[0001] The utility model relates to the technical field of air purification equipment, in particular to a laboratory tail gas purifier. Background Art

[0002] In enclosed spaces such as medical operating rooms, biological laboratories, or garbage disposal rooms, the air in the space is easily rich in bacterial aerosols. The exhaust gas generated by the space and directly discharged into the atmosphere can easily cause air pollution and even cause large-scale viral infections. Therefore, this gas needs to be sterilized before being emptied. The utility model patent with patent number: CN220735866U discloses an exhaust gas sterilization device for a medical negative pressure system, which specifically discloses a tank body with a structure that uses a spray component and a circular plate to hedge. High-temperature steam is sprayed into the tank body through the spray component. The circular plate is connected to the air inlet pipe. The circular plate has a hollow structure and air holes are provided on the circular plate. The exhaust gas is discharged into the tank body through the air inlet pipe, the circular plate, and the air holes. The gas flows from bottom to top and the high-temperature steam flows from top to bottom. After the two meet, the high-temperature steam inactivates the pathogens in the exhaust gas at high temperature, and the exhaust gas is discharged after being filtered through a water filter plate. After prolonged use, this type of equipment can cause a small amount of bacteria to accumulate and adhere to the side walls of the tank after being inactivated by high temperature. This increases the viscosity of the tank's inner wall, causing some bacteria to adhere directly to the inner wall. If the bacteria accumulate too much, even after being inactivated, they can still produce a large amount of odor, affecting the exhaust gas purification effect. Utility Model Content

[0003] The technical problem to be solved by the utility model is that inactivated bacteria are easily accumulated in the inactivation tank, and the generated odor affects the purification effect of the tail gas.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a steam high-temperature sterilization device, comprising a tank body, a bucket frame installed under the tank body, a driving assembly arranged in the tank body and the bucket frame, and a scraper assembly sleeved on the driving assembly, the tank body being equipped with an air inlet pipe, an air outlet pipe and an injection pipe port, a brush plate being installed on the inner wall of the tank body, and a water outlet pipe port being opened on the bucket frame, the driving assembly comprising a screw rotatably installed in the tank body and the bucket frame and a bearing seat installed in the tank body, the bearing seat being installed at the bottom of the injection pipe port, one end of the screw extending out of the bucket frame through the water outlet pipe port, and the other end of the screw rotatably inserted into the bearing seat, the scraper assembly comprising a movable sleeve fitted on the screw and a scraper fixedly connected to the movable sleeve, the scraper being able to scrape the surface of the brush plate.

[0005] Furthermore, a plurality of prisms are protruding from the surface of the brush plate, and the plurality of prisms are arranged in parallel along the axial direction of the tank body, and the scraper is inserted into the brush plate.

[0006] Furthermore, the scraper assembly also includes a support column connecting the movable sleeve and the scraper, the scraper is an annular structure, one end of the support column is connected to the movable sleeve, and the other end of the support column is connected to the inner wall of the scraper.

[0007] Furthermore, a bearing ring is installed in the water outlet, and the bearing ring is sleeved on the screw.

[0008] Furthermore, a water ring is installed on the outer side of the bearing ring, and a channel communicating with the outside of the bucket frame is opened in the water ring.

[0009] Furthermore, the driving assembly also includes a driving motor installed below the bucket frame, and the driving motor can change the rotation direction of the screw.

[0010] Furthermore, a nozzle plugging cover is installed below the injection pipe mouth, the bearing seat is fixedly installed on the nozzle plugging cover, and the end of the screw is fixedly inserted into the bearing seat.

[0011] Furthermore, a plurality of nozzles are evenly opened on the circumference of the side wall of the nozzle plugging cover, and the nozzles pass through the nozzle plugging cover and are connected to the interior of the tank body.

[0012] The beneficial effect of the utility model is that the screw is rotated outside the tank body and the bucket frame, driving the movable sleeve on the screw to drive the scraper to move synchronously, and the scraper can scrape and clean the scale on the brush plate, and the scale flows out from the outlet pipe along with the steam condensate. Since the side wall of the brush plate is often scraped and cleaned by the scraper, the scale on the brush plate is difficult to accumulate, thereby avoiding the accumulation of inactivated bacteria in the tank and avoiding the influence of odor on the exhaust gas purification effect.

DETAILED DESCRIPTION

[0021] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0022] like Figures 1 to 6 As shown, this embodiment provides a steam high-temperature sterilization device, comprising a tank body 10, a bucket frame 20 mounted below the tank body 10, a drive assembly 30 disposed within the tank body 10 and the bucket frame 20, and a scraper assembly 40 sleeved on the drive assembly 30. Steam inactivation of exhaust gas can be completed within the tank body 10 and the bucket frame 20. After prolonged use, the drive assembly 30 drives the scraper assembly 40 to move along the sidewalls of the tank body 10. The scraper assembly 40 scrapes and cleans the sidewalls of the tank body 10, and the scraped impurities flow out through the bottom of the bucket frame 20.

[0023] like Figure 1 and Figure 2 As shown, the tank body 10 is externally mounted with several legs 110, and the bucket frame 20 is positioned between the legs 110. The legs 110 support the tank body 10 and the bucket frame 20. An air inlet pipe 120 and an air outlet pipe 130 are also mounted on the sidewalls of the tank body 10. The air inlet pipe 120 is located on the end of the tank body 10 near the legs 110, while the air outlet pipe 130 is located on the end of the tank body 10 away from the legs 110. The air inlet pipe 120 connects to the exhaust system within the enclosed space, while the air outlet pipe 130 connects to the outside atmosphere. The air inlet pipe 120 injects the gas to be inactivated into the tank body 10. After the gas is steam-inactivated within the tank body 10, it is discharged through the air outlet pipe 130.

