Description

Technical Field

[0001] The utility model relates to the technical field of machinery and valves, in particular to an integrated double-rotor star-shaped ash discharge valve device. Background Art

[0002] The star-shaped ash discharge valve is also called a star-shaped discharger and an electric air lock valve. It is a device for unloading the collected dust materials in the dust removal system. The star-shaped ash discharge valve is widely used in the feeding and ash discharge systems of chemical, metallurgical, mining, cement, dust removal, environment, grain and other industries. It is also one of the indispensable equipment for drying materials, dust particles, etc. The working principle of the star-shaped ash discharge valve is to rely on the gravity of the material and the rotation of the ash discharge valve to continuously and evenly discharge the material in the bin or continuously and evenly feed it to the next process device. The star-shaped ash discharge valve is divided into a circular star-shaped ash discharge valve and a square star-shaped ash discharge valve according to its appearance and structure. The advantages are stable operation, uniform discharge, reasonable structure, compact size, good sealing performance, convenient maintenance, and long service life.

[0003] Since the unloaded materials contain dust or have a high water content, the star-shaped ash unloading valve in the prior art is prone to hardening during the unloading and stacking process, resulting in the star-shaped ash unloading valve being stuck or idling. The sticking causes the motor to stop for protection, and the idling causes the production line to fail to meet the production standards, wasting energy. After the above situation occurs, the star-shaped ash unloading valve needs to be inspected and repaired to clean the blocked materials in the blades. During this period, the maintenance time is very uncertain. If it causes equipment damage, the production will be stopped for a longer time. Especially on the assembly line, the shutdown of the feeding position will cause the entire production line to stop, which will bring immeasurable losses to production. Summary of the invention

[0004] The purpose of the utility model is to provide an integrated double-rotor star-shaped ash discharge valve device. The technical problem to be solved by the utility model is: to replace the existing single-rotor method with an integrated double-rotor method, and the double-rotor star-shaped ash discharge valve adopts one set in use and one set as spare during use; when a jam or the like occurs, the spare mechanism is quickly started to operate, and then the mechanism with the problem is inspected and repaired, so that the production line will not be stopped due to long-term downtime.
