Description

The invention relates to the field of purification of liquids, in particular large-volume circulating water, as well as process fluids (TFA), cutting fluids (coolant), washing solutions, and can be used in metalworking industries for metal forming, cutting and rolling.

A device is known "Integrated technology module for thin-layer cleaning of large volumes of water from mechanical impurities and oil products" (see Utility Model Patent No. 57269. Cl. С02F 1/40. Publish. 10.10. 2006 Bull. No. 28), containing the established in containers with treated water, packages of horizontally oriented elements, inlet and outlet pipes, gratings connected to the distribution and reception chambers.

The reasons that impede the achievement of the technical result indicated below when using the known device include the fact that the sediment accumulated on horizontally oriented elements is removed using knives that rotate around the axis by means of a drive. In addition, the known design involves the manufacture of horizontally oriented elements of durable steel sheets of stainless steel.

These circumstances sharply increase the cost of the known cleaning device, and the design of the open tank does not allow the use of these devices in pressure treatment systems.

The essence of the invention lies in the fact that the container with treated water contains a drain pipe for sediment removal, hollow elements made in the form of flat, rigid, perforated plates, covered with a mesh-substrate, on which a filter cloth is fixed, and the inner cavity of the elements is connected to the outlet camera, and the elements themselves are tilted relative to the horizontal axis in the direction of the drain pipe.

In addition, the container on the supply side of the liquid being cleaned is equipped with guide rods, and a platform made in the form of a float floats along the guide rods on the surface of the water. The platform itself is equipped with a pump, and on the upper part of the platform there is a comb with nozzles directed towards the hollow elements.

The use of the invention provides the following technical result:

- expanding the scope of the cleaning device,

- simplifying the design of the cleaning device and reducing its cost,

- improving the efficiency of the device.

The specified technical result in the implementation of the invention is achieved by the fact that the device is a technological module for thin-layer cleaning of large volumes of water from mechanical impurities, contains a container with treated water, inlet and outlet pipes, gratings connected to distribution and reception chambers.

The peculiarity lies in the fact that the tank with the water to be treated contains a drain pipe for sediment removal, hollow elements made in the form of flat, rigid, perforated plates covered by a mesh substrate on which a filter cloth is fixed, and the inner cavity of the elements is connected to the discharge chamber, and the elements themselves are tilted relative to the horizontal axis towards the drain pipe.

In addition, the container on the supply side of the liquid being cleaned is equipped with guide rods, and a platform made in the form of a float floats along the guide rods on the surface of the water. The platform itself is equipped with a pump, and a comb with nozzles directed towards the hollow elements is installed on the upper part of the platform.

The analysis of the prior art by the applicant, including a search by patents and scientific and technical sources of information and identification of sources containing information about analogues of the claimed invention, allowed to establish that the applicant did not find an analogue characterized by features identical to all the essential features of the claimed invention. The definition from the list of identified analogues of the prototype, as the closest in the set of essential features of the analogue, allowed us to identify the set of essential distinguishing features in relation to the applicant's technical result in the claimed invention set forth in the claims.

Therefore, the claimed invention meets the condition of "novelty."

The construction of the invention is presented in the drawings (Figs. 1-3).

Figure 1 - Section of the device in the purification mode of the liquid.

Figure 2 - A fragment of a hollow element.

Figure 3 - Section of the device in the washing mode.

The liquid purification device consists of a housing 1 made in the form of a sealed, elongated parallelepiped with a distribution 2, a receiving 3 and a discharge 4 cameras, a supply 5, a discharge 6 and a drain 7 nozzles, a grill 8, hollow elements 9, consisting of flat, rigid, perforated plates 10, covered with a mesh substrate 11, on which a filter cloth 12 is fixed, guide rods 13, platforms 14, pump 15, combs 16, nozzles 17, valves 18, 19 and 20, nozzles 21.

The device operates as follows.

In cleaning mode. The liquid being cleaned through the valve 18 (the valve 20 is closed) and the inlet pipe 5 is fed into the distribution chamber 2, and then through the grill 8 into the housing 1 of the device. Passing between the layers of hollow elements 9, the liquid is filtered through a filter cloth 12 into the inner cavity of the elements 9, from where it is discharged through the pipe 21 into the discharge chamber 4, and then through the pipe 6 and the open valve 19 to the consumer.

In flushing mode. With the accumulation of settled foreign impurities on the surface of the filter cloth 12 to a predetermined mass, the operation mode of the device is switched. In this case, the valves 18, 19 are closed and the valve 20 opens. The liquid flows by gravity through the valve 20 and starts to drain from the housing 1. At this moment, the pump 15 mounted on the platform 14 is turned on, which pressurizes the liquid into the comb 16 and then through the nozzles 17 directs it into the space between the elements 9, thereby washing away the sediment layer deposited on the surface of the filter cloth 12.

Going down the guides 13, floating on the surface of the drained liquid, the platform 14 with the pump 15 provide a flushing of all elements 9. The washable sediment together with the liquid through the pipe 7 and the valve 20 is sent to the further thickening device.

After the flushing mode, the valve 20 closes and the valves 18 and 19 open, thereby transferring the device to the liquid purification mode.

Filling the housing 1 through the nozzle 5, the liquid raises the platform 14 to the upper position and thereby prepares it for the washing mode.

The closed design of the housing 1 expands the capabilities of the device and allows its use in both pressure and pressureless systems for cleaning liquids.

The absence of any actuators with electric drive elements simplifies the proposed design of the device and reduces its cost.

The use of flat, rigid, hollow elements, covered with a mesh-substrate on which a filter cloth is fixed, can significantly increase the useful filtering area and thereby improve the quality of cleaning.

The proposed design of the hollow elements allows you to combine two cleaning processes: the deposition of foreign impurities from above on the surface of the elements themselves and filtering the liquid through the filter cloth both at the top and bottom of the hollow elements, which significantly increases the efficiency of the device.

Thus, the foregoing description indicates the fulfillment of the following set of conditions when using the claimed invention:

- a tool embodying the claimed invention, in its implementation is intended for the purification of process fluids (TJ), cutting fluids (coolant), washing solutions and can be used in metalworking industries for metal forming, cutting and rolling;

- for the claimed device in the form as it is described in the stated claims, the possibility of its implementation using the means and methods described in the application is confirmed;

- a tool embodying the claimed invention in the implementation, is able to ensure the achievement of the perceived by the applicant of the assigned technical tasks. Therefore, the claimed invention meets the condition of "industrial applicability".
