As a preferable aspect of the present invention, the protection cover is arc-shaped, and the protection cover is bent toward the pipe body.

Through adopting the arc-surface-shaped protection casing, the impurity in the sand-containing flowing back can be avoided piling up on the protection casing.

As the preferred scheme of the utility model, the protection casing with the body passes through the clamp connection.

The protection casing and body clamp connection are convenient for change the protection casing.

As the preferred scheme of the utility model, the protection casing bottom sets up the connecting rod, the connecting rod with clamp connection.

As the preferred scheme of the utility model, the body inboard and/or outside surface is provided with the anticorrosive coating.

The anti-corrosion layer is arranged on the inner side surface and the outer side surface of the pipe body, so that the anti-corrosion capability of the pipe body can be improved, and the service life of the pipe body is prolonged.

As the preferred scheme of the utility model, the anticorrosive coating is the anticorrosive coating of pottery.

As the preferred scheme of the utility model, it is adjacent the body passes through flange joint.

As the utility model discloses a preferred scheme, the body level sets up, the body is provided with first through-hole and second through-hole, and is a plurality of the setting is arranged to first through-hole the bottom surface of body, and is a plurality of the setting is arranged to the second through-hole between the well cross-section of body and the bottom surface. The sand washing direction of the second through hole can obliquely push sand and stone towards the direction far away from the sand washing pipe, so that the sand washing effect is better.

As the preferred scheme of the utility model, body sub-unit connection has the stay tube.

Through setting up the stay tube, can support the body, make body and separator ground have certain distance, avoid the interior bottom grit of separator to cause the erosion to the body at the disturbance in-process.

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

1. according to the technical scheme, on the basis of keeping the basic functions of the original sand washing pipeline, the protective cover is arranged, and the anti-corrosion layer is arranged on the inner surface and the outer surface of the pipe body, so that the service life of the sand washing pipeline is further prolonged, the pipeline replacement period is prolonged, and the cost is reduced.

2. By adopting the sand washing pipeline structure in the technical scheme, all components can be prefabricated in advance, and are installed under the condition of production stop, so that the safety risk of construction does not exist.

3. The adjacent pipe bodies and the protective covers are detachably connected, the process is simpler when the protective covers or the sand washing pipes are replaced, and less materials and working hours can be spent.

4. After changing body or protection casing, can not influence the function of whole sand washing pipeline, if what change after the maintenance is the protection casing, can spend still less sand washing pipeline maintenance cost.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1

A sand washing pipeline for a horizontal separator is shown in figure 1 and comprises a plurality of pipe bodies 1 which are in butt joint, and a protective cover 2 is arranged above the pipe bodies 1 to shield sand-containing liquid drainage falling from the upper part of the sand washing pipeline, as shown in figures 3 and 4.

Preferably, the top surface of protection casing 2 is provided with the water conservancy diversion face, with the both sides of sand-containing flowing back guide pipe body 1 axis to the grit in the sand-containing flowing back is piled up in protection casing 2 is avoided. Specifically, the shield 2 may have an arc-shaped cross section as shown in fig. 4, or may have an inverted "V" shaped cross section.
