Description

Technical Field

[0001] This application relates to the field of cleanroom technology, and in particular to a cleanroom fresh air self-circulation system. Background Technology

[0002] Cleanrooms, also known as dust-free workshops, clean rooms, or clean rooms, are enclosed rooms with strict requirements on air temperature, humidity, pressure, and especially dust concentration. Cleanrooms can be classified into various types with different names depending on their purpose and airflow patterns.

[0003] Application No. 202323601489.1 discloses a cleanroom fresh air self-circulation system, relating to the field of cleanroom body technology. The system includes a cleanroom body with a second connecting pipe fixedly connected to one side. In this invention, a pump draws outside air into the cleanroom body through the second connecting pipe, a third connecting pipe, a purification chamber, a first connecting pipe, and an air inlet. The air then enters the third connecting pipe from the other end of the second connecting pipe, is purified in the purification chamber, and re-enters the cleanroom body through the first connecting pipe and the air inlet, thus achieving fresh air self-circulation. By disassembling and replacing the filter element, filter blockage can be prevented, thus preventing unstable airflow. A threaded rod rotates, causing a positioning block to move. The positioning block engages with a positioning groove, positioning the filter screen and facilitating its fixation at one end of the second connecting pipe for filtration of impurities. When the positioning block moves away from the positioning groove, the filter screen can be removed for cleaning.

[0004] The above solution has shortcomings in use. Cleaning the filter element requires tedious disassembly, which increases the workload of staff. Therefore, we propose a cleanroom fresh air self-circulation system to solve the above problems. Utility Model Content

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.

[0022] Please see Figure 1-3In this utility model, a cleanroom fresh air self-circulation system includes a cleanroom body 1. A filter cylinder 5 is provided on the right side of the cleanroom body 1. A filter plate 22 is provided inside the filter cylinder 5. The back of the filter cylinder 5 and the outer surface of the cleanroom body 1 are connected to an air supply pipe 10. The filter plate 22 can filter the fresh air entering the cleanroom body 1, thereby removing impurities in the air.

[0023] Two reinforcing blocks 11 are fixedly connected to the back of the filter cartridge 5. The left side of each reinforcing block 11 is connected to the right side of the cleanroom body 1. The reinforcing blocks 11 can be used to connect the filter cartridge 5 and the cleanroom body 1, ensuring the stability of the cleanroom body 1.

[0024] A suction structure is provided in front of the filter cartridge 5. The suction structure includes a first pump body 7 installed on the right side of the cleanroom body 1. The input end of the first pump body 7 is fixedly connected to the air extraction pipe 8. The output end of the first pump body 7 and the front of the filter cartridge 5 are connected to the exhaust pipe 6. By using the operation of the first pump body 7, outside air can be drawn in, thereby injecting fresh air into the cleanroom body 1.

[0025] A circulation structure is provided above the filter cartridge 5. The circulation structure includes a second pump body 3 installed on the right side of the cleanroom body 1. The input end of the second pump body 3 is connected to the right side of the cleanroom body 1 via a suction pipe 2. The output end of the second pump body 3 is connected to the top of the filter cartridge 5 via a connecting pipe 4. The operation of the second pump body 3 can draw fresh air from inside the cleanroom body 1, enabling the fresh air to circulate.

[0026] The filter cylinder 5 is provided with an annular pipe 9 on the outside, and annular nozzles 20 are connected to the annular pipe 9. Each nozzle 20 extends into the interior of the filter cylinder 5. By injecting water into the annular pipe 9, the nozzles 20 will spray water onto the filter plate 22, which can achieve the effect of rinsing the filter plate 22.

[0027] A rotating rod 17 is rotatably connected to the front of the filter cartridge 5. A cleaning brush 19 is fixedly connected to the rear end of the rotating rod 17. A first gear 14 is fixedly connected to the front end of the rotating rod 17. A motor 13 is installed on the right side of the cleanroom body 1. A second gear 12 that meshes with the first gear 14 is fixedly connected to the output end of the motor 13. When the motor 13 is working, the second gear 12 will drive the first gear 14 and the rotating rod 17 to rotate simultaneously. The rotating rod 17 will then drive the cleaning brush 19 to rotate. The cleaning brush 19 will then clean the impurities on the filter plate 22, further reducing the workload of the staff when cleaning impurities.

[0028] The bottom surface of the filter cartridge 5 is fixedly connected to two drain pipes 15. Each drain pipe 15 is equipped with a sealing plug 16 at its bottom end. The drain pipes 15 can be used to discharge the water after rinsing and to remove the impurities washed off. The sealing plugs 16 can seal the drain pipes 15 to prevent air leakage.

[0029] Two connecting rods 18 are fixedly connected to the outer surface of the rotating rod 17. Each of the two connecting rods 18 is fixedly connected to a scraper 21 at the ends that are far apart from each other. When the rotating rod 17 rotates, the connecting rods 18 and the scraper 21 scrape the inner wall of the filter cylinder 5 to prevent the residue of impurities and water.

[0030] The working principle of this application is as follows: When in use, starting the first pump body 7 can draw air into the filter cartridge 5. After the air is filtered by the filter plate 22, it will enter the cleanroom body 1. Then, the first pump body 7 is turned off and the second pump body 3 is started. The air inside the cleanroom body 1 will be drawn into the filter cartridge 5 for recycling. When it is necessary to treat the impurities on the filter plate 22, water is first added into the annular pipe 9. The nozzle 20 will spray water onto the filter plate 22. At the same time, the motor 13 is started. The motor 13 will drive the second gear 12 to rotate. The second gear 12 will drive the first gear 14 and the rotating rod 17 to rotate. The cleaning brush 19 will clean the impurities on the filter plate 22. The sprayed water mixes with the impurities and flows out from the drain pipe 15, further reducing the workload of the staff in cleaning impurities.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
