Description

Technical Field

[0001] This utility model relates to the field of fertilizer preparation technology, specifically to a fertilizer preparation reaction vessel. Background Technology

[0002] A reaction vessel is a key piece of equipment in the production of fertilizers, especially liquid fertilizers. It mixes powdered raw materials with other ingredients and liquids in the reaction vessel, producing a liquid compound fertilizer containing multiple nutrients. For example, Chinese Patent 201821101846.4 discloses a fully automatic metering reaction liquid fertilizer production equipment, comprising a body consisting of a first platform, a second platform, and a third platform arranged sequentially from bottom to top, and an elevator located on one side of the body. The third platform has several powder tanks and several liquid tanks. A screw conveyor is located below the outlet of the powder tanks, and a movable weighing tank is located below the screw conveyor to facilitate connection with the outlet of the screw conveyor. The second platform has a reaction vessel and a mixing vessel. The inlet of the reaction vessel is connected to the outlet of the weighing tank and the outlet of the liquid tank, respectively. The inlet of the reaction vessel is also connected to a pure water machine.

[0003] The existing technology has the following problems: Powder is generally directly fed into the powder inlet of the reactor and put into the reactor body. When the powder is directly fed into the reactor through the inlet, a large amount of powder comes into contact with the liquid in the reactor body, which will form a local high concentration area at the contact point. This makes the powder particles easy to attract each other and gather together, resulting in agglomeration, which affects the uniformity and quality of the final product. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose a fertilizer preparation reactor to solve the technical problem that powder materials are prone to agglomeration when directly added to the reactor and come into contact with the liquid in the prior art.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a fertilizer preparation reaction vessel, comprising:

[0007] The vessel body has a powder feeding port on it;

[0008] A uniform dispersion drive mechanism, installed inside the reactor body, has a movable end that reciprocates along a horizontal plane and corresponds to the powder feeding port; and

[0009] A powder dispersing hopper is disposed on the movable end of the dispersing drive mechanism and has a plurality of dispersing through holes, so that the powder dispersing hopper can reciprocate to disperse the powder and allow the dispersed powder to pass through the dispersing through holes for feeding.

[0010] In some embodiments, a plurality of the uniform dispersion through holes are arranged in an array on the inner bottom wall of the powder uniform dispersion hopper, and the uniform dispersion through holes are in the shape of an inverted cone.

[0011] In some embodiments, the cross-sectional shape of the powder dispersing hopper is trapezoidal.

[0012] In some embodiments, the uniform distribution drive mechanism includes a telescopic mechanism and a connecting frame. The telescopic mechanism is mounted on the vessel body and has a linearly telescopic movable end. The connecting frame is connected to the movable end of the telescopic mechanism.

[0013] In some embodiments, the powder dispersing hopper is inserted into the connecting frame.

[0014] In some embodiments, the bottom of the powder dispersing hopper is provided with a plurality of slots, and the top of the connecting frame is connected with a plurality of plug rods that are inserted into each of the slots.

[0015] In some embodiments, an insert groove is provided on the inner side of the powder feeding port, and an extension tube is inserted into the insert groove for extending to the top plane of the powder dispersing hopper.

[0016] In some embodiments, the vessel body includes a vessel body and a uniform dispersion bucket mounting cover. A mounting port is provided on one side of the vessel body. The uniform dispersion bucket mounting cover is inserted into the mounting port and is detachably connected to the vessel body by bolts and nuts. The uniform dispersion drive mechanism is mounted on the uniform dispersion bucket mounting cover.

[0017] In some embodiments, the uniform dispersion bucket mounting cover includes an end cap and an insert block. The insert block is fixedly connected to one side of the end cap and inserted into the mounting port. The surface of the insert block away from the end cap matches the curvature of the inner wall of the vessel body. The end cap is pressed against the end face of the mounting port.

