Abstract
Description
Technical Field
[0001] This utility model relates to the field of cooling equipment, and in particular to a spray cooling box for MPP power pipes after forming. Background Technology
[0002] MPP power conduit, short for modified polypropylene power conduit, is a type of pipe specifically designed for power engineering. MPP power conduit boasts high compressive strength, capable of withstanding soil and ground pressure, as well as vehicle loads, and is resistant to deformation, ensuring the safe operation of power cables. For example, during road construction, even when large construction machinery operates on the surface, the buried MPP power conduit remains intact.
[0003] After MPP power pipes are manufactured, uneven cooling can lead to uneven distribution of microstructures such as crystallinity and orientation. Relying solely on spraying from the left and right sides makes it difficult to ensure that all parts of the pipe's circumference receive an equal amount of cooling water. This can result in inconsistent cooling rates in different parts of the pipe, causing defects such as unevenness, wrinkles, or pitting on the pipe surface, affecting its appearance quality. It can also increase the surface roughness of the pipe, impacting its overall service life and safety. During the spray cooling process, the coolant comes into contact with debris, dust, and impurities from the production environment on the surface of the MPP power pipe. These impurities accumulate in the coolant, making it turbid. These impurities gradually clog the spray nozzles in the cooling tank, reducing the coolant flow rate. The used coolant is still at a high temperature; direct discharge without treatment leads to significant heat waste, prolongs the cooling time of the pipes, increases labor costs, disrupts production schedules due to equipment downtime for cleaning, increases the frequency of equipment maintenance and replacement, raises maintenance costs, reduces production efficiency, and increases energy consumption. Utility Model Content
[0004] The main purpose of this utility model is to provide a spray cooling box after MPP power pipe forming, which can effectively solve the problems of unevenness, wrinkles or pitting on the surface of the pipe, which affect the appearance quality of the pipe, and may also increase the surface roughness of the pipe, affecting the overall service life and safety of the pipe, as well as increasing labor costs, affecting production progress due to equipment downtime for cleaning, increasing the frequency of equipment maintenance and replacement, increasing maintenance costs, leading to decreased production efficiency and increased energy consumption.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray cooling box for MPP power pipe forming, comprising a cooling box, a partition plate fixedly connected inside the cooling box, a support plate fixedly connected to the rear side wall inside the cooling box, the support plate being disposed at the bottom of the partition plate, a pump fixedly connected to the top of the support plate, a first water inlet pipe fixedly connected to the input end of the pump, a connecting pipe fixedly connected to the output end of the pump, a conveying pipe communicating with the top end of the connecting pipe, and a top plate fixedly connected to the top of the cooling box.
[0006] Furthermore, a support base is fixedly connected to the top of the top plate, and a spray ring is fixedly connected inside the support base. The top end of the conveying pipe is connected to the bottom of the spray ring, and nozzles are connected inside the spray ring.
[0007] Furthermore, each of the top plates is fixedly connected to a guide plate, and two guide plates are arranged on the front and rear sides of the support base. Brackets are fixedly connected to the bottom of the left and right sides of the top plate and the top inner wall of the cooling box.
[0008] Furthermore, each of the two brackets has an outer frame at its top, and a sieve plate is fixedly connected inside each of the two outer frames.
[0009] Furthermore, a circulation pump is installed on the right side wall of the cooling box, and an upper pipe is fixedly connected to the input end of the circulation pump. The left end of the upper pipe is located on the top right side of the partition plate, and a second water inlet pipe is connected through the left side of the front side wall of the cooling box.
[0010] Furthermore, the output end of the circulating pump is fixedly connected to a lower pipe, which is connected through the right side wall of the cooling box and is located on the top right side of the partition plate.
[0011] Furthermore, a waste discharge pipe is connected through the left side wall of the cooling box. The waste discharge pipe is located on the top left side of the partition plate, and a guide rail groove is opened inside the waste discharge pipe.
