Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model discloses a system for wash folding filter core of big flux of production demineralized water, as shown in fig. 1, including filter core wash bowl 1, filter core washing liquid case 2, self priming pump 3, filter core wash bowl 1 is the sealed columnar body of negative pressure, the folding filter core of big flux has been placed in filter core wash bowl 1, the outlet has been seted up at filter core wash bowl 1's top, the water inlet has been seted up to filter core wash bowl 1's bottom, flange joint has wash bowl lid 8 through filter core wash bowl 1's upper portion, wash bowl lid 8 is used for spacing the folding filter core of big flux, and guarantee that filter core wash bowl 1 is in the negative pressure state, the axle center of folding big flux filter core coincides or is parallel with the axle center of filter core wash bowl 1.

Filter core cleaning solution case 2 has seted up washing liquid export and washing liquid entry, the washing liquid export of filter core cleaning solution case 2 passes through washing liquid suction pipeline 4 intercommunication with the water inlet of filter core wash bowl 1, it is 0.03% to hold concentration in the filter core cleaning solution case 2, pH 3's citric acid solution, self priming pump 3 installs on washing liquid suction pipeline 4, self priming pump 3 is used for impressing the washing liquid in filter core cleaning solution case 2 in filter core wash bowl 1, the outlet of filter core wash bowl 1 is linked together through the washing liquid entry of pipeline with filter core cleaning solution case 2, when wasing, at first squeeze filter core wash bowl 1 inner loop 2 hours with citric acid solution into, then soak 1 hour, recirculation 2 hours can, then take out the folding filter core of big flux, dry for later use.

After a certain production unit desalted water station runs, the filter element needs to be replaced every half month for water quality reasons, 12 filter elements are replaced every time, and the consumption of the cartridge filter element, namely the large-flux folding filter element, is very large. The utility model discloses can wash big flux folding filter core for big flux folding filter core reutilization utilizes the utility model discloses soak, wash big flux folding filter core, continue to use after drying, the purchase volume of the filter core that has significantly reduced has reduced manufacturing cost.

Along inner wall a week fixedly connected with filter core brace table 6 of filter core wash bowl 1, filter core brace table 6 is close to the bottom of filter core wash bowl 1, and is located the upside setting of water inlet, has placed the washing liquid on the filter core brace table 6 and has crossed water board 7, and the washing liquid crosses water board 7 level and places, and run through on it and has seted up a plurality of water holes of crossing, and the washing liquid crosses water board 7 and is used for blocking big flux folding filter core, avoids its rocking from top to bottom and washs not thoroughly. Because the folding filter core of big flux is the column, and longer, and need citric acid solution under the effect of self priming pump 3 when wasing the folding filter core of big flux, the folding filter core of big flux of passing from bottom to top, therefore, if do not set up the washing liquid and pass through water board 7, the bottom of the folding filter core of big flux can not wash very easily, so through setting up filter core supporting bench 6 and washing liquid and pass through water board 7 and support the folding filter core of big flux, make the folding filter core card of big flux pass through between water board 7 and washing barrel head 8 at the washing liquid, make the water inlet of filter core wash bowl 1 be located the washing liquid and pass through water board 7 below, then citric acid solution gets into the folding filter core of big flux from the outside after passing through the water hole of water board 7 through the washing liquid, then flow from the center of the folding filter core upper end of big flux, and then wash the folding filter core of big flux.

The washing liquid is crossed and is fixed on the last face of water board 7 and be provided with round filter core arch 5, and the lower extreme that is used for the folding filter core of big flux in the filter core arch 5 stretches into, and filter core arch 5 is used for blocking the folding filter core of big flux, avoids rocking about it, through setting up filter core arch 5 on water board 7 at the washing liquid for in the lower extreme of the folding filter core of big flux stretches into filter core arch 5, avoid rocking about the folding filter core of big flux, influence the cleaning performance.

Install the filter on the pipeline between self priming pump 3 and the filter core wash bowl 1, because the citric acid solution who washs the folding filter core of big flux is cyclic utilization, consequently, the citric acid solution of avoiding mixing impurity passes through washing liquid suction pipeline 4 and gets into filter core wash bowl 1, so on washing liquid suction pipeline 4, and install the filter on the pipeline between self priming pump 3 and the filter core wash bowl 1, the filter filters impurity, guarantee that clean citric acid washing liquid gets into filter core wash bowl 1, the one end that washing liquid suction pipeline 4 stretched into filter core wash bowl 2 is provided with the stagnant water valve.

And a drainage pump is arranged on a pipeline between the drainage outlet of the filter element cleaning cylinder 1 and the cleaning liquid inlet of the filter element cleaning liquid box 2, and is used for pumping out water in the filter element cleaning cylinder 1 and discharging the water into the filter element cleaning liquid box 2. Because the pipeline is longer, in order to guarantee thoroughly the washing to big flux folding filter core, through install the drain pump on the pipeline between filter core wash bowl 1 and filter core cleaning solution case 2, guarantee the velocity of flow of endless citric acid solution, and then accelerate the washing to big flux folding filter core.

The above description is only for the preferred embodiment of the present invention, and should not be construed as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
