Problems solved by technology

In the process of sealing and transporting high-temperature materials in the traditional discharging machine, due to the uneven distribution of heat, it is easy to cause heat concentration, and the dynamic sealing function cannot be realized, causing the external pressure to be greater than the pressure of the pyrolysis furnace, resulting in positive pressure tempering, and escape The high-temperature pyrolysis gas may cause peripheral fires. Therefore, the conventional discharging machine has potential safety hazards and cannot meet actual needs.
In addition, it is easy to cause heat loss during operation, and there is a defect of low thermal efficiency

Embodiment 1

[0053] Such as Figure 1-4 As shown, a ball circulating screen dispensing powder seal isoniped, including a pyrolysis furnace rotary cylinder 1, and the thermofacco turning cylinder 1 and a pyrolytic furnace discharge end cover 2, powder sealing box 3, the ball circulation spiral hoist 4 and the drying furnace feed end cover 5 are sequentially connected; the thermofacco turning cylinder 1 includes a pyrolysis furnace rotary housing 1-1, a ball screening structure 1-2 is disposed in a pyrolysis In the furnace return housing 1-1, it is a pyrolysis of carbon powder and the separation of carbon powder and circulating ball. The thermofake rotary housing 1-1 is composed of a discharge stage and an effluent cone, and the outlet cone is connected to the ball sieve structure. The thermophilic furnace rotary cylinder 1 is provided with a ball screening structure 1-2, and the spherical screening structure 1-2 includes a ball screening fixing plate 1-2.1, the ball screening fixing plate 1-2.1 ...

Embodiment 2

[0059] The working principle of the balloon circulating sieve powder seal is:

[0060] (1) The organic material raw material is 50 mm or less by the fragmentation particle diameter, and the screw conveyor passes through the material feed port covering the feed end of the drying furnace, and the temperature of the remaining heat flue gas having a temperature of 200 ° C is directly heated to dry the material. The thermos gas temperature drops to 80 ° C, and is discharged by dry air outlet; the drying ball is completed under the rotation of the drying furnace, and the circulating ball is promoted to boost material movement in the drying section, assisting dry heat transfer .

[0061] (2) After drying the organic material with circulating balls, the feed is spirally entered into the pyrolysis furnace for indirect thermal solution. The high temperature thermal flue gas heating the thermofinder temperature is 600 ° C, and the pyrolysis carbonization temperature of the organic matter in ...

Abstract

The invention relates to a ball circulating screening and powder sealing discharging integrated device which comprises a pyrolyzing furnace rotary cylinder, and the pyrolyzing furnace rotary cylinder is sequentially connected with a pyrolyzing furnace discharging end cover, a powder sealing box, a ball circulating screw elevator and a drying furnace feeding end cover. A ball screening structure is arranged in the pyrolyzing furnace rotary cylinder and comprises a ball screening fixing plate, a ball screening net is arranged on the ball screening fixing plate, and a ball screening spiral structure is arranged in the length direction of the inner wall of the pyrolyzing furnace rotary cylinder. The side, close to the discharging end cover of the pyrolyzing furnace, of the ball screening spiral structure is connected with a ball pushing spiral structure, and circulating balls are arranged in the pyrolyzing furnace rotary shell. And the ball screening structure is utilized to ensure the separation of pyrolysis product high-temperature carbon powder and circulating balls, so that the phenomenon of adhesion of pyrolysis tar and coke is avoided, and the safety of equipment operation is further ensured. The powder sealing box is combined with the ball circulating screw elevator, so that the dynamic sealing performance of powder materials in the ball circulating conveying process is realized.

Description

Technical field [0001] The present invention relates to the field of discharge techniques of organic waste drying pyrolysis techniques, and more particularly to a ball circulating screen dispensing powder seal delivery integrated device. Background technique [0002] The information disclosed in the background is disclosed only to increase the understanding of the overall background of the present invention, and is not necessarily considered to admit or imply that the information is intended to be a prior art known to those skilled in the art. [0003] The drying process of the organic waste in the prior art is to put the material to be poured into the pyrolysis furnace for high temperature, and the thermal solution is discharged through the discharge mechanism, which is required for the entire pyrolysis process Isolated from the outside, so the discharge mechanism needs to be sealed. During the traditional air-sealing and transportation of high temperature materials, due to heat...
