Description
Technical field
The invention belongs to Pulse Power Techniques kata-rocks ore deposit fields, are specifically a kind of electrode structure crushed for rock ore deposit.
Background technology
Conventional method is crushed as Mechanical Method for rock ore deposit, is milled.This method requires the initial size of rock ore deposit,
Rock ore deposit particle needs are small to certain degree, could mill.Both need to pre-process rock ore deposit before milling.This pre- place
Reason majority is crushed also with Mechanical Method.Mechanical Method is there are inefficient, the problem of repeatedly processing is needed to rock ore deposit size.
And use high voltage pulse method processing rock ore deposit that need not then be pre-processed to rock ore deposit or only need simple bulk processing, but directly
Large volume of rock ore deposit can be crushed, until the particle of very little, and it is high with crushing efficiency, it is simple in structure,
The advantages that being adjusted flexibly.
The content of the invention
The purpose of the present invention is to provide a kind of high-voltage pulse kata-rocks ore deposit device, and the device is splendid attire ore container with putting
Integral structure is made in electrode, efficient to ore reduction, simple in structure.
The technical solution adopted is that：
A kind of high-voltage pulse kata-rocks ore deposit device, including cylindrical drum, support tube, high-field electrode and insulating cylinder, feature exists
In：
Insulating cylinder is bolted on pedestal, there is the sub- jack of voltage input terminal on pedestal and insulating cylinder bottom wall.
High-field electrode upper end is bullet, and high-field electrode has tapped centre bore.Locating sleeve is fixed on support tube bottom wall, it is high
In piezoelectricity pole lower part insertion positioning sleeve, support tube and high-field electrode are fixed on the bottom wall of insulating cylinder.High input voltage wire connection terminal
After the sub- jack of voltage input terminal on the bottom wall of pedestal and insulating cylinder, it is threadedly coupled with the centre bore of high-field electrode.
Cylindrical drum is arranged in insulating cylinder, and the lower end of cylindrical drum is supported by the support plate being located on the step on the inner wall of support tube upper end.
The upper end of cylindrical drum is fixed with ground wire wire connection terminal.The conical section of high-field electrode is stretched into cylindrical drum, and with cylindrical drum inner wall
Between have gap, gap size adjusts according to actual needs.
Above-mentioned cylindrical drum is ground electrode, leads to ground wire wire connection terminal and wired earth.High-field electrode is high-voltage pulse output terminal.
During broken rock and ore, ore to be broken is packed into cylindrical drum, while is added in insulating cylinder, support tube and cylindrical drum
Enter dielectric-water.The output terminal of high-field electrode and high voltage discharge circuit is connected using bolt type wire connection terminal, cylinder is described
Device is connected to ground.So in high-field electrode and cylindrical drum（Ground electrode）Between form voltage difference.When the voltage on high-field electrode
When reaching certain value, then discharge between high-field electrode and cylindrical drum.
When the rising edge of high voltage pulse is less than 500ns, electric discharge is happened at the inside of rock ore deposit in cylindrical drum container.In rock
Plasma channel is formed inside ore deposit, rock ore deposit is broken passage during expansion.Under conditions of repetition electric discharge, inside rock ore deposit repeatedly
Formed plasma channel, after multiple discharge between electrode and cylindrical drum, then can rock ore deposit from larger Particle Breakage to
The particle of very little.Short grained rock ore deposit is fallen into the annular groove of support tube.Final granular size is depended between electrode and cylindrical drum
The size in gap can as requested be adjusted gap size, and change corresponding pulse parameter.
Above-mentioned high-field electrode uses stainless steel or other metals for material.
The cylinder cylinder material of above-mentioned high voltage pulse kata-rocks ore deposit is stainless steel or other metals.
The support plate and insulation cylinder material of above-mentioned high voltage pulse kata-rocks ore deposit are nylon.
The bottom plate that above-mentioned high voltage pulse crushes is bakelite material or the insulating materials of other good economy performances.
Advantages of the present invention is：
The present invention integrates discharge electrode and container.It can also be used as the electrode of electric discharge and contain preparation
Broken rock ore deposit container.
The present invention being capable of preferable kata-rocks ore deposit under repetition discharge scenario.
The electrode size of the present invention can be adjusted according to rock ore deposit granular size, and overall structure is up-down structure, institute's duty
Between it is smaller.
The present invention has that crushing efficiency is high, simple in structure, easy to process, good economy performance compared to other rock ore deposit breakers
The advantages of.
