Abstract

The utility model discloses a full-tailing material stirring structure which comprises a stirring shaft and an impeller connected with the stirring shaft in a radial direction through a flat key, wherein the impeller is arranged on the stirring shaft; a ring groove is arranged above or below the connection part of the stirring shaft and the impeller in a ring way, and the annular groove is provided with a limiting ring, and the limiting ring is axially connected with the impeller through a screw.

Description

Full tailing material stirring structure

Technical Field

The utility model belongs to the technical field of mine filling equipment, and particularly relates to a full tailing material stirring structure.

Background

In the field of mine filling, a vertical stirring barrel with a double-layer impeller structure is generally adopted for stirring the whole tailing materials containing a relatively large proportion of fine particles. The existing stirring impeller is fixed in the following manner that the rotation direction is fixed by adopting a flat key, and the axial direction of a stirring shaft is fixed by adopting a fine tooth round nut. The fixing mode brings the following technical problems: 1. because the inner holes of the impellers are not consistent, the upper and lower impellers cannot be consistent when the upper and lower impellers are arranged on the stirring shaft, and the parts of the equipment are not simplified. 2. The impeller is soaked in the stirring medium for a long time, and the thread structure is easy to rust and wear and difficult to detach. 3. The round nut is disassembled and assembled by special tools, so that the disassembly and maintenance are inconvenient. 4. The stirring shaft is required to be processed with a large thread matched with the round nut, and the processing cost is high. Therefore, improvements and design of stirring structures are a major issue.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provides a full tailing material stirring structure.

In order to achieve the above purpose, the technical scheme provided by the utility model is as follows:

the all-tailing material stirring structure comprises a stirring shaft (2) and an impeller (1) which is radially connected with the stirring shaft (2) through a flat key (4); an annular groove (6) is arranged above or below the joint of the stirring shaft (2) and the impeller (1), a limiting ring (3) is arranged on the annular groove (6), and the limiting ring (3) is axially connected with the impeller (1) through a screw (5).

Preferably, the outer edge of the ring groove (6) and the inner edge of the limit ring (3) are conical surfaces which are matched with each other.

Preferably, the contact surface edge of the limiting ring (3) and the impeller (1) is a conical surface matched with each other.

Preferably, a screw hole is formed in the limiting ring surface of the limiting ring (3), a screw hole is formed in the connecting surface of the impeller (1) and the limiting ring (3), and the screw (5) is used for axially connecting the limiting ring (3) with the impeller (1) through the screw hole.

Preferably, the limiting ring (3) is composed of two split semicircular rings.

Preferably, the impeller (1) comprises an upper impeller and a lower impeller arranged on the stirring shaft (2).

The utility model also provides a full-tailing material stirring device, wherein the full-tailing material stirring structure is arranged in the full-tailing material stirring device.

The utility model is further described below:

in the utility model, a ring groove is arranged above or below the joint of the stirring shaft and the impeller, the impeller is fixed by adopting an impeller limiting ring which is divided into two halves in the axial direction, the limiting ring and the impeller are provided with conical surfaces which are matched with each other, the limiting ring and the impeller are connected by adopting bolts, and when the bolts are screwed down, the limiting ring is pressed in the ring groove on the stirring shaft by the acting force generated by wedging the conical surfaces, so that the axial fixation of the impeller is realized. When the impeller is detached, the impeller can be detached by only detaching the connecting bolts, and a special tool is not needed. While radial positioning of the impeller is likewise achieved by means of flat keys.

Compared with the prior art, the utility model has the beneficial effects that:

the upper impeller and the lower impeller can be made into the same size, so that the equipment structure is simplified, and the production and after-sale inventory pressure is reduced.

Original thread processing on the stirring shaft is canceled, so that the processing of the stirring shaft is simpler, and the processing cost is reduced.

Can be assembled and disassembled without special tools, and the disassembly and the assembly are simpler and more convenient.

The screw thread rust and the locking can not be dismantled after long-time use.
