Technical Field
[0001] This utility model relates to the field of cable protection pipe production technology, specifically to an extrusion molding heat dissipation device for the production of MPP cable protection pipes. Background Technology
[0002] In the production process of MPP cable protection pipes, extrusion molding is a commonly used processing technology. During the extrusion molding process of cable protection pipe production, plastic raw materials are melted and extruded into a tube shape by the screw rotation of the extruder and the action of the heating device. However, the temperature of the freshly extruded MPP cable protection pipe is high, and it is necessary to dissipate heat in time. If it is not treated, it will affect the product quality of the MPP cable protection pipe, which will easily lead to pipe deformation, thereby affecting the appearance and performance of the pipe and reducing the product qualification rate. In addition, the high temperature will also prolong the cooling time of the pipe, thereby reducing the production efficiency of cable protection pipes.
[0003] Traditional heat dissipation methods typically employ natural air cooling or water cooling, which have limitations. Natural air cooling is slow and cannot meet the needs of large-scale production, while water cooling, although effective, may suffer from uneven cooling of pipes and water waste. Therefore, to improve the production quality and efficiency of MMP cable protection pipes, it is necessary to develop an efficient and reliable extrusion molding heat dissipation device to enhance production efficiency and reduce production costs and water waste. Utility Model Content
[0004] The purpose of this invention is to provide an extrusion molding heat dissipation device for the production of MPP cable protection pipes, so as to solve the problems of slow heat dissipation and water waste during the production of cable protection pipes mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an extrusion molding heat dissipation device for the production of MPP cable protection pipes, comprising a housing, a water storage tank fixedly installed on the outer surface of the housing, a drain pump fixedly installed on the side surface of the water storage tank, one end of the drain pump penetrating the outer surface of the housing, a water pump fixedly installed on the outer surface of the housing, one end of the water pump being in contact with the side surface of the water storage tank, one end of the water pump penetrating the outer surface of the housing, a spray pipe fixedly installed inside the housing, the spray pipe having a C-shaped design and being connected to the drain pump, and through holes on both sides of the housing.
[0006] Preferably, a fixing frame is fixedly installed inside the housing, and the fixing frame is designed to be high on both sides and low in the middle. An electric guide roller is fixedly installed on the outer surface of the fixing frame, and the electric guide roller is designed to be inclined V-shaped, and the outer surface of the electric guide roller is in contact with the outer surface of the MPP cable protection pipe.
[0007] By adopting the above technical solution, the design of the electric guide roller allows the MPP cable protection pipe to move inside the housing, and the V-shaped design of the electric guide roller allows MPP cable protection pipes of different sizes to be supported and moved for transportation.
[0008] Preferably, brushes are fixedly attached to the outer surfaces of both sides of the housing, and the height of the center of the brushes is the same as the height of the electric guide roller, and the outer surface of the brushes is in contact with the outer surface of the MPP cable protection pipe.
[0009] By adopting the above technical solution, the MPP cable protection tube that extends into the shell can be blocked by a brush, so that the gap between the MPP cable protection tube and the shell can be filled by the brush. This prevents the water mist sprayed when cooling the MPP cable protection tube from leaking out, thus reducing the waste and loss of water resources.
[0010] Preferably, the water storage tank is equipped with a cooling element inside, and a semiconductor heat exchange plate is fixedly installed on one outer surface of the cooling element. The outer surface of the semiconductor heat exchange plate is in contact with the outer surface of the cooling element. A cooling fan heat exchange plate is fixedly installed at one end of the semiconductor heat exchange plate outside the water storage tank, and a heat utilization mechanism is provided between the cooling fan heat exchange plate and the shell. A temperature detection probe is threadedly installed on the outer surface of the water storage tank, and the temperature detection probe does not contact the outer surface of the cooling element.
[0011] By adopting the above technical solution, the design of the semiconductor heat exchanger can cool the cooling element, thereby cooling the water stored in the water tank and preventing the water temperature inside the water tank from becoming too high, which would reduce the cooling efficiency of the MPP cable protection pipe.
[0012] Preferably, the heat utilization mechanism includes: an air supply pipe, which is fixedly installed on one outer surface of the heat exchange fins of the cooling fan; a jet ring is fixedly installed on the outer surface of the housing near the drain pump, and the outer surface of the jet ring is evenly provided with air outlet holes; the jet ring and the brush are concentrically designed; and the jet ring is connected to the air supply pipe.
