Preparation method of rural toilet urn-shaped cement manure pit

Abstract

The invention relates to a preparation method of a rural toilet urn-shaped cement manure pit. The method can be used for effectively solving the problem of manure pit production for meeting the rural requirement. The method comprises the following steps of: mixing 22-27 weight percent of sulfate aluminate cement, 35-40 weight percent of sand and 35-40 weight percent of water together at the temperature of 0-35 DEG C to form a pasty cement mixture, uniformly coating the pasty cement mixture onto cloth of a urn-shaped die by using an arc cement tool, sticking a glass fiber mesh to the cement mixture surface, secondarily coating the pasty cement mixture onto the glass fiber mesh, pressing the glass fiber mesh to form a finished surface, and forming a urn body; and performing first water spray maintenance in 2 hours after the urn body is manufactured, stripping after 4 hours, performing second water spray maintenance after stripping, performing third water spray maintenance after 24 hours, performing final water spray maintenance after 48 hours, and airing to obtain a finished product. The method has the advantages of simple process, easiness for production, high production efficiency, high product strength, long service life, low cost, cleanliness, sanitation, energy conservation and no environmental pollution.

Description

1. Technical field [0001] The invention relates to a septic tank, in particular to a method for preparing a farm toilet urn-type cement septic tank. 2. Background technology [0002] Septic tanks are necessary equipment for storing feces in rural areas. At present, they are mostly made of artificial masonry or dug pits. This simple type of septic tank is very unhygienic to use. With the development of science and technology and the requirements for environmental protection, new types of septic tanks People are concerned about septic tanks. At present, there are cement prefabricated septic tanks, but due to problems in structure, materials and production methods, their use is not satisfactory. Production, due to the short service life, portland cement was used for prefabrication.

[0002] Septic tanks are necessary equipment for storing feces in rural areas. At present, they are mostly made of artificial masonry or dug pits. This simple type of septic tank is very unhygienic to use. With the development of science and technology and the requirements for environmental protection, new types of septic tanks People are concerned about septic tanks. At present, there are cement prefabricated septic tanks, but due to problems in structure, materials and production methods, their use is not satisfactory. Production, due to the short service life, portland cement was used for prefabrication. The prefabrication process of portland cement requires steel structure, and the amount of cement is large and heavy, which is inconvenient to transport, and the demoulding time is long and the setting period is long, which is not conducive to large-scale Production

Around 2007, plastic was used to produce urn-shaped septic tanks. First, the production cost of using new raw materials was high, and each set was about 350 yuan. For rural toilets, the price was too high and was not promoted; The cost of recycling plastics is about 300 yuan per set. Due to the insufficient pressure resistance and the increase of soil and sand moisture in the rainy season, it is easy to be damaged, and the cost reduction is not obvious. Rural farmers do not accept it.

The cement products combined with magnesium chloride and magnesium oxide are easy to return to chlorine and deform when exposed to water and humidity, and the technology is unstable, so they have not been widely used as materials for septic tanks.
