6.Do a good job of checking
Before opening the wet curtain, various inspections should be done: first, check whether the longitudinal fan is running normally; then check whether there is dust or sediment deposition on the wet curtain fiber paper, and check whether the water collector and water pipe are blocked; finally, check whether the water pump enters the water. Whether the filter screen at the place is damaged, and whether there is water leakage in the entire water circulation system. If no abnormality is found in the above inspection, the normal operation of the wet curtain system can be guaranteed.
7. Moderately open the wet curtains
The wet curtain cannot be opened too much during use, otherwise it will waste a lot of water and electricity resources, and even affect the healthy growth of chickens. When the temperature of the chicken house is high, the wind speed of the chicken house is first increased by increasing the number of longitudinal fans turned on, so as to achieve the purpose of reducing the temperature of the chickens. If all the fans are turned on, the house temperature is still 5°C higher than the set temperature, and when the chickens are gasping for breath, in order to avoid the further increase of the house temperature and cause severe heat stress on the chickens, it is necessary to turn on the humidifier at this time. Curtain to cool down.
Under normal circumstances, the temperature of the chicken house cannot be lowered immediately after the wet curtain is opened (the change of the temperature of the chicken house should fluctuate within the range of 1°C up and down). or respiratory symptoms. When opening the wet curtain for the first time, it is necessary to turn off the water pump when it is not completely wetted. After the fiber paper is dry, open the wet curtain to gradually increase the wetted area, which can prevent the temperature in the house from dropping too low and prevent the chickens from cooling down. stress.
When the wet curtain is opened, the humidity of the chicken house is often increased. When the external humidity is not high, the cooling effect of the wet curtain is better. However, when the humidity increases to more than 80%, the cooling effect of the wet curtain is minimal. If the wet curtain continues to be opened at this time, it will not only fail to achieve the expected cooling effect, but also increase the difficulty of cooling the chicken body due to the high humidity. Groups cause a greater stress response. Therefore, when the external humidity exceeds 80%, it is necessary to close the wet curtain system, increase the ventilation volume of the fan and increase the wind speed of the chicken house, and try to reduce the perceived temperature of the chicken group to achieve the air cooling effect. When the external humidity is lower than 50%, try not to open the wet curtain, because the air humidity is too low, and the water vapor evaporates too quickly after passing through the wet curtain, the temperature of the chicken house drops too much, and the chickens are prone to cold stress.
In addition, the use of wet curtains should be minimized for small-day-old chickens to avoid air-cooling stress caused by large temperature differences in the house.
8 .Pad water management
The lower the temperature of the circulating water in the wet pad system, the better the cooling effect. It is recommended to use deep well water with a lower temperature. However, the water temperature will rise after several cycles, so it is necessary to replenish new deep well water in time. In the hot summer, the conditional chicken farms can add ice cubes to the circulating water to reduce the water temperature and ensure the cooling effect of the wet curtain.
If the wet curtain has not been used for a long time, when it is opened again, in order to prevent the bacteria attached to it from being sucked into the house, disinfectants should be added to the circulating water to kill or reduce pathogenic microorganisms on the wet curtain and reduce the probability of disease in the flock. . It is recommended to use organic acid preparations for the first disinfection of wet curtains, which not only play a role in sterilization and disinfection, but also eliminate calcium carbonate on the fiber paper.
9. Timely maintenance of wet pad device
During the operation of the wet curtain, the gaps of the fiber paper are often blocked by dust in the air or algae and impurities in the water, or the fiber paper is deformed without an oil layer applied, or the wet curtain is not air-dried after being used or is not used for a long time, resulting in the surface of the fiber paper. Fungal accumulation. Therefore, after the wet curtain is opened, it should be stopped for at least half an hour every day, and the fan behind it should be kept running normally, so that the wet curtain is completely dried, so as to prevent algae from growing on the wet curtain, and avoid blockage of filters, pumps and water pipes, etc., so as to prolong the Wet curtain service life. In order to ensure the normal operation of the wet curtains, it is recommended to clean the filter once a day, check and maintain the wet curtain 1-2 times a week, and remove the leaves, dust and moss and other debris attached to it in time.
10 .Do a good job of protection
When the summer is over and the weather turns cooler, the wet curtain system will be inactive for a long time. In order to ensure the use effect of the wet curtain system in the future, a comprehensive inspection and maintenance must be carried out. First, drain the circulating water in the pool and water pipes for water storage, and seal it tightly with a cement cover or plastic sheet to prevent external dust from falling into it; at the same time, remove the pump motor for maintenance and seal it up; in order to prevent the occurrence of wet curtain fiber paper Oxidation, wrap the entire wet curtain tightly with plastic cloth or color strip cloth. It is recommended to add cotton pads inside and outside the wet curtain, which can not only better protect the wet curtain, but also prevent cold air from entering the chicken house. It is best to install automatic roller shutters in large-scale chicken farms, which can be closed and opened at any time to strengthen the protection of wet curtains.
