A foliar fertilizer homogenizer

Abstract

This invention provides a foliar fertilizer homogenizer, comprising a shell, a column, a main shaft, a feed diversion assembly, a guide shear seat, a coarse shear diversion hood, a fine shear guide seat, and a fine homogenization mechanism. The guide shear seat comprises a three-section structure: a coarse shearing section, a pushing section, and a fine shearing collection section, which respectively cooperate with the conical groove, the coarse shear diversion hood, and the fine shear guide seat to form a three-stage shearing system. The feed diversion assembly separates coarse and fine materials during the feeding stage; fine materials directly enter the fine shear guide seat, while coarse materials undergo coarse and fine shearing sequentially. The uniformly oriented collection hood enables active material collection, and the high-speed material in the second channel generates a siphon effect against the fixed shear orifice, accelerating discharge. This invention achieves highly efficient homogenization of foliar fertilizer through the synergistic effect of graded feeding, multi-stage shearing, and siphon discharge, offering advantages such as good homogenization effect and low energy consumption.

Description

Technical Field

[0001] This invention relates to the field of fertilizer production equipment technology, and in particular to a foliar fertilizer homogenizer. Background Technology

[0002] Foliar fertilizer is a type of fertilizer that applies nutrients directly to the leaves of plants. It is an important supplementary way for plants to absorb nutrients and can effectively compensate for insufficient nutrient absorption by the root system. Homogenizing foliar fertilizer using a homogenizing device promotes foliar absorption and improves fertilizer utilization efficiency. With the increasing demands for fertilizer quality in modern agriculture, the performance of foliar fertilizer homogenizing equipment directly affects product quality and production efficiency.

[0003] Homogenizers are core equipment in foliar fertilizer production for dispersing, mixing, and refining materials. Existing homogenizing equipment primarily uses the relative motion between a high-speed rotating rotor and stator to apply shearing, impact, and cavitation effects to the material, thereby achieving material refinement and homogenization. In the field of high-shear homogenizers, existing equipment uses a special crushing device on the rotor to allow material to directly enter the high-shear crushing zone from the inlet. Within the narrow working channel, the rotor blades and stator blades cut at high speed, generating intense friction and grinding. However, existing technologies still have the following technical problems when applied to foliar fertilizer homogenization: First, existing homogenizers typically use a uniform processing path, making it difficult to classify materials according to particle size differences. This leads to a situation where excessive shearing of fine materials and insufficient shearing of coarse materials coexist, affecting homogenization efficiency and energy utilization. Second, fine particles tend to remain in the shearing zone after shearing. If the refined material cannot be discharged from the shearing zone in time during high-speed operation of the homogenizer, it will repeatedly undergo unnecessary shearing, resulting in energy waste and increased material temperature, affecting the stability of heat-sensitive components in the foliar fertilizer. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a foliar fertilizer homogenizer that can achieve integrated processing of graded feeding, multi-stage shearing, and fine homogenization of foliar fertilizers, thereby improving homogenization efficiency and product fineness uniformity while reducing energy consumption.

[0005] According to an embodiment of the present invention, a foliar fertilizer homogenizer is provided, comprising a housing, a column coaxially fixed to the top of the housing, and a main shaft coaxially penetrating the column and extending into the housing. The column extends into the housing and has multiple sets of feed diversion components inside. A guide shearing seat located below the column is coaxially connected to the main shaft. The guide shearing seat includes an upper frustum-shaped coarse shearing section, a middle cylindrical pushing section, and a lower inverted frustum-shaped fine shearing section. A bottom side of the column is detachably connected to the guide shearing section. The coarse shearing section and the coarse shearing diverter corresponding to the pushing section are provided. A fine shearing guide seat with an annular structure located below the coarse shearing diverter is fixedly connected to the inner wall of the housing. The fine shearing guide seat is provided with a first channel for receiving the fine material diverted by the feeding diverter assembly and a second channel for receiving the coarse shearing diverter. The fine shearing guide seat cooperates with the collecting fine shearing section to shear and disperse the coarse material into fine material. A fine dispersion mechanism is also provided between the housing and the main shaft, located below the fine shearing guide seat, for dispersing all the fine material uniformly.

