Description

The device relates to pipeline transport, namely to lifting devices with vertical and inclined from the vertical pipelines with an increased concentration of bulk materials in the carrier medium.

Known devices for lifting bulk materials containing vertical and inclined from the vertical transport pipeline and the transverse perforated inserts installed therein are dispersed (Patent RU No. 2194661, December 20, 2002, Patent RU No. 138223, 03/10/2014).

In these devices, the absence of flange connections on the pipeline makes it difficult to rearrange the transverse perforated inserts in a given height position, depending on its technical and economic parameters.

A device for lifting bulk materials is also known, comprising a transport pipeline onto which vertical and inclined sections of pipelines are mounted by means of flanges, inside of which transverse perforated inserts are dispersed (Patent RU No. 2294886, 03/10/2007).

This device also complicates the oriented reinstallation of transverse perforated inserts in a predetermined height position depending on the technical and economic parameters of the elevator, which leads to a decrease in its reliability and an increase in energy consumption.

The objective of the proposed device is to ensure the creation of readjustment, the reliability of the lift and reduce the consumption of energy by creating the specified design parameters of the device for lifting bulk materials.

This object is achieved by the fact that in the device for lifting bulk materials containing a transport pipeline and through flanges mounted vertical and inclined from the vertical pipe segments, inside of which transverse perforated inserts are dispersed, transverse perforated inserts are dispersed mounted on the longitudinal elements of the frames, which are located in the inner the cavities of the mentioned sections of the pipeline, while the frames are equipped with transverse elements for closing them Lenia in the flanges of the pipeline.

In FIG. 1 schematically shows the proposed device; in FIG. 2 is an embodiment of inserts; in FIG. 3 - node I in FIG. 2 and view A in an upright position; in FIG. 4 - frame assembly with longitudinal elements and transverse perforated inserts in a vertical position.

The device (Fig. 1) for lifting bulk materials contains a mixing chamber 1 with a vertical transport pipe 2. At the bottom of the mixing chamber, there are pipes 3 for supplying compressed air and a porous gas distribution 4. The transport pipe 2 contains flanges 5 and transverse inserts 6 in the form grids or nets. The feeding part 7 of the mixing chamber 1 is located above the inlet pipe of the transport pipe 2. The vertical pipe 2 is equipped with segments 8 of the pipeline. On the vertical and inclined sections of the pipeline 8 there are transverse inserts 9 in the form of gratings (Fig. 2), which are mounted on the frames 10. The frames 10 are inserted into the internal cavities of the vertical and inclined pipe sections of the pipeline. These frames consist of longitudinal elements (rods) 11, on which the transverse perforated inserts 9 are dispersed. The frames 10 are provided with transverse elements 12 for their fastening in the flanges 5 of the inclined sections of the pipeline 8.

The bulk material from the feeding part 7 is continuously fed into the mixing chamber 1. The carrier medium is supplied through the porous partition 4 under a layer of material. Aerated material with a high concentration is fed into the pipeline 2 through its inlet pipe. Due to the pressure drop, the material moves through the pipeline in a braked state by creating additional resistances in the form of transverse inserts 9 with holes installed dispersed over the height of the pipeline with a certain step. Particles of material flow sequentially through the holes of the transverse inserts 9 under the influence of a pressure differential, rising through the pipeline. By means of the transverse inserts 9, the material flow is aligned over the entire cross section of the pipeline.

To ensure a fixed position of the transverse inserts in the pipeline in height, the frame 9 is designed. Transverse inserts are mounted on this frame. This device simplifies the oriented installation of transverse perforated inserts, which leads to an increase in the reliability of the elevator and a decrease in energy consumption.

To change the distance between the transverse inserts after disconnecting the flange connection, the entire frame is removed from the pipeline and after reinstalling the transverse inserts is reinserted into the pipeline.
