Abstract
The invention relates to a vibration feeding device applied in a deposition fluidized bed. The vibration feeding device comprises a feeding barrel and an actuating part. The feeding barrel stores bed layer particles for the deposition fluidized bed. The actuating part can touch the feeding barrel periodically so that the feeding barrel generates vibration under touch, thus achieving discharge of the bed layer particles. The novel vibration feeding device applied in the deposition fluidized bed can effectively solve disadvantages of gas-carrying type feeding devices in the prior art, and can achieve a stable and controllable feeding amount. When the vibration feeding device is applied in the deposition fluidized bed, a stable-state deposition reaction process can be achieved.

The specific embodiment
System in the present invention utilizes chemical vapor deposition method to prepare isotropic pyrolytic carbon material.Fig. 2 is system diagram, is mainly divided into reaction unit, feed arrangement, drawing mechanism, sensing and control device, thermatron five parts.In reaction unit, high frequency induction power supply heats precipitation equipment by induction coil, with photoelectric pyrometer, temperature control system, measures and regulation and control depositing temperature.Precipitation equipment is graphite conical fluidized bed precipitation equipment.Dilution and carrier band gas are hydrogen, argon gas or nitrogen etc., and the flow of gas is measured and controlled by flowmeter and needle-valve.The tail gas that reaction produces is processed by exhaust treatment system.As shown in Figure 1.The reaction zone of precipitation equipment is provided with back taper opening, realizes bed particle fluidization.Hydrocarbon gas and carrier gas pass into from gas access and blow diameter is that bed particle forms fluidization in reactor.In deposition process, by the drawing mechanism of precipitation equipment bottom and the feed arrangement on top, realize the stable replacing of bed particle, can be continuous by feed arrangement and drawing mechanism to adding in fluid bed or emitting bed particle.
The reaction zone of precipitation equipment is provided with back taper opening, realizes bed particle fluidization.Hydrocarbon gas and carrier gas pass into from gas access and blow diameter is that the bed particle of 0.2mm-0.5mm forms fluidization in reactor.In deposition process, by the drawing mechanism of precipitation equipment bottom and the feed arrangement on top, realize the stable replacing of bed particle, can be continuous by feed arrangement and drawing mechanism to adding in fluid bed or emitting bed particle.
As shown in Figure 3-Figure 5, feed arrangement has feeding cylinder, eccentric rotary parts and the drive motors that holds bed particle, motor drives eccentric rotary parts to rotate, property performance period touching feeding cylinder, and make the displacement of feeding cylinder generating period lateral vibration, and feeding cylinder bottom is back taper, and feeding cylinder is connected by screw in feed arrangement fixed mount, in its underpart, adopt spring to support, can make it carry out vibration displacement, below, feeding cylinder inside is provided with charging orifice plate, on charging orifice plate, there are one or more charging holes, the 1-5 of the general optional bed particle diameter of charging hole diameter doubly, under normal circumstances, the bed particle holding in feeding cylinder is each other due to friction and Extrusion effect, can not pass through smoothly charging hole, when eccentric rotary parts are periodically touched feeding cylinder, the bed particle holding in feeding cylinder is under vibration force effect, friction and Extrusion effect weakens each other, the bed particle of some can pass through charging hole smoothly, after the rotation of eccentric rotary parts is passed through, because vibration force effect disappears, the bed particle holding in feeding cylinder can recover inactive state again under friction and Extrusion effect, cannot pass through charging hole.By selecting charging hole quantity, diameter dimension and controlling motor rotary speed, can achieve effective control feed particles amount.In addition, motor can adopt forward and reverse rotation mode work, reduces rotating mechanism and takes up room and increase work efficiency.
Feed particles amount is controlled motor direction of rotation and the rotational speed regulation of feed arrangement by sensing and control device, the charging frequency of feed arrangement is regulated to the technological parameters such as real-time maintenance bed area, fluidized state stable.The above-mentioned cycle actuating mechanism of realizing based on motor, also can adopt other conventional similar periodicity actuating mechanism, as electric and magnetic oscillation, and air pressure or hydraulic vibration.
By above feed arrangement, realized the accurate and effective of bed pellet feed amount and controlled.
