Description
Technical Field
[0001] This utility model relates to the field of vibration table technology, and in particular to a horizontal drum mixer. Background Technology
[0002] In the field of horizontal drum mixers, existing equipment typically includes a motor, a drum, and a drum shaft assembly. The motor is mounted on a frame and drives the drum shaft to rotate via a transmission device, thereby causing the mixing blades inside the drum to mix the materials. However, existing horizontal drum mixers have some problems and shortcomings in practical applications.
[0003] First, the adhesion of materials at the end of the drum shaft is a common challenge: existing technologies can achieve material classification by adding filter plates, inner mesh cylinders and other structures inside the drum, but the complex structure significantly increases the adhesion area, and materials tend to accumulate at the end of the drum shaft under normal operating conditions.
[0004] Secondly, in some existing technical solutions, the design of the mixing blades often adopts a fixed angle or a unidirectional spiral structure, which results in mixing dead zones inside the drum. Especially when the material accumulates at the bottom, traditional mixing blades have difficulty effectively mixing the materials, which not only affects the cleanliness of the equipment, but also leads to a decrease in the mixing effect.
[0005] Furthermore, the support and stability of the rollers cannot be ignored. The existing roller support method (the rollers are connected to the frame in a rolling manner, and the frame is fixed on the ground) cannot effectively reduce the vibration and noise during equipment operation, which will reduce the service life of the equipment. In addition, the way the frame is fixed also affects the mixing effect of materials.
[0006] To overcome the above-mentioned shortcomings, the inventor invented a horizontal drum mixer. Utility Model Content
[0007] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a horizontal drum mixer that prevents materials from accumulating at the end of the drum shaft, eliminates the need for complex structures inside the drum, and allows the mixing blades to effectively mix materials when they accumulate at the bottom. Furthermore, the frame is no longer fixed to the ground, effectively reducing vibration and noise during operation and increasing the equipment's lifespan.
[0008] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0009] A horizontal drum mixer includes a motor, a drum, and a drum shaft. The motor is mounted on the upper surface of the frame, and the output end of the motor is coaxially connected to the drum shaft. The drum shaft is arranged along the central axis of the drum, and a bearing is sleeved on the outer surface of the drum shaft. The drum shaft can drive the inner ring of the bearing to rotate together, and the outer ring surface of the bearing is fixedly connected to the drum. Agitator blades are provided on the drum shaft, and an anti-adhesion plate is provided at the end of the drum shaft. The drum shaft is connected to the geometric center of the anti-adhesion plate. A feed inlet is provided on the upper surface of the drum, and a discharge outlet is provided on the lower surface of the drum.
[0010] As a further implementation, the anti-adhesion plate is perpendicular to the roller shaft.
[0011] As a further implementation, anti-adhesion protrusions are provided on the side of the anti-adhesion plate closest to the motor.
[0012] As a further implementation, there are two stirring blades, and the edges of the stirring blades are rounded.
[0013] As a further implementation, the bottom of the roller contacts the upper surface of the frame.
[0014] As a further implementation, a roller is provided on the upper surface of the frame away from the motor. The roller is tangent to the outer surface of the drum, and the roller and drum rotate in opposite directions when they come into contact with each other.
[0015] As a further implementation, the lower surface of the frame is connected to the upper end of the hydraulic damper.
[0016] As a further implementation, the lower end of the hydraulic damper is fixedly connected to the support leg.
[0017] As a further implementation, the bottom of the support leg is placed on the ground.
[0018] As a further implementation, the inner surface of the drum and the outer surface of the stirring blades are mirror polished.
[0019] The beneficial effects of this utility model are as follows:
[0020] (1) This utility model uses an anti-adhesion plate installed at the end of the drum shaft, which is perpendicular to the drum shaft. This design can effectively prevent the material from adhering and accumulating at the end of the drum shaft, keeping the surface of the drum shaft clean. It does not add complex structures inside the drum, avoids material residue at the end of the drum shaft and inside the drum, and allows the material to be fully mixed inside the drum, improving the mixing effect. The anti-adhesion plate is provided with anti-adhesion protrusions on the side near the motor. The anti-adhesion protrusions increase the friction between the material and the anti-adhesion plate, making it difficult for the material to adhere to the surface of the anti-adhesion plate, further preventing the material from accumulating at the end of the drum. When the material accumulates at the bottom, the stirring blades can effectively mix the material and keep the equipment clean. At the same time, the anti-adhesion protrusions can guide the material to flow in a specific direction, promoting the circulation and mixing of the material inside the drum and improving the mixing efficiency.
