Description

Technical Field

[0001] This utility model relates to the field of workbench technology, and more specifically, to a zero-leakage clean workbench. Background Technology

[0002] Zero-leakage clean benches are devices specifically designed for environments requiring extremely high cleanliness, typically used in industries such as pharmaceuticals, biotechnology, and semiconductor manufacturing. These benches are designed to prevent particulate matter from entering the work area, ensuring that materials handled within the workspace remain uncontaminated.

[0003] Existing clean benches have some shortcomings. Although they can prevent particulate matter from the outside air from entering the work area, the air intake of a zero-leakage clean bench cannot filter impurities or large particles in the incoming air. This makes the internal structure of the zero-leakage clean bench susceptible to impurities, which not only affects the subsequent work effect but also makes subsequent maintenance inconvenient.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a zero-leakage clean bench to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A zero-leakage clean bench includes a bench body, a filter assembly on the top of the bench body, an air inlet on the top of the bench body, multiple limiting seats fixed to the inner wall of the bench body, the inner walls of the multiple limiting seats contacting a filter frame, a filter screen, an activated carbon screen, and a molecular sieve screen installed sequentially from top to bottom on the inner wall of the filter frame, an electrostatic eliminator fixed to the inner wall of the filter frame located below the molecular sieve screen, a treatment assembly on the inner wall of the bench body, and auxiliary components installed on the inner wall of the treatment assembly.

[0008] Furthermore, in order to better control the pressure of the airflow, the processing component includes static pressure boxes fixedly connected to both sides of the inner wall of the workbench. Above the static pressure boxes, there is a negative pressure chamber separated from the inner wall of the workbench. The cavity of the negative pressure chamber is connected to the opening of the air inlet.

[0009] Furthermore, in order to better intercept aerosol particles, the auxiliary components include mounting plates fixed on both sides of the inner wall of the static pressure box, a fan installed above the mounting plates, an air guide hood installed above the fan, a mounting hole opened at the top of the static pressure box, the inner wall of the mounting hole being fixedly connected to the air guide hood, the air guide hood being opposite to the air inlet, and a high-efficiency filter installed at the bottom of the static pressure box.

[0010] Furthermore, multiple fixing nuts are fixed to the inner wall above the worktable body, and connecting screws are threaded onto the inner wall of the fixing nuts. One end of the connecting screw is connected to the top of the static pressure box through a bearing.

[0011] Furthermore, to better ensure that the air in the work area does not leak out, a guide rail is fixed on one side of the workbench, and a baffle is installed on the inner wall of the guide rail.

[0012] Furthermore, in order to better adjust the height of the baffle, an electric telescopic rod is fixed above the baffle. One end of the electric telescopic rod is connected to a fixing plate, and one side of the fixing plate is fixed to one side of the workbench.

[0013] Furthermore, for better operation, a placement opening is provided at the bottom of the workbench, and an operating table is fixed to the inner wall of the placement opening. The top of the operating table contacts the bottom of the baffle plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] (1) By setting the filter components on the workbench, impurities and particulate matter in the external gas can be effectively filtered and removed, improving the quality of the gas entering the work area and reducing the risk of internal structure contamination, thereby improving work efficiency and equipment maintenance convenience. At the same time, the auxiliary components set in the processing components can effectively intercept aerosol particles (such as microorganisms, dust, etc.), thereby further improving the air quality entering the work area.

[0016] (2) By setting up the processing components on the workbench, it is ensured that the air in the work area will not leak out, and the air pressure entering the work area is kept in a relatively stable state. This helps to reduce the impact of airflow fluctuations on the work area and improve the stability of the working environment. At the same time, the fixed plate, electric telescopic rod, shield and guide rail set on the workbench can be raised and lowered easily to adapt to different operating needs, improve the flexibility of the workbench, effectively shield the work area and prevent pollutants in the outside air from entering the work area.

