Abstract

The utility model relates to a combined sintering microporosity filter pipe, which can kill, filtrate, absorb and restrain the generate of nitrito. Tn the upper end of the pipe is a water outlet, thread is in the inner wall of the water outlet, and the lower end of the pipe is pipe bottom. Water enters pipe cavity through the pipe body from the outer wall, and goes out from the water outlet. The material of the pipe body is composed of low pressure macromolecule polyethylene with molecular weight of above 9 million, medical powder activity carbon, and ooze silver activity carbon, their weight percent in turn is 66_76: 30_40: 4_10. The materials are mixed and loaded to a mould, the mould is sintered in a celsius degree of 120_220 for 70_120 min together with the materials, so the pipe body is formed. The pipe bottom is adhered to the pipe body in heat block method by a polyethylene board.

Description

Combined sintering micropososity filter pipe

The utility model relates to a kind of filter in the water fountain.

Because water quality is constantly polluted, drinking water quality constantly descends.Be purifying drinking water, people adopt in bulk ooze silver-colored grain active carbon and places in the water fountain and filter.The silver-colored grain active carbon that oozes in bulk has three shortcomings: the one, and the water of going out earlier is black carbon water; The 2nd, under the percussion of water, carbon granules rubs mutually, and the carbon particulate of generation still enters in the drinking water; The 3rd, infiltrate the silver ion in the granulated carbon, to experience all sorts of and wash away, adhesive force weakens and enters in the water, and the silver ion of drinking water is exceeded standard.

The purpose of this utility model is to provide a kind of can overcome above-mentioned three shortcomings of silver-colored activated carbon of oozing in bulk, has filter aseptic, that filter, adsorb, suppress functions such as nitrate anion generation.

Structure of the present utility model is the columnar hollow pipe at a band end.The pipe upper end has delivery port (1), delivery port (1) inwall has screw thread (2) so that be connected with the lid of water fountain, and pipe shaft (3) has filtration, absorption, bactericidal action, and water is from pipe shaft (3) outer wall, enter the inner chamber (4) of pipe through pipe shaft, flow into outlet pipe from delivery port (1).Also having a pipe end (5), is to be made by the ultra high molecular polyethylene material, and the lower end of hot sticky method and pipe shaft (3) is bonding.

The percentage by weight that the material of described pipe shaft (3) is formed is: molecular weight is at the low pressure ultra high molecular polyethylene 900,000 or more: the medical powder activated carbon: oozing silver-colored activated carbon is 66-76:30-40:4-10, fully the mixing mould of packing into.Pipe places in the insulating box together with mould, at 120 ℃～220 ℃, through 70-120 minute sintering, the demoulding of cooling back pipe.The length of pipe shaft (3) intercepts on demand.

Describedly ooze producing of silver-colored activated carbon, add 0.5-1 kilogram powder activated carbons with 3000 milliliters of 0.1-1% silver nitrates and fully stir, filter with 120-180 purpose sieve then,, pulverize again in the 100C oven dry.

Description of drawings:

The micropore sintered combined filtration pipe of Fig. 1

The profilograph of the micropore sintered combined filtration pipe of Fig. 2

Embodiment 1:A produces and oozes silver-colored activated carbon, adds 1 kilogram of powder activated carbon with 3000 milliliter of 1% silver nitrate, and the stirring through 1 hour is filtered at 120 mesh sieves, 100 ℃ of oven dry, pulverizes.

B batching: take by weighing sub-polyethylene 1000 grams of low pressure superelevation, powder activated carbon 400 grams, ooze silver-colored activated carbon 100 grams, fully mix, in the mould of packing into.

The C sintering: the pipe tire places in the insulating box together with mould, and temperature is controlled at 150 ℃, and sintering time is 60 minutes.

D processing: pipe is intercepted 200 millimeters long, is that 10 millimeters polyethylene boards are done to manage at the ends with the sizable thickness of tube outer diameter, with hot sticky the end and pipe shaft bonding, and in 20 millimeters of the mouth of pipe inwall length machining internal thread, the screen pipe of household water drinking device.

Claims

1, micropore sintered combined filtration pipe, be applicable to the purification of water quality, be specially adapted to do the filter in the water fountain, pipe comprises delivery port (1), there is screw thread (2) at the inwall place of delivery port (1), pipe shaft (3), inner chamber (4), the pipe end (5), the material of pipe shaft (3) by molecular weight at the low pressure ultra high molecular polyethylene more than 900,000, the medical powder activated carbon, oozing silver-colored activated carbon forms, the pipe end is a polythene material, it is characterized in that the percentage by weight that the material of pipe shaft (3) is formed is: low pressure ultra high molecular polyethylene: medical powder activated carbon: oozing silver-colored activated carbon is: 66-76: 30-40: 4-10.
