Description

Technical Field

[0001] This invention relates to the field of mixer technology, and in particular to a feeding device for a mixer equipped with an energy-saving electric motor. Background Technology

[0002] In many fields such as construction, chemical production, and food processing, mixers are widely used as core equipment for material mixing and processing. The working efficiency of their feeding devices, material processing effect, and energy consumption level directly affect the overall production quality and operating cost of the mixer.

[0003] Currently, most conventional mixer feeding devices on the market are simple funnel-type or straight-pipe-type structures, which can only achieve direct material conveying and lack material pretreatment functions. In actual production, the materials to be mixed often have agglomeration and uneven particle size. Unrefined materials entering the mixer chamber directly will not only increase the mixing load of the mixer, resulting in poor material mixing uniformity and prolonged mixing time, but also easily cause material jamming and blockage inside the mixer, affecting the normal operation of the equipment and reducing production efficiency.

[0004] Meanwhile, the drive motors of existing feeding devices are mostly ordinary electric motors, which have high energy consumption. During long-term continuous feeding operations, the power consumption is large, which does not meet the current development requirements of energy conservation, emission reduction, and green environmental protection in industrial production. In addition, the conveying structure of traditional feeding devices is mostly a fixed design, which can only achieve material conveying at a single rate. It cannot flexibly adjust the conveying mode according to the actual mixing conditions of the mixer and the material processing volume, resulting in poor adaptability. Some feeding devices also have inconvenient disassembly and maintenance of conveying components, and repairs are time-consuming and labor-intensive when equipment fails, further affecting the continuity of production.

[0005] Furthermore, in some feeding devices with simple grinding structures, the grinding components are mostly fixedly installed, resulting in a limited range of contact and grinding with the material, poor refining effect, and insufficient wear resistance of the grinding components. After long-term use, they are prone to wear and deformation, reducing the service life of the equipment.

[0006] In summary, existing mixer feeding devices suffer from numerous drawbacks, including poor material pretreatment, high energy consumption, limited conveying modes, low adaptability, and inconvenient maintenance. These shortcomings make it difficult to meet the demands of modern industrial production for efficient, energy-saving, convenient, and highly adaptable feeding operations. Therefore, developing a mixer feeding device with material refining capabilities, energy-saving drive components, and flexible adjustable conveying modes has become an urgent technical challenge for the industry.

[0014] Preferably, the outer surface of the grinding roller is provided with wear-resistant protrusions, which are made of rubber or metal.

[0015] Preferably, the first motor is an energy-saving motor.

[0016] Preferably, the second motor is an energy-saving motor.

[0017] The beneficial effects of the present invention are: (1) Equipped with an energy-saving motor, reducing energy consumption and environmental protection and lowering the cost of use: The first motor and the second motor of the present invention are both energy-saving motors. Compared with traditional ordinary drive motors, they can significantly reduce the consumption of power resources while achieving the same driving effect, which is in line with the development trend of energy saving, energy consumption reduction and green environmental protection in industrial production; at the same time, the operating power cost of the equipment is reduced, and long-term use can significantly reduce the production input of enterprises.

[0018] (2) Excellent material refining effect, improving the quality of subsequent mixing operations: The device is equipped with an integrated refining component, which drives the refining chamber to reciprocate through the reciprocating component. It works with a fixed grinding roller to grind the material. The outer surface of the grinding roller is equipped with wear-resistant protrusions made of rubber or metal to increase the grinding contact area and friction, which can effectively break up agglomerated materials and grind large-diameter materials into a uniform fine-diameter state. The sieve holes at the bottom of the refining chamber can screen the ground material. Only materials that meet the particle size requirements can enter the feeding chamber through the connecting pipe, which improves the material mixing uniformity of the subsequent mixer from the source, while reducing the mixing load of the mixer, shortening the mixing time, and improving the overall production efficiency.

