Description

Technical Field

[0001] This application relates to the field of mixers, and more particularly to a mixer. Background Technology

[0002] For sustainable development, green energy has become one of the most important measures for carbon reduction today. Among them, green energy lithium batteries are becoming increasingly popular. The lithium battery industry is developing rapidly, and its manufacturing equipment is constantly being iterated. There are various models of pulping equipment, but the mixer is still the mainstream.

[0003] In the pulping process of the lithium battery industry, mixers are mainly used to mix and disperse active agents, binders, conductive agents, and solvents to produce a slurry that meets process requirements. However, after pulping, slurry adheres to the top, inner wall, mixing impeller, and other component surfaces of the mixer. Over time, the amount of slurry adheres increases and may clump and dry, affecting the quality of subsequent homogenization.

[0004] Due to the switching of lithium battery models and the different materials used, the mixer needs to be cleaned. Currently, the traditional cleaning methods are manual wiping with a cloth or solvent spraying. However, both methods have certain drawbacks. Manual cleaning is inefficient, involves personnel contact with solvents, and requires special treatment of residues, making the resources unusable. While solvent rinsing improves efficiency to some extent, it uses a large amount of solvent, which cannot be discharged naturally and must be specially treated, making the process complex.

[0034] According to an embodiment of this application, a mixer is provided, which will be described below in conjunction with... Figure 1 Describe in detail the structure and working principle of the mixer.

[0035] According to an embodiment of this application, the mixer includes a tank 900, a heating mechanism, and a vibration mechanism. In an embodiment, the tank 900 has a cavity for containing materials to be mixed. The heating mechanism includes a heating element 100 disposed on the inner wall of the tank 900, and the heating element 100 is used to heat the inner wall of the tank 900. In an embodiment, the vibration mechanism includes a vibration element 200, and the vibration element 200 is used to cause the inner wall of the tank 900 to vibrate.

[0036] Thus, according to the mixer provided in this application embodiment, the mixer is equipped with a heating mechanism for heating the inner wall of the tank 900 and a vibration mechanism for causing the inner wall of the tank 900 to vibrate. The heating mechanism heats the material adhering to the inner wall of the tank 900, causing the material to quickly dry. Then, through vibration caused by the vibration mechanism, the dried material is vibrated off the inner wall of the tank 900, thereby achieving the cleaning of the material adhering to the tank 900. Compared to manual cleaning, this significantly improves efficiency; and compared to solvent rinsing, it eliminates the need for solvents and avoids the problems associated with solvent rinsing.

[0037] In this embodiment, the tank 900 included in the mixer may be cylindrical in shape, with an opening at the top for mounting a lid with a stirring paddle. Neither the stirring paddle nor the lid is shown in the figures. In this embodiment, it is understood that while the heating mechanism heats the inner wall of the tank 900, the heat also heats components such as the stirring paddle and lid where material adheres, causing the material on the surface of these components to dry out as described above. Simultaneously, due to the energy transfer from vibrations within the tank 900, the dried material on components such as the stirring paddle and lid will also be shaken off.

[0038] In the embodiments, the specific structures of the heating mechanism and the vibration mechanism will be described in the following description. In addition, the heating component 100 of the heating mechanism can be installed into the interior of the tank 900 by means of screws or the like, and the vibration component 200 of the vibration mechanism is the same.

[0039] According to the mixer provided in the embodiments of this application, the mixer may further include a collection mechanism, which may include a negative pressure component and a pipeline component 600. The pipeline component 600 may be connected to the bottom of the tank 900, and the negative pressure component may be connected to the pipeline component 600. The negative pressure component is used to generate negative pressure.

[0040] Thus, according to the mixer provided in the embodiments of this application, after the dried material falls to the bottom of the tank 900, a negative pressure can be generated by the negative pressure component, creating a pressure difference between the tank 900 (at this time, the tank cover is placed on the tank 900 to seal the cavity of the tank 900) and the negative pressure component, thereby causing the dried material to be sucked from the pipeline component 600 into the negative pressure component, thereby realizing the collection of the dried material.

