Description

Technical Field

[0001] This invention relates to the field of liquid fertilizer production technology, and in particular to an amino acid liquid fertilizer mixing vessel that can uniformly add materials. Background Technology

[0002] Amino acid liquid fertilizer is a water-soluble fertilizer made primarily of compound amino acid liquid, with the addition of various macro-elements, micro-elements, organic matter, humic acid, and various functional additives. It can provide plants with various small-molecule organic nitrogen, phosphorus, potassium, and other nutrients, improve soil structure and fertility, and thus promote vigorous plant growth.

[0003] The components in amino acid liquid fertilizers are relatively complex and vary considerably in properties. For example, the high concentrations of humic acid and fulvic acid extracts required in the components have high viscosity and poor fluidity. If they are not evenly dispersed during addition, they can easily coat solid particles or other droplets, preventing them from contacting the main solution and thus producing colloids or clumps.

[0004] For example, for some trace element salts with poor solubility, such as copper sulfate and boric acid, if the materials accumulate together during the addition process, they may not be completely dissolved within the specified mixing time. As a result, they may continue to dissolve or precipitate during subsequent storage or use, causing instability of the components and affecting the effectiveness of use.

[0005] To solve the above problems, the best approach is to evenly disperse the materials during the addition process, rather than simply dumping everything into the reactor all at once. Existing production equipment, such as the reaction vessel for amino acid fertilizer production disclosed in patent CN216654541U and the stirred tank for producing amino acid water-soluble fertilizer disclosed in patent CN222034524U, only possess basic stirring functions and do not optimize the material addition process. Consequently, the materials are not evenly dispersed, and the aforementioned problems persist.

[0006] In conclusion, the existing formulation process for amino acid liquid fertilizer still needs improvement, especially the method of adding materials. Summary of the Invention

[0010] Furthermore, a telescopic rod is provided on each of the two sides inside the housing. The upper end of the sleeve of the telescopic rod is rotatably connected to the inner wall of the housing through a rotating support. The lower end of the telescopic rod is rotatably connected to both ends of the third transmission shaft through a rotating sleeve. A spring is sleeved on the outer side of the telescopic rod. The two ends of the spring are fixedly connected to the bottom of the sleeve and the outer wall of the rotating sleeve, respectively.

[0011] Furthermore, the spiral track includes a horizontal plate, on which two protruding guide rails are symmetrically arranged on the upper and lower sides. Two traveling wheels are sleeved on the third drive shaft, and the two traveling wheels are respectively tumblingly connected to the guide rails on both sides.

[0012] Furthermore, each side of the horizontal plate is provided with a limiting groove along its spiral direction, and each of the rotating sleeves on both sides is provided with a connecting rod at its bottom. The end of the connecting rod is provided with a roller, and the roller is rolled within the limiting groove.

[0013] Furthermore, a through groove is provided in the middle of the horizontal plate along its spiral direction, and the end of the feeding pipe is slidably connected to the through groove through a feeding head.

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0023] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0024] In the description of the embodiments, unless otherwise explicitly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Example 1: like Figure 1-3 As shown, the amino acid liquid fertilizer mixing vessel in this embodiment, which can uniformly add materials, includes a vessel body 10, a cover 20, a stirring motor 30, a stirrer 40, a spiral track 50, and a walking feeding mechanism 60; the cover 20 is detachably installed at the top opening of the vessel body 10, specifically, the two can be connected by a snap-fit ​​or threaded method.

[0026] The top of the lid 20 is provided with a feeding port 21 for adding amino acid base liquid and other conventional materials into the vessel body 10; the bottom of the vessel body 10 is provided with a discharge port 11 for discharging the mixed materials from the vessel body 10; the bottom of the vessel body 10 is evenly distributed with multiple support legs 12, and each support leg 12 is provided with a self-locking universal wheel 13 at the bottom, which facilitates the movement and fixing of the mixing vessel at any time.

