Description

conveyer belt system

Technical Field

Conveyor belt system the present invention relates to conveyor belt systems comprising a frame with a conveyor belt arranged to be driven by at least two rollers, whereby the upper belt serves as the conveying surface and the lower belt serves as the return.

Background

In most conventional conveyor belt systems, it is not possible to prevent such contaminants from contaminating the interior of the conveyor belt system, typical problems arise when contaminants fall on the lower belt as return oil.

The standard conveyor belt system has a frame and the conveyor belt protrudes through the wall of the frame at either sides so that the sides of the conveyor belt are outside of the frame because the edges of the conveyor belt are outside of the frame, contaminants that fall through the sides of the conveyor belt do not enter the interior of the frame.

Disclosure of Invention

Summary of the inventionit is an object of the present invention to provide conveyor belt systems having similarly reduced opportunities for wear and/or jamming, and having alternative configurations.

To this end the invention provides conveyor belt systems comprising a frame with a conveyor belt which is arranged to be driven by at least two rollers, whereby the upper belt serves as a conveying surface and the lower belt serves as a return surface, wherein the frame has an upper section extending substantially above the upper belt and a lower section extending substantially below the upper belt, wherein the upper section has at least two upstanding walls which are at a mutual spacing which is smaller at least at the location of the upper belt than the width of the conveyor belt, and wherein the lower section has at least two lower upstanding walls which are at a mutual spacing which is larger than the width of the conveyor belt, wherein the upper belt is supported on both sides by plates which extend from below the upper belt to the outside of the lower upstanding walls, respectively.

The conveyor system according to the invention provides boards under the edge of the upper belt of the conveyor belt, which boards extend outside the lower standing wall, the lower standing wall forms a lower section of the frame, which lower section extends substantially under the upper belt, the mutual spacing of the lower standing walls is larger than the width of the conveyor belt, contaminants moving above the conveyor belt edge fall on the boards, when these contaminants move on the boards , for example due to the running of the conveyor belt, due to the accumulation of contaminants due to vibration, the contaminants will eventually fall off the outer sides of the boards lower standing wall, due to the distance between the lower outer walls being larger than the width of the conveyor belt, the conveyor belt is located between or inside these lower standing walls, because the boards carry contaminants to the outer sides of the lower standing wall, these contaminants cannot reach the lower belt, because it is located inside the lower standing wall, 1 is provided on the side of the upper conveyor belt of the conveyor belt, the contaminants can be transferred to the point where the contaminants cannot reach the conveyor belt running, thus provides an alternative configuration for the conveyor belt, wherein the contaminants transfer to the conveyor belt 358, and the contaminants can be transferred to the conveyor belt 468, and/or provide a similar arrangement where the contaminants can be transferred to the conveyor belt 468, and the conveyor belt may be transferred to the conveyor belt 358, and/or may be transferred to the arrangement where the arrangement of the conveyor belt may be provided for the conveyor belt may be reduced with the conveyor belt, the conveyor belt 99, and the arrangement where the arrangement of the conveyor belt may be provided for the arrangement of the conveyor belt, where the conveyor belt may be provided for the conveyor belt, where the arrangement of the conveyor belt, where the conveyor belt may be found where the conveyor belt, where the contamination may be found where the conveyor belt, and/or the arrangement of the conveyor belt, may be found, the arrangement of the conveyor belt, may be found, the conveyor belt found, may be found, and the arrangement of the conveyor belt, may be found, may.

The plate preferably has a th section for supporting the upper belt and a second section for discharging contaminants, the second section more preferably discharging at least partially in a direction away from the conveyor belt at least at the location of the second portion, the upper side of the plate is more preferably at least partially free of obstructions so that contaminants can move on the plate from the th portion to the outer edge of the plate.

The friction between the plate and the conveyor belt can be optimized by dividing the belt into two portions, with portions placed on lateral sides of the conveyor belt, respectively.

The upper upstanding walls are preferably provided with seals at the location of the conveyor belt so that material on the conveyor belt is confined between the upper upstanding walls. The seal reduces the number of particles that can move outside the operating area of the conveyor. The operating area is defined here as two areas on the upper belt, which areas serve as conveying surfaces, between two upper standing walls. The operating area is used for conveying and guiding the material during the conveying process from the feeding to the discharging of the conveyor belt. The seal minimizes leakage.

In both cases, an airflow from the outside of the seal to the working area of the conveyor belt will be created by the pressure differential, and therefore particles present at the location of the seal will tend to move to the working area conveyor belt due to the airflow, which minimizes leakage.

The seal is preferably disposed on any side of the plate laterally of the conveyor belt above segment the th segment of the plate is located below the conveyor belt edge the th segment of the plate thereby supports the conveyor belt at the location of the edge by locating the seal at the th segment of the plate, the seal can be configured to exert a compressive force on the conveyor belt that is directly absorbed by the plate, thereby improving contact between the plate and the conveyor belt in and improving sealing in .

The lower standing wall preferably extends to a height below the lower belt. When the lower standing wall extends to a height below the lower conveyor belt, contaminants falling from the plates on the outside of the lower falling wall cannot fall onto the lower conveyor belt.

The upper section preferably comprises a roof element extending between two upstanding walls to enclose the transport surface. The top element also provides a shield to the working area of the conveyor belt so that material is not blown off the conveyor belt by the influence of ambient wind.

The conveyor belt is preferably substantially centered in the transverse direction with respect to at least of the two upper and two lower upright walls and the plate.
