Abstract
The utility model relates to an improvement of a high-speed spiral flow generating device, in particular to an adjustable high-speed spiral flow generating device. The adjustable high-speed spiral flow generating device comprises an upper barrel and a lower barrel. The upper barrel and the lower barrel are connected together through threads. Three barrel nozzles are evenly distributed on the same circumference of the lower barrel in the tangential direction, and meanwhile the cross sectional area of a barrel outlet located in the upper barrel is one quarter that of a barrel inlet located in the lower barrel. According to the adjustable high-speed spiral flow generating device, the cross section of the inlet and the cross section of the outlet change a lot, so the ore pulp lifting speed can be increased, and usually the outlet speed can be increased by four times of the inlet speed; meanwhile, the service life of the barrels is prolonged, and the production cost is lowered greatly; meanwhile, the barrels will not be blocked, and smooth progress of deep-sea mining operation is guaranteed.
Description
Technical field
The utility model relates to a kind of improvement of high-speed screw flow generating apparatus, particularly a kind of adjustable high-speed helical flow generating device.
Background technique
High-speed screw flow generating apparatus is mainly used in deep-sea mining ore pulp and promotes, current guide-vane helical flow generating device adds several fixing guide vanes with certain laying angle at pipeline section inwall, in the time that incoming flow passes through this pipeline section, incoming flow not only travels forward vertically, and generation circumferential movement, the resultant motion of the two has just formed spiral flow in pipes, Here it is guide-vane helical flow generating device.This device, due to multi-disc guide vane being installed, has increased the local resistance in pipe, and under promoting at a high speed, energy consumption is larger, and high speed slurry fails to be convened for lack of a quorum and blade collides, and causes collision loss, will accelerate the wearing and tearing of guide vane, and working life is shorter; In addition, sometimes also can plugging, affect normal deep-sea mining operation.
Model utility content
The utility model object is to provide a kind of adjustable high-speed helical flow generating device that overcomes above-mentioned defect.
Technical solutions of the utility model: a kind of adjustable high-speed helical flow generating device, comprise upper cylinder, lower cylinder body, upper cylinder and lower cylinder body are together by a threaded connection, at tangential uniform three cylindrical shell nozzles of the same circumference of lower cylinder body, be positioned at cylindrical shell on upper cylinder outlet cross-section area simultaneously and be 0.25 times of cross-section area that is positioned at the cylindrical shell import on lower cylinder body.
A kind of adjustable high-speed helical flow generating device, between described upper cylinder and lower cylinder body, connecting thread is trapezoidal thread.
The utility model cylindrical shell height is adjustable, can adjust mining slurry spiral intensity, meets the needs of different lifting speeies; Meanwhile, import and export changes of section larger, can improve the speed that promotes ore pulp, 4 times of conventionally outlet velocity can be brought up to entrance velocity; Due to the existence of high-speed screw stream, radially increase gradually in the distribution of riser internal pressure, be that die place pressure is less, tube wall place pressure is larger, has formed certain pressure gradient, cause ore particles to be assembled near movement die under the effect of pressure reduction, make the concentration of tube wall place slurry particles lower, reduced the wearing and tearing that the collision of particle has simultaneously also alleviated tube wall, play the effect of energy-saving and emission-reduction, improve the working life of cylindrical shell simultaneously, cost of production is significantly reduced; Cylindrical shell can not stop up simultaneously, has guaranteed carrying out smoothly of deep-sea mining operation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the worm's eye view of Fig. 1.
In figure: 1 cylindrical shell outlet, 2 upper cylinders, 3 trapezoidal threads, 4 cylindrical shell nozzles, 5 lower cylinder bodys, 6 cylindrical shell imports.
Embodiment
As shown in drawings, the utility model is that one can produce high-intensity high-speed helical flow generating device in vertical tube, comprise lower cylinder body, upper cylinder, cylindrical shell nozzle, between upper lower cylinder body, connect by trapezoidal thread, the slurry spiral intensity that makes to dig up mine can regulate by connecting highly; At tangential uniform three cylindrical shell nozzles of the same circumference of lower cylinder body, while cylindrical shell outlet is 0.25 times of cylindrical shell import.
When use, cylindrical shell inlet is connected by flange with thick fluid pump, realizes pumping; On lower cylinder body, three high-speed jet cylindrical shell nozzles that are mutually 120 ° are along circumferentially (tangentially) jet simultaneously of lower cylinder body, and jet flow is fast rotational under the effect of tube wall, three bursts of jet stacks simultaneously, and form strong spiral flow with the stack of pumping axial flow; Cylindrical shell outlet port is connected with multistage slurry suction pump by flange, multistage pump aspirates strongly, because cylindrical shell outlet is 0.25 times of cylindrical shell import, causes slurry stream lifting speed to rise sharply, be approximately 4 times of left and right of cylindrical shell inlet speed, high-speed screw stream has produced like this in riser.
According to need of production, the utility model can work alone by separate unit, and slurry is raised after certain altitude, and spiral strength retrogression can add the spigot that continues and combine use, or reuse this device realize relay carry.
The utility model can be realized automation control, and, in the time that process control machine detects cylindrical shell outlet spiral insufficient strength, controller sends signal increases effluxvelocity, or improves suction pump pressure, or provides instruction adjustment cylindrical shell height.
The utility model not only can save energy reduction of discharging in a word, can also improve the working life of riser, and cost of production significantly reduces simultaneously, is worthy of popularization.
