Description

Carbon dioxide powder warehouse blockage-removing and flow-assisting system

Technical Field

The utility model relates to the technical field of powder warehouse blockage-removing and flow-assisting, in particular to a carbon dioxide powder warehouse blockage-removing and flow-assisting system.

Background

The materials stored in the raw material warehouse, the cement warehouse and the mineral powder warehouse in the industries of cement, concrete and the like are all powder materials. In the process of storing in the powder warehouse, because the moisture exists in the warehouse, the powder is easy to adhere to the warehouse wall to form a warehouse wall material, and the warehouse wall material is thicker and thicker along with the time, especially the cement material, so that the volume of the powder warehouse is reduced, and the use efficiency of the powder warehouse is reduced. Moreover, the wall hanging materials can fall off and be doped in the cement materials by themselves, a light person blocks the blanking device, the normal ash discharging and blanking are impossible, a heavy person arches on the hopper in the warehouse, the materials are overhead and can not be discharged, and the material breaking and production stopping are caused, so that the warehouse wall hanging materials are required to be cleaned.

In the prior art, if the mechanical cleaning method is adopted, the method is influenced by high-density dust generated in the warehouse during warehouse cleaning, equipment can not enter the warehouse to clean the warehouse, so that the warehouse cleaning is incomplete and the time is long; if manual warehouse cleaning is adopted, dust pollution is large, danger is large, materials are easy to collapse under emergency conditions, so that people are buried in the warehouse, and people are choked to death.

The cost of powder inventory is calculated from the tonnage of inventory in the inventory, for example: if the dead stock is formed in ten thousand tons of stock, the stock in the stock is basically 4000 tons to 6000 tons, the dead stock is only 1000 tons, the stock clearing cost is about 50 to 70 ten thousand tons according to the current stock clearing cost, and the stock clearing time is 6 to 12 months, because the powder flowing in the stock is discharged during the stock clearing, and equipment or personnel can enter the stock for clearing. If the WLT-KSL 2206 carbon dioxide powder warehouse blocking-clearing and flow-assisting system and the using method are used, flowable powder materials in the warehouse can be discharged, and only 1000 tons of dead materials are left, so that the warehouse clearing cost of 3/5 can be reduced, and the warehouse clearing time is also reduced.

The existing powder warehouse cleaning cycle time is 3-6 years, and once warehouse cleaning, such as using a WLT-KSL 2206 carbon dioxide powder warehouse blocking-cleaning and flow-assisting system and a using method, can prolong the cycle warehouse cleaning time to 8-15 years, and reduce warehouse cleaning times and cost.
