Description
DESCRIPTION Ventilation System for Pigsty in Cold Region
[0001] The invention relates to the field of livestock and poultry breeding, in particular to a ventilation system for pigsty in cold region.
[0002] The temperature difference between indoor and outdoor of pigsty in cold region 1s large in winter, so it is an extremely important technical means for pig breeding in cold region to keep proper temperature and humidity of pigsty and reduce the concentration of harmful gases. The existing pigsty in cold region generally realizes the heat preservation of pigsty by sealing and installing heating equipment, and reduces the humidity and harmful gas concentration in pigsty by strengthening ventilation. However, the sealing and heat preservation of pigsty in winter are contradictory to reducing the humidity and harmful gas concentration in pigsty, and they often lose sight of one another in production practice, and with the entry of cold air, it is bound to produce air flowing in the pigsty to form cold air, which is easy to cause pigs to catch a cold.
[0003] The present invention mainly solves the technical problem of ventilation existing in the existing pigsty in cold region, thus providing a ventilation system for pigsty in cold region. According to the invention, the heat loss generated by manure fermentation in the water-soaked manure sewage ditch and the heat loss in the process of discharging waste gas can be reduced.
[0004] The above technical problems of the present invention are mainly solved by the following technical scheme.
[0005] A ventilation system for pigsty in cold region comprises pigsty and a ventilation system, wherein the pigsty consists of an insulation layer, a feeding area, a water-soaked manure sewage ditch and a corridor, wherein the insulation layer and the feeding area are located above the ground, and the water-soaked manure sewage ditch is located below the ground. The insulation layer is provided with a skylight, and the feeding area is divided into several feeding units, each feeding unit has an aisle and one to two rectangular herd pig pens, and both sides of the pigsty are provided with a south window and a north window. The ventilation system comprises an air inlet duct and an exhaust duct, wherein the air inlet duct consists of a fresh air fan, a heat conversion device, a temperature control room, an air inlet pipe, a fresh air inlet and a guard plate in turn. The exhaust duct consists of exhaust outlet I, exhaust outlet II, exhaust pipe I, exhaust pipe II, pilot valve, heat conversion device, waste gas treatment room and exhaust fan in turn.
[0006] As a further technical scheme of the present invention, a sealing device and a deodorization device are arranged in the water-soaked manure sewage ditch. The side wall of the water-soaked manure sewage ditch is sequentially provided with an exhaust outlet I and an exhaust outlet II, wherein the exhaust outlet I is located above the sealing device and connected with the exhaust pipe I, the exhaust outlet II is located below the sealing device and connected with the exhaust pipe II, and the exhaust pipe I and the exhaust pipe II are connected with the heat conversion device through the pilot valve. The pilot valve is always communicated with the exhaust pipe I and disconnected from the exhaust pipe II. To discharge harmful gases in the house, only when cleaning up the manure on the sealing device, the pilot valve is turned to the exhaust pipe II before the sealing device is opened, and then disconnected from the exhaust pipe I, so as to discharge harmful gases in the water-soaked manure sewage ditch, so as to avoid harmful gases entering the feeding area during the opening process of the sealing device. After the sealing device is cleaned and closed again, the pilot valve is turned back to the exhaust pipe I and disconnected from the exhaust pipe II.
[0007] As a further technical scheme of the present invention, the sealing device is in a normally closed state, sealing harmful gas generated by manure fermentation in the water-soaked manure sewage ditch, and opening the sealing device regularly through an automatic control system to clean the newly generated manure on the sealing device into the water-soaked manure sewage ditch.
[0008] As a further technical scheme of the present invention, the heat conversion device is located at the bottom of the water-soaked manure sewage ditch, and consists of a waste gas pipe and a fresh air pipe which are sleeved, wherein the waste gas pipe 1s located inside and the fresh air pipe is located outside. The fresh air pipe can recover the heat generated by manure fermentation in the water-soaked manure sewage ditch outward and the heat emitted by the waste gas pipe inward.
[0009] As a further technical scheme of the present invention, the waste gas treatment room is located on the north side of the pigsty, and its height is as high as the lower edge of the north window, so as not to affect the window opening, and the treated gas is discharged through the exhaust fan.
[0010] As a further technical scheme of the present invention, the fresh air ventilator is located in the air inlet chamber on the south side of the pigsty. The fresh air ventilator sends air into the fresh air pipe in the heat conversion device. The fresh air pipe leads the air into the temperature control room, which adjusts the air to the pigsty temperature and then sends the air into the air inlet pipe, and the air enters the pigsty through the fresh air inlet.
[0011] As a further technical scheme of the present invention, a guard plate is installed at the outlet end of the fresh air inlet to adjust the wind direction and avoid discomfort caused by fresh air blowing directly on pigs.
[0012] As a further technical scheme of the present invention, the deodorization device is composed of a hole body, a spring and a baffle, the upper end of the hole body is in a cross frame structure, and under the action of the spring, the baffle and the hole body are in a normally closed state to prevent the gas in the water-soaked manure sewage ditch from diffusing into the pigsty. When the pilot valve turns to the exhaust pipe II, the spring is stretched due to the negative pressure generated in the water-soaked manure sewage ditch, and the baffle separates from the hole body and the gas flows into the water-soaked manure sewage ditch, thus achieving the purpose of deodorization.
[0013] As a further technical scheme of the present invention, the south window, the north window and the skylight of the pigsty are in a closed state in winter, and are only opened as ventilation channels in summer when the temperature is high.
[0014] Compared with the existing ventilation technology in cold region, the present invention can effectively recover the heat lost in pigsty, reduce the diffusion of harmful gases into pigsty, and has the advantages of good heat preservation in pigsty, uniform ventilation, energy saving, high exhaust gas removal efficiency, etc, thus significantly improving the living environment of pigs and reduces the environmental pollution.