[0006] Preferably, the top of the material guiding coarse shearing section is provided with radial shearing ribs, and a material guiding channel is formed between adjacent shearing ribs. The bottom end of the column is provided with a conical groove that matches the material guiding coarse shearing section, and the shearing ribs extend into the conical groove and are fitted with it with a gap.

[0007] More preferably, the coarse shearing diversion hood includes an inverted conical portion at the top and a cylindrical diversion portion at the bottom. The inner side of the cylindrical diversion portion is coaxially provided with a diversion screen cylinder fixedly connected to the inverted conical portion. The inner wall of the inverted conical portion is fixedly provided with coarse shearing teeth corresponding to the shearing ribs. The cylindrical diversion portion is fixedly connected to the fine shearing diversion seat and corresponds to the second channel, guiding the high-speed flowing material into the second channel.

[0008] More preferably, the pushing part is located inside the diversion screen cylinder, and its side is provided with spiral pushing ribs. The coarse shearing teeth extend to the bottom of the diversion screen cylinder, and can form a certain shearing effect with the rotating pushing part.

[0009] More preferably, the fine shearing section includes a collection chamber disposed therein, a plurality of collection covers fixed thereon, and a movable shearing hole extending from the inside of the collection chamber to the outer side of the fine shearing section. The plurality of collection covers have openings that face the same clockwise or counterclockwise direction and communicate with the collection chamber, thereby gathering materials into the collection chamber when rotating with the guide shearing seat.

[0010] More preferably, the inner sidewall of the fine shearing drainage seat is provided with a fixed shearing hole corresponding to the moving shearing hole.

[0011] More preferably, the fixed shearing hole is connected to the second channel, and the high-speed material in the second channel can generate a siphon effect on the material in the fixed shearing hole, accelerating the passage of the finely sheared material through the fixed shearing hole.

[0012] More preferably, the moving shear hole and the fixed shear hole are perpendicular to the side of the fine shear section of the aggregate, and the second channel is parallel to the side of the fine shear section of the aggregate.

[0013] More preferably, the feeding diversion assembly includes multiple feeding channels parallel to the main shaft and extending downward through the column, a feeding auger coaxially disposed in the feeding channel, a fine material separating screen hole disposed on the side of the feeding channel and located in the housing, a feeding hole provided on the top side of the feeding channel, and a synchronous rotation assembly provided between the multiple feeding augers and the main shaft.

[0014] In a further preferred embodiment, the rotating shaft of the feeding auger passes upward through the column, and the synchronous rotation assembly includes a driven gear connected to the top end of the rotating shaft of the feeding auger, a driving gear coaxially connected to the main shaft and meshing with the multiple driven gears, and a feeding hopper located outside the feeding hole is coaxially fixedly connected to the outer side of the column.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Through the coordinated operation of the feed diversion assembly, the three-section structure of the guide shear seat, the coarse shear diversion hood, and the fine shear guide seat, coarse and fine material diversion processing is achieved from the feeding stage. Fine material enters the first channel directly through the fine material distribution hole, bypassing the coarse shearing stage; coarse material undergoes coarse and fine shearing processes sequentially. This graded processing method matches the workload of each processing unit with the particle size of the material it processes, effectively avoiding excessive shearing of fine material and insufficient shearing of coarse material, significantly improving homogenization efficiency and equipment utilization.

[0017] The material guiding shearing unit integrates three different functions—coarse shearing, pushing, and fine shearing—on a single rotating component, corresponding to the three stages of material coarse shearing and dispersion, forced guiding and propulsion, and fine shearing. These three functional sections, along with their corresponding fixed components (conical groove, coarse shearing diverter, and fine shearing guide), form shearing pairs, creating a progressive shearing system from coarse to fine. The material can undergo the complete three-stage shearing process within a single device.

[0018] The uniform orientation of the material collection hoods allows the rotating guide shear seat to actively collect surrounding material into the collection chamber, significantly improving the material supply efficiency in the fine shearing zone. Simultaneously, the siphon effect generated by the high-speed material in the second channel on the material in the fixed shearing orifice accelerates the discharge of sheared material, effectively preventing repeated shearing and retention.

[0030] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] This invention provides an embodiment, such as... Figure 1 , Figure 2 As shown, a foliar fertilizer homogenizer includes a housing 1, a column 2 coaxially fixed to the top of the housing 1, and a main shaft 3 coaxially passing through the column 2 and extending into the interior of the housing 1. The upper end of the main shaft 3 is connected to an external drive motor, which provides rotational power.

