Abstract

The invention relates to a foundry, where molding and core mixtures based on grain and powdered fillers are used. The purpose of the invention is to simplify the design, increase the reliability and efficiency of the mixer. The activator-mixer contains a corpus, a loading chamber, a carrier with support bearings, working chambers with augers symmetrically with the central axis and drives for rotating the carrier and working chambers. The drive of the working chambers and the carrier is made in the form of a crank 27 rotating on a stationary vessel, having a rotation axis on the central axis interacting with rods 34, each of which is connected to the working chamber eccentrically relative to the working chamber axis with the opposite end 11.1-il.

The invention relates to a foundry industry where molding and core mixtures based on grain and powder fillers are used, and can be used for abrading, grinding and mixing solid and liquid materials.

The aim of the invention is to simplify the design, increase the reliability and efficiency of the mixer.

The drawing schematically depicts a; tweeter-mixer,

The activator-mixer consists of a housing 1, inside of which a LED 2 is installed by means of a fixed shaft 3 having supports 5 installed on the base 4 with inserts

6. Vodilo 2 contains disc parts.

7, connected by links 8, and the hubs 9, inside of which the bearings 10 are mounted, forming a support for the rotation of the carrier 2 on the fixed

shaft 3.

In the carrier 2, in the disk parts 7, the working chambers 11 are mounted, having a bearing of rotation on the bearings 12. The internal cavities of the working chambers 11 are expanded. unloading material.

In the working chambers 11 on the material loading side, screws 14 are installed by means of ribs 13, the ends of which extend into the chamber with the material formed by the shell 15, the fixed ring 16, ending with a seal 17, and fixed to the hub 9 of the carrier 2 by a ring 18, ending with another. Sealer 19. The material is loaded through the throat 20.

The receiving chamber for the processed material is formed by an end sheet 21 and an annular shell 22 having a discharge opening at the bottom for feeding the material to the feeder 23 and at the top of the exhaust pipe 24 for connection to the ventilation. Between the annular shell 22 and the disc part 7 of the carrier 2, a seal 25 is installed, and between the end sheet 21 and the hub 9 of the carrier 2, a seal 26.

The rotation drive of the working chambers 11 and the carrier 2 is driven from the crank 27, which receives rotation from the pulley 28 connected to the crank 27 by means of the sleeve 29. The sleeve 29 is supported

on a stationary shaft 30, around which the pulley 28 and the sleeve 29 rotate by means of bearings 31., The stationary shaft 30 is installed in the support 32 with an insert 33, Crank 27 is pivotally connected to rods 34, the opposite ends of which are also connected pivotally and eccentrically relative to the axes of the working chambers flanges 35 mounted on the shanks 36 of the working chambers 11 by means of fingers 37.

The device works as follows.

The drive is turned on for the rotation of the pulley 28, transmitting the rotation to the crank 27. The latter, rotating around the central axis of the carrier 2, transmits motion to the cranks 34, which perform a complex flat-spatial motion. At the same time, the working chambers 11 due to the eccentric connection of the rods 34 with them rotate around their axis in the bearings via bearings 12 and through these supports due to the component force from the rotation of the rods 34 rotate the carrier 2 together with the outer bearing holders 10.

The material is processed; through the neck 20 into the chamber for delivery of the material, in the cavity of which the screws 14 rotate together with the workers

chambers 11. A part of the material, pads downwards, falls into the zone of rotation of the screws and is entrained in the internal cavities of the working chambers 11. The material deposited at the bottom of the chamber following cycles, when rotating screws hit the material zone, is gradually fed into the working chambers 11.

In the working chamber 11, the processed material acquires a complex mechanical movement, as a result of which mutual separate particles are rubbed together and against the walls of the working chamber. In this case, the material moves in the direction of expansion of the internal cavity of the working chamber. The processed material, the exit from the working chambers 11, enters the receiving chamber and through the discharge window enters the conveyor. The process of loading the working chambers with the material, processing and unloading takes place continuously.

The use of the proposed activator-mixer allows to combine the drive of rotation of the working chambers and the carrier and by simplifying its design 1447523
