Description

(54) MIXER

one

The device relates to devices for mixing materials and can be used in the chemical, petrochemical and other industries.

The known design is mixing, its devices consisting of a combination of high-speed and low-speed agitators fixed on coaxial shafts, high-speed and low-speed respectively. Each of the shafts receives rotation from its drive 1.

A mixer is known in which a small-diameter blade is fixed on the drive shaft, and a large-diameter blade is mounted in a bearing rotating in a stopper, which is connected to the bottom of the tank where mixing takes place. When lowering the cam drive shaft, mounted on the front end of the shaft, it engages with key grooves located in the hub of the blade of a large diameter, as a result of which this blade begins to rotate 1, 2.

However, the known technical solutions for drying are a number of drawbacks: the inability to control the blending mode with simple

means, installing a double shaft, a complex sealing system, low reliability and complexity of operation.

The closest to the invention to the technical essence is a mixer consisting of a combination of a high-speed and low-speed mechchalk, mounted on coaxial shafts, high-speed and low-speed, respectively. There is a seal for low-speed and high-speed shafts. The balls rotate in opposite directions from the actuator consisting of a motor and a gear I.

The disadvantage of this design is that the mixing mode cannot be adjusted without complicating the design of the device or without the use of a gearbox. The reliability of the device is low as a result of the use of a double shaft and a complex sealing system, in the case of the use of a fluid coupling due to the harsh operating conditions of the bearing. Repair of these units is difficult and time consuming. All this greatly complicates the operation of the device.

The aim of the invention is to simplify the construction and increase the reliability of the .voiuHBaioinero device with the possibility of ii.uiiMioio) egu: 1 of the mixing mode. The goal is achieved by the fact that the low-speed mesh is equipped with a head made in 1511 of the torus, rigidly fixed in its upper part, and installed coaxially with the corlivcy. The hoverhead has the ability to move vertically depending on the level 1; I am the medium under test, thereby changing the clearance in the fluid coupling, and hence cKopocTi, bp; it1 is a low-speed megawalka.

Since the ps / nlaws are on the surface and there is a constant. |) food, then a change in its level in arHia;) athe, carried out by known methods, causes the vertical movement of the elec .4Ta and, consequently, the low-speed agitator connected to it, which in turn leads to a change in the gap in the 1H1 coupling, since the number of coupling attached to .Junast m. slow. mixer, and before torque, resulting in the speed of the low speed mixer is measured. The proposed design of the mixer, in comparison with the prototype, has the following advantages: the introduction of a new structural element made it possible to reject the use of a double shaft, a compaction system and iodine 111n-1k for a low-speed agitator, which increases the reliability of the device and is umen1) It saves time () time and funds for its repair; the ability to regulate the speed of a low-speed variable; a simple means.
