Description

Technical Field

[0001] The invention relates to the technical field of heat shrink tube crushing and recycling, in particular to waste material recycling equipment for batch head heat shrink tube production. Background Art

[0002] In the production process of batch head heat shrink tubes, a large amount of waste is generated. These wastes are usually recycled by crushing and secondary processing. Before crushing, the waste is often at a high temperature due to its own residual heat or environmental factors. Direct crushing can easily cause the thermoplastic heat shrink tube waste to stick and deform during the crushing process, seriously affecting the uniformity and particle size quality of the crushing. In addition, during the crushing process, due to frictional heat generation, if it cannot be cooled in time, the physical properties of the waste will change, reducing the quality of the crushed material.

[0003] In addition, the traditional pulverizing equipment has a fixed structure of pulverizing blades, and its angle cannot be flexibly adjusted according to the characteristics of the waste and the pulverizing requirements. This can easily lead to problems such as incomplete pulverization, excessive energy consumption, and rapid wear of the pulverizing blades, thereby reducing the pulverizing efficiency and stability of the entire waste recycling equipment, and failing to meet the needs of high-quality waste recycling and processing.

[0015] The present invention provides a waste recycling device for batch head heat shrink tube production, which has the following beneficial effects: 1. The present invention transports the liquid nitrogen in the liquid nitrogen storage tank to the inside of the diversion pipe 1 through the connecting pipe 1, and sprays it to the periphery of the heat shrink tube to cool the heat shrink tube. At the same time, when the liquid nitrogen contacts the object with oil stains, some components in the oil stains, such as long-chain hydrocarbons in grease, will become brittle in such an extremely low temperature environment. During the vibration transportation process, they can be peeled off from the surface of the heat shrink tube along with the liquid nitrogen, which is beneficial to not needing to clean the crushed particles after crushing, and is beneficial to improving the efficiency of crushing and recycling the heat shrink tube.

[0016] 2. The present invention delivers the liquid nitrogen carrying oil pollution to the upper end of the evaporation bin through the delivery valve and the connecting bellows 1, and drips to the inner bottom of the evaporation bin after being filtered by the filter screen, and starts the heating plate to heat the liquid nitrogen, so that its temperature rises to above -196°C to cause gasification, and after gasification, it enters the interior of the wind bin 1 through the connecting pipe 2, drives the wind wheel 1 to rotate, and then drives the small gear to rotate through the driving shaft, and then drives the collecting shaft to rotate through the large gear, and then drives the filter screen to collect to the periphery of the collecting shaft, so as to realize continuous filtering of the liquid nitrogen mixed with oil pollution, which is beneficial to the later use of the gasified low-temperature clean nitrogen.

[0017] 3. In the present invention, when the batch head heat shrink tube cleaned by liquid nitrogen is transported to the storage pool by connecting bellows 2 for storage, the low-temperature nitrogen inside the wind wheel 1 is transported to the inner lower part of the storage pool by connecting pipe 3 and shunt pipe 2, so as to continuously cool the heat shrink tube stored and waiting to be crushed and recovered. The low-temperature nitrogen will cause the heat shrink tube to become brittle, so that when the quantitative control valve is opened and transported to the crushing bin for crushing by the crushing knife, the heat shrink tube can be more easily crushed into particles for recovery. At the same time, it is beneficial to prevent the heat shrink tube from being stuck and unable to be crushed due to the temperature rise of the crushing knife due to continuous crushing during the later crushing.

[0018] 4. The present invention cools the heat shrink tube by the low-temperature nitrogen in the storage tank, and then transports it to the inner upper part of the installation bin through the connecting pipe 4, enters the interior of the wind bin 2 to blow the wind wheel 2 to rotate, and then drives the corrugated driving disk to rotate through the driving tube, and then drives the driving seat to slide up and down inside the limit seat, and drives the rotating disk to reciprocate through the driving rod, and finally drives the crushing knife to perform reciprocating adjustment motion, so that all the crushing knives can keep different angles to cut the heat shrink tube in the process of crushing the heat shrink tube, thereby improving the crushing effect and efficiency.

[0019] 5. In the present invention, when the air groove 1 in the rotating disk rotates and is aligned with the air hole 3, the low-temperature nitrogen that enters the limit box through the driving tube and the air hole 1 at the upper end can enter the interior of the air groove 2 through the air groove 1, and then be ejected from the air groove 3 and the air hole 2. This not only realizes intermittent cooling of the crushing knife during the crushing process to avoid the crushing knife from heating up, but also can blow the crushed particles at the rear end of the crushing knife at this location into disorder, which is beneficial to the effect and efficiency of subsequent crushing.

[0020] 6. The present invention transports the remaining gas in the wind bin two to the diversion pipe three through the connecting pipe five, and transports the low-temperature nitrogen to the inner bottom wall of the crushing bin through the gas outlet nozzle at the upper end of the diversion pipe three. This not only achieves continuous cooling of the heat shrink tube particles during the crushing process, which is beneficial to improving the crushing effect and efficiency, but also can further blow the heat shrink tube particles into disorder, so that the heat shrink tube can be completely crushed and recovered.

Not only does it realize the continuous cooling of the heat shrink tube particles during the crushing process, which is beneficial to improving the crushing effect and efficiency, but also can further blow the heat shrink tube particles in a disorderly manner, so that the heat shrink tube can be completely crushed and recovered. After the crushing is completed, the discharge valve at the lower end of the crushing bin 201 is opened, and the crushed heat shrink tube particles can be lowered into the recovery pool 3 for storage.