[0041] As an example, the negative pressure assembly may include a storage device 700 and a vacuum component (not shown in the figure). The storage device 700 and the vacuum component are in communication. The storage device 700 is disposed between the vacuum component and the piping assembly 600. The storage device 700 may be, for example, a storage tank, with two openings communicating with the vacuum component and the piping assembly 600, respectively. A filter may be provided between the vacuum component and the storage tank to prevent dried-up material from entering the vacuum component. The vacuum component provides the negative pressure described above and may be, for example, a vacuum pump.

[0042] In this embodiment, the storage device 700, the vacuum component, and the piping assembly 600 can all be connected via quick-connect couplings, thereby facilitating the removal of the storage device 700 from the vacuum component and the piping assembly 600 to clean out any dried-up material.

[0043] According to the mixer provided in the embodiments of this application, the collecting mechanism may further include a valve component 500, which can be placed in the pipeline assembly 600 and can be used to control the opening and closing of the pipeline assembly 600. Thus, according to the mixer provided in the embodiments of this application, the valve component 500 can open the pipeline assembly 600, connecting the pipeline assembly 600 to the storage device 700, and can also disconnect the pipeline assembly 600, disconnecting it from the storage device 700. In this way, by controlling the opening and closing state of the valve component 500, the mixer can regulate the timing of sucking out the dried material inside, while when the valve component 500 is closed, it can ensure the internal sealing of the tank 900 and ensure the normal homogenization function of the mixer.

[0044] Furthermore, a specific example of valve component 500 will be described in the following description.

[0045] According to the mixer provided in the embodiments of this application, as an example, the heating component 100 includes an infrared heater. The number of heating components 100 is multiple, such as two, three, four, or even more, and they are arranged at equal intervals along the inner wall of the tank 900. That is, they are arranged at equal circumferential angles along the circumference of the tank 900 to provide a uniform heating effect.

[0046] According to the mixer provided in the embodiments of this application, the vibration assembly 200 may include an ultrasonic generator 210, a connecting member 220, and a vibration head 230. In the embodiments, the ultrasonic generator 210 may be disposed on the inner wall of the tank 900, i.e., connected to the inner wall of the tank 900 in the manner described above. The connecting member 220 may be connected to the ultrasonic generator 210, and the vibration head 230 may be connected to the connecting member 220. The vibration head 230 is rotatable about an axis extending in a vertical direction. In the embodiments, the connecting member 220 is used to transmit the energy of the ultrasonic generator 210 to the vibration head 230, and at the same time, through its own extension, provides the required height position for the corresponding vibration head 230. The rotation of the vibration head 230 can cause ultrasonic waves to radiate to every position inside the tank at its height, ensuring effective shaking off of dried material. Here, the vibration head 230 may be, for example, a conventional vibration head 230.

[0047] According to the mixer provided in the embodiments of this application, the number of vibration components 200 is multiple, such as 2, 3, 4 or even more, and at least two of the vibration heads 230 in each component have different heights. For example, three vibration heads 230 are provided, corresponding to the upper, middle and lower parts of the mixer tank 900, respectively, so that the upper, middle and lower regions of the mixer can all obtain ultrasonic energy vibration.

[0048] According to the mixer provided in the embodiments of this application, the connecting member 220 can extend and retract in the vertical direction, thereby adjusting the height of the vibrating head 230, so that the coverage height of the vibrating head 230 can be adjusted according to actual needs.

[0049] According to the mixer provided in the embodiments of this application, the mixer may further include a gas purification mechanism, which may include a gas pipeline 300 and a condensation collection device 400. In the embodiments, the gas pipeline 300 is connected to the tank 900, for example, connected to the top of the tank 900, and the condensation collection device 400 may be connected to the gas pipeline 300, and the condensation collection device 400 may be used to cool the gas introduced into the condensation collection device 400 by the gas pipeline 300.

