Description

Technical Field

[0001] The utility model relates to the technical field of slurry dispersion, in particular to a dispersion mechanism. Background Art

[0002] In the lithium battery pulping process, the powder and slurry are transported to the pulping machine for mixing to obtain the slurry. The more uniform the slurry is dispersed, the better the performance of the prepared lithium battery. Therefore, a dispersion mechanism will be added in the transformation of old equipment used to produce batteries. The dispersion mechanism is used to shear and disperse the slurry during the transportation process. At present, when the dispersion mechanism is introduced, it is necessary to configure a delivery pump (such as a screw pump, a rotor pump, etc.) outside the dispersion mechanism to make the slurry pass through the dispersion mechanism, making the structure of the equipment look more complicated. Specifically, in order to achieve efficient dispersion, the existing dispersion mechanism usually sets a plurality of levels of stators and rotors in the device to cooperate with each other to grade and disperse the slurry. Although such a dispersion mechanism can achieve efficient dispersion of the slurry, due to the long distance, large flow resistance, low fluidity, and large flow loss, it is generally only used for the transportation of slurry with small flow and low viscosity, or the power of the delivery pump needs to be increased. However, it cannot meet the requirements for slurry transportation with large flow rate and high viscosity. In order to reduce flow resistance, improve fluidity and reduce flow loss to meet the requirements of slurry transportation with large flow rate and high viscosity, some slurry dispersion mechanisms usually reduce the number of stators and rotors inside the dispersion mechanism, or simplify the dispersion mechanism. This will lead to the problem of insufficient slurry dispersion, resulting in poor slurry dispersion effect. Utility Model Content

[0003] The utility model aims to provide a dispersing mechanism, which mainly solves the technical problem of how to improve the dispersing effect of slurry with large flow rate and high viscosity.

[0004] To achieve this purpose, the utility model adopts the following technical solutions:

[0005] A dispersion mechanism comprises a housing, a first dispersion component, a second dispersion component and an impeller;

[0006] The housing has a chamber therein, and the chamber includes a first dispersion chamber and a second dispersion chamber that are connected to each other;

[0007] The first dispersion assembly includes a plurality of stators and a plurality of rotors disposed in the first dispersion chamber, wherein the plurality of stators are fixedly connected to the housing, and the plurality of rotors are rotatably connected to the housing, and the rotors rotate relative to the stators to shear and disperse the slurry together with the stators;

[0008] The second dispersing assembly comprises a rotating blade disc and a baffle plate both disposed in the second dispersing chamber, the baffle plate being fixedly connected to the housing, the rotating blade disc being rotatably connected to the housing, and the rotating blade disc rotating relative to the baffle plate to shear and disperse the slurry together with the baffle plate;

[0009] The impeller is disposed in the chamber and located between the first dispersion component and the second dispersion component. The impeller is rotatably connected to the shell and is used to drive the slurry flowing out of the first dispersion chamber to flow into the second dispersion chamber and then be discharged to the outside.

[0010] In one of the technical solutions, the first dispersion chamber is arranged above the second dispersion chamber, so that the slurry in the first dispersion chamber can flow toward the second dispersion chamber spontaneously due to its own weight.

[0011] In one of the technical solutions, the stator is provided with a first shearing portion, the rotor is provided with a second shearing portion, a plurality of the stators are arranged in sequence and a first gap is provided between each adjacent two of the first shearing portions, a plurality of the rotors are arranged in sequence and a second gap is provided between each adjacent two of the second shearing portions, the second shearing portion is provided in each of the first gaps, and the first shearing portion is provided in each of the second gaps.

[0012] In one of the technical solutions, a first shearing hole is provided on the first shearing portion, and a second shearing hole is provided on the second shearing portion.

[0013] In one of the technical solutions, the first shearing hole penetrates the stator along the axial direction of the stator, and the second shearing hole penetrates the rotor along the axial direction of the rotor.

[0014] In one of the technical solutions, the baffle includes a main body and two ribs protruding from the main body, an annular flow channel groove is arranged between the two ribs, the rotating cutter disc includes a connected base and an annular boss, the boss is embedded in the flow channel groove, a plurality of penetrating third shear holes are arranged on the two ribs, and a plurality of penetrating fourth shear holes are arranged on the boss.

[0015] In one of the technical solutions, when the rotating cutter disc rotates to any position relative to the baffle, the penetration direction of any of the third shearing holes and the penetration direction of any of the fourth shearing holes are not on the same straight line.

[0016] In one of the technical solutions, the impeller is fixedly connected to the base, and the boss is arranged around the outer circumference of the impeller.

[0017] In one of the technical solutions, the impeller has a self-priming characteristic, and the slurry in the first dispersion chamber tends to automatically flow to the second dispersion chamber due to the suction force of the rotation of the impeller.

