Abstract

Mixing unit, comprising an obliquely mounted heated mixing chamber having devices for loading the initial components and unloading the finished product, as well as a mixer located coaxially with the chamber, made in the form of a shaft connected to a rotation drive, on which hubs with blades and screw elements are rigidly fixed, providing mixing and translational motion of the material loaded into the chamber while heating it, characterized in that the stirrer blades are helical about its shaft, and the elements of the screw are located in the end part of the shaft of the mixer adjacent to the device for unloading the finished product, and the direction of winding screw-like blades and elements of the screw provides the possibility of mixing and translational movement of the processed material in the direction of unloading and unloading the finished product, and the device for loading the initial components are made in the form of a hinged lid mounted on the housing of the mixing chamber and having nozzles for withdrawing water vapor from the working space of the chamber a.

Description

The direction of rotation of the annular element allows the mass to move in the opposite direction to that in which the mass is moved by the screw. An annular element consists of two rings, a hub, two wide and four narrow blades. All blades are rigidly connected to the rings and the hub and rotated 30–40 about the axis. The screw is rigidly fixed on top of the rings on the shaft.

The described installation has the following disadvantages:

1. The design of the auger blades and the mixer provides for double movement of the processed material in the volume of the mixing chamber - first in the direction opposite to the discharge direction, and then to the discharge chamber.

2. The device for loading the initial components into the mixing chamber is made in the form of a highly located hopper, which creates inconveniences in operation and complicates the design of the installation.

3. The design of the installation does not provide a device for the output from the working space of the mixing chamber of water vapor generated during the heating of the processed material.

The task to which the proposed technical solution is aimed is to simplify the design of the installation, increase its productivity, while improving the quality of the resulting hot mixture, ensuring ease of use.

To solve this problem, it is proposed that the mixer blades be screw-shaped, and the screw elements should be located in the end part of the mixer shaft adjacent to the device for unloading the finished product, while the direction of winding of the screw-phase blades and screw elements was performed in such a way that they provided the possibility of churning and translational

the movement of the material to be processed in only one alphabet in the direction of unloading, and also the unloading of the finished product from the mixing chamber was carried out.

In the proposed installation, the device for loading the initial components is made in the form of an open 1 flap pivotally mounted on the housing of the mixing chamber and equipped with nozzles for withdrawing water from the working space of the mixing chamber.

The proposed technical solution is illustrated by graphic material, which schematically shows the design of the proposed installation.

Presented graphic materials show:

FIG. 1 - general view of the installation;

FIG. 2 - longitudinal section of the installation;

FIG. 3 is a cross-sectional view of the apparatus along AA (FIG. 2). The following notation is accepted:

1 - wheel; 2 - trolley frame; 3 - articulated truck handle; 4 - electric motor; 5 - gear; 6 - thrust bearing of the mixer shaft; 7 - pivotally mounted folding hinge; 8 - mixer blades; 9 - mixer shaft; 10 - element of the screw; 11 - installation casing; 12 - mixing chamber; 13 - electric heating elements; 14 - nozzles for water inlet; 15 - damper handle.

The installation is as follows.

Discontinued; for its repair of the roof section, a worn out ruberoid coating, crushed to the required size, with the lid 7 folded down (FIG. 2), is loaded into the working chamber 12 (FIG. 3X preheated to operating temperature using electric heating elements 13. this outlet 18 (Fig. 1) should be closed with the help of the handle 15 (Fig. 2) and the shutter 17 (Fig.) After loading the material into the heated chamber 12, the cover 7 is closed and the installation for heating the material is turned on

to a plastic state (it is determined by the readings of temperature sensors mounted in the installation case - not shown in Fig.).

After warming up the ruberoid mass to a viscous-plastic state, the drive of rotation of the shaft of the mixer 9 is turned on (the drive contains an electric motor 4 and a gearbox 5 - see Fig. 2).

In this case, the blades 8 fixed on the shaft begin to mix and move the ruberoid mass along the axis of the mixer shaft towards the discharge side, and this mass movement occurs while it is heated. The resulting water vapor is removed into the cavity of the hinged lid 7 and discharged outside the installation through the nozzles 14 (Fig. 1).

After reaching the desired ductility, toughness and consistency of the material being processed, the handle 15 is turned in any direction shown in FIG. 1 arrow, while opening with the help of the shutter 17 the outlet 18.

Using blades 8 mounted screwwise relative to the shaft of the mixer and the element of the screw 10 (Fig.2.3), as well as under the action of gravity acting on the hot ruberoid mass (since the installation is located at an angle to the horizontal) it, through the outlet the chute 16 (Fig. 2) is unloaded onto the primed section of the roof to be repaired, where it is laid with a layer of the required thickness and Efikag.

Due to the features listed above, the proposed technical solution, in comparison with that adopted for the prototype, provides simplification of the installation design, increase of its productivity (as TOIQ.KO moves the processed material in one direction - towards the discharge side), convenience in work (folding krnpka is not located high, but is "at hand).

In addition, it is possible to remove the water produced during operation outside the installation.
