Negative pressure dust fall fresh air system for hatchling room

Abstract

The invention discloses a negative pressure dust fall fresh air system for a hatchling room. The negative pressure dust fall fresh air system for the hatchling room comprises a dust fall system for atomizing and spraying the interior of the hatchling room and an air exhaust system for adjusting the pressure intensity in the hatchling room, wherein the air exhaust system comprises an air exhaust fan for driving one or more hatchling machines installed in the hatchling room to update air and maintain the pressure intensity in the hatchling room, and a controller for driving and adjusting the rotating speed of the air exhaust fan; and the controller is connected with a PLC logic editor used for editing and setting control logic of the controller, and a pressure sensor arranged in the hatchling room and used for collecting air pressure intensity in the hatchling room and transmitting the air pressure intensity to the controller. According to the negative pressure dust fall fresh air systemfor the hatchling room, the negative pressure value can be set according to the batch of hatching eggs in the hatchling room and the actual requirement, accurate control is realized, and the adjustment of the negative pressure value in the hatchling room can be realized according to the hatching of a plurality of hatchling machines and different batches.

Description

technical field [0001] The invention relates to the technical field of hatching, in particular to the technical field of hatching devices for chickens and ducks, and in particular to a negative-pressure dust-reducing fresh air system for hatching rooms. Background technique [0002] With the advancement of science and technology, the market's demand for egg-laying poultry meat is increasing day by day. The hatching, breeding and sales of egg-laying poultry have already been batched, scaled and standardized. In order to incubate poultry more scientifically and efficiently, from traditional lighting and heating to professional incubators, and then from incubators to current hatchers. Using scientific and technological equipment to precisely control the temperature, it is possible to incubate egg-laying poultry such as chickens and ducks with high efficiency and high survival rate. [0003] However, to this day, for the hatching production of chicks and ducklings, it is not on...

Problems solved by technology

[0004] In order to solve the problem of insufficient ventilation in the existing technology, the negative pressure value will be insufficient. At the same time, when different batches of hatchers are hatched, the waste gas in the hatching room cannot be discharged in time, so that the subsequent hatched chicks and ducklings are prone to diseases. ; If the negative pressure value is too high due to excessive ventilation, it is easy to draw out the heat-preserving hot air in the hatcher, resulting in the destruction of the environment in the hatcher, which may prolong the incubation time period, or lead to the termination of incubation. Apply to provide a negative pressure dust reduction fresh air system in the hatching room. Set a scientific negative pressure value for the fertilized eggs to be hatched through the PLC logic editor, and then use the pressure sensor to collect the actual pressure value in the hatching room in real time as an adjustment ventilation Based on the output power of the machine, the closed-loop adjustment is realized, so that the actual pressure value of the hatching room always fluctuates around the theoretically set pressure value, so that the entire hatching process is carried out according to the preset conditions, so as to achieve effective hatching and high-efficiency hatching.
