Description

Unpowered roller brush cleaning device

technical field

The invention belongs to auxiliary equipment of a belt conveyor for bulk materials, in particular to a cleaning device for a belt conveyor.

Background technique

At present, the transportation of bulk materials in iron and steel metallurgy, electric power, coal and chemical enterprises mainly relies on belt conveyors. The cleaning effect of the return section of the tape directly affects the working environment and the normal operation and maintenance of the equipment. The cleaning devices currently in use cause consumption of a large amount of wear-resistant materials (frequent regular replacement of scrapers) and energy consumption (when electric roller brush cleaners are used in large quantities, the power consumption of the geared motor is large) while satisfying the cleaning effect. Combined with the current continuous improvement of energy-saving and environmental protection requirements for industrial production, the cleaning device should have functions such as low power consumption, low material loss, and high functional efficiency.

At present, domestic ordinary belt conveyor empty section cleaning devices are divided into P-type/H-type head cleaning devices, V-shaped empty section cleaning devices and roller brush cleaning devices. The above cleaning devices can be divided into two categories: plate contact type and rolling contact type.

Among them, the plate contact type (P-type/H-type head cleaning device, V-type empty section cleaning device) mainly relies on the scraper made of wear-resistant materials (such as polyurethane) to directly contact the conveyor belt to scrape off the particles attached to the belt. The material remains, but the long-term wear causes damage to the tape and the scraper of the cleaning device, which ultimately affects the cleaning effect.

The rolling contact type (rolling brush cleaning device) relies on the deceleration motor or the pinch wheel to drive the rolling brush roller to remove the material residue attached to the tape, but the power is provided by the deceleration motor or the pinch wheel, thus consuming energy or wearing the tape. Moreover, the working environment of the belt conveyor is harsh. After working for a long time, dust can easily enter the geared motor, causing damage to the motor, or damage to the belt and pressure pulley due to long-term work, which affects normal use and increases the daily maintenance of the equipment.

Contents of the invention

The technical problem to be solved by the present invention is to provide a non-powered rolling brush cleaning device with no wear to the tape, no additional energy consumption, simple structure and low cost for the above-mentioned defects of the prior art.

The present invention adopts following technical scheme for solving its technical problem:

The unpowered roller brush cleaning device includes a roller brush and a transmission mechanism, and is characterized in that: the roller brush is parallel to the reversing roller of the belt conveyor; the roller brush is in close contact with the tape of the belt conveyor; The roller brush bearing seat is hung on the lower end of the main beam, and the roller brush is installed between the two bearing seats; a transmission mechanism is set between the extension shaft of the roller brush and the extension shaft of the reversing roller, and the reversing roller drives the roller brush to rotate through the transmission mechanism And clean the tape.

According to the above technical solution, the transmission mechanism is a chain drive or a belt drive; correspondingly, sprockets or pulleys are arranged on both ends of the extension shaft of the rolling brush and the extension shaft of the reversing roller, and the chains are connected between the sprockets. , The pulleys are connected by belts.

According to the above technical solution, the chain or the belt is equipped with a guard outside.

According to the technical scheme, the rolling brush adjusts its rotational speed through the speed ratio of the two sprockets or the two pulleys.

The roller brush bearing seat is hung under the main beam on the upper part of the reversing roller of the belt conveyor, and the cleaning roller brush is installed between the two bearing seats. The driven sprocket is installed on the shaft stretched out from the two ends of the roller brush. A drive sprocket is installed on the extension shaft of the reversing roller of the belt conveyor, and the two sprockets are connected by a chain. Chain guards are mounted on the outside. The power of the roller brush cleaning device is provided by the reversing roller of the belt conveyor, so no additional energy consumption is generated. The roller brush adjusts its rotation speed through the speed ratio of the two sprockets to achieve the best effect of tape cleaning.

The beneficial effects of the present invention are mainly:

1. No abrasion to the tape. The cleaning device adopts a rolling brush roller to avoid direct contact between the large-area scraper and the tape, avoiding the wear of the tape and the cleaner, so that the cleaning device can be used for a long time.

2. No additional energy consumption, saving cost. The power source of the cleaning device comes from the belt conveyor equipment body, which effectively saves energy consumption. And because the cleaning device does not need to provide additional power supply and control, it saves the project's investment in electrical and automation control, thereby reducing equipment costs, reducing maintenance work during equipment operation, and reducing equipment spare parts.

3. The operation of the equipment is synchronized with the belt conveyor without human control; it simplifies the operation in normal production and reduces the workload of daily equipment maintenance.

4. The structure is simple. The cleaning device has a simple structure and is easy to install and disassemble.