[0050] In this embodiment, the solvent evaporated during the drying process of the material heated by the heating component 100 can enter the condensation collection device 400 via the gas pipeline 300. The condensation collection device 400 may include a condensation box, and the outside of the condensation box may be surrounded by a condensation water path and circulated with cooling water, so that the gaseous solvent is condensed into liquid and recovered in the condensation box, thereby purifying the gas from the gas pipeline 300. The gas with the recovered solvent after condensation can be discharged into the external environment.

[0051] According to the mixer provided in the embodiments of this application, the mixer may further include a monitoring mechanism and a stirring shaft. The monitoring mechanism may be connected to the stirring shaft to monitor the motion state of the stirring shaft. As an example, the monitoring mechanism may be, for example, an angular velocity sensor. Alternatively, the monitoring mechanism may be, for example, an encoder, thereby determining whether the stirring shaft is moving.

[0052] According to the mixer provided in the embodiments of this application, the mixer may further include a control mechanism 800. The control mechanism 800 may be communicatively connected to the monitoring mechanism, the heating mechanism, and the vibration mechanism. When the monitoring mechanism detects that the stirring shaft is not rotating, the control mechanism 800 may allow the heating mechanism and the vibration mechanism to be started. Alternatively, when the monitoring mechanism detects that the stirring shaft is rotating, the control mechanism 800 may disable the start of the heating mechanism and the vibration mechanism to avoid starting the heating mechanism and the vibration mechanism when the mixer is working.

[0053] Based on the technical features described above, the following will combine... Figure 1 The implementation of the mixer provided according to the embodiments of this application is described in further detail.

[0054] The mixer provided in the embodiments of this application can automatically clean the lithium battery homogenizer and recycle residual materials for reuse. The mixer provided in the embodiments of this application uses rapid heating to quickly dry residual paste materials, ultrasonic vibration to dry the materials, and negative pressure to automatically adsorb and collect the dried materials.

[0055] The heating mechanism, used to achieve rapid heating and baking, includes an infrared heater installed on top of the mixer (the number of infrared heaters depends on the size of the mixer and can be one or more). The infrared light emitted by the heater rapidly heats the entire tank 900, quickly raising the temperature to the set temperature and causing the material to dry rapidly. During drying, the solvent evaporates, generating vapor that enters the gas purification mechanism through a PTFE pipe (gas pipe) connected to the top of the mixer. The gas purification mechanism can employ distillation to cool and condense the organic solvent into a liquid, storing it in the solvent storage tank. The purified gas meets environmental standards and is then freely released.

[0056] In this embodiment, the heating mechanism is precisely controlled by the screen of the control mechanism 800. The cleaning control panel interface on the screen of the control mechanism 800 can have settings such as heating and baking temperature and time. The temperature and time settings are determined according to the materials and solvents used during homogenization, and the heating temperature is determined to be the optimal temperature for drying the residual materials.

[0057] The vibration mechanism may include an ultrasonic transmitter and three connecting rods (i.e., connecting components 220). Three transducers are connected to the connecting rods, which are retractable (e.g., existing multi-section telescopic structures) with adjustable extension length. During startup, the three connecting rods extend into the mixing tank. The three ultrasonic transmitter transducers are positioned at different locations in the upper, middle, and lower parts of the mixing tank. Each transducer contains a stepper motor and a worm gear. During operation, the motor rotates, driving the worm gear to rotate, causing the transducer to rotate 360 ​​degrees within the mixing tank (e.g., the motor drives the worm gear, which is coaxial with the transducer and rotates accordingly; the motor can be connected to the lower end of the connecting rod). This allows ultrasonic waves to radiate to every corner of the tank. The connecting rods between the ultrasonic transmitter and the transducers can be, for example, made of titanium alloy to ensure efficient transmission of ultrasonic energy and to quickly and efficiently dislodge dried materials.