[0032] The column 2 extends into the interior of the housing 1, and multiple sets of feed diversion components 210 are provided inside it. A guide shear seat 4 located below the column 2 is coaxially connected to the main shaft 3. The guide shear seat 4 rotates synchronously with the main shaft 3. The guide shear seat 4 includes an upper frustum-shaped coarse shearing part 410, a middle cylindrical push part 420, and a lower inverted frustum-shaped fine shearing part 430.

[0033] The bottom side of the column 2 is detachably connected by bolts to a coarse shearing diverter 5 corresponding to the material guiding coarse shearing part 410 and the material pushing part 420. A fine shearing guide seat 6 with an annular structure located below the coarse shearing diverter 5 is fixedly connected to the inner wall of the housing 1. The fine shearing guide seat 6 is provided with a first channel 610 for receiving the fine material diverted by the feeding diverter assembly 210 and a second channel 620 for receiving the coarse shearing diverter 5. The fine shearing guide seat 6 cooperates with the material collecting fine shearing part 430 to shear and disperse the coarse material into fine material.

[0034] A fine dispersion mechanism 7 is also provided between the housing 1 and the main shaft 3, located below the fine shearing guide seat 6, for dispersing and homogenizing all fine materials, and for performing final dispersion and homogenization treatment on all fine materials that have undergone pre-processing.

[0035] Specifically, the feed diversion assembly 210 includes multiple feed channels 211 parallel to the main shaft 3 and penetrating downward through the column 2, feed augers 212 coaxially arranged in the feed channels 211, and fine material separating screen holes 213 arranged on the side of the feed channels 211 and located in the housing 1. The top side of the feed channels 211 is provided with feed holes 214, and a synchronous rotation assembly 220 is provided between the multiple feed augers 212 and the main shaft 3.

[0036] The rotating shaft of the feeding auger 212 passes through the column 2 upwards. The synchronous rotation assembly 220 includes a driven gear 221 connected to the top of the rotating shaft of the feeding auger 212, and a driving gear 222 coaxially connected to the main shaft 3 and meshing with the multiple driven gears 221. The outer side of the column 2 is coaxially fixedly connected to a feeding hopper 215 located outside the feeding hole 214.

[0037] The foliar fertilizer material to be processed is fed into the feed hopper 215. The material enters each feed channel 211 through the feed hole 214. When the feed auger 212 rotates, it applies a downward pushing force to the material to prevent the material from being blocked in the channel. At the same time, it initially disperses the material. As the material moves downward in the feed channel 211, the finer particles with smaller particle sizes are diverted through the distribution screen hole 213 and fall directly into the first channel 610 of the fine shearing guide seat 6, bypassing the subsequent coarse shearing stage. The remaining material continues to flow downward along the feed channel 211 and reaches the bottom of the column 2. After the material is discharged from the bottom of the feed channel 211, it enters the top area of ​​the coarse shearing section 410.

[0038] Specifically, such as Figure 1 , Figure 3 As shown, the top of the material guiding coarse shearing section 410 is provided with radial shearing ribs 411, and a material guiding channel 412 is formed between adjacent shearing ribs 411. The bottom end of the column 2 is provided with a conical groove 201 that matches the material guiding coarse shearing section 410, and the shearing ribs 411 extend into the conical groove 201 and are fitted with it with a gap.

[0039] The coarse shearing section 410 rotates at high speed with the main shaft 3. The radial shearing ribs 411 at the top of the section and the conical groove 201 at the bottom of the column 2 move relative to each other, producing a preliminary shearing and dispersing effect on the material.

[0040] To facilitate the separation of materials generated by centrifugation and guide the high-speed flowing fines generated after shearing to the second channel 620, in a further embodiment, such as Figure 1 , Figure 4 As shown, the coarse shearing diversion hood 5 includes an inverted conical portion 510 located at the top and a cylindrical guide portion 520 located at the bottom. The inner side of the cylindrical guide portion 520 is coaxially provided with a diversion screen cylinder 530 fixedly connected to the inverted conical portion 510. The inner wall of the inverted conical portion 510 is fixedly provided with coarse shearing teeth 511 corresponding to the shearing ribs 411. The cylindrical guide portion 520 is fixedly connected to the fine shearing guide seat 6 and corresponds to the second channel 620, guiding the high-speed flowing material into the second channel 620.

