Description
Technical field
The present invention relates to filter plant technical fields, and in particular to a kind of Novel disc-type diatomite filter and useless diatom
The dry discharge method of soil.
Background technology
Currently, filter plant is widely used to the necks such as water process, food, brewing, beverage, oils processing, chemical industry synthesis
Domain, filter plant mainly have disc-type diatomite filter, candle stick type diatomaceous earth filter etc. several, wherein disc-type diatomite
Filter with its content be lost less, filter effect is higher the advantages that and as brewing, drink enterprise preferred filter plant, but
That there is also filter process the degree of automation is low for existing disc-type diatomite filter, filter efficiency is low, filtering is of high cost, is not easy
The defects of cleaning, be seriously polluted.
Wherein, easy cleaning and seriously polluted reason are not primarily due to disc-type diatomite filter, existing disc type
Diatomite filter handles waste diatomite by the way of wet row.The diatomaceous process of the wet waste discharge of disc-type diatomite filter is such as
Under, after the completion of the filtering of disc-type diatomite filter, air bleeding valve is first opened, remaining tank liquid is passed through under filtering tank with pump
The valve in portion is extracted into raffinate filtering tank, is then filtered by raffinate filtering table, and filtered clear liquid is from the bottom of residual night filtering tank
Portion is discharged.The diatomite on filtering table is just remained after determining that the residual liquid in main filtering tank all exhausts, in main filtering tank and is given up
At this moment object impurity opens the blowdown butterfly valve of the sewage draining exit of main filtering tank lower part, then starts electric rotating machine, pass through coupling fluid-structure
Device and belt drive main shaft, filter disc and soil-discharging device rotation, to control the rotary speed of filter disc, open simultaneously cleaning penstock,
Ejected wash water rushes the diatomite and impurity that cleaning pipe spray is rushed on each filter disc by the spray in filtering tank, and filtering disc spins are by rotation
Centrifugation force effect gets rid of diatomite and impurity, and the mixed flow of diatomite and water is good, is easy to exhaust from filter disc, diatomite
It is driven from the blowdown butterfly valve of sewage draining exit and is discharged by the rotation of diatomite soil-discharging device again with the mixture of water, diatomite is discharged into
It on ground, is flowed away by sewer, the external world may be flowed to, cause environmental pollution；The wet row of waste diatomite easily causes sewer stifled
Plug or ground pollution, diatomite is more difficult after being discharged to nature.
