Description

Device is broken up to three-layer drying-machine inner tube

Technical Field

The utility model relates to a drying equipment field, concretely relates to device is broken up to a three-layer drying-machine inner tube.

Background

The copper anode mud (copper mud for short) is adhered to the surface of copper anode and is insoluble in electrolyte in the electrolytic refining process

The copper sludge is an important raw material for extracting valuable metals such as copper, silver, gold, platinum group metals and the like. The water content of the copper sludge is generally 82%, wherein the copper sludge contains attached water and crystal water, the proportion of the attached water is not large and is about 5% -20%, and the proportion of the crystal water is about 60% -80%. To extract valuable metals from copper sludge, water in the copper sludge should be removed first. Since the crystal water can be removed only by heating the copper sludge to over 180 ℃, if a natural stacking and drying method is adopted, the crystal water in the copper sludge is difficult to remove. And the copper mud is granular after being dried and dehydrated, the granules are micron-sized, and the copper mud is extremely easy to float in the air to cause air pollution and harm the health of people, so the copper mud can be dried only by a drier.

When the drier is used for drying the copper mud, the copper mud can be agglomerated after entering the drier due to the viscosity of the copper mud, so that the copper mud needs to be scattered by a rotating scattering device arranged in the drier, the copper mud is fully contacted with a heat source, the utilization rate of the heat source can be improved, and the copper mud with better drying quality can be obtained; however, the rotating through shaft needs a power source to drive the rotating, the drier can be installed through the shaft of the drier, the length of the rotating shaft in actual production cannot exceed 13m due to the limitation of the material of the rotating shaft and the limitation of the temperature in the drying cylinder, so that the drying yield cannot keep up with the requirement, and the rotating shaft exceeding the range is easy to deform at high temperature and is not durable, so that continuous production cannot be realized.

Detailed Description

As shown in fig. 1 and fig. 2, a three-layer dryer inner cylinder scattering device comprises an inner cylinder 60, a material guide plate 61 is arranged on the inner wall of the inner cylinder 60, a scattering shaft 70 is arranged on the axis of the inner cylinder 60, and the scattering shaft 70 is connected with the wall of the inner cylinder 60 through a support rod 71; the scattering shaft 70 is provided with a material lifting plate 72.

The scattering shaft 70 is fixed on the wall of the inner cylinder 60 of the three-layer dryer through a support rod 71, when the inner cylinder 60 rotates, the scattering shaft 70 is driven to rotate, and the material raising plate 72 arranged on the scattering shaft 70 scatters the dried materials falling from the wall of the inner cylinder; the power devices do not need to be arranged at the two ends of the scattering shaft to drive the scattering shaft to rotate, so that the energy consumption is reduced.

As shown in fig. 2, the breaking shaft 70 is arranged in a segment in the inner cylinder 60 and is connected with the wall of the inner cylinder 60 through a support rod 71.

Through setting up the axle 70 of breaing up of segmentation, can will break up the axle at reasonable within range and prolong to the longest, thereby increase the length of three-layer drying-machine inner tube and increase drying output to improve the whole productivity of production line, increase economic profit, be greater than the productivity benefit of a logical axle far away.

At least three support rods 71 are arranged on each section of breaking shaft 70.
