(54) DEVICE FOR SUBMITTING DISPERSABLE

MATERIALS FROM ZONE WITH LESS PRESSURE INTO ZONE WITH LARGE PRESSURE

The invention relates to the transport of bulk materials and can be used in various industries to supply material from a zone with less; pressure in an area with high pressure.

A device for supplying bulk materials to a transport pipeline is known, which includes a vibrating device connected to a receiving hopper and a transport pipeline. However, this device has a low tightness and productivity of the device, since the vibrating material combines into a spindle shape . center, in the lower part, forming a free space where gas is directed from the pipeline and is pushed out during vibration. .. It is also known a device for transferring bulk material from one zone to another, has a pressure different from the first one. with the possibility of changing and fixing its position relative to the longitudinal axis of the pipe 1 /.

But such a device is not reliable enough in operation due to the non-high tightness of the vibro-feeder, and its performance

0 low

The purpose of the invention is to improve the performance and reliability of the device in operation.

This goal is achieved by

5 that on the inner walls of the pipe in its upper part there is an annular protrusion of a streamlined shape, and the discharge body is made in the form of a glass with openings for the release of material

0 rial and is provided with a spring-loaded cone-shaped valve installed inside.

The drawing shows a general view of the dispersed-feed device.

5 materials from the zone with lower pressure to the zone with greater pressure.

The device consists of a hopper 1 / into which the bulk material is fed, the upper layer, the shutter 2

The glass is installed in such a way / that it is possible to change its height, fixed. in several possible positions on the pipe 8, respectively, changing the size of the window 13 to unload the material and the height of the vibrating lr material. Inside the glass a 12.

The cone is installed, the valve is 147 uo torsh shygu edd ytzhet with adjustable spring 15.

The device works as follows. . ; -; -.

- The heated wet material from the hopper 1 enters the upper layer valve 2, and then c. perforated pipe 5, from where it enters the region of the akuma in the perforated pipe

Above the protrusion 9, freedoms are formed - no space for the flow flow paspawa, which is filled with a new portion of the material from the bunker 1 under the action of pressure difference; st1 , acquires the highest PORST, after which the vibrating feeder is given, up, up, and the material, by inertia, moving downward, npeoflprteSaeT 6, is the opposite of the pressure differential of the medium.

the adhesion of particles and the pressure of the spring and pours out through the windows 13 to the top. The action of the protrusion 9 when moving the vibrating feeder up is similar to its action when moving down. The column of the material, which is constantly S pipe 8 of the vibrator, acts as a lower shutter gate, preventing air from penetrating the atmosphere into the housing 4. To reduce air filtration through the material layer — below the layer shutter, there is a cone valve 14, which with adjustable spring 15 51 py 5th ety yy: nye lOi material or completely closes the pipe 8.

The differential pressure measured by the vibrating feeder is directly dependent on the acceleration of the vibration, determined by the amplitude and frequency of the vibration, and the height of the vibrated pillar of the material (layer gate). With a change in pressure drop or physical properties of the material (specific gravity, dispersion, humidity, stickiness), it is necessary to change the height of the vibrated column of material and the section of windows for unloading the material. With this purpose, the tube 12 is installed with the possibility of axial movement. In the working position, the tube 8 and the cup 12 are rigidly fastened, for example, with screws.
