Description

Technical Field

[0001] The utility model relates to the technical field of fume hoods, and specifically to a fume hood with side adsorption. Background Technique

[0002] The cabinet - type exhaust hood is commonly known as a fume hood. Similar to an enclosed hood, the small - part spray - painting cabinet and the chemical laboratory fume hood are typical structures of the cabinet - type exhaust hood. For a large - scale chamber - type fume hood, one side is completely open, and the operator works inside the cabinet, which is mainly used for large - part spray - painting, powder bagging, etc. The working opening of the fume hood has a great influence on the air - flow distribution inside the cabinet, and the air - flow distribution directly affects the working effect of the cabinet - type exhaust hood. The local exhaust hood is an important part of the local exhaust system, and its efficiency has a very important impact on the technical and economic performance of the entire exhaust system. A well - designed local exhaust hood can obtain the best control effect with a smaller air volume and ensure that the concentration of harmful substances in the working area meets the regulations of the national health standards.

[0003] During the use of the above - mentioned fume hood, the exhaust gas generated inside the fume hood is discharged through the exhaust mechanism. During the discharge of the exhaust gas, it is often necessary to filter and purify the exhaust gas. Since there are relatively large particulate matters in the generated exhaust gas, the relatively large particulate matters enter the inside of the exhaust mechanism along with the air flow, which is likely to cause blockage inside the exhaust mechanism. Moreover, the filter screens and pipelines inside the exhaust mechanism are affected in terms of use effect due to the accumulation of relatively large particulate matters. In view of this, we propose a fume hood with side adsorption. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fume hood with side adsorption to solve the problems raised in the above - mentioned background technique.

[0005] To achieve the above purpose, one of the purposes of the utility model is to provide a fume hood with side adsorption, which includes a fume - hood body and a cleaning mechanism arranged on one side inside the fume - hood body. The cleaning mechanism is used to clean relatively large particulate matters. The fume - hood body includes a cabinet body, a side plate and a mounting plate fixedly arranged inside the cabinet body. A plurality of air inlets are opened at the inner bottom of the mounting plate, and dust filter screens are fixedly arranged inside the plurality of air inlets. The dust filter screens are used to filter relatively large particulate matters in the exhaust gas passing through the air inlets. The cleaning mechanism includes a mounting frame slidably connected to one side surface of the mounting plate. A plurality of cleaning brushes and electrostatic adsorption nets are fixedly arranged inside the mounting frame. The electrostatic adsorption nets, the cleaning brushes and the air - inlet positions correspond to each other. The electrostatic adsorption nets and the cleaning brushes are used to clean the dust filter screens.

[0006] As a further improvement of the technical solution, an activated carbon filter screen, a filter cotton and a filter pipe are arranged inside the fume hood body. The activated carbon filter screen, the filter cotton and the filter pipe are located between the side plate and the mounting plate, and are used for filtering, purifying and removing peculiar smell from the waste gas.

[0007] As a further improvement of the technical solution, two sliding grooves are opened at the inner bottom of the mounting plate. Two sliding blocks are fixedly arranged on the surface of the mounting frame close to the sliding grooves. The two sliding blocks are respectively slidably connected inside the two sliding grooves. A sealing baffle is fixedly arranged at one end of the two sliding blocks away from the mounting frame. The sealing baffle corresponds to the air outlet position and is used for sealing the air outlet during the process of cleaning the dust filter screen.

[0008] As a further improvement of the technical solution, the bristled ends of several cleaning brushes are in close contact with one side surface of the dust filter screen. A sealing gasket is fixedly arranged on one side surface of the sealing baffle close to the mounting plate, and the sealing gasket is in close contact with one side surface of the mounting plate.

[0009] As a further improvement of the technical solution, two electric telescopic rods are fixedly arranged on the surface of the mounting plate close to the mounting frame. The electric telescopic rods are used to drive the mounting frame to lift. The two electric telescopic rods are located above the mounting frame, and the mounting frame is fixedly arranged at the lower ends of the two electric telescopic rods.

[0010] As a further improvement of the technical solution, a maintenance window is arranged inside the mounting plate. The maintenance window includes a maintenance opening opened inside the mounting plate, and a transparent partition is fixedly arranged inside the maintenance opening.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. For the fume hood with side adsorption, by setting a dust filter screen to filter larger particles in the waste gas, it is avoided that larger particles enter the exhaust mechanism, which affects the normal use of the exhaust mechanism. When there are more larger particles accumulated on the dust filter screen, the cleaning mechanism can clean the larger particles on the dust filter screen, improving the ventilation effect of the subsequent dust filter screen and avoiding the influence on the use of the exhaust mechanism caused by the blockage of the dust filter screen.
