Abstract

The invention improves the quality of cleaning by removing contaminants from the liquid during the washing process. When a centrifugal activator rotates in the bath, the particles of pollution are carried to the side wall of the bath and through the slot opening in it enter the chamber from which it is transported under the pressure of washing liquid through the inlet to the bottom of the tank for washing liquid. In the tank for washing liquid, solid soils settle in its lower part, and oily soils rise to the surface of the liquid in the upper part of the vessel. The cleaned fluid through the outlet nozzle with a hose installed below the upper level of the fluid in the tank is supplied by supporting and discharging into the upper cavity of the bath, bounded by the inner edges of the centrifugal activator blades. As a result, a final cleaning of the fluid is provided by additional circulation of fluid through the tank for washing liquid. 2 Il.

Description

The invention relates to the cleaning of products, namely to washing with a liquid.

The purpose of the invention is to improve the quality of cleaning by removing contaminants from the washing liquid during the cleaning process.

FIG. 1 shows a device for cleaning products, a vertical section; in fig. 2 is a sectional view in FIG. one.

The device contains a bath 1 with a lid 2 filled with washing liquid, a holder of 3 products, a centrifugal activator 4 with a drive 5, a tank 6 connected to a bathtub inlet 7 and an outlet pipe with a hose 8.

Bath 1 has a side wall 9, which can be made both cylindrical and in the form of a truncated cone with a large base at the top. The conical wall is connected to the upper transverse wall 10 by means of a section 11 made with torus surfaces.

Outside, a vertical chamber 12 is attached to the side wall 9, which is connected

the lower cavity with a capacity of 6 using the inlet 7 with a valve 13.

The cavity 14 of the chamber 12 communicates with the cavity of the bath 1 through a slot 15 in the side wall 9 of the bath, which is formed along a generatrix, and the second edge 16 of the hole 15 is bent into the cavity of the bath along the stream of washing liquid.

Lid 2 bath has a cavity 17, open into the bath. In this cavity, a valve 18 is installed, which in the lower position closes the connection of the cavity 17 with the bath cavity. The lid opening 19 of the lid, which goes into the lid cavity 17, is connected to the cavity 20 of the tank 6 below the upper level of the liquid in it using the outlet nozzle with the hose 8. In the upper position of the valve 18, the cavity 20 of the tank 6 through the outlet pipe and the hose 8 of the lid 17 of the lid are connected with bath cavity 1.

The centrifugal activator 4 is made in the form of a horizontal carrier disk 22 mounted on a drive shaft 21 with blades 23 fixed on its periphery, on the upper ends of which there is an upper end cover 24 of the blades having an opening 25 for passage of fluid from the walls of the bath into the cavity bounded by internal edges blades. The top wall of the end cover of the 24 blades is raised and made in sections of tore surfaces.

The torus wall 26 of the end flap 24, together with the torus surface 11 and the upper transverse wall 10 of the bath, form a smoothly narrowing annular channel 27.

blades and cavity of the bath bounded by the inner edges of the blades of the activator, and the circuit for cleaning the fluid, including the bath cavity outside the blades of the activator 4, cavity 14 of chamber 12, inlet 5 of nozzles 7, capacity 6, outlet of nozzle 8 with hoses 8, cavity of the lid 17 and bath cavity, limited by the inner edges of the blades of the activator 4.

Washing liquid falling into the cavity

Q outside the blade activator, rotates at a peripheral speed equal to the speed of rotation of the outer edges of the blades. Due to the centrifugal forces, the particles of pollution are carried to the surface of the side wall 9 of the bath and, moving along it, fall

As a result of this constriction, the pressure increases through the slot-hole 15 into the inner

Molding in the cavity bounded by the outer edges of the blades and the side wall of the bath. Due to the pressure in the cavity between the blades and the side wall of the bath, as well as the vacuum created in the cavity bounded by the inner edges of the blades, the circulation of washing liquid through the working circuit (inside the bath) and through the cleaning circuit (through the tank) is improved.

The product holder 3, located in the cavity bounded by the blades, is made in the form of a lattice container and is fixed with. using a support ring 28 supported on the upper transverse wall 10 of the bath.

the cavity 14 of the chamber 12, and from there into the container 6.

In the tank 6, a liquid separation takes place: solid contaminants settle in the lower part 31 of the tank, and oily contaminants rise to the surface of the liquid in the upper part 30 of the tank. The cleaned fluid through the outlet with the hose 8 is fed through the lid cavity 17 into the bath cavity bounded by the inner edges of the blades.

To remove the holder with the products, the valve 13 and the valve 18 are set to the closed position.

After the next installation of the holder for cleaning products, the cover connecting it with the cavity 14 of the chamber 12 is fixed, the valve 13 is opened and the valve 18 is opened and supplied with a transverse partition 29 dividing the container into the upper 30 and lower 31 parts, interconnected by a pipe 32 fixed to the partition 29. The partition 29 with the pipe 32 eliminates the direct flow of fluid from the inlet 7 to the outlet with the hose 8. To facilitate the separation of solid contaminants, the lower end 33 of the additional container b is tapered It is equipped with a lid 34. To drain oil contamination, an additional container in the upper part is equipped with a drain pipe 35 with a crane 36.

A device for cleaning products works as follows.

With the product holder 3 fixed in the bath, the valve 13 and the valve 18 are placed in open positions and the washing liquid is poured into the device and the outlet of the outlet with the hose 8 into the container 6. The rotational drive of the vane activator 4 is activated. In the cavity between the outer edges of the activator blades and an excess pressure occurs in the side wall 9, and a vacuum occurs in the cavity bounded by the inner edges of the blades of the activator 4. Due to this, two circuits of fluid motion arise in the device; a working circuit that includes the cavity of the bath outside the blades of the activator 4 and a narrowing channel on top

the process is repeated.

The invention improves the quality of cleaning products by removing contaminants from the liquid during the cleaning process, while the centrifugal activator that circulates the liquid through the working circuit (inside the bath) also provides circulation through the liquid cleaning circuit (through the tank). The bath itself serves as a pre-centrifugal device.
