Description

The utility model relates to non-ferrous metallurgy, in particular to the electrolytic method for producing magnesium. The proposed unit for removing sublimates is designed for cleaning the hogs of the sanitary suction system of magnesium electrolyzers.

In the process of electrolytic production of magnesium in magnesium electrolyzers, anode chlorine gas is formed, saturated with chloride vapors. Part of the anodic chlorine gas is removed into the collection cell by a circulating electrolyte, from where the gases are transported through the ducts of the sanitary suction system (SST) to gas purification for further neutralization. During the movement, chloride vapors cool down and are deposited in the hogs of the service station system in the form of sublimates, which are fine dust. Maintenance of the service station system is carried out by timely cleaning it from sublimates. Cleaning of the hogs of the service station system is carried out with the current load removed on a series of electrolyzers and the smoke exhausters turned off. The sublimates are unloaded manually using shovels, followed by filling the containers.

The disadvantage is that this operation is a gas-hazardous work, and is performed in insulating personal respiratory protection equipment, while the time for cleaning the hog is limited, since the current load is turned off once a month and for a period of 1.0 hours to 1. 5 hours, which is not enough to completely clean the hogs from sublimates.

The task to which this useful model is aimed is to create a device design that will allow mechanizing the operation of cleaning the hogs of a sanitary suction system.

The technical result when using a unit for removing sublimates is to increase the efficiency of cleaning the hogs of the sanitary suction system.

The specified technical result is achieved by the fact that a unit for removing sublimates is proposed, containing a cylindrical container, a sublimate supply pipe, a removable lid with a vacuum pipe, a grid with a fabric filter located in the upper part of the cylindrical container, and installed above the sublimate supply pipe; a device for supplying sublimates, consisting of an external suction flexible pipe and a socket, with the upper part of the external suction flexible pipe inserted into the sublimate supply pipe; hatch for unloading sublimates with a hinged lid located in the lower part of the cylindrical container.

The utility model is illustrated by drawings.

In fig. 1 and 2 show a general view of the unit for removing sublimates.

In fig. Figure 3 shows a section along section A-A.

The unit for removing sublimates is made in the form of a cylindrical container 1, closed with a removable lid 2 with a branch pipe 3 for vacuuming. In the upper part of the cylindrical container 1 there is a grate 7 with a fabric filter 8, and it is installed above the branch pipe 6 for supplying sublimates. A device for supplying sublimates, consisting of an external suction flexible pipe 4 and a socket 5, with the upper part of the external suction flexible pipe 4 inserted into the branch pipe 6 for supplying sublimates. At the bottom of the cylindrical tank 1 there is a hatch 9 for unloading sublimates with a hinged lid 10.

An example of the operation of a unit for removing sublimates.

The unit for removing sublimates is used to clean the hogs of the sanitary suction system of magnesium electrolyzers. First, a vacuum pipe 3 with a diameter of 38 mm and a height of 65 mm is rigidly attached (welded) to the removable cover 2, made of steel grade St 3 GOST 14637-89, to connect to the vacuum system of the workshop and create a vacuum in the cylindrical container 1. In the top parts of the cylindrical container 1 install a grid 7 with a fabric filter 8 to prevent dust (sublimates) from entering the vacuum line. Glass filter bag TSFR(B)-7s(94.5) GOST 10146-74 is used as a fabric filter 8. At a distance of 200 mm from the top of the cylindrical container 1, a pipe 6 for supplying sublimates to the unit (150 mm long and 100 mm in diameter) is rigidly attached (welded). To clean the hog of the service station system, a device for supplying sublimates is connected to branch pipe 6 for supplying sublimates. The device for supplying sublimates consists of an external suction flexible pipe 4 (pipe diameter 100 mm and length 10000 mm) and a socket 5 in its lower part. The upper part of the external suction flexible pipe 4 is installed in the branch pipe 6 for supplying sublimates. To unload sublimates from the unit, a hatch 9 for unloading sublimates (400 mm in diameter) with a hinged lid 10 and attached with a clamp is installed in the lower part of the cylindrical container 1 (100 mm from the lower edge of the cylindrical container). The unit for removing sublimates, prepared for operation, is closed using a tap with a removable lid 2 with a pipe 3 for evacuation. Then the removable cover 2 is attached to the cylindrical container 1 with eccentric clamps, and the sublimate removal unit is transported using an overhead crane to the “0” mark to the hog of the sanitary suction system of the magnesium electrolyzer. The cylindrical container is connected to the vacuum system of the workshop through pipe 3 for evacuation. The hatch of the hog of the sanitary suction system of the magnesium electrolyzer is opened, and the external suction flexible pipe 4 with a socket 5 is lowered into the hog of the sanitary suction system. In the cylindrical container 1, an excess vacuum of up to 5 kPa is created by opening the three-way valve of the vacuum line, sublimates begin to flow into the cylindrical container 1. After cleaning the hog of the service station system, the outer suction flexible pipe 4 with the bell 5 is removed from the hog, and the vacuum is turned off with a three-way valve. Sublimates are unloaded through hatch 9 with a hinged lid 10 into a technological box, from which, as they accumulate, they are sent for further processing.

Thus, the proposed design of the unit for removing sublimates makes it possible to mechanize the operation of cleaning the hogs of the sanitary suction system and increase the cleaning efficiency.
