The technical scheme that realizes the utility model purpose is as follows:

The cold slag machine of a kind of many bench formula, comprise the urceolus that is installed on the frame, be placed in the inner core in the urceolus and be connected in the inner core inwall and be positioned at the outlet pipe at its center, in, cavity between the urceolus can be leaked water, the front end of urceolus is provided with into, delivery port, the lower end is provided with slag notch, the rear end is provided with slag inlet, outer drum outer wall middle part is installed with the gear ring that is connected with transmission device, before the outer drum outer wall, back segment is installed with rolling ring respectively, be installed with symmetric arrangement on the inner core inwall and with the throwing slag plate of its formation cavity be distributed in inwall and throw helical blade on the slag plate inwall, it is characterized in that, the described inner core that is placed in the urceolus is the staged setting, and each ladder is all by water inlet pipe connection water inlet independently.

Additional technical feature:

Described rolling ring is taken turns by the top that stopping means is installed on the frame.

Owing to adopted technique scheme, the beneficial effects of the utility model are: the cold slag machine of many bench formula adopts the double-deck water cold drum of a plurality of bench of gear driven, high temperature sludge enters the compound warehouse of cold slag machine by the water-cooled slag inlet, carrying out screw propulsion in many bench warehouse rolls, and the upset of process helical blade, shed, in many bench warehouse, can realize high flow rate, the repeatedly independent water-cooling circulating system of the big temperature difference, reduced warm sludge nest temperature, promoted water cycle heat exchange efficient, thereby improved the heat transfer efficiency between slag stream inside and the slag particle, reached the demand that adapts to and satisfy big bed drain purge of large-scale circulating fluid-bed and the tapping temperature that is fit to.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail.

As depicted in figs. 1 and 2, the cold slag machine of a kind of many bench formula, comprise the urceolus 3 that is installed on the frame 17, be placed in the inner core 4 in the urceolus and the outlet pipe 16 at inner core center, inner core 4 is divided into three sections, stepped distribution, cavity between the inside and outside tube can be leaked water, and its water system trend is: cavity → outlet pipe → delivery port that the inside and outside tube of water inlet → water inlet pipe → first ladder forms; Cavity → outlet pipe → delivery port that the inside and outside tube of water inlet → water inlet pipe → second ladder forms; Cavity → outlet pipe → delivery port that the inside and outside tube of water inlet → water inlet pipe → the 3rd ladder forms, its water inlet direction is opposite with the direction of slagging tap.Urceolus 3 outer middle side parts are installed with the gear ring 2 that is connected with gearbox 9, and gearbox 9 is driven by motor 8.Urceolus 3 outside front and rear sections are installed with rolling ring 1 respectively, and rolling ring 1 is taken turns on 7 by the top that stopping means 6 is installed on the frame 17, plays a supportive role; Be installed with symmetric arrangement on the inner core inwall and with the throwing slag plate 13 of its formation cavity be distributed in the inner core inwall and throw helical blade 14 on slag plate 13 inwalls, throwing slag plate 13 is to be the plate of spill and the similar oval cavity that the welding of inner core inwall forms by an inwall, and helical blade 14 is distributed on the spill inwall of throwing slag plate 13.Front end centre at inside and outside tube 3,4 is provided with entery and

delivery port
