Gas hot stove

technical field

The utility model relates to the technical field of gas stoves, in particular to a gas hot blast stove.

Background technique

In the Chinese invention patent application document with the publication number of 105241059A, a direct-fired hot blast stove is disclosed. A linear flame burner is arranged on the front side of the hot blast stove body, and the rear side of the linear flame burner is connected to an air-cooled structure; The inlet of the linear flame burner is connected to one end of the gas pipeline, and the other end of the gas pipeline is connected to the control system; there is a diversion baffle at the inlet of the linear flame burner, and the surrounding of the diversion baffle is in contact with the hot blast stove. Furnace connection.

The hot blast stove in the above-mentioned public documents has a relatively complicated structure and a large floor area. For small and medium-sized enterprises, the investment cost is high.

Therefore, based on the defects of the above-mentioned existing gas-fired hot-blast stoves, it is necessary to improve the existing gas-fired hot-blast stoves.

Contents of the invention

The purpose of the utility model is to provide a gas hot blast stove aiming at the deficiencies of the prior art. The gas hot blast stove solves the defects of the existing gas stoves such as complex structure and high cost.

In order to achieve the above object, the utility model is achieved through the following technical solutions: a gas hot blast stove, including a body, a combustion chamber is arranged at the inner bottom of the body, the top of the combustion chamber is inclined, and the upper end of the inclined top of the combustion chamber is connected with a heat The air pipe, the hot air pipe is vertically arranged inside the body, one end of the hot air pipe passes through the body to connect to the exhaust port, the other end of the hot air pipe is connected to the upper end of the combustion chamber, one side of the body has an air inlet, and the other end of the body The side has an air outlet.

Specifically, the front side of the main body has an air inlet, the natural gas pipeline is pierced with the air inlet, and the air inlet corresponds to the combustion chamber.

More specifically, an exhaust fan is provided at the outlet end of the hot air pipe.

Further, the hot air pipe is S-shaped, and the main pipe is arranged vertically.

Furthermore, two sets of hot air pipes are arranged inside the body, and the two ends of the two sets of hot air pipes are respectively connected.

The beneficial effect of the utility model lies in that the internal structure is relatively simple, and hot air can be formed by directly burning gas, the cost is low, and it is suitable for use by small and medium-sized enterprises.

Description of drawings

Fig. 1 is a schematic diagram of the internal structure of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

See Fig. 1, the utility model gas hot blast stove comprises: combustion chamber 1, hot blast pipe 2, exhaust port 3, air inlet 4, air outlet 5, exhaust fan 6, buffer zone 7.

The utility model comprises a main body, the inner bottom of the main body is provided with a combustion chamber 1, the top of the combustion chamber 1 is inclined, and the upper end of the inclined top of the combustion chamber 1 is connected with a hot air pipe 2, and the hot air pipe 2 is longitudinally arranged inside the main body. One end of the hot air pipe 2 passes through the body to connect to the exhaust port 3 , and the other end of the hot air pipe 2 is connected to the upper end of the combustion chamber 1 . One side of the main body has an air inlet 4, and the other side of the main body is provided with a buffer zone 7, and the buffer zone 7 is externally connected to the air outlet 5. The buffer zone 7 can slow down the speed of the wind, so that the hot air can prolong the residence time in the main body. The main body is cylindrical, and the central axis is arranged horizontally. The outer bottom of the body can be equipped with a bracket.

The front side of the body of the utility model has an air inlet, and the natural gas pipeline is pierced with the air inlet to send the natural gas into the combustion chamber for combustion. Combustion forms hot air, which enters the hot air pipe upwards and is discharged from the exhaust port 3.

The utility model is provided with exhaust fan 6 at one end of the outlet of hot air pipe 2, and guides hot air to discharge. The hot air coming out of the combustion chamber 1 is exchanged with the cold air coming in from the air inlet 4, the temperature of the hot air drops, and the gas flow is strengthened and guided by the exhaust fan 6.

The top of the combustion chamber 1 is roughly splayed, one side is inclined forward, and the other side is inclined backward. The two inclined surfaces are connected to the hot air pipes 2 respectively, and exhaust fans 6 are arranged at the outlet ends of each group of hot air pipes 2 .

The hot air pipe 2 of the utility model is S-shaped, and the main pipe is vertically arranged.

Two groups of hot air pipes 2 are arranged in the body of the utility model, and the two ends of the two groups of hot air pipes 2 are respectively connected.

The air inlet 4 of the utility model is positioned at the upper end of the body, and is externally connected with an air intake fan. The cold wind is sucked into the body by the air intake fan, and the cold wind can move from top to bottom. The cold wind moves in the body, exchanges heat with the hot wind in the hot air pipe 2, and the cold wind becomes hot wind, which is discharged from the air outlet 5.

The utility model has the advantages of simple overall structure, small occupied space and low cost, and is suitable for small and medium-sized enterprises to put into use.

Certainly, the embodiment described above is only a preferred example of the utility model, and does not limit the scope of implementation of the utility model, so all equivalent changes made according to the structure, features and principles described in the utility model patent scope Or modification, all should be included in the utility model patent scope.