[0021] (2) This utility model connects the lower surface of the frame to the upper end of the hydraulic damper. The hydraulic damper is connected to the lower surface of the frame, which can effectively absorb and buffer the vibration generated during the operation of the equipment, reducing the impact of vibration on the equipment and the surrounding environment. By adjusting the damping force of the hydraulic damper, the degree of suppression of equipment vibration can be adaptively controlled according to different working conditions and material characteristics. The frame is no longer fixed on the ground, which can effectively reduce the vibration and noise during the operation of the equipment and increase the service life of the equipment.

[0028] Example 1
[0029] This embodiment provides a horizontal drum mixer, such as Figures 1-3 As shown, it includes a motor 1, a drum 2, and a drum shaft 3; the motor 1 is mounted on the upper surface of the frame 4 and is the power source of the entire horizontal drum mixer. Through its rotation, it outputs mechanical energy to drive the rotation of the drum shaft 3, thereby driving the rotation of the stirring blades 6 inside the drum 2, providing power for the mixing of materials.
[0030] The output end of motor 1 is coaxially connected to drum shaft 3. Drum shaft 3 is set along the central axis of drum 2. Bearing 5 is sleeved on the outer surface of drum shaft 3. Drum shaft 3 can drive the inner ring of bearing 5 to rotate together, and the outer ring surface of bearing 5 is fixedly connected to drum 2. This design allows drum shaft 3 to rotate freely inside drum 2, while reducing the friction between drum shaft 3 and drum 2, improving the operating efficiency and stability of the equipment, and extending the service life of components. Agitator blades 6 are set on drum shaft 3, and an anti-adhesion plate 7 is set at the end of drum shaft 3. Drum shaft 3 and anti-adhesion plate 7 are connected. The drum 2 is geometrically connected, with a feed inlet 8 on its upper surface and a discharge outlet 9 on its lower surface. The drum shaft 3 is a key component connecting the motor 1 and the mixing blades 6. The drum shaft 3 transmits the power output from the motor 1 to the mixing blades 6. Simultaneously, the drum shaft 3 serves as the mounting base for the mixing blades 6, supporting them to maintain the correct position and angle within the drum 2, ensuring that the mixing blades 6 can effectively stir and mix the materials. The drum 2 is the core component of the horizontal drum mixer. It is a horizontally placed hollow cylinder used to hold the materials to be mixed. The drum 2 provides a mixing space for the materials and serves as the mounting base for other components such as the bearings 5 and the mixing blades 6, ensuring the stability and integrity of the entire mixer.
[0031] The stirring blades 6 cut, tumble and push the material inside the drum 2, causing the material to flow and mix in a complex manner inside the drum 2, thereby achieving uniform mixing of the material.
[0032] The anti-adhesion plate 7 primarily prevents materials from adhering to and accumulating at the end of the drum shaft 3, keeping the surface of the drum shaft 3 clean and smooth, ensuring the normal rotation of the drum shaft 3 and the effective operation of the mixing blades 6. It also helps improve the mixing effect of the materials and the cleanliness of the equipment. The feed inlet 8 facilitates the rapid and uniform input of materials. The feed inlet 8 is also equipped with a sealing cap (not shown in the figure) to prevent materials from leaking outside the equipment during the mixing process, ensuring the sealing and hygiene of the mixing process.
[0033] The discharge port 9 is used to discharge the material from the drum 2 after mixing. Its position and structural design should ensure that the material can be discharged smoothly from the drum 2, avoiding blockage or residue at the discharge port 9, thereby improving production efficiency and equipment cleanliness. The discharge port 9 may be equipped with a control valve to control the material discharge volume and discharge time.
[0034] The anti-adhesion plate 7 is kept 1-3cm away from the end of the roller 2. The anti-adhesion plate 7 is perpendicular to the roller shaft 3. It can effectively prevent the material from adhering and accumulating at the end of the roller shaft 3, keep the surface of the roller shaft 3 clean, avoid material residue at the end of the roller shaft 3 and the roller 2, so that the material can be fully mixed in the roller 2, improve the mixing effect, and ensure the normal rotation of the roller shaft 3 and the effective operation of the stirring blades 6.
