The system additionally comprises a circulating pipeline (3). One end of the circulating pipeline (3) is connected with the concentration basin (1), the other end of the circulating pipeline (3) is connected with the pipeline (8) and a circulating pinch valve (4) is arranged on the circulating pipeline (3). The invention has the advantages that ore pulp with concentration lower than 68 percent can be delivered to the concentration basin for re-circulation through the circulating system, the low-concentration ore pulp is prevented from entering the agitation tank and affecting production and the production efficiency is effectively improved.
Description
Technical field
The invention belongs to the ore pulp transportation art, especially relate to the circulatory system in the ore pulp conveyance conduit.
Background technique
Before the line transportation ore pulp, be transported in the stirring chest after the ore pulp (concentration is lower than 68% ore pulp) of low density need being concentrated and stir, can occurring upstream choosing in process of production, to give birth to the ore deposit amount little, cause the deckered stock chest pulp concentration low, thereby the ore pulp that concentrates does not reach the design concentration requirement, can not be transported in the stirring chest, final influence is produced.For this reason, need a kind of Circulation pipe of invention system, thoroughly solve this type of problem.
Summary of the invention
The invention provides the circulatory system in a kind of ore pulp conveyance conduit, the technical problem of its solution is to make the ore pulp of low density can carry out concentrating once more, thoroughly solves the low density ore pulp and enters stirring chest and cause transfer ore pulp not reach the designing requirement problem.
The present invention specifically discloses the circulatory system in a kind of ore slurry pipeline, comprise deckered stock chest, underflow pump, densitometer, stirring chest and stir pipe clip valve, described deckered stock chest is connected with described stirring chest by pipeline, above-mentioned densitometer is set on pipeline, position at the close stirring chest of pipeline is provided with above-mentioned stirring pipe clip valve, also comprises circulation loop, and the one end connects deckered stock chest, the other end is connected on the pipeline, and described circulation loop is provided with the circulation pipe clip valve.
Wherein, described stirring pipe clip valve is arranged on the stirring chest upper end, and the other end of described circulation loop is connected on the pipeline, between densitometer and stirring pipe clip valve.
Further, the ore pulp in the described deckered stock chest pressurizes the back by described line transportation by described underflow pump.The pulp concentration of measuring when described densitometer is closed described circulation pipe clip valve more than or equal to 68% the time, opens described stirring pipe clip valve.When pulp concentration less than 68% the time, open described circulation pipe clip valve, described stirring pipe clip valve can be in open mode, also can be in closed condition.
The invention also discloses and adopt the above-mentioned circulatory system to carry out the method that ore pulp is carried, it is characterized in that:
Ore pulp in the described deckered stock chest pressurizes the back by described line transportation by described underflow pump;
Described densitometer carries out measurement of concetration to the ore pulp of carrying;
When detecting pulp concentration more than or equal to 68% the time, close described circulation pipe clip valve, guarantee that described stirring pipe clip valve is in open mode, ore pulp directly is delivered to described stirring chest;
When pulp concentration less than 68% the time, open described circulation pipe clip valve, make ore pulp enter described deckered stock chest and carry out concentrating once more by described circulation loop.
The present invention can not reach concentration 68% ore pulp and is transported to deckered stock chest by the circulatory system and circulates once more, has avoided the low density ore pulp directly to enter stirring chest and influence production, has improved manufacturing efficiency effectively.
