Description

Technical Field

[0001] The utility model relates to the technical field of pipe production, and more specifically, to a cooling device for pipe production. Background Art

[0002] In the production of existing plastic pipes, the granular mixed materials are heated to a molten state and then extruded through an extruder. The temperature of the formed pipe is high, and the pipe needs to be cooled down as necessary. The cooling method of existing pipe production mostly adopts spraying. The spray head in the water tank is mostly fixed, and the position of the sprayed water cannot be specified. There are cases where some pipe surfaces cannot be sprayed, and the cooling requirements of high-temperature pipes cannot be met, resulting in deformation of the pipe due to uneven cooling, thereby affecting the appearance and product quality of the pipe. At the same time, the water sprayed from the spray head directly impacts the surface of the pipe, which will also cause the surface of the pipe to deform. In the prior art, some pipe cooling equipment uses atomizing nozzles to cool the pipe, which can improve the uniformity of pipe cooling to a certain extent through water mist, but the flow effect of water mist of this type of cooling equipment is poor, and uneven cooling of the pipe will still occur. Especially when switching to large-diameter pipes, the disadvantages of poor water mist flow effect will be further revealed, and the uneven cooling of the pipe will be more serious. Utility Model Content

[0003] In order to overcome the defects that the atomizing nozzles used in the pipe cooling equipment in the above-mentioned prior art have limited cooling effect on the pipe and cannot meet the cooling needs of pipes of various specifications, the utility model provides a cooling device for pipe production, so that the mist can fully cover the surface of the pipe to ensure the cooling effect of the pipe.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a cooling device for pipe production, including a box for storing cooling water, an inlet and an outlet respectively arranged at both ends of the box, and a water inlet pipe connected to the box, and also including a fogger and a fan respectively connected to the box, the fogger is used to generate mist in the box to cool the pipe, and the fan is used to increase the fluidity of the mist in the box.

[0005] When the utility model is working, cooling water is first injected into the box through the water inlet pipe, and the pipe to be cooled enters the box through the feed port. The fogger in the box uses cooling water to generate fog, and the fan blows the fog to increase the floating effect of the fog and the fluidity of the fog, so that the fog fills the inside of the box, and then the fog is evenly distributed on the surface of the pipe, achieving a uniform and rapid cooling effect. After cooling, the pipe moves out through the discharge port. Further, a plurality of foggers are arranged in the box to ensure the concentration of fog and the cooling effect. At the same time, the foggers are evenly distributed in the box, and a high-power ultrasonic fogger is used; further, the box is connected to a plurality of fans, so as to fully stir the air in the box to ensure that the fog fills the internal space of the box; further, the fan is a waterproof fan, and the air inlet of the fan is connected to an air filter, and the dust or impurities in the air are filtered out by the air filter to avoid the contamination of the cooling water.

[0006] Preferably, a mounting hole is provided at the bottom of the box, the fogger is mounted on the mounting hole and the wires of the fogger are located outside the box.

[0007] The fogger is installed at the bottom of the water tank through the mounting hole. When in use, the cooling water in the water tank covers the fogger. At the same time, the wires connected to the fogger are arranged outside the box. The existing fogger is generally directly immersed in the water, and some of the wires connected to it are also immersed in the water. The cooling water of this device needs to cool the pipe. During the cooling process, the temperature of the cooling water itself will rise. At this time, if the wires are immersed in water, the wires will accelerate aging under the immersion of warm water, and there is a risk of leakage when used for a long time. This problem can be avoided by setting the wires outside the box.

[0008] Preferably, a sealing ring is provided between the fogger and the mounting hole.

[0009] In order to prevent cooling water from leaking from the mounting hole, a sealing ring is provided between the fogger and the mounting hole to increase the sealing between the fogger and the box. At the same time, during actual use, on the premise of ensuring that the fogger is installed firmly, sealant will be applied to the mounting hole to fully prevent water leakage from the box.

[0010] Preferably, it also includes a valve installed on the water inlet pipe and a first water level sensor installed on the box body, the first water level sensor is connected to the valve signal, and the first water level sensor is used to detect the lowest water level in the box body.