[0058] The collection mechanism mainly includes a storage device 700 and PTFE pipes (pipeline assembly 600). The pipes are corrosion-resistant, high-temperature resistant, and have a smooth surface, making them resistant to clogging and corrosion of the adsorbed material. A negative pressure assembly generates strong negative pressure, which is connected to the bottom of the tank via the pipes, allowing the shaken-down material to be adsorbed into the storage device 700. Below the adsorption device is a pneumatic ball valve (valve component 500). The ball has a through hole in the center. When the adsorption function is activated, the control mechanism 800 automatically sends a signal to the ball valve, activating the solenoid valve on the ball valve. The solenoid valve opens, allowing compressed air to enter the pneumatic actuator. The pneumatic actuator converts the compressed air into mechanical kinetic energy, driving the ball to rotate 90 degrees. After rotation, the through hole aligns with the bottom pipe opening of the tank, thus opening the valve. When the adsorption function is deactivated, the ball valve automatically closes, and the ball and bottom pipe seal the bottom of the tank vertically, thus not affecting the normal homogenization function of the mixer.

[0059] According to the embodiment of this application, the control mechanism 800 of the mixer achieves precise control of the entire system. The control mechanism 800 sends an instruction to the rapid heating mechanism, and the heating mechanism starts working. After the heating mechanism finishes working, the vibration mechanism and the collection mechanism simultaneously receive the instruction from the control system, and the two mechanisms start working synchronously.

[0060] To ensure the reliable operation of the mixer, the entire control mechanism 800 is also equipped with a foolproof protection function, which includes two modules: access control and status monitoring.

[0061] The access control module ensures that only authorized quality personnel can start the system after confirming their login permissions. A user login interface is located on the control panel of the 800 control unit. This interface displays different usernames, each with a corresponding password. Usernames include Operator, Quality Administrator, and Equipment Maintenance Engineer, each corresponding to a different functional module. The operator interface has a separate cleaning control panel with a cleaning system start button and a cleaning system stop button. The cleaning system process is as follows: After logging in, the operator enters the cleaning control panel, clicks the cleaning start button (which changes from gray to red), and the system control panel displays a message indicating that cleaning has started and requesting quality personnel to confirm their login permissions, flashing a reminder. After confirming their login permissions, the quality personnel click "Confirm" to begin work. The interface then displays "Cleaning in progress." While cleaning is in progress, other operation buttons are automatically disabled by the system; all other buttons are grayed out and unresponsive, and a reminder that the equipment is cleaning in progress is displayed.

[0062] The status monitoring module mainly monitors the operating status of the mixer. It is equipped with a sensor inside the mixer. The sensor detects whether the mixer motor shaft is rotating to confirm the status of the mixer. The cleaning system button is only activated when the mixer is stationary. If the mixer is running, the cleaning system start button is disabled to prevent accidental operation.

[0063] The mixer provided in this application improves the recyclability of materials, effectively recovers residual materials during cleaning of the lithium battery homogenizer, and allows for the recycling of waste materials that originally caused some pollution, reducing production costs and contributing to the sustainable development of the lithium battery production industry. It also achieves renewable energy utilization and pollution-free emissions. Furthermore, it improves production efficiency; rapid baking, heating, and vibration adsorption cleaning methods are faster than traditional manual or spray washing processes, thus increasing production efficiency. It ensures effective cleaning, effectively cleaning the mixer and alleviating, to some extent, the problems of incomplete cleaning and difficult angle handling associated with traditional methods. In addition, it reduces occupational safety issues associated with manual contact with solvents.

[0064] When using the mixer in the embodiments of this application, as shown in the table below, the production efficiency is increased by 10-15% per year in cleaning and material handling, 5 tons of residual material are effectively collected, and the cost of recycling and processing materials is directly reduced by approximately 300,000 yuan.

[0065] Cleaning efficiency (per cleaning cycle / unit) Solvent used for cleaning (per unit) Total processing cost (per transaction / unit) Comparative Example 3-5 hours 0.5-1 ton 2000-3000 yuan Example 1-2 hours 0 700-1500 yuan

[0066] The above are merely preferred embodiments of this application and do not limit the scope of protection of this application. Any equivalent structural transformations made based on the innovative concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
