Description

Utility Model Description

Mixing and grinding plant

relates to the field of processing bulk, fibrous and polymeric materials in dry form and in a mixture with liquid components and can be used to prepare paste-like mixtures from these components.

There are known various types of mixers and mills used in industry that perform independent functions that are not mutually interconnected.

Closest to the technological nature of the proposed installation is a production line consisting of sequentially mounted tanks for heating liquid components, a mixer for displacing dry and liquid components, a conveyor belt and a grinding mill.

A disadvantage of the known production lines is the increased consumption of energy resources, since each type of equipment included in the production line has an independent energy drive.

The production line requires large production areas. To cool the mill, cold water is supplied to its shirt, which is not used in the production line.

To heat the liquid components, a coolant (heated water) is supplied to the tank jacket from an independent heat supply source.

The aim of the proposed installation for mixing and grinding is to reduce operating costs due to the compactness of the installation, reduce energy consumption, increase productivity.

The goal is achieved by the design features of the installation.

A screw is mounted in the bottom of the housing of the mixing unit of the installation to supply mass to the grinding unit. The auger is driven into rotation by means of a clutch and a chain drive from a single drive with a mixer of a mixing unit mounted on its housing.

The use of an independent transmission mechanism from the mixing unit to the grinding unit is not required.

In the case of the mixing unit, an unloading hatch with a locking mechanism is also not required, since their role is played by a screw in the bottom of the body, which is also a unloading and feeding mechanism.

The installation provides for the use of cooling water leaving the grinding unit from the jacket. When grinding the components, a high temperature is formed and cooling water leaves the jacket with a temperature of (60-80) degrees, which is sent to heat the liquid components located in the tank mounted directly on the body of the mixing unit.

The mixture from the mixing unit is fed by a screw into the housing of the grinding unit without an intermediate loading funnel. To evenly distribute the incoming mixture on a rotating shaft with bills, leveling blades are mounted.

The presence of the screw feeding the mixture directly into the housing of the grinding unit and the blades on the rotating shaft provide a forced flow of the mixture into the grinding zone, which increases the productivity of the installation.

The installation is mounted on a common metal frame and due to the lack of intermediate transmission mechanisms is compact, which saves production space and the ability to move it and install it anywhere without a foundation. The prototype is manufactured and tested. In FIG. I shows a general view of the installation. In FIG. 2 is a view A in FIG. 1 in FIG. 3-section BB in FIG. 1

The mixing and grinding installation consists of a mixing unit 1 with a skip hoist 2, a tank for liquid components 3, an auger 4, a grinding unit 5 and a selection screw 6 mounted on a common frame 7. A safety limit switch 8 is mounted on the body of the mixing unit, which disconnects the assembly mixing with the lid open 9.

Finger rotor 10, the mixing unit is driven by a drive 11 mounted under the housing of the mixing unit.

From the same drive through a chain gear 12 is driven into rotation by a screw by turning on the clutch 13.

The grinding unit consists of a housing 14 with a jacket 15, a rotating vertical shaft 16 from the drive 17 with leveling blades 18 mounted on the shaft and five disks with grinding elements 19 mounted on them.

Water for cooling the grinding unit and heating the liquid components in the tank of the mixing unit enters the jacket of the grinding unit through the nozzle 20, is discharged through the nozzle 21, then it is supplied to the heating of the liquid components in the tank jacket through the nozzle 22 and is discharged through the nozzle 23.

Installation works as follows.

Using a skip hoist 2, dry components are loaded into the mixing unit 1, liquid are poured from the tank 3, equipped with a level gauge to control the amount of liquid components to be poured.

The rotating finger rotor 10 mixes the components, while the screw 4 does not rotate. After the end of the mixing cycle, the clutch 13 engages the screw 4 and the mixture enters the grinding unit 5, in which the rotating blades 18 are uniformly and forcibly fed into the grinding zone.

Passing through the narrow gaps between the housing 14 and the grinding elements 19, the mixed components are frayed and form a paste-like mixture, which leaves the grinding unit through the lower funnel 24 and is taken out by the screw 6.
