Description

HDPE reinforced pipeline

Technical Field

The utility model belongs to the technical field of the copper wet process, concretely relates to HDPE pipeline lining cage device for heap leaching workshop section solution pump station.

Background

The solution pumping station is the core equipment for blending, supplying and conveying the solution in the storage yard. The delivery and the stacking spraying of all solutions in the heap leaching process are realized by a solution pump station, and the pump station mainly comprises main equipment such as a pipeline liquid inlet pipe, a siphon tank, a secondary spraying pump and the like. The leachate in the solution tank is sucked into a pump cavity through an HDPE pipeline by a siphon tank under the action of a centrifugal pump and is pumped to the next procedure for operation or treatment,

the liquid inlet pipe of the solution pump is an HDPE pipe, which is called High Density Polyethylene in English and is called HDPE for short. Is a non-polar thermoplastic resin with high crystallinity. The HDPE pipe not only has good economical efficiency, but also has a series of advantages of stable and reliable interface, impact resistance, cracking resistance, aging resistance, corrosion resistance and the like. Because of its good economical efficiency, small loss of internal smooth pipeline and strong corrosion resistance, it is generally used for pipeline transportation of normal-temp. corrosive solution in industrial production. When the inlet pipeline of the on-site large-flow high-lift centrifugal pump is used, the phenomena of pipe wall collapse and pipeline path blockage due to bending often occur, so that the feeding of a pump cavity is seriously insufficient, the pump is stopped, and the production is greatly influenced. The cost for directly replacing the pipeline with higher pressure grade is higher (for example, DN600, the price of HDPE pipe of PN10 is nearly twice of that of PN6 pipeline), the self weight of the pipeline is increased, the refitting relates to the complex installation and modification, and the influence on the production is larger. The glass fiber reinforced plastic pipeline modified to be small in strength and flexibility consumes time, the subsequent maintenance cost is high, the maintenance is complicated and time-consuming, the glass fiber reinforced plastic curing time is at least 24 hours, and the production is also greatly influenced.

SUMMERY OF THE UTILITY MODEL

The utility model provides a HDPE pipeline lining cage device, the technical problem who solves is: the problem that a large-diameter HDPE pipeline is easy to shrink and deform under the operation condition of an open-air high-temperature large-flow solution pump is solved.

In order to solve the technical problem, the utility model provides a pipeline is strengthened to HDPE, its characterized in that: comprises an HDPE pipeline and a lining cage attached to the inner wall of the HDPE pipeline; the lining cage mainly comprises a connecting reinforcing rod and lining rings, the outer diameters of the lining rings are consistent with the inner diameter of the HDPE pipeline, and the connecting reinforcing rod does not exceed the outer diameters of the lining rings to weld the two adjacent lining rings into a whole.

Has the advantages that: the utility model discloses utilize corrosion-resistant, the high stainless steel material of intensity to make the lining cage, the lining attaches in HDPE pipeline inner wall to improve the structural rigidity and the stability in use of HDPE pipeline. Simple structure can make the HDPE pipe overcome vacuum suction again.

Detailed Description

In order to make the objects, contents and advantages of the present invention clearer, the following description will be made in further detail with respect to the embodiments of the present invention.

The utility model provides an HDPE reinforced pipeline, which comprises an HDPE pipeline and a lining cage attached to the inner wall of the HDPE pipeline;

the lining cage mainly comprises a connecting reinforcing rod 1 and a lining ring 2, the outer diameter of the lining ring is consistent with the inner diameter of the HDPE pipeline, the connecting reinforcing rod does not exceed the outer diameter of the lining ring to weld two adjacent lining rings into a whole, and the two adjacent lining rings are mutually restrained to form a whole;

the whole lining cage body is made of 316L stainless steel and is used for resisting scouring erosion of acid-containing materials. The diameter of the lining cage is 535mm, which is consistent with the inner diameter of the HDPE pipe. The longest section 1500mm of lining cage device, the shortest section 1000mm, welding has PE material water conservancy diversion stop in the HDPE pipeline, is located the lining cage tip, prevents that the lining cage from shifting under the high-speed impact of fluid, and liquid also can avoid the vortex when flowing at a high speed in the pipeline simultaneously, produces the pipeline vibrations.

The connection reinforcing rod 1 is connected by a stainless steel round pipe with the diameter of 25 multiplied by 3mm, the lining ring 2 is made of a stainless steel plate with the diameter of 8mm, and the inner arc surface and the outer arc surface of the circular tangent plane are designed, so that the fluid impact loss is reduced to the maximum extent. The structure strength is guaranteed, and meanwhile the radius value of the inner circle and the outer circle is reduced as far as possible, so that the drift diameter of the HDPE pipeline runner is guaranteed to the maximum extent, and the inlet feeding amount of a qualified liquid pump is guaranteed.

The HDPE pipeline receives the direct solar radiation position self intensity to reduce, and the power that need overcome the vacuum more highly apart from the liquid level is just bigger, during the installation, need carry out the segmentation cutting to the pipeline section that exceeds the liquid level, then slowly line in the pipeline inner wall with the lining cage, the lining cage adopts transition fit with the pipeline inner wall to adapt to the expend with heat and contract with cold that the HDPE pipeline received day and night the difference in temperature influence and produced.

When the lining cage is installed and tested, the pump cavity and the inlet siphon tank of the qualified liquid pump are filled with water by opening the water replenishing pipe, and the motor frequency needs to be slowly lifted when the pump is started and stopped, so that the phenomenon that liquid drops suddenly in an inlet pipeline to form a water hammer to cause strong damage is prevented.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
