[0002] The tap density is an important indicator in the production and manufacturing process of lithium battery positive electrode materials. Therefore, the entire production process of lithium battery positive electrode materials must pay attention to whether the tap density meets the standards, and the detection frequency is relatively high.

[0003] When testing a sample, place the weighed sample into a vibrating graduated cylinder, place it on the base of the vibrating density meter, and vibrate it approximately 3,000 times as required. After the test is completed, pour out the cathode material powder in the cylinder. Currently, the common practice is to remove the cylinder, pour the powder into a material recovery bin, and then clean it with a brush. During this process, a large amount of heavy metal powder will enter the air. Long-term use of this operation can cause damage to personnel health. Using a brush to clean the graduated cylinder will cause wear and tear on the cylinder, affecting the test results.

[0004] In view of this, this application is filed. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0027] Please refer to Figure 1 and Figure 2 The embodiment of the present invention provides a cleaning device 100 for a vibrating measuring cylinder, comprising a sample recovery cylinder 110, a connecting tube 120, a filtering device 130, an exhaust device 140 and a housing 150, wherein the housing 150 is sleeved on the sample recovery cylinder 110.

[0028] One end of the sample recovery cylinder 110 is provided with a mounting port 111, and the mounting port 111 cooperates with the open end of the vibrating measuring cylinder. When in the working state, the vibrating measuring cylinder is inverted at the mounting port 111, so that the material in the vibrating measuring cylinder can fall into the sample recovery cylinder 110. The other end of the sample recovery cylinder 110 is connected to the exhaust device 140 through the connecting pipe 120, and the filter device 130 is detachably connected to the connecting pipe 120. After the material in the vibrating measuring cylinder falls down, the exhaust device 140 can be started to pass the material into the filter device 130 through the connecting pipe to intercept the material and discharge the air. This method avoids a large amount of heavy metal dust from entering the air during manual operation, polluting the laboratory and endangering the health of the operator. The automated device can save operating time and improve efficiency. The use of the exhaust device 140 to extract powder can reduce the impact of the use of a brush on the measuring cylinder.

[0029] Specifically, the exhaust device 140 can be a general exhaust fan, and the specific model is not limited. The filter device 130 can be a general water filter device (such as a conventional water filter vacuum cleaner, which functions like a vacuum filter bottle), the material is precipitated when it encounters water, and the air is discharged through the filter device. The detachable connection of the filter device 130 means that the connecting pipes at the inlet and outlet can be disassembled, and then the filter device 130 can be removed. After the operation is completed, the water filter device can be removed and the material can be cleaned and recycled. Therefore, the cleaning device provided by the embodiment of the utility model can reduce the cleaning time of the measuring cylinder, prevent heavy metal dust from entering the air, reduce the harm to the health of the operator, protect the environment, and save resources.

[0030] Specifically, the connecting pipe 120 may be a general deformable hose, such as a rubber hose.

[0031] In a preferred embodiment, the vibrating measuring cylinder includes a cylinder body and a base located at the end of the cylinder body. The diameter of the mounting port 111 is larger than the diameter of the cylinder body and smaller than the diameter of the base. In this way, the entire cylinder body of the vibrating measuring cylinder enters the sample recovery cylinder 110, and the base is suspended on the mounting port 111, which has a better sealing effect and can better prevent the material from splashing out of the sample recovery cylinder 110.

[0032] In some embodiments, a rubber ring is provided at the mounting opening 111 of the sample recovery cylinder 110. Figure 2 The structure of the rubber ring opening at the mounting port 111 is shown. The rubber ring provides a better seal, further preventing material from splashing out of the sample recovery cylinder 110. A circular rubber ring on top of the rubber ring helps secure the vibrating cylinder. Once the cylinder base is secured, the vibrating cover is placed.

[0033] In some embodiments, the bottom of the sample recovery cylinder 110 is conical, with an inner diameter gradually decreasing from one end close to the installation opening 111 to the other end. The conical shape of the sample recovery cylinder 110 makes it easier for the material to fall downward into the connecting tube 120.

