Description

Technical Field

[0001] This utility model relates to the technical field of kaolin processing equipment, and in particular to a kaolin rotary blade dispersing device. Background Technology

[0002] Kaolin, as an important non-metallic mineral resource, is used in many industrial fields such as papermaking, ceramics, and coatings. In its primary processing stage, the mined raw ore usually needs to be broken up and dispersed to facilitate subsequent purification and refining. Rotary blade type breaking and dispersing device is a commonly used equipment to achieve this process. It uses a motor to drive the stirring blades on the main shaft to rotate at high speed, which strongly impacts, shears, and stirs the kaolin material, thereby breaking up the clumps and dispersing it evenly in the medium.

[0003] Naturally mined kaolin ore is not a pure clay mineral; it contains hard impurities such as stones and gravel of various sizes. In existing dispersing devices, the mixing blades are usually rigidly fixed to a rotating drum or shaft. When the equipment is running at high speed, these hard stone impurities are rolled up along with the material and collide violently and frequently with the high-speed rotating mixing blades.

[0004] Because this connection method is rigid, the huge impact force generated by the collision will act directly on the stirring blades without any buffer. This repeated strong impact can easily cause the stirring blades to become fatigued, deformed, cracked, or even broken and destroyed. The damage to the blades will not only seriously affect the efficiency and uniformity of the dispersion, but also cause the equipment to need to be stopped frequently for maintenance and replacement, increasing production and maintenance costs, and reducing the operational reliability and overall production efficiency of the equipment.

[0005] Therefore, this utility model proposes a kaolin rotary blade dispersing device to address the shortcomings of existing technologies. Utility Model Content

[0006] In view of the problems in the existing technology of kaolin rotary blade dispersing device, the mixing blades and the drum are rigidly connected, which makes them prone to breakage and damage due to hard collision when processing materials containing impurities such as stones. In addition, there is no effective separation mechanism for stone impurities, resulting in low equipment reliability and high maintenance costs. The present invention aims to provide a kaolin rotary blade dispersing device with improved structure that can effectively solve the above problems and has dual protection function.

[0007] This utility model provides a kaolin rotary blade dispersing device, including: a mixing chamber, a rotating shaft disposed in the mixing chamber and a drum fixedly connected to the rotating shaft; and mixing blades disposed on the drum, a separating mechanism fixed in the mixing chamber and a buffer mechanism for mounting the mixing blades.

[0008] The separating mechanism consists of a first arc-shaped plate and a second arc-shaped plate, both of which have filter holes for screening materials. The buffer mechanism includes a fixed chamber, a second fixed shaft, and a torsion spring installed in the fixed chamber. The stirring blades have through holes.

[0009] Furthermore, the partition mechanism is fixedly installed on the lower part of the inner wall of the mixing chamber, forming a surrounding structure below the drum; the mixing blades are connected to the drum through a buffer mechanism. Specifically, the fixed chamber of the buffer mechanism is fixed on the outer wall of the drum, the second fixed shaft passes through the through hole on the mixing blade, and the mixing blade is rotatably connected to the inside of the fixed chamber, while the torsion spring is set in the fixed chamber and elastically abuts against both sides of the mixing blade, forming an elastic and deflectable connection structure.

[0010] Preferably, in order to effectively discharge the sieved stones, the separating mechanism further includes a first fixed shaft and a baffle. The first fixed shaft is arranged horizontally, and the baffle is rotatably connected to the first fixed shaft. The position of the baffle is exactly in the gap between the bottom of the first arc-shaped plate and the second arc-shaped plate, which is used to pull out the stones that fall into this gap.

[0011] Preferably, in order to achieve stable installation and convenient disassembly of the separation mechanism, a groove is provided on the inner wall of the mixing chamber. The upper section of the first arc-shaped plate is fastened to the groove with screws, and its lower section is fixed to the mixing chamber with screws. The bottom of the second arc-shaped plate is also fixed to the bottom of the mixing chamber with screws. This screw connection method facilitates the disassembly, cleaning or replacement of the first and second arc-shaped plates.

