Abstract

The utility model relates to a drying device, in particular to a domestic garbage continuous feeding and drying device, which comprises a shaftless screw conveyor and a rotary drying kiln, wherein the shaftless screw conveyor mainly comprises a feed hopper, a motor, a bunker body and a shaftless helical blade in the bunker body; the feed hopper is arranged at the upper end of the bunker body; the shaftless helical blade is connected to a rotating shaft of the motor and is arranged in the bunker body; a discharge opening of the shaftless screw conveyor is connected with a feed opening of the rotary drying kiln; a kiln head, a cylinder body and a kiln tail are sequentially arranged from the feed opening of the rotary drying kiln; the transmission device is arranged below the cylinder body; kick-out spiral masonry is circumferentially arranged on the inner wall of the cylinder body; and a high-temperature flue gas outlet pipe is arranged at the front end of the cylinder body. By adopting the domestic garbage continuous feeding and drying device, the problems of discontinuous and uneven feeding and nonflammable garbage due to high water content in garbage during the garbage feeding process are solved, therefore the domestic garbage continuous feeding and drying device can be extensively applied to the pre-drying treatment and feeding before burning of the domestic garbage with high water content and low heating value.

Description

A kind of house refuse continuous feed drying unit
Technical field
The utility model relates to a kind of drying unit, refers in particular to a kind of house refuse continuous feed drying unit, and it is applicable to prebake processing and charging before the consumer waste incineration.
Background technology
In waste incineration, garbage feeding high-moisture percentage discontinuous and rubbish (particularly domestic waste) influences the firing efficiency and the effect of rubbish, is common problem.Waste incineration feed arrangement in the past mainly adopts the hydraulic pressure push feed system, and its weak point is: 1, charging is discontinuous, influences the rotary kiln drying efficiency, makes that the interior waste incineration operating mode of incinerator is not enough; 2, to cause turning round drying kiln outlet blanking inhomogeneous because of interrupted charging, and quality and output are burned in influence.It all is to finish in incinerator that general rubbish oven dry is burned, when msw water content Gao Shiyin drying effect difference is difficult to burn.
The utility model content
The purpose of this utility model provides a kind of house refuse continuous feed drying unit, its part high-temperature flue gas that self produces when realizing that evenly charging utilizes waste incineration simultaneously continuously carries out high efficiency drying to rubbish, to solve the problem that garbage feeding high-moisture percentage inhomogeneous and rubbish (particularly domestic waste) influences the firing efficiency of rubbish and burns quality and output.
For realizing the purpose of this utility model, the inventor takes following technical scheme: a kind of house refuse continuous feed drying unit, comprise Shaftless screw conveyor and revolution drying kiln, wherein Shaftless screw conveyor is mainly by feed hopper, motor, warehouse, Shaftless spiral blade in the warehouse constitutes, feed hopper is arranged on the upper end of warehouse, Shaftless spiral blade is connected on the machine shaft and in warehouse, the Shaftless screw conveyor discharging opening is connected with revolution drying kiln charging aperture, the revolution drying kiln is followed successively by kiln hood from its charging aperture beginning, cylindrical shell and kiln tail, transmission device is arranged on the below of cylindrical shell, cylinder inboard wall is circumferentially with material toggling spiral masonry, and the front end of cylindrical shell is provided with the high-temperature flue gas outlet.
House refuse continuous feed drying unit of the present utility model can effectively solve the high problem such as nonflammable of interrupted, the inhomogeneous and msw water content of the charging that occurs in the garbage feeding process, guaranteed rubbish evenly, continuous feed and high efficiency drying burn, and can be widely used in prebake processing and charging before the low consumer waste incineration of moisture content height, calorific value.
Description of drawings
Fig. 1 is a broken section structural representation of the present utility model.
The specific embodiment
Now describe the utility model embodiment in detail: a kind of house refuse continuous feed drying unit in conjunction with Figure of description, as shown in the figure, comprise Shaftless screw conveyor 100 and revolution drying kiln 101, wherein Shaftless screw conveyor is mainly by feed hopper 1, motor 2, warehouse 3, Shaftless spiral blade 4 in the warehouse constitutes, Shaftless screw conveyor feed hopper 1 is arranged on the upper end of warehouse 3, Shaftless spiral blade 4 is connected in motor 2 rotating shafts and in warehouse 3, the Shaftless screw conveyor discharging opening adopts bolt to be connected with revolution drying kiln charging aperture, the revolution drying kiln is followed successively by kiln hood 6 from its charging aperture beginning, cylindrical shell 7 and kiln tail 10, air inlet 13 is arranged on kiln tail 10, transmission device 9 is arranged on the below of cylindrical shell 7, cylindrical shell 7 inwalls are circumferentially with material toggling spiral masonry 8, the front end of cylindrical shell 7 is provided with high-temperature flue gas outlet 5, and cylindrical shell 7 two ends also are provided with sealing device 11 and are used to prevent that the gas in the rotary kiln from overflowing.During work, Shaftless spiral blade 4 is under the drive of motor 2, rubbish is involved in and is fed forward, make garbage energy evenly enter the revolution drying kiln continuously, in the revolution drying kiln, when the front end of rubbish from cylindrical shell 7 enters, transmission device 9 drives and drives cylindrical shell by gear 12 transmissions and rotates, rubbish is moved to kiln tail 10 lentamente, the high-temperature flue gas that comes out from incinerator enters the revolution drying kiln from air inlet 13 high temperature of kiln tail 10, rubbish is under the effect of material toggling spiral masonry 8, in cylindrical shell 7 rotary courses,, fall to rolling by self gravitation then, in this process, fully contact with high-temperature flue gas along the kiln wall certain height of climbing, carry out countercurrent heat exchange, with rubbish heating and take away moisture.Rubbish after the prebake is discharged by kiln tail 10, falls in the incinerator.Oven dry back mixed flue gas is discharged from high-temperature flue gas outlet 5, enters after treatment again and does the combustion air use in the incinerator.Because Shaftless screw conveyor is used in combination with the revolution drying kiln, thus make rubbish can be evenly, continuous feed, and make rubbish carry out sufficient heat exchange with high-temperature flue gas, the rubbish of the stable and drying for the treatment of capacity is provided for follow-up burning disposal.
