Description

Technical Field

[0001] This utility model relates to the field of cleanroom ventilation technology, and in particular to an adjustment structure and a cleanroom ventilation device. Background Technology

[0002] A cleanroom is a well-sealed space where parameters such as air cleanliness, temperature, humidity, pressure, and noise are controlled as needed.

[0003] In existing cleanroom ventilation equipment in pharmaceutical workshops (such as the technical solution in publication number CN214619945U), the airflow regulation mechanism has significant limitations. Traditional equipment mostly uses fixed ventilation holes or simple baffle structures, which have a small airflow regulation range and low precision, making it difficult to meet the dynamic airflow parameter requirements of cleanrooms under different production processes. In addition, the fans and filter components of existing equipment are usually integrated and fixedly installed, which requires disassembling the entire ventilation system for maintenance. This not only increases downtime but also easily leads to a decrease in sealing performance due to frequent disassembly, affecting the stability of the cleanroom environment. At the same time, the non-removable design of the filter structure makes the filter replacement cycle short and cleaning difficult, further increasing operation and maintenance costs. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable structure and cleanroom ventilation equipment. Through the cooperation of a fixed air vane and a rotatable adjusting disc, the airflow is controlled in stages by adjusting the offset between the ventilation holes and the adjusting holes. A servo motor drives the adjusting disc to rotate precisely. Combined with a low-friction structure of limit balls and annular slide rails, this results in higher airflow adjustment accuracy and faster response, meeting the dynamic process requirements of cleanrooms. The mounting ring and ventilation channel form a quick-assembly and disassembly structure through limit slides and limit slide grooves, facilitating fan maintenance. Simultaneously, the filter structure is double-fixed with mounting screws and limit retaining rings, making filter removal more convenient, thus reducing the replacement cycle and maintenance costs.

[0041] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0042] Example 1

[0043] Please refer to Figures 1 to 14 As shown, an embodiment of the present invention provides an adjustment structure, including: an air volume adjustment component 3, the air volume adjustment component 3 including a fixed air plate 301 and an adjustment mechanism 302 used in conjunction with the fixed air plate 301, the fixed air plate 301 having a plurality of ventilation holes 3011 arranged at equal intervals, the adjustment mechanism 302 including a rotatable adjustment disk 3021, and the adjustment disk 3021 having a plurality of adjustment holes 30211 corresponding one-to-one with the plurality of ventilation holes 3011;

[0044] By adopting the above technical solution, the fixed air vane 301 and the rotatable adjusting disk 3021 work together to achieve graded airflow control by adjusting the offset between the ventilation holes 3011 and the adjusting holes 30211. The servo motor 30241 drives the adjusting disk 3021 to rotate precisely, and the low-friction structure of the limiting ball bearing 30221 and the annular slide rail 3023 makes the airflow adjustment more accurate and the response speed faster, meeting the dynamic process requirements of cleanrooms.

[0045] To achieve precise graded control of air volume, in this utility model, a limiting ring 3022 is fixedly connected to the edge of the side of the adjusting plate 3021, and an annular slide rail 3023 is slidably connected on the limiting ring 3022. The servo motor 30241 drives the adjusting plate 3021 to rotate precisely. With the low friction structure of the limiting ball 30221 and the annular slide rail 3023, the air volume adjustment accuracy is higher and the response speed is faster, meeting the dynamic process requirements of the clean room.

[0046] To ensure the stable rotation of the adjusting disc 3021, in this invention, the side of the limiting ring 3022 is provided with several limiting balls 30221 arranged at equal intervals, and the side of the limiting ring 3022 near the annular slide rail 3023 is rolledly connected to the inner wall of the annular slide rail 3023 through the limiting balls 30221. This rolling connection method greatly reduces the frictional resistance when the adjusting disc 3021 rotates, improves the sensitivity and efficiency of adjustment, and at the same time reduces wear and extends the service life of the equipment.

