[0002] Material mixers are indispensable key equipment in many industries such as chemical, food, pharmaceutical, and building materials, used to uniformly mix various raw materials or components.

[0003] Traditional material mixers, such as horizontal ribbon mixers, V-type mixers, or vertical mixing mixers, can meet basic mixing needs, but cleaning the material adhering to the inner wall of the mixer is very inconvenient, thus affecting the use of the machine. Summary of the Invention

[0004] The purpose of this invention is to provide a material mixer that facilitates internal cleaning, thereby solving the problems mentioned in the background art.

The sealing cover is positioned directly above the opening at the top of the mixing drum to seal it, and its top is connected to the component mounting cylinder. A stirring and cleaning mechanism is mounted on the position adjustment mechanism to drive the stirring and mixing of materials inside the mixing drum and facilitate cleaning of the drum's inner wall. The stirring and cleaning mechanism includes: a movable plate positioned inside the component mounting cylinder; a pair of mounting ears positioned symmetrically on both sides of the outer wall of the component mounting cylinder, with a second telescopic rod embedded in one end of each mounting ear, the bottom of which is connected to the movable plate; a rotating shaft rotatably mounted on the movable plate, and a rotation drive assembly for driving the rotating shaft to rotate is also mounted on the movable plate; and a first connection. The system comprises a first connecting cylinder located at the bottom of a rotating shaft, with its bottom connected to a second connecting cylinder via a connecting rod. A bottom cleaning assembly for cleaning the arc-shaped surface at the bottom of the second connecting cylinder is detachably installed on its bottom. A pair of movable frames are symmetrically arranged, with their ends inserted into the first and second connecting cylinders respectively. Each movable frame has several equally spaced drainage recesses, each containing a passive stirring blade. A moving drive assembly, mounted on the connecting rod, drives the movable frames to reciprocate in and out synchronously. The rotating shaft is driven by the drive assembly to rotate the first connecting cylinder, the connecting rod, and the second connecting cylinder. Simultaneously, the second connecting cylinder drives the movable frames at both ends to rotate, stirring the material. As the material passes through the drainage recesses, the passive stirring blades rotate, creating turbulent flow. The moving drive assembly simultaneously adjusts the inward and outward orientation of the movable frames, accelerating the mixing of the material.

[0006] Preferably, the bottom of the mixing cylinder is provided with a discharge assembly for discharging the material after mixing; the discharge assembly includes a discharge pipe, which is located at the center of the bottom of the mixing cylinder, and a control valve is installed on the discharge pipe.

[0007] Preferably, a connecting plate is provided at the outer end of the top opening of the mixing cylinder, a sealing groove is provided on the top of the connecting plate, and a plurality of insertion holes are provided at equal intervals on the connecting plate located outside the sealing groove; a sealing protrusion is provided at the outer end of the bottom of the sealing cover, and a plurality of insertion posts are installed at the bottom of the sealing cover located outside the sealing protrusion.

[0008] Preferably, a support frame is installed on the mixing cylinder located at the bottom of the connecting plate, and an electrical control box is also installed on the support frame.

[0009] Preferably, the orientation adjustment mechanism further includes a sliding frame, which is placed at the four corners of the outer wall of the component mounting cylinder, and a sliding sleeve is provided at the bottom of the sliding frame, which is slidably connected to the support frame; and a fixing block, which is placed at the bottom of the support frame, with a first telescopic rod embedded in one end of the fixing block, the top of the first telescopic rod being connected to the sliding frame, and guide rods fixedly provided on the fixing blocks at the other three ends, which are slidably connected to the sliding frame.

[0010] Preferably, a limiting rod is slidably provided on the mounting ear at the other end, and the bottom of the limiting rod is fixedly connected to the movable plate.

[0011] Preferably, the rotation drive assembly includes a mounting block placed on a movable plate, and a rotation motor is mounted on the mounting block. A first bevel gear is mounted on the motor shaft of the rotation motor, and a second bevel gear is meshed with the first bevel gear and connected to the rotation shaft.

