AI Technical Summary
The existing waste gas collection device of the fixed double-arm sand mixer has the problem that the block lacks anti-accidental contact and locking devices, which may cause waste gas to overflow. At the same time, the connection between the exhaust pipe and the box is not tight and can easily separate, affecting the stability of waste gas transportation.
An exhaust gas emission system comprising a sealing plate, a moving component, a pushing component, and a locking mechanism is designed. The combination of the pushing block, the return spring, and the locking mechanism prevents the sealing plate from malfunctioning and the emission pipe from detaching, ensuring stable delivery of exhaust gas.
It effectively prevents exhaust gas leakage and detachment of the emission pipe, improves the safety and stability of the exhaust gas collection device, and avoids environmental pollution and operational complexity.
