Description

Technical Field

[0001] This invention relates to the field of water-soluble fertilizer production technology, and in particular to a water-soluble fertilizer production line process. Background Technology

[0002] Medium-element water-soluble fertilizers are soluble fertilizers mainly composed of calcium, magnesium, and sulfur. They are multi-element compound fertilizers that can be completely dissolved in water. They can dissolve quickly in water and are more easily absorbed by crops. More importantly, they can be used in facility agriculture such as sprinkler and drip irrigation to achieve integrated water and fertilizer management, thus saving water, fertilizer, and labor. Among them, calcium fertilizers mainly use water-soluble inorganic calcium salts and chelated calcium. The raw materials for the products can be calcium chloride, calcium nitrate, calcium ammonium nitrate, calcium acetate, and calcium chelated with organic substances such as EDTA, citric acid, amino acids, and sugar alcohols.

[0003] Currently, stainless steel pipe pickling wastewater, after being treated by physicochemical processes such as acid-base neutralization, coagulation, and adsorption, is analyzed by compositional analysis. The main components include inorganic ions, namely a large amount of calcium and nitrate ions, and small amounts of sulfate and sodium ions; it also includes small amounts of small organic molecules such as PAM. Among these, calcium nitrate (≥500 g / L) is the main component, a key component of water-soluble calcium fertilizer. For the preparation of water-soluble calcium fertilizer, the wastewater first needs to be concentrated to obtain a Ca(NO3)2 concentrate. Then, nitric acid is added to the Ca(NO3)2 concentrate and stirred to adjust the pH value. A bacterial agent is also added to the solution and stirred. After stirring, the solution is allowed to ferment. After a certain time, the mixture is stirred and allowed to ferment. Finally, the upper liquid is filtered and bottled to obtain the finished water-soluble calcium fertilizer. Traditional stirring methods mainly rely on a motor to drive the stirring shaft inside the tank to rotate. Since the stirring shaft is located at the center of the tank and rotates in a single direction, the constant rotation speed of the stirring shaft causes vortices to form in the solution inside the tube. Under the action of rotational force, the solution adheres to the inner wall of the tank and rotates and mixes. Moreover, the rotational state of the solution with the stirring shaft tends to be stable, resulting in poor mixing effect of the components inside the solution. This makes it difficult to improve the mixing effect and efficiency of the components in the solution. In view of this, we propose a water-soluble fertilizer production line process. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, adapt to practical needs, and provide a water-soluble fertilizer production line process to solve the technical problem that it is not convenient to improve the mixing effect and efficiency of the components in the solution during the stirring of the current batching tank.

[0005] To achieve the objective of this invention, the technical solution adopted by this invention is as follows: designing a water-soluble fertilizer production line process, the production line process being based on a production stirring device, the production stirring device including a mixing tank body, and the mixing tank body having a stirring kit inside;

[0006] A sealing lid is detachably placed on the top of the ingredient tank body, and a motor frame is fixedly installed in the center of the top of the sealing lid. A drive motor is detachably installed on the top of the motor frame.

[0007] The stirring kit includes a symmetrically arranged planetary gear set, and the drive motor is used to drive the planetary gear set to operate.

[0008] The planetary gear set includes an internal gear ring with a sun gear centrally located inside. Teeth are arranged on the inner edge surface of the internal gear ring. Planet gears are arranged in a ring array meshing on the outer edge surface of the sun gear. The planet gears mesh with the teeth on the inner edge surface of the internal gear ring. A lead screw body is coaxially and fixedly connected between the sun gears. A connecting shaft is arranged between the planet gears located in the same vertical axis direction. A stirring component is movably arranged on the outer edge surface of the lead screw body. A disc is constructed on the lower end face of the internal gear ring in the planetary gear set located at the bottom. A stirring motor is centrally and fixedly installed at the bottom of the mixing tank body. The shaft of the stirring motor extends into the mixing tank body and is coaxially and fixedly fixed to the disc in the planetary gear set located at the bottom.