[0012] Preferably, the bottom cleaning assembly includes a mounting base placed at the bottom of the second connecting cylinder, and a mounting rod provided at the bottom of the mounting base; it also includes a fixing frame, the bottom of which is provided with a flexible cleaning pad for cleaning the arc-shaped surface at the bottom of the mixing cylinder; the fixing frame is threadedly connected to the bottom of the mounting rod, and a brake nut is installed on the mounting rod located at the bottom of the fixing frame.

[0013] Preferably, the moving drive assembly includes a mounting sleeve, which is placed at the center of the connecting rod, and a double-headed telescopic rod is embedded inside the mounting sleeve, with the two telescopic ends of the double-headed telescopic rod connected to the moving frame.

[0014] Preferably, stirring rods are symmetrically arranged on the connecting rods located on both sides of the double-headed telescopic rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes a lifting and radially extendable stirring and cleaning mechanism. During mixing, it functions as a high-efficiency stirrer. When cleaning is required, the moving frame and bottom cleaning component can be driven to fit against the vertical inner wall and bottom arc surface of the mixing drum, respectively. The rotating mechanism performs scraping cleaning, thus realizing that the stirring component is also the cleaning component. There is no need for additional disassembly or the introduction of other cleaning devices. This solves the problems of many dead corners and cumbersome disassembly in traditional mixers, and facilitates the operation of the material mixing drum. The moving frame of the stirring mechanism of the present invention is provided with a drainage recess with a passive stirring blade. When rotating and stirring, the fluid passes through the drainage recess and drives the passive stirring blade to rotate, generating local turbulence in the main flow, breaking the laminar flow state, greatly enhancing the shearing, convection and diffusion of the material, and significantly accelerating the mixing speed. It is especially suitable for materials that are not easy to mix evenly. This invention achieves overall lifting and lowering of the stirring and cleaning mechanism through an orientation adjustment mechanism, which facilitates feeding, observation and maintenance. The stirring shaft is finely adjusted through the second telescopic rod to ensure that the bottom cleaning component is adapted to the bottom of the tank. The radial extension and retraction of the moving frame is controlled by the moving drive component to achieve switching of working states, thereby facilitating the rapid mixing and processing of materials. The seal between the mixing cylinder and the sealing cap of the present invention ensures the sealing performance of the mixing process, especially during stirring and cleaning, preventing material leakage or splashing of cleaning fluid, and meeting the sealing requirements of different working conditions. The bottom cleaning component of this invention adopts a detachable flexible cleaning pad design, which is easy to replace after wear, reducing maintenance costs. The main transmission components are located on the outside or top of the cylinder, and are less affected by material wear and corrosion, thus improving the reliability and service life of the whole machine.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of the present invention to facilitate a better understanding of this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0027] See Figures 1-7In this embodiment of the invention, a material mixer for easy internal cleaning includes a mixing drum 1 and a position adjustment mechanism 2. The position adjustment mechanism 2 is slidably mounted on the top of the mixing drum 1. The mixing drum 1 includes a component mounting cylinder 21 and a sealing cover 25. The sealing cover 25 is positioned directly above the opening at the top of the mixing drum 1 to seal the mixing drum 1, and the top of the sealing cover 25 is connected to the component mounting cylinder 21. A stirring and cleaning mechanism 3 is also included, positioned on the position adjustment mechanism 2, for driving the stirring and mixing of the material inside the mixing drum 1. And facilitates cleaning of the inner wall of the mixing cylinder 1; the stirring and cleaning mechanism 3 includes: a movable plate 31, which is placed inside the component mounting cylinder 21; a pair of mounting ears 32, which are placed on both sides of the outer wall of the component mounting cylinder 21 and are symmetrically arranged, with a second telescopic rod 33 embedded on one end of the mounting ear 32, the bottom of the second telescopic rod 33 being connected to the movable plate 31; a rotating shaft 35, which is rotatably mounted on the movable plate 31, and the movable plate 31 is also equipped with a rotation drive assembly 36 for driving the rotating shaft 35 to rotate; and a first connecting cylinder 37. The first connecting cylinder 37 is located at the bottom end of the rotating shaft 35, and the bottom of the first connecting cylinder 37 is connected to the second connecting cylinder 39 via a connecting rod 38. A bottom cleaning assembly 310 for cleaning the arc-shaped surface at the bottom of the mixing cylinder 1 is detachably installed on the bottom of the second connecting cylinder 39. A pair of movable frames 311 are arranged symmetrically, with their ends inserted into the first connecting cylinder 37 and the second connecting cylinder 39 respectively. Each movable frame 311 has several equally spaced drainage recesses 312 inside, and a passive stirring blade 313 is installed inside each drainage recess 312. The driving component 314 is mounted on the connecting rod 38 and is used to drive the moving frame 311 to move back and forth synchronously. By rotating the driving component 36, the rotating shaft 35 is driven to rotate the first connecting cylinder 37, the connecting rod 38 and the second connecting cylinder 39. The second connecting cylinder 39 synchronously drives the moving frames 311 at both ends to rotate and stir the material. During the process of the material passing through the drain notch 312, the passive stirring blade 313 is driven to rotate to form a stirring turbulence. At the same time, the moving component 314 is used to drive the moving frame 311 to adjust its internal and external orientation, which accelerates the mixing of the material.

