Description

Technical Field

[0001] This utility model relates to a heating device, specifically a pneumatic heater. Background Technology

[0002] Heaters can be used to heat various components to facilitate production and processing. One type of heater uses a flame generated by burning fuel oil to heat the components. This type of heater mainly includes a fuel supply assembly, a gas supply assembly, an atomizing assembly, an ignition assembly, and a heating head assembly. During operation, the required fuel is pumped from the fuel tank into the atomizer via a fuel pump. Then, high-pressure gas is introduced into the atomizer through the gas supply assembly, atomizing the fuel before it is sprayed into the heating head assembly. The ignition assembly then ignites the atomized fuel to generate a flame that heats the components. The drawbacks of this structure are: it requires two separate driving components, a fuel pump and a gas pump, to supply fuel and high-pressure gas respectively, making the structure relatively complex. Furthermore, after the fuel is pumped into the atomizer, the high-pressure gas often fails to atomize all the fuel, resulting in poor atomization and fuel waste. Additionally, the flame after ignition is relatively small, leading to relatively poor heating efficiency. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a pneumatic heater for solving the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A pneumatic heater includes an oil tank mounted on a frame, characterized in that: the outlet of the oil tank is connected to an oil box, the oil box is connected to a first solenoid valve via a first oil pipe, the first solenoid valve is connected to one end of an oil outlet pipe via a second oil pipe, and the heater also includes an air pump, the air pump is connected to one end of a first air pipe via a second solenoid valve, the other end of the first air pipe is connected to an air outlet pipe, the other end of the oil outlet pipe is connected to an outlet end near the air outlet pipe, high-speed gas in the air outlet pipe can draw fuel in the oil outlet pipe into the air outlet pipe, and eject it from the outlet end of the air outlet pipe along with the high-speed gas, the outlet end of the air outlet pipe extends into the cavity of a heating head, the heating head has through holes communicating with the cavity, and an ignition assembly is provided corresponding to the heating head.

[0006] There are two first solenoid valves on the left and two second solenoid valves on the left and two second solenoid valves on the right. The air pump is connected to one of the second solenoid valves, and the two second solenoid valves are interconnected through a diversion airway assembly.

[0007] It also includes a speed control switch and a start / stop switch. The speed control switch can control the flow rate of the second solenoid valve, and the start / stop switch can control the on / off state of the air pump.

[0008] The ignition assembly includes an igniter body that is mounted on the gas outlet pipe, and the ignition head of the igniter body extends into the heating head.

[0009] The fuel tank has an external fuel metering pipe that communicates with the fuel tank. The fuel metering pipe is vertically arranged, with one end connected to the top of the fuel tank and the other end connected to the bottom of the fuel tank.

[0010] The other end of the oil outlet pipe has a plug that communicates with its inner cavity, and one side of the plug is connected to the inner cavity of the air outlet pipe through a connecting part.

[0011] The heating head has a flat partition that divides the interior of the heating head into a first inner cavity and a second inner cavity. Both sides of the heating head are provided with through holes that communicate with the first inner cavity or the second inner cavity.

[0012] The aforementioned air-pumped heater requires only a single air pump as a power source to supply high-pressure gas and fuel, eliminating the need for an oil pump and atomizer. This simplifies its structure and enables energy-efficient production. By connecting the outlet pipe to the outlet pipe, the low pressure generated by the high-speed gas draws fuel from the oil pipe into the blowing pipe. This allows the required amount of fuel to be directly atomized by the high-speed gas and sprayed from the outlet pipe into the heating head, effectively improving fuel atomization and preventing fuel waste. This also ensures more complete and thorough combustion of the subsequent flame, thus enhancing heating quality. Attached Figure Description

