Description

Technical Field

[0001] This utility model relates to the field of dispersion equipment technology, and in particular to a coating disperser. Background Technology

[0002] In the production process of coatings, it is necessary to uniformly disperse solid particles such as powdered pigments and fillers into a liquid base. Traditional coating dispersers typically use a high-speed rotating dispersing disc within a fixed tank to shear and stir the material to achieve dispersion. However, this traditional structure has some inherent drawbacks: First, incompletely dispersed clumps or large particles are easily present in the material, which may not be completely broken up in a single dispersion process, affecting the fineness and quality stability of the final product; second, during the dispersion process, some lightweight powders are prone to splashing, causing waste and environmental pollution; third, when processing materials with different particle size requirements, traditional equipment often requires dispersion followed by an additional sieving step, resulting in a cumbersome and inefficient process. Utility Model Content

[0003] The technical problem to be solved by this utility model is: in order to overcome the problem that the existing equipment often needs to disperse the material first and then perform additional screening steps when processing materials with different particle size requirements, which is cumbersome and inefficient, a coating disperser is provided.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a coating disperser, including a frame, a lifting mechanism, a dispersing mechanism and a barrel, wherein the lifting mechanism is fixedly connected to the frame, the output end of the lifting mechanism is connected to the barrel through transmission, and the lifting mechanism is used to provide power for the movement of the barrel so as to adjust the position of the dispersing mechanism; The dispersion mechanism includes a cover plate, a dispersion drive component, a dispersion shaft, a first dispersion disc, a second dispersion disc, and a screening barrel. The cover plate is fixedly connected to the frame and is used to cover the top port of the barrel. The dispersion drive component is fixedly connected to the frame, and its output end is connected to the dispersion shaft for transmission. The dispersion drive component provides power for the rotation of the first and second dispersion discs. Both the first and second dispersion discs are mounted on the dispersion shaft, with the first dispersion disc positioned above the second dispersion disc. The screening barrel and cover plate are connected. The screening barrel has several screen holes. The first dispersion plate is located inside the screening barrel, and the second dispersion plate is located between the screening barrel and the barrel body. By setting up a screening barrel with screen holes and the first and second dispersion plates arranged inside and outside, the dispersion and screening are carried out simultaneously. The first dispersion plate performs primary dispersion and strong shearing on the material inside the screening barrel. Qualified and fine slurry enters the barrel body through the screen holes, while lumps or large particles are left in the screening barrel to be further broken up, ensuring the uniformity and fineness of the final output and effectively improving product quality.

[0005] To address the issue of how to achieve smooth, precise, and reliable lifting of the barrel to coordinate with the dispersing mechanism in completing the work cycle, the lifting mechanism further includes a lifting motor, a lead screw, and a connecting seat. The lifting motor is fixedly connected to the frame, the lead screw is rotatably connected to the frame, the output end of the lifting motor is driven by the lead screw, the connecting seat is threadedly connected to the lead screw, and the connecting seat is fixedly connected to the barrel.

[0006] To address the issues of further improving screening efficiency, preventing material blockage of the screen holes, and enhancing the shearing and mixing effect of materials within the dispersion barrel, the dispersion mechanism further includes a screening drive component. The screening drive component is fixedly connected to the frame, and its output end is connected to the screening barrel via a transmission connection. The screening barrel and the cover plate are rotatably connected. The screening drive component provides power for the rotation of the screening barrel.

[0007] To address the issue of improving the stability of the high-speed rotating dispersing shaft and dispersing disc within the screening drum and preventing the dispersion effect and equipment lifespan from being affected by the vibration of the long shaft cantilever, a further method is proposed: a support component is installed on the dispersing shaft, the support component is located inside the screening drum, and the support component and the inner wall of the screening drum are in rotational contact.

[0008] To address the issue of optimizing the structure of the screening barrel to allow materials to flow more smoothly and centrally to the screening area and improve screening efficiency, the screening barrel is further designed to include a confluence section and a screening section. The confluence section has a structure that tapers inward from top to bottom, and the screen holes are opened on the screening section. The bottom surface of the confluence section and the top surface of the screening section are fixedly connected.

