Description

Technical Field

[0001] This invention belongs to the field of CPVC pipe recycling technology, specifically relating to a CPVC pipe recycling device for underground cables. Background Technology

[0002] Underground cables are widely used in power transmission, communication transmission and other fields. They are usually encased in CPVC pipes to provide insulation, corrosion resistance, pressure resistance and protection for the internal cables. With the continuous advancement of urban power grid transformation, old line replacement and infrastructure construction, a large number of old or abandoned underground cables are replaced and removed, resulting in a large amount of CPVC pipe waste.

[0003] However, the existing traditional flushing methods for CPVC pipes are difficult to remove stubborn impurities such as yellow mud, cement lumps, and sand that are often solidified on the outer wall, which affects the quality of subsequent crushing and recycling and poses safety hazards. Therefore, there is a need to provide a recycling device for CPVC pipes used in underground cables to solve the above problems. Summary of the Invention

Three sets of parallel shock-absorbing springs are arrayed between two sets of disc spring connecting seats at the upper end of the mounting base. The other end of the shock-absorbing springs is fixed to the bottom of the conveying top seat.

[0007] The present invention further explains that the conveying roller is composed of multiple cones that are alternately and in opposite directions connected in sequence, with adjacent cones being symmetrically connected, and friction threads are provided on the surface of the odd-numbered cones.

[0008] The present invention further describes that: each even-numbered conveyor roller is provided with a drive assembly at its front end. The drive assembly consists of a driven bevel gear, a double bevel gear, a first motor, a bevel gear transmission wheel, and a transmission belt, which enables the conveyor roller to be driven to rotate. The drive assemblies of adjacent even-numbered conveyor rollers are connected in series via the transmission belt. The double bevel gear consists of two bevel gears fixedly connected coaxially. One bevel gear meshes with the driven bevel gear, and the other bevel gear meshes with the bevel gear transmission wheel. The rotation direction of the bevel gear transmission wheel is parallel to that of the conveying top seat. The bevel gear transmission wheel is an integral structure, having both a bevel gear part and a pulley part.

[0009] The present invention further describes that the cleaning mechanism includes a top rinsing frame, a spray pipe, a spray head, a cleaning brush, a bottom rinsing pipe, a flushing head, and water channels. The top rinsing frame is installed on the side of the mounting base, and the mounting base and the top rinsing frame do not contact each other.

A cleaning brush that is rotatably mounted to the top rinsing frame is installed below the spray head. Water channels are arrayed on the top surface of the mounting base. A bottom rinsing pipe is fixedly installed on the side of the mounting base, and a flushing head is fixedly installed in a flow path on the side of the bottom rinsing pipe. The positions of the flushing head and the water channels correspond to each other.

[0010] The present invention further describes that the spray pipe is installed in a U-shape on the top of the top rinsing frame, and the spray head is installed in a parallel array at the bottom of the top rinsing frame.

[0011] The present invention further describes that: the water channel has a circular trough structure, the water channel is opened at an angle, and the bottom of the end of the water channel near the punch is higher than the side away from the punch.

[0012] The invention further describes the following: The recycling and crushing mechanism includes a recycling pipe, a second motor, a drive gear set, a transmission roller, a third motor, a second gear set, a crushing cutter roller, a crushing channel, a slag suction bucket, a drive external gear, a drive gear, a fourth motor, a fixed cylinder, bearings, a sector-shaped magnetic pole set, an inclined plate, a conveyor belt, a transmission pulley, and a crushing outlet. A recycling pipe is installed on the right side of the conveying top seat, enclosing the right end of the conveying top seat. Two sets of transmission rollers are installed inside the recycling pipe near the port of the conveying top seat. A drive gear set for driving the transmission rollers is installed at the top of the recycling pipe. A second motor is fixedly installed at the top of the drive gear set. A crushing cutter roller is installed inside the recycling pipe, located to the right of the transmission roller. A second gear set is installed at the top of the crushing cutter roller. Driven by a third motor at the top, a slag suction bucket is installed on the right side of the crushing roller. A drive gear is fixedly installed at the front end of the slag suction bucket, and a drive gear is meshed on the side of the drive gear. The drive gear is installed via a fourth motor at the front end. Inside the slag suction bucket, three sets of fan-shaped magnetic poles with concentric centers are installed. The three sets of fan-shaped magnetic poles are fixed to a fixed cylinder inside. The fixed cylinder is fixed to a recovery pipe. The slag suction bucket is rotatably connected to the fixed cylinder through a bearing installed at the center. The bearing is located in the gap between the fan-shaped magnetic poles. An inclined plate fixed to the recovery pipe is installed on the right side of the slag suction bucket. A conveyor belt is installed below the right side of the recovery pipe. The left and right sides of the conveyor belt are driven by transmission pulleys that are tightly installed. A crushed material outlet is installed at the right end of the recovery pipe.

