Description

Technical Field

[0001] This invention relates to the field of waste recycling and treatment technology, and in particular to a device for recycling and treating cable waste particles. Background Technology

[0002] With the continuous increase in cable usage, the amount of cable waste generated is also growing rapidly. Polyvinyl chloride (PVC) cable material particles are an important component of cables; effective recycling of these particles not only enables resource reuse and reduces production costs but also minimizes environmental pollution.

[0003] However, existing cable waste particle recycling and processing devices have many problems in practical applications:

[0004] On the one hand, cable waste particles usually contain a certain amount of moisture. If they are not effectively dried before processing, they will stick together and block during the crushing process. For example, traditional drying methods may not be able to heat the cable waste particles continuously and evenly, resulting in poor drying effect and difficulty in effectively reducing the moisture content, which in turn seriously affects the crushing quality and the stability of subsequent processing procedures.

[0005] On the other hand, during the crushing process, there is a lack of targeted drying measures for the cable waste particles being crushed. Existing drying methods often cannot directly act on the key crushing areas, and cannot dry the cable waste particles being crushed in a timely and effective manner, resulting in low drying efficiency. It is also difficult to ensure that the cable waste particles are always dry during the crushing process, which makes the crushing work difficult to carry out smoothly and significantly increases the processing time and cost. Summary of the Invention

[0006] This invention relates to a device for recycling and processing cable waste particles, which solves the problems of traditional drying methods that are difficult to effectively reduce the moisture content of cable waste particles before processing, affecting the crushing quality and subsequent processes, and the lack of targeted drying measures during crushing, resulting in low drying efficiency and difficulty in drying particles.

[0007] This invention provides a device for recycling and processing cable waste particles, specifically comprising: a conveying cylinder; a feeding pipe connected to its conveying cavity is installed on the top left side of the outer circumference of the conveying cylinder, and a feeding pipe connected to its conveying cavity is installed on the bottom right side of the outer circumference of the conveying cylinder; an external heating layer is installed on the outer circumference of the conveying cylinder relative to the area between the feeding pipe and the feeding pipe; a crushing shell is fixedly installed on the bottom end face of the feeding pipe, and the crushing cavity of the crushing shell is connected to the conveying cavity of the conveying cylinder through the feeding pipe; an auxiliary block is provided on the left end face of the crushing shell, and an auxiliary input opening connected to the crushing cavity of the crushing shell is opened on the left end face of the auxiliary block; a heating pipe is installed inside the auxiliary input opening, and a set of fans is fixedly installed at the adjacent left opening end inside the auxiliary input opening, with the air supply end of the fan set facing to the right.

[0008] Furthermore, a conveying auger is rotatably installed inside the conveying cavity of the conveying cylinder, and a set of conveying drive motors is fixedly installed on the right end face of the conveying cylinder. The shaft end of the conveying drive motor passes through the conveying cavity of the conveying cylinder and is fixedly connected to the conveying auger.

[0009] Furthermore, two sets of crushing blades are symmetrically mounted inside the crushing chamber of the crushing shell; a set of crushing drive motors is fixedly mounted on the right end face of the crushing shell relative to the axis of the two sets of crushing blades, and the shaft ends of the two sets of crushing drive motors pass through the crushing chamber of the crushing shell and are fixedly connected to the two sets of crushing blades respectively.

[0010] Furthermore, an intercepting mesh plate is fixedly installed inside the auxiliary input opening adjacent to the right opening end, and the intercepting mesh plate completely covers the right opening end of the auxiliary input opening.

[0011] Furthermore, the auxiliary input opening is directly opposite the crushing area between the two sets of crushing tools.

[0012] Furthermore, a screen plate is fixedly installed inside the crushing chamber of the crushing shell, and the screen plate is located on the lower side of the two sets of crushing blades; an extension plate that penetrates the left end face of the crushing shell is fixedly installed on the left end face of the screen plate, and a vibration motor is fixedly installed on the bottom end face of the extension plate.

[0013] Furthermore, a converging discharge pipe with a round top and square bottom structure is fixedly installed on the bottom end face of the crushing shell, and the converging discharge pipe is connected to the crushing chamber of the crushing shell; a supporting frame is fixedly installed on the outer end face of the crushing shell, and a top plate is fixedly installed on the left half of the top surface of the supporting frame, and the top surface of the top plate is fixedly connected to the conveying cylinder and the outer peripheral surface of the external heating layer through a support plate.

