Description

Technical Field

[0001] This utility model relates to the field of cleanroom technology, and in particular to a cleanroom air shower. Background Technology

[0002] A cleanroom is a highly enclosed space where parameters such as air cleanliness, temperature, humidity, pressure, and noise can be controlled as needed. Air showers are an essential passageway into a cleanroom, reducing contamination from incoming materials. An air shower is a versatile local purification device installed between the cleanroom and its external environment. When people and / or goods enter the clean area, they must pass through the air shower to remove dust carried by them, effectively blocking or reducing dust sources from entering the clean area.

[0003] In the prior art, patent CN221288986U describes a cleanroom air shower, which includes an air shower body and a shell and a rotating disk mounted on the air shower body. Fixing frames are fixedly connected to the left and right inner walls of the shell. First motors are fixedly installed on the left and right sides of the shell. Each of the output ends of the two first motors is fixedly connected to a screw rod, one end of which penetrates the shell and extends into the interior of the fixing frame. Moving plates are threadedly connected to the outer peripheral walls of the two screw rods. Each of the two fixing frames has a clearance groove on its opposite side for the moving plates to pass through. This cleanroom air shower, through the contact between the moving plates and the baffles, blocks the rotating disk, stably isolating it and improving its stability. The sliding connection between the limiting plate and the limiting groove supports the moving plates, further improving their stability. Simultaneously, the contact between the rubber pad and the threaded hole reduces impact force, improving the overall performance.

[0004] Existing cleanroom air showers have the following defects: the airflow organization inside the air shower is unreasonable, and the airflow is prone to forming turbulent flow after being ejected, resulting in a large number of "ineffective vortices". These vortices not only cannot effectively impact debris and have low cleaning efficiency, but also consume fan energy. Utility Model Content

[0005] In view of the shortcomings of existing technology, this utility model provides a high-efficiency dust removal air shower for cleanrooms.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A cleanroom air shower includes an air shower body, with a rectifier assembly disposed inside the air shower body. The rectifier assembly includes a honeycomb rectifier grid fixedly connected to the inner side wall of the air shower body. A pair of vortex suppression plates are fixedly connected to both sides of the interior of the air shower body. The vortex suppression plates are inclined. A guide plate is fixedly connected to the bottom of the vortex suppression plates. Grooves are formed on the side walls of the vortex suppression plates. A collection assembly is disposed at the bottom of the air shower body.

[0007] Furthermore, the collection assembly includes a pair of guide plates fixedly connected to the inner sides of the air shower body. The guide plates are inclined, and a fixing frame is fixedly connected to the bottom of the guide plates. A magnetic block is disposed inside the fixing frame.

[0008] Furthermore, a fan is fixedly connected to the side wall of the air shower body, an air filter element is installed inside the fan, and an air guide pipe is fixedly connected to the output end of the fan.

[0009] Furthermore, one end of the air guide tube is fixedly connected to a connected annular air tube, and the bottom of the annular air tube is provided with multiple blowers.

[0010] Furthermore, a guide cone is fixedly connected to the inner top wall of the air shower body, and a standing plate is fixedly connected to the inside of the air shower body. Multiple chip removal grooves are opened inside the standing plate.

[0011] Furthermore, a collection box is provided on the inner bottom wall of the air shower body, a baffle is provided on the side wall of the air shower body, and an entrance door is provided on the side wall of the air shower body.

[0012] Furthermore, a handle is fixedly connected to the side wall of the shield, a bolt is provided on the outer side of the shield, and threaded holes that match the bolts are provided on the side walls of both the shield and the air shower body.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This application uses a rectifier assembly to transform turbulent flow into laminar flow, preventing the formation of ineffective vortices due to excessive airflow disturbance and concentrating airflow energy for impacting debris. The combined use of a honeycomb rectifier grid, vortex suppression plate, grooves, and guide plates reduces ineffective airflow disturbance and improves debris removal efficiency. The collection assembly, with its combination of magnetic blocks, collection box, and guide plates, achieves a balance between gravity settling and magnetic adsorption, accommodating both ordinary debris and metal particles for more thorough purification and improved overall device practicality.

Detailed Implementation

[0016] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0017] Example 1: As Figure 1-4 The cleanroom air shower shown includes an air shower body 1. The air shower body 1 is equipped with a rectifier assembly inside. The rectifier assembly includes a honeycomb rectifier grid 12 fixedly connected to the inner wall of the air shower body 1. The honeycomb rectifier grid 12 can divide the turbulent airflow generated by the fan 2 into multiple small channels. By reducing the turbulence of the airflow through the fine pores, the airflow is transformed from turbulence into a stable and orderly laminar flow, reducing the generation of ineffective vortices and improving the uniformity of the airflow.