[0013] The present invention further explains that: the drive gear set consists of four sets of meshing gears, the transmission rollers form a rotating structure through the drive gear set, and the two sets of transmission rollers rotate in opposite directions.

[0014] The present invention further explains that: the slag suction bucket forms a rotating structure through the cooperation between the driving external gear and the active gear; the sector magnetic pole group is a sector structure missing on the side near the inclined plate; the inclined plate and the recovery pipe are fixedly and inclinedly installed; and the side of the inclined plate near the slag suction bucket is installed at a higher height.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: the present invention, By setting up a vibration transmission mechanism consisting of a vibration motor, a polarizing wheel, a disc spring connector, and a damping spring, and with the multi-stage damping design of the shock absorber and disc spring connector, the conveying top seat generates high-frequency, low-amplitude stable vibration, causing the CPVC pipe to continuously bounce and tumble during the transmission process, effectively shaking off surface-solidified dirt, cement lumps, and other impurities; at the same time, it avoids vibration from causing impact damage to the mounting base, ensuring the long-term stability and reliability of the equipment. By designing the conveyor rollers as multiple cones alternately and oppositely connected, with friction threads on the surface of the odd-numbered cones, and setting a series drive assembly consisting of a driven bevel gear, a double bevel gear, a bevel gear transmission wheel, and a transmission belt at the front end of the even-numbered conveyor rollers, the pipe can continuously rotate while moving to the right, thus exposing the outer wall of the pipe to the cleaning area in all directions and improving the cleaning coverage. By setting up a top cleaning assembly consisting of a top flushing frame, spray pipes, spray heads, and cleaning brushes, and a bottom flushing structure consisting of a bottom flushing pipe, a flushing head, and a water channel, the upper and lower sides of the pipe outer wall can be flushed simultaneously. At the same time, the water channel adopts an inclined circular trough structure with the bottom of the end near the flushing head being higher than the end away, so that sewage and impurities can be discharged smoothly by gravity, avoiding water accumulation and blockage, and further improving the cleaning effect and equipment cleanliness. By setting up a recycling and crushing mechanism, the crushed material comes into contact with the slag suction bucket during the conveying process. The magnetic force generated by the fan-shaped magnetic pole group adsorbs ferromagnetic impurities, and the impurities are released above the inclined plate by the missing structure of the fan-shaped magnetic pole group. This achieves online separation and recycling of metal impurities, improves the purity of CPVC crushed material, and is beneficial for subsequent recycling. Attached Figure Description

Detailed Implementation

[0018] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely 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 inventive effort are within the scope of protection of the present invention. Example 1

[0019] A recycling device for CPVC pipes used in underground cables, such as Figure 1-7 As shown, it includes a positioning base 1 and a vibration transmission mechanism, a cleaning mechanism, and a recycling and crushing mechanism mounted on the positioning base 1. Two sets of positioning bases 1 are arranged in parallel. Positioning base 1 is an I-shaped base with transverse stiffening ribs. Both ends of positioning base 1 are fixedly installed with shock absorbers 2. The shock absorber 2 consists of a spring and a central damper. The top of the shock absorber 2 is fixedly installed with a mounting base 3 for the installation and fixation of the vibration transmission mechanism. The vibration transmission mechanism is fixedly installed on the top of the mounting base 3 and is used for the transmission and flipping of the pipe; The cleaning mechanism is positioned above the vibration transmission mechanism for cleaning pipelines. The recycling and crushing mechanism is installed on the right side of the vibrating conveyor mechanism and is used for receiving and crushing the pipeline. Example 2

