Description

Technical Field

[0001] This utility model relates to the field of pipeline production technology, specifically to an all-around cooling device based on pipeline production. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. Typically, after being pressurized by blowers, compressors, pumps, boilers, etc., the fluid flows from the high-pressure area to the low-pressure area in the pipeline. It can also be transported using the fluid's own pressure or gravity. Pipelines have a wide range of applications, mainly used for water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering, and various industrial installations.

[0003] Because pipes are produced by high-temperature extrusion molding, they need to be cooled in time after molding. Cooling has the benefits of controlling material properties, improving surface quality, increasing production efficiency, ensuring dimensional accuracy, eliminating internal stress, and preventing thermal damage.

[0004] For example, CN218749235U discloses a utility model patent for a cooling device for PVC pipe production, which includes a machine body, a conveying roller fixedly installed inside the machine body, an inlet and an outlet respectively opened on both sides of the machine body, a three-way pipe installed on the top of the inner cavity of the machine body, a nozzle installed at the output end of the three-way pipe, a water pump and a water tank assembled on the top of the machine body, and a circulating water inlet pipe and a water outlet pipe opened on the surface of the water tank.

[0005] Pipes are usually formed by high-temperature extrusion, so the entire pipe is in a high-temperature state during extrusion. As mentioned in the patent above, some existing technologies use nozzles to spray water onto the top of the pipe to cool it down. However, the bottom of the pipe is not easily exposed to cooling water, which leads to reduced cooling efficiency and uneven cooling, causing greater internal stress in the pipe, affecting the uniformity of material properties, and may even cause pipe deformation. Utility Model Content

[0006] The purpose of this invention is to provide an all-around cooling device based on pipeline production to address the aforementioned shortcomings in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an all-around cooling device based on pipeline production, comprising a cooling box, wherein four cooling rings are fixedly arranged inside the cooling box, each cooling ring is sleeved on the outer wall of the pipeline, and multiple spray heads are fixedly arranged on the inner ring of each cooling ring. Two limiting rods are fixedly arranged inside the cooling box, and a squeezing plate is slidably arranged on each limiting rod. Telescopic water bags are fixedly arranged on both sides of each squeezing plate, and a connecting pipe is fixedly connected to each cooling ring on the side of each telescopic water bag away from the squeezing plate.

[0008] Preferably, four turntables are rotatably arranged inside the cooling box, and a transmission steel belt is fitted over the four turntables. Two extrusion plates are fixedly connected to the transmission steel belt.

[0009] Preferably, a reciprocating screw is rotatably mounted inside the cooling box, and a servo motor fixedly connected to the reciprocating screw is fixedly mounted on the outer wall of the cooling box. A moving block is mounted on the reciprocating screw, and a connecting block is fixedly mounted on the moving block. The connecting block is fixedly connected to the transmission steel belt.

[0010] Preferably, the movable block is fixedly provided with an abutment ball adapted to the reciprocating screw.

[0011] Preferably, a water collection trough is fixedly provided at the bottom of the cooling water tank, and a water suction pipe is fixedly connected to the end of each telescopic water bladder away from the extrusion plate.

[0013] Preferably, a scraper ring is fixedly installed on the outer wall of the cooling box, and two conveying columns are rotatably installed inside the cooling box.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-6A comprehensive cooling device for pipeline production, the technical solution proposed in this utility model includes a cooling box 1, inside which four cooling rings 15 are fixedly installed. Each cooling ring 15 is sleeved on the outer wall of the pipeline. Multiple spray heads 20 are fixedly installed on the inner ring of each cooling ring 15. Two limiting rods 17 are fixedly installed inside the cooling box 1. A squeezing plate 12 is slidably installed on each limiting rod 17. Telescopic water bags 13 are fixedly installed on both sides of each squeezing plate 12. The side of each telescopic water bag 13 away from the squeezing plate 12 is fixedly connected to each cooling ring 15 in a one-to-one correspondence. Connector 14; The extrusion plate 12 is limited by the limiting rod 17, so that the extrusion plate 12 can only slide along the limiting rod 17. Four support rods 5 are fixedly installed inside the cooling box 1, and the four support rods 5 are fixedly connected to four cooling rings 15 one-to-one, supporting the cooling rings 15. Each cooling ring 15 is hollow inside, and each spray head 20 is fixedly connected to the corresponding cooling ring 15. The spray heads 20 are evenly arranged in the inner ring of the cooling ring 15. One end of the connecting pipe 14 is fixedly connected to the telescopic water bag 13, and the other end is fixedly connected to the cooling ring 15. Figure 3 As shown, two of the four cooling rings 15 are on the right and two are on the left. When a pipe to be cooled passes through each cooling ring 15, the extrusion plates 12 are moved. When the extrusion plate 12 moves to the right, the cooling water in the right-side telescopic water bladder 13 is squeezed into the corresponding cooling ring 15 through the connecting pipe 14, and then sprayed out through the spray nozzles 20 on the cooling ring 15. The spray nozzles 20 are arranged in a circle around the inner ring of the cooling ring 15, so that the pipe can be cooled from both the top and bottom. When the right-side telescopic water bladder 13 is compressed and shortened, the left-side telescopic water bladder 13 is stretched. The pressure plate 12 extends, creating a negative pressure inside the tube, drawing cooling water into the left telescopic water bladder 13. Once the water in the right telescopic water bladder 13 is discharged, the pressure plate 12 moves to the left. At this time, the cooling water in the left telescopic water bladder 13 is squeezed into the cooling ring 15 through the connecting pipe 14 and discharged. Meanwhile, the right telescopic water bladder 13 generates a negative pressure, drawing cooling water into it. By controlling the left and right movement of the pressure plate 12, cooling water can be continuously sprayed out from the cooling ring 15, thus providing all-around cooling for the pipeline.

