Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, specifically a closed container cooling device. Background Technology

[0002] Sodium hypochlorite decomposes rapidly when exposed to light and heat. To prevent decomposition and gas release, and to reduce the risk of corrosion, sodium hypochlorite needs to be stored in airtight containers. Most existing sodium hypochlorite storage tanks are sealed and stored outdoors. During hot summer months, when the storage temperature exceeds 35°C, sodium hypochlorite will decompose, reducing its concentration and affecting normal use.

[0003] Traditional cooling methods in the industry include: 1. Installing internal cooling pipes and external jacketed pipes in the storage tank and continuously supplying circulating water and chilled water for cooling; 2. Installing spray pipes at the top of the storage tank for continuous cooling. However, existing storage tank cooling methods have the following shortcomings: 1. The method of installing internal cooling pipes and external jacketed pipes in the storage tank has high investment costs, and the operation costs of circulating water and chilled water are also very high. 2. Although the method of installing spray pipes at the top of the storage tank is lower in cost, the cooling area is limited, and the cooling effect on the middle and bottom of the storage tank is very limited, making precise temperature control impossible. Utility Model Content

[0004] This invention addresses the problem that the spray cooling method used in existing closed storage tanks for sodium hypochlorite cannot achieve precise temperature control, leading to an increase in the amount of sodium hypochlorite decomposition and failure. It provides a closed container cooling device that can target the temperature distribution of the closed storage tank, precisely control the overall temperature of the tank, and reduce the decomposition and failure of sodium hypochlorite.

The annular spray pipe is provided with a plurality of nozzles.

[0009] A conveying mechanism is provided, which connects the annular spray pipe of the spraying mechanism to a water source, and the conveying mechanism has at least a first shut-off valve.

[0022] The beneficial effects of this utility model are:

This improves the accuracy of temperature control and solves the problem that the spray cooling method of the existing closed sodium hypochlorite storage tank cannot achieve precise temperature control, resulting in an increase in the amount of sodium hypochlorite decomposition and failure.

[0036] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0037] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0038] Example 1

[0039] Among the existing cooling methods for storage tanks, the method of installing internal cooling pipes and external jacketed pipes in the storage tank has high investment costs, and the operation costs of circulating water and chilled water are also very high. While the method of setting up a spray at the top of the storage tank is cheaper, the cooling area is limited, and the cooling effect on the middle and bottom of the storage tank is very limited, making it impossible to achieve precise temperature control.

[0040] To address the aforementioned problems in the prior art, this embodiment provides a closed-system container cooling device for cooling closed storage tanks of sodium hypochlorite stored outdoors. This device can target the cooling process based on the temperature distribution within the closed storage tank, precisely controlling the overall temperature and reducing the decomposition and degradation of sodium hypochlorite. Please refer to... Figure 1The closed-loop container cooling device mainly includes a spraying mechanism 100, a conveying mechanism 200, a lifting mechanism 300, and a control mechanism 400. In this embodiment, the closed-loop container cooling device is used in the sodium hypochlorite storage tank 500 shown in the figure. In one or more other embodiments, this closed-loop container cooling device can also be used for cooling other closed containers.

[0041] The lifting mechanism 300 is used to adjust the spray cooling coverage height of the spray mechanism 100, so that the closed container cooling equipment of this embodiment can cool different positions of the sodium hypochlorite storage tank 500. Figure 1 As shown, the lifting mechanism 300 mainly includes a first slide rail 310, a second slide rail 320, and a lifting belt 330. The first slide rail 310 and the second slide rail 320 are respectively located on both sides of the sodium hypochlorite storage tank 500, and their track directions are vertical. The lifting belt 330 is located on one side of the first slide rail 310, and its conveying direction is also vertical.

[0042] The spraying mechanism 100 is used to spray cooling liquid onto the outer sidewall of the sodium hypochlorite storage tank 500 for cooling. The spraying mechanism 100 mainly includes an annular spray pipe 110 and several nozzles 120. The annular spray pipe 110 is arranged around the outer sidewall of the sodium hypochlorite storage tank 500. Pulleys 112 are provided on both sides of the annular spray pipe 110, and the pulleys 112 are movably embedded in the first slide rail 310 and the second slide rail 320 on both sides, allowing the annular spray pipe 110 to move vertically up and down. A connecting block 114 is provided on the side of the annular spray pipe 110 near the lifting belt 330, and the connecting block 114 is connected to the lifting belt 330, allowing the lifting belt 330 to move the annular spray pipe 110 along with it when moving up and down. Meanwhile, several nozzles 120 are evenly distributed around the annular spray pipe 110, and the spray direction of the nozzles 120 is directed towards the sidewall of the sodium hypochlorite storage tank 500.