[0024] An injection nozzle 140 is installed at the top of the tank body 10, and a water outlet nozzle 210 is installed at the bottom of the bucket frame 20. The inlet nozzle 140 can inject high-pressure, high-temperature steam into the tank body 10. Preferably, a nozzle plug 150 is installed below the injection nozzle 130. The nozzle plug 150 is arranged in the tank body 10. A plurality of nozzles 151 are evenly distributed on the side wall of the nozzle plug 150 in a circumferential direction. The nozzles 151 pass through the nozzle plug 150 and are connected to the interior of the tank body 10. After entering the tank body 10, the steam diffuses. In the tank body 10, the steam and gas fully contact each other. The high temperature and high humidity characteristics of the steam can kill the microorganisms in the gas, completing the steam inactivation. As the steam diffuses in the tank, due to the weakening of the ambient pressure, the steam partially condenses. The condensed water adsorbs the inactivated microbial impurities onto the inner wall of the chamber. A brush plate 160 is fixedly mounted on the side wall of the tank body 10. Steam condensate flows downward along the brush plate 160 and is collected in the middle of the bottom of the bucket frame 20. Preferably, a plurality of prisms 161 are protruding from the inner wall of the brush plate 160. The plurality of prisms 161 are arranged parallel to the axis of the tank body 10. A through hole is opened in the middle of the bottom of the bucket frame 20, and the condensate flows out from the water outlet 210 of the bucket frame 20.

[0025] like Figure 1 、 Figure 3 as well as Figure 6 As shown, the driving assembly 30 includes a driving motor 310 installed below the bucket frame 20 , a screw 320 set on the rotating shaft of the driving motor 310 , and a bearing seat 330 installed on the top of the tank body 10 .

[0026] The drive motor 310 is a bidirectional servo motor. The shaft of the drive motor 310 and the end of the screw 320 are preferably connected by a spline connection. The drive motor 310 can change the direction of rotation of the screw 320. One end of the screw 320 extends externally through the water outlet port 210 at the bottom of the bucket frame 20. The other end of the screw 320 is rotatably connected to the top plate of the tank body 10. The drive motor 310 rotates the screw 320 from outside the tank body 10. The bearing seat 330 is fixedly mounted on the nozzle plug 150, and the end of the screw 320 is fixedly inserted into the bearing seat 330. When the drive motor 310 is activated, the screw 320 rotates relative to the bearing seat 330 within the tank body 10.

[0027] like Figure 6 As shown, the scraper assembly 40 includes a movable sleeve 410 fitted on the screw 320 , a support column 420 mounted on the side wall of the movable sleeve 410 , and a scraper 430 fixed to the end of the support column 420 .

[0028] The movable sleeve 410 is sleeved on the screw 320 in a threaded manner. When the screw 320 rotates, the movable sleeve 410 can move up and down along the screw 320 under the drive of the thread. The end of the support column 420 is fixedly mounted on the outer wall of the movable sleeve 410. The scraper 430 has an annular structure. The end of the support column 420 is fixed to the end of the scraper 430. The outer wall of the scraper 430 can scrape the surface of the brush plate 160. The outer wall of the scraper 430 and the prism 161 of the brush plate 160 are correspondingly arranged. The outer wall of the scraper 430 is sleeved on each prism 161. When the scraper 430 moves up and down under the drive of the screw 320 and the movable sleeve 410, the scraper 430 can move relative to the brush plate 160. The scraper 430 scrapes and cleans the prisms and the liquid remaining between the prisms. The condensed water pushed and brushed between the prisms 161 flows along the gap to the bucket frame 20.

[0029] Preferably, a bearing ring 220 is also installed in the water outlet pipe 210 of the bucket frame 20, and the bearing ring 220 is sleeved on the screw 320. A water ring 230 is installed on the outside of the bearing ring 220. The water ring 230 also has a channel connected to the outside of the bucket frame 20, and the condensed water in the bucket frame 20 can be discharged through the channel.

[0030] When in use, exhaust gas is injected into the tank body 10 through the air inlet pipe 120, and high-pressure steam is injected into the tank body 10 through the injection nozzle 140. The high-pressure steam is evenly distributed at various positions in the tank body 10 under the distribution of the nozzle 151. The high-pressure and high-temperature steam and the treated exhaust gas are fully in contact in the tank body 10, thereby achieving full inactivation of the exhaust gas. The inactivated exhaust gas is discharged from the exhaust pipe 130 to the next workstation. After the high-temperature and high-pressure steam is ejected from the nozzle 151, it is mixed with the inactivated microorganisms to form scale and condense on the brush plate 160. The remaining steam mixed with the exhaust gas is discharged synchronously from the exhaust pipe 130, while another part of the steam condenses on the brush plate 160, flows along the prism 161 of the brush plate 160 to the bucket frame 20, and is discharged from the channel of the water ring 230 after being collected in the bucket frame 20. When excessive scale accumulates on the brush plate 160, the drive motor 310 is activated, causing the screw 320 at the end of the motor shaft to rotate synchronously, and the screw 320 rotates in the bearing seat 330. The movable sleeve 410 on the screw 320 moves axially, and the movable sleeve 410 can move through the support column 420 to drive the scraper 430 to move on the brush plate 160. The scraper 430 can scrape the prisms 151 on the brush plate 160 until the scale on the brush plate 160 is cleaned, reducing gas pollution in the tank body 10 and improving exhaust gas purification efficiency.

[0031] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
