Description

Technical Field

[0001] The present invention relates to the technical field of air disinfection and purification devices, and particularly to an air disinfection and purification device for a field rescue medical epidemic prevention shelter. Background Art

[0002] In the field rescue scenario, the air purification of the medical epidemic prevention shelter is the core link to ensure medical safety and personnel health. There are a large number of pathogenic microorganisms such as bacteria, viruses, and fungi in the wild environment. The droplet nuclei transmitted through the air can survive for several hours. With a large number of patients concentrated in the shelter, it is easy to form a cross-infection source. This requires that the purification system meet the medical-grade standard and be combined with ultraviolet disinfection. This operation can ensure the medical operation environment, and the air supply system can prevent external pollution from invading, ensuring the freshness of the air. In the field rescue scenario, the current air disinfection and purification devices for medical epidemic prevention shelters mostly disinfect the air through secondary filtration and ultraviolet illumination, and are combined with the volatilization of chlorine dioxide gel for purification.

[0003] To maintain high air treatment efficiency, a high-power centrifugal fan is usually used to increase the air flow rate. At this time, the supporting large-size air inlet and filter component can expand the processing capacity, but limited by the structure of the fan volute, a special laminar flow effect will be formed on the surface of the filter medium, that is, the air flow mainly enters through the geometric center area of the filter plate, resulting in a higher filtration load on this area. This non-uniform air flow distribution will accelerate the local pressure drop rise of the filter medium. In particular, particulate matter with a particle size of 0.3-5 μm (such as the carrier of virus aerosol) will form a dense accumulation in the middle of the filter plate, resulting in a decrease in the local porosity of the filter material. When the resistance in the middle of the filter material exceeds the critical value, the air flow will be forced to transfer to the edge of the filter plate, resulting in a reduction in the effective filtration area, and ultimately causing a decrease in the air volume and filtration efficiency of the equipment; when disinfecting the air by ultraviolet illumination, the dust in the air will adhere to the surface of the ultraviolet lamp, thus affecting the effect of ultraviolet illumination disinfection; in order to prevent the excessive release of chlorine dioxide gel under the conditions of the optimal temperature and humidity and have an impact on the human body, the concentration of chlorine dioxide gel during configuration ensures that it will not exceed the limit under the optimal conditions. This method may lead to insufficient volatilization concentration of chlorine dioxide gel under adverse conditions, affecting the disinfection effect. Summary of the Invention

[0004] In view of the above problems existing in the prior art that the geometric center of the front filter plate is prone to blockage, the ultraviolet lamp is adhered with dust and affects the disinfection effect, and the volatilization of chlorine dioxide gel is insufficient and affects the disinfection effect, the present application is proposed.

[0023] Inside the housing 11 of the device, in the order from front to back are: the protection plate 121, the front filter plate 13, the fixing plate 211, the rotating fan 153, the disinfection lamp 314, the rear filter plate 413, and the grid plate 411. The purification box 421 is arranged below the rear filter plate 413 and the grid plate 411. Among them, the protection plate 121, the rear filter plate 413, and the grid plate 411 are all detachably arranged. The dust on the front filter plate 13 can be cleaned inside by removing the protection plate 121, and the dust on the disinfection lamp 314 is collected by the filter screen 315 and then discharged through the opening fan 16.

[0024] A temperature measuring device and a chlorine dioxide concentration detecting device are arranged on the housing 11 to understand and grasp the environmental changes in real time.

[0025] As an embodiment provided in the present application, first, the protection plate 121 is installed through the front installation groove 123, then the grid plate 411 and the rear filter plate 413 are installed through the rear installation groove 14, and the volatilization box 422 is installed through the fixing groove 423. When the detection device outside detects that the concentration of chlorine dioxide gel volatilization is insufficient, the biaxial motor 432 is started, and the fan 431 rotates in the volatilization groove 424, accelerating the air flow to improve the volatilization effect of the chlorine dioxide gel. The device can improve the volatilization effect of the chlorine dioxide gel according to the actual situation under adverse conditions; When the disinfection effect of the disinfection lamp 314 on the air is poor, the toggle rod 443 is pulled to stretch the telescopic rod 442. At this time, the toggle rod 443 slides in the toggle groove 444. After the spline rod 433 is inserted into the spline groove 441, the toggle rod 443 is limited and the biaxial motor 432 is started. The cross bar 333 rotates reciprocally following the spline rod 433. The rotation of the cross bar 333 drives the worm 332 to rotate reciprocally, so that the worm gear 331 rotates to drive the lead screw 324 to rotate reciprocally. Since the lead screw 324 is threadedly connected to the moving plate 322, the reciprocal rotation of the lead screw 324 drives the moving plate 322 to move up and down. The cleaning ring 321 moves up and down on the outer wall of the disinfection lamp 314, wiping the dust on it and making it fall into the filter screen 315, and then discharged through the opening fan 16. When the ultraviolet lamp is blocked by dust, the device can clean the outer wall of the ultraviolet lamp to ensure the disinfection effect of ultraviolet irradiation; Through the reciprocal rotation of the cross bar 333 following the spline rod 433, one gear 212 rotates, driving the toothed ring 221 to rotate. Since the toothed ring 221 meshes with the other three gears 212, the other three gears 212 also rotate in the same direction as this gear 212. Thus, the four racks 223 approach or move away from each other, and the elastic cloth 224 is intermittently in an open and contracted state, thereby periodically blocking the center of the front filter plate 13, making the air flow pass through the center and the periphery of the front filter plate 13 periodically. The device avoids dust concentrating at the center of the front filter plate 13, which may cause blockage and affect the filtering effect.

[0026] The above are only the preferred embodiments of the present invention, and are not limitations on the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
