Description

TECHNICAL FIELD

[0001] The utility model relates to dust collector valve plate manufacturing technical field, concretely is a kind of tool for dust collector valve plate manufacturing. BACKGROUND

[0002] The function of dust collector equipment is to separate dust from flue gas;The dust collector used in the production line matched with traditional vertical mill equipment is bag dust collector;The dust collector is composed of bag cage, filter bag, air path system, body, ash bucket, stand, air conveying chute, air cylinder, poppet valve box and other components. The air cylinder is fixed on the poppet valve box by bolts, the valve plate is placed inside the poppet valve box, and the valve plate just covers the circular hole at the bottom of the poppet valve box. The valve plate is provided with a threaded hole in the middle, and the cylinder rod of the air cylinder passes through the threaded hole in the middle of the valve plate. During the extension and retraction of the air cylinder, the valve plate plays a role in opening and closing the circular hole at the bottom of the poppet valve box.

[0003] When operating normally, a large amount of (hot) gas flow containing dust passes through the inside of the bag dust collector. When the gas flow blows towards the filter bag, the dust will remain on the outer surface of the filter bag, and the gas flow will pass through the inside of the filter bag and flow to the next process, i.e. the dust collection function of the dust collector is completed. The dust collector is provided with an air path system. After a certain period of time, the pulse valve on the air path system will blow on the filter bag, causing the dust on the outer surface of the filter bag to fall off the filter bag and be collected in the ash bucket. During this process, when the pulse valve on the air path system is not blowing, the valve plate at the bottom of the poppet valve box is separated from the circular hole at the bottom of the poppet valve box. When the pulse valve blows, the valve plate just covers the circular hole at the bottom of the poppet valve box, preventing dust from being blown out.

[0004] The above-mentioned valve plate is made by tightly welding two thin steel plates. During the manufacturing process of the valve plate, the concentricity and flatness of the two steel plates must be ensured. Due to the need for special tooling, the two steel plates often do not have the same concentricity and flatness during the manufacturing process of the valve plate, resulting in poor appearance quality of the manufactured valve plate. At the same time, when the two steel plates are welded by manual pressing, the flatness of the two steel plates after welding is not consistent, i.e. there is a gap between the two thin steel plates after welding. In view of this problem, a tool for manufacturing dust collector valve plates is designed. UTILITY MODEL CONTENTS
