Description

Technical Field

[0001] The invention relates to the technical field of fertilizer fermentation equipment, and in particular to an organic fertilizer fermentation device and a use method thereof. Background Art

[0002] As a green and environmentally friendly agricultural production material, organic fertilizer has a significant effect on improving soil structure, increasing soil fertility, enhancing the resistance of crops to pests and diseases, and improving the quality of agricultural products. At a time when sustainable agricultural development is being advocated, its demand is growing.

[0003] The traditional organic fertilizer fermentation method mainly adopts the natural composting method, that is, organic waste such as livestock and poultry manure, crop straw, etc. are piled together and fermented and decomposed by microorganisms in nature. Although this method is low in cost, it has many disadvantages. For example, the fermentation cycle is long, usually taking several months or even longer, resulting in low production efficiency and difficulty in meeting the needs of large-scale agricultural production. Moreover, the natural composting process is greatly affected by environmental factors. Conditions such as temperature, humidity, and ventilation are difficult to accurately control, which easily causes uneven fermentation and incomplete fermentation of some raw materials, affecting the quality and fertilizer efficiency of fertilizers. At the same time, a large amount of odor and harmful gases will be generated during the natural composting process, which will pollute the surrounding environment, cause nutrient loss, and reduce the utilization rate of fertilizers.

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments. Unless otherwise defined, the technical terms or scientific terms used in the present invention should be the common meanings understood by people with ordinary skills in the field to which the present invention belongs. The above-mentioned features or features mentioned in the specific examples mentioned in the present invention can be combined arbitrarily, and these specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0023] Example 1 like Figure 1 As shown, the present invention provides an organic fertilizer fermentation device, including a raw material lifting unit 1, a pre-treatment unit 2 and a fermentation unit 3. The lifting frame 11 of the raw material lifting unit 1 is connected to the side wall of the pre-treatment box of the pre-treatment unit 2, and the pre-treatment box is connected to the fermentation tank 31 of the fermentation unit 3. A conveying mechanism 22 is provided below the raw material feed port 21 in the pre-treatment box, a mixing mechanism 23 is provided below the conveying mechanism 22, and the end of the conveying mechanism 22 is connected to the crushing mechanism 24. The crushing mechanism 24 is connected to the mixing mechanism 23 through a powder outlet pipe 246, and a microorganism mechanism 26 is provided above the crushing mechanism 24.

[0024] The raw material lifting unit 1 puts the raw material to be fermented into the pre-treatment unit 2. After the raw material to be fermented enters the pre-treatment box of the pre-treatment unit 2, the liquid in the raw material to be fermented leaks into the mixing mechanism 23 through the conveying mechanism 22. The filter pressing mechanism 25 squeezes the raw material to be fermented and squeezes the remaining liquid in the raw material to be fermented into the mixing mechanism 23. The solid raw material to be fermented enters the crushing mechanism 24 and is crushed into powder. The powdered solid fermentation raw material enters the mixing mechanism 23, and the obtained mixture finally enters the fermentation tank 31. The microbial liquid in the microbial mechanism 26 enters the fermentation tank 31 and is mixed with the mixture. The obtained fermentation liquid is fermented in the fermentation tank 31 to finally obtain a liquid fermentation product.

[0025] like Figure 2 and Figure 7 As shown, active lifting wheels 15 and driven lifting wheels 16 are respectively provided on both sides of the lifting hopper 12 of the raw material lifting unit 1, and the active lifting wheels 15 are slidably connected to the active lifting slide rail 13 of the lifting frame 11. The driven lifting wheels 16 are slidably connected to the driven lifting slide rail 14 of the lifting frame 11, and the driven lifting slide rail 14 is located between the active lifting slide rail 13 and the pre-processing box. The active lifting plate 17 of the lifting hopper 12 is connected to one end of the lifting steel wire, and the other end of the lifting steel wire is connected to the lifting motor at the top of the lifting frame 11.