[0028] This invention uses an orientation adjustment mechanism 2 to drive a stirring and cleaning mechanism 3 to adjust its vertical movement. During this vertical movement, the stirring and cleaning mechanism 3 uses a second telescopic rod 33 to drive a moving plate 31. The moving plate 31 then drives a rotating shaft 35 to move vertically accordingly. A rotation drive assembly 36 drives the rotating shaft 35 to rotate, which in turn drives the first connecting cylinder 37, the connecting rod 38, and the second connecting cylinder 39 to rotate. Simultaneously, the rotating frames 311 at both ends rotate and stir the material. The material then passes through a drainage notch 312 on the moving frame 311. The material inside the drain recess 312 drives the passive stirring blade 313 to rotate. The passive stirring blade 313 rotates the material to generate turbulence, thereby accelerating the mixing efficiency of the material. After the material is mixed, the bottom cleaning component 310 is installed at the bottom of the second connecting cylinder 39, and the moving frame 311 is driven to move outward and contact the inner wall of the mixing cylinder 1 by the moving drive component 314. The rotating shaft 35 is driven to rotate by the rotation drive component 36. The rotating shaft 35 drives the moving frames 311 at both ends to rotate synchronously through the first connecting cylinder 37, the connecting rod 38 and the second connecting cylinder 39. The outer end of the moving frame 311 rotates and scrapes the inside of the mixing cylinder 1. The bottom cleaning component 310 rotates synchronously with the second connecting cylinder 39 to clean the arc-shaped surface at the bottom of the mixing cylinder 1, thereby realizing the rapid cleaning of the inside of the material mixer and facilitating the use of the mixer.

A sealing groove 121 is provided on the top of the connecting plate 12, and a plurality of insertion holes 122 are provided at equal intervals on the connecting plate 12 located outside the sealing groove 121. A sealing protrusion ring 251 is provided at the bottom outer end of the sealing cover 25, and a plurality of insertion posts 252 are installed at the bottom of the sealing cover 25 located outside the sealing protrusion ring 251. The arrangement of the sealing groove 121 and the sealing protrusion ring 251, as well as the arrangement of the plurality of insertion posts 252 and the insertion holes 122, can realize the sealing of the top opening of the mixing cylinder 1 by the sealing cover 25.

[0031] See Figure 3In one embodiment of the present invention, a support frame 13 is installed on the mixing cylinder 1 located at the bottom of the connecting plate 12, and an electrical control box 14 is also installed on the support frame 13.

