[0001] The present invention relates to the technical field of polyglutamic acid-based water-soluble fertilizer production equipment, and particularly to a polyglutamic acid-based water-soluble fertilizer concentration processing equipment and method. Background Art

[0002] In modern agriculture, water-soluble fertilizers are widely used due to their high efficiency and easy absorption. Especially polyglutamic acid-based water-soluble fertilizers are increasingly favored by the market because of their unique nutritional components and significant promotion effect on crop growth. However, in the production process of polyglutamic acid-based water-soluble fertilizers, especially in the concentration processing link, a series of technical challenges are faced.

[0003] Traditional water-soluble fertilizer mixing methods mainly rely on simple stirring devices. When dealing with a large amount of powdery raw materials, this method often causes the powder to float on the liquid surface and is difficult to mix evenly, affecting the uniformity and quality of the final product. In addition, long-term static placement may cause the material to precipitate and agglomerate, further reducing the utilization rate of the effective components of the fertilizer. These deficiencies not only limit the improvement of product quality but also increase the complexity and cost of the production process. Therefore, a polyglutamic acid-based water-soluble fertilizer concentration processing equipment and method are needed to solve the above problems. Summary of the Invention

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] 1. Through the synergistic action of the pressure roller, dispersion paddle and scraping paddle in the mixing mechanism of the present invention, the problems of powder floating, uneven mixing and precipitation caking in traditional stirring are solved. The pressure roller rotates around its own axis while revolving around the shaft through the meshing transmission of the first tooth umbrella and the second tooth umbrella, and presses the surface powder into the liquid; the dispersion paddle is driven by the first gear and the second gear to rotate at high speed to refine and disperse the raw materials in the liquid; the scraping paddle rotates along the inner wall of the tank body to shovel up the sediment at the bottom. This combined structure significantly improves the mixing uniformity, avoids caking, ensures sufficient chelation reaction of the fertilizer, and finally the product quality is stable.

[0024] 2. By setting a feeding mechanism at the upper end of the main body of the reaction kettle, the present invention solves the problems of low manual feeding efficiency and raw material caking. The filter screen is fixed by bolts to intercept caked materials. The auger rod is driven by the first motor to evenly transport the screened raw materials into the reaction kettle. This design not only saves manpower, but also avoids large particle materials from entering the reaction kettle and affecting the mixing efficiency. At the same time, the chute of the transmission shaft sleeve is closed by the sliding sleeve, the sealing sleeve and the turntable to prevent the liquid from seeping into the internal structure, simplifies the equipment cleaning process, and further ensures the stability of continuous production.

[0025] 3. Through the design of the sealing sleeve and the sliding sleeve, the present invention solves the problems of gear corrosion and difficult equipment cleaning. The sealing sleeve isolates the gear from the liquid, avoiding rust and wear. The hollow structure of the pressure roller enables it to float adaptively with the liquid level to meet different production requirements. In addition, the sliding fit between the chute and the guiding square shaft ensures the stable lifting of the pressure roller, reduces mechanical failures, and at the same time reduces cleaning dead corners. These designs significantly extend the service life of the equipment and comprehensively improve economic benefits. Brief Description of the Drawings

[0038] Example 1

[0039] Please refer to Figures 1 - 11 , a polyglutamic acid-based water-soluble fertilizer concentration processing device, including a reactor main body 1 and a feeding mechanism 2, and a mixing mechanism 3 is arranged in the reactor main body 1;

[0040] The reactor main body 1 includes a tank body 101, a second motor 102 and a drive shaft 103. The drive shaft 103 is fixedly installed on the output shaft of the second motor 102, and the second motor 102 is fixedly installed on the top of the tank body 101;

[0041] The feeding mechanism 2 includes a feeding hopper 201, a first motor 202, a screw rod 203 and a filter screen 204, and the feeding mechanism 2 is installed at the upper end of the reactor main body 1;

[0042] The mixing mechanism 3 includes a transmission shaft sleeve 301, a fixed shaft 302, a slide sleeve 303, a pressure roller 304, a dispersion paddle 305, a sealing sleeve 306 and a scraping paddle 307, and the mixing mechanism 3 is installed on the drive shaft 103.

[0043] Further, the pressure roller 304 is movably installed on the side end face of the transmission shaft sleeve 301. The top of the transmission shaft sleeve 301 is fixedly connected to the drive shaft 103. The side end face of the fixed shaft 302 is fixedly installed with a leg 30323 fixedly connected to the reactor main body 1. The fixed shaft 302 is inserted into the shaft sleeve and rotatably connected thereto. The upper end of the fixed shaft 302 is provided with a guiding square shaft 3021. The top of the guiding square shaft 3021 is provided with a positioning shaft 3022. A second gear umbrella 3045 is slidably connected to the guiding square shaft 3021. A sliding hole 30451 adapted to the guiding square shaft 3021 is provided at the center of the second gear umbrella 3045. A first gear umbrella 3044 meshing with the second gear umbrella 3045 is provided on the pressure roller 304. A connecting frame 3046 rotatably connecting the first gear umbrella 3044 and the second gear umbrella 3045 is provided inside the transmission shaft sleeve 301.

