Description

Technical Field

[0001] The utility model relates to the technical field of pipe cooling equipment, and particularly relates to a pipe cooling device with a water replenishing function. Background Art

[0002] During pipe production, the extruded pipes need to be cooled by a cooling device. In the use of the existing cooling device, in order to reduce the waste of water resources, the cooled water is generally recycled into the water tank, and then pumped out of the water tank by a water pump to continue cooling the pipes. When the cooled water is recycled into the water tank, the temperature of the cooled water is relatively high, resulting in an increase in the temperature of the water in the water tank and poor cooling effect of the pipe cooling device. Content of the Utility Model

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a pipe cooling device with a water replenishing function, which can improve the cooling effect.

[0004] The pipe cooling device with a water replenishing function according to the embodiment of the utility model includes:

[0005] A housing provided with a cooling cavity, the cooling cavity having an opening for a pipe to enter the cooling cavity;

[0006] A spray assembly accommodated in the cooling cavity, the spray assembly being capable of spraying water onto the outer surface of the pipe;

[0007] A water tank provided outside the housing, the water tank having a water storage cavity, the water storage cavity being communicated with the cooling cavity;

[0008] A water replenishing pipe provided in the water tank and communicated with the water storage cavity;

[0009] An outlet pipe, one end of the outlet pipe being communicated with the water storage cavity, and the other end of the outlet pipe being communicated with the spray assembly;

[0010] A water pump assembly provided in the outlet pipe for pumping out the water in the water storage cavity;

[0011] A drain pipe communicated with a portion of the outlet pipe between the spray assembly and the water pump assembly;

[0012] A liquid level float switch provided in the water tank, the liquid level float switch being used for detecting the liquid level height in the water storage cavity;

[0014] The pipe cooling device with a water replenishing function according to an embodiment of the present invention has at least the following beneficial effects:

[0015] When the pipe cooling device works, the water pump assembly is started. The water pump assembly pumps the water in the water tank out to the spraying assembly through the water outlet pipe. The spraying assembly sprays water onto the pipe to cool the pipe in the cooling cavity. After that, the water in the cooling cavity flows back to the water storage cavity. Since the temperature of the water in the cooling cavity is higher than that in the water storage cavity, the temperature of the water in the water storage cavity gradually rises. When the temperature of the water in the water storage cavity rises to a certain level, the drain pipe and the water replenishing pipe are opened. While discharging the water in the water storage cavity, water with a lower temperature is replenished into the water storage cavity to lower the temperature of the water in the water storage cavity. When the water level in the water storage cavity is too high, the liquid level float switch sends a first electrical signal to the first solenoid valve to close the water replenishing pipe. When the liquid level in the water storage cavity is too low, the liquid level float switch sends a second electrical signal to the second solenoid valve to open the water replenishing pipe, which can replenish water for the water replenishing cavity in time. On the one hand, it can automatically replenish water for the water tank.

[0041] Refer to Figures 1 to 5 Figures 1 to 5 , the pipe cooling device with a water replenishing function according to an embodiment of the present utility model includes a housing 100, a spraying assembly 200, a water tank 300, a water replenishing pipe 400, a water outlet pipe 500, a water pump assembly 600, a drain pipe 700, a liquid level float switch 800, and a first solenoid valve 910. The housing 100 is provided with a cooling cavity 110, the cooling cavity 110 has an opening 120, and the opening 120 is used for allowing a pipe to enter the cooling cavity 110. The spraying assembly 200 is accommodated in the cooling cavity 110, and the spraying assembly 200 can spray water onto the outer surface of the pipe. The water tank 300 is arranged outside the housing 100, the water tank 300 is provided with a water storage cavity 310, the water storage cavity 310 is communicated with the cooling cavity 110, the water replenishing pipe 400 is arranged on the water tank 300 and communicated with the water storage cavity 310, one end of the water outlet pipe 500 is communicated with the water storage cavity 310, and the other end of the water outlet pipe 500 is communicated with the spraying assembly 200. The water pump assembly 600 is arranged on the water outlet pipe 500 to pump out the water in the water storage cavity 310. The drain pipe 700 is communicated with a part of the water outlet pipe 500 between the spraying assembly 200 and the water pump assembly 600. The liquid level float switch 800 is arranged on the water tank 300, and the liquid level float switch 800 is used for detecting the liquid level height in the water storage cavity 310. The first solenoid valve 910 is arranged on the water replenishing pipe 400 and electrically connected to the liquid level float switch 800. The first solenoid valve 910 is used for controlling the on-off of the water replenishing pipe 400. Thus, by setting the liquid level float switch 800 and the first solenoid valve 910, on the one hand, the water tank 300 can be automatically replenished with water, and on the other hand, the water in the water tank 300 can be replaced in time to avoid the situation that the water temperature in the water tank 300 is too high, resulting in the spraying assembly 200 being unable to effectively cool the pipe, and the cooling effect of the pipe cooling device can be improved.

