Description

Technical Field

[0001] This utility model relates to the field of clean bench technology, specifically to a modular filter assembly installation structure for a clean bench. Background Technology

[0002] Clean benches are indispensable local cleanliness control devices in fields such as biopharmaceuticals, microelectronics manufacturing, laboratory testing, and precision instrument assembly. Their core function is to create an ISO 5 (Class 100) or higher sterile and dust-free working environment through directional laminar airflow and high-efficiency filtration technology, preventing samples, precision components, or experimental materials from being contaminated by airborne particulate matter, microorganisms, and other pollutants. The equipment mainly consists of the bench body, static pressure chamber, intake fan, air intake grille, exhaust grille, and filter components. During operation, the intake fan draws outside air into the static pressure chamber through the air intake grille for pressure stabilization and uniform flow. The filter components then trap particles larger than 0.3μm (filtration efficiency of over 99.99%) and deliver them to the work area in a uniform vertical or horizontal laminar flow. Simultaneously, the exhaust grille completes airflow circulation or purified discharge, ensuring the cleanliness and safety of the operating environment.

[0003] Chinese Utility Model Patent Publication No. CN 215464566 U discloses an ultra-clean workbench. The specification describes a design where the bottom operating panel and side panels are integrally formed from a single mirror-finished stainless steel sheet. The connection points between the operating panel and the side panels are all curved, effectively enhancing the mirror reflection of ultraviolet sterilization spectra at the experimental sample placement area within the workbench. This solves or partially solves the technical problem of optimizing the structural design of existing ultra-clean workbenches to improve sterilization effectiveness. It optimizes the workbench structure, allowing for full utilization of the ultraviolet sterilization spectrum through mirror reflection, thus improving sterilization efficiency. However, this ultra-clean workbench lacks a detachable filter element structure. Over extended use, debris easily accumulates on the filter element surface, reducing filtration efficiency. Damaged components require complete replacement, resulting in high maintenance costs and resource waste. Summary of the Invention

[0022] Specifically, the casters 2 are provided in four identical sets, which are symmetrically distributed at the bottom of the clean bench body 1. The advantage is that the four sets of symmetrically distributed casters 2 form a stable four-point support structure, which keeps the center of gravity balanced during the movement of the equipment and avoids tilting or tipping due to unilateral force. In addition, the casters 2 have a self-locking structure, making them highly practical.

[0023] Specifically, the insert 11 has an "L"-shaped cross-section, which is adapted to the slot 9. The positioning post 10 is adapted to the positioning hole 12. A locking nut 13, which is threadedly connected to the positioning post 10, is provided on the side of the exhaust grille 7 away from the clean bench body 1. The advantages are that the "L"-shaped cross-section of the insert 11 and its adaptation to the slot 9 allow for quick insertion of the exhaust grille 7.

The quick alignment and installation of component 14 with the clean bench body 1 is achieved until the limiting block 1406 is inserted into the limiting groove 16, and the locking bolt 17 passes through the limiting block 1406 and extends into the mounting groove 8, thus realizing the quick installation of the filter component 14. At the same time, the threaded connection means that the filter component 14 can be pulled out along the groove 15 as a whole by simply loosening the locking bolt 17, realizing the quick replacement of the filter element. Finally, the L-shaped cross-section of the insert 11 and its matching with the slot 9 enable the quick insertion of the exhaust grille 7. The precise fit between the positioning post 10 and the positioning hole 12 ensures accurate installation angle and avoids sealing failure due to misalignment. The threaded connection between the locking nut 13 and the positioning post 10 further improves the connection strength between the exhaust grille 7 and the clean bench body 1.
