can be connected to an external air pump and the other end can be connected to an external water source, which can selectively deliver high-pressure gas or liquid medium into the rotary rod 15.

[0039] When it is necessary to seal and fix the rotary joint 14 to the left side of the mixing tank 12, first open the matching installation hole on the left side wall of the mixing tank 12 and process the annular sealing groove, and embed the nitrile rubber sealing ring in the groove; then insert the rotating end of the rotary joint 14 into the installation hole, so that the flange face fits against the outer wall of the mixing tank 12. After positioning by the positioning pin, tighten the sealing element diagonally and evenly with high-strength bolts to achieve installation and reliable sealing.

[0040] The rotating end of the rotary joint 14 is coaxially fixedly connected to a rotating rod 15, which serves to install and transmit power. On the one hand, it can receive the power transmitted by the motor 18 and drive the stirring blade 16 and the high-pressure nozzle 17 to rotate synchronously. At the same time, its internal channel can transport the medium to the high-pressure nozzle 17. On the other hand, it provides a fixed installation position for the stirring blade 16.

[0041] Stirring blades 16 are fixedly sleeved around the outer circumference of the rotating rod 15. The stirring blades 16 rotate under the drive of the rotating rod 15, stirring and turning the elastomeric particles in the mixing tank 12, so that the particles are evenly dispersed and the anti-sticking effect is improved.

[0042] The outer side of the rotating rod 15, avoiding the installation position of the stirring blade 16, has several sets of threaded holes 151 arranged in an axial array. The threaded holes 151 provide a detachable installation interface for the high-pressure nozzle 17. The connection between the high-pressure nozzle 17 and the rotating rod 15 is realized through threaded engagement, ensuring that the medium inside the rotating rod 15 can be stably delivered to the high-pressure nozzle 17.

[0043] Please refer to Figures 5-6 In this embodiment, the threaded holes 151 are arranged in five groups, with two holes in each group. They are symmetrically arranged in the upper and lower half of the radial section of the rotating rod 15, and the threaded holes 151 in the upper and lower half of the section are symmetrically installed in the axial direction of the rotating rod 15.

[0044] Five sets of threaded holes 151 are evenly distributed along the axial direction, with two symmetrical mounting positions in each set. After the high-pressure nozzle 17 is installed, the high-pressure nozzle 17 can form a uniform coverage in both the axial and circumferential directions of the rotating rod 15. The medium sprayed during the rotation can fully act on the elastic particles at different positions in the mixing tank 12.

[0045] On the other hand, the symmetrical arrangement in the circumferential and axial directions ensures that the overall weight distribution of the rotating rod 15 is uniform after the high-pressure nozzle 17 is installed. During rotation, no additional centrifugal force will be generated due to local weight imbalance, thereby ensuring the stability of the rotation of the rotating rod 15 and extending the service life of the rotating rod 15 and the motor 18.

[0046] The rotating rod 15 is detachably and sealed with a high-pressure nozzle 17 through the threaded hole 151, which sprays the medium conveyed by the rotating rod 15 out in the form of high pressure, acting on the elastic particles in the mixing tank 12. The high-pressure airflow impact breaks the adhesion structure that has been formed or is about to form between the particles, thus preventing the particles from clumping.

[0047] Furthermore, the airflow can create a flowing environment within the mixing tank 12, which can accelerate the evaporation of moisture on the surface of the elastomer particles and also serve as ventilation, reducing the risk of particle adhesion caused by residual moisture.

[0048] The rotating rod 15 is connected to a motor 18 away from the rotary joint 14. The motor 18 is fixedly installed on the right side of the mixing tank 12, and the output end of the motor 18 passes through the right side wall of the mixing tank 12 and is coaxially fixedly connected to the rotating rod 15. The motor 18 serves as a power source to provide driving force for the rotation of the rotating rod 15. Through the fixed connection between the output end and the rotating rod 15, the rotating rod 15, the stirring blade 16, and the high-pressure nozzle 17 are driven to rotate at a set speed to ensure the normal operation of the stirring and spraying.

