Description

Technical Field

[0001] This invention relates to the field of pulverizing technology, and more specifically to a pulverizing device for recovering the shell of a concentrator. Background Technology

[0002] The concentrator is the central management and control device of a remote centralized meter reading system. It is responsible for functions such as periodically reading terminal data, transmitting system commands, data communication, network management, event logging, and horizontal data transmission. The concentrator's casing is generally made of ABS plastic. The waste plastic casing needs to be shredded during the recycling process, and the shredded plastic casing can be recycled, saving energy and protecting the environment.

[0003] Plastic molecules are stable and not easily degraded by the natural environment; crushing can accelerate their decomposition and reuse. Furthermore, crushed plastics are easier to recycle and reuse, contributing to resource conservation and environmental protection. Crushing is necessary for better subsequent processing and handling of plastics. The crushing process of ABS plastic generates plastic dust. If inhaled, especially through the respiratory tract into the alveoli, long-term accumulation can lead to silicosis. Moreover, if plastic dust is continuous or frequent, and the quantity is sufficient to form a flammable mixture with air, it may cause an explosion, posing a threat to personnel and equipment safety. To address these technical problems, it is necessary to provide a crushing device for concentrator shell recycling. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a pulverizing device for concentrator shell recycling, which can effectively solve the problems in the prior art where plastic dust is generated during the pulverization of ABS plastic, which may lead to silicosis due to long-term accumulation. In addition, if plastic dust occurs continuously or frequently and the amount is sufficient to form a mixture of combustible dust and air, it may cause an explosion, posing a threat to the safety of personnel and equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a pulverizing device for recycling concentrator shells, comprising: The pulverizer body has a feed inlet on its side and a working chamber at its bottom. The recycling section is located in the space enclosed by the working chamber. The recycling section includes a frame, the bottom of which is fixedly installed below the crusher body. A recycling bin is rotatably connected inside the frame. The outer surface of the recycling bin is fitted with a filter element, and the top of the filter element is connected to the outlet of the crusher body through a feed pipe.

[0006] Furthermore, the recycling bin adopts a hemispherical design, and the opening of the recycling bin faces upward. The recycling bin is magnetically connected to a closing plate through a discharge port located below it. The closing plate and the recycling bin can be connected by a threaded assembly.

[0007] Furthermore, the recycling bin is rotatably connected to a shaft via a bushing on its upper surface. There are two shafts symmetrically distributed on the upper surface of the recycling bin. A rigid rod is fixedly connected between adjacent surfaces of a pair of shafts. The end of the shaft away from the rigid rod is rotatably connected to the inside of the frame.

[0008] Furthermore, a drive housing is fixedly connected to the outer surface of the frame via a mounting bracket. The drive housing is connected to the shaft via a transmission connection. A scraper that fits against the inner wall of the recycling bin is fixedly connected to the side of the shaft near the rigid rod.

[0009] Furthermore, the filter element includes a filter bag, which is fitted onto the outer surface of the recovery chamber. A pipe joint is provided above the filter bag, which is connected to the feed pipe at the outlet end of the crusher body. A collar is fixedly connected to the side of the filter bag near the shaft, and the collar is fitted onto the outer circumference of the shaft sleeve.

[0010] Furthermore, the inner wall of the collar is provided with a strong spring connected to the outer circumferential surface of the bushing, and the end of the collar away from the frame is provided with a filter cloth that is tightly fitted to the outer circumferential surface of the bushing.

[0011] Furthermore, an outer ring is fixedly connected to the end of the collar away from the filter cloth, and a crescent-shaped arc plate is fixedly connected to the inner wall of the outer ring. The shaft is rotatably mounted with ball bearings that fit against the outer ring and the inner wall of the crescent-shaped arc plate via a support rod set on its outer circumference.

[0012] Furthermore, the bottom of the inner wall of the filter bag is designed with an opening, and the opening at the bottom of the filter bag is sealed and attracted by a magnetic block.

[0013] The technical solution provided by this invention has the following advantages compared with the prior art: This invention includes a recycling section. Waste ABS plastic shells are placed into the feed inlet of the crusher body, where a crushing device further crushes them. The crushed plastic particles and dust then enter the pipe joint of the recycling section. Since the recycling section includes a recycling bin and a filter element, and the recycling bin has a hemispherical design with its opening facing upwards, falling plastic particles directly enter the bin. Simultaneously, filter bags on the filter element are fitted onto the outer circumference of the recycling bin, directly filtering out floating plastic dust. The discharged air will not harm the human body, and it also prevents the continuous or frequent occurrence of plastic dust, thus avoiding the formation of a combustible dust-air mixture.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] The present invention will be further described below with reference to embodiments.

