Description

Technical Field

[0001] This utility model belongs to the field of wood drying, and specifically relates to a drying device for wooden handicrafts. Background Technology

[0002] During the processing of wooden handicrafts, drying equipment is needed to dry the raw materials or finished products to remove excess moisture. This can effectively reduce problems such as cracking and deformation, and ensure that the wooden handicrafts maintain structural stability and beauty after drying.

[0003] Patent application CN202011184377.9 discloses a wood drying device with good drying effect for furniture production. It includes a base plate, a drying box fixedly connected to the top outer wall of the base plate, mounting holes near both sides of the top outer wall of the drying box, and hydraulic cylinders installed on the inner walls of the mounting holes. One end of the piston of the hydraulic cylinder is provided with a ring pipe, and the inner wall of the ring pipe is provided with nozzles that are evenly spaced and distributed in a ring. A fan is provided on one side outer wall of the drying box, and an air guide pipe is provided at the exhaust end of the fan. One end of the air guide pipe is provided with a corrugated pipe, and one end of the corrugated pipe is connected to the ring pipe. A heating box is fixedly connected to one side outer wall of the drying box, so that hot air can be evenly applied to the surface of the furniture, resulting in good drying effect. However, the above-mentioned device also has some problems. After the hot air is sprayed out from the nozzle and comes into contact with the furniture, it will inevitably flow towards the upper area of ​​the drying chamber. Although the ring pipe can move up and down, the disturbance to the hot air is very limited, resulting in uneven temperature inside the drying chamber, reducing drying efficiency and failing to achieve the ideal drying effect. In addition, it cannot be naturally dried or ventilated for cooling, so its applicability is not high. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a drying device for wooden handicrafts, which can ensure uniform temperature inside the drying device, guarantee sufficient contact between hot air and wooden handicrafts, greatly improve the drying effect, and at the same time enable natural air drying and ventilation cooling, thus improving applicability.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows:

[0006] A drying device for wooden handicrafts includes a base, a drying chamber mounted on the base, a door on one side of the drying chamber with an air outlet on the door, an air inlet on the other side of the drying chamber, and a circulating drying system on the drying chamber. The circulating drying system includes a hot air chamber and a negative pressure chamber. The hot air chamber is fixedly connected to the base, and the negative pressure chamber is fixedly installed on the upper plate inside the drying chamber, located directly above the hot air chamber. A booster pump is connected to the hot air chamber, and a negative pressure suction pump is connected to the negative pressure chamber. A heating and dehumidification device is provided between the negative pressure suction pump and the booster pump.

[0007] As a further feature of the above scheme, the upper surface of the hot air box has linearly arranged long slots, and the long slots are provided with uniformly distributed first air holes. The hot air box is connected to the drying box through the first air holes. The lower surface of the negative pressure air box is provided with arrayed second air holes, and the second air holes are arranged vertically corresponding to the first air holes.

[0008] As a further provision of the above scheme, the air outlet device includes an air outlet duct, which is fixedly connected to the box door. An air outlet cone is fixedly connected to the inner side of the air outlet duct, and a first sealing disc is hinged to the outer side of the air outlet duct. A first fan device and a first filter plate are provided inside the air outlet duct.

[0009] As a further provision of the above scheme, the air inlet device includes a main air inlet cone, which is fixedly installed on the drying box. An air inlet duct is fixedly installed at the outer end of the main air inlet cone. A second sealing disc is hinged to the outer end of the air inlet duct. A second fan device and a second filter plate are fixedly connected inside the air inlet duct. The second filter plate is located outside the second fan device.

[0010] This utility model has the following beneficial effects:

[0011] By setting up a negative pressure air box and a hot air box corresponding to each other at the top and bottom inside the drying oven, during drying, the negative pressure suction pump generates negative pressure in the negative pressure air box. The negative pressure air box draws the air out of the drying oven evenly upward through the second air hole. The negative pressure suction pump sends the air into the heating and dehumidification device. After the air is heated and dehumidified, it is sent into the hot air box by the booster pump. The hot air is evenly transported upward through the first air hole to achieve circulation. The hot air forms a uniform upward airflow in the drying oven, which makes the temperature in the drying oven uniform and ensures that the hot air is in full contact with the wooden handicrafts, greatly improving the drying effect.

[0012] When wooden handicrafts need to be air-dried or ventilated for cooling, open the first and second sealing discs, and start the first and second fan devices to allow air to circulate inside and outside the drying chamber. The first and second filter plates filter the air, allowing the wooden handicrafts to air-dry or ventilate for cooling, thus improving the applicability of the device. Attached Figure Description
