Description

Technical Field

[0001] The invention relates to the technical field of fermentation, in particular to a fermentation device for preparing water-soluble fertilizer. Background Art

[0002] Water-soluble fertilizers can contain all the nutrients needed for crop growth, such as nitrogen, phosphorus, potassium and various trace elements. Since water-soluble fertilizers can be completely soluble in water, crops can quickly absorb nutrients and the fertilizer effect is fast. In life, you can use kitchen waste to make water-soluble fertilizers. Soak kitchen waste such as vegetable leaves, fruit peels, and fish offal in water. After natural fermentation for about a month, filter out the residue and use it. In this process, fermentation can decompose organic matter, release more nutrients, and make the fertilizer easier for plants to absorb.

[0003] As disclosed in Chinese patent publication number CN220245988U, the utility model provides a sealed fermentation device for making water-soluble fertilizers, including a support frame, support legs, a fermentation tank, a first support rod, a water inlet pipe, a feed pipe, a funnel, a pluggable rotating material turning pipe structure, and a detachable cleaning filter cover structure, wherein the support legs are bolted to the four corners of the bottom end of the support frame. The sealing cover, driving motor, rotating tube, spiral plate, heating tube, second support rod, stirring rod, and discharge hole of the utility model cooperate with each other, which is conducive to driving the spiral plate to rotate through the rotating tube during the fermentation process, and turning the material during the rotation of the spiral plate, so that the material circulates inside the rotating tube during the turning of the material, and the material is heated by the heating tube during the rotation process, thereby improving the heating efficiency of the water-soluble fertilizer and thus improving the fermentation efficiency of the water-soluble fertilizer.

[0004] However, during the fermentation process, certain inorganic salts (such as calcium phosphate, calcium sulfate, etc.) may precipitate due to changes in solubility to form precipitates. These precipitates are generally very fine, and the precipitates will wrap up the nutrients, causing the yeast to be unable to fully absorb the required nutrients. During fermentation, this type of fermentation equipment stirs the fermentation liquid, but it cannot handle the fine precipitates close to the bottom of the fermentation device, which may clog the pipes and valves of the fermentation equipment, increasing the difficulty of cleaning and maintenance.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figures 1 to 8 The present invention provides a technical solution: a fermentation device for preparing water-soluble fertilizer, comprising a box body 1, an oxygen tank 2 is fixedly installed on the top of the box body 1, a sleeve 4 is rotatably installed in the center of the box body 1, a sleeve 3 is rotatably installed on the outer wall of the sleeve 4, a scraper 5 is rotatably installed on the outer wall of the sleeve 3, a mounting body 6 is rotatably installed on the inner wall of the sleeve 3, the mounting body 6 is coaxially fixedly installed with the scraper 5, and a first protrusion 7 is fixedly installed at one end of the mounting body 6 away from the scraper 5, a slide groove 8 is opened on the outer wall of the sleeve 3 to enable the first protrusion 7 to slide inside, and the slide groove 8 is composed of two transverse grooves and two inclined grooves connected alternately;

[0033] Also includes a drive assembly capable of causing the sleeve 3 to continuously rotate;

[0034] It also includes a rotating assembly that can make the sleeve 4 rotate intermittently.

[0035] When the device is used, vegetable leaves, fruit peels, fish viscera and other kitchen waste are placed inside the box 1, and water is introduced into the box 1. When the raw materials and fermentation liquid inside the box 1 need to be stirred, the sleeve 3 is driven to rotate continuously by the driving component. Figure 4 During the rotation of the sleeve 3, the scraper 5 will be driven to rotate, and the first protrusion 7 will slide in the chute 8. When the first protrusion 7 slides to the inclined groove in the chute 8 with an upward angle, the scraper 5 will rotate along the axis until one side of the scraper 5 coincides with the bottom of the box body 1. At this time, the scraper 5 will sweep the sediment and raw materials at the bottom of the box body 1 during the rotation, and can scrape and collect the fine sediment at the bottom of the box body 1. When the first protrusion 7 slides to the inclined groove in the chute 8 with an downward angle, the scraper 5 will be reset. During the reset process, the scraper 5 will flip the raw materials at the bottom of the box body 1 upward and lift them up, so that the fine sediment accumulated at the bottom of the box body 1 floats in the water inside the box body 1, thereby preventing the yeast at the bottom from not getting enough oxygen, which can significantly improve the fermentation effect of the raw materials and reduce the fermentation time.