[0047] To achieve automatic driving of the regulating disc 3021, in this utility model, a mounting bracket 3024 is fixedly connected to the inner wall of the annular slide rail 3023. A servo motor 30241 for driving the regulating disc 3021 to rotate is mounted on the side of the mounting bracket 3024. The output shaft of the servo motor 30241 is fixedly connected to the center of the side of the regulating disc 3021. The servo motor 30241 can accurately control the rotation angle and speed of the regulating disc 3021, realize the automatic adjustment of air volume, and improve the intelligence level of the equipment.

[0048] Example 2

[0049] Please refer to Figures 1 to 14 As shown, an embodiment of the present invention provides a cleanroom ventilation device, including: a ventilation channel 1, a ventilation filter assembly 2 installed inside the ventilation channel 1, and any of the air volume adjustment assemblies 3 in embodiment 1, wherein the fixed air plate 301 and the annular slide rail 3023 are both fixedly connected to the inner wall of the ventilation channel 1.

[0050] By adopting the above technical solution, the mounting ring 201 and the ventilation channel 1 form a quick disassembly and assembly structure through the limiting slide strip 2011 and the limiting slide groove 2012, which facilitates the maintenance of the fan 202. At the same time, the filter structure 203 is double-fixed by the mounting screw 2033 and the limiting retaining ring 2034, making the filter screen 2032 easier to disassemble, thereby reducing the replacement cycle and thus reducing the operation and maintenance cost.

[0051] In order to enable the quick installation and disassembly of the fan 202 and the filter structure 203, in this utility model, the ventilation filter assembly 2 includes an installation ring 201 that is slidably disposed inside the ventilation channel 1, the fan 202 is installed on the installation ring 201, and a detachable filter structure 203 is installed on the side of the installation ring 201.

[0052] To ensure the stable sliding of the mounting ring 201, in this utility model, two symmetrically arranged limiting slide bars 2011 are fixedly connected to the mounting ring 201. The inner wall of the ventilation channel 1 is provided with a limiting slide groove 2012 that matches the limiting slide bars 2011. The cooperation between the limiting slide bars 2011 and the limiting slide groove 2012 effectively restricts the radial displacement of the mounting ring 201 and ensures the stability of the sliding of the mounting ring 201.

[0053] To enable quick replacement of the filter screen 2032 and the fan 202, in this utility model, the filter structure 203 includes a filter frame 2031 slidably disposed on the inner wall of the mounting ring 201. The filter screen 2032 is fixedly connected to the inner wall of the filter frame 2031. Two mounting screws 2033 are symmetrically arranged on the filter frame 2031. The mounting ring 201 and the filter frame 2031 are fixedly installed on the inner wall of the ventilation channel 1 by the mounting screws 2033. By loosening the mounting screws 2033, it is easy to disassemble the filter screen 2032 and the fan 202 installed on the mounting ring 201.

[0054] To prevent the filter frame 2031 from shifting during installation, in this invention, a limiting ring 2034 is fixedly connected to the edge of the side of the filter frame 2031 for limiting the filter frame 2031. The limiting ring 2034 plays a positioning and limiting role during installation, ensuring the accurate installation of the filter frame 2031.

[0055] The working principle of this invention is as follows: Through the coordinated operation of the airflow regulating component 3 and the ventilation and filtration component 2, a stable and clean air environment is provided for the cleanroom. The servo motor 30241 in the airflow regulating component 3 drives the regulating disk 3021 to rotate. The airflow is adjusted by the offset between the regulating hole 30211 on the regulating disk 3021 and the ventilation hole 3011 on the fixed air plate 301, achieving precise airflow control. The fan 202 in the ventilation and filtration component 2 provides ventilation power, and the air enters the cleanroom after being filtered by the filter screen 2032 in the filtration structure 203. The detachable design of the mounting ring 201 and the filter frame 2031 makes the maintenance and repair of the fan 202 and the filter screen 2032 more convenient and quick.