[0018] A pair of inclined vortex suppression plates 3 are fixedly connected to both sides of the interior of the air shower body 1. The inclination angle can guide the airflow direction. The side walls of the vortex suppression plates 3 are provided with grooves 19. The grooves 19 are evenly distributed in a regular shape. The regularly distributed grooves 19 can further divide the passing airflow. By using the friction damping and corner cutting effect of the regularly shaped hole walls on the airflow, large-scale vortices in different directions are broken up, reducing airflow energy loss and converting large vortices into small-scale, low-energy micro vortices. The bottom of the vortex suppression plates 3 is fixedly connected to a guide plate 4. The guide plate 4 can accurately guide the airflow that has been rectified and suppressed to the part that needs to be cleaned according to the shape and position of the human body or goods, avoiding airflow waste, ensuring that the airflow evenly covers the surface of the human body or goods, and improving the efficiency of debris removal.

[0019] A collection assembly is provided at the bottom of the air shower body 1. The collection assembly includes a pair of inclined guide plates 15 fixedly connected to the inner sides of the air shower body 1. The inclined guide plates 15 can use gravity to guide the debris blown down by the airflow to a fixed position, so as to avoid secondary pollution caused by the debris in the air shower body 1. A fixing frame 16 is fixedly connected to the bottom of the guide plate 15. The fixing frame 16 is used to fix the magnetic block 17. The magnetic block 17 is provided inside the fixing frame 16. The magnetic block 17 can attract the fine metal debris suspended in the air and adsorb it onto the surface of the guide plate 15. Together with the guide plate 15, the metal debris and ordinary debris are classified and collected, further improving the purification effect of the air shower.

[0020] Example 2: Figure 1-4 As shown, based on the above embodiment 1, a fan 2 is fixedly connected to the side wall of the air shower body 1. The fan 2 provides the power source for the entire air shower. The air filter core installed inside it can perform preliminary filtration of the air drawn in from the outside, intercepting large particles of dust, hair and other impurities, and ensuring the cleanliness of the airflow entering the air shower.

[0021] The output end of the blower 2 is fixedly connected to an air guide pipe 11, which is used to transport the clean airflow output by the blower 2 to the annular air pipe 8. During the transportation process, the airflow diffusion is restricted, energy loss is reduced, and the airflow pressure is kept stable. One end of the air guide pipe 11 is fixedly connected to the annular air pipe 8, which can evenly distribute the airflow input by the air guide pipe 11 to each blower head 10. Its annular structure allows the airflow to be evenly distributed along the circumference, ensuring that each blower head 10 receives an equal amount of clean airflow. Multiple blower heads 10 are set at the bottom of the annular air pipe 8. The multiple blower heads 10 are arranged at a certain interval and can spray clean high-speed airflow from different angles to personnel or goods entering the air shower room. The impact force of the airflow is used to effectively remove dust and debris attached to the surface. A guide cone 9 is fixedly connected to the inner top wall of the air shower room body 1. The guide cone 9 can guide and converge the airflow above the annular air pipe 8, avoid the formation of turbulence or vortex at the top, and make the airflow flow into the annular air pipe 8 more smoothly, thereby improving the airflow transmission efficiency.

[0022] A standing platform 13 is fixedly connected inside the air shower body 1, providing a standing platform for personnel entering the air shower. Multiple debris troughs 14 are provided inside the platform to collect debris blown down by the airflow. The debris falls through the debris troughs 14 into the bottom of the air shower, preventing secondary pollution inside the air shower. A collection box 18 is installed on the bottom wall of the air shower body 1 to collect various debris falling from the debris troughs 14, facilitating regular cleaning and maintaining the cleanliness of the air shower interior. A shielding plate 7 is installed on the side wall of the air shower body 1 to shield and protect the collection components at the bottom of the air shower, preventing external debris from entering and facilitating... Maintenance is performed on components such as the collection box 18; an entrance door 20 is provided on the side wall of the air shower body 1, which is the passage for personnel or goods to enter and exit the air shower. With the help of an electronic interlock device, it can prevent unpurified air from entering the clean area; a handle 5 is fixedly connected to the side wall of the shield 7, which makes it easy for operators to open or close the shield 7, improving the convenience of maintenance operations; a bolt 6 is provided on the outside of the shield 7, and threaded holes that match the bolt 6 are opened on the side wall of both the shield 7 and the air shower body 1. By the cooperation of the bolt 6 and the threaded hole, the shield 7 can be firmly fixed to the side wall of the air shower body 1. When maintenance is required, the bolt 6 can be removed to remove the shield 7, which is convenient and quick.

[0023] Working principle of this device: When using this device, personnel enter the air shower body 1 through the entrance door 20, stand on the standing plate 13, and start the fan 2. The fan 2 sends clean airflow through the air guide pipe 11 into the annular air pipe 8, and sprays it towards the human body through multiple blowers 10. Before the airflow comes into contact with the human body, it passes through the honeycomb rectifier grid 12, which reduces the turbulence of the sprayed airflow by more than half. The airflow passes through the vortex suppression plate 3, which breaks up large-scale vortices, and then flows towards the human body through the guide plate 4. Debris falls into the collection box 18 through the debris dropper 14 and the guide plate 15. The magnetic block 17 attracts small metal debris floating in the air to the guide plate 15. During maintenance, the shield plate 7 can be removed by disassembling the bolts 6 to clean the collection box 18 and the guide plate 15.