[0013] Using the above technical solution, when the semiconductor heat exchanger is running, it will conduct heat to the heat exchanger of the cooling fan and dissipate it. The heat exchanger of the cooling fan can carry away the heat and discharge it to the outside through the air duct. The hot air can be sprayed out evenly through the air jet ring, and the sprayed hot air will dry and remove the moisture on the outer surface of the MPP cable protection pipe.
[0014] Preferably, the interior of the housing is inclined, and a water inlet pipe is provided on one outer surface of the housing. A filter screen frame is slidably installed on the side surface of the housing, and the filter screen frame is inclined. One end of the water pump is connected to the housing, and the other end of the water pump is connected to the water storage tank.
[0015] By adopting the above technical solution, the inclined design inside the shell allows the water that falls after cooling to be concentrated and collected. At the same time, the filter screen can filter the debris washed down, and the inclined design of the filter screen can also collect the debris, preventing the debris washed down from circulating in the water cooling system and causing blockage. In addition, the debris collected by the filter screen can be easily removed.
[0016] Preferably, a storage bin is slidably mounted on the outer surface of the housing away from the drainage pump, and the outer surface of the storage bin is in contact with the outer surface of the housing. The storage bin is located below the brush. Observation windows are fixedly mounted on the outer surfaces of both sides of the housing, and the observation windows are connected to the housing by screws.
[0017] By adopting the above technical solution, the design of the storage box allows for cleaning of the side of the MPP cable protection pipe that enters the housing. The brush can remove debris from the outer surface of the MPP cable protection pipe, thus cleaning the debris on the outer surface in advance, reducing the amount of debris entering the housing, facilitating the cleaning and collection of debris, and reducing the difficulty of subsequent handling of debris entering the housing.
[0018] Compared with the prior art, the beneficial effects of this utility model are: the extrusion molding heat dissipation device for the production of MPP cable protection pipes:
[0019] 1. The water stored in the water tank can be pumped out by the drain pump, so that the water inside the water tank can be pumped into the spray pipe. Through the C-shaped design of the spray pipe, the sprayed water mist can be evenly sprayed onto the MPP cable protection pipe that enters the shell, ensuring that the MPP cable protection pipe is in contact with the cooling water from all directions without dead angles. Compared with the traditional cooling method, the atomized cooling method can significantly improve the heat dissipation efficiency, improve production efficiency and yield.
[0020] 2. The use of semiconductor heat exchangers can reduce the temperature of the cooling element, thereby lowering the temperature of the water inside the storage tank. Combined with the water pump, the used cooling water can be drawn back into the storage tank, facilitating the circulation and reuse of the cooling water, reducing waste, and controlling the temperature of the cooling water inside the storage tank to prevent it from becoming too high and reducing the cooling efficiency of the MPP cable protection pipe. The cooling water can also be circulated for reuse.
[0021] 3. The brush can effectively block the water mist sprayed from the spray pipe inside the housing, reducing the loss of cooling water. It can also clean the debris and dust remaining on the outer surface of the MPP cable protection pipe, preventing dust and debris from entering the housing and causing filter pressure on the filter screen. This reduces the potential danger of slipping on the ground caused by the water mist exiting the device, and can also pre-clean the MPP cable protection pipe.
[0022] 4. The brush can clean the debris and dust on the outer surface of the MPP cable protection pipe and collect it through the storage bin. The filter screen design can filter and collect the dust and impurities on the outer surface of the MPP cable protection pipe, so that the debris will not circulate in the cooling system and cause blockage. The dust and impurities stored in the filter screen and storage bin can be easily pulled out for cleaning and maintenance. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figure 1-6 This utility model provides a technical solution: an extrusion molding heat dissipation device for the production of MPP cable protection pipes, including a housing 1, a water storage tank 2 fixedly installed on the outer surface of the housing 1, and a drain pump 3 fixedly installed on the side surface of the water storage tank 2, with one end of the drain pump 3 penetrating through the outer surface of the housing 1. A water pump 15 is fixedly installed on the outer surface of the housing 1, with one end of the water pump 15 in contact with the side surface of the water storage tank 2 and one end of the water pump 15 penetrating through the outer surface of the housing 1. A spray pipe 4 is fixedly installed inside the housing 1, and the spray pipe 4 has a C-shaped design and is connected to the drain pump 3.
