The working principle is as follows:
firstly, when the air purification device for the pig breeding colony house is used, the air purification shell 1 is installed on the wall body of the pig breeding colony house, an air inlet 3 formed in the left side of the air purification shell 1 is opposite to the inner side of the pig breeding colony house, then the operation of an ultraviolet lamp 4 and a fan 7 arranged in the air purification shell 1 can be respectively realized through a controller 2 arranged at the right end of the front side of the air purification shell 1, dirty air in the pig breeding colony house can enter the air purification shell 1 along the air inlet 3 to be irradiated and sterilized by the ultraviolet lamp 4 arranged at the upper end of the left side in the air purification shell 1 under the driving of the fan 7, then the air can sequentially pass through a sterilization plate 5 and a filter plate 6 arranged in the middle of the air purification shell 1 to realize secondary sterilization and filtration of impurities in the air, finally, the treated air can be discharged to the outside along an air outlet 8 formed in the right side of the air purification shell 1, and the dirty air in the pig breeding colony house can be rapidly purified through the operation;
secondly, when the air purification device for the pig breeding colony house is used, although the air purification device can well carry out wind adsorption purification on dirty air in the pig breeding colony house, the air purification device carries out purification and filtration through the filter plate, the service life is short, and the air purification device needs to be disassembled and cleaned for many times, so that the filtering and purifying effect is insufficient;
thirdly, the auxiliary discharging and purifying device 9 is arranged on the right side of the air purifying shell 1, namely, the water pump 94 arranged at the lower end inside the water storage tank 93 is operated, so that the water pump 94 transmits the disinfectant stored inside the water storage tank 93, and the disinfectant is sprayed into the processing box 91 through the spray head 95 connected with the lower end of the water pump 94, when air enters the processing box 91 from the exhaust port 8, the air can be sprayed and disinfected, so as to further improve the air purifying effect, and prevent the sterilizing plate 5 and the filter plate 6 from being used for a long time, the purifying effect is reduced, so that the dirty air is fully purified, the external environment is affected, the disinfected air is sprayed inside the processing box 91, the safe discharging can be realized along the air outlet 92 arranged on the right side of the processing box 91, and the advantage of air auxiliary spraying and disinfecting treatment is achieved;
fourthly, in order to realize efficient use of disinfection powder when disinfection water is configured, a quantitative putting component 96 is arranged at the upper end of the left side of a water storage tank 93, namely a timing cylinder 962 arranged in the quantitative putting component 96 is operated, the timing cylinder 962 firstly realizes pushing of a swinging plate 963 in a sliding and inserting mode at the right side and inclines the swinging plate 963, so that the upper end is connected with a moving frame 964 in a sliding mode and moves to the left, when a through hole 965 is formed at the lower end of the right side of the moving frame 964 and is opposite to a vertical groove formed at the right side inside the storage tank 961, putting movement of the powder can be realized, the powder drops into the water storage tank 93, in the left moving process of the moving frame 964, the lower end of the left side of the moving frame 964 is connected with a pressure spring 966, elastic pull-back matching can be realized, the left moving efficiency of the moving frame 964 is improved, when the timing cylinder 963 is pulled to the left side, the swinging plate 963 pushes the moving frame 964 to move to the moving frame 962, so that the storage tank 961 can be sealed again, further sealing can be stopped from transmission, and the quantitative putting of the powder can be used in a reciprocating mode, thereby ensuring the advantages of the powder can be fully used;
fifthly, in order to further improve the usability of the auxiliary discharge purification apparatus 9, the intermittent change of the water flow sprayed by the spray head 95 is changed by arranging the adjusting component 97 at the upper right end inside the treatment tank 91, that is, by operating the driving motor 972 arranged at the left side inside the housing 971, the driving motor 972 drives the rotating plate 973 connected to the front side clockwise to rotate, at first, the lower front end of the rotating plate 973 pushes the blocking plate 975 whose lower end is attached to the left side, so that the left side inclined part of the blocking plate 975 is opposite to the lower end of the spray head 95, when the water flow sprayed by the spray head 95 impacts the blocking plate 975, the water flow can be sprayed to the left side, and when the rotating plate 973 rotates clockwise to contact the auxiliary plate 974 arranged opposite to the right side, the auxiliary plate 974 can be pushed counterclockwise, so that the auxiliary plate 974 pushes the blocking plate 975 to the lower end to move to the right side, so as to release the blocking action of the blocking plate 95, and further, the intermittent movement of the blocking plate 975 can realize the auxiliary change of the spray direction of the spray head 95, thereby improving the disinfection effect of the subsequent air, and further improving the intermittent disinfection effect of intermittent treatment, and improving the intermittent treatment effect of intermittent treatment.
The utility model provides an air purification device of pig breeding colony house, through having set up supplementary emission purifier 9, at storage water tank 93, water pump 94 and shower nozzle 95 cooperate down, can disinfect water spray the processing activity to the air, thereby the advantage of supplementary disinfection processing that sprays of air has been reached, subassembly 96 is put in to ration having set up in storage water tank 93 left side upper end, at timing cylinder 962, swing board 963 and pressure spring 966 cooperate down, can drive and remove about the 964 intermittent type of removal frame, make the inside powder of storage case 961 pass opening 965, stabilize quantitative input and use, thereby the advantage of disinfection powder ration input use has been reached, and set up adjusting part 97 in the inside upper end in treatment case 91 right side, under board 973 and accessory plate 974 normal running fit change, can intermittently push barrier 975, it changes to spray the direction to disinfect water, thereby it sprays the direction intermittent type regulation change to have reached the disinfection water, the improvement sprays the advantage of treatment effect.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described above, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