[0042] Specifically, when the pipe cooling device is working, the water pump assembly 600 is started. The water pump assembly 600 pumps the water in the water tank 300 to the spraying assembly 200 through the water outlet pipe 500. The spraying assembly 200 sprays water onto the pipes to cool the pipes in the cooling cavity 110. After that, the water in the cooling cavity 110 flows back into the water storage cavity 310. Since the temperature of the water in the cooling cavity 110 is higher than that in the water storage cavity 310, the temperature of the water in the water storage cavity 310 gradually rises. When the temperature of the water in the water storage cavity 310 rises to a certain level, the drain pipe 700 and the water replenishing pipe 400 are opened. While discharging the water in the water storage cavity 310, cooler water is replenished into the water storage cavity 310 to lower the temperature of the water in the water storage cavity 310. When the water level in the water storage cavity 310 is too high, the liquid level float switch 800 sends a first electric signal to the first electromagnetic valve 910 to close the water replenishing pipe 400. When the liquid level in the water storage cavity 310 is too low, the liquid level float switch 800 sends a second electric signal to the second electromagnetic valve to open the water replenishing pipe 400, which can replenish water to the water replenishing cavity in time. On the one hand, it can automatically replenish water to the water tank 300. On the other hand, it can change the water in the water tank 300 in time to avoid the situation that the water in the water tank 300 is too hot, resulting in the spraying assembly 200 being unable to effectively cool the pipes, and can improve the cooling effect of the pipe cooling device.

[0043] It should be noted that one of the first electric signal and the second electric signal is a low-level signal, and the other is a high-level signal, which will not be elaborated here.

[0044] It should be noted that by setting the liquid level float switch 800, the water level height in the water storage cavity 310 can be adjusted, and the liquid level float switch 800 will not be blocked, which can reduce the maintenance frequency of the pipe cooling device, and will not be elaborated here.

[0045] Refer to Figure 3 、 Figure 5 In some embodiments of the present utility model, a temperature detection component 920 is further included. The temperature detection component 920 is arranged in the water tank 300 and is electrically connected to the first electromagnetic valve 910. The temperature detection component 920 is used to detect the temperature of the water in the water tank 300, can monitor the temperature of the water in the water storage cavity 310 in real time, and can replace the water in the water storage cavity 310 in time to ensure the cooling effect of the pipe cooling device.

[0046] Specifically, when the temperature of the water in the water storage cavity 310 is too high, the temperature detection component 920 sends a third electric signal to the first electromagnetic valve 910 to make the first electromagnetic valve 910 open the water replenishing pipe 400 and at the same time open the drain pipe 700 to replenish water and change water for the water storage cavity 310, and can replace the water in the water storage cavity 310 in time to ensure the cooling effect of the pipe cooling device.

[0047] It should be noted that the third electrical signal can be a low-level signal or a high-level signal, which will not be elaborated here.

[0048] It should be noted that the temperature detection component 920 can be a thermocouple temperature sensor or a thermistor temperature sensor, which will not be elaborated here.

