Description

Technical Field

[0001] The present application relates to the field of power accessories, and in particular to a production device for power cold shrink tubes. Background Art

[0002] Electric power cold shrink tubing is a tubular cable accessory that uses cold shrink technology. It is mainly used for insulation, sealing and protection of the terminal heads and joints of power cables. In recent years, as the requirements for safety and reliability of power systems continue to increase, the demand for electric power cold shrink tubing has also increased year by year. However, the production process of cold shrink tubing involves many process links, among which the vulcanization process is particularly critical and directly affects the performance and quality of the product.

[0003] In the existing cold shrink tube production process, the method usually adopted is to first mix the raw materials in a specific proportion, then extrude them through an extruder and a mold, then transport them to the vulcanization module for vulcanization treatment, and finally cool them through the cooling module to complete the entire production process. During the vulcanization process, common equipment configurations include heating devices, air supply devices, and cooling devices. These devices can effectively control the vulcanization temperature and time to ensure uniform vulcanization of the product.

[0004] However, in the actual production process, the vulcanization module often produces a certain amount of waste gas, which contains oil mist and particulate matter. Since the feed and discharge ports of the vulcanization module are usually not completely sealed, the waste gas is easy to leak from these locations, thus affecting the air quality of the workshop. This waste gas leakage not only threatens the health of operators, but also may pollute the environment, so it is urgent to take measures to improve it. Summary of the invention

[0005] In order to reduce exhaust gas leakage during the vulcanization process, the present application provides an electric cold shrink tube production device.

[0006] The present application provides an electric cold shrink tube production device that adopts the following technical solution:

[0007] A production device for electric power cold shrink tubes includes a mixing module, an extrusion module, a vulcanization module and a cooling module. The vulcanization module includes a box body, a heating rod is arranged inside the box body, a lower heat cover is arranged below the heating rod, and the lower heat cover is connected to an air supply fan and an air supply duct. An upper heat cover is arranged above the heating tube, the upper heat cover is connected to the air supply duct, the upper heat cover is connected to an air outlet fan and an air outlet duct, and the air outlet duct extends out of the box body and is connected to an exhaust gas treatment module.

[0008] By adopting the above technical solution, the waste gas generated during the vulcanization process can be effectively collected and treated, and the waste gas can be prevented from leaking from the feed or discharge port of the vulcanization module, thereby significantly improving the air quality in the workshop. Specifically, the air supply fan pumps the heat and waste gas from the heating rod into the upper heat cover through the air supply duct. The waste gas in the upper heat cover flows out of the box through the air outlet duct under the action of the air outlet fan and enters the waste gas treatment module for treatment, ensuring that the box maintains a negative pressure state throughout the process, so that the air flow direction is always from the outside to the inside of the box, effectively avoiding waste gas leakage.

[0009] Preferably, a plurality of guide plates are arranged inside the upper heat cover, the guide plates are divided into two groups, and the two groups of guide plates are respectively located on two opposite inner side walls of the upper heat cover, and the two groups of guide plates are staggered.

[0010] By adopting the above technical solution, the guide plates arranged inside the upper heat cover can effectively guide the airflow direction, so that the exhaust gas is fully mixed and evenly distributed in the upper heat cover, improving the collection efficiency of the exhaust gas, reducing the residence time of the exhaust gas in the upper heat cover, and reducing the risk of exhaust gas leakage. At the same time, the staggered arrangement between the two sets of guide plates can further enhance the turbulence of the airflow, thereby making the temperature of each part of the upper heat cover more uniform.

[0011] Preferably, the upper heat shield comprises a pair of movable shield bodies, the two groups of guide plates are respectively connected to the inner walls of the corresponding movable shield bodies, and the box body is provided with two adjustment drives respectively used to drive the two movable shield bodies to move so as to adjust the staggered degree of the guide plates.