[0018] In some embodiments, the reactor body includes an upper reactor body and a lower reactor body. The upper reactor body is detachably connected to the lower reactor body by bolts and nuts. A stirring mechanism is installed on the upper reactor body. The stirring mechanism has a rotatable agitator. The powder dispersing hopper is arranged between the agitator and the powder feeding port.

[0019] Compared with the prior art, the fertilizer preparation reactor provided by this utility model has a uniform dispersion driving mechanism and a powder uniform dispersion hopper set in the reactor body. After the powder is put into the powder feeding port, the uniform dispersion driving mechanism drives the powder uniform dispersion hopper to reciprocate and move laterally, shaking and dispersing the powder and letting it fall from each uniform dispersion through hole. This disperses the powder evenly and makes it contact the liquid in the reactor body, reducing agglomeration and improving the uniformity and quality of the final product.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] To address the technical problem that direct feeding of powdered materials into a reaction vessel can easily lead to agglomeration when the materials come into contact with the liquid, this invention provides a fertilizer preparation reaction vessel that can disperse the powdered materials and feed them evenly, thereby reducing the probability of agglomeration.

[0031] It should be noted that the fertilizer preparation reactor described in this utility model is used for, but not limited to, the preparation of liquid fertilizer. For ease of explanation, this utility model only uses the application of the fertilizer preparation reactor to the preparation of liquid fertilizer as an example. The principle of the fertilizer preparation reactor in other types of equipment is essentially the same as that in the preparation of liquid fertilizer, and will not be described in detail here.

[0032] Please see Figure 1 and Figure 2 , Figure 2 This is a three-dimensional exploded view of a fertilizer preparation reactor according to an embodiment of the present invention. The fertilizer preparation reactor includes a reactor body 1, a uniform dispersion driving mechanism 2, and a powder uniform dispersion hopper 3. The reactor body 1 has a powder feeding port 101 located at the top of the reactor body 1, allowing powder to be fed into the reactor body 1 from above. The top of the reactor body 1 also has multiple other inlets for connecting to different liquid raw material injection pipes to inject pure water or liquid raw materials, allowing the liquid and powder to mix within the reactor body 1. The uniform dispersion driving mechanism 2 is installed inside the reactor body 1 and has a movable end that reciprocates along the horizontal plane and corresponds to the powder feeding port 101, used to drive the powder uniform dispersion hopper 3 to reciprocate. The powder uniform dispersion hopper 3 is located within the uniform dispersion driving mechanism 2. The active end is provided with several uniform dispersion through holes 301, which allows the powder uniform dispersion hopper 3 to reciprocate and shake the powder, and the powder is dispersed and fed through the uniform dispersion through holes 301. The powder poured into the powder uniform dispersion hopper 3 is slowed down and shaken to make it evenly distributed on the powder uniform dispersion hopper 3. The powder is evenly distributed through the various uniform dispersion through holes 301. In addition, during the movement, the powder is not injected in a fixed position, and the injection area of ​​the powder is moved and expanded, which achieves the purpose of dispersing the powder and injecting it in a non-fixed position. This can effectively reduce the concentration of injected powder. With the powder being evenly distributed, possible agglomeration is avoided, the mixing effect between powder and liquid is improved, and the uniformity and quality of the product are improved.

[0033] In this embodiment, the uniform dispersion driving mechanism 2 can be linearly reciprocating, and the range of linear reciprocating driving is always directly below the powder feeding port 101, and the area of ​​the powder uniform dispersion hopper 3 is larger than the diameter of the powder feeding port 101. Alternatively, the uniform dispersion driving mechanism 2 can also be a vibrating motor, driving the powder uniform dispersion hopper 3 to form a shaking action, which can also shake and disperse the powder.

