Technical Field

[0001] The utility model relates to the technical field of exhaust equipment, in particular to livestock breeding exhaust equipment that can be adjusted at multiple angles. Background Art

[0002] In livestock farms, the residue and accumulation of animal manure will cause the ammonia concentration in the breeding shed to rise rapidly, and there is a chance of producing methane, which will not only affect the healthy growth of animals, but also have a negative impact on the health of farm workers, requiring regular ventilation.

[0003] In current livestock farms, negative pressure fans are usually used for exhaust. Negative pressure exhaust fans are installed on the outer wall of the breeding shed, and air intake windows are opened on the outer wall on the other side. The negative pressure fans draw air out of the breeding shed, and the outside space enters from the air intake windows. There are some functional deficiencies in actual use, and there is room for improvement. For example, the position of the negative pressure fan is fixed, and there is only one air outlet for exhaust, and the position and angle are relatively fixed. In breeding sheds with a large depth and a long shed type, exhaust can only be achieved by installing multiple fans. The installation cost is high, and the walls of the breeding shed need to be modified, which is more troublesome. In addition, the exhaust and suction positions of the fans are limited to the fan installation location. There are many waste gases in the breeding shed, including biogas, carbon dioxide, etc., and waste gases of different densities have different suspension heights, making it difficult to achieve multi-angle targeted suction. The function of adjusting the suction direction at multiple angles is not available.

[0004] Now, a new type of livestock breeding exhaust equipment with multi-angle adjustment is proposed to solve the above problems. Utility Model Content

When in use, the exhaust pipe and blower pipe are fixed on the wall of the breeding shed through a fixing frame, and the negative pressure fan and blower are installed on the outer wall of the breeding shed. The negative pressure fan discharges the air in the exhaust pipe to the outside, and the exhaust pipe forms a negative pressure suction force, which sucks the air in the breeding shed along the steering sleeve, rubber lining tube, connecting sleeve and air suction port, and discharges it from the negative pressure fan.

At the same time, the connecting sleeve can be rotated along the outside of the air suction port, so that the opening of the steering sleeve can be adjusted left and right. The rubber sleeve can play a damping role while ensuring the sealing, so that the angle between the air suction port and the connecting sleeve is fixed. By adjusting the suction direction, different gases and different breeding environments can be suctioned and discharged in a targeted manner, realizing the function of adjusting the suction direction at multiple angles.

[0017] (2) By providing an air outlet pipe, electric heating wire, flange ring and mounting screw holes, when exhausting in summer, the blower is started synchronously, and air is continuously blown into the breeding shed through the blast pipe and the air outlet pipe to ensure sufficient air exchange. When exhausting in winter, the electric heating wire in the air outlet pipe is connected to electricity, and the air is heated by the electric heating wire when flowing through the air outlet pipe, and hot air is blown out to avoid heat loss in the breeding shed. The flange ring and mounting screw holes facilitate the disassembly and assembly of the air outlet pipe, thereby realizing the function of air heating;

[0018] (3) By providing an external thread placement tube, a water-absorbing resin rod and an internal thread mounting ring, when in use, the air in the breeding shed is discharged along the exhaust pipe. The circulating air is rich in a large amount of water. The water-absorbing resin rod in the external thread placement tube can quickly capture water molecules in the air, so that the inside of the exhaust pipe remains dry. When the water-absorbing resin rod needs to be replaced, it is only necessary to rotate the external thread placement tube and remove it from the internal thread mounting ring, and then the internal water-absorbing resin rod can be taken out for replacement, thereby realizing the dehumidification function of the exhaust duct.
