Abstract
The utility model relates to a kind of screw conveyors, the solid materials such as ash, slag for output in rotary kiln, the solid materials such as ash, slag are cooled down, cigarette, gas, the dirt for being sealed, rotary kiln inner outlet being isolated are squeezed using material accumulation, and outside air is prevented to enter a kind of conveying equipment in rotary kiln.The utility model is to rotate pusher by lower part helical blade to accumulate to form circular ring shape material sealing and be sealed at on-bladed optical axis, and gas inside and outside kiln is isolated.
Description
Technical field
The utility model belongs to solid waste processing transmission equipment technical field, more particularly to a kind of helical feed
Machine.
Background technique
High, the furnace gas generally nocuousness in the ash of domestic garbage resource third generation rotary kiln product output, slag temperature
Composition, and be continuous output state.Existing slag cooler out has unloading valve to add lag cooler, and double flap valves add lag cooler or double-gate
(slotting) plate valve adds lag cooler.Because output object temperature is high, the sealing of above-mentioned all valves can only take metal sealing, and output object also can be right
Valve generates phenomena such as abrasion, card, and all valve prior arts are substantially to pass through the switching of mechanical action: the first valve
Open-material fall the-the first valve close the-the second valve open-material drops down onto the cooling output object output of lag cooler-lag cooler.It is existing
Some methods are at high cost and sealing effect is bad, and because output object temperature is high, the sealing of above-mentioned all valves can only take metal close
Phenomena such as envelope, output object can also generate abrasion, card to valve, and valve cycles having time is poor, inevitably there is partial compromise.Its is close
It is bad to seal effect.
Our company develops first generation screw conveyor, a kind of spiral heat exchange conveying of Patent No. CN201721206406-
The utility model patent of machine and screw conveyor shaft, as closest to documents.Documents utility model patent solve because
Output object temperature is high, and the sealing of all valves can only take the technical solution of metal sealing.Documents are connected with hot friendship using hollow
The hollow tube for changing medium (water), the cored screw blade being connected on axis, helical blade separate out material mouth about twice screw pitch
Seal clearance, and device is installed by the way of being inverted 60 degree of inclination, i.e., discharge port is higher than feed inlet, discharge port and spiral
Gap between blade is full of filler, uses convolution kiln and external hermetic seal.But there are spiral heat exchange to convey for the utility model
When machine enters big material and foreign matter, there is card machine situation and be unfavorable for filler cleaning, it again can not be card machine from discharge port
Spiral exchange heat conveyer in filler cleaning, even if spiral exchange heat conveyer reverse starting, because filler be arranged in spiral
The seal clearance of blade upper end and discharge port, discharge port be higher than feed inlet so that filler always fixing seal gap area without

Specific embodiment
It should be noted that in the absence of conflict, the feature in the embodiments of the present invention and embodiment can
To be combined with each other.The utility model will be described in detail below with reference to the accompanying drawings and embodiments.
The utility model is to rotate pusher by lower part helical blade to accumulate to form circular ring shape material envelope at on-bladed optical axis
Layer is sealed, and gas inside and outside kiln is isolated.A kind of screw conveyor of the utility model, specifically comprises the following steps:
8 output shaft of decelerating motor is rotated with torque limit shaft coupling 7 and Shaftless spiral blade 4, when kiln in-furnace dust, slag fall
It is intracavitary to fall within screw conveyor U-shaped, shaftless rotating vane 4 send material to toroidal cavity at on-bladed, behind continuous supplied materials,
Material material extrusion is gradually accumulated to form the closely knit circular ring shape bed of material, to form sealant 100.If continued blanking in kiln, pass through material
The mode of material extrusion is by on-bladed section, then transports material to discharge port 24 by shaftless rotating vane 4 and discharge.As kiln mouth does not have
Blanking, the material of sealant 100 then original place will not by it is defeated walk.The effect of windrow taper liner 5 is to increase resistance, does not allow the object of bottom
Material easily it is defeated walk, so as to the bed of material accumulation.The effect of elastic slice 13 is to allow generate precompression, so that feed inlet 26 is come in without material
Into Shaftless spiral blade 4 keeps annular seal layer top when rotation not collapse.Second resistance rotation level detector 92 is as a long time
(such as one hour or more) does not detect supplied materials, issues signal control decelerating motor 8 and stops operating, when the first resistance rotation material position
Device 91 is detected with material, issues signal control decelerating motor 8 and restores rotation.When product material is excessive in kiln, no leaf is caused
It is squeezed too tight at piece so that torque is excessive, torque limit shaft coupling 7, which just disengages protection equipment and issues signal system decelerating motor 8, to stop
Rotation stop is dynamic.Here pulp cutlet 3 to be opened, decelerating motor 8 inverts, and partial material exports from pulp cutlet 3, then pulp cutlet 3 is shut,
Decelerating motor 8 rotates forward to continue to convey material, and pulp cutlet can also be made to automatically control.
In conclusion the utility model has the advantages that
Spent material self-sealing is better than using valve seal effect at high operating temperatures, and it is close to solve previous generation screw conveyer
Packing charge cannot be discharged, and further solve the problems, such as card machine, reliable performance；Torque limit shaft coupling mechanical restriction moment of torsion is than electricity
Ductility limit way of torque is swift in response, and is conducive to protect equipment.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
