Description

Technical Field

[0001] This utility model relates to the technical field of air purification devices, specifically a purification and disinfection device for the air intake section of a clean room. Background Technology

[0002] In modern industrial and scientific research activities, the importance of cleanrooms is becoming increasingly prominent. They are widely used in many fields with stringent environmental requirements, such as electronics, pharmaceuticals, food, and aerospace. A cleanroom is a sealed space where parameters such as air cleanliness, temperature, humidity, pressure, and noise are precisely controlled according to requirements. In some special cleanrooms with extremely high requirements for microbial control, such as biopharmaceutical workshops and sterile laboratories, traditional air intake purification and disinfection devices are insufficient to meet their stringent microbial control standards and cannot effectively prevent the intrusion of external microorganisms, posing significant risks to production and experiments. Air cleanliness is a key factor related to product quality, the accuracy of experimental results, and the health and safety of personnel. The air circulation system of a cleanroom, as a crucial part of maintaining a stable indoor environment, typically includes an air intake section, a filtration section, and a return air section. Among these, the air intake section is responsible for… Introducing fresh air from outside is the primary task in ensuring indoor air quality. Cleanrooms are subject to various sources of contamination, including dust particles and microorganisms in the atmosphere, pollutants carried by the fresh air introduced through the air conditioning system, dust generated by workers, dust from the building envelope and facilities, and pollutants generated during equipment and product manufacturing. All of these pose a threat to the cleanroom environment. To ensure that cleanrooms meet the prescribed cleanliness standards, the supplied air must undergo strict purification and disinfection. Air filtration, which involves installing air filters with different performance characteristics at different parts of the air supply system to intercept suspended particles and microorganisms in the air, is the most widely used air purification method.

[0003] However, existing technologies typically involve spraying disinfectant into the air after dust removal. This method fails to effectively kill airborne germs because the disinfectant cannot fully mix with the air. Therefore, a cleanroom air intake purification and disinfection device has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide a purification and disinfection device for the air intake section of a cleanroom, in order to solve the problem mentioned in the background art that the method of spraying disinfectant into the air after dust removal is ineffective in killing germs in the air because the disinfectant cannot fully mix with the air.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cleanroom air intake section purification and disinfection device, comprising a disinfection box, three limiting boxes fixedly connected inside the disinfection box, multiple screen tubes fixedly connected to the lower surface of each limiting box, an air intake pipe fixedly connected to the right side of the disinfection box, a partition fixedly connected to the left side of each limiting box, a motor fixedly connected to the left side of the disinfection box, a slider fixedly connected to the output end of the motor via a coupling, a lead screw fixedly connected to the right side of the disinfection box, a sleeve fitted on the outer surface of the lead screw, the interior of the partition rotatably connected to the outer surface of the sleeve, three stirring blades fixedly connected to the outer surface of the sleeve, a sliding groove opened inside the sleeve, the interior of the sliding groove slidably connected to the outer surface of the slider, and a filter box fixedly connected to the upper surface of the disinfection box.

[0006] Preferably, a connecting pipe is fixedly connected to the upper surface of the disinfection box, and the end of the connecting pipe away from the disinfection box is fixedly connected to the left side of the filter box. An air outlet pipe is fixedly connected to the upper surface of the filter box.

[0007] Preferably, the filter box is internally fixedly connected with multiple support frames, and two steam-water separator filters are provided at the bottom of the filter box, with the two sides of one steam-water separator filter positioned between the two support frames.

[0008] Preferably, a silver ion filter is provided in the middle of the filter box, and two activated carbon filters are provided at the top of the filter box.

[0009] Preferably, the filter box has multiple blocks fixedly connected inside, and the lower surface of one of the blocks is fixedly connected to the upper surface of a support frame.

[0010] Preferably, each of the blocks has a water guide groove on its upper surface, and the disinfection box has a water passage hole on its upper surface.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This cleanroom air intake purification and disinfection device works by introducing filtered air into the disinfection chamber through the intake pipe. The air enters the limiting box and then the screen tube, where it is refined through pores before entering the chamber and coming into contact with the disinfectant solution. This process disinfects airborne pathogens. The air then moves upward within the chamber, passing through a partition and entering the next limiting box, where it is further refined and disinfected by the next screen tube. Simultaneously, a motor is activated, driving a slider to rotate. This slider, in turn, rotates a sleeve, causing the agitator blades to stir the air within the chamber. The sleeve and lead screw are connected by a threaded connection, causing the sleeve to reciprocate axially. This rotation of the agitator blades further agitates the disinfectant solution, ensuring thorough mixing of the air and solution and effectively disinfecting airborne pathogens.

