Description

Technical Field

[0001] This utility model belongs to the field of plastic pipe cooling technology, specifically relating to a plastic pipe cooling box. Background Technology

[0002] During the extrusion molding process of plastic pipes, the plastic pipes need to be cooled and shaped. Current cooling devices generally use spray nozzles arranged in a ring on the outside of the pipe to cool the pipe by spraying cooling water.

[0003] However, the cooling method described above has the following drawbacks:

[0004] 1. Cooling the pipe by using spray heads arranged in a ring around the pipe requires multiple spray pipes and more nozzles, resulting in a complex piping system, increased water pump power, and increased cost and energy consumption.

[0005] 2. The nozzle is prone to clogging, increasing downtime for maintenance. Utility Model Content

[0006] This utility model addresses the aforementioned problems in the existing technology by proposing a plastic pipe cooling box that can meet the cooling requirements of pipes while saving costs and energy.

[0007] This utility model can be achieved through the following technical solutions:

[0008] A plastic pipe cooling box, comprising:

[0009] A housing having a receiving cavity, the housing being provided through both ends along its axial direction for the passage of pipes;

[0010] A support mechanism is installed inside the box, and the pipes are mounted on the support mechanism;

[0011] At least one nozzle is provided, and each nozzle is located at the top of the receiving cavity;

[0012] The cooling water sprayed from the nozzle first flows along the surface of the pipe and cools the pipe, and then flows down under gravity and accumulates at the bottom of the receiving cavity to cool the lower part of the pipe.

[0013] As a further improvement of this utility model, the spray nozzle of the nozzle is arranged in an arc shape and expands outward to form a guide port.

[0014] As a further improvement of this utility model, the nozzle is located at the top of the pipe and arranged along the axial direction of the pipe.

[0015] As a further improvement of this utility model, the support mechanism is arranged in multiple sets at intervals along the axial direction of the box body.

[0016] As a further improvement of this utility model, the support mechanism includes:

[0017] The meniscus forms an arc-shaped support surface and is used to support the lower part of the pipe;

[0018] Support feet, which are fixed inside the receiving cavity and connected to the meniscus.

[0019] As a further improvement of this utility model, it also includes a positioning mechanism, which comprises:

[0020] Fixed plates are disposed on both sides of the top of the receiving cavity;

[0021] The mounting rod has its two ends connected to the two fixing plates mentioned above;

[0022] A pressure roller is fitted onto the mounting rod, and the upper surface of the tube is in contact with the pressure roller.

[0023] As a further improvement of this utility model, the circumferential surface of the pressure roller is set as an inwardly concave arc surface and used to make contact with the surface of the pipe.

[0024] As a further improvement of this utility model, the concave arc surface of the pressure roller has the same curvature as the arc-shaped support surface of the meniscus, and forms a channel that matches the outer diameter of the tube.

[0025] As a further improvement of this utility model, the mounting rod is also provided with positioning fasteners, which are located on both sides of the pressure roller and close to the pressure roller.

[0026] As a further improvement of this utility model, a water outlet pipe is provided at the bottom of the box body, the water outlet pipe is connected to the receiving cavity, and the spray pipe and the water outlet pipe form a circulating cooling system.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. Reduced production costs and energy consumption: The nozzle is only located directly above the pipe, which not only simplifies the pipe layout but also reduces material usage and installation complexity, thereby reducing equipment manufacturing and installation costs and energy consumption.

[0029] 2. Improve cooling efficiency: The top spraying method first directly cools the upper part of the pipe. Then, the cooling water flows down under gravity and accumulates at the bottom of the receiving cavity to form a pool, which submerges the lower part of the pipe, thus achieving effective cooling of both the upper and lower parts. Furthermore, by adjusting the inlet and outlet water flow rates, it can adapt to the cooling needs of different pipe materials.

