Abstract

The invention relates to devices for mixing paste-like, viscous materials with their degassing and can be used in the chemical, oil refining, food industry, microbiological, pharmaceutical and other industries. The goal is to improve the quality of the processed material by reducing its gas content during unloading. The material is loaded through the pipe 10 into the housing 1, the lid 2 is closed and the actuator 6 of the stirring organ 5 is turned on, which is agitated according to the epicyclic curve with the HELP AND mechanism 7. To degas the pipe 9 is connected to the vacuum system. In the cavity of the diaphragm 3, a vacuum is created to press the diaphragm 3 against the lid 2. At the end of the mixing process, the material is discharged. For this, the stirring member 5 is stopped against the wall of the housing 1. The means 4 is turned on for injecting compressed air into the cavity of the diaphragm 3. Lastly, expanding, unloads the material through the nozzle 10.

The invention relates to devices for mixing paste-like and viscous materials with their degassing and can be used in chemical, oil refining, food, microbiological, pharmaceutical and other traces of conglomeration.

The purpose of the invention is to improve the quality of the processed material by reducing its gas content during unloading.

The drawing schematically shows a device for mixing and degassing highly viscous and pasty materials.

The device consists of a conical body 1, a lid 2 mounted on the lid of an elastic diaphragm 3, having means 4 for injecting compressed air and evacuating the cavity of the diaphragm, a mixing body 5 in the form of a rod entering the body 1 from the bottom, an actuator 6, a toothed-lever mechanism 7, providing movement of the moving member 5 along an epicyclic curve and stopping it against the wall of the housing; bellows 8 for sealing the housing 1. The housing 1 is equipped with a connecting pipe 9 for suctioning gas and a connecting pipe 10 for unloading material located in the bottom th part of the body.

The device works as follows.

The material is loaded through the pipe 10 into the housing 1. The lid 2 is closed and the actuator 6 of the stirring organ 5 is turned on. The mixing organ 5 is moved in the housing 1 along an epicyclic curve using a gear-lever mechanism 7. To degas the material during the movement, the pipe 9 is connected to vacuum system (not shown).

At the same time, the means 4 for evacuating the cavity of the diaphragm 3 are turned on, as a result of which the diaphragm is pressed against the lid 2 without moving the process. At the end of the transfer process, the material is loaded. To do this, stop the stirring member 5 against the wall of the housing 1. Include means 4 for injecting compressed air into the cavity of the diaphragm 3. The diaphragm 3 expands and squeezes the material through the nozzle 10.

After unloading the material, the nozzle 9 is connected to the atmosphere through a three-way valve (not shown) and the air is vented from the diaphragm cavity, then the lid 2 is opened. Then the cycle repeats.