[0019] (3) Flexible and adjustable conveying mode to adapt to different mixing conditions: The feeding chamber is equipped with a conveying structure with upper and lower double conveying shafts. With the help of the displacement component, the working state of the upper conveying shaft can be flexibly adjusted: the clamping block is pushed out of the mounting plate slot by the pneumatic cylinder, and the upper conveying shaft can be moved by pulling the traction handle to realize the meshing or separation of the first gear and the second gear, thereby controlling the start and stop of the upper conveying shaft. Combined with the continuous conveying of the lower conveying shaft, two conveying speeds of single and double conveying shafts can be realized. The feeding rate can be flexibly adjusted according to the mixing amount of the mixer, the material characteristics and other different working conditions, and the adaptability is extremely strong.

[0020] (4) Reasonable structural design, high operational stability and smoothness: The bottom of the refining chamber is connected to the feed nozzle through rollers, which greatly reduces the frictional resistance during the reciprocating motion of the refining chamber. Combined with the elastic support of the T-shaped inner rod, outer tube and second spring of the telescopic component, the movement of the refining chamber is more stable and avoids jamming. The moving block of the conveying component is slidably connected to the moving chamber through the moving wheel, which ensures the smoothness when adjusting the displacement of the upper conveying shaft. All rotating parts are connected by bearings, which reduces mechanical wear, improves the overall operational stability of the device and reduces the failure rate.

[0021] (5) Easy disassembly and maintenance, ensuring production continuity: The displacement component adopts a snap-fit ​​fixing structure of clamping block and mounting plate slot. The clamping block can be quickly unlocked and locked by the pneumatic cylinder. The displacement adjustment and disassembly of the upper conveyor shaft can be completed without the need for additional tools. The components of the fine component are modularly hinged and fixedly connected. The grinding roller, roller and other vulnerable parts can be disassembled and replaced separately. The operation is simple and time-saving during inspection and maintenance. The equipment can be quickly restored to operation, effectively ensuring the continuity of production.

[0022] (6) The grinding components are highly wear-resistant, extending the service life of the equipment: The wear-resistant protrusions on the outer surface of the grinding roller are made of rubber or metal, which have excellent wear resistance and can effectively resist frictional loss during the grinding process, avoid rapid wear and deformation of the grinding roller, and extend the replacement cycle of the grinding roller; at the same time, the connection and transmission structure of each metal component of the device is scientifically designed, which reduces mechanical wear during operation, improves the overall structural durability of the device, and reduces the maintenance and replacement costs of the equipment.

[0023] (7) Dual discharge port design to meet diverse feeding needs: The upper and lower discharge ports are set on the right side of the feeding chamber and are separated by a partition. With the different conveying modes of the dual conveying shaft, single discharge port feeding or simultaneous feeding of dual discharge ports can be realized. It can be adapted to different models and different feeding structures of mixers, and can also meet the needs of rapid feeding of large batches of materials, further improving the practicality and applicability of the device.

The feed nozzle 1 has a funnel-shaped structure, and its bottom end is welded and fixedly connected to the top end of the connecting pipe 3, which facilitates the input of materials to be processed. Several rollers 4 are connected to both sides of the bottom surface inside the feed nozzle 1 through a bracket. The refining chamber 5 is movably connected to the rollers 4. The rollers 4 provide support for the reciprocating motion of the refining chamber 5 and reduce friction. The refining chamber 5 is a rectangular cavity with an open top, and several sieve holes 6 are arrayed on its bottom end.

A reciprocating component is connected between the refining chamber 5 and the feed nozzle 1. The reciprocating component provides power for the reciprocating movement of the refining chamber 5.

[0036] like Figures 1 to 9 As shown, the telescopic assembly 8 includes a T-shaped inner rod 81, an outer tube 82, and a second spring 83. The lower end of the T-shaped inner rod 81 is slidably connected to the inner cavity of the outer tube 82 to realize the telescopic adjustment of the rod body. The upper end of the T-shaped inner rod 81 is hinged to the outer wall of the top of the refining chamber 5. The lower end face of the T-shaped inner rod 81 is elastically connected to the bottom surface of the inner cavity of the outer tube 82, and the second spring 83 provides a restoring force for the T-shaped inner rod 81. The end of the outer tube 82 is hinged to the inner wall of the mounting block 7, so that the telescopic assembly 8 can be angled according to the movement of the refining chamber 5.