[0030] 3. Optimized nozzle design: The arc-shaped outward-expanding nozzle allows cooling water to cover the pipe surface more widely and evenly, maximizing the contact area between the cooling water and the pipe, thereby improving the utilization rate of cooling water resources. It can also guide the cooling water to flow in a specific direction, avoiding the problem of local overcooling or uneven cooling caused by the water flow directly impacting the pipe, ensuring that the entire pipe surface is cooled evenly, and also preventing nozzle blockage.

[0031] 4. Stable pipe conveying: The concave arc surface of the pressure roller has the same curvature as the arc-shaped support surface of the meniscus, forming a channel that matches the outer diameter of the pipe. This ensures that the pipe is always conveyed stably forward along its axial direction, improving the conveying accuracy of the pipe. At the same time, the setting of the pressure roller ensures that the pipe is always conveyed forward along the meniscus, and will not float up under the action of buoyancy, ensuring that the lower half of the pipe can be fully cooled, thus ensuring the uniform cooling of the entire pipe.

Detailed Implementation

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. The technical methods of the present invention will be further described, but the present invention is not limited to these embodiments.

[0035] like Figure 1 As shown, this utility model provides a plastic pipe cooling box, comprising:

[0036] The box 100 has a receiving cavity 101 inside, and the box 100 is provided with both ends through the axial direction for the pipe 200 to pass through.

[0037] The support mechanism 110 is installed inside the box 100, and the pipe 200 is mounted on the support mechanism 110 to ensure that the pipe 200 is transported forward stably.

[0038] At least one nozzle 120 is provided, and each nozzle 120 is located at the top of the receiving cavity. During the forward conveying of the pipe 200, the pipe 200 is cooled by the cooling water sprayed from each nozzle 120. In this embodiment, the scheme of providing only one nozzle 120 is described.

[0039] It is worth mentioning that in this embodiment, the nozzle 120 is not arranged along the circumference of the pipe 200, but is only set directly above the pipe 200. The overall pipeline system is simple, the water pump power is reduced, and thus the cost and energy consumption are reduced.

[0040] It should be noted that existing cooling devices generally use spray heads arranged in a ring around the outside of the pipe to cool the pipe by spraying cooling water. However, this method of cooling the pipe by spraying spray heads arranged in a ring around the pipe inevitably requires multiple spray pipes and more nozzles, which leads to a complex piping system, increased water pump power, and consequently increased costs and energy consumption.

[0041] Specifically, during the actual cooling process, the cooling water sprayed from the nozzle 120 flows along the surface of the pipe 200 and cools the pipe 200. However, this part of the cooling water can only cool the upper part of the pipe 200. Subsequently, the cooling water will flow down under the action of gravity and accumulate at the bottom of the receiving cavity 101 to form a pool, while the lower part of the pipe 200 is immersed in the pool, thereby cooling the lower part of the pipe 200.

[0042] This cooling box design has at least the following advantages:

[0043] 1. Reduced production costs and energy consumption: The nozzle 120 is only located directly above the pipe 200, which not only simplifies the pipe layout, but also reduces the amount of materials used and the complexity of installation, thereby reducing equipment manufacturing and installation costs, as well as energy consumption.

[0044] 2. Improve cooling efficiency: The upper part of the pipe 200 is directly cooled by top spraying. Then, the cooling water flows down under gravity and accumulates at the bottom of the receiving cavity 101 to form a water pool, which submerges the lower part of the pipe 200, thus achieving effective cooling of the upper and lower parts. Furthermore, by adjusting the inlet and outlet water flow rates, it can also adapt to the cooling needs of different pipe materials.

[0045] Preferably, the nozzle 121 of the nozzle 120 is arranged in an arc shape and expands outward to form a water flow guide. This design of the nozzle 121 has the following advantages:

[0046] 1. Optimize water flow distribution: The arc-shaped outward-expanding water nozzle 121 enables the cooling water to cover the surface of the pipe 200 in a wider and more uniform manner, ensuring that the contact area between the cooling water and the pipe 200 is maximized, thereby improving cooling efficiency;

[0047] 2. Uniform water flow spray: The design of the water flow guide can guide the cooling water to flow in a specific direction, avoiding the problem of local overcooling or uneven cooling caused by the water flow directly impacting the pipe 200, and ensuring that the entire surface of the pipe 200 is uniformly cooled.

