Problems solved by technology

[0003] The existing maintenance and cleaning method is to manually enter the interior of the hydrocyclone and use electric picks or pneumatic picks to clean the accumulated material. The inventor found that when cleaning the accumulated material inside the hydrocyclone in this way, due to the narrow working space of the hydrocyclone , It is very inconvenient and inflexible for personnel to enter the internal movement and maintenance process, and the inside of the hydrocyclone is humid, the temperature is high, and the accumulated material contains a large amount of lye, which brings a very large safety risk to the maintenance personnel.
At the same time, such a cleaning method has a large workload and the cleaning effect is not good.

Embodiment 1

[0030] Attached below figure 1 The flushing device disclosed in this embodiment is further described;

[0031] Refer to attached figure 1 As shown, the hydrocyclone accumulation flushing device includes an annular pipeline 5 arranged inside the hydrocyclone 6, and a plurality of nozzles 7 are arranged at the bottom of the annular pipeline 5. In this embodiment, 8 nozzles are set, and 8 nozzles 7 are evenly spaced along the circular pipeline 5 ring direction.

[0032] The nozzle 7 is arranged obliquely, and the nozzle 7 is arranged obliquely downward from the inner side of the annular pipeline 5 to the outer side, and the water outlet of the nozzle 7 is opposite to the bottom wall of the hydrocyclone 6, so that an inclined angle is formed between the nozzle 7 and the inner wall of the hydrocyclone 6 , can improve the effect of hydrocyclone flushing.

[0033] The annular pipeline 5 is provided with a night inlet to communicate with the pipeline 3 , the pipeline 3 is communica...

Abstract

The invention discloses a hydrocyclone accumulated-material flushing device. The hydrocyclone accumulated-material flushing device comprises an annular pipeline arranged in a hydrocyclone, a pluralityof spray nozzles are arranged at the bottom of the annular pipeline, the nozzles are arranged obliquely, the annular pipeline communicates with a mother liquid pump through a pipeline, the mother liquid pump is connected with a mother liquid tank, and a stop valve is arranged on the pipeline. The flushing device can automatically flush accumulated materials in the hydrocyclone, the cleaning workload of the hydrocyclone is reduced, and the safety risk of personnel entering the interior of the hydrocyclone for cleaning is avoided.

Description

technical field [0001] The disclosure belongs to the technical field of hydrocyclone flushing, and in particular relates to a hydrocyclone accumulation flushing device. Background technique [0002] In the raw grinding process of the alumina plant, the hydrocyclone needs to be checked and cleaned regularly due to the frequent shutdown of the hydrocyclone due to material accumulation. [0003] The existing maintenance and cleaning method is to manually enter the interior of the hydrocyclone and use electric picks or air picks to clean the accumulated material. The inventors found that when cleaning the accumulated material inside the hydrocyclone in this way, due to the narrow working space of the hydrocyclone , It is very inconvenient and inflexible for personnel to enter the internal movement and maintenance process, and the interior of the hydrocyclone is humid, the temperature is high, and the accumulated material contains a large amount of lye, which brings a very large ...
