Problems solved by technology

The existing filter tubes are only flat, and the folded ends of the filter tubes are divided into pointed and square. The existing plastic filter tubes have dead angles for pulse cleaning, resulting in poor cleaning effect and small filter area; the dust collector has a high operating pressure difference; Replace traditional filter bags

Embodiment 1

[0030] Stir 3-aminopropylmethyldimethoxysilane, polyoxyethylene castor oil and fatty acid ester at 90°C for 1 hour, then add polyhydroxybutyrate, stir at 100°C for 20 minutes, then add ethylene-acetic acid Vinyl ester copolymer and polydioxanone, stirred at 140°C for 2 hours, cooled to room temperature to obtain a mixture; the mixture, polytetrafluoroethylene particles, methyltrimethoxysilane, dialkyldithio Pyridine phosphate, sodium lauryl sulfate, and hydroxyl-terminated polybutadiene were mixed with a mixer to form a uniformly dispersed mixture; then the mixture was heat-treated at 170°C and 4MPa for 4 hours; then at 235°C, the The heat-treated mixture is granulated by an extruder to obtain a plastic composition, that is, a plastic composition for a plastic filter pipe;

[0031] The plastic composition is mixed with polyurea formaldehyde and paraffin to obtain a raw material composition for plastic filter pipes, which is added to an injection molding machine, and the crude ...

Embodiment 2

[0034] Using the preparation method of Example 1, the reinforcing ring is located in the pipe body, and is connected to the pipe body through a reinforcing rod; the cross section of the pipe body is a gear-shaped structure; the tooth top and tooth groove of the gear-shaped structure are arc-shaped structures; The ring is located at one end of the tube body; there are 8 reinforcing rods; the contact points between the reinforcing rods and the reinforcing rings are evenly distributed on the reinforcing ring; the reinforcing rods are of flat structure (thickness is 3% of the length); The tooth groove of the gear-shaped structure; the length of each reinforcing rod is the same; the angle of the arc structure is 150°C; the height of the teeth of the gear-shaped structure is 30% of the length of the reinforcing rod; the above structures are conventional geometric structures.

[0035] After several actual measurements, the dust removal rate of the plastic filter tube of this embodimen...

Embodiment 3

[0038] Using the preparation method of Example 1, the reinforcing ring is located in the pipe body, and is connected to the pipe body through a reinforcing rod; the cross section of the pipe body is a gear-shaped structure; the tooth top and tooth groove of the gear-shaped structure are arc-shaped structures; The ring is located at one end of the pipe body; there are 4 reinforcing rods; the contact points between the reinforcing rod and the reinforcing ring are evenly distributed on the reinforcing ring; the reinforcing rod is a flat structure (thickness is 3% of the length); The tooth groove of the gear-shaped structure; the length of each reinforcing rod is the same; the angle of the arc structure is 40°C; the height of the teeth of the gear-shaped structure is 33% of the length of the reinforcing rod.

[0039] After many actual measurements, the dust removal rate of the plastic filter tube in this embodiment reaches 99%. Under the same size, the filtration efficiency is 2.5 ...

Abstract

The invention discloses a plastic filter tube and a composition applied to the same. The composition is prepared from 3-aminopropyl methyl dimethoxysilane, polyoxyethylene caster oil, aliphatic ester, polyhydroxybutyrate, a vinyl-vinyl acetate copolymer, poly(p-dioxanone), teflon particles, methyltrimethoxysilane, bialkyl dithiophosphate pyridine, lauryl sodium sulfate and hydroxylterminated polybutadiene; a raw material composition for the plastic tube is obtained after mixing of the composition with polyurea formaldehyde and paraffin and is added in an injection molding machine to prepare the filter tube. The plastic filter tube can be washed again and reused and is the environment friendly product, traditional filter bag equipment can be replaced directly, modification of existing dust collecting equipment is not needed, the equipment is long in service life, and the service life can be 10 times more than that of the traditional equipment.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to a plastic filter pipe and a composition used for the plastic filter pipe. Background technique [0002] With the development of modern industry, the impact of dust on the environment and human health is becoming more and more serious. Dust pollution is effectively controlled. In recent years, the country has paid more and more attention to environmental protection and the phenomenon of global warming has become serious. In order to advocate energy saving and carbon reduction, the environmental protection industry is booming. It has become the consensus of all to develop and purify the living environment of human beings. The existing filter tubes are only flat, and the folded ends of the filter tubes are divided into pointed and square. The existing plastic filter tubes have dead angles for pulse cleaning, resulting in poor cleaning effect and small fi...
