A kind of slag cleaning device for chemical production boiler
The invention provides a slag removal device for a chemical production boiler, which relates to the technical field of slag removal devices, and solves the problem that the slag falls into the collection box due to the slag falling into the collection box after being scraped into the collection box. Falling will easily lead to the spread of dust, which will affect the health of the operator. A slag cleaning device for a chemical production boiler includes a collecting box, a cleaning part and a dust suction part; the collecting box is placed on the ground. Through the setting of the slot, there is a slot on the collection box, and the head end of the baffle is plugged into the slot, and the slot is an inclined groove structure, so that on the one hand, the cooperation between the baffle and the slot can realize The sealing of the collection box prevents the dust from spreading due to the slag falling in the collection box; on the other hand, the inclined slot prevents the slag from remaining in the slot, which leads to the sealing of the baffle and the slot Not tight.
