Description

Lateral discharging structure of dewatering machine

Technical Field

The invention belongs to the field of garbage treatment equipment, and particularly relates to a lateral discharging structure of a dehydrator.

Background

The dehydrator in the prior art comprises a cylinder body and a shaft body in the cylinder body, wherein a helical blade is fixedly connected to the shaft body, the outer edge of the helical blade is tightly attached to the inner wall of the cylinder body, and the helical blade is spirally wound on the shaft body along the axial direction of the shaft body; the shaft body rotates, the helical blade fixedly connected to the shaft body rotates along with the shaft body, the helical blade on the shaft body conveys materials while dewatering, the pitch of the helical blade in the axial direction of the shaft body gradually decreases, and the helical blade extrudes water in the conveyed materials to flow out of the barrel body to the outside by continuously decreasing the volume in the helical blade. Of course, the dehydration in the prior art can also be realized by other modes, such as keeping the pitch of the helical blade unchanged, and enabling the diameter of the cylinder to be gradually reduced so as to enable the volume in the helical blade to be continuously reduced to realize the dehydration function, or keeping the pitch of the helical blade unchanged, enabling the diameter of the cylinder to be unchanged, and only enabling the diameter of the shaft body to be gradually increased so as to enable the volume in the helical blade to be continuously reduced to realize the dehydration function.

What the ejection of compact mode of hydroextractor adopted among the prior art makes the mode that the material was carried out by helical blade is automatic at the barrel end, but the discharge gate department of hydroextractor still has the axis body to stick at the discharge gate department, and because of the axis body needs the material output resistance of the discharge gate among the fixed so prior art is heavy, often leads to the discharge gate to block up by the frame on the axis body by the material that the helical blade carried out in discharge gate department, the discharge gate blocks up to make the rotation resistance increase on the axis body lead to the hydroextractor stop work even burn out motor etc. after the certain degree. Simultaneously because the outer axis body tip of discharge gate still need install the bearing, the discharge gate is often blocked up and also leads to bearing pressure to increase, and the possibility that the bearing damaged increases.

The ejection of compact of hydroextractor discharge gate department among the prior art relies on material gravity action to fall down naturally, often still need carry out subsequent operation after the material dehydration, so still need set up other equipment in the below of hydroextractor discharge gate department, if other equipment volumes are great, just need raise the hydroextractor to higher height or lengthen the length of hydroextractor, hydroextractor itself is bulky, this kind of design greatly increased the operation degree of difficulty, also make whole equipment volume comparatively bloated.

According to the invention, the lateral screw is used for returning materials, the reverse screw at the end part ensures smooth discharging, the reverse screw at the end part pushes the materials in the opposite direction, so that the pressure of the bearing close to the discharging opening on the shaft body is reduced or no pressure is accumulated, the normal operation of the dehydrator is better ensured, and the lateral screw pushes the materials in the direction away from the cylinder body after the reverse screw pushes the materials, and the materials reach the outer side of the cylinder body through the horn mouth shape; the lateral spiral plays a role in material returning.

Further, the end part of the discharge hole is also provided with a flange used for being connected with other external equipment. In the invention, the flange is convenient for the discharge hole to be connected with other external equipment for installing the material receiving hole.

Compared with the prior art, the invention has the beneficial effects that:

the discharge port is positioned on the side surface of the cylinder body, and the bell mouth design is adopted, so that the discharge pressure is conveniently released, the material is not easily blocked, and the problem of material blocking is thoroughly solved. According to the invention, a side discharging structure is adopted, and the side spiral and the reverse spiral are arranged at the discharging port, so that the material is automatically far away from the cylinder and flows out of the discharging port of the cylinder under the condition of no other external force. In addition, the invention adopts a side discharging structure, thereby better solving the problem that the subsequent process equipment needs to be placed under the discharging port of the dehydrator to need a larger space, and the side discharging port ensures that the placing mode of the subsequent process equipment is more flexible and is not limited by space.