[0037] like Figures 1 to 9As shown, the reciprocating assembly includes an arc-shaped rack 12, a gear mounting rod 13, a broken tooth 14, a first motor 15, and a belt 16. The arc-shaped rack 12 is welded and fixedly connected to the middle of the right side face of the refining chamber 5, with the tooth surface of the arc-shaped rack 12 facing outward.

The gear mounting rod 13 provides mounting support for the broken tooth 14, and the first motor 15 provides power to the reciprocating assembly. The broken tooth 14 is movably connected to the gear mounting rod 13 through a bearing. The broken tooth 14 is a partially toothed gear structure. The broken tooth 14 meshes with the arc-shaped rack 12, and the rotation of the broken tooth 14 drives the arc-shaped rack 12 to perform reciprocating arc motion. The pulley on the output end of the first motor 15 is connected to the pulley on the input end of the broken tooth 14 through the belt 16, realizing the power transmission from the first motor 15 to the broken tooth 14. The belt 16 is a synchronous transmission belt to ensure the stability of the transmission.

[0038] like Figures 1 to 9 As shown, the conveying assembly includes an upper conveying shaft 24, a moving chamber 25, a moving block 26, a moving wheel 27, a first gear 28, and a displacement component. The conveying assembly is the core structure of the device for adjustable speed conveying, and its outer wall is also provided with spiral conveying blades. Moving chambers 25 are welded and fixedly connected to both sides of the upper end of the feed chamber 2. The moving chambers 25 are rectangular chambers that provide guidance for the displacement of the moving blocks 26. Moving blocks 26 are slidably arranged in each moving chamber 25. Moving wheels 27 are fixedly connected to the upper and lower ends of each moving block 26 via rotating shafts. 27 is slidably connected in the inner wall groove of the moving chamber 25 to reduce the displacement friction of the moving block 26; the moving blocks 26 are movably connected to the upper conveying shaft 24 through the bearing 20, and the moving blocks 26 provide movable support for the upper conveying shaft 24; the left end of the upper conveying shaft 24 is keyed and fixed with a first gear 28, which is aligned with the second gear 30 to realize the meshing and disengagement of the two; the displacement component is connected between the right moving chamber 25 and the right moving block 26, and the displacement component provides control and support for the displacement and fixation of the upper conveying shaft 24.

[0039] like Figures 1 to 9As shown, the displacement assembly includes a mounting plate 33, a pull-out chamber 34, a pull-out rod 35, a traction handle 36, a pneumatic cylinder 37, a push block 38, a fixing block 39, a movable rod 40, a limit block 41, a clamping block 42, a retaining ring 43, a first spring 44, and a connecting column 45. The upper and lower ends of the right-side movable chamber 25 are both welded and fixedly connected to the mounting plate 33. Pneumatic cylinders 37 are bolted to the outer surfaces of the mounting plate 33. A push block 38, a hard metal block, is welded and fixedly connected to the output end of the pneumatic cylinder 37, enabling the clamping block 42 to be pushed and unlocked. The right end of the right-side movable block 26 is fixedly connected to the pull-out chamber 34 via a welded connecting column 45. The pull-out chamber 34 is a hollow rectangular cavity. The right end of the pull-out chamber 34 is fixedly connected to the traction handle 36 via a welded pull-out rod 35, allowing the operator to manually pull the pull-out chamber 34. The pull-out chamber 34 is located within the cavity of the right-side movable block 26. Fixed blocks 39 are welded and fixedly connected to both the upper and lower ends of the part. A movable rod 40 is slidably connected between the fixed blocks 39 and the inner wall of the pull-out chamber 34. The fixed blocks 39 provide guidance for the sliding of the movable rod 40. A limiting block 41 is welded and fixedly connected to the inner end of the movable rod 40 to prevent the movable rod 40 from disengaging from the pull-out chamber 34. A clamping block 42 is welded and fixedly connected to the outer end of the movable rod 40.

A first spring 44 is covered and connected to the outer surface of the lower end of the movable rod 40. The two ends of the first spring 44 abut against the retaining ring 43 and the fixed blocks 39 respectively to provide a restoring elastic force for the movable rod 40 and realize the automatic clamping of the clamping block 42.

