Description

Technical Field

[0001] The utility model relates to the technical field of construction waste, in particular to a construction waste recycling and processing device. Background Art

[0002] Construction waste refers to the slag, abandoned soil, abandoned materials, silt and other waste generated during the construction, laying, demolition and repair of various buildings, structures, pipelines, etc. by construction units or individuals. In order to reduce waste, people usually screen out reusable construction waste for recycling.

[0003] The current waste recycling and processing device is not convenient for handling the moisture on some wet waste materials during use, which increases the difficulty of crushing some wet and soft waste materials. In addition, the moisture can also cause rust on the crushing device, affecting the service life of the crushing device.

[0004] In the prior art, a Chinese patent with publication number CN216025188U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a construction waste recycling and processing device, belonging to the technical field of building construction equipment, comprises a box body, a feed port is arranged on the top of the box body, a feed barrel is arranged below the feed port, a shield plate passes through the feed barrel, a heating plate is arranged inside the shield plate, an electric push rod is arranged on one side of the box body, a heat insulation block is arranged on one side of the electric push rod, the heat insulation block and the shield plate are fixedly connected, and the shield plate can be used to The feed barrel is closed to prevent the waste from falling down, and then the air inside the feed barrel is heated by the heating plate to dry the moist waste by the heat. After drying, the baffle is moved by the electric push rod to open the feed barrel to allow the waste to continue to fall down, so as to prevent the moisture on some moist waste from not only increasing the difficulty of crushing the waste, but also causing the rust of the crushing roller and affecting the service life of the crushing roller, thereby realizing the automation of the processing device. However, when the waste is crushed, the waste is easily stuck on the surface of the crushing roller, thereby affecting the efficiency of the recycling and processing of construction waste. Utility Model Content

[0005] The purpose of the utility model is to provide a construction waste recycling and processing device to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A construction waste recycling and processing device comprises a base and a controller; a recycling box is fixedly installed on the top of the base, a support frame is fixedly connected to the top of the base outside the recycling box, a processing box is fixedly installed on the top of the support frame, the processing box is located on the top of the recycling box, a connecting frame is fixedly installed on the top of the recycling box, the connecting frame is fixedly connected to the bottom of the processing box, a motor is fixedly installed on one end of the processing box, a controller is fixedly connected to one end of the processing box, the controller is located on one side of the motor, a feeding frame is fixedly installed on the top of the processing box, a crushing roller is rotatably installed inside the processing box, one end of the crushing roller on the other side of the processing box is fixedly connected to the motor, and a cleaning wire is fixedly installed inside the processing box, the cleaning wire is located on both sides of the crushing roller.

[0008] The above technical scheme is adopted. In this scheme, the processing box and the base can be connected by installing a support frame, thereby improving the stability of the processing box. When the motor drives its output shaft to rotate, it can drive the crushing roller on the other side of the processing box to rotate synchronously. At the same time, the two crushing rollers inside the processing box are meshed with each other. When the crushing roller on the other side of the processing box rotates, it can synchronously drive the crushing roller on one side of the processing box to rotate in the opposite direction, thereby realizing the crushing of construction waste for subsequent recycling work. In the process of the two crushing rollers rotating, the cleaning wire can scrape off the waste debris adhered to the surface of the crushing roller. At the same time, the cleaning wire can rebound, thereby being able to move the waste debris, ensuring that the waste debris cleaned from the surface of the crushing roller can slide down, thereby realizing the cleaning of the surface of the crushing roller, and reducing the possibility of the crushing roller being stuck.

[0009] A further improvement of the technical solution of the utility model is that the crushing roller includes crushing convex strips, which are evenly distributed on the periphery of the crushing roller and are slidably connected to the crushing roller. A cavity is opened inside the crushing roller, and a plurality of limit frames are fixedly installed inside the cavity, and each limit frame is mutually engaged with each crushing convex strip.

