Description

Utilize high-velocity jets to carry the device of mine tailing

Technical field

The utility model discloses a kind of device that utilizes high-velocity jets to carry mine tailing, belong to mine tailing actual mining technology field more on a large scale.

Background technology

At present, promote the airlift of mine tailing, and effectively overcome the cost height that existing other process for stoping exist though occurred utilizing air to be used as power, easy to wear, be difficult for the long-time continuous operation, production efficiency is hanged down and is waited all shortcomings.But the principle of airlift is to utilize the density ratio neat liquid of gas-liquid mixture low; Rely on the device of similar permeator that mine tailing is upwards promoted; Be to utilize buoyancy frankly speaking with the floating water surface of going up of gas-liquid mixture; This method unit time carries the amount of mine tailing less, because gas speed to float in water was exactly limited originally, can not satisfy the needs of extensive back production and comprehensive application mine tailing; And existing lifting means generally all is a bevelled, can not accomplish fully that vertically, significant impact is caused to the efficient that promotes undoubtedly in this inclination angle.Because bubble is vertical uplift all the time, if raising pipe tilts, the inevitable the first half that all concentrates on pipeline of bubble, as shown in Figure 1, cause the hoisting force that has only half the liquid to obtain bubble in the whole pipe.Liquid because there is difference of pressure in two parts up and down, is refluxed down by the latter half again after being raised up to electrolyte level by the first half of raising pipe, and so, the lifting efficient of whole pipe is drop by half at least; In addition, the throughput of lifter is not The more the better, neither be few more good more; If bubble concentrates on the first half of raising pipe entirely, certainly will cause the throughput of the first half too much so, the latter half is then not enough; The result is exactly best throughputs of out of reach of two parts, and efficient further reduces.

Summary of the invention

The utility model discloses a kind of device that utilizes high-velocity jets to carry mine tailing, and the mine tailing transport efficiency that has overcome existing airlift process for stoping existence is low, can not satisfy the shortcoming of extensive back production needs.

The utility model utilizes high-velocity jets to carry the device of mine tailingIt is characterized in that: adopting the back production ship is apparatus carriers; The midbody structure is " recessed " font, and the crack hinge in the middle of " recessed " font is connected with the hank tool arm, is connected with hull through hawser; Can control it through the hawser jacking system of hull and go up and down, thus the back production degree of depth of control total system; It is characterized in that: raising pipe and breather pipe parallelization are on the reamer arm; The head of reamer arm has a jet pump, and the working fluid pipe of jet pump is connected with raising pipe with breather pipe respectively with diffuser pipe, and the jet pump front is a suction inlet; Suction inlet links to each other with the sucked liquid pipe of jet pump; Also have a reamer to be connected with the reamer arm below the suction inlet, a top control cock of series connection of breather pipe also connects air pump and storage tank, and raising pipe top then puts in cobber.

In the utility model, the jet feedway is according to producing negative pressure around the swiftly flowing liquid, with around the liquid that is raised of needs attract and give certain kinetic energy, it is transported to the process of target location.Like Fig. 2, jet is carried and is divided into 3 processes:

1. high pressure air gets into the working fluid pipe, sprays at a high speed from nozzle afterwards.

2. because the injection of high-speed gas descends jet chamber pressure on every side rapidly, sucked liquid sucks the jet chambeies through sucked liquid pipe 16

3. sucked liquid is inhaled into after the jet chamber, is taken away by swiftly flowing air, forms gas-liquid mixture; The action amount of going forward side by side exchange; The kinetic energy that is transferred fluid is increased,, get into diffuser pipe then from the trunnion ejection; Convert most of kinetic energy into the pressure ability through diffuser pipe at last, be delivered to the target location.

The good effect of the utility model is: according to producing principle of negative pressure around the swiftly flowing liquid; Through the jet feedway will around the liquid that is raised of needs attract and give certain kinetic energy; It is transported to the target location; The mine tailing transport efficiency promotes greatly, can satisfy the needs of extensive mine tailing back production, and is simple in structure, easy to operate.

The specific embodiment

According to Fig. 2, shown in Figure 3; It is apparatus carriers that the utility model adopts the hull 18 of back production ship; Hull 18 central structures are " recessed " font, and the crack hinge in the middle of " recessed " font is connected with hank tool arm 7, is connected with hull 18 through hawser 5; Can control it through the hawser jacking system on the hull 18 and go up and down, thus the back production degree of depth of control total system; Raising pipe 4 and breather pipe 6 parallelizations are on reamer arm 7; The head of reamer arm 7 has a jet pump 3, and the working fluid pipe 17 of jet pump 3 is connected with raising pipe 4 with breather pipe 6 respectively with diffuser pipe 12, and jet pump 3 fronts are suction inlets 2; Suction inlet 2 links to each other with the sucked liquid pipe 16 of jet pump 3; Also have a reamer 1 to be connected with reamer arm 7 below the suction inlet 2, a top control cock 8 of series connection of breather pipe 6 also connects air pump 10 and storage tank 9, and raising pipe 4 tops then put in cobber 11.

During the work of the utility model device, the head of reamer arm 7 is put into mine tailing bottom of the reservior portion through hawser 5, and at this moment, reamer 1 rotates, and mud is stirred, and around suction inlet 2, forms the miscible zone that an ore in sand form and water are formed, so that suction inlet absorbs ore pulp; Air pump 10 runnings simultaneously are pressed into the jet pump 3 of raising pipe head with air through breather pipe 6, in order to make steady air current, should connect a storage tank 9 on the breather pipe 6, the control cock 8 of also connecting; Air gets into jet pump 3 through working fluid pipe 17, in jet pump 3, from nozzle 14 ejection at a high speed; Jet chamber 15 in-to-in pressure are descended rapidly, and ore pulp successively is inhaled into jet chamber 15 through suction inlet 2 and sucked liquid pipe 16, is taken away by swiftly flowing air afterwards; Form gas-liquid mixture, the action amount of going forward side by side exchange increases the kinetic energy of ore pulp; From trunnion 13 ejections, get into diffuser pipe 12 then, converting most of kinetic energy into pressure in diffuser pipe 12 can; Upwards promote through raising pipe 4 at last, get into cobber 11 at last and carry out ore-dressing practice.
