[0051] The present invention will be described more specifically by way of example in the following paragraphs with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0052] The following is in conjunction with the instruction manual appendix. Figure 1 To be continued Figure 12 This paper introduces the pulverizing and emulsifying machine of this utility model.

[0053] In some of these embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the pulverizing emulsifier includes a pulverizing cylinder 100 and a drive mechanism, and also includes a frame 300. The pulverizing cylinder 100 and the drive mechanism are both mounted on the frame 300.

[0054] The crushing cylinder 100 has a feed inlet and a discharge outlet 110.

[0055] The crushing cylinder 100 contains a primary crushing component and a secondary crushing component that are interconnected, arranged sequentially from top to bottom.

[0056] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the primary crushing assembly includes a screen cage 410 and an impeller 420 located in the screen cage 410, the impeller 420 having a plurality of blades 421 arranged circumferentially.

[0057] like Figure 8 and Figure 9 As shown, the secondary crushing component includes a fixed toothed component 510 and a movable toothed component 520 nested together, and both the fixed toothed component 510 and the movable toothed component 520 have multiple shearing teeth arranged at intervals along the circumference.

[0058] The drive mechanism is used to drive the impeller 420 and the moving gear 520 to rotate.

[0059] This utility model's pulverizing emulsifier achieves progressive pulverization of materials through a two-stage pulverizing structure. In the first-stage pulverizing component, the blades 421 of the high-speed rotating impeller 420 cooperate with the screen cage 410 to achieve initial shearing and pulverization. In the second-stage pulverizing component, the shearing teeth of the moving toothed component 520 and the stationary toothed component 510 cooperate to form secondary fine pulverization. The drive mechanism synchronously drives the two-stage pulverizing components to ensure pulverizing efficiency. The setting of the feed inlet and discharge outlet 110 enables continuous production. Through the synergistic effect of the first-stage coarse pulverization and the second-stage fine pulverization, the particle size of the material is effectively reduced and the uniformity is improved. It has advantages such as high pulverizing efficiency and good particle uniformity, and is particularly suitable for applications in the food and pharmaceutical industries where the fineness of material pulverization is required.

[0060] Specifically, the screen cage 410 can adopt a cylindrical or conical structure, and its inner wall can be provided with protrusions 411 or grooves to enhance the shearing effect. The number of blades 421 of the impeller 420 can be adjusted according to the material characteristics, for example, 3-8 blades 421 can be set. The blades 421 can adopt a straight blade or an arc blade design, with the arc blade being more conducive to material flow. The shearing teeth of the fixed toothed component 510 and the moving toothed component 520 can adopt a triangular, trapezoidal or other polygonal structure, and the tooth spacing can be specifically set according to the grinding fineness requirements. The drive mechanism can use a motor to drive the impeller 420 and the moving toothed component 520 to rotate synchronously through belt or gear transmission.

[0061] In some of these embodiments, such as Figure 4 , Figure 5 , Figure 6and Figure 7 As shown, the inner wall of the sieve cage 410 is provided with a plurality of protrusions 411 at intervals, and the blade of the blade 421 is adjacent to the protrusions 411 to form a shearing gap 412, which is used to shear and crush the material.

[0062] The protrusions 411 can take the form of triangles, trapezoids, or semicircles, and are evenly distributed along the circumference of the inner wall of the screen cage 410. The number of protrusions 411 can be greater than the number of blades 421. The width of the shearing gap 412 can be specifically set according to the size of the material being crushed, and the gap can be adjusted by adjusting the installation angle of the blades 421 or the height of the protrusions 411. As a preferred embodiment, the protrusions 411 are made of wear-resistant alloy material.

