Description

Technical Field

[0001] This utility model relates to the technical field of fume hoods, and in particular to a PP air purification type fume hood. Background Technology

[0002] PP clean air fume hood is a ventilation device made of polypropylene (PP) material. It combines the technical advantages of clean air fume hoods and is designed for experimental environments that require strict control of air quality and prevention of the spread of harmful substances.

[0003] For example, the patent with prior art authorization announcement number CN220005358U belongs to the field of fume hood technology and discloses a clean air type fume hood, including a cabinet body, a coarse filter screen is provided inside the cover, a limiting groove is symmetrically opened on the outer side of the coarse filter screen, and springs are symmetrically fixedly installed on the outer side of the cover. One end of each spring is fixedly connected to a limiting member that penetrates the cover, and one end of the limiting member is inserted into the limiting groove.

[0004] However, it was found during the use of the fume hood that the air filtration and purification effect of the fume hood was poor, which easily led to the spread of harmful substances in the air and reduced the environmental protection effect of the use. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a PP air purification type fume hood that effectively prevents harmful gases inside the cabinet from directly diffusing out, improves the operational safety of personnel, and enhances the reliability of air purification by purifying the air.

[0006] This utility model discloses a PP air purification type fume hood, including a cabinet body and a baffle. An operating port is provided on the outer wall of the cabinet body, and the baffle is installed at the operating port. It also includes an exhaust device, a purification device, a support platform, an operating port, gloves, and an exhaust pipe. The operating port is connected to the baffle, and the gloves are installed on the operating port. The exhaust pipe is connected to the upper part of the outer wall of the cabinet body and is connected to the exhaust device, which is used to draw air into the cabinet. The purification device is located in the upper part of the cabinet body and is used to purify the air inside the cabinet. A support platform is provided in the lower part of the cabinet body to support items. After the baffle is opened, items are placed on the support platform, and then the baffle is closed. Personnel operate the items inside the cabinet through the operating port and wearing gloves, effectively preventing the direct diffusion and discharge of harmful gases from inside the cabinet, thus improving personnel safety. The exhaust device draws air into the cabinet, allowing outdoor air to enter through the lower part of the cabinet. The purification device then purifies the air inside the cabinet, reducing the diffusion of harmful substances in the air inside the cabinet. Simultaneously, the exhaust device performs secondary purification of the air, improving the reliability of air purification.

[0007] Preferably, the purification device includes a flow guide platform, a packing layer, a conveying pipe, a drain pipe, a water inlet pipe, and multiple sets of spray pipes. The flow guide platform is installed on the upper part of the inner side wall of the cabinet. The packing layer is installed on the inner side wall of the cabinet and positioned above the flow guide platform. The bottom end of the conveying pipe communicates with the cabinet body below the flow guide platform, and the top end of the conveying pipe communicates with the cabinet body between the flow guide platform and the packing layer. The drain pipe is connected to the cabinet body above the flow guide platform. The water inlet pipe is installed at the top of the cabinet and is connected to an external water supply device. The multiple sets of spray pipes are all connected to the bottom of the water inlet pipe, and the output ends of the multiple sets of spray pipes are connected to... The cabinet is interconnected; when the exhaust device draws air into the cabinet through the exhaust pipe, the air inside the cabinet is transported through the delivery pipe to the space between the guide platform and the packing layer. Purified water is then supplied to the inlet pipe through an external water supply device, which sprays water onto the packing layer through multiple sets of spray pipes. As the water passes through the packing layer, it forms a water film. The water then falls to the top of the guide platform and is discharged through the drain pipe. The air between the guide platform and the packing layer flows upward through the water film, purifying the air. Finally, the air is discharged outward through the exhaust pipe, improving the air purification effect.

[0008] Preferably, the exhaust device includes a housing, a fan, baffles, and activated carbon layers. The housing is installed on the outer wall of the cabinet, and the bottom end of the exhaust pipe is connected to the housing. The fan is connected to and installed at the bottom of the housing. Multiple sets of baffles are installed alternately on the inner wall of the housing, and multiple sets of activated carbon layers are installed between the multiple sets of baffles. The fan draws air into the housing, and the housing draws air into the cabinet through the exhaust pipe. After the air enters the housing, it is guided and transported by the multiple sets of baffles. The air is adsorbed and purified by the multiple sets of activated carbon layers, and then discharged by the fan, thereby improving the air purification effect.

[0009] Preferably, the support platform includes a cover and a mesh panel. The cover is installed in the lower part of the cabinet, the mesh panel is installed in the top of the cover, and the cover is connected to the outside. When the exhaust pipe draws air into the cabinet, outdoor air enters the cabinet through the cover, improving the airflow convenience inside the cabinet.

[0010] Preferably, it also includes a filter screen, which is installed on the inner side wall of the cabinet; by setting up the filter screen, the air filtration effect entering the cabinet is improved, and outdoor dirt entering the cabinet is reduced.

[0011] Preferably, it also includes a lighting fixture, which is installed at the bottom of the flow guide; by setting up the lighting fixture, the lighting convenience inside the cabinet is improved.

[0012] Preferably, the baffle is made of a transparent material; this improves the convenience for personnel to observe and operate inside the cabinet.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: After the baffle is opened, the items are placed on the support platform, and then the baffle is closed. Personnel operate the items inside the cabinet through the operating port and wearing gloves, thereby effectively preventing the direct diffusion and discharge of harmful gases inside the cabinet and improving the safety of personnel operation. The exhaust device draws air into the cabinet, allowing outdoor air to enter through the lower part of the cabinet. The air inside the cabinet is purified by the purification device, thereby reducing the diffusion of harmful substances in the air inside the cabinet. At the same time, the exhaust device performs secondary purification of the air, improving the reliability of air purification. Attached Figure Description
