00 01 The invention relates to mechanical engineering, in particular to chemical and electrochemical processing of helium. A device for the chemical treatment of products is known, which contains passage chambers located along the process, a conveyor and an inkjet loop l. The disadvantage of this device is the need for a large amount of technological solution, which leads to an increase in production space and complicates the maintenance of the installation. A device for chemical and electrochemical treatment of products is also known, which includes chambers of preliminary operations, primary processing of final operations with collectors installed in them with nozzles and openings with nozzles for draining the process solution at the bottom of chambers 2. A disadvantage of the known device is the large the volume of the process solution and the intermediate tank, which causes an increased consumption of metal, takes up space, and complicates maintenance. All this increases operating costs. The purpose of the invention is to reduce operating costs and reduce equipment weight. This goal is achieved by the fact that a device for liquid processing of products, containing a series of chambers for technological operations, a system for supplying and draining solution with nozzles and pumps, is equipped with a diffuser installed above the drain nozzle at a height of (0.5-0.8) (3 the diameter of the nozzle aperture.The reflector is made in the form of a disk. The diameter of the disk must be 4-5 times the diameter of the drain hole, because the cone of the funnel formed in the liquid is 90 -110, therefore cone tilt angle ca 45-55. With the diameter of the drain screw OL, the diameter of the disk T) is equal to D d + 2 (-ta-55 ° .d) d +2 (1.78) d + 3.4 d 4.4 d 1 l excluding the exit of the funnel beyond disc diameter 1) take the height of the disc above the drain hole (0.5-0.8) d. FIG. 1 shows the device, a general view; in fig. 2 is a section A-L in FIG. one; in fig. 3 shows a section BB in FIG. 2; on .fig. 4 shows a section B-B in FIG. 3. The plant for chemical and electrochemical treatment of products contains chambers of 1 preliminary operation, chamber 2 of the main processing and chambers of 3 final operations with installed headers 4 with nozzles 5. Chambers 1-3 have holes 6 with nozzles 7 for draining the process solution bottom of 8 cameras. The chambers are integrated with an overhead conveyor 9. Difflectors 10 are installed in the holes b, made in the form of a disk. The disc diameter is 4-5 times the diameter of the drain hole b, and the disc is mounted on the legs 11 at a height equal to 0.5-0.8 of the diameter of the drain hole. The device works as follows. Without a difflector, when the process solution is sucked by the nozzle 7 through the pump orifice with an insufficient height of the process solution in chambers 1-3, a funnel forms, which leads to air entering the working cavity of the pump and disrupting the normal flow of the process solution to the nozzles 5, and also causes cavitation, which leads to the destruction of the pump impeller. The proposed device eliminates the formation of a funnel and creates conditions for the impossibility of the occurrence of a circular current of the process solution around the suction axis. The device creates conditions for the horizontal flow of fluid in the operation of the suction inlet. Above the overlap, conditions are created for the vertical fluid flow due to a decrease in the level of the process solution sucked by the pump. Compared with the base object, the proposed device allows to drastically reduce the volume of the process solution and, as a result, eliminate the intermediate tank. The exclusion of the intermediate tank will allow, on average, saving up to 1.5 tons of high alloy steels per installation per year, which, depending on the cost of the material, is 10–12 thousand rubles.