[0010] The above technical solution is adopted. In this solution, the crushing convex strip is slidably arranged inside the crushing roller so that the crushing convex strip can slide outside the crushing roller. When the crushing convex strip slides toward the inside of the crushing roller, it is convenient for the waste to slide down from the periphery of the crushing roller, thereby avoiding the crushing roller from getting stuck. In the process of crushing the construction waste by using the crushing roller, the infrared sensor and the receiver can be turned on, and the connecting pipe can be connected to the external air supply (exhaust) equipment. At this time, the external air supply (exhaust) equipment supplies external gas into the cavity, thereby automatically pushing the crushing convex strip to the outermost side, thereby facilitating the subsequent crushing of the construction waste by using the crushing roller. When the receiver is at the specified time When the infrared ray emitted by the infrared sensor cannot be received within a specified time, it means that the construction waste is being crushed and discharged normally, that is, the crushing roller is not stuck. When the receiver can receive the infrared ray emitted by the infrared sensor within a specified time, it means that the construction waste may not be able to be crushed and discharged (that is, the crushing roller has begun to get stuck). At this time, the result is transmitted to the controller, and the external air supply (exhaust) equipment performs air extraction to form a vacuum state in the cavity, so that the crushing convex strips can be automatically adsorbed into the interior of the cavity, so that the waste stuck on the surface of the crushing roller can slide to the bottom along the surface of the crushing roller, thereby solving the problem of material jamming and improving the effect of construction waste recycling.

[0011] A further improvement of the technical solution of the utility model is that an infrared sensor is fixedly installed on one side of the connecting frame, a receiver is fixedly connected to the other side of the connecting frame, the receiver and the infrared sensor correspond to each other, a connecting pipe is fixedly installed on the other end of the processing box, and the connecting pipe is fixedly connected to the other end of the crushing roller.

[0012] The above technical solution is adopted. In this solution, by installing an infrared sensor and a receiver, it is possible to detect whether the crushing roller is stuck. At the same time, by installing a connecting pipe, the crushing roller can be connected to an external air supply (exhaust) device, so as to facilitate timely treatment of the surface of the crushing roller and avoid the crushing roller being stuck for a long time and affecting the efficiency of the construction waste recycling work.

[0013] A further improvement of the technical solution of the utility model is that: the end of each crushing convex strip is provided with an inclined groove inclined toward the outside.

[0014] The above technical solution is adopted. In this solution, by providing an outwardly inclined groove at the end of the crushing convex strip, it is possible to facilitate the construction waste to slide down along the inclined groove to a certain extent, further reducing the possibility of the crushing roller getting stuck.

[0015] A further improvement of the technical solution of the utility model is that a protective plate is fixedly installed inside the processing box on the top of the crushing roller, the top of the protective plate is an inclined surface inclined inwardly, and the width of the inner side of the protective plate is wider than the top of the crushing roller.

[0016] By adopting the above technical solution, in this solution, the construction waste can be guided between the two crushing rollers by installing the protective plate, thereby ensuring that all the construction waste can be crushed, thereby improving the crushing effect.

[0017] A further improvement of the technical solution of the utility model is that a magnet is fixedly installed inside the protective plate, and through grooves are opened on both sides of the processing box, and the through grooves are located on the top of the protective plate.

[0018] The above technical solution is adopted. In this solution, by installing magnets, the steel waste in the construction waste can be adsorbed when the construction waste enters the processing box through the feed frame. By providing a through groove, it is convenient for the user to take out the steel waste adsorbed by the magnet for processing, thereby avoiding the steel waste from being easily stuck on the surface of the crushing roller when the steel waste is subsequently crushed, and further reducing the possibility of the crushing roller being stuck.

[0019] A further improvement of the technical solution of the utility model is that a sieve plate is fixedly installed inside the recycling box, the sieve plate runs through one side of the recycling box, and the sieve plate is in a state of being inclined toward the bottom of one side.

