Description

The invention relates to devices for the liquid treatment of long metal products. A device for etching long products is known, comprising a bath with a cap and a ventilation system til. The disadvantage of this device is the need for costs for ventilation and gas cleaning facilities. A device for treating the surface of long products is known, comprising a pickle bath, a lifting edge with ribs and a hydraulic lock, made in the form of a groove, fixed on the C2 bath. A disadvantage of the known design is the absence of a complete bath sealing, which leads to the release of vapors into the atmosphere and necessitates additional ventilation costs. The purpose of the invention is to improve working conditions and reduce operating costs. The goal is achieved by the fact that a device for treating the surface of long products containing a pickle bath, a lifting cover with ribs and a hydraulic lock made in the form of a groove mounted on the bath is equipped with a housing system for maintaining the level of water in the groove of the hydraulic seal above the plane of the product’s not around the perimeter of the case. In this case, the edges of the lid on the input and output side of the products are made of elastic material. . FIG. 1 shows the proposed device, a longitudinal section; FIG. 2 shows a section A-A in FIG. 1j in FIG. 3 shows a section BB in FIG. 1. A device for continuous etching of long products, for example, wire 1, consists of a body 2, an etching bath 3, a lifting cover 4 and a filling device 5 for drawing a wire under the cover. Along the perimeter of the housing, on the outer side, is a chute 6, which is filled with water. The end sections of the gutter serve as a cooling and flushing bath. Drain pockets 7 are made on the outer sides of the gutter end sections. The lifting cover is provided with ribs 8 along the entire perimeter. The side walls of the casing are made above the end walls. In the end walls of the casing and drain pockets are made slots for the passage of the wire. The internal capacity of the housing is divided by two partitions 9 into three compartments. A pickle bath is located above the middle section, its side walls are higher than the end walls. In the end walls of the pickling bath, the slots are flush with the slots in the housing for passing the wire. In order to provide wire filling into the installation without raising the lug, there is a filling mechanism, which consists of the refueling bracket 10, two two-wheeled carts 11 located in the side sections of the groove, with brackets 12, two shafts 13 with asterisks, one of which is drive, connected to with brackets en transfer 14. The charging bracket 10 has openings for securing the wire to be filled. The holes are located exactly above the slits for the wire. The installation works as follows. In the chute 6 of the housing 2, such an amount of water is supplied that does not have time to flow out through the slots in the end walls of the chute. Water rises above the endcap of the hull walls and the gutter and, overflowing through them, flows directly or through the drain pockets 7 into the outer compartments of the casing, from where it is drained into the sewer or re-fed into the gutter. The supply of the pickling solution ensures that it overflows through the end walls of the pickling bath 3 into the middle compartment of the body, from where it is again fed into the bath. The wire 1, passing through the slits in the end walls of the gutter, the body and the pickling bath, is submerged in water and the pickling solution. The cover 4 is lowered and its ribs 8 are immersed in the water located in the channel over the wire. The interior is completely isolated from the external environment. To draw the wire under the snatch, the refueling mechanism is moved to the edge of the installation. The wire is attached to the charging bracket tO, the drive of the chain drive 14 is switched on, and the chains connected to the brackets 12j pull the carriage 11 to the bracket

10 under the cover to the other edge of the installation to exit from under the covers. The wire is uncoupled from the shackle and further movement is carried out. Since the holes in the bracket are located above the slots in the end walls of the installation, the wire immediately falls into the corresponding slots. When used in the installation of the filling mechanism, the front edges of the lid make flexible, for example, 148902t

rubber measures to ensure a smooth passage of the refueling bracket under the lid.

The expected economic effect 5 due to reduction of acid consumption for evaporation, costs for ventilation and gas cleaning facilities and preventable damage from environmental pollution will be 18 thousand rubles. 10 per year from using one device.
