Abstract
A vibration-type fluidized bed with wind cut-off discharge unit for eliminating the waste in airflow heat energy and fun power is composed of a main body with material inlet and outlet, and wind inlet and outlet, a vibration unit, and at least one layer of the perforated wind-distributing plate with discharge hole. Said perforated wind-distributing plate has a horizontal or inclined rectangular surface, or a circular ring surface, or a spiral surface.
Description
Technical field
The invention belongs to dry process equipment.
Background technology
Vibrated fluidized bed is to be widely used in the equipment that granular, the sheet in the products such as agricultural product and chemical industry, building materials and granular material are carried out dry processing.Under the effect of vibrating device, body is in vibrational state, the dry material for the treatment of on the wind distributing hole plate is realized fluidization, the air-flow (hot blast or cold wind) that enters in the body from bottom to top passes wind distributing hole plate and the dry material for the treatment of that is positioned on the wind distributing hole plate, carry out caloic transmission and exchange between air-flow and the material, make the water content for the treatment of dry material reduce, thereby realize treating the drying processing of dry material.When air-flow is hot blast, be drying machine, when air-flow is normal temperature wind, be cooler, all play desiccation.
Existing vibrated fluidized bed, comprising the loam cake ginseng shakes and without top cover vibration vibrated fluidized bed, no matter be individual layer wind distributing hole plate structure, or laminates wind AND DEWATERING FOR ORIFICE STRUCTURE, no matter be level or the rectangular surfaces wind distributing hole plate that is obliquely installed, or the wind distributing hole plate of anchor ring or helicoid, cause the waste of air-flow heat energy and power of fan in order to prevent material from when the blanking hole of the charging aperture of body and discharging opening and wind distributing hole plate falls, discharging air-flow, be provided with " blanking valve " at the charging aperture of body and the blanking hole place of discharging opening and wind distributing hole plate.But because this " blanking valve " belongs to " pressure gate-type " Bin-gate device, not power-actuated, bin gate is under the effect that is subjected to multiple power such as material gravity, stream pressure, spring force, vibration force, friction in pairs power, its open and close state can not be willing to ground adjusting automatically with the people, stops air-flow to be discharged when therefore can not accomplish to allow material to fall; Thus, the air-flow that causes entering vibrated fluidized bed is after passing material bed on bottom cloth wind orifice plate and the plate, part air quantity directly blows out body from discharging opening, another part air quantity is through the blanking hole of upper strata wind distributing hole plate, directly blow to exhaust outlet and discharge body, have only remaining part air quantity just to pass material bed on upper strata wind distributing hole plate and the wind distributing hole plate, to material generation desiccation; That is to say that above-mentioned preceding two parts air quantity does not all pass from material bed again, but has been discharged by " short circuit ", thereby has wasted air-flow heat energy and power of fan.
And on the other hand, strength carry with the dust removal by ventilation field in the airlock that uses and the vibra feeder that in fields such as mining, metallurgy, coal, is used for feeding all have the effect that stops the air-flow discharge when allowing material to fall, can satisfy fluid bed material is carried out that drying adds that its charging aperture in man-hour, discharging opening and blanking hole only allow the material whereabouts and the requirement that can not have air-flow to gang up.
Summary of the invention
The purpose of this invention is to provide a kind of vibrated fluidized bed that has unloading device of dynamical closed wind, in material being carried out dry process, its charging aperture, discharging opening and blanking hole can guarantee to close wind in blanking, air-flow " short circuit " does not promptly take place, thereby can make full use of air-flow heat energy and power of fan, improve drying efficiency.
The present invention is achieved in that it comprises body and the vibrating device that is provided with charging aperture, discharging opening, air inlet and exhaust outlet, and one deck is positioned at body and has the wind distributing hole plate of blanking hole at least, wherein, the wind distributing hole plate is rectangular surfaces and is level or is obliquely installed, or be anchor ring, or be helicoid, it is characterized in that said charging aperture and/or discharging opening and/or blanking hole are provided with the unloading device of dynamical closed wind that can stop air-flow to be ganged up when allowing material to fall.
Above-mentioned unloading device of dynamical closed wind is the airlock of charged motivation, wherein, the charging aperture of airlock or discharge port are communicated with the charging aperture of body and/or the charging aperture of airlock is communicated with the discharging opening of body and/or the charging aperture of airlock is communicated with the blanking hole of wind distributing hole plate and/or the charging aperture and the discharge port of airlock are communicated with the blanking hole and the body of wind distributing hole plate respectively.
Above-mentioned unloading device of dynamical closed wind is a vibra feeder, wherein, the mounting spring of vibra feeder is connected with body, and its hopper passes the cinclides of body and is positioned at charging aperture and/or the below of blanking hole, and vibra feeder is connected with body by the soft connector of being made by flexible material at the cinclides place.
The mounting spring of above-mentioned vibra feeder is connected with body, and hopper is positioned at the below of body discharging opening.
The above-mentioned wind distributing hole plate that is anchor ring is provided with the baffle plate of control material spilling direction and the stock guide that directing material flows to.
The present invention adopts the structure that unloading device of dynamical closed wind is set at the blanking hole of the charging aperture of body and/or discharging opening and/or wind distributing hole plate, in discharging, can guarantee to close wind, same material is carried out drying add man-hour, not only thermal energy consumption can reduce about 50%, and power of fan can reduce about 40%, occupation area of equipment can reduce about 30%, has simple in structure, energy-conservation and advantage efficiently.
