Preferably, a plurality of air return holes are provided on the other side of the partition opposite to the partition provided with air blowing holes in the box.

Preferably, the gas-fired grate furnace is a strip-shaped fire grate furnace.

Preferably, the heat exchanger includes a lower vertical pipe, an upper horizontal pipe and a smoke outlet at the top, and the vertical pipe is fixedly connected with the gas fire grate furnace.

Beneficial effect:

The gas heating and drying device described in the utility model has the following characteristics:

1. In the gas heating and drying device described in the utility model, the fan, the gas fire grate furnace and the heat exchanger are fixed in the same box as the drying chamber, so there is no need for installation during use, which saves space;

2. The partition plates on both sides of the drying chamber in the gas heating and drying device described in the utility model are respectively provided with air blowing holes and return air holes, and part of the hot air is sucked into the heat exchanger by the fan after passing through the return air holes, so that recycling can be realized. Reduce heat loss, high thermal efficiency, low energy consumption.

3. The gas-fired grate furnace described in the utility model adopts a long strip-shaped fire grate furnace, which has the advantages of narrow body shape and small space occupation.

4. The heat exchanger of the utility model includes a lower vertical pipe, an upper horizontal pipe and a smoke outlet on the top. The vertical pipe is fixedly connected with the gas fire grate furnace, and the smoke and hot gas flow along the pipe. The smoke exhaust port flows upward from the inside, and no induced draft fan or exhaust fan is needed for smoke exhaust.

【Detailed ways】

The utility model will be further described below in conjunction with specific embodiments, but the scope of the utility model is not limited thereto.

Example 1

As shown in Figures 1-3, a gas heating and drying device includes a box body 10, a fan 1 on the top of the box body, a heat exchanger 2 fixed on one side of the box body, and a gas burner installed under the heat exchanger 2. The grate furnace 3, the partitions 4 around the inside of the box body 10 form a drying chamber 6, the side partition 4 close to the heat exchanger 2 is provided with blowing holes 5, and the other side partition 4 opposite to it is provided with Air return holes 7, an exhaust port 8 is provided on the top of the drying chamber 6, and an air inlet 9 is provided at the top of the box body 10 close to the air suction port of the fan 1. Wherein, the gas fire grate furnace 3 is a strip fire grate furnace, and the heat exchanger 2 includes a lower vertical pipe 21, an upper horizontal pipe 22 and a smoke outlet 23 on the top, and the vertical pipe 21 It is fixedly connected with the gas fire grate furnace 3 . As shown in Figure 3, the flame burns against the inner wall of the vertical pipe 21, and the smoke and hot gas flow upward along the pipe to the smoke outlet 23. The outside air becomes hot air. Under the action of the fan 1, the air enters the box body 10 through the air inlet 9, and flows in the direction of the arrow in the figure, and generates hot air under the action of the heat exchanger 2, and the hot air is evenly sent in through the blowing holes 5 In the drying chamber 6, the material in the drying chamber 6 is dried, and the moisture formed after the material is heated is discharged through the exhaust port 8 on the top of the drying chamber 6, and part of the hot air is passed through the air return hole 7 on the other side of the drying chamber 6 Go back to the air suction port of the fan 1, and under the action of the fan, it passes through the heat exchanger again and enters the drying chamber 6, so that the materials are evenly dried in such a cycle. At the same time, the blower fan 1 constantly replenishes new air through the air inlet 9 .

The utility model has the advantages of simple structure, reliable operation, low energy consumption and uniform drying, and is especially suitable for drying tea, Chinese medicinal materials and other materials. With the device of temperature controller and time controller, automatic baking can be realized.
