RU1802161C - Belt conveyor discharge cart dedusting apparatus - Google Patents

Abstract

Usage: dust removal in the flour, elevator, coal, and other industries associated with the movement of bulk materials. SUMMARY OF THE INVENTION: the device consists of a drop box with gravity drains, a shuttle pipe with aprons, a slotted duct / connected to a suction fan, an additional fan, a chute and a brush. The brush kinematically communicates with the loading drum and cleans the idle branch. Dust is poured into the confuser and fed to an additional fan, and then to the slotted duct. From gravity flow and a discharge box, dusty air enters through the shuttle pipe into the slotted pipe and is sucked off by the main fan. 4 ill.

Description

The invention relates to the equipment of a conveyor belt, can be used for dusting in milling, grain, coal and other industries related to the transfer of bulk materials.

An object of the invention is to increase the dedusting efficiency of the unloader.

rjfa FIG. 1-4 shows the proposed device,

The device consists of an unloading cart (11 with a dropping box 2 and two gravity drains 3, inside which air channels 4 pass. Channels 4 are closed at the top of the gravity drains 3 and pass through a diffuser 5 into an air duct 6 connected to the air duct 7. One the end of the duct 7 ends with a confuor 8 with a brush 9 for cleaning the idle branch of the conveyor 10. A confuser 8 from the opposite of the brush 9

the side is connected to the pallet 11 of the unloading carriage 1, equipped with sides and together with the idle conveyor branch 10 forming a kind of air channel. The other end of the duct 7, after being connected to the duct 6, is connected to the suction port of the fan 12 mounted on the pad 13. To the outlet of the fan 12 is connected a discharge duct 14 with a shuttle 1.5 that enters the slotted pipe 16c with aprons 17. Brush 9 receives rotational motion from drum 18.

The device operates as follows. When the unloading trolley 1 stops at the place of unloading of the product, a conveyor is turned on, feeding this product from the silo. At the same time, the fan 12 and the fan that creates a vacuum in the slotted tube 16 are turned on. The brush 9 through the front of the unloading drum 18

receives rotational motion and at the same time removes dust from the idle branch 10 of the conveyor. Dust is poured into the confuser 8 and with air through the air duct 7 enters the fan 12, air duct 14 and the shuttle 15 into the slit pipe 16, from where it enters the dust separator through the slit pipe fan. From gravity flows 3 and discharge box 2, dusty air enters through air ducts 4, a diffuser 5, air duct 6, air duct 7 and further also to the dust collector through fan 12, air duct 14, shuttle 15, slotted inlet duct and slotted pipe fan.

The use of the proposed device in slit suction networks will significantly reduce the amount of dust polluting the air of the working area of the conveyor belt and outside the unloading trolley. The working conditions are improved and the service life of the mechanisms is extended.

Claims (1)

SUMMARY OF THE INVENTION A device for removing dust from an unloading carriage of a conveyor belt, including a dropping box with gravity pipes, a shuttle pipe having an apron and in communication with slot air fifty 5 water connected to a suction fan, characterized in that, in order to increase dust removal efficiency, it is equipped with an additional fan, two air ducts and a suction pipe located under the idle branch of the conveyor belt, trough and brush, while the brush is kinematically connected to the loading drum the conveyor belt and is installed with the possibility of contact with the idle branch, and the gutter is installed along the idle branch and placed between the discharge box and the brush, the air ducts are in communication with gravity ducts trolley and the inlet pipe of the additional fan, the inlet part of the suction pipe is made in the form of a cbnfuser and placed under the brush, the outlet part is in communication with the inlet pipe of the additional fan, and the outlet pipe of the additional fan is in communication with the inlet of the shuttle pipe, while the ratio between the width of the gutter and the width of the conveyor belt is 1.15-1.2, and the ratio of the gap between the idle branch and the bottom of the groove to the distance from the side of the groove to the edge of the conveyor belt is 0.7-0.9.
