Abstract
The utility model discloses a high-strength glass fiber reinforced plastic biogas digester. The high-strength glass fiber reinforced plastic biogas digester comprises a semi-ellipsoidal upper cover and a lower pit, wherein the upper cover and the lower pit both are provided with flange sides, the edge of the flange side is provided with a circle of high-strength fiber belt, and the upper cover is connected with the lower pit through the flange side. In comparison with the conventional glass fiber reinforced plastic biogas digester, the biogas digester provided by the utility model is provided with the high-strength fiber belt at the edge of the flange side thereof, and the upper cover and the lower pit base SMC (sheet molding compounding) sheets are integrally formed by mould pressing, thus, after the upper cover and the lower pit of the glass fiber reinforced plastic biogas digester are formed by mould pressing, the integrated intensity of the upper cover and the lower pit flange side of the biogas digester is improved greatly, and the flange sides are prevented from generating microcracks for the reasons of collision and so on in the loading and unloading process of a forklift, the transportation process and the installation process. The high-strength fiber belt can prevent the cracks from stretching and expanding, the high-strength fiber belt also can be added to other parts of the glass fiber reinforced plastic biogas digester, and the upper cover and the lower pit thereof according to requirement so as to meet the requirement on the strength of the glass fiber reinforced plastic biogas digester, and a firm foundation is provided for the expansion use of the glass fiber reinforced plastic biogas digester, and the upper cover and the lower pit thereof.
Description
Technical field
The utility model relates to a kind of methane-generating pit, relates in particular to a kind of high strength glass fiber reinforced plastic methane-generating pit.
Background technology
At present biogas engineering be widely used in that excrement is dirtyly administered, the polynary fields such as work water waste water and domestic sewage treatment and stalk, the processing of domestic waste biogas.Biogas technology provides guarantee for rural area new forms of energy construction development, and has realized biogas processing and the comprehensive utilization of resources of domestic waste, has improved greatly rural area, the production in city, living environment.Methane-generating pit generally is divided into cement methane-generating pit and biomass pool built from glass fiber reinforced plastic.The cement methane-generating pit exists heavy, and construction period length, aerogenesis speed are slowly, not corrosion-resistant, intensity is low, work-ing life is short, the high deficiency of condemnation factor.The advantages such as biomass pool built from glass fiber reinforced plastic has easy construction, the construction period is short, aerogenesis speed is fast, corrosion-resistant, long service life.But the SMC sheet material mold pressing that the chopped strand that biomass pool built from glass fiber reinforced plastic is employing 〉=5mm-50mm strengthens forms, in the process of mold pressing, the SMC sheet material is when die cavity is suppressed, due to the damage of pressure to chopped strand, the physical length that makes fiber causes the intensity of product to reduce less than 〉=5mm-50mm.The upper cover of existing biomass pool built from glass fiber reinforced plastic and lower storage reservoir, flange often occurs in fork truck loading and unloading, carrying and installation process and produce tiny crack because of collision, because the summer in envrionment temperature winter changes and the methane-generating pit internal pressure changes repeatedly, cause upper cover, lower storage reservoir flange crackle constantly to extend and expansion, form to connect produce at last gas leakage, leak natural pond liquid, form secondary pollution and normal air feed.
The utility model content
For the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of high strength glass fiber reinforced plastic methane-generating pit that has solved above problem.
The technical solution of the utility model is: a kind of high strength glass fiber reinforced plastic methane-generating pit, the upper cover and the lower storage reservoir that comprise semielliptical shape, described upper cover and lower storage reservoir are equipped with flange, and described flange periphery is provided with a circle high strength fibre band, and described upper cover is connected with lower storage reservoir by flange.
As preferably, described high strength fibre bandwidth is 9cm-12cm.
The beneficial effects of the utility model are: the utility model uses the high strength fibre band at its flange periphery, and with upper cover, lower storage reservoir matrix SMC sheet material integral die forming, make biomass pool built from glass fiber reinforced plastic upper cover, lower storage reservoir greatly improve the bulk strength of upper cover of biogas digester and lower storage reservoir flange after compression molding, avoid fork truck loading and unloading, carrying and installation process flange to occur and produce tiny crack because of reasons such as collisions.The high-intensity fiber band has overcome extension and the expansion of crackle, this kind high strength fibre band also can as required, be added on other positions of biomass pool built from glass fiber reinforced plastic and upper cover, lower storage reservoir, satisfying its requirement of strength, for the expansion usability of biomass pool built from glass fiber reinforced plastic and upper cover thereof, lower storage reservoir provides solid basis.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1. upper cover; 2. high strength fibre band.
Embodiment
Embodiment: as a kind of embodiment of the present utility model, as shown in Figure 1, a kind of high strength glass fiber reinforced plastic methane-generating pit, the upper cover 1 and the lower storage reservoir that comprise semielliptical shape, described upper cover 1 is equipped with flange with lower storage reservoir, described flange periphery is provided with a circle high strength fibre band 2, and described upper cover 1 is connected with lower storage reservoir by flange, and described high strength fibre band 2 width are 9cm-12cm.
The production process of high strength fibre band 2: the high strength glass fiber of use 4800Tex or the long yarn of Black Warrior fiber after the unsaturated polyester resin preimpregnation, are the silk mouth of 9cm through a cover bore, form the wide continuous fiber band of 9cm.With receiving the yarn device, its collection package is become work in-process again.First overlay the high strength fibre band 2 that length equates with the flange girth on the flange mould of upper cover 1, lower storage reservoir during stem pressing glass reinforced plastics biomass pool, repave the SMC sheet material, then together once molding formed, the forming method of lower storage reservoir is also identical.
The utility model uses high strength fibre band 2 at its flange periphery, and with upper cover 1, lower storage reservoir matrix SMC sheet material integral die forming, make biomass pool built from glass fiber reinforced plastic upper cover 1, lower storage reservoir greatly improve the bulk strength of upper cover of biogas digester 1 and lower storage reservoir flange after compression molding, avoid fork truck loading and unloading, carrying and installation process flange to occur and produce tiny crack because of reasons such as collisions.The high-intensity fiber band has overcome extension and the expansion of crackle, this kind high strength fibre band 2, also can be as required, be added on other positions of biomass pool built from glass fiber reinforced plastic and upper cover 1, lower storage reservoir, satisfying its requirement of strength, for the expansion usability of biomass pool built from glass fiber reinforced plastic and upper cover 1 thereof, lower storage reservoir provides solid basis.
Claims (2)
1. high strength glass fiber reinforced plastic methane-generating pit, the upper cover (1) and the lower storage reservoir that comprise semielliptical shape, it is characterized in that: described upper cover (1) is all gone up equal flange with lower storage reservoir, described flange periphery is provided with a circle high strength fibre band (2), and described upper cover (1) is connected with lower storage reservoir by flange.
