Description
Technical Field
The invention relates to the technical field of water treatment and washing machines, in particular to a filter element and a washing machine applying the filter element.
Background
Whether the existing washing machine is a roller washing machine or a pulsator washing machine, whether the existing washing machine has the function of automatically adding laundry detergent or not, the situation that the clothes cannot be really rinsed completely according to the designed program and the laundry detergent is remained too much often exists in the washing and rinsing time set by the existing automatic control program. The main reason is that the addition amount of the laundry detergent cannot be determined according to the pollutants carried by the clothes before washing, and the rinsing time cannot be determined according to the residual amount of the laundry detergent of the clothes after rinsing.
The manual addition of washing powder or laundry detergent is often inaccurate and can be added excessively; the washing machine with the automatic laundry detergent adding function adds the laundry detergent with a corresponding amount according to the weight, and if the stain content of clothes is not high, the problem of excessive laundry detergent adding exists, so that the laundry detergent remains too much after washing; or because the effective components of the laundry detergents of different brands are different, the problem of excessive addition of the laundry detergents also exists. The main reason for this problem is the surfactant substances usually contained in detergents or washing powders, which are too much residual in laundry detergents, which are uncomfortable to wear if the residual is too much, and cause certain damage or allergic reaction to human skin if the residual is too much.
The existing washing machine is provided with a coarse filtering device at the water inlet of the washing machine or at the bottom of the washing machine, and can only filter and intercept larger particle suspended matters such as thread scraps and the like in inlet water or washing and rinsing water, but can not remove possible overhigh laundry liquid residue in the rinsed clothes.
The relatively fine water filtering device of the washing machine adopts an ultrafiltration mode to perform fine filtration, and can partially filter the residual laundry detergent attached to the online scraps in a practical effect, but the effect is limited.
In the prior art, an additional waste water barrel connected with a washing machine is used for collecting washing and rinsing waste water, a flocculating agent and a coagulant are respectively added, precipitates after reaction are discharged out of the waste water barrel, and supernatant is pumped back into the washing machine by an additional electric water pump to be used as supplementary water for rinsing. The residual effect of the laundry detergent is better, but the cost is increased greatly, the floor area of the washing machine is increased, the structure is complex, and the addition of the flocculating agent and the flocculating agent brings difficulty in operation.
In view of the above, the present invention is particularly proposed.

Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Example 1
In this embodiment, a filter element is provided, the filter element includes polyaluminium salt or polyacrylamide encapsulated in a filter shell, and a slow-release agent component, and the filter element is disposed in a circulation water path of a washing machine to remove redundant anionic surfactant in a water body.
In the scheme, the main component of the conventional laundry detergent or washing powder is an anionic surfactant, namely sodium alkyl benzene sulfonate. Considering the space limitation of the washing machine and the stability and the economy of the filter element removing effect, the slow-release filter material based on the polyaluminium salt is selected, and the mechanism of removing the anionic surfactant is as follows: al formed by hydrolysis-polymerization of polyaluminium13O4(OH)24 7+From a tetragonally coordinated aluminium AlO4Is formed by combining an oxygen bridge with 12 surrounding six-coordination octahedral aluminum. The anion surfactant is electrically neutralized, destabilized, adsorbed and bridged to generate particle floccules for removal; in order to ensure the long-term removal effect of the filter element on the anionic surfactant, the polyaluminium salt mixed polymer material and the sustained-release agent are made into the sustained-release filter material. When the rinsing water containing the anionic surfactant flows through the filter element and contacts with the filter material, a small part of polyaluminium salt is slowly dissolved into the water and then forms hydrolysis-the polymer is bound to anionic surfactant in the rinse water and eventually trapped as flocs; meanwhile, the slow-release filter material prepared by adding the high-molecular coagulant, namely polyacrylamide, is considered, so that the bridging effect among the flocculated precipitates is strengthened, larger precipitates are formed, and the precipitates are conveniently and quickly filtered and intercepted in a short time.
In the embodiment, the active ingredient for removing the surfactant in the filter element is polyaluminium salt or polyacrylamide, preferably polyaluminium salt, and the content ratio of the slow release agent to the active ingredient in the filter element is 30-40: 60-70, preferably 33: 67; the slow release agent is one or more of porous polystyrene, cellulose phthalate, polyacrylate and sodium polystyrene sulfonate, and is preferably porous polystyrene. When the content ratio of the slow release agent to the effective components in the filter element is 30-40: 60-70, the filter element has a better slow release effect.
In this embodiment, a third detection mechanism certified by CMA detects the effect of the filter element on removing the surfactant, and the filter element has a LAS (surfactant) removal rate as high as 89.4% by using the standard of GB 7494-.
In this example, a multi-cycle experiment was used to verify the sustained release treatment effect of the surfactant, the experimental method being as follows:
1. dissolving 10g of laundry detergent into 10L of water in each period, and sealing 80g of slow-release filter material into a filter element for filtering;
2. filtration was performed for 10min per cycle for a total of 100 cycles.
The content of the surfactant in the filtered water sample of the selected period is detected, the used tester is a HANNA anionic surfactant tester, and the detection results are shown in Table 1 and FIG. 9:
table 1 validation of the multi-cycle test on the filter element of example 1
As shown in table 1 and fig. 9, after the sustained-release filter material achieves the highest surfactant removal effect in the first two periods, the surfactant removal effect can be stabilized at a removal rate of 23-40% in a longer period, so as to achieve the sustained-release effect of the active ingredients.
Comparative example 1
In this embodiment, no slow-release agent component is added to the filter element, and the polyaluminium salt or polyacrylamide is simply used as the filter material, and the experimental method and the detection method described in embodiment 1 are adopted, and the detection results are shown in table 2 and fig. 10:
TABLE 2 validation results of the multiple cycle test on the filter element of comparative example 1
| Period of time | Configuring the surface activity content (mg/L) of a washing water sample | Water sample surface activity content (mg/L) after circulation | Throughput of treatment |
| 1st | 79 | 18.6 | 76.45％ |
| 2nd | 83 | 72.2 | 13.01％ |
| 3th | 81 | 81 | 0.00％ |
| 5th | 78 | 78 | 0.00％ |
As shown in table 2 and fig. 10, in the filter material from the third cycle, the active ingredients are completely dissolved with the water flow, the effect of removing the surface active substances is lost, and the slow release effect of the active ingredients cannot be achieved.
