Description

Technical Field

[0001] The utility model relates to the technical field of Mpp pipe production, in particular to a spray cooling device for Mpp pipes. Background Art

[0002] MPP pipes, also known as MPP power cable protection pipes, are divided into excavation type and non-excavation type. MPP non-excavation pipes are also called MPP jacking pipes or dragging pipes. MPP pipes are mainly made of modified polypropylene and have the characteristics of high temperature resistance and external pressure resistance. They are suitable for medium and low voltage power transmission line cable duct pipes below 10KV.

[0003] Traditional MPP pipes need to be cooled and shaped during the processing. However, when the existing cooling and shaping devices cool MPP pipes, they cannot be applied to MPP pipes with different pipe diameters, resulting in shaking of MPP pipes with inappropriate pipe diameters during transportation, leading to poor cooling effect on MPP pipes.

[0004] The existing patent (Publication No.: CN222768820U) discloses a cooling and shaping device for MPP pipes. The utility model transports the pipe fittings at the top of the support rollers in cooperation with external pipe fitting traction equipment, and adjusts the position of the guiding mechanism through the telescoping of the push rod motor and the telescoping of the telescopic rod, so that the guiding mechanisms on both sides are in contact with the outer pipe wall of the pipe fitting, enabling the guiding mechanism to maintain a straight transportation path when moving on the support rollers, thereby keeping the cooling effect stable and good.

[0005] In view of the above problems, the existing patent gives a solution. Although it can keep the straight transportation path of the pipe material, thus keeping the cooling effect stable and good, the adopted spraying method is top spraying, which easily leads to insufficient cooling at the bottom of the MPP pipe, thus easily causing problems such as excessive ovality and surface stress concentration, and the water after spraying is directly recycled, and the impurities contained therein will affect the surface quality of the pipe material.

[0006] Therefore, a spray cooling device for Mpp pipes is proposed. Content of the Utility Model

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0028] A spray cooling device for Mpp pipes, including a circulating water tank 1, a housing 9 is bolted to the top of the circulating water tank 1, a number of partitions 2 are bolted inside the circulating water tank 1, and a filtering component 3 is arranged inside the circulating water tank 1. A spray cooling component 4 is bolted inside the housing 9, and the spray cooling component 4 includes a spraying part 41 and an adjusting part 42. The top of the spraying part 41 is communicated with a circulating pipe 5, and the other end of the circulating pipe 5 extends into the circulating water tank 1;

[0029] The spraying part 41 includes a flow guide plate 411 and a flow dividing plate 412. Both the flow guide plate 411 and the flow dividing plate 412 are at the top of the inner wall of the housing 9, and they are communicated with each other. The adjusting part 42 is arranged on the top of the partition 2, and two arc-shaped plates 413 are bolted to the front side and the rear side of the adjusting part 42 respectively. The inner wall of the arc-shaped plate 413 is communicated with a spray head 414.

[0030] In this embodiment: By setting the spray cooling component 4, the flow guide plate 411 and the flow dividing plate 412 in the spraying part 41 cooperate with each other to evenly distribute the circulating water to each spray head 414, ensuring that the Mpp pipe can be evenly sprayed during the cooling process. The setting of the adjusting part 42 enables the arc-shaped plate 413 to be flexibly adjusted according to the diameter of the Mpp pipe, ensuring that the spray head 414 maintains a proper distance from the surface of the Mpp pipe. This not only can spray-cool the Mpp pipe in all directions and without dead angles, avoiding local under-cooling or over-cooling, but also can effectively prevent the problem of the Mpp pipe shaking during transportation caused by inappropriate pipe diameter, improving the cooling effect and cooling quality, ensuring the roundness and surface quality of the Mpp pipe, and reducing the occurrence of problems such as excessive ovality and surface stress concentration; By setting the filtering component 3, the water after spraying can be filtered. When the filtered circulating water is used for spray cooling again, it will not affect the surface quality of the pipe material due to impurities in the water adhering to the surface of the Mpp pipe, ensuring the appearance quality and performance of the Mpp pipe. At the same time, it also reduces the equipment failure caused by the blockage of the spray head 414 by impurities and extends the service life of the spray cooling device.