[0019] Example: Please refer to Figures 1-7The present invention provides a technical solution: a crushing device for recycling the shell of a concentrator, comprising: The pulverizer body 1 has a feed inlet 11 on its side and a working chamber 12 at its bottom. The recycling section 2 is located in the space enclosed by the working chamber 12. The recycling section 2 includes a frame 21. The bottom of the frame 21 is fixedly installed below the crusher body 1. A recycling bin 22 is rotatably connected inside the frame 21. The outer surface of the recycling bin 22 is fitted with a filter element 23, and the top of the filter element 23 is connected to the outlet of the crusher body 1 through a feed pipe.

[0020] The recycling bin 22 adopts a hemispherical design and the opening of the recycling bin 22 faces upward. The recycling bin 22 is magnetically connected to the closing plate 222 through the discharge port 221 opened below it. The closing plate 222 and the recycling bin 22 can be connected by a threaded assembly.

[0021] The recycling bin 22 is rotatably connected to a shaft 224 via a bushing 223 on its upper surface. There are two shafts 224, which are symmetrically distributed on the upper surface of the recycling bin 22. A rigid rod 225 is fixedly connected between the adjacent surfaces of a pair of shafts 224. The end of the shaft 224 away from the rigid rod 225 is rotatably connected to the inside of the frame 21.

[0022] A drive housing 211 is fixedly connected to the outer surface of the frame 21 via a mounting bracket. The drive housing 211 is connected to the shaft 224 via a transmission connection. A scraper 226 that fits against the inner wall of the recycling bin 22 is fixedly connected to the side of the shaft 224 near the rigid rod 225.

[0023] The filter element 23 includes a filter bag 231, which is fitted on the outer surface of the recovery chamber 22. A pipe joint 232 connected to the feed guide pipe at the outlet end of the crusher body 1 is provided above the filter bag 231. A collar 233 is fixedly connected to the side of the filter bag 231 near the shaft 224, and the collar 233 is fitted on the outer circumferential surface of the bushing 223.

[0024] The inner wall of the collar 233 is provided with a strong spring 234 that is connected to the outer circumference of the bushing 223. The end of the collar 233 away from the frame 21 is provided with a filter cloth 235 that is tightly attached to the outer circumference of the bushing 223, which plays a protective role and prevents dust from drifting out.

[0025] The end of the collar 233 away from the filter cloth 235 is fixedly connected to an outer ring 236, and the inner wall of the outer ring 236 is fixedly connected to a crescent-shaped arc plate 237. The shaft 224 is rotatably mounted with ball bearings 2242 that fit against the inner wall of the outer ring 236 and the crescent-shaped arc plate 237 via a support rod 2241 set on its outer circumference.

[0026] The bottom of the inner wall of the filter bag 231 is designed with an opening, and the opening at the bottom of the filter bag 231 is sealed with a magnetic block.

[0027] refer to Figure 1-7 Plastic dust is generated during the ABS plastic crushing process. If inhaled, especially if it enters the alveoli through the respiratory tract, long-term accumulation may lead to silicosis. In addition, if plastic dust occurs continuously or frequently and the amount is sufficient to form a mixture of combustible dust and air, it may cause an explosion, posing a threat to the safety of personnel and equipment. To solve the above technical problems, it is necessary to provide a crushing device for concentrator shell recycling. To overcome the aforementioned defects, this invention designs a pulverizing device for recycling the concentrator shell.

[0028] Processing and filtration of plastic casings: In practical applications, the waste plastic shell of the concentrator is placed into the feed inlet 11 of the crusher body 1, and then the crushing device in the crusher body 1 crushes it. The crushed plastic particles and plastic dust enter the pipe joint 232 of the recycling section 2. Since the recycling section 2 includes a recycling bin 22 and a filter element 23, and the recycling bin 22 adopts a hemispherical design with its opening facing upward, the falling plastic particles fall directly into the recycling bin 22. At the same time, the filter bag 231 on the filter element 23 is fitted on the outer circumference of the recycling bin 22, and the floating plastic dust is directly filtered by the filter bag 231. The exhaust air will not cause harm to the human body, and at the same time, it avoids the continuous or frequent occurrence of plastic dust, which could form a mixture of combustible dust and air.

