Description

Technical Field

[0001] This application belongs to the technical field of chemical product storage tanks, and particularly relates to a safe storage tank for chemical products. Background Technology

[0002] All technologies that use chemical methods to change the composition or structure of substances or synthesize new substances belong to chemical production technology, also known as chemical process. The products obtained are called chemicals or chemical products. With the continuous development of the storage tank industry, more and more industries and enterprises are using storage tanks. Steel storage tanks are special equipment for storing various liquid raw materials and finished products.

[0003] The existing utility model with authorization announcement number CN212830427U discloses a chemical product safety storage tank, including an outer shell and an inner storage layer. The inner cavity of the outer shell and the outer end of the inner storage layer are uniformly filled with a heat insulation layer. A liquid inlet is fixedly opened at the top left end of the outer shell, and a liquid inlet valve is fixedly installed inside the liquid inlet.

[0004] The above technical solution can provide a certain degree of protection and fixation for the internal storage layer during transportation, resulting in a high level of safety for the storage tank. It is suitable for transportation and mass production. However, under normal use, the heat insulation layer and multiple springs on the outside of the storage tank occupy a large area, which prevents the use of inflatable airbags to cushion the safety of the storage tank when it is about to tip over. This affects the carrying and transportation of the storage tank, and consequently, its use.

[0005] Therefore, we propose a safe storage tank for chemical products to solve the above problems. Utility Model Content

[0006] The purpose of this application is to solve the problem that the heat insulation layer and multiple sets of springs on the outside of the storage tank occupy a large area in the prior art, and to propose a safe storage tank for chemical products.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A chemical product safety storage tank includes a tank body. Two mounting limiting rings are fixedly connected to the outer surface of the tank body. A buffer airbag is fitted onto the outer surface of the tank body. The two mounting limiting rings have their sides close to each other in contact with the upper and lower surfaces of the buffer airbag, respectively. A connecting pipe is fixedly connected to the outer surface of the buffer airbag. An air pump is fixedly connected to the input end of the connecting pipe. The air pump is fixedly embedded in the outer surface of the tank body. An extension pipe is fixedly connected to the input end of the air pump. The input end of the extension pipe passes through the tank body and extends to the outside of the tank body. An accelerometer sensor is fixedly connected to the upper surface of one of the mounting limiting rings in a circumferentially arranged manner. Each accelerometer sensor is connected to the air pump signal via a PLC controller.

[0009] Preferably, a frustum is fixedly connected to the bottom surface of the tank, and a placement tray is fixedly connected to the bottom surface of the frustum.

[0010] Preferably, a lifting frame is fixedly connected to the upper surface of the tank, and a lifting handle is fixedly connected to the upper surface of the lifting frame.

[0011] Preferably, a T-shaped pipe is fixedly connected to the upper surface of the tank, and a threaded ring is fixedly connected to the output end of the T-shaped pipe.

[0012] Preferably, a control lever is rotatably connected inside the T-shaped tube, and a rotating disk is fixedly connected to the top end of the control lever.

[0013] Preferably, a switch valve is fixedly connected to the outer surface of the tank, and an output pipe is fixedly connected to the output end of the switch valve.

[0014] Preferably, a pressure relief pipe is fixedly connected to the upper surface of the tank, and an air pressure reducing valve is fixedly connected to the outer surface of the pressure relief pipe.

[0015] Preferably, a reinforcing ring is fixedly connected to the outer surface of the connecting tube, and the left side of the reinforcing ring is fixedly connected to the outer surface of the buffer airbag.

[0016] In summary, the technical effects and advantages of this application are as follows: By incorporating a tank body, a buffer airbag, a connecting pipe, an air pump, and an extension pipe, the buffer airbag located outside the tank body, and the power supply of the air pump controlled by the PLC controller, allow air to be easily transported through the extension pipe to the connecting pipe and then to the buffer airbag for expansion. This expansion of the buffer airbag outside the tank body effectively cushions the impact force on the chemical product safety storage tank. Furthermore, by utilizing the installation limit ring and acceleration sensors, multiple acceleration sensors can be fixed in place using the upper installation limit ring. These acceleration sensors can detect the acceleration of the chemical product safety storage tank after tipping over, and the PLC controller can automatically control the air pump to promptly cushion the impact on the chemical product safety storage tank. This not only reduces the footprint of the storage tank but also improves its safety performance, facilitating its transport and use. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4A chemical product safety storage tank includes a tank body 1, a frustum 2 fixedly connected to the bottom surface of the tank body 1, and a placement plate 3 fixedly connected to the bottom surface of the frustum 2. The frustum 2 and the placement plate 3 form a stable support structure, thereby enabling the tank body 1 to be stably supported on a horizontal ground.

