Description

Technical Field

[0001] The utility model relates to the technical field of material dispersion equipment, and particularly provides a self-priming powder-liquid homogenizing and shearing pump. Background Art

[0002] A shearing pump is a device used to uniformly mix and disperse different materials. Its dispersion effect is mainly achieved by the cooperation of the stator and rotor of the dispersion component. The material is dispersed after being subjected to strong mechanical and hydraulic shearing and centrifugal extrusion in the narrow gap between the stator and the rotor. A centrifugal pump is a device that transports materials by generating centrifugal force. Its transportation effect mainly relies on the coordinated work of the centrifugal impeller and the volute. Under the action of the centrifugal force generated by the high-speed rotation of the centrifugal impeller, the material is accelerated and discharged through the volute, thus achieving efficient and continuous transportation.

[0003] In the field of battery material production, the positive and negative electrode materials of the battery and deionized water are mixed and processed through a sizing system to obtain the positive and negative electrode slurries of the battery. In the existing sizing system, an independent shearing pump and a centrifugal pump are usually equipped separately; the powder material and the solvent are mixed and shear-dispersed through the dispersion component of the shearing pump, and then transported to the centrifugal pump; under the action of the centrifugal pump, the mixed and shear-dispersed slurry is accelerated and transported to the next process. However, the use of two independent devices occupies a large installation space, which increases the difficulty of system layout for factories or production lines with limited space.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0030] like Figures 1 to 2 As shown, the embodiment of the utility model provides a self-priming powder and liquid uniform cutting pump, which includes a pump body 1, a rotating shaft 2, a motor 7 and a base 8. The pump body 1 is fixedly mounted on the base 8 through a first mounting bracket 81, and the motor 7 is fixedly mounted on the base 8 through a second mounting bracket 82. The axis of the rotating shaft 2 is arranged in a horizontal direction, the starting end of the rotating shaft 2 is drivingly connected to the driving shaft 71 of the motor 7, and the end of the rotating shaft 2 penetrates into the pump body 1 and is connected to the components inside the pump body 1.

[0031] like Figures 3 to 5As shown in the figure, the pump body 1 includes a pump chamber 14. Inside the pump chamber 14, a dispersion component 12 and a centrifugal component 13 are sequentially arranged along the axial direction of the rotating shaft 2. The dispersion component 12 includes a stator 121 and a rotor 122. The stator 121 is fixedly arranged inside the pump chamber 14. The stator 121 is rotationally matched with the rotor 122. The rotor 122 can disperse the materials inside the pump chamber 14 by rotating. The centrifugal component 13 includes a centrifugal impeller 131. The centrifugal impeller 131 can transport the materials inside the pump chamber 14 by rotating. The rotor 122 and the centrifugal impeller 131 are respectively connected to the rotating shaft 2, so that the rotating shaft 2 can drive the rotor 122 and the centrifugal impeller 131 to rotate simultaneously.

[0032] Specifically, a plurality of first shear teeth are formed on the stator 121 at intervals along its circumferential direction. A plurality of second shear teeth are formed on the rotor 122 at intervals along its circumferential direction. During the rotation of the rotor 122 relative to the stator 121, the wall surface of the second shear teeth can be opposite or misaligned with the wall surface of the first shear teeth. The second shear teeth and the first shear teeth are used for mixing and shear dispersion of the powder-liquid materials.

[0033] As Figure 3 and Figure 4 shown in the figure, the pump chamber 14 has a feed port 141 and a discharge port 142. The feed port 141 and the discharge port 142 are respectively communicated with the inside of the pump chamber 14. The feed port 141 is opened along the axial direction of the rotating shaft 2. The discharge port 142 is opened along the radial direction of the rotating shaft 2 and is correspondingly arranged with the centrifugal impeller 131. In the embodiment of the present utility model, by correspondingly arranging the discharge port 142 with the centrifugal impeller 131, when the centrifugal impeller 131 rotates at a high speed, after the powder-liquid materials contact the centrifugal impeller 131, they will be thrown out radially outward along the centrifugal impeller 131 under the action of centrifugal force, so as to be accelerated and transported to the next process through the discharge port 142.

[0034] The working principle of the self-priming powder-liquid homogenizing pump in the embodiment of the present utility model is as follows: First, start the motor 7 so that the drive shaft 71 of the motor 7 drives the rotor 122 of the dispersion component 12 and the centrifugal impeller 131 of the centrifugal component 13 to rotate simultaneously through the rotating shaft 2. Then, the powder-liquid materials enter the inside of the pump chamber 14 through the feed port 141. Under the high-speed rotation of the centrifugal impeller 131, a low-pressure area will be formed at the center of the centrifugal impeller 131. This low pressure will cause the powder-liquid materials to be sucked to the centrifugal impeller 131, so that the powder-liquid materials are transported to the centrifugal component 13 through the dispersion component 12, thereby enabling the homogenizing pump to achieve the effect of self-priming powder-liquid materials. When the powder-liquid materials pass through the dispersion component 12, during the rotation of the rotor 122 relative to the stator 121, the powder-liquid materials will be mixed and shear-dispersed. Subsequently, when the powder-liquid materials reach the centrifugal component 13, the high-speed rotating centrifugal impeller 131 will throw the powder-liquid materials radially outward, so that the powder-liquid materials can be accelerated and transported to the next process through the discharge port 142.

