Description

Technical Field

[0001] The utility model relates to the technical field of liquid fuel stoves, in particular to a pressurized gasification device for liquid fuel. Background Art

[0002] When using a stove that uses liquid fuel, it is often necessary to pressurize the liquid fuel to ensure that it has a certain pressure to ensure that the fuel reaches the combustion area of ​​the stove smoothly. Usually, stoves use a fuel tank placed at a higher position or a pumping system added to the fuel delivery channel to increase the fuel pressure.

[0003] According to the utility model patent of patent number CN206540196U, a manual and automatic pressurized fuel tank includes a storage tank with a storage chamber, a fuel inlet and a fuel outlet respectively connected to the storage chamber; the storage tank is provided with a pressure pump, which includes a pump body, a piston and a connecting rod, the inner cavity of the pump body is connected to the storage chamber, one end of the connecting rod is connected to the piston, and the other end is exposed to the pump body, and the connecting rod drives the piston to slide back and forth in the inner cavity of the pump body. In this utility model, the storage tank is filled with liquid fuel and a certain pressure is applied. In the initial stage of use, the liquid fuel is automatically transported under the action of pressure. In the later stage of use, the pressure in the tank decreases, and the user can pressurize it through the pressure pump so that the remaining liquid fuel can be smoothly transported, realizing automatic and manual transportation. The entire use process only requires human labor and does not consume other energy, achieving a green and environmentally friendly effect. Manual pressurization can be operated as needed and can be operated continuously to ensure that all liquid fuel is transported and used.

[0004] Although the above technical solution can complete the function of pressurizing and delivering fuel, this technical solution uses a manual pressure pump to pressurize, which is similar to the principle of an air pump, and there is no sealing component in the storage tank after pressurization to seal and store the air pressure in the storage tank. When the connecting rod of the pressure pump drives the piston to move upward along the pump body, the air pressure in the storage tank will overflow from the gap between the piston and the pump body, thereby causing the pressure in the storage tank to decrease and the pressurization work cannot be achieved. Even if the piston and the pump body are in a sealed state, under this structure, the pressurization work of the storage tank cannot be achieved. Utility Model Content

[0005] The purpose of the utility model is to provide a pressurized gasification device for liquid fuel, which can complete the pressurized delivery of liquid fuel. During pressurization, not only can the magnitude of the pressurization intensity be controlled, but the volume of the corresponding position in the storage tank can also be changed according to the amount of liquid fuel in the storage tank, thereby improving the pressurization and delivery effect of the liquid fuel.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

During this process, the air pressure at the rear end of the inner wall of the storage tank will gradually decrease. When the pressure at the rear end of the inner wall of the storage tank is lower than the preset value of the air pressure sensor, the booster pump will work again, and the fuel pressed out by the air pressure will be blown out with the gas and vaporized to a certain extent, and then the stove will cooperate to facilitate the ignition of the fuel.

[0010] The utility model is further configured as follows: the inner wall of the storage tank is slidably connected with a piston that slides along its length direction, and the outer wall of the piston is provided with a sealing ring that cooperates with it.

[0012] By adopting the above technical solution, the positioning piece can ensure that the piston always remains vertical and in contact with the inner wall of the storage tank during sliding, thereby preventing the piston from tilting in the storage tank.

[0013] The utility model is further configured as follows: the rear end of the bottom of the storage tank is tilted downward and a drain valve connected thereto is provided rearwardly.

[0016] By adopting the above technical solution, the pressure of the fuel and gas flowing out of the liquid conduit can be increased by allowing the gas and fuel to change in volume from large to small, thereby increasing the gasification effect on the liquid fuel.

[0017] The utility model is further configured as follows: slots are provided inwardly along the length direction on both the left and right sides of the outer wall of the storage tank, and each slot is provided with a transparent plate that cooperates with and is sealed therewith.

[0018] By adopting the above technical solution, the position of the piston in the storage tank can be directly observed through the transparent plate, thereby knowing the remaining amount of liquid fuel in the storage tank.

[0020] By adopting the above technical solution, the volume inside the storage tank can be compressed by moving the piston, thereby increasing the air pressure inside the storage tank and accelerating the transportation and gasification of the oil.

[0021] The present invention is further configured as follows: a one-way valve communicating with the outer wall of the storage tank is installed between the first air duct and the second air duct.

[0022] By adopting the above technical solution, it is possible to prevent fuel from flowing back into the first air duct and the second air duct.

[0035] Example, see Figure 1-3 A pressurized gasification device for liquid fuel includes a support frame 1, a booster pump 17 installed on one side of the upper end of the support frame 1, a hollow storage tank 11 is arranged in the support frame 1 from front to back and tilted downward, a notch 31 is opened inward along the length direction on both sides of the outer wall of the storage tank 11, and each notch 31 is installed with a transparent plate 32 that cooperates with it and is sealed with it, a piston 12 that slides along the length direction is slidably connected to the inner wall of the storage tank 11, a sealing ring 13 that cooperates with it is provided on the outer wall of the piston 12, and the outer wall of the piston 12 is provided with a sealing ring 13 that cooperates with it. The edges are provided with multiple positioning pieces 14 that are evenly spaced and in contact with the inner wall of the storage tank 11. A first solenoid valve 15 connected to the outer wall of the storage tank 11 is installed above the front end of the outer wall of the storage tank 11. The front end of the upper end of the outer wall of the storage tank 11 is provided with a liquid inlet hopper 23 that is connected to the outer wall and has a funnel-shaped upper end opening. When the piston 12 is located at the front end of the inner wall of the storage tank 11, the liquid inlet hopper 23 is located behind the piston 12. The open end of the liquid inlet hopper 23 is detachably connected to a sealing cover 24 that is sealed therewith. A second solenoid valve 16 connected thereto is installed behind the upper end of the outer wall of the storage tank 11.

