[0002] The outer sheath overhead insulated pipe is a device commonly used for pipeline insulation. The inner layer is the working pipe, which is used to transport media such as hot water, steam, etc. The middle layer is the insulation material, and the outermost layer is the outer sheath. During the production process of the outer sheath overhead insulated pipe, a large amount of waste will be generated, such as scraps produced by cutting, unqualified products, etc.

[0003] At present, the outer sheath overhead insulation pipe needs to be trimmed after production is completed. If the waste generated during the trimming process is not collected and treated in a timely and effective manner, it will not only take up space, but also affect the cleanliness of the production environment. Therefore, it is necessary to collect the waste generated in the production process of the outer sheath overhead insulation pipe. There are two main existing waste collection methods. One is to collect and treat the waste generated in the production of the outer sheath overhead insulation pipe as garbage.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the present invention is used, the waste generated by trimming the outer protective skin overhead insulation pipe is transported to the inside of the processing box through the baffle conveyor belt, and the crushing and paving mechanism crushes it so that it falls into small pieces on the storage table. Then, under the action of the cylinder, the storage table drives the waste to fall onto the classification table.

[0018] 2. When the present invention is used, after the waste is completely classified in the classification trough, the hydraulic cylinder on the horizontal plate is started to push the pressure plate in the classification trough to move downward. The pressure plate that moves downward can compress the classified waste into standard blocks. Then the third cylinder is started to push the third connecting plate to move to the left, which drives the collection shell to move to the left as a whole. The limiting plate inserted on the left side of the classification trough is integrated with the horizontal plate and will not move. Therefore, during the movement of the classification trough, the compressed waste blocks inside will be blocked by the limiting plate and eventually fall to the outside, which makes it convenient to collect materials. In addition, the compressed waste blocks greatly increase the difficulty of subsequent recycling and processing, and are highly practical.

[0019] 3. When the present invention is used, the waste will first fall into the transmission belt below after being crushed by the crushing roller, and the second pulley connected to one of the second gears through the shaft will rotate along with it, and drive the first pulley to rotate slowly through the synchronous belt. After the first pulley rotates, it will drive one of the rollers to rotate through the shaft. At this time, the cooperation of the two rollers will drive the transmission belt to rotate slowly, and the crushed material above will be transported to one side and fall onto the storage table below. When the brush on the surface of the transmission belt follows the transmission belt to move to the bottom, it will scrape the waste on the storage table, so that the waste gradually forms a spreading state. When the waste is flattened, the thickness of the waste accumulation can be reduced, which greatly reduces the difficulty of subsequent image acquisition and ensures the accuracy of waste classification.

The classification mechanism 6 includes a material receiving platform 601, and three classification chutes 602 inclined to the lower left are opened on the top of the material receiving platform 601. The front and rear outer surfaces of the material receiving platform 601 are fixedly connected to the cylinder seat 603 near the bottom, and the outer surface of the cylinder seat 603 is installed with a third cylinder 604 with a telescopic rod facing left, and the telescopic ends of the two third cylinders 604 are fixedly connected to the third connecting plate 605, and the outer surfaces of the two third connecting plates 605 are fixedly connected with a collection shell 606.Three classification slots 607 are provided inside the collection shell 606.

A connection frame 82 is fixedly connected to the front surface of the classification platform 1 near the bottom. A feeding channel 8 is fixedly connected to the front surface of the connection frame 82. The feeding channel 8 is bent and the outer surface near the top is connected to the top of the processing box 3. A baffle-type conveyor belt 81 is installed between the inner surface walls of the feeding channel 8.

