This invention relates to an improved device for the disposition of solid materials.
More particularly it relates to a device for breaking up and disposing of furnace residues, distillation resldues and the like.
It has been customary in the disposition of solid residuesfrom a furnace to drop the same from the furnace hopper into a conduit through which the residues are conducted to a sump tank. The larger residues have been prevented from passing into the conduit from the furnace hopper by means of a grate and have been broken up manually r ,or otherwise separately disposed of.
- siderable valuable head room under hoppers and furnaces and is also economical in operation,'construction and maintenance.
Other objects will be apparent from the specification and from the accompanying drawings in which latter:
Fig. 1 is a longitudinal sectional view of the device;
Fig. 2 is a longitudinal section of a modification of the device, and showing associated parts. I
Referrin particularly to Fig. i 1 of the drawings, t e device comprises a receptacle 1 having an inlet hopper 2 adapted to receive incombustible residues from the discharge opening of a furnace bottom or hopper 3. A movable gate 4 controls the discharge of incombustible residues through the discharge opening. The receptacle can be. disposed upon the boiler house floor, as shown and so associated with the hopper as-to prevent escape of undesirable quantities of dust during the discrarge of the residues from the hopper. The end 5 ofthe'receptacle is provided with an-outlet 6 which communicates with a sluiceway or conduit 7. Liquid is adapted to be introduced into the sluiceway from nozzle 8 forming a conveyor. system whereby the'residues are conducted into sump tank 9. The portion of the receptacle beneath the inlet hopper 2 is provided with a line 10 removably disposed therein. The liner is preferably made of abrasion resisting metal and is sprung into positive engagement with the walls of the receptacle. A second liner 11 of similar material is detachably secured in the receptacle, one end thereof abutting the liner 10 and the opposite end abutting the end wall 5 of the receptacle.
1 Cutting means are disposed upon a shaft 12 which is mounted within the receptacle and is adapted to be rotated by a source of power (not shown). The cutting means comprises a plurality of collars 13 which are rigidly affixed to the shaft. Each collar carries a plurality of teeth 14 extending therefrom at an angle to the length of the collar and each tooth is semi-spirally shaped from its base to its tip, also the edges of the teeth are bevelled to increase their cutting ability. The edges of the teeth terminate in spaced relation to the ends of their respective collars.
Liner 10 is equipped with a series of teeth (11a) on one or both sides attached at an elevation of approximatel the center line of the shaft and so spaced that the shaft teeth pass between them.
A helix is formed upon the shaft 12 within the liner 11 and is adapted to cooperate therewith to move the broken incombustible residues toward the discharge opening. The helix is formed b a plurality of collars 17 rigidly aflixed to t e shaft, each collar carrying a section 18 of a helix. When assembled with the helix sections in abutting relation the sections form a complete helix.
The broken incombustible residues are fed forwardly by the helix into the space between the end of the helix and the end wall 5 and are compacted in this space. Successive increments of the compacted residues are fed through the outlet 6 by means of a plurality of teeth-2O carried by. a collar. 21 which is ri idly ailixed to the shaft 12.
l n the operation of the device the incombustible residues are dropped through the inlet hopper 2 into the receptacle. The drive shaft 12 is rotated in a clockwise direction as viewed from end 5 causing the rotating teeth 14 operating in connection with stationary teeth 11a to chip the residues into small pieces and at the same time, by virtue of the inclination of the teeth to effect a lateral movement of the pieces toward the helix. The broken pieces are conducted by the helix toward the end wall 5 and are fed by the teeth 20- through the outlet 6 into sluiceway 7 through which they are washed by'liquid from nozzle 8 into the sump tank 9. 1
In the embodiment illustrated in Fig. 2a furnace 23 is mounted immediately above the boiler house floor 24. Residues are dropped from the hopper onto inclined feed plates 25 from which they are flushed by means of liquid from nozzles 25a through a grate 26 into a conduit 27 which is disposed beneath the boiler house floor. Liquid from a nozzle 28 flushes the residues through the'conduit 27 into a sump tank 30 which can be dis osed exteriorly o the boiler house. A 'scharge pipe 31 is provided to remove overflow water from the sump tank. A grinding device is disposed in the bottom of the sump tank and comprises a shaft 33 which is driven in rotation from the pulley wheel 34. A thrust bearing 35 prevents endwise thrust of the shaft. A plurality of collars 36 are dis osed rigidly upon the shaft in abutting re ation and carry grinding teeth 37 thereon. These rotating grinding teeth 0 crating in conjunction with stationa teet 37a serve to break up the residues arid move them laterally toward the right asviewed in Fig. 2 as has previously been described. A helix 38 re-,
ceiv'es the broken ash and moves the same laterally into the space 39 between the end of the casing 40 and the end of the helix. Blades 41 disposed upon the shaft 33 tend to force the residues through opening 42 into a atSjlmp tank 43. Liquid such as water can be introduced into the upper portion of space I 39 through a pipe 44 to wash the residues into tank 43. The mixture of residues and water can be pumped by pump 45 through ipe 46 into stora e tank 47 A discharge con uit 48 is adapt to withdraw the water from the residues in tank 47 to sum tank 30.
While particular embo cuts of the invention have been shown and desci ibed it will be understood that modifications can be made therein or other modifications made without departing from the spirit of the invention and it is not desired to limit the scope of the invention otherwise than is indicated by the accom anyng claims.
I at I claim is: V

An apparatus for 'handlingashes from a fuel burning furnace comprising a. receptacle adapted to reoeive 'such ashes, an andisp nular extension cdmmumcating with the re- ,ing, rotatab which the spaced means on the shaft in the receptacle are spirally shaped sharp edged teet 3. The apparatus set forth in claim 1 in which the means on the shaft in the extension is a spiral conveyor.