[0014] This invention provides a device for recycling and processing cable waste particles, which has the following beneficial effects:

[0015] This invention utilizes an external heating layer to continuously and uniformly heat the conveying cylinder, enabling effective preliminary drying of cable waste particles during transport. This rapidly evaporates moisture from the particles, significantly reducing their water content. Furthermore, once the particles reach the crushing shell, the heating pipes and fan unit work together to evenly blow hot air into the shell, further drying the particles. This design effectively reduces the water content of the cable waste particles before crushing, preventing problems such as adhesion and blockage caused by excessive moisture. This greatly ensures crushing quality, lays a solid foundation for subsequent processing steps, and enhances the stability and reliability of the entire process.

[0016] The auxiliary input opening of this invention faces the crushing area between the two sets of crushing blades, allowing hot air to directly act on this critical area and effectively dry the cable waste particles being crushed. This targeted drying method not only improves the drying effect but also significantly enhances the drying efficiency, ensuring that the cable waste particles remain dry throughout the crushing process. This effectively guarantees the smooth progress and high-quality completion of the crushing work, saving processing time and costs.

[0017] The intercepting mesh plate installed inside the auxiliary input opening of this invention can effectively prevent large waste particles or debris from entering the crushing shell, while ensuring the normal flow of hot air. This design not only avoids damage to the crushing equipment by debris, but also ensures the smooth progress of the drying process, improving the safety and stability of equipment operation.

[0018] This invention uses a vibrating motor to drive a screen plate to vibrate at high frequency, which enables fine screening of crushed cable waste particles. Smaller particles that meet the size requirements pass through the screen plate and are discharged, while larger particles are further crushed by the crushing blades during the rebound process until they can pass through the screen plate. This design achieves effective crushing and fine screening of cable waste particles, improves product quality, and enhances the precision of cable waste processing. Attached Figure Description

[0032] Example: Please refer to Figures 1 to 7 :

[0033] This invention proposes a device for recycling and processing cable waste particles, comprising: a conveying cylinder 1, a feeding pipe 102 connected to its conveying cavity installed on the top left side of the outer circumference of the conveying cylinder 1, and a feeding pipe 103 connected to its conveying cavity installed on the bottom right side of the outer circumference of the conveying cylinder 1; an external heating layer 101 installed on the outer circumference of the conveying cylinder 1 relative to the area between the feeding pipe 102 and the feeding pipe 103; a crushing shell 2 fixedly installed on the bottom end face of the feeding pipe 103, the crushing cavity of the crushing shell 2 being connected to the conveying cavity of the conveying cylinder 1 through the feeding pipe 103; an auxiliary block 202 provided on the left end face of the crushing shell 2, the auxiliary block 202 having an auxiliary input opening 2010 connected to the crushing cavity of the crushing shell 2 on its left end face; and a heating element installed inside the auxiliary input opening 2010. A heat pipe 2011 and an auxiliary input opening 2010 are respectively equipped with a fan assembly 206 fixedly installed at the left side opening end, with the air supply end of the fan assembly 206 facing to the right; a conveying auger 105 is rotatably installed inside the conveying chamber of the conveying cylinder 1, and a set of conveying drive motors 104 are fixedly installed on the right end face of the conveying cylinder 1, with the shaft end of the conveying drive motor 104 passing through the conveying chamber of the conveying cylinder 1 and fixedly connected to the conveying auger 105; two sets of crushing blades 207 are rotatably installed in a symmetrical manner inside the crushing chamber of the crushing shell 2; a set of crushing drive motors 203 are fixedly installed on the right end face of the crushing shell 2 relative to the axis of the two sets of crushing blades 207, with the shaft ends of the two sets of crushing drive motors 203 passing through the crushing chamber of the crushing shell 2 and fixedly connected to the two sets of crushing blades 207 respectively.

[0034] In this embodiment of the invention, an intercepting mesh plate 209 is fixedly installed inside the auxiliary input opening 2010 adjacent to the right opening end, and the intercepting mesh plate 209 completely covers the right opening end of the auxiliary input opening 2010; the auxiliary input opening 2010 is directly opposite the crushing area between the two sets of crushing blades 207; a screen plate 208 is fixedly installed inside the crushing chamber of the crushing shell 2, and the screen plate 208 is located below the two sets of crushing blades 207; an extension plate 204 penetrating the left end face of the screen plate 208 is fixedly installed on the left end face of the crushing shell 2, and a vibration motor 205 is fixedly installed on the bottom end face of the extension plate 204.

