Abstract
The invention discloses a water balance regulating method for a filter, which relates to water balance of a rotary-table-type vacuum filter. According to the invention, a pipeline is added on a first washing section water outlet on the filter and is connected to a second washing section water inlet pipe; a pipeline is added at a second washing section water outlet and is connected to a first washing water pipe, thus the first washing water pipe is communicated with a second washing water pipe; the added pipelines is respectively and additionally provided with a butterfly valve; and when a system operates, according to the water quantity of the filter system, the butterfly valves on the added communicated pipes are regulated, namely, first washing water quantity and second washing water quantity are regulated, thus the filtering system achieves water balance. The method provided by the invention is simple, is convenient and simple to operate, can well regulate the water balance of the filter system and a rear system of the rotary-table-type vacuum filter, can improve the system to run stably for a long cycle, and is suitable for manufacturers using the rotary-table-type vacuum filter.
Description
[technical field]
The present invention relates to separate, relate in particular to filtration, relate in particular to the water balance of turntable type vacuum filter.
[background technology]
Filter is a kind of dissolubility difference of utilizing material, a kind of plant equipment that liquid and the solid that is insoluble to liquid are separated.Be widely used in industries such as chemical industry, oil, pharmacy, light industry, food, ore dressing, coal and water treatment.In Chemical Manufacture, filter not only will also will be considered the water balance of filter system to Separation of Solid and Liquid.If the water of system is uneven, can make system unstable, cause the whole production device to stop when serious; Also can make consumption of raw materials increase, production cost raising, generation large amount of sewage etc. influence system's operation.
In the Chinese patent database; The application part that relates to filter is few; Like ZL No. 02112753.0 " rotary vacuum disk fiter ", ZL No. 200920198884.0 " the turntable filters of band air purge deslagging " etc.; But up to now, do not see to relate to and regulate the isorrheic technical scheme of turntable type filter.
[summary of the invention]
The object of the present invention is to provide the method for the isorrheic adjusting of a kind of turntable type filter, solve the water balance of filter system effectively.
Be used for the turntable type vacuum filter that crystal filters; Production procedure is that material is put into filter cloth and carried out vacuum filtration; Filtrating is passed filter cloth, and filter cake is stayed on the filter cloth, and filter cake gets into first washing section (being called for short washes) successively and second washing section (being called for short two washes) is used water washing; Discharging then obtains crystal product; Then clean filter cloth, carry out putting into of next group material once more, so circulation with clear water.
The inventor is through repeatedly experimental study; Found the isorrheic technology of adjusting turntable type vacuum filter; Promptly setting up a pipeline at the section of the washing delivery port on the filter is connected on two section of the washing water inlet pipes; Set up a pipeline at two section of washing delivery ports and be connected on the wash water pipe, make a wash water pipe and two wash water pipe UNICOMs on the pipeline of setting up, respectively to add a butterfly valve; When system moves, regulate the butterfly valve on the cross over pipe of setting up according to the water yield of filter system, just regulate a leaching requirement and two leaching requirements, making is the filtration system weighing apparatus that is up to the standard.
In the said method, the pipeline of setting up and, two wash water pipe materials are identical; The diameter of two pipelines setting up is identical, and two valve models of setting up are identical.
The inventive method is simple, and is easy to operate simple, can regulate the water balance of the filtration system and the back system of turntable type vacuum filter well, can promote system's long-period stable operation.Be applicable to the producer that uses the turntable type vacuum filter.
Description of drawings
Fig. 1 is the system schematic of original filter, and Fig. 2 is the system schematic of the inventive method.
Among the figure, 1 is the vacuum filtration section, and 2 is first washing section, and 3 is second washing section, and 4 is unloading part, and 5 is the filter cloth washing section, and 6 are newly-increased pipeline, and 7 are newly-increased butterfly valve.
[specific embodiment]
Embodiment:
Certain factory's ardealite system ammonium sulfate device filters workshop section and adopts the present invention to regulate the water balance of the filtration system and the back system of its turntable type vacuum filter.
Set up a pipeline at the section of the washing delivery port on the filter and be connected on two section of the washing water inlet pipes, set up a pipeline at two section of washing delivery ports and be connected on the wash water pipe, make a wash water pipe and two wash water pipe UNICOMs on the pipeline of setting up, respectively to add a butterfly valve; When system moves, regulate the butterfly valve on the cross over pipe of setting up according to the water yield of filter system, just regulate a leaching requirement and two leaching requirements, making is the filtration system weighing apparatus that is up to the standard.Two pipe diameters setting up are DN50, and the model of two butterfly valves setting up is D371F-16RLDN50.
Adopt after this method, realized the water balance of filter, filtration system stable operation.
Claims (2)
1. the method for the isorrheic adjusting of filter; It is characterized in that setting up a pipeline in the first washing section wash water pipe exit position on the turntable type vacuum filter is connected on the second washing section wash water pipe; Setting up a pipeline in the second washing section wash water pipe exit position is connected on the first washing section wash water pipe; Make the wash water pipe UNICOM of the wash water pipe and second washing section of the washing section of winning, a valve respectively is installed on the pipeline of setting up; When system moves, regulate the valve on the cross over pipe according to the water yield of filter system, just regulate the leaching requirement of first washing section and the leaching requirement of second washing section, making is the filtration system weighing apparatus that is up to the standard.
2. according to the described method of claim 1, it is characterized in that the said pipeline of setting up is identical with one, two wash water pipe materials; The diameter of two pipelines setting up is identical, and two valve models of setting up are identical.