[0041] Under centrifugal force, the material moves to the inner side of the inverted cone 510. The shearing ribs 411 rotating with the main shaft 3 and the coarse shearing teeth 511 fixed on the inner wall of the inverted cone 510 form a high-speed relative motion, applying a strong shearing action to the material and breaking large particle agglomerates into smaller particles. The material after coarse shearing enters the diversion screen cylinder 530 area;

[0042] To accelerate the downward movement of the material, in a further embodiment, such as Figure 4As shown, the pushing part 420 is located inside the diversion screen cylinder 530, and its side is provided with spiral pushing ribs 421. The coarse shearing teeth 511 extend to the bottom of the diversion screen cylinder 530 and can form a certain shearing effect with the rotating pushing part 420.

[0043] The spiral pushing ribs 421 on the side of the pushing part 420 rotate with the main shaft 3, applying a downward pushing force to the material, forcing the material to move downward along the inner wall of the diversion screen cylinder 530. Material with a particle size smaller than the screen hole size of the diversion screen cylinder 530 can pass through the screen cylinder and enter the cylindrical guide part 520, and then be conveyed to the second channel 620 of the fine shearing guide seat 6; material with a larger particle size is blocked by the diversion screen cylinder 530 and subjected to the shearing effect of the coarse shearing teeth 511.

[0044] To provide diverse shearing effects, in a further embodiment, the fine shearing section 430 includes a collection chamber 431 disposed therein, a plurality of collection covers 432 fixed thereon, and a movable shearing hole 433 extending from the inside of the collection chamber 431 to the outer side of the fine shearing section 430. The plurality of collection covers 432 have openings facing the same clockwise or counterclockwise direction and communicate with the collection chamber 431, and gather materials into the collection chamber 431 when rotating with the guide shearing seat 4.

[0045] After coarse shearing, the material moves downwards. When the fine shearing section 430 rotates at high speed, it is actively collected by the collecting hood 432 on its surface and guided into the collecting chamber 431. Since the openings of multiple collecting hoods 432 are all facing the same direction, the collecting hoods 432 form a collecting effect similar to an impeller when rotating, which effectively increases the material feeding efficiency.

[0046] To improve the fine shearing effect, in a further embodiment, the inner sidewall of the fine shearing drainage seat 6 is provided with a fixed shearing hole 601 corresponding to the moving shearing hole 433.

[0047] After entering the collection chamber 431, the material is discharged outward through the dynamic shear hole 433 under the combined action of centrifugal force and the internal pressure of the collection chamber 431. During the rotation of the guide shear seat 4, the dynamic shear hole 433 and the fixed shear hole 601 on the inner wall of the fine shear guide seat 6 periodically align and misalign. When the dynamic shear hole 433 aligns with the fixed shear hole 601, the material under pressure in the collection chamber 431 is squeezed out through the dynamic shear hole 433 and the fixed shear hole 601. During this process, the material is subjected to strong shearing action, and the particle size is further refined.

[0048] In order to accelerate the discharge of material from the fixed shearing hole 601, in a further embodiment, the fixed shearing hole 601 is connected to the second channel 620, and the high-speed material in the second channel 620 can generate a siphon effect on the material in the fixed shearing hole 601, thereby accelerating the passage of the finely sheared material through the fixed shearing hole 601.

[0049] When the high-speed material in the second channel 620 flows through the outlet area of ​​the fixed shear hole 601, a local low-pressure zone is formed, which generates a siphon suction effect on the material in the fixed shear hole 601, accelerating the discharge of the already sheared fine material through the fixed shear hole 601, effectively preventing the material from being excessively retained and repeatedly sheared in the fine shearing area.

[0050] The first channel 610 and the second channel 620 guide the material into the fine dispersion mechanism 7, where all materials undergo final dispersion and homogenization to ensure that the fineness uniformity of the final product meets the quality requirements of foliar fertilizer products.

[0051] To ensure the shearing and siphoning effects, in a further embodiment, the moving shearing hole 433 and the fixed shearing hole 601 are perpendicular to the side of the fine shearing section 430, and the second channel 620 is parallel to the side of the fine shearing section 430. This directional arrangement increases the shearing and dispersing effect on the material.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