[0028] A guide rail 7 is fixed on one side of the workbench body 1. A baffle plate 8 is installed on the inner wall of the guide rail 7. An electric telescopic rod 9 is fixed above the baffle plate 8. In actual use, the electric telescopic rod 9 can also be replaced with other adjustment devices such as a motor and a synchronous belt or chain. One end of the electric telescopic rod 9 is connected to a fixing plate 10. One side of the fixing plate 10 is fixed to one side of the workbench body 1. A placement opening is provided at the bottom of the workbench body 1. An operating table 11 is fixed on the inner wall of the placement opening. The top of the operating table 11 contacts the bottom of the baffle plate 8.

[0029] Example 2:

[0030] like Figures 1-5 As shown, a zero-leakage clean bench according to an embodiment of the present utility model is provided with a processing component 3 on the inner wall of the bench body 1. The processing component 3 includes a static pressure box 301 fixedly connected to both sides of the inner wall of the bench body 1. A negative pressure chamber 302 is separated from the inner wall of the bench body 1 above the static pressure box 301. The cavity of the negative pressure chamber 302 is connected to the opening of the air inlet. Multiple fixing nuts 5 are fixed on the inner wall of the upper part of the bench body 1. A connecting screw 6 is threadedly connected to the inner wall of the fixing nuts 5. One end of the connecting screw 6 is connected to the upper part of the static pressure box 301 through a bearing.

[0031] An auxiliary component 4 is installed on the inner wall of the processing component 3. The auxiliary component 4 includes mounting plates 401 fixed on both sides of the inner wall of the static pressure box 301. A fan 402 is installed above the mounting plates 401. The fan 402, electric telescopic rod 9, and electrostatic eliminator 206 are electrically connected to a controller during actual use. The controller, fan 402, electric telescopic rod 9, and electrostatic eliminator 206 are electrically connected to an external power supply. An air guide hood 403 is installed above the fan 402. An installation hole is opened above the static pressure box 301. The inner wall of the installation hole is fixedly connected to the air guide hood 403. The air guide hood 403 is opposite to the air inlet. A high-efficiency filter 404 is installed below the static pressure box 301.

[0032] High-efficiency filter 404 mainly uses filter paper made of glass fiber or ultra-fine polypropylene fiber. It intercepts aerosol particles (such as microorganisms, dust, etc.) through a dense fiber layer. In practical use, high-efficiency filter 404 can also be used with (such as HEPA or ULPA filters).

[0033] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0034] In summary, with the help of the above-mentioned technical solution of this utility model, during use, the operator starts the electric telescopic rod 9, which drives the baffle 8 to rise and fall within the guide rail 7. The size of the opening in the work area can be adjusted according to operational needs to prevent external air leakage. After adjustment, the operator places the items to be placed on the operating table 11. Then, the electric telescopic rod 9 drives the baffle 8 to rise and fall within the guide rail 7, so that the baffle 8 contacts the operating table 11 to form a physical seal, further ensuring the airtightness of the work area.

[0035] Then, external air enters the filter frame 202 through the air inlet above the workbench 1, and then the air passes through the following purification layers in sequence: filter screen 203, which intercepts large particulate pollutants such as dust; activated carbon screen 204, which adsorbs volatile organic compounds (VOCs) and odors; molecular sieve screen 205, which selectively adsorbs specific molecules such as moisture or harmful gases; and electrostatic eliminator 206, which eliminates static particles in the air through ionization to prevent particulate matter from contaminating the work area due to electrostatic adsorption.

[0036] The filtered air enters the processing component 3, where the static pressure chambers 301 on both sides and the inner wall of the workbench body 1 form a negative pressure chamber 302. The negative pressure chamber 302 is connected to the air inlet through the air guide hood 403 to ensure uniform airflow distribution. At the same time, after the fan 402 is started, the purified air is transported downward from the static pressure chamber 301 and undergoes secondary filtration through the high-efficiency filter 404 to remove submicron particles. Finally, a unidirectional laminar flow enters the operating area. The fixing nut 5 and connecting screw 6 on the workbench body 1 are fixed to the static pressure chamber 301 through threaded connection to ensure its stability.
