Description

Technical Field

[0001] This utility model belongs to the field of air purification technology, and in particular relates to an air conditioning duct for cleanrooms. Background Technology

[0002] Cleanrooms, also known as clean rooms or dust-free workshops, are enclosed spaces that confine indoor pollutants within a specific range by controlling parameters such as airborne particles, temperature, humidity, pressure, and airflow organization. Their core purpose is to provide a clean environment for specific processes or experiments and avoid interference from pollutants. Air purification is an important component of cleanrooms, and air conditioning ducts are an important structural component in the air purification process, mainly used to deliver fresh, clean air.

[0003] A document with publication number CN220379934U discloses an air conditioning duct mechanism for a cleanroom, including a T-shaped three-way pipe formed by the interconnection of a first pipe and a second pipe. An adjusting screw is inserted through the outer end face of the second pipe at the center position of the inner wall of the first pipe. A rotating shaft is inserted through two mounting seats at the upper and lower ends. A valve plate is respectively provided on the two rotating shafts. A connecting seat is rotatably provided on the end face of the adjusting screw that extends into the second pipe. A fixed seat is also provided in the middle of the outer end face of the connecting seat. Two rocker arms are hinged on the fixed seat. A hinge seat is provided on the opposite end face of the two valve plates at the corresponding position of the rocker arms. The ends of the two rocker arms away from the fixed seat are respectively connected to the hinge seat.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The air conditioning duct mechanism mentioned above drives two valve plates to rotate synchronously by adjusting the screw, thereby realizing the synchronous adjustment of the ventilation volume of the two second ducts. However, in use, it is not convenient to adjust the ventilation volume of a single second duct according to the needs, thus making it inconvenient to adjust the local air supply volume of the clean room individually.

[0006] 2. The air conditioning duct system described above delivers fresh, clean air to different areas within the cleanroom through the first and second pipes. However, during use, the first and second pipes lack shock-absorbing structures, causing them to vibrate during air transport due to gas impacting the inner walls of the pipes. This not only generates significant noise but may also affect the sealing of the pipe connections.

[0007] To address these issues, we provide an air conditioning duct for cleanrooms. Utility Model Content

[0008] The purpose of this utility model is to provide an air conditioning duct for cleanrooms. By driving two valve plates to rotate synchronously through a first threaded rod, the ventilation volume of two branch pipes can be adjusted synchronously.

[0032] Example 1

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this is the first embodiment of the present invention. This embodiment provides an air conditioning duct for a cleanroom, including a main pipe 1 and multiple branch pipes 2 located on both sides of the main pipe 1. An adjustment assembly 3 is provided at the connection between the main pipe 1 and the branch pipes 2.

The second threaded rod 303 drives one of the valve plates 306 to rotate, realizing the adjustment of the ventilation volume of a single branch pipe 2. This solves the problem that the existing system is inconvenient to adjust the ventilation volume of a single branch pipe 2 according to needs.

[0034] Specifically, the first threaded rod 301 is rotatably connected to the bottom of the main pipe 1. A lifting plate 302 is threadedly connected to the first threaded rod 301. The two sides of the lifting plate 302 are threadedly connected to the second threaded rod 303. The bottom end of each of the second threaded rods 303 is fixedly connected to a second handwheel 303a. The top end of each of the second threaded rods 303 is fixedly connected to a U-shaped frame 304. A rack 305 is fixedly connected to the vertical support arm of each of the U-shaped frame 304. Two valve plates 306 are provided and are rotatably connected to the inside of the branch pipes 2 located on both sides of the main pipe 1. The first threaded rod 301 is used to drive the lifting plate 302 to rise and fall. The lifting plate 302 is used to drive the two valve plates 306 to rotate synchronously. The second threaded rod 303 is used to drive the U-shaped frame 304 to move relative to the lifting plate 302. The U-shaped frame 304 is used to install the rack 305 and drive the rack 305 to move.

The lifting plate 302 drives the two U-shaped frames 304 and the rack 305 to move synchronously, thereby making the valve plates 306 in the two branch pipes 2 rotate synchronously, realizing the synchronous adjustment of the ventilation volume in the branch pipe 2. When it is necessary to adjust the ventilation volume in a certain branch pipe 2 individually, the second handwheel 303a is rotated. The second handwheel 303a drives the second threaded rod 303 to rotate synchronously. The second threaded rod 303 drives the designated rack 305 to move through the U-shaped frame 304. The rack 305 drives the designated valve plate 306 to rotate through the adjusting gear 306b, realizing the adjustment of the ventilation volume in the individual branch pipe 2.

