Abstract
The invention belongs to the technical fields of filter cloth and filter cloth manufacturing methods and discloses an easily-cleaned filter cloth, a monofilament used for production and a method for manufacturing the filter cloth. The easily-cleaned filter cloth is characterized by comprising a filter cloth body with filter holes, wherein the side wall, adjacent to filter residues, of the filter cloth body is a smooth surface; the filter holes are of a platform shape; the diameter of the side, adjacent to the filter residues, of the each filter hole is smaller than that of the side, adjacent to a filtrate, of the each filter hole; and the area of one side, adjacent to the filtrate, of each filter hole is 1.3-3 times that of the side, adjacent to the filter residues, of each filter hole. In a filtering process, the diameter of the side, adjacent to the filter residues, of the each filter hole is smaller, so that the grains which cannot be filtered are stopped outside the filter cloth body, and the filtrate and small grains which enter into the filter holes can flow out smoothly from the filter holes. The small grains are not remained in the filter holes, so that the filter holes are prevented from being blocked. The surface of one side, located at the filter residues, of the filter cloth body is a smooth surface, so that the filter residues attached to the surface can be conveniently cleared away, the service life of the filter cloth is prolonged and the production cost is lowered.
Description
Technical field
The method and technology field that the invention belongs to filter cloth, produces the monofilament of this filter cloth and produce filter cloth relates to a kind of easy cleaning filter cloth concretely, produces with the monofilament and the method for producing this filter cloth.
Background technology
In industries such as medicine manufacturings, industrial filter cloth is widely used, and because of filtering accuracy requires height, the filter opening of filter cloth is smaller, in filter process, the filter opening of filter cloth is easy to be stopped up by fine particle, influences filter effect, because filter cloth is rough, granule enters into filter opening inside in addition, clean very difficulty, use a period of time just must change, increased production cost.In order to prevent to stop up, often adopt two-layer filter cloth, ground floor is the aperture filter cloth, the second layer adopts the macropore filter cloth, like this, has increased production cost equally.
Summary of the invention
The industrial filter cloth of easy cleaning that first technical problem that the present invention solves just provides a kind of difficult obstruction, is convenient to clean.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is:
Comprise the filter cloth body that has filter opening, described filter cloth body is a burnishing surface near filter residue one side, described filter opening is the platform shape of the aperture of close filter residue one side less than the aperture of close filtrate one side, and the area of close filtrate one side of described filter opening is 1.3-3 times near the area of filter residue one side.
Its additional technical feature is:
The area of close filtrate one side of described filter opening is 2.1-2.2 times near the area of filter residue one side.
Second technical problem that the present invention solves just provides a kind of monofilament of producing the industrial filter cloth of above-mentioned easy cleaning.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is:
This monofilament includes following materials in weight portion:
The polypropylene fibre double centner;
Terylene 3.9-4.1 kilogram;
Size 1.9-2.1 kilogram;
Rare earth alloy 0.29-0.3 kilogram;
With above-mentioned material through premix, extrude, traction, negative pressure dewater, dry.
Its additional technical feature is:
Described terylene is the 3.95-4.0 kilogram; Described size is the 1.95-2.0 kilogram.
The 3rd technical problem that the present invention solves just provides a kind of method of producing the industrial filter cloth of above-mentioned easy cleaning.
For solving the problems of the technologies described above, the technical scheme that the present invention proposes is:
This method comprises the following steps:
The first step is woven into initial filter cloth body with monofilament;
Second step, the pressure roller of initial filter cloth body that braiding is good by being arranged in parallel up and down, pressure between two pressure rollers is 48-55 tons, a pressure roller is the hot pressing roller, the temperature of this hot pressing roller is controlled at 187 ℃-192 ℃, another pressure roller is the normal temperature pressure roller, and the gait of march of initial filter cloth body is controlled at 3-30 meters/minutes;
The 3rd step, check, packing, warehouse-in.
Its additional technical feature is:
Pressure between two pressure rollers is 49-50 tons, and the temperature of described hot pressing roller is controlled at 189 ℃-190 ℃, and the gait of march of initial filter cloth body is controlled at 17-18 meters/minutes.
The industrial filter cloth of easy cleaning provided by the invention, compare with prior art and to have the following advantages: one, owing to comprise the filter cloth body that has filter opening, described filter cloth body is a burnishing surface near filter residue one side, described filter opening is the platform shape of the aperture of close filter residue one side less than the aperture of close filtrate one side, the area of close filtrate one side of described filter opening is 1.3-3 times near the area of filter residue one side, when filtering, the mixed liquor that contains filter residue filters through the industrial filter cloth of this easy cleaning, filtrate leaches through filter opening, filter residue is filtered out by filter cloth, because under the aperture of the filter opening of close filter residue one side, the particle that can not filter is trapped in the outside of filter cloth body, the filtrate and the granule that enter in the filter opening can flow out through filter opening smoothly, granule can not remain in the filter opening, therefore can not stop up filter opening, and the surface that is positioned at filter residue one side is burnishing surface, cleans for being convenient to attached to the filter residue on surface, prolong the service life of filter cloth, reduced production cost; Its two because described filter opening be near the area of filter residue one side 2.1-2.2 times near the area of filtrate one side, be more conducive to filter and cleaning; Its three, the industrial filter cloth production of this easy cleaning monofilament is produced owing to adopt polypropylene fibre and terylene to mix, in the time will crossing initial filter cloth body and extrude by pressure roller, filter opening is Paint Gloss, is convenient to filter, and is not easy to stop up; They are four years old, owing to will weave the pressure roller of initial filter cloth body well by being arranged in parallel up and down, pressure between two pressure rollers is 48-55 tons, a pressure roller is the hot pressing roller, and the temperature of this hot pressing roller is controlled at 187 ℃-192 ℃, and another pressure roller is the normal temperature pressure roller, the gait of march of initial filter cloth body is controlled at 3-30 meters/minutes, like this, can guarantee one side for smooth flat, and can be controlled at filter opening and be 1.3-3 times near the area of filter residue one side near the area of filtrate one side.