[0026] The lifting motor starts to retract and release the lifting wire, and the lifting wire is connected to the active lifting plate 17 downward through the pulley on the top of the lifting frame 11. The lifting wire drives the lifting hopper 12 to move through the active lifting plate 17. When the lifting hopper 12 moves, the active lifting wheel 15 moves along the active slide rail, and at the same time, the driven lifting wheel 16 moves along the driven pulley. The outer cover of the lifting hopper 12 is provided with a rubber sleeve to prevent the liquid in the fermented raw material from leaking out from the gap of the lifting hopper 12.

[0027] The top of the driven lifting rail 14 is bent in the direction toward the raw material feed port 21, the active lifting shaft of the active lifting wheel 15 is connected to the active lifting plate 17, and the active lifting groove of the active lifting plate 17 is provided with a lifting shaft connected to the lifting wire.

[0028] The active lifting plate 17 moves under the drive of the lifting wire, and the movement of the active lifting plate 17 drives the lifting hopper 12. The shape of the driven lifting slide rail 14 is set to facilitate the active lifting wheel 15 to drive the driven lifting wheel 16 to move during the upward movement, and at the same time facilitate the lifting hopper 12 to flip forward to feed into the processing box.

[0029] like Figure 3 and Figure 5As shown, a filter press mechanism 25 is provided inside the pre-treatment box on one side of the raw material feed port 21, and a filter press cylinder 251 of the filter press mechanism 25 is connected to the top of the pre-treatment box, and the filter press cylinder 251 passes through the filter press block 252 and is connected to the filter press plate 253 in the filter press tank 254. The filter press tank 254 is located on one side of the filter press block 252 close to the conveying mechanism 22, and the filter press block 252 is slidably connected to the side wall of the filter press tank 254 through a slider assembly.

[0030] During the next feeding process after the lifting hopper 12 is loaded, the filter press mechanism 25 performs filter press treatment on the raw materials to be fermented after loading. During the filter press process, the conveyor belt 221 is in a stationary state to ensure the filter press effect on the raw materials to be fermented. The filter press cylinder 251 of the filter press mechanism 25 is started to drive the filter press plate 253 and the filter press block 252 to move, completing the filter press treatment of solid-liquid separation of the raw materials to be fermented on the conveyor belt 221.

[0031] When the filter press plate 253 moves upward, the slider on the filter press plate 253 moves to the top of the slide rail in the filter press tank 254, and then the filter press block 252 moves upward together with the filter press plate 253. During the downward movement of the filter press plate 253, the filter press block 252 moves downward together with the filter press plate 253 under the action of gravity, and moves downward until the fermented raw material enters the filter press tank 254 of the filter press block 252, and then the filter press plate 253 continues to move downward to squeeze the fermented raw material in the filter press tank 254 to remove the liquid therein. After the filtration is completed, the filter press plate 253 moves upward to drive the filter press block 252 to leave the solid fermented raw material.

[0032] A portion of the conveyor belt 221 of the conveying mechanism 22 is located below the raw material feed port 21, and another portion of the conveyor belt 221 is located below the filter press mechanism 25. Below the conveyor belt 221 is a mixing chamber 232 of the mixing mechanism 23. The conveyor belt 221 is evenly provided with a plurality of water leakage holes, and baffle plates 222 are provided on both sides of the conveyor belt 221.

[0033] The conveyor belt 221 has the same length as the mixing chamber 232. The leaking holes on the conveyor belt 221 filter the liquid in the fermented raw material into the mixing chamber 232. The baffle plate 222 prevents the fermented raw material from falling into the mixing chamber 232 on both sides of the conveyor belt 221 when the filter block 252 contacts the fermented raw material.

[0034] An inclined guide plate 242 is provided at the top of the crushing chamber 241 of the crushing mechanism 24, one end of the guide plate 242 contacts the conveyor belt 221, and the other end is located at the crushing feed port of the crushing chamber 241. A crushing cover plate 243 of the crushing feed port is connected to a crushing feed cylinder 244, a crushing pair of rollers 245 in the crushing chamber 241 is connected to a crushing motor, and the bottom of the crushing chamber 241 is arranged obliquely.

