Abstract
The invention discloses the lower dielectric film filter method of block spoil sieve and device, relate to spoil de-mediated recovery technology field in dense medium washing process, when solving the bucket position of existing recovery system existence, density instability, adjustment difficulty, the problem that product ash content is restive.A kind of lower dielectric film filter method of block spoil sieve, comprises the following steps: block raw coal sieves after dehydration de-mediated through spoil, and spoil sieve is lower closes medium and rare medium feeding baffle-box; Conjunction medium in baffle-box is sent into by pipeline and is closed Jie's bucket, and rare medium sends into rare Jie's bucket by pipeline; Rare medium in rare Jie's bucket is by recovering medium after pump and magnetic separator effect.The present invention can substantially increase the bucket position of two systems in production process, density equalization, stability; Production system controls automation more, more flexibly; More convenient to operate, more simply.
Description
Technical field
The present invention relates to spoil de-mediated recovery technology field in dense medium washing process, be specifically related to the lower dielectric film filter method of block spoil sieve and device.
Background technology
Existing spoil de-mediated recovering medium device, spoil sieve below by 4 pipelines which is provided with valve respectively Jie bucket rare with 4 be connected, rare Jie's bucket has two cover dielectric film filter systems, i.e. two pumps, two magnetic separators.Under normal circumstances, a system recoveries medium given by pump, a magnetic separator, and other pump, magnetic separator are to two system recovering medium.
In actual production, adopt old bucket position, density adjustment mode, occurred following problem:
One, when a system and two system bucket position, density occur unbalanced, time unstable, adjust pole and be not easy, especially when new and old rare Jie's bucket respectively has set of system to start shooting, bucket position, density are more unstable, result in product ash content restive;
Two, on pipeline, valve is more, and worker operates extremely inconvenient.
Summary of the invention
The present invention be in order to solve bucket position that existing recovery system exists, density unstable time, adjustment difficulty, the problem that product ash content is restive, and provide the lower dielectric film filter method of a kind of block spoil sieve and device.
The present invention is achieved by the following technical solutions:
A kind of lower dielectric film filter method of block spoil sieve, comprises the following steps:
(1) block raw coal is after spoil sieve dehydration de-mediated, and spoil sieve lower conjunction medium and rare medium send into baffle-box;
(2) the conjunction medium in baffle-box is sent into by pipeline and is closed Jie's bucket, and rare medium sends into rare Jie's bucket by pipeline;
(3) the rare medium in rare Jie's bucket is by recovering medium after pump and magnetic separator effect.
Above-mentioned recovery method, carry out in medium recovery device under block spoil sieve, the lower medium recovery device of described block spoil sieve comprises spoil sieve, baffle-box, conjunction Jie bucket, rare Jie's bucket, two pumps, two magnetic separators, baffle-box introduced by the lower installation of spoil sieve two pipelines, introduce two rare Jie's buckets and two by pipeline under baffle-box and close Jie's buckets, two rare Jie's buckets close Jie's bucket respectively by a pump and a magnetic separator be connected with one again.
Further, described baffle-box is of a size of 800mm*800mm*1000mm.
The pipeline twice of rare Jie of the connection under described baffle-box bucket is provided with the remote controlled Pneumatic automatic control valve of central station of floating dock.
Compared with prior art, the present invention has the following advantages:
(1) the bucket position of two systems in production process, density equalization, stability can be substantially increased;
(2) production system controls automation more, more flexibly;
(3) more convenient to operate, more simply.