[0018] In one of the technical solutions, the dispersion mechanism also includes a driving device, which includes a connected motor and a rotating shaft. The motor is fixedly connected to the shell and is located outside the chamber. The rotating shaft is rotatably connected to the shell and extends into the chamber and is sealed to the shell. The motor is used to drive the rotating shaft to rotate, and the plurality of rotors, the rotating cutter disc and the impeller are all connected to the rotating shaft.

[0019] Compared with the prior art, the dispersion mechanism provided by the utility model has at least the following beneficial effects:

[0020] This solution is provided with two dispersion components. When working, the slurry enters the first dispersion chamber of the shell, and the slurry is firstly dispersed strongly by the joint shearing of multiple stators and multiple rotors. The structure of using stators and rotors for slurry dispersion can also make the flow of slurry almost unaffected by centrifugal force, so that the slurry can be smoothly driven by the impeller in the middle position and enter the second dispersion chamber, and then the baffle and the rotating cutter disc are sheared together to achieve the second dispersion;

[0021] Compared with the traditional dispersion mechanism with only multi-stage stators and rotors, this scheme can reduce the number of stages used by the stators and rotors to shorten the distance of the slurry flowing on the rotors and stators, thereby solving the problem of large flow loss of slurry with high viscosity after shearing by all rotors and all stators. However, since this scheme also provides a second dispersion component using a baffle and a rotating cutter disc to cooperate with each other and an impeller to drive the slurry to be discharged, although the number of stages of the stators and rotors is reduced, the slurry discharged to the outside can also have a good dispersion effect, that is, this scheme is more suitable for dispersing slurries with large flow and high viscosity. After dispersion, the flow of the slurry will not be lost too much and can still have a better dispersion effect. Among them, the pumping function of the impeller can reduce the power of the external delivery pump and can even replace the external delivery pump to simplify the appearance structure of the equipment.

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] Please also read Figures 1 to 8 The present embodiment provides a dispersion mechanism, including a shell 1, a first dispersion component 2 and a second dispersion component 3, wherein a chamber 11 is arranged in the shell 1, and a feed port 12 and a discharge port 13 respectively connected to the chamber 11 are arranged on the shell 1, wherein the chamber 11 specifically includes a first dispersion chamber 111 and a second dispersion chamber 112 connected to each other, the feed port 12 is connected to the first dispersion chamber 111, and the discharge port 13 is connected to the second dispersion chamber 112, the slurry enters from the feed port 12 and passes through the first dispersion chamber 111 and the second dispersion chamber 112 in sequence, and then runs out from the discharge port 13 to the outside, the above-mentioned first dispersion component 2 is arranged in the first dispersion chamber 111 to disperse the slurry for the first time, and the above-mentioned second dispersion component 3 is arranged in the second dispersion chamber 112 to disperse the slurry for the second time.

[0039] Among them, the first dispersion component 2 specifically includes multiple stators 21 and multiple rotors 22, wherein the stator 21 is fixedly connected to the shell 1, and the rotor 22 can rotate relative to the stator 21. The rotor 22 rotates relative to the stator 21 to shear the slurry together with the stator 21 to achieve dispersion of the slurry. Specifically, the stator 21 is provided with a first shearing portion 211, and the rotor 22 is provided with a second shearing portion 221. A plurality of stators 21 are arranged in sequence and a first gap 23 is provided between every two adjacent first shearing portions 211. A plurality of rotors 22 are arranged in sequence and a second gap 24 is provided between every two adjacent second shearing portions 221. The second shearing portion 221 on the rotor 22 is inserted into the first gap 23, and the first shearing portion 211 on the stator 21 is inserted into the second gap 24, so that each first gap 23 is provided with a second shearing portion 221, and each second gap 24 is provided with a first shearing portion 211. At this time, when the rotor 22 rotates relative to the stator 21, the rotor 22 and the stator 21 will shear the slurry against each other to achieve dispersion of the slurry.

[0040] In order to improve the dispersing effect of the first dispersing component 2 on the slurry, in this embodiment, a plurality of first shearing holes 2111 penetrating along the axial direction are arranged on the first shearing portion 211, and a plurality of second shearing holes 2211 penetrating along the axial direction are arranged on the second shearing portion 221.

[0041] The second dispersion component 3 specifically includes a rotating blade disc 31 and a baffle plate 32 both disposed in the second dispersion chamber 112. The baffle plate 32 is fixedly connected to the housing 1. The rotating blade disc 31 is rotationally connected to the housing 1. The rotating blade disc 31 rotates relative to the baffle plate 32 to shear the slurry together with the baffle plate 32 to achieve dispersion of the slurry. Specifically, the baffle plate 32 includes a main body 321 and two ribs 322 protruding from the main body 321. The two ribs 322 are both annular, and the two ribs 322 are arranged at intervals, so that an annular flow channel 323 is formed between the two ribs 322. The rotating blade disc 31 includes a connected base 311 and an annular boss 312. The boss 312 is embedded in the flow channel 323. When the rotating blade disc 31 rotates relative to the baffle plate 32, the rotating blade disc 31 and the baffle plate 32 can shear the slurry together.

