Description
Technical field
What the invention belongs to coal burning boiler dry ash extraction equipment manufactures and designs field, particularly a kind of anti-material spilling structure for boiler slag removal cooling conveying device upper conveyor belt.
Background technology
The solid bulk material of the heat produced in the production technologies such as coal burning boiler is by carrying/cooling mechanism transport; due to the flowable of bulk material or in seal case cooling-air effect under, some tiny material particles or dust can be scattering into outside load-transfer device or bottom by the gap of load-transfer device.For this reason, in the bottom of load-transfer device, usually design has the scraping clearing apparatus of chain or metal gauze, by the tiny material particles of seal case bottom deposit or lime-ash to discharge zone transmission.Such as, namely Chinese patent literature CN1646860B discloses a kind of transmission/cooling mechanism of the hot loose material for producing in boiler and various industrial process, arriving load-transfer device for preventing the hot downward expansion of the deflecting plate of seal case from scratching, the gap of about 5-40mm must be retained bottom metal conveyor belt upper surface and short side panel; Because metal conveyor belt inevitably occurs belt deflection phenomenon when carrying hot loose material, therefore metal conveyor belt two side shield and deflecting plate bottom vertical part also must reserve the gap of 10-30 about mm; Like this, in seal case cooling-air effect under, some tiny lime-ash can the gap overflow bottom metal conveyor belt baffle plate and deflecting plate be scattering into outside load-transfer device or bottom, therefore, chain clearing apparatus is set in the bottom of metal conveyor belt, container bottom is deposited tiny lime-ash to discharge zone transmission.Owing to must install a set of chain clearing apparatus by customized design in the bottom of load-transfer device or other board-like conveyers, this chain scraper clearing apparatus needs independently to drive and speed reduction gearing, and therefore the cost of investment of equipment is very high.In addition, due to chain clearing apparatus, be all drive scraper plate or hopper by chain traction, owing to there are serious wearing and tearing, a large amount of engineering operation facts have proved, about 1-2 chain, scraper plate or hopper all need all or major part is changed.
Summary of the invention
For this reason, technical matters to be solved by this invention is to provide a kind of feedway Anti-scattering structure that material can be prevented to be scattered down from feedway.
For solving the problems of the technologies described above, the invention provides a kind of Anti-scattering structure of bulk material feedway, comprising the baffle plate being arranged at load-transfer device both sides along throughput direction; Be fixedly installed on the roof of casing and to the deflecting plate of downward-extension, described casing is positioned at the surrounding of described load-transfer device, and described deflecting plate is between described baffle plate and the upper surface of its bottom and described load-transfer device is provided with gap; And be arranged at described load-transfer device two ends, for the flexible seals preventing bulk material from overflowing from the gap between described deflecting plate and described baffle plate.
Described flexible seals is arranged at the inner side of described deflecting plate, and the sealed end of described flexible seals fits on described load-transfer device.
The installation end of described flexible seals is connected to the medial shaft straight section of described deflecting plate, and the relatively described deflecting plate upper-lower position of described flexible seals is adjustable.
The installation end of described flexible seals is connected on the roof of described casing.
Described flexible seals is arranged in the gap between described deflecting plate and described baffle plate.
Described flexible seals is horizontally set between described deflecting plate and described baffle plate, and the sealed end of described flexible seals fits on the plate face of described baffle plate or described deflecting plate.
Described flexible seals is longitudinally arranged between described deflecting plate and described baffle plate, the sealed end of described flexible seals fits on described load-transfer device, its installation end is connected to the outside upright section of described deflecting plate, and the relatively described deflecting plate upper-lower position of described flexible seals is adjustable.
Described flexible seals is arranged at the bottom of described deflecting plate, and the sealed end of described flexible seals fits on described load-transfer device, and its installation end is connected on described deflecting plate.
Described flexible seals is arranged continuously along the length direction of described load-transfer device.
Described flexible seals is the bar shaped silk brush made of metallic material or high temperature resistant non-metal sealing band.
Technique scheme of the present invention has the following advantages compared to existing technology:
(1) the present invention is overflowed from the gap between the baffle plate and deflecting plate of conveyer belt both sides to prevent bulk material, is provided with a flexible seals in the both sides of load-transfer device; Its from root solve material on load-transfer device or other board-like conveyers in course of conveying the overflow of fine particle to be scattered phenomenon, independent chain scraper clearing apparatus or annular chain bucket fines regenerative apparatus is needed to be used for receiving the fallen lime-ash of load-transfer device compared to existing traditional conveyer, the repair and maintenance brought thus and the high problem of operating cost, Anti-scattering structure of the present invention makes the structure design of conveyer simpler, compact, and equipment cost reduces greatly.The sealed end of this flexible seals is in contact with it face and achieves flexible sealing, avoids the bite phenomenon of load-transfer device that positiver sealing may occur or board-like conveyer simultaneously.
(2) according to different usage conditions, this flexible seals can be installed on the inner side of deflecting plate, between baffle plate and deflecting plate, or the downside of deflecting plate, which form the multiple different barrier preventing fine particle (as ash) to be scattered, from preventing being scattered of material.
(3) the flexible seals of the present invention bar shaped silk brush of selecting metallic material to make or high temperature resistant non-metal sealing band, it has certain rigidity, can not play the effect of sealing after preventing bulk material that load-transfer device is piled up from causing being out of shape to its extruding; Meanwhile, its sealed end is in contact with it between face and forms flexible sealing, prevents load-transfer device bite phenomenon.
(4) flexible seals of the present invention is arranged continuously along the length direction of load-transfer device, guarantees the effect of the anti-material spilling of whole piece load-transfer device.