[0024] Two mounting limit rings 10 are fixedly connected to the outer surface of the tank body 1. A buffer airbag 12 is fitted on the outer surface of the tank body 1. The two mounting limit rings 10 are close to each other on one side, respectively contacting the upper surface and the bottom surface of the buffer airbag 12. A lifting frame 4 is fixedly connected to the upper surface of the tank body 1. A lifting handle 5 is fixedly connected to the upper surface of the lifting frame 4. By manually holding the lifting handle 5, the tank body 1 can be easily lifted using the lifting frame 4, thus making it easy to pull the tank body 1 to the required position.

[0025] A connecting pipe 14 is fixedly connected to the outer surface of the buffer airbag 12. A reinforcing ring 13 is fixedly connected to the outer surface of the connecting pipe 14. The left side of the reinforcing ring 13 is fixedly connected to the outer surface of the buffer airbag 12. The reinforcing ring 13 is fixed at the connection between the connecting pipe 14 and the buffer airbag 12, thereby improving the connection stability between the connecting pipe 14 and the buffer airbag 12.

[0026] An air pump 15 is fixedly connected to the input end of the connecting pipe 14. The air pump 15 is a device for purging air from or adding air to a closed space. The model of the air pump 15 is YD-371B. The air pump 15 is fixedly embedded in the outer surface of the tank body 1. A T-shaped pipe 6 is fixedly connected to the upper surface of the tank body 1. A threaded ring 7 is fixedly connected to the output end of the T-shaped pipe 6. By manually connecting the pipeline for transporting chemical products from the outside to the threaded ring 7, the chemical products can be conveniently transported into the interior of the tank body 1 through the T-shaped pipe 6.

[0027] The T-tube 6 is internally connected to a control lever 8, and a rotating disk 9 is fixedly connected to the top of the control lever 8. By manually holding the rotating disk 9, the control lever 8 can be rotated inside the T-tube 6, which can easily adjust the flow rate of chemical products transported through the T-tube 6 into the tank 1.

[0028] An extension pipe 16 is fixedly connected to the input end of the air pump 15. The input end of the extension pipe 16 passes through the tank body 1 and extends to the outside of the tank body 1. A switch valve 19 is fixedly connected to the outer surface of the tank body 1. An output pipe 20 is fixedly connected to the output end of the switch valve 19. By manually opening the switch valve 19, the chemical products in the tank body 1 can be conveniently output using the output pipe 20, thus facilitating the use of this safety storage tank to store chemical products.

[0029] One of the mounting limit rings 10 has an accelerometer 11 fixedly connected to its upper surface, which is arranged in a circular pattern at equal intervals. The accelerometer 11 is a test instrument used to convert the physical signal of acceleration into an electrical signal that is easy to measure. The model of the accelerometer 11 is AD-YD83. Each accelerometer 11 is connected to the air pump 15 via a PLC controller. The upper surface of the tank 1 is fixedly connected to a pressure relief pipe 17, and the outer surface of the pressure relief pipe 17 is fixedly connected to an air pressure reducing valve 18. The air pressure reducing valve 18 regulates the flow of the medium by controlling the opening and closing of the valve body, thereby reducing the pressure of the medium. At the same time, it adjusts the opening and closing of the valve body by using the pressure after the valve to keep the pressure after the valve within a certain range. Cooling water is sprayed into the valve body or after the valve to reduce the temperature of the medium. The air pressure reducing valve 18 facilitates the reduction of the high pressure in the tank 1, and allows the gas in the tank 1 to be discharged through the air pressure reducing valve 18, thereby reducing the risk of explosion due to excessive pressure in the tank 1.

[0030] The working principle of this utility model is as follows: In use, firstly, the acceleration sensor 11, air pump 15, and PLC controller are connected to a mobile power source located outside the storage tank. When the safety storage tank is needed for the safe storage and transportation of chemical products, the storage tank is first moved by manually holding the lifting handle 5 and using the lifting frame 4 to pull it. Then, the storage tank is manually placed on a level surface. The support structure formed by the cone 2 fixed under the tank body 1 and the placement plate 3 ensures the storage tank is stably positioned as needed. The external pipeline for transporting chemical products is then manually connected to the installation threaded ring 7. By twisting the rotating disc 9, the control lever 8 can be used to open the T-tube 6 switch to transport the chemical products into the tank body 1, thus facilitating the transport. Chemical products are manually transported into tank 1, and the T-tube 6 is closed by twisting the rotating disc 9. During the transport of the storage tank, it may tip over. Multiple acceleration sensors 11 fixed on the limit ring 10 can detect the acceleration of the tipping of the upper part of the tank 1. When the maximum set acceleration is reached, the PLC controller outside the storage tank will automatically control the air pump 15 to operate at maximum power, so that the extension pipe 16 can draw air into the air pump 15 and deliver it to the buffer airbag 12 through the connecting pipe 14. The buffer airbag 12 can then expand rapidly to form a protective film for the storage tank that is about to tip over, thus buffering the impact force on the storage tank and improving the safety of the storage tank.