[0012] By adopting the above technical solution, the design of the mobile cover allows the degree of staggering of the guide plates to be flexibly adjusted, so as to better adapt to different process requirements and improve the efficiency of waste gas treatment. At the same time, the setting of the adjustable drive mechanism ensures the precise control of the guide plate position, further improving the stability and reliability of the equipment.

[0013] Preferably, guide rollers are rotatably provided at the bottom of several guide plates.

[0014] By adopting the above technical solution, the guide rollers arranged at the bottom of the guide plate can effectively reduce the friction that the cold shrink tube may be subjected to during the transmission process, thereby improving the transmission efficiency and stability of the cold shrink tube.

[0015] Preferably, a transition box is provided inside the box body, the air supply duct is connected to the transition box, and the transition box is connected to the upper heat shield through a transition pipe.

[0016] By adopting the above technical solution, the air supply duct is connected to the transition box, and the transition box is connected to the upper heat cover through the transition pipe, so that the heat generated by the heating rod and the exhaust gas can pass through the transition box and then enter the upper heat cover, effectively reducing the possibility of large particles in the exhaust gas entering the upper heat cover, and improving the efficiency and reliability of exhaust gas treatment. At the same time, the existence of the transition box also plays a buffering role, reducing the impact of the air supply fan and extending the service life of the equipment.

[0017] Preferably, a transition liquid is provided inside the transition box, the air supply duct penetrates into the transition box and a coil connected thereto is provided at the bottom, and the coil is provided with a plurality of air holes.

[0018] By adopting the above technical solution, the transition liquid can effectively absorb the heat in the air supply duct, reduce the gas temperature, and prevent the high-temperature gas from directly entering the upper heat shield, causing equipment damage or unstable operation. At the same time, the air permeability design on the coil allows the gas to be evenly dispersed, further improving the heat exchange efficiency and ensuring the stability and reliability of exhaust gas treatment. The transition liquid can also better adsorb multi-particles and absorb oil mist, perform exhaust gas treatment in the middle section, and reduce the exhaust gas treatment efficiency of the exhaust gas treatment module in the tail section.

[0019] Preferably, the air supply duct is connected to the coil by a flexible tube, a plurality of the air holes are opened downward, and a vibration spring is provided between the coil and the bottom wall of the transition box.

[0020] By adopting the above technical solution, the flexible pipe connection between the air supply duct and the coil can effectively absorb the vibration generated during the air supply process and ensure the stable operation of the system. The design of the air vent opening downward allows the bubbles to be fully dispersed during the rising process, increasing the contact area between the exhaust gas and the transition liquid, and improving the removal efficiency of harmful substances in the exhaust gas. The vibration spring between the coil and the bottom wall of the transition box can produce tiny vibrations under the impact of the air supply airflow, further promoting the uniform distribution of bubbles, enhancing the mixing effect of gas and liquid, and thus improving the exhaust gas purification capacity. In addition, the air vents can also be shaken during the vibration of the coil, so that particulate matter is not easy to accumulate at the air vents, or the accumulated dirt can be shaken to promote shedding and removal, so that the air vents remain unobstructed.

[0021] Preferably, the exhaust gas treatment module comprises a shell having an exhaust port, a plurality of activated carbon plates are arranged inside the shell, and a replacement port for the activated carbon plates to enter and exit is arranged on a side wall of the shell.

[0022] By adopting the above technical solutions, the exhaust gas treatment module can effectively adsorb and filter harmful substances in the exhaust gas generated during the vulcanization process, such as oil mist and particulate matter, thereby significantly reducing air pollution in the workshop. The design of the activated carbon plate makes the exhaust gas treatment module have a high adsorption efficiency, and it is easy to replace and maintain regularly, ensuring long-term stable operation.

[0023] Preferably, several of the activated carbon plates include a frame and a carbon plate body located inside the frame, the frame is provided with a flexible baffle, the frame and the flexible baffle jointly cover the replacement port, and the carbon plate body has a clearance hole for adjacent flexible baffles to fit and insert.

