Description

Technical Field

[0001] The utility model relates to the technical field of ash storage and ash mixing, and particularly relates to a blowing device for ash mixing operation and an ash mixing tank thereof. Background Art

[0002] The existing ash storage tank in the ash conveying station only has the function of ash storage. The traditional ash mixing operation mode needs to mix the ash materials evenly by emptying the tank twice, and finally carry out the ship loading operation. The specific operation is as follows: First, break the bags through the operation console, and put Shandong cement, low-temperature early-strength cement and ash mixing materials into the ash storage tank in proportion successively. Then, start the tank emptying operation twice through the main control room. On average, each tank emptying operation takes 40 minutes, that is, it takes 80 minutes to complete the mixing of ash materials in a single tank. If there is no spare ash storage tank during the ash mixing operation, the tank emptying cannot be carried out, resulting in the situation of tank pressing. It is necessary to empty the ash storage tank after inputting the ash materials in the other ash storage tanks into the ship before carrying out the tank emptying and ash mixing operation. Waste materials will be generated during the operation. On average, 0.4 tons of waste materials will be generated each time the tank is emptied, that is, 0.8 tons of waste materials will be generated for completing the mixing of a single tank. The generated waste materials need to occupy a large amount of human and material resources costs. Content of the Utility Model