[0009] The stirring assembly includes a main gear with a through hole structure at the axial position. A slider that can be movably meshed with the outer edge surface of the lead screw body is fixedly installed inside the through hole of the main gear. A secondary gear is installed in a ring array on the outer edge surface of the main gear. The interior of the secondary gear is a hollow body. A sleeve that can be movably sleeved on the outer edge surface of the connecting shaft is fixedly installed inside the hollow body. The bottom end of the sleeve is fixedly connected to the stirring structure.

[0010] The water-soluble fertilizer production line process includes the following steps:

[0011] S100, Loading process:

[0012] Natural water is drawn into the heat exchanger and then enters the insulated water tank.

[0013] S200, Fermentation Process:

[0014] S201, Downward Swirling Stirring: Take natural water from the insulated water tank and introduce it into the main body of the ingredient tank. Add yeast and lactic acid bacteria powder in a 1:1 weight ratio into the main body of the ingredient tank. After the yeast and lactic acid bacteria powder come into contact with the natural water in the main body of the ingredient tank, they are suspended on the surface of the natural water and slowly dissolve and sink. At this time, the drive motor is started, which makes the sun gear rotate and drive the planet gear and the lead screw to rotate, thereby causing the entire stirring component to move downward. After the stirring component moves to the lower position, the drive motor is turned off and the stirring motor is started. Under the action of the stirring motor, the disc and the inner gear ring are rotated. The sun gear remains stationary due to the drive motor. During the rotation of the inner gear ring, the planet gear is rotated, thereby causing the connecting shaft to rotate. The stirring structure is suspended in the lower position and rotates, forming a negative pressure vortex at the lower position of the ingredient tank. This causes the bacteria powder suspended on the surface of the natural water to sink quickly and mix with the natural water. After stirring is completed, let it stand for fermentation.

[0015] S202, Top-Swirl Stirring: Add Bacillus licheniformis and Bacillus subtilis powder in a 1:1 weight ratio into the main body of the mixing tank. After settling in S201, there is sediment at the bottom of the mixing tank. At this time, reverse the start of the drive motor to move the stirring assembly upward. After the stirring assembly moves to the upper position, turn off the drive motor and start the stirring motor. Under the action of the stirring motor, the stirring structure is suspended in the upper position and rotates, forming a negative pressure vortex at the upper position of the mixing tank. At this time, the sediment at the bottom of the mixing tank rises under the action of negative pressure, while the Bacillus licheniformis and Bacillus subtilis powder on the surface of the natural water moves downward, so that the sediment and the powder collide, merge and stir with each other. After stirring is completed, let it stand for fermentation.

[0016] S300, Finished Product Filling:

[0017] After the fermentation inside the mixing tank is completed, the mixture is placed into a settling tank for settling. After settling, the clear liquid from the top is placed into the finished product tank to obtain water-soluble calcium fertilizer.

[0018] Preferably, the stirring structure includes a second sleeve fixedly connected to the bottom end of the first sleeve and movably sleeved on the outer edge of the connecting shaft. Stirring blades are arranged in a ring array on the outer edge of the bottom end of the second sleeve. The stirring blades on the same outer edge of the second sleeve are staggered in the direction of the central axis. Threaded teeth are formed on the outer edge of the second sleeve. A groove adapted to abut against the threaded teeth is opened at the end of the stirring blade facing the second sleeve. The stirring blade is welded and fixed to the second sleeve and the threaded teeth.

[0019] Preferably, a connecting block one is centrally located at the top of the sun gear, a connecting block two is centrally located at the top of the planet gear, and a plug rod one is centrally located at the bottom of the sun gear. A connecting plate is movably mounted in a ring array on the outer edge of the plug rod one, and a linkage disc is connected to the end of the connecting plate away from the plug rod one.

[0020] Preferably, a second insert rod is centrally located on the lower end face of the planetary gear. The end of the second insert rod away from the planetary gear is rotatably connected to the linkage disc. Both ends of the lead screw body are fixedly connected to the first connecting block and the first insert rod, respectively. Both ends of the connecting shaft are fixedly connected to the second connecting block and the second insert rod, respectively.

[0021] Preferably, the top outer edge of the slider is provided with a connecting frame plate in a ring array, and the top and bottom outer edges of the slider are provided with a ring-shaped T-shaped groove. One end of the connecting frame plate is constructed with a T-shaped slider that can be rotatably installed in the T-shaped groove, and the other end of the connecting frame plate is fixedly connected to the sleeve.

