Description

Technical Field

[0001] The present invention relates to the field of pulp making technology, specifically, it relates to a homogenizer.Technical Background

[0002] In the production of lithium-ion battery electrodes, the positive electrode slurry consists of binders, conductive agents, positive electrode materials, etc.; while the negative electrode slurry comprises binders, graphite powder, etc. The preparation of both positive and negative electrode slurries involves a series of processes such as mixing, dissolving, and dispersing between liquids and solids, with variations in temperature, viscosity, and environment during the process. The dispersibility and uniformity of the granular active material in the positive and negative electrode slurries directly affect the movement of lithium ions between the two electrodes of the battery. Therefore, the mixing and dispersion of the slurry for each electrode material is crucial in the production of lithium-ion batteries. The quality of slurry dispersion directly impacts the subsequent production quality of lithium-ion batteries and their product performance.

[0003] To produce the slurry, a homogenizing process is required, which involves adding various raw materials into a blender for slurry preparation. The blender consists of components such as a mixing tank, a stirring shaft, and a motor to drive the shaft. In related technologies, the shaft and the motor that drives it are generally mounted on the cover of the mixing tank, with the shaft extending into the tank to stir the slurry.

[0004] With the shaft and the motor that drives it mounted on the cover, there is no space left on the cover to arrange other components like feed inlets. Other components have to be distributed separately on the mixing tank, leading to an increase in the overall equipment size, unreasonable component arrangement, and higher production costs.Summary of the Invention

[0005] The present invention aims to address one of the technical issues in related technologies to a certain extent. To this end, the invention provides a blender with the advantages of compact structure and low production cost.

[0006] To achieve the above purpose, the present invention adopts the following technical solution: A slurry mixer characterized by comprising: a stirring tank, which includes a stirring assembly, a inner cavity labeled of a tank body, and the tank body is covered by a cover body at its top. The stirring assembly comprises a main shaft and on the main shaft of the device, a stirring paddle is arranged. The stirring paddle is arranged inside the tank body and located at the bottom of the tank body. One end of the main shaft connected to the stirring paddle is located inside the tank body, and the other end of the main shaft penetrates out from the bottom of the tank body. On the top surface of the cover body, an installation surface is formed, and the tank body features a discharge port at its bottom.

[0007] Multiple functional devices, with at least one of the functional devices being arranged on the installation surface.

[0008] The present invention provides a blender that includes a mixing tank for holding slurry and a cover that covers the top of the tank body. The main shaft of the mixing tank is placed at the bottom of the tank, and a high-speed motor that drives the main shaft is arranged on one side of the tank body, making it convenient to place functional devices on the cover. The upper surface of the cover forms an installation surface, and multiple functional devices are arranged on the installation surface. Some of the functional devices are relatively small in size and suitable for being concentrated on the cover, avoiding their separate placement, resulting in a compact overall structure of the blender.

[0009] Optionally, the blender further includes a flow disturbing plate, which is arranged inside the tank and extends towards the bottom wall of the tank. At least a part of the flow disturbing plate is located between the stirring paddle and the inner sidewall of the tank. The functional device includes a low-speed motor, which is set on the installation surface and connected to the flow disturbing plate to drive the flow disturbing plate to rotate around the output shaft of the low-speed motor.

[0010] The functional device comprises a flow disturbing plate and a low-speed motor for driving the flow disturbing plate to rotate. The flow disturbing plate is used to prevent the circumferential flow of slurry driven by the stirring paddle. The flow disturbing plate extends downward inside the tank, and the slurry moves upward along the flow disturbing plate under its interference, avoiding the circumferential flow of slurry only under the action of the stirring paddle. The flow disturbing plate enables the slurry to circulate up and down, achieving mixing during the circulation process, resulting in more uniform stirring of the slurry. Among them, the low-speed motor is also arranged on the installation surface.

[0011] Optionally, the flow disturbing plate includes a connecting section and a disturbing section. The first end of the connecting section is set at the bottom of the cover and connected to the low-speed motor. The second end of the connecting section is set towards the inner wall of the tank. The first end of the disturbing section is connected to the second end of the connecting section, and the disturbing section extends towards the bottom of the tank, with its second end located between the stirring paddle and the inner wall of the tank.