[0044] When the second motor 102 drives the drive shaft 103 to rotate, the drive shaft 103 drives the transmission shaft sleeve 301 to rotate, so that the pressure roller 304 rotates around the axis of the transmission shaft sleeve 301. Since the fixed shaft 302 is fixedly installed in the reactor main body 1, during the rotation of the transmission shaft sleeve 301, through the cooperation of the first gear umbrella 3044 and the second gear umbrella 3045, the pressure roller 304 rotates around its own axis, pressing the powder on the surface layer of the liquid material into the liquid material and improving the mixing effect.

[0045] Further, the sliding sleeve 303 is slidably installed on the outer end face of the transmission shaft sleeve 301 and slidably connected thereto. A sliding groove 3011 slidably cooperating with the pressure roller 304 is provided on the outer end face of the transmission shaft sleeve 301. A second shaft sleeve 3031 rotatably cooperating with the pressure roller 304 is provided at the middle of the side end face of the sliding sleeve 303. The length of the sliding sleeve 303 is more than twice the length of the sliding groove 3011.

[0046] The structure of the sliding groove 3011 enables the pressure roller 304 to slide up and down along the sliding groove 3011, and the guiding square shaft 3021 and the gear umbrella structure slidably connected thereto enable stable transmission during the sliding process. By covering the sliding groove 3011 with the sliding sleeve 303, it is avoided that the liquid material pours into the transmission shaft sleeve 301 during the up and down sliding of the pressure roller 304, which is not convenient for equipment flushing.

[0047] Further, the pressure roller 304 includes a rotating roller 3041 and an arc-shaped fan blade 3042. An ear plate 3043 is provided on the side end face of the arc-shaped fan blade 3042. The dispersing paddle 305 includes a rotating shaft 3051 and paddle blades 3052. The paddle blades 3052 are fixedly installed on the side of the rotating shaft 3051. The rotating shaft 3051 passes through the ear plate 3043 and is rotatably connected to the arc-shaped fan blade 3042.

[0048] During the rotation of the pressure roller 304, the arc-shaped fan blades 3042 press the powder raw materials floating on the surface of the liquid material into the water, and the dispersion paddle 305 stirs and mixes the raw material powder and the liquid material in the liquid material, thereby improving the uniformity of the mixing material, avoiding the continuous floating of the powder raw materials on the surface of the liquid material, and affecting the quality of the final waste product.

[0049] Further, a first gear 3032 is fixedly installed on the second bushing 3031, and a second gear 30511 meshing with the first gear 3032 is provided on the rotating shaft 3051.

[0050] When the pressure roller 304 rotates around the second bushing 3031, through the transmission of the first gear 3032 and the second gear 30511, the rotating shaft 3051 is driven to rotate at a high speed, so that the rotating shaft 3051 drives the paddle 3052 on its side to stir and disperse the raw materials and the liquid material, improving the mixing speed and uniformity of the raw materials.

[0051] Further, the sealing sleeve 306 is fixedly installed at the position of the sliding sleeve 303 close to the second bushing 3031. The sealing sleeve 306 includes a third sleeve 3061 and a turntable 3062 which are rotatably connected. An axial hole 30621 rotatably matched with the rotating shaft 3051 is provided on the turntable 3062, and the roller 3041 is of a hollow structure.

[0052] The first gear 3032 and the second gear 30511 are isolated from the liquid material through the sealing sleeve 306, avoiding the wear and corrosion of the gears caused by long-term immersion in the liquid material. The roller 3041 is of a hollow structure, so that the pressure roller 304 always floats on the upper end surface of the liquid material to mix the liquid material and the powder raw materials, thereby being able to adapt to the requirements of different production yields.

[0053] Further, the scraping paddle 307 includes a scraping plate 3071, a connecting plate 3072 and a fixing ring 3073. The fixing ring 3073 is fixedly installed at the bottom of the transmission shaft sleeve 301. The scraping plate 3071 is fixed to the fixing ring 3073 through a connecting rod, and the scraping plate 3071 is attached to the inner end surface of the tank body 101.

[0054] When the second motor 102 drives the transmission shaft sleeve 301 to rotate, the scraping plate 3071 shovels up the raw materials precipitated in the tank body 101, thereby improving the uniformity of the raw material mixing, avoiding the long-term precipitation and caking of the materials, and improving the quality of the final fertilizer product.

[0055] Further, the filter screen 204 is fixedly installed in the feeding hopper 201 through bolts. A feeding cylinder 2011 is provided on the side end surface of the feeding hopper 201. The auger rod 203 is installed in the feeding cylinder 2011 and is rotatably connected thereto. The first motor 202 is installed on the side end surface of the feeding cylinder 2011 to drive the auger rod 203, and a feeding port 2012 is provided on the lower end surface of the feeding cylinder 2011.

