Description

Central transmission thickener

Technical Field

The utility model relates to a thickener equipment technical field specifically is a central transmission thickener.

Background

In the actual production process, a thicker ore pulp froth layer is formed on the surface of the thickening tank under the action of the medicament in the ore pulp, the thickness of the froth layer can reach 300mm in winter, and the thicker froth layer on the surface of the thickener not only occupies a large number of clarification areas in the thickener, so that the ore pulp is lost, and the ore pulp settling time is prolonged; and because the froth layer is too thick, the liquid level in the thickening tank is promoted to rise, and ore pulp easily invades to the positions such as a thickener bearing, so that the damage of parts is aggravated, the normal operation of the thickener is influenced, and huge economic loss is caused. In the process of overflow discharge, the content of suspended matters can also be increased by the foam mixed with the supernatant, so that the suspended matters exceed the standard.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

In order to solve the above problems in the prior art, the utility model provides a central transmission thickener can strike off the foam of the surface of water at thickener operation in-process.

(II) technical scheme

In order to achieve the above object, the utility model discloses a main technical scheme include:

the utility model provides a central transmission thickener, includes concentrated pond and harrow frame, concentrated pond inner chamber position is provided with the isolation bucket of cylindrical structure with the heart, form foam enrichment groove between concentrated pond inner wall and the isolation bucket, harrow frame upper portion position equidistant slope is provided with a plurality of scraper blades, harrow frame is close to concentrated pond inner wall both ends and all is provided with the foam and collects the box, foam is collected box export one end and is located foam enrichment groove upper portion, concentrated pond lateral wall position is provided with the foam export with foam enrichment groove intercommunication.

Preferably, a clear water pipe communicated with the outside is arranged on one side, close to the rake frame, of the isolation barrel.

Preferably, the included angle between the scraper and the rotation tangent line of the harrow frame is 15-75 degrees.

Preferably, the included angle between the scraper and the rotation tangent line of the harrow frame is 45 degrees.

Preferably, the foam collecting box is flat, and the foam collecting box is fixedly connected with the rake frame through a fixing frame.

Preferably, the scraper is fixedly connected with the harrow frame through a fixing bolt.

The bottom of the foam collecting box is provided with a gap with the isolation barrel.

(III) advantageous effects

The utility model provides a central transmission thickener. The method has the following beneficial effects:

(1) the thickener rotates in the operation process, the rake frame drives the scraper blade with the inclined top to scrape foam continuously in the foam collecting box, the scraped foam is continuously enriched in the foam collecting box, and the foam flows into the foam enriching groove through the foam outlet and flows out through the foam outlet.

(2) The foam collecting box with the flat structure is more convenient for collecting foam.

Drawings

Fig. 1 is a sectional view of the present invention.

In the figure: 1. a concentration tank; 2. a rake rack; 3. an isolation barrel; 4. a foam enrichment tank; 5. a squeegee; 6. a foam collection box; 7. a foam outlet; 8. a clear water pipe.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, the utility model provides a technical solution: the utility model provides a central transmission thickener, includes concentrated pond 1 and harrow frame 2 1 inner chamber position of concentrated pond is concentric and is provided with the isolation bucket 3 of cylindrical structure, form foam enrichment groove 4 between concentrated pond 1 inner wall and the isolation bucket 3, 2 upper portion positions of harrow frame equidistant slopes to be provided with a plurality of scraper blades 5, harrow frame 2 is close to 1 inner wall both ends of concentrated pond and all is provided with

foam collection box

6, 6 export one end in foam enrichment groove 4 upper portion of foam collection box, 1 lateral wall position in concentrated pond is provided with the foam export 7 with foam enrichment groove 4 intercommunication. And a clear water pipe 8 communicated with the outside is arranged on one side of the isolation barrel 3 close to the harrow frame 2. The included angle between the scraper 5 and the rotation tangent line of the harrow frame 2 is 15-75 degrees. The included angle between the scraper 5 and the rotation tangent line of the harrow frame 2 is 45 degrees. The foam collecting box 6 is flat, and the foam collecting box 6 is fixedly connected with the rake frame 2 through a fixing frame. The scraper 5 is fixedly connected with the harrow frame 2 through a fixing bolt. The bottom of the foam collecting box 6 has a gap with the isolation barrel 3. Thickener is at the operation process, and harrow frame 2 rotates, and harrow frame 2 drives scraper blade 5 that the top slope set up and is continuous to scraping off the foam to 6 directions of foam collection box, and the foam that strikes off is constantly in box 6 is collected to the foam of flat shape, then flows into in foam enrichment groove 4 through the foam export, flows out through the foam export, and the convenience is scraped off the collection to the water piece foam.

The working principle is as follows: thickener is at the operation process, and harrow frame 2 rotates, and harrow frame 2 drives scraper blade 5 that the top slope set up and is continuous to scraping off the foam to 6 directions of foam collection box, and the foam of scraping off is constantly in the foam collection box 6 enrichment of flat shape, then flows into in foam enrichment groove 4 through the foam export, through the foam export outflow.