[0026] Specifically, four turntables 10 are rotatably arranged inside the cooling box 1. A transmission steel belt 11 is fitted over each of the four turntables 10, and two extrusion plates 12 are fixedly connected to the transmission steel belt 11. The four turntables 10 are evenly distributed above the telescopic water bladder 13. The transmission steel belt 11 is located on the outer circumference of the four turntables 10, and is supported by the four turntables 10. The top of the extrusion plates 12 is fixedly connected to the transmission steel belt 11 above them. The transmission steel belt 11 is in a taut state. When cooling of the pipe is required, pulling the transmission steel belt 11 simultaneously moves the two extrusion plates 12. Figure 3As shown, when the lower extrusion plate 12 moves to the right, the upper extrusion plate 12 moves to the left; when the lower extrusion plate 12 moves to the left, the lower extrusion plate 12 moves to the right, thereby compressing the telescopic water bladders 13 at different positions, so that cooling water is sprayed out from both ends of the pipe at all times, thereby cooling the pipe in all directions.

[0027] Specifically, a reciprocating screw 7 is rotatably installed inside the cooling box 1, and a servo motor 2 is fixedly installed on the outer wall of the cooling box 1 and fixedly connected to the reciprocating screw 7. A moving block 8 is installed on the reciprocating screw 7, and a connecting block 9 is fixedly installed on the moving block 8. The connecting block 9 is fixedly connected to the transmission steel belt 11. The output end of the servo motor 2 is fixedly connected to the reciprocating screw 7. The servo motor 2 drives the reciprocating screw 7 to rotate. When the reciprocating screw 7 rotates, it drives the moving block 8 to move back and forth, thereby driving the transmission steel belt 11 to move through the connecting block 9, which in turn causes the two extrusion plates 12 to move, thereby spraying the cooling water in the telescopic water bag 13 onto the pipe.

[0028] Specifically, the movable block 8 is fixedly provided with an abutment ball 21 that is adapted to the reciprocating screw 7; the abutment ball 21 is adapted to the reciprocating thread groove of the reciprocating screw 7, and the movable block 8 is slidably connected to the cooling box 1. When the reciprocating screw 7 rotates, the movable block 8 moves back and forth along the reciprocating screw 7 through the cooperation of the abutment ball 21 and the reciprocating thread groove, thereby driving the transmission steel belt 11 to move.

[0029] Specifically, a water collection tank 4 is fixedly installed at the bottom of the cooling water tank, and a suction pipe 16 is fixedly connected to the end of each telescopic water bladder 13 away from the extrusion plate 12. The water collection tank 4 is used to collect the cooling water falling from the pipe. The bottom of the suction pipe 16 extends into the bottom of the water collection tank 4. When a negative pressure is generated in the telescopic water bladder 13, the cooling water in the water collection tank 4 can be drawn into the telescopic water bladder 13 through the suction pipe 16, which facilitates subsequent spraying. At the same time, the cooling water in the water collection tank 4 can be recycled. If the temperature of the cooling water in the water collection tank 4 is high, the cooling water in the water collection tank 4 can be replaced to continue cooling without the need for water pumps or other equipment, thus reducing cooling costs.

[0030] Specifically, each suction pipe 16 is fixedly equipped with a second one-way valve 19 at the end away from the telescopic water bladder 13, and each connecting pipe 14 is fixedly equipped with a first one-way valve at the end near the telescopic water bladder 13. The second one-way valve 19 ensures that water in the water collection tank 4 can only enter the suction pipe 16, thereby preventing cooling water from flowing back into the water collection tank 4. The first one-way valve 18 ensures that the cooling chamber in the telescopic water bladder 13 can only enter the connecting pipe 14 and be sprayed out through the cooling ring 15 and the spray head 20.

[0031] Specifically, a scraper ring 3 is fixedly installed on the outer wall of the cooling box 1, and two conveying columns 6 are rotatably installed inside the cooling box 1. The scraper ring 3 is made of flexible material and its inner ring abuts against the outer wall of the pipe. The conveying columns 6 support the pipe moving inside the cooling box 1. The cooling box 1 has through holes at both ends for the pipe to pass through. When the pipe spraying cooling water passes through the cooling box 1, the scraper ring 3 scrapes off the cooling water adhering to the pipe, thereby ensuring the cleanliness of the pipe.

[0032] 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.
