Description

The invention relates to pneumatic conveying, in particular, to a device for inserting bulk materials into a horizontal pneumatic installation pipeline, and can be used for granular and powder materials, for example, in preparatory workshops of tire factories.

A device for introducing bulk materials into a horizontal pipeline of a pneumatic conveying installation is known, which includes a charging nozzle connected to the upper part of the pipeline and located inside the pipeline at the point where the material is introduced into it, metering a horizontal platform that is mounted on supports 1.

The disadvantage of such a device is that part of the material pulls out a horizontal platform and remains lying on it in bulk. When the cross section of the pipeline is narrowed at the point where the material is introduced into it, the conditions for raising and dragging other portions of materials into the flow deteriorate. As a result, in practice, it is not uncommon for a pipeline to become clogged with material and to stop transportation.

It is also known a device for inserting bulk materials into a horizontal pneumatic line piping, comprising a nozzle installed along the axis of a horizontal pipeline, located inside the nozzle and a pad hinged to it at one end and mounted above the loading platform.

10 branch pipe 2.

A disadvantage of the known device is the accumulation of bulk products at the site, for example, when coarse-grained materials (rubber granules and crushed rubber) are introduced into the pipeline. For such materials, the site site does not give the desired positive effect.

The purpose of the invention is to improve the reliability of operation of a pneumatic installation by using the elastic properties of the particles of the material.

The goal is achieved by the fact that the device is equipped with a vibrator,

25 includes a horizontal vibrating table, connected to the free front end of the platform, and an electric motor mounted on it, on the shaft of which disks are eccentrically fixed. FIG. 1 shows the device section; in fig. 2 is a section A-A in FIG. 1; on fig.Z - section bb in figure 1; in fig. 4 — node 1 in FIG. 1 The device consists of a loading nozzle 1 connected to the patron 2 through the hopper 3. Inside the nozzle 2 is located at an angle of 5 - 10 ° to the horizon. The platform is attached to the upper wall of the nozzle 2 by means of a suspension 5 and a nut b rotatably hinge 7. In the lower part of the nozzle, the platform 4 rests on the rod 8, which is connected to the vibrating table 9, to ensure tightness, the rod 8 is connected to the pipe 2 by means of a sleeve 10. The vibrating table is fixed on two or more springs 11. vibro table the bolts fasten an electric motor 12 of constant or alternating current on the shaft 13 of which is eccentrically attached to the disks 14. The housing 15 is designed to enter the transported mixture into the pipeline 16. The device operates as follows. The bulk material under its own weight falls from the pipe 1 to the platform 4, which is subject to vibration. The material is in motion at the site, the bay nods from it and is weighed by air flow. Part of it crawls around pad 4 and also enters the air stream. The vibration of the platform 4 is transmitted through the rod 8 and the vibrating table 9 from the electric motor 12. The proposed device provides the best conditions for introducing material into the gas flow and improves the reliability of the pneumatic installation, firstly, due to the vibration of the horizontal platform, the particles of the material falling on it in constant movements relative to each other, which facilitates the penetration of air into the gaps between them and, consequently, facilitates the removal of material from the site, and secondly, the presence of a slight slope at the site leads to slipping vibrating layer in the gas stream (which can not be achieved using a known device). The reliability of the pneumatic installation in the proposed device is ensured by the fact that due to the continuous selection of the material falling on the platform by the gas stream, no accumulation of material occurs on the platform, and, as a result, the restriction of the flow area and clogging it with the conveyed material. . The device for inserting snap materials into a horizontal pneumatic line, containing a pipe installed along the axis of a horizontal pipe, located inside the pipe and a pad hinged to it at one end. And a loading pipe mounted above the site, in order to improve the reliability of the pneumatic air suspension. due to the use of the elastic properties of the particles of the material, it is equipped with a vibrator, including a horizontal vibrating table connected to one front end of the platform and an electric motor mounted on it, on the shaft of which the disks are eccentrically fixed. , Sources of information taken into account during the examination 1.