[0039] Working principle: First, the heat shrink tube that needs to be crushed and recovered is gradually fed into the interior of the vibration bin 101 through the feed port at the upper end of the vibration bin 101 by the conveyor belt, and the vibration motor 103 is started to drive the vibration bin 101 to vibrate, so that the heat shrink tube is vibrated and turned over at the upper end of the bulk plate 102 and transported to the right, and the liquid nitrogen delivery pump 107 is started, wherein 1077 adopts an intelligent liquid nitrogen pump as disclosed in publication number CN111188751A, and the liquid nitrogen in the liquid nitrogen storage tank 108 is transported to the interior of the diversion pipe 105 through the connecting pipe 106, and sprayed to the periphery of the heat shrink tube to cool the heat shrink tube. At the same time, when the liquid nitrogen comes into contact with an object with oil stains, some components in the oil stains, such as long-chain hydrocarbons in grease, In this extremely low temperature environment, embrittlement will occur. During the vibration transportation process, it can be peeled off from the surface of the heat shrink tube with the liquid nitrogen, which is beneficial to not having to clean the crushed particles after crushing, and is beneficial to improving the efficiency of heat shrink tube crushing and recovery. The liquid nitrogen carrying oil pollution is transported to the upper end of the evaporation bin 1011 through the delivery valve 109 and the connecting bellows 1010, and is filtered by the filter screen 1017 and drips to the inner bottom of the evaporation bin 1011. The heating plate 1012 is started to heat the liquid nitrogen to raise its temperature to above -196°C to gasify. After gasification, it enters the interior of the wind bin 1019 through the connecting pipe 1021, drives the wind wheel 1020 to rotate, and then drives the small gear 1018 to rotate through the driving shaft 1015, and then drives the large gear 1018 to rotate. 1025 drives the collection shaft 1024 to rotate, and then drives the filter screen 1017 to collect to the periphery of the collection shaft 1024, so as to continuously filter the liquid nitrogen mixed with oil, which is beneficial to the later use of gasified low-temperature clean nitrogen. When the batch head heat shrink tube cleaned by liquid nitrogen is transported to the storage tank 1027 by connecting bellows 2 1026 for storage, the low-temperature nitrogen inside the wind wheel 1020 is transported to the inner lower part of the storage tank 1027 by connecting pipe 3 1022 and shunt pipe 2 1028, so as to continuously cool the heat shrink tube stored and waiting for crushing and recycling. The low-temperature nitrogen will make the heat shrink tube brittle, so that it can be more easily broken when it is transported to the crushing bin 201 by the crushing knife 21 after opening the quantitative control valve 1029. The heat shrink tube is crushed into particles for recycling. At the same time, it is beneficial to prevent the temperature of the crushing knife 2021 from rising due to continuous crushing during the later crushing, which may cause the heat shrink tube to be stuck and unable to be crushed. After the heat shrink tube is cooled and embrittled, the quantitative control valve 1029 is started to transport the heat shrink tube to the inside of the crushing bin 201, and the motor 202 is started to drive the large pulley 205 to rotate through the small pulley 203 and the transmission belt 204, and then drive all the crushing knives 2021 to rotate through the rotating tube 2029 to crush and recycle the heat shrink tube. At the same time, after the low-temperature nitrogen in the storage tank 1027 cools the heat shrink tube, it is transported to the inner upper part of the installation bin 206 through the connecting pipe four 2026, and enters the inside of the wind bin two 208 to blow the wind wheel two 209 to rotate.Then, the corrugated driving disk 2012 is driven to rotate through the driving tube 2010, and then the driving seat 2013 is driven to slide up and down inside the limiting seat 2015, and the rotating disk 2017 is driven to reciprocate through the driving rod 2016, and finally the crushing knife 221 is driven to perform reciprocating adjustment movement, so that all the crushing knives 221 can keep different angles to cut the heat shrink tube in the process of crushing the heat shrink tube, thereby improving the crushing effect and efficiency. At the same time, when the air groove 1 2018 in the rotating disk 2017 rotates and aligns with the air hole 3 2025, the low-temperature nitrogen gas entering the limiting box 2024 through the driving tube 2010 and the air hole 1 2011 at the upper end can enter the interior of the air groove 2 2020 through the air groove 1 2018, and then be ejected by the air groove 3 2022 and the air hole 2 23, which not only achieves the crushing During the process, the crushing blade 2021 is intermittently cooled to prevent the crushing blade 2021 from heating up, and at the same time, the crushed particles at the rear end of the crushing blade 2021 can be blown in disorder, which is beneficial to the subsequent crushing effect and efficiency. The remaining gas in the wind bin 208 is transported to the diverter pipe 3 2028 through the connecting pipe 5 2027, and the low-temperature nitrogen is transported to the inner bottom wall of the crushing bin 201 through the gas outlet nozzle at the upper end of the diverter pipe 3 2028. This not only realizes the continuous cooling of the heat shrink tube particles during the crushing process, which is beneficial to improving the crushing effect and efficiency, but also can further blow the heat shrink tube particles in disorder, so that the heat shrink tube can be completely crushed and recycled. After the crushing is completed, the discharge valve at the lower end of the crushing bin 201 is opened, and the crushed heat shrink tube particles can be placed in the recovery pool 3 for storage.
