Abstract

An airflow method and apparatus for discharging ore from wet horizontal centrifugal ore dresser are disclosed. Said apparatus is composed of rotary drum, casing, ore feeding pipe, water supplying tube, high-pressure airflow spraying pipe and machine frame. Its advantage is low water consumption.

Description

The air-flow ore discharge method and the device of centrifugal ore separator
Affiliated technical field
The invention belongs to the horizontal centrifugal ore separator of wet type and discharge the method and the device of concentrate, more particularly, it relates to concentrate is discharged in the winding-up effect that utilizes high pressure draught from horizontal centrifugal ore separator method and device.
Background technology
All drum-type centrifugal ore separators, mine tailing can successfully be discharged automatically, does not have problems substantially.Concentrate is close on the drum inner wall owing to powerful action of centrifugal force and can't discharges automatically only.Thereby the automatically continuous ore discharge problem of solution concentrate, always be the key of successfully developing the drum-type centrifugal ore separator.
According to drum rotating axis and horizontal relation of plane, centrifugal ore separator can be divided into horizontal and vertical two types: be called horizontal centrifugal ore separator if the axis of rotary drum is parallel with horizontal plane; Be called the vertical centrifugal ore separators if the axis of rotary drum is vertical with horizontal plane.The invention belongs to horizontal centrifugal ore separator.As the representative of horizontal centrifugal ore separator, domestic have cloud tin formula centrifugal ore separator, SL type jet and centrifugal ore separators and an adverse current platoon centrifugal ore separator; The many times of gravity concentrators (MGS) of Britain etc. are abroad arranged.Cloud tin formula centrifugal ore separator can not turn round continuously, can only be interrupted to the ore deposit and utilizes flushing water to discharge concentrate, and energy consumption and water consumption are all high, and existing hexyl is originally stopped using.SL jet and centrifugal ore separators and adverse current platoon centrifugal ore separator all are to utilize plus high-pressure water spray on the basis of cloud tin formula centrifugal ore separator, and the concentrate that will be deposited on drum inner wall by the impulse force of water under high pressure is gone out rotary drum and realized continuous ore discharge.Though they have solved the continuous ore discharge problem of concentrate, but still, fail so far extensively to promote the use of because water consumption, energy consumption height, economic effect are not good, must add shortcomings such as water purification installation and mechanical stability be relatively poor for preventing to stop up the High-Pressure Water mouth of pipe.The concentrate discharge mode of many times of gravity concentrators (MGS) is to adopt the mechanical type scraper plate to scrape, and it is bigger to make that device structure complexity, scraper plate wear and tear, and costs an arm and a leg.Maximum innovation part of the present invention is the above-mentioned High-Pressure Water that is used to arrange concentrate is changed into high pressure draught, not only can realize the smooth discharge of concentrate, and overcome many shortcomings of arranging concentrate with High-Pressure Water.
Summary of the invention
The present invention seeks to realize utilizing high pressure draught from centrifugal ore separator, to discharge the method and the device of concentrate; it not only can realize discharging continuously smoothly of concentrate, and can be according to the requirement of different sorting material character, under non-stop-machine situation; press the concentrate enrichment degree, be interrupted and discharge.
For achieving the above object, the invention provides the air-flow ore discharge method of centrifugal ore separator, it is characterized in that by air pressure intensity being that the winding-up effect of 0.4~0.6Mpa high pressure draught is discharged centrifugal ore separator with the heavy mineral adverse current.
According to the centrifugal ore separator air-flow ore discharge device of the above method design, comprise rotary drum 2 and the casing of fixing with frame 93, the air-flow jet pipe 6 that puts in the rotary drum 2 is installed on the described casing 3.
Operation principle of the present invention is that ore pulp under the synergy of centrifugal force and flow of slurry film, is realized the separation of weight mineral after feeding rotary drum to the ore deposit mouth.Light mineral is discharged with ore deposit stream automatically as mine tailing; The heavy mineral that is attached on the rotatory drum wall flows to motion in the winding-up effect subinverse ore deposit of the high pressure draught of high pressure draught nozzle ejection, and discharging from the concentrate outlet becomes concentrate, finishes assorting room.Because the present invention discharges concentrate by the winding-up effect of high pressure draught, so be called the air-flow ore discharge method and the device of centrifugal ore separator.
The present invention carries out adverse current as pressure-air and discharges the centrifugal ore separator of concentrate and compare with existing similar technology and have following advantage:
(1) discharges concentrate and replace High-Pressure Water, economize on resources, reduce cost with pressure-air.Air can directly be taken from atmosphere, neither needs to add purifier, does not also need to recycle and recycle, inexhaustible, and the process that sorts is not polluted air, therefore both save great amount of water resources, reduced production cost again, easy to implement;
(2) the present invention not only can discharge concentrate continuously, also can give the ore deposit continuously under non-stop-machine situation, and according to the needs of sorting material concentrate enrichment time, the jet time of control high pressure draught is interrupted and discharges concentrate;
(3) blowing direction of high pressure draught air nozzle can be regulated, to improve the effect of sorting;
(4) the present invention can be used for the transformation of existing drum-type centrifugal ore separator.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
The specific embodiment
Label among Fig. 1 is motor 1, rotary drum 2, casing 3, mineral-feeding pipe 4, washing pipe 5, air-flow jet pipe 6, concentrate mine-carrying groove 7, mine tailing mine-carrying groove 8, frame 9, universal joint 10 and universal bearing 11, air pressure regulator 12.
Thereby motor 1 drive transmission device drives rotary drum 2 around the horizontal axis revolution, and the raw ore ore pulp enters rotary drum 2 inwalls through mineral-feeding pipe 4, carries out layering and sorting under the synergy of centrifugal force and gravity; Washing pipe 5 is fixed on the frame 9; The bolster of high pressure draught jet pipe 6 connects with the tuning axle by universal joint 10, and universal socket 11 is fixed on the frame 9, and forms revolute pair with the tuning axle.Through air-flow jet pipe 6 air-flow pressure is 0.4Mpa; it both can have been jetted continuously concentrate had been discharged, and also can not shut down and give under the condition of ore deposit continuously according to the needs of concentrate enrichment and sorting; control air compressor output valve sprays high pressure draught discontinuously and is interrupted the discharge concentrate.High pressure draught jet pipe 6 both can have been fixed a blowing direction and discharge concentrate, also can regulate air-flow jet pipe 6 winding-up angle and directions by the regulating shaft 16 of universal joint 10 as required; Jetted to the concentrate of the end, chassis of rotary drum 2 by high pressure draught, discharged by the concentrate gape of end, chassis and enter concentrate receiving slit 7 and become concentrate, mine tailing then following current becomes mine tailing in mine tailing receiving slit 8.Raw ore constantly feeds, and the concentrate and tailings after the sorting is constantly discharged, and whole assorting room is not shut down, carried out continuously.When concentrate grade is had relatively high expectations, can the temporary close air-compressor valve, allow its enrichment a period of time, wait to reach predetermined grade after, open valve again and carry out ore discharge.
In order to improve the ore dressing effect, in the process of sorting, can add some water in right amount with washing pipe 5 and give ore pulp according to pulp density.
