Description

one

The invention relates to tubing pneumatic conveying, in particular to installations for the pneumatic transportation of piece goods, and can be used to transport piece goods in containers, for example, in metallurgical problems for transporting process samples from furnaces to an analytical laboratory.

The purpose of the invention is to increase plant productivity.

Fig. 1 schematically shows the installation of mail, a general view (the sending station is not shown), Fig. 2 shows view A in Fig. 1, and Fig. 3 shows node 1 in Fig. 1.

The installation contains a transport pipeline 1, located at an angle l (figure 2) to the horizon and at the end of which there is a brake chamber 2 with an end discharge opening, closed by a locking body. Brake

2 is located at an acute angle to the horizontal plane.

The locking member is made in the form of an L-shaped cross section of a tray located at an acute angle (Fig. 1) to the horizontal axis. One of the walls 3 of the tray is perpendicular to the longitudinal axis of the brake chamber 2, and the other wall 4 has an adjacent wall

3zone longitudinal slot 5 for the passage of piece goods 6, transported by pipeline 1 in the container 7.

The tray is mounted with the possibility of its drive 8 relative to the brake chamber 2 in the guides 9 arranged parallel to the longitudinal axis of the brake chamber 2 and fixed on it by means of a ring 10 mounted for free rotation on the brake chamber 2. By rotating the ring 10 around the brake Camera 2 selects the optimum angle L, then the ring is fixed.

In the initial position, the wall 3 of the tray tightly blocks the discharge opening of the brake chamber 2.

A feed bin 11 is attached to the tray in such a way that its passage opening is a continuation of slot 5. Sensor 12 is installed on line 1, preferably 202980, 2

but magnetodynamic acting on the executive circuit (not shown) of the drive 8.

In the side wall of each container 7, a window 13 is made in the forward direction of its movement, with one sectioning plane of the window passing through the longitudinal axis of the container, the second along the inner surface of the bottom of the container, and a third perpendicular to the longitudinal axis of the container in such a way that the height (fig. 3) of the opening is greater than the height of the load so that the load freely slides 15 the shaft under its own weight from the inclined container 7.

In some cases it is necessary from a technological point of view that the load is uniformly oriented by the same side relative to the addressee, for example, the receiver of the processing machine.

For this purpose, a partition 14 is made in the container, parallel to its

The bottom 25 and the distance from it at the distance I (Fig. 3), which excludes the reversal of the load in the container, and to the exit of the guide bunker 11 are pivotally attached at one end to the free rotation of the spout 3 (the directions of its rotation are shown in FIG. .2 arc arrows) entering the free end into the feeder tray or receiver 16 of the addressee. At the same time, the width of the guide bunker and the chute are chosen to exclude the possibility of axial rotation of the load in them.

Angle 0 is selected preferably in the range of 43-60, so that Kai with of "43 friction makes it difficult to slip out

container from the pipeline, and when

 rotation of the container on the tray is impaired.

The angle of ft is chosen preferably within 10 ° C, since at 10 ° the container does not scatter due to friction on the tray, and when the container slides down, it practically does not rotate.

 The installation operates (an example of its use for delivering technological samples in the form of a disk from metallurgical furnaces to an analytical laboratory) as follows. 55 JJ moment of passage of the container 7 through the pipeline 1 by the sensor 12, the latter acts on the actuator actuator circuit 8 of the tray. The actuator 8 moves down along the guides 9 the tray together with the hopper 11 and the chute 15. The container 7 is lowered out of the pipeline under its own weight along with the tray and, sliding to its wall 3, begins to rotate down the tray (shown by a figured arrow figure 1).

The load (sample 6) at the same time, under its own weight, slips out of the container through the window 13 in it and

enters through the slot 5 into the feed bin 11, and from there through the movable channel 15 (shown by arrows in FIGS. 1 and 2) into the feeder tray or into

receiver 16 processing machine (not shown).

After that, the tray with the help of the control circuit and the actuator 8 returns to its original position and

pneumatic mail is ready for operation again.
