Ventilation system for pig breeding farm

Abstract

The invention provides a ventilation system for a pig breeding farm, and particularly relates to the field of ventilation equipment for pig breeding farms. The ventilation system is characterized in that an air inlet is formed in passages in a breeding air chamber, and the air inlet is closed by a screen plate; a hollow air chamber is formed below the air inlet and communicates with the air inlet, air is blown into the air chamber through a plurality of air blowers, and the air enters the breeding chamber through the air inlet provided with the screen plate; the ventilation system is arranged at the bottom of the breeding chamber, does not occupy the breeding space, blows out air from bottom to top through air inlet devices, enables the air in the breeding chamber to be replaced quickly, enables the air at the bottom of the breeding chamber to be replaced more effectively through vertical ventilation, and improves the ventilation efficiency of the breeding chamber. In order to maintain the air chamber to be clean, flushing is performed through a flushing port and scattered water channels, the water flow flows through the bottom of the air chamber to take away impurities such as fine gravels, good ventilation and cleanness are guaranteed, the bottom surface of the air chamber is cleaned by the water flow under the condition that excessive water is not used, water consumption is reduced, and economy is achieved.

Description

technical field [0001] The invention relates to the field of ventilation equipment for pig farms, in particular to a ventilation system for pig farms. Background technique [0002] Pork is a necessary meat in the daily diet of the people. Pig breeding provides the source of national meat products. Pig farms are the main pork production places. Pig farms are large in size and large in output, which is convenient for centralized management; Pig farms are generally built as large-scale indoor facilities. If ventilation is not done well, the indoor environment cannot be guaranteed, which will affect the health of management personnel. Pigs are also prone to illness and infection, leading to bad consequences. [0003] General pig farm ventilation equipment is installed on the side wall of the breeding room, and the air exchange between the house and the outside is directly performed through a high-power fan. The indoor air circulation brought by the ventilation equipment on the s...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides a ventilation system for pig farms, which solves the problems in the prior art that the air exchange in the ventilation system of pig farms has low air replacement efficiency due to horizontal air flow. Low, poor technical issues