[0020] like Figure 1-4As shown, based on this, the vibration transmission mechanism includes a vibration motor 4, a polarizing wheel 5, a disc spring connecting seat 6, a support side plate 7, a conveying top seat 8, a conveying roller 9, a driven bevel gear 10, a double bevel gear 11, a first motor 12, a bevel gear transmission wheel 13, a transmission belt 14, and a shock-absorbing spring 41. The vibration motor 4 is fixedly mounted on the side of the mounting base 3, and the polarizing wheel 5 is fixedly mounted on the output shaft of the vibration motor 4. A set of disc spring connecting seats 6 is mounted on each of the front and rear sides of the top surface of the mounting base 3. A support side plate 7 is fixedly mounted above the disc spring connecting seats 6, and a conveying top seat 8 is fixedly mounted on the top of the support side plate 7 via the disc spring connecting seats 6. The top conveyor 8 is an integrated frame structure with a sparse grid. The conveyor rollers 9 are installed in an array at an angle inside the top conveyor 8. A driven bevel gear 10 is fixedly installed at the front end of the conveyor rollers 9. A double bevel gear 11 is meshed on the side of the driven bevel gear 10. A first motor 12 is fixedly installed at the end of the double bevel gear 11. A bevel gear transmission wheel 13 is meshed on the front end of the double bevel gear 11. A transmission belt 14 is installed around the front end of the bevel gear transmission wheel 13. Three sets of parallel shock-absorbing springs 41 are installed in an array between two sets of disc spring connecting seats 6 at the upper end of the mounting base 3. The other end of the shock-absorbing springs 41 is fixed to the bottom of the top conveyor 8. The vibration motor 4 drives the polarizing wheel 5 to rotate, and the polarizing wheel 5 generates periodic vibrations that are transmitted to the mounting base 3 and the top conveyor seat 8. The support side plate 7 supports the conveyor seat 8 and also transmits vibrations. At the same time, the disc springs on the side of the disc spring connecting seat 6 that contact the support side plate 7 can dampen the support side plate 7 and prevent the support side plate 7 from damaging the mounting base 3. During the vibration process, the conveyor seat 8 will generate vibration force on the pipe conveyed on the top conveyor roller 9. At this time, the pipe will move towards the recovery pipe 22 by this force, and at the same time, it can shake off the dirt and other impurities on the surface. The outer wall of the pipe that has been buried underground for a long time will be covered with solidified yellow mud, cement lumps, and sand and gravel, which need to be cleaned.

[0021] The conveyor roller 9 is composed of multiple alternating and reverse-connected truncated cones, with adjacent truncated cones being symmetrically connected. The surfaces of the odd-numbered truncated cones are provided with friction threads. As the conveyor roller 9 is composed of alternating and symmetrically connected truncated cones, multiple "V"-shaped grooves are formed inside the conveyor roller 9, which facilitates the placement of the pipes to be recycled in these grooves for conveying. The conveyor roller 9 has a certain inclination angle with the conveying top seat 8. At the same time, the conveyor roller 9 is also periodically provided with friction threads inside, which can improve the friction between it and the pipe and prevent slippage. During the rotation of the conveyor roller 9, it simultaneously applies transmission and rolling forces to the pipe. While the pipe moves to the right, it also rotates inside the device, which facilitates the removal of mud and other impurities attached to the surface of the pipe and makes it easy to clean the conveyor roller 9.

