Description
Technical Field
[0001] The utility model belongs to the technical field of bamboo board processing equipment, and particularly relates to a hot air drying device for bamboo boards. Background Technique
[0002] China is a big bamboo country with a large bamboo output and a long history of bamboo utilization. Bamboo products are rich. Bamboo has the advantages of good toughness and high strength and is used as raw materials for indoor floors, outdoor floors, furniture, etc. in the market. Bamboo boards can be formed by bonding and hot pressing between bamboo slices. Before the bamboo raft is hot pressed and formed, it is necessary to dry the bonded bamboo board to reduce its moisture content.
[0003] At present, most bamboo boards are dried by a dryer, and the bamboo boards are continuously dried in an environment of 60-70 degrees. When the ventilation is good, a better drying effect can be achieved. However, the ventilation structure inside the existing dryer is installed at a fixed position, and most of the blowing angles are straight up and down or left and right parallel, so that the bamboo boards placed in the middle position are heated and have a poor drying effect, require a longer time, and the drying is uneven. In addition, the existing hot air drying device requires manual feeding of single bamboo boards. Since the bamboo boards are inside the hot air drying device, it is not convenient to take them out or turn them over manually. Therefore, we propose a hot air drying device for bamboo boards. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is that the blowing angles of the existing bamboo board drying devices are basically vertical or parallel during use, the bamboo boards placed in the middle position are heated and have a poor drying effect, require a longer time, the drying is uneven, and it is not convenient to turn them over and take them out.
[0005] To solve the above technical problems, the technical solution provided by the utility model is a hot air drying device for bamboo boards, including a drying box. A drying port is arranged in the middle of the drying box. A plurality of drying racks are slidably connected inside the drying port. A plurality of air passing ports are arranged on the drying port. Hot air racks are arranged on both sides inside the drying box. The side of the hot air rack close to the drying port is inclined, and guide wind plates are arranged on the upper and lower sides of the drying port on both sides of the hot air rack; A plurality of heating rods and air outlet plates are arranged on the hot air rack in sequence from the side close to the drying port to the inner side of the hot air rack. The back of the air outlet plate is connected with a plurality of air blowers through a plurality of ducts. The plurality of air blowers are arranged outside the drying box and fixed by a protective cover.
[0006] Preferably, the plurality of drying racks are arranged parallel up and down, and a pull handle is arranged at the bottom of the drying rack outside the drying port, and the pull handle is wrapped with a wooden handle.
[0007] Preferably, the middle of the drying rack is a wire mesh structure supported by metal rods, and multiple sliding rails are provided at both sides of the drying rack at the drying openings.
[0008] Preferably, the multiple air inlets are equidistantly arranged inside the drying openings, and the directions of the multiple air inlets are parallel to the blowing directions of the hot air racks on both sides.
[0009] Preferably, the hot air rack is fixed inside the drying oven, and forms an angle of 75 to 78 degrees between the side close to the multiple heating rods and the bottom of the drying opening.
[0010] Preferably, the air guide plates are perpendicularly arranged with respect to the hot air racks, and the two air guide plates on both sides and the two hot air racks on both sides seal the drying opening into a rectangular cavity structure.
[0011] Preferably, the inside of the air outlet plate is partitioned into multiple cavity structures of the same size, and one side of each cavity structure is connected to a conduit, and the other end of the conduit passes through the drying oven and is connected to a blower.
[0012] The advantages of the present utility model compared with the prior art are as follows:
[0013] 1. By being inclined with respect to the bottom of the drying oven, the hot air drying device enables the hot air to be blown out along the inclined direction, synchronously drying the bamboo boards on the multiple drying racks, so that the drying effect of the bamboo boards at the middle position is the same as that of the bamboo boards at the edge.
[0014] 2. By providing multiple drying racks that can be pulled, the bamboo boards can be pulled out from the inside of the drying oven, and there is no need to frequently put hands into the inside of the hot air dryer for work, facilitating operations such as taking out, placing, and turning over the bamboo boards.
