Abstract

This invention relates to the transport of dust by gravity through pipelines. The purpose of the invention is to increase productivity. The method of transporting dust by gravity through pipelines consists in sucking air through the pipeline in the direction of transporting dust moving inside the pipeline under the action of gravity. Pulling air through the pipeline at a speed lower than the speed of soiling of the dust particles in its loading end reduces the resistance to the movement of dust particles and improves the transport performance. 1 il.

Description

one

The invention relates to the transportation of pulverized bulk materials by gravity and can be used in the elevator, milling and feed industry.

The purpose of the invention is to increase productivity.

The drawing shows the scheme of the method implementation, general view.

The proposed scheme includes a dust collector, such as a cyclone I, installed at a high altitude (30-60 m), into which the dust-air mixture enters through air duct 2. Purified air is emitted into the atmosphere through air duct 3 connected to nozzles to remove clean air from the cyclone 1 To the conical part 4 of the cyclone 1, in which the anti-suction cone is mounted, a pipeline 5 is connected. At the entrance to which is installed a branch pipe 6 with a collector 7 for air leaks. Pipelines 5 from under a number of cyclones are combined into one common pipeline 8 connected to the inlet of a dust separator 9, for example a filter. All pipelines 5 and 8 have an angle of inclination to the horizon greater than the external friction angle of the transformed dust and pipeline material.

Under the dust separator 9, a lock gate 10 is installed and the entire system is mounted on the dust collecting bin 11. A fan 13 is connected to the dust separator 9 through the air duct 12, which discharges purified air into the atmosphere through the air duct 14.

The method is carried out as follows: not only under the action of the weight, but also under the action of the movement. The air-dust mixture with the concentration of aerodynamic resistance forces, for example, 6-10 g / m gets pony, i.e., pneumatic transport is carried out;

air ducts of 2 c. cyclone I, installed-with requiring additional energy costs,

At an altitude of 30-60 m. Purified air. In this way, conditions are created for cyclone I through air ducts 3 to allow dust to move downward along the atmosphere. Delayed in the CEC pipeline under the action of the particle weight of dust 1 dust through the conical part 4 cycli. After connecting the streams of dust, the dvilon 1 enters the pipeline 5. Through the counting pipe 5, into one pipeline generated in the pipeline 5. pipe 8, it goes along with the fan 13, into the pipeline 5 Й1хх to the dust separator 9, installed , the place of its connection to the conical i, for example, at a height of 8 m. The discharge in the cyclone I part 4 through a pipe with a number of ducts 5 is created by the fan 13, the air is sucked in by the lecturer 7. When the blown-off fan 13 is connected to the dust separator 9 in the pipeline, the conduit 12. The exhaust air blowout 50 is discharged from the system to the horizon over the system, when the dust particles move down behind the outlet 14 connected to the output

Claims (1)

dust reducing their moving speed — Application of the proposed NSN method downwards. For the expense of. natural draft, 20 porting of dust through pipelines after the large length of dust collectors arising in pipeline 5 allows to provide poenas (heights), an air flow is created, that is, removal of trapped dust from under the upward movement and significantly increased; dust collectors, to prevent the dust from clogging the forces of the aerodynamic resistance to frush pipes and to increase the arbitrariness of the dust particles to such an extent that they are pre-25 D P ° P P and the gravitational forces exceed. In this case, the dust particles are either not transported down or rise, which may. The claims of the invention lead to blockage of the pipeline. In order to avoid this, at the entrance to the pipeline; the method of transporting dust is self-flowing; it is necessary to eliminate the air flow, 30; one through the pipeline which includes loading upwardly moving, which is achieved by dusting the upper end of the pipeline, recreating the vacuum in the pipeline 5, ventilating the dust through the pipeline from the upper killer 13, and ensuring that the end to the air velocity in the pipeline and the discharge of dust from the lower one is zero, or the air from the minimum pipe of the pipe, which is different from it, which, at a speed close to zero, moves 35; in order to increase productivity, through the pipeline downward. I, through the pipeline in the direction of transdivision, bring the ethn velocity to the values; porting, suck air from ; {) with a sponge not exceeding the soar velocity of dust particles in the upper end of the pipeline. it is impossible to exceed the soar speeds of dust particles, since in this case the transport of dust particles through pipelines ; porting sucks the air off ; {) with a sponge not exceeding the soar velocity of dust particles in the upper end of the pipeline.