[0022] Each even-numbered conveyor roller 9 has a drive assembly at its front end. The drive assembly consists of a driven bevel gear 10, a double bevel gear 11, a first motor 12, a bevel gear transmission wheel 13, and a transmission belt 14, which drives the conveyor roller 9 to rotate. The drive assemblies of adjacent even-numbered conveyor rollers 9 are connected in series via the transmission belt 14. The double bevel gear 11 consists of two bevel gears fixedly connected coaxially. One bevel gear meshes with the driven bevel gear 10, and the other bevel gear meshes with the bevel gear transmission wheel 13. The rotation direction of the bevel gear transmission wheel 13 is parallel to that of the conveyor top seat 8. The bevel gear transmission wheel 13 is an integral structure, having both a bevel gear section and a pulley section. During the driving process, the first motor 12 first drives the directly connected double bevel gear 11 to rotate. The double bevel gear 11 consists of two mutually fixed bevel gears with different cone angles. The device consists of bevel gears, one of which meshes with the bevel gear drive wheel 13, thus driving the bevel gear drive wheel 13 to rotate. The other bevel gear meshes with the driven bevel gear 10, thus driving the conveyor roller 9 to rotate via the driven bevel gear 10. The conveyor roller 9 conveys the pipe while simultaneously flipping it as it rotates. The front end of the bevel gear drive wheel 13 is a bevel gear meshing with the double bevel gear 11, and the rear end is a pulley integrated with the front bevel gear. Therefore, the bevel gear drive wheel 13 drives the next set of adjacent drive components to rotate via the drive belt 14 tightly attached to its outer periphery. Thus, the spaced conveyor rollers 9 rotate and convey within the device, and the drive mechanism drives the even set of conveyor rollers 9, applying a force to the rightward movement of the pipe while saving materials and reducing costs. Example 3

[0023] like Figure 2 and Figure 5 As shown, the cleaning mechanism includes a top rinsing frame 15, a spray pipe 16, a spray head 17, a cleaning brush 18, a bottom rinsing pipe 19, a flushing head 20, and a water channel 21. The top rinsing frame 15 is installed on the side of the mounting base 3. The mounting base 3 and the top rinsing frame 15 do not contact each other. The spray pipe 16 is fixedly installed on the top of the top rinsing frame 15. The spray head 17 is installed in a flow path at the bottom of the spray pipe 16. The cleaning brush 18, which is rotatably installed with the top rinsing frame 15, is installed below the spray head 17. The top surface of the mounting base 3 has an array of water channels 21. The bottom rinsing pipe 19 is fixedly installed on the side of the mounting base 3. The flushing head 20 is fixedly installed in a flow path on the side of the bottom rinsing pipe 19. The positions of the flushing head 20 and the water channel 21 correspond to each other. During the conveying process above the conveyor roller 9, some impurities on the surface are shaken off by the vibration of the vibration mechanism. At the same time, the surface of the pipe is washed by the cleaning brush 18 on the top and sprayed by the spray head 17 to wash away stubborn impurities, improve the cleanliness of the pipe, and prevent the pipe from being affected by excessive impurities during recycling. The cleanliness of the pipe is improved by the cooperation of the vibration mechanism and the cleaning mechanism. Meanwhile, the impurities washed off will fall to the bottom through the grid structure inside the conveyor top seat 8 and then be washed away.

[0024] The spray pipe 16 is installed in a U-shape on the top of the top flushing rack 15, and the spray heads 17 are installed in a parallel array at the bottom of the top flushing rack 15. When in use, water flows through the inside of the spray pipe 16 and is then evenly sprayed onto the pipe surface through the spray heads 17 in the bottom array. This lubricates the impurities on the pipe surface and washes them away with water pressure. At the same time, the pipe comes into contact with the cleaning brush 18 at the top during transport. The cleaning brush 18 further brushes away the impurities on the pipe surface, and the spray from the spray heads 17 washes away the impurities, thus cleaning the pipe.

