Problems solved by technology

In order to achieve the expected compression ratio, the existing high-pressure double-roll forming machines generally have a screw feeding device, but the disadvantage is that the powdery material needs to discharge a large amount of air during the compression process, and the existing screw feeding device Unable to solve the exhaust problem, causing the material to enter the gap between the rolls with air, causing an air explosion during the gradual compression process, causing severe vibration of the equipment, and in severe cases, it cannot be formed at all

Embodiment Construction

[0025] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but those skilled in the art should understand that such descriptions are merely illustrative and are not intended to limit the scope of the present invention.

[0026] In general, the screw forced feeding device of the present invention is mainly used for the forming and processing of powdery materials, but is not limited to this, for example, it can also be used for feeding fine granular materials. In the present invention, the powdery material is preferably a powdery material without a binder or with a very small amount of binder, or the powdery material itself is a non-sticky or very low-viscosity powdery material. Examples of powdery materials may include, but are not limited to, pulverized coal, powdered cinder, and the like.

[0027] Reference figure 1 , figure 1 Illustratively shows a schematic structural diagram of a screw forced feeding d...

Abstract

The invention relates to a spiral forced-feeding device for shaping powder materials, which comprises a hopper (1), a driving device (2), a spiral shaft (3) coupled with the driving device, a spiral blade (3-2) attached onto the spiral shaft (3) and a spiral cylinder (4) (optional), wherein the spiral shaft (3) is a hollow shaft, and the shaft body (3-1) of the spiral shaft (3) is provided with a plurality of exhaust holes (3-5) which are communicated with a hollow channel (3-4) of the hollow shaft. Optionally, the wall of the spiral cylinder (4) is provided with a plurality of exhaust through holes. The invention also relates to a shaping system with the spiral forced-feeding device and a method for degassing the powder materials in the shaping process by using the spiral forced-feeding device or the shaping system. The invention can exhaust the air from the materials in the forced-feeding process and eliminate or reduce gas explosion phenomenon in the shaping process, thereby stabilizing the quality of shaped products and improving the shaping rate.

Description

Technical field [0001] The present invention relates to a feeding device, and more specifically to a forced feeding device used for forming and processing powdered materials. The present invention also relates to a molding processing system including such a forced feeding device, and a method for degassing the molding processing of powdery materials by using such a forced feeding device or molding processing system. Background technique [0002] At present, the forming and processing of powdery materials in our country generally adopts high-pressure counter-roll forming machines, that is, the powdery materials are added to the gap between two pairs of rollers arranged in parallel, and the processing is arranged on the circumference of one or two rollers according to a certain rule. The two rollers rotate towards each other under the drive of the motor, and the powdery material added between the roll gaps is gradually compressed and formed with the rotation of the rollers, turning...
