Description

Technical Field

[0001] The utility model relates to the technical field of biological experiments, in particular to a filter mechanism of a biosafety cabinet which is convenient to disassemble. Background Art

[0002] A biosafety cabinet is a box-type air purification negative pressure safety device that can prevent the aerosol escape of some dangerous or unknown biological particles during the experimental operation process. It is widely used in scientific research, teaching, clinical inspection and production in the fields of microbiology, biomedicine, genetic engineering, biological products, etc. It is the most basic safety protection equipment for the primary protection barrier in laboratory biosafety.

[0003] The operating principle of the existing biosafety cabinet is to suck the polluted air above the operating table into the cavity of the biosafety cabinet through negative pressure. A part of the air is filtered by a high-efficiency filter plate and then discharged from the biosafety cabinet, and the other part is discharged above the operating table after passing through the high-efficiency filter plate to form an effective circulating filtration. Therefore, the filter mechanism is crucial and the high-efficiency filter plate needs to be replaced frequently. The traditional filter mechanism is fixedly installed inside the biosafety cabinet through mechanical connection. When replacing, it is necessary to first remove the outer shell cover of the safety cabinet, then release the mechanical fixation of the filter mechanism, and finally replace the high-efficiency filter plate. The disassembly efficiency of the filter mechanism is low, which is not convenient for replacing the high-efficiency filter plate.

[0004] According to a biosafety cabinet convenient installation and maintenance device provided by the publication number: CN219463436U, including a biosafety cabinet body, an operating mechanism is fixedly connected to the inner side wall of the biosafety cabinet body near the bottom position, a air supply and filtration mechanism is fixedly connected to the inner side wall of the biosafety cabinet body above the operating mechanism, an opening is formed through the top of the biosafety cabinet body, an exhaust filtration mechanism is fixedly connected inside the opening, a hoisting mechanism is fixedly connected to the top of the biosafety cabinet body, and the hoisting mechanism is fixedly connected to the top of the air supply and filtration mechanism. The utility model filters the air in the biosafety cabinet body through the air supply and filtration mechanism and the exhaust filtration mechanism. The hoisting mechanism is used to lift the static pressure box, which is convenient for disassembling and assembling the high-efficiency filter. The hoisting structure is simple and consumes less manpower.

[0005] According to the above-introduced biosafety cabinet convenient installation and maintenance device, the air in the biosafety cabinet body is filtered through the air supply and filtration mechanism and the exhaust filtration mechanism. The hoisting mechanism is used to lift the static pressure box, which is convenient for disassembling and assembling the high-efficiency filter. Since it is necessary to operate and disassemble inside the box body and the replacement process is cumbersome, the replacement efficiency of the high-efficiency filter is low. Therefore, we need to propose a filter mechanism of a biosafety cabinet which is convenient to disassemble. Summary of the Utility Model

Detailed Description of the Embodiment

[0022] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-4, the utility model provides a filter mechanism for a biosafety cabinet that is convenient for disassembly, including a cabinet body 1. A filter assembly 8 is installed in the inner cavity of the cabinet body 1. An opening groove 2 is formed on the left side surface of the cabinet body 1. An operation platform 31 penetrates through the front side surface of the cabinet body 1. A group of concave clamping strips 4 are fixedly installed at the top of the inner cavity of the cabinet body 1. Another group of concave clamping strips 4 are fixedly installed at the top of the operation platform 31. The filter assembly 8 includes a filter box 81 installed inside the cavity of the cabinet body 1. Two clamping blocks 82 are installed on the outer side of the filter box 81. The two clamping blocks 82 are respectively slidably installed inside the two groups of concave clamping strips 4. A fixing rod 84 is fixedly installed on the left side surface of the filter box 81. One end of the fixing rod 84 is fixedly installed with a cover plate 86. The cover plate 86 is located outside the opening groove 2.