[0032] See Figure 2 and Figure 4 In one embodiment of the present invention, the orientation adjustment mechanism 2 further includes a sliding frame 22, which is placed at the four corners of the outer wall of the component mounting cylinder 21, and a sliding sleeve 221 is provided at the bottom of the sliding frame 22, which is slidably connected to the support frame 13; a fixing block 26, which is placed at the bottom of the support frame 13, with a first telescopic rod 24 embedded in one end of the fixing block 26, the top of the first telescopic rod 24 being connected to the sliding frame 22, and guide rods 23 being fixedly provided on the fixing blocks 26 at the other three ends, which are slidably connected to the sliding frame 22. The first telescopic rod 24 is used to drive the sliding frame 22 to make adaptive up-down movement and height adjustment under the guidance of the guide rods 23.

[0033] See Figure 2 In one embodiment of the present invention, a limiting rod 34 is slidably provided on the mounting ear 32 at the other end. The bottom of the limiting rod 34 is fixedly connected to the moving plate 31. During the movement of the moving plate 31, the limiting rod 34 limits the moving plate 31, thereby ensuring that the moving plate 31 can move up and down adaptively.

[0034] See Figure 2 In one embodiment of the present invention, the rotation drive assembly 36 includes a mounting block 361, which is placed on a movable plate 31.

When the rotation motor 362 operates, it drives the first bevel gear 363 to rotate. The first bevel gear 363 drives the meshed second bevel gear 364 to rotate. The second bevel gear 364 can drive the rotation shaft 35 to rotate horizontally.

[0035] See Figure 5In one embodiment of the present invention, the bottom cleaning assembly 310 includes a mounting base 3101, which is placed at the bottom of the second connecting cylinder 39, and a mounting rod 3102 is provided at the bottom of the mounting base 3101; it also includes a fixing frame 3103, and a flexible cleaning pad 3105 for cleaning the arc-shaped surface at the bottom of the mixing cylinder 1 is provided at the bottom of the fixing frame 3103; the fixing frame 3103 is threadedly connected to the bottom of the mounting rod 3102, and a brake nut 3104 is installed on the mounting rod 3102 located at the bottom of the fixing frame 3103. By connecting the top of the mounting rod 3102 to the mounting base 3101, and threading the fixing frame 3103 to the bottom of the mounting rod 3102, and using the brake nut 3104 to achieve a stable connection between the fixing frame 3103 and the mounting rod 3102, the flexible cleaning pad 3105 can be detachably installed.

[0036] See Figure 6 In one embodiment of the present invention, the moving drive assembly 314 includes a mounting sleeve 3141, which is placed at the center of the connecting rod 38, and a double-headed telescopic rod 3142 is embedded inside the mounting sleeve 3141. The two telescopic ends of the double-headed telescopic rod 3142 are connected to the moving frame 311. By working through the double-headed telescopic rod 3142, the moving frames 311 at both ends can be driven to make adaptive movement and orientation adjustments.

[0037] See Figure 6 In one embodiment of the present invention, stirring rods 315 are symmetrically arranged on the connecting rods 38 located on both sides of the double-headed telescopic rod 3142. The arrangement of stirring rods 315 can increase the stirring and mixing efficiency of the entire stirring and cleaning mechanism 3, thereby facilitating the stirring operation of the material mixer.