[0048] 3. Reduce splashing: The arc-shaped outward expansion design helps control the direction and speed of the water flow, reducing splashing caused by high-speed impact during the spraying process and reducing water waste.

[0049] 4. Smooth transition: The nozzle 121 makes the cooling water transition more smoothly from the nozzle 120 to the surface of the pipe 200, reducing turbulence and resistance, ensuring that the cooling water can flow smoothly along the surface of the pipe 200, and improving the cooling effect.

[0050] 5. Prevent clogging: The arc-shaped, outward-expanding nozzle 121 increases the opening area, which can effectively prevent clogging.

[0051] Preferably, multiple sets of support mechanisms 110 are arranged at intervals along the axial direction of the housing 100. The multi-point support ensures the straightness and stability of the pipe 200 during forward conveying, while allowing the lower part of the pipe 200 to be immersed in the water pool at the bottom of the receiving cavity 101 to ensure its cooling effect.

[0052] Preferably, the support mechanism 110 includes:

[0053] The meniscus 111 forms an arc-shaped support surface and is used to support the lower part of the tube 200;

[0054] The support leg 112 is fixed inside the receiving cavity 101 and connected to the meniscus 111 to ensure the stability and firmness of the entire support mechanism 110 after installation;

[0055] Among them, the arc-shaped support surface of the meniscus 111 can closely fit the lower surface of the tube 200, providing stable support and preventing the tube 200 from shaking or shifting during the cooling process.

[0056] In addition, a seal (not shown in the figure) can be provided between the meniscus 111 and the pipe 200 to ensure that cooling water does not enter along the gap between the meniscus 111 and the pipe 200. This restricts the flow of cooling water on the surface of the pipe 200 and drips to the bottom of the receiving cavity 101 to form a pool, thus avoiding unnecessary loss of cooling water.

[0057] Preferably, it also includes a positioning mechanism 130, which comprises:

[0058] Fixing plates 131 are disposed on both sides of the top of the receiving cavity 101;

[0059] Mounting rod 132, with both ends connected to two fixing plates 131;

[0060] A pressure roller 133 is rotatably mounted on a mounting rod 132. The upper surface of the tube 200 is in contact with the pressure roller 133. The circumferential surface of the pressure roller 133 is set as an inwardly concave arc surface and is used to make contact with the upper surface of the tube 200.

[0061] In other words, the concave arc surface of the pressure roller 133 has the same curvature as the arc support surface of the meniscus 111, and forms a channel that matches the outer diameter of the pipe 200, thereby ensuring that the pipe 200 is always stably conveyed forward along its axial direction, and improving the conveying accuracy of the pipe 200.

[0062] Meanwhile, the setting of the pressure roller 133 ensures that the pipe 200 is always conveyed forward along the meniscus 111, and will not float up under the action of buoyancy, ensuring that the lower half of the pipe 200 can be fully cooled, thereby ensuring the uniform cooling of the entire pipe 200.

[0063] Preferably, the mounting rod 132 is also provided with positioning fasteners 134. The positioning fasteners 134 are located on both sides of the pressure roller 133 and are set close to the pressure roller 133. The setting of the positioning fasteners 134 ensures that the pressure roller 133 is always in the preset position and will not shift left or right, so that the pipe 200 can be smoothly conveyed forward without interference with the pressure roller 133.

[0064] Preferably, the bottom of the housing 100 is provided with a water outlet pipe 140, which is connected to the receiving cavity 101. The spray pipe 122 and the water outlet pipe 140 form a circulating cooling system. Through the circulating cooling system, the cooling water can be used multiple times inside the system, which significantly reduces the demand for fresh water, reduces water waste, and thus reduces water costs.

[0065] Furthermore, the circulating cooling system supports continuous production and automated operation, eliminating the need for frequent replenishment or replacement of cooling water, thus improving cooling efficiency.

The above are specific embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.

[0067] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

Therefore, a feature defined with "" or "a" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
