But no improvement was made to the feed tube.

The Chinese utility model patent (CN208345300U) discloses a limestone feeding system, which comprises a first bin, a first feeder and a boiler, wherein a discharge port of the first bin is connected with a feeding port of the first feeder through a first feed conveying pipe, and a discharge port of the first feeder is connected with a feeding port of the boiler through a second feed conveying pipe; the boiler is characterized by further comprising a second storage bin and a second feeder, wherein a discharge port of the second storage bin is connected with a feeding port of the second feeder through a third conveying pipe, and a discharge port of the second feeder is connected with a feeding port of the boiler through a fourth conveying pipe. The utility model discloses a solve current lime stone feed system and broke down, when manual parking overhauld, because the coal fired boiler is still operating to there is not reserve circuit, probably causes SO in a period₂The content exceeds the standard and can not meet the requirement of environmental protection. But no corresponding improvement is made to the feeding pipe.

In the prior art, in the limestone silo, sundries are easy to enter the silo in the daily operation process, so that the feeder is frequently jammed, the problems of standard exceeding of environmental protection indexes and the like are caused. In addition, in the prior art, the arc length part of the elbow of the feeding pipe is too short, so that the materials are seriously scoured and abraded, leakage frequently occurs, and the field dust raising and equipment dust deposition are serious; and among the prior art limestone material level difficult to survey, the storehouse body does not generally have visual charge level indicator, and daily detection can only personnel scramble to the top of the storehouse (15 meters) and use the rope to carry out the roughly position detection of material, causes personnel tired out, and the detection result is inaccurate. Therefore, the limestone feeding pipe which is not easy to wear, firm and durable is provided, and great practical significance is achieved.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a lime stone material loading pipe, to among the background art lime stone material loading pipe unobstructed debris filter screen, material loading pipe elbow arc length portion short and lime stone material level be difficult to survey the scheduling problem, provide a difficult wearing and tearing, durable lime stone material loading pipe of durable.

In order to solve the technical problem, the utility model provides a limestone feeding pipe, which comprises a feeding hole, a filter screen, a first elbow, a second elbow, an arc long part and a material detector; the filter screen is connected with material loading mouth department pipeline, the filter screen passes through the pipe connection with first elbow, first elbow passes through arc length portion with the second elbow and is connected, the second elbow is connected with the limestone storehouse.

The to-be-solved technical problem of the utility model can also be further realized through following technical scheme, circular platelike structure is chooseed for use to the filter screen, evenly sets up the through-hole on the circular slab surface.

The to-be-solved technical problem of the utility model can also be further realized through following technical scheme, first elbow and second elbow length are 1030 mm.

The to-be-solved technical problem of the utility model can also be further realized through following technical scheme, the export of second elbow is established and is put at limestone storehouse central point.

The to-be-solved technical problem of the utility model can also be further realized through following technical scheme, arc length portion length is 1000 mm.

The to-be-solved technical problem of the utility model can also be further realized through following technical scheme, visit the material ware including rocking wheel and visit the material rope.

Compared with the prior art, the beneficial effects of the utility model are that:

(1) after the filter screen is additionally arranged, sundries are effectively prevented from entering the limestone bin, and the environment-friendly parameter exceeding standard caused by the jamming of the limestone feeder is avoided;

(2) the arc length part is lengthened, the force of the materials to wash the pipe wall is reduced, and the service life is prolonged;

(3) the length of the elbow is lengthened, the outlet of the second elbow is changed to the central position of the limestone bin body, and the material is effectively prevented from deviating from one side during feeding;

(4) the automatic design is provided with the detector, the automatic material level detector has the characteristics of time saving, labor saving and accurate measurement, and operators can detect accurate material levels on the spot, so that the working efficiency is greatly improved.