[0033] In this embodiment, the inner working channel of the outer protective skin overhead insulation pipe adopts a composite, high-temperature resistant insulation material, and uses an outer protective hollow aluminum shell, and is cast in the aluminum shell, so that the inner steel pipe can achieve the insulation effect when conveying steam, and at the same time, flame-retardant polyurethane is cast and foamed on site to fill it in the hollow aluminum shell, which can effectively increase the energy saving and insulation of the insulation pipe by 40-60%. After production is completed, it is necessary to trim the excess inner steel pipe at the corners and ends, the middle layer of polyurethane material and the outer layer of aluminum. When the waste generated after trimming is collected, the baffle conveyor belt 81 in the feeding channel 8 will transport it from a low place to a high place and then fall into the processing box 3 from above. The baffle conveyor belt 81 is an existing mature technology, and its conveying A baffle is provided on the surface of the belt to effectively prevent the waste from slipping, and the external motor drives the transmission roller inside the conveyor belt to drive the baffle conveyor belt 81 to operate. The loading channel 8 is bent, and its bottom is in the same plane as the bottom of the classification table 1 and contacts the bottom surface. The position below its top is connected to the top of the processing box 3 and is surrounded, which can ensure that the waste falls into the processing box 3. The waste falling into the processing box 3 will be above the crushing roller 401. At this time, after starting the first motor 34 on the motor frame 32, one of the first gears 33 will be driven to rotate. At this time, the first gear 33 will drive the adjacent second gear 402 to rotate synchronously. At this time, the two meshing second gears 402 will rotate in the opposite direction. The second gears 402 located on both sides of the first gear 33 will rotate in the opposite direction. 402 will rotate in the same direction, and the crushing roller 401 connected to the second gear 402 and adjacent will squeeze and crush the waste. The crushing roller 401 with a slightly larger spacing will transport it to the right to the top of the next crushing roller 401 for crushing. The waste that is difficult to crush will eventually be transported to the far right for accumulation, so that it is convenient to take it out for separate treatment. After the waste is crushed, it falls to the storage table 25 below. The first cylinder 2 is started to cooperate with the first connecting plate 21 to drive the crushed waste to move downward and then fall on the top of the classification table 1. The enclosure 12 plays a role in shielding the surroundings of the storage table 25. Then, the second cylinder 501 in the installation slot 11 is started to pull the second connecting plate 502 backward, and the L-shaped bracket 503 connected to the second connecting plate 502 will move backward synchronously and The CCD industrial camera 504 is moved to the position just above the storage table 25, and then the CCD industrial camera 504 captures the waste and collects image data, and compares the color features, shape features and texture features of the waste image with the stored image information features, and analyzes and processes the type and position information of the waste through the trained model and algorithm in the external PLC controller, and then controls the mechanical arm 23 to drive the vacuum suction rod 24 to adsorb and fix the waste according to the image information, and then puts the waste into different classification chutes 602 inside the receiving table 601 according to the type of waste. Under the action of gravity, the waste will slide down to the different classification slots 607 inside the collection shell 606 to complete the classification and collection. The equipment has a high degree of automation.The production waste of the outer protective skin overhead insulation pipe can be crushed and classified and collected, which is highly efficient and effectively avoids the problem of resource waste. The mounting table 22 is mainly used to carry the mechanical arm 23. The receiving table 601 and the classification table 1 are connected to form a whole through the mounting table 22 and the outer shell of the third cylinder 604. The classification table 1 and the processing box 3 are mainly used to connect the steel 13 and bolts for fixed connection.

[0034] Embodiment 2: Figure 2-Figure 4 and Figure 7 As shown, two rollers 403 are symmetrically mounted for rotation near the middle between the front and rear inner walls of the processing box 3, the second pulley 407 and the first pulley 406 are both rotatably mounted on the rear surface of the processing box 3, the transmission belt 404 is sleeved on the outer surfaces of the two rollers 403, and a plurality of brushes 405 are equidistantly mounted on the outer surface of the transmission belt 404. The center of the front surface of the second pulley 407 is fixedly connected to the center of the rear surface of one of the second gears 402 via an axis, the center of the front surface of the first pulley 406 is fixedly connected to the center of the rear surface of one of the rollers 403 via an axis, and a laser beam sensor 31 is installed near the bottom of the front and rear inner walls of the processing box 3, and the laser beam sensor 31 is located below the transmission belt 404.

