Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a compound mixing mixer. Background Technology

[0002] A compound mixer is a device used to uniformly mix multiple compounds, widely used in chemical, pharmaceutical, and food processing industries. Depending on the specific application, mixers come in various structural forms and technical features. Their core function is to achieve thorough mixing of materials through mechanical motion to meet the requirements of subsequent processes. As industrial production demands increasingly higher efficiency and quality, the design of mixers is constantly being optimized, and materials and technologies are continuously being updated. However, in some practical applications, existing mixers may suffer from low mixing efficiency or complex operation, leading to longer production cycles and increased energy consumption.

[0003] Currently, some mixers improve mixing efficiency through complex transmission mechanisms or multi-stage mixing devices. However, such designs often require additional power or occupy a large space, increasing the cost of equipment manufacturing and maintenance. Furthermore, some equipment, when processing specific compounds, may fail to fully meet homogeneity requirements due to a single mixing method, thus affecting the quality of the final product.

[0004] The inventors discovered during their research and development of related equipment that existing mixing mixers still have room for improvement in terms of increasing mixing efficiency and reducing energy consumption, especially in terms of reducing reliance on power sources and optimizing structural design.

[0026] The specific embodiments of this compound mixing and stirring machine are described in detail with reference to the accompanying drawings.

A drive box 3 is located in the middle of the support frame 2, and the drive box 3 is fixedly connected to the support frame 2 with bolts to ensure stability. A transmission mechanism is installed inside the drive box 3, including a motor 16, a reducer 17, and a gear set 18. The output shaft of the motor 16 is connected to the input end of the reducer 17 via a coupling. The output end of the reducer 17 is meshed with the lower end of the rotating shaft 5 via the gear set 18. The driving gear is fixed to the output shaft of the reducer 17, and the driven gear is fixed to the lower end of the rotating shaft 5, thus realizing power transmission. The upper end of the rotating shaft 5 passes through the top of the drive box 3 and extends to the outside. A stirring drum 4 is located above the drive box 3, and the bottom of the stirring drum 4 is fixedly connected to the top of the drive box 3 with bolts.

[0027] like Figure 2 As shown, the inner wall of the mixing drum 4 is symmetrically provided with multiple sets of guide grooves 8 along the circumference. The guide grooves 8 are used to guide the flow of materials and change their movement path. The side wall of the rotating shaft 5 is provided with multiple sets of stirring blades 6 at intervals along the axial direction. Each set of stirring blades 6 includes two symmetrically distributed arc-shaped plates. The outer edge of the arc-shaped plates is in contact with the inner wall of the mixing drum 4, and the surface of the arc-shaped plates is provided with multiple protrusions. The cross-section of the protrusions is trapezoidal, and the top is provided with a wear-resistant coating to enhance the stirring effect and extend the service life. Two sets of elastic levers 7 are hinged to both sides of the rotating shaft 5. One end of the elastic lever 7 is connected to the rotating shaft 5 through a pin, and the other end slides in contact with the guide grooves 8 on the inner wall of the mixing drum 4. A torsion spring is provided in the middle of the elastic lever 7. One end of the torsion spring is fixedly connected to the elastic lever 7, and the other end is fixedly connected to the side wall of the rotating shaft 5 to provide elasticity compensation. In addition, a flexible scraper is provided on the outer edge of the elastic paddle 7. The flexible scraper is made of silicone and its thickness gradually decreases along the length of the elastic paddle 7. It is used to scrape off the material adhering to the inner wall of the mixing drum 4.

[0028] A feed inlet 9 is provided at the top of the mixing drum 4, and a sealing cover 10 is provided at the feed inlet 9. A locking ring is provided at the bottom of the sealing cover 10, and buckles are symmetrically provided on the outer side of the locking ring. The buckles are connected to the grooves at the top of the mixing drum 4 to fix the sealing cover 10. A handle is provided at the top of the sealing cover 10, and the two ends of the handle are fixedly connected to the sealing cover 10 by bolts. An anti-slip pad made of rubber is provided in the middle of the handle to facilitate the operator to open or close the sealing cover 10. A discharge pipe 11 is provided at the bottom of the mixing drum 4. One end of the discharge pipe 11 passes through the bottom of the mixing drum 4 and communicates with the inside of the mixing drum 4. A control valve 12 is provided at the other end.

One end of the adjusting rod is fixedly connected to the valve core of the control valve 12 to control the opening and closing of the discharge.

[0029] like Figure 2 As shown, a separation mechanism is installed inside the mixing drum 4. This mechanism includes multiple sets of separation plates 13, which are evenly distributed circumferentially along the inner wall of the mixing drum 4. The two ends of each separation plate 13 are slidably connected to the inner wall of the mixing drum 4 via slide rails. The slide rails have a T-shaped cross-section and are fixedly connected to the inner wall of the mixing drum 4 via screws. A lubrication groove is provided in the middle of the slide rail, filled with lubricating oil to reduce friction. A through hole is opened in the middle of each separation plate 13, and a filter screen 14 is embedded within the through hole. The filter screen 14 is made of stainless steel, and its aperture gradually increases along the height of the separation plate 13 to achieve graded processing of materials with different particle sizes. A return spring is installed at the bottom of each separation plate 13. One end of the return spring is fixedly connected to the separation plate 13, and the other end is fixedly connected to the inner wall of the mixing drum 4 to provide a reset function. One end of a set of push-pull rods 15 is hinged to the bottom of the separation plate 13, and the other end passes through the side wall of the mixing drum 4 and is fixedly connected to the external adjustment knob. The push-pull rods 15 and the side wall of the mixing drum 4 are sealed together by a sealing sleeve. Anti-slip texture is provided on the outer side wall of the adjustment knob. The cross section of the anti-slip texture is wavy and the depth gradually changes along the circumference of the adjustment knob, which makes it easy for the operator to adjust the position of the separation plate 13.

