Detailed Description
As shown in fig. 1 and 2, the pig feed raw material silo with cooling and dehumidifying functions comprises a silo 15, an air inlet device, a cyclone dust collector 1 and a plurality of ventilation devices arranged in the silo 15, wherein the ventilation devices comprise a ring pipe 12 sleeved outside the silo 15, a gas collecting box 10 arranged in the silo 15, the ring pipe 12 is communicated with the gas collecting box 10 through a plurality of mesh pipes 11, the ventilation devices with the structures can uniformly feed air into raw materials, the mesh pipes 11 are uniformly distributed around the axis of the silo 15, the air inlet device comprises an air inlet box 4, one end of the air inlet box 4 is communicated with a fan 3, the other end of the air inlet box 4 is communicated with a plurality of air inlet pipes 8, the air inlet of the cyclone dust collector 1 is communicated with the ring pipe 12 in each air inlet device through a plurality of exhaust pipes 2, and each air inlet pipe 8 and each exhaust pipe 2 are alternately communicated with each air inlet pipe 12.
For convenience of description of the operation, each of the ventilation devices communicating with the gas collection box 10 is set as a first ventilation device, each of the ventilation devices communicating with the cyclone 1 is set as a second ventilation device, and the first ventilation device and the second ventilation device are alternately arranged.
The application process of the invention is as follows: for example, when the temperature of the raw material in the middle of the silo 15 exceeds 40 ℃, a valve on an air inlet pipe 8 of each first ventilation device in the middle is opened, then a fan 3 is started, air enters each first ventilation device in the middle of the silo 15, and after the air passes through the raw material, the air is discharged into the cyclone dust collector 1 from the second ventilation device, so that the raw material is locally cooled.
A heat exchange coil 6 is arranged in the air inlet box 4, the heat exchange coil 6 is communicated with a steam source, and the steam source is a boiler. The raw materials purchased in the rainy days are moist, and after being put into the silo 15, the raw materials can be subjected to moisture removal firstly in the silo 15 at the moment and then subjected to air supply and temperature reduction in the subsequent storage process so as to prevent mildew.