[0012] The connecting section of the flow disturbing plate is inclined towards the inner sidewall of the tank to facilitate disturbing the circumferential flow of slurry within the chamber. The disturbing section extends towards the bottom of the tank, allowing slurry to climb upwards along the disturbing section, enhancing the vertical circulation flow of slurry. The connecting section is fixed at the bottom of the cover, with its first end connected to the low-speed motor, and the disturbing section is fixed to the second end of the connecting section near the inner sidewall of the tank. When the low-speed motor drives the connecting section to rotate, the disturbing section also rotates, enhancing the vertical circulation of slurry and improving the blending effect. The end of the connecting section extends beyond the outer edge of the stirring paddle to prevent the flow disturbing plate from interfering with the rotation of the stirring paddle during operation, avoiding damage to parts. The simultaneous operation of the stirring paddle and the flow disturbing plate enables the slurry to flow both circumferentially and vertically, resulting in a more uniform mixture of slurry.

[0013] Optionally, the end of the connecting section near the cover is connected to the low-speed motor through a sealing element that runs through the center of the cover. The low-speed motor is arranged on the side of the sealing element away from the flow disturbing plate. The sealing element is fixed to the cover, and the output shaft of the low-speed motor passes through the sealing element and connects to the connecting section.

[0014] The connecting section is connected to the output shaft of the low-speed motor via the sealing element and rotatably mounted at the center of the cover. The sealing element prevents slurry from spilling out of the cover. The low-speed motor drives the connecting section to rotate, and simultaneously, the connecting section drives the disturbing section to rotate. The low-speed motor is arranged directly above the sealing element, with its output shaft directly connected to the connecting section, eliminating redundant components and allowing feed devices to be arranged around the low-speed motor.

[0015] Optionally, the length of the disturbing section is at least greater than two-thirds of the length of the inner chamber, ensuring that the slurry in the chamber can be fully stirred.

[0016] Optionally, the functional devices include a feeding device set on the installation surface. A feed inlet that runs through the thickness of the cover is formed on the cover, and the material provided by the feeding device enters the inner chamber through the feed inlet.

[0017] Optionally, the feeding device further includes a hopper, the outlet of the hopper is set in the feed inlet, and the hopper is arranged on the side of the installation surface facing away from the tank.

[0018] The hopper is used to inject slurry into the inner chamber of the tank. The feed inlet is formed through the cover to create a feed channel, allowing slurry to enter the hopper and then enter the inner chamber through the feed channel. The hopper is positioned directly above the cover, saving space on both sides of the mixing tank and making the overall structure more compact. Users can add materials to the tank without opening the cover, which is convenient for operation and improves production efficiency.

[0019] Optionally, the functional devices include a high-speed motor that connects to the main shaft to drive its rotation. The high-speed motor is arranged on one side of the tank. The main shaft is centrally located through the bottom wall of the tank, and the high-speed motor drives the part of the main shaft located outside the tank through a transmission mechanism. The stirring paddle is fixed to the part of the main shaft located within the inner chamber.

[0020] The main shaft is positioned in the center of the bottom wall of the tank, and the high-speed motor is located on the side of the main shaft and connected to it through devices such as belts, chains, or couplings. The belt transmits kinetic energy to the main shaft to drive the stirring paddle to rotate and break up the slurry. It is worth noting that the volume of the low-speed motor used in this invention is smaller than that of the high-speed motor. Therefore, when the low-speed motor is arranged on the cover, there is still space on the cover to install other components such as the feeding device. The high-speed motor has a larger volume. When the high-speed motor is placed on the cover, other components can only be tilted and placed on the side of the cover or the tank, resulting in a larger overall volume of the equipment, scattered components, a more complex structure, which is not easy to maintain and replace parts, inconvenient for operation, and affects the blending efficiency.

[0021] Optionally, the functional devices also include a lighting component and an observation component. A lighting opening that runs through the cover is formed on the cover, and the lighting component is fitted into the lighting opening. A concave observation opening is also formed on the cover relative to the installation surface, and the observation component, which is at least partially transparent, is fitted into the observation opening. The cooperation of the lighting opening and the observation opening allows the cover to be visualized, making it easy for users to observe the mixing state of the slurry in the inner chamber of the tank.

[0022] Optionally, the functional devices also include a sensor. At least one sensor is set on the cover, including a sensing element extending into the tank and a conversion element located above the installation surface. The conversion element of the sensor is located above the installation surface, while the sensing element is located inside the tank. The sensing element refers to the part that can perceive the physical quantity inside the tank, and the conversion element refers to the part that converts the perceived physical quantity into an electrical signal.

