Abstract
The utility model relates to filtration medium with water absorption function, which comprises a plurality of layers of fibre materials and water absorption granules, wherein, the fibre materials are in a multi-layer structure, the fibre materials are covered closely and are distributed with the water absorption granules. When a small quantity of water in filtered oil passes through the filtration medium, the water is absorbed by the fibre materials and the water absorption granules, so as to achieve the purpose of water filtering; when a large quantity of water in filtered oil passes through the filtration medium, the water absorption granules are expanded by absorbing the water to block an oil passage, thereby reducing the flow capacity and preventing the water from passing through the filtration medium. A packed bed filter and filter equipment produced by the filtration medium designed by adopting the technical proposal have simple structure, the shape and the size of the original packed bed filter and the filter equipment are not changed, the good water absorption and blocking function is provided when solid impurities are filtered, and the accident caused by overmuch water mixed in fuel oil and engine oil is effectively avoided.
Description
Affiliated technical field
The utility model relates to a kind of filter medium with absorbent function.
Background technology
At present, fuel engines, compressor, engineering machinery etc. must be filtered oils before using oils, and it mainly is the solid particle that contains in the filtering oil.Yet in oils accumulating, use, oil storage tank, fuel tank etc. can flow in the oil because condensation produces water.Moisture meeting etching mechanism member in the oil, accelerated wear test increases oil consumption.Existing filter medium can only filter solid impurity, and can not filtering has the moisture of strong harm equally.
Summary of the invention
For the moisture impurity in the filtering fluid, the utility model provides a kind of filter medium with absorbent function, can be in the filtering solid impurity, and the filtering moisture impurity.
The technical scheme that its technical problem that solves the utility model adopts is:
Filter medium with absorbent function is laminated with by multilayered fibrous material to be formed, and is distributed with water-absorption particle in the fibrous material.When the moisture in the oil passes filter medium, absorbed by fibrous material and water-absorption particle immediately, thus the water content in the reduction oil.Moisture in oil more for a long time, water-absorption particle can absorb large quantity of moisture, and is expanded to several times even tens times of original volume, stops up oil circuit, reduces the flow velocity of fluid greatly, plays the warning effect.
Being laminated with in the structure of multilayered fibrous material, for guaranteeing the filtering accuracy of solid particle, reach better filter effect, the fibrous material that is in the exit position uses filter paper; Be to guarantee flow velocity, and better fixing water-absorption particle, that the fibrous material that is in the entry position is selected for use is fluffy, being laminated with of chemical industry synthetic fibers, glass fibre or the multiple fiber of porous.
Water-absorption particle is a hydroscopic high-molecular resin, and it has superpower water absorbing capacity, can absorb the hundred times of own wt even thousands of times moisture, and has very strong water holding capacity, and percentage of water loss is still very little under pressure.The water-absorbing resin of selecting for use can be the mixture of carboxymethyl cellulose, starch minor matters polyacrylonitrile, polyacrylamide, polyacrylic water-absorbing resin, polyacrylate water-absorbing resin or above water-absorbing resin.
The beneficial effects of the utility model are, the cleaner, the filter plant that utilize filter medium with absorbent function to produce under the situation that does not change original cleaner, the original geomery of filter plant, are removed moisture impurity when filtering solid impurity.This utility model can be used for filtering water-fast oils such as diesel oil, gasoline, machine oil, also can be used for filtering the fuel combination that is mixed with small amount of ethanol, methyl alcohol.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is the utility model structural section figure.
Fig. 2 is the utility model production process schematic diagram.
Among the figure: 11. filter paper, 12. hydroscopic high-molecular resin particles, 13. fluffy fibrous materials, 21. fiber stock supports, 22. conveyer belts, 23. blanking devices, 24. spray nozzles, 25. binding agents, 26. filter paper stock supports, 27. milling rollers, 28. drying boxes.
The specific embodiment
Figure 1 shows that the filter medium sectional view with absorbent function, it is made up of filter paper (11), hydroscopic high-molecular resin particle (12), fluffy fibrous material (13).Fluffy fibrous material (13) is generally selected the material that is laminated with of glass fibre, chemical industry synthetic fibers or multiple fiber for use.Hydroscopic high-molecular resin particle (12) distributes equably and is fixed in the fluffy fibrous material (13).Filter paper (11) closely is laminated with fluffy fibrous material (13).
Figure 2 shows that filter medium production process schematic diagram with absorbent function.The fluffy fibrous material (13) of rolling is placed on the fiber stock support (21), conveyer belt (22) moves from left to right, carry fluffy fibrous material (13) through blanking device (23) below, blanking device (23) is sprinkling upon hydroscopic high-molecular resin particle (12) on the fluffy fibrous material (13) equably.For guaranteeing to be laminated with intensity, spray nozzle (24) can be gone up to fluffy fibrous material (13) and spray a spot of binding agent (25).The filter paper of rolling (11) is placed on the filter paper stock support (26), and milling roller (27) firmly rolls filter paper (11) and fluffy fibrous material (13) and is laminated with.Material after being laminated with forms the filter medium with absorbent function through drying box (28) oven dry processing.
Claims (6)
1. the filter medium with absorbent function is made up of fibrous material and water-absorption particle, and it is characterized in that: fibrous material has sandwich construction, closely is laminated with between multilayered fibrous material, is distributed with water-absorption particle in the fibrous material.
2. filter medium according to claim 1 is characterized in that described fibrous material is a filter paper.
3. filter medium according to claim 1 is characterized in that described fibrous material is the chemical industry synthetic fibers.
4. filter medium according to claim 1 is characterized in that described fibrous material is a glass fibre.
5. filter medium according to claim 1 is characterized in that described water-absorption particle is a hydroscopic high-molecular resin.
6. filter medium according to claim 1 is characterized in that described water-absorption particle evenly distributes and is fixed in the fibrous material.
