In China market, corrugated sidewall belt conveyor is a new type of sidewall belt conveyor, because the machine has the following characteristics: large conveying angle (0° ~90° ), high lifting height; low energy consumption, simple structure, low maintenance costs; has been widely used in many industries, but because the belt has a three-dimensional shape belt composed of base belt corrugated type flexible baffle and cross partition, far more than the ordinary flat belt carrying material surface, thus bringing It is more complicated to clean the residual material attached to the belt after discharging than the conventional flat belt. This article introduces the cleaning method of the sidewall belt conveyor type at home and abroad.
The cleaning method is different from that of ordinary sidewall belt conveyor as we can understand from the above diagram: The corrugated belt is a three-dimensional shaped belt composed of base belt + corrugated flexible edge + cross partition, and as we can see from the above diagram, the materials are in contact with the base belt, corrugated flexible edge and cross partition, and there are many surfaces for carrying materials. After the belt is discharged, the complexity of the cleaning method to clean the residual material attached to the belt is more complicated than the most common scraper type cleaning method used for ordinary flat belts.
The following are the domestic and foreign cleaning methods of corrugated edge banding:
Belt tapper
The tape tapper is a simple and versatile cleaning method, which is ideal if the material being conveyed is dry.
Active tapper
(1) The tape beater should run at 300 to 500 revolutions per minute, generally using a v-belt drive with a separate motor;
(2) The beater should only press the tape down 6 mm to 8 mm; if more downward pressure is required, an auxiliary cleaning device should be added;
(3) The beater should be arranged as close as possible to the head drum;
(4) Shock-absorbing rollers must be used, mounted under the tape, and made The tape should be tensioned.
(5) The minimum diameter of the rollers is 60 mm;
(6) Double-row rolling ball bearings must be used;
(7) The tapping roller itself can rotate.
2) Passive tapper
2.2 Head roller water jet cleaning
If the pressure is suitable, it is both practical and ideal. Note:Only applied on small equipment, the application on small equipment with the height of 120mm and below of retaining edge, can use different type of nozzle to improve the pressure to achieve different cleaning force and cleaning effect.
2.3 Head roller air knife sweeper
If the pressure is sufficient, the effect is good. Three nozzles must be installed, aligned with the middle part of the contact between the base of each cross partition and the baffle, which is more practical on small equipment with baffle height 120mm and below. An air compressor is required.
2.4 Collector tray under the return section
If the tapper is used and the material has less moisture, the return branch of the conveyor can be closed and a dumping device and a collecting tray can be set up in the lower variable angle section, at the position where the conveyor belt changes from the inclined section to the horizontal section. The material of the collecting tray can be sent to the dumpers by the chute. If the inclination angle of the conveyor is less than 60°, the return tray can be lined with ultra-high polymer material to prevent the returned material from piling up in the tray. At this point, the return material can be manually fed back onto the conveyor's carrying section. This method cannot be used
Sidewall belt conveyor can not be used for viscous material, because the return material is too much and will be piled up in the chute.