[0049] Referring to Figure 3 , in some embodiments of the present invention, the liquid level float switch 800 is configured as a double-float liquid level switch. The liquid level float switch 800 includes a connecting rod 810, an upper float 820, and a lower float 830. The connecting rod 810 is connected to the water tank 300. The upper float 820 and the lower float 830 are movably sleeved on the connecting rod 810. The upper float 820 is provided with a first magnet, and the lower float 830 is provided with a second magnet. A first magnetic reed switch is provided near the upper float 820 on the connecting rod 810. The first magnetic reed switch is electrically connected to the first solenoid valve 910. The first magnet is used to trigger the first magnetic reed switch. A second magnetic reed switch is provided near the lower float 830 on the connecting rod 810. The second magnetic reed switch is electrically connected to the water pump assembly 600. The second magnet is used to trigger the second magnetic reed switch, which can improve the use reliability of the pipe cooling device.

[0050] Specifically, when the upper float 820 is located above the lower float 830, when the upper float 820 floats, the first magnet triggers the first magnetic reed switch, so that the first solenoid valve 910 is closed, the water supply pipe 400 is closed, and the water supply in the water storage cavity 310 stops. When the lower float 830 sinks, the water level in the water storage cavity 310 is too low, and the second magnet triggers the second magnetic reed switch, so that the water pump assembly 600 stops working, the water outlet pipe 500 stops discharging water, and the water inlet of the water storage cavity 310 stops. It can prompt the operator to open the water supply pipe 400 to replenish water in time, and can improve the use reliability of the pipe cooling device.

[0051] It should be noted that the liquid level float switch 800 can also be a single-float liquid level float switch 800, which will not be elaborated here.

[0052] In some embodiments of the present invention, the water tank 300 is located below the housing 100, so that the water in the cooling cavity 110 can automatically flow into the water storage cavity 310 under the action of its own gravity without setting a power mechanism, which can reduce the production and manufacturing cost of the pipe cooling device.

[0053] Referring to Figure 3 , Figure 5, in some embodiments of the present utility model, the water tank 300 includes a first main body 301 and a second main body 302. A water storage cavity 310 is provided in the first main body 301. The second main body 302 is provided with an installation cavity 3021 communicating with the water storage cavity 310. The second main body 302 is connected to the first main body 301 and is located outside the water storage cavity 310. The liquid level float switch 800 is accommodated in the installation cavity 3021. When the liquid level float switch 800 fails, it is convenient to maintain the liquid level float switch 800 outside the water storage cavity 310, so as to reduce the maintenance difficulty of the pipe cooling device, and thus reduce the maintenance cost of the pipe cooling device.

[0054] Specifically, the second main body 302 can be connected to the first main body 301 by bolting or welding. Since the second main body 302 is located outside the first main body 301, when the liquid level float switch 800 fails, maintenance personnel do not need to enter the water storage cavity 310. Maintenance personnel can perform inspection and maintenance on the liquid level float switch 800 outside the water storage cavity 310, which can reduce the maintenance difficulty of the pipe cooling device, and thus reduce the maintenance cost of the pipe cooling device.

[0055] Refer to Figure 1 , in some embodiments of the present utility model, the water tank 300 further includes a seal 940 and a cover 950. The installation cavity 3021 has a notch. The seal 940 is covered on the notch, and the seal 940 is clamped between the cover 950 and the second main body 302. The cover 950 is detachably connected to the second main body 302 by a fastener, which can not only improve the sealing performance of the installation cavity 3021, but also facilitate the maintenance of the liquid level float switch 800.

[0056] Specifically, the seal 940 is made of rubber or silica gel and other materials. When sealing the installation cavity 3021, cover the seal 940 on the notch, and press the cover 950 against the seal 940. Then, lock the cover 950 and the seal 940 with a fastener to seal the notch, which can improve the sealing performance of the installation cavity 3021. When the liquid level float switch 800 fails, maintenance personnel can loosen the fastener to disassemble the cover 950 and the seal 940, thereby opening the notch. Maintenance personnel can maintain the liquid level float switch 800 through the notch, which can not only improve the sealing performance of the installation cavity 3021, but also facilitate the maintenance of the liquid level float switch 800.

[0057] It should be noted that the fastener is a bolt or a screw and other components, and there is no limitation here.

[0058] Refer to Figure 6 、 Figure 7, in some embodiments of the present utility model, the water outlet pipe 500 includes a first pipe section 510 and a second pipe section 520 arranged in parallel. The first pipe section 510 is provided with a first control valve 530 for controlling the on-off of the first pipe section 510, and the second pipe section 520 is provided with a second control valve 540 for controlling the on-off of the second pipe section 520. When a failure occurs in the first pipe section 510 or the second pipe section 520, the pipe cooling device can continue to cool the pipe without stopping, which can improve the working efficiency of the pipe cooling device.