[0024] By adopting the above technical solution, the structural design of the activated carbon plate makes it more convenient and quick to replace the activated carbon plate. At the same time, the flexible baffle can effectively prevent exhaust gas leakage, ensuring the safety and effectiveness of the exhaust gas treatment process. Specifically, the design of the frame and the flexible baffle jointly covering the replacement port ensures that the exhaust gas will not leak during the replacement process, improving the safety of the operation. The design of the clearance hole on the carbon plate body allows adjacent flexible baffles to be adapted and inserted, further enhancing the sealing effect and ensuring the efficient operation of the exhaust gas treatment module.

[0025] Preferably, the exhaust port is connected to a straight exhaust pipe and a return pipe through a regulating valve, and the return pipe is connected to the lower heat cover.

[0026] By adopting the above technical solution, the recycling and efficient treatment of waste gas is realized. Specifically, by setting a regulating valve at the exhaust port and connecting the straight exhaust pipe and the return pipe, part of the waste gas can be re-introduced into the lower heat hood through the return pipe for further heating and treatment, reducing the direct emission of waste gas and improving energy utilization and environmental protection performance. At the same time, the existence of the straight exhaust pipe ensures that the system can quickly discharge the untreated waste gas when necessary, ensuring the stability and safety of the system.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The heat and exhaust gas from the heating rod are pumped into the upper heat cover by the air supply fan, and the exhaust gas is discharged from the box and sent to the exhaust gas treatment module by the air outlet fan, so that the box is maintained in a negative pressure state, effectively preventing the exhaust gas from leaking from the inlet and outlet of the vulcanization module, and significantly improving the air quality of the workshop;

[0029] 2. The activated carbon plate installed in the exhaust gas treatment module can efficiently absorb oil mist and particulate matter in the exhaust gas, further purify the exhaust gas, reduce environmental pollution, and protect the health of operators;

[0030] 3. The transition box and coil structure set in the box body, through the design of transition liquid and air holes, help to stabilize the flow of exhaust gas, improve the efficiency of exhaust gas treatment, while reducing system vibration and extending the service life of the equipment.

[0048] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can completely combine the embodiments of the present invention to obtain other embodiments without creative work, and these embodiments are also within the scope of protection of the present invention.

[0049] The inventor of the present application found that the production process of the cold shrink tube in the related art is usually to first mix the raw materials in a specific proportion, then extrude them through an extruder with a mold, and then transport them to the vulcanization module for vulcanization, and finally cool and collect the materials. However, the process of vulcanization is often accompanied by a certain amount of waste gas output, and the waste gas contains a certain amount of oil mist and particulate matter. If the waste gas leaks from the feed or discharge port of the vulcanization module, it will affect the air quality in the workshop to a certain extent, so it needs to be improved. To this end, the present application mainly adopts the following electric cold shrink tube production device, including a mixing module, an extrusion module, a vulcanization module and a cooling module. The vulcanization module includes a box body, a heating rod is arranged inside the box body, and a lower heat cover is arranged below the heating rod. The lower heat cover is connected to an air supply fan and an air supply duct. An upper heat cover is arranged above the heating rod, and the upper heat cover is connected to the air supply duct. The upper heat cover is connected to an air outlet fan and an air outlet duct, and the air outlet duct extends out of the box body and is connected to an exhaust gas treatment module. The heat and exhaust gas at the heating rod are pumped into the upper heat hood along the air supply duct through the air supply fan, and the exhaust gas in the upper heat hood finally flows out of the box along the air outlet duct under the action of the air outlet fan and enters the exhaust gas treatment module, and is discharged after being treated by the exhaust gas treatment module. During this process, the box is continuously in a negative pressure state, so that the air flow direction at the inlet / outlet of the box for the cold shrink tube to enter / exit is from outside to inside, and therefore the exhaust gas is not easy to leak from the inlet / outlet of the box, thereby achieving the effect of reducing the leakage of exhaust gas during the vulcanization process. The present application is further described in detail below.

