Abstract
The utility model relates to a filtering device, in particular to a device for filtering scabs in pipeline conveying liquid in the producing process of alumina. The device is to solve the problem that the grading efficiency is reduced due to the scabs enter a grading system. The utility model aims at providing the device for filtering the scabs in the pipeline conveying liquid. The device comprises a charging opening, a filter box and a discharging opening. A movable filter plate is arranged in the filter box, a movable box cover is arranged at the top part of the filter box, and an access hole is arranged on the wall of the filter box above the movable filter plate. According to different filter media, the device replaces the filter plate with different filtering apertures, so as to effectively filter the scabs mixed in the conveying liquid. The device can observe the conditions in the filter box by the access hole in the filtering process, and can timely open the movable box cover to remove the scabs on the filter plate, so as to improve the conveying capacity of a charging pump and the grading capacity of a whirlcone.
Description
Technical field
The utility model relates to a kind of filter, is specifically related to the device that scabs in the filter pipe conveying liquid in a kind of aluminum oxide production process.
Background technology
Usually all adopt hierarchy system for improving the finished product granularity in the process for making alumina, and the classifying equipoment that adopts mostly adopts the cyclone group, the classification efficiency of requirement is higher, and the cyclone diameter of employing is unsuitable excessive, generally adopts the cyclone of diameter 150mm.And last groove of decomposition or inferior last groove discharging are generally adopted in the charging of cyclone, and the charging stock pump reaches the effect that eddy flow decomposes by the feed pressure of pump.But decomposer particularly blow tank long-time running meeting generation scabs, the irregular piece that scabs is accompanied by the discharging slurries with after being pumped to cyclone, can cause cyclone underflow mouthpiece to stop up, and effect is decomposed in influence greatly, and bigger scabbing can be stopped up the feed pump impeller, influences the conveying capacity of pump.For this reason, need advance on the pipeline of pump to install the filter that scabs additional.
Summary of the invention
To enter hierarchy system and reduce the problem of decomposition efficiency in order to solve to scab, the purpose of this utility model is to provide a kind of filter pipe to carry the device that scabs in the liquid, can effectively filter in the slurries course of conveying mix scab, improve the cyclone classification ability.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of filter pipe is carried the device that scabs in the liquid, comprises charging aperture, Rose Box and discharging opening, and its special character is: be provided with the active filters plate in the described Rose Box.
The filtration tank wall of above-mentioned active filters plate top is provided with inspection opening.
Above-mentioned Rose Box top is provided with removable box cover.
Aperture on the above-mentioned active filters plate is 8～10mm.
Above-mentioned active filters plate is arranged on apart from 2/3rds places, Rose Box bottom.
The diameter of above-mentioned Rose Box is 3～4 times of feed pipe diameter.
Compared with prior art, the beneficial effect of technical solutions of the utility model generation is:
The utility model is changed the different filter of pore size filter according to the difference of filter medium, and effectively filtered fluid is carried scabbing of mixing in the liquid; The utility model can be observed situation in the Rose Box by inspection opening in filter process, in time open scabbing on the removable box cover cleaning filter, has improved the conveying capacity and the cyclone classification ability of feed pump.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
The 1-charging aperture, 2-discharging opening, 3-Rose Box, 4-active filters plate, 5-inspection opening, 6-removable box cover.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is described in detail.
Referring to Fig. 1, the utility model is that a kind of filter pipe is carried the device that scabs in the liquid, is installed between decomposer and the cyclone charging stock pump, and its charging aperture 1 links to each other with the decomposer discharging opening, and discharging opening 2 links to each other with the charging aperture of cyclone charging stock pump.Be provided with active filters plate 4 apart from 2/3rds places, Rose Box bottom in the utility model Rose Box 3, aperture on the active filters plate 4 is 8～10mm, can select the active filters plate in suitable aperture for use according to the difference of filter medium, effectively filter and carry scabbing of mixing in the liquid.
The filtration tank wall of described active filters plate 4 tops is provided with inspection opening 5, and described Rose Box 3 tops are provided with removable box cover 6.In the filter process, can observe the filtration situation that scabs of active filters plate in the Rose Box, in time open removable box cover, improve the conveying capacity of feed pump and the classification efficiency of cyclone active filters plate dismounting cleaning by inspection opening.
The diameter of described Rose Box 3 is 3～4 times of feed pipe diameter, guarantees to carry in the pipeline flow velocity of liquid.
The utility model also can be installed before intermediate temperature drop equipment such as wide-runner plate heat exchanger, spiral-plate heat exchanger feed pipe and use, and has reduced entering scabbing and other foreign material of cooling system, has guaranteed the heat exchange effect of cooling system.
The above only is preferred embodiment of the present utility model, and not in order to restriction the utility model, common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacement all should be included in the protection domain of the present utility model.