[0035] In this embodiment, after the waste is crushed by the crushing roller 401, it will first fall into the transmission belt 404 below, and the second pulley 407 connected to one of the second gears 402 through the shaft will rotate accordingly, and drive the first pulley 406 to rotate slowly through the synchronous belt 408. After the first pulley 406 rotates, it will drive one of the rollers 403 to rotate through the shaft. At this time, the cooperation of the two rollers 403 will drive the transmission belt 404 to rotate slowly, and the crushed materials above will be transported to one side and fall onto the storage table 25 below. When the brush 405 on the surface of the transmission belt 404 follows the transmission belt 404 to move to the bottom, it will scrape the waste on the storage table 25, so that the waste is gradually removed. Gradually forming a spreading state, when there is a lot of waste, the first cylinder 2 can be started to cooperate with the first connecting plate 21 to drive the storage table 25 to move downward a suitable distance inside the processing box 3 to avoid excessive accumulation of waste. After the waste is spread, the transmitter in the laser beam sensor 31 continues to emit a laser of a specific wavelength and power, and the receiver is responsible for receiving it. When the receiver continues to be unable to receive a complete light signal, the first cylinder 2 is controlled to drive the storage table 25 to continue to descend. When the receiver receives a complete light signal, the surface waste is flattened. When the waste is flattened, the thickness of the waste accumulation can be reduced, which greatly reduces the difficulty of subsequent image acquisition, ensures the accuracy of waste classification, and the operation of the transmission belt 404 does not require additional electrical components.

[0036] Embodiment 3: Figure 1 , Figure 2 , Fig. 9 and Fig.10 As shown, the three compression mechanisms 7 all include a transverse plate 701, a longitudinal plate 702 is fixedly connected to the right surface of the transverse plate 701, the right surface of the longitudinal plate 702 is fixedly connected to a position near the top of the left surface of the material receiving platform 601, the three longitudinal plates 702 respectively correspond to the positions of the three classification chutes 602, a hydraulic cylinder 705 is fixedly installed on the top of the transverse plate 701, the telescopic end of the hydraulic cylinder 705 slides through the top of the transverse plate 701 and extends to the bottom, the telescopic end of the hydraulic cylinder 705 is fixedly connected to a pressing plate 706, the bottom of the transverse plate 701 is fixedly connected to a limiting plate 703 near the left edge, the outer surface of the limiting plate 703 is fitted with the inner surface wall of the classification groove 607, a reinforcing rib 704 is fixedly connected between the top of the transverse plate 701 and the left surface of the longitudinal plate 702, a reinforcing rod 707 is fixedly connected to the top of the transverse plate 701 near the left edge, and the right end of the reinforcing rod 707 is fixedly connected to the left surface of the material receiving platform 601.

[0037] After the waste is completely classified in the classification trough 607, the hydraulic cylinder 705 on the horizontal plate 701 is started to push the pressure plate 706 in the classification trough 607 to move downward. The pressure plate 706 that moves downward can compress the classified waste into standard blocks. Then, the third cylinder 604 is started to push the third connecting plate 605 to move to the left, which plays a role in driving the collection shell 606 to move to the left as a whole. The limiting plate 703 inserted in the left side of the classification trough 607 is integrated with the horizontal plate 701 and will not move. Therefore, during the movement of the classification trough 607, the compressed waste blocks inside will be blocked by the limiting plate 703 and eventually fall to the outside, which makes it convenient to collect materials, and the compressed waste blocks greatly increase the difficulty of subsequent recycling and processing, and are highly practical. The longitudinal plate 702 is mainly used to connect the horizontal plate 701 and the receiving platform 601, and the reinforcing rib 704 is used to improve the connection strength between the longitudinal plate 702 and the horizontal plate 701. The reinforcing rod 707 plays an effect of further improving the connection strength between the longitudinal plate 702 and the horizontal plate 701.