[0049] A top cover 19 is fixedly installed on the top of the mixing tank 12, and a crusher 2 is fixedly installed on the top of the top cover 19. A feed channel that is connected to the discharge end of the crusher 2 is provided through the top of the top cover 19. The top cover 19 is used to close the top opening of the mixing tank 12 to prevent the elastomeric particles in the mixing tank 12 from splashing during the mixing process. At the same time, it provides a foundation for the installation of the crusher 2 and realizes the connection between the crusher 2 and the mixing tank 12 through the feed channel, so that the crushed particles can enter the mixing tank 12.

[0050] In one embodiment, reference is made to Figures 7-8 The high-pressure nozzle 17 includes a connector 171, which serves as a medium transfer device. It can receive the high-pressure medium transported by the internal channel of the rotating rod 15 and guide the medium to the conical head 173 at the top.

[0051] The bottom of the connector 171 is provided with a threaded head 172. The connector 171 is threadedly engaged with the threaded hole 151 through the threaded head 172. It is detachably and sealedly installed on the outside of the rotating rod 15. The through-hole setting of the threaded head 172 allows the high-pressure medium guided by the connector 171 to be transported to the conical head 173. Combined with the sealing relationship between the rotating rod 15 and the threaded hole 151, it can reduce the leakage of the medium during the transmission process and ensure that the medium is delivered at a stable pressure.

[0052] A sealing ring is fitted on the circumference of the threaded head 172. When the connector 171 is threadedly engaged with the threaded hole 151 through the threaded head 172, the sealing ring is clamped between the threaded head 172 and the rotating rod 15, realizing a detachable and sealed installation. The sealing ring can fill the gap between the threaded head 172 and the rotating rod 15, preventing the high-pressure medium from leaking from the threaded engagement and ensuring that the medium is delivered to the jet groove 174 at a stable pressure.

[0053] The top of the connector 171 is integrally formed with a conical head 173. The conical profile of the conical head 173 can effectively prevent elastomer particles from accumulating and sticking on the nozzle surface. Compared with flat or concave structures, the smooth conical surface can reduce the particle adhesion area, and the centrifugal force during rotation can help the particles slide off, reducing the risk of particles sticking to the nozzle and causing the air jet groove 174 to become blocked.

[0054] Furthermore, the conical profile can gather and divert the high-pressure medium conveyed by the threaded head 172, avoid turbulent flow of the medium, and ensure that the medium acts on the elastomer particles in the mixing tank 12 in a concentrated and directional manner.

[0055] In this embodiment, four jet grooves 174 are provided through the outer side of the conical head 173. The four jet grooves 174 can divide the high-pressure medium into four directional airflows, which are evenly distributed along the conical surface. With the rotation of the nozzle, a spraying range without obvious blind spots in the circumference can be formed, which avoids the spraying dead angle caused by fewer grooves and prevents the airflow pressure from being insufficient due to more grooves.

[0056] Meanwhile, the 174 pairs of conical cut areas of the four jet channels are moderate, which can meet the jetting efficiency while maintaining sufficient structural strength.

[0057] Among them, the jet grooves 174 are axially parallel along the conical surface of the conical head 173, and the spacing between adjacent jet grooves 174 is equal. This design allows the high-pressure medium to form a consistent and uniformly covered airflow when it is sprayed out from each groove. With the rotation of the nozzle, it can fully act on the elastomer particles in the mixing tank, avoiding blind spots due to messy distribution or uneven spacing.

[0058] In one embodiment, reference is made to Figure 9The top cover 19 includes a bottom plate 191, which is fixedly covered to the top of the mixing tank 12. The bottom plate 191 is used to seal the top opening of the mixing tank 12 to prevent the elastomer particles inside the mixing tank 12 from flying during the mixing and blowing process, and to provide a stable mounting base for the docking plate 192 and the filter screen 194.

[0059] A docking plate 192 is fixedly provided on the top left side of the base plate 191. The docking plate 192 is a transition component connecting the crusher 2 and the base plate 191. By being fixedly provided on the top left side of the base plate 191, it provides the crusher 2 with an installation platform higher than the base plate 191, which is adapted to the discharge end height of the crusher 2.

