Description

Technical Field

[0001] The utility model belongs to the technical field of smoke exhaust pipes, in particular to a smoke exhaust pipe for a restaurant. Background Art

[0002] As people's living standards continue to improve, people's requirements for the environment and the quality of life are getting higher and higher. However, in real production and life, there are often various types of pollution, including active pollution generated by hotel operations, which greatly affects people's living environment.

[0003] For example, publication number CN106621613A2 proposes a smoke exhaust duct for a restaurant, comprising a duct body, a waste heat collection device, a smoke exhaust purification device and a smoke exhaust power device, wherein the waste heat collection device, the smoke exhaust purification device and the smoke exhaust power device are respectively arranged inside the duct body, the waste heat collection device comprises a water storage tank, a smoke exhaust pipe, a cold water inlet pipe and a hot water outlet pipe, the smoke exhaust purification device comprises a first oil stain filter, a second oil stain filter, a third oil stain filter, a first smoke filter and a second smoke filter, an oil stain collection device is arranged at the bottom of the smoke exhaust purification device, and sealing rings are arranged at the connections between the smoke exhaust pipe and the water storage tank, between the smoke exhaust pipe and the duct body, and between the smoke exhaust pipe and the first partition.

[0004] However, in the implementation of relevant technologies, it was found that the smoke exhaust duct used in the above-mentioned restaurants still has the following problems: during the actual use of the above-mentioned device, the design of the first oil stain filter, the second oil stain filter, the third oil stain filter, the first smoke filter and the second smoke filter effectively enhances the sewage purification capacity of the smoke exhaust duct. Although the above-mentioned device has the sewage purification capacity, the filter adsorbed on the inside of the ventilation duct cannot be effectively cleaned for a long time and will breed bacteria. The oil stains attached to the filter also cause blockage, which easily makes the smoke exhaust not smooth, thereby affecting the normal use of the smoke exhaust duct. At the same time, it is not convenient to replace the filter inside the duct. Therefore, an improvement is now made to a smoke exhaust duct used in restaurants. Utility Model Content

When reaching the top of the first slide rail 7, the filter 13 is pulled horizontally, so that the filter 13 is separated from the slot 11 under the action of the plug block 12, and then the filter 13 is taken out from the pipe body 1, and after taking it out, it is replaced and the filter 13 is installed in the slot 11 through the plug block 12, and the first motor 9 is driven to rotate counterclockwise so that the filter 13 passes through the limit grooves provided in the replacement box 4 and the pipe body 1. Reach the interior of the pipe body 1, and plug and fix the bottom of the filter 13 with the installation groove 21 opened in the pipe body 1, so that the filter 13 is not easy to fall off or deform during the exhaust process. When the filter 13 needs to be cleaned, the second motor 16 can be driven to make the output shaft of the second motor 16 drive the second screw 15 to rotate, and then the second movable seat 17 outside the second screw 15 moves up and down repeatedly. During the movement, the second movable seat 17 drives the connected piston rod 18 to move synchronously, and then drives the cleaning plate 19 connected to the rod 18 to move. During the movement, the bristles 6 on the outside of the cleaning plate 19 come into contact with the filter 13, and then the oil stains adsorbed on the filter 13 are scraped and cleaned.
