Description

Technical Field

[0001] The invention relates to the technical field of organic liquid fertilizer production, and in particular to novel organic liquid fertilizer production equipment and a production process. Background Art

[0002] Organic liquid fertilizer is a liquid fertilizer based on organic matter, usually fermented from plant and animal residues or microorganisms. They are rich in nutrients, such as nitrogen, phosphorus, potassium, etc., which are very beneficial to plant growth. Organic liquid fertilizer production equipment is used to process agricultural waste, animal manure, plant residues and other raw materials into organic liquid fertilizer. The equipment processing process includes fermentation tanks, mixing equipment, filtration systems and automatic filling equipment, which can effectively improve the utilization rate of waste, convert agricultural waste into valuable organic fertilizer, and reduce the burden of waste on the environment.

[0003] For example, the publication number: CN102249743B discloses a method for producing organic concentrated composite liquid fertilizer from biogas slurry at room temperature, aiming to provide a method for producing organic concentrated composite liquid fertilizer from biogas slurry with low cost and high degree of automation. The method is that the biogas slurry is filtered out of large particles including plant fibers and sand particles through a biogas slurry filter tank and then enters a biogas slurry stock liquid storage tank, and is pumped to a biogas slurry mechanical filtration device, a biogas slurry multi-media filtration device and a biogas slurry precision filtration device to filter out macromolecular substances including algae, pesticide residues and bacteria, and then filtered through a biogas slurry cross-flow ultrafiltration device, and the non-permeated liquid enters a concentrated liquid storage tank, and the permeated liquid enters an aromatic polyamide membrane element concentration device for further concentration and separation, and the separated concentrated liquid enters the concentrated liquid storage tank and is then transported to a biogas slurry preparation tank for liquid fertilizer preparation, and the permeated liquid enters a water purification tank for equipment cleaning, and the liquid fertilizer is then sterilized by an online sterilization device and packaged for use as liquid fertilizer for crops, flowers and other plants;

[0004] However, the sterilization and disinfection methods used in traditional organic liquid fertilizer production equipment are relatively simple, and the killing effect on microorganisms is limited, which is difficult to meet the high requirements of modern agriculture for fertilizer safety. In the production of organic liquid fertilizer, the molecular structure of the fertilizer is large, and the efficiency of crop absorption is low, resulting in poor fertilizer efficiency. In addition, the traditional solution cannot effectively deal with large particle impurities and small particle fiber substances in the liquid. Due to the high viscosity of organic liquid fertilizer, the filter is easily clogged by impurities, resulting in the liquid being unable to pass smoothly, and the production efficiency is greatly reduced. Although some solutions use multi-stage filtration to improve the filtration effect, such as the above solution, it still requires frequent shutdown for filter element cleaning and replacement during cleaning, which affects the continuity of production. Therefore, a new type of organic liquid fertilizer production equipment and production process are urgently needed to solve such problems. Summary of the invention

[0024] Compared with the prior art, the advantages and positive effects of the present invention are:

[0025] 1. The present invention is equipped with a coarse filter and a fine filter to perform graded filtration on large particles and small particles respectively. The combined action of the multi-layer filter element and the vacuum pump makes the filtration process more efficient and significantly accelerates the liquid flow rate. Even in the face of relatively viscous biogas slurry, it can be quickly filtered without being easily blocked.

[0026] 2. The present invention integrates ozone disinfection and ultraviolet sterilization devices to form a double disinfection system. The ozone disinfector is combined with a gas-liquid mixing pump to allow the biogas slurry and ozone to fully contact and kill harmful microorganisms in the liquid. Subsequently, ultraviolet rays are used to further kill residual pathogens, and agricultural waste such as livestock and poultry manure and biogas slurry is processed into organic liquid fertilizer, reducing the pollution of the environment by waste and providing high-quality organic fertilizer for agricultural production.

[0027] 3. The present invention uses a vacuum pump to extract the gas inside the filter housing downward. During the gas extraction process, the liquid can be accelerated to flow downward through the filter element until it flows out from the bottom of the filter housing, which can greatly speed up the filtration speed.

[0028] 4. The present invention rotates the central axis at a speed determined according to demand, such as slowly rotating during filtering and quickly rotating when filtration is paused for special cleaning, to achieve a better cleaning effect through centrifugal action, and the cleaning leaves can be used to scrape and clean the upper surface of the filter element so that debris will not always cover the filter holes of the filter element, and the cleaning leaves are arranged in an arc shape, which cooperates with the continuous downward squeezing of particles above, and solid debris can be discharged outward during rotation until it is discharged from the outer edge of the filter element, thereby achieving a cleaning effect.

[0029] 5. The present invention connects the air duct and the water pipe to the external fan and the water source respectively. During the rotation of the cleaning blade, the air duct is connected to the air branch pipe, and the air branch pipe sucks the particles on the surface of the filter element into the transition pipe, and then connects the water pipe to the water branch pipe. The particles sucked into the transition pipe are flushed out of the water branch pipe under the action of the water flow and discharged from the slag outlet, thereby achieving a good cleaning effect on the filtering equipment.
