Background
The float-sink experiment is mainly applied to the coal industry, the experiment needs a plurality of heavy liquids with different densities to carry out float separation on coal, so that the heavy liquids with different densities need to be added into a float-sink separator and recycled, and the heavy liquids with different density levels can not be mixed.
At present, research on coal floating and sinking experimental equipment is blank, in the prior floating and sinking experiment, floating coal is fished out from a net bottom barrel filled with coal in containers of various density levels by a manual method, heavy liquid for the density levels needs to be sequentially injected into a floating and sinking separator and recycled, and the heavy liquid of the density levels cannot be mixed.
When pouring into with retrieving heavy liquid, the prior art lets in a pipeline in every heavy liquid container, and every pipeline is equipped with a gas accuse ball valve, when needing which density level heavy liquid, corresponds which valve and opens, extracts heavy liquid through the diaphragm pump, and the same pipeline that needs to retrieve when retrieving heavy liquid, and every pipeline also is equipped with the gas accuse ball valve, also draws back heavy liquid through the diaphragm pump. Each of the above-mentioned pipelines requires a pneumatic ball valve, and the cost is too high due to the excessive number of ball valves.
The injection heavy liquid pipeline and the recovery heavy liquid pipeline are finally converged into a pipeline respectively, heavy liquid inevitably remains in the convergence pipeline of the injection pipeline when the heavy liquid is injected, and then the heavy liquid inevitably mixes with the remaining heavy liquid when the heavy liquid of the next density level is injected, so that the density of the heavy liquid is influenced. After a plurality of times of floating and sinking experiments, heavy liquid in each container can be greatly changed, and the accuracy of the floating and sinking experiments is influenced.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a heavy liquid diverging device of heavy liquid of different density grades is suitable for, does benefit to the heavy liquid diverging device of heavy liquid of different density grades of simplifying and float and sink experiment pipe-line system, avoiding.
In order to realize the above purpose, the utility model discloses a technical scheme be: a heavy liquid shunting device for a sink-float experiment comprises a valve sleeve and a rotary valve core positioned in an inner cavity of the valve sleeve, wherein a plurality of shunting channels are arranged around the valve sleeve, and a flow channel is communicated with the valve core; one end of the flow channel is in butt joint with the flow dividing channel, and the other end of the flow channel is used for connecting a pipe fitting or a pipeline.
Preferably, the valve core is connected with a driving source.
Preferably, the valve core is connected with a driving source through a speed reducer.
Preferably, the drive source is mounted to an end surface of the valve sleeve.
Preferably, the flow channel is L-shaped.
Preferably, the other end of the flow passage is connected with a main flow connecting pipe.
Preferably, the valve sleeve is polygonal, and the flow dividing channel is arranged on the side surface.
Preferably, the shunt passage is in threaded connection with the shunt nozzle.
Implement the utility model discloses technical scheme because a plurality of reposition of redundant personnel passageways are seted up to the valve barrel, and the reposition of redundant personnel passageway is convenient for with external pipe connection, when driving the valve core rotation, makes the case runner dock one of them arbitrary reposition of redundant personnel passageway, plays the reposition of redundant personnel effect that realizes each density level heavy liquid, has saved many sets of pipe-line system and on-off control valve quantity, can also avoid the mixture of heavy liquid.

Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 and fig. 2, the heavy liquid diversion device for the sink-float experiment mainly comprises a valve sleeve 8, a valve core 9, a motor 11 and a speed reducer 10.
The valve core 9 is a revolving body in shape, one end of the valve core 9 is connected with the motor 11 and the speed reducer 10 through keys, and the other end is provided with a flow passage communicated with the middle part of the revolving body of the valve core 9.
The valve sleeve 8 is a regular hexagonal prism, each surface of the hexagonal prism is provided with a shunt channel and communicated with the axis of the hexagonal prism, the shunt channel is provided with a shunt connector 5, and the shunt connector 5 is convenient to be connected with an external pipeline. The valve core 9 can make rotary motion on the valve sleeve 8 under the drive of the motor 11 and the speed reducer 10. The valve sleeve 8 and the valve core 9 are sealed by an upper skeleton sealing ring 7 and a lower skeleton sealing ring 7.
The end cover 4 presses the valve core 9 into the valve sleeve 8 and is connected with the valve sleeve 8 through a screw. The axle center of end cover 4 is opened has the through-hole, and the trompil end of case 9 is inlayed inside, and the through-hole of end cover 4 passes through threaded connection mainstream takeover 1 simultaneously, and the effect of mainstream takeover 1 is convenient for be connected with outside pipeline.