[0031] Specifically, as Figure 4 shown, the adjusting part 42 includes two arc-shaped adjusting plates 421 arranged symmetrically up and down. Both sides of the arc-shaped plate 413 are bolted with connecting blocks 422, and a bidirectional lead screw 423 threadedly penetrates through the inside of the connecting block 422. The bottom of the bidirectional lead screw 423 is rotatably connected to the partition 2 through a bearing seat.

[0032] Specifically, as Figure 4As shown, the surface of the bidirectional screw rod 423 is provided with threads with opposite rotation directions, and the interior of the connecting block 422 is provided with a threaded hole adapted to the bidirectional screw rod 423, and the two ends of the bidirectional screw rod 423 respectively pass through the corresponding connecting block 422 and are threadedly connected to the threaded hole.

[0033] Specifically, Figure 4 As shown, a supporting roller 424 is rotatably provided inside the arc-shaped adjustment plate 421 , and the supporting roller 424 is distributed inside the arc-shaped adjustment plate 421 in a ring shape.

[0034] In this embodiment: by setting the adjustment member 42, when it is necessary to adjust the position of the arc plate 413 to adapt to Mpp pipes of different diameters, the motor is driven by an external driving device to drive the bidirectional screw rod 423 to rotate. Since the surface of the bidirectional screw rod 423 is provided with threads with opposite rotation directions and adapted to the threaded holes inside the connecting block 422, when the bidirectional screw rod 423 rotates, it drives the connecting blocks 422 on both sides to move along the screw rod, thereby making the two arc adjustment plates 421 approach or move away from each other, adjusting the position and spacing of the arc plate 413, and being able to conveniently and quickly adjust the position of the arc plate 413 to achieve adaptation to Mpp pipes of different diameters, thereby improving the versatility and applicability of the device, and the setting of the support roller 424 reduces the friction of the Mpp pipe during the cooling process, thereby avoiding damage to the surface of the Mpp pipe due to friction, and also helps to maintain the linear transportation of the Mpp pipe, and cooperates with the adjustment of the arc plate 413 to further improve the cooling effect and the quality of the Mpp pipe.

[0035] Specifically, Figure 5 As shown, the filter assembly 3 includes a filter box 31, which is located between adjacent partitions 2 and the inner wall of the partition 2 and the circulating water tank 1. The interior of the filter box 31 is bolted with a coarse filter 32, a fine filter 33 and an activated carbon adsorption layer 34 from top to bottom. A mounting plate 35 is bolted between the left sides of several filter boxes 31, and the mounting plate 35 is located on the outside of the circulating water tank 1 and bolted thereto.

[0036] Specifically, Figure 5 As shown, the front and rear sides of the filter box 31 are bolted with limit blocks 6, and the surfaces of the limit blocks 6 are in sliding contact with the inner walls of the partition 2 and the circulating water tank 1 respectively, and an opening is set between the bottom of the inner wall of the partition 2 and the circulating water tank 1.

[0037] In this embodiment: By providing a filtering component 3, after the use of the circulating water tank 1, it successively passes through the coarse filter screen 32, fine filter screen 33, and activated carbon adsorption layer 34 inside the filter box 31. The coarse filter screen 32 first intercepts larger impurities, then the fine filter screen 33 filters smaller particulate impurities, and finally the activated carbon adsorption layer 34 adsorbs odors, pigments, and tiny harmful substances in the water. The purified water is pumped into the circulation pipe 5 by a liquid pump preset in the circulating water tank 1 to continue participating in the circulation. The use of a multi-stage filtering structure can comprehensively and effectively purify the circulating water, ensure the cleanliness of the circulating water, prevent impurities from having an adverse impact on the surface quality of the Mpp pipe, and at the same time reduce the damage to the equipment caused by impurities, extending the service life of the entire spray cooling device; and the design of the limit block 6 facilitates the installation and disassembly of the filter box 31, making it convenient to maintain and replace the filtering component 3; the opening design at the bottom of the circulating water tank 1 and the partition 2 ensures the smooth flow of water, ensures the normal progress of the filtering process, and improves the filtering efficiency.