[0011] The first water level sensor is set to detect the lowest water level of cooling water. When the cooling water level is lower than the set value, the valve opens automatically, and the cooling water enters the box through the water inlet pipe to prevent the mist generator from being unable to mist due to the water level being too low, to prevent production hazards caused by human error in not replenishing cooling water to the box in time, and to avoid unnecessary losses.

[0012] Preferably, it further comprises a second water level sensor installed on the box body, a drain pipe connected to the box body, and a pump body connected to the drain pipe, wherein the second water level sensor is used to detect the highest water level in the box body.

[0013] The second water level sensor is set to detect the highest water level of the cooling water. When the cooling water level is higher than the set value, the valve will automatically close if it is not closed. At the same time, the pump body will start to discharge the excess cooling water through the drain pipe to avoid the water level being too high.

[0014] Preferably, it also includes a temperature sensor installed in the box, and the temperature sensor is connected to the valve and the pump body signal.

[0015] After the mist generated by the fogger cools the pipe, it is directly evaporated or adheres to the surface of the pipe to form a water film and then drips into the box. After a long period of cooling, the cooling water in the box will gradually heat up. To avoid the cooling water temperature being too high, a temperature sensor is installed in the box. At the same time, the temperature sensor is connected to the pump body and valve signal. When the temperature sensor detects that the temperature in the box is too high, the valve and the pump body are opened at the same time, the pump body discharges the high-temperature cooling water, and the valve opens the water inlet pipe to inject cooling water with a lower temperature, thereby lowering the temperature of the cooling water in the box to ensure the normal cooling work.

[0016] Preferably, it also includes pipe diameter adapter rings respectively installed on the feed inlet and the feed outlet, and the pipe diameter adapter rings and the feed inlet and the feed outlet are detachable structures.

[0017] This device uses a fogger in conjunction with a fan to cool the pipe, and is applicable to pipes of different diameters. Therefore, detachable pipe diameter adapter rings are respectively installed at the inlet and outlet of the box. When pipes of different diameters need to be cooled, pipe diameter adapter rings with corresponding opening sizes can be replaced, thereby meeting the support and guiding requirements of pipes of different diameters, so that this device can meet the cooling work of pipes of various sizes.

[0018] Preferably, the pipe diameter adapter ring is made of elastic material and the inner side is used to fit with the outer surface of the pipe.

[0019] The pipe diameter adapter ring is set to an elastic material and fits the pipe. When the pipe moves, the pipe diameter adapter ring scrapes away the water on the surface of the pipe to prevent excessive moisture from being carried out of the box by the surface of the pipe. Specifically, the pipe diameter adapter ring can be made of rubber or silicone.

[0020] Preferably, the center of the opening of the pipe diameter adaptation ring is not higher than the center of the inlet or the outlet in the vertical direction.

[0021] The diameters of the inlet and outlet of the box are fixed. When the diameter of the pipe is large, the opening of the pipe adapter ring is concentric with the inlet or outlet. Since the pipe adapter ring itself is made of elastic material, it will produce elastic deformation. Therefore, when the diameter of the pipe is small, the center of the opening of the pipe adapter ring is set directly below the center of the inlet or outlet, thereby reducing the area of ​​the elastic material below the opening of the pipe adapter ring, reducing the elastic deformation of the pipe adapter ring, ensuring the support of the pipe by the pipe adapter ring, and ensuring that the opening of the pipe adapter ring can always fit the surface of the pipe, ensuring the wiper effect on the pipe.

[0022] Preferably, it further comprises a sewage pipe arranged at the bottom of the box body, and the end of the sewage pipe is connected with a plug.

[0023] During the long-term use of this device, impurities are inevitably present in the cooling water. A drain pipe is provided to discharge the cooling water and impurities together to avoid excessive impurities in the water affecting the cooling work. At the same time, the plug can also be set as a valve, and the drainage effects of the two are similar. Furthermore, a window is provided on the box body, and the window is made of transparent material to facilitate observation of the cooling water.

[0024] Compared with the prior art, the utility model has the following beneficial effects:

[0025] A fogger is set up to produce mist using cooling water, and then the fan is used to blow the mist so that the mist fills the entire box, so that the mist can fully contact the surface of the pipe, and the pipe is fully and evenly cooled to avoid deformation of the pipe due to uneven cooling, thereby ensuring the overall roundness of the pipe. At the same time, under the uniform cooling effect of the mist, the performance indicators such as tensile yield stress, impact strength and elongation at break of the pipe are also better, thereby improving the production quality of the pipe.

