Abstract
Conveyor belt cleaning equipment (5) comprises a plurality of flexible scraper or sweep elements (12) mounted on a driven endless belt (6) drivably arranged around two rollers (8 and 9) the flexible scraper or sweep elements on one run of the belt contacting the surface of the conveyor belt (1) to be cleaned. The roller 9 is preferably an idler roller and is adjustably mounted at 11. The belt 6 is preferably guided on the rollers 8, 9 by cooperating ribs on the belt and grooves in the rollers. <IMAGE>
Description
SPECIFICATION
Conveyor belt cleaning equipment
This invention relates to conveyor belt cleaning equipment.
In particular, the present invention relates to conveyor belt cleaning equipment comprising a scraper or sweep element assembly having at least one scraper or sweep element arranged to contact a currently non conveying surface of the conveyor belt thereby tending to scrape or sweep from that surface any material conveyed by the conveyor belt and adhering to the surface.
A prior known conveyor belt cleaning equipment comprised a plurality of transverse scraper elements mounted on an endless driven flexible component arranged around a plurality of pulleys such that as the component was driven in the same direction as the conveyor belt but at a slower speed than the conveyor belt the transverse scraper elements contacted the belt surface tending to scrape off any broken material adhering to the surface. In order to try and maintain the scraper elements in contact with the conveyor belt surface throughout the operational life of the elements it was necessary to provide a resilient support for all the belt cleaning equipment.The provision of such a support meant that such prior known belt cleaning equipment tended to be complicated and expensive and unsuited to prolonged use on dirty conditions frequently encountered on industrial conveyor belt installations.
An object of the present invention is to provide improved conveyor belt cleaning equipment which is suitable for prolonged use in industrial installation and which has an efficient cleaning action.
According to the present invention, conveyor belt cleaning equipment comprises an endless flexible component drivably arranged around at least two rollers, at least one of which is driven, and at least one flexible scraper or sweep element mounted on the driven flexible component and arrangable, in use, to contact a conveyor belt surface to be cleaned.
Preferably, a plurality of flexible scraper or sweep elements are mounted on the driven flexible component.
Advantageously, the endless flexible component is a belt.
Preferably, the endless flexible component is provided with guide means engageable with at least one of the rollers.
Advantageously, the endless flexible component is driven such that the or each flexible element is moving in a direction opposite to the direction of travel of the conveyor belt surface being cleaned.
The present invention also provides a conveyor belt installation including conveyor belt cleaning equipment as defined above.
By way of example only, one embodiment of the present invention will be described with reference to the accompanying drawings, in which:
Figure 1 is an incomplete diagrammatic side view of a discharge end of a conveyor belt installation including conveyor belt cleaning equipment constructed in accordance with the present invention; and
Figure 2 is an incomplete partly sectioned view of the cleaning equipment of Figure 1 looking in the direction indicated by arrow A of Figure 1, Figure 2 being drawn on a slightly enlarged scale compared to Figure 1.
Figure 1 of the drawings shows an incomplete diagrammatic side view of a discharge end of an endless conveyor belt 1 which, in use, conveyor, for example, broken rock or mineral material. The broken material is conveyed along the upper run of the belt towards a driven roller 2 drivably engaging the conveyor belt such that substantially all the broken material is ejected from the belt as it passes around the driven roller. The lower run of the conveyor belt leaves the drive roller and passes over a guide roller 4 before continuing its journey to a return roller (not shown) situated at the remote end of the conveyor where the conveyor belt is returned to the upper run travelling towards the driven roller 2.
Although substantially all the broken material is ejected over the discharge driven roller on to further conveyor means (not shown) a relatively small amount adheres to the conveyor belt surface and passes around the driven roller towards the lower run. In order to try and ensure the broken material adhering to the belt surface does not travel along the lower run to be deposited somewhere along the length of the conveyor belt, cleaning equipment 5 is provided beneath the driven roller 2.
The conveyor belt cleaning equipment (which is shown in Figures 1 and 2) comprises an endless flexible component constituted by a belt 6 drivably arranged around two rollers 8 and 9. The roller 8 is driven by means of gearing and a drive motor (not shown) which may be the drive motor for the conveyor belt. Alternatively, the cleaning equipment may have its own drive motor independent of the conveyor belt drive. Preferably, the drive roller 8 has a mounting 10 fixedly secured to the conveyor belt support structure (not shown). The roller 9 is an idler roller and is mounted in adjustable mounting 11 enabling the position ofthe roller9to be adjusted relatively to the conveyor belt surface to be cleaned and relatively to the drive roller 8 enabling the tension of the belt 6 to be adjusted to a desired level.
A plurality of flexible, upstanding scraper or sweep elements 12 are fixedly mounted on the endless belt 6, the flexible elements on one run of the belt being arranged to contact the belt surface to be cleaned to thereby scraper or sweep from the belt surface any broken material adhering to the surface.
Both edges of the belt 6 are provided with guide means constituted by inwardly directed projections 14 (see Figure 2) engageable in guide grooves 15 provided in the drive roller 8 to retain the belt in a desired position on the roller. Similar grooves may be provided in the roller 9, these latter grooves being in addition to or instead of the grooves 15.
In use, the assembled conveyor belt cleaning equipment is mounted on the conveyor belt support structure adjacent to the belt surface to be cleaned with the flexible scraper or sweep elements on one run of the belt 6 adjacent to the surface. The mounting 11 for the roller 9 then is adjusted until the associated scraper or sweep elements are contacting the belt surface and the reaction between these scraper or sweep elements and the belt surface is adjudged to be sufficient for the elements to scrape or sweep from the surface any broken material adhering thereto.
Once the cleaning equipment is instalied the drive motor is started to drive the belt 6 such that thwe flexible scraper or sweep elements move in a direction opposite to the direction of travel of the conveyor belt surface being cleaned. Broken material scraped or swept from the belt surface is conveyed by the belt 6 and discharged onto the previously mentioned further conveyor means.
After prolonged use and the flexible scraper or sweep elements start to wear the mounting 11 for the roller 9 is adjusted to maintain an adequate reaction force between the elements and the belt surface.
In other embodiments of theinvention the belt is driven so that the flexible scraper or sweep elements move in the same direction as the belt surface, the belt 6 being driven art a different speed to that of the conveyor belt 1.
From the above description it will be appreciated that the present invention provides conveyor belt cleaning equipment which is simple and in which the flexible scraper or sweep elements are maintained in contact with the belt surface being cleaned for a relatively long period.