[0009] To address the issue of how to conveniently and thoroughly discharge the well-dispersed coating from the container, a further improvement is made by installing a discharge pipe with a valve at the bottom of the container.

[0010] The beneficial effects of this utility model are as follows: The coating disperser provided by this utility model achieves simultaneous dispersion and screening by setting a screening barrel with sieve holes and a first dispersion disc and a second dispersion disc arranged inside and outside. The first dispersion disc performs primary dispersion and strong shearing on the material in the screening barrel. Qualified and fine slurry enters the barrel through the sieve holes, while lumps or large particles are left in the screening barrel to be further dispersed, ensuring the uniformity and fineness of the final output and effectively improving product quality.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] like Figure 1 This is a structural schematic diagram of the present invention. A coating disperser includes a frame 1, a lifting mechanism 2, a dispersing mechanism 3, and a barrel 4. The lifting mechanism 2 is fixedly connected to the frame 1, and the output end of the lifting mechanism 2 is connected to the barrel 4 via a transmission. The lifting mechanism 2 is used to provide power for the movement of the barrel 4, thereby adjusting the position of the dispersing mechanism 3. The dispersing mechanism 3 includes a cover plate 31, a dispersing drive component 32, a dispersing shaft 33, a first dispersing disc 34, a second dispersing disc 35, and a screening barrel 36. The cover plate 31 is fixedly connected to the frame 1 and is used to cover the top port of the barrel 4. The dispersing drive component 32 is fixedly connected to the frame 1, and the output end of the dispersing drive component 32 is connected to the dispersing shaft 33 for transmission. The dispersing drive component 32 is used to provide power for the rotation of the first dispersing disc 34 and the second dispersing disc 35. The first dispersing disc 34 and the second dispersing disc 35 are both mounted on the dispersing shaft 33, and the first dispersing disc 34 is located above the second dispersing disc 35. The bottom end of the dispersing shaft 33 passes through the screening barrel 36, and the dispersing shaft 33 and the screening barrel 36 are rotatably connected by bearings.

[0016] The further dispersing drive component 32 can be a dispersing motor, and the output shaft of the dispersing motor and the dispersing shaft 33 are connected by a gear structure or a belt drive structure. The dispersing drive component 32 can also be a dispersing hydraulic cylinder, and the output shaft of the dispersing hydraulic cylinder and the dispersing shaft 33 are connected by a linkage mechanism.

[0017] The screening barrel 36 is connected to the cover plate 31. The screening barrel 36 has several screen holes 363. The first dispersion plate 34 is located inside the screening barrel 36, and the second dispersion plate 35 is located between the screening barrel 36 and the barrel body 4. By setting the screening barrel 36 with screen holes 363 and the first dispersion plate 34 and the second dispersion plate 35 arranged inside and outside, the dispersion and screening are carried out simultaneously. The first dispersion plate 34 performs primary dispersion and strong shearing on the material inside the screening barrel 36. The qualified and fine slurry enters the barrel body 4 through the screen holes, while lumps or large particles are left in the screening barrel 36 to be further dispersed, ensuring the uniformity and fineness of the final output and effectively improving the product quality.

[0018] like Figure 1 As shown, the dispersing mechanism 3 also includes a screening drive component 37, which is fixedly connected to the frame 1. The output end of the screening drive component 37 is connected to the screening barrel 36 via a transmission. The screening barrel 36 is rotatably connected to the cover plate 31. The screening drive component 37 is used to provide power for the rotation of the screening barrel 36. By adding an independent screening drive component 37 to drive the screening barrel 36 to rotate, relative motion is generated between the screening barrel 36 and the first dispersing disc 34. This not only effectively avoids the clogging of the screen holes 363, but also forms a more complex flow field and shear force, thereby improving the material throughput and the uniformity of dispersion.