[0027] A heating jacket 70 is also provided on the outside of the vessel body 10, forming a heating chamber 80 between the heating jacket 70 and the vessel body 10. Multiple electric heating tubes 90 are provided at the bottom of the heating chamber 80. A water inlet 71 is provided on the upper side of the heating jacket 70, and a drain outlet 72 is provided on the lower side. Water is added into the heating chamber 80 through the water inlet 71, and heated by the electric heating tubes 90 to meet the reaction temperature requirements of some materials.

[0028] The stirring motor 30 is axially mounted on the top of the cover 20, and the stirrer 40 is axially mounted inside the vessel 10 and is connected to the stirring motor 30 for transmission. Specifically, the upper end of the stirrer 40 is provided with a connecting sleeve 41, the main shaft of the stirring motor 30 is inserted into the connecting sleeve 41, and is locked by a key block and a pin.

[0029] The spiral track 50 is radially arranged inside the vessel body 10 and near its top opening via multiple support arms 51. The upper end of the stirrer 40 passes through the center of the spiral track 50. Specifically, the two ends of the support arms 51 can be connected to the inner wall of the vessel body 10 and the spiral track 50 by bolts or welding, and it is ensured that the connection points will not affect the normal movement of the walking feeding mechanism 60.

[0030] The walking feeding mechanism 60 is set on the spiral track 50 and can travel cyclically along the upper and lower surfaces of the spiral track 50. The walking feeding mechanism 60 is connected to the feeding pipe 100. The other end of the feeding pipe 100 extends to the outside of the vessel body 10 through the cover 20. Various materials with high viscosity or poor solubility can be added into the vessel body 10 through the feeding pipe 100.

[0031] like Figure 4-6 As shown, the walking and feeding mechanism 60 includes a housing 61, a walking motor 62, a walking wheel 63, a counterweight wheel 64, and a transmission assembly. The walking motor 62 is movably mounted inside the housing 61 via a bracket 65. The walking wheel 63 is movably mounted at the bottom of the housing 61 via a telescopic rod 66. The counterweight wheel 64 is rotatably mounted at the rear bottom of the housing 61. The walking motor 62 is connected to the walking wheel 63 via the transmission assembly.

[0032] The counterweight wheel 64 can be made of high-density metal material or thickened and weighted to balance the center of gravity of the walking feeding mechanism 60. The wheel axle of the counterweight wheel 64 is a damped wheel axle, and the counterweight wheel 64 will only rotate when driven by the walking wheel 63, to prevent unnecessary movement of the walking feeding mechanism 60 due to inertia, thereby ensuring that the walking feeding mechanism 60 can always circulate along the upper and lower surfaces of the spiral track 50.

[0033] The transmission assembly includes a first bevel gear 67, a second bevel gear 68, a first spur gear 69, a second spur gear 610, a third spur gear 611, a first drive shaft 612, a second drive shaft 613, and a third drive shaft 614. The first bevel gear 67 is fixedly connected to the main shaft of the walking motor 62. The second bevel gear 68 is sleeved on the first drive shaft 612. A first spur gear 69 is provided at each end of the first drive shaft 612. The second drive shaft 613 is arranged parallel to the lower side of the first drive shaft 612 and has a second spur gear 610 at each end. The third drive shaft 614 is arranged parallel to the lower side of the second drive shaft 613 and has a third spur gear 611 at each end. The first spur gears 69, second spur gears 610, and third spur gears 611 on both sides mesh sequentially. The two side walls of the bracket 65 are respectively provided with a longitudinal sliding groove 651 and an arc-shaped sliding groove 652. The two ends of the first drive shaft 612 are slidably connected to the longitudinal sliding groove 651, and the two ends of the second drive shaft 613 are slidably connected to the arc-shaped sliding groove 652.

[0034] A telescopic rod 66 is provided on each side inside the housing 61. The upper end of the sleeve of the telescopic rod 66 is rotatably connected to the inner wall of the housing 61 through a rotating support 615, and the lower end of the rod body of the telescopic rod 66 is rotatably connected to both ends of the third transmission shaft 614 through a rotating sleeve 616.