[0050] Example

[0051] Reference Figure 1 The electric cold shrink tube production device provided in the embodiment of the present application includes a mixing module 1, an extrusion module 2, a vulcanization module 3 and a cooling module 4 which are arranged in sequence.

[0052] Reference Figure 1 and Figure 2 The mixing module 1 cooperates with the extrusion module 2 to achieve the mixing and extrusion of the raw materials. The outlet of the extrusion module 2 is equipped with a mold 21, which is used to limit the shape and size of the discharged material. In this embodiment, a double mold 21 is used for discharging, thereby realizing a "one out of two" mode of two discharging production lines of one extrusion module 2. The mold 21 itself is connected to the extrusion module 2 in a detachable manner, so that the number or specifications of the mold 21 can be adjusted according to actual conditions;

[0053] Reference Figure 1 The main function of the vulcanization module 3 is to heat the material strip to achieve vulcanization of the material strip.

[0054] Reference Figure 1 The cooling module 4 is located downstream of the vulcanization module 3 to cool the material strip after high-temperature vulcanization.

[0055] Reference Figure 3 and Figure 4 The vulcanization module 3 includes a box body 31, and the box body 31 has an inlet / outlet for the material belt to enter / exit. A heating rod 32 is arranged inside the box body 31, and the heating rod 32 is composed of a plurality of electric heating elements. The electric heating element can be a resistance wire or a carbon fiber heating element. Both materials have good thermal conductivity and a long service life. The two ends of the heating rod 32 are rotatably arranged on the two opposite inner walls of the box body 31, and the heating temperature can be controlled by adjusting the voltage. The surface of the heating rod 32 can be coated with a layer of high-temperature resistant paint to prevent oxidation and corrosion. A temperature control sensor can also be arranged inside the box body 31 to monitor the temperature inside the box body 31 in real time, and automatically adjust the power of the heating rod 32 through the controller to maintain a constant vulcanization temperature.

[0056] A lower heat cover 5 is provided below the heating rod 32. The lower heat cover 5 is funnel-shaped and connected to an air supply fan 51 and an air supply duct 52 at the bottom. The lower heat cover 5 can be made of high-temperature resistant ceramic fiber material to reduce heat loss. The air supply fan 51 can be a centrifugal fan, which is characterized by large air volume, low noise, and suitable for long-term operation. The air supply fan 51 is used to pump the heat and exhaust gas at the lower heat cover 5 to the air supply duct 52. The air supply duct 52 is made of high-temperature resistant stainless steel material to ensure that it will not be deformed or damaged in a high temperature environment.

[0057] An upper heat cover 6 is arranged above the heating rod 32, and the upper heat cover 6 can also be made of high temperature resistant ceramic fiber material. The upper heat cover 6 is connected to the air supply duct 52, and the upper heat cover 6 is in an inverted funnel shape and is connected to an air outlet fan 61 and an air outlet duct 62 at the top. The air outlet fan 61 is also a centrifugal fan, and its air volume and pressure can be adjusted according to actual conditions. The air outlet duct 62 is also made of high temperature resistant stainless steel material to ensure that it works normally in a high temperature environment.

[0058] The air outlet duct 62 extends out of the box body 31 and is connected to the exhaust gas treatment module 7. The heat and exhaust gas at the heating rod 32 are pumped into the upper heat cover 6 along the air supply duct 52 through the air supply fan 51, and the exhaust gas in the upper heat cover 6 eventually flows out of the box body 31 along the air outlet duct 62 under the action of the air outlet fan 61 and enters the exhaust gas treatment module 7, and is discharged after being treated by the exhaust gas treatment module 7. During this process, the box body 31 is continuously in a negative pressure state, so that the air flow direction at the inlet / outlet of the box body 31 is from outside to inside, and therefore the exhaust gas is not easy to leak from the inlet / outlet of the box body 31.