[0019] The further screening drive 37 can be a dispersed motor, and the output shaft of the screening motor and the screening barrel 36 are connected by a gear structure or a belt drive structure.

[0020] A support member 38 is installed on the dispersing shaft 33. The support member 38 is located inside the screening barrel 36, and the support member 38 is in rotatable contact with the inner wall of the screening barrel 36. By setting the support member 38 on the dispersing shaft 33 in rotatable contact with the inner wall of the screening barrel 36, an additional support point is provided for the dispersing shaft 33 and the screening barrel 36, which greatly enhances its rigidity and stability, reduces vibration and sway, makes the dispersing process more stable, and extends the service life of the equipment.

[0021] The support member 38 has a gap for material to pass through.

[0022] like Figure 1 As shown, the screening barrel 36 includes a confluence section 361 and a screening section 362. The confluence section 361 has a structure that tapers inward from top to bottom. Screen holes 363 are opened on the screening section 362. The bottom surface of the confluence section 361 and the top surface of the screening section 362 are fixedly connected. The upper part of the screening barrel 36 is designed as an inwardly tapering confluence section 361. The inclined surface guides the material to concentrate in the central screening section 362, which is conducive to the material passing through the screen holes 363 more efficiently under the action of centrifugal force, avoiding the accumulation of material in the corners of the barrel wall and improving the working efficiency of the equipment.

[0023] The bottom of the barrel 4 is equipped with a discharge pipe 41 with a valve, which realizes a closed and controllable discharge method, ensuring thorough discharge and facilitating connection to subsequent pipes or containers, thereby improving the continuity and automation of production, while reducing material leakage and waste.

[0024] like Figure 1 As shown, the lifting mechanism 2 includes a lifting motor 21, a lead screw 22, and a connecting seat 23. The lifting motor 21 is fixedly connected to the frame 1, the lead screw 22 is rotatably connected to the frame 1, the output end of the lifting motor 21 is connected to the lead screw 22, the connecting seat 23 is threadedly connected to the lead screw 22, and the connecting seat 23 is fixedly connected to the barrel 4. It can provide sufficient thrust and self-locking capability to ensure that the barrel is accurately positioned and runs smoothly during the lifting process, thus ensuring the reliability of the entire equipment.

[0025] Working process: The lifting mechanism 2 is activated, driving the connecting seat 23 and the barrel 4 to rise via the lead screw 22, so that the port of the barrel 4 approaches or contacts the cover plate 31; the coating raw material to be dispersed is put into the screening barrel 36 inside the barrel 4; the dispersion drive 32 is activated, driving the dispersion shaft 33, the first dispersion disc 34 and the second dispersion disc 35 to rotate at high speed; the first dispersion disc 34 performs strong shearing and primary dispersion on the material in the screening barrel 36, and the dispersed fine slurry is thrown out through the sieve holes 363 on the screening barrel 36 under the action of centrifugal force, entering the space between the screening barrel 36 and the barrel 4; at the same time, the second dispersion disc 35 performs secondary dispersion and stirring on the slurry in this area to ensure overall uniformity; materials that fail to pass through the sieve holes 363 are dispersed and stirred. The clumps in the sieve holes 363 remain inside the screening barrel 36 and are circulated and processed by the first dispersing disc 34. After most of the material has been dispersed, the lifting mechanism 2 reverses its action, driving the barrel 4 to descend. At this time, the screening barrel 36 and the small amount of clumps remaining inside are exposed, and the dispersing mechanism 3 can continue to work. The first dispersing disc 34 can concentrate on processing these clumps. After processing, the valve of the discharge pipe 41 at the bottom of the barrel 4 is opened to discharge the dispersed high-quality coating. If a screening drive component 37 is provided, it can drive the screening barrel 36 to rotate in the opposite or same direction relative to the dispersing shaft 33. This can further enhance screening efficiency, prevent clogging of the sieve holes 363, and subject the material to more complex shear forces, thereby improving the dispersion effect.

[0026] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