[0012] Furthermore, a baffle is slidably connected inside the guide rail groove, and a handle is fixedly connected to the right side wall of the baffle through the front side wall of the cooling box.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. This utility model, through its pump, first inlet pipe, delivery pipe, support base, spray ring, and nozzles, solves the problems that cause defects such as unevenness, wrinkles, or pitting on the pipe surface, affecting the appearance quality of the pipe and potentially increasing surface roughness, thus impacting the overall service life and safety of the pipe. Cooling water is delivered to the spray ring via the connecting pipe and delivery pipe. The spray ring has a ring-shaped structure with nozzles evenly distributed inside. When the pipe enters the spray ring, the nozzles spray cooling water evenly from different angles and directions, providing comprehensive cooling to the pipe. The cooling water sprayed from the nozzles directly covers the surface of the MPP power pipe, rapidly removing heat through heat exchange. This effectively ensures that the entire circumference of the pipe receives cooling water simultaneously and evenly, improving the appearance quality of the pipe, making the surface smoother and reducing surface roughness.
[0015] 2. By incorporating a bracket, outer frame, sieve plate, circulating pump, lower pipe, and upper pipe, this system addresses issues that increase labor costs, disrupt production schedules due to equipment downtime for cleaning, increase the frequency of equipment maintenance and replacement, raise maintenance costs, reduce production efficiency, and increase energy consumption. The sieve plate inside the outer frame pre-filters the returning cooling water, intercepting impurities such as debris and dust remaining on the surface of electrical conduits. The filtered cooling water passes through the sieve plate and falls back above the partition plate inside the cooling tank. The circulating pump starts, drawing cooling water from above the partition plate through the upper pipe and returning it to the area below the partition plate inside the cooling tank via the lower pipe. This achieves water recycling, conserves water resources, ensures continuous cooling, effectively improves heat exchange efficiency, accelerates pipe cooling, helps increase production efficiency, reduces equipment maintenance costs and frequency, and extends the overall service life of the cooling equipment.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figure 1 - Figure 3 As shown: A spray cooling box for MPP power pipe forming includes a cooling box 1. A partition plate 2 is fixedly connected inside the cooling box 1. The partition plate 2 divides the interior of the cooling box 1 into two areas: the top area is for collecting the heated cooling water after use, and the bottom area is for storing unused coolant.
[0027] A support plate 3 is fixedly connected to the rear inner wall of the cooling box 1. The support plate 3 is located at the bottom of the partition plate 2, and a pump 4 is fixedly connected to the top of the support plate 3. The support plate 3 provides bottom support for the pump 4 and fixes the pump 4 to the top of the support plate 3. A first water inlet pipe 5 is fixedly connected to the input end of the pump 4, and a connecting pipe 6 is fixedly connected to the output end of the pump 4. A conveying pipe 7 is connected to the top end of the connecting pipe 6. A top plate 8 is fixedly connected to the top of the cooling box 1, and a support base 9 is fixedly connected to the top of the top plate 8. A spray ring 10 is fixedly connected inside the support base 9. The top end of the conveying pipe 7 is connected to the bottom of the spray ring 10, and spray nozzles 11 are connected to the inside of the spray ring 10. The top plate 8 fixedly connected to the top of the cooling box 1 supports the top device, and the support base 9 on the top of the top plate 8 supports and fixes the bottom of the spray ring 10 to prevent spraying. If ring 10 falls off, etc., unused coolant is extracted from the cooling tank 1 through the first water inlet pipe 5 at the input end of pump 4. The extracted coolant is connected to the delivery pipe 7 through the connecting pipe 6 at the output end of pump 4, and the coolant is delivered to the interior of spray ring 10 through delivery pipe 7. The pump 4 releases a large pressure to make the coolant spray out from the nozzle 11 to cool the MPP power pipe that enters the interior of spray ring 10. In addition, the nozzle 11 sprays through atomization to ensure that the cooling water is sprayed evenly from different angles and directions to provide all-round spray coverage of the pipeline.
[0028] like Figure 1 - Figure 6 As shown, the top of the top plate 8 is fixedly connected with a guide plate 12. The two guide plates 12 are set on the front and rear sides of the support base 9. The guide plates 12 are used to guide the sprayed coolant, so that the coolant flows into the top of the internal partition plate 2 of the cooling box 1 for collection.
[0029] Brackets 13 are fixedly connected to the bottom of the left and right sides of the top plate 8 and the top inner wall of the cooling box 1. Each bracket 13 has an outer frame 14 on top, and a sieve plate 15 is fixedly connected inside the two outer frames 14. The brackets 13 support the bottom of the top outer frame 14 and connect the outer frame 14 to the sieve plate 15, so that the sieve plate 15 is placed on the top of the bracket 13 and set on the left and right sides of the top plate 8. When cooling the pipes, the used coolant is filtered to intercept falling impurities and prevent them from entering the interior of the cooling box 1.
