Description

Technical Field

[0001] The present invention relates to the technical field of propane storage tanks, and particularly to a propane storage tank with a pressurizing structure. Background Art

[0002] Propane is an organic compound, a colorless and odorless gas, slightly soluble in water, soluble in ethanol and ether, with stable chemical properties and not prone to chemical reactions. It is commonly used as a refrigerant, an internal combustion engine fuel or a raw material for organic synthesis. Propane has simple asphyxiation and anesthetic effects. A person's brief exposure to propane at a concentration of 1% does not cause abnormal symptoms; exposure to propane at a concentration of less than 10% only causes mild dizziness; when exposed to a high concentration of propane, an anesthetic state and loss of consciousness may occur; when exposed to an extremely high concentration of propane, asphyxiation may result. In case of acute poisoning, symptoms such as dizziness, headache, excitement or drowsiness, nausea, vomiting, and slow pulse may occur; in severe cases, a person may suddenly fall down, have urinary incontinence, loss of consciousness, and even respiratory arrest, and skin frostbite may be caused. Long-term exposure to low concentrations of propane may cause symptoms such as headache, dizziness, poor sleep, easy fatigue, emotional instability, and autonomic nervous system disorders. During the transportation and storage of propane, propane storage tanks are needed for the storage and transportation of propane.

[0003] A Chinese patent discloses a propane storage tank (authorization publication number CN 221665837 U). The patented technology includes a tank body, a protection mechanism is arranged on the outer wall of the tank body, and a gas transmission pipe is arranged at the top of the tank body. A connecting pipe is connected to the end of the gas transmission pipe. An annular cover is sleeved on the outer walls of the ends of the gas transmission pipe and the connecting pipe. First sealing rings that fit and slide on the outer walls of the ends of the gas transmission pipe and the connecting pipe are respectively arranged at the top and bottom of the annular cover. A detection and adsorption mechanism is connected to one outer wall of the annular cover. The present invention detects propane leakage at the connection between the gas transmission pipe and the connecting pipe through the detection and adsorption mechanism and absorbs propane gas with more leakage, and cushions the tank body during transportation to avoid safety accidents caused by the collision of the tank body.

[0004] However, during the use of the above propane storage tank, when it is moved and carried, it is not easy to use a forklift for auxiliary handling, and it is not easy to quickly load and unload after handling. At the same time, when the storage tank is in use, it is necessary to maintain the pressure stability inside the storage tank. During storage and transportation, it is very important to keep the pressure inside the storage tank stable. The storage tank can be pressurized by filling a certain pressure of gas into the storage tank to maintain the normal pressure and stability of the storage tank. However, the outer side of the connecting pipe for corresponding stamping lacks reinforcement and is prone to deformation, which affects the use stability and service life. Therefore, those skilled in the art have provided a propane storage tank with a pressurizing structure to solve the problems raised in the above background art. Summary of the Invention

A connecting mounting column 77 is fitted and installed at the end of the second transmission frame 76 away from the first transmission frame 75. A first sector gear 78 is fixed to the outer side of the connecting mounting column 77. The outer side of the first sector gear 78 is engaged with a second sector gear 79. The second sector gear 79 and the cast iron support frame 73 are rotatably connected through a rotating shaft. The first sector gear 78 and the cast iron support frame 73 are rotatably connected through a rotating shaft. A second reinforcement frame 711 is fixed to one end of the second sector gear 79.

Arc-shaped grooves are formed on the outer sides of the first reinforcement frame 710 and the first reinforcement frame 710, and the sizes of the arc-shaped grooves are adapted to the size of the pressure application pipeline 4. When the device needs to apply pressure, the pressure application mechanism main body 6 can fill gases such as nitrogen into the propane storage tank main body 1 through a compressor inside the propane storage tank main body 1 to achieve the purpose of maintaining the internal pressure and stability, and can maintain the pressure stability in the storage tank. At the same time, when the pressure application pipeline 4 is connected to the propane storage tank main body 1, the support cast iron block 72 is fixed to the outer side of the fixed bracket 2, and the fixed mounting pad 71 is fixed to the top of the support cast iron block 72.

[0033] The working principle of the present invention is as follows: The device is provided with a stable connection device 3. When the propane storage tank main body 1 is moved and carried, the support connection block 5 at the bottom of the fixed bracket 2 is inserted and installed in the support cast iron frame 31. An assembly positioning block 36 is fixed on the outer side of the fixed bracket 2. One side of the assembly positioning block 36 penetrates through the shielding limit pad 34. At this time, the connecting half-threaded rod 37 on the outer side of the assembly positioning block 36 also penetrates through the shielding limit pad 34. The corresponding surface of the connecting half-threaded rod 37 is in contact with the corresponding surface of the cast iron half-threaded rod 38. At this time, the fitting part of the connecting half-threaded rod 37 and the cast iron half-threaded rod 38 forms a complete threaded rod. Then, the cast iron thread sleeve 310 can be rotated, and through the threaded connection between the cast iron thread sleeve 310 and the connecting half-threaded rod 37 and the cast iron half-threaded rod 38, the fixed connection between the assembly positioning block 36 and the shielding limit pad 34 can be conveniently completed. One side of the fixed bracket 2 is now below the support mounting pad 311. The moving frame 314 is vertically pulled by the tension spring 313 in the support mounting housing 312, so that the moving frame 314 drives the reinforcement rod 315 to move, and the lower bottom surface of the reinforcement pad 316 at the bottom of the reinforcement rod 315 is in contact with the upper top surface of the fixed bracket 2, ensuring that the connection between the propane storage tank main body 1, the fixed bracket 2 and the support cast iron frame 31 is stable and does not loosen. When moving and carrying, the forklift forks can be inserted into the corresponding auxiliary connection groove 33 of the fixed mounting seat 32. Therefore, this device is easy to use a forklift for auxiliary handling, and is easy to quickly load and unload after handling. At the same time, the connection structure of the propane storage tank main body 1 is stable and does not loosen during the handling and loading / unloading process, and the safety performance is relatively high; The device is provided with a pressure stabilization device 7. When the device needs to be pressurized, the pressurizing mechanism main body 6 can fill gases such as nitrogen into the tank through a compressor inside the propane storage tank main body 1 to achieve the purpose of maintaining the internal pressure and stability, and can maintain the stability of the pressure inside the storage tank. At the same time, when the pressurizing pipeline 4 is connected to the propane storage tank main body 1, a support cast iron block 72 is fixed on the outer side of the fixed bracket 2, and a fixed mounting pad 71 is fixed on the top of the support cast iron block 72. The fixed mounting pad 71 ensures the stable support of the cast iron support frame 73. The DC servo motor 74 outside the cast iron support frame 73 can be started, and the output shaft of the DC servo motor 74 drives the first transmission frame 75 to rotate. When the first transmission frame 75 rotates, it can drive one end of the second transmission frame 76 at its end to move, so that the other end of the second transmission frame 76 drives the connection mounting column 77 to rotate, and drives the first sector gear 78 to rotate through the connection mounting column 77.