[0036] In this process, by rotating the sleeve 4 intermittently through the rotating assembly, the position of the scraper 5 on the bottom of the box body 1 can be changed, so that the bottom of the box body 1 can be fully cleaned to prevent local accumulation of raw materials and precipitation, and ensure that nutrients are evenly distributed in the fermentation liquid to avoid local nutrient deficiency, thereby promoting uniform growth of yeast.

[0037] It is worth mentioning that the outer wall of the scraper 5 on the side in contact with the bottom of the box 1 is set to be pointed, which can more effectively clean the smaller sediments accumulated at the bottom of the box 1 and prevent the fine sediments from adhering to the bottom of the box 1 and affecting the subsequent fermentation process.

[0038] Furthermore, the driving assembly includes a motor fixed on the top of the box body 1 , the output shaft of the motor passes through the top of the box body 1 and is fixedly mounted with a first gear 15 , a second gear 16 is fixedly mounted on the outer wall of the sleeve 3 , and the second gear 16 meshes with the first gear 15 .

[0039] See also Figure 5 as well as Figure 6 When the fermentation liquid needs to be stirred, the first gear 15 is driven by the driving motor to rotate, thereby driving the second gear 16 to rotate, and then the sleeve 3 is driven to rotate through the second gear 16, so as to achieve the purpose of continuous rotation of the sleeve 3, so that the scraper 5 can continuously turn over the raw materials accumulated at the bottom of the box body 1, and make the fine sediment at the bottom of the box body 1 float in the fermentation liquid.

[0040] Furthermore, the rotating assembly includes a transmission wheel 10 fixedly mounted on the outer wall of the motor output shaft, the outer wall of the transmission wheel 10 is provided with an opening, a mounting rod 11 is coaxially fixedly mounted on the bottom of the transmission wheel 10, a second protrusion 12 is fixedly mounted on the top of the mounting rod 11, and the second protrusion 12 is located between the openings of the transmission wheel 10, a rotating body 9 is fixedly mounted on the outer wall of one end of the sleeve 4 extending out of the sleeve 3, a plurality of notches 13 that can fit with the circular outer wall of the transmission wheel 10 are provided on the outer wall of the rotating body 9, and a straight groove 14 that can allow the second protrusion 12 to slide inside is provided between two adjacent notches 13.

[0041] See also Figure 6 When the motor drives the first gear 15 to rotate, it will also drive the transmission wheel 10 to rotate. The process of the transmission wheel 10 rotating is divided into two stages. In the first stage, the circular outer wall of the transmission wheel 10 fits with the notch 13 to keep the rotating body 9 stationary. When the circular outer wall of the transmission wheel 10 separates from the notch 13, it is the second stage. In the second stage, the second protrusion 12 will slide into the straight groove 14, and during the rotation of the transmission wheel 10, the second protrusion 12 will drive the rotating body 9 to rotate until the circular outer wall of the transmission wheel 10 fits with the notch 13 again, so that the rotating body 9 remains stationary, so as to achieve the purpose of intermittent rotation of the rotating body 9, so that the position of the scraper 5 on the bottom of the box body 1 is changed, so that the bottom of the box body 1 can be cleaned in all directions to prevent local accumulation of raw materials and sediments. By turning the raw materials and processing the sediments, the fluidity of the fermentation liquid can be increased, the transfer efficiency of oxygen and nutrients can be improved, thereby improving the fermentation efficiency, and it can also ensure that the nutrients are evenly distributed in the fermentation liquid to avoid local nutrient deficiency, thereby promoting the uniform growth of yeast.