[0020] The above technical solution is adopted. In this solution, the crushed construction waste can be screened by installing a sieve plate. A plurality of through holes are opened on the surface of the sieve plate. When the crushed construction waste falls onto the surface of the sieve plate, the construction waste with a volume larger than the through holes is intercepted at the top of the sieve plate and slides to one side for unloading. The construction waste with a volume smaller than the through holes can pass through the through holes and continue to slide downward.

[0021] A further improvement of the technical solution of the utility model is that a material guide plate is fixedly installed inside the recovery box at the bottom of the screen plate, the material guide plate runs through the other side of the recovery box, and the material guide plate is inclined toward the bottom of the other side.

[0022] By adopting the above technical solution, in this solution, by installing the guide plate, the construction waste with a volume smaller than the through hole can be guided to the other side, and the construction waste with a volume smaller than the through hole can be discharged.

[0023] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0024] 1. The utility model provides a construction waste recycling and processing device. In the process of crushing construction waste, the cleaning wire can scrape off the waste debris adhered to the surface of the crushing roller, so that the waste debris can slide downward, reducing the possibility of the crushing roller getting stuck.

[0025] 2. The utility model provides a construction waste recycling and processing device, which makes it possible for the crushing convex strips to slide inside the crushing roller. When the crushing convex strips slide toward the inside of the crushing roller, the waste can slide down from the periphery of the crushing roller, thereby avoiding the crushing roller from getting stuck.

[0026] 3. The utility model provides a construction waste recycling and processing device. Through the cooperation between the infrared sensor and the receiver, it can detect whether the crushing roller is stuck. When the receiver can receive the infrared rays emitted by the infrared sensor within the specified time, the cavity is evacuated by using an external air supply (exhaust) device, so that the crushing convex strip moves toward the inside of the cavity, so that the waste stuck on the surface of the crushing roller can slide down to the bottom along the surface of the crushing roller, thereby solving the problem of material jamming and further improving the effect of construction waste recycling and processing.

[0027] 4. The utility model provides a construction waste recycling and processing device, which can guide the construction waste to between two crushing rollers by using a protective plate, thereby ensuring that all construction waste can be crushed, and can use a magnet to adsorb steel waste in the construction waste. The user can then take out the steel waste adsorbed by the magnet through the through groove, thereby avoiding the subsequent steel waste being stuck on the surface of the crushing roller and affecting the recovery of the construction waste, and further reducing the possibility of the crushing roller being stuck.

DETAILED DESCRIPTION

[0037] The present invention is further described in detail below in conjunction with the embodiments:

[0038] Example 1

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a construction waste recycling and processing device, including a base 1 and a controller 4; a recycling box 3 is fixedly installed on the top of the base 1, and a support frame 201 is fixedly connected to the top of the base 1 outside the recycling box 3, and a processing box 2 is fixedly installed on the top of the support frame 201, and the processing box 2 is located on the top of the recycling box 3, and a connecting frame 9 is fixedly installed on the top of the recycling box 3, and the connecting frame 9 is fixedly connected to the bottom of the processing box 2, a motor 5 is fixedly installed at one end of the processing box 2, and a controller 4 is fixedly connected to one end of the processing box 2, and the controller 4 is located on one side of the motor 5, and a feeding frame 202 is fixedly installed on the top of the processing box 2, and a crushing roller 6 is rotatably installed inside the processing box 2, and one end of the crushing roller 6 on the other side of the processing box 2 is fixedly connected to the motor 5, and a cleaning wire 8 is fixedly installed inside the processing box 2, and the cleaning wire 8 is located on both sides of the crushing roller 6.

