Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rubber products, especially a rubber powder static electricity removing device. BACKGROUND

[0002] In the rubber product processing industry, rubber powder is widely used as a key raw material, and its production and subsequent processing procedures are extremely complex. Rubber powder is usually made through a series of fine processes such as waste rubber product recycling and crushing, grinding, etc. These processes inevitably cause the rubber powder to carry static electricity.

[0003] Rubber powder can be obtained in various ways. Whether it is waste rubber tires, conveyor belts, or various industrial rubber products, after mechanical processing such as crushing and grinding, the rubber powder particles rub at high speed and collide violently inside the equipment, and static electricity is thus generated in large quantities. In particular, during the use of rubber powder, such as when unloading into key processing containers such as premix tanks and reaction kettles, the static electricity problem becomes more prominent. Once static discharge occurs, the instantaneous electric spark energy is enough to ignite the rubber powder, which in turn induces a spontaneous combustion accident.

[0004] Currently, a representative method is to introduce nitrogen gas into the premix tank to isolate air. Nitrogen gas is stable in nature and does not easily react with rubber powder. In theory, by exhausting the air in the tank, the necessary condition for rubber powder combustion can be cut off, achieving the purpose of fire prevention.

[0005] In view of the above related technology, although isolating air can reduce the probability of rubber powder combustion, in order to ensure that nitrogen gas can effectively isolate air and prevent oxygen from entering, the sealing requirement of the equipment is extremely high. The premix tank and other containers need to use high-quality sealing materials and complex sealing structures, which increases the use cost of the equipment. At the same time, the static electricity carried by the rubber powder is still accumulating, and the risk of spontaneous combustion caused by static discharge is always present, which cannot be completely eliminated, and there is still a safety risk in the production process. UTILITY MODEL CONTENTS

[0006] In order to improve the safety of rubber powder during the feeding process and reduce the use cost of the equipment, the utility model provides a rubber powder static electricity removing device.

[0007] The utility model provides a rubber powder static electricity removing device, adopts the following technical scheme:

[0008] A rubber powder static electricity removing device, comprising a machine body, a feeding pipe and a static electricity removing mechanism, the discharge end of the feeding pipe is in communication with the inside of the machine body, and the other end of the feeding pipe is in communication with a feeding device;

[0009] The static electricity removing mechanism comprises a fixed plate, a vent pipe and a sprayer, one end of the fixed plate is fixed in the body, and the fixed plate is located at one end of the body close to the feeding pipe, the sprayer is fixed on the fixed plate, one end of the vent pipe is communicated with the sprayer, and the other end of the vent pipe is communicated with a gas source.

[0010] By using the above technical scheme, in the process of feeding rubber powder, high-pressure steam is introduced through the vent pipe, and the steam is sprayed on the rubber powder through multiple sprayers to eliminate static electricity between the rubber powder; the sprayers are arranged in a circumferential direction, which can quickly and uniformly cover the entire feeding area, so that the rubber powder entering the body can be fully treated, thereby greatly reducing the problem of dust aggregation or adhesion caused by static electricity.

[0011] Optionally, the static electricity removing mechanism further comprises a lifting assembly, the lifting assembly comprises a telescopic cylinder, one end of the telescopic cylinder is fixed in the body, and the telescopic cylinder is located at one end of the body close to the feeding pipe; the fixed plate is fixedly arranged on the telescopic rod of the telescopic cylinder.

[0012] By using the above technical scheme, the telescopic cylinder is applied to make the fixed plate and the sprayer thereon move in a vertical direction, so that the spraying height can be flexibly adjusted according to the actual feeding amount, the height of the feeding port of the feeding pipe or the state of the rubber powder. This flexibility ensures that the steam can act more accurately on the target area, improving the static electricity removing effect; for different types, particle sizes or humidity of the rubber powder, the distance between the sprayer and the material can be changed by adjusting the position of the telescopic cylinder to adapt to the best processing parameters under various working conditions.

[0013] Optionally, the lifting assembly further comprises a distance sensor, the distance sensor is arranged on the fixed plate, and the distance sensor is electrically connected with the telescopic cylinder.