[0042] Furthermore, a mounting plate 18 is fixedly installed on the inner wall of the box body 1, and a piston body 19 is fixedly installed on the top of the mounting plate 18, a piston plate 20 is slidably installed inside the piston body 19, and the piston plate 20 divides the inside of the piston body 19 into two cavities, a rotating rod 21 is rotatably installed at the bottom of the first gear 15, and a piston rod 22 is rotatably installed at the bottom of the rotating rod 21, one end of the piston rod 22 passes through the outer wall of the piston body 19 and is fixedly connected to the piston plate 20, and the piston rod 22 is slidably connected to the penetration point of the outer wall of the piston body 19, a first air intake pipe 23 is connected between the outer wall of the piston body 19 and the oxygen tank 2, and the first air intake pipe 23 can only transport gas into the piston body 19, and the outer wall of the piston body 19 is also connected to an exhaust channel that can exhaust gas unidirectionally into the fermentation liquid.

[0043] See also Figure 5 During the rotation of the first gear 15, the rotating rod 21 will be driven to rotate. During the rotation of the rotating rod 21 along with the first gear 15, the piston rod 22 will drive the piston plate 20 to move back and forth. During the reciprocating movement of the piston plate 20, oxygen can be extracted from the oxygen tank 2 and transported to the inside of the box body 1 through the exhaust channel to improve the metabolic efficiency of the microorganisms, so that they can more effectively decompose the substrate and generate the required fermentation products.

[0044] Furthermore, the exhaust channel includes an air storage chamber 25 opened inside the outer wall of the box body 1, and the cavity inside the piston body 19 close to the outer wall of the box body 1 is connected to the inside of the air storage chamber 25 through a first connecting pipe 24, and the first connecting pipe 24 can only transport gas from the piston body 19 to the air storage chamber 25. A plurality of first air outlets 26 connected to the inside of the air storage chamber 25 are annularly opened on the inner wall of the box body 1.

[0045] See also Figure 5 The piston plate 20 reciprocates left and right in the piston body 19 to extract oxygen from the oxygen tank 2, and then injects it into the air storage chamber 25 through the first connecting pipe 24, so that the oxygen in the air storage chamber 25 is transported to the inside of the box body 1 through the first air outlet 26, which not only achieves the purpose of injecting oxygen into the fermentation liquid, but also can blow the tiny sediments raised by the scraper 5, so that they can float in the fermentation liquid for a longer time, prolonging the time for them to settle again, and blowing air inward in a circular manner on the inner wall of the box body 1 can make the nutrients evenly distributed in the fermentation liquid, avoid local nutrient deficiency, and thus promote the uniform growth of yeast.

[0046] Furthermore, a plurality of collecting holes 27 are annularly opened on the outer wall of the sleeve 3, and an isolation plate 28 is fixedly installed on the outer wall of the sleeve 4. The isolation plate 28 divides the space formed by the inner wall of the sleeve 3 and the outer wall of the sleeve 4 into two layers of space, and the outer wall of the isolation plate 28 is rotatably connected to the inner wall of the sleeve 3.

[0047] See also Figure 5 The sealed space formed by the inner wall of the sleeve 3 and the outer wall of the sleeve 4 is divided into two layers, an upper layer and an lower layer, by an isolation plate 28, and a plurality of collecting holes 27 are provided in a ring-shaped outer wall of the sleeve 3. When the scraper 5 lifts up the tiny sediments deposited at the bottom of the box body 1, oxygen is blown to the sleeve 3 through the first air outlet 26 provided in a ring-shaped manner, so that the lifted tiny sediments can enter the upper space inside the sleeve 3 through the collecting holes 27 to achieve the purpose of collecting them. Isolating the sediments can prevent them from accumulating at the bottom of the fermentation tank, thereby avoiding the possible formation of anaerobic areas, which is particularly important for fermentation processes that require good oxygen transfer. By limiting the sediments to a specific area, their contact with microorganisms can be reduced, thereby reducing the inhibitory effect that the sediments may produce, and isolating the sediments can make the monitoring and control of the fermentation process more precise.

