Description

Technical Field

[0001] This utility model belongs to the field of cleanroom technology, and in particular relates to a cleanroom sterilization and purification system. Background Technology

[0002] A cleanroom, also known as a clean space, is a specific space where parameters such as airborne particle concentration, temperature, humidity, pressure, noise, and light are controlled within specific ranges through engineering techniques to meet the extremely high cleanliness requirements of precision manufacturing, scientific experiments, or special processes. Airborne dust particles (including inorganic and organic matter) and microorganisms such as bacteria, fungi, viruses, and spores are the main factors contaminating the cleanroom environment. Sterilization and purification systems are a core component of cleanrooms and can meet higher-level cleanroom requirements, meaning they must not only remove airborne dust particles but also effectively kill or remove airborne microorganisms to achieve specific levels of sterility or microbial control.

[0003] Existing cleanroom sterilization and purification systems typically employ traditional disinfection methods, which are prone to spraying dead zones and struggle to achieve comprehensive and uniform disinfection of the cleanroom's interior space. Furthermore, during necessary air exchange within the cleanroom, bacteria and contaminants from the outside air can easily enter the cleanroom with the fresh air, compromising the clean environment. While ultraviolet (UV) sterilization systems exist, the incoming fresh airflow is not effectively guided and adequately treated, resulting in a low effective kill rate of airborne microorganisms by UV light. This issue has become a pressing problem for those in the field. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a cleanroom sterilization and purification system that can comprehensively disinfect the interior and significantly reduce the impact of ventilation on the internal clean environment.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A cleanroom sterilization and purification system includes a cleanroom body, a top plate on the upper surface of the cleanroom body, a protrusion on the upper surface of the top plate, a purification box fixed on the outer side of the cleanroom body near the protrusion, and a disinfection box fixed on the side of the cleanroom body away from the protrusion. The water outlet of the disinfection box is connected to a diversion pipe inside the cleanroom body. Atomizing nozzles are fixed at the ports of the diversion pipe inside the cleanroom body. A ventilation pipe fixed at the upper port of the purification box is connected to the interior of the cleanroom body. A recess is opened at the bottom of the protrusion, which is connected to the interior of the cleanroom body, and a germicidal lamp is installed inside the recess.

[0006] In a further embodiment of this application, a U-shaped limiting flow plate is fixed to the inner wall of the workshop body near the purification box. The two ends of the limiting flow plate abut against the lower end face of the top plate. By using the limiting flow plate, the flow direction of the gas entering the workshop body is changed, ensuring that the gas flow can pass through the position of the germicidal lamp completely.

[0007] In a further embodiment of this application, the diversion pipe is located on both sides of the limiting flow plate, and the germicidal lamp and the ventilation pipe are both located on the inner side of the limiting flow plate.

[0008] In a further embodiment of this application, an exhaust pipe is fixedly connected to the side wall of the workshop body near the disinfection box. A filter plate is fixed inside the exhaust pipe. An exhaust fan is fixed to the inner side wall of the workshop body at the position corresponding to the exhaust pipe, and the exhaust fan is connected to the inside of the exhaust pipe. The gas passing through the exhaust pipe is filtered by the filter plate.

[0009] In a further embodiment of this application, an air intake machine is installed inside the purification chamber, and a secondary filter is installed inside the purification chamber above the air intake machine. The outlet of the secondary filter is connected to the port of the ventilation pipe, and the inlet of the secondary filter is connected to the outlet of the air intake machine.

[0010] In a further embodiment of this application, a drain pipe is installed inside the purification box below the air intake. The drain pipe is connected to the air intake end of the air intake. A filter plate two is fixed inside the drain pipe. The lower end of the drain pipe passes through the lower end of the purification box. A suction pipe is fixedly connected to the surface of the drain pipe below the filter plate two. The other end of the suction pipe passes through the side wall of the purification box and is installed inside the drain pipe through the filter plate two. Thus, the filter plate two filters the gas entering the drain pipe, preventing dirt from entering the interior of the workshop body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) By connecting the pump body used in the disinfection box to the diversion pipe, the disinfectant in the disinfection box is introduced into the corresponding diversion pipe, and the disinfectant is sprayed into the interior of the workshop body through the atomizing nozzle. The two diversion pipes are installed on both sides of the high position inside the workshop body to comprehensively spray the interior of the workshop body. (2) By setting up a purification box, external air is introduced into the workshop body to exchange the internal space of the workshop body. When external air enters the workshop body, the air is sterilized by a germicidal lamp, which greatly reduces the pollution of the workshop body during the air exchange process.