[0056] The caked materials in the raw materials are filtered and intercepted by the filter screen 204, and then the auger rod 203 is driven to rotate by the first motor 202, so that the auger rod 203 sends the raw materials to the feeding port 2012, and then falls into the main body of the mixing pipe through the feeding port 1014. Mechanical feeding saves labor and prevents large pieces of materials from entering the main body 1 of the reaction kettle, affecting the mixing speed.

[0057] Furthermore, a manhole 105 and a feeding port 1014 are arranged at the top of the tank body 101, a heat preservation jacket 1011 is arranged on the side wall of the tank body 101, and a water inlet 1012 and a return port 1013 are arranged on the side end face of the heat preservation jacket 1011.

[0058] A heat preservation jacket 1011 is arranged on the side wall of the fermentation tank. By continuously introducing warm water into the heat preservation jacket 1011, the dissolution of the raw materials is accelerated, and the mixing rate of the raw materials is further improved.

[0059] When this equipment is in use, the first motor 202 is started to drive the auger rod 203 to rotate, and the pretreated raw materials are conveyed to the feeding cylinder 2011 through the feeding hopper 201. After being filtered by the filter screen 204, the raw materials fall into the feeding port 1014 of the main body 1 of the reaction kettle from the feeding port 2012. A certain amount of water is added through the feeding port 1014 or the manhole 105 at the top of the tank body 101. The second motor 102 is started, and the driving shaft 103 drives the transmission shaft sleeve 301 to rotate. Then, the pressing roller 304 revolves around the axis of the transmission shaft sleeve 301. The pressing roller 304 realizes self-rotation through the meshing of the first tooth umbrella 3044 and the second tooth umbrella 3045. Its arc-shaped fan blade 3042 presses the floating powder raw materials into the liquid material. The sliding sleeve 303 slides up and down along the chute 3011 outside the transmission shaft sleeve 301 to adapt to different liquid levels. At the same time, the sealing sleeve 306 prevents the liquid material from entering the transmission components. When the pressing roller rotates, through the transmission of the first gear 3032 and the second gear 30511, the rotating shaft 3051 of the dispersing paddle 305 is driven to rotate at a high speed, strengthening the mixing of the liquid material and the powder. The scraping paddle 307 rotates with the transmission shaft sleeve 301 to scrape up the raw materials deposited at the bottom of the tank body 101 to prevent caking. Warm water at 50 - 60 °C is introduced into the heat preservation jacket 1011, injected through the water inlet 1012, and circulated through the return port 1013 to accelerate the dissolution of the raw materials and the uniformity of mixing.

[0060] Example 2

[0061] Please refer to Figures 1 - 11 , a method for concentrating and processing a polyglutamic acid-based water-soluble fertilizer, comprising the following steps:

[0062] Step 1: Conduct strict quality inspections on the raw materials such as polyglutamic acid and other nutrient elements nitrogen, phosphorus, potassium, trace elements, etc. Check whether the indexes such as purity, particle size, water content of the raw materials meet the production requirements, ensure the stable quality of the raw materials, accurately calculate the dosage of various raw materials according to the formula requirements of the target polyglutamic acid-based water-soluble fertilizer, and use high-precision weighing equipment to accurately weigh the raw materials to ensure the accurate ratio of each raw material.

[0063] Step 2: Start the first motor 202 to make the auger rod 203 start to rotate. Adjust the rotation speed of the first motor 202 to control the conveying speed of the raw materials, ensure that the raw materials can be evenly and stably conveyed to the feeding port 2012 through the feeding cylinder 2011. Slowly pour the pre-treated raw materials into the feeding hopper 201. When the raw materials pass through the filter screen 204, the agglomerated materials are intercepted, and the qualified raw materials are conveyed to the feeding port 2012 through the auger rod 203, and then fall into the mixing tank body through the feeding port 1014.

[0064] Step 3: Start the second motor 102. The drive shaft 103 drives the transmission shaft sleeve 301 to rotate. The rotation of the transmission shaft sleeve 301 makes the pressing roller 304 rotate around its own axis and rotate around the axis of the transmission shaft sleeve 301 at the same time, pressing the powder on the surface of the liquid material into the liquid material. At the same time, through the transmission of the first gear 3032 and the second gear 30511, drive the rotating shaft 3051 of the dispersion paddle 305 to rotate at a high speed, and the paddle blades 3052 stir and disperse the raw materials and the liquid material. Continuously introduce warm water at an appropriate temperature into the heat preservation jacket 1011. By adjusting the water temperature, water flow rate of the water inlet 1012 and the flow rate of the return port 1013, control the temperature in the tank body 101 within a suitable range to accelerate the dissolution of the raw materials and the chelation reaction. During the mixing process, use a pH meter to monitor the pH value of the liquid material in real time, and slowly add an appropriate amount of acid-base regulator, such as dilute hydrochloric acid or sodium hydroxide solution, to adjust the pH value of the liquid material according to the optimal pH conditions of the chelation reaction.

[0065] Step 4: Increase the heat medium temperature of the heat preservation jacket 1011. During the heating process, control the heating speed and temperature to avoid local overheating of the liquid material, resulting in loss of nutrients or charring.

[0066] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
