Description

Technical Field

[0001] The utility model relates to the technical field of pulping, in particular to an integrated powder-liquid disperser and a circulating pulping system. Background Art

[0002] In the new energy industry (such as lithium battery material preparation), the slurry preparation process generally involves adding different powder materials and liquid materials to the dispersion equipment in a quantitative and step-by-step manner according to the formula requirements, and mixing and dispersing them to achieve homogeneous dispersion between the powder and liquid materials.

[0003] The mixing module, dispersion module and slurry container of the existing pulping equipment are usually separately arranged in different equipment, and then connected by pipelines to realize material transportation. This method not only requires many connected pipelines, but also the length of the pipeline is long, the material transportation distance is long, and after the material is transported through the pipeline, a lot of material remains in the pipeline, resulting in large product losses.

[0004] At present, there are also pulping equipments which integrate the mixing module and the dispersing module together, while the slurry container is still separately arranged. The mixing module and the dispersing module are arranged in an upper mixing and lower dispersing manner (that is, the mixing module is arranged below the dispersing module). This arrangement has a large energy loss and a low effective workmanship. Moreover, since the slurry container is still separately arranged, the connecting pipelines between the slurry container and the mixing module and the dispersing module are still long, the material transportation distance is still relatively long, and the product loss is still relatively large. Utility Model Content

[0005] In view of the shortcomings of the above-mentioned existing pulping equipment, the applicant provides a rationally structured integrated powder-liquid disperser and a circulating pulping system, which integrates the slurry container, dispersion module, and mixing module into the same equipment, reduces connecting pipelines, shortens pipeline length, shortens material transportation distance, reduces product losses, reduces energy consumption, and improves effective workmanship.

[0006] The technical solution adopted by the utility model is as follows:

[0007] An integrated powder-liquid disperser, wherein a slurry container, a dispersing module, and a mixing module are arranged in sequence from top to bottom in the longitudinal direction, and a main shaft connected to a driving main unit is provided on the dispersing module and the mixing module; the dispersing module is provided with a dispersing chamber, and a first slurry inlet and a first slurry outlet communicating with the dispersing chamber; the mixing module is provided with a mixing chamber, and a second slurry inlet, a second slurry outlet, and a powder inlet communicating with the mixing chamber; the inner cavity of the slurry container is communicated with the first slurry inlet of the dispersing module, the first slurry outlet of the dispersing module is connected to the second slurry inlet of the mixing module, the second slurry outlet of the mixing module is connected to the slurry container, and the powder inlet of the mixing module is connected to a powder feeder.

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

[0009] The slurry container, the dispersion module and the mixing module are stacked in the longitudinal direction, and the driving host is arranged below the mixing module.

[0010] The first slurry inlet of the dispersion module is opened at the top, and the slurry container is installed on the top of the dispersion module.

[0011] The second slurry inlet, the second slurry outlet and the powder inlet of the mixing module are opened on the side.

[0012] The first slurry outlet of the dispersion module is connected to the second slurry inlet of the mixing module through a pipeline; the second slurry outlet of the mixing module is connected to the slurry container through a pipeline.

[0013] A cooling interlayer is arranged on the cylinder wall of the slurry container; a dispersing component is arranged in the dispersing cavity of the dispersing module; a mixing component is arranged in the mixing cavity of the mixing module; the powder feeder comprises a hopper and a conveying screw, the hopper is connected to the powder bin through a feeding pipeline, and one end of the conveying screw extends into the powder inlet of the mixing module; a cover is arranged on the outer cover of the slurry container, the dispersing module, the mixing module and the powder feeder.

[0014] A circulating pulping system, wherein the first pulp outlet of the dispersion module is connected to the first pulp outlet pipeline, the second pulp inlet of the mixing module is connected to the first pulp outlet pipeline through the pulp inlet pipeline, the second pulp outlet of the mixing module is connected to the second pulp outlet pipeline, and the first pulp outlet pipeline and the second pulp outlet pipeline are connected back to the pulp container through the pulp return pipeline.

[0015] As a further improvement of the above technical solution:

[0016] The first slurry outlet pipeline and the second slurry outlet pipeline are connected to a junction point, and the junction point is connected back to the slurry container through a return slurry pipeline; the junction point is also connected to a discharge pipeline.

[0017] A cooling device is provided on the slurry return pipeline.

[0018] A first valve is arranged on the first slurry outlet pipeline, and the connection point between the slurry inlet pipeline and the first slurry outlet pipeline is before the first valve; a second valve is arranged on the slurry inlet pipeline, a third valve is arranged on the second slurry outlet pipeline, a fourth valve is arranged on the slurry return pipeline, and a fifth valve is arranged on the discharge pipeline.

