Abstract
The utility model belongs to the pressure pipeline transporting technology and provides a pressure stabilizing tank of a pressure stabilizing device in a slurry transporting high pressure pipeline, which is formed by the connection of two metal pipes with different pipe diameters, and the two metal pipes are communicated structure, wherein an upper metal pipe (3) is a blind pipe structure and the upper end thereof is provided with a hanging ear (2), the pipe cavity radius of the lower metal pipe (4) is a half of that of the upper metal pipe cavity, the pressure stabilizing tank is connected on the transporting pressure pipeline (1) through the opening of the lower end by welding, and the central axes of the pressure stabilizing tank is vertical to the axes of the transporting pressure pipeline. The slurry transporting high pressure pipeline can stabilize the pressure of the transporting pipeline, and the harm of the equipment due to the pressure fluctuations is reduced.
Description
Technical field
The utility model belongs to the pressure piping conveying technology, mainly proposes the stable-pressure device that a kind of ore pulp is carried the high pressure pipeline.
Background technique
In carrying out the metal ore-dressing practice, utilize floatation need consume the water of several times of crude ore weight, therefore produce a large amount of industrial tailings (mainly being waste water, useless quarrel), and it need be delivered to the mine tailing storehouse.Be used for carrying at a distance its every group three isolation tanks of water-isolated slurry pump system of mine tailing, its power source is the high-pressure multi-stage centrifugal water pump, directly affact the top of ball float in the isolation tank by the high pressure clear water of high pressure clean waterpump generation, and the bottom of ball float is to feed the ore pulp (industrial tailings) of advancing by high-order deckered stock chest or feeding pump, and ball float only makes slurry, water separately as isolation mounting.For make ore pulp can be continuously, evenly, carry stably, every group of isolation tank is furnished with three for slurry safety check and three plasma discharge safety check for, plasma discharge end; Confession, backwater end are furnished with three water inlet purge valves and three backwater purge valves; The switching of feeding slurry and plasma discharge process is by microcomputer control, and six pulp check valves of six surge purge valve and automatic on-offs that driven by hydraulic station are united and finished, and three isolation tank ball floats become 120 degree alternations, realize incessantly feeding simultaneously starching and plasma discharge.
Because the unstability of industrial tailings amount, operation to conveying equipment has produced destabilizing factor, be difficult to avoid occurring the air inlet of finding time, perhaps contain a large amount of foams in the ore pulp in feeding the slurry process, enter in the isolation tank with ore pulp, after these gases enter isolation tank, because of isolation tank seals, in the handoff procedure of feeding slurry and plasma discharge, the high pressure clear water that the high pressure clean waterpump produces compressed gas in the moment that enters isolation tank, in making jar and the pressure in the conveyance conduit change, thereby because of the instability of pressure makes equipment and pipeline along with judder takes place in the fluctuation of pressure, give the basis of equipment and pipeline firm and bring infringement working life.
Summary of the invention
The purpose of this utility model promptly is to propose the stable-pressure device that a kind of ore pulp is carried the high pressure pipeline, and it can be stablized the pressure of conveyance conduit, reduces the harm that equipment is brought because of pressure surge.
The utility model takes following technical proposals to finish its invention task: a kind of ore pulp is carried the stable-pressure device of high pressure pipeline, the surge tank of described stable-pressure device is formed by two different metal tubes connections of caliber and two metal tubes are the structure that communicates, its upper metal pipe is that blind pipe structure and its upper end are equipped with hanger, the tube chamber radius of lower metal pipe is 1/2 of a upper metal pipe tube chamber, it is connected on the discharge pressure pipeline by the lower ending opening welding, and makes the axis normal of surge tank central axis and discharge pressure pipeline.Because tank body upper end be a sealing configuration, being installed on the pipeline air in its jar of back can not discharge because gas can compress, when the mine tailing slurry passes through surge tank under the high pressure of equipment with the air compression in the surge tank.In the handoff procedure for slurry and plasma discharge, gas causes pressure to produce fluctuation, along with the pressure in the fluctuation surge tank of pressure can compress and discharge; When the air in the isolation tank in high pressure clear water effect lower compression and other position pressure when descending, the pressure in the surge tank discharges and makes each site pressure relatively stable, thereby alleviates the vibration that water-isolated slurry pump and conveyance conduit cause because of pressure surge.
The ore pulp that the utility model proposes is carried the stable-pressure device of high pressure pipeline, can stablize the pressure of conveyance conduit, with the harm that reduces because of pressure surge equipment to be brought.
Description of drawings
Schematic representation when Fig. 1 is assemblied in pressure piping for the utility model.
Among the figure, 1, the discharge pressure pipeline, 2, hanger, 3, the upper metal pipe, 4, the lower metal pipe.
Embodiment
The embodiment who provides in conjunction with the accompanying drawings is illustrated the utility model:
As shown in Figure 1, the ore pulp that the utility model proposes carries the surge tank of the stable-pressure device of high pressure pipeline to be formed by two different metal tubes connections of caliber and two metal tubes are the structure that communicates, its upper metal pipe 3 is that blind pipe structure and its upper end are equipped with hanger 2, the tube chamber radius of lower metal pipe 4 is 1/2 of upper metal pipe 3 tube chambers, it is connected on the discharge pressure pipeline 1 by the lower ending opening welding, and makes the axis normal of surge tank central axis and discharge pressure pipeline.