[0023] The present invention, as an option, may employ one or several of the following sensors: a temperature sensor, a detection sensor, and a pressure sensor. The temperature sensor is used to detect the temperature inside the tank, the detection sensor is used to detect the liquid level inside the tank, and the pressure sensor is used to monitor the pressure inside the tank. These sensors can assist users in monitoring physical parameters within the tank, thus reducing potential safety hazards.

[0024] Furthermore, the cover of the tank may be provided with at least one standby port that is connected to the interior of the tank. This standby port can be used to install sensors or piping, making it convenient for cleaning, filling, draining, and maintenance. It also provides a contingency measure for unexpected situations. 1. In this invention, the high-speed motor is positioned on the side of the mixing tank, leaving space on the cover for the installation of other small-sized functional devices such as a feeding device, a low-speed motor, and sensors. The centralized placement of these small-sized functional devices results in a compact overall structure of the homogenizer, facilitating maintenance and component replacement. 2. The baffle plate comprises a connection segment connected to the low-speed motor and a downwardly extending turbulence-generating segment. The low-speed motor drives the baffle plate to rotate, enhancing the up-and-down circulation of the slurry inside the tank, thereby improving the homogenization effect. The low-speed motor is also positioned on the cover, further enhancing the compactness of the homogenizer.

[0028] Here, a detailed description of an embodiment of the present invention is provided, with examples shown in the accompanying drawings. Throughout the description, identical or similar reference numerals refer to identical or similar elements or elements having identical or similar functions. The embodiments described in the implementation modes are intended to explain the invention and should not be construed as limiting the invention.

[0029] In this specification, the phrase "an embodiment" or "an instance" or "an example" refers to a particular feature, structure, or characteristic described in connection with the embodiment itself that can be included in at least one embodiment of the present disclosure. The appearance of the phrase "in one embodiment" at various places in the specification does not necessarily refer to the same embodiment.Embodiment:

[0030] As shown in Figures 1, 2, and 3, this embodiment provides a homogenizer comprising: a mixing tank 1, including a stirring assembly, a tank body 11 with an inner chamber 113, and a cover 12 that covers the top of the tank body 11. As shown in Figure 5, the stirring assembly includes a main shaft 112 and a stirring paddle 111 mounted on the main shaft 112. The stirring paddle 111 is disposed in the tank body 11 and located at the bottom of the tank body 11. One end of the main shaft 112 connected to the stirring paddle 111 is located inside the tank body 11, and the other end of the main shaft protrudes from the bottom of the tank body 11. The top surface of the cover 12 forms a mounting surface 121, and the bottom of the tank body 11 forms a discharge port 114. Multiple functional devices are provided, with at least one functional device being disposed on the mounting surface 121.

[0031] In this embodiment, the mixing tank 1 is configured as a cylindrical shape, and the inner chamber 113 it forms is also a cylindrical deep-bottom inner chamber 113. The cover 12 covers the top of the tank body 11, and the shape of the cover 12 is configured as a circular plate that matches the tank body 11 to close the inner chamber 113. In other embodiments, the mixing tank 1 can also be configured as a truncated cone shape or a rectangular parallelepiped shape, and the shape of the cover 12 should adapt to the shape of the mixing tank 1. Specifically, the cross-section and size of the cover 12 should be adapted to the cross-section and size of the mixing tank 1 to achieve the purpose of closing the inner chamber 113 and preventing slurry overflow. The upper end surface of the cover 12 forms a horizontal mounting surface 121 for arranging functional devices on the mounting surface 121.

[0032] As shown in Figures 3 and 4, the homogenizer further includes a baffle plate 3, which is arranged inside the tank body 11 and extends towards the bottom wall of the tank body 11. At least a portion of the baffle plate 3 is located between the stirring paddle 111 and the inner sidewall of the tank body 11. The functional devices include a low-speed motor 4, the low-speed motor 4 is disposed on the mounting surface 121 and connected to the baffle plate 3 to drive the baffle plate 3 to rotate around the output shaft of the low-speed motor 4.