[0063] In this embodiment, a precisely controllable shearing gap 412 is formed between the protrusions 411 on the inner wall of the screen cage 410 and the rotating blades 421. When the blades 421 rotate at high speed, the material is forced through the shearing gap 412 and subjected to mechanical shearing action between the protrusions 411 and the blades 421. Specifically, the arrangement of the protrusions 411 causes the material to undergo multiple shearing processes during the crushing process, avoiding the uneven particle size caused by traditional crushers relying solely on the impact of the blades 421. The resulting shearing force field effectively breaks up material agglomerates, resulting in a more concentrated particle size distribution. Compared with crushing methods that rely solely on the impact of the blades 421, the shearing intensity and frequency are significantly improved, thereby improving the uniformity of crushing.

[0064] In some embodiments, the inner wall of the screen cage 410 is provided with a primary flow channel for material to pass through.

[0065] By setting a primary flow channel on the inner wall of the screen cage 410, a flow path is provided for the material, preventing the material from accumulating or clogging inside the screen cage 410. When the impeller 420 rotates, the material is thrown towards the inner wall of the screen cage 410 under the action of centrifugal force. The primary flow channel can guide the orderly flow of the material, ensuring that the material is evenly distributed inside the screen cage 410.

[0066] Furthermore, such as Figure 4 As shown, the sieve cage 410 includes an inner cage 413 and an outer cage 414 arranged at intervals and fixedly connected. The inner wall of the inner cage 413 is provided with a plurality of window units 415. There is an annular cavity 416 between the inner cage 413 and the outer cage 414. The window units 415 and the annular cavity 416 constitute the primary flow channel.

[0067] Specifically, the window unit 415 can be a circular, square, elliptical, or other regular-shaped through hole, and its size and distribution density are designed according to the material characteristics. The window units 415 are arranged on the inner wall of the inner cage 413 in a uniform, spiral, or zoned concentrated manner. The specific dimensions of the radial width of the annular cavity 416 are adjusted according to the viscosity and flowability of the crushed material. The inner cage 413 and the outer cage 414 are connected by radial support ribs, and the cross-sectional shape of the support ribs is rectangular, trapezoidal, or streamlined. The edges of the window unit 415 can be provided with guide slopes, and the angle of the guide slopes is preferably 30-60 degrees. The inner cage 413 and the outer cage 414 are made of stainless steel or hard alloy materials.

[0068] In this embodiment, a double-cage structure forms an annular cavity 416, which, together with the inner cage 413 and window unit 415, constitutes a composite flow channel. Driven by the impeller 420, the material enters the annular cavity 416 through the window unit 415, forming a circumferential flow, and finally enters the earphone crushing assembly. The window unit 415 controls the proportion of material entering the annular cavity 416, and the annular cavity 416 provides a buffer space to balance the flow pressure difference, thereby improving the material throughput efficiency and the uniformity of the material particle size distribution.

[0069] In some of these embodiments, such as Figure 8 and Figure 9 As shown, the shearing teeth of the movable gear 520 form a movable gear ring 521, and the shearing teeth of the fixed gear form a fixed gear ring 511. The fixed gear ring 511 and the movable gear ring 521 are arranged coaxially and spaced apart from each other, and a movement gap is formed between the fixed gear ring 511 and the movable gear ring 521.

[0070] Specifically, the moving gear ring 521 and the fixed gear ring 511 can adopt an alternating rectangular, triangular, or trapezoidal shearing tooth structure, with a movement gap formed between the inner and outer moving gear rings 521. The distance between the shearing teeth and the width of the movement gap can be set to different dimensions as needed. The rotational speed of the moving gear ring 521 can be controlled within a reasonable range, creating a speed difference with the fixed gear ring 511 to enhance the shearing effect.

[0071] The coaxial arrangement of the moving gear ring 521 and the fixed gear ring 511 ensures a uniform distribution of the shear force field, while the inner and outer spacing structure extends the residence time of the material in the crushing zone. Through multi-stage shearing action, the material is subjected to continuously varying shear forces, avoiding local over-crushing or under-crushing. The material is fully crushed as it passes through the moving gap, effectively solving the problem of uneven crushing in traditional equipment and significantly improving crushing efficiency. The design of the moving gap allows the material to undergo repeated shearing and compression during passage, contributing to finer particle sizes and a more uniform particle size distribution.