[0014] The present invention will be further described in a non-limiting manner below with reference to preferred embodiments and accompanying drawings.

[0015] like Figure 1-5 As shown, a cleanroom sterilization and purification system includes a cleanroom body 1. A top plate 2 is provided on the upper surface of the cleanroom body 1. A protrusion 201 is provided on the upper surface of the top plate 2. A purification box 3 is fixed on the outer side of the cleanroom body 1 near the protrusion 201. A disinfection box 4 is fixed on the side of the cleanroom body 1 away from the protrusion 201. A diversion pipe 401 located inside the cleanroom body 1 is connected to the water outlet of the disinfection box 4. Atomizing nozzles 402 are fixed at the ports of the diversion pipe 401 located inside the cleanroom body 1. A ventilation pipe 306 fixed at the upper port of the purification box 3 is connected to the interior of the cleanroom body 1. A recess 203 connected to the interior of the cleanroom body 1 is provided at the bottom of the protrusion 201. A germicidal lamp 202 is installed inside the recess 203. When it is necessary to sterilize and disinfect the interior of the workshop body 1, the disinfectant is poured into the corresponding disinfection tank 4. The pump in the disinfection tank 4 is connected to the diversion pipe 401, and the disinfectant in the disinfection tank 4 is introduced into the corresponding diversion pipe 401. The disinfectant is then atomized and sprayed onto the interior of the workshop body 1 through the atomizing nozzle 402. The two diversion pipes 401 are installed on both sides of the high position inside the workshop body 1, and the atomizing nozzle 402 can spray the interior of the workshop body 1 comprehensively. The purification box 3 introduces external air into the workshop body 1 to ventilate the internal space of the workshop body 1. When external air enters the interior of the workshop body 1, it is irradiated by the germicidal lamp 202 to effectively sterilize the air entering the interior of the workshop body 1.

[0016] A U-shaped limiting flow plate 103 is fixed on the inner wall of the workshop body 1 near the purification box 3. The two ends of the limiting flow plate 103 abut against the lower end face of the top plate 2. The diversion pipe 401 is located on both sides of the limiting flow plate 103. The germicidal lamp 202 and the ventilation pipe 306 are both aligned with the inner side of the limiting flow plate 103. The limiting flow plate 103 is installed inside the workshop body 1. The germicidal lamp 202 and the ventilation pipe 306 are both located inside the workshop body 1. Therefore, after the outside air enters the workshop body 1, the air will spread out from the position of the limiting flow plate 103 to all directions inside the workshop body 1. The use of the limiting flow plate 103 can ensure that the incoming airflow can stably pass under the germicidal lamp 202.

[0017] An exhaust pipe 101 is fixedly connected to the side wall of the workshop body 1 near the disinfection box 4. A filter plate 102 is fixed inside the exhaust pipe 101. An exhaust fan 104 is fixed on the inner side wall of the workshop body 1 at the position corresponding to the exhaust pipe 101, and the exhaust fan 104 is connected to the exhaust pipe 101. When it is necessary to exchange the gas in the workshop body 1, the exhaust fan 104 can be controlled to work, drawing the gas inside the workshop body 1 out from the exhaust pipe 101. At the same time, the exhaust pipe 101 and the ventilation pipe 306 are coordinated to ensure the air circulation between the workshop body 1 and the external environment. The filter plate 102 is installed inside the exhaust pipe 101. When the gas flows inside the exhaust pipe 101, it can be filtered by the filter plate 102.

[0018] The purification chamber 3 is equipped with an air intake 302. Above the air intake 302, the purification chamber 3 is equipped with a secondary filter 301. The outlet of the secondary filter 301 is connected to the port of the ventilation pipe 306, and the inlet of the secondary filter 301 is connected to the outlet of the air intake 302. Below the air intake 302, the purification chamber 3 is equipped with a drain pipe 304. The drain pipe 304 is connected to the inlet of the air intake 302. The drain pipe 304 is fixed with a second filter plate 303. The lower end of the drain pipe 304 passes through the lower end of the purification chamber 3. The drain pipe 304 below the second filter plate 303 is fixedly connected to a suction pipe 305, and the other end of the suction pipe 305 passes through the side wall of the purification chamber 3. With the above-described structure, the intake fan 302 is controlled to operate. External air is drawn into the secondary filter 301 through the suction pipe 305 and the drain pipe 304. The secondary filter 301 performs secondary filtration on the introduced air, and the introduced air is transported to the workshop body 1 through the ventilation pipe 306. The filter plate 303 can filter the intake air. Large particles blocked by the filter plate 303 will fall into the drain pipe 304 below the filter plate 303 and can be discharged directly from the drain pipe 304.
