Description

Technical Field

[0001] This invention relates to the field of pulping equipment technology, and in particular to a material dispersion structure applied to a pulping machine. Background Technology

[0002] In the field of slurry preparation, a pulping machine is typically used to mix powder with liquid (i.e., solvent) to form a slurry with high solids content and high viscosity. The pulping machine utilizes the high-speed rotation of the rotor to generate shear force between the rotor and stator, which fully disperses the liquid before it enters the mixing chamber and mixes thoroughly with the powder, thereby forming a high-concentration and high-viscosity slurry.

[0003] Chinese utility model patent CN218308332U discloses a dispersion device and a pulping machine. The dispersion device has a first shearing device and a second shearing device that rotate in tandem. The shearing embedding ring of the second shearing device is embedded in a receiving groove between the inner and outer shearing rings of the first shearing device. The inner and outer shearing rings of the first and second shearing devices each have a plurality of radial through holes. The shearing embedding ring has a communication gap with each of the inner and outer shearing rings. The radial through holes of the inner and outer shearing rings are sequentially connected through these gaps, ensuring that the liquid is in a flowing state. Under the rotational shearing action of the first and second shearing devices, the liquid is fully dispersed to improve the mixing degree of the slurry. To maximize the dispersion efficiency, the number, diameter, and arrangement of the radial through holes on the inner and outer shearing rings and the shearing embedding ring of this dispersion device are usually set to be consistent. This greatly increases the probability of overlapping and connecting radial through holes during high-speed rotor rotation, allowing the liquid to pass quickly through the overlapping and connecting radial holes, significantly improving the dispersion speed. When the rotor of the dispersing device rotates at high speed relative to the stator, noise is inevitably generated between the two. When holes of the same diameter overlap between the rotor and the stator, interference occurs, further amplifying the noise. The more holes of the same diameter overlap, the greater the interference and the greater the noise. Therefore, dispersing devices with the same number, diameter, and arrangement of radial through holes will generate a lot of noise during operation. The noise transmitted to the working environment will have a serious impact on the physical and mental health of the workers. Summary of the Invention

[0004] In response to the shortcomings of existing dispersion devices, the applicant provides a material dispersion structure for a pulping machine with a reasonable structure. This structure uses a cross-distribution of pore sizes to ensure dispersion effect while reducing the probability of overlapping pores of the same size, minimizing interference from pore overlap, reducing noise, and ensuring the physical and mental health of workers.

[0005] The technical solution adopted in this invention is as follows:

[0006] A material dispersion structure for a pulping machine includes a first dispersion component and a second dispersion component that rotate and cooperate, one of which is a stator and the other is a rotor; the first dispersion component is provided with at least one upper dispersion ring, and the second dispersion component is provided with at least one second dispersion ring, with the upper dispersion ring and the second dispersion ring arranged alternately; m sets of upper channel groups are symmetrically arranged on the upper dispersion ring of the first dispersion component along the center of the first dispersion component, each set of upper channel groups includes several upper dispersion channels with at least two different apertures, and the several upper dispersion channels in each set of upper channel groups are arranged in descending order of aperture in a clockwise or counterclockwise direction;

[0007] The second dispersion ring of the second dispersion component has n groups of second channels symmetrically arranged along the center of the second dispersion component. Each group of second channels contains several second dispersion channels with at least two different apertures. The several second dispersion channels in each group of second channels are arranged in a clockwise or counterclockwise direction according to the aperture from large to small.

[0008] As a further improvement to the above technical solution:

[0009] The first dispersing component is also provided with at least one lower dispersing ring. The upper dispersing ring and the lower dispersing ring are arranged symmetrically on the upper and lower sides of the first partition. The structure of the lower dispersing ring is the same as that of the upper dispersing ring. The lower dispersing ring is also symmetrically provided with m groups of lower channels along the center of the first dispersing component. Each group of lower channels contains several lower dispersing channels with at least two different apertures. The several lower dispersing channels in each group of lower channels are arranged in a clockwise or counterclockwise direction according to the aperture from large to small.

[0010] A second dispersion component is rotatably fitted on the upper and lower sides of the first dispersion component, with the lower dispersion ring and the second dispersion ring arranged alternately.

[0011] m≥1, n≥1, and n≠m.

[0012] n and m are not integer multiples of each other.

[0013] Each aperture of each upper channel group includes several identical upper dispersion channels; each aperture of each lower channel group includes several identical lower dispersion channels; each aperture of each second channel group includes several identical second dispersion channels.

[0014] The size and orientation of the upper distribution channels in each upper channel group are the same as the size and orientation of the lower distribution channels in each lower channel group.

[0015] The size and arrangement direction of the second dispersion channel in each second channel group are the same as the size and arrangement direction of the upper dispersion channel in each upper channel group / the lower dispersion channel in each lower channel group.