[0033] The baffle plate 3 is set inside the tank body 11 to block the circumferential flow of slurry driven by the stirring paddle 111. The upper end of the baffle plate 3 is rotatably mounted on the cover 12, and the lower end extends towards the bottom wall of the tank body 11. The tank body 11 has an inner chamber 113 where the slurry flows circumferentially, when touching the baffle plate 3, will climb up along the baffle plate 3 and then fall under the action of gravity, completing an up-and-down circulating flow, which improves the homogenizing effect. The low-speed motor 4 is fixed on the mounting surface 121, and its output shaft is connected to the baffle plate 3 to drive the baffle plate 3 to rotate. When the baffle plate 3 rotates, it can block the circumferential flow of slurry driven by inside the tank body 11, the stirring paddle 111 is located at multiple positions. In other embodiments, the baffle plate 3 can also be fixed to the inner wall of the tank body 11.

[0034] It should be noted that the slurry mainly undergoes the homogenizing process under the action of the stirring paddle 111, so the speed of the high-speed motor 2 is relatively high to facilitate efficient mixing of the slurry. The baffle plate 3 is used to assist in homogenizing the slurry and enhancing the up-and-down circulation of the slurry, so only a low-speed motor 4 with a lower rotational speed is required.

[0035] The functional devices include a feeding device 1211, the feeding device 1211 is disposed on the mounting surface 121. The cover 12 which is mentioned above, on the cover 12, a feed inlet 1211a is formed that penetrates through the thickness direction of the cover, and the material provided by the feeding device 1211 and through the feed inlet 1211a, access is gained to the inner chamber 113. The feeding device 1211 further includes a hopper 1211b, with the outlet of the hopper 1211b set in the feed inlet 1211a, and the hopper 1211b disposed on the side of the mounting surface 121 facing away from the tank body 11.

[0036] The feed inlet 1211a is arranged to penetrate through the cover 12 and communicate with the underlying inner chamber 113. A vertical hopper 1211b is fixed above the feed inlet 1211a through a clamp. The top of the hopper 1211b is provided with an upper cover for closing the hopper 1211b, and the side of the upper cover is distributed with clamping platforms. The side of the hopper 1211b is distributed with clips that engage with the clamping platforms. By separating the clips from the clamping platforms, the upper cover can be opened to feed slurry into the hopper 1211b.

[0037] The baffle plate 3 includes a connecting section 31 and a flow disturbing section 32. The first end of the connecting section 31 is set at the bottom of the cover 12 and connected to the low-speed motor 4. The second end of the connecting section 31 is oriented towards the inner wall of the tank body 11. The first end of the flow disturbing section 32 is connected to the second end of the connecting section 31, and the flow disturbing section 32 extends towards the bottom of the tank body 11, with its second end located between the stirring paddle 111 and the inner wall of the tank body 11.

[0038] The connecting section 31 is inclined towards the inner sidewall of the tank body 11 and does not contact the inner sidewall, allowing the baffle plate 3 to be biased towards the inner sidewall of the tank body 11, facilitating the disturbance of slurry flowing circumferentially along the tank body 11. The upper end of the connecting section 31 is set at the bottom of the cover 12, and the flow disturbing section 32 is connected to the lower end of the connecting section 31 to facilitate extension towards the bottom wall of the tank body 11. In the vertical direction, the flow disturbing section 32 extends to a position not exceeding the bottom surface of the stirring paddle 111. That is, the baffle plate 3 is also set on the cover 12 and located at the installation position of the main shaft 112 mentioned in related technologies, further enhancing the compactness of the homogenizer structure. In other embodiments, the flow disturbing section 32 can also be integrally formed with the connecting section 31.

[0039] The end of the connecting section 31 near the inner sidewall of the tank body 11 exceeds the outer edge of the stirring paddle 111 in the horizontal direction, and the length of the flow disturbing section 32 is at least greater than two-thirds of the length of the inner chamber 113.

[0040] In the horizontal direction, the end of the connecting section 31 near the inner sidewall of the tank body 11 exceeds the outer edge of the stirring paddle 111 to avoid interfering with the operation of the stirring paddle 111. When the end of the connecting section 31 near the inner sidewall of the tank body 11 exceeds the outer edge of the stirring paddle 111, the connecting section 31, near the inner sidewall, has its end naturally connected to the vertical flow disturbing section 32 also exceeds the outer edge of the stirring paddle 111 in the horizontal direction. This means that the baffle plate 3 overall does not interfere with the stirring paddle 111. Specifically, the length of the flow disturbing section 32 is designed to be two-thirds of the length of the inner chamber 113, allowing most of the slurry to contact the flow disturbing section 32 and enhancing the slurry mixing effect. It should be noted that the bottom of the flow disturbing section 32 cannot touch the bottom wall of the mixing tank 1 to avoid damaging the homogenizer.