[0059] Reference Figure 4 and Figure 5 The upper heat shield 6 includes a pair of movable shields 63 and a plurality of guide plates 64 are arranged inside. The guide plates 64 can be made of high-temperature resistant stainless steel material, and a layer of anti-oxidation coating can be coated on its surface to extend its service life. The plurality of guide plates 64 are divided into two groups and the two groups of guide plates 64 are respectively connected to the inner wall of the corresponding movable shield 63. The two groups of guide plates 64 are staggered so that the flow path of the airflow in the upper heat shield 6 is "S" shaped. The side wall of the box body 31 is provided with an adjustment drive 65 for driving one of the movable shields 63 to move to adjust the staggered degree of the guide plates 64, and the other movable shield body 63 is fixed between the box body 31. The adjustment drive 65 can adopt an electric cylinder or a hydraulic cylinder, and the telescopic length of the electric cylinder or the hydraulic cylinder is adjusted by the controller to change the staggered degree between the plurality of guide plates 64. The advantage of this design is that the layout of the guide plates 64 can be flexibly adjusted according to different production conditions, so as to adapt to different production needs.

[0060] The bottom of several guide plates 64 is provided with anti-scratch treatment, and guide rollers can be rotated at the bottom or rounded at the bottom. The design of guide rollers or guide rounded corners can reduce the probability of wear of the shrink tube during transmission and improve the stability during transmission. In the actual processing process, the strip of the shrink tube will shake under the action of the airflow on both sides, which may collide with the guide plate 64. The guide rollers or guide rounded corners can reduce the wear of the strip caused by the collision. And the design of guide rollers or guide rounded corners can also make the upper heat cover 6 and the lower heat cover 5 closer when the position is laid out, which helps the exhaust gas flow in the upper heat cover 6 and the lower heat cover 5 without leakage. The guide roller can be made of wear-resistant and heat-resistant plastic or metal material, and its surface is smooth to reduce friction. The diameter and spacing of the guide rollers can be adjusted according to the size of the shrink tube to ensure the smooth transmission of the shrink tube.

[0061] Reference Figure 4 and Figure 6 A transition box 8 is also provided inside the box body 31. The transition box 8 is connected between the air supply duct 52 and the upper heat shield 6 for mid-section treatment of the exhaust gas. The end of the air supply duct 52 extends deep into the transition box 8, and the top of the transition box 8 is connected to the upper heat shield 6 through a transition pipe 81. There is a transition liquid inside the transition box 8. The transition liquid can be water or other non-toxic and harmless liquids. Its function is to absorb harmful substances in the exhaust gas and reduce the toxicity of the exhaust gas. For example, particulate matter in the exhaust gas can settle in the liquid with bubbles, or the oil mist in the exhaust gas can be absorbed or diluted in the lipophilic liquid. The bottom of the air supply duct 52 extends deep into the transition liquid and is connected to a coil 83 through a flexible tube 82.

[0062] Reference Figure 7 The coil 83 is provided with a plurality of air holes 84, and the openings of the plurality of air holes 84 are all arranged downward. When the coil 83 is in the ventilation state, the gas ejects downward from the plurality of air holes 84 to form bubbles that impact the bottom wall of the transition box 8, and floats up after the impact to disturb the coil 83 itself, thereby increasing the instability during the ventilation process. A vibration spring 85 is provided between the coil 83 and the inner bottom wall of the transition box 8. The design of the vibration spring 85 can further expand the instability of the coil 83, and during the vibration process of the coil 83, it can also prevent the air holes 84 of the coil 83 from being blocked due to long-term operation, thereby ensuring smooth air flow.