[0016] The number of channel groups set on the upper dispersion ring, lower dispersion ring, and second dispersion ring is inversely proportional to the number of dispersion channels contained in each channel group.

[0017] The upper dispersion channel, lower dispersion channel, and second dispersion channel are through-hole structures or groove structures; the hole structure is a straight or inclined elongated hole, round hole, or square hole; the groove structure is a straight groove, inclined groove, semi-circular groove, or square groove.

[0018] The first dispersing component is provided with a first annular groove, and the second dispersing component is provided with a second annular groove. The upper dispersing ring / lower dispersing ring is inserted into the second annular groove, and the second dispersing ring is inserted into the first annular groove.

[0019] The beneficial effects of this invention are as follows:

[0020] In this invention, both the first and second dispersion components employ a cross-distribution of aperture sizes in their dispersion channels. This ensures excellent dispersion while effectively reducing noise. Furthermore, the grouped circular array distribution of the dispersion channels guarantees the balance of the equipment during high-speed operation. By using a grouped, cross-distribution method for the dispersion channels of the first and second dispersion components, the number and probability of overlapping apertures of the same diameter are reduced during high-speed rotation of the rotor relative to the stator, minimizing interference caused by aperture overlap and further reducing noise. Moreover, since the number of channel groups in the first and second dispersion components are not equal or integer multiples of each other, the number and probability of overlapping apertures of the same diameter are further reduced during high-altitude relative rotation, further contributing to noise reduction. The grouped, cross-distribution method of the dispersion channels in the dispersion components significantly reduces equipment operating noise, greatly reducing noise transmitted to the working environment, improving working comfort, and ensuring the physical and mental health of workers.

[0031] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0032] like Figure 1 , Figure 2 As shown, the upper and lower parts of the first dispersing component 1 of the present invention are respectively rotatably fitted with second dispersing components 2, and the two second dispersing components 2 are arranged facing each other; both the first dispersing component 1 and the second dispersing component 2 are disc-shaped structures; the first dispersing component 1 and the second dispersing component 2 are arranged coaxially. One of the first dispersing component 1 and the second dispersing component 2 is a stator, fixedly connected to the housing of the pulping machine, and the other is a rotor, sleeved on the main shaft. The main shaft is connected to a drive mechanism and is driven to rotate at high speed by the drive mechanism (this part of the structure is not shown in the figure).

[0033] like Figure 1 As shown, the first dispersing component 1 includes a radially arranged first partition 11 and at least one axially arranged upper dispersing ring 12 and lower dispersing ring 14. In this embodiment, a vertical upper dispersing ring 12 and a lower dispersing ring 14 are symmetrically arranged on the upper and lower sides of the outer side of the first partition 11. The second dispersing component 2 includes a radially arranged second partition 21 and at least one axially arranged second dispersing ring 22. In this embodiment, two coaxial second dispersing rings 22 are vertically arranged on the upper or lower side of the outer side of the second partition 21, and a second annular groove 24 is formed between the two second dispersing rings 22. Figure 1 , Figure 3 , Figure 4 As shown, the upper dispersion ring 12 / lower dispersion ring 14 of the first dispersion component 1 and the second dispersion ring 22 of the second dispersion component 2 are arranged alternately, with the upper dispersion ring 12 / lower dispersion ring 14 inserted into the second ring groove 24. Figure 8As shown, in another embodiment, the first dispersing component 1 may be provided with two or more upper dispersing rings 12 / lower dispersing rings 14, and a first annular groove 16 is formed between two adjacent upper dispersing rings 12 / lower dispersing rings 14; the second dispersing component 2 is provided with a corresponding number of matching second dispersing rings 22 and second annular grooves 24, the upper dispersing rings 12 / lower dispersing rings 14 and the second dispersing rings 22 are arranged alternately, the upper dispersing rings 12 / lower dispersing rings 14 are inserted into the second annular grooves 24, and the second dispersing rings 22 are inserted into the first annular grooves 16.

[0034] like Figure 5 As shown, m groups of upper channel groups 13 are symmetrically arranged along the center of the first dispersion component 1 on the upper dispersion ring 12, where m ≥ 1. Each group of upper channel groups 13 contains several upper dispersion channels 131 with at least two different apertures. The several upper dispersion channels 131 in each group of upper channel groups 13 are arranged sequentially in clockwise or counterclockwise order from largest to smallest aperture. Each aperture of each group of upper channel groups 13 includes several identical upper dispersion channels 131. The fewer the number of upper channel groups 13 on the upper dispersion ring 12, the more upper dispersion channels 131 are contained in each group of upper channel groups 13, and the more different aperture types can be set in each group of upper channel groups 13; conversely, the more upper channel groups 13, the fewer the number of upper dispersion channels 131 contained in each group, and the fewer different aperture types can be set in each group. Figure 5 As shown, in this embodiment, each upper channel group 13 includes seven upper dispersing channels 131, each with a different aperture, distributed clockwise from largest to smallest (view from top). Figure 7 As shown, in another embodiment, each upper channel group 13 includes nine upper dispersive channels 131, which are distributed clockwise in descending order of aperture (view from top). Some aperture types include one upper dispersive channel 131, while some aperture types include two or more upper dispersive channels 131.

