Abstract
It is desirable to provide a kind of vertical filter cloth of disc filter cleaning method, comprise the following steps: A, closedown charging aperture, open discharge gate, close vacuum extractor, discharge the clout within filter, control the card low-speed running of vertical disk filter simultaneously；Filter cloth is rinsed by B, use hot water, and the time is 34 minutes；C, closedown discharge gate, open vacuum extractor, then proceedes to use hot water injection 56 minutes；D, closedown hot water, open discharge gate, discharged by remaining water.The method overcomes prior art to wash cloth the defect of time length, has easy and simple to handle, the feature of efficient quick.
Description
Technical field
The present invention relates to equipment filter cloth and clean field, be specifically related to a kind of vertical filter cloth of disc filter cleaning method.
Background technology
The filter cloth of vertical disk filter is in use rhythmic, and the use cycle is about 45 days, in order to ensure
Filter cloth normally used within the cycle, and the vertical disk filter hot water run must be washed cloth 1-2 time, by filter cloth by the most each machine-team
Upper oxalates wash clean.But, in the operation process that washes cloth, there is the water temperature that washes cloth, the mode that washes cloth inconsistent, cause in each machine-team
The time length that washes cloth (the separate unit time of washing cloth is about 20 minutes), the device standby time is long, affects manufacturing parameter and Liquid level, and
Too much water enters flow process and will result in steam consumption for evaporation increase.
Summary of the invention
It is desirable to provide a kind of vertical filter cloth of disc filter cleaning method, the method overcomes prior art to wash cloth the time
Long defect, has easy and simple to handle, the feature of efficient quick.
Technical scheme is as follows:
A kind of vertical filter cloth of disc filter cleaning method, comprises the following steps:
A, closedown charging aperture, open discharge gate, close vacuum extractor, discharge the clout within filter, control vertical plate simultaneously
The card low-speed running of formula filter；
Filter cloth is rinsed by B, use hot water, and the time is 3-4 minute；
C, closedown discharge gate, open vacuum extractor, then proceedes to use hot water injection 5-6 minute；
D, closedown hot water, open discharge gate, discharged by remaining water.
Preferably, described hot water temperature is 95 DEG C-100 DEG C.
Preferably, in described step C, vacuum degree control is-0.01 to-0.013Mpa.
Cleaning method of the present invention uses hot water to clean the combination cleaned with vacuum state hot water, completes slightly washing and essence of filter cloth
Wash；Slightly washing the oxalates etc. by filter cloth surface bonds to wash out, fine purifiation, by the negative pressure of vacuum system, removes filter cloth hole further
Interior microgranule and oxalates, and shortening washes cloth the time further；Use this cleaning method, originally about 20 minutes wash cloth the time,
Shorten to 8-10 minute, decrease the consumption of water resource, and cleaning performance is more preferable, extends the service life of filter cloth.
Detailed description of the invention
The present invention is illustrated below in conjunction with embodiment.
Embodiment 1
The vertical filter cloth of disc filter cleaning method that the present embodiment provides, comprises the following steps:
A, closedown charging aperture, open discharge gate, close vacuum extractor, discharge the clout within filter, control vertical plate simultaneously
The card low-speed running of formula filter；
Filter cloth is rinsed by B, use hot water, and the time is 3-4 minute；
C, closedown discharge gate, open vacuum extractor, then proceedes to use hot water injection 5-6 minute；
D, closedown hot water, open discharge gate, discharged by remaining water；
Wherein, described hot water temperature is 95 DEG C, and in step C, vacuum degree control is at-0.013Mpa.
