Description

2. The device according to claim 1, About aphi - h and eusche eu with that, the suspensions and load-gripping mechanism are fixed on the load-lifting mechanism.

The invention relates to devices for protecting the environment from contamination by harmful chemicals, reduces the damage to folk products from acid corrosion and can be applied in metallurgy and mechanical engineering.

The purpose of the invention is to simplify the operation of the device.

Fig "1 shows a device with a flat cover suspended above the bath; FIG. 2 shows a device with a folding cover fixed on a lifting mechanism (the cover is raised and folded); on fig.Z - the same view from the end of the bath; figure 4 - the shelter is lowered onto the bath.

The device shown in Fig. Contains a bath 1 filled with mineral acid, a shelter 2 in the form of a flat shield, suspensions 3, blocks 4, a winch 5, a workpiece 6 and side suction 7.

The device shown in FIGS. 2-4 contains a bath 8 filled with mineral acid, a shelter 9 in the form of folding doors, a hoist 10 with suspensions 11, stops 12 and an automatic load gripper 13, a revolt 14 of processing, a Baying material, a folding mechanism 15 and open flaps, side pumps 16. Cover sheets 9 are made in the form of light frames from plastic pipes, needle-punched material (polyester or plastic) with a thickness of 10-15 mm is pulled on the frames. The telpher 10 is installed on a bridge crane (not shown), in the cab of the crane operator control mechanism 15.

The device shown in figure 1, works as follows.

By means of suspensions 3, blocks 4 and winches 5, cover 2 rises to the highest position. Then with

3. The device according to Claims 1 and 2, t - which is characterized by the fact that the shelter is made in the form of flat flaps located above the load gripping mechanism and is equipped with a system for folding and opening the flaps.

using a runway beam (not shown), which is brought under the shelter, the treated article 6 is loaded into bath 1 and the crane beam is taken away from the shelter. Shelter 2 is lowered onto the sides of bath 1 and the product 6 is being processed. During processing, the shelter prevents harmful inclusions from entering the space above the bath. The cover is then lifted and the treated product is unloaded with a crane. Through the side pumps 7, the harmful inclusions are removed to the gas cleaning system. . ,

Similarly, the device shown in Fig.2-4 works. The telpher 10 by means of automatic load gripping 13 seizes revolt 14 of the material being processed and transfers it to the bath 8. The flaps of the shelter 9 are folded at this time and do not interfere with the crane operator to observe the working area. Simultaneously with the lowering of the riot 14 into the bathtub, it is lowered onto the sides of the bath,. and shelter 9, after which the shutter flaps are opened using mechanism 15. In this position, the device remains until the processing of revolt 14 is completed. the drip state and the droplets that form are drained into the bath. If necessary, the suspensions 11 can be disconnected from the hoist 10 for the time of metal processing and the hoist valve can be retracted to perform other work. After the mineral acid has completed the riot treatment, the riot is discharged in reverse order. In this case, the bath remains without shelter, however, in

the period of idle run of the bath, the emission of harmful substances is insignificant and their removal is ensured by onboard suction and general supply and exhaust ventilation.

Figg

Thus, in the proposed device, the cover is never left under load, which makes it easier to operate the device.
