Abstract
The utility model provides a material guide pipe facilitating powder material recycling. The lower portion of the returned powder material guide pipe is sealed relatively, materials can be recycled conveniently, and particle scattering and leakage and environment pollution are avoided. The material guide pipe comprises an inclined material guide pipe body. A powdered material collection hopper is arranged at the top of the material guide pipe body, a vertical discharging section is arranged at the bottom, a baffle of a planar structure is inserted into the inclination section on the lower portion of the material guide pipe, an air hole is formed in the upper portion of the baffle, and a powdered material discharging hole is formed in the bottom of the baffle. An abrasion resistant layer covers the surface of the inner side of the baffle.
Description
Technical field
The utility model relates to iron and steel metallurgical industry powder reclaiming device, is specifically related to a kind of passage that powder reclaims of being convenient to.
Background technology
At present, when blast furnace process, be to ensure permeability to air in stove, reduce pressure reduction, the granularity that enters furnace charge be there are certain requirements, be generally to reduce the powder that furnace charge that diameter is less than 10mm enters stove ratio and stop to be less than 5mm to enter stove.In blast furnace production process, will produce a large amount of dust and granule, this dust and granule need to reclaim by recovery system for this reason.Dust under conventional powder recovery system structure sieve directly drops on back powder belt by back powder passage, causes powder to spill and airborne dust, causes site environment to pollute, and affects the health of operating personal.Although can solve by strengthening the air quantity of dedusting fan the problem of dust pollution, be to be open design due to passage bottom, dust removal ability is limited, can not fundamentally solve airborne dust and powder spills problem, and causes the waste of fan delivery.
Summary of the invention
For above-mentioned technical matters, the utility model provides a kind of passage that powder reclaims of being convenient to, and back powder passage bottom is sealed relatively, is not only convenient to recovered material, also can avoid powder to spill and environmental pollution.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of passage of being convenient to powder recovery, comprise the passage body that tilts to install, passage bodies top is provided with powder collection bucket, bottom is provided with vertical discharging section, passage lower tilt section is fitted with the baffle plate of planar structure, baffle plate top offers air extractor vent, and baffle plate bottom is provided with powder discharge orifice.
As further restriction of the present utility model, described baffle plate inner surface is covered with wearing layer.
In technique scheme, described wearing layer is ceramic material layer.
In technique scheme, described wearing layer local or cover except air extractor vent and powder discharge orifice position at baffle plate inner surface comprehensively.
In technique scheme, described air extractor vent is shaped as rectangle or circle.
As further restriction of the present utility model, described air extractor vent is arranged on baffle plate top 3/4 ~ 1/2 height and position.
In technique scheme, described powder discharge orifice be shaped as rectangle or circle.
As further restriction of the present utility model, the height of described powder discharge orifice is height of baffle plate 1/10 ~ 1/8.
The beneficial effects of the utility model are according to known to the narration of such scheme:
Adopt the passage of said structure, by baffle plate, large area sealing is carried out in passage bottom, on baffle plate, only retain air extractor vent and powder discharge orifice, passage can be sealed relatively, top dedusting fan is reclaimed dust effectively, reduce the loss of dedusting air quantity; Meanwhile, can slow down material stream descending speed, returning charge can be fallen on back powder belt slowly, avoid in former back powder passage powder to concentrate and fall, cause and spread, leak phenomenon; And baffle plate inner surface is covered with wearing layer, can effectively improve plate washer service life.
Brief description of the drawings
Fig. 1 is the passage mounting structure schematic diagram of the utility model embodiment;
Fig. 2 is the baffle arrangement schematic diagram of the utility model embodiment;
Fig. 3 is the section-drawing of Fig. 2;
In figure, be labeled as: 1, passage body; 2, baffle plate; 3, belt; 4, air extractor vent; 5, powder discharge orifice; 6, wearing layer; 1-1, powder collection bucket; 1-2, discharging section.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
As shown in drawings, a kind of passage of being convenient to powder recovery, comprise the passage body 1 that tilts to install, passage body 1 top is provided with powder collection bucket 1-1, bottom is provided with vertical discharging section 1-2, passage lower tilt section is fitted with the baffle plate 2 of planar structure, baffle plate 2 tops are positioned at outside passage body 1 and both sides are provided with the ear that prevents its landing, and baffle plate 2 tops that are positioned at passage body 1 offer air extractor vent 4, and baffle plate 2 bottoms are provided with powder discharge orifice 5.
In the present embodiment, described baffle plate 2 inner surfaces are covered with wearing layer 6, and described wearing layer 6 is ceramic material layer.
In technique scheme, described wearing layer 6 covers part except air extractor vent 4 and powder discharge orifice 5 positions at baffle plate 2 inner surfaces.
In technique scheme, described air extractor vent 4 is shaped as rectangle, and air extractor vent 4 is arranged on baffle plate 2 top 3/4 height and positions.
In technique scheme, described powder discharge orifice 5 be shaped as rectangle, the height of described powder discharge orifice 5 is 1/10 of baffle plate 2 height.
The utility model seals passage bottom large area by plate washer, tiny dust granules is siphoned away by dedusting wind by air extractor vent 4, powder can only be discharged by powder discharge orifice 5, and slowly fall on back powder belt 3, in the time that increasing suddenly, powder amount also can carry out overflow by the air extractor vent on baffle plate 2 tops 4, improve dust removing effects and reduce the waste of dedusting air quantity thereby reach, and reduce the effect of environmental pollution.
In above-described embodiment, preferred embodiments of the present utility model is described, obviously, under inventive concept of the present utility model, still can make a lot of variations.At this, should illustrate, any change of making under inventive concept of the present utility model all will fall in protection domain of the present utility model.
