Description

Technical Field

[0001] The utility model relates to the technical field of air locking structures, in particular to cement workshop conveying equipment with an air locking mechanism. Background Art

[0002] The air lock feeder is commonly known as a discharger, also called an ash discharge valve. It is mainly used in dust removal, dust cleaning and packaging machines and professional conveying and batching systems in power plants, cement plants, chemical plants and other industries. It is used for air locking or quantitative feeding when conveying dry powdered materials. It can also be used to discharge ash under the ash hopper of the dust collector and air preheater.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN211619338U, which discloses an air-locking unloading valve, which is connected to the inlet of the furnace. The air-locking unloading valve includes a valve body, an inlet hopper, a flap, a sleeve, a rotating shaft, a connecting rod and a balancing block. The valve body is a hollow cylindrical structure and has an inlet end and an outlet end. One end of the inlet hopper is connected to the inlet end of the valve body and the other end is abutted against the upper surface of the flap. Both ends of the rotating shaft are simultaneously connected and fixed to two opposite side walls of the valve body. The sleeve is sleeved outside the rotating shaft and can rotate around the rotating shaft. The flap is connected to the connecting rod through the sleeve. The end of the connecting rod away from the sleeve extends outward to the outside of the valve body and is connected to the balancing block. The outlet end of the valve body is connected to the inlet of the furnace. The air-locking discharge valve disclosed by the utility model reduces the outflow of hot air flow in the furnace, thereby reducing the probability of the hot air flow in the furnace being exchanged with cold air, so that the temperature of the furnace is always maintained at an effective value, improving the effect of drying materials in the furnace and improving work efficiency.
