Description

The invention relates to construction and can also be used in the chemical, food and other sectors of the national economy.

Known mixer, in which the device for unloading is made in the form of a tray ij,

The disadvantage of this mixer is the difficulty of unloading the material and the difficulty in controlling the flow during unloading.

It is also known a device for unloading a mixture, comprising a discharge opening made in a housing with a shutter, a compression spring and a rotating tray, fixed to the housing by means of a hinge,

The prepared mixture enters the dispensing bin installed below the mixer. At the same time, after the distribution of the hopper is installed, the swiveling tray is placed in the working position, and before the hopper is raised, the swiveling tray is lifted up, set to the vertical position 2.

The disadvantage of this design is the need for a shutter moving in a vertical plane, since the rotation of the tray is caused by its interaction with the shutter.

Such a shutter is unreliable when unloading adhering mixtures. The particles of the mixture go into the grooves formed by the guides and, filling in, interfere with the free movement of the valve.

This necessitates the installation of hinged-sash valves in most mixers.

The aim of the invention is to increase the reliability and efficiency of the device.

This goal is achieved by the fact that a device for unloading a mixture containing a discharge opening in the body with a shutter, compression springs and a rotating tray fixed to the lower edge of the discharge opening and placed above the rotating tray parallel to it

20, a hinge is installed between the edge of the guide pan and the discharge opening, and the springs are placed between the trays.

25 transfer hopper; in FIG. 2, node 1 in FIG. 1 (unloading device); Fig. 3 shows a device for unloading when the bunker moves downwards; Figure 4 shows a device for unloading while moving.

30 bunker up.

The device comprises a housing 1, a stirrer 2, an actuator 3, a slide 4 and a razgueochny hole 5.

To the lower edge of the discharge opening 5, a guide tray 6 is rigidly fixed, containing the bottom 7 and beads 8

Below the guide chute b is mounted on a hinge 9 a swivel chute 1 containing the bottom 11 and sides 12. The bottom 11 of the swivel tray 10 and the bottom 7 of the guide chute 6 are parallel. The hinge 9 is installed between the edge of the tray 6 and the discharge opening 5, namely, it is offset by the value of a from the vertical plane 0 - and passing through the edge of the guide tray. The ends of the hinge 9 are mounted on a Reinh 13 bracket fixed to the housing 1. The tail part 14 of the bottom 11 is bent at a slight angle and rests on conical compression springs 15, which are rigidly fixed to the rear surface of the bottom 8 of the guide tray

The discharge hole 5 is blocked by a bolt 16, hinged to the housing 1.

The mixer works as follows.

 After the mixture is prepared, it is dispensed into the dispensing hopper 17, which is lowered by the Mounting Crane at the bottom 18, located below the mixer (Fig. 1).

When lowering the dispensing hopper 17, the bunker case pushes on. swivel tray 10, turning it around the hinge 9 (Fig. 3),

After the installation of the bunker 17 in the case of wet 18, the tray 10 comes out of contact with the bunker and returns to its initial position under the influence of the springs 15 (Fig. 2).

Thus, the tray 10 overlaps the booker (Fig. 1) and when the solution moves through the tray, the solution completely enters the bunker. The sides 8 and 12 exclude the spreading of the solution beyond the limits of the trays 6 and 10. When the hopper 17 is raised, the body of the latter turns up the rotary tray 10 (figure 4).

At the end of the lifting of the bunker (at the time of the end of the contact of the bunker with tray 10), tray 10 falls under its own weight, returning to its original position (Fig. 2). This is due to the fact that the spryner 9 is offset from the vertical flat, 0-0 bone, as a result, the tray 10 rises to an unstable inclined position (Fig. 4).

 The hopper loaded with the solution is raised by the erection crane to the workplaces of bricklayers, concrete workers; after the distribution of the solution (concrete) into the receiving tanks, the process is repeated.

The pre-mixed mixer provides control of the mixture flow when dispensing it, greatly enhancing the production culture.

The advantage of the displacer is also the possibility of using any type of valves in it, which significantly increases the reliability and efficiency of the process of unloading the mixture.
