Abstract

THE DEVICE FOR THE DAY OF DOWNLOADING A MATERILLE IN THE PNEUMOTRANSDORT PIPELINE containing receiving chambers with upper loading windows, hermetic valves and pressure relief valves, branch pipes to connect the chambers with the transport pipeline and the air-flow pipes connected to the chambers and the air flow, and the flow of the device, the plan will go to the surface of the project, as well. In order to increase the reliability of operation, the branch pipes are connected to the chambers in its lower part, the air supply pipelines are installed inside each chamber along with the above-mentioned branch pipes the movement from the drive along their axis, and hermetic closures consist of annular elastic stops having a longitudinal section of the shape of trapeziums, facing large bases towards the inner wall of the chamber and mounted one above the other on it, and attached to the air support pipe elastic rests of rigid guides: having the shape of a cone facing down.

Description

The invention relates to pipeline transport, namely, a device for loading material into a pneumatic transport pipeline.

A device is known for loading 5 materials into a pneumatic transport pipeline, which contains chambers with upper loading windows, hermetic closures and pressure relief valves, nozzles for connecting 10 chambers with a transport pipeline, and air supply lines communicating with the chambers and the transport pipeline. his work because of the complexity of the design and control of technological processes for the introduction of bulk material in the pipe transport pipeline 20

The purpose of the invention is to increase the reliability of the device.

This goal is achieved by the fact that in a device for: 1 ruzkn material in a pneumatic transport pipeline, containing receiving chambers with top loading windows, sealed shutters and pressure relief valves, nozzles for connecting chambers with a transport pipeline and communicating with chambers and by the transport pipeline, the air supplying the pipeline, the branch pipes are connected to the chambers in its lower part, the air supply pipelines are installed inside each chamber coaxially with the mentioned branch pipes, which can be moved and from the drive along their axis, and hermetic closures cocToJfiT of annular elastic stops, having in the longitudinal. The Q section is the shape of a trapezoid with large bases facing the inner wall of the chamber and mounted one above the other on it, and fixed on the air supply pipe and aligned with rigid supports of rigid guides, having the shape of a cone with the base facing down.

The drawing shows the device, 50 longitudinal section.

The device for loading material contains receiving cylindrical chambers 1 and 2 with loading windows 3. Each of the chambers goes into a cone, 55 mated with nozzles 4 for connecting chambers 1 and 2 to a transport pipeline 5.

Inside each chamber, along one axis with nozzle 4, air supply pipes 6 are installed with the possibility of vertical forced mixing, for example, a pneumatic cylinder 7 fixed to a rod 8 which is pivotally connected to the rocker arm 9, pivotally connected to the middle part with chambers 1 and 2 of the device.

Guides 10 are rigidly mounted on the outer surface of the air supply pipelines 6 at the same distance from each other, and the inner surface of the chambers 1 and 2 are provided along the perimeter by guides 11 made of elastic material, installed in height with an offset by the stroke of the air supply pipe, the angles of inclination of the mating surfaces of the guides are equal and form an angle with the vertical that is greater than the angle of repose of the bulk material. The chambers are also provided with pressure relief valves 12.

The device works as follows.

Camera device alternately loads the transport pipeline. Which operates continuously. During the unloading period of chamber 2, chamber 1 is loaded with bulk material, which through loading windows 3 and the space between guides 10 and 11 completely fills chamber 1. During this period, a signal is sent from the automation system to the pneumatic cylinder 7, | which, by means of the rod 8 and the rocker arms 9, moves the air supply pipe 6 of chamber 1 upwards, and chamber 2 moves downward, where pressure of compressed air is relieved by valve 12, the space between air supply 6 and transport pipeline 5 closes, and then the process of loading the chamber with bulk material takes place. In chamber 1, during this period, it is sealed by pressing guides 10 and 11 and unloading the material into transport pipeline 5 due to gravity forces and compressed air jets. After unloading chamber 1 and loading chamber 2, a signal is applied to the pneumatic cylinder 7, which returns the air supply pipelines to their original position, and the whole process repeats.
