Embodiment 1

[0027] Such as Figure 1-3 As shown, the wood chip drying device of the present invention includes a combustion furnace 1, a blower 2, a dryer tunnel 3 and a dryer trolley 4, the combustion furnace 1 is connected with the blower 2, and the two ends of the dryer tunnel 3 are provided with furnace doors 15. There are two main rails 11 in the dryer tunnel 3, and the dryer trolley 4 is installed on the main rails 11. There are seven heat exchangers 5 on the side of the dryer tunnel 3, and the combustion furnace 1 is connected to each heat exchanger 5 through a heat pipe 6. The upper and lower parts of the heat exchanger 5 are respectively provided with an exhaust fan 7 and a flow fan 8. The exchanger 5 is connected with the dryer tunnel 3 through the flow air channel 14, wherein, seven heat exchangers 5 divide the corresponding dryer tunnel 3 into seven drying units 3.1, and each drying unit 3.1 is parked with 2 dryer trolleys 4. The side of the dryer tunnel 3 is also provided w...

Embodiment 2

[0030] The difference from Embodiment 1 is that the exhaust fan 7 and the flow fan 8 are replaced by a dual-purpose exhaust fan, and the control system 10 controls the dual-purpose exhaust fan according to the temperature in the dryer tunnel 3 . The forward and reverse rotation of the exhaust fan realizes the effect of blowing and sucking air. The rest of the working principles are the same as in Embodiment 1.

Abstract

The invention discloses a wood chip drying device, which comprises a combustion furnace (1), a blower (2), a dryer tunnel (3) and a dryer trolley (4), wherein the combustion furnace (1) is connected with the blower (2); the wood chip drying device is characterized by comprising at least two heat exchangers (5), wherein the combustion furnace (1) is connected with the heat exchangers (5) through a heat pass pipe (6); the upper parts and the lower parts of the heat exchangers (5) are provided with exhaust fans (7) and flow fans (8) respectively; the heat exchangers (5) are connected with the dryer tunnel (3) through air flow passages (14); and the dryer tunnel (3) corresponding to the heat exchangers is divided into drying units (3.1) by the heat exchangers (5). The wood chip drying device has the advantages that the drying tunnel is divided into a plurality of drying units by the heat exchangers to realize a multi-point execution and multi-point air draft mode, and the wood chip drying effect is good.

Description

technical field [0001] The invention relates to a wood drying equipment, in particular to a wood chip drying device. Background technique [0002] At present, in the wood chip drying process, the traditional process is to use the original method of manual turning and drying in the sun, which not only takes up a large area of ​​land and manpower, but also weather factors directly affect the output and quality of wood chip drying. Therefore, people have invented various drying equipment, and existing wood chip dryer all adopts chain mesh bag dryer. However, the existing chain mesh bag wood chip dryer has disadvantages such as complex structure, bulky, high labor intensity, and difficulty in finding operators. At the same time, the existing equipment has low output and high energy consumption, and the temperature is controlled by experience, so it is difficult to guarantee the drying quality. Therefore, this type of dryer is difficult to promote, which requires the development...
