Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture disinfection, and particularly to a microbial aerosol disinfection device. Background Art

[0002] An aerosol refers to tiny particles suspended in the atmosphere. It is a colloidal dispersion system formed by solid or liquid small particles dispersed and suspended in a gas medium. Common aerosols in life include: smoke, haze, fermentation, aerosol perfumes, pesticides, etc. In the air of a farm, there will be viruses, bacteria, fungi, and other by-products suspended. These microorganisms suspended in the air form microbial aerosols. In a humid, animal-dense, and enclosed breeding environment, microbial aerosols are likely to cause disease transmission.

[0003] Currently, in farms, disinfection is mainly carried out by spraying disinfectant and ultraviolet irradiation. The volume of the sprayed disinfectant droplets is relatively large, the residence time of the disinfectant droplets in the air is short, and the contact area with the air is limited. Moreover, ultraviolet light can only disinfect the directly irradiated area. Since there are many breeding equipment and tools in the farm, there are areas that cannot be irradiated by light, which are likely to leave disinfection dead corners. Therefore, both of these methods have limited disinfection effects on the microbial aerosols suspended in the air and cannot deodorize the odors in the farm.

[0004] Therefore, a microbial aerosol disinfection device that solves the above problems is needed. Summary of the Invention

[0005] The present invention provides a microbial aerosol disinfection device, which realizes the automatic preparation, injection of micro-nano bubbles, and atomization of the disinfectant. Under the dual action of micro-nano bubbles and droplets, the disinfectant is fully contacted with the air in the farm, improving the disinfection effect of microbial aerosols in the air, reducing the risk of disease transmission, and improving the air quality of the farm.

[0006] The technical solution of the present invention is realized as follows: A microbial aerosol disinfection device includes a frame, on which a disinfectant preparation tank body, a microbial aerosol disinfection tank body, and a filtration tank body are sequentially connected in communication. The microbial aerosol disinfection tank body and the filtration tank body are jointly connected in communication with a waste liquid collection tank body; The disinfectant preparation tank body is provided with a disinfection powder feeding port, a liquid inlet, and a disinfectant liquid discharge port. A micro-nano bubble generator is arranged inside the disinfectant preparation tank body. A disinfection powder unpacking and feeding assembly is arranged at the disinfection powder feeding port. A spherical gas tank is arranged between the disinfectant liquid discharge port and the microbial aerosol disinfection tank body. An inlet liquid atomizing pipe and a gas-liquid mixing spray pipe are oppositely arranged on the spherical gas tank. An air inlet gap is arranged between the inlet liquid atomizing pipe and the gas-liquid mixing spray pipe. An air storage tank is arranged on the frame, and the air storage tank is communicated with the spherical gas tank. The microbial aerosol disinfection tank body is connected with an air purification assembly.

[0007] As a preferred technical solution, the micro-nano bubble generator includes a hollow rotating shaft rotatably installed inside the disinfectant preparation tank body. A plurality of ceramic membrane discs are arranged on the hollow rotating shaft. The inside of each ceramic membrane disc is communicated with the hollow rotating shaft. A plurality of nano holes are arranged on each ceramic membrane disc. The hollow rotating shaft is communicated with the air storage tank.

[0008] As a preferred technical solution, a nozzle is fixedly installed inside the inlet liquid atomizing pipe. The diameter of the nozzle gradually decreases from both ends to the middle. The disinfectant liquid discharge port is communicated with a water pump, and the liquid outlet of the water pump is communicated with the nozzle.

[0009] As a preferred technical solution, the gas-liquid mixing spray pipe includes a mixing section with a gradually decreasing inner diameter and an expanding spray section with a gradually increasing inner diameter. The small-diameter end of the mixing section is connected to the small-diameter end of the expanding spray section. The large-diameter end of the mixing section is oppositely arranged with the free end of the nozzle. The large-diameter end of the expanding spray section extends into the microbial aerosol disinfection tank body.

[0010] As a preferred technical solution, a sliding unpacking frame is slidably installed on the frame in the vertical direction. The sliding unpacking frame is connected with an unpacking frame driving assembly. A horizontally arranged packaging box placing disc is rotatably arranged on the sliding unpacking frame. A plurality of limiting grooves for limiting the disinfection powder packaging boxes are arranged on the packaging box placing disc. The limiting grooves are arranged in pairs and extend along the radial direction of the packaging box placing disc.

[0011] As a preferred technical solution, the disinfection powder packaging box includes a powder loading box body. The mouth part of the powder loading box body extends horizontally outward to form a limiting edge. A sealing film is arranged at the limiting edge. The limiting edge is arranged in the corresponding limiting groove.

[0012] As a preferred technical solution, the disinfection powder unpacking and feeding assembly includes a feeding pipe fixedly installed at the top of the disinfectant solution preparation tank along the vertical direction. The feeding pipe is communicated with the disinfectant solution preparation tank and is arranged below the packaging box placement tray. Two unpacking blades for breaking the sealing film are fixedly installed at the upper end of the feeding pipe. A circular valve plate is rotatably installed in the feeding pipe, and the circular valve plate is connected with a valve plate driving assembly.