[0040] In this embodiment, the processing box 2 and the base 1 can be connected by installing the support frame 201, thereby improving the stability of the processing box 2. When the motor 5 drives its output shaft to rotate, the crushing roller 6 on the other side of the processing box 2 can be driven to rotate synchronously. At the same time, the two crushing rollers 6 inside the processing box 2 are meshed with each other. When the crushing roller 6 on the other side of the processing box 2 rotates, the crushing roller 6 on one side of the processing box 2 can be driven to rotate in the opposite direction, thereby realizing the crushing of construction waste for subsequent recycling work. During the rotation of the two crushing rollers 6, the cleaning wire 8 can scrape off the waste debris adhered to the surface of the crushing roller 6. At the same time, the cleaning wire 8 can rebound, thereby being able to move the waste debris, ensuring that the waste debris cleaned from the surface of the crushing roller 6 can slide down, thereby realizing the cleaning of the surface of the crushing roller 6 and reducing the possibility of the crushing roller 6 getting stuck.

[0041] Example 2

[0042] like Figure 2 , Figure 4 and Figure 6 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the crushing roller 6 includes a crushing ridge 601, which is evenly distributed on the periphery of the crushing roller 6, and the crushing ridge 601 is slidably connected to the crushing roller 6, a cavity 603 is opened inside the crushing roller 6, and a plurality of limit frames 602 are fixedly installed inside the cavity 603, and each limit frame 602 is mutually engaged with each crushing ridge 601, an infrared sensor 11 is fixedly installed on one side of the connecting frame 9, and a receiver 12 is fixedly connected on the other side of the connecting frame 9, and the receiver 12 corresponds to the infrared sensor 11, and a connecting pipe 10 is fixedly installed on the other end of the processing box 2, and the connecting pipe 10 is fixedly connected to the other end of the crushing roller 6, and the end of each crushing ridge 601 is opened with an inclined groove inclined to the outside.

[0043] In this embodiment, the crushing convex strip 601 is slidably arranged inside the crushing roller 6 so that the crushing convex strip 601 can slide outside the crushing roller 6. When the crushing convex strip 601 slides toward the inside of the crushing roller 6, it is convenient for the waste to slide down from the outer periphery of the crushing roller 6, thereby avoiding the crushing roller 6 from getting stuck. In the process of crushing the construction waste by using the crushing roller 6, the infrared sensor 11 and the receiver 12 can be turned on, and the connecting pipe 10 can be connected to the external air supply (exhaust) equipment. At this time, the external air supply (exhaust) equipment supplies external gas into the cavity 603, thereby automatically pushing the crushing convex strip 601 to the outermost side, thereby facilitating the subsequent crushing of the construction waste by using the crushing roller 6. When the receiver 12 fails to receive the infrared rays emitted by the infrared sensor 11 within the specified time, it indicates that the construction waste is in normal condition. When crushing and unloading are carried out, that is, the crushing roller 6 is not stuck, when the receiver 12 can receive the infrared rays emitted by the infrared sensor 11 within the specified time, it means that the construction waste may not be crushed and unloaded (that is, the crushing roller 6 has begun to get stuck). At this time, the result is transmitted to the controller 4, and the external air supply (exhaust) equipment performs air extraction to form a vacuum state in the cavity 603, so that the crushing convex strip 601 can be automatically adsorbed into the interior of the cavity 603, so that the waste stuck on the surface of the crushing roller 6 can slide down along the surface of the crushing roller 6 to the bottom, thereby solving the problem of material jamming and improving the effect of recycling and processing of construction waste. By providing an inclined groove inclined outward at the end of the crushing convex strip 601, it can facilitate the construction waste to slide down along the inclined groove to a certain extent, further reducing the possibility of the crushing roller 6 getting stuck.

[0044] Example 3

[0045] like Figure 1 , Figure 2 and Figure 3 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a protective plate 7 is fixedly installed inside the processing box 2 on the top of the crushing roller 6, the top of the protective plate 7 is an inclined surface inclined inward, and the width of the inner side of the protective plate 7 is wider than the top of the crushing roller 6, a magnet 701 is fixedly installed inside the protective plate 7, and through grooves 203 are opened on both sides of the processing box 2, and the through grooves 203 are located at the top of the protective plate 7.

