The specific embodiment
As shown in Figure 1, 2, 3, dry slag-draining device comprises boiler transition slag bucket 1, steel band slag extractor 13, between boiler transition slag bucket and steel band slag extractor hearth deslagging device 5 is installed; Boiler transition slag bucket 1 is mainly used in the storage slag, and connects boiler and hearth deslagging device 5, boiler transition slag bucket 1 independent support, and inner lining refractory and insulation material, its capacity is determined MCR8 according to boiler slag removal amount size design.Big slag disintegrating machine 2 is arranged in the porch of hearth deslagging device 5, and what present embodiment adopted is the opposite opened hydraulic breaker, can carry out precrushing to big clinker; The opposite opened hydraulic breaker is equipped with organizes independently extrusion head 4 more, and extrusion head 4 is connected by the outer driving hydraulic cylinder 8 of link rod 6 and casing, drives hydraulic cylinder and is installed on the outer support 9 of casing.Grid 3 is installed in the below of big slag disintegrating machine 2, is made up of the passive I-steel 11 of high temperature resistant steel pipe 10 and its underpart, and is connected on the casing.Grid 3 can be protected steel band 16, and big slag can not directly be dropped on the steel band 16 of steel band slag extractor; Big slag disintegrating machine 2 and grid 3 pass through case supports; There is expansion joint 7 on casing top and is connected with 1 sealing of boiler transition slag bucket, and lower box links to each other with the top sealing of steel band slag extractor 13.Extrusion head 4 bottoms of opposite opened hydraulic breaker are equipped with running roller 12, and this running roller rolls on the high temperature resistant steel pipe 10 of grid, and the change sliding friction is rolling friction, has reduced frictional force, make extrusion head 4 on grid 3 back and forth freely, improved operating efficiency.Drive hydraulic cylinder 8 and be located at the casing outside, be not subjected to the baking of 800 ℃ of temperature in the boiler transition slag bucket, oil cylinder can be worked under 30 ℃～50 ℃ nominal situations, and the dismounting of this structure, be convenient to maintenance.Be provided with observation window 14 and camera in the both sides of hearth deslagging device 5, also can observe the slag situation by shooting and monitoring system, the extrusion head that starts the relevant position carries out independent fragmentation, saves energy, increases work efficiency.
Shown in Fig. 4,5,6, it is tooth-shape structure that the extrusion head 4 of opposite opened hydraulic breaker is split an end, and extrusion head is conical surface body along the direction of motion, can reduce contact area, increases pressure, is convenient to the clinker fragmentation; Riser 15 is installed on the extrusion head,, can cuts off big clinker by riser 15 when running into the bulk slag; The extrusion head end face becomes comb shape and bottom to extend in the middle of the grid 3, but combing falls to be stuck in slag between the grid slit like this, makes slag passage unimpeded all the time.
Adopt above technical scheme, big slag can not directly be dropped to carry on the steel band, avoided carrying the damage of steel band, the workload of single roller slag crusher 17 of output steel band outlet is reduced relatively, prolong the service life of single roller slag crusher, improved the comprehensive life of whole dry slag-draining device.Because the shape and the structure of extrusion head, the efficient of handling big slag is improved greatly, and the mediation passage of slag is unimpeded forever, so can reach in time, quickly big slag fragmentation be fallen and transfer out, to satisfy the working condition requirement of boiler, boiler can normally be moved safely.