[0035] The self-priming powder-liquid homogenizing pump provided by the utility model simultaneously sets a dispersing component 12 and a centrifugal component 13 in the pump chamber 14, and the rotor 122 of the dispersing component 12 and the centrifugal impeller 131 of the centrifugal component 13 are respectively connected to the rotating shaft 2, so that the rotating shaft 2 can drive the rotor 122 and the centrifugal impeller 131 to rotate simultaneously, and further enable the powder-liquid material to be mixed, sheared and dispersed in the pump chamber 14 and accelerated to the next process. In the glue-making system, compared with the scheme of separately and independently setting a shearing pump and a centrifugal pump, the self-priming powder-liquid homogenizing pump in the utility model combines the functions of the shearing pump and the centrifugal pump. Using the self-priming powder-liquid homogenizing pump in the utility model can replace the shearing pump and the centrifugal pump, thereby reducing the installation space of the equipment and improving the space utilization rate.

[0036] Continue to refer to Figure 3 and Figure 4 As shown in the figure, there are multiple dispersing components 12, and the multiple dispersing components 12 are arranged along the axial direction of the rotating shaft 2. In this embodiment, the number of the dispersing components 12 is 2. It should be noted that the number of the dispersing components 12 is not limited to 2 shown in the figure, and can be 1, 3, 4, etc. The appropriate number of the dispersing components 12 can be selected according to the requirements of mixing and shearing and dispersing the powder-liquid material in actual applications.

[0037] Continue to refer to Figure 3 and Figure 4 As shown in the figure, a guiding component 11 is arranged in the feed inlet 141. The guiding component 11 includes a spiral blade 111. The spiral blade 111 can guide the material into the pump chamber 14 by rotating. The spiral blade 111 is installed at the end of the rotating shaft 2, so that the rotating shaft 2 can drive the spiral blade 111 to rotate. In the embodiment of the utility model, by arranging the guiding component 11 at the feed inlet 141, the spiral blade 111 can guide the powder-liquid material into the pump chamber 14 and can stir the powder-liquid material at the feed inlet 141 to a certain extent, thereby preventing the powder-liquid material from being blocked at the feed inlet 141 during the conveying process.

[0038] As Figure 6 shown, the pump chamber 14 further has at least one sewage discharge port 143. The sewage discharge port 143 is communicated with the inside of the pump chamber 14, and an opening and closing valve 1431 is arranged at the sewage discharge port 143. The opening and closing valve 1431 is used to control the on-off state of the sewage discharge port 143. In this embodiment, the pump chamber 14 has two sewage discharge ports 143, and the two sewage discharge ports 143 are respectively communicated with the bottom of the pump chamber 14. Through the above setting, when the homogenizing pump is working, the opening and closing valve 1431 is closed to make the sewage discharge port 143 in a blocked state, and the powder-liquid material cannot be discharged from the sewage discharge port 143; after the homogenizing pump stops working, the opening and closing valve 1431 is opened to make the sewage discharge port 143 in a communicated state, so that the residual powder-liquid material in the pump chamber 14 can be discharged out of the pump chamber 14 through the sewage discharge port 143.

[0039] Continue to refer to Figures 2 to 4 , the slicing pump further includes a mechanical seal 3 and a water cooling chamber 4. The mechanical seal 3 is sleeved on the rotating shaft 2 and installed on the side wall of the pump chamber 14 near the starting end of the rotating shaft 2, so that the rotating shaft 2 passes through the mechanical seal 3 and enters the pump chamber 14. The inside of the water cooling chamber 4 is used to accommodate the mechanical seal 3 and can be filled with cooling water to reduce the temperature of the mechanical seal 3. The mechanical seal 3 is located inside the water cooling chamber 4, and the water cooling chamber 4 is installed on the side wall of the pump chamber 14 near the starting end of the rotating shaft 2. By providing the mechanical seal 3 in the embodiment of the present invention, it is possible to prevent the powder-liquid material from leaking from the pump chamber 14. In addition, by providing the water cooling chamber 4 in the present invention, the temperature of the mechanical seal 3 can be reduced.

[0040] Further, as Figure 7 shown, the water cooling chamber 4 has a water inlet 41 and a water outlet 42. The water inlet 41 and the water outlet 42 are respectively communicated with the inside of the water cooling chamber 4, and the water inlet 41 and the water outlet 42 are arranged opposite to each other. Through the above arrangement, the cooling water can enter the inside of the water cooling chamber 4 through the water inlet 41 and be discharged through the water outlet 42.

[0041] As Figure 8 shown, the slicing pump further includes a bearing chamber 5 and a connection chamber 6. The pump body 1, the water cooling chamber 4, the bearing chamber 5 and the connection chamber 6 are arranged in sequence along the axial direction of the rotating shaft 2. Two bearing members 51 are respectively provided on the two side walls of the bearing chamber 5 in the axial direction of the rotating shaft 2, and the rotating shaft 2 passes through the bearing chamber 5 through the two bearing members 51. The inside of the connection chamber 6 is used to accommodate the coupling 61, and the starting end of the rotating shaft 2 is drivingly connected to the driving shaft 71 of the motor 7 through the coupling 61.

[0042] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