[0033] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0034] Example 1

[0035] like Figure 1-2 As shown, a cooling device for pipe production includes a box 1 for storing cooling water, an inlet 2 and an outlet 3 respectively arranged at both ends of the box 1, and a water inlet pipe 4 connected to the box 1, and also includes a fogger 6 and a fan 7 respectively connected to the box 1, the fogger 6 is used to generate mist in the box 1 to cool the pipe, and the fan 7 is used to increase the fluidity of the mist in the box 1.

[0036] When the pipe is cooled, it enters the box body 1 through the feed port 2. The fogger 6 in the box body 1 uses cooling water to generate mist. The fan 7 blows the mist to increase the floating effect of the mist, increase the fluidity of the mist, and make the mist fill the inside of the box body 1, and then make the mist evenly distributed on the surface of the pipe, so as to achieve a uniform and rapid cooling effect. After cooling, the pipe moves out through the discharge port 3. Further, a plurality of foggers 6 are provided in the box body 1 to ensure the concentration of the mist and the cooling effect. At the same time, the foggers 6 are evenly distributed in the box body 1, and a high-power ultrasonic fogger 6 is used; further, the box body 1 is connected to a plurality of fans 7 to fully stir the air in the box body 1 to ensure that the mist fills the internal space of the box body 1; further, the fan 7 is a waterproof fan 7, and the air inlet of the fan 7 is connected to an air filter 17, and the dust or impurities in the air are filtered out by the air filter 17 to avoid the contamination of the cooling water.

[0037] Beneficial effects of this embodiment: a fogger 6 is provided to produce mist using cooling water, and the mist is then blown by the fan 7 to fill the entire box 1, so that the mist can fully contact the surface of the pipe, and the pipe is fully and evenly cooled, thereby avoiding deformation of the pipe due to uneven cooling and ensuring the overall roundness of the pipe. At the same time, under the uniform cooling effect of the fog, the performance indicators such as the tensile yield stress, impact strength and elongation at break of the pipe are also better, thereby improving the production quality of the pipe.

[0038] Example 2

[0039] like Figure 1-3 As shown, this embodiment is based on Embodiment 1, and the difference from Embodiment 1 is that:

[0040] The bottom of the box body 1 is provided with a mounting hole, the fogger 6 is installed on the mounting hole and the wire of the fogger 6 is located outside the box body 1. A sealing ring 8 is provided between the fogger 6 and the mounting hole. It also includes a valve 5 installed on the water inlet pipe 4, a first water level sensor 9 and a second water level sensor 10 installed on the box body 1, a drain pipe 11 connected to the box body 1, a pump body 12 connected to the drain pipe 11 and a temperature sensor 13 installed in the box body 1. The first water level sensor 9 is connected to the valve 5 by signal. The first water level sensor 9 is used to detect the lowest water level in the box body 1, the second water level sensor 10 is used to detect the highest water level in the box body 1, and the temperature sensor 13 is connected to the valve 5 and the pump body 12 by signal.

[0041] The fogger 6 is installed at the bottom of the water tank through the mounting hole. When in use, the cooling water in the water tank covers the fogger 6. At the same time, the wires connected to the fogger 6 are arranged outside the box body 1. The existing fogger 6 is generally directly immersed in the water, and part of the wires connected to it are also immersed in the water. The cooling water of this device needs to cool the pipe. During the cooling process, the temperature of the cooling water itself will rise. At this time, if the wires are immersed in water, the wires will accelerate aging under the immersion of warm water. There is a risk of leakage after long-term use. This problem can be avoided by arranging the wires outside the box body 1. In order to prevent cooling water from leaking from the mounting hole, a sealing ring 8 is also provided between the fogger 6 and the mounting hole to increase the sealing between the fogger 6 and the box body 1. At the same time, during actual use, on the premise of ensuring that the fogger 6 is firmly installed, sealant will be applied to the mounting hole to fully prevent the box body 1 from leaking. A first water level sensor 9 is provided to detect the lowest water level of cooling water. When the cooling water level is lower than the set value, the valve 5 is automatically opened, and the cooling water enters the box body 1 through the water inlet pipe 4 to prevent the water level from being too low and the mist generator 6 from being unable to mist, thereby preventing production hazards caused by human error in not replenishing the cooling water to the box body 1 in time and thus avoiding unnecessary losses. A second water level sensor 10 is provided to detect the highest water level of cooling water. When the cooling water level is higher than the set value, the valve 5 is automatically closed if it is not closed, and at the same time the pump body 12 is started to discharge the excess cooling water through the drain pipe 11 to prevent the water level from being too high. After the mist from the fogger 6 cools the pipe, it is directly evaporated or adheres to the surface of the pipe to form a water film and then drips into the box 1. After a long period of cooling, the cooling water in the box 1 will gradually heat up. In order to avoid the cooling water temperature being too high, a temperature sensor 13 is installed in the box 1. At the same time, the temperature sensor 13 is connected to the pump body 12 and the valve 5 signal. When the temperature sensor 13 detects that the temperature in the box 1 is too high, the valve 5 and the pump body 12 are opened at the same time, the pump body 12 discharges the high-temperature cooling water, and the valve 5 opens the water inlet pipe 4 to inject cooling water with a lower temperature, thereby lowering the temperature of the cooling water in the box 1 to ensure the normal cooling work.

