Description

Technical Field

[0001] This utility model belongs to the field of mixers, specifically, it relates to a plow-type mixing mixer. Background Technology

[0002] When processing materials that require "agglomeration, shaping, or modification" through binders, plow-type mixers often involve the use of binders. These materials are usually in powder or granular form, and physical mixing alone is insufficient to meet the requirements of subsequent processing (such as granulation, tableting, molding, etc.). Binders are needed to create adhesion between the material particles, forming products with specific shapes or properties. Taking the chemical industry as an example, in the production of special plastic granules, plastic raw material powder needs to be mixed with specific binders. The binders help to tightly bind the raw material particles, thereby shaping plastic granules that meet the required shape to satisfy subsequent injection molding and other processing techniques. However, existing plow-type mixers have small internal storage volumes and poor cutting effects, which can easily lead to the discharge of large material particles that do not meet the requirements.

[0003] Chinese patent publication number CN211800517U discloses a device that uses a second discharge pipe located on the upper side of the device body. After the material is fully cut, it overflows from the second discharge pipe on the upper side. This method increases the volume inside the device body and increases the cutting time, making the cutting more thorough. The remaining material inside the device body is discharged through the first discharge pipe located at the bottom after the work is completed. However, when the device stirs materials with added binders, due to the stickiness of the binder itself, local agglomeration is prone to occur during the mixing process. The plow blade and other structural designs in the device cannot fully disperse these agglomerates, resulting in poor uniformity of the mixed material.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0039] The present invention will now be described in further detail with reference to the accompanying drawings.

[0040] Example 1

[0041] Please see Figure 1-9 As shown, this embodiment provides a plow-type mixer, including a base 1, a mixing drum 2 on top of which a main shaft 13 is rotatably mounted inside the mixing drum 2. The base 1 is provided with a drive mechanism 3 for driving the main shaft 13 to rotate. The mixing drum 2 is provided with a feed inlet 4 and a discharge outlet 5. Multiple sets of mixing rods 7 are spaced apart along the length of the main shaft 13. Adjacent mixing rods 7 are relatively staggered. Each mixing rod 7 includes a rod body 71 and a plow body 72 that are fixedly connected. Multiple protruding teeth 17 are fixedly mounted on the top of the plow body 72 along its axis. The multiple protruding teeth 17 extend along the length of the plow body 72. Multiple sets of flying knife assemblies 6 are mounted on the mixing drum 2. The multiple sets of flying knife assemblies 6 are spaced apart along the length of the mixing drum 2. The multiple sets of flying knife assemblies 6 are staggered with the multiple sets of mixing rods 7.

[0042] Specifically, the materials to be mixed (such as powders or granules) and the required binder are fed into the feed inlet 4 of the mixing drum 2. The amount of materials fed is controlled within a reasonable range of the effective volume of the mixing drum 2 (usually 40%-60%, to suit the flowability requirements of the binder materials). The drive mechanism 3 on the base 1 is started by the external control device, which drives the main shaft 13 to rotate. Multiple sets of stirring rods 7 on the main shaft 13 rotate synchronously with it. When the plow body 72 of the stirring rod 7 rotates with the main shaft 13, the multiple protruding teeth 17 at the top (extending along the length direction) shear and tumble the material. At the same time, the adjacent staggered stirring rods 7 push the material to flow axially and radially along the mixing drum 2, avoiding local accumulation, so that the material is initially mixed and forms a circulating flow. When the material is pushed to the flying knife assembly 6 area by the stirring rod 7, multiple sets of stirring rods 7 are started by the external control device. The flying knife assembly 6 (offset from the stirring rod 7 to avoid interference) uses high-speed rotating flying knives to perform secondary crushing and dispersion of residual clumps in the material (especially hard agglomerates formed by binder). The stirring time (usually 5-30 minutes) is set according to the material characteristics (such as binder viscosity and mixing uniformity requirements). Through the continuous action of the stirring rod 7 and the flying knife assembly 6, the binder and material are fully integrated. After the mixing meets the standards, the discharge port 5 is opened to discharge the mixed material. The overall structure and operation steps are simple. The design of the protruding teeth 17 on the top of the plow body 72 enhances the shearing and crushing ability against binder agglomerates, reducing localized adhesion. The arrangement of the stirring rod 7 and the flying knife assembly 6 ensures that the material flows without blind spots within the mixing drum 2, significantly reducing the problem of uneven binder distribution and thus improving mixing efficiency.

[0043] It should be noted that the mixing drum 2 is fixedly installed on the base 1, the feed inlet 4 is connected to the top of the mixing drum 2, and the discharge outlet 5 is connected to the bottom of the mixing drum 2. The feed inlet 4 and the discharge outlet 5 are located at the beginning and end of the mixing drum 2, respectively. Meanwhile, the drive mechanism 3 is a structure for driving the main shaft 13 to rotate, such as a motor. Secondly, in this embodiment, the adjacent mixing rods 7 are arranged relatively vertically, the flying knife assembly 6 is located between two adjacent sets of mixing rods 7, the plow body 72 has a plow-shaped structure, and multiple protruding teeth 17 extend from the tip of the plow body 72 to the other end. The multiple protruding teeth 17 are symmetrically arranged on both sides along the center of the plow body 72.