[0035] Anti-adhesion ridges 10 are provided on the side of the anti-adhesion plate 7 closest to the motor 1. The anti-adhesion ridges 10 increase the friction between the material and the anti-adhesion plate 7, making it difficult for the material to adhere to the surface of the anti-adhesion plate 7, further preventing the material from accumulating at the end of the drum 2 and maintaining the cleanliness of the equipment. The anti-adhesion ridges 10 can guide the material to flow in a specific direction, promoting the circulation and mixing of the material in the drum 2 and improving the mixing efficiency.
[0036] There are two mixing blades 6, with rounded edges. These two blades effectively cut and tumble the material, creating complex flow and mixing within the drum 2, thus improving mixing uniformity. The rounded edges of the mixing blades 6 reduce damage to the material during rotation, making them particularly suitable for mixing fragile or brittle materials. This design also helps reduce the wear rate of the blades themselves.
[0037] The bottom of the roller 2 contacts the upper surface of the frame 4. The frame 4 provides stable support for the roller 2, ensuring the smoothness of the roller 2 during rotation, reducing vibration and sway, and transferring the weight of the roller 2 and the force exerted by the material on the roller 2 to the frame 4, which then distributes it to the entire equipment foundation, ensuring the overall stability of the equipment.
[0038] The lower surface of the frame 4 is connected to the upper end of the hydraulic damper 12. The hydraulic damper 12 is connected to the lower surface of the frame 4 and can effectively absorb and buffer the vibration generated during the operation of the equipment, reduce the impact of vibration on the equipment and the surrounding environment. By adjusting the damping force of the hydraulic damper 12, the degree of suppression of equipment vibration can be adaptively controlled according to different working conditions and material characteristics, ensuring the stable operation of the equipment under various working conditions, improving the stability of the equipment, and reducing the resonance of the equipment.
[0039] The lower end of the hydraulic damper 12 is fixedly connected to the support leg 13, so that the weight and vibration energy of the equipment can be transferred to the ground through the hydraulic damper 12 and the support leg 13, further enhancing the overall stability and load-bearing capacity of the equipment.
[0040] The bottom of the support leg 13 is placed on the ground, providing a solid foundation support for the entire horizontal drum mixer and ensuring the stability and safety of the equipment during operation.
[0041] The inner surface of drum 2 and the outer surface of stirring blades 6 are mirror-polished. This mirror polishing process makes the inner surface of drum 2 and the outer surface of stirring blades 6 very smooth, reducing material residue and adhesion on the surface, facilitating equipment cleaning and maintenance, and meeting the hygiene requirements of the food and pharmaceutical industries. Reduced friction and wear: The smooth surface of drum 2 reduces the friction between the material and the inner wall of drum 2 and stirring blades 6, reducing material wear on the equipment, extending the equipment's service life, and also helping to improve material flowability and mixing efficiency.
[0042] If necessary for production, the output of motor 1 can be connected to the roller shaft 3 via a coupling (that is, the coupling connects the output of motor 1 and the roller shaft 3 respectively).
[0043] The operation process of this horizontal drum mixer is as follows:
[0044] (1) Material preparation: The materials to be mixed are prepared manually to ensure that the materials meet the process requirements.
[0045] (2) Material addition: The material is manually added into the roller 2 through the feed port to ensure the accuracy and safety of material addition.
[0046] (3) Equipment start-up: Manually start motor 1 to start the rotation of drum shaft 3. Before starting, check whether each part of the equipment is normal.
[0047] (4) Stirring time setting: The stirring time of the stirring blade 6 is set manually according to the material characteristics and mixing requirements.
[0048] (5) Equipment operation monitoring: During the operation of the equipment, it is necessary to monitor the operating status of the equipment, such as the current and voltage of motor 1, the speed of drum 2, and the temperature of bearing 5, to ensure that the equipment operates normally.
[0049] (6) Adjustment of stirring speed: According to the mixing effect and process requirements, the speed of stirring blade 6 can be adjusted manually to achieve the best mixing effect.
[0050] (7) Material discharge: After mixing, manually operate the control valve of the discharge port 9 to discharge the material from the drum 2.
[0051] (8) Equipment cleaning and maintenance: After the mixing operation is completed, the equipment is cleaned manually, including cleaning the inside of the drum 2, the mixing blades 6, the anti-adhesion plate 7, and checking and maintaining each part of the equipment, such as lubricating the bearing 5 and checking the wear of the anti-adhesion plate 7.
