Abstract
The utility model discloses a novel roll type drawing template submerged chain conveyor which is composed of an upper box body and a lower box body. The upper box body is a work box of the submerged chain conveyor and is composed of a drive set, a chain and a plurality of drawing templates arranged on the chain; and the lower box body is a return box for the drawing templates and the chain. A carrier roller device and an orbit device are arranged at the inner side of the drawing template submerged chain conveyor; a carrier roller and a carrier roller yoke plate are symmetrically arranged at the end parts of the drawing templates of the submerged chain conveyer; orbits are symmetrically arranged at two sides of the inner side of the drawing template submerged chain conveyor; and the carrier roller is arranged on the orbits. Another scheme is as follows: the carrier roller and the carrier roller yoke plate are symmetrically arranged behind the end parts of the drawing templates of the submerged chain conveyor; the diameter of the carrier roller is slightly bigger than the height of each drawing template; and orbits on which the carrier roller can roll are arranged below the carrier roller. The device changes the sliding moving mode of the drawing template of the submerged chain conveyor into the rolling moving mode, thereby avoiding the sliding-frictional resistance, further greatly reducing the driving moment of the submerged chain conveyor, avoiding abrasion and clamping stagnation of the drawing templates and a soleplate, reducing the workload of overhauling and maintenance, and improving the running reliability of the submerged chain conveyor.
Description
Technical field
The utility model relates to a kind of chain scraper conveying equipment of bulk material, is the chain scraper slag dispatch equipment that a kind of coal-burning boiler is used specifically.
Background technology
At present, coal-burning boiler, particularly the slagging-off mode of thermal power generation station-service coal-burning boiler adopts the chaindriven scraper-type dragveyer of annulus mostly, this scraper-type dragveyer be by scraper plate do not stop in the boiler bottom tank, do slide displacement, thereby slag is constantly discharged from boiler bottom, because the scraper plate quantity of dragveyer is many, and and be sliding friction operation between base plate, frictional resistance is big, so shortcoming such as have that driving moment is big, easily clamping stagnation overload chain rupture, scraper plate wearing and tearing are big, have influence on the continuous operation of boiler plant, cause bigger economic loss.
Summary of the invention
The purpose of this utility model is to provide a kind of new-type rolling formula scraper plate device for dragging dregs, it is by the scraper plate with the dragveyer sliding and running, change rolling-operation into, the sliding friction that is about between scraper plate and the base plate changes rolling friction into, significantly reduce the operation frictional resistance of scraper plate, thereby reduce the driving moment of dragveyer, prevent clamping stagnation, slow down and even avoid the scraper plate wearing and tearing.
The technical solution of the utility model is as follows:
The utility model is realized by two kinds of schemes:
This device is made up of two casings up and down, and upper box is the work box of dragveyer, and it is made of drive unit, chain and a plurality of scraper plates of being connected on the chain, and lower box is the backhaul case of scraper plate and chain; At submerged slag conveyor disposed inboard support roller device and rail set, above-mentioned support roller device is made up of rotating carrying roller and carrying roller yoke plate, be arranged symmetrically in the end of dragveyer scraper plate, carrying roller connects scraper plate through the idler pulley yoke plate, above-mentioned rail set is made up of track and track support, be arranged symmetrically in the inboard both sides of submerged slag conveyor, track fixedly is connected in through track support on the side box plate of dragveyer, and carrying roller rides on the track; Thereby scraper plate is lifted, make it and the dragveyer base plate between gapped, thereby eliminate the sliding friction of scraper plate and dragveyer base plate.
Another program of this device is made up of two casings up and down, and upper box is the work box of dragveyer, and it is made of drive unit, chain and a plurality of scraper plates of being connected on the chain, and lower box is the backhaul case of scraper plate and chain; On the dragveyer scraper plate, adorn support roller device, this support roller device is made up of rotating carrying roller and carrying roller yoke plate, be arranged symmetrically in the back, end of dragveyer scraper plate, carrying roller connects scraper plate through the carrying roller yoke plate, the slightly larger in diameter of carrying roller is adorned track in the height of scraper plate under carrying roller, it is the straight track that is tiled on the base plate, be used for supporting carrying roller, carrying roller rolls thereon.
Above-mentioned track is made by steel plate or other high-abrasive material.
Advantage of the present utility model is: 1, this device greatly reduces the operation frictional resistance of the scraper-type dragveyer that coal-burning boiler uses, and has promptly reduced the driving moment of dragveyer.2, this device has been avoided the sliding friction loss that the dragveyer scraper plate produces with direct contact of base plate.3, this device has effectively been avoided the clamping stagnation and the chain rupture of scraper plate.4, the carrying roller of this device is changed easily, overhauls convenient and swift.

Fig. 6 is the vertical structure generalized section of the former slip submerged slag conveyor before improving;
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Can be seen that by Fig. 1-6 submerged slag conveyor is divided into two casings up and down, upper box is the work box of dragveyer, and the scraper plate that slag will be moved in this casing blows off, and lower box is the backhaul case of scraper plate and chain.
Can see the dragveyer structure of this device scheme one by Figure 12, this device mainly is made up of walking track 3 and carrying roller 2, track 3 is fixed on the side box plate 5 of dragveyer by track support 4,2 sides that are fixed on dragveyer scraper plate 7 by carrying roller yoke plate 1 of carrying roller, scraper plate 7 moves along track 3 by carrying roller 2, the gap that will keep 1-5mm between scraper plate 7 and the dragveyer cast stone base plate 8, when the chain 6 of dragveyer moves, then drive scraper plate 7, carrying roller 2 and on track 3, roll, thereby realize the rolling friction operation.The direction of marking is scraper plate, chain traffic direction among the figure.
Can see it being this device scheme two dragveyer structures by Fig. 3-4, this device is mainly by carrying roller yoke plate 1, carrying roller 9, track 10 is formed, yoke plate 1 symmetry is fixed on the rear portion, both sides of scraper plate 7, carrying roller 9 is fixed on the yoke plate 1, the diameter of carrying roller 9 is larger than the height of scraper plate 7, track 10 is flat plates, be fixed on the cabinet bottom, scraper plate 7 moves on track 10 by carrying roller 9, the gap that will keep 1-5mm between scraper plate and the dragveyer cast stone base plate 8, when the chain 6 of dragveyer moves, then drive scraper plate, carrying roller rolls in orbit, thereby realizes the rolling-operation of scraper plate.
Carrying roller rolls on floor rail, thereby scraper plate is lifted, and making between scraper plate and the dragveyer base plate has less gap, thereby eliminates the sliding friction of scraper plate and dragveyer base plate.
Fig. 5-the 6th without the improved dragveyer structure of the utility model, can see, the scraper plate 7 of dragveyer directly contacts with dragveyer cast stone base plate 8, and when chain 6 moved, chain 6 directly dragged scraper plate 7 sliding and running on cast stone base plate 8.
