Mine powder accurate proportioning and mixing device and use method

Abstract

The invention relates to the field of accurate proportioning of mine powder, in particular to an mine powder accurate proportioning and mixing device and a use method. The mine powder accurate proportioning and mixing device comprises a proportioning mechanism, a gate mechanism, a material distributing barrel, a micro-proportioning gate mechanism, a scraping mechanism, a mixing barrel and three weighing barrels. According to the mine powder accurate proportioning and mixing device and the use method, The effect of adjusting the outflow volume of raw materials of different proportions is achieved through the material distribution gate plate, the effect of dividing one cylinder is further achieved, one gate mechanism can conveniently control outflow of the three raw materials to be closed atthe same time, the device can be suitable for various raw materials, and it is guaranteed that the raw materials of various proportions can flow out according to the needed raw material proportion atthe same time; a large amount of discharging time of the equipment is saved, a large amount of raw materials remaining in the three conical barrels are cleaned in time through the effect of the scraping mechanism, the proportioning precision of the raw materials is improved, the three conical barrels are synchronously cleaned, and the situation that the next proportioning speed is affected due tothe fact that the conical barrels are not synchronously cleaned up is avoided.

Description

technical field [0001] The invention relates to the technical field of mixing devices, in particular to a mixing device with precise proportioning of powder for mines and a method for using it. Background technique [0002] Cementitious material is the key product of cemented backfill. A well-performed cementitious material can ensure the strength of the backfill body required for production at low ash content, which directly determines the production cost of backfill mining. On the basis of the laboratory test and research of the cementitious material, the industrial preparation is carried out according to the optimal ratio, and finally the finished material which can be used for mine filling is obtained. The accuracy and uniformity of the solid powder mixing ratio is the key to the quality of the cementitious material. The traditional solid powder mixing device is often controlled by a relay contactor, and there are many electrical appliances used and connected, so there a...

Problems solved by technology

[0004] Although this plan specifically pointed out a formula for solid powder, it is impossible to accurately proportion the raw materials of solid powder, and when traditional raw material proportioning, it is often necessary to use multiple gates to control the feeding of multiple cylinders, which cannot be based on The outflow speed of raw materials and the size of the discharge port are adjusted within a certain period of time to obtain the proportion of raw materials required for outflow, which often wastes a lot of time for the equipment to discharge, and after the weighing hopper is weighed and the material is discharged, the metering hopper often There will be a large amount of raw materials that cannot be cleaned in time, which will affect the precise proportioning of raw materials, and conventional cleaning equipment can only clean one weighing hopper, and cannot clean multiple weighing hoppers, which will affect the speed of the next batching