[0013] As a preferred technical solution, a reversing pipe is vertically arranged in the filter tank. A spiral blade is fixedly installed on the outer wall of the reversing pipe. The upper end of the reversing pipe is communicated with the exhaust port of the filter tank. The air inlet of the filter tank is communicated with the microbial aerosol disinfection tank. A liquid separation plate is fixedly installed on the inner wall of the filter tank, and the liquid separation plate is arranged below the reversing pipe.

[0014] By adopting the above technical solutions, the beneficial effects of the present invention are as follows: Since the microbial aerosol disinfection equipment includes a microbial aerosol disinfection tank, during the use of the equipment, through the cooperation of the disinfection powder unpacking and feeding assembly and the micro-nano bubble generator, the automatic preparation of the disinfectant solution and the injection of micro-nano bubbles are realized. The disinfectant solution containing micro-nano bubbles enters the nozzle under the transportation of the water pump. After the disinfectant solution is sprayed out of the nozzle and enters the mixing section, the pressure of the disinfectant solution decreases at this time, forming a low-pressure area. The negative pressure generated in the low-pressure area enables the ozone in the spherical gas tank to enter the mixing section from the air inlet gap. Under the action of the high-speed spraying and turbulence of the disinfectant solution in the mixing section, the disinfectant solution is broken into fine droplets. After the droplets enter the expanding spray section, the collision and energy transfer between the fluids further refine the droplets. After the refined droplets are sprayed out, they are in full contact with the air in the microbial aerosol disinfection tank. The disinfectant solution disinfects the microbial aerosol in the air, and the air after disinfection is filtered by the filter tank to filter the disinfectant solution droplets carried in the air, and then discharged, thereby realizing the disinfection of the air in the breeding farm.

[0015] In the present invention, the automatic preparation of the disinfectant solution, the injection of micro-nano bubbles and the atomization are realized. Under the dual action of the micro-nano bubbles and the droplets, the disinfectant solution is in full contact with the air in the breeding farm, improving the disinfection effect of the microbial aerosol in the air, reducing the risk of disease transmission, and improving the air quality of the breeding farm.

[0016] Since the microbial aerosol disinfection equipment includes a micro-nano bubble generator, during the preparation of the disinfectant solution, micro-nano bubbles are injected into the disinfectant solution. At the same volume, the specific surface area of micro-nano bubbles is larger than that of macro bubbles, thus increasing the contact area between gas and water, enabling the disinfection powder to disperse and dissolve more quickly and better in water. Under the action of surface tension in water, the internal pressure of micro-nano bubbles is higher than the external liquid pressure. This self-pressurizing effect makes the gas in the bubbles more easily dissolve into water, promoting the dispersion and dissolution of the disinfection powder. The surface of micro-nano bubbles is negatively charged, forming a stable double electric layer. This charged property can prevent the aggregation of disinfection powder particles and make them disperse more evenly in water. Combined with the high-speed stirring of the ceramic membrane disk for water, the dissolution effect of the disinfection powder in water is improved.

[0017] During the disinfection process, due to the extremely small size of micro-nano bubbles and their good suspension and dispersion properties, the disinfectant solution can stay in the air for a longer time. Atomization enables the disinfectant droplets to be more evenly distributed in the air, so that the disinfectant can fully contact the microbial aerosol, improving the disinfection effect.

[0018] Since the disinfectant solution preparation tank body includes a disinfection powder unpacking and feeding component, there are problems such as the disinfection powder contacting the air and becoming ineffective, the dosage of the disinfection powder being uncontrollable, and insufficient stirring during the manual preparation of the disinfectant solution, resulting in a poor disinfection effect of the manually prepared disinfectant solution. In the present invention, the limiting placement and automatic material replacement of the disinfection powder packaging box can be realized through the packaging box placement tray. The cooperation of the sliding unpacking rack and the unpacking blade realizes the breaking of the sealing film. After the sealing film is broken, the disinfection powder in the disinfection powder packaging box falls into the disinfectant solution preparation tank body through the feeding pipe, thus realizing the automatic unpacking and feeding of the disinfection powder packaging box. In the present invention, the disinfection powder is packaged independently and sealed, solving the problems of the disinfection powder contacting the air and becoming ineffective and the dosage of the disinfection powder being uncontrollable. Combined with the stirring of micro-nano bubbles and the ceramic membrane disk, the problem of insufficient dissolution of the disinfection powder in water is solved.

[0019] Since the microbial aerosol disinfection equipment includes a filter tank body, after the disinfected air enters the filter tank body, under the action of the spiral blades, the air forms a rotating eddy current in the filter tank body. This rotational movement generates centrifugal force, throwing the disinfectant droplets carried in the air towards the inner wall of the filter tank body. The disinfection liquid flows downward along the inner wall of the filter tank body and finally converges at the bottom of the filter tank body. The rotating and descending air converges towards the center at the bottom of the spiral blades, forming an upward inner swirl. The gas in the inner swirl continues to rotate and flow upward, and finally is discharged through the reversing pipe. At this time, the liquid droplets in the gas have been separated.