[0035] like Figure 5 , Figure 7 As shown, the structure of the lower dispersion ring 14 of the first dispersion component 1 is the same as that of the upper dispersion ring 12. The lower dispersion ring 14 is also symmetrically arranged with m groups of lower channels 15 along the center of the first dispersion component 1, where m ≥ 1. Each group of lower channels 15 contains several lower dispersion channels 151 with at least two different apertures. The several lower dispersion channels 151 in each group of lower channels 15 are arranged in a clockwise or counterclockwise direction according to the aperture from large to small. Each aperture of each group of lower channels 15 includes several identical lower dispersion channels 151. The number of lower dispersion channels 151 in each group of lower channels 15 is equal to the number of upper dispersion channels 131 in each group of upper channels 13. The size and arrangement direction of the lower dispersion channels 151 are the same as the size and arrangement direction of the upper dispersion channels 131.

[0036] like Figure 6 As shown, the second dispersion ring 22 of the second dispersion component 2 has n groups of second channels 23 symmetrically arranged along the center of the second dispersion component 2, where n ≥ 1; where n ≠ m, that is, the number of channel groups in the second dispersion component 2 is not equal to the number of channel groups in the first dispersion component 1; moreover, n and m are not integer multiples of each other, that is, n / m ≠ 1, 2, 3... (natural numbers). Each group of second channels 23 contains several second dispersion channels 231 with at least two different apertures. The several second dispersion channels 231 in each group of second channels 23 are arranged in descending order of aperture in a clockwise or counterclockwise direction, and the size arrangement direction of the second dispersion channels 231 is the same as the size arrangement direction of the upper dispersion channel 131 / lower dispersion channel 151. Each aperture of each group of second channels 23 includes several identical second dispersion channels 231. Similarly, the fewer the number of second channel groups 23 set on the second dispersion ring 22, the more second dispersion channels 231 are contained in each second channel group 23, and the more different aperture types can be set in each second channel group 23; conversely, the more second channel groups 23 there are, the fewer second dispersion channels 231 are contained in each group, and the fewer different aperture types can be set in each group. The number and aperture of the second dispersion channels 231 contained in each second channel group 23 can be the same as or different from the number and aperture of the upper dispersion channels 131 / lower dispersion channels 151 in each upper channel group 13 / lower channel group 15. For example Figure 6 As shown, in this embodiment, each group of second channels 23 includes nine second dispersive channels 231, each with a different aperture, distributed clockwise from largest to smallest aperture (top view). In other embodiments, some aperture types of each group of second channels 23 may include one second dispersive channel 231, while some aperture types may include two or more second dispersive channels 231.

[0037] The upper dispersion channel 131, the lower dispersion channel 151, and the second dispersion channel 231 can adopt a through hole structure, such as a straight or inclined oblong hole, a round hole, a square hole, etc., or a through groove structure, such as a straight groove, an inclined groove, a semi-circular groove, a square groove, etc.

[0038] Since larger apertures in the dispersion channels result in lower noise and smaller apertures in better dispersion, the dispersion channels of both the first dispersion component 1 and the second dispersion component 2 employ a staggered aperture distribution. This ensures optimal dispersion while effectively reducing noise. Furthermore, the circular array distribution of the dispersion channels ensures the balance of the equipment during high-speed operation. Figure 3 , Figure 4As shown, when the dispersion channels of the first dispersion component 1 and the second dispersion component 2 are grouped and have alternating aperture sizes, the number and probability of overlapping apertures of the same aperture size are reduced during high-speed rotation of the rotor relative to the stator. This reduces the interference caused by aperture overlap and further reduces noise. Furthermore, since the number of channel groups in the first dispersion component 1 and the second dispersion component 2 are not equal or integer multiples of each other, the number and probability of overlapping apertures of the same aperture size are further reduced during high-relative rotation, which further contributes to noise reduction. By using a grouped and alternating aperture size distribution method for the dispersion channels of the dispersion components, the operating noise of the equipment is significantly reduced, greatly reducing the noise transmitted to the working environment, improving the comfort of the working environment, and ensuring the physical and mental health of the workers.

[0039] The above description is an explanation of the present invention and not a limitation thereof. The present invention can be modified in any form without departing from its spirit.
