Abstract
The utility model discloses a connection structure of fluidized bed feeder casing and transmission shaft, including casing, bearing frame, conveyer belt and transmission shaft, the casing both sides are provided with the curb plate respectively, the conveyer belt is installed on the transmission shaft, and the transmission shaft is installed on the curb plate, the bearing frame is installed respectively at the transmission shaft both ends to arrange the curb plate outside in, still be provided with seal part between transmission shaft and the curb plate, and adopt labyrinth seal. The utility model discloses a change the casing structure to sealed between increase transmission shaft and the casing, solution host computer wheel bearing end to end damages easily, changes difficult scheduling problem, and then reaches maintenance convenience, change portably, and extend bearing life, messenger boiler operation safety, stability have good safe protectiveness and economic benefits, can extensively popularize and apply at phosphorus chemical production technical field.
Description
Technical field
The utility model belongs to phosphorous chemical industry production technical field, specifically relates to the connection structure of a kind of fluid bed feeder casing and transmission shaft.
Background technology
The feeder of current use is primarily of part compositions such as coal bunker export coal gate, top coal spout and adjustable joint, feeder main frame, coal breakage bucket, feeder export coal gate, bottom coal spout and adjustable joint, microprocessor control systems.In fluidized-bed combustion boiler, a large amount of coal conveyor used plays vital effect in rectification production process, it is the key equipment ensureing that boiler normally runs, but due to the restriction of feeder housing structure, bearing seat is mounted in feeder enclosure interior, owing to there is a large amount of dust in casing, thus can not solve host header tail-gear spindle bearing and hold damageable problem.Make feeder end to end wheel bearing usually because lubricating maintenance can not be obtained in time, and easily enter coal dust and lubricating oil lost efficacy, and then destruction bearing, cause equipment to stop transport, boiler can be caused to break the serious consequences such as coal.
Utility model content
The purpose of this utility model is, for the deficiency existing for existing feeder, to provide the connection structure of a kind of fluid bed feeder casing and transmission shaft.Solve feeder wheel bearing not easily maintaining and hold damageable problem end to end, thus avoid bearing damage, reach that coal conveyor is long-term, the object of smooth operation.
The utility model is achieved by following technical solution.
The connection structure of a kind of fluid bed feeder casing and transmission shaft, comprise casing, bearing seat, load-transfer device and transmission shaft, described casing both sides are respectively arranged with side plate, described load-transfer device is arranged on transmission shaft, transmission shaft is arranged on side plate, described bearing seat is arranged on transmission shaft two ends respectively, and is placed in outside side plate.
Also sealing element is provided with between described transmission shaft and side plate.
Described sealing element adopts labyrinth.
Described casing employing thickness is the steel plate processing of 3mm.
Described side plate adopts thickness to be that the steel plate of 3mm and casing are weldingly connected.
Described load-transfer device is nylon belt.
The material of described casing and side plate all adopts Q235-A.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is by changing casing structure, thus seal between increase transmission shaft and casing, solve host header tail wheel bearing and easily damage, change the problems such as difficulty, and then it is convenient to reach maintaining, change easy, extend bearing service life, make boiler operatiopn safety, stable, there is good safety control and economic benefit, can in phosphorous chemical industry production technical field wide popularization and application.
Accompanying drawing explanation
Fig. 1 is the utility model fluid bed feeder structural representation.
In figure: 1-casing, 2-bearing seat, 3-load-transfer device, 4-transmission shaft, 5-side plate, 6-sealing element.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, the connection structure of a kind of fluid bed feeder casing described in the utility model and transmission shaft, comprise casing 1, bearing seat 2, load-transfer device 3 and transmission shaft 4, described casing 1 both sides are respectively arranged with side plate 5, described load-transfer device 3 is arranged on transmission shaft 4, transmission shaft 4 is arranged on side plate 5, and described bearing seat 2 is arranged on transmission shaft 4 two ends respectively, and is placed in outside side plate 5.Adopt the technical program, feeder, in operational process, because bearing seat 2 is arranged at outside side plate, makes bearing seat 2 be separated with the coal dust of casing 1 inside, thus reduces the coal dust entering Bearing inner, and then extends the service life of bearing; Simultaneously because bearing seat 2 adopts external mode, be convenient to timely make-up oil, if bearing normally damages, be also convenient for changing bearing.
Sealing element 6 is also provided with between described transmission shaft 4 and side plate 5.The impact of the external side shaft holder of further minimizing coal dust.
Described sealing element 6 adopts labyrinth.It has the effect of local contraction and expansion, to reduce the annular stricture passage leaking ash quantity, thus forms labyrinth seal to side plate 5, reaches good sealing effectiveness.
Described casing 1 adopt thickness be 3mm steel plate processing.Adopt the steel plate handling ease of 3mm thickness, easy to make, install simple and direct, low price.
Described side plate 5 adopts thickness to be that the steel plate of 3mm and casing 1 are weldingly connected.
Described load-transfer device 3 is nylon belt, is driven by great wheel actuating device.Great wheel actuating device is that motor or motor directly connect with reductor, and when it rotates, drive reductor to rotate, reductor drives great wheel running, thus whole piece belt is operated.
The material of described casing 1 and side plate 5 all adopts Q235-A.Adopt its structural strength of Q235-A steel good, applied widely, low price, is easy to buying.
The utility model is suitable for fluidized-bed combustion boiler feeder and uses, and in the occasion that coal dust is larger, effectively can reduce the damage of dust for bearing, improves maintaining effect, extends bearing service life, improves Homes Using TV, reduce over-the-road expense, ensure boiler operatiopn safety.
