The slag extractor comprises a slag spout, and is characterized in that a motor and a transmission box are arranged on the left upper side of the slag spout, a slag hole is arranged on the left lower side of the slag spout, an inlet connecting flange and an access hole are arranged on the right upper side of the slag spout, a bottom shaft is arranged on the right side of the slag spout, lower guide wheels are mounted on the bottom shaft, a movable access passage is arranged between the bottom shaft and the access hole, the motor and the transmission box are connected with anchor driving sprockets through chains, the anchor driving sprockets are connected with the lower guide wheels through anchor chains, and a scraper plate is arranged on the anchor chains. Compared with the prior art, the slag extractor with a movable bottom shaft has the advantages that sliding copper sleeve bearings bear small friction force, have fine wear resistance, service lives of the bearings are prolonged to over one years from the original one to two months, the bottom shaft can be detached integrally and is convenient to maintain, wherein the maintain time is shortened to two hours from the original six to eight hours.
Description
Technical field
The utility model relates to a kind of coal furnace cinder conveying device, is specially a kind of movable lower shaft mucking machine.
Background technology
Coal-burning boiler is widely used in the chemical engineering industry heating system, and the original mode of slagging tap is purely manually to slag tap, not only the labour intensity height, and the unlatching of cleanout door is excessive to the negative pressure influence of stove when slagging tap, cause pressure combustion, the badly damaged body of heater of pressure combustion meeting causes serious potential safety hazard.Present large-tonnage coal-burning boiler adopts machinery to slag tap more, and wherein the use of screw rod mucking machine and scraper-type mucking machine is the most general, but the screw rod mucking machine is too high to the granularity requirements of cinder, stuck fault pilosity, maintenance difficult.The scraper-type mucking machine is less demanding to cinder, structure is directly perceived, easy to maintenance, but existing scraper-type mucking machine bottom bearing structure is too simple, and set single copper sheathing bearing very easily weares and teares, cause balance to be destroyed, anchor chain stretches uneven, and fault rate is too high, and the life-span is too short, safeguard also and comparatively require great effort, need To be improved.
The utility model content
At problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme of movable lower shaft mucking machine.
Described a kind of movable lower shaft mucking machine, comprise dirt-excluding groove, it is characterized in that described dirt-excluding groove upper left side is provided with motor and gearbox, the lower left sets out cinder notch, the upper right side is provided with inlet adpting flange, access hole, described dirt-excluding groove right side also is provided with lower shaft, and lower tumbler is installed on the lower shaft, and movable maintenance slideway is set between lower shaft and the access hole; Described motor is connected with the anchor chain drive sprocket by chain with gearbox, and the anchor chain drive sprocket connects lower tumbler by anchor chain, and described anchor chain is provided with scraper plate.
Described a kind of movable lower shaft mucking machine is characterized in that described lower shaft two ends are provided with bearing block respectively, and bearing block is spirally connected by bolt and dirt-excluding groove.
Described a kind of movable lower shaft mucking machine is characterized in that setting sets gradually bearing, first sealing, axle sleeve, second sealing between described bearing block and the lower tumbler.
Described a kind of movable lower shaft mucking machine is characterized in that described axle sleeve outside socket is provided with copper sheathing.
The utility model compared with prior art has following advantage: slip copper sheathing bearing is only born very little frictional force, and anti-wear performance is good, and brought up to 1 year or more by 1 original～February service life; Lower shaft can wholely split, and easy to maintenance, shortened to 2 hour by 6～8 hours maintenance time.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a profile of the present utility model;
Fig. 3 is an A portion enlarged drawing among Fig. 2.
The specific embodiment
Below in conjunction with Figure of description the utility model is described further:
As shown in the figure, a kind of movable lower shaft mucking machine, comprise dirt-excluding groove 1, described dirt-excluding groove 1 upper left side is provided with motor and gearbox 6, and the lower left sets out cinder notch 5, and the upper right side is provided with inlet adpting flange 2, access hole 3, described dirt-excluding groove 1 right side also is provided with lower shaft 12, lower tumbler 13 is installed on the lower shaft 12, movable maintenance slideway 4 is set between lower shaft 12 and the access hole 3, can realize quick integral dismounting function; Described motor is connected with anchor chain drive sprocket 9 by chain with gearbox 6, and anchor chain drive sprocket 9 comes adjusting position by the tensioning apparatus 8 of arranged outside, and anchor chain drive sprocket 9 connects lower tumbler 13 by anchor chain 10, and described anchor chain 10 is provided with scraper plate 11.
Described lower shaft 12 two ends are provided with bearing block 15 respectively, bearing block 15 is spirally connected by bolt 22 and dirt-excluding groove 1, be provided with between bearing block 15 and the lower tumbler 13 and set gradually bearing 16, first sealing 17, axle sleeve 14, second sealing 19, described axle sleeve 14 is made for the high-strength abrasion-proof material, its outside socket is provided with copper sheathing 18, copper sheathing 18 cooperates with axle sleeve 14, plays labyrinth seal and sliding bearing, and bearing 16 and copper sheathing 18 are realized sealing by first sealing, 17, second sealing 19 respectively.
The utility model is from hanging down to height with cinder, the deslagging device that long distance is carried, inlet adpting flange 2 is connected with the slag notch of coal stove, is full of water in the dirt-excluding groove in advance, sees the waterline 20 of Fig. 1, when cinder falls into dirt-excluding groove 1, and behind the water logging bubble, sinking to the bottom, the scraper plate 11 that is provided with on the anchor chain 10 clockwise rotates under the drive of anchor chain drive sprocket 9, when scraper plate 11 passes through the bottom, the cinder 21 that falls swept and promote be transported to slag notch 5, realize that circulation carries.
During operation, 18 of copper sheathings bear very little frictional force, and anti-wear performance is good, service life is by 1 original～February, brings up to more than 1 year; But movable lower shaft part integral disassembly, assembly, easy to maintenance, shortened to 2 hour by 6～8 hours maintenance time, saved time and manpower, and optimized the anti-wear performance of equipment, reduces cost.