[0041] The end of the connecting section 31 near the cover 12,and the cover 12 has a sealing element 122 penetrably installed in its center, and this sealing element connects to the low-speed motor 4. The low-speed motor 4 is positioned on the side of the sealing element 122 opposite to the baffle plate 3; the sealing element is fixed on the cover 12, and the output shaft of the low-speed motor 4 passes through the sealing element 122 and connects to the connecting section 31.

[0042] The sealing element 122 is fitted around the end of the connecting section 31 near the cover 12, and the sealing element 122 is penetrably installed in the center of the cover 12. The outer circumference of the sealing element 122 closely fits with the cover 12 to prevent slurry from spilling over the cover 12. Specifically, the sealing element 122 is an oil seal. In other embodiments, the sealing element 122 can also be a sealing ring, gasket, or the like. The oil seal is fixed to the cover 12 through bolts, and the end of the connecting section 31 near the cover 12 forms a disc that connects with the sealing element 122. Below the disc is a pressure plate that connects to the output shaft of the low-speed motor 4 through bolts, allowing the disc to rotate under the driving force of the low-speed motor 4.

[0043] The functional device includes a high-speed motor 2, which is connected to the main shaft 112 to drive the main shaft 112 rotation. The high-speed motor 2 is positioned on one side of the tank body 11. The main shaft 112 penetrates through the center of the bottom wall of the tank body 11, and the high-speed motor 2 drives the portion of the main shaft 112 outside the tank body 11 through a transmission mechanism. The stirring paddle 111 is fixed to the portion of the main shaft 112 located in the inner chamber 113.

[0044] The main shaft 112 penetrates through the bottom of the tank body 11, with one end located outside the tank body 11 and driven by the high-speed motor 2, and the other end located inside the tank body 11 with the stirring paddle 111 attached. Under the action of the high-speed motor 2, the main shaft 112 drives the stirring paddle 111 to rotate and stir the slurry. The high-speed motor 2 has a relatively large volume and is adjacent to and placed on one side of the tank body 11. Compared to the arrangement of the high-speed motor 2 on the cover 12 in related technologies, this arrangement in the embodiment leaves space on the cover 12 for many smaller components. The high-speed motor 2 drives the portion of the main shaft 112 outside the tank body 11 through transmission mechanisms such as belts, gears, or chains, the stirring paddle 111, attached to a portion of the main shaft 112, causes the main shaft portion to rotate within the inner chamber 113. The stirring paddle 111 is disc-shaped, enabling the slurry to flow circumferentially along the tank body 11. Specifically, one end of the belt is fitted on the main shaft 112, and the other end is fitted on the output shaft of the high-speed motor 2. In other embodiments, the high-speed motor 2 and the main shaft 112 can also be connected through devices such as couplings.

[0045] The functional device also includes a lighting element 1231 and an observation element 1241. On the cover body 12,the cover body 12 has a lighting port 123 formed that penetrates through it, and the lighting port 123 is equipped with the inner chamber 113 is illuminated by a lighting element 1231.

Specifically, the lighting element 1231 can be an LED light, a fluorescent light, an incandescent light, etc. In this embodiment, the observation element 1241 is a fully transparent glass; in other embodiments, the observation element 1241 can also be partially transparent plastic, etc. The selected observation element 1241 should meet the requirement that at least a portion of it can unobstructedly view the slurry in the inner chamber 113.

[0048] The sensor 125 can sense the measured physical quantity through the sensing element and convert the sensed physical quantity into an electrical signal through the conversion element according to a certain rule, allowing users to obtain intuitive results and facilitating the detection of the situation inside the tank body 11.

[0049] The sensor 125 can be one or several of a temperature sensor 125, a detection sensor 125, and a pressure sensor 125. In this embodiment, the sensor 125 is a temperature sensor 125, a detection sensor 125, and a pressure sensor 125, respectively monitoring the temperature, liquid level, and pressure inside the tank body 11.