[0025] The water channel 21 has a circular trough structure and is opened at an angle. The bottom of the end of the water channel 21 near the punch 20 is higher than the side away from the punch 20. Impurities flushed down from the pipe will fall above the mounting base 3. Then, the surface of the mounting base 3 is rinsed by the punch 20 installed on the left side of the mounting base 3, removing the impurities from the surface of the mounting base 3. The cleaning water flows inside the water channel 21, so that the impurities and water flow together inside the water channel 21. The water channel 21 has an inclined structure, which further avoids the accumulation of impurities. Example 4

[0026] like Figure 6-7As shown, based on this, the recycling and crushing mechanism includes a recycling pipe 22, a second motor 23, a drive gear set 24, a transmission roller 25, a third motor 26, a second gear set 27, a crushing cutter roller 28, a crushing channel 29, a slag suction bucket 30, a drive external gear 31, a drive gear 32, a fourth motor 33, a fixed cylinder 34, a bearing 35, a sector magnetic pole set 36, an inclined plate 37, a conveyor belt 38, a transmission pulley 39, and a crushing outlet 40. The recycling pipe 22 is installed on the right side of the conveying top seat 8, enclosing the right end of the conveying top seat 8. Two sets of transmission rollers 25 are installed inside the recycling pipe 22 near the port of the conveying top seat 8. A drive gear set 24, which drives the transmission rollers 25, is installed on the top of the recycling pipe 22. A second motor 23 is fixedly installed on the top of the drive gear set 24. A crushing cutter roller 28 is installed inside the recycling pipe 22 to the right of the transmission roller 25. A second gear set is installed on the top of the crushing cutter roller 28. 27. The second gear set 27 is driven by the third motor 26 at the top. A slag suction bucket 30 is installed on the right side of the crushing roller 28. A drive external gear 31 is fixedly installed at the front end of the slag suction bucket 30. A drive gear 32 is meshed on the side of the drive external gear 31. The drive gear 32 is installed by the fourth motor 33 at the front end. Three sets of fan-shaped magnetic pole groups 36 with concentric circles are installed inside the slag suction bucket 30. The three sets of fan-shaped magnetic pole groups 36 are fixed to the fixed cylinder 34 inside. The fixed cylinder 34 is fixed to the recovery pipe 22. The slag suction bucket 30 is rotatably connected to the fixed cylinder 34 through a bearing 35 installed in the center. The bearing 35 is located in the gap between the fan-shaped magnetic pole groups 36. An inclined plate 37 fixed to the recovery pipe 22 is installed on the right side of the slag suction bucket 30. A conveyor belt 38 is installed below the right side of the recovery pipe 22. The left and right sides of the conveyor belt 38 are driven by transmission pulleys 39 that are tightly installed. A crushed material outlet 40 is installed at the right end of the recovery pipe 22.

[0027] The drive gear set 24 consists of four sets of meshing gears. The transmission rollers 25 form a rotating structure through the drive gear set 24. The two sets of transmission rollers 25 rotate in opposite directions. The second motor 23 drives the drive gear set 24 to rotate. The drive gear set 24 consists of four gears, so the two sets of transmission rollers 25 can have different rotation directions. After the cleaned pipe is driven into the recycling pipe 22, the transmission rollers 25 continue to apply a force to the right to make the pipe contact the crushing roller 28 and then be crushed and recycled by the crushing roller 28.

[0028] The slag suction bucket 30 forms a rotating structure through the cooperation between the drive external gear 31 and the drive gear 32. The sector-shaped magnetic pole group 36 is a sector-shaped structure missing on the side near the inclined plate 37. The inclined plate 37 is fixedly and inclinedly installed with the recovery pipe 22. The side of the inclined plate 37 near the slag suction bucket 30 is installed at a higher height. During use, the pipe after being crushed by the crushing roller 28 will enter the upper part of the right conveyor belt 38, and then be driven and conveyed by the transmission pulleys 39 on both sides of the conveyor belt 38. The crushed pipe fragments are conveyed. During the conveying process, the fragments will come into contact with the slag suction bucket 30. The slag suction bucket 30 generates magnetic force through the internal sector-shaped magnetic pole group 36 to absorb, collect and sort the iron slag and other materials in the fragments, thereby improving the purity of the fragments. After the slag suction bucket 30 adsorbs the iron slag in the crushed material, the fourth motor 33 drives the external drive gear 31 to rotate inside the device through the drive gear 32. The rotation of the drive gear 32 drives the iron slag outside to rotate. Since the internal fan-shaped magnetic pole group 36 has a fan-shaped structure, the magnetic force will disappear when the slag suction bucket 30 rotates to the missing part of the fan-shaped magnetic pole group 36. Since the missing part of the fan-shaped magnetic pole group 36 matches the position of the inclined plate 37, the iron slag that falls after the magnetic force disappears will fall just above the inclined plate 37. The inclined plate 37 and the recovery pipe 22 are installed at an angle, so the falling iron slag will slide to the right and be discharged for recycling. Next, the crushed material in the pipeline after being sorted is conveyed by the conveyor belt 38 and discharged from the crushed material outlet 40 for recycling.

