Abstract
The invention relates to a pipeline transporter for ore magma, which comprises an ore magma material trough, a valve, an ore magma pipeline and a ceramic filter trough body, wherein a pipe section of the ore magma pipeline easy to have vacuum is provided with a circulating pipeline, one end of the circulating pipeline is connected with one end of the ore magma pipeline, while the other end is connected with the atmosphere. The transporter can completely solve the problem of pipeline vibration, and reduces the pipeline wear and the maintenance of the pipeline.
Description
Technical field
The present invention relates to pipeline conveying device, especially relate to ore pulp pipeline conveying device.
Background technology
In the ore slurry pipeline transportation, ore pulp temporarily can be stored in the ore pulp hopper, carries out Separation of Solid and Liquid in the ceramic filter but finally will be delivered to.Ceramic filter is a kind of solid-liquid separating equipment of novel high-efficiency and energy-saving, and collection micropore ceramics, machine-building, ultrasonic wave clean, the micro computer controlled one that is formed on, and adopt micropore ceramics to make filter medium, use the capillary effect principle and carry out Separation of Solid and Liquid.
Be connected by ore slurry pipeline between ore pulp hopper and the ceramic filter, the mode of feed-type for flowing automatically by discrepancy in elevation potential energy from high to low, ore slurry pipeline is high-end to be connected by valve with the ore pulp hopper, and the ore slurry pipeline low side is an open type, communicates with atmosphere.
Because said structure and feed-type are batch (-type), valve is in the state of continuous open and close.When valve closing, ore slurry pipeline becomes the situation of high-end sealing, low end opening.The every switch of valve once, ore slurry pipeline will vibrate once.Pipe vibration is because due to the ore pulp generation is quickened to flow in the pipeline.When valve closing, the ore pulp in the high-end air-tight state that becomes of pipeline, pipeline can not all flow out, and does not flow out part gravity and equates with atmospheric pressure; Valve forms vacuum to the ore pulp position; When opening valve once more, the ore pulp of new flow ipe flows at vacuum state, produces to quicken stream.Vibration is greatly also caused for safety, production and plant maintenance usually and be had a strong impact on, and also can have influence on the application life of ore slurry pipeline simultaneously.As shown in Figure 1, vacuum state appears in the ore slurry pipeline of this ore pulp pipeline conveying device easily, can cause the vibration of ore slurry pipeline indirectly, is unfavorable for the use and the life-span of ore slurry pipeline.
Summary of the invention
The objective of the invention is to design a kind of ore pulp pipeline conveying device, this device can solve the situation that nuisance vibration appears in ore slurry pipeline.
In order to solve the technical problem of above-mentioned existence, the present invention has adopted following scheme:
A kind of ore pulp pipeline conveying device, comprise ore pulp hopper, valve, ore slurry pipeline and ceramic filter cell body, occur easily at described ore slurry pipeline being provided with circulation duct on the pipeline section of vacuum, described circulation duct one end is connected with ore slurry pipeline, and the other end communicates with atmosphere.Circulation duct is arranged on the valve rear end.Circulation duct is as far as possible near valve.
The existing ore pulp pipeline conveying device of this ore pulp pipeline conveying device is compared, and has following beneficial effect:
(1) because the present invention occurs at ore slurry pipeline being provided with circulation duct on the pipeline section of vacuum easily, utilize law of connected vessels can solve the pipe vibration problem fully.
(2) because the present invention occurs at ore slurry pipeline being provided with circulation duct on the pipeline section of vacuum easily, avoid the ore slurry pipeline vibration, reduced the maintenance of pipe wear and pipeline simultaneously.
(3) solved security hidden trouble.

The specific embodiment
Below in conjunction with Fig. 2 to Fig. 3, the present invention will be further described:
Ore pulp pipeline conveying device of the present invention is disclosed among Fig. 2, it comprises ore pulp hopper 1, valve 3, ore slurry pipeline 4 and ceramic filter cell body 5, occur easily at ore slurry pipeline 4 being provided with circulation duct 2 on the pipeline section of vacuum, circulation duct 2 one ends are connected with ore slurry pipeline 4, and the other end communicates with atmosphere.Circulation duct 2 is arranged on valve 3 rear ends.Circulation duct 2 is as far as possible near valve.
The pipeline section that vacuum appears in ore slurry pipeline 4 easily originates in valve 3, and extends to described ceramic filter cell body 5 directions along described ore slurry pipeline 4, and the length of pipe section that vacuum appears in described ore slurry pipeline 4 easily is S for S length, and its design formulas is:
S＝L-P/(ρ?gsina)；
Wherein: P---refer to atmospheric pressure;
ρ---slurry density;
G---gravity constant;
Angle between a---ore slurry pipeline and the horizontal plane;
The total length of L---ore slurry pipeline;
This design formulas can calculate the concrete length of the pipeline section that occurs vacuum easily, is starting point from valve promptly, move down along ore slurry pipeline 4 in the interval of the long distance of S, and all be the zone that occurs vacuum easily, circulation duct 2 can be arranged in the above-mentioned zone.
The height of described circulation duct 2 is preferably more than or equals the height of described ore pulp hopper 1.Under the normal condition, according to law of connected vessels, when valve 3 was opened, connecting pipe 2 was consistent with the liquid level of ore pulp hopper 1; If connecting pipe 2 is lower than the height of ore pulp hopper 1, when ore pulp hopper 1 material level surpassed connecting pipe 2 height, ore pulp will overflow from connecting pipe 2, but still can realize that the present invention eliminates the purpose of pipe vibration, but can cause the ore pulp waste of material.
When described ore slurry pipeline 4 transported ore pulp, the diameter of connecting pipe 2 was greater than the diameter of described ore slurry pipeline 4.Its principle is, the diameter of connecting pipe 2 depends on the flowability of pumped (conveying) medium in the pipeline, because what carry in the pipeline is ore pulp, the also corresponding diameter that is greater than ore slurry pipeline 4 of the diameter of connecting pipe 2 stops up to prevent connecting pipe.