[0030] like Figure 1 - Figure 4As shown, a circulation pump 16 is installed on the right side wall of the cooling tank 1. The input end of the circulation pump 16 is fixedly connected to an upper pipe 18. The left end of the upper pipe 18 is located on the top right side of the partition plate 2. A second water inlet pipe 19 is connected through the left side of the front side wall of the cooling tank 1. The output end of the circulation pump 16 is fixedly connected to a lower pipe 17. The lower pipe 17 is connected through the right side wall of the cooling tank 1 and is located on the top right side of the partition plate 2. After the used coolant collected at the top of the partition plate 2 reaches a certain level, the circulation pump 16 will be started to draw the coolant above the partition plate 2 through the upper pipe 18 and send it back to the area below the partition plate 2 inside the cooling tank 1 through the lower pipe 17, realizing the recycling of coolant, which saves water resources and ensures the continuous operation of the cooling process.
[0031] like Figure 1 - Figure 6 As shown, a drain pipe 20 is connected through the left side wall of the cooling tank 1. The drain pipe 20 is located on the top left side of the partition plate 2. A guide groove 21 is opened inside the drain pipe 20. A baffle 22 is slidably connected inside the guide groove 21. A handle 23 is fixedly connected through the right side wall of the baffle 22 to the front side wall of the cooling tank 1. When it is necessary to clean the top of the partition plate 2 or replace the coolant inside the cooling tank 1, the handle 23 is pulled, which causes the baffle 22 to slide in the guide groove 21 inside the drain pipe 20, opening the drain pipe 20. This allows the water containing impurities accumulated above the partition plate 2 in the cooling tank 1 and the filtered impurities to be discharged through the drain pipe 20. After cleaning, the handle 23 is pushed to close the baffle 22 to prevent coolant leakage, ensure that the coolant in the cooling tank 1 remains clean, and maintain the stable operation of the cooling system.
[0032] It should be noted that this utility model is a spray cooling box after MPP power pipe forming. First, the pump 4 and the circulation pump 16 are connected to the external power supply and control terminal to supply power to the device.
[0033] During the cooling process, the formed MPP power pipe is fed into the spray ring 10 inside the support base 9. External water is injected into the cooling tank 1 through the second inlet pipe 19. The pump 4 is activated, drawing cooling water from below the partition plate 2 within the cooling tank 1 through the first inlet pipe 5. This cooling water is then transported to the spray ring 10 via the connecting pipe 6 and the conveying pipe 7. The spray ring 10 has a ring-shaped structure with evenly distributed nozzles 11 inside. When the pipe enters the spray ring 10, the nozzles 11 spray cooling water evenly from different angles and directions, providing comprehensive cooling to the pipe. The cooling water sprayed from the nozzles 11 directly covers the surface of the MPP power pipe, rapidly removing heat through heat exchange.
[0034] After the cooling process is complete, the water circulation process begins. The cooled water flows along the surface of the MPP power pipe, over the top plate 8, and through the guide plate 12 to the outer frames 14 on both sides. The sieve plate 15 inside the outer frame 14 performs preliminary filtration of the returning cooling water, intercepting impurities such as debris and dust remaining on the surface of the power pipe. The filtered cooling water passes through the sieve plate 15 and falls back into the cooling tank 1 above the partition plate 2. The circulation pump 16 starts, drawing the cooling water above the partition plate 2 through the upper pipe 18 and returning it to the area below the partition plate 2 inside the cooling tank 1 through the lower pipe 17, thus achieving the recycling of cooling water, saving water resources, and ensuring the continuous operation of the cooling process.
[0035] Regarding impurity handling, as the cooling process continues, the amount of impurities intercepted by the sieve plate 15 gradually increases. When it is necessary to clean the impurities, pull the handle 23 to move the baffle 22 in the guide groove 21 inside the impurity discharge pipe 20, opening the impurity discharge pipe 20. This allows the water containing impurities accumulated above the partition plate 2 in the cooling box 1 and the filtered impurities to be discharged through the impurity discharge pipe 20. After cleaning, push the handle 23 to close the baffle 22 to prevent cooling water leakage, ensuring that the cooling water in the cooling box 1 remains clean and maintaining the stable operation of the cooling system.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