[0032] When the drainage pump 3 is started, the water in the water storage tank 2 is extracted and precisely delivered to the interior of the spray pipe 4. The unique C-shaped structure design of the spray pipe 4 allows water mist to be sprayed out and evenly covered on the outer surface of the MPP cable protection pipe, ensuring that the MPP cable protection pipe is in full-range, no-dead-angle contact with the cooling water. Compared with traditional cooling methods, atomization cooling significantly increases the contact area between the MPP cable protection pipe and the cooling water, accelerates heat exchange efficiency, and greatly shortens the cooling time of the pipe. It can dissipate heat in a timely and efficient manner, which can not only effectively avoid quality problems such as pipe deformation and cracking caused by high temperature, but also reduce production losses and provide a strong guarantee for improving product yield and production efficiency.
[0033] A fixing frame 10 is fixedly installed inside the housing 1. The fixing frame 10 is designed to be high on both sides and low in the middle. An electric guide roller 11 is fixedly installed on the outer surface of the fixing frame 10. The electric guide roller 11 is designed to be inclined in a V shape. The outer surface of the electric guide roller 11 is in contact with the outer surface of the MPP cable protection pipe.
[0034] The electric guide roller 11 provides stable power for the transmission of MPP cable protection pipes within the housing 1, and can be easily removed from the fixed frame 10 for replacement. The electric guide roller 11 ensures the continuity of the production process by enabling the uniform movement of the MPP cable protection pipes. The electric guide roller 11 adopts a unique V-shaped design, which breaks through the size limitations of traditional guide rollers and can stably support MPP cable protection pipes of different outer diameters. When cooling MPP cable protection pipes, whether it is a small-diameter pipe or a large-size pipe, the V-shaped guide roller can closely fit the pipe wall, preventing the pipe from shifting or slipping, while ensuring the stability of the MPP cable protection pipes during the conveying process. This can effectively improve the equipment's compatibility with multiple specifications of MPP cable protection pipes and increase production efficiency.
[0035] Brushes 12 are fixedly attached to the outer surfaces of both sides of the housing 1, and the height of the center of the brushes 12 is the same as the height of the electric guide roller 11. The outer surface of the brushes 12 is in contact with the outer surface of the MPP cable protection pipe.
[0036] After the MPP cable protection pipe enters the housing 1, the brush 12 can form a flexible sealing barrier. When the MPP cable protection pipe passes through the housing 1, the densely arranged brush 12 fits tightly against the pipe wall and adaptively fills the gap between the MPP cable protection pipe and the housing 1. This design effectively blocks the path of cooling water mist overflow, ensuring that the cooling water sprayed from the spray pipe 4 can fully act on the pipe surface, avoiding water resource loss caused by water mist diffusion. Moreover, through this physical sealing method, the utilization rate of the cooling medium is improved, and the risk of slippery workshop floor is reduced, achieving the dual optimization of environmental protection, energy saving and safe production.
[0037] The water storage tank 2 is equipped with a cooling element 5, and a semiconductor heat exchange plate 6 is fixedly installed on one side of the outer surface of the cooling element 5. The outer surface of the semiconductor heat exchange plate 6 is in contact with the outer surface of the cooling element 5. A cooling fan heat exchange plate 7 is fixedly installed at one end of the semiconductor heat exchange plate 6 outside the water storage tank 2. A heat utilization mechanism is provided between the cooling fan heat exchange plate 7 and the shell 1. A temperature detection probe 16 is threadedly installed on the outer surface of the water storage tank 2, and the temperature detection probe 16 does not contact the outer surface of the cooling element 5.
[0038] When the equipment is running, the semiconductor heat exchanger 6 will quickly activate, rapidly dissipating and transferring the heat from the cooler 5, allowing the temperature of the cooling water in the water tank 2 to continuously decrease. The temperature inside the water tank 2 can be monitored in real time by the temperature detection probe 16. As the core cooling unit, the cooler 5 is tightly integrated with the water tank 2, continuously absorbing heat from the water in the water tank 2. Through heat conduction and heat exchange, the water temperature in the water tank 2 is effectively controlled, ensuring that the water temperature in the water tank 2 is always kept within a suitable range. This design effectively avoids the problem of cooling efficiency reduction caused by rising water temperature, ensuring a constant supply of low-temperature, high-efficiency cooling medium during the cooling process of the MPP cable protection pipe, providing a stable guarantee for improving the heat dissipation effect of the pipe and production quality.