[0039] Example 2

[0040] Please see Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, this is the second embodiment of the present invention.

[0041] Specifically, the mounting frame 401 is attached to the bottom of the main pipe 1. Mounting plates 404 are fixedly connected to both sides of the bottom of the mounting frame 401. Inner rods 405 are fixedly connected to the front and rear ends of the upper surface of the mounting plates 404. Sleeve rods 406 are movably fitted onto the top of each inner rod 405. Fixing plates 407 are fixedly connected to the top of each sleeve rod 406. Shock-absorbing springs 408 are fitted onto the outer side of the inner rods 405. The two ends of the shock-absorbing springs 408 are fixedly connected to the upper surface of the mounting plate 404 and the bottom end of the sleeve rods 406, respectively. The mounting frame 401 is designed to... The main pipe 1 is installed. The mounting plate 404 is used to connect the inner rod 405 and the mounting frame 401. The sleeve rod 406 is filled with damping fluid. The inner rod 405 and the sleeve rod 406 are used to dissipate the vibration energy between the mounting plate 404 and the fixed plate 407. The fixed plate 407 is used to fix the mounting frame 401 in the clean room. The shock-absorbing spring 408 is used to convert the vibration potential energy between the mounting plate 404 and the fixed plate 407 into the kinetic potential energy between the inner rod 405 and the sleeve rod 406.

[0042] Furthermore, the top two sides of the mounting frame 401 are movably connected with clamping plates 402, which are respectively attached to the two sides of the main pipe 1. The top of the clamping plates 402 is movably connected with L-shaped plates 403, and the horizontal support arms of the L-shaped plates 403 are respectively attached to the top two sides of the main pipe 1.

[0043] The mounting frame 401 is internally rotatably connected to a third threaded rod 401a. The third threaded rod 401a extends to the outer sides of the mounting frame 401 and is fixedly connected to a first knob 401b. The outer sides of the third threaded rod 401a are threadedly connected to sliders 401c. The third threaded rod 401a is a bidirectional threaded rod. When the third threaded rod 401a rotates forward, it drives the two sliders 401c to move towards each other. When the third threaded rod 401a rotates in reverse, it drives the two sliders 401c to move away from each other. The clamping plates 402 are fixedly connected to the top of the sliders 401c.

The top of the first ear seat 403a on the card plate 402 is rotatably connected to the fourth threaded rod 402a. The top of the fourth threaded rod 402a is fixedly connected to the second knob 402b. The first ear seat 403a on the L-shaped plate 403 is threadedly connected to the outer wall of the fourth threaded rod 402a.

[0045] A second ear seat 403b is fixedly connected to the top of the front and rear end faces of the card plate 402 and the vertical support arm of the L-shaped plate 403. A second slide rod 402c is fixedly connected to the top of the second ear seat 403b on the card plate 402.

[0046] The rest of the structure is the same as in Example 1.

[0047] The operation process of this embodiment is as follows: Rotate the second knob 402b. The second knob 402b drives the L-shaped plate 403 to rise and fall relative to the clamping plate 402 via the fourth threaded rod 402a. When the distance between the L-shaped plate 403 and the clamping plate 402 reaches a preset value, stop rotating the second knob 402b and place the mounting frame 401 at the bottom of the main pipe 1. Then rotate the first knob 401b. The first knob 401b drives the third threaded rod 401a and the third slider 401c to move, thereby enabling… The clamping plate 402 and the L-shaped plate 403 are attached to both sides of the main pipe 1. Finally, the fixing plate 407 is installed at the designated location in the clean room, thus realizing the installation of the main pipe 1 and the branch pipe 2. When the main pipe 1 vibrates, the vibration of the main pipe 1 is converted into the potential energy of the relative motion between the inner rod 405 and the sleeve rod 406 through the elastic deformation and reset action of the damping spring 408. The potential energy of motion is consumed by the friction between the damping fluid in the sleeve rod 406 and the inner rod 405, thereby realizing the vibration reduction of the main pipe 1.
