Technical Field

The utility model belongs to the technical field of the auxiliary assembly of coal preparation plant, specifically indicate a stifled device is prevented to shale shaker undersize funnel.

Background

The vibrating screen is common dewatering equipment in a coal preparation plant, but in the using process, once a screen plate falls off to cause sundries to enter an undersize funnel, the sundries are difficult to be found in time, after the sundries are found, the sundries are accumulated, and long time is needed for cleaning a large amount of sundries accumulated in the undersize funnel, so that normal production is influenced; and if the discovery is not timely, a large amount of oversize debris can directly get into the pipeline through the hopper under the screen, block up the pipeline, can block up the pump even, seriously influence normal production. Therefore, it is imperative to research a device for timely finding the blockage of the undersize funnel.

Disclosure of Invention

The utility model discloses to prior art's is not enough, provides a stifled device is prevented to funnel under shale shaker sieve, can in time discover the funnel and block up, is convenient for in time take and prevents stifled measure.

The utility model discloses a following technical scheme realizes, provides a stifled device is prevented to shale shaker undersize funnel, including the overflow pipe that is located the funnel with set firmly the comb body in the overflow pipe upper end, the lower extreme of overflow pipe and the sealed rigid coupling in upper end of discharging pipe wear to be equipped with honeycomb duct I on the lateral wall of funnel, honeycomb duct I extends the one end in the funnel and is higher than the upper end of overflow pipe, and the one end below that honeycomb duct I stretches out the funnel is equipped with rare medium bucket.

According to the scheme, the overflow pipe is arranged, so that the outflow height of liquid is increased, even if sundries fall around the sieve plate, the sundries can fall to the grate body or the periphery of the overflow pipe under the action of gravity, and the blockage of the hopper under the sieve is avoided; through setting up honeycomb duct I, when the overflow pipe upper shed was blockked up, the liquid level rose, and liquid rises to a take the altitude after, and liquid flows out from honeycomb duct I to make things convenient for the staff to observe, through setting up the rare bucket of mediating, be convenient for collect overflowing liquid.

As optimization, install flow sensor I on the honeycomb duct I, I electric connection alarm device of flow sensor. This optimization scheme is through installing flow sensor I on honeycomb duct I, and when there was liquid to flow through flow sensor I, the signal trigger alarm device of flow sensor transmission reminded for the staff, has improved the promptness of discovery jam.

As optimization, still wear to be equipped with honeycomb duct II on the lateral wall of funnel, honeycomb duct II extends the one end that the one end in the funnel is higher than honeycomb duct I and extends the one end in the funnel, and honeycomb duct II stretches out the one end of funnel and is located rare and mediate the bucket top. This optimization scheme is through setting up honeycomb duct II, if I overflows in honeycomb duct not in time by the discovery, through the outflow of II well liquid of honeycomb duct, increases the sound of reminding.

And optimally, a flow sensor II is installed on the flow guide pipe II, and the flow sensor II is electrically connected with the vibrating screen driving device. This optimization scheme's setting, when having liquid flow through flow sensor II, flow sensor II's signal passes to shale shaker drive arrangement, conveniently controls the shale shaker and in time shuts down to it aggravates to block up.

As optimizing, honeycomb duct I and honeycomb duct II all are including violently managing and the standpipe that is linked together, violently manage and pass the funnel lateral wall and with the sealed rigid coupling of funnel lateral wall, standpipe upper end and violently union coupling, the standpipe lower extreme extends to the rare and mediumly bucket top. The flow guide pipe I and the flow guide pipe II of the optimized scheme are both inverted L-shaped, and the flow guide pipe is simple in structure and convenient to manufacture.

As optimization, one end of the draft tube I extending into the funnel is 500-600 mm higher than the upper end face of the overflow tube. The height difference setting of this optimization scheme has guaranteed the normal liquid storage capacity of funnel, and liquid spills over when avoiding normal use state.

As optimization, the upper end face of the overflow pipe is 200-300 mm higher than the bottom of the funnel. The height difference setting of the optimization scheme provides sufficient time for the operation personnel to adopt measures, and avoids triggering the flow sensor II in the processing process after alarming.

The utility model has the advantages that: through setting up the honeycomb duct that the high position is different to and the flow sensor who installs respectively in two honeycomb ducts, in time report to the police when the funnel blocks up, the staff of being convenient for in time discovers and handles to prevent the accident and further enlarge.
