Abstract

The utility model provides an external transmission of a scraper conveyor of a fluidized bed, which comprises a fluidized bed shell, a transmission shaft and a driver. The transmission shaft provided with a sprocket is arranged in the shell, and the driver is disposed outside the shell and connected with the transmission shaft. The external transmission is characterized in that a bearing and a bearing block which support the transmission shaft are arranged outside the fluidized bed shell. As the bearing and the bearing block which support the transmission shaft are disposed outside the fluidized bed shell, damage to the bearing due to a high-temperature, high-humidity and high-dust environment of the fluidized bed is avoided effectively, the service life of the bearing is prolonged, simultaneously, when the bearing needs to be replaced, the fluidized bed shell does not need to be detached, the bearing can be replaced outside the shell, time and labor are saved, coal moisture control operation is unaffected, normal production of a coke oven is guaranteed, and maximum economic benefit is realized for an enterprise.

Description

Fluid bed scraper plate machine external driving device

Technical field

The utility model relates to a kind of driving device, and particularly a kind of fluid bed scraper plate machine external driving device belongs to machine design manufacturing technology field.

Background technology

In coke production,, maximally utilise fume afterheat for reducing production costs; Need and will feed in the fluid bed with the flue gas of temperature, in fluid unit, feed coal and high-temp waste gas carry out interchange of heat; Make the moisture content in the coal be reduced; Thereby stablize coke oven production, reduce the coking energy consumption, and improve coke quality, realizes energy-conservation, consumption reduction, reduction of discharging.Therefore, fluid bed is in the environment of high temperature, high humidity, high dust all the time.In the prior art; The bearing and the bearing seat that support the driving device of fluid bed scraper plate machine operation also are arranged in the fluid bed housing, and bearing and bearing seat also are in high temperature, high humidity, the high dust atmosphere for a long time, very easily lose sealing function because of seal ring is aging; And make oil leak because of seal failure; Thereby lose lubricating effect, cause wear-out of a bearing serious, even be corroded.Condense into piece because of seal failure makes dust get into the back with lubricating oil simultaneously, further quicken wear-out of a bearing, even cause bearing failure; And when needs are changed bearing, must stop fluid bed production, behind the dismounting fluid bed housing; Just can change; Not only waste time and energy, and can influence the coke oven ordinary production, bring economic loss to enterprise because of coal damping inefficacy.Therefore be necessary prior art is improved.

Summary of the invention

For solving existing bearing and the bearing seat that supports the driving device of fluid bed scraper plate machine operation; Because of being arranged in the seal failure that the fluid bed housing brings; Oil leak; The wear-out of a bearing aggravation, problems such as bearing replacing difficulty, the utility model provides a kind of fluid bed scraper plate machine external driving device.

The utility model is accomplished through following technical proposal: a kind of fluid bed scraper plate machine external driving device; Comprise the fluid bed housing and place in the housing its to go up the transmission shaft that band chain is taken turns; And place outside the housing and the actuator that links to each other with transmission shaft; The bearing and the bearing seat that it is characterized in that supporting shaft are located at outside the fluid bed housing, to constitute external bearing and bearing seat, prevent the damage to bearing of high temperature and coal dust.

Said bearing seat is fixed on the fluid bed housing wall through support, installs, dismantles, changes with convenient.

Said bearing seat is fixed on the ground through support, installs, dismantles, changes with convenient.

The utlity model has advantage and effect: adopt such scheme, the bearing of supporting shaft and bearing seat are placed outside the fluid bed housing, the damage of effectively having avoided high temperature, high humidity, high dust atmosphere in the fluid bed to cause to bearing; Prolonged bearing service life; When needs are changed bearing, need not to dismantle the fluid bed housing simultaneously, only need outside housing, just to operate and to accomplish replacing; Time saving and energy saving; Do not influence coal damping operation, ensure the coke oven ordinary production, bring maximum economic benefits to enterprise.

Description of drawings

Fig. 1 is the structural representation of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done and to be further described.

Like Fig. 1; The fluid bed scraper plate machine external driving device that the utility model provides; Comprise fluid bed housing 2 and place in the housing 2 its to go up band chain and take turns 3 transmission shaft 4; And place outside the housing 2 and the driving retarder 1 that links to each other with transmission shaft 4, wherein the bearing of supporting shaft 4 and bearing seat 5 place outside the housing 2, and are fixed on the fluid bed housing 2 through support 6.

Claims

1. fluid bed scraper plate machine external driving device; Comprise the fluid bed housing and place in the housing its to go up the transmission shaft that band chain is taken turns; And place the actuator that housing is outer and link to each other with transmission shaft, it is characterized in that the bearing of supporting shaft and bearing seat be located at outside the fluid bed housing.

2. fluid bed scraper plate machine external driving device according to claim 1 is characterized in that said bearing seat is fixed on the fluid bed housing wall through support.

3. fluid bed scraper plate machine external driving device according to claim 1 is characterized in that said bearing seat is fixed on the ground through support.