[0012] Preferably, to further improve the stability of the separating mechanism against stone impact, a rubber sleeve is added between the upper section of the first arc-shaped plate and the groove. The rubber sleeve fills the space between the two when it is tightened, which can effectively absorb and buffer the vibration generated when the stone hits the first arc-shaped plate, and prevent the connecting screws from loosening due to long-term vibration.

[0013] Preferably, to improve the cleanliness and operational reliability of the internal structure of the buffer mechanism, the fixed chamber is provided with an opening, and the buffer mechanism also includes a flexible plate. The flexible plate is fixed at the opening of the fixed chamber to provide a shielding and sealing function, which can effectively prevent kaolin mud or impurities from entering the fixed chamber and avoid affecting the normal operation of the torsion spring.

[0014] Preferably, in order to clarify the spatial relationship between the separating mechanism and the drum to achieve the best screening and blocking effect, the separating mechanism is disposed entirely below the outer periphery of the drum, and the inner arc surfaces of the first arc plate and the second arc plate face the drum, forming an arc-shaped channel concentric with the drum.

[0015] Preferably, as a specific buffer implementation, the number of torsion springs is two. These two torsion springs are symmetrically arranged on both sides of the stirring blade located inside the fixed chamber structure, which can provide uniform and stable elastic support and restoring force to the stirring blade from two directions.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problem in the prior art that stones in kaolin raw materials are rolled up and frequently collide with the stirring blades during the stirring process by setting a separation mechanism composed of a first arc-shaped plate with filter holes and a second arc-shaped plate. It achieves the technical effect of pre-screening and blocking large stones, reducing the number of times the blades are impacted from the source, thereby effectively protecting the stirring blades.

[0018] 2. This utility model, by setting a buffer mechanism, enables the stirring blade to achieve elastic rotational connection with the drum through the second fixed shaft and torsion spring. This solves the problem in the prior art where the impact force directly acts on the stirring blade when it collides rigidly with the stone, causing it to be prone to breakage or damage. It achieves the technical effect of converting rigid impact into elastic buffer, effectively absorbing and unloading impact energy, thereby preventing the stirring blade from breaking and significantly improving the reliability and service life of the equipment.

[0019] 3. This utility model, through the dual protective synergy of the separation mechanism and the buffer mechanism, and supplemented by the rubber sleeve for shock absorption and the flexible plate for dust prevention, solves the problems of the existing mixing device having a simple structure, poor adaptability to materials containing impurities, unstable overall operation and easy damage. It achieves the technical effect of reasonable structural design, comprehensive protection measures, high overall machine operation stability, and long-term and efficient processing of kaolin containing stones.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 4 This utility model provides a kaolin rotary blade dispersion device, which aims to solve the problem in the prior art that stone impurities during kaolin mixing can easily cause rigid collisions and damage to the mixing blades 5.

[0029] like Figure 1 As shown, the kaolin rotary blade dispersing device includes a mixing chamber 1 and a rotating shaft 2 rotatably disposed within the mixing chamber 1. A roller 3 is fixedly connected to the rotating shaft 2. The device also includes a partitioning mechanism 4 fixed to the lower part of the inner wall of the mixing chamber 1, such as... Figure 2 and Figure 3 As shown, the separating mechanism 4 includes a first arc-shaped plate 401 and a second arc-shaped plate 402, both of which have filter holes 403. Figure 1 and Figure 4 As shown, the device also includes a buffer mechanism 6 and a stirring blade 5 mounted on the drum 3 via the buffer mechanism 6. The buffer mechanism 6 includes a fixed chamber 601 fixed on the drum 3. A second fixed shaft 602 is rotatably disposed in the fixed chamber 601. A through hole 605 is provided on the stirring blade 5. The second fixed shaft 602 passes through the through hole 605 to rotatably connect the stirring blade 5 to the fixed chamber 601. The buffer mechanism 6 also includes a torsion spring 603 disposed in the fixed chamber 601 and elastically abutting against both sides of the stirring blade 5.