[0034] In one embodiment, please refer to Figure 4 and Figure 5 To guide powder dispersion and reduce powder retention, multiple dispersion through-holes 301 are arranged in an array on the inner bottom wall of the powder dispersion hopper 3. The array arrangement is based on the shape of the powder dispersion hopper 3, filling the entire inner bottom wall of the powder dispersion hopper 3. The dispersion through-holes 301 are inverted cone shapes, with the larger base facing upwards and the smaller base facing downwards, which reduces the amount discharged after guiding powder dispersion. Furthermore, the larger bases of adjacent dispersion through-holes 301 are tangent, and a rounded corner is provided at the midpoint between multiple tangent dispersion through-holes 301, extending into each dispersion through-hole 301, reducing the possible planar area of ​​the bottom surface. The arc and slope guide the powder into each dispersion through-hole 301, reducing powder retention.

[0035] In this embodiment, the powder is fed downwards and falls evenly into the powder distribution hopper 3. The powder is guided and evenly distributed through the various distribution holes 301, and then falls downwards to the liquid surface inside the vessel body 1 for subsequent mixing.

[0036] It is understandable that the uniform dispersion through-hole 301 can also achieve the effect of dispersing powder by being round, and the conical uniform dispersion through-hole 301 is only one of the preferred embodiments.

[0037] In one embodiment, please refer to Figure 4 In order to ensure the volume of the powder distribution hopper 3, the cross-sectional shape of the powder distribution hopper 3 is trapezoidal, that is, the internal volume of the powder distribution hopper 3 is outwardly expanded, which increases the volume of powder that can be piled up on it while keeping the bottom area constant.

[0038] It is understandable that the powder dispersing hopper 3 can also be a conical hopper, and this is not the only limitation.

[0039] In one embodiment, please refer to Figure 2 In order to drive the basic reciprocating movement of the powder dispersing hopper 3, the dispersing drive mechanism 2 includes a telescopic mechanism 21 and a connecting frame 22. The telescopic mechanism 21 is installed on the vessel body 1 and has a linearly telescopic movable end. The connecting frame 22 is connected to the movable end of the telescopic mechanism 21. By driving the connecting frame 22 to reciprocate linearly through the telescopic mechanism 21, the purpose of reciprocating movement along the horizontal plane can be achieved.

[0040] Among them, the area covered by the reciprocating movement of the powder dispersing hopper 3 always covers the feeding area of ​​the powder feeding port 101.

[0041] Understandably, the telescopic mechanism 21 can be an existing mature device with linear reciprocating drive function, such as a hydraulic push rod, an electric push rod, or a pneumatic push rod.

[0042] Furthermore, in order to facilitate the replacement and cleaning of the powder dispersing hopper 3, the powder dispersing hopper 3 is inserted into the connecting frame 22, which facilitates disassembly from the connecting frame 22.

[0043] Furthermore, in order to enhance the positioning effect after insertion, the bottom of the powder dispersing hopper 3 is provided with several insertion ports 302, and the top of the connecting frame 22 is connected with several insertion rods 2201 that are inserted into the insertion ports 302 one by one. The insertion of the insertion ports 302 and the insertion rods 2201 forms a positioning and improves the stability of insertion.

[0044] There are four inlets 302 and four inserts 2201. The inlets 302 are evenly distributed around the outer periphery of the powder dispersing hopper 3. The connecting frame 22 is square in shape, and the inserts 2201 are distributed at the four corners of the connecting frame 22.

[0045] Understandably, the insertion port 302 can be a through-hole that penetrates the powder distribution hopper 3, or it can be a non-penetrating slot, as long as it allows the insertion rod 2201 to be inserted.

[0046] In one embodiment, please refer to Figure 2 and Figure 3 In order to shorten the distance between the powder feeding port 101 and the powder dispersing hopper 3 when the distance is large, and reduce the instability of feeding, the powder feeding port 101 is provided with an inserting groove 102. An extension tube 103 is inserted into the inserting groove 102 to extend to the top plane of the powder dispersing hopper 3, thereby shortening the distance between the powder feeding port 101 and the powder dispersing hopper 3, so that the powder can be stably fed onto the powder dispersing hopper 3.

