The specific embodiment
Fig. 4 is the direction of overlooking of the present utility model.
As shown in Fig. 4 to Fig. 9, high intensity electric arc stove feed hopper of the present utility model comprises cylindrical shape upper shell 1, upper shell 1 is connected with taper type lower shell 2 downwards, lower shell 2 lower ending openings are as hopper discharging opening 3, upper shell 1 upper end open is as hopper feed mouth 4, and upper shell 1 and lower shell 2 form the cylindrical shell of hopper.
As shown in Fig. 4 to Fig. 9, upper shell 1 upper end level is provided with cross backstay group 5, and upper shell 1 lower horizontal is provided with cross bracing piece group 6; Upper shell 1 axis place is provided with valve rod 7, valve rod 7 is through described backstay group 5 and bracing piece group 6, valve rod 7 tops protrude upward hopper feed mouth 4, valve rod 7 bottoms are stretched out hopper discharging opening 3 downwards and are connected with most advanced and sophisticated cone 8 upward, cone 8 bottom surface diameters are greater than hopper discharging opening 3 diameters, and cone 8 and valve rod 7 form outlet valve; As shown in Figure 5 and Figure 6, described cone 8 sides are provided with rubber application of anti-leakage layers 9, and the bottom 21 of described taper type lower shell 2 is the ring-type frustum face suitable with described rubber application of anti-leakage layers 9; Valve rod 7 in described hopper cylindrical shell is provided with two above rod for stiring materials 10, and each rod for stiring materials 10 is along valve rod 7 between the upper and lower every setting, preferably along described valve rod 7 between the upper and lower every 4 rod for stiring materials 10 are set.
As shown in Figure 5 and Figure 6, described cone 8 can be both hollow cone, can be also filled circles cone.
As shown in Fig. 5 and Fig. 7, described lower shell 2 outer surfaces are fixedly connected with vibrating motor 11.Described upper shell 1 is interval with the horizontally disposed cannelure 12 of twice up and down, and the interior tight fit respectively of twice cannelure 12 is provided with rubber slab 13, and the outward flange of rubber slab 13 protrudes cannelure 12 and is square.
As shown in Fig. 4 to Fig. 9, described valve rod 7 tops are provided with suspension ring 14, thereby both the suspension hook of suspender easy to use hooked the suspension ring 14 high intensity electric arc stove feed hopper of the present utility model of slinging, and convenient operation personnel grip suspension ring 14 with hand and operate again.
The surface of described rubber slab 13 is provided with corrugated or latticed anti-slip veins (not shown), and anti-slip veins also can be set to other tiny anti-skidding lines such as decorative pattern shape certainly.
As shown in Fig. 4 to Fig. 9, described valve rod 7 welded top have horizontally disposed shaft-like handle 15.While there is material accumulation phenomena in hopper, the two ends that operating personnel can grasp shaft-like handle 15 rotate shaft-like handle 15 or up and down reciprocatingly twitch, thereby drive each rod for stiring materials 10 to rotate in hopper cylindrical shell or move up and down, by the material scattering gathering, material can be swimmingly discharged from discharging opening 3.
The surface contacting with discharging opening 3 due to described cone 8 is inclined plane, therefore open after valve, material can be at the surface sediment of cone 8, and can flow downward along cone 8 sides, so just avoided using in the past solid accumulation that the horizontal valve plate 57 shown in Fig. 1 brings on valve plate, the incomplete phenomenon of discharging.
When bulk transport or storage the utility model, as shown in Figure 8, the contact site of adjacent arc stove feed hopper is the side of rubber slab 13.Because rubber slab 13 outlines (being the outward flange of described rubber slab) are square, thus each electric arc furnaces feed hopper can be easily neat, be closely aligned together, be highly susceptible to arranging.Contact site due to adjacent arc stove feed hopper is the side of rubber slab 13 in addition, therefore the mode of comparing hopper cylindrical shell (existing hopper cylindrical shell is all metal cylinder) line contact has in the past strengthened frictional force greatly, when transporting or depositing, between electric arc furnaces feed hopper, be difficult for, because of the effect of external force, mutual displacement occurs.While there is generating collision in transit, rubber slab 13 sides that are in contact with one another are stressed place.The stressed line place being in the past in contact with one another of comparing, side is concentrated stressed, puts suffered pressure less at stressed identical situation lower stress; Add the intrinsic cushioning effect of rubber slab 13, the cylindrical shell of electric arc furnaces feed hopper can access good protection in transit, can not deform, damage.
Before using the utility model charging and feeding in raw material to electric arc furnaces, rubber slab 13 can be taken off from upper shell 1.
When filling with substance, hopper cylindrical shell relies on self gravitation to be pressed in the rubber application of anti-leakage layers 9 of described cone 8 surface settings.Because rubber has elasticity, thus hopper cylindrical shell press after its lower end can fall into into rubber application of anti-leakage layers 9, thereby realize good sealing effectiveness, avoid feeding in raw material, the phenomenon of material from leakage during storing in the past.
When reinforced to electric arc furnaces, use suspender to hook suspension ring 14, by high intensity electric arc stove feed hopper of the present utility model handling to electric arc furnaces charge door top, use the supporter supports barrel outer surface of staying, then make suspender no longer to suspension ring 14, apply the upwards power of lifting, now, under the effect of material gravity, described cone 8 pressurizeds move down, thereby realize, open valve events, material flows out and falls into electric arc furnaces along discharging opening 3.
If there is material accumulation phenomena when reinforced, can Vibration on Start-up motor 11, can also rotate shaft-like handle 15 by hand or up and down reciprocatingly twitch bar handle 15.At effect of vibration, rod for stiring materials 10 rotation material toggling effects and rod for stiring materials 10, up and down reciprocatingly stir under the effect of material, the material that gathers in cylindrical shell is spread out, and realizes discharging swimmingly.
In a word, high intensity electric arc stove feed hopper of the present utility model is compared in tube structure in the past cost-saving in strengthening, is storing or is being convenient to marshalling during transportation, and can prevent that hopper cylindrical shell is out of shape, damages because of carriage oscillating.The utility model can also be avoided the phenomenon that discharging is in the past incomplete and the front material appearance of discharging is leaked, and can break up again material, makes the smooth and easy outflow of material when material gathers.
Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only, although the utility model is had been described in detail with reference to above-described embodiment, those of ordinary skill in the art is to be understood that: still can modify or be equal to replacement the utility model, and not departing from any modification or partial replacement of spirit and scope of the present utility model, it all should be encompassed in the middle of claim scope of the present utility model.