[0072] Furthermore, in some embodiments, the shearing teeth of the moving gear 520 form at least two coaxial and spaced-apart moving gear rings 521, and a movement gap is also formed between two adjacent moving gear rings 521.

[0073] Specifically, the number of moving toothed rings 521 can be two, three, or more, selected according to actual crushing requirements. As a preferred embodiment, the spacing between the moving toothed rings 521 can be adjusted according to the material properties and crushing requirements. For example, for materials with high hardness, the spacing can be appropriately reduced to enhance the crushing effect. The moving toothed rings 521 can be arranged with equal or unequal intervals, with equal intervals facilitating uniform crushing. The tooth shape of the moving toothed rings 521 can be rectangular, triangular, trapezoidal, or other shapes suitable for crushing, and the tooth height and pitch can be optimized according to crushing requirements.

[0074] This embodiment's technical solution, by setting up multi-stage coaxial moving toothed rings 521, allows materials to sequentially pass through multiple crushing zones during the crushing process. The material first enters the innermost moving toothed ring 521 for initial crushing, then enters the movement gap between adjacent moving toothed rings 521 for secondary crushing, and finally completes final crushing through the outer moving toothed ring 521 and the fixed toothed ring 511. This multi-stage crushing structure significantly increases the contact opportunities between the material and the shearing teeth and the crushing path length, allowing the material to be more thoroughly crushed. This effectively improves crushing efficiency and particle uniformity, making it particularly suitable for processing materials requiring high fineness and uniformity.

[0075] In some of these embodiments, such as Figure 1 , Figure 10 and Figure 11 As shown, the pulverizing emulsifier also includes an overflow feed cylinder 600. The lower end of the overflow feed cylinder 600 is fixedly connected to and communicates with the feed inlet of the pulverizing cylinder 100. The overflow feed cylinder 600 includes an inner feed cylinder 610 and an outer feed cylinder 620 arranged at intervals along the inside and outside, and an overflow gap 630 is formed between the two. The upper opening of the outer feed cylinder 620 is higher than the upper opening of the inner feed cylinder 610. The overflow feed cylinder 600 has a liquid inlet 621 and a solid inlet 622. The liquid inlet 621 is located on the side wall of the outer feed cylinder 620 and is lower than the upper opening of the inner feed cylinder 610. The upper opening of the outer feed cylinder 620 forms the solid inlet 622.

[0076] Specifically, the inner feed cylinder 610 and the outer feed cylinder 620 can be coaxially fitted cylindrical structures, and their spacing can be set according to requirements to form an overflow gap 630. The liquid inlet 621 can be set as a circular opening, with its center position lower than the upper edge of the inner feed cylinder 610. The diameter of the solid inlet 622 needs to meet the feeding requirements of solid materials with different particle sizes. The width of the overflow gap 630 can be adjusted by replacing shims of different thicknesses to accommodate materials of different viscosities. The overflow feed cylinder 600 can be fixedly connected to the crushing cylinder 100 by a clamp 120.

[0077] This embodiment achieves stratified feeding of solid and liquid materials through physically isolated feeding channels. Solid materials enter the outer feeding cylinder 620 from the high-level inlet, while liquid materials are injected from the low-level inlet on the side wall, achieving automatic diversion using gravity. The overflow gap 630 not only adjusts the feeding speed but also creates an overflow when the liquid level exceeds the height of the inner feeding cylinder 610, ensuring continuous feeding while preventing blockage. The structural design of the inner and outer feeding cylinders 620 allows the solid and liquid materials to undergo preliminary mixing before entering the crushing cylinder 100, effectively improving the uniformity of the mixing of solid and liquid materials. Compared with existing technologies, this embodiment significantly improves feeding uniformity through structured separation and gravity diversion principles, while avoiding inlet blockage.