[0014] By using the above technical scheme, the distance sensor can measure the distance between the fixed plate (and the sprayer thereon) and the surface of the material in real time, and feed back the information to the control system. This enables the system to automatically adjust the action of the telescopic cylinder according to the actual distance, ensuring that the sprayer is always in the best working position.

[0015] Optionally, the sprayer comprises multiple spray heads and a main body, the main body is fixedly connected with the fixed plate, the spray heads are arranged on the main body in an axial direction of the main body, a spray port is formed in the spray head, the spray port is communicated with a flow guide hole in the main body, and the main body is connected with the vent pipe.

[0016] By adopting the above technical solution, when steam is injected, the steam enters the main body through the steam pipe, and the main body distributes the steam evenly to each injection head. The steam is then ejected through the injection port to remove static electricity from the rubber powder.

[0017] Optionally, the injector further includes a baffle and an elastic element, one end of the elastic element being fixedly connected to the injection head, and the other end of the elastic element being fixedly connected to the baffle.

[0018] By adopting the above technical solution, during the steam injection process, high-pressure steam pushes the baffle to move, and the baffle compresses the elastic element to achieve stable steam injection. This ensures that when the steam pressure is unstable, steam is only injected when the injection pressure of multiple injectors exceeds the pressure exerted on the baffle by the elastic element, reducing the possibility of unstable and uneven steam pressure from multiple injectors. At the same time, when the machine stops, steam injection stops, and the elastic element pushes the baffle back to seal the injection port of the injector, reducing the possibility of rubber dust entering the injector and reducing the possibility of the injector becoming clogged.

[0019] Optionally, the injector further includes a guide rod, a support ring, and a retaining plate. One end of the support ring is fixedly connected to the injection head, and the other end of the support ring is fixedly connected to the guide rod. The baffle is slidably disposed on the guide rod, and the retaining plate is disposed on the injection head.

[0020] By adopting the above technical solution, the baffle can slide on the guide rod during the steam injection process, reducing the possibility of the baffle deflecting to the side. If deflection occurs, it may lead to unstable steam injection pressure and disordered injection direction, thus improving the stability of steam injection. When the baffle contacts the clamping plate, it can better seal the injector and reduce the possibility of rubber powder entering the vent pipe.

[0021] Optionally, the injector further includes a locking block disposed on the guide rod.

[0022] By adopting the above technical solution, during the steam injection process, if the steam injection pressure gradually increases, the baffle and the blocking block will abut against each other, preventing the baffle from continuing to move closer to the injection head and reducing the possibility of the baffle clogging the injection head.

[0023] Optionally, multiple injectors are arranged along the axial direction of the feeding pipe, and adjacent main bodies are fixedly connected to each other.

[0024] By adopting the above technical solution, multiple injectors increase the volume of steam injected in the axial direction, thereby increasing the travel range of the rubber powder in contact with the steam during its fall, and thus enabling the rubber powder to come into more full contact with the steam, improving the static electricity removal effect.

[0025] Optionally, the static elimination mechanism further includes a one-way valve, which is disposed on the vent pipe.

[0026] By adopting the above technical solution, the main function of the one-way valve during the steam injection process is to prevent materials or other media from flowing back into the feeding system or equipment during the steam injection process; the pressure during the steam injection process will not fluctuate due to the backflow of materials, thereby maintaining the consistency of the injection effect.

[0027] Optionally, the static elimination mechanism further includes a water-cutting valve and a pressure sensor. The water-cutting valve is disposed on the vent pipe and is electrically connected to the pressure sensor.

[0028] By adopting the above technical solutions, the water-cutting valve can effectively remove moisture, ensuring that the material dryness meets the standards and improving product quality; the pressure sensor can monitor the pressure changes in the vent pipe in real time, providing necessary feedback information to the automated control system. This allows operators to adjust parameters according to actual needs to achieve optimal operating conditions.

[0029] In summary, this utility model has at least one of the following beneficial technical effects:

[0030] 1. By setting up an anti-static mechanism and sprayer, the entire feeding area can be quickly and evenly covered, ensuring that all rubber powder entering the machine can be fully processed, thereby greatly reducing the problem of dust accumulation or sticking caused by static electricity.

[0031] 2. By setting up a lifting assembly and adjusting the position of the telescopic cylinder, the distance between the injector and the material can be changed to adapt to the optimal processing parameters under various working conditions.

