Abstract
The present invention relates to a configuring method for a red mud filtering workshop in an alumina production line. Primary appliances including a feedstuff tank, a feedstuff pump, a vacuum drum filter, a vacuum receiver tank, a water cooler, a vacuum pump, a liquid seal tank, a filtrate tank, a filtrate pump, etc. are configured in the manner that a workshop is divided into three layers; the tanks and the pumps are arranged on a (+/-)0.000 plane surface, a red mud conveying screw is arranged on a middle plane surface, and a filtering machine is arranged on the upper plane surface. The present invention is characterized in that (1) the height of an upright post in the middle of a factory building is reduced so that the upright post does not reach a roof; (2) a single-beam electric crane or a bridge crane is used in a hoisting facility; (3) a power supply cable of the hoisting facility is an alkali preventing sliding contact line. After the method of the present invention is used, the crane has stable work performance so that the crane does not need to be overhauled frequently, the overhauling coverage area of the crane includes the entire operation plane surface of the filtering machine so that a wide overhauling surface is provided, and the entire wide top plane surface is favorable to workers' operation so that the problem that the top plane surface of the red mud filtering workshop has difficulty in being overhauled is thoroughly solved.
Description
Technical field
The present invention is relevant with alumina producing, and is particularly relevant with the filtering red mud of alumina production line, furthermore, relevant with the configuration in filtering red mud workshop.
Background technology
In the production process of aluminium oxide, filtering red mud is an important procedure.Because filter cake moisture content, the alkali content of technological requirement filtering red mud reduce as far as possible, with the environmental requirement of satisfying red mud dump and reclaim alkali.The capital equipment in filtering red mud workshop has trough, feed pump, vacuum-type drum filter, vacuum to be subjected to liquid bath, water cooler, vavuum pump, liquid seal trough, filtrate receiver, filtrate pump etc.The traditional configuration of these equipment is: the configuration in workshop divides three layers.Groove, pump are arranged on ± 0.000 plane, and the red mud conveyor screw is arranged on mid-plane, and filter is arranged on the plane.Column in the middle of the factory building reaches the roof always, red mud filter maintenance and when changing filter cloth be 3 tons electric block work by 4 lifting capacities.Through the production practices check, find that there is following shortcoming in this maintenance scheme:
Require 4 electric blocks energy usefulness simultaneously when (1) overhauling, and this workshop alkali steam is big, electric block brings very big inconvenience usually because steam corrosion causes damage to maintenance;
(2) when slinging the maintenance parts heavier, two electric block parallel turns are very difficult, almost can not turn, and because pillar stretches to the roof, ground controlling inconvenience always;
(3) vacuum that is provided with on this plane can't be overhauled by liquid bath, water cooler and pipe fitting thereof.
Summary of the invention
The objective of the invention is to propose a kind of collocation method of new filtering red mud workshop, by problem with thorough solution filtering red mud workshop capital equipment operation planar maintenance difficulty.
Main contents of the present invention are as follows:
Be subjected to configurations such as liquid bath, water cooler, vavuum pump, liquid seal trough, filtrate receiver, filtrate pump to be in filtering red mud workshop capital equipment trough, feed pump, vacuum-type drum filter, vacuum: the configuration in workshop divides 3 layers, groove, pump are arranged on ± 0.000 plane, the red mud conveyor screw is arranged on mid-plane, and filter is arranged on the plane.On this basis, characteristics of the present invention are:
(1) reduce the middle column height of factory building, make it not reach the roof, plane, whole top seems openr;
(2) the lifting facility uses electric single beam crane or bridge crane;
(3) service cable of lifting facility adopts the alkali prevention trolley.
Normally used lifting facility is a 3t electric single beam crane or bridge crane.
Adopt the foregoing invention content, following advantage is arranged: (1) crane work stable performance can not resemble and use electric block because caustic corrosion and often overhauling; (2) the maintenance coverage of crane is whole filter operation planar, overhauls widely, each can be overhauled object and hang desirable maintenance and step into row maintenance, comprises the maintenance of vacuum groove, water cooler and is installed in the replacing that vacuum is subjected to pipeline on liquid bath, the water cooler; (3) plane, whole top seems openr, helps workman's operation, has solved the problem of top layer plane, filtering red mud workshop maintenance difficulty up hill and dale.
Description of drawings
Accompanying drawing 1 is the disposition-plan in traditional filtering red mud workshop, and accompanying drawing 2 is the disposition-plan in filtering red mud of the present invention workshop.1 is electric block among the figure, and 2 is rotary drum filter, and 3 for vacuum is subjected to liquid bath, and 4 is water cooler, and 5 is crane.
The specific embodiment
Embodiment: certain factory's filtering red mud workshop configuration as shown in Figure 1, the configuration of equipment divides three layers: groove, pump are arranged on ± 0.000 plane, the red mud conveyor screw is arranged on mid-plane, filter is arranged on the plane, the factory building column reaches the roof always, red mud filter maintenance and when changing filter cloth be 3 tons electric block work by 4 lifting capacities.
Through adopting collocation method transformation of the present invention, dispose as shown in Figure 2, the column height in the middle of the factory building reduces, and till the red mud filter configuration plane, makes it not reach the roof; The lifting facility uses 1 3t electric single beam crane; The service cable of lifting facility adopts the alkali prevention trolley.
The configuration of improved filtering red mud workshop has solved the difficult problem of top layer plane, filtering red mud workshop maintenance up hill and dale.
Claims (2)
- The collocation method in filtering red mud workshop in 1 one kinds of alumina production lines, capital equipment trough, feed pump, vacuum-type drum filter, vacuum are subjected to configurations such as liquid bath, water cooler, vavuum pump, liquid seal trough, filtrate receiver, filtrate pump to be: the configuration in workshop divides 3 layers, groove, pump are arranged on ± 0.000 plane, the red mud conveyor screw is arranged on mid-plane, filter is arranged on the plane, feature of the present invention comprises: (1) reduces the column height in the middle of the factory building, makes it not reach the roof; (2) the lifting facility uses electric single beam crane or bridge crane; (3) service cable of lifting facility adopts the alkali prevention trolley.
- The collocation method in 2 filtering red mud as claimed in claim 1 workshops is characterized in that described lifting facility is a 3t electric single beam crane or bridge crane.
