Problems solved by technology

Aerators are usually processed with many micropores or directly made of porous materials. For example, in the past, manufacturers of aerators mostly used rubber, plastic or fiber to process aerators with many micropores or flexible materials such as sponges. Although this type of aerator has a good aeration effect, it is troublesome to process, not resistant to corrosion and acid and alkali, easy to age, and has a short service life. At present, some manufacturers use corundum microporous material aeration sheets to make Aerator, although this kind of corundum microporous aeration sheet is resistant to corrosion, acid and alkali, not easy to age, and has a long service life, its corundum aeration sheet has small porosity, large fan resistance, poor aeration effect, and poor sewage purification quality.

Embodiment 1

[0014] Embodiment 1, in Fig. 1, it is made up of aeration plate 1, outer jacket 2, inner sleeve 3, one-way ventilation valve 4, vent pipe 5, splint 7, and described outer jacket 2, inner sleeve 3, splint 7 are durable It is made of acid-base and corroded plastic. The lower end of the inner sleeve 3 is provided with an air inlet joint 8 in the middle, and its upper end is connected with the outer sleeve 2 with threads. The air inlet joint 8 on the top passes through the upper wall of the ventilation pipe 5 and is connected with the one-way ventilation valve 4. The aeration sheet 1 is planar, and the aeration sheet 1 is fixed between the outer casing 2 and the inner casing 3. The inside of the aerator 1 has honeycomb holes with a network structure, and the aerator 1 on the aerator is made of quartz sand, feldspar and resin as raw materials, and is manufactured according to the following method:

[0015] 1. First mix the two raw materials of 80% by weight, quartz sand with a part...

Embodiment 2

[0019] Example 2, the structure of the aerator is the same as that of Example 1, the difference is that: the aerator plate 1 is made of quartz sand, dolomite and glass water as raw materials, and is manufactured according to the following method:

[0020] 1. First mix the two raw materials of 95% by weight, quartz sand with a particle size of 30-70 mesh and 5% by weight of dolomite in a mixer,

[0021] 2. Add 6% of the total weight of glass water to the above mixture, and evenly mix and roll to form a mixture.

[0022] 3. Add the mixture into the mold and press it into a product blank.

[0023] 4. Send the billet into a high-temperature calcination furnace and calcine it at a temperature of 900-1300°C. After testing, the porosity of the aeration sheet is 30.6%.

Embodiment 3

[0024] Embodiment 3, the structure of the aerator is the same as that of Embodiment 1, the difference is that the aerator 1 is made of quartz sand, talc and resin as raw materials, and is manufactured according to the following method:

[0025] 1. First mix the two raw materials of quartz sand with a weight percentage of 55% and a particle size of 70-150 mesh and talc with a weight percentage of 45% in a mixer,

[0026] 2. Then add 3% resin of its total weight to the above mixture, and evenly mix and roll to form a mixture.

[0027] 3. Add the mixture into the mold and press it into a product blank.

[0028] 4. Send the billet into a high-temperature calcination furnace and calcine it at a temperature of 900-1300°C. After testing, the porosity of the aeration sheet is 33.5%.

Abstract

This invention discloses a microporous quartz aerator, which comprises: an aeration plate, an outer jacket, an inner jacket, and an aeration pipe. The lower end of the inner jacket is fixed with an aeration joint, and its upper end is connected with the outer jacket. The aeration joint is connected with a unidirectional air valve. The planar or spherical aeration plate is fixed between the two jackets, and has honeycomb-like pore network inside. The aeration plate is produced by: mixing quartz sand 55-95%, high-temperature fluxing agent 5-45%, and adhesive (3-6 wt. % of quartz sand and fluxing agent), and calcining at high temperatures. The aeration plate has a porosity 30% higher than that of microporous corundum aeration plate, thus has such advantages as low wind resistance, large interface of gas and liquid, uniform bubble diffusion, adequate oxygen dissolution, no air hole blockage, good aeration effect, high wastewater purification quality, increased wastewater treatment efficiency by more than 5 times, good corrosion, acid and base resistance, no aging, and long service life.

Description

technical field [0001] The invention relates to an oxygenation aeration diffusion device, in particular to a quartz microporous aerator for sewage oxygenation treatment. Background technique [0002] The sewage treatment tanks are equipped with aerators for absorbing and filtering impurities in the sewage to purify the sewage. The aerators are equipped with microporous aeration sheets, and the air passes through the aeration sheets to generate a lot of water in the sewage. Small air bubbles, the air bubbles absorb small impurities in the sewage, and the impurities continue to float on the surface of the sewage with the air bubbles. After filtering, the impurities are removed to achieve the purpose of purifying the sewage, so that the sewage can be reused after treatment and reduce water consumption. Aerators are usually processed with many micropores or directly made of porous materials. For example, in the past, manufacturers of aerators mostly used r...