[0044] In this embodiment, as Figures 1 to 7 As shown, multiple sets of scraping components 9 are provided along the length of the main shaft 13. The multiple sets of scraping components 9 are staggered with multiple sets of stirring rods 7 and multiple sets of flying knife components 6. The scraping components 9 include two fixed rods 91 fixedly installed on the main shaft 13 and scrapers 92 fixedly installed on the two fixed rods 91. The scrapers 92 are in contact with the inner wall of the mixing cylinder 2. The scrapers 92 are arc-shaped structures coaxial with the mixing cylinder 2. Specifically, the scrapers 92 can be made of polyurethane material, with a gap of ≤1mm between them and the inner wall of the mixing cylinder 2. The scrapers 92 rotate synchronously with the main shaft 13 to scrape off the adhesive adhering to the inner wall of the mixing cylinder 2 in real time, so that it can re-participate in the mixing. In other embodiments, the inner wall of the cylinder can be polished to a mirror finish (roughness Ra≤0.8μm) or sprayed with a non-stick coating (such as polytetrafluoroethylene) to reduce the adhesion of the adhesive and reduce the "base" of agglomerates.

[0045] In this embodiment, as Figures 1 to 7 As shown, multiple inclined stirring plates 14 are fixedly installed on the scraper 92 along its length. Specifically, the stirring plates 14 play an auxiliary stirring role, promote the exchange of materials between the cylinder wall area and the central area, further eliminate mixing dead zones, and improve uniformity.

[0046] In this embodiment, as Figures 1 to 5As shown, the flying knife assembly 6 includes a drive motor 61, a spiral blade 63, and multiple main blades 62. The multiple main blades 62 are rotatably mounted on the mixing drum 2 via a third rotating shaft 64. The multiple main blades 62 are spaced apart on the third rotating shaft 64, which is driven by the drive motor 61. The spiral blades 63 are sleeved and fixedly mounted on the third rotating shaft 64. The multiple sets of main blades 62 and spiral blades 63 are staggered. Specifically, the drive motor 61 drives the third rotating shaft 64 to rotate, causing the multiple main blades 62 to rotate at high speed, thus creating radial shearing of the material. The helical blade 63 rotates with the third shaft 64 to break up the binder clumps, generating an axial pushing force on the material and conveying it towards the action area of ​​the main blade 62. The main blade 62 and the helical blade 63 are staggered, so that the material is continuously sheared during the pushing process, avoiding local material from not being broken. The pushing action of the helical blade 63 combined with the shearing action of the main blade 62 improves the material processing efficiency of the flying knife assembly 6. The staggered design ensures that the material is sheared from all directions, which is especially suitable for processing agglomerated materials containing high-viscosity binders and enhances the dispersion effect.

[0047] In this embodiment, as Figures 1 to 8 As shown, the rods 71 ​​of multiple sets of stirring rods 7 are rotatably mounted on the main shaft 13 via the first rotating shaft 18. The main shaft 13 is provided with an angle adjustment assembly 8 that drives the rotation of multiple first rotating shafts 18. The angle adjustment assembly 8 includes multiple worm gears 85, which are sleeved and fixedly mounted on the multiple first rotating shafts 18. A worm 83 that meshes with the multiple worm gears 85 is rotatably mounted on the main shaft 13. A driven gear 84 and a driving gear 86 are sleeved and fixedly mounted on the worm 83. The driving gear 86 is rotatably mounted on the main shaft 13 via the second rotating shaft 82. The driving gear 86 meshes with the driven gear 84. The main shaft 13 is provided with a rotating mechanism 81 for driving the rotation of the second rotating shaft 82. The diameter of the driving gear 86 is smaller than the diameter of the driven gear 84. Multiple inspection ports 12 are provided through the stirring drum 2. Each of the multiple inspection ports 12 can be detachably equipped with an inspection door 11. Specifically, the second rotating shaft 82 is driven to rotate by the rotating mechanism 81, and the driving gear 86... The driven gear 84 rotates, which in turn rotates the worm 83. The worm 83 meshes with the worm wheel 85, driving the first rotating shaft 18 to rotate, thereby adjusting the angle of the stirring rod 7 (rod body 71 and plow body 72). By controlling the rotation mechanism 81, the tilt angle of multiple sets of stirring rods 7 can be adjusted simultaneously to adapt to the stirring needs of different materials (such as binders of different viscosities). The adjustable angle of the stirring rod 7 allows the equipment to adapt to various binder materials (such as increasing the angle to enhance pushing for low-viscosity materials and decreasing the angle to enhance shearing for high-viscosity materials), improving the versatility and flexibility of the equipment and reducing the problem of uneven mixing caused by changes in material properties. Secondly, the inspection port 12 and inspection door 11 on the stirring drum 2 facilitate the maintenance, cleaning, or replacement of the internal stirring rods 7, scraping components 9, etc. It should be noted that in this embodiment, the rotating component is a worm wheel 85 and worm 83 mechanism, which is not limited in other embodiments.