[0078] In some embodiments, the crushing cylinder 100 includes a feeding section and a crushing section arranged sequentially from top to bottom and detachably connected, with the feeding port located in the feeding section and the discharge port 110 located in the crushing section.

[0079] Specifically, detachable connections can be achieved using flange bolt connections or snap-fit ​​connections. Flange bolt connections, where flanges are mated and bolts are tightened, offer stable connections and easy disassembly. Snap-fit ​​connections utilize elastic clips and grooves for quick assembly and disassembly. The separate design of the feeding section and crushing section allows for the use of different materials; for example, the feeding section can use wear-resistant alloy steel to withstand material impact, while the crushing section can use stainless steel to meet hygiene requirements.

[0080] This embodiment divides the crushing cylinder 100 into an independently detachable feeding section and a crushing section, allowing for segmented repairs to address issues such as blockages and wear during equipment maintenance, eliminating the need for complete disassembly. For example, when the feed inlet is blocked, only the feeding section needs to be disassembled for cleaning; when the crushing section blades are worn, the crushing section components can be replaced individually. This significantly reduces maintenance workload and shortens downtime.

[0081] In some of these embodiments, such as Figure 1 and Figure 12As shown, the portion of the crushing cylinder 100 near the discharge port 110 is a temperature-controlled jacket section 130. The temperature-controlled jacket section 130 has a jacket space 133 and a medium inlet 131 and a medium outlet 132 communicating with the jacket space 133. The jacket space 133 is used to contain the temperature-controlled medium.

[0082] Specifically, the temperature-controlled jacket section 130 can adopt a double-shell structure, forming a jacket space 133 between the inner and outer shells. The thickness of the jacket space 133 can be designed according to the heat exchange efficiency requirements. The medium inlet 131 and the medium outlet 132 can be located at the upper and lower ends of the jacket to form a convection circulation. The temperature-controlled medium can be water, heat transfer oil, or refrigerant, depending on the temperature control range. Stainless steel is preferred for the jacket material, considering both corrosion resistance and thermal conductivity. A temperature sensor can be installed near the discharge port 110 to link with an external temperature control system to adjust the medium temperature, which is beneficial for improving material quality.

[0083] In some embodiments, the drive mechanism includes a drive member 210 and a drive shaft 220 driven by the drive member 210, wherein the impeller 420 and the moving gear ring 521 are fixedly connected to the drive shaft 220.

[0084] The drive unit 210 can be a power device such as an electric motor or a hydraulic motor, and the drive shaft 220 can be a rigid transmission shaft or a segmented coupling structure. The impeller 420 is fixed to the upper end of the drive shaft 220 by a key connection or a flange connection, and the moving gear ring 521 can also be fixed to the lower end of the drive shaft 220 by a key connection or a flange connection. As a preferred embodiment, the drive shaft 220 can be provided with an axial positioning step to restrict the installation positions of the impeller 420 and the moving gear ring 521 respectively.

[0085] In operation, the drive unit 210 acts as a power source, outputting rotational torque, which is simultaneously transmitted to the impeller 420 and the moving gear ring 521 via the drive shaft 220. Because the impeller 420 and the moving gear ring 521 are coaxially fixedly connected, the rotational speed of the blades 421 in the first-stage crushing component is strictly synchronized with the rotational speed of the shearing teeth in the second-stage crushing component. When the drive shaft 220 rotates at a constant speed, the shearing gap 412 formed between the impeller blades 421 and the protrusions 411 inside the screen cage 410 generates continuous shearing action. Simultaneously, the movement gap formed between the moving gear ring 521 and the fixed gear ring achieves synchronous crushing. The high timing matching accuracy of the two-stage crushing actions is beneficial for improving crushing efficiency and particle uniformity.

[0086] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