[0032] 3. By setting baffles and elastic components, the possibility of unstable and uneven steam pressure from multiple injectors is reduced, thus reducing the possibility of injector blockage. Attached Figure Description

[0042] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.

[0043] This utility model discloses a device for removing static electricity from adhesive powder. (See attached diagram.) Figure 1 A kind of glue powder antistatic device mainly includes a body 100, a feeding mechanism, an antistatic mechanism 300 and a stirring mechanism 500. The stirring mechanism 500 is installed inside the body 100. The feeding mechanism includes a feeding pipe 200. The discharge end of the feeding pipe 200 is connected to the inside of the body 100, and the other end of the feeding pipe 200 is connected to the feeding device.

[0044] The static elimination mechanism 300 includes a fixed plate 310, a vent pipe 320, and an ejector 330. One end of the fixed plate 310 is fixed inside the machine body 100, and the fixed plate 310 is located at the end of the machine body 100 near the feeding pipe 200. One or more ejectors 330 are provided. In this example, multiple ejectors 330 are evenly distributed and fixed on the fixed plate 310 along the circumference of the feeding pipe 200. One end of the vent pipe 320 is connected to the ejector 330, and the other end of the vent pipe 320 is connected to the air source. The ejector 330 includes a spray head 331, and a spray port 332 is opened on the spray head 331.

[0045] During the rubber powder feeding process, high-pressure steam is introduced through the vent pipe 320. The steam is sprayed onto the rubber powder through multiple injectors 330 to eliminate static electricity between the rubber powder particles. The circumferentially arranged injectors 330 can quickly and evenly cover the entire feeding area, ensuring that all rubber powder entering the machine body 100 is fully processed, thereby greatly reducing the problem of dust accumulation or adhesion caused by static electricity.

[0046] In some embodiments, the static eliminator 300 may further include a lifting assembly 340, which includes a telescopic cylinder 341. One end of the telescopic cylinder 341 is fixed inside the machine body 100, and the telescopic cylinder 341 is located at the end of the machine body 100 near the feeding pipe 200. A fixing plate 310 is fixedly mounted on the telescopic rod of the telescopic cylinder 341. The application of the telescopic cylinder 341 allows the fixing plate 310 and its ejector 330 to move vertically, thereby flexibly adjusting the spray height according to the actual feeding amount, the feeding port height of the feeding pipe 200, or the state of the rubber powder. This flexibility ensures that the steam can act more precisely on the target area, improving the static eliminator effect. For rubber powders of different types, particle sizes, or moisture content, the distance between the ejector 330 and the material can be changed by adjusting the position of the telescopic cylinder 341 to adapt to the optimal processing parameters under various working conditions.

[0047] In some embodiments, the lifting assembly 340 further includes a distance sensor 342, which is mounted on the fixed plate 310 and electrically connected to the telescopic cylinder 341. The distance sensor 342 can measure the distance between the fixed plate 310 (and the ejector 330 thereon) and the material surface in real time and feed this information back to the control system. This allows the system to automatically adjust the movement of the telescopic cylinder 341 according to the actual distance, ensuring that the ejector 330 is always in the optimal working position.

[0048] In some embodiments, the injector 330 further includes a baffle 333 and an elastic element 334. One end of the elastic element 334 is fixedly connected to the injection head 331, and the other end of the elastic element 334 is fixedly connected to the baffle 333. During steam injection, high-pressure steam pushes the baffle 333 to move, and the baffle 333 compresses the elastic element 334 to achieve stable steam injection. This ensures that when the steam pressure is unstable, and the injection pressure of multiple injection heads 331 exceeds the pressure exerted by the elastic element 334 on the baffle 333, steam is only injected, reducing the possibility of unstable and uneven steam pressure from multiple injectors 330. Simultaneously, when the machine stops, steam injection ceases, and the elastic element 334 pushes the baffle 333 back, sealing the injection port 332 of the injection head 331, reducing the possibility of rubber dust entering the injector 330 and reducing the possibility of blockage in the injector 330.