Three limiting boxes 13 are fixedly connected inside the disinfection box 1. Multiple screen tubes 14 are fixedly connected to the lower surface of each limiting box 13. The screen tubes 14 inject air into the disinfection box 1 for disinfection. An air inlet pipe 6 is fixedly connected to the right side of the disinfection box 1, allowing air to enter the box. A partition 15 is fixedly connected to the left side of each limiting box 13, dividing the disinfection box 1. A motor 2 is fixedly connected to the left side of the disinfection box 1, and the output end of the motor 2 is fixedly connected to a sliding contact via a coupling. Block 11, using motor 2, drives slider 11 to rotate. A lead screw 7 is fixedly connected to the right side of disinfection box 1. A sleeve 8 is fitted on the outer surface of the lead screw 7. The lead screw 7 works with the sleeve 8 to drive the sleeve 8 to move axially. The interior of partition 15 is rotatably connected to the outer surface of sleeve 8. Three stirring blades 9 are fixedly connected to the outer surface of sleeve 8. The stirring blades 9 are used to stir the disinfectant in the device. A sliding groove 10 is opened inside the sleeve 8. The interior of the sliding groove 10 is slidably connected to the outer surface of slider 11. The sliding groove 10 is used to limit the position of slider 11. A filter box 16 is fixedly connected to the upper surface of disinfection box 1.

[0019] The upper surface of the disinfection box 1 is fixedly connected to a connecting pipe 3. The end of the connecting pipe 3 away from the disinfection box 1 is fixedly connected to the left side of the filter box 16. The upper surface of the filter box 16 is fixedly connected to an air outlet pipe 5. The connecting pipe 3 serves to connect the disinfection box 1 and the filter box 16.

[0020] The filter box 16 has multiple support frames 21 fixedly connected inside. Two air-water separator filters 4 are installed at the bottom of the filter box 16. The two sides of one air-water separator filter 4 are set between the two support frames 21. The air-water separator filter 4 is used to separate the disinfectant liquid and water vapor in the disinfected air.

[0021] The filter box 16 is equipped with a silver ion filter 19 in the middle, which further eliminates bacteria and fungi in the air. The top of the filter box 16 is equipped with two activated carbon filters 20, which adsorb foreign objects in the air.

[0022] The filter box 16 has multiple blocks 17 fixedly connected inside. The lower surface of one block 17 is fixedly connected to the upper surface of a support frame 21. The block 17 serves to support and limit the position of the air-water separator filter screen 4.

[0023] Each baffle 17 has a water guide groove 12 on its upper surface and a water passage hole 18 on its upper surface.

[0024] Among them, motor 2 is existing technology and will not be described in detail here. Matching motor 2 are connecting wires, power supply, microcontroller, etc., which are existing structures and will not be described in detail here.

[0025] Working Principle: During use, filtered air to be disinfected is introduced into the disinfection chamber 1 through the air inlet pipe 6. The air enters the limiting box 13 and then the screen tube 14. The air is refined through the pores on the surface of the screen tube 14 before entering the disinfection chamber 1 and coming into contact with the disinfectant solution inside, thus disinfecting the airborne pathogens. The air moves upwards inside the disinfection chamber 1 and, after being blocked by the partition 15, enters the next limiting box 13, where it is further refined through the next screen tube 14, further disinfecting the air. Simultaneously, the motor 2 is started, driving the slider 11 to rotate. The slider 11 then rotates the sleeve 8, causing the stirring blades 9 to agitate inside the disinfection chamber 1. At the same time, the sleeve 8... The screw 7 drives the sleeve 8 to move axially back and forth, causing the stirring blades 9 to move while rotating, further increasing the disturbance of the disinfectant solution inside the disinfection box 1. This allows the air to fully mix with the disinfectant solution, effectively disinfecting the germs in the air. The disinfected air then moves to the disinfection box 1 and enters the bottom of the filter box 16 through the connecting pipe 3. The air is first filtered through the air-water separator filter screen 4 to remove the disinfectant solution. The disinfectant solution is then passed into the interior of the disinfection box 1 through the water guide trough 12 and the water passage 18 for recovery. This process prevents the air from carrying the disinfectant solution out of the device. The air is then further disinfected through the silver ion filter screen 19 and adsorbed by two activated carbon filters 20, resulting in thorough purification.