[0022] Preferably, the bottom outer edge of the slider is provided with a connecting frame plate two in a circular array. One end of the connecting frame plate two is also constructed with a T-shaped slider that can be rotatably installed in the T-shaped groove, and the other end of the connecting frame plate two is fixedly connected to the sleeve two.

[0023] Preferably, the bottom of the mixing tank body is provided with support legs arranged in a circular array. The top of the support legs is connected to the mixing tank body structure, and the bottom of the support legs is connected with an anti-slip base plate. A temperature sensor connected to the inside of the mixing tank body and used for temperature detection is provided at the bottom of the outer edge surface of the mixing tank body.

[0024] Preferably, the outer edge of the sealed container cover is provided with a feed inlet, the top of the feed inlet is movably covered with a feed cover, the top of the sealed container cover is provided with a vent hole, a vent pipe is fixedly installed in the vent hole, and a vent valve for controlling the venting is installed in the vent pipe.

[0025] Preferably, the bottom end of the drive motor shaft extends into the sealed tank cover and is detachably connected to the connecting block 1, and is used to control the rotation of the connecting block 1.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] 1. By setting up a planetary gear set and a stirring assembly, the planetary gear set is driven by a drive motor, which in turn rotates the sun gear. The meshing of the sun gear and planetary gears, as well as the meshing of the planetary gears with the gear teeth, achieves synchronous rotation of the planetary gears, which in turn causes the connecting shaft to rotate synchronously. The synchronous rotation of the connecting shaft drives the stirring structure to rotate, thereby achieving stirring and mixing of the solution in the mixing tank. The planetary structure of the planetary gear set drives multiple stirring structures to rotate and stir. The stirring position is off the axis of the mixing tank body, so the solution is less likely to have vortex phenomena, which is beneficial to improving the mixing effect and efficiency of the components in the solution.

[0028] 2. By setting up a slider and a lead screw body, the rotation of the sun gear will drive the lead screw body to rotate, thereby causing the slider engaged with the lead screw body to move. This, in turn, drives the entire mixing assembly to move in the axial direction of the lead screw body, realizing the change of the mixing structure in the height direction. Thus, the position of the mixing structure in the height direction can be adjusted according to the most efficient mixing position during the initial addition and subsequent addition of bacterial powder.

[0029] 3. By constructing threaded teeth on the outer edge of sleeve two and opening grooves on the stirring blade to fit the threaded teeth, the stirring blade is welded and fixed to sleeve two and threaded teeth. During the rotation of the stirring structure, the setting of threaded teeth helps to enhance the structural strength of the connection between the stirring blade and sleeve two, thereby maintaining the stability of the stirring structure operation.

[0030] 4. By staggering the stirring blades on the outer edge of the same sleeve along the central axis, while the stirring structure rotates, the stirring blades have their own stirring range due to the height difference in the stirring direction. Furthermore, the stirring ranges of multiple stirring blades overlap, thus making it less likely to generate vortices during stirring and increasing the degree of local solution disorder, thereby improving the stirring effect.

A sealing tank cover 5 is detachably placed on the top of the batching tank body 1. A motor frame 8 is fixedly mounted in the center of the top of the sealing tank cover 5. A drive motor 9 is detachably mounted on the top of the motor frame 8. The mixing assembly 10 includes symmetrically arranged planetary gear sets 11. Two planetary gear sets 11 are respectively arranged inside the sealing tank cover 5 and the batching tank body 1. Both the mixing tank body 1 and the planetary gear carrier are provided inside for mounting the planetary gear set 11. The drive motor 9 is used to drive the planetary gear set 11 to rotate. The planetary gear set 11 includes an internal gear ring 1101 with a sun gear 1102 centrally located inside. Teeth are arranged on the inner edge surface of the internal gear ring 1101. Planet gears 1104 are arranged in a ring array on the outer edge surface of the sun gear 1102. The planet gears 1104 mesh with the teeth on the inner edge surface of the internal gear ring 1101. The two sun gears 1102 are coaxially fixed. A connecting shaft 1001 is provided between planetary gears 1104 located on the same vertical axis and connected to a lead screw body 1002. A stirring assembly 12 is movably mounted on the outer edge of the lead screw body 1002. A disc is constructed on the lower end face of the internal gear ring 1101 in the planetary gear set 11 located at the bottom. A stirring motor is fixedly installed in the center of the bottom of the mixing tank body 1. The shaft of the stirring motor extends into the mixing tank body 1 and is coaxially fixed with the disc in the planetary gear set 11 located at the bottom. Component 12 includes a main gear 1201 with a through hole structure at the axial position. A slider 1202 that can be movably meshed with the outer edge surface of the lead screw body 1002 is fixedly installed inside the through hole of the main gear 1201. A secondary gear 1205 is meshed in a ring array on the outer edge surface of the main gear 1201. The interior of the secondary gear 1205 is a hollow body.