[0029] Recycling of processed plastic casings: In practical applications, after all waste plastic shells have been crushed, the collection box is placed directly below the filter bag 231. Because the bottom of the inner wall of the filter bag 231 has an open design, and the opening at the bottom of the filter bag 231 is sealed with a magnetic block, the magnetic block at the bottom of the filter bag 231 can be manually opened directly (and secured with a clamp). The filtered dust and plastic in the filter bag 231 fall directly into the collection box (the filter bag 231 has an "apple-shaped design" to facilitate dust discharge). Then, the closing plate 222 is manually pulled down (if there are only a small amount of plastic particles, the closing plate 222 and the discharge port 221 can be directly connected magnetically; if there are too many plastic particles, the closing plate 222 and the recycling bin 22 can be connected via a threaded connection), opening the channel of the discharge port 221. The plastic particles in the recycling bin 22 fall directly into the collection box (the channel opened below the filter bag 231 is much larger than the channel of the discharge port 221), completing the recycling of plastic particles and dust.

[0030] It should also be emphasized that some waste plastics require pre-processing, such as washing and preliminary crushing, before further pulverization. As a result, plastic particles may remain on the recycling bin 22, and the filter pores on the filter bag 231 may become clogged with long-term use. To address this, this application includes a scraper 226 and a filter element 23. Specifically, starting the drive housing 211 causes the shaft 224 to rotate around the inside of the frame 21. Simultaneously, the recovery bin 22 is suspended from the shaft 224 via a bushing 223. The shaft 224 supports the recovery bin 22, which, under its own weight, remains in a free-hanging, stationary state. At the same time, the outer circumference of the bushing 223 is connected to a collar 233 via six sets of strong springs 234, which support the collar 233. The collar 233 floats on the outer circumference of the bushing 223, and consequently, the filter bag 231 floats on the outer circumference of the recovery bin 22. As the shaft 224 reciprocates, it drives the scraper 226 to reciprocate along the inner wall of the recovery bin 22, scraping away any remaining plastic particles. The remaining plastic particles are then discharged through the outlet 221. During the reciprocating rotation of the shaft 224, the support rod 2241 and the ball bearing 2242 are driven to reciprocate synchronously. The ball bearing 2242 rolls against the inner wall of the outer ring 236 and the crescent-shaped plate 237, pushing the collar 233 at multiple angles and directions. Combined with the elasticity of the powerful spring 234, the collar 233 and the filter bag 231 vibrate irregularly, accelerating the rapid removal of residual dust from the filter pores.

[0031] The recycling section 2 used in this application has the following advantages: Advantage 1: The recycling bin 22 adopts a hemispherical design and the opening of the recycling bin 22 faces upward. The falling plastic particles fall directly into the recycling bin 22. The filter bag 231 on the filter element 23 is fitted on the outer circumference of the recycling bin 22. The floating plastic dust is directly filtered by the filter bag 231, avoiding the floating of plastic dust.

[0032] Secondly, the opening at the bottom of the filter bag 231 is sealed with a magnetic block. When opened, the filtered dust and plastic in the filter bag 231 fall directly into the collection box. The closing plate 222 and the discharge port 221 can be directly connected by magnetic force to avoid the uniform collection of plastic particles.

[0033] Thirdly, during the reciprocating rotation of the shaft 224, the support rod 2241 and the ball bearing 2242 are driven to reciprocate synchronously. The ball bearing 2242 rolls against the inner wall of the outer ring 236 and the crescent-shaped plate 237, pushing the collar 233 at multiple angles and directions. Combined with the elasticity of the powerful spring 234, the collar 233 and the filter bag 231 vibrate irregularly, accelerating the rapid removal of residual dust from the filter holes and preventing the filter holes from being blocked.

[0034] Fourthly, the filter bag 231 can not only be cleaned using irregular vibration, but also by gently tapping its outer surface manually to quickly remove dust. Secondly, during the reciprocating rotation of the scraper 226, the rotation range of the scraper 226 can be adjusted to allow it to touch the upper part of the filter bag 231, causing the filter bag 231 to deform and vibrate over a wide range, accelerating the shaking of the filter bag 231 and improving the cleaning effect.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