[0048] In this embodiment, as Figures 1 to 8 As shown, multiple inclined plates 15 are fixedly installed on both sides of the rod 71. A protective cover 10 is detachably connected to the mixing drum 2 to protect the main shaft 13 and its angle adjustment component 8. Specifically, when the inclined plates 15 on both sides of the rod 71 rotate with the mixing rod 7, they increase the contact area with the material, forming additional shearing and pushing action on the material and enhancing the turbulence of the material. The protective cover 10 covers the main shaft 13 and the angle adjustment component 8, thus providing protection.

[0049] In this embodiment, as Figure 9 As shown, multiple arc-shaped guide plates 16 are fixedly installed on both sides of the plow body 72. A gap is defined between adjacent guide plates 16 to allow material to flow within the mixing drum 2. Specifically, the guide plates 16 extend from the tip of the plow body 72 to the other end. When the arc-shaped guide plates 16 on both sides of the plow body 72 rotate with the mixing rod 7, they guide the material to flow along the arc-shaped trajectory, changing the direction of material movement. The gap between adjacent guide plates 16 allows some material to pass through, promoting the exchange of material in different areas. The guide plates 16 optimize the material flow path and prevent local material accumulation. The gap design enhances the cross-mixing of materials, especially for materials containing binders, reducing agglomeration and improving overall uniformity.

[0050] Working principle:

[0051] Material containing binder is added through the feed inlet 4 of the mixing drum 2. Depending on the material characteristics, the angle of the stirring rod 7 can be adjusted via the angle adjustment component 8. Specifically, the rotation mechanism 81 drives the second rotating shaft 82 to rotate. The driving gear 86 drives the driven gear 84 and worm gear 83 to rotate. The worm gear 83 meshes with the worm wheel 85, causing the first rotating shaft 18 to rotate, thereby adjusting the tilt angle of the rod body 71 and the plow body 72. Simultaneously, the protective cover 10 protects the main shaft 13 and the angle adjustment component 8. Then, the drive mechanism 3 on the base 1 is activated via an external control device, driving the main shaft 13 to rotate inside the mixing drum 2. The main shaft 13 drives multiple sets of stirring rods 7 and scraping components 9 to rotate synchronously. Simultaneously, multiple sets of flying knife components 6 are activated, driving the motor 61 to drive the third rotating shaft 64 to rotate, causing the main blade 62 and spiral blade 63 to rotate at high speed. The plow body 72 of the stirring rod 7... The top protrusion 17 pierces the material agglomerates, the arc-shaped guide plates 16 on both sides guide the material flow, the inclined plates 15 on both sides of the rod 71 enhance the material disturbance and further disperse the bonded agglomerates, the main blade 62 of the flying knife assembly 6 cuts the agglomerates at high speed, the spiral blade 63 pushes the material to make the dispersion more uniform, and is staggered with the stirring rod 7 to avoid interference, the scraper 92 of the scraper assembly 9 is attached to the inner wall of the mixing drum 2 to scrape away the bonded material and prevent the inner wall from agglomerating, the inclined stirring plate 14 on the scraper 92 enhances the secondary mixing of the scraped material, after the mixing is completed, the discharge port 5 is opened, and the material is discharged under the action of the stirring rod 7 and the scraper assembly 9. If it is necessary to inspect and maintain the internal equipment of the mixing drum 2, the inspection door 11 can be opened to maintain the internal structure. The overall structure is simple to operate, can efficiently disperse agglomerates, enhance material convection mixing, prevent wall adhesion and agglomeration, thereby improving the overall mixing uniformity.

[0052] Example 2

[0053] Unlike Embodiment 1, in this embodiment, as Figure 10 As shown, multiple arc-shaped baffles 19 are fixedly installed on both sides of the plow body 72. The multiple baffles 19 on each side of the plow body 72 define multiple gaps in the horizontal and vertical directions to allow the material to flow in the mixing drum 2. Specifically, when the arc-shaped baffles 19 on both sides of the plow body 72 rotate with the stirring rod 7, they disrupt the normal flow direction of the material and form multi-directional turbulence. The gaps in the horizontal and vertical directions allow the material to flow crosswise between the baffles 19, increasing the collision and mixing frequency of materials in different areas. Especially for materials coated with binders, it can promote the uniform distribution of binders. The baffles 19 enhance the turbulence of the material and break the stability of binder agglomeration. The horizontal and vertical gaps promote all-round mixing of materials and significantly improve the mixing uniformity of materials containing binders.