[0038] Working principle: The present invention controls the entire material mixer to operate safely through the electrical control box 14. The material is fed into the mixing drum 1 in sequence. The electrical control box 14 controls the first telescopic rod 24 to work. The first telescopic rod 24 drives the sliding frame 22 to move downward under the guidance of the guide rod 23. The sliding frame 22 drives the sealing cover 25 and the component mounting cylinder 21 to move downward. The sealing protrusion ring 251 and the insertion post 252 set at the bottom of the sealing cover 25 move downward and are inserted into the sealing groove 121 and the insertion hole 122, thereby realizing the sealing connection between the mixing drum 1 and the sealing cover 25. The rotating motor 362 is controlled by the electrical control box 14. The rotating motor 362 drives the first bevel gear 363 to work. The first bevel gear 363 drives the meshing second bevel gear 364 to rotate. The second bevel gear 364 drives the rotating shaft 35 to rotate. The rotating shaft 35 drives the first connecting cylinder 37, the connecting rod 38, the second connecting cylinder 39, and the symmetrically arranged moving frame 311 to rotate and mix the materials. The stirring rods 315 symmetrically arranged on the connecting rod 38 will also rotate synchronously to mix the materials. During the process of rotating and stirring the material, the material is discharged through the drain recess 312 opened on the moving frame 311. The passive stirring blade 313 set inside the drain recess 312 will rotate with the flowing material to form turbulence, thereby accelerating the mixing of the material. The double-headed telescopic rod 3142 is controlled by the electrical control box 14. The double-headed telescopic rod 3142 drives the moving frames 311 at both ends to adjust their inward and outward movement at the first connecting cylinder 37 and the second connecting cylinder 39, thereby facilitating the rapid mixing of the material. After the material is mixed, the discharge pipe 111 is opened by operating the control valve 112 through the electrical control box 14, and the discharge pipe 111 can conveniently discharge the mixed material in sequence. The first telescopic rod 24 is controlled by the electrical control box 14 to work. The first telescopic rod 24 drives the sliding frame 22 to move upward, and the electrical control box 14 controls the second telescopic rod 33 to drive the moving plate 31 to move upward synchronously. This allows the stirring and cleaning mechanism 3 to be moved above the mixing cylinder 1. The top of the mounting rod 3102 is connected to the mounting base 3101, and the fixing frame 3103 is placed at the bottom of the mounting rod 3102. The mounting rod 3102 and the fixing frame 3103 are stably connected by the brake nut 3104. This allows the second connecting cylinder 39 to be stably connected to the flexible cleaning pad 3105. The first telescopic rod 24 is controlled by the electrical control box 14 to work. The first telescopic rod 24 drives the sliding frame 22 to move downward. The sliding frame 22 drives the component mounting cylinder 21 and the sealing cover 25 to move downward. The sealing protrusion ring 251 and the insertion post 252 at the bottom of the sealing cover 25 are inserted into the sealing groove 121 and the insertion post 252 is inserted into the insertion hole 122, so that the sealing cover 25 seals the top opening of the mixing cylinder 1. Then, the electrical control box 14 controls the second telescopic rod 33 to drive the moving plate 31 to move downward synchronously. The moving plate 31 drives the first connecting cylinder 37 to move downward through the rotating shaft 35. The first connecting cylinder 37 drives the flexible cleaning pad 3105 to make close contact with the arc surface at the bottom of the mixing cylinder 1 through the connecting rod 38, the second connecting cylinder 39, and the mounting rod 3102. The electrical control box 14 controls the double-headed telescopic rod 3142 to work. The double-headed telescopic rod 3142 drives the moving frames 311 at both ends to move outward and contact the vertical inner wall of the mixing cylinder 1. The rotating motor 362 is controlled by the electrical control box 14. The rotating motor 362 drives the first bevel gear 363 to work. The first bevel gear 363 drives the meshing second bevel gear 364 to rotate. The second bevel gear 364 drives the rotating shaft 35 to rotate. The rotating shaft 35 drives the first connecting cylinder 37, the connecting rod 38, the second connecting cylinder 39, and the symmetrically arranged moving frame 311 to perform rotational cleaning of the vertical inner wall of the mixing cylinder 1. The second connecting cylinder 39 and the mounting rod 3102 drive the flexible cleaning pad 3105 to perform rotational cleaning of the arc-shaped surface of the inner wall of the mixing cylinder 1. This makes it easier to clean the inner wall of the mixing cylinder 1 and facilitates the operation of the entire material mixer.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