[0035] In this embodiment of the invention, a converging discharge pipe 201 with a round top and square bottom structure is fixedly installed on the bottom end face of the crushing shell 2. The converging discharge pipe 201 is connected to the crushing chamber of the crushing shell 2. A supporting frame 3 is fixedly installed on the outer end face of the crushing shell 2. A top plate 301 is fixedly installed on the left half of the top surface of the supporting frame 3. The top surface of the top plate 301 is fixedly connected to the outer peripheral surface of the conveying cylinder 1 and the external heating layer 101 through a support plate 302. The supporting frame 3 of the present invention plays the role of supporting the entire device. The top plate 301 and the support plate 302 fix the conveying cylinder 1 and the external heating layer 101 in a suitable position to ensure the stability of the device.

[0036] The working principle of this embodiment:

[0037] First, cable waste particles are fed into the conveying chamber of the conveying cylinder 1 through the feeding pipe 102. The conveying drive motor 104 starts, driving the conveying auger 105 to rotate, causing the cable waste particles to move from left to right within the conveying cylinder 1. During the conveying process, the external heating layer 101 continuously and evenly transfers heat to the conveying cylinder 1, heating the cable waste particles within the conveying cylinder 1. As heat is continuously transferred, the moisture in the cable waste particles is gradually evaporated, achieving a preliminary drying effect. This operation effectively reduces the moisture content of the cable waste particles, preparing them adequately for subsequent processing steps.

[0038] After preliminary drying, the cable waste particles slowly enter the crushing chamber of the crushing shell 2 through the feeding pipe 103. At the auxiliary input opening 2010 of the crushing shell 2, the heating pipe 2011 is in the starting heating state, which rapidly heats the incoming air. The heated air is then blown evenly into the internal space of the crushing shell 2 by the strong wind of the fan group 206. This heat flow will fully contact the cable waste particles, further drying them. This effectively ensures that the moisture content of the cable waste particles is reduced as much as possible before the crushing process, avoiding problems such as adhesion and blockage during the crushing process due to excessive moisture content. This greatly ensures the crushing quality and lays a good foundation for subsequent processing steps.

[0039] When the cable waste particles enter the crushing chamber, the two sets of crushing drive motors 203 start, driving the two sets of crushing blades 207 to rotate and crush the cable waste particles. Furthermore, the auxiliary input opening 2010 is positioned directly opposite the crushing area between the two sets of crushing blades 207. When the heating tube 2011 heats the air entering the auxiliary input opening 2010, the fan group 206 blows this hot air into the crushing shell 2. The hot air can then directly act on this critical crushing area without any obstruction. In this way, not only can the cable waste particles being crushed be dried in a timely and effective manner, but the drying effect and efficiency are also greatly improved. This ensures that the cable waste particles remain relatively dry during the crushing process, providing a strong guarantee for the smooth progress and high-quality completion of the crushing work.

[0040] The intercepting mesh plate 209, which is fixedly installed inside the auxiliary input opening 2010 adjacent to the right opening end, can prevent large waste particles or debris from entering the crushing shell 2 from the auxiliary input opening 2010, while also ensuring the normal flow of hot air.

[0041] The crushed cable waste particles fall onto the screen plate 208 under the natural force of gravity. At this time, the power generated by the vibrating motor 205 is transmitted to the extension plate 204, which in turn drives the screen plate 208 to vibrate at high frequency. During the continuous and regular vibration of the screen plate 208, smaller particles that meet the size requirements pass smoothly through the mesh of the screen plate 208 and fall into the lower converging discharge pipe 201 and are discharged. Larger particles that cannot pass through the mesh of the screen plate 208 remain on the screen plate 208. Under the strong vibration of the screen plate 208, these larger particles are constantly bounced up. During their bounce, they will come into contact with the crushing blades 207 again. The crushing blades 207 will further crush these larger particles until their size is reduced to be able to pass through the screen plate 208, thereby achieving fine screening and effective crushing of cable waste particles.
