Description

Technical Field

[0001] The utility model belongs to the field of amino acid marsh fertilizer fermentation equipment, and particularly relates to an amino acid marsh fertilizer fermentation device. Background Technique

[0002] Amino acid marsh fertilizer is mainly refined from marsh slag and marsh liquid. Marsh slag and marsh liquid are by-products generated through the biogas fermentation process. Biogas fermentation is a process in which organic wastes, such as crop straws, livestock and poultry manure, food processing wastes, etc., are converted into biogas through the action of microorganisms under anaerobic conditions. After fermentation is completed, the remaining solid substances are called marsh slag, and the liquid substances are called marsh liquid. Marsh slag and marsh liquid contain rich organic matter, nitrogen, phosphorus, potassium and other nutrient elements as well as various microbial metabolites. These substances can be further processed and refined to produce high-quality amino acid marsh fertilizer;

[0003] According to the Chinese patent application number: 201920946111.X, there is disclosed a fermentation device for the production of amino acid organic fertilizer, including a base, a water tank and a housing. The middle of the top of the base is fixedly connected to the bottom of the housing through a triangular bracket. One side of the top of the housing is fixedly provided with a first motor, and the output shaft of the first motor is fixedly connected to one end of a first stirring shaft. The outer wall of the first stirring shaft is fixedly provided with first stirring blades. The other side of the top of the housing is fixedly provided with a second motor, and the output shaft of the second motor is fixedly connected to one end of a second stirring shaft. The outer wall of the second stirring shaft is fixedly provided with second stirring blades. The water in the water tank is heated to a suitable fermentation temperature by a heater, and the temperature control switch keeps the water in the water tank at the same temperature all the time. The water pump transports the water in the water tank to make the water circulate in the water pipe wound around the outer wall of the fermentation barrel, so that the temperature of each part of the fermentation barrel is uniform, thereby making the raw materials ferment evenly;

[0004] The prior art effectively solves the problem that the amino acid organic fertilizer fermentation uses a heater to adjust the fermentation temperature, and cannot make the temperature of each part of the fermentation barrel uniform, resulting in uneven fermentation of the raw materials, thereby reducing the fermentation rate. It has the advantages of uniform heating temperature and increased fermentation rate. However, this amino acid marsh fertilizer fermentation device is not convenient to separate the marsh liquid and marsh slag after fermentation is completed, which is not conducive to subsequent fertilizer extraction.

When the spiral blade 304 rotates, it can drive the solid biogas residue in the inner cavity of the conveying pipe 301 to be discharged through the slag discharge pipe 308. The biogas slurry in the biogas residue falls into the inner cavity of the liquid collection tank 305 through the mesh 306 and is discharged through the drain pipe 307.

When the spiral blade 304 rotates, it can drive the solid biogas residue in the inner cavity of the delivery pipe 301 to be discharged through the slag discharge pipe 308. The biogas slurry in the biogas residue falls into the inner cavity of the liquid collection tank 305 through the mesh 306 and is discharged through the liquid discharge pipe 307. The centrifugal force generated by the high-speed rotation of the liquid discharge pump 401 drives the biogas slurry in the inner cavity of the biogas slurry chamber 104 to be transported to the next process through the liquid inlet pipe 402 and the liquid outlet pipe 403.
