Description

Technical Field

[0001] The utility model relates to the technical field of positive electrode material production, and in particular to a copper element control mechanism for a positive electrode material production workshop. Background Art

[0002] The high copper content causes copper to accumulate on the negative electrode side of the lithium-ion battery, forming copper dendrites that pierce the diaphragm, thereby reducing the cycle life of the battery. In severe cases, it can cause the battery to short circuit, causing the battery to lose control and catch fire, posing a huge safety hazard.

[0003] Unlike magnetic metal particles, copper is not magnetic and cannot be removed by an iron remover. Therefore, once copper is introduced into battery materials, there is a lack of effective means to remove it. Based on this, the control of copper-containing components in the workshop is the key task of the positive electrode material factory. Among them, copper components are replaced with copper-free materials as much as possible. Generally, a large number of motors are used in production workshops, including pumps, fans, rotary valves, etc., and the coils of the motors are made of copper and cannot be replaced by other materials. Copper particles will inevitably be generated during operation, scattered in the workshop environment and introduced into the positive electrode material. In addition, the motor needs to dissipate heat during operation. If the motor is sealed to isolate the copper, it will cause the motor to overheat and shut down. Utility Model Content

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] In order to solve the technical problem in the prior art that a large number of motors are used in the positive electrode material production workshop, and the coils of the motors are made of copper, a large number of copper particles will be generated during operation, and these copper particles will be scattered into the workshop environment and introduced into the positive electrode material, the utility model provides a copper particle control mechanism for the positive electrode material production workshop, which can lead the copper particle out of the positive electrode material production workshop and filter and recover it.

[0020] See also Figure 1 , Figure 1 A copper element control mechanism for a positive electrode material production workshop in one embodiment of the utility model is used to prevent the copper element generated during the operation of each motor 1 in the positive electrode material production workshop 8 from being introduced into the positive electrode material. The mechanism comprises a plurality of protective covers 2, a precision filter 14 and an exhaust member. The plurality of protective covers 2 are arranged in the positive electrode material production workshop 8, and each of the protective covers 2 is respectively arranged on the outside of each motor 1. A plurality of air vents 4 are provided on each of the protective covers 2. The precision filter 14 and the exhaust member are both arranged outside the positive electrode material production workshop 8. The air outlet end of the exhaust member is connected to the precision filter 14, and the air inlet end of the exhaust member is respectively connected to the plurality of protective covers 2 via a plurality of branches 7.

[0021] On the basis of the above scheme, a temperature sensor 5 is installed on the protective cover 2 to detect the internal temperature of the protective cover 2 to ensure the heat dissipation effect of the motor and prevent the motor in the protective cover 2 from burning out due to excessive operating temperature.

[0022] On the basis of the above scheme, a sticky dust pad 3 is provided at the inner bottom of the protective cover 2, and the sticky dust pad is used to adhere to the copper element with a larger particle size. Specifically, an adhesive layer is provided on the sticky dust pad 3, and the copper element with a larger particle size can adhere to the sticky dust pad 3. Only by replacing the sticky dust pad 3, the copper element with a larger particle size in the protective cover 2 can be cleaned.

[0023] On the basis of the above solution, a first control valve 6 is provided on each of the plurality of branches 7 , and when one of the motors is not working, the branch can be closed by the corresponding first control valve 6 .

[0024] In this specific embodiment, the air extraction member includes two induced draft fans 10 arranged in parallel on the main road, and the air inlet end and the air outlet end of the two induced draft fans are respectively provided with a second control valve 9 and a third control valve 11. It should be noted that one induced draft fan 10 is a standby fan, and the other induced draft fan 10 is a common fan. When any one of the induced draft fans 10 is damaged, the other induced draft fan 10 can be turned on to ensure the normal operation of the mechanism.

[0025] In this specific embodiment, the air inlet and outlet ends of the precision filter 14 are respectively provided with a fourth control valve 13. The precision filter 14 is a three-stage precision filter. It should be noted that the three-stage precision filter is a device for filtering impurities in the gas. It is usually composed of three filters with different precisions, which can effectively remove tiny particles, suspended matter, microorganisms and other impurities, thereby improving the purity and quality of the gas. The filtering precision of the three-stage precision filter is 10μm, 1μm and 0.01μm. The precision filter 14 can intercept the copper element particles brought out by the induced draft fan to prevent the copper element from being scattered in the environment.

[0026] On the basis of the above scheme, a differential pressure gauge 12 is connected between the air inlet and outlet ends of the precision filter 14. It should be noted that the differential pressure detector 12 is used to detect the pressure difference before and after the precision filter 14. If the pressure is too high, it means that the filter is clogged and needs to be cleaned.

[0027] On the basis of the above scheme, a bypass pipeline is further connected between the air inlet and the air outlet of the precision filter 14, and the bypass pipeline is provided with a fifth control valve 15. When the precision filter 14 needs to be cleaned, the fourth control valve 13 can be closed and the fifth control valve 15 can be opened, so that the air flow can flow through the bypass pipeline.

[0029] In order to better understand the present invention, the following Figure 1 The technical solution of the utility model is described in detail: by arranging multiple protective covers 2 in the positive electrode material production workshop 8, and each protective cover 2 is respectively covered on the outside of each motor 1, the precision filter 14 and the exhaust component are both arranged outside the positive electrode material production workshop 8, and each protective cover 2 is evacuated by the exhaust component, so that the copper element generated when the motor is running can be pumped to the precision filter 14, and the precision filter 14 can filter out the copper element in the airflow.
