Round feeding valve for Daqu production line

Abstract

The invention discloses a circular discharge valve used for a koji production line, comprising a cylindrical valve body and a plurality of blades hinged to the valve body and capable of being simultaneously opened for discharge, wherein the valve body is connected with a blade driving device, and the initial opening point of each blade is located on the axial central plane of the valve body, so that materials are stacked in pyramid shape after falling off. The stretching movement of a piston rod of the cylinder of the blade driving device drives a driving ring to circumferentially reciprocate along a guide wheel. When the piston rod of the cylinder stretches out, the driving ring drives the blades to rotate to the outside of the valve body so as to be opened, and since the initial opening points of the blades are located on the axial central plane of the valve body, the materials are stacked in pyramid shape after falling off. When the piston rod of the cylinder retracts, the blades are driven to rotate reversely to seal the inner chamber of the valve body. When discharge is not needed, the blades of the discharge valve seal the inner chamber of the valve body; when discharge is needed, piston rods of all cylinders are controlled to open the blades simultaneously; and after discharge is finished, the piston rods are controlled to retract to return all the blades.

Description

technical field [0001] The invention relates to a blanking valve, in particular to a circular blanking valve for a Daqu production line. Background technique [0002] According to the current process of manually stepping on koji, when the koji material is piled into the koji mold box with a shovel, the koji material will be piled up in a pyramid state, and the shape of the pyramid can be a turtle-back shape with a high middle and low sides. , and the density uniformity of Daqu also affects the fermentation result of koji. Therefore, before Daqu pressing, the accumulation state of the materials should be piled up into a pyramid shape as much as possible, and only when the materials fall from the center point above, can the materials be in a natural accumulation state. The scheme generally adopts a push-pull blanking valve with one-sided opening or two-sided opening. The results of these two schemes are not ideal, and there will always be uneven phenomena. Moreover, in order...

Problems solved by technology

Therefore, before Daqu pressing, the accumulation state of the materials should be piled up into a pyramid shape as much as possible, and only when the materials fall from the center point above, can the materials be in a natural accumulation state. The solution generally adopts a push-pull feeding valve with one-sided opening or double-sided opening. The results of these two solutions are not ideal, and there will always be uneven phenomena.

Moreover, in order to ensure production efficiency, when multi-point feeding is required, multiple storage hoppers will be arranged side by side or arranged in a Narita shape. The above-mentioned push-pull structure feeding valve needs to occupy a large space, and the production site is often not available. There is such a large space to meet the requirements; in addition, the push-pull blades still need sliding tracks, otherwise there will be cases where the blades are not tightly fitted, and the structure is complicated