[0048] Furthermore, a fixing rod 30 is rotatably mounted on the inner wall of the sleeve 4, a pressure chamber is provided inside the fixing rod 30, and the pressure chamber is communicated with the lower space inside the sleeve 3, the cavity inside the piston body 19 away from the outer wall of the box body 1 is also communicated with the interior of the oxygen tank 2 through the first air inlet pipe 23, the cavity inside the piston body 19 away from the outer wall of the box body 1 is communicated with the pressure chamber inside the fixing rod 30 through the second connecting pipe 31, and the second connecting pipe 31 can only transport gas to the pressure chamber inside the fixing rod 30;

[0049] A third air outlet duct 29 is provided at the axis of the mounting body 6 and the scraper 5 . The third air outlet duct 29 can transport the air in the lower space inside the sleeve 3 to the box body 1 .

[0050] See also Figure 5 as well as Figure 8 By reciprocating the piston plate 20 in the piston body 19, the oxygen extracted from the oxygen tank 2 can be transported to the pressure chamber inside the fixed rod 30, and then to the lower space inside the sleeve 3, and then blown out from the edge of the scraper 5 through the mounting body 6, so as to sweep the inner wall between the outer wall of the scraper 5 and the box body 1, thereby preventing tiny particles from gathering at the bottom edge of the box body 1 and burying the yeast.

[0051] It is worth mentioning that on this basis, a blowing hole can be opened at the rotating point of the scraper 5 and the sleeve 3 to blow the edges of the outer walls of the scraper 5 and the sleeve 3 to prevent tiny sediments from accumulating in the blind spot of the scraper 5's trajectory, so as to achieve the turning and lifting of the fine sediments at the bottom of the box 1 without dead angles.

[0052] Furthermore, the outer wall of the fixing rod 30 is provided with a plurality of first air holes 32 communicating with the pressure chamber, the outer wall of the sleeve 4 is provided with a plurality of second air holes 33 penetrating the outer wall of the sleeve 4 , and the second air holes 33 can be intermittently communicated with the first air holes 32 .

[0053] See also Figure 7 Under normal conditions, the second air hole 33 is offset from the first air hole 32, so that the oxygen entering the pressure chamber in the fixing rod 30 is less than the oxygen delivered to the lower space of the sleeve 3, so that the pressure chamber in the fixing rod 30 maintains a high pressure state.

[0054] When the sleeve 4 rotates intermittently, the second air hole 33 and the first air hole 32 will completely overlap for a moment. Under the action of high pressure, the oxygen in the pressure chamber in the fixed rod 30 will quickly pass into the lower space in the sleeve 3, and then quickly spray into the interior of the box body 1 from the third air outlet pipe 29. By increasing the injection speed, the stubborn sediment adhering to the inner wall of the box body 1 can be purged to prevent it from adhering to the inner wall of the box body 1 and causing trouble for subsequent cleaning.

[0055] Furthermore, a feed port 17 is provided at the top of the box body 1, and the feed port 17 is communicated with the lower part of the mounting plate 18. A discharge port is provided at the bottom of the box body 1, and a filter screen and a solenoid valve are installed at the discharge port.

[0056] When it is necessary to make water-soluble fertilizer, raw materials, water, yeast, etc. are put into the box 1 through the feed port 17. When the fermentation is completed, it can be taken out from the discharge port at the bottom of the box 1. Under the action of the filter, the prepared water-soluble fertilizer will be separated from other objects.

[0057] Furthermore, the hole of the collecting hole 27 gradually decreases from the outside to the inside.

[0058] See also Figure 5 After the scraper 5 lifts up the tiny sediments, the air delivered through the first air outlet 26 blows the lifted tiny sediments into the upper space inside the sleeve 3 through the collecting hole 27. The cavity of the collecting hole 27 gradually decreases from the outside to the inside, which can make it easier for the sediments to enter the sleeve 3, but it is more difficult to escape from the sleeve 3, thereby preventing the collected sediments from escaping into the sleeve 3 again through the collecting hole 27.

[0059] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
