Abstract
The invention discloses a shot blasting ingress pipe capable of ventilating and reducing temperature, which is provided with a ventilating channel formed between an inner pipe and an outer pipe, wherein one end of the ventilating channel is connected with a shot blasting machine, and the other end of the ventilating channel is communicated with the atmosphere. The negative pressure generated by the rotary blades of the shot blasting machine is used for enabling cold air to continuously enter the ventilating channel and take away the heat of the inner pipe, thereby reducing the temperature of the wall of the inner pipe and keeping the temperature of the pipe wall not be 50 DEG C higher than room temperature. The cold air sucked by negative high pressure not only enters the ventilating channel of the ingress pipe to take away the heat of the inner pipe but also enters the shot blasting machine through the ingress pipe so as to simultaneously cool the inner-wall lining plate of the shot blasting machine and a shot blasting impeller to reduce the temperature of the inner-wall lining plate and the shot blasting impeller, thereby improving the service life of the ingress pipe, the impeller, the inner-wall lining plate, the blades and other easily-worn parts.