[0018] As shown in the figure, the present invention discloses an air-driven heater, including an oil tank 1 mounted on a frame. The outlet of the oil tank 1 is connected to an oil box 2. The oil box 2 is connected to a first solenoid valve 4 via a first oil pipe 3. The first solenoid valve 4 is connected to one end of an oil outlet pipe 15 via a second oil pipe 12. The present invention also includes an air pump 9, which is connected to one end of a first air pipe 11 via a second solenoid valve 5. The other end of the first air pipe 11 is connected to an air outlet pipe 14. The other end of the oil outlet pipe 15 is connected to the outlet end near the air outlet pipe 14. Specifically, the other end of the oil outlet pipe 15 has a plug 22 communicating with its inner cavity. One side of the plug 22 is connected to the inner cavity of the air outlet pipe 14 via a connecting part 23. The high-speed gas in the exhaust pipe 14 can draw the fuel in the fuel outlet pipe 15 into the exhaust pipe 14, and then eject it from the outlet end of the exhaust pipe 14 along with the high-speed gas. The outlet end of the exhaust pipe 14 extends into the cavity of the heating head 17. The heating head 17 has through holes 18 arranged on it, communicating with the cavity. An ignition assembly is provided on the heating head 17. A sleeve part 16 is integrally provided on the heating head 17. A clamping part can be provided on the sleeve part to facilitate the installation and connection of the exhaust pipe 14, the fuel outlet pipe 15 and the sleeve part 16. There are two first solenoid valves 4 on the left and two second solenoid valves 5 on the right. The air pump 9 is connected to one of the second solenoid valves 5. The two second solenoid valves 5 are interconnected through the split air passage group 6, so that a single air pump 9 can supply air to both second solenoid valves 5. By setting two sets of first and second solenoid valves, two heating heads 17 can be set up, which can facilitate the simultaneous heating of different components. It also includes a speed control switch 7 and a start / stop switch 8. The speed control switch 7 controls the flow rate of the second solenoid valve 7, thereby adjusting the flame size. The start / stop switch 8 controls the on / off state of the air pump 9. The ignition assembly includes an igniter body 13 mounted on the exhaust pipe 14, with the ignition head of the igniter body 13 extending into the heating head 17. The fuel tank 1 has a fuel metering pipe 10 connected to it. The fuel metering pipe 10 is vertically arranged, with one end connected to the top of the fuel tank 1 and the other end connected to the bottom of the fuel tank 1. By observing the fuel level in the fuel metering pipe 10, the amount of fuel in the fuel tank 1 can be determined. The heating head 17 has a flat partition 20 that divides the interior of the heating head 17 into a first inner cavity 19 and a second inner cavity 21. Both sides of the heating head 17 have through holes 18 that communicate with either the first inner cavity 19 or the second inner cavity 21, enabling synchronous combustion heating on both sides of the heating head 17.

[0019] The working principle of this utility model is as follows: the oil box 2 and the first solenoid valve 4 are opened, allowing the fuel in the oil tank 1 to flow into the oil outlet pipe 15 through the second oil pipe 12. The heating head 17 is placed in the heating position (the height of the heating position is lower than the height of the oil tank 1 to ensure that the fuel can enter the oil outlet pipe 15). At this time, the air pump 9 is working and controls the second solenoid valve 5 to open appropriately. High-speed gas enters the air outlet pipe 14, and the high-speed gas passing through the air outlet pipe 14 will generate negative pressure. The fuel at the outlet end of the oil outlet pipe 14 will be attracted by the negative pressure and enter the air outlet pipe 14 through the sealing head 22 and the connecting part 23. At this time, the high-speed gas will blow away the fuel and atomize it, and blow it into the heating head 17. The ignition component will ignite the atomized fuel, causing combustion to occur in the entire heating head 17. The flame or hot gas will burst out from the through hole 18, thereby burning and heating the components.

[0020] This invention's structure requires only a single air pump as a power source to supply high-pressure gas and fuel, eliminating the need for an oil pump and atomizer. This simplifies the structure and enables energy-efficient production. By connecting the outlet pipe to the outlet pipe, the low pressure generated by the high-speed gas draws fuel from the outlet pipe into the blowing pipe. This allows the required amount of fuel to be directly atomized by the high-speed gas and sprayed from the outlet pipe into the heating head, effectively improving fuel atomization and preventing fuel waste. This also ensures more complete and thorough combustion of the subsequent flame, enhancing heating quality.