[0035] A spring 617 is sleeved on the outer side of the telescopic rod 66, with both ends of the spring 617 fixedly connected to the bottom of the sleeve and the outer wall of the rotating sleeve 616, respectively. When the traveling wheel 63 travels on the upper surface of the spiral track 50, the spring 617 is in a compressed state; when the traveling wheel 63 travels on the lower surface of the spiral track 50, the spring 617 is in a stretched state; when the spring 617 is in a normal state (neither compressed nor stretched), the telescopic rod 66 is stretched to an appropriate length, so that the axis of the traveling wheel 63 exceeds the horizontal center plane of the spiral track 50.

[0036] When the traveling wheel 63 rotates to the end of the spiral track 50, the spring 617 is completely unloaded, and under the damping action of the counterweight wheel 64, and under the action of gravity and rotation, the traveling wheel 63 continues to roll along the arc surface at the end of the spiral track 50 until the traveling wheel 63 rolls completely to the lower surface of the spiral track 50; at this time, the spring 617 is stretched, which has a lifting effect on the traveling wheel 63, ensuring that it is always in contact with the lower surface of the spiral track 50 and continues to roll along its lower surface.

[0037] The spiral track 50 includes a horizontal plate 52, with two protruding guide rails 53 symmetrically arranged on the upper and lower sides of the horizontal plate 52. Two traveling wheels 63 are sleeved on the third drive shaft 614, and the two traveling wheels 63 are respectively rolledly connected to the guide rails 53 on both sides.

[0038] A through groove 54 is provided in the middle of the horizontal plate 52 along its spiral direction. The end of the feeding pipe 100 is slidably connected to the through groove 54 through the feeding head 110. This allows the feeding pipe 100 and the feeding head 110 to circulate around the spiral track 50, thereby achieving uniform feeding.

[0039] The feeding tube 100 is set long enough, and only the traveling wheel 63 circulates along the upper and lower surfaces of the spiral track 50, while the housing 61 and other structures always reciprocate on the upper surface of the spiral track 50, so the feeding tube 100 will not get tangled on the agitator 40.

[0040] Example 2: like Figure 7-9 As shown, in another embodiment, a limiting groove 55 is provided on each side of the horizontal plate 52 along its spiral direction, and a connecting rod 56 is provided at the bottom of each rotating sleeve 616 on both sides. The end of the connecting rod 56 is provided with a roller 57, which is rolled in the limiting groove 55. The outer diameter of the traveling wheel 63 is equal to the center distance between the end of the limiting groove 55 and the traveling wheel 63.

[0041] When the traveling wheel 63 moves to the end of the spiral track 50, with the assistance of the connecting rod 56, the traveling wheel 63 can always be in contact with the spiral track 50, thereby ensuring that the traveling wheel 63 rolls to the lower surface of the spiral track 50 and continues to travel along the lower surface.

[0042] When the traveling wheel 63 moves to the other end of the spiral track 50, the above action is repeated, thereby realizing the traveling feeding mechanism 60 to circulate on the spiral track 50 without changing the direction of the traveling motor 62.

[0043] In addition, to increase the friction between the traveling wheel 63 and the spiral track 50, they can be made of materials with high surface friction such as rubber or nylon; or they can be made of metal materials such as aluminum alloy or stainless steel, and their surfaces can be roughened to increase friction texture; or their surfaces can be machined into a structure similar to gears and racks to achieve meshing transmission between them.

[0044] In summary, the present invention, through the cooperation of the spiral track 50 and the walking feeding mechanism 60, can uniformly add materials into the inside of the reactor body 10, increase the contact area between the materials and the liquid inside the reactor body 10, facilitate their rapid dispersion, and further, through the stirring motor 30 driving the stirrer 40 to stir and mix the materials, can avoid the problems of colloids, agglomeration or precipitation caused by differences in the viscosity or solubility of the materials, thereby improving the mixing effect of the materials and ensuring the product quality of amino acid liquid fertilizer.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by the present invention.