[0063] Reference Figure 6 and Figure 8The exhaust gas treatment module 7 includes a shell 71, and the shell 71 is located at the top of the box body 31. The bottom of the shell body 71 is connected to the air outlet duct 62, the top cover of the shell body 71 is detachable and has an exhaust port 72, and the exhaust port 72 is connected to a straight pipe 74 and a return pipe 75 through a regulating valve 73. The return pipe 75 is connected to the coil 83 in the transition box 8 and a check valve is provided at the connection. The design of the return pipe 75 can selectively re-introduce part of the exhaust gas into the transition box 8 for secondary treatment, thereby improving the exhaust gas treatment effect. On the other hand, the regulating valve 73 can adjust the exhaust gas emission and reflux according to actual needs. By adjusting the actual emission, the overall negative pressure inside the box body 31 can also be controlled. The higher the negative pressure inside the box body 31, the lower the probability of exhaust gas leakage at the inlet / outlet of the box body 31.

[0064] Several activated carbon plates 76 are stacked from top to bottom inside the shell 71, and a replacement port 77 for the activated carbon plates 76 to enter and exit is provided at the bottom of the side wall of the shell 71. The activated carbon plate 76 includes a frame 761 and a carbon plate body 762 located inside the frame 761. The carbon plate body 762 can be made of high-efficiency adsorption materials, such as coconut shell activated carbon or coal-based activated carbon, which have high specific surface area and adsorption capacity. The frame 761 can be made of aluminum alloy material, which is light and durable. A flexible baffle 78 is fixedly provided on the top of the side of the frame 761 close to the replacement port 77. The flexible baffle 78 can be made of heat-resistant silicone or rubber material and has good sealing performance. The thickness of the frame 761 and the width of the flexible baffle 78 can jointly cover the replacement port 77, that is, the replacement port 77 cannot be covered by the thickness of the frame 761 alone. The bottom of the frame 761 near the replacement port 77 has a clearance hole 780 for the adjacent flexible baffle 78 to fit in and insert, so as to achieve stable stacking of several activated carbon plates 76. When the adsorption capacity of the activated carbon plate 76 at the bottom layer decreases, the activated carbon plate 76 at the bottom layer can be pulled out, and the several activated carbon plates 76 above will descend in an orderly manner, and the replacement port 77 will be re-sealed, and then a new activated carbon plate 76 can be added at the top, thereby improving the comprehensive utilization rate of several activated carbon plates 76.

[0065] The implementation principle of this embodiment is:

[0066] By rationally designing the structure of the vulcanization module 3, the air supply fan 51 is used in conjunction with the air outlet fan 61 to form a negative pressure environment inside the box 31, which effectively reduces the leakage of exhaust gas. At the same time, the use of the exhaust gas treatment module 7 ensures that the exhaust gas is effectively treated before being discharged, thereby improving the air quality of the workshop. In addition, by optimizing the design of the heating rod 32 and the application of the temperature control system, the uniformity of the vulcanization process and the product quality are guaranteed. By arranging the guide plate 64 inside the upper heat cover 6 and adopting an adjustable design, the distribution of the airflow in the upper heat cover 6 is more uniform, thereby improving the exhaust gas treatment efficiency. By adjusting the degree of staggering of the guide plate 64, it can adapt to different production needs, thereby enhancing the flexibility and applicability of the device. By arranging the guide roller 66 at the bottom of the guide plate 64, the friction of the shrink tube during the transmission process is reduced, thereby improving the stability of the transmission process. At the same time, by arranging the transition box 8 and the coil 83, it is achieved that the middle section can effectively absorb harmful substances in the exhaust gas, thereby reducing the "toxicity" of the exhaust gas and improving the environmental protection performance. By setting up an efficient activated carbon plate 76 and a reasonable waste gas treatment process, it is ensured that the waste gas is effectively treated before being discharged, thereby improving environmental protection performance. At the same time, through the design of the return pipe 75, secondary treatment of the waste gas is achieved, further improving the waste gas treatment effect, and the negative pressure level inside the entire box 31 can be adjusted synchronously.

[0067] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