[0024] During use, the polluted air is filtered by the filter assembly 8 arranged in the inner cavity of the cabinet body 1. When it is necessary to clean and replace the filter assembly 8, due to the sliding connection relationship between the clamping blocks 82 in the filter assembly 8 and the concave clamping strips 4 in the inner cavity of the cabinet body 1, the cover plate 86 is pulled. The movement of the cover plate 86 can drive the movement of the filter assembly 8. Finally, the cover plate 86 moves to extract the filter assembly 8 from the opening groove 2 of the cabinet body 1, achieving the effect of quickly disassembling the filter assembly 8.

[0025] Two air intake holes 32 are formed at the bottom of the operation platform 31. An exhaust hole 33 is formed at the top of the operation platform 31. A circulating air flow is formed between the intake hole 33 and the exhaust hole 32 to prevent the polluted air from spreading outside the operation platform 31. A UV lamp 34 is fixedly installed on the rear side wall. When the work stops, the UV lamp 34 is started to achieve the effect of disinfecting the operation platform 31.

[0026] An exhaust pipe 5 is connected to the top of the cabinet body 1. The filter box 81 is located between the exhaust pipe 5 and the exhaust hole 33. The air filtered by the filter box 81 is discharged through the exhaust pipe 5 and the exhaust hole 33.

[0027] A fan 6 is fixedly bolted to the top of the operation platform 31. A pressing joint 7 is sleeved on the exhaust end of the fan 6. The fan 6 provides air flow power for the whole device.

[0028] One end of the filter box 81 is provided with a connection hole 83. One end of the pressing joint 7 passes through the connection hole 83 and extends into the interior of the filter box 81. Through the connection relationship between the connection hole 83 and the pressing joint 7, it is ensured that the air flow stably enters the interior of the filter box 81, realizing the sealed docking between the filter assembly 8 and the fan 6 and facilitating the disassembly of the filter assembly 8.

[0029] Two sets of concave grooves 87 are formed inside the filter box 81, and a set of high-efficiency filter plates 88 are movably inserted into the two sets of concave grooves 87. By using the connection relationship between the high-efficiency filter plates 88 and the concave grooves 87, it is convenient to replace the high-efficiency filter plates 88. The connection holes 83 are located between the two sets of high-efficiency filter plates 88 to ensure that the polluted air can pass through the filtration of the high-efficiency filter plates 88.

[0030] A strong magnetic gasket 85 is fixedly installed on the side of the cover plate 86 close to the cabinet body 1, and one side of the strong magnetic gasket 85 is adhesively attached to the outer side wall of the cabinet body 1. By using the adsorptive connection between the strong magnetic gasket 85 and the cabinet body 1, the effect of hermetically connecting the cover plate 86 and the inner cavity of the cabinet body 1 is achieved, and at the same time, the filter assembly 8 is fixed.

[0031] During specific use: When conducting experiments on the operating platform of the cabinet body 1, the fan 6 is started. Through the two air inlet holes 32, the fan 6 sucks the possibly polluted air on the operating platform into the inner cavity of the cabinet body 1 and discharges it into the filter box 81 through the exhaust end of the fan 6. Two sets of high-efficiency filter plates 88 are inserted inside the filter box 81. A part of the air is filtered by the upper high-efficiency filter plate 88 and then discharged to the outside of the cabinet body 1, and the other part of the air is filtered by the lower high-efficiency filter plate 88 and then returned to the operating platform 31, realizing rapid air circulation and avoiding the diffusion of polluted air.

[0032] When it is necessary to clean and replace the filter assembly 8, the operation of the fan 6 is turned off. By pulling the cover plate 86, using the connection relationship between the cover plate 86, the fixing rod 84, and the filter box 81, the filter assembly 8 can be quickly pulled out from the opening groove 2 of the cabinet body 1, facilitating the cleaning of the filter assembly 8. By using the movable connection between the high-efficiency filter plates 88 and the concave grooves 87, the high-efficiency filter plates 88 can be quickly replaced. After the cleaning and replacement are completed, by using the sliding connection relationship between the clamping blocks 82 in the filter assembly 8 and the concave clamping strips 4 in the inner cavity of the cabinet body 1, the filter assembly 8 is quickly inserted back into the inner cavity of the cabinet body 1. Through the setting of the above device, the effect of quickly disassembling the filter assembly 8 is achieved, improving the work efficiency.
