Environment-friendly gas supply device for asphalt production

The environment-friendly gas supply device for asphalt production comprises a gas supply box, a gas guide cavity is formed in the bottom of the interior of the gas supply box, mounting grooves are formed in the middle positions of the two sides of the interior of the gas supply box, a gas supply pump is arranged at the top of the gas supply box, and inclined flow guide plates are mounted on the two sides of the bottom of the interior of the gas guide cavity; through the structural cooperation of the two groups of synchronously adjusted air guide plates and the second noise reduction filter screen, the air supply amount of the air supply pump can be adjusted, air supply is more flexible and convenient, and through the relative cooperation of the air supply pump, the first noise reduction filter screen and the vertical face of the second semi-arc-shaped flow guide base, the air supply efficiency is improved. According to the device, gas can be filtered and subjected to noise reduction, the flowability of the ga
