SU547222A2 - Continuous plant for concrete mix - Google Patents

Description

The invention relates to concrete mix preparation plants used primarily for the production of porous concrete, and may find application in the construction materials and construction industries.

Known installation on author.St. No. 229271, including a feeder, a horizontal drum with a loading, unloading parts and blades, with a vibrolock with a grating bottom mounted in the discharge part of the drum, and a rotating rotor and pipeline with regulating fittings installed in the loading part.

The purpose of the invention is to prevent an excess mortar from entering the ready-mixed concrete into the holding substance and to prevent the separation of the finished concrete mix.

This is achieved by the fact that the vibrating channel is additionally equipped with a protective visor located inside the mixer and is made of two parts, one of which is located outside the mixer, set at an angle to the first with a slope in the direction of transportation of the concrete mix.

The drawing shows schematically the proposed installation.

The installation of continuous action for the preparation of concrete mix consists of a horizontal drum 1, in the discharge part 2 of which is mounted on springs 3 vibratory channel 4 with a slatted bottom 5, located in a vibratory channel 4 installed inside horizontal drum 1. drum 1 is set at an angle to the first with a slope in the direction of transporting the concrete mix. Vibrating channel 4 has a mathic vibrator 6 and is additionally equipped with a protective visor 7 located inside the horizontal drum 1, filled with blades 8.

The installation works as follows.

When the horizontal drum 1 is rotated, the concrete mixture containing the beating of the mortar solution is dropped by the blades 8 onto the vibratory channel 4 and, due to the directional vibration, moves along it towards the top. In this case, an excess of the solution in the case of xx) substances is sifted out of the concrete mix through reputated bottom 5 and returns to the horizontal drum 1. The concrete mix with an excess of solution in the moving substance, falls off the blades 8 and flows down the drum 1

on the protective visor 7, it is returned back to the drum 1. Thus, the concrete mixture, passing through the trellised bottom 5 under the protective visor 7, is finally released from the excess mortar solution and is a filler uniformly coated with a stable layer of the solution in the extinguishing substance. When it hits the sloping part of the vibrating channel 4, the ready mixture is quickly discharged and, consequently, its further separation is prevented.

The use of the invention allows to obtain a homogeneous large-pore concrete with a minimum consumption of a substance.