[0040] The grinding roller 11 has wear-resistant protrusions integrally formed on its outer surface. These protrusions are made of rubber or metal. Rubber protrusions are suitable for easily broken materials, while metal protrusions are suitable for hard materials. Both can increase the grinding contact area and friction. The first motor 15 is an energy-saving motor, and the second motor 17 is an energy-saving motor. Both energy-saving motors significantly reduce the energy consumption of the equipment while ensuring the driving effect, which meets the requirements of green production.

[0041] The usage state of this invention is as follows: First, connect the upper discharge port 21 and lower discharge port 22 of the device to the feed end of an external mixer. Then, turn on the power supply. Based on the actual mixing conditions of the mixer, adjust the working state of the upper conveyor shaft 24 using the displacement component: If low-speed feeding is required, the control cylinder 37 is not activated, the clamping block 42 is engaged in the slot of the mounting plate 33, the first gear 28 and the second gear 30 are separated, and only the lower conveyor shaft 23 conveys materials; if high-speed feeding is required, activate the cylinder 37, which pushes the pusher block 38 to push the clamping block 42, causing... The movable rod 40 retracts into the pull-out chamber 34, compressing the first spring 44. The locking block 42 disengages from the slot of the mounting plate 33. The operator pulls the traction handle 36 or connects the traction handle 36 to an external traction device. The pull-out rod 35 drives the pull-out chamber 34, the connecting column 45, and the moving block 26 to slide in the moving chamber 25 until the first gear 28 and the second gear 30 are fully engaged. Then, the pneumatic cylinder 37 is closed, and the first spring 44 returns to its original position, pushing the locking block 42 into the right end face of the mounting plate 33, thus completing the fixation of the upper conveyor shaft 24. At this time, the upper conveyor shaft 24 and the lower conveyor shaft 23 work synchronously.

[0042] In the material pretreatment stage, the material to be stirred is fed into the refining chamber 5 through the feed nozzle 1. The first motor 15 is started, and the first motor 15 drives the broken tooth 14 to rotate through the belt 16. The broken tooth 14 meshes with the arc-shaped rack 12, driving the refining chamber 5 to make a reciprocating arc motion on the roller 4. The telescopic component 8 extends and retracts and adjusts the angle with the movement of the refining chamber 5. The second spring 83 ensures the stability of the movement of the refining chamber 5. During the reciprocating motion of the refining chamber 5, the material inside moves relative to the fixed grinding roller 11. The wear-resistant protrusions on the outer surface of the grinding roller 11 grind and disperse the material. The agglomerated material is broken up, and the large-diameter material is ground to the preset fine particle size. The material that meets the particle size requirements falls into the connecting pipe 3 through the sieve hole 6 at the bottom of the refining chamber 5, and then enters the feed chamber 2 through the connecting pipe 3.

[0043] During the material conveying stage, the second motor 17 is started, which drives the rotating shaft 29 to rotate. The rotating shaft 29 drives the lower conveying shaft 23 to rotate through the meshing of the third gear 31 and the fourth gear 32. If the upper conveying shaft 24 is in working condition, the rotating shaft 29 will also drive the upper conveying shaft 24 to rotate synchronously through the meshing of the second gear 30 and the first gear 28. Part of the material entering the feeding chamber 2 enters the upper chamber where the upper conveying shaft 24 is located and is pushed by the upper conveying shaft 24 to the lower discharge port 22 for discharge. The other part enters the lower chamber where the lower conveying shaft 23 is located and is pushed by the lower conveying shaft 23 to the upper discharge port 21 for discharge. Finally, the material enters the external mixer to complete the mixing operation.

[0044] When the equipment is under maintenance, if it is necessary to replace the grinding roller 11, roller 4 and other vulnerable parts, the modular components of the refining component can be disassembled and replaced directly. If it is necessary to repair the conveying component, after unlocking the clamping block 42 by the pneumatic cylinder 37, the upper conveying shaft 24 can be pulled out from the feeding chamber 2 by pulling the traction handle 36. The operation is simple and does not require additional tools. The repair can be completed quickly and the equipment can be restored to operation.