[0019] The beneficial effects of the utility model are as follows:

[0020] The utility model stacks and integrates the slurry container, the dispersion module and the mixing module longitudinally on the same device. This arrangement has the following advantages: (1) After the slurry container, the dispersion module and the mixing module are integrated, the device as a whole is more compact and occupies a smaller space volume; (2) The slurry container, the dispersion module and the mixing module are stacked longitudinally. On the one hand, the bottom of the slurry container is directly connected to the first slurry inlet of the dispersion module, saving the feed pipeline between the slurry container and the dispersion module; on the other hand, because the dispersion module and the mixing module are stacked and arranged closely longitudinally, the distance between the first slurry outlet of the dispersion module and the second slurry inlet of the mixing module is greatly shortened, so that the connecting pipeline between the first slurry outlet and the second slurry inlet can be greatly shortened. Since the feed pipeline between the slurry container and the dispersion module is saved and the conveying pipeline between the dispersion module and the mixing module is greatly shortened, the conveying distance of the material through the pipeline is greatly reduced, which not only greatly improves the material conveying efficiency, but also reduces the material residue in the pipeline and reduces the product loss; (3) The first slurry outlet pipeline of the dispersion module and the second slurry outlet pipeline of the mixing module share the same return slurry pipeline. The two modules return to the slurry container through the same return slurry pipeline, which saves the return slurry pipeline, reduces the material pipeline residue and reduces the product loss; (4) The dispersion module and the mixing module adopt the upper dispersion and lower mixing arrangement. The slurry container is close to the dispersion module. After the powder-liquid mixing stage is completed and the slurry dispersion stage is entered, the slurry inlet and outlet channels of the mixing module are closed. The slurry only needs to pass through the dispersion module and then return to the slurry container. This not only shortens the slurry conveying path in the slurry dispersion stage, improves the dispersion efficiency and reduces the product loss, but also because the mixing module does not convey materials in the slurry dispersion stage and is in an idling state, the energy consumption required by the mixing module is reduced, thereby reducing the overall energy loss of the equipment and improving effective workmanship.

[0025] The specific implementation of the present utility model is described below in conjunction with the accompanying drawings.

[0026] like Figure 1 , Figure 2 As shown, the utility model arranges a slurry container 1, a dispersion module 2, a mixing module 3, and a driving host 4 in sequence from top to bottom along the vertical direction. A main shaft 5 connected to the driving host 4 is passed through the dispersion module 2 and the mixing module 3. The driving host 4 can drive the rotating elements of the dispersion module 2 and the mixing module 3 to rotate at high speed through the main shaft 5.

[0027] A cooling interlayer 12 is provided on the wall surface of the cylinder 11 of the slurry container 1 for cooling the slurry in the slurry container 1 to ensure the quality of the slurry.

[0028] The dispersion module 2 is provided with a dispersion chamber 21, a dispersion assembly 22 is provided in the dispersion chamber 21, a first slurry inlet 23 is provided at the top of the dispersion module 2, a first slurry outlet 24 is provided at the bottom side of the dispersion module 2, and the first slurry inlet 23 and the first slurry outlet 24 are connected to the dispersion chamber 21. The slurry container 1 is installed at the top of the dispersion module 2, and the inner cavity of the slurry container 1 is connected to the first slurry inlet 23. The slurry in the slurry container 1 enters the dispersion chamber 21 of the dispersion module 2 from the first slurry inlet 23, and is dispersed from top to bottom through the dispersion assembly 22 and then output from the first slurry outlet 24.

[0029] The mixing module 3 is provided with a mixing chamber 31, in which a mixing assembly 32 is arranged. A second slurry inlet 33, a second slurry outlet 34 and a powder inlet 35 connected to the mixing chamber 31 are provided on the side of the mixing module 3. The second slurry inlet 33 is connected to the first slurry outlet 24 of the dispersion module 2 through a pipeline. The slurry dispersed by the dispersion module 2 enters the mixing chamber 31 of the mixing module 3 from the second slurry inlet 33, and is mixed with the powder fed from the powder inlet 35 through the mixing assembly 32 and then output from the second slurry outlet 34.

[0030] The powder inlet 35 of the mixing module 3 is connected to the powder feeder 6, and the powder feeder 6 includes a hopper 61 and a conveying screw 62. The hopper 61 is connected to the powder bin 7 through a blanking pipeline 10. One end of the conveying screw 62 is located below the hopper 61, and the other end extends into the powder inlet 35 of the mixing module 3. The powder in the powder bin 7 is delivered to the hopper 61 through the blanking pipeline 10, and is delivered to the mixing chamber 31 of the mixing module 3 via the conveying screw 62 to be mixed with the slurry.