[0038] Specifically, as Figure 3 shown, the top arc plate 413 is connected to the flow dividing plate 412 through a hose, and a bellows 7 is provided between the two arc plates 413 at the top and bottom.

[0039] Specifically, as Figure 3 shown, a flow channel 8 is provided inside the arc plate 413, and the flow channel 8 is respectively connected to the bellows 7 and the nozzle 414.

[0040] In this embodiment: Through the use of the hose, bellows 7, and flow channel 8, when the arc plate 413 adjusts its position, the connection of the water flow is not affected, ensuring that the nozzle 414 can continuously and stably spray and cool the Mpp pipe, and at the same time enhancing the flexibility and reliability of the device during the adjustment process.

[0041] Working principle: When the Mpp pipe is subjected to spray cooling treatment, when the extruded and formed Mpp pipe enters the device, it is conveyed into the interior of the housing 9 along a preset track, preparing to receive spray cooling. The cooling water in the circulating water tank 1 is conveyed to the guide plate 411 in the spray member 41 through the circulating pipe 5 under the action of the liquid pump. After the guide plate 411 initially guides the water flow, it is conveyed to the shunt plate 412. The shunt plate 412 further evenly distributes the circulating water, and the water is shunted to the top arc plate 413 through a hose, and then through the corrugated pipe 7 between the top and bottom arc plates 413, the water is conveyed to the flow channels 8 inside each arc plate 413, and finally sprayed out from the nozzles 414 to perform all-round and uniform spray cooling on the Mpp pipe. The cooling water sprayed out from the nozzles 414 covers the surface of the Mpp pipe, absorbs the heat of the Mpp pipe, reduces the temperature of the Mpp pipe, and completes the cooling process. The water after spraying falls into the circulating water tank 1 and passes through the coarse filter screen 32, the fine filter screen 33 and the activated carbon adsorption layer 34 in sequence. The coarse filter screen 32 first intercepts larger impurities in the water, such as particles, debris, etc.; the fine filter screen 33 further filters smaller particle impurities; the activated carbon adsorption layer 34 adsorbs the peculiar smell, pigments and tiny harmful substances in the water. The water purified through multi-stage filtration, under the action of the liquid pump, is conveyed to the spray member 41 through the circulating pipe 5 again to participate in the next round of spray cooling cycle; when it is necessary to cool Mpp pipes with different pipe diameters, the controller on the housing 9 controls the externally connected drive motor to drive the bidirectional lead screw 423 to rotate. Since the surface of the bidirectional lead screw 423 has threads with opposite helix directions and is adapted to the threaded holes inside the connecting block 422, when the bidirectional lead screw 423 rotates, the two connecting blocks 422 move along the bidirectional lead screw 423, thereby driving the two arc-shaped adjusting plates 421 to approach or move away from each other. As the position of the arc-shaped adjusting plate 421 is adjusted, the arc plate 413 also changes its position and spacing accordingly until it is adapted to the pipe diameter of the Mpp pipe. At this time, the nozzles 414 on the inner wall of the arc plate 413 maintain a suitable distance from the surface of the Mpp pipe to ensure the spray cooling effect. At the same time, the support rollers 424 inside the arc-shaped adjusting plate 421 contact the Mpp pipe, reducing the friction force of the Mpp pipe during the cooling process, avoiding surface damage, and also assisting in maintaining the straight conveyance of the Mpp pipe.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
