Description

Technical Field

[0001] This utility model belongs to the technical field of ternary precursor production equipment, specifically, it relates to a mixing device. Background Technology

[0002] In the production of ternary precursors, relevant physicochemical indicators are tested throughout the entire process, and the test results are crucial for production process control. When the uniformity and independence of the material samples cannot be effectively guaranteed, data deviations will be reproduced, incorrectly guiding the production process and leading to the production of substandard products. Furthermore, the subsequent investigation of the causes is somewhat concealed, making it a critical issue that must be addressed.

[0003] Currently, most manufacturers rely on manual sampling and subsequent packaging and testing. Because products are produced in batches, they are susceptible to variations caused by system, environmental, and human factors, potentially leading to differences between batches. For precursor manufacturers, ensuring the uniformity and representativeness of sampling typically involves sampling from equal batches or at different time intervals. However, these methods are limited by equipment operating characteristics, making it difficult to achieve uniform material mixing, thus affecting the representativeness of the samples.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0031] Example

[0032] This embodiment provides a mixing device 100. Please refer to [link / reference]. Figure 1The mixing equipment 100 includes a mixing shell 1, an auxiliary mixing roller 2, and an auxiliary mixing device 3.

[0033] The mixing housing 1 has a mixing cavity 101 and is provided with an openable and closable feeding port 102 for communicating with the mixing cavity 101.

[0034] The auxiliary mixing roller 2 is disposed inside the mixing cavity 101 and is connected to the inner wall of the mixing housing 1.

[0035] The auxiliary mixing device 3 is freely movable within the mixing cavity 101.

[0036] By using the openable and closable feeding port 102, materials can be fed into the mixing cavity 101. At the same time, when the mixing shell 1 is flipped, the material impacts the auxiliary mixing roller 2, which can achieve thorough mixing. Combined with the free movement of the auxiliary mixing device 3, the probability of material accumulation in the mixing space is further reduced. Under the dual action of the auxiliary mixing roller 2 and the auxiliary mixing device 3, the material is fully and evenly mixed, which improves the mixing effect and helps to improve the representativeness of the sampling.

[0037] In some alternative embodiments, the mixing housing 1 can be a relatively enclosed housing, thereby preventing the introduction of foreign matter during the mixing process.

[0038] In some alternative embodiments, the mixing shell 1 can be made of stainless steel. In other embodiments, the mixing shell 1 can also be made of other materials. Furthermore, if the strength of the mixing shell 1 is sufficient, it can also be made of transparent or translucent materials.

[0039] In this embodiment, there are multiple auxiliary mixing rollers 2, which are evenly spaced within the mixing cavity 101. Through this method, during the tumbling process of the mixing shell 1, the material can be fully impacted, scattering the mixture as much as possible.

[0040] In some alternative embodiments, one end of the auxiliary mixing roller 2 is connected to the inner wall of the mixing cavity 101, and the other end extends radially along the mixing cavity 101. In some more typical embodiments, the length of the auxiliary mixing roller 2 is set to be less than about half the radius of the mixing cavity 101. This length range ensures that the mixture is dispersed without affecting the normal tumbling of the material.

[0041] In some alternative embodiments, the auxiliary mixing device 3 can be an elastic sphere. Exemplarily, the auxiliary mixing device 3 can be made of rubber or PTFE. For example, when the auxiliary mixing device 3 uses a rubber sphere, the high elasticity of the rubber sphere ensures that the material does not adhere to the inner wall of the mixing cavity 101 and the auxiliary mixing roller 2 during the mixing process.

[0042] In this embodiment, the mixing cavity 101 can be spherical, and the ratio of the diameter of the mixing cavity 101 to the diameter of the auxiliary mixing device 3 is D, where 15 ≤ D ≤ 25. For example, D can be 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, or 25, etc. In some preferred embodiments, D = 20.

[0043] In this embodiment, the mixing device 100 may further include a support platform 4 and a mixing guide rail 5. The mixing guide rail 5 is disposed on the support platform 4, and the mixing housing 1 is disposed on the mixing guide rail 5 in a freely rotatable manner. The above arrangement facilitates the rotation of the entire mixing housing 1.

[0044] To facilitate the rotation of the mixing housing 1, in this embodiment, the mixing device 100 further includes a power source 6, which is mounted on the support platform 4 and is used to drive the mixing housing 1 to rotate on the mixing guide rail 5. The power source 6 can be an electric motor, which outputs power to drive the mixing housing 1 to rotate. Alternatively, a cylinder, hydraulic cylinder, or other power source can be used to achieve the rotation of the mixing housing 1.

[0045] In some alternative embodiments, there are multiple power sources 6, which simultaneously drive the mixing housing 1 to rotate in one direction, such as clockwise or counterclockwise.

[0046] In some alternative embodiments, there are multiple power sources 6, which are used to achieve the mixing and flipping of the mixing shell 1. For example, one power source 6 achieves the rotation of the mixing shell 1 in the XY plane, another power source 6 achieves the rotation of the mixing shell 1 in the XZ plane, and yet another power source 6 achieves the rotation of the mixing shell 1 in the YZ plane.

[0047] To facilitate the loading of materials into the mixing cavity 101, in this embodiment, the mixing equipment 100 further includes a feeding device 7, which is disposed on the top of the support platform 4. The feeding device 7 is used to feed materials into the mixing cavity 101 through the openable and closable feeding port 102.