[0043] The conveying mechanism 200 is used to input the cooling liquid required for spraying the spraying mechanism 100. The conveying mechanism 200 mainly includes an inlet pipe 210 and a connecting hose 220. One end of the inlet pipe 210 is connected to an industrial water source, and a first shut-off valve 212, which is a solenoid valve, is installed on the inlet pipe 210. The connecting hose 220 is a metal hose, with one end connected to the inlet pipe 210 and the other end connected to the annular spray pipe 110 of the spraying mechanism 100, thereby inputting the cooling liquid. By setting the connecting hose 220, the influence on the pipeline structure during the up-and-down movement of the spraying mechanism 100 is avoided, allowing the conveying mechanism 200 to flexibly adapt to the movement of the spraying mechanism 100.

[0044] The control mechanism 400 is used to control the unified operation of the lifting mechanism 300, the spraying mechanism 100, and the conveying mechanism 200 according to program logic. The control mechanism 400 mainly includes a PLC controller and a DCS control system. The PLC controller and the DCS control system are connected by signals, and the PLC controller is also connected by signals to the lifting belt 330 of the lifting mechanism 300 and the first shut-off valve 212 of the conveying mechanism 200 for unified operation control.

[0045] One specific working method of this embodiment is as follows:

[0046] When the outdoor temperature is high, the control mechanism 400 is activated; the PLC controller of the control mechanism 400 drives the first shut-off valve 212 to open, thereby connecting the spraying mechanism 100 to the cooling liquid and starting to spray; then, the PLC controller of the control mechanism 400 drives the lifting belt 330 to move up and down, driving the spraying mechanism 100 to move up and down, thereby uniformly cooling the entire sodium hypochlorite storage tank 500; when the outdoor temperature drops, the control mechanism 400 is turned off, stopping the operation of the entire closed container cooling equipment.

[0047] In this embodiment, the closed-loop container cooling device uses a spray mechanism 100 on the outer side wall of the sodium hypochlorite storage tank 500. A continuous cooling liquid is provided by a conveying mechanism 200, and a lifting mechanism 300 drives the spray mechanism 100 to move vertically. This achieves uniform cooling control of the entire sodium hypochlorite storage tank 500, improving the accuracy of temperature control. This solves the problem in the prior art where the spray cooling method for closed-loop sodium hypochlorite storage tanks cannot achieve precise temperature control, leading to an increase in the amount of sodium hypochlorite decomposition and failure.

[0048] Furthermore, in this embodiment, a motor 340 is provided at the lower end of the lifting belt 330 of the lifting mechanism 300. The lifting belt 330 moves up and down by the drive of the motor 340, and the motor 340 is connected to the PLC controller of the control mechanism 400 by signal and controlled by the signal of the control mechanism 400.

[0049] Furthermore, in this embodiment, two nozzles 120 of the spray mechanism 100 are provided at a single point on the circumference of the annular spray pipe 110, and the spraying directions of the two nozzles 120 at the same point have a certain angle, thereby expanding the coverage of the cooling liquid sprayed by the nozzles 120.

[0050] Furthermore, in this embodiment, a drain branch pipe 213 is also provided on the water inlet pipe 210 of the conveying mechanism 200. A second shut-off valve 214 is provided on the drain branch pipe 213. The drain branch pipe 213 is used to discharge the remaining cooling liquid in the pipe after the water inlet pipe 210 has finished working. In addition, a third shut-off valve 216 is also provided between the end of the water inlet pipe 210 connected to the water source and the branch point of the drain branch pipe 213. The third shut-off valve 216 is used for the overall control of the water inlet pipe 210.

[0051] In one or more other embodiments, the lifting belt 330 may also be replaced by other lifting devices such as cylinders.

[0052] Example 2

[0053] Based on the above embodiments, a second embodiment is provided below as a further improvement.