[0049] In some embodiments, the injector 330 further includes a guide rod 335, a support ring 336, and a retaining plate 337. One end of the support ring 336 is fixedly connected to the injection head 331, and the other end of the support ring 336 is fixedly connected to the guide rod 335. A baffle 333 is slidably disposed on the guide rod 335, and the retaining plate 337 is disposed on the injection head 331. During steam injection, the baffle 333 can slide on the guide rod 335, reducing the possibility of lateral deviation of the baffle 333. If lateral deviation occurs, it may lead to unstable steam injection pressure and disordered injection direction, thus improving the stability of steam injection. When the baffle 333 contacts the retaining plate 337, it can better seal the injector 330, reducing the possibility of rubber powder entering the vent pipe 320.

[0050] In some embodiments, the injector 330 further includes a locking block 338 disposed on the guide rod 335. During steam injection, if the steam injection pressure gradually increases, the baffle 333 abuts against the locking block 338, preventing the baffle 333 from continuing to approach the injector head 331, thus reducing the possibility of the baffle 333 clogging the injector head 331.

[0051] In some embodiments, multiple ejectors 330 are arranged along the axial direction of the feeding pipe 200, and adjacent bodies 339 are fixedly connected to each other. The multiple ejectors 330 increase the volume of ejected steam in the axial direction, thereby increasing the travel range of the rubber powder in contact with the steam during its fall, and thus enabling the rubber powder to have more sufficient contact with the steam, improving the static elimination effect.

[0052] In some embodiments, the feeding mechanism further includes a one-way valve 350, which is disposed on the feeding pipe 200. During the steam injection process, the main function of the one-way valve 350 is to prevent material or other media from flowing back into the feeding system or equipment during the steam injection process; the pressure during the steam injection process will not fluctuate due to the backflow of material, thereby maintaining the consistency of the injection effect.

[0053] In some embodiments, the feeding mechanism further includes a water-cutting valve 360 ​​and a pressure sensor 370. The water-cutting valve 360 ​​is disposed on the feeding pipe 200, and the water-cutting valve 360 ​​is electrically connected to the pressure sensor 370. The water-cutting valve 360 ​​effectively removes moisture, ensuring that the material dryness meets the standards and improving product quality. The pressure sensor 370 can monitor the pressure changes within the feeding pipe 200 in real time, providing necessary feedback information to the automated control system. This allows operators to adjust parameters according to actual needs to achieve optimal operating conditions.

[0054] In some embodiments, the machine body 100 is further provided with a controller 400, which is electrically connected to a pressure sensor 370 and a distance sensor 342. By receiving the signal from the pressure sensor 370, the controller 400 can monitor the pressure status inside the feeding pipe 200 in real time to ensure that the operation is within a safe range. The information provided by the distance sensor 342 can help the controller 400 accurately grasp the relative position between materials or equipment. Based on the information fed back by the distance sensor 342 and the pressure sensor 370, the controller 400 can automatically adjust relevant parameters (such as valve opening) to maintain optimal working conditions and reduce manual intervention. When an abnormal situation is detected, the controller 400 can react quickly, such as issuing an alarm or taking preventive measures to prevent the problem from escalating.

[0055] In some embodiments, multiple ejectors 330 are arranged along the axial direction of the feeding pipe 200, and adjacent bodies 339 are fixedly connected to each other. The multiple ejectors 330 increase the volume of ejected steam in the axial direction, thereby increasing the travel range of the rubber powder in contact with the steam during its fall, and thus enabling the rubber powder to have more sufficient contact with the steam, improving the static elimination effect.

[0056] The implementation principle of the static eliminator for adhesive powder in this embodiment of the utility model is as follows:

[0057] By incorporating an antistatic mechanism 300, the ejector 330 can quickly and evenly cover the entire feeding area, ensuring that all rubber powder entering the machine body 100 is fully processed, effectively reducing dust accumulation or adhesion caused by static electricity. Simultaneously, the equipped lifting assembly 340 can optimize the distance between the ejector 330 and the material by adjusting the position of the telescopic cylinder 341, ensuring optimal processing results under different operating conditions. Furthermore, the introduction of baffles 333 and elastic elements 334 not only reduces the risk of unstable steam pressure when multiple ejectors 330 are spraying, but also reduces the possibility of ejector 330 clogging. In summary, these designs work together to improve the system's stability and efficiency, ensuring smooth processing.

[0058] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