[0046] In this embodiment, by installing the protective plate 7, the construction waste can be guided between the two crushing rollers 6, thereby ensuring that all the construction waste can be crushed and improving the crushing effect. By installing the magnet 701, the steel waste in the construction waste can be adsorbed when the construction waste passes through the feed frame 202 and enters the processing box 2. By providing the through groove 203, the user can easily take the steel waste adsorbed by the magnet 701 for processing, thereby avoiding the steel waste from being easily stuck on the surface of the crushing roller 6 when the steel waste is subsequently crushed, and further reducing the possibility of the crushing roller 6 being stuck.

[0047] Example 4

[0048] like Figure 1 and Figure 5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, a sieve plate 301 is fixedly installed inside the recycling box 3, the sieve plate 301 passes through one side of the recycling box 3, and the sieve plate 301 is inclined toward the bottom of one side, and a material guide plate 302 is fixedly installed inside the recycling box 3 at the bottom of the sieve plate 301, the material guide plate 302 passes through the other side of the recycling box 3, and the material guide plate 302 is inclined toward the bottom of the other side.

[0049] In this embodiment, the crushed construction waste can be screened by installing the sieve plate 301. A plurality of through holes are provided on the surface of the sieve plate 301. When the crushed construction waste falls onto the surface of the sieve plate 301, the construction waste with a volume larger than the through holes is intercepted at the top of the sieve plate 301 and slides to one side for unloading. The construction waste with a volume smaller than the through holes can continue to slide downward through the through holes. By installing the guide plate 302, the construction waste with a volume smaller than the through holes can be guided to the other side for unloading.

[0050] The working principle of the construction waste recycling and processing device is described in detail below.

[0051] like Figure 1-Figure 7As shown, the user first turns on the infrared sensor 11 and the receiver 12, and connects the connecting pipe 10 to the external gas supply (exhaust) device, and uses the external gas supply (exhaust) device to supply external gas into the cavity 603, so that the crushing convex strip 601 is pushed to the outermost side and fixed, and then the motor 5 drives the crushing roller 6 to rotate, and the construction waste is poured into the interior of the processing box 2 through the feeding frame 202. When the construction waste is poured into the interior of the processing box 2, the protective plate 7 can be used to guide the construction waste to between the two crushing rollers 6, so that The invention ensures that all construction waste can be crushed. The magnet 701 can be used to absorb the steel waste in the construction waste. The user can then take out the steel waste absorbed by the magnet 701 through the through groove 203, thereby avoiding the subsequent steel waste being stuck on the surface of the crushing roller 6 and affecting the efficiency of crushing other construction waste. In the process of crushing the construction waste by the crushing roller 6, the cleaning wire 8 can be used to scrape off the waste adhered to the surface of the crushing roller 6, thereby reducing the possibility of the crushing roller 6 being stuck. At the same time, the infrared sensor 11 continuously sends infrared rays to the receiver 12. When the receiver 12 receives the infrared rays emitted by the infrared sensor 11 within the specified time, it indicates that the crushing roller 6 has begun to be stuck. The user controls the external air supply (exhaust) equipment to exhaust the cavity 603, and automatically absorbs the crushing convex strip 601 to the inside of the cavity 603, thereby facilitating the waste stuck on the surface of the crushing roller 6 to slide to the bottom along the surface of the crushing roller 6, thereby solving the problem of material sticking and improving the effect of recycling and treating construction waste. The materials can enter the interior of the recycling box 3 through the connecting frame 9. When the crushed construction waste falls onto the surface of the sieve plate 301, the construction waste with a volume larger than the through-holes of the sieve plate 301 is intercepted at the top of the sieve plate 301 and slides to one side. The construction waste with a volume smaller than the through-holes can continue to slide downward through the through-holes and then slide to the top of the guide plate 302. By installing the guide plate 302, the construction waste with a volume smaller than the through-holes of the sieve plate 301 can be guided to the other side, thereby realizing automatic material discharge processing of the construction waste with a volume smaller than the through-holes.

[0052] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