[0047] In one embodiment, please refer to Figure 1 and Figure 2 To facilitate the removal of the uniform dispersion drive mechanism 2 and the powder uniform dispersion hopper 3 from the vessel body 1, the vessel body 1 includes a vessel body 11 and a uniform dispersion hopper mounting cover 12. A mounting opening 1101 is provided on one side of the vessel body 11. The diameter of the mounting opening 1101 is larger than the maximum size of the uniform dispersion drive mechanism 2 or the powder uniform dispersion hopper 3, allowing the uniform dispersion drive mechanism 2 and the powder uniform dispersion hopper 3 to enter and exit. The uniform dispersion hopper mounting cover 12 is inserted into the mounting opening 1101 and is detachably connected to the vessel body 11 by bolts and nuts, used to close the mounting opening 1101. The uniform dispersion drive mechanism 2 is mounted on the uniform dispersion hopper mounting cover 12, so that after removing the uniform dispersion hopper mounting cover 12, the uniform dispersion drive mechanism 2 and the powder uniform dispersion hopper 3 can be removed from the mounting opening 1101 together.

[0048] Furthermore, in order to maintain the integrity of the inner wall of the vessel body 1, the uniform dispersion bucket mounting cover 12 includes an end cover 121 and an insert block 122. The insert block 122 is fixedly connected to one side of the end cover 121 and is inserted into the mounting port 1101. The side surface of the insert block 122 away from the end cover 121 matches the curvature of the inner wall of the vessel body 11, so that after the cover is closed, the inner wall of the vessel body 1 is integrated, and the end cover 121 is pressed against the end face of the mounting port 1101.

[0049] Furthermore, to avoid additional openings, a cavity can be provided within the insert block 122 to supply power and control the telescopic mechanism 21. A battery and control unit are installed within this cavity. The battery supplies power to the control unit and the telescopic mechanism. The control unit is a controller corresponding to the type of telescopic mechanism 21, and it is also equipped with a wireless module electrically connected to the controller for wireless control. All the above control equipment and methods utilize existing mature technologies.

[0050] In one embodiment, please refer to Figure 2 and Figure 3 To maintain the original stirring and avoid interference with the feeding, the main body 11 of the vessel includes an upper vessel 111 and a lower vessel 112. The upper vessel 111 is detachably connected to the lower vessel 112 by bolts and nuts. A stirring mechanism 113 is installed on the upper vessel 111. The stirring mechanism 113 has a rotatable agitator 114. The powder dispersing hopper 3 is arranged between the agitator 114 and the powder feeding port 101. The powder dispersing hopper 3 is arranged above the agitator 114 and moves back and forth in a direction away from the central axis of the agitator 114, thereby avoiding interference with the rotation of the agitator 114.

[0051] The stirring mechanism 113 can be driven by a drive motor to drive the agitator 114 to rotate.

[0052] Understandably, the liquid level is above the agitator 114 and below the powder dispersing hopper 3.

[0053] To better understand this utility model, the following is combined with... Figures 1 to 5 The technical solution of this utility model is described in detail as follows: Powder is fed into the vessel body 1 through the powder feeding port 101. Guided by the extension tube 103 of the powder feeding port 101, the powder is guided onto the powder dispersing hopper 3. Under the reciprocating extension and retraction of the telescopic mechanism 21 on the dispersing drive mechanism 2, the powder is shaken and dispersed into each dispersing through-hole 301. Guided by the conical dispersing through-hole 301, the powder is evenly distributed downwards and injected into the liquid surface of the vessel body 1. During the reciprocating movement, powder accumulation is avoided. The liquid is in contact with the liquid surface at one position, expanding the injection range. The stirring mechanism 113 inside the vessel 1 drives the agitator 114 to rotate, effectively mixing the liquid and powder. That is, pure water and liquid raw materials are first injected into the vessel 1, followed by powder. At the same time, the stirring mechanism 113 is started to drive the agitator 114 to rotate, forming a stirring of the liquid in the vessel 1 and dispersing the powder that has been injected into the liquid. After stirring and mixing and reaching the reaction time, the discharge valve at the bottom of the vessel 1 is opened to discharge the material.

[0054] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