[0029] Working principle: First, the pipe is placed above the conveyor roller 9 for conveying. At this time, the first motor 12 drives the directly connected double bevel gear 11 to rotate. The double bevel gear 11 consists of two bevel gears with different cone angles that are fixed to each other. One of them meshes with the bevel gear transmission wheel 13, so the double bevel gear 11 drives the bevel gear transmission wheel 13 to rotate. The other meshes with the driven bevel gear 10, so the double bevel gear 11 drives the conveyor roller 9 to rotate through the driven bevel gear 10. When the conveyor roller 9 rotates, it conveys the pipe and flips it at the same time. At the same time, the front end of the bevel gear transmission wheel 13 is a bevel gear that meshes with the double bevel gear 11, and the rear end is a pulley that is integrated with the front bevel gear. Therefore, the bevel gear transmission wheel 13 drives the next set of adjacent drive components to rotate through the transmission belt 14 that is tightly attached to its outer periphery. Thus, the spaced conveyor rollers 9 rotate and convey the pipe inside the device. The drive mechanism drives the even set of conveyor rollers 9, applying a force to the right to the pipe, which can save materials and reduce costs. The vibrating motor 4 drives the polarizing wheel 5 to rotate, and the periodic vibration of the polarizing wheel 5 is transmitted to the mounting base 3 and the top conveyor 8. The support side plate 7 supports the conveyor 8 and also transmits vibration. At the same time, the disc springs on the side of the disc spring connecting seat 6 that contact the support side plate 7 can dampen the vibration of the support side plate 7 and prevent the support side plate 7 from damaging the mounting base 3. During the vibration of the conveyor 8, the conveyor 8 will generate a vibration force on the pipe conveyed on the top conveyor roller 9. At this time, the pipe will move towards the recovery pipe 22 by this force. While moving, it can also shake off the dirt and other impurities on the surface. Water flows through the inside of the spray pipe 16 and is then evenly sprayed onto the pipe surface through the spray head 17 at the bottom array. This lubricates the impurities on the pipe surface and washes them away with water pressure. At the same time, the pipe will come into contact with the cleaning brush 18 at the top during the transmission process. The cleaning brush 18 further brushes off the impurities on the pipe surface, and the spray head 17 washes away the impurities. Pipes that have been buried underground for a long time will have solidified yellow mud, cement lumps, and sand and gravel on their outer walls, which need to be cleaned. After being cleaned, the pipe is conveyed into the recovery pipe 22. The transmission roller 25 applies a force to the right, causing the pipe to contact and be crushed by the crushing roller 28. The crushed pipe then enters the upper part of the right-side conveyor belt 38, where it is driven by the transmission pulleys 39 on both sides to transport the crushed pipe fragments. During this transport, the fragments come into contact with the slag suction bucket 30. The slag suction bucket 30 generates magnetic force through its internal fan-shaped magnetic pole group 36, collecting and sorting the iron slag and other contaminants from the fragments to improve their purity. After the slag suction bucket 30 absorbs the iron slag, the fourth motor... 33 drives the external drive gear 31 to rotate inside the device via the drive gear 32. The rotation of the drive gear 32 drives the external iron slag to rotate. Since the internal sector magnetic pole group 36 has a sector structure, the magnetic force will disappear when the slag suction bucket 30 rotates to the missing part of the sector magnetic pole group 36. Since the missing part of the sector magnetic pole group 36 matches the position of the inclined plate 37, the iron slag that falls after the magnetic force disappears will fall just above the inclined plate 37. The inclined plate 37 and the recovery pipe 22 are installed at an angle, so the falling iron slag will slide to the right and be discharged for recycling.
