Abstract
The utility model discloses a prefilter with a filter element made of polyethylene foam material. The prefilter mainly comprises a filter cover, a filter barrel, the filter element and a filter drain valve. The prefilter takes the polyethylene foam material to make the filter element which is installed on a connecting piece set on the filter cover. The material of the filter element has big specific surface area, high mechanical strength, good chemical stability, strong wettability and permeability to water, and excellent filtration and separation functions, and is low in cost and easy to wash and can be used repeatedly. The prefilter is simple in structure and convenient to dismantle and assemble, and the filter element can be recovered or replaced at all times according to service conditions. The material of the filter element can be used as a substitute for a prefilter which takes a stainless steel filter screen or a nylon filter screen as a filter element.
Description
Technical field
The utility model relates to the water treatment field of purification, is specifically related to a kind of fore filter take polyvinyl alcohol foam material as filter core.
Background technology
Along with progress and development, the living standard of society improves constantly, people are also more and more higher to the requirement of domestic water, therefore different types of water purification equipment and being widely used, and fore filter is exactly one of equipment indispensable in the water supply network.Its Main Function is to remove the granule foreigns such as the precipitated impurities that produces in city and the residential quarter water supply network, bacterium, microorganism remains, iron rust, husky mud; avoid human body and skin to come to harm; and to downstream line, hot-water heating, boiler, central air-conditioning, water heater, washing machine, dish-washing machine, coffee machine, high-grade tap, spray shower head, and other appliance water (water purifier, water purification machine, water softening device) play positive protective effect, greatly prolong the service life of described follow-up equipment.All fore filter must be installed at German fore filter law-making stipulation later owned building in 1988, so fore filter is used at European ﹠ American Market extremely extensive.Fore filter is the jinx of water pollution once again, is a kind of reliable device for filtering impurities.
The filter core of fore filter mostly adopts stainless steel filtering net, nylon leaching net, does not also have so far other isolated by filtration material to be used for the filter core of fore filter.The inside of polyvinyl alcohol foam material has cross-linked structure, the more uniform micropore in densification and aperture is arranged, the material specific area is large, mechanical strength is high, and chemical stability is good, and is strong to wellability and the permeability of water, possesses good isolated by filtration function, can be used as a kind of Novel filtration parting material of water field of purification since its cost of material is low, be easy to reuse, be expected to become the isolated by filtration material that the utmost point in the purifying water process industry has popularizing application prospect.
The utility model content
The purpose of this utility model provides a kind of fore filter take polyvinyl alcohol foam material as filter core, this filtration device structure is simple, easy accessibility, the polyvinyl alcohol foam material filter core can recover at any time or changes according to operating position, can be used as the substitute take stainless steel filtering net, nylon leaching net as the fore filter filter core.
The technical scheme that realizes the utility model purpose is: a kind of polyvinyl alcohol foam material filter core fore filter comprises lid of filter, filter cylinder, filter element, filter tapping valve; Described fore filter is take polyvinyl alcohol foam material as filter core, and described filter element is installed on the attaching parts of lid of filter setting.
Described filter element is made of the tubular polyvinyl alcohol foam material filter core of an end opening one end closing structure and the inner support bushing pipe that has a porous.
The attaching parts that arrange on the described filter filter cover body are comprised of tubular screw rod and the interior screw thread nut of male thread in the band.
The beneficial effect that the utility model produces is: as the fore filter filter core, provide a kind of novel material for core with polyvinyl alcohol foam material; This filter core specific area is large, and mechanical strength is high, and chemical stability is good, and is strong to wellability and the permeability of water, possesses good isolated by filtration function, and the cost of material is low, be easy to clean and reuse; This fore filter is simple in structure, easy accessibility, and filter core can be changed at any time.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
For understanding that can be detailed to the utility model, also be described in further detail by reference to the accompanying drawings according to embodiment.As shown in Figure 1, the utility model mainly comprises lid of filter 1, filter cylinder 2, filter element 3, filter tapping valve 4; Wherein filter element 3 is made of the tubular polyvinyl alcohol foam material filter core 3-1 of an end opening one end closing structure and the inner support bushing pipe 3-2 that has a porous; The tubular screw rod 6 that is provided with on the filter filter cover body 1 by male thread in the band forms attaching parts with interior screw thread nut 7, tubular polyvinyl alcohol foam material filter core 3-1 and inner support bushing pipe 3-2 can be connected and fixed on the filter filter cover body 1; Filter filter cover body 1 is provided with water inlet 8 and delivery port 9; Filter cylinder 2 bottoms are provided with tapping valve 4; Filter filter cover body 1 interconnects by screw thread 5 with filter cylinder 2.
During installation, at first the interior screwed connection of tubular screw rod 6 on inner support bushing pipe 3-2 and the filter filter cover body 1 is fixed, again polyvinyl alcohol foam material filter core 3-1 is placed on the inner support bushing pipe 3-2, then is connected with the male thread of tubular screw rod 6 with interior screw thread nut 7 polyvinyl alcohol foam material filter core 3-1 is fixed; At last filter filter cover body 1 and filter cylinder 2 are connected and fixed by screw thread 5.
During use, the running water household water pipe is connected with the water inlet 8 of filter, the delivery port 9 of filter is connected with indoor waterpipe and equipment.When running water enters fore filter by water inlet 8, at first enter in the filter cylinder 2, running water filters by delivery port 9 through filter filter core 3 and flows out under the effect of hydraulic pressure; After long-time the use, in filter cylinder 2, reach filter element 3 outer walls and have Impurity deposition accumulation in the pipeline, can open the manual control handle 11 of filter tapping valve 4 this moment, and current can be gone out the deposit in the filter through the leakage fluid dram 10 of tapping valve 4.