[0031] The first slurry outlet 24 of the dispersion module 2 is connected to the first slurry outlet pipeline 20, and the first slurry outlet pipeline 20 is provided with a first valve 201. The second slurry inlet 33 of the mixing module 3 is connected to the first slurry outlet pipeline 20 through the slurry inlet pipeline 30. The connection point between the slurry inlet pipeline 30 and the first slurry outlet pipeline 20 is before the first valve 201, and the on-off of the slurry inlet pipeline 30 is not controlled by the first valve 201; the slurry inlet pipeline 30 is provided with a second valve 301. The second slurry outlet 34 of the mixing module 3 is connected to the second slurry outlet pipeline 40, and the second slurry outlet pipeline 40 is provided with a third valve 401. The first slurry outlet pipeline 20 and the second slurry outlet pipeline 40 are connected to the junction 70, and the junction 70 is connected back to the slurry container 1 through the return slurry pipeline 50. The return slurry pipeline 50 is provided with a cooling device 8 and a fourth valve 501, and the cooling device 8 cools the slurry. The junction 70 is also connected to a discharge pipeline 60 , through which the slurry can be discharged to the outside; a fifth valve 601 is provided on the discharge pipeline 60 .

[0032] like Figure 1 As shown, the utility model is further provided with a cover shell 9, which is arranged outside the slurry container 1, the dispersion module 2, the mixing module 3, the powder feeder 6 and the cooling device 8, so that the overall appearance of the equipment is neater and more beautiful.

[0033] The utility model arranges the slurry container 1, the dispersion module 2, and the mixing module 3 in a longitudinally stacked and integrated manner on the same device. Such an arrangement has the following advantages: (1) After the slurry container 1, the dispersion module 2, and the mixing module 3 are integrated, the device as a whole is more compact and occupies a smaller space volume; (2) The slurry container 1, the dispersion module 2, and the mixing module 3 are longitudinally stacked. On the one hand, the bottom of the slurry container 1 is directly connected to the first slurry inlet 23 of the dispersion module 2, saving the feed pipeline between the slurry container 1 and the dispersion module 2; on the other hand, since the dispersion module 2 and the mixing module 3 are longitudinally closely stacked, the distance between the first slurry outlet 24 of the dispersion module 2 and the second slurry inlet 33 of the mixing module 3 is greatly shortened, so that the connecting pipeline between the first slurry outlet 24 and the second slurry inlet 33 can be greatly shortened. Since the feed pipeline between the slurry container 1 and the dispersion module 2 is saved, the conveying pipeline between the dispersion module 2 and the mixing module 3 is greatly shortened, so the conveying distance of the material through the pipeline is greatly reduced, which not only greatly improves the material conveying efficiency, but also reduces the material residue in the pipeline and reduces the product loss; (3) The first slurry outlet pipeline 20 of the dispersion module 2 and the second slurry outlet pipeline 40 of the mixing module 3 share the same return slurry pipeline 50, and the two modules return to the slurry container 1 through the same return slurry pipeline 50, which saves the return slurry pipeline 50, reduces the pipeline residue of the material, and reduces the product loss; ( 4) The dispersing module 2 and the mixing module 3 are arranged in an upper dispersing and lower mixing manner. The slurry container 1 is close to the dispersing module 2. After the powder-liquid mixing stage is completed and the slurry dispersion stage is entered, the slurry inlet and outlet channels of the mixing module 3 are closed. The slurry only needs to pass through the dispersing module 2 and then return to the slurry container 1. This not only shortens the slurry conveying path in the slurry dispersion stage, improves the dispersion efficiency, and reduces product losses, but also because the mixing module 3 does not convey materials in the slurry dispersion stage and is in an idling state, the energy consumption required by the mixing module 3 is reduced, thereby reducing the overall energy consumption loss of the equipment and improving effective workmanship.

[0034] When the utility model is used for pulping, two stages are required: powder-liquid mixing and slurry dispersion. (1) Powder-liquid mixing stage: the first valve 201 and the fifth valve 601 are closed, the second valve 301, the third valve 401, and the fourth valve 501 are opened, and the slurry enters the dispersion module 2 from the slurry container 1, and after being dispersed by the dispersion module 2, enters the mixing module 3 to mix with the powder sent from the powder feeder 6, and then flows back to the slurry container 1 through the second slurry outlet pipeline 40 and the return slurry pipeline 50. (2) Slurry dispersion stage: the second valve 301, the third valve 401, and the fifth valve 601 are closed, the first valve 201 and the fourth valve 501 are opened, and the slurry enters the dispersion module 2 from the slurry container 1, and after being dispersed by the dispersion module 2, it circulates back to the slurry container 1 through the first slurry outlet pipeline 20 and the return slurry pipeline 50. After the pulping is completed, the second valve 301, the third valve 401, and the fourth valve 501 are closed, and the first valve 201 and the fifth valve 601 are opened, so that the pulp can be discharged.

[0035] The above description is an explanation of the utility model, not a limitation of the utility model. The utility model can be modified in any form without violating the spirit of the utility model.
