CZ1955U1 - Apparatus for manufacture of cement, lime, clay, plaster barite and other suspensions - Google Patents

Description

The invention relates to equipment for the production of cement, lime, clay, gypsum, barite and other suspensions as well as mixtures thereof for the purpose of drilling and injection work, reinforcement of foundation soils, slurry jet cutting, jet injecting.

BACKGROUND OF THE INVENTION

So far, cement and other suspensions have been manufactured using a reservoir containing a solid component (most often Vcement), a screw conveyor, a mixer, a storage tank and associated pumps. This equipment has to be dismantled after the completion of the work on the specific construction site, moved separately and re-assembled at the new site. In operation, the device is clogged with a hardened stirred suspension, which must be removed regularly. Another source of difficulties is the screw conveyor as it is packed with the conveyed material during operation.

The essence of the technical solution

The essence of the technical solution is a device for dosing and mixing the components produced by the suspension and a device which realizes this concept. It is based on a solution which consists of a dispenser composed of a rotor with blades disposed in the housing, to which the activation mixer consisting of a rotor with blades disposed in the housing is connected. The mixer concept is based on several basic ideas. The components of the suspension enter the mixer simultaneously; thus, the volume of the operating reserve in the following equipment can be kept to a minimum, thereby reducing the dimensions of the entire apparatus.

Furthermore, the use of a paddle dispenser removes the malfunctioning screw conveyor considerably while allowing a complete mixer to be placed in the space below the hopper.

Emphasis is placed on preventing clogging of the inner walls with dried suspension.

The large burner replaces the high-speed activation mixer. It greatly simplifies moving between construction sites and increases operational readiness. Low operating demands and low power consumption along with low flushing losses are further advantages. Dust-free operation, the possibility of automatic operation and little occupation at the construction site are also negligible

Examples of technical solution

The mixer consists of an inlet hopper 1 to which a paddle dispenser 9 composed of a rotor 2 with blades 3 is connected. There are several types of rotors, they differ in the number and shape of the blades according to the required output and the material to be transported (cement; clay: gypsum). The housing 4 comprises a steel tube with cut-outs for inlet from the reservoir and outlet to the hopper and activation mixer. In the funnel-shaped transition 5 between the dispenser and the mixer, a layer of water (primary suspension) is formed on the walls which prevents contamination of the inner walls and carries the stirred suspension into the activation mixer which, together with the dispenser, substantially determines the parameters of the device. It consists of a rotor 6 with blades 7 and a casing 8 of steel tube with cut-outs for inlet of the mixture from the hopper and exit to the storage tank.

Function of the device subject to the technical solution:

The stock of powdered raw material (mostly cement) for the production of the mixed suspension is stored in a vertical cylindrical container (so-called Sil).

From there it flows freely through the hopper closure and hopper 1 to the vane dispenser 19. Rotation of the rotor 2 of the vane dispenser provided with the vanes 3 produces a uniform current, which can be adjusted or adjusted by varying the speed. completely stop. This stream in the funnel-shaped transition 5 impinges on the water separation layer (or primary suspension) and enters the activation mixer together.

In the activation mixer 11, the rotor 6 provided with the blades 7 rotates the grain aggregates rapidly and mixes the suspension produced.

It continuously flows from the mixer through a mesh filter into the storage tank. The suspension parameters can be extensively controlled by changing the shape and speed of the metering rotor, by varying the flow rate of the water or the flow rate. by changing the composition of the primary suspension.
