Abstract

Use: paint and varnish production, mixing in containers and bottling paints and varnishes in mechanical engineering and other sectors of the national economy while increasing the efficiency of mixing and pouring paints and varnishes from replaceable sealed containers with a narrow neck. Summary of the Invention: Medium h

Description

inlet for supplying pressurized fluid is made in the form of a guide pipe 10 spanning the drive shaft 1 with a clearance for a removable tight connection with the neck 5 of the container 4, communicated with an opening 12 made in its upper part with a source of compressed air and made with openings 17 parts thereof for communication with the cavity of the container 4.

The drive shaft 1 is made hollow to form an injection channel 6 with holes 3 in the lower part for communication with the cavity of the container 4 and hole 7 in the upper part for communication with the drain pipe 8. The mixing bodies are made in the form of flexible elongated cables 2.1. item f-ly, 1 ill.

The invention relates to a paint production and can be used for placing in a container and filling paint and varnish materials in mechanical engineering and other public households. A device for mixing and dispensing a liquid under pressure is known.

In the known device used compressed air for dispensing liquid from the tank.

A disadvantage of the known device is the impossibility of using it with a removable container, since it is a stationary device.

The closest to the technical essence and the achieved effect to the proposed is a stirrer-pump for mixing and filling paints and varnishes, containing a drive shaft with mixing elements fixed at its end and means for supplying pressurized fluid in the discharge channel communicated with the drain pipe.

A disadvantage of the known agitator-pump is the impossibility of using it in removable containers with a narrow mouth.

The purpose of the invention is to increase the efficiency of the process of moving and filling paints and varnishes from replaceable sealed containers with a narrow neck. The goal is achieved by the fact that in a mixer pump for mixing and pouring paints and varnishes containing a drive shaft with mixing elements fixed at its end, and means for supplying pressurized fluid to the discharge channel communicated with the discharge pipe, means for supplying pressurized fluid in the form of a guide tube covering the drive shaft with a clearance for a removable tight connection to the container neck, communicated with an opening made in its upper part with a source of compressed air supply ear and made with holes in its lower part for communication with the cavity

containers, wherein the drive shaft is hollow to form a discharge channel with openings in the lower part for communication with the cavity of the container and an opening in the upper part for communication with the drain pipe. Mixing bodies are made in the form of flexible elongated ropes. The drawing shows an agitator-pump placed in a tank with a small neck.

The mixer pump contains a hollow drive shaft 1 with agitating bodies fixed at its end in the form of flexible elongated ropes 2. In the lower part of the hollow shaft 1, holes 3 are made to communicate with the cavity of the container 4. The second end of the shaft 1 is rigidly connected to the pneumatic actuator 5. Shaft cavity 1 forms an injection channel 6 communicating through openings 7 made in the upper part of the shaft 1 with a drain pipe 8 fixed to the housing 9 surrounding the shaft 1.

The agitator pump has a means for supplying a pressurized fluid, which is designed to cover the driving

shaft 1 with a clearance of the guide tube 10 for removable tight connection with the neck 11 of the tank 4; In the upper part of the guide tube 10 extending beyond the tank 4, there is a hole 12 communicating with the compressed air supply system 13 through a pressure reducing valve 14 with a pressure gauge 15 and through a pneumatic valve 16. A fitting 17 communicates a pneumatic actuator 5 with a pneumatic valve 16.

At the bottom of the guide tube

10 holes are made to communicate with the cavity of the container 4.

The stirrer pump works as follows.

The stirrer pump is introduced into the container 4 and rigidly fastened in its neck 11. For insertion through the neck, the flexible elongated ropes 2 are brought together. Have a stirrer-pump lower end in the center of the bottom

barrels at an angle of 10-15 °. The rigidity of fastening and sealing is provided by a nut 18 with a seal 19. A fitting 17 is connected to the compressed air supply line (not shown}.) A paint supply hose is connected to the drainage pipe 8. Then the pneumatic actuator 5 is turned on and agitation is performed, which is provided due to the flexible elongated ropes 2. Under the action of centrifugal force, the elongated ropes 2 are located throughout the entire volume of the tank.

After the pneumatic valve 16 is turned on by means of a pneumatic valve 14, the pressure gauge 15 establishes an overpressure in the tank 4, which is necessary for an intensive outflow of paint from the tank 4,

h

Compressed air enters the cavity between the guide tube 10 and the hollow shaft 1 through the openings 17 in the container 4. Under overpressure, the paint through the openings 3 through the discharge channel of the shaft 1 enters the cavity of the housing 9 and flows out through the drain fitting 8.

The use of the proposed agitator-pump will allow to provide high-quality and intensive mixing of paints and varnishes in containers with a small neck, followed by their filling.