[0036] An air pressure sensor 22 is installed above the rear end of the outer wall of the piston 12, and a two-position three-way reversing valve 18 is installed at the air outlet of the booster pump 17. A first air duct 2 is provided between one end of the two-position three-way reversing valve 18 and the front end of the outer wall of the storage tank 11. A second air duct 21 is provided between the other end of the two-position three-way reversing valve 18 and the rear end of the upper end of the outer wall of the storage tank 11. A one-way valve 19 is provided between the first air duct 2 and the second air duct 21 and the outer wall of the storage tank 11. A liquid outlet 25 is provided inwardly at the lower part of the rear end. A liquid guide hopper 26 is provided at the rear end of the outer wall of the storage tank 11, which is connected to the liquid outlet 25 and is larger at the front and smaller at the rear and is tapered. The rear end of the liquid guide hopper 26 is connected to a control valve 27, and the rear end of the control valve 27 is connected to a liquid guide pipe 28. The rear end of the bottom of the storage tank 11 is inclined downward and is provided with a drain valve 29 connected to it. A control panel 3 is provided on one side of the upper end of the support frame 1. The booster pump 17, the first solenoid valve 15, the second solenoid valve 16, the air pressure sensor 22 and the two-position three-way reversing valve 18 are all electrically connected to the control panel 3.

[0037] Usage: When in use, first move the device to the corresponding position and fix it through the support frame 1, then power on the device, and then operate the control panel 3 to open the first solenoid valve 15, then close the control valve 27 and the second solenoid valve 16, and at the same time close one end of the two-position three-way reversing valve 18 and open the other end, and then let the booster pump 17 work. The gas generated by the booster pump 17 is transported to the rear end of the storage tank 11 through the second air duct 21. At this time, the air pressure in the space between the rear end of the piston 12 and the rear end of the inner wall of the storage tank 11 increases. Since the first solenoid valve 15 is in the open state, the pressure is increased. The air pressure will push the piston 12 forward, and when the piston 12 moves, the sealing ring 13 can ensure the sealing between the piston 12 and the inner wall of the storage tank 11, and the positioning piece 14 can ensure that the piston 12 always remains in a vertical state and does not tilt during the movement. When the piston 12 moves to the front end of the liquid inlet hopper 23, the first solenoid valve 15 is closed, and the booster pump 17 and the two-position three-way reversing valve 18 stop working. Then, the sealing cover 24 is removed, and liquid fuel is added to the storage tank 11 through the liquid inlet hopper 23. Then, the sealing cover 24 is covered, and the liquid guide tube 28 is connected to the corresponding stove.

[0038] When the pressure sensor 22 detects that the air pressure at the rear end of the storage tank 11 is within the set range, the other end of the two-position three-way reversing valve 18 is closed, and the gas supply is stopped. The first air duct 2 continues to deliver gas to increase the pressure. After a period of time, the booster pump 17 and the two-position three-way reversing valve 18 are closed, and the liquid fuel in the storage tank 11 under high pressure will flow into the liquid guide hopper 26 through the liquid outlet 25. Due to the shape of the liquid guide hopper 26, the fuel and gas under high pressure will change from large to small in volume and their pressure will further increase when flowing out along the liquid guide hopper 28, and will cooperate with the stove to achieve the gasification effect of the fuel to a certain extent.

[0039] During this process, the air pressure at the rear end of the inner wall of the storage tank 11 will gradually decrease, and the piston 12 will move backward under the pressure of the front end of the inner wall of the storage tank 11 and push the fuel backward. When the pressure at the rear end of the inner wall of the storage tank 11 is lower than the preset value, the booster pump 17 and the two-position three-way reversing valve 18 will work again to increase the air pressure between the front and rear ends of the inner wall of the storage tank 11. Since the rear end of the inner wall of the storage tank 11 is in a pressure relief state, the gas pressure at the front end of the storage tank 11 is much greater than the gas pressure at its rear end during pressurization, and the one-way valve 19 can To avoid gas backflow, the remaining amount of liquid fuel can be known by observing the position of the piston 12 through the transparent plate 32 on the notch 31 during use. After use, the piston 12 is located at the front end of the storage tank 11, and cleaning liquid is added to the storage tank 11. The booster pump 17 is started, and the storage tank 11 is inflated under the action of the two-position three-way reversing valve 18. The piston 12 is allowed to reciprocate in the storage tank 11 through the cooperation of the first solenoid valve 15 and the second solenoid valve 16 to achieve cleaning. After cleaning is completed, the drain valve 29 is opened to discharge the cleaning liquid.

[0040] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
