Description

Egg disinfection equipment Technical Field The application relates to the technical field of poultry farming, in particular to egg disinfection equipment. Background The egg is used as a core carrier for poultry breeding, and organic pollutants such as fecal particles, fallen feathers, mucus secretions and the like are easily attached to the surface of the egg in the production process due to contact with a production passage and a breeding environment. If the dirt is not thoroughly cleared, the vertical transmission risk of pathogen penetration into embryo through eggshell micropores is obviously improved, and the reduction of hatchability and the deterioration of health level of young birds are directly caused. The traditional disinfection method adopts a mixed fumigation process of formaldehyde and potassium permanganate for a long time, the process has broad-spectrum sterilization characteristic, but the strong volatility of formaldehyde enables the formaldehyde to be rapidly diffused into the air in the operation process, continuous stimulation is caused to respiratory mucosa of operators, chronic bronchitis, leukemia and other serious health problems can be caused by long-term exposure, meanwhile, formaldehyde residual gas is difficult to thoroughly dissipate in a cultivation environment to form persistent pollution, the subsequent poultry growth and ecological environment are deeply and negatively influenced, and the process is restricted or eliminated by regulations in most regions of the world. Although the conventional spray disinfection technology avoids the problem of residual chemical reagent, the conventional spray disinfection technology is limited by the interaction of the surface tension of liquid and a natural curved surface structure of the hatching egg, so that disinfectant is aggregated to form liquid beads in a convex area of the eggshell, but is difficult to effectively wet in a concave part, dense disinfection dead angles are generated, hidden spots of microorganisms cannot be covered on the whole surface, in addition, the surface water of the hatching egg after spraying is slowly evaporated, residual wet films are easy to adsorb suspended dust Egyptian microorganisms in the air, and secondary pollution risks are induced. The existing ultraviolet disinfection equipment realizes the operation without chemical reagents, but the physical characteristic that ultraviolet rays are transmitted in a linear mode can not penetrate through shadow areas formed by mutually stacking hatching eggs, so that the local microorganism inactivation rate is seriously insufficient, meanwhile, the irradiation mode with fixed dose can not adapt to the sensitivity difference of different eggshell thicknesses and embryo development stages, the structural integrity of eggshell micropores can be damaged by excessive irradiation, the normal development activity of the embryos is inhibited, and the pathogens can not be thoroughly killed due to the insufficient dose. More importantly, the current commercial disinfection equipment generally depends on manual experience to preset operation parameters, so that the real-time image analysis capability is not only lacking to quantify the area ratio of stains, but also the disinfection process cannot be dynamically adjusted according to environmental parameters such as temperature and humidity, disinfectant concentration, ultraviolet intensity and the like, so that eggs with different pollution degrees in the same batch are forced to be subjected to homogenization treatment. For example, highly contaminated eggs remain pathogens due to insufficient disinfection strength, while clean eggs suffer from excessive disinfection damage to the natural protective layer of eggshells. The open loop system lacking the closed loop feedback mechanism completely ignores individual characteristic changes caused by egg sources, batch differences and egg producing ages, so that the disinfection effect presents remarkable fluctuation, and the urgent requirements of modern poultry cultivation on accurate and intelligent disinfection are difficult to meet. Disclosure of Invention In view of the above, the present invention aims to provide an egg disinfection device capable of realizing efficient disinfection of eggs and dynamically adjusting disinfection parameters. The egg disinfection equipment comprises a closed disinfection cabin, wherein the front end in the closed disinfection cabin is provided with a conveying mechanism for cleaning and conveying the surfaces of eggs, the right end in the closed disinfection cabin is provided with a conveying piece for conveying the eggs, the rear end in the closed disinfection cabin is provided with a placing rack for placing the eggs, the inner top surface of the closed disinfection cabin is provided with a compound disinfection system, and the compound disinfection system comprises a high-pressure micro-mist spraying unit for generating disinfection
