Description

Technical Field

[0001] This utility model relates to the field of dispersing machine technology, and in particular to a splash-proof dispersing machine. Background Technology

[0002] A disperser is a commonly used piece of equipment in industrial production, primarily used to uniformly disperse solid particles into a liquid medium. It has wide applications in various fields such as coatings, inks, chemicals, and food. The core component of a disperser is a high-speed rotating dispersing disc, which uses shearing and centrifugal forces to break up solid particles and distribute them evenly in the liquid. Unlike mixers, dispersers not only achieve mixing but also effectively reduce particle agglomeration, improving dispersion efficiency.

[0003] Currently, during the operation of a disperser, some liquid remains on the dispersing disc after the mixing tank is removed. This residual liquid drips onto the ground or equipment surface, causing environmental pollution, increasing the cleaning burden, and potentially affecting the cleanliness and safety of the work area.

[0004] Therefore, we propose a splash-proof disperser. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a splash-proof disperser.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a splash-proof disperser, comprising a movable frame and an electrical control box fixedly installed on the movable frame, wherein a chain assembly is installed on the movable frame, and a first drive assembly is installed between the chain assembly and the movable frame, and a movable frame is fixedly connected to the chain assembly;

[0007] The top of the movable frame is fixedly connected to a top seat, and a main motor is fixedly installed on one side of the bottom of the top seat. The drive shaft of the main motor is fixedly connected to a dispersing shaft. A splash guard is rotatably sleeved on the outer surface of the dispersing shaft. An inverted cone cover is fixedly connected to the bottom of the splash guard, and the inverted cone cover seals the outer surface of the dispersing shaft.

[0008] A second drive assembly is fixedly installed on one side of the outer surface of the movable frame. The drive end of the second drive assembly is fixedly connected to a receiving plate, and a manual ball valve is fixedly connected to the bottom of the receiving plate.

[0009] Furthermore, the chain assembly includes two sprockets, which are arranged one above the other and rotatably connected to the movable frame. The two sprockets mesh together to engage the chain body, and one section of the chain body is fixedly connected to the movable frame. This chain drive structure makes the lifting and lowering operation of the movable frame more stable and reliable, and has a strong load-bearing capacity.

[0010] Furthermore, both the first and second drive components include a housing, which is fixedly connected to the movable frame. A drive motor is fixedly connected to one side of the outer surface of the housing. The drive shaft of the drive motor passes through the housing and is fixedly connected to a worm gear, which is rotatably connected to the housing. A worm wheel is meshed with the outer surface of the worm gear. One end of the worm wheel is fixedly connected to a rotating shaft, which passes through the housing and is rotatably connected to the housing. The top single sprocket is fixedly connected to the adjacent rotating shaft. The worm gear transmission method has a natural self-locking function and can stop stably at any position.

[0011] Furthermore, the receiving plate includes a movable plate, which is fixedly connected to an adjacent rotating shaft and a manual ball valve. A conical collection groove is provided on the top of the movable plate, and the conical collection groove is interconnected with the manual ball valve. The design of the conical collection groove can efficiently guide the dripping residual liquid to the center for collection.

[0012] Furthermore, the splash guard includes a cover body, which is sleeved on the outer surface of the dispersion shaft and fixedly connected to the top of the inverted cone cover. A bearing seat is fixedly embedded at the top center of the cover body, and the inner ring of the bearing inside the bearing seat is fixedly sleeved on the outer surface of the dispersion shaft. The bearing seat enables the splash guard to maintain a static seal, thus extending the equipment life.

[0013] Furthermore, the movable frame is slidably connected to the mobile frame, which provides guidance and constraint for the lifting and lowering of the movable frame, preventing it from deflecting or swaying during the lifting and lowering process.

[0014] The beneficial effects of this utility model are:

[0015] When in use, this utility model effectively prevents material splashing during operation through the splash guard and inverted cone cover, and automatically collects residual droplets after being lifted by the dispersion shaft through the movable receiving plate, and discharges them centrally through the bottom ball valve, completely solving the problems of residual liquid dripping polluting the environment and inconvenient cleaning, and significantly improving the cleanliness of the work area and the safety of operation.

Both ends of the sprocket 12 are provided with bearing seats, and the bearing seat body is fixedly connected to the mobile frame 1. The inner ring of the bearing inside the bearing seat is fixed to the mounting shaft of the sprocket 12.

