Abstract

The invention discloses an automatic control system for feeding through pneumatic conveying. The automatic control system comprises a control system body and a controlled system; the control system body comprises a PLC, the PLC is in electric signal connection with a host computer system, the host computer system comprises an industrial computer, a displayer and a memory, and the displayer and thememory are connected to the industrial computer; the controlled system comprises main material towers, an intermediate tower, an air-material mixing chamber and branch material towers, and the main material towers, the intermediate tower, the air-material mixing chamber and the branch material towers are sequentially arranged in the feeding direction through a conveying pipeline; the controlled system further comprises an air blower, and an air outlet of the air blower is communicated with the air-material mixing chamber; branch pipes, communicated with the branch material towers, of the conveying pipeline are provided with branching valves, and the branching valves are in electric signal connection with the PLC. The invention further discloses a control method. Automatic and accurate feeding is achieved; the feeding time is short, the conveying distance is long, and the breakage rate of granular feed is low; the operation is convenient, and the labor cost is reduced; the biological safety problems caused by feed transfer are effectively avoided.

Description

technical field [0001] The invention relates to the field of feeding systems, in particular to an automatic control system for feeding materials in a pneumatic conveying manner. Background technique [0002] It is widely used in the loading and unloading of plastic granules, cement, grain, flour, ore, coal powder, coal ash, molding sand and other bulk materials in the chemical industry, building materials, grain, mining, metallurgy, mechanical power and other departments in my country. With the spread of African swine fever in China, the animal husbandry industry pays more and more attention to the biosecurity of pig farms. In the past, the feeding supply mode of large-scale pig farms relying on feed transfer vehicles to transport feed can no longer meet the strict biosafety requirements of today, and the traditional large-diameter auger feeding mode can not meet the feeding needs of large-scale pig farms, and the traditional In the process of conveying the feed, the pellet...
