Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for steel-plastic composite pipe production, specifically a spray cooling device for steel-plastic composite pipe production. Background Technology

[0002] Steel-plastic composite pipes are composite pipes made by coating or winding a plastic layer (such as polyethylene or epoxy resin) onto the inner / outer wall of a steel pipe as the base material. They combine the strength of steel pipes with the corrosion resistance and scale prevention of plastics, and are widely used in water supply, gas supply, and other fields. During production, the steel pipes need to be cooled quickly after high-temperature treatment (such as welding and plastic layer forming), so spray cooling is required: by spraying cooling water onto the pipe surface, the shrinkage rate of the material is controlled, avoiding softening and deformation of the plastic layer at high temperatures or cracking of the steel pipe due to thermal expansion and contraction; at the same time, it stabilizes the structure of the plastic layer, ensuring a tight fit with the steel pipe and improving the composite quality; it can also shorten the cooling time and improve production efficiency. This process is a key step in ensuring accurate pipe dimensions and stable performance. However, most spray cooling systems on the market have the problem of excessive energy consumption. The high operating cost is not conducive to cost reduction and efficiency improvement for enterprises, and there is an urgent need for technological optimization. For the above problems, there may already be technical solutions in the existing technology, but this case aims to provide an alternative or replacement technical solution. Utility Model Content

[0003] To achieve the above objectives, this utility model is implemented through the following technical solution: a spray cooling device for steel-plastic composite pipe production, comprising: a cold water storage tank, an output pipe, an input pipe, and a pair of shut-off solenoid valves, wherein the pair of shut-off solenoid valves are respectively installed on the input pipe and the output pipe, the output pipe is installed on the cold water storage tank, and a modular internal spray cooling structure is installed on the cold water storage tank, wherein the modular internal spray cooling structure comprises: a transfer filter box, a side-mounted cooling water tank, a first pipe, a transfer water pump, a second pipe, an internal transfer layer, several internal spray nozzles, several cooling grids, and a third pipe; The intermediate filter box is installed on the cold water storage tank. The side-mounted cooling water tank is connected to the cold water storage tank. The first pipe is connected to the cold water storage tank and to the intermediate water pump. The intermediate water pump is installed on the side-mounted cooling water tank and to the second pipe. The second pipe is connected to the side-mounted cooling water tank. The intermediate transfer layer inside the tank is installed inside the side-mounted cooling water tank. Several spray nozzles inside the tank are installed on the intermediate transfer layer. Several cooling grids are installed inside the side-mounted cooling water tank and are interconnected by pipes. The third pipe is inserted into the side-mounted cooling water tank and connected to the intermediate transfer layer inside the tank. The intermediate filter box is connected to the third pipe. An inclined heat dissipation component is installed on the cold water storage tank. It should be noted that, as described above, the hot water recovered after spraying through the steel-plastic composite pipe is fed into the intermediate filter box via the input pipe. A pair of shut-off solenoid valves on the output and input pipes are used to shut off the output and input pipes during maintenance or emergencies. The recovered hot water undergoes preliminary filtration by the filter material inside the intermediate filter box, and then is transported through a third pipe to the intermediate transfer layer within the side-mounted cooling water tank. Multiple spray nozzles within the tank then spray the hot water onto multiple cooling grids within the side-mounted cooling water tank. The inclined heat dissipation components cool these cooling grids. For cooling, hot water is sprayed down from the top of the side-mounted cooling water tank, cooled by multiple layers of cooling grids, and then pumped by a transfer pump. It is then transported through a second pipeline to the first pipeline and finally stored in a cold water storage tank. During production, cooling water is extracted from the output pipeline for recycling. An emergency stop button on the cold water storage tank can be used to stop the device in case of emergency. The control panel allows for parameter adjustment and setting. The maintenance port on the side-mounted cooling water tank allows for the removal and maintenance of scale accumulated during long-term operation.

[0004] Preferably, the inclined heat dissipation component includes: an integrated cooling compressor pump, a fourth pipe, a fifth pipe, a heat sink bracket, inclined heat sinks, and a side cooling blower; The integrated cooling compressor pump is installed on the cold water storage tank, and the integrated cooling compressor pump is connected to several cooling grids through pipes. The fourth pipe is connected to the integrated cooling compressor pump and the inclined heat sink. The fifth pipe is connected to the integrated cooling compressor pump and the inclined heat sink. The heat sink bracket is installed on the transfer filter box. The inclined heat sink is installed on the heat sink bracket. The side cooling blower is installed on the transfer filter box. It should be noted that, as described above, the liquid refrigerant is stored in the integrated cooling compressor pump. The pump operates and transports the refrigerant through pipes to multiple cooling grids within the side-mounted cooling water tank. In these grids, the refrigerant exchanges heat with the recycled hot water (absorbing heat from the hot water one by one). The heated refrigerant is then transported through the fifth pipe to the inclined heat sink, which is securely supported by a heat sink bracket. During operation, the side cooling blower is simultaneously activated, blowing air onto the inclined heat sink to accelerate the removal of its dissipated heat and help cool the refrigerant. The cooled refrigerant then flows back to the integrated cooling compressor pump through the fourth pipe. At this point, the refrigerant temperature in the integrated cooling compressor pump decreases, and it is transported again to the multiple cooling grids to participate in the circulation. This process is repeated continuously to achieve heat exchange.

[0005] Preferably, the cold water storage tank is equipped with an emergency stop button; Preferably, the side-mounted cooling water tank is provided with a tank maintenance port; Preferably, the cold water storage tank is equipped with an operation panel; Preferably, the transfer filter box is equipped with water filter media.

Its core advantage lies in significantly improving heat dissipation efficiency while possessing extremely high heat exchange efficiency.

[0013] According to the appendix Figure 1-2It is concluded that the hot water recovered after spraying through the steel-plastic composite pipe is input into the transfer filter box 5 via the input pipe 3. A pair of shut-off solenoid valves 4 on the output pipe 2 and the input pipe 3 are used to shut off the output pipe 2 and the input pipe 3 during maintenance or emergency. The recovered hot water is initially filtered by the filter material in the transfer filter box 5, and then transported to the intermediate transfer layer 10 in the side-mounted cooling water tank 6 through the third pipe 13.

The heated refrigerant is then transported to the inclined heat sink 18 through the fifth pipe 16. The inclined heat sink 18 is securely supported by the heat sink bracket 17. When the inclined heat sink 18 is running, the side cooling blower 19 starts simultaneously, blowing air onto the inclined heat sink 18 to accelerate the removal of the heat it dissipates, helping to cool the refrigerant.