A stirring structure is fixedly connected to the bottom end of the sleeve 1204.

[0042] Example 2: Water-soluble fertilizer production line process, including the following steps:

[0043] S100, Loading process:

[0044] Natural water is drawn into the heat exchanger and then enters the insulated water tank.

[0045] S200, Fermentation Process:

[0046] S201, Downward Swirling Stirring: Take natural water from the insulated water tank and introduce it into the ingredient tank body 1. Add yeast and lactic acid bacteria powder in a 1:1 weight ratio into the ingredient tank body 1. After the yeast and lactic acid bacteria powder come into contact with the natural water in the ingredient tank body 1, they suspend on the surface of the natural water and slowly dissolve and sink. At this time, start the drive motor 9 to make the sun gear 1102 rotate, which drives the planet gear 1104 and the lead screw body 1002 to rotate, thereby causing the stirring assembly 12 to move downward as a whole. After the stirring assembly 12 moves to the lower position, turn off the drive motor. 9. Start the stirring motor. Under the action of the stirring motor, the disc and the inner gear ring 1101 will rotate. The sun gear 1102 will remain stationary due to the limitation of the driving motor 9. During the rotation of the inner gear ring 1101, the planetary gear 1104 will rotate, thereby causing the connecting shaft 1001 to rotate. This will cause the stirring structure to rotate while suspended in the lower position, and a negative pressure vortex will be formed in the lower position of the mixing tank body 1. This will cause the bacterial powder suspended on the surface of the natural water to sink quickly and be mixed with the natural water. The stirring time is 20 minutes. After stirring, the mixture will be left to ferment for 5 hours.

[0047] S202, Top-Swirl Stirring: Add Bacillus licheniformis and Bacillus subtilis powder in a weight ratio of 1:1 into the main body 1 of the mixing tank. After settling in S201, sediment exists at the bottom of the main body 1 of the mixing tank. At this time, reverse the start of the drive motor 9, so that the stirring component 12 moves upward as a whole. After the stirring component 12 moves to the upper position, turn off the drive motor 9 and start the stirring motor. Under the action of the stirring motor, the stirring structure is suspended in the upper position and rotates, forming a negative pressure vortex at the upper position of the main body 1 of the mixing tank. At this time, the sediment at the bottom of the main body 1 of the mixing tank rises under the action of negative pressure, while the Bacillus licheniformis and Bacillus subtilis powder on the surface of the natural water moves downward, so that the sediment and the powder collide and merge with each other. The stirring time is 20 minutes. After stirring, let it stand for fermentation for 48 hours.

[0048] S300, Finished Product Filling:

[0049] After the fermentation inside the mixing tank 1 is completed, it is put into the settling tank for settling. After settling, the clear liquid at the top is taken and placed into the finished product tank to obtain water-soluble calcium fertilizer.

[0050] To enhance the local turbulence of the solution during stirring in a stirred structure, see [reference needed].

Stirring blades 1207 are arranged in a ring array on the bottom outer edge of the second sleeve 1206. The stirring blades 1207 on the same outer edge of the second sleeve 1206 are staggered in the direction of the central axis. Threaded teeth 1209 are constructed on the outer edge of the second sleeve 1206. A groove adapted to abut against the threaded teeth 1209 is opened at one end of the stirring blade 1207 facing the second sleeve 1206. The stirring blade 1207 is welded and fixed to the second sleeve 1206 and the threaded teeth 1209.