[0035] like Figure 6As shown, during the process that the inclined guide plate 242 contacts the conveyor belt 221 in the working state, the solid fermented raw materials on the conveyor belt 221 are shoveled into the crushing chamber 241. The setting of the guide plate 242 does not affect the normal operation of the conveyor belt 221. After the solid fermentation raw materials enter the crushing chamber 241, the crushing feed cylinder 244 is started, and the crushing feed cylinder 244 drives the crushing cover plate 243 to move above the crushing feed port to close the crushing chamber 241. The crushing motor is started, and the crushing motor drives the crushing roller 245 to crush the solid fermented raw materials to obtain powdered fermented raw materials. Since the bottom of the crushing chamber 241 is inclined, the powdered solid fermented raw materials enter the mixing chamber 232.

[0036] The bottom of the crushing chamber 241 can be made of a flexible material, which, combined with the vibrating eccentric structure in the prior art, facilitates the rapid discharge of the powder in the crushing chamber 241 .

[0037] A stirring assembly 231 is provided in the mixing chamber 232 of the mixing mechanism 23. The mixing chamber 232 is connected to the crushing chamber 241 through an inclined powder outlet pipe 246. A powder outlet butterfly valve is provided in the powder outlet pipe 246.

The stirring rods on the stirring rollers in the stirring assembly 231 are arranged at intervals, and the stirring rollers are meshed and connected through a gear assembly in the prior art. The stirring motor 32 is started to drive the active stirring roller to rotate, and the active stirring roller drives the driven stirring roller to rotate through the gear assembly, thereby achieving uniform mixing of the mixture in the mixing chamber 232 by the stirring assembly 231. The powder outlet butterfly valve controls whether the powder outlet pipe 246 puts powdered solid raw materials to be fermented into the mixing chamber 232, and accurately controls the amount of powder entering the mixing chamber. The powder outlet pipe 246 is tilted to facilitate rapid feeding into the mixing chamber 232.

[0039] The side wall of the microorganism chamber of the microorganism mechanism 26 is provided with a heating component 262, and the microorganism chamber is connected to the microorganism feed three-way of the fermentation tank 31 through a microorganism pump 261. The microorganisms can be propagated in the microorganism chamber, and the propagation temperature in the microorganism chamber is controlled by the heating component 262. The microorganism liquid is pumped into the fermentation tank 31 through the microorganism pump 261 to participate in the fermentation reaction.

[0040] like Figure 4As shown, a stirring motor 32 and a fermentation feed port are provided at the top of the fermentation tank 31, and the microorganism feed pipe 1 33 and the microorganism feed pipe 2 34 are both connected to the microorganism feed tee. The microorganism feed pipe 1 33 with a ring structure is horizontally arranged at the upper part of the fermentation tank 31, and the microorganism feed pipe 2 34 is vertically arranged in the fermentation tank 31. The stirring motor 32 is connected to the stirring shaft in the fermentation tank 31, and the stirring shaft is provided with stirring blades 35 from top to bottom.

[0041] The microbial liquid is pumped to the microbial feed tee by the microbial pump 261, and then enters the microbial feed pipe 1 33 and the microbial feed pipe 2 34 respectively. The microbial feed pipe 1 33 and the microbial feed pipe 2 34 are both provided with a plurality of liquid outlets, and the microbial liquid entering the microbial feed pipe 1 33 enters the fermentation tank 31 synchronously with the mixed material through the liquid outlets. The microbial liquid entering the microbial feed pipe 2 34 enters different heights of the fermentation liquid through the liquid outlets, so as to facilitate the uniform delivery or supplementation of the fermentation liquid at different positions.

[0042] A detection assembly is provided inside the fermentation tank 31, and the detection assembly includes a temperature sensor 37 inside the fermentation tank 31 and a pressure gauge 39 on the top of the fermentation tank 31. An exhaust valve 38 is provided on the top of the fermentation tank 31. The detection assembly monitors the fermentation condition in the fermentation tank 31, the temperature sensor 37 monitors the fermentation temperature of the fermentation liquid, the pressure gauge 39 monitors the pressure in the fermentation tank 31, and exhausts the air through the exhaust valve 38 to reduce the pressure.

[0043] A heating component 2 36 is provided on the side wall of the fermentation tank 31. Both the heating component 1 262 and the heating component 2 36 are spirally arranged water heat pipes. The heating component 1 262 and the heating component 2 36 control the temperature of the microorganism chamber and the fermentation tank 31 respectively.
