Problems solved by technology

[0003] The existing screw conveyors are all directly installed at the bottom of the powder silo, which causes the silo pressure exerted by the powder on the screw conveyor to be in a large fluctuation state all the time, resulting in a deviation between the delivery volume of the screw conveyor and the delivery volume at the design speed , in the existing technology, there is an attempt to solve the problem by installing an unloader between the silo and the screw conveyor, but in the case of poor powder fluidity, it often leads to a gap between the powder silo and the unloader. bridging of powders, often resulting in interruption of powder delivery
At the same time, there is also the problem of bridging when the screw conveyor is directly installed at the bottom of the powder silo

Abstract

The invention discloses a disc type powder precise quantitative feeding device. An upper barrel is connected with a lower barrel through two flanges; a partition plate is fixed between the two flanges which connect the upper barrel and the lower barrel; a material taking hole is formed in the partition plate; a plurality of material taking blades which are uniformly distributed in the radial direction of a material taking rotating disc and are provided with triangular notches are arranged in the upper barrel; feeding blades which are arranged in the radial direction of a feeding rotating disc and are provided with triangular notches are arranged in the lower barrel; the quantity of the feeding blades is equal to the quantity of the material taking blades; the feeding blades are 1.5-2 times the heights of the material taking blades; the material taking rotating disc is fixed to the upper part of a driving shaft in a key connection manner and the feeding rotating disc is fixed to the middle part of the driving shaft in a key connection manner; a feed port is formed in the upper part of the upper barrel; a discharge port is formed in the lower part of the lower barrel; the bottom of the discharge port is connected with the upper part of a temporary storage bin; and the lower part of the temporary storage bin is connected with a feed port of a quantitative screw conveyer. The disc type powder precise quantitative feeding device has the advantages of simple structure, low cost, high control precision and good operating stability.

Description

Technical field [0001] The invention belongs to the technical field of quantitative feeding, and specifically relates to a disc type powder precise quantitative feeding device. Background technique [0002] The screw conveyor has the advantages of simple structure, small cross-sectional size, good sealing, reliable work, low manufacturing cost, and convenient for intermediate loading and unloading. It is widely used in the continuous conveying field of powder materials. The conveying volume is proportional to its speed. In the automatic feeding process of powdery materials, a screw conveyor is usually used to undertake the task of accurately feeding the equipment. [0003] Existing screw conveyors are directly installed at the bottom of the powder silo, resulting in a large fluctuation in the pressure of the powder on the screw conveyor, resulting in a deviation between the conveying volume of the screw conveyor and the conveying volume at the design speed In the existing technol...
