Description

A kind of pre- heat drying mixing granulation furnace of wet mud

Technical field

The equipment that the utility model relates to a kind of in sludge handling process；Specifically a kind of pre- heat drying mixing of wet mud is made Grain furnace.

Background technique

The water content of sludge is very high, so needing to carry out drying and other treatment before sludge incineration, some are also needed in this rank Section mixing other materials, are more easier and sufficiently to burn.

Preheating method primarily now is disc dryer: wet mud is sent by feed inlet, in disk shell and hollow shaft Between flow, heat is transmitted by the hollow disc that welds on collet, hollow shaft and axis, material is heated indirectly desiccation, generates Water vapour be gathered in the dome of drying machine, drying machine is taken out of by cultivation gas；Hollow disc is completely vertical with axis, does not cut to material Play is mixed the effect of device by the propulsion of peripheral of disc/retouch, carries out propulsion stirring to material, dry face is constantly updated, to realize Dry purpose；The bearing part of whole drying machine, You Yigen hollow shaft and one group of hollow disk composition.

When work, what is be filled in this disc dryer is tens tons of sludge, stirs needs every time and consumes a large amount of electricity Can, conglomeration again is easy by the higher sludge of the humidity of pitch cutting, rear journey can only be continued to be heated to, when humidity is decreased obviously, It can accomplish not conglomeration.

Utility model content

The utility model is utilized again in view of the shortcomings of the prior art, providing and can generate hot powder ash to burning sludge, wet Mud is once granulated success, a kind of wet pre- heat drying mixing granulation furnace of mud of not conglomeration.

In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals: a kind of wet mud preheating First point of mud pan, the first ash-blowing tube, is distributed in the boiler in desiccation mixing granulation furnace, including a boiler from the top down One connects a basin, second point of mud pan, the second ash-blowing tube, second connects a basin and heating device, first point of mud pan and described second Connected by vertical connecting tube between point mud pan, first point of mud pan and second point of mud pan are in tube body towards bottom surface It is provided with several mudholes, first ash-blowing tube and second ash-blowing tube are in body pipe towards following and be provided with towards inner face Several ash output openings, and be connected with the hot powder ash pipe discharged during sludge incineration；Described first, which connects a basin and described second, connects Grain basin is provided with discharge port；

First point of mud pan is circumscribed with enters mud pipe and pushes away mud cylinder, and the described first discharge port for connecing a basin is arranged in boiler Outside；In the effect for pushing away mud cylinder, the extruded wet mud in part is in long strip from the mudhole of first point of mud pan to be squeezed Out, and in dropping process it is mixed with the heat ash sprayed from the ash output opening of the first ash-blowing tube, the institute for finally connecing a basin from first It states in discharge port and is discharged outside boiler, complete mixed once and preheat granulation process；

Remaining wet mud in first point of mud pan is entered in second point of mud pan by the connecting tube；

Wet mud a part of second point of mud pan passes through extrusion in long strip in mudhole under the action of gravity and extruding force, And mixed in dropping process with the heat ash sprayed from the ash output opening of the second ash-blowing tube, in the discharge port for finally connecing a basin from second It is discharged outside boiler, completes secondary mixing and preheat granulation process；

Remaining wet mud in second point of mud pan enters next procedure.

The tube body of the first point of mud pan and second point of mud pan indent vortex shape downward in center.

The outermost circle pipe welding of first point of mud pan and second point of mud pan has mounting ring, and the mounting ring passes through several It is supported and fixed on the inside of boiler.

Compared with prior art, the sludge quantity for having the following beneficial effects: that 1 promotes every time is small for the utility model, but number Ton, tens tonnes taken up than disc dryer turnover want energy saving many times；Also, present invention take advantage of that itself weight of wet mud Power is as sliding kinetic energy；2 the application carry out secondary use to the heat ash generated after burning, using its waste heat, and utilize its object Manage feature, hot ash particle is attached at wet mud surface so that the wet mud that squeezes out of strip will not conglomeration again, be conducive to burn；3 have Two procedures are rotated forward plus are inverted, and just carry out once rubbing mud, so that wet mud can be with stone in secondary mixing preheating granulation process The hard object separation of class；It may separate out the stone of the bulks such as stone, glass.
