Description

The invention relates to the field of cleaning parts and components of machines, in particular to technical equipment for washing various products, and can be used in repair shops and in mechanical engineering.

The aim of the invention is to improve the quality of cleaning.

The drawing shows schematically an installation for washing products, a general view.

The unit for washing products has a washing chamber 1 with a compartment for washing liquid, the chamber is made in the form of an octahedral bath with a lid 2. In the washing chamber 1 in the inner corners there are mounted collectors 3 with nozzles 4, holder 5 of product 6. Holder 5 is equipped with for its incorporation (not shown) with respect to the collectors 3 with nozzles 4. The installation includes a tank 7 for washing liquid, equipped with a cleaning means, for example, a hydro cyclone 8, a pump 9 connected by lines 10 to tank 7 and lines 11 to collectors 3. In line 10 sun that exactly closing device 12 for example zadvizh.ha. The plant is equipped with an additional tank 13 and a pump 14, shut-off valves 15 and 16. The additional tank 13 is connected by supply lines 17 and supply lines 18 and 19 of the working fluid with the main tank 7. The additional pump 14 is of adjustable capacity, installed in return line 18 The working fluid is additionally connected to the washing chamber 1 by line 20 via a shut-off valve 16. A shut-off valve 15 is installed in line 18 between the pump 14 and the additional tank 13. In the washing chamber 1, a mesh is installed in front of the line 20 filter 21.

Installation for washing products works as follows.

In the washing chamber 1, a pad is installed, the product 6 is cleaned, the lid 2 is closed and the drive is turned on, a product (not shown). Pumps 9 and 14 are turned on with the shut-off valve 16 fully closed and the shut-off device 12 and shut-off valve 15 completely open. The washing fluid from the pressure line 1 is supplied to the nozzles at the collectors 3, the washing chamber 1 is flushed. supplied by the pump 14 to the hydrocyclone 8 of the tank 7 for the washing liquid, thereby replenishing the liquid flow in the latter. The capacity of the pump 14 is adjusted so that when pumping the fluid last into the hydro cyclone 8, it is necessary to protect the tank 7 for the washing liquid from overflowing, i.e., to balance the flow rate of the liquid in the pressure line 11 and in the line 18.

As the washing liquid enters through the collector 3 with the nozzles 4 into the washing chamber 1, the compartment for washing liquid 1 is filled to the specified

level, which is established after the additional tank 13 is completely emptied. The volume of the additional tank 13 is equal to the compartment for washing liquid of the washing chamber 1. After filling the washing chamber 1, during which the

continuous cleaning of the rotating product 6, close the shut-off valve 15, the shut-off valve 16 is slightly opened, and the capacity of the pump 14 is set at which the flow rate of the fluid pumped by the pumps 9 and 14 are equal. There is a jet cleaning operation. At the same time, the product 6, as it rotates in the upper part of the washing chamber 1, is cleaned by jets and in the lower part by immersion. The activity of the submersible wash is enhanced by jets from the nozzles 4 of the collectors 3 located in the lower submersible part of the washing chamber 1.

At the end of the jetting operation, the check valve 16 is fully opened, and the capacity of the pump 14 is set to double the capacity of the pump 9, resulting in an excess liquid in the tank 7 for the washing liquid. Excess washing liquid through line 17 flows into the additional tank 13 until the washing chamber 1 is completely empty. Simultaneously with the emptying, the process of rinsing the product 6 with the washing liquid supplied by the pump 9 continues.

During the cleaning process, the washing fluid supplied by the pump 14 via the return line 19 to the washing fluid tank 7 is cleaned in the hydrocyclone 8 built into it.

After the washing cycle is completed, open the cover 2 and unload the product 6.

The emergency discharge of the washing liquid from the tank 7 is carried out into the washing chamber 1 via an emergency pipeline (not shown). In the additional tank 13, storage, heating, and disinfection of the washing liquid can be performed.

The present invention allows for the production cycle of a product wash with a jet-cleaning operation, in which the washing liquid from the supplementary tank 13 is included in the liquid recirculation system, while improving the quality of cleaning and reducing the time of the technological cycle by eliminating the time just setting when switching from one washing operation for each

5 subsequent and due to the combination of jet and immersion washing in a single continuous operation.
