Description

(54) MIXER OF BULK MATERIALS AND VISCOUS LIQUIDS

I

The invention relates to rotary mixers in a stationary tank and can be used to dislodge bulk materials and viscous liquids.

A well-known mixer of bulk materials and viscous liquids, consisting of a body, inside of which two concentrically mounted spirals with the opposite direction of winding 1 are installed.

Closest to the invention is a continuous mixer for displacing bulk materials and viscous liquids, consisting of a body within which two spirals of the same pitch and direction of winding are concentrically mounted. The spirals are interconnected by transverse elements, which, to prevent twisting, are made rigid and rigidly connected to them 2.

A disadvantage of the known mixers is the complexity of its manufacture, caused by the need to ensure the rigidity of the connection of the transverse elements with the spirals. It also requires increasing

thickness of the spirals, which reduces their flexibility.

The purpose of the invention is to simplify the manufacturing technology of the mixer and expand its functionality by increasing the flexibility of the spirals.

This goal is achieved by the fact that in the mixer, which contains two spirals of the same strap and direction of winding placed in the housing, connected by transverse elements, these transverse elements are installed with the possibility of angular movement relative to spirals.

In addition, the transverse elements can be made flexible in the form of threads, wire or chain, and in the latter case, the middle chain link can be made in the form of a rigid rod.

FIG. 1 shows a schematic diagram of the mixer; in fig. 2 - a unit for connecting spirals with transverse elements in the form of a chain, the middle link of which is made in the form of a rigid rod.

Claims (2)

The mixer consists of a housing 1, which can be made flexible, spirals 2 and 3, and transverse elements 4. Transverse elements 4 are made in the form of threads or wires and connected, with spirals 2 and 3, by gluing, welding or in some other way. The transverse elements 4 can also be made in the form of a chain 5, the middle link of which is made in the form of a rigid rod. The end links of the adjacent chains 5 are separated from each other by sleeves 6 and 2 and spirals 2. The spirals 2 and 3 may be of equal or different winding diameter, and the transverse elements 4 may lie along the forming cylindrical surface of the winding or be placed under the crown of the forming elements. The mixer works as follows. The material to be mixed is fed from one end of the housing 1, and as the coils 2 and 3 rotate, the material is transported and simultaneously mixed. The transverse elements 4, including those made in the form of a chain 5 with a rigid rod as its middle link, contribute to the movement and mixing of the material. The finished mixture is obtained at the other end of housing 1. Spirals 2 and 3 can be connected by transverse elements 4 - threads, wire or winding chains during or after winding. After the connection of the spirals 2 and 3 by the transverse elements 4, they are displaced to the contact (i.e., to the position when they are lying on the same screw surface) and rotated relative to each other by an angle ensuring the tension of the transverse elements 4. The proposed mixer is simple to manufacture because instead of rigid fastening of the transverse elements 4, a simple connection of spirals 2 and 3 with a string, wire or chain is used. This makes it possible to reduce the thickness of the spirals 2 and 3, i.e., to increase their flexibility. In this case, it becomes possible to transport and simultaneously move the material as it moves along a curved path, which expands the functionality of the mixer. Claim 1. Mixer of bulk materials and viscous liquids containing two spirals of the same pitch and direction of winding placed in the housing, connected by transverse elements, characterized in that, in order to simplify manufacture and extend the functionality by increasing the flexibility of the spirals, transverse elements are installed with the possibility of angular movement relative to the spirals. 2. A mixer according to claim 1, characterized in that the transverse elements are made flexible. Sources of information taken into account during the examination 1.
