SU1705205A1 - Device for cleaning the conveyer belt - Google Patents

Abstract

The invention relates to a conveyor transport and is intended for the hydraulic cleaning of conveyor belts from a strongly adhered transported material. The goal is to intensify the cleaning process by treating each section of the conveyor belt with jets of working medium (PC) from different sides. A collector 1 with a hollow rotating element closed at one end is placed in the device case under the belt. The other end of the collector 1 is connected by a hollow rotary axis 3 with a chamber 9 with a nozzle 10 for supplying a PC. Nozzles 2 are placed on the rotating element for feeding the PC in opposite directions. The points of intersection of the axes of the nozzles 2 with the surface of the tape are on a common circle. The center of the circle coincides with the axis of rotation 3, and the diameter is equal to the width of the tape. Through pipe 10, chamber PC is supplied to chamber 9, which through axis 3 and collector 1, distributed through nozzles 2, flows out in the form of jets onto the surface to be cleaned. By adjusting the angle of inclination and the direction of the outflow of the jet PC, it is possible to choose the necessary rotational speed and the conditions for processing the tape. In addition, each section of the conveyor belt can be jetted from different directions, which improves the quality of cleaning. 4 il. (/

Description

The invention relates to a conveyor transport, in particular, to devices for the hydraulic cleaning of conveyor belts from a strongly adhering transported material.

The purpose of the invention is to intensify the cleaning process by treating each section of the conveyor belt with jets of working medium from different sides.

FIG. 1 shows a device for cleaning a conveyor belt, general view; in fig. 2 is a section A-A in FIG. 1; in fig. 3 and 4 are diagrams with one of the possible variants of the orientation of the jets of the working medium relative to the surface of the tape (the dotted line in FIG. 4 shows the trace left by the streams on the tape).

A device for cleaning the conveyor belt consists of a manifold 1 with nozzles 2, a vertical hollow axis 3 mounted with bearings 4, rings 5, a sleeve 6 and a cover 7 in the base housing 8. The chamber 9 with the outlet 10 is attached to the base housing 8 working medium, while the axis of the nozzle coincides with the axis of rotation 3. The housing of the base 8 is fixed on the pallet 11, installed under the idle branch of the conveyor 12.

The end of the hollow axis 3 protruding into the chamber 9 is sealed with the cuffs 13 and provided with a baffle ring 14. The cavity of the chamber 9 is connected via a hollow axis of rotation 3 to the cavity of the collector 1. Along the collector 1, the nozzles 2 are installed at different angles of inclination and on opposite sides of the vertical plane passed through the axis of the collector and the axis of rotation under the following conditions:

The device for cleaning the conveyor belt operates as follows.

The working medium is supplied through the nozzle 10 to the chamber 9, then through the hollow axis 3 to the collector 1, and from the collector the working medium, distributed through the nozzles 2, flows out in the form of jets to the surface to be cleaned. Due to the fact that the nozzles are placed at different distances from the axis of rotation and

cloned at different angles; different torques occur at the attachment points of the nozzles. And since part of the nozzles is directed in the opposite direction, the torques are directed in opposite directions, partially compensating each other.

By adjusting the tilt angles and the direction of the outflow of the jets, it is always possible to select the required rotational speed and processing conditions of the belt, and the direction of rotation is determined by the presence of excess torque on one side.

Thus, the device allows adjusting the speed of rotation of the collector and at the same time maintaining the optimum tilt angles of the working medium jets, as well as processing each section of the conveyor belt with jets from different directions. which ultimately leads to an improvement in the quality of cleaning and to a reduction in the processing time of the conveyor belt.
