Description

Vibrative kiln

The utility model relates to the stove apparatus field, particularly relates to a kind of kiln that has vibrating device.

The roasting, calcining, the modal kiln with dynamic function of kiln expanded, retort process that are used for material at present are rotary kiln, it be under the slightly-inclined state by the revolution and gravity make material by height to harmonic motion.Because the kiln body needs unitary rotation, power consumption is big.The heat that distributes in the kiln can not reclaim, and heat loss is bigger, and rotary kiln can only be lighted a fire from kilneye in addition, and it is inhomogeneous, insufficient to burn, and supplies consumption is bigger.

The purpose of this utility model is the deficiency that overcomes existing rotary kiln, and the Vibrative kiln that a kind of power consumption is little, burn evenly, can reduce the loss of kiln body heat is provided.

The technical solution of the utility model is such.According to different needs, Vibrative kiln can have preheating, decomposes, burns till, the coking Vibrative kiln; The cooling Vibrative kiln; Expanded destructive distillation Vibrative kiln.Preheating, decompose, burn till, the coking Vibrative kiln comprises on the arch pad kiln body under the fender kiln body and flute profile, last fender kiln body is made up of refractory concrete inwall and heat-insulation layer, following pad kiln body is made up of water-cooled inwall and heat-insulation layer.Cooling is made of box kiln wall with the Vibrative kiln body.Expanded destructive distillation has been removed the water-cooled inwall with pad kiln body under the Vibrative kiln, and for the steel plate wall of refractory lining is housed, the vibrating body in the pad kiln body is the box vibrating body.The corresponding site of three kinds of kiln bodies is provided with the elastic supporting mechanism that comprises structural member, cross bar and spring and comprises the vibrating mechanism of eccentric wheel, belt gear and motor.Vibrating body in the pad kiln is supported by structural member, and cross bar stretches out pad kiln down, and the both sides of cross bar are connected with the helical spring of respective angles, are fixed on ground or the steel frame by damping devices such as ballast aggregate or slam-shots by horizontal pillow again.The vibrating body end liner places on the structural member, and is connected with camshaft by the supporting connecting rod.Eccentric wheel is arranged on the center line of kiln body middle part, is driven by belt transmission by motor.The certain angle of vibrating body bottom surface inclination.

The utility model has following advantage:

1, owing to elastic supporting mechanism of the present utility model and vibrating mechanism effect, material can be realized unobstructed, sufficient thermal response in the vibrating body that is tilting under vibration force and the gravity effect.

2, the utility model can replace rotary kiln, shaft kiln cement baking, conducts heat up and down in its preheating zone, but clinkering zone multiple spot cloth fire, and salband can be fully air-cooled.In like manner, this burns till Vibrative kiln and can be used for firing materials such as aluminium oxide, pitch coke, pellet.

3, low temperature distillation operation such as expanding food operation and coal wood chip adopts expanded destructive distillation of the present utility model Vibrative kiln, and technological effect is better than existing device.

4, the utility model can be used as low temperature distillation in the coal, and the Vibrative kiln of the box vibrating body of heat-resistance stainless steel material is arranged in the employing, and recyclable most fugitive constituents reduce production costs, and technology is simple.Increase coking again and cool off Vibrative kiln and be three sections Vibrative kiln coal-coking processes.

5, except that above-mentioned Vibrative kiln cement baking and coking, between the dissimilar Vibrative kilns and and some existing kilns between various combination can form various new thermal response mode and equipment, as: Vibrative kiln and low-shaft blast furnace combination ironmaking, Vibrative kiln and tank furnace combination melting glass, Vibrative kiln shape water-tube boiler etc.

Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.

As Fig. 1, Fig. 4 and shown in Figure 5, preheating, decompose, burn till, the coking Vibrative kiln comprises on the arch pad kiln body under the pad kiln body and flute profile, last pad kiln body is made up of refractory concrete inwall (4) and heat-insulation layer (1), air-cooled steel pipe (3) can be housed in the inwall (4), between inwall (4) and the heat-insulation layer (1) one deck steel plate shell (2) be arranged.Following pad kiln body is made up of water-cooled inwall (6) and heat-insulation layer (5).The vibrating body that can fill material (15) is arranged in the kiln body, and (8) are the vibrating body steel sole plate.Be provided with elastic supporting mechanism and vibrating mechanism at kiln body corresponding site, elastic supporting mechanism comprises structural member (9), cross bar (10) and diagonal brace helical spring (14).Vibrating body is supported by structural member (9), when operating temperature is very high, adopt the water-cooled steel pipe to do structural member, the cross bar (10) that is connected with structural member (9) stretches out pad kiln body down, between the two by sealing weakenings such as asbestos rings, be connected with the helical spring (14) of respective angles under the cross bar (10), also can increase a little leaf springs (26).The lower end of spring (14) connects horizontal pillow (11), is fixed on ground or the steel frame (12) by ballast aggregate and slam-shot damping device (13) again.Vibration drives by being installed in the outer vibrating mechanism of pad kiln, vibrating mechanism comprises eccentric wheel (23), belt gear (24) and motor (25), the vibrating body end liner is connected with camshaft (22) by supporting linkage (20), and the flywheel (21) of balanced action has been housed on the axle (22).As can be seen from Figure 5, the certain angle of vibrating body end liner inclination.End liner (7) is provided with and can makes the sufficient streamlined projection of material thermal response body (27), and (28) are the formula burner burner of getting angry.

As shown in Figure 2, cooling is made of box kiln wall (16) with the Vibrative kiln body.Because the salband part, hot blast temperature can improve and not have kiln circle burning problems, can be double-deck air-cooled, and in the space that the kiln body steel plate in high temperate zone constitutes, arrange one section water-cooled, and make cooling velocity fast, UTILIZATION OF VESIDUAL HEAT IN is effective.Outside salband, do not establish the pad kiln.The same preheating of its vibrating mechanism and elastic supporting mechanism, decompose, burn till, the coking Vibrative kiln.

As shown in Figure 3, expanded destructive distillation is the steel plate wall that refractory lining is arranged with the following pad kiln (18) of Vibrative kiln, box vibrating body (17) is arranged in the kiln body, and the box vibrating body (17) in the pad kiln adopts heat-resistance stainless steel material or ferrous materials, and kiln body bottom is provided with burner (19).