[0030] Please refer to Figure 2 and Figure 3The structure of the separating mechanism 4 is described in detail below. The separating mechanism 4 includes a first arc-shaped plate 401 and a second arc-shaped plate 402. Both the first arc-shaped plate 401 and the second arc-shaped plate 402 have filter holes 403. A groove 408 is formed on the mixing chamber 1. The upper section of the first arc-shaped plate 401 is fixed to the groove 408 by screws 406. A rubber sleeve 407 is also fixed between the upper section of the first arc-shaped plate 401 and the groove 408. The rubber sleeve 407 is used to absorb the vibration generated by the impact of stones. The lower section of the first arc-shaped plate 401 is also fixed to the mixing chamber 1 by screws 406. The bottom of the second arc-shaped plate 402 is fixed to the bottom of the mixing chamber 1 by screws 406. The separating mechanism 4 also includes a first fixed shaft 404 and a baffle 405 rotatably connected to the first fixed shaft 404. The baffle 405 is disposed in the gap between the bottoms of the first arc-shaped plate 401 and the second arc-shaped plate 402. Figure 1 As shown, the separating mechanism 4 is located below the outer periphery of the roller 3, and the inner arc surfaces of the first arc plate 401 and the second arc plate 402 face the roller 3.

[0031] Please refer to Figure 4 The structure of the buffer mechanism 6 is further described in detail. The fixed chamber 601 is provided with an opening. The buffer mechanism 6 also includes a flexible plate 604 fixed at the opening of the fixed chamber 601. The flexible plate 604 is used to prevent soil from entering the interior of the fixed chamber 601. As a preferred embodiment, there are two torsion springs 603, which are respectively provided on both sides of the stirring blade 5 located inside the fixed chamber 601. The two torsion springs 603 elastically abut against the stirring blade 5.

[0032] Working principle: In mixing chamber 1, the kaolin is rotated by the roller 3 on the rotating shaft 2. Smaller stones are sieved through the filter holes 403 on the first and second arc-shaped plates 401 and 402 in the separating mechanism 4, allowing the kaolin to pass through without affecting the mixing. Larger stones, under the combined action of rotation and their own weight, are guided by the arc surfaces of the first and second arc-shaped plates 401 and 402 to roll into the gap between their bottoms. Then, the rotation of the baffle 405 on the first fixed shaft 404 causes the stones to fall to the bottom. When the stones are about to be lifted by the force generated by rotation, the first and second arc-shaped plates 401 and 402 prevent larger stones from damaging the mixing blades 5. The gap between the first and second arc-shaped plates 401 and 402... The force applied to the roller 3 is along the circumferential tangent direction. Guided by the baffle 405, it will not be rolled up. At the same time, the upper part of the first arc plate 401 is fixed to the groove 408 opened on the mixing chamber 1 by screws 406. A rubber sleeve 407 is fixed between the first arc plate 401 and the groove 408 to absorb the vibration generated by the impact of stones on the first arc plate 401 and prevent it from falling off after long-term use. The lower part of the first arc plate 401 is fixed to the mixing chamber 1 by screws 406 to realize the disassembly of the first arc plate 401 and thus clean the stones. The bottom of the second arc plate 402 is also fixed to the bottom of the mixing chamber 1 by screws 406 to realize its disassembly and cleaning, to screen and block the stones, and to prevent the stones from being rolled up and colliding with the mixing blades 5 during the mixing process, which would cause deformation and damage to the mixing blades 5 and affect the mixing efficiency.

[0033] Furthermore, a fixed chamber 601 of the buffer mechanism 6 is fixed on the drum 3. The second fixed shaft 602 passes through the through hole 605 on the stirring blade 5 to fix the stirring blade 5 to the fixed chamber 601. Torsion springs 603 provide elastic support for the stirring blade 5 on both sides, changing the rigid connection between the bottom of the stirring blade 5 and the drum 3 into a sliding connection. When the stirring blade 5 is impacted during rotation, the torsion springs 603 buffer it, allowing the stirring blade 5 to rotate on the second fixed shaft 602, preventing the stirring blade 5 from breaking due to strong impact. At the same time, a flexible plate 604 is fixed at the opening of the fixed chamber 601 to prevent soil from entering and affecting the torsion springs 603 without affecting the rotation of the stirring blade 5. Through the elastic support of the stirring blade 5, the impact force is prevented from being directly transmitted to the drum 3 after the stirring blade 5 is impacted, thus preventing the stirring blade 5 from breaking.