[0042] The remaining features and working principles of this embodiment are consistent with those of Embodiment 1.

[0043] Example 3

[0044] like Figure 1-4 As shown, this embodiment further limits embodiment 1 or embodiment 2 on the basis of embodiment 1 or embodiment 2, and the difference is that:

[0045] It also includes a pipe diameter adapter ring 14 respectively installed on the feed port 2 and the discharge port 3, and a sewage pipe 15 arranged at the bottom of the box body 1. The pipe diameter adapter ring 14 and the feed port 2 and the discharge port 3 are all detachable structures. The pipe diameter adapter ring 14 is made of elastic material and the inner side is used to fit with the outer surface of the pipe. The center of the opening of the pipe diameter adapter ring 14 is not higher than the center of the feed port 2 or the discharge port 3 in the vertical direction, and a plug 16 is connected to the end of the sewage pipe 15.

[0046] This device uses a fogger 6 in conjunction with a fan 7 to cool the pipe, and is applicable to pipes of different diameters. Therefore, a detachable pipe diameter adapter ring 14 is installed at the inlet 2 and outlet 3 of the box 1. When it is necessary to cool pipes of different diameters, the pipe diameter adapter ring 14 with corresponding opening sizes can be replaced, which meets the support and guidance requirements of pipes of different diameters, so that this device can meet the cooling work of pipes of various sizes. The pipe diameter adapter ring 14 is set to an elastic material and fits the pipe. During the movement of the pipe, the pipe diameter adapter ring 14 scrapes away the water on the surface of the pipe to prevent excessive moisture from being carried by the pipe surface to the outside of the box 1. Specifically, the pipe diameter adapter ring 14 can be made of rubber or silicone. The diameters of the feed inlet 2 and the discharge port 3 of the box body 1 are fixed. When the diameter of the pipe is large, the opening of the pipe diameter adapter ring 14 is concentric with the feed inlet 2 or the discharge port 3. Since the pipe diameter adapter ring 14 itself is made of elastic material, elastic deformation will occur. Therefore, when the diameter of the pipe is small, such as Figure 4 As shown, the opening center of the pipe diameter adapter ring 14 is set directly below the center of the inlet 2 or the outlet 3, thereby reducing the area of ​​the elastic material below the opening of the pipe diameter adapter ring 14, reducing the elastic deformation of the pipe diameter adapter ring 14, ensuring the support of the pipe by the pipe diameter adapter ring 14, and also ensuring that the opening of the pipe diameter adapter ring 14 can always fit the surface of the pipe to ensure the water scraping effect on the pipe. During the long-term use of this device, impurities are inevitably present in the cooling water. The sewage pipe 15 is set to discharge the cooling water and impurities together to avoid excessive impurities in the water affecting the cooling work. At the same time, the plug 16 can also be set as a valve 5. The sewage discharge effects of the two are similar. Further, the box body 1 is provided with a window 18, and the window 18 is made of a transparent material to facilitate the observation of the cooling water.

[0047] The rest of the working principle and working process of this embodiment are consistent with those of Embodiment 1 or Embodiment 2.

[0048] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