[0054] Please see Figures 2-4 In the second embodiment, the spraying mechanism 100, conveying mechanism 200, lifting mechanism 300 and control mechanism 400 in the first embodiment are improved; at the same time, a detection mechanism is provided.

[0055] like Figure 2 As shown, the detection mechanism is used to detect the temperature at different points on the outer side wall of the sodium hypochlorite storage tank 500. The detection mechanism mainly includes a first temperature sensor 610, a second temperature sensor 620, and a third temperature sensor 630. Specifically, the first temperature sensor 610 is located on the side wall of the sodium hypochlorite storage tank 500, near the bottom; the second temperature sensor 620 is located on the side wall of the sodium hypochlorite storage tank 500, near the middle; and the third temperature sensor 630 is located on the side wall of the sodium hypochlorite storage tank 500, near the top. All three temperature sensors are connected to the PLC controller of the control mechanism 400.

[0056] In the second embodiment, photoelectric signal transmitters 312 are provided at three points on the first slide rail 310 of the lifting mechanism 300, corresponding to the heights of the first temperature sensor 610, the second temperature sensor 620, and the third temperature sensor 630, and the three photoelectric signal transmitters 312 are all connected to the PLC controller of the control mechanism 400.

[0057] In the second embodiment, a reflector 116 is provided on the annular spray pipe 110 of the spray mechanism 100, and on the side close to the first slide rail 310. The reflector 116 can reflect the photoelectric signal of the photoelectric signal transmitter 312.

[0058] One specific working method of this embodiment is as follows:

[0059] When any of the three temperature sensors 610, 620, and 630 of the detection mechanism detects a temperature higher than 34°C at any of the three points in the sodium hypochlorite storage tank 500, the control mechanism 400 controls the first shut-off valve 212 to open, and the spray mechanism 100 begins spraying; it also drives the motor 340 to start, and the photoelectric signal transmitter 312 at the corresponding point on the first slide rail 310 is energized; the spray mechanism 100 begins to spray while moving up and down, and when the spray mechanism 100 moves to the point with the highest temperature... The signal from the photoelectric signal transmitter 312 is reflected by the reflector 116, and the receiving end of the photoelectric signal transmitter 312 receives the photoelectric signal. After receiving the corresponding signal, the control mechanism 400 controls the motor 340 to stop running, and the spray mechanism 100 concentrates on spraying and cooling at this point. When the temperature at all three points is below 33°C, the control mechanism controls the first shut-off valve 212 to close, the corresponding photoelectric signal transmitter 312 on the first slide rail 310 is de-energized, and the motor 340 stops running, and the entire closed container cooling equipment stops operating.

[0060] It should also be noted that when the temperatures at the top, middle, and bottom all exceed 34°C, regardless of where the highest temperature point of the spray is, it will have the best cooling effect on the entire sodium hypochlorite storage tank 500. For example, if the temperature is highest at the bottom, when the device sprays the bottom of the tank, the spray water carries away the heat from the bottom. Since there is a temperature difference between the upper and lower parts of the tank, the heat from the upper part will be transferred to the lower part through heat conduction and carried away by the spray water. If the temperature at the bottom drops below 33°C, but the temperature at the upper and middle parts is still above 34°C, the spray mechanism 100 will automatically move upwards to spray.

[0061] In this embodiment, the closed-loop container cooling device uses three temperature sensors at different heights: a first temperature sensor 610, a second temperature sensor 620, and a third temperature sensor 630. It also has three corresponding photoelectric signal transmitters 312 on the lifting mechanism 300. Furthermore, by utilizing the reflector 116 on the spray mechanism 100 in conjunction with the photoelectric signal transmitters 312, the spray mechanism 100 can adjust its height in real-time to precisely spray different areas of the sodium hypochlorite storage tank 500 during the spraying process. This further improves the spray cooling efficiency and temperature control accuracy of the closed-loop container cooling device in the above embodiment.

[0062] In one or more other embodiments, the photoelectric signal transmitter 312 may also be disposed on the side wall of the sodium hypochlorite storage tank 500 or in other parts of the lifting mechanism 300, and located at three points corresponding to the heights of the first temperature sensor 610, the second temperature sensor 620, and the third temperature sensor 630. Alternatively, in one or more other embodiments, a different number of temperature sensors may be disposed, and a corresponding number of photoelectric signal transmitters 312 may be configured.

[0063] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
