Description

Technical Field

[0001] The utility model relates to the technical field of discharge valves, in particular to a double-layer composite discharge sealing valve. Background Art

[0002] At present, traditional rotary feeders or heavy hammer flap valves are commonly used for dust collectors, cyclones and other unloading in cement, steel and other industries in my country. The use of rotary feeders has a high failure rate and high energy consumption. Each rotary feeder consumes a large amount of electricity resources every month. Failure of equipment during operation not only increases the labor burden of enterprise employees, but also causes equipment damage and production line shutdown in serious cases, seriously affecting the normal safe production of enterprises. The use of heavy hammer rotary feeders has disadvantages such as poor sealing. Air leakage during equipment operation reduces the effective work of the fan and reduces the operating capacity of the equipment. Long-term air leakage poses a certain risk to the safe operation of the equipment. Based on environmental protection, energy saving, and convenient maintenance, our company focuses on the design and development of feeders for dust collectors, cyclones and other equipment, and develops and launches double-layer composite unloading sealing valves, which solves the common problems of high energy consumption and poor sealing. Its advanced technical performance, quality reliability, operational stability, and environmental protection functionality are fully recognized by cement plant users. Utility Model Content

Through the cooperation of high-temperature resistant soft curtain and counterweight slats, when the material weight reaches a certain mass, the soft curtain automatically lifts the material to flow out of the conveying equipment. The energy consumption of the equipment itself is zero, and no additional power equipment is required. The sealing effect is good and the failure rate is low, which improves the practicality of the device.

The high-temperature resistant soft curtain is installed on the top of the cylinder, and a plurality of groups of counterweight slats are evenly installed on the high-temperature resistant soft curtain by bolts. The counterweight slats are used to make the high-temperature resistant soft curtain droop naturally, and the soft curtain can contact with the rear tilt plate after drooping. When the weight of the material reaches a certain mass, the high-temperature resistant soft curtain is automatically lifted to make the material flow out of the conveying equipment, which can reduce the overflow of material smoke and dust, enable the equipment to have wind locking ability, and improve the practicability of the device.