[0030] like Figure 3 As shown, the power transmission process of the transmission mechanism is as follows: After the motor 16 starts, its output shaft drives the input end of the reducer 17 to rotate through the coupling. The output end of the reducer 17 transmits power to the rotating shaft 5 through the gear set 18. The rotating shaft 5 rotates under the drive of the gear set 18, thereby driving the stirring blades 6 and the elastic pawl 7 to move synchronously. During the rotation, the stirring blades 6 perform preliminary mixing of the material, while the elastic pawl 7 slides in contact with the guide channel 8, generating additional disturbance and causing the material to form a complex flow path within the mixing drum 4. The separating plate 13 can move up and down within the mixing drum 4 through the adjustment of the push-pull rod 15, and the filter screen 14 is used to classify the mixed material.

[0031] In practical applications, the operator first opens the sealing cover 10 and adds the material to be mixed into the mixing drum 4 through the feed inlet 9. Then, the motor 16 is started, and the transmission mechanism drives the rotating shaft 5 to rotate. The stirring blades 6 and the elastic paddles 7 work together to efficiently mix the material. After mixing, the position of the separation plate 13 is adjusted by adjusting the knob, and the material is graded using the filter screen 14. Finally, the operator adjusts the opening degree of the control valve 12 by using the handwheel to discharge the mixed material from the discharge pipe 11. The entire process requires no additional power source, has a compact structure, is easy to operate, and can meet the material mixing and separation needs in different scenarios.

[0032] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of the compound mixing mixer is provided in conjunction with a specific application scenario.

[0033] In actual operation, the sealing cap 10 is first lifted by the handle, and the various compound materials to be mixed are added into the mixing drum 4 through the feed inlet 9. At this time, the locking ring at the bottom of the sealing cap 10 engages with the slot at the top of the mixing drum 4 to ensure the sealing of the feed inlet 9 and prevent the material from overflowing or becoming contaminated during the mixing process. Subsequently, the motor 16 is started, and the transmission mechanism begins to work. The output shaft of the motor 16 drives the reducer 17 to rotate through the coupling, and the output end of the reducer 17 drives the rotating shaft 5 to rotate through the gear set 18. The rotation of the rotating shaft 5 drives the stirring blades 6 and the elastic paddles 7 to move synchronously, thereby mixing the materials in the mixing drum 4.

[0034] During the mixing process, the outer edge of the arc-shaped plate of the stirring blade 6 is in contact with the inner wall of the stirring drum 4. The trapezoidal protrusions on its surface increase the contact area with the material, while the wear-resistant coating on top effectively reduces wear caused by long-term friction, extending the service life of the equipment. Furthermore, one end of the elastic paddle 7 is hinged to the rotating shaft 5 via a pin, and the other end slides in contact with the guide groove 8 on the inner wall of the stirring drum 4. Because the elastic paddle 7 has a torsion spring in the middle, the torsion spring provides elasticity compensation during rotation, ensuring that the elastic paddle 7 maintains good contact with the guide groove 8 at all times. This design not only scrapes off the material adhering to the inner wall of the stirring drum 4, but also changes the flow path of the material through the guiding effect of the guide groove 8, forming a complex turbulent effect, further improving the mixing efficiency.

[0035] After the materials are mixed, the operator can adjust the position of the separating plate 13 using the adjustment knob. One end of the push-pull rod 15 is hinged to the bottom of the separating plate 13, and the other end passes through the side wall of the mixing drum 4 and is fixedly connected to the external adjustment knob. During adjustment, the push-pull rod 15 drives the separating plate 13 to move up and down along the slide rail. The lubricating oil filled in the lubrication groove in the middle of the slide rail reduces sliding friction, ensuring smooth and stable movement of the separating plate 13. The filter screen 14 embedded in the middle of the separating plate 13 is made of stainless steel, and its pore size gradually increases along the height of the separating plate 13, thereby achieving graded processing of the mixed materials. The return spring provides a reset function when the separating plate 13 moves, ensuring that the separating plate 13 can return to its initial position without external force.

[0036] Finally, the operator adjusts the opening degree of the control valve 12 using a handwheel. The center of the handwheel is fixedly connected to the valve core of the control valve 12 via a threaded adjusting rod. Rotating the handwheel controls the opening and closing of the valve core, thereby adjusting the discharge speed of the discharge pipe 11. The mixed material is discharged from the discharge pipe 11, completing the entire mixing and separation process.

[0037] As can be seen from the above steps, this utility model utilizes the stable power transmission of the transmission mechanism, the synergistic effect of the stirring blades 6 and the elastic levers 7, and the grading function of the separation plate 13 to achieve efficient mixing and separation of materials. The reducer 17 and gear set 18 in the transmission mechanism effectively reduce the speed of the motor 16 while increasing the output torque, ensuring the stable operation of the stirring blades 6 and the elastic levers 7. The coordinated design of the elastic levers 7 and the guide channel 8 improves the mixing effect without adding an additional power source, while the adjustability of the separation plate 13 meets the grading requirements of materials with different particle sizes. The overall structure is compact and easy to operate, significantly improving production efficiency and reducing energy consumption.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