[0059] Specifically, when the pipe cooling device is working normally, the first control valve 530 is opened and the second control valve 540 is closed, that is, water flows out from the first pipe section 510 and no water flows out from the second pipe section 520. When a failure occurs in the first pipe section 510, the operator can close the first control valve 530 and open the second control valve 540, so that no water flows out from the first pipe section 510 and water flows out from the second pipe section 520. While the maintenance staff is maintaining the first pipe section 510, the pipe cooling device can continue to cool the pipe without stopping, which can improve the working efficiency of the pipe cooling device.

[0060] Similarly, when a failure occurs in the second pipe section 520, the operator can open the first control valve 530 and close the second control valve 540, that is, water flows out from the first pipe section 510 and no water flows out from the second pipe section 520. While the maintenance staff is maintaining the second pipe section 520, the pipe cooling device can continue to cool the pipe without stopping, which can improve the working efficiency of the pipe cooling device.

[0061] Refer to Figure 8 , in some embodiments of the present utility model, the spraying assembly 200 includes a spraying ring 210 which is communicated with the water outlet pipe 500. A plurality of first nozzles 211 are arranged on the inner wall of the spraying ring 210 at intervals along the circumferential direction of the spraying ring 210. The spraying ends of the first nozzles 211 face the axis of the spraying ring 210, which can improve the cooling effect of the pipe cooling device.

[0062] Specifically, the water flowing out from the water outlet pipe 500 is sprayed out from the first nozzles 211 through the spraying ring 210. By providing a plurality of first nozzles 211, the first nozzles 211 can convert the water flow into refined water droplets, so that the water can fully contact the surface of the pipe, which can improve the cooling effect of the pipe cooling device.

[0063] It should be noted that the inside of the spraying ring 210 is hollow to form a water inlet channel which has a water inlet hole 213. The water inlet channel is communicated with the water outlet pipe 500 through the water inlet hole 213, which will not be elaborated here.

[0064] It should be noted that a plurality of third nozzles 212 are further provided on the inner wall of the spray ring 210. The plurality of third nozzles 212 are arranged at intervals along the circumferential direction of the spray ring 210. The spraying end of the third nozzle 212 faces the axis of the spray ring 210. Along the axial direction of the spray ring 210, the first nozzle 211 and the third nozzle 212 are arranged at intervals, and the third nozzle 212 is located between two adjacent first nozzles 211, which can cool the pipe evenly to ensure the quality of the pipe.

[0065] In some embodiments of the present utility model, the spray assembly 200 further includes a plurality of spray pipes 220. The plurality of spray pipes 220 are arranged at intervals along the circumferential direction of the spray ring 210. One end of the spray pipe 220 is communicated with the spray ring 210, and the length direction of the spray pipe 220 extends along the axis of the spray ring 210. The spray pipe 220 is provided with a plurality of second nozzles. The plurality of second nozzles are arranged at intervals along the length direction of the spray pipe 220, which can improve the cooling effect of the pipe cooling device.

[0066] Specifically, the water flowing out of the water outlet pipe 500 flows through the spray ring 210 to the spray pipe 220, and then sprays out from the second nozzle. By providing a plurality of second nozzles, the second nozzle can convert the water flow into refined water droplets, so that the water can fully contact the surface of the pipe. When the pipe enters the cooling chamber 110 through the opening 120, the pipe is first cooled by the water sprayed out by the first nozzle 211, and then, the pipe is cooled by the water sprayed out by the second nozzle, which can improve the cooling effect of the pipe cooling device.

[0067] It should be noted that the first nozzle 211, the second nozzle and the third nozzle 212 may be well-known technologies and will not be described in detail here.

[0068] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0069] The above has described this embodiment in detail with reference to the drawings, but the present utility model is not limited to the above embodiment. Within the scope of knowledge possessed by those of ordinary skill in the art in the technical field, various changes can be made without departing from the purpose of the present utility model.
