Abstract
The utility model relates to a vertical pan filter main shaft sealing structure. The vertical pan filter main shaft sealing structure is characterized in that a shaft sleeve is composed of an upper shaft sleeve and a lower shaft sleeve; the upper shaft sleeve and the lower shaft sleeve are fastened on a main shaft through connecting bolts; a packing case body is fixed on a positioning plate; the positioning plate is welded on a baffle plate; and a packing is equipped inside the packing case body and pressed by a packing pressure plate. The shaft sleeve, the packing pressure plate, the packing case body and the positioning plate are respectively composed of two components which are the same to each other. Thus, the shaft sleeve, the packing pressure plate, the packing case body and the positioning plate are convenient to dismount and replace. The structure which solves the problem that an adverse seal between the vertical pan filter main shaft and a hopper results in serious material leakages improves the hygienic conditions of equipments and operation environments, enhances the safety and stability of equipment operations, and lowers the work intensity of operators. Furthermore, the structure increases the production power of a vertical pan filter and reduces the loads on corresponding overflow pumps and overflow groove speed reducers, etc. in a filter system. Notably, the structure alleviates material leakages in the vertical pan filter and has great energy-saving and consumption-reducing effects.
Description
Technical field
The utility model belongs to the alumina producing apparatus field, is specifically related to a kind of main shaft two ends of vertical-disk filter and the structure of cell body sealing.
Background technique
Vertical-disk filter is the visual plant in the alumina producing, is responsible for the aluminum hydroxide slurry of seed decomposition process is separated, so that corresponding crystal seed and mother liquor to be provided.When existing deficiency to cause the liquid level raising of hopper owing to rotation position between vertical-disk filter main shaft and the hopper body, spillway discharge can increase greatly, thereby has increased the load of flood pump and bypass channel at present; Simultaneously cause slip to leak outside because of filter hopper body sealed at both ends weak effect, the material that leaks out causes and can't carry out normal filter operating difficulties, influence environmental hygiene, the increase labor intensity of operating personnel, and also there is the potential safety hazard of snare in the energy consumption height.
The model utility content
The utility model is to the deficiency of present vertical-disk filter main shaft sealing construction; A kind of novel sealing structure unit is provided; Prevent between vertical-disk filter main shaft and the hopper that poor sealing causes that Lou material (overflow) is big; Improve the vertical-disk filter production capacity, the load of corresponding flood pump and bypass channel speed reducer in the minimizing system is to reach energy-saving and cost-reducing purpose.
The utility model technology implementation scheme is following:
Remove the blocking material ring on outside material-receiving bucket in vertical-disk filter two ends and the main shaft; New wear-resisting steel bushing is installed in former blocking material ring position; The new sealed case of installation on former connect material head and cell body; The graphite packing is installed between wear-resisting steel bushing and sealed case then and is compressed so that reach sealing effect the leakage of minimizing slip with pressure ring.Disassembling, assembling and replacing for ease, wear-resisting steel bushing and sealed case assemble by the two halves of symmetry.
Structure characteristic is: axle sleeve 1 is fastened on the main shaft 6 through attachment bolt 10 by Upper shaft sleeve 8 and Lower shaft sleeve 9; Packing casing 3 is fixed on the positioning plate 4, and positioning plate 4 is welded on the baffle plate 5, and packing 7 is installed in the packing casing 3, is compressed by packing pressing plate 2; Axle sleeve 1, packing pressing plate 2, packing casing 3, positioning plate 4 are made up of the part that two halves are identical separately respectively.
The technological merit of the utility model is:
Solved not only that poor sealing causes the Lou big problem of material between vertical-disk filter main shaft and the hopper; Equipment and operating environment health have been improved; Operation of equipment safety and stability have been improved; Alleviate labor intensity of operating personnel, improved the vertical-disk filter production capacity, reduced equipment load such as corresponding flood pump and bypass channel speed reducer in the filter system; The aspect of dismounting simultaneously helps the maintenance and the maintenance of this part.Through facts have proved of nearly one-year age, the utility model leaks material to reducing vertical-disk filter, energy conservation and consumption reduction effects is remarkable.
Description of drawings
Fig. 1 is a vertical-disk filter main shaft sealed at both ends structural representation.
Fig. 2 is the sealing axle sleeve structural representation.
Among the figure, 1-axle sleeve, 2-packing pressing plate, 3-packing casing, 4-positioning plate, 5-baffle plate, 6-main shaft, 7-packing, 8-Upper shaft sleeve, 9-Lower shaft sleeve, 10-attachment bolt.
Embodiment
Below in conjunction with accompanying drawing and embodiment model utility is further specified.
Axle sleeve 1 among Fig. 1 is fastened on the main shaft 6 through attachment bolt 10 by Upper shaft sleeve among Fig. 28 and Lower shaft sleeve 9; Packing pressing plate 2 among Fig. 1, packing casing 3, positioning plate 4 are made up of the part that two halves are identical separately respectively; Wherein positioning plate 4 is welded on the baffle plate 5, and packing casing 3 uses bolt to be affixed on the positioning plate 4, behind the installation packing 7; Suitably compress packing by packing pressing plate 2 through bolt, effectively stop the leakage of material in the vertical-disk filter cell body.After guaranteeing the perpendicularity and concentricity of positioning plate 4 and main shaft 6 during installation, could guarantee the location of packing casing 3.