[0048] In some alternative implementations, the feeding device 7 can be a hopper with a lid on top.

[0049] In practice, the mixing housing 1 can be driven to rotate so that the openable / closable feeding port 102 corresponds to the feeding device 7, and the openable / closable feeding port 102 is opened at the same time. The operator can add material to the openable / closable feeding port 102 through the feeding device 7. After the material is added, the openable / closable feeding port 102 is closed, thereby maintaining the sealing of the mixing housing 1.

[0050] In some alternative implementations, the opening or closing of the feed port 102 can be achieved using a solenoid valve or an electric valve.

[0051] When material needs to be discharged, the mixing housing 1 can be driven to rotate so that the openable and closable feeding port 102 is located at the bottom. After the openable and closable feeding port 102 is opened, the material can be discharged through the openable and closable feeding port 102.

[0052] To facilitate the receiving of mixed materials, in this embodiment, the mixing equipment 100 also includes a discharging device 8, which is disposed at the bottom of the support platform 4. The discharging device 8 is used to receive the material output from the openable and closable feeding port 102. The discharging device 8 can be a closed loading hopper, which can be connected to the support platform 4 at the top via an interface.

[0053] In some alternative implementations, the interface may be made of a flexible material, such as polyvinyl chloride.

[0054] To achieve accurate material feeding, in this embodiment, a metering device 9 is also provided inside the feeding device 8. The metering device 9 is used to measure and output the material within the feeding device 8.

[0055] In some alternative implementations, the metering device 9 can be an electronic platform with mass measurement function commonly found in the prior art. The weight is set according to a program and can be linked with the feeding device 8, stopping feeding once the set weight is reached. For example, a feeding valve can be provided at the bottom of the feeding device 8, and feeding can be stopped by closing the valve.

[0056] The metering principle can be understood as follows: during the material discharge process, the metering device 9 measures the weight of the material in the discharge device 8 in real time. When the reduction in weight reaches the required weight, the discharge valve is closed. This principle is used to meter and output all materials. The metering device 9 can also be connected to an external display screen to show the remaining weight in real time. The metering and discharging equipment can be any of the more mature existing technologies, which will not be elaborated upon here.

[0057] To facilitate material receiving, in this embodiment, the mixing equipment 100 further includes a receiving device 10, which is disposed at the bottom of the discharging device 8 and is used to receive the material output from the discharging device 8. The receiving device 10 can be connected to the discharging device 8 via a connecting pipe, which can be made of a flexible material, such as polyvinyl chloride.

[0058] To facilitate sample preparation, in this embodiment, the mixing equipment 100 also includes a plurality of sample preparation devices 11, which are disposed within the receiving device 10.

[0059] The aforementioned sample distribution device 11 includes a receiving tray and a receiving tube. The receiving tray receives the material output from the discharging device 8. The top of the receiving tube is connected to the receiving tray, and the bottom of the receiving tube is used to connect to the sample bag, thereby enabling the material to be transferred into the sample bag through the receiving tray and the receiving tube.

[0060] In some alternative implementations, the discharge device 8 may have multiple discharge valves, thereby allowing multiple sample dispensing devices 11 to receive the material.

[0061] As described above, the working process of the mixing equipment 100 provided in this embodiment can be found in:

[0062] S1: Take samples from various points on the production line (inside the equipment).

[0063] S2: Control the power source so that the mixing shell 1 rotates to the point where the openable / closeable feeding port 102 connects with the feeding device 7.

[0064] S3: Open the openable and closable feeding port 102 and put the sample into the feeding device 7 so that the sample enters the mixing cavity of the mixing shell 1.

[0065] S4: Close the openable / closable feed port 102 and control the power source to drive the mixing shell 1 to rotate. The rotation deadline can be determined manually or set to automatic control, for example, 4min~7min.

[0066] S5: When the mixing time ends, control the power source so that the mixing shell 1 rotates to align the openable / closeable feeding port 102 with the discharging device 8.

[0067] S6: Open the closable feeding port to allow the material to enter the discharging device 8.

[0068] S7: Control the metering device 9 so that the material is accurately metered and output from the discharge valve of the discharge device 8.

[0069] S8: After preparing the sample bag, align the sample bag with the receiving tube of the sample dispensing device 11 to receive the sample.

[0070] S9: After all the required samples have been collected, the mixing shell 1 can be removed from the support platform 4, the internal samples can be cleaned, and it can be returned to the production line.

[0071] In summary, the mixing equipment 100 provided by this utility model can avoid the introduction of foreign matter during the mixing process, reduce the risk of uneven mixing during manual mixing, and at the same time, reduce physical injury to operators. Utilizing the auxiliary mixing roller 2 and the auxiliary mixing device 3 can significantly reduce powder particle accumulation and adhesion, achieve more precise control of individual sample weight, reduce waste at the powder detection end, and effectively save costs.

[0072] Meanwhile, the mixing equipment 100 can also automatically measure the required sample weight, reducing the cost and waste of sample testing. Unnecessary samples can also be recycled on the production line. It has a good alternative effect in simplifying personnel operation and improving the accuracy of manual measurement. Moreover, the mixing shell 1 is removable from the support platform 4. For example, multiple mixing shells 1 can be used, with different numbers and sizes of auxiliary mixing rollers 2 and auxiliary mixing devices 3 inside. In this way, the corresponding mixing shell 1 can be replaced according to different samples to meet different mixing requirements.

[0073] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
