Description

Technical Field

[0001] The utility model relates to the technical field of farm disinfection, in particular to a ventilation and disinfection device for a farm. Background Art

[0002] With the continuous development of livestock and poultry farming in my country, piggery farms have formed a large-scale operation. Under normal circumstances without an epidemic, the concentration of bacteria or viruses in the air of a closed piggery farm is 500-1100 times that of the air outside the farm, and the concentration of bacteria in the air of a semi-open piggery farm is 110-580 times that of the air outside the farm. Among these bacteria, 1% are pathogenic microorganisms, which float in the air and are easily inhaled into the lungs by pigs to cause infection. Once an epidemic occurs, it is highly contagious and spreads very quickly. The concentration of pathogenic microorganisms in the air inside and outside the piggery farm is even higher, which may cause all poultry and livestock in the farm to be harmlessly treated, causing serious economic losses to the operator. Therefore, in order to prevent the spread of the epidemic, disinfection and ventilation in the farm are the top priorities of work. The existing disinfection method is generally to disinfect by spraying disinfectant or using a high-pressure ozone ammonia removal disinfector. This method is generally implemented when there are no poultry and livestock in the farm or the poultry and livestock are driven away regularly. Disinfection is not possible during the breeding period. Although ventilation and regular disinfection are maintained at ordinary times, the concentration of bacteria in the air will still gradually increase, increasing the chance of infection.

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] Example: Please refer to Figure 1-2A ventilation and disinfection device for a farm includes a ventilation structure shell 1 and a disinfection component located inside the ventilation structure shell 1. The disinfection component includes a primary filter 2, a micro-electrostatic air purification module 3 and an ultraviolet disinfection module arranged in sequence along the air flow direction. The primary filter 2 performs primary filtration to remove larger particles in the air. The micro-electrostatic air purification module 3 is a prior art that can exert a huge suction force on particles in the air to produce a dust removal and purification effect. It can achieve a microbial purification rate of more than 85% at a low wind speed of about 2.5m / s, and achieve high-efficiency filtration under extremely low wind resistance conditions. The ultraviolet disinfection module includes an ultraviolet lamp module 4 and two shading plates 6. The ultraviolet lamp module 4 includes a support plate 7 and two groups of ultraviolet lamp tubes 8. The two groups of ultraviolet lamp tubes 8 are installed on both sides of the support plate 7. The two shading plates 6 are installed on both sides of the ultraviolet lamp module 4. The shading plates 6 can concentrate the ultraviolet rays emitted by the ultraviolet lamp tubes 8 without dispersing them, thereby improving the disinfection effect of ultraviolet rays and preventing ultraviolet rays from leaking out. At the same time, a certain gap is left between the two sides of the support plate 7 and the two sides of the shading plates 6 and the inner wall of the ventilation structure shell 1 to ensure air circulation in the ventilation structure shell 1. The wavelength of ultraviolet rays emitted by the ultraviolet lamp tubes 8 is 254nm. Ultraviolet light with a wavelength of 254nm can act on DNA and RNA, and on thymine to form dimers, thereby preventing genetic material replication, killing microorganisms, and eliminating cross-infection risks. A fan 5 is installed at one end of the ventilation structure shell 1. The fan 5 is located on the side of the ultraviolet disinfection module away from the micro-static air purification module 3. The fan 5 is used to introduce air with bacteria into the disinfection component for disinfection and sterilization, and then introduce it into the farm to reduce the concentration of microorganisms in the air in the farm, so as to achieve ventilation during the breeding period. At the same time, the efficiency and effect of disinfection are improved through the front-stage filtration and the rear-stage disinfection and sterilization, thereby reducing the concentration of bacteria in the air and reducing the probability of infection. A water curtain 11 is installed between the ultraviolet disinfection module and the fan 5 in the ventilation structure shell 1. The water curtain 11 is used to cool the farm when the weather temperature is high. A waterproof shutter 9 is installed at one end of the ventilation structure shell 1 away from the fan 5 to prevent rain from spilling into the ventilation structure shell 1. A protective net 10 is installed at the air input end of the primary filter 2 in the ventilation structure shell 1 to prevent leaves, birds and other debris from flying into the ventilation structure shell 1. The cross section of the ventilation structure housing 1 between the water curtain 11 and the fan 5 is tapered, so that the air after disinfection and sterilization is concentrated and quickly enters the farm through the fan 5. The bottom ends of the primary filter 2, the micro-electrostatic air purification module 3 and the ultraviolet disinfection module are all installed in the ventilation structure housing 1 through the plug-in structure 12. The plug-in structure 12 includes a fixing frame. The primary filter 2, the micro-electrostatic air purification module 3 and the ultraviolet disinfection module can be respectively embedded in the fixing frame for fixing, which is convenient for disassembly, assembly, cleaning and maintenance.An opening is provided at the top of the ventilation structure housing 1 , and a sealing cover 13 is hinged at the top of the ventilation structure housing 1 . The sealing cover 13 cooperates with the opening to facilitate installation and maintenance of components in the ventilation structure housing 1 .

[0022] The working principle of this embodiment is as follows: waterproof shutters 9, protective nets 10, primary filter nets 2, micro-electrostatic air purification modules 3, shading plates 6, ultraviolet lamp modules 4, shading plates 6 and fans 5 are installed in sequence along the air flow direction in the ventilation structure shell 1; when in use, under the power of the fan 5, the air containing bacteria first passes through the waterproof shutters 9 and the protective nets 10 to prevent leaves and other debris from following the wind flow into the ventilation structure shell 1, and then passes through the primary filter net 2 for primary filtration to remove larger particles; then passes through the micro-electrostatic air purification module 3 for dust removal and purification, and realizes efficient filtration under extremely low wind resistance conditions; then passes through the ultraviolet disinfection module for ultraviolet killing, which can efficiently kill microorganisms, and finally enters the farm through the fan 5 to reduce the concentration of microorganisms in the air in the farm, and works in this way.
