Abstract

The utility model discloses a deep cone thickener which comprises a steel pool, a bridge frame, a driving device, a flocculation bucket and a main shaft, wherein a plurality groups of grids are fixedly welded on the inner wall of the steel pool respectively in an encircling manner; a scraping collecting device is mounted at the lower end of the main shaft, and comprises an upper bracket and a lower bracket both fixedly mounted at the lower end of the main shaft; a left inclined spiral scraping plate and a right inclined spiral scraping plate are fixedly connected between the upper bracket and the lower bracket. According to the utility model, the structure is reasonable; through the arrangement of the plurality groups of grids and the scraping collecting device, the shearing force is strengthened, a certain amount of interstitial water and free water wrapped by flocs are removed to further increase the concentration, so that the operating efficiency and quality of the thickener are improved.

Description

Deep cone thickener

Technical field

The utility model relates to the thickener field, specifically a kind of deep cone thickener.

Background technology

Thickener is mainly used in the industry-by-industry tail muddy water such as coal, metallurgy, chemical industry, environmental protection and processes on this link, thickener be mainly utilize sedimentation theory that the solid particle in ore pulp is deposited to the pond of thickener at the bottom of, clarified solution is gone out from the downflow weir overflow, to realize Separation of Solid and Liquid.

The disposal ability of thickener and settling area have than Important Relations, on the basis of traditional concentrator, release a kind of lamella thickener, this lamella thickener be domestic application comparatively widely, lamella thickener is to increase settling area by swash plate to increase thickener unit are treating capacity, reaches the purpose that increases treating capacity.

Because pan feeding concentration is higher, the large concentrated phase layer of floc sedimentation is difficult to deviate from the speciality such as free water, the requirement of thickener is had to larger shearing force, be convenient to the rising of free water to cut off as early as possible large floc sedimentation, and existing thickener exists obvious deficiency in this respect.

The utility model content

The purpose of this utility model is to provide a kind of deep cone thickener, by many groups grid and scrape storage, increases shearing force, and removes the free water of a certain amount of Interstitial Water and floc sedimentation parcel, and concentration is further improved.

The technical solution of the utility model is as follows:

A kind of deep cone thickener, include steel pond, crane span structure, drive unit, flocculation bucket and main shaft, it is characterized in that: the inwall around the steel pond is fixedly welded with respectively many group grids, the lower end of described main shaft is equipped with scrapes storage, the described storage of scraping includes the upper and lower support that is fixedly mounted on the main shaft lower end, is fixedly connected with the left and right spiral scraper plate of inclination between described upper and lower support.

Described deep cone thickener is characterized in that: described many group grids are uniformly distributed on the inwall in steel pond.

The beneficial effects of the utility model:

The utility model is rational in infrastructure, by many groups grid and scrape storage, has increased shearing force, and has removed the free water of a certain amount of Interstitial Water and floc sedimentation parcel, concentration is further improved, thereby improved operating efficiency and the work quality of thickener.

The accompanying drawing explanation

Fig. 1 is the utility model structural representation.

The specific embodiment

Referring to Fig. 1, a kind of deep cone thickener, include steel pond 6, crane span structure 1, drive unit 2, flocculation bucket 3 and main shaft 4, inwall around steel pond 6 is fixedly welded with respectively many group grids 5, the lower end of main shaft 4 is equipped with scrapes storage, scrape storage and include the upper and lower support 7 that is fixedly mounted on main shaft 4 lower ends, be fixedly connected with the left and right spiral scraper plate 8 of inclination between upper and lower support 7.

In the utility model, organize grid 5 more and be uniformly distributed on the inwall in steel pond.

Claims

1. a deep cone thickener, include steel pond, crane span structure, drive unit, flocculation bucket and main shaft, it is characterized in that: the inwall around the steel pond is fixedly welded with respectively many group grids, the lower end of described main shaft is equipped with scrapes storage, the described storage of scraping includes the upper and lower support that is fixedly mounted on the main shaft lower end, is fixedly connected with the left and right spiral scraper plate of inclination between described upper and lower support.

2. deep cone thickener according to claim 1, is characterized in that: organize grids more described and be uniformly distributed on the inwall in steel pond.
