Abstract

The utility model discloses a coal washing product discharging chute, wherein a spigot (6) is processed on a fixed seat (1), the lower end of a circular ultra-high molecular polyethylene pipe (3) is inserted into the spigot (6) of the fixed seat (1), and the upper end of the circular ultra-high molecular polyethylene pipe (3) is connected with a transition pipe (5). A sealing ring (2) is arranged between the outer circumference of the lower end of the ultra-high molecular polyethylene round pipe (3) and the inner side wall of the spigot (6). The upper end of the ultra-high molecular polyethylene round pipe (3) is connected with the transition pipe (5) through a flange (4). The transition pipe (5) is of a square-top-bottom-circle structure. The utility model fully utilizes the characteristics of wear resistance, smoothness and the like of the ultra-high molecular polyethylene circular tube, enhances the wear resistance of the chute, has the leakage compensation for the iron chute within 10 months, and has no problem in one year or half of the prior use. Therefore, the labor intensity of operators is reduced, the service life of the chute is prolonged, and the material and labor cost are saved.

Description

Coal washing product blanking chute

Technical Field

The utility model relates to a coal washing product blanking chute.

Background

The product blanking chute of the previous coal washery is an iron chute and has a square cross section structure. As the water content in the products of the coal washing plant is large and the coal amount of-0.5 mm is large, the iron chute can be corroded and worn through when the stress point is less than one year in the actual production process. Leakage repair and recovery are needed after wearing. The chute can be blocked due to the accumulation of the slack coal after the leakage repairing, the treatment method is to use a sledge hammer to knock the chute, the chute can only be stopped when the chute is seriously accumulated, and the normal production of a coal washery is seriously restricted.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of providing a novel coal washing product blanking chute structure to overcome the defects that an iron square chute in the prior art is easy to wear through, and the chute is blocked due to accumulation of slack coal after leakage repairing, so that the normal production of a coal washing plant is influenced and the like.

The utility model adopts the following technical scheme: the ultra-high molecular polyethylene circular tube chute is used for replacing an iron square chute, a spigot is processed on the fixed seat, the lower end of the ultra-high molecular polyethylene circular tube is inserted into the spigot of the fixed seat, and the upper end of the ultra-high molecular polyethylene circular tube is connected with the transition tube.

And a sealing ring is arranged between the outer circumference of the lower end of the ultra-high molecular polyethylene pipe and the inner side wall of the seam allowance.

The upper end of the ultra-high molecular polyethylene round pipe is connected with the transition pipe through a flange.

The transition pipe is of a square-top-bottom-circle structure.

The ultra-high molecular polyethylene round pipe is an ultra-high molecular polyethylene PE pipe.

By adopting the technical scheme, the characteristics of wear resistance, smoothness and the like of the ultra-high molecular polyethylene circular pipe are fully utilized, the wear resistance of the chute is enhanced, leakage of the iron chute can be mended within 10 months originally, and the problem does not occur in the prior use of the chute for one year or half. Therefore, the labor intensity of operators is reduced, the service life of the chute is prolonged, and the material and labor cost are saved.

Fig. 2 is a schematic view of a fixing base of the present invention.

In the figure, 1-fixed seat, 2-sealing ring, 3-ultra-high molecular polyethylene round tube, 4-flange, 5-transition tube, 6-spigot.

Detailed Description

The embodiment of the utility model comprises the following steps: as shown in fig. 1, a spigot 6 is processed on the fixed seat 1, the lower end of the ultra-high molecular polyethylene circular tube 3 is inserted into the spigot 6 of the fixed seat 1, and the upper end of the ultra-high molecular polyethylene circular tube 3 is connected with a transition tube 5.

And a sealing ring 2 is arranged between the outer circumference of the lower end of the ultra-high molecular polyethylene round pipe 3 and the inner side wall of the spigot 6.

The upper end of the ultra-high molecular polyethylene round pipe 3 is connected with a transition pipe 5 through a flange 4.

The transition pipe 5 is of a square and round structure.

After the ultrahigh molecular polyethylene PE pipe is used for replacing an iron chute at the product discharging chute, the inner wall of the PE pipe is smooth and is not easy to block, and the labor intensity of workers is reduced; the high molecular material is wear-resistant, the service life of the chute is prolonged, and the material cost is saved. The leakage of the iron chute can be repaired within 10 months originally, and the problem does not occur after the iron chute is used for one year or half.