[0051] To improve the stability of the mixing kit 10 during operation, please refer to... Figures 4 to 7 A connecting block 1103 is centrally located at the top of the sun gear 1102, and a connecting block 2 1105 is centrally located at the top of the planet gear 1104. A first insertion rod 1106 is centrally connected to the bottom of the sun gear 1102. A connecting plate 1109 is movably mounted in a ring array on the outer edge of the first insertion rod 1106. A linkage disc 1107 is connected to the end of the connecting plate 1109 away from the first insertion rod 1106. A second insertion rod 1108 is centrally located on the lower end face of the planet gear 1104. The end of the second insertion rod 1108 away from the planet gear 1104 is rotatably connected to the linkage disc 1107. The two ends of the lead screw body 1002 are fixedly connected to the first connecting block 1103 and the first insertion rod 1106, respectively. The two ends of the connecting shaft 1001 are fixedly connected to the first connecting block 1103 and the first insertion rod 1106, respectively. Connecting blocks 1105 and 1108 are fixedly connected. Connecting brackets 1203 are arranged in a ring array on the outer edge of the top end of slider 1202. T-shaped grooves 13 are opened in a ring on the outer edge of the top and bottom ends of slider 1202. One end of connecting bracket 1203 is equipped with a T-shaped slider that can be rotatably installed in the T-shaped groove 13. The other end of connecting bracket 1203 is fixedly connected to sleeve 1204. Connecting brackets 1208 are arranged in a ring array on the outer edge of the bottom end of slider 1202. One end of connecting bracket 1203 is also equipped with a T-shaped slider that can be rotatably installed in the T-shaped groove 13. The other end of connecting bracket 1208 is fixedly connected to sleeve 1206.

[0052] See Figure 1 and Figure 4The bottom of the mixing tank body 1 is provided with a ring-shaped array of support legs 3. The top of the support legs 3 is structurally connected to the mixing tank body 1, and the bottom of the support legs 3 is connected to an anti-slip base plate 4. A temperature sensor 2 is provided on the bottom of the outer edge of the mixing tank body 1, which is connected to the interior of the mixing tank body 1 and is used to detect the temperature. A feed inlet is provided on the outer edge of the sealing tank cover 5. A feed cover 7 is movably covered on the top of the feed inlet. An exhaust hole is provided on the top of the sealing tank cover 5. An exhaust pipe 6 is fixedly installed in the exhaust hole. An exhaust valve for controlling the exhaust is provided in the exhaust pipe 6. The bottom end of the shaft of the drive motor 9 extends into the sealing tank cover 5 and is detachably connected to the connecting block 1103 and is used to control the rotation of the connecting block 1103. This invention solves the technical problem that it is not convenient to improve the mixing effect and efficiency of the components in the solution when the mixing tank is stirred by setting the stirring kit 10.

[0053] Working principle: In use, the feed cover 7 can be opened, and each component can be added into the mixing tank body 1. Then, by starting the drive motor 9, the shaft of the drive motor 9 drives the sun gear 1102 to rotate. Through the meshing of the sun gear 1102 and the planet gears 1104, and the meshing of the planet gears 1104 with the gear teeth, the planet gears 1104 rotate synchronously, thereby causing the connecting shaft 1001 to rotate synchronously. The synchronous rotation of the connecting shaft 1001 drives the stirring structure to rotate, thus realizing the stirring and mixing of the solution in the mixing tank body 1. While the sun gear 1102 rotates, it also drives the lead screw body 1002 to rotate. This causes the slider 1202 engaged with the lead screw body 1002 to move, thereby driving the entire stirring assembly 12 to move along the axial direction of the lead screw body 1002. This achieves a change in the height of the stirring structure, which allows for thorough stirring of the solution at various height positions within the mixing tank body 1. While the stirring structure rotates, due to the height difference of the stirring blades 1207, each stirring blade 1207 has its own stirring range, and the stirring ranges of multiple stirring blades 1207 overlap. Therefore, vortices are less likely to be generated during stirring, while also increasing the degree of local solution disorder.

[0054] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
