[0001] This utility model relates to the field of air showers, and more particularly to an air shower with high-efficiency dust removal. Background Technology

[0002] An air shower is a specialized isolation device for light rinsing and dust removal, commonly found in cleanrooms in industries such as pharmaceuticals, electronics, and medical. Its main function is to use high-speed airflow to wash away dust and particles from the surfaces of personnel or items, achieving a cleaning purpose. Before entering a clean environment, personnel or items may carry dust, particles, and other impurities. The air shower uses high-speed airflow to remove these impurities, reducing the risk of contamination to the clean area.

[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: After high-speed purging, air showers may still retain some impurities that cannot be completely collected or removed. This means that after each use, particles and microorganisms may still exist inside the air shower, increasing the risk of contamination. Furthermore, these residual impurities may be carried into the clean area, causing secondary contamination and hindering the strict control of cleanliness in the environment.

[0004] Therefore, those skilled in the art have provided a high-efficiency dust removal air shower to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency dust removal air shower. After personnel leave through the movable door at the rear of the air shower body, the suction fan is restarted, and the air and residual impurities inside the air shower are drawn into the collection box. The activated carbon filter plate inside the collection box can effectively prevent impurities from flowing back into the air shower with the air.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-efficiency dust removal air shower includes a base, an air shower body fixedly mounted on the upper end of the base, a suction fan fixedly mounted at the middle of the upper end of the air shower body, a three-way pipe fixedly mounted at the input end of the suction fan, a solenoid valve fixedly mounted at each of the three pipes of the three-way pipe, a connecting pipe fixedly mounted at the output end of the suction fan, air outlet boxes fixedly mounted on both sides of the inner end of the air shower body, and an impurity feed screen fixedly mounted at the bottom of the inner end of the air shower body.

[0008] A collection box is movably installed inside the base. Fixing blocks are fixed on both sides of the upper end of the collection box. Activated carbon filter plates are fixed on both sides of the rear side of the inner end of the collection box. A motor is fixed on one end of the rear side inside the base. A lead screw is fixed on the output end of the motor. A guide post is fixed on the other end of the rear side inside the base.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-7 One embodiment provided by this utility model:

[0027] A high-efficiency dust removal air shower includes a base 1, an air shower body 2 fixedly mounted on the upper end of the base 1, a suction fan 3 fixedly mounted at the middle of the upper end of the air shower body 2, a three-way pipe 4 fixedly mounted at the input end of the suction fan 3, solenoid valves 5 fixedly mounted at each of the three pipes of the three-way pipe 4, a connecting pipe 6 fixedly mounted at the output end of the suction fan 3, air outlet boxes 7 fixedly mounted on both sides of the inner end of the air shower body 2, an impurity feed screen 8 fixedly mounted at the bottom of the inner end of the air shower body 2, a collection box 9 movably mounted inside the base 1, fixing blocks 10 fixedly mounted on both sides of the upper end of the collection box 9, activated carbon filter plates 12 fixedly mounted on both sides of the rear inner end of the collection box 9, and a motor 11 fixedly mounted at one end of the rear inner side of the base 1. A lead screw 13 is fixedly installed at the output end of the motor 11. A guide post 14 is fixedly installed at the other end of the rear side inside the base 1. One of the pipes of the three-way pipe 4 passes through the air shower body 2 and leads to the outer end of the air shower body 2. The other two pipes of the three-way pipe 4 are fixedly connected to the two sides of the bottom end inside the base 1. Two connecting pipes 6 are fixedly connected to the air outlet box 7. The impurity feed screen 8 is located on the opposite side of the two air outlet boxes 7. The collection box 9 is movably installed below the impurity feed screen 8. Two activated carbon filter plates 12 are movably installed at the front end of the base 1. One of the two fixing blocks 10 is threaded onto the outer end of the lead screw 13. The two fixing blocks 10 are movably installed on the outer end of the guide post 14. Movable doors are hinged at both the front and rear ends of the air shower body 2.

[0028] Specifically, the pipe at the rear end of the three-way pipe 4 is located inside the cleanroom. A filter plate needs to be installed near the solenoid valve 5. When personnel enter the air shower body 2, the suction fan 3 is turned on, and the solenoid valves 5 on both sides of the three-way pipe 4 are activated at the same time. This allows external air to pass through the suction fan 3, the connecting pipe 6, and finally be discharged through the air outlet box 7, thereby blowing air and removing dust from the personnel inside the air shower.

[0029] Personnel entering the air shower stand on the top of the impurity feed net 8. Impurities on their bodies fall into the collection box 9 through the impurity feed net 8. When personnel leave through the movable door at the rear end of the air shower body 2, impurities still remain in the air shower. At this time, by opening the solenoid valve 5 of the pipeline at the rear end of the three-way pipe 4, the suction fan 3 is started again to draw the air and residual impurities in the air shower into the collection box 9. Since the activated carbon filter plate 12 is installed in the collection box 9, it can effectively prevent impurities from being drawn back into the air shower, ensuring air quality.

[0030] After the motor 11 is started, the lead screw 13 will start to rotate and drive the collection box 9 to move to the outer end of the base 1. The fixing block 10 ensures that the collection box 9 does not detach from the base 1 during the movement, and the guide post 14 is used to limit the collection box 9 from shifting during the movement.

[0031] Once the outer end of the collection box 9 protrudes from the base 1, the activated carbon filter plate 12 is fixed to the collection box 9 by bolts. The operator can easily use tools to remove the bolts and take out the activated carbon filter plate 12, which is convenient for replacement or maintenance of the activated carbon filter plate 12.

[0032] It should be noted that, in order to ensure sealing and air quality, when the air outlet box 7 is closed, the air outlet box 7 and the base 1 maintain a complete seal. This can prevent air leakage and dust leakage, thereby continuously maintaining a clean environment inside the air shower room.

[0033] Working principle: After personnel enter the air shower body 2 through the movable door at the front end, the suction fan 3 is started, and the solenoid valves 5 on both sides of the three-way pipe 4 are opened. At this time, the suction fan 3 will draw outside air through the connecting pipe 6 and finally exhaust it from the air outlet box 7, thus blowing air onto the personnel inside the air shower body 2. The person entering the air shower body 2 stands on the impurity feed screen 8. Impurities on the person will pass through the impurity feed screen 8 and finally fall into the collection box 9. After the person leaves the air shower body 2, there will still be impurities inside the air shower body 2. After opening the solenoid valve 5 on the rear end of the three-way pipe 4, the suction fan 3 is started again. The suction fan 3 will draw the air inside the air shower body 2 into the collection box 9. At the same time, the activated carbon filter plate 12 can prevent impurities from being drawn back into the air shower body 2. After the motor 11 is started, the lead screw 13 will start to rotate, which will drive the collection box 9 to move to the outer end of the base 1. Since there is a fixing block 10 on the upper end of the collection box 9, the fixing block 10 can prevent the collection box 9 from falling off the base 1. The guide post 14 can prevent the collection box 9 from shifting during the movement. At the same time, after the rear end of the collection box 9 is exposed outside the base 1, since the activated carbon filter plate 12 is fixedly connected to the collection box 9 by bolts, the activated carbon filter plate 12 can be removed and replaced simply by unscrewing the bolts.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