[0026] A top seat 5 is fixedly connected to the top of the movable frame 11. A main motor 6 is fixedly installed on one side of the bottom of the top seat 5. A dispersion shaft 8 is fixedly connected to the drive shaft of the main motor 6. A splash guard is rotatably sleeved on the outer surface of the dispersion shaft 8. An inverted cone cover 14 is fixedly connected to the bottom of the splash guard. The inverted cone cover 14 is sealed and sleeved on the outer surface of the dispersion shaft 8. The splash guard includes a cover body 7, which is sleeved on the outer surface of the dispersion shaft 8 and fixedly connected to the top of the inverted cone cover 14. A bearing seat 15 is fixedly embedded at the top center of the cover body 7. The inner ring of the bearing inside the bearing seat 15 is fixedly sleeved on the outer surface of the dispersion shaft 8. The inverted cone cover 14 and the dispersion shaft 8 are sealed by a sealing sleeve. The sealing sleeve is sleeved on the outer surface of the dispersion shaft 8 and fixed to the inverted cone cover 14.

[0027] A second drive assembly is fixedly installed on one side of the outer surface of the movable frame 11. A receiving plate is fixedly connected to the drive end of the second drive assembly. A manual ball valve 9 is fixedly connected to the bottom of the receiving plate. The receiving plate includes a movable plate 2, which is fixedly connected to the adjacent rotating shaft 17 and to the manual ball valve 9. A conical collection groove 3 is provided on the top of the movable plate 2, and the conical collection groove 3 is connected to the manual ball valve 9. The manual ball valve 9 allows the operator to manually open and close the valve for centralized control of the discharge of collected liquid.

[0028] Both the first drive assembly and the second drive assembly include a housing 4, and the housing 4 is fixedly connected to the movable frame 11. A drive motor 19 is fixedly connected to one side of the outer surface of the housing 4. The drive shaft of the drive motor 19 passes through the housing 4 and is fixedly connected to a worm gear 18. The worm gear 18 is rotatably connected to the housing 4. A worm wheel 16 is meshed with the outer surface of the worm gear 18. A rotating shaft 17 is fixedly connected to one end of the worm wheel 16. The rotating shaft 17 passes through the housing 4 and is rotatably connected to the housing 4. A single sprocket 12 at the top is fixedly connected to the adjacent rotating shaft 17.

[0029] The electrical control box 10 integrates electrical components such as circuit breakers, contactors, frequency converters, PLCs (programmable logic controllers) or relay circuits. The box door is equipped with start / stop buttons, an emergency stop switch, a lifting control switch, and a touchscreen / indicator light. The electrical control box 10 is electrically connected to the main motor 6 and the drive motor 19, providing centralized control of the entire equipment's operation (start / stop and speed adjustment of the main motor 6, and control of the drive motor 19). It offers overload and short-circuit protection, ensuring operational safety and convenient human-machine interaction.

[0030] Working principle: First, the bucket containing the material is moved to a suitable position. Then, the drive motor 15 in the first drive assembly starts, driving the worm gear 18 to rotate, which in turn drives the meshing worm wheel 16 and the rotating shaft 17 to rotate, thereby driving the top sprocket 12 to rotate, ultimately causing the chain body 13 to move. Since a section of the chain body 13 is fixedly connected to the movable frame 11, the movement of the chain is converted into the overall descent of the movable frame 11, allowing the dispersing shaft 8 to stop at the required height. At this time, the cover plate body 7 is sealed and fitted against the top of the bucket.

[0031] The main motor 6 starts, driving the dispersing shaft 8 and the dispersing disc at its end to rotate at high speed, shearing and dispersing the material inside the barrel. During this process, the generated droplets will splash upwards. The equipment effectively prevents splashing through the sealing and protective structure of the splash guard. After the splashing droplets hit the inner inclined surface of the inverted cone shroud 14, their kinetic energy is absorbed, and they flow back into the barrel along the inclined surface under the action of gravity, thus preventing the material from splashing out of the barrel and ensuring a clean working environment.

[0032] After completing a batch of dispersion operations, the operator lifts the movable frame 11 and the dispersion shaft 8 using the first drive assembly. At this time, residual liquid adhering to the surfaces of the dispersion disc and the inverted cone shroud 14 will drip downwards due to gravity. To ensure that these drips do not contaminate the ground, after the dispersion shaft 8 rises to a certain height, the second drive assembly (whose structure is similar to the first drive assembly, including a housing 4, a drive motor 19, a worm gear 18, a worm wheel 16, and a rotating shaft 17) is activated, driving the movable disc 2 to rotate, moving it and positioning it directly below the dispersion shaft 8. The dripping liquid is effectively collected and temporarily stored by the conical collection trough 3 at the top of the movable disc 2.

[0033] Every so often or after collection is complete, the operator can open the manual ball valve 9 installed at the bottom of the movable plate 2 to discharge the collected residual liquid into a designated container for recycling or cleaning.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
