Abstract

The utility model provides a novel dust removing and recovering device, and belongs to the technical field of air cleaning. The novel dust removing and recovering device is that a protecting cover is welded on a charging bucket, and the parts where the periphery of the protecting cover is contacted with a sieve are of open type; the side edge of the bottom part of the protecting cover is connected with the upper side edge of the charging bucket; a hollow interlayer is formed at the top part of the charging bucket; and a pipeline is downwards connected from one side of the interlayer to a crusher. When sieving the materials, some of the leaked granules fall from the interlayer into the charging bucket under the effect of gravity and inertia, the rest of leaked granules are fed into the pipeline and then absorbed into the crusher together with the dust under the effect of air pressure, therefore, the degree of dust pollution in the working environment can be greatly reduced, the waste of the materials can be reduced as well, and lots of manpower, properties and time can be saved.

Description

A kind of novel dust removing retracting device

One, affiliated technical field

Belong to the air dust remover technical field, relate to a kind of for the gas solid separation retracting device on the disintegrating apparatus.

Two, background technology

Solid deduster is the general name of the class gas-separation machinery that extensively adopts in the industries such as chemical industry, metallurgy, cement, coal and gasification, environmental protection, particularly in to high-temperature flue gas the removing of solid particles, reclaim and play a part key.

Along with the raising of people's environmental consciousness and the development of science and technology, demand efficient, degree of depth dedusting improves constantly, Gu new efficient air-isolation technics and the corresponding cleaner of exploitation become the task of top priority.

My company is to produce polishing powder from rare earth as main, and in use there are a lot of problems in existing disintegrating machine loading hopper, and for example: dust discharge amount is very large, causes the working environment dust pollution serious, and the rate of recovery is low, causes the productive rate of product lower; Partial material is arranged from loading hopper to leaking outside during the sieve material, need to artificially collect, repeat broken dedusting operation, cause unnecessary waste etc.For dust pollution and the waste problem that existing charging (feeding) equipment exists, there is not on the market a kind of special dust seperator of suitable solution loading hopper problem at present, there are no relevant report yet.

Three, summary of the invention

The purpose of this utility model provides a kind of cleaner that is specifically designed on the disintegrating machine loading hopper, to reduce the post dust concentration, improves working environment, increases the rate of recovery, improves product yield, cuts the waste, and improves the efficient of deduster, increases its service life.

The technical solution of the utility model is: it comprises interlayer; screen cloth; loading hopper; flange; outer cover; elephant trunk; bend pipe; pipeline; make one deck protective cover in the outside of loading hopper; make open type in the position that contacts with screen cloth all around; the protective cover bottom margin links to each other with the top edges of loading hopper; make the interlayer of a hollow of top formation of loading hopper; under a side direction of interlayer, connect a device for cleaning pipeline to disintegrating machine; a granule materials part of missing during the sieve material is because gravity and inertia fall into loading hopper from interlayer; another part enters pipeline and dust one and coexists and be drawn into disintegrating machine under the Action of Wind pressure; greatly alleviated the dust pollution degree of post working environment; reduce simultaneously the waste of material, saved a large amount of manpowers; financial resources and time.

The utility model has solved the problem that original equipment exists, and utilizes original equipment transformation, designs a cover novel dust removing equipment, not only do not cause any burden, but also alleviated dust pollution, and avoided waste, also saved human and material resources, financial resources and time simultaneously.

Five, the specific embodiment:

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

Embodiment

At first, expand laterally certain space from the top of loading hopper 3 walls, weld together with the rectangular steel plates of four same sizes, form an outer cover 5, outer cover 5 bottoms and loading hopper 3 weld together, and make between the wall of itself and loading hopper 3 and form a hollow sandwich 1; Secondly, respectively open a rectangular breach at the wall of loading hopper 3, this mouth is upper to interlayer 1 top, down to the welding position of outer cover 5 with loading hopper 3, and the herringbone otch is made in the bottom, the a bit of distance of breach left and right sides Ge Liu, be used for placing four roof beams structure (figure does not indicate) of screen cloth 2, each roof beam structure all is positioned at each position, breach upper middle, when covering screen cloth 2, forms a rectangular gap between interlayer 1 and the loading hopper 3, like this, the material of missing during the sieve material just enters interlayer 1 from this rectangular opening position, falls at last loading hopper 3, has solved the leakage material problem of loading hopper 3.

If rely on merely inertia to make material enter loading hopper 3, also come with some shortcomings because material is Powdered, very light weight, so can not be very fast after entering interlayer 1 fall into loading hopper 3, have part can fly away in interlayer 1.Through repeatedly field observation and research, determine to utilize the air inlet of disintegrating machine (not indicating among the figure) to address this problem, its design is as follows:

Any side from the interlayer 1 of loading hopper 3, connect an elephant trunk 4 downwards, namely at elephant trunk 4 of loading hopper 3 outsides welding, doing a bend pipe 6 with the position of the horizontal level equal height of disintegrating machine (among the figure indicate) air inlet, elephant trunk 4 adopts welding manner to be connected with bend pipe 6, the other end connects the air inlet that a pipeline 7 leads to disintegrating machine, pipeline 7 is linked together by flange 8 with the disintegrating machine air inlet, after material enters elephant trunk 4, under Action of Wind pressure, be drawn into disintegrating machine, solved above problem.

The utility model working procedure is as follows:

1, opens successively the equipment run switch in broken post;

2, after equipment all starts, interior reinforced toward loading hopper 3, sieve material while feed in raw material, spill from screen cloth 2 edges

2, after equipment all starts, interior reinforced toward loading hopper 3, sieve material while feed in raw material, a material part that spills from screen cloth 2 edges falls in the loading hopper 3 from the interlayer 1 of deduster, another part falls into elephant trunk 4, and the suction function that produces by air-introduced machine is drawn in the disintegrating machine.

3, material is through crusher in crushing, by collecting in the material bag (indicating among the figure) after bag hose (indicating among the figure) filtration.

After using this deduster, the dust pollution that produces when reinforced obviously reduces, and working environment improves significantly.The material of missing obviously reduces, and has saved the step that manually regathers, and has reduced waste, has saved resource.

This utility model has reached requirement and the purpose of expection, and does not produce other problem, and practicality is very strong, can formally put into operation.
