Technical Field
The utility model belongs to the field of valves, and particularly relates to a rotary feeding valve capable of automatically adjusting feeding amount.
Background
The rotary feeding valve is used in conveying system for unloading, metering, quantitative conveying, mixing and packing. The method is widely applied to industries such as chemical industry, environmental protection, petroleum, metallurgy, refractory materials, electric power, cement, plastics, grain and medicine and the like.
In practical application, the feeding amount needs to be adjusted under certain working conditions. The present rotatory feed valve can't adjust the feed volume through the blade number that changes the impeller, and the reason lies in: in order to meet the strength requirement, the impeller and the rotating shaft are generally welded together, so that the impeller needs to be integrally replaced by changing the number of blades, and the cost is very high; moreover, the number of the blades is changed under the condition of not changing the size of the shell, so that the impeller cannot be designed according to the traditional design manual, the design difficulty is high, and the implementation is difficult.
Therefore, the conventional rotary feeding valve generally adjusts the feeding amount by means of a frequency conversion device, that is, the rotating speed of a motor is adjusted by the frequency conversion device, so that the rotating speed of an impeller is changed, and the feeding amount is increased as the rotating speed is higher. This kind of regulative mode is more suitable for the poor material of mobility, and to the good material of mobility, when adjusting the slow rotational speed with the impeller, the material just all discharge's the condition when the silo just communicates with the discharge gate can appear, feed rate increase in the twinkling of an eye when leading to the silo just to communicate with the discharge gate, and then feed rate all can be very little or even zero before next silo communicates with the discharge gate, causes unable even feed.
For example, a rotary feeding valve with patent number CN201920560933.4 granted on 12/10/2019 includes a rotating shaft and blades fixed on the periphery of the rotating shaft, a total material tank is formed between every two adjacent blades, and a partition member detachably mounted in the total material tank includes a base plate and a partition plate whose inner side is fixed on the base plate, and the base plate and the partition plate partition the total material tank into a plurality of material sub-tanks sequentially arranged along the circumferential direction. But this rotatory feed valve is through changing the partition part and adjusting the feed volume, and its stability in order to guarantee to separate the part operation needs the fixed subassembly of multiunit, and it is loaded down with trivial details to change the dismouting, and is troublesome to use, and is inefficient, and is with high costs, needs the partition part of different models of customization simultaneously and additionally needs to occupy storage space, and the dismouting is comparatively troublesome, and is comparatively inconvenient to the maintenance of valve intracavity structure.