[0039] The heat utilization mechanism includes: an air supply pipe 8, which is fixedly installed on one side of the outer surface of the heat exchange fins 7 of the cooling fan; a jet ring 9 is fixedly installed on the outer surface of the housing 1 near the drain pump 3, and the outer surface of the jet ring 9 is evenly provided with air outlet holes; the jet ring 9 and the brush 12 are concentrically designed; and the jet ring 9 is connected to the air supply pipe 8.
[0040] When the semiconductor heat exchanger 6 starts running, based on the unique thermoelectric effect, it will quickly conduct the generated heat to the cooling fan heat exchanger 7 while realizing the cooling function. The cooling fan heat exchanger 7, with its efficient heat conduction performance and large-area heat dissipation fin structure, quickly absorbs and dissipates the heat.
[0041] At this time, the cooling fan matching the heat exchanger 7 operates synchronously, driving the airflow through the air duct 8 to form a directional air channel and orderly dissipating the heat. The hot airflow eventually converges to the jet ring 9 and is sprayed onto the MPP cable protection pipe, so that the hot air is sprayed outward with a uniform and stable pressure distribution. This hot air can be blown evenly onto the outer surface of the MPP cable protection pipe, and the residual moisture on the outer surface of the MPP cable protection pipe is quickly evaporated through thermal convection. This not only achieves efficient drying of the surface of the MPP cable protection pipe, but also avoids quality problems such as surface water stains and oxidation that may be caused by residual moisture, providing clean and dry pipe surface conditions for subsequent processes.
[0042] The interior of the housing 1 is designed to be inclined, and a water inlet pipe is provided on one side of the outer surface of the housing 1. A filter screen frame 14 is slidably installed on the side surface of the housing 1, and the filter screen frame 14 is designed to be inclined. One end of the water pump 15 is connected to the housing 1, and the other end of the water pump 15 is connected to the water storage tank 2.
[0043] The inclined design inside the housing 1 creates a natural flow-guiding slope, ensuring that the water dripping from the MPP cable protection pipe after cooling can converge into the interior of the housing 1 under gravity. The water is then pumped and collected by the water pump 15, achieving efficient water collection and recycling. Meanwhile, the built-in filter frame 14 plays a crucial role in accurately intercepting debris and impurities washed off the surface of the MPP cable protection pipe. The inclined layout of the filter frame 14 allows the intercepted debris to slide downwards along the slope, preventing it from circulating in the water cooling system and eliminating potential problems such as pipe blockage and nozzle clogging. In addition, this design greatly improves maintenance convenience. Staff can easily remove the filter frame 14 with simple operations to quickly remove accumulated debris and ensure the continuous and stable operation of the equipment.
[0044] A storage box 13 is slidably installed on the outer surface of the housing 1 away from the drain pump 3, and the outer surface of the storage box 13 is in contact with the outer surface of the housing 1. The storage box 13 is located below the brush 12. Observation windows 17 are fixedly installed on the outer surfaces of both sides of the housing 1, and the observation windows 17 are connected to the housing 1 by screws.
[0045] The design of the storage box 13 provides an effective solution for the pre-treatment of MPP cable protection pipes. Before the pipe enters the housing 1, the brush 12 on the side surface of the housing 1 will actively pre-clean the outer surface of the MPP cable protection pipe. The brush 12 removes debris, dust and other impurities attached to the surface of the MPP cable protection pipe, forming the first protective barrier. At the same time, the condition of the MPP cable protection pipe entering the housing 1 can be observed in real time through the observation window 17.
[0046] This pre-cleaning mechanism significantly reduces the chance of debris entering the housing 1, which not only reduces the interception pressure on the subsequent filter screen 14, but also allows the cleaned debris to fall directly into the storage bin 13. This allows staff to complete the cleaning work simply by periodically emptying the storage bin 13, greatly simplifying the maintenance process and effectively improving the cleanliness and operational stability of the production system.
[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