[0042] In addition, in order to improve the dispersing effect of the second dispersing component 3 on the slurry, a plurality of third shearing holes 3221 are provided on both the two retaining edges 322, and a plurality of fourth shearing holes 3121 are provided on the boss 312. Moreover, when the rotating blade disc 31 rotates to any position relative to the baffle plate 32, the penetration direction of any third shearing hole 3221 and the penetration direction of any fourth shearing hole 3121 are not on the same straight line, thereby preventing the slurry from being discharged outward without being sheared by the rotating blade disc 31 and the baffle plate 32, ensuring that the slurry can be discharged outward only after being sheared by the rotating blade disc 31 and the baffle plate 32, so as to further improve the dispersing effect of the slurry.

[0043] Based on the use of the above-mentioned specific second dispersion component 3, the dispersion mechanism of the present solution also includes an impeller 4 arranged in the chamber 11, the impeller 4 is rotatably connected to the housing 1 and is located between the first dispersion component 2 and the second dispersion component 3, and the impeller 4 is used to drive the slurry flowing out of the first dispersion chamber 111 to flow into the second dispersion chamber 112 and then be discharged to the outside. Specifically, the impeller 4 is preferably fixed as a whole with the base 311 on the rotating blade 31, that is, the impeller 4 and the rotating blade 31 rotate synchronously, and the boss 312 on the rotating blade 31 is arranged around the outer periphery of the impeller 4. In addition, the impeller 4 has a self-priming characteristic, and the slurry located in the first dispersion chamber 111 has a tendency to automatically flow to the second dispersion chamber 112 due to the suction force of the rotation of the impeller 4, thereby enhancing the ability of the external slurry to spontaneously enter the first dispersion chamber 111 and enhance the ability of the slurry to be discharged to the outside. The pumping function of the impeller 4 can reduce the power of the external delivery pump or even replace the external delivery pump to simplify the appearance structure of the equipment.

[0044] Among them, the first dispersion chamber 111 is arranged above the second dispersion chamber 112, and correspondingly, the first dispersion component 2 is located above the second dispersion component 3, so that the slurry located in the first dispersion chamber 111 can spontaneously flow to the second dispersion chamber 112 due to its own weight, so as to reduce the power required by the impeller 4 to pump the slurry.

[0045] In this embodiment, the dispersion mechanism also includes a driving device 5, which includes a connected motor 51 and a rotating shaft 52. The motor 51 is fixedly connected to the shell 1 and is located outside the chamber 11. The rotating shaft 52 is rotatably connected to the shell 1 and extends into the chamber 11 and is sealed to the shell 1. The motor 51 is used to drive the rotating shaft 52 to rotate. The axis of the rotating shaft 52 is parallel to the vertical direction. Multiple rotors 22, rotating cutter discs 31 and impellers 4 are all fixed on the rotating shaft 52. When the rotating shaft 52 rotates, multiple rotors 22, rotating cutter discs 31 and impellers 4 can be driven to rotate synchronously at the same time.

[0046] In summary, the present invention provides two dispersion components. When the slurry enters the first dispersion chamber 111 of the housing 1, the slurry is firstly dispersed strongly for the first time by the joint shearing of the multiple stators 21 and the multiple rotors 22. The structure of using the stator 21 and the rotor 22 for slurry dispersion can also make the flow of the slurry almost unaffected by the centrifugal force, so that the slurry can be smoothly driven by the impeller 4 in the middle position and enter the second dispersion chamber 112, and then the baffle 32 and the rotating cutter disc 31 jointly shear to achieve the second dispersion. Compared with the traditional dispersion mechanism with only multiple stators 21 and rotors 22, the present invention can reduce the number of stators 21 and rotors 22. The number of stages used by the rotor 22 is used to shorten the distance that the slurry flows on the rotor 22 and the stator 21, thereby solving the problem of large flow loss of slurry with high viscosity after shearing through all the rotors 22 and all the stators 21. However, since the present solution also provides a second dispersion component 3 that cooperates with a baffle 32 and a rotating cutter disc 31 and an impeller 4 that drives the slurry to be discharged, although the number of stages of the stator 21 and the rotor 22 is reduced, the slurry discharged to the outside can still have a better dispersion effect. That is, the present solution is more suitable for dispersing slurries with large flow rates and high viscosities. After dispersion, the flow rate of the slurry will not be lost too much and it can still have a better dispersion effect.

[0047] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
