Abstract

The utility model provides a high strength and thin shell methane tank, the tank wall can be a laminated construction that magnesium chloride, magnesium oxide, quartz powder, a frozen layer of glass fiber mixed slurry and a reinforced layer of glass fiber cloth can be alternately used, and the inner wall is coated with water proof coating. The methane tank has high strength, having light weight, and having favorable air tightness; compared with the cost of the utility model and the cost of existing concrete methane tank, the high strength and thin shell methane tank can be a complete commercial methane generator used for the countryside.

Description

High strength and thin shell methane tank

The utility model relates to a kind of fermentation unit, particularly a kind of biogas generating device.

The biogas generating device of China rural households use at present mostly is the methane-generating pit of deposit concrete structure, because there is the shortcoming of easy to leak in concrete structure, for guaranteeing the high-air-tightness of methane-generating pit, must there be a high quality construction crew that is skilled in technique to carry out site operation, otherwise be difficult to guarantee build guality.Another kind of constructional method is that concrete is made precoated plate, transports to field joint then and becomes methane-generating pit, and its shortcoming is that precoated plate weight is not easy to transportation greatly, and its joint easily leaks gas.The site operation of this noncommodityization of prior art has limited biogas applying in China rural area to a great extent.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, provide a kind of can complete commercial biogas generating device, this biogas jar is the intensity height not only, and is in light weight, and resistance to air loss is good, can life-time service.

The purpose of this utility model is achieved in that

This high-strength thin-walled biogas jar has charging and discharging mouth ［ 3 ］, methane outlet ［ 1 ］ and fermented liquid overflow port ［ 4 ］, tank wall is the stepped construction that magnesium chloride, magnesium oxide, silica powder, glass fibre mixed pulp solidification layer ［ 6 ］ and glasscloth enhancement Layer ［ 7 ］ are used alternatingly, and inwall scribbles water-proof coating ［ 8 ］.

The stepped construction of above-mentioned biogas tank wall is made of three layers of mixed pulp solidification layer that is used alternatingly and layer glass cloth at least, the concrete thickness of tank wall can be decided according to tank body volumetrical size, generally can be between 10-30mm, the water-proof coating of inner tank wall can be polyurethane water-proof paint or epoxy resin etc.

Above-mentioned biogas jar can be a top returning water type biogas jar, also can be cover-floating type biogas jar or hydraulic type biogas jar and other various ways.

The utility model contrast prior art has the following advantages and positively effect:

This biogas jar that the utility model provides is owing to adopted light-weight high-strength material, satisfy at tank intensity under the prerequisite of service requirements, wall thickness only is the 1/3-1/5 of concrete structure, weight only is 1/10 of co-content concrete structure, be suitable for the transportation of goods, leak rate is up to state standards after testing, 24 hours are no more than 3%, the biogas jar intensity height that the utility model provides, in light weight, resistance to air loss is good, and cost is close with the existing concrete methane-generating pit, for vast rural area provide a kind of can complete commercial biogas generating device, need not carry out any processing after the peasant buys back and can directly use, the popularization that will help biogas greatly with popularize.

Below in conjunction with specific embodiment and accompanying drawing the utility model is described in detail:

Fig. 1: be according to the top returning water type biogas jar vertical profile synoptic diagram that the utility model proposes;

Fig. 2: the partial enlarged drawing that is Figure 1A portion;

Fig. 3: be according to the cover-floating type biogas jar vertical profile synoptic diagram that the utility model proposes;

Fig. 4: be according to the hydraulic type biogas jar vertical profile synoptic diagram that the utility model proposes;

With reference to Fig. 1, this jar is a top returning water type biogas jar, and the top of tank body ［ 5 ］ is provided with charging and discharging mouth ［ 3 ］, and top cover ［ 2 ］ is provided with methane outlet ［ 1 ］, vertically is provided with fermented liquid upflow tube ［ 4 ］ in the tank body.

With reference to Fig. 2, the stepped construction that the tank wall of above-mentioned biogas jar is used alternatingly for mixed slurry solidification layer ［ 6 ］ and glasscloth enhancement Layer ［ 7 ］, inwall scribbles water-proof coating ［ 8 ］.

The proportioning weight of magnesium chloride, magnesium oxide, silica powder, glass fibre is 3:6:1:1 in the used mixed pulp, adds water move to the mud shape, and used glasscloth is the neutral and alkali glasscloth, makes the biogas jar through the tank body Mould Machining.

With reference to Fig. 3, this jar is prisoner's bell-type biogas jar, is divided into tank body ［ 5 ］ and floating cover ［ 2 ］ two portions, and the top of floating cover is provided with methane outlet ［ 1 ］, be respectively equipped with opening for feed ［ 3 ］ and fermented liquid overflow port ［ 4 ］ on the sidewall of tank body, can carry out floating to cover to take off during discharging.

With reference to Fig. 4, this jar is a hydraulic type biogas jar, the top of tank body ［ 5 ］ is provided with charging and discharging mouth ［ 3 ］, be stamped top cover ［ 2 ］, be respectively equipped with fermented liquid overflow port ［ 4 ］ and additional opening for feed ［ 9 ］ on the sidewall of tank body, additional opening for feed is used for intermittently replenishing human and animal excreta, and to prolong the aerogenesis time, methane outlet ［ 1 ］ is located at tank body top.

Fig. 2,3,4 tank wall structure are with shown in Figure 2.

The principle of work of above-mentioned biogas jar is, is fermentation raw material with crop stalk, human and animal excreta, adds entry and carries out anaerobically fermenting generation biogas (methane gas about 70%), and fermented liquid overflow port water receiving is pressed the pond, plays the effect of gaseous tension in the surge tank.
