Description

The invention relates to the chemical industry and is intended for mixing viscous-plastic and bulk masses. The mixer is designed for mixing powder components in a liquid medium, as well as components that are suspensions and suspensions.

A device for producing a viscous-plastic mixture (patent for the invention of the Russian Federation No. 2566784), containing a cylindrical container for mixing liquid and dry bulk components, a mixer with holes and a device for rotation, a dry component supply device, a device for supplying liquid components and a device for outputting viscous - plastic mixture, the mixing container is made airtight and equipped with nozzles for components feeding devices and a nozzle for creating a vacuum in the mixing container, the mixer is installed on the inclined bottom of the mixing container cylinder with a single axis of rotation and is made in the form of a movable rotor with helical blades, and a fixed stator equipped with a perforated inner cylindrical container with an upper part in the form of an inverted truncated cone - a diffuser, moreover, the branch pipe of the dry components supply device is directed to the upper part of the internal cylindrical container, and the branch pipe of the liquid components supply device directed tangentially to its surface from the outside.

The disadvantage of this technical solution is the complexity of the process, namely the constant need to maintain a vacuum when preparing the mixture, that is, to ensure the tightness of the assembly, since when the equipment is depressurized, a mass will be obtained that differs from the required consistency. Also, one of the disadvantages of this solution is the complexity and laboriousness of manufacturing helical nozzles.

The objective of the invention is to create a mixer of powdered components in a liquid medium, as well as components that are suspensions and suspensions, in particular to obtain a positive active mass for the manufacture of electrodes of chemical current sources.

The technical result of the claimed invention is to improve the electrical and mechanical characteristics of the electrodes of chemical current sources made using a positive active mass obtained in the inventive mixer.

The specified technical result is achieved due to the fact that the mixer of the active mass contains a frame, which is a welded structure with plates, on the plates of which a rotary hydraulic apparatus is installed, consisting of a rotor and a stator with teeth, with a drive and a container for loading, interconnected by pipelines forming a closed a system for circulating the mixed components, as well as a container for filling the binder and a container for filling condensate or water, installed on separate racks and connected by a pipeline to the container for loading, equipped with taps, a pressure gauge and an electronic control component.

The invention is illustrated in the drawing. The positions in the drawing indicate:

1 - rotary hydraulic apparatus,

2 - bed,

3 - container for loading,

4 - container for filling condensate or water,

5 - container for pouring the binder component,

6, 7 - pipelines,

8, 9, 11 - taps,

10 - manometer.

The composition of the inventive mixer includes the following elements: a rotary hydraulic apparatus 1, a frame 2, a container for loading 3, a container for filling condensate or water 4, a container for filling the binder component 5, pipelines 6, 7, valves 8, 9, 11 and a pressure gauge 10 for pressure control in the device and an electronic control component, which includes a time switch, control buttons, a digital indicator and a signal lamp.

The mixer frame 2 is a welded structure with weight plates, on which a rotary hydraulic apparatus 1 is installed, consisting of a rotor and a stator with teeth and a drive (electric motor), and a container for loading 3. A container 5 is installed on a separate rack for pouring the binder component. On the other rack there is a container 4 for pouring condensate or water.

Loading container 3 is used to load powder components and mix them with the addition of liquid and binder components.

Tank 5 for pouring the binder component and tank 4 for pouring condensate or water are connected by a pipeline to the load tank 3. The rotary hydraulic apparatus 1 and the load tank 3 are interconnected by pipelines 6.7, forming a closed system for mixing circulation of the components.

When the rotor and stator rotate, the mixed medium from the constituent components breaks up into a large number of partial flows and flows with great acceleration through the rapidly changing numerous passages created by the teeth of the rotating rotor and stator. In this case, the mixed mass is exposed to intense pressure pulses, hydraulic shocks and cavitation effects.

The mixing cycle of the components is provided by the task on the time relay of the required time intervals from the moment the Start button is pressed. The "Start" button turns on the contactor. The contactor turns on the electric motor. Simultaneously with the contactor, the time relay starts and the digital indicator displays the time until the end of "Cycle 1". After a specified period of time, the bell is activated and the signal lamp lights up. The time relay automatically switches to 2nd channel indication. To continue the mixing cycle, press the "Cycle 2" button. Cycle 1 is the mixing of an aqueous solution and dry substances, and cycle 2 is mixing after pouring a fluoroplastic suspension into the solution of cycle 1. This starts the second channel of the time relay. The preferred time of cycle 1 is 6 minutes, the time of cycle 2 is 1 minute 30 seconds. At the end of the mixing cycles, the signal light turns on. After mixing is completed and the active mass is drained, the mixer is turned off with the Stop button. You can also stop mixing at any time by pressing the Stop button.

Thus, the use in the design of the inventive mixer of a rotor and a stator with teeth, as well as an electronic component that sets the required time mode of operation, makes it possible to obtain the necessary homogeneous consistency of the active mass with improved mechanical and electrical characteristics.