[0034] In some embodiments, the housing 150 has a removable cover with a vibrating device 151 mounted thereon. The main body of the housing 150 is cylindrical, with a larger diameter than the sample recovery cylinder 110. In operation, the cover fits over the top of the housing 150, and the vibrating device 151 acts on the base of the vibrating graduated cylinder. The sample recovery cylinder 110 with the housing 150 ensures a sealed environment during the experiment, preventing dust from being generated during the vibration of the material and causing environmental pollution. The vibrating device 151 vibrates the vibrating graduated cylinder, allowing the material to fall more quickly into the connecting tube 120.

[0035] In some embodiments, the vibration device 151 includes a silicone head (not shown) and a motor for driving the silicone head to move back and forth. The motor drives the silicone head to move back and forth up and down, hitting the bottom of the measuring cylinder so that the material in the measuring cylinder becomes loose during the vibration and naturally falls into the sample recovery cylinder 110, and is collected in the connecting tube 120 from the bottom of the slope.

[0036] Specifically, the motor can be a conventional driving mechanism, and the specific model is not limited. It can include structures such as bearings, eccentric wheels and connecting rods. The motor drives the bearings to rotate and drives the eccentric wheels and connecting rods to reciprocate. A silicone head is installed at one end of the connecting rod.

[0037] In another embodiment, the housing 150 may not be provided, and the bottom of the vibrating cylinder may be vibrated by an external device. The detachable connection between the cover and the main body of the housing 150 is not limited. The detachable connection between the cover and the main body may be achieved by providing protrusions and grooves on the two parts, or by fixing them with a fixing member.

[0038] Furthermore, when in operation, the cover of housing 150 is mounted on the top of housing 150, with the silicone head aligned with the base of the vibrating graduated cylinder. This allows the vibrating silicone head to be perpendicular to the center of the graduated cylinder base. After activating the vibrating device 151, the silicone head continuously strikes the graduated cylinder base, causing the material in the graduated cylinder to loosen and fall along the conical edge into the connecting tube 120 below the sample recovery cylinder 110. After vibration is complete, the exhaust fan is activated, allowing the material to enter the water filtration device, where the material dust settles in the water. The remaining air is then discharged after passing through the filter. The material in the water filtration device can be collected and recycled.

[0039] In some embodiments, the cleaning device may be made of nylon, which is made of polyamide fiber (nylon) material, which can not only ensure mechanical strength requirements, but also have the advantages of a smooth surface, non-sticky materials, and corrosion resistance.

[0040] It should be noted that the steps for using the cleaning device provided by the present invention are as follows: first, open the cover of the housing 150 and place the tested graduated cylinder upside down on the mounting opening 111. The graduated cylinder is fixed vertically by the rubber ring around the hole. The cover of the housing 150 is closed and fastened. The rotary motor is turned on, driving the silicone head to move up and down, striking the bottom of the graduated cylinder to compact the material in the graduated cylinder. The material in the cylinder becomes loose due to the vibration and naturally falls into the sample recovery cylinder 110. The material is collected by the bottom of the inclined surface into the connecting pipe 120. The exhaust device 140 is activated to draw the material in the connecting pipe 120 into the water filter device. The material precipitates when it encounters water, and the air is discharged through the filter device. The water filter device is removed and the recovered material is cleaned.

[0041] An embodiment of the present invention provides a tap density detection device, including a cleaning device provided in the embodiment of the present invention. By introducing the cleaning device, the material in the tapped measuring cylinder can be better processed. By automatically cleaning and recovering the powder in a closed environment, dust pollution caused by the material during vibration can be avoided. The operation time can also be reduced, the health of the operator can be protected, the environment can be protected, and resources can be saved.

[0042] In some embodiments, the tap density detection device further includes a tap measuring cylinder and a tap density meter. The tap measuring cylinder may be an existing measuring cylinder used to measure tap density, and the tap density meter may be an existing instrument used to measure the density of powder or particles after tapping.

[0043] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0044] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