[0038] The effect and working principle achieved by the entire mechanism are as follows: the inner working channel of the outer protective skin overhead insulation pipe adopts composite, high-temperature resistant insulation material, and utilizes the outer protective hollow aluminum shell, and is cast in the aluminum shell, so that the inner steel pipe can achieve the insulation effect when conveying steam, and at the same time, flame-retardant polyurethane is cast and foamed on site to fill it in the hollow aluminum shell, which can effectively increase the energy-saving and heat-insulating properties of the insulation pipe by 40-60%. After production is completed, it is necessary to trim the excess inner steel pipe at the corners and ends, the middle layer of polyurethane material and the outer layer of aluminum skin. When the waste generated after trimming is collected, the baffle conveyor belt 81 in the feeding channel 8 will transport it from low to high and then fall into the processing box 3 from above. The waste falling into the processing box 3 will The first gear 33 drives the adjacent second gear 402 to rotate synchronously. At this time, the meshed second gears 402 rotate in the opposite direction. The second gears 402 on both sides of the first gear 33 rotate in the same direction. The crushing rollers 401 connected with the second gear 402 and adjacent to each other squeeze and crush the waste. After the crushed waste falls to the storage table 25 below, the first cylinder 2 is started to cooperate with the first connecting plate 21 to drive the crushed waste to move downward and fall on the top of the classification table 1. The enclosure 12 plays a role in shielding the surrounding of the storage table 25. Then, the second cylinder 501 in the installation slot 11 is started to move backward. Pull the second connecting plate 502, the L-shaped bracket 503 connected to the second connecting plate 502 will move backward synchronously and move the CCD industrial camera 504 to the position directly above the storage table 25, and then the CCD industrial camera 504 will capture the waste and collect image data, and compare the color features, shape features and texture features of the waste image with the stored image information features and analyze and process the type and position information of the waste through the trained model and algorithm in the external PLC controller, and then control the robot arm 23 to drive the vacuum suction rod 24 to adsorb and fix the waste according to the image information, and then put the waste into different classification chutes 602 inside the receiving table 601 according to the type of waste, and the waste will slide to the lower place under the action of gravity. Classification and collection are completed in different classification slots 607 inside the collection shell 606. The equipment has a high degree of automation and can crush and classify the production waste of the external protective skin overhead insulation pipe. It has high efficiency and effectively avoids the problem of resource waste. When the waste is completely classified in the classification slot 607, the hydraulic cylinder 705 on the horizontal plate 701 is started to push the pressure plate 706 in the classification slot 607 to move downward. The pressure plate 706 after moving downward can compress the classified waste into standard blocks. Then the third cylinder 604 is started to push the third connecting plate 605 to move to the left, which plays a role in driving the collection shell 606 to move to the left as a whole. The limiting plate 703 inserted on the left side of the classification slot 607 is integrated with the horizontal plate 701 and will not move.Therefore, during the movement of the classification trough 607, the waste blocks compressed inside will be blocked by the limiting plate 703 and eventually fall to the outside, which makes it convenient to collect materials, and the compressed waste blocks greatly increase the difficulty of subsequent recycling and treatment, and are highly practical. In addition, after the waste is crushed by the crushing roller 401, it will first fall into the transmission belt 404 below, and the second pulley 407 connected to one of the second gears 402 through the shaft will follow the rotation, and drive the first pulley 406 to rotate slowly through the synchronous belt 408, and the first pulley 406 rotates After the movement, one of the rollers 403 will be driven to rotate through the shaft, and at this time, the cooperation of the two rollers 403 will drive the transmission belt 404 to rotate slowly, and the crushed materials above will be transported to one side and fall onto the storage table 25 below. When the brush 405 on the surface of the transmission belt 404 follows the transmission belt 404 to move downward, it will scrape the waste on the storage table 25, so that the waste gradually forms a spreading state. When the waste is flattened, the thickness of the waste accumulation can be reduced, which greatly reduces the difficulty of subsequent image acquisition and ensures the accuracy of waste classification.
