2003116718 Installation of a circulation washer

The utility model relates to circulating washing devices without disassembling washable objects, and can be used for washing pipelines and equipment, for example, in technological lines of food industry enterprises.

Known installation of circulation washing pipelines and

reservoirs containing a pump, sensors for media separation and filling control of the washing facility, pipelines and valves 1. The disadvantage of this device is the presence of only one washing circuit, which prevents the use of both acid and alkaline cleaning solutions.

The closest in technical essence is a sink containing tanks for rinsing water, washing solutions, pumps for supplying and returning solutions, pipelines and valves. To automatically maintain the concentration of detergent solutions, a dosing system of concentrates of detergent and disinfectant solutions 2 is used.

The disadvantages of this device include the availability of devices for controlling the concentration of solutions, significantly complicating and increasing the cost of the design.

The proposed circulation washing installation comprises at least one washing solution tank connected by a supply pipe to a water supply system and a drain pipe with a sewage system, a solution supply pump connected to the tank by a suction pipe by means of a controlled valve and a three-way valve, a solution return pump, a pressure pipe and a controlled distribution a valve associated with the reservoir. A solution overflow pipe connected to a controlled distribution valve is connected to the tank above the liquid level, but below the pressure pipe. For automatic control of the control valve, a liquid level sensor is installed.

A washing solution can be prepared using an installation containing a pump, the discharge pipe of which is connected directly to the tank, and the suction pipe is connected to the tank by means of a three-way valve and a funnel with a valve installed in front of the pump.

The connection of the overflow pipe to the solution is higher than the liquid level, but below the pressure pipe simplifies the design and increases the reliability of the installation, since in case of automatic malfunctions, the solution remaining in the pipelines after washing is displaced by the water into the tank to a predetermined level, when filling above this level, the displacing water is drained through the overflow pipe down the drain. Due to this, a guaranteed return of detergent solutions without a significant reduction in their concentration is ensured. At the same time, there is no need to install concentrometers, reuse of washing solutions is ensured, and their consumption is reduced.

The use of several tanks for the washing solution in the installation allows the use of several solutions for washing, for example, washing acid, washing alkaline, disinfecting solutions at each washing, without shifting the solutions together.

The use of a unit containing a pump and a funnel with a valve for the preparation of a washing and solution solution allows the use of not only liquid, but also powder concentrates.

This utility model is illustrated in the drawing.

In FIG. 1 shows a practical diagram of the installation of a circulation wash.

Installation for circulation washing consists of tanks for water 1 and washing solution 2, supply pumps 3 and return 4 solution. The supply pipelines with taps 5 are connected to the reservoirs and are connected to the water supply system for supplying water during the preparation of solutions and washing the reservoirs. Cranes 6 are installed on the outlet pipe connecting

reservoirs 1 and 2 with sewage. On the suction pipe of the solution supply pump 3, controlled valves 7 are installed, which serve to automatically supply solution and water during washing, a three-way valve 8 and a valve 9 for duplicating the operation of the installation in manual mode. The solution return pump 4 is connected by a pressure pipe through a controlled distribution valve 10 to a reservoir. The valve 10 is connected to a solution overflow pipe 11 connected to the tank above the liquid level, but below the pressure pipe. The installation for preparing the solution 12 consists of a pump 13, the discharge pipe connected directly to the tank 2. The suction pipe the pump is connected to the tank through a three-way valve 8, a funnel with a valve 14 is installed in front of the pump. The liquid level sensor 15 is functionally connected to the valve 10.

Installation works as follows. When preparing the solution, the tank is filled with water from the water supply through the tap 5, the tap 6 is closed. After that, through a three-way valve 8, using a pump 13, water is circulated. the components are loaded into the funnel 14 and under the influence of rarefaction enter the pump 13. In the inter-blade channels of the pump 13, the final mixing of the dry powder with the liquid without the formation of lumps takes place. You can also use liquid concentrates that are loaded directly into the tank and mixed with water as a result of circulation through the pump 13 or a mechanical stirrer.

When washing equipment, taps 5 and 6 are closed. The solution through the valve 8 and valve 7 by the pump 3 is pumped through pipelines and equipment, removing impurities. The contaminated solution by pump 4, through the valve 10 is fed back to the tank. After washing, the remaining solution in the pipelines is displaced by the wash water supplied by the pump 3 from the tank 1, back to the tank for the washing solution 2 to a predetermined level. When filling above the level, according to the signal of the liquid level sensor 15, the valve 10 directs the water to the overflow. In case of malfunctions in the automation, water is drained through the overflow solution 11 connected above the level

liquid, which prevents a decrease in the concentration of the washing solution. The operation of the installation can be carried out both in automatic and in manual mode.

After the solution as a result of repeated use becomes unsuitable for washing, it is drained through the faucet 6. The tank is washed with water supplied through the faucet 5.

Using the proposed installation of circulation washing will ensure high-quality washing of equipment, with guaranteed return of detergent solutions without reducing their concentration. At the same time, there is no need to install expensive concentrometers, reuse of washing solutions is ensured, and their consumption is reduced.
