Structure, ratio, size depicted in Figure of description etc., only to coordinate the revealed content of specification, with Understand for those skilled in the art and read, be not limited to the enforceable qualifications of the utility model, therefore do not have skill Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size, are not influencing the utility model institute Under the effect of producing and the purpose that can reach, the model that can cover in the revealed technology contents of the utility model should all be fallen In enclosing.Meanwhile cited such as " on ", " under ", "front", "rear", " centre " term in this specification, it is merely convenient to describe Understand, and be not used to limit the enforceable scope of the utility model, its relativeness is altered or modified, without substantive change Under technology contents, when being also considered as the enforceable category of the utility model.
The utility model is a kind of steelmaking ingredient drying unit, and the steelmaking ingredient is generally spherical combustion-supporting material, is led to Cross and it is dried, and then prevent the rupture of auxiliary material, and sound is quick-fried in stove, influences to produce.The utility model is fired with high temperature Burn tail gas as medium carry out high efficiency drying, and as much as possible reduce be molded steelmaking ingredient percentage of damage, meet it is daily into Product export yield.
As Figure 1-Figure 5, the present apparatus includes vertical cylinder 1, and the lower end of the cylinder 1 is funnel structure 2, infundibular ganglion The bottom of structure 2 is equipped with discharge port 21, and steelmaking ingredient is put into from 1 top of cylinder, is exported after drying through discharge port 21.The cylinder 1 side wall is equipped with interlayer 11, and the outside of cylinder 1 is equipped with the air inlet 12 connected with interlayer 11.It is equipped with the inner cavity 13 of the cylinder 1 The more horizontal guide ducts 3 connected with interlayer 11, have been respectively communicated with vertical guide duct 4 on every horizontal guide duct 3, described vertical Having multiple first air ports 41 on guide duct 4, the centre position of the inner cavity 13 is equipped with vertical blast main 5, and at least one A transverse direction guide duct 3 is connected with blast main 5, and the blast main 5 is equipped with upper cover 51, is vertically equipped with the blast main 5 more The umbrella wind deflector 6 that a edge tilts down, the blast main 5 have on the position between adjacent wind deflector 6 Two air ports 52.
The operation principle of the present apparatus is：In use, by high-voltage explosion-proof wind turbine, the high-temperature tail gas after flame combustion is introduced Flame fades off thermal energy output device, first removes naked light and allocates to suitable temperature, then is passed through by the drainage of high-voltage explosion-proof wind turbine Air inlet 12 forces the interlayer 11 of the press-in present apparatus.Hot wind is introduced into horizontal guide duct 3 by interlayer 11, in horizontal guide duct 3 Hot wind fraction enter vertical guide duct 4, it is most of to enter blast main 5.Hot wind into vertical guide duct 4 passes through the first wind Mouth 41 is discharged into inner cavity 13, it is used for the auxiliary material heating, drying that steelmaking ingredient overstocks area.Pass through second into the hot wind in blast main 5 Air port 52 is discharged, i.e., has hot gas to be forced out between adjacent wind deflector 6, accumulation is covered on wind deflector 6 and in inner cavity 13 The steelmaking ingredient in portion region is uniformly dried.The present apparatus can accomplish to be evenly heated the buying securities with all one's capital of steelmaking ingredient, isobaric, isothermal Drying.While carrying out heating to steelmaking ingredient and drying, because the air quantity of its hot wind wind pressure is larger, at 13 upper end outlet of inner cavity Uniform upward thermal current is formd, when landing is carried out into inner cavity 13 high-water content steelmaking ingredient downwards, by reverse hot gas The influence of reaction force vertically upward is flowed, its falling speed is down to 300mm/s, and steelmaking ingredient is losing downward impact kinetic energy Afterwards, gently fall within inner cavity 13 and be laminated accumulation, percentage of damage can be controlled in 3%~5%.During continuous production operation, with every 6 it is small when Blowing output frequency once, carries out finished product output.Discharge port 21 described in the utility model expects for rotary discharge, can be with Effectively prevent the steelmaking ingredient in inner cavity 13 from producing whirlpool effect when discharging and expecting, effectively prevent dry and wet steelmaking ingredient mixing row The situation put.It is described rotation nest effect caused by ill effect be：When drying steelmaking ingredient, the refining of lower middle position in inner cavity Steel auxiliary material can form discharge central vortex in discharge so that the steelmaking ingredient quick drain at vortex, vortex side are complete Steelmaking ingredient into drying fails to enter and caves in discharge bumpy flow, cause the unfinished drying steelmaking ingredient on bumpy flow top with Discharge vortex is discharged.The utility model will not cause dry and wet steelmaking ingredient mixing row by rotatably discharging the uniform blowing of material energy Situation about putting.In addition, under the action of rotary discharge port 21, all steelmaking ingredients obtain turning over simultaneously conforming layer in inner cavity 13 Drop, can effectively improve drying efficiency.
Cylinder 1 in the present embodiment is installed on a stent 7, specifically as shown in Figure 1, stent 7 includes multiple legs, is passed through Leg supports cylinder 1, has certain distance between the discharge port 21 and ground, in order to discharge.
As shown in figure 3, the cylinder 1 in the utility model includes inner wall 14 and outer wall 15, shape between inner wall 14 and outer wall 15 Into the interlayer 11.Further, with reference to Fig. 3 and Fig. 4, multiple auxiliary connected with the inner cavity 13 are provided with the inner wall 14 Air port 141.By aiding in air port 141 to extrude, the steelmaking ingredient that will be close in inner wall 14 carries out auxiliary and follows hot wind in interlayer 11 Ring is dried, and further increases the heat exchange area of steelmaking ingredient and hot wind, with the first air port 41 and the second air port 52 to inner cavity 13 In steelmaking ingredient carry out comprehensive drying dehumidification.It is that aperture is 8mm~12mm that air port 141 is aided in described in the present embodiment Circular hole, the spacing in adjacent auxiliary air port 141 is 80mm~120mm.
As shown in figure 3, being respectively equipped with intermediate tube 8 on all vertical guide ducts 4, all intermediate tubes 8 are towards adjacent wind-guiding Position between plate 6.Intermediate tube 8 on different vertical guide ducts 4 can pass through convection current between two different wind deflectors 6 Both direction is carried out to steelmaking ingredient is evenly heated drying.
With reference to figure 2, in order to be effectively ensured the pressure in blast main 5 and air quantity, all transverse direction guide ducts 3 with blast main 5 It is connected.Further, all horizontal guide ducts 3 are uniformly distributed along the contour of blast main 5.
In conclusion a kind of steelmaking ingredient drying unit of the utility model, it is possible to increase production capacity, good working effect.So The utility model effectively overcomes some practical problems of the prior art so as to have very high utility value and using meaning.
The above embodiment is only illustrative of the principle and efficacy of the utility model, new not for this practicality is limited Type.The utility model also has many aspects to be improved on the premise of without prejudice to overall thought, for being familiar with this technology Personage all can under the spirit and scope without prejudice to the utility model, can to above-described embodiment carry out modifications and changes.Therefore, Such as those of ordinary skill in the art is in the revealed spirit without departing from the utility model and institute under technological thought All equivalent modifications completed or change, should be covered by the claim of the utility model.
