Description

Technical Field

[0001] The utility model belongs to the technical field of drying devices, and in particular relates to a drying device for a drying room. Background Art

[0002] After the semi-finished aerosol cans have been painted and welded, they need to be dried. That is, they are moved to the bottom of the drying device via a conveyor belt and dried during the transportation process. During the drying process, paint waste gas is generated. Currently, drying rooms on the market (such as the one disclosed in application number 200820084304.0) usually use a blower installed on the drying room and evenly distributed duct fans to extract air from a local area, thereby sucking the waste gas in the drying room into the exhaust pipe. The main disadvantages of this exhaust gas extraction method are: (1) the waste gas is likely to remain in the drying room; (2) the power requirements of the blower and duct fan are relatively large, which increases the cost of equipment use. Summary of the Invention

[0003] In view of the above shortcomings, the technical problem to be solved by the present invention is to provide a drying device for a drying room, which is used to directly suck the exhaust gas generated by drying to prevent the exhaust gas from overflowing into the drying room, thereby preventing the exhaust gas from remaining in the drying room, and at the same time reducing the power of the fan used to extract the exhaust gas, thereby reducing the use cost of the drying room.

[0004] In order to solve the above technical problems, the technical solution adopted by the present utility model is:

[0005] A drying device for a drying room comprises a drying assembly and an exhaust hood for extracting exhaust gas. The drying assembly is provided with a drying pipe, the exhaust hood is fixed to the outside of the drying pipe, and the exhaust hood is provided with an exhaust joint for extracting air from the exhaust hood.

[0006] As a preferred solution of the present invention, a positioning block is installed on the drying tube, the exhaust gas hood is adapted to the positioning block, and the exhaust gas hood is positioned and installed on the drying tube through the positioning block.

[0007] As a preferred solution of the present invention, a positioning groove is provided on the exhaust hood, and the positioning groove is clamped on the outer side of the positioning block.

[0008] As a preferred solution of the present invention, the exhaust hood includes a first cover plate and a second cover plate that are assembled with each other, and positioning grooves are provided on the first cover plate and the second cover plate.

[0009] As a preferred solution of the present invention, a hanging rod is installed on the positioning block.

[0010] As a preferred solution of the present invention, the drying assembly includes a heating pipe and a control box. The drying pipe is fixed to the bottom of the control box, and the heating pipe is arranged inside the drying pipe.

[0011] As a preferred solution of the present invention, a connecting groove is provided in the exhaust hood, and the connecting groove is adapted to the connection between the drying pipe and the control box.

[0012] As a preferred solution of the present invention, the axis of the air extraction joint is tilted relative to the vertical plane, and the tilt angle is °°.

[0013] As a preferred solution of the present invention, the air inlet of the air extraction joint is arranged below the lower end surface of the drying tube.

[0014] As a preferred solution of the present invention, a conveyor belt is provided below the drying device, and an exhaust hood is provided on the outside of the conveyor belt.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) the exhaust gas generated by the drying component during workpiece drying is covered by an exhaust gas hood to prevent the exhaust gas from overflowing into the drying room, thereby preventing the exhaust gas from remaining in the drying room, and thus preventing the residual exhaust gas from affecting the health of employees.

[0016] (2) By setting an exhaust joint on the exhaust hood, the exhaust gas in the exhaust hood can be extracted in time. Compared with exhausting the entire drying room, the volume of exhaust gas required to be exhausted is reduced, thereby effectively reducing the power required by the exhaust fan and reducing the overall use cost of the drying equipment.

The circuit board on which the heat pipe 1-2 works, the exhaust hood 2 is fixed on the outside of the drying tube 1-1, and the exhaust hood 2 is arranged on the outside of the conveyor belt 5, that is, the lower end edge of the exhaust hood 2 is at least lower than the upper end conveying surface of the conveyor belt 5, to ensure that the exhaust gas generated by drying is arranged in the exhaust hood 2 to prevent the exhaust gas from overflowing to the outside of the exhaust hood 2. An exhaust joint 2-1 is provided on the exhaust hood 2, and a flexible pipe is connected to the exhaust joint 2-1. The flexible pipe is connected to the duct fan, and the exhaust joint 2-1 is exhausted by the duct fan, thereby exhausting the exhaust gas in the exhaust hood 2.

[0023] As a preferred embodiment, the length of the drying tube 1-1 is 3-4 meters, and correspondingly, the length of the heating tube 1-2 is also 3-4 meters.

[0024] The exhaust hood 2 includes a first cover plate 2-3 and a second cover plate 2-4 that are assembled with each other. The cross-sectional shape of the first cover plate 2-3 and the second cover plate 2-4 are both L-shaped and are fixed to the two sides of the drying pipe 1-1 by screws. Through holes are provided on the vertical plates of the first cover plate 2-3 and the second cover plate 2-4, and the exhaust connector 2-1 is connected to the through holes, so that the exhaust gas in the exhaust hood 2 can be extracted through the exhaust connector 2-1. Preferably, the axis of the exhaust connector 2-1 is tilted relative to the vertical plane, and the tilt angle is 40°-50°, so that the exhaust connector 2-1 can be connected to the duct fan located above the exhaust hood 2 through a hose. Preferably, the air inlet of the exhaust connector 2-1 is set lower than the lower end surface of the drying pipe 1-1, that is, the position of the through hole is lower than the lower end surface of the drying pipe 1-1, so that the exhaust gas can enter the exhaust connector 2-1.

[0025] In order to facilitate the fixing of the drying assembly 1 on the drying room, a positioning block 3 is installed on the drying tube 1-1, and a hanging rod 4 is installed on the positioning block 3. The hanging rod 4 is connected to the roof of the drying room. Preferably, the hanging rod 4 is a screw structure.
