Description

Technical Field

[0001] This utility model relates to the field of material dispersion technology, and in particular to a disperser with an independently lifting and lowering rotating shaft. Background Technology

[0002] Dispersers are widely used in various industries such as coatings, inks, and pigments. Their main function is to disperse and emulsify materials using a high-speed mixer, ensuring uniform mixing and improving production efficiency and product quality.

[0003] Currently, after dispersing materials, some material adheres to the surface of the dispersing disc, especially when dispersing materials with high viscosity. This requires manual scraping off, which is cumbersome. It is well known that a dispersing machine achieves better dispersion and higher efficiency if the rotating shaft can move up and down during the dispersion process. However, the rotating shaft of current dispersers can only move up and down via a lifting frame controller. The cover plate used to cover the dispersing tank is mounted on the lifting frame via a cylinder. If the lifting frame moves up and down, the cover plate also moves, which is inefficient and can easily damage the cylinder controlling the cover plate.

[0004] Based on this, this application provides a disperser with an independently lifting and lowering shaft to solve the above problems. Utility Model Content

[0005] This invention aims to solve the technical problems existing in the prior art. To this end, this invention provides a disperser with an independently movable shaft, which can use the centrifugal force generated by the shaft to throw off materials adhering to the dispersing disc, and can also control the up-and-down movement of the shaft during the dispersing process, thereby improving dispersing efficiency.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A disperser with an independently liftable shaft is provided, comprising a lifting frame, a splined sleeve rotatably disposed at the end of the lifting frame, a transmission device for driving the splined sleeve to rotate, a splined shaft inserted into the splined sleeve, a dispersing disc disposed at the bottom of the splined shaft, a bearing seat rotatably disposed at the top of the splined shaft, a lifting cylinder disposed on the lifting frame and connected to the bearing seat, and a retractable cover plate disposed at the bottom of the lifting frame for covering the dispersing tank; the top of the lifting frame is also provided with a limit switch via a bracket for limiting the position of the bearing seat, and the installation height of the limit switch is such that the dispersing disc is below the cover plate and above the liquid level in the dispersing tank.

[0007] In some optional embodiments, the top of the lifting frame is also provided with a limit switch via a bracket to limit the position of the bearing seat, and the installation height of the limit switch is such that the dispersing disc is below the cover plate and above the liquid level in the dispersing tank.

[0008] In some alternative implementations, the lifting cylinder is an electric cylinder, and there are two of them, which are respectively mounted on both sides of the lifting frame via mounting brackets.

[0009] In some alternative implementations, a PLC controller is also included, which is electrically connected to the limit switch, the lifting cylinder, and the transmission device.

[0010] In some optional embodiments, a sleeve fitted onto the spline shaft is also fixedly installed at the bottom of the spline sleeve. A rubber scraper with an inner ring matching the spline shaft is embedded at the bottom opening of the sleeve for scraping off the material adhering to the surface of the spline shaft, and the end of the sleeve away from the spline sleeve passes through the cover plate.

[0011] In some alternative embodiments, the rubber scraper is mounted on the sleeve via an end cap, the end cap being threadedly connected to the sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a lifting cylinder to control the up-and-down movement of the spline shaft, enabling the dispersing disc to reciprocate up and down during the dispersion process, effectively improving dispersion efficiency. Simultaneously, after dispersion, the dispersing disc can be positioned between the cover plate and the liquid surface inside the dispersing tank, and a transmission device can drive the spline shaft to rotate at high speed to fling off any material adhering to it, thus solving the problem of requiring manual scraping.

Example

[0019] As attached Figure 1 To be continued Figure 4As shown, this embodiment provides a disperser with an independently lifting shaft, including a lifting frame 1, a splined sleeve 2, a transmission device 3, a splined shaft 4, a dispersing disc 5, a bearing seat 6, a lifting cylinder 7, a cover plate 8, a cylinder 9, and a dispersing tank 10, wherein: The lifting frame 1 includes a hydraulic cylinder 1.1 and a box frame 1.2 located on top of the hydraulic cylinder. A splined shaft 2 is rotatably mounted on one end of the box frame, and the end of the splined shaft 2 located inside the box frame is connected to a transmission device 3. In this embodiment, belt drive is used, and the drive motor of the transmission device is located at the other end of the box frame. A splined shaft 4 passes through a splined sleeve 2, and the top of the splined shaft 4 passes through the box frame and connects to a bearing seat 6. Both ends of the bearing seat 6 are connected to lifting cylinders 7. Two lifting cylinders 7 are mounted on both sides of the box frame 1.2 through a mounting bracket. A dispersing disc 5 is detachably mounted on the bottom of the splined shaft 4. A cover plate 8 is fixedly mounted on the bottom of the box frame through multiple cylinders 9 to cover the dispersing barrel 10 and prevent material from spilling out during the dispersing process.

[0020] In practice, the dispersing barrel is moved directly below the dispersing disc, the lifting frame is controlled to descend so that the dispersing disc is at the bottom of the dispersing barrel, then the cylinder is controlled to press the cover plate against the dispersing barrel, and finally the transmission device is started to rotate the spline shaft to disperse the material. During the dispersion process, the lifting cylinder can be controlled to move up and down reciprocatingly. The stroke and reciprocating frequency can be adjusted according to the actual situation to effectively improve the dispersion efficiency.

[0021] In addition, this embodiment can also control the movement of the dispersing disc between the material and the cover plate, and use the transmission device to drive the spline shaft to rotate at high speed to throw off the material adhering to it, thereby solving the problem of needing to manually scrape the material.

[0022] To achieve accurate control of the dispersion disc's position, this embodiment further includes a limit switch 11 mounted on the top of the lifting frame 1 via a bracket, used to limit the position of the bearing seat 6. In this embodiment, the installation height of the limit switch 11 ensures that the dispersion disc 5 is below the cover plate 8 and above the liquid level within the dispersion tank 10. Preferably, the position of the limit switch 11 on the bracket is adjustable.

[0023] Preferably, in this embodiment, the lifting cylinder 7 is an electric cylinder, which can be controlled by a PLC controller. Specifically, after the material is dispersed, the PLC controller controls the lifting cylinder to lift until the limit switch detects a signal from the bearing housing, as shown in the attached diagram. Figure 5 As shown, the limit switch sends a signal to the PLC controller. The PLC controller then stops the lifting cylinder and starts the transmission device, causing the splined shaft to rotate at high speed, thus dislodging the material adhering to the dispersing disc. After a set running time, the transmission device stops. Finally, the cylinder can be controlled to retract, and the lifting frame can be controlled to rise. Example

[0024] Based on Example 1, as shown in the appendix Figure 1 Appendix Figure 4 and attached Figure 5 As shown, in this embodiment, a sleeve 12 fitted onto the spline shaft 4 is further fixedly installed at the bottom of the spline sleeve 2. A rubber scraper 13 with an inner ring matching the spline shaft is embedded at the bottom opening of the sleeve 12, used to scrape off material adhering to the surface of the spline shaft and prevent the adhering material from entering the spline sleeve. Preferably, the rubber scraper 13 is installed on the sleeve 12 via an end cap 14, which is threadedly connected to the sleeve 12.

[0025] Preferably, the end of the sleeve 12 away from the spline sleeve 2 passes through the cover plate 8, so that the scraped material enters the dispersion barrel.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
