Description

Technical Field

[0001] This utility model relates to the field of tank spraying technology, specifically to an automatic tank spraying device. Background Technology

[0002] High-risk storage tanks refer to storage tanks used in chemical production that involve highly toxic, flammable, and explosive chemicals, and contain liquefied gases or highly toxic liquids that pose significant hazards.

[0003] Chinese Utility Model Patent Publication No. CN 221520725 U discloses an automatic sprinkler system for cooling and fire prevention of chemical storage tanks. The system uses a temperature sensor to detect the temperature of the chemical storage tank and transmits the data to an external controller. Once the temperature reaches the preset temperature of the external controller, the controller starts a water pump and opens the solenoid valves on the second diversion inlet pipe and the first diversion outlet pipe. This causes the water inside the storage tank to be sprayed onto the outer wall of the chemical storage tank through a spray nozzle on a ring-shaped guide tube, thereby cooling the chemical storage tank and allowing for the recycling of the sprayed water.

[0004] While the aforementioned device can spray water to cool the storage tank, the existing spray equipment is fixed to the outer surface of the storage tank, which can easily lead to uneven spraying and different cooling effects in different areas of the tank, thus affecting the overall cooling effect of the storage tank. Utility Model Content

[0005] To address the problems mentioned in the background section, this invention provides an automatic spraying device for storage tanks.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic spraying device for a storage tank, comprising a storage tank, a return tank installed on the upper surface of the storage tank, a perforated plate fixed to the inner wall of the return tank, a storage tank body installed on the upper surface of the perforated plate, two lifting frames fixed to the front and back of the inner wall of the return tank respectively, a lifting assembly being provided inside the lifting frame, and a spraying assembly being provided on the lower surface of the inner wall of the storage tank.

[0007] Preferably, the front of the liquid storage tank is connected to one end of the liquid inlet pipe.

[0008] Preferably, the lifting assembly includes a servo motor mounted on the upper surface of the inner wall of the lifting frame. The output shaft of the servo motor is fixedly connected to the top end of the screw, and the bottom end of the screw is rotatably connected to the lower surface of the inner wall of the lifting frame. The outer surface of the screw is threaded with a threaded sleeve, and the opposite sides of the two threaded sleeves are fixedly connected to the front and back sides of the diverter pipe, respectively.

[0009] Preferably, a plurality of nozzles are symmetrically installed on the inner wall of the diversion pipe.

[0010] Preferably, the spray assembly includes a water pump installed on the lower surface of the inner wall of the storage tank, and the discharge end of the water pump is connected to the inlet end of the diversion pipe through a discharge pipe.

[0011] Preferably, a barrier is fixed to the lower surface of the diversion pipe.

[0012] Preferably, a temperature conducting box is installed on the right side of the liquid storage tank, a semiconductor cooling chip is installed on the left side of the inner wall of the temperature conducting box, and a cooling fan is installed on the heat dissipation end of the semiconductor cooling chip.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention uses a water pump to draw water from the storage tank and discharge it into a distribution pipe and a nozzle through a drain pipe. A servo motor drives a screw to rotate, which in turn moves the threaded sleeve and the distribution pipe along the lifting frame. The distribution pipe then moves the nozzle up and down repeatedly to spray and cool the outer surface of the storage tank. This solves the problem of uneven spraying in existing devices, which leads to different cooling effects in different areas of the tank and affects the overall cooling effect.

[0015] This invention partially blocks the splashing of spray water by using a barrier, allowing it to fall through the outer surface of the storage tank into the return tank. Impurities in the water are filtered through a perforated plate inside the return tank, and the filtered water falls back into the storage tank for recycling, thus reducing water waste.

[0027] Specifically, the front of the liquid storage tank 1 is connected to one end of the liquid inlet pipe 7;

[0028] Water is supplied to the storage tank 1 through the inlet pipe 7 to compensate for the use of water in the storage tank 1.

[0029] Specifically, the lifting assembly includes a servo motor 61 mounted on the upper surface of the inner wall of the lifting frame 5. The output shaft of the servo motor 61 is fixedly connected to the top end of the screw 62, and the bottom end of the screw 62 is rotatably connected to the lower surface of the inner wall of the lifting frame 5. The outer surface of the screw 62 is threadedly connected with a threaded sleeve 63, and the opposite sides of the two threaded sleeves 63 are fixedly connected to the front and back sides of the diversion pipe 81, respectively.

[0030] Specifically, a number of nozzles 82 are symmetrically installed on the inner wall of the diversion pipe 81;

[0031] Servo motor 61 drives screw 62 to rotate. The rotation of screw 62 drives threaded sleeve 63 and diverter pipe 81 to move along lifting frame 5. Diverter pipe 81 drives nozzle 82 to move back and forth from top to bottom to spray the outer surface of tank body 4.

[0032] Specifically, the spray assembly includes a water pump 84 installed on the lower surface of the inner wall of the storage tank 1, and the discharge end of the water pump 84 is connected to the inlet end of the diversion pipe 81 through a discharge pipe 83.

[0033] The water pump 84 draws water from the inside of the storage tank 1 and discharges it into the diversion pipe 81 and the nozzle 82 through the drain pipe 83. The nozzle 82 sprays water onto the outer surface of the storage tank body 4 to cool it down.

[0034] Specifically, a baffle 9 is fixed to the lower surface of the diversion pipe 81;

[0035] The enclosure 9 partially blocks the splashing of the sprayed water, allowing it to fall through the outer surface of the storage tank 4 into the return tank 2. The return tank 2 is then filtered by the perforated plate 3 inside, which filters out impurities in the water. The filtered water then falls into the storage tank 1 for recycling, reducing water waste.

[0040] Water pump 84 draws water from inside storage tank 1 and discharges it into diversion pipe 81 and nozzle 82 through drain pipe 83. Servo motor 61 drives screw 62 to rotate. The rotation of screw 62 drives threaded sleeve 63 and diversion pipe 81 to move along lifting frame 5. Diversion pipe 81 drives nozzle 82 to move up and down repeatedly to spray the outer surface of storage tank body 4.

The impurities in the water are filtered by perforated plate 3 inside return tank 2. The filtered water falls into storage tank 1 for recycling, reducing water waste.

[0041] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
