Problems solved by technology

However, due to the improvement of urban sewage treatment and discharge standards, the efficiency of nitrogen and phosphorus removal cannot be further improved due to the bottleneck of the traditional activated sludge process, and the traditional activated sludge process cannot meet the discharge standards; at the same time, under the condition of insufficient land resource reserves , there is an urgent need for efficient and stable treatment technology, not only to meet the objective conditions of small footprint, but also to ensure the stability of the effluent and even advanced treatment and reuse
Therefore, the development of a landscape ecological decentralized sewage treatment device has become the goal of sewage treatment technicians, but the traditional landscape ecological decentralized sewage treatment device has a large footprint, low sewage treatment efficiency, and poor sewage treatment quality. shortcoming

Embodiment 1

[0030] like figure 1 As shown, the biological feces recovery device of the present invention includes a crushing mechanism 1, a centrifugal mechanism 2, a drying mechanism 3, a compacting mechanism 4, a forming mechanism 5, and a collecting mechanism 6; the centrifugal mechanism 2 is used for centrifugal dehydration and will be dehydrated The material is transferred to the centrifugal mechanism 2; the compacting mechanism 4 includes two matching squeeze rollers, which compress the dried material into a strip shape and transfer the strip-shaped material to the forming mechanism 5, and the forming mechanism It includes two opposite forming rollers, the surface of the forming rollers has a mold cavity 51, and the two forming rollers cooperate with each other to extrude the material into shape. The structure dries and solidifies the feces, thereby ensuring the recovery of biological feces, reducing the pollution of rivers and water by biological feces, improving the recycling and ...

Embodiment 2

[0038] The biological excrement recovery device in embodiment 1, its recovery method is:

[0039] Step 1: Put fresh biological feces, straw, and water into the crushing mechanism 1 to crush and stir for 12-15 minutes to obtain a mixture, the water content in the mixture is 78-80%, and the average particle size is 6-8mm;

[0040] Step 2: Put the mixed material into the centrifugal mechanism 2, and make the mixed material undergo centrifugation and dehydration for 4-6 minutes, so that the water content in the mixed material will be 40-45%;

[0041] Step 3: Put the dehydrated mixture into the drying mechanism 3 and spread it evenly to a thickness of 1-1.3cm; use an open flame at 550-600°C to dry the lower part of the mixture for 20-30s to make the content of the mixture The water volume will be 20-24%;

[0042] Step 4: put the mixture into the compacting mechanism 4, and extrude the mixture into a strip with a thickness of 1-1.5cm under a pressure of 300-350kPa;

[0043] Step 5...

Embodiment 3

[0048] In the biological feces recovery device in embodiment 1, the ceramic sheet adopted by the conveyor belt comprises a reinforcement layer, a braided layer, and a ceramic layer from the inside and outside, and the reinforcement layer is made up of the following materials by weight: 12 parts of iron, 0.3 parts of carbon, 0.4 parts of aluminum, 1 part of silicon, and 0.3 parts of nickel; the braiding layer is made of the following materials by weight: 3 parts of iron wire, 1 part of aluminum wire, 1.5 parts of glass fiber, and 2 parts of ceramic fiber; the ceramic layer is made of the following materials Composition: 16 parts of vermiculite, 20 parts of sepiolite, 3 parts of iron slag, 9 parts of perlite, 6 parts of calcium oxide, 8 parts of alumina, 40 parts of ceramic powder, 16 parts of glass powder, 2 parts of bentonite, 7 parts Nickel-chromium alloy, 10 parts lithium oxide, 13 parts expanded perlite, 15 parts mullite. The reinforcing layer of this composition has the ch...

Abstract

The invention relates to the field of manure recovery or treatment, in particular to a biological manure recovery device which comprises a crushing mechanism, a centrifugal mechanism, a drying mechanism, a pressing mechanism, a forming mechanism and a collecting mechanism. The centrifugal mechanism is used for centrifugal dewatering, dewatered materials are transferred to the centrifugal mechanism, the pressing mechanism comprises two matched extrusion rollers, the extrusion rollers are used for pressing the dried materials into strips and transferring the strip materials to the forming mechanism, the forming mechanism comprises two opposite forming rollers, the surface of each forming roller is provided with a die cavity, and the two forming rollers are mutually matched to extrude the materials. Manure is dried and solidified, so that the biological manure is recovered, pollution of the biological manure to rivers and water can be reduced, and manure recovery degradation speed is increased. The structure is convenient and simple, bio-fuels or feed can be rapidly manufactured, production can be facilitated, miniaturized manufacture can be realized, the biological manure recovery device is applicable to mini-plants or livestock farms, and cleanness and sanitation of workplaces can be ensured.

Description

technical field [0001] The invention relates to the field of excrement recovery or treatment, in particular to a biological excrement recovery device. Background technique [0002] my country's water pollution and water resource shortages are becoming more and more serious, and higher requirements are placed on the effect of sewage treatment. However, due to the improvement of urban sewage treatment and discharge standards, the efficiency of nitrogen and phosphorus removal cannot be further improved due to the bottleneck of the traditional activated sludge process, and the traditional activated sludge process cannot meet the discharge standards; at the same time, under the condition of insufficient land resource reserves , there is an urgent need for efficient and stable treatment technology, which not only meets the objective conditions of small footprint, but also needs to ensure the stable compliance of the effluent and even advanced treatment and reuse. Therefore, the d...
