Description

The invention relates to conveyor transpspton, namely, devices for cleaning the conveyor belt, and is an improvement to the device according to the author. No. 1093653.

The aim of the invention is to improve the reliability and operation of the device due to the automatic cleaning of the gap for the exit of exhaust air from viscous material transported by a conveyor,

. Fig. 1 shows a device for cleaning a conveyor belt; in fig. 2 shows section A-A in FIG. one; on .fig. 3 - the same, at the time of cleaning the gap and the main scraper with an additional scraper;

The device for cleaning the conveyor belt comprises a housing 1, made in the form of a pipe installed in supports 2 and 3. One end of the pipe is connected to a reciprocating mechanism 4. The lower 5 and upper 6 grooves are made in the pipe, into which the main scraper 7 is inserted with the possibility of vertical movement, a gap 8 forming the wall of the upper groove 6, and an additional scraper 9, which is equal to the width of the gap 8. The latter is made on the side of an additional scraper 9 and serves to expel waste air from mechanism 4.

Additional scraper. 9, having an air bypass channel 10, is fixed on the main scraper 7 with along the guides 11 and has the possibility of reciprocating relative to the main scraper 7 and the body 1 under the influence of the power cylinder 12, which is mounted on the body 1 and operates from

Thus, the additional scraper automatically cleans the gap and the main scraper, which significantly increases the reliability of the air distributor 13 according to the signal

pressure sensor 14. Control pressure — 45 devices, eliminating the need

Sensor 14 is obtained from the internal manual cleaning of the device.

The cavity of the housing 1 through the air 15.

The device works as follows.

The exhaust air from the mechanism 4 of the reciprocating movement enters the internal cavity of the housing 1 and exits the gap S, blowing off the tape cleaning products from the main scraper 7.

In the case of transportation of viscous materials, part of them remains on the main scraper 7 and as they accumulate, the gap 8 becomes clogged. There comes a time when the air stops flowing out of the gap 8 and the device stops working. through duct 15

affects the pressure sensor 14. The sensor switches the air distributor 13, which communicates the cavity of the power Dalindra 12 with a source of compressed air. The cylinder lifts the additional scraper 9 along the bottom 1 1 along the main scraper 7 and leads it into the gap 8, pushing the tape cleaning products from the gap pushing it out of the gap. When reaching the final position, the additional scraper 9 communicates the internal position of the housing 1 through the air bypass channel 10 with the atmosphere. The pressure in the internal cavity drops and the sensor

the pressure is signaled, the air distributor switches, and the cylinder 12 returns the additional scraper 9 to its original position.

When re-clogging the gap 8

the cycle repeats.

Thus, the additional scraper automatically cleans the gap and the main scraper, which significantly increases the reliability of the slave / I- / 1

DEVICE FOR CLEANING THE CONVEYOR BELT by ed. No. 1093653, it is important that, in order to increase the reliability of the device by automatically cleaning the gap for the exhaust air from the viscous material transported by the conveyor, it is equipped with an additional scraper installed in the cavity housing with the possibility of reciprocating movement by means of a cylinder along the main scraper and the location in the gap between the groove wall and the main scraper, while the additional scraper has an air bypass channel, and the cylinder is mounted on the housing and is single with a source of compressed air through a pneumatic valve, which has a pressure sensor 59 in communication with the cavity of the housing.