[0060] Meanwhile, it and the base plate 191 share a coaxial feed inlet 193, which can help position the installation position of the crusher 2 and ensure that the discharge end of the crusher 2 can be accurately aligned with the feed inlet 193, thus preventing the crushed particles from scattering during the conveying process.

[0061] A coaxial feed inlet 193 is provided through the bottom plate 191 and the docking plate 192. The crusher 2 is fixedly installed on the top of the docking plate 192, and the discharge end of the crusher 2 corresponds to and is connected to the feed inlet 193. The feed inlet 193 is provided through the bottom plate 191 and the docking plate 192 and is kept coaxial, so that the fine particles of elastomer crushed by the crusher 2 can pass through smoothly and fall directly into the mixing tank 12 for anti-sticking treatment.

[0062] Meanwhile, the coaxial design reduces particle retention in the channel, prevents particles from sticking and accumulating on the inner wall of the feed inlet 193, and ensures the continuity of material conveying.

[0063] A filter screen 194 is embedded on the top right side of the base plate 191. The filter screen 194 can filter dust or fine impurities generated in the mixing tank 12 due to stirring and blowing.

[0064] At the same time, it can maintain air circulation between the inside of the mixing tank 12 and the outside, help to remove excess moisture generated by the medium spraying inside the mixing tank 12, and reduce the risk of elastomer particles sticking together due to excessive humidity inside the tank.

[0065] In this embodiment, the filter screen 194 has a mesh size of 100 mesh, and the pore size of the 100 mesh filter screen is about 0.15 mm. It can filter dust and fine impurities with a particle size of less than 0.15 mm generated during the stirring and blowing process in the mixing tank 12, and prevent them from overflowing with the airflow and polluting the operating environment.

[0066] At the same time, it can effectively block incompletely broken elastomer particles with a particle size greater than 0.15mm, preventing large particles from leaking out of the filter screen 194 or getting stuck in the pores and causing blockage.

[0067] Working principle:

[0068] During operation, the blocky, large-particle elastomer raw material to be processed first enters the crusher 2 connected to the top of the anti-adhesion device 1. The crusher 2 crushes the raw material into fine particles that meet the requirements. The crushed particles fall smoothly into the mixing tank 12 supported by the frame 11 through the feed inlet 193, which is coaxially opened by the bottom plate 191 and the docking plate 192 on the top cover 19.

[0069] At this time, the double-headed rotary joint 14, which is sealed and fixed on the left side of the mixing tank 12, is connected to an external air pump. The air pump is in intermittent jet mode. The air pump intermittently delivers high-pressure gas to the interior of the coaxially connected rotating rod 15 through the rotary joint 14. At the same time, the motor 18 starts, driving the rotating rod 15, the outer stirring blade 16, and the high-pressure nozzle 17, which can be detachably installed through the threaded hole 151, to rotate synchronously. The stirring blade 16 continuously stirs and turns the particles in the tank to make them evenly dispersed. The high-pressure nozzle 17 receives the intermittent high-pressure gas delivered by the air pump and pulses it out from the four axially parallel and equally spaced jet grooves 174 of the conical head 173. When jetting, the airflow powerfully impacts and breaks the adhesion structure that has been formed or is about to be formed between the particles. The interval between spray stops can reduce the excessive disturbance of the airflow to the particles and avoid the energy waste caused by continuous jetting.

[0070] Furthermore, the conical surface of the cone head 173 can reduce the adhesion of particles to the nozzle surface, and the intermittent airflow delivered by the air pump can also accelerate the evaporation of moisture on the particle surface in stages. Together with the filter screen 194 set on the right side of the top cover 19, it can achieve rapid dehumidification when spraying and maintain ventilation when spraying stops, thus reducing the risk of adhesion caused by residual moisture when particles are stored.

[0071] The particles that have undergone anti-adhesion treatment are discharged from the discharge port 13 at the bottom of the mixing tank 12. When it is necessary to clean the inside of the mixing tank 12, the rotary joint 14 switches to an external water pump to deliver cleaning water to the rotating rod 15, which is then sprayed out through the high-pressure nozzle 17 to clean the inside of the mixing tank 12 and its components. The high-pressure nozzle 17 is detachable, and the user can disassemble the high-pressure nozzle 17 separately for cleaning.
