Description
Technical Field
The utility model relates to an organic refuse treatment field specifically is an anaerobic fermentation jar arranges sand setting equipment.
Background
In recent years, with the increasing scientific and technological level and the continuous acceleration of urbanization process in China, the physical living and consumption level of people is steadily improved, and the phenomenon that the organic garbage generation amount in the places of catering industry, food processing industry, even resident families and the like is rapidly increased occurs. The untreated or improper treatment of the organic garbage can seriously affect the water environment and urban environment, and seriously harm the food safety and the human health; nowadays, people's awareness of environmental protection is gradually strengthened, and the effective treatment mode of the organic garbage is also closely concerned by people in all circles.
The organic garbage refers to the waste containing organic components in the domestic garbage. Mainly comprises food waste (mainly 'hogwash' produced by food and drink units, dining halls and the like), kitchen waste (mainly leftover vegetables and food residues in vegetable markets, supermarkets and the like), garden waste and organic parts collected after waste classification. These wastes are extremely easy to rot, have low calorific value and rich organic matter content, and are difficult to be properly treated by adopting a conventional incineration or landfill mode.
At present, in the field of organic garbage treatment, the anaerobic fermentation technology can effectively realize the treatment effects of harmlessness, reduction and reclamation. However, most of the existing anaerobic technologies in the market have no function of automatically removing the deposited impurities (namely settled sand) in the tank. The existing part of companies adopt anaerobic fermentation tanks with conical bottoms, the conical bottoms are provided with holes, settled sand naturally precipitates due to large specific gravity and is sucked out by a pump, but the settled sand on the conical surfaces is easy to generate a bridging phenomenon, so that the settled sand is prevented from being further discharged through a sand discharge port, and the sand discharge effect cannot be achieved; some companies open a plurality of sand discharge ports at the bottom of the anaerobic fermentation tank for sand discharge, but settled sand which is not opened is still accumulated and cannot be discharged. Some companies directly place a sand suction and collection pipe at the bottom of the fermentation tank, but because the position of a pipeline opening is fixed, only the settled sand at the pipeline opening part can be sucked, and the settled sand at other parts of the tank bottom cannot be solved; and in some companies, materials are desanded and then are sent into a fermentation tank, but no equipment can achieve hundreds of treatment effects, the materials still have sand which enters the digestion tank, and settled sand is accumulated at the bottom of the tank within one or two years due to huge daily treatment capacity of the digestion tank.
This is because anaerobic fermentation tank is a confined environment, and the sand setting in the jar body is piled up and can't carry out the range inspection and is patrolled and examined, often piles up several meters when discovering the sand setting and heavily influences the effective volume of fermentation tank to probably cause the damage to jar interior equipment. In addition, the running of the fermentation tank is supported by a large number of microorganisms in the tank body, and the microorganisms need to stabilize a proper reaction environment, so that the tank cleaning and sand removal are not suitable, and huge economic loss can be brought to the whole kitchen waste treatment plant by stopping the tank cleaning.
Therefore, there is a need for a new device for discharging settled sand in an anaerobic fermentation tank for organic garbage to solve the above problems.
