Description

Repairing device for slurry conveying pipeline

Technical Field

The utility model belongs to the technical field of the slurry pipeline transport technique and specifically relates to a slurry pipeline's patching device.

Background

In the slurry pipeline conveying technology, slurry meeting the conditions of concentration and particle size according to the technological requirements is placed in a stirring tank, the slurry stored in the stirring tank is conveyed to a pressurizing main pump by a feeding pump, and the slurry is pressurized by the pressurizing main pump and then conveyed to a next-stage pump station. The main function of the feeding pump is to convey the slurry in the stirring tank to the pressurized main pump and ensure that the inlet pressure of the pressurized main pump meets the requirement.

During the slurry conveying process, solid particles continuously impact, scour and corrode a conveying pipeline, and are particularly seriously abraded at the pipeline welding, diameter changing and turning positions. The wall of the tube becomes thinner through the passage of time until the center point is exposed to sand leakage. In order to solve this problem, the most common method in the prior art is soldering.

However, in the welding repair process, although only one sand hole is formed, the pipe wall in the area becomes thin, the pipe wall is melted to form larger sand holes when a welding rod is contacted with the pipe wall in the welding process, the welding is difficult to be carried out on an original pipe, only large-area surfacing can be carried out, and the reciprocating work of abrasion and leakage can be carried out at the same position after a long time. And due to reciprocating welding, the inner part of the wall of the slurry conveying pipe is uneven, the friction between the slurry and the pipeline is increased in the slurry conveying process, and new sand holes appear after the slurry is welded for 5-7 days.

Therefore, normal production is influenced by repeated work, if the leakage of the high-pressure pipeline is not found in time, more secondary disasters can be brought, and huge economic losses are brought to a using unit. Pipe sections are usually replaced after the repair welding due to wear, which reduces the service life of the pipeline, increases the operation and maintenance cost and affects the production.

Disclosure of Invention

The invention of the utility model aims to: aiming at the existing problems, the repairing device for the slurry conveying pipeline is arranged at the sand hole of the conveying pipeline, so that the service time of the repaired slurry conveying pipeline can be prolonged.

The utility model adopts the technical scheme as follows:

the repairing device for the slurry conveying pipeline is characterized by comprising a box body, wherein the slurry conveying pipeline penetrates through the box body, and the box body is sleeved outside a sand hole of the slurry conveying pipeline.

Due to the adoption of the structure, the box body is sleeved outside the sand hole in the slurry conveying pipeline, and the sand hole is plugged to repair the sand hole in the slurry conveying pipeline. The repair is carried out without welding, so that the problems that the sand holes are damaged again and the inner wall of the conveying pipeline is not flat due to welding can be avoided.

Furthermore, a channel is formed in the box body and is attached to the outer wall of the slurry conveying pipeline, and a filler is arranged between the box body and the channel.

Further, the filler is one of wear-resistant cement and wear-resistant paste.

Furthermore, a pouring port communicated with the box body is formed in the box body.

By adopting the structure, the box body is firstly sleeved outside the slurry conveying pipeline, and the filler is poured into the box body through the pouring port to realize filling.

Further, the filler is at least 0.5cm thick.

Furthermore, two openings are formed in two sides of the box body, the box body is connected with the slurry conveying pipeline in a sealing mode, and no filler is arranged in the box body.

By adopting the structure, the slurry in the slurry conveying pipeline can enter the box body through the sand holes, the box body is filled, and the slurry conveying pipeline is repaired when the box body is filled with the slurry.

Furthermore, the distance between the sand holes and the two ends of the box body is 10 +/-5 cm.

Furthermore, the box body is a cuboid or a cylinder.

Furthermore, the box body comprises two movably connected connecting blocks.

Due to the adoption of the structure, the box body is conveniently arranged outside the slurry conveying pipeline.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

1. the utility model discloses a box body is established to outside cover at slurry conveying pipeline husky eye, through plugging up the husky eye and realizing the repair to slurry conveying pipeline husky eye. Does not need welding for repair, can avoid the problems of sand hole damage again and conveying pipeline inner wall unevenness caused by welding

2. The utility model discloses repair slurry pipeline, improve the life of operation pipeline under pressure, restore once more from original 1 month of restoreing back, restore now for 26 months back, ensured pipeline under pressure's operational safety nature, reduced later stage maintenance cost simultaneously.
