Description

Technical Field

[0001] The utility model relates to the technical field of lithium chip treatment, in particular to a silicone oil lithium chip removal device. Background Technique

[0002] Lithium is a silver-white metal, which is solid at normal temperature and pressure. It has characteristics such as low density, high electrical conductivity and high thermal conductivity. Lithium has a wide range of applications in the industrial and technological fields. The most common application is as the main material of the battery in lithium-ion batteries. Lithium-ion batteries are widely used in fields such as electric vehicles and mobile electronic devices due to their advantages such as high energy density, light weight and long life.

[0003] During the processing of lithium metal, lithium chips are often accompanied. If tiny lithium chips are inhaled into the body, it will cause serious harm to health. Therefore, a lithium chip removal device needs to be configured during the processing. However, lithium is a highly reactive metal and can quickly undergo chemical reactions in air and water, generating flammable and explosive gases such as hydrogen. Therefore, when the traditional exhaust system with a filter is used to process lithium chips, there are still certain safety hazards. Content of the Utility Model

[0004] The purpose of the utility model is to provide a silicone oil lithium chip removal device with high safety.

[0005] To achieve the above purpose, the technical solution of the utility model is as follows.

[0006] A silicone oil lithium chip removal device includes a machine body. A dust settling box is installed at the top inside the machine body, and a silicone oil tank is installed at the bottom inside the machine body. The silicone oil tank is connected to the dust settling box through a connecting pipe, and a first butterfly valve is arranged inside the connecting pipe. An oil pump is installed on the outer surface of the silicone oil tank. The input end of the oil pump is connected with an oil suction pipe, and the end of the oil suction pipe penetrates into the inside of the silicone oil tank. A spray pipe is installed inside the dust settling box, and the output end of the oil pump is connected with the spray pipe through an oil outlet pipe. A first filter screen is arranged inside the silicone oil tank. An air inlet pipe is installed on the outer surface of the machine body, and the air inlet pipe is connected to the dust settling box, and a second butterfly valve is arranged inside the air inlet pipe. A cylinder is installed on the upper surface of the silicone oil tank. An extrusion filter plate is arranged inside the silicone oil tank, and the end of the telescopic end of the cylinder is connected to the extrusion filter plate. The lower end of the connecting pipe is connected with a filter cloth bag, and the filter cloth bag is arranged on the upper surface of the extrusion filter plate.

[0007] It can be seen that the silicone oil ejected from the spray pipe can sediment the lithium chips in the air. After the silicone oil containing lithium chips falls into the filter cloth bag, the first butterfly valve is closed, and the air cylinder is started to drive the extrusion filter plate to squeeze the filter cloth bag upward. The oil liquid seeps out of the filter cloth bag and falls on the first filter screen for secondary filtration, and finally falls to the bottom of the silicone oil tank, and is then pumped back into the oil pump by the oil suction pipe for recycling. Thus, the lithium chips can be collected in the filter cloth bag, and the silicone oil falling to the bottom of the silicone oil tank has a high purity, reducing other impacts such as clogging of the oil pump and spray pipe, and ensuring the effect of removing lithium chips. Since the silicone oil has certain fire extinguishing and heat insulation properties, it can effectively prevent the lithium chips from contacting with the oxygen in the air, so the possibility of lithium chip combustion and explosion can be reduced, and the safety is high.

[0008] Furthermore, a second filter screen is installed near the upper side inside the dust settling box.

[0009] After the air containing lithium chips is sucked into the dust settling box by the negative pressure device, the air flows upward and passes through the second filter screen. If there are residual lithium chips in the air, they can be filtered by the second filter screen to prevent the lithium chips from entering the subsequent negative pressure device and affecting the use of the negative pressure device.

[0010] Furthermore, a placement box is installed on the outer surface of the machine body, and a fluoride salt fire extinguisher is arranged inside the placement box.

[0011] By configuring the fluoride salt fire extinguisher, intervention can be carried out in a timely manner in case of combustion, ensuring the safety of on-site operations.

[0012] Furthermore, the number of air cylinders is four, and the four air cylinders are respectively arranged at the four corners of the upper surface of the silicone oil tank.

[0013] The telescopic ends of the four air cylinders are respectively connected to the four top corners of the extrusion filter plate, making the overall force on the extrusion filter plate more uniform, not only with a firm structure, but also with a better extrusion effect on the filter cloth bag.

[0014] Furthermore, both the first filter screen and the second filter screen are made of stainless steel, and the mesh number of both the first filter screen and the second filter screen is 800 mesh.

[0015] Stainless steel has good corrosion resistance, which can improve the service life of the first filter screen and the second filter screen. And the mesh number of the first filter screen and the second filter screen is 800 mesh, which has a high filtration accuracy and can achieve a good filtration effect on lithium chips.

Specific embodiments

[0020] The present utility model will be described in detail below with reference to the accompanying drawings.

[0021] As Figures 1-3 shown, a device for removing lithium chips from silicone oil includes a machine body 100. A dust settling box 102 is installed at the top inside the machine body 100, and a silicone oil tank 103 is installed at the bottom inside the machine body 100. The silicone oil tank 103 is connected to the dust settling box 102 through a connecting pipe 104, and a first butterfly valve 105 is arranged inside the connecting pipe 104. An oil pump 107 is installed on the outer surface of the silicone oil tank 103. The input end of the oil pump 107 is connected with an oil suction pipe 108, and the end of the oil suction pipe 108 penetrates into the inside of the silicone oil tank 103. A spray pipe 109 is installed inside the dust settling box 102, and the output end of the oil pump 107 is connected with the spray pipe 109 through an oil outlet pipe 111. A first filter screen 110 is arranged inside the silicone oil tank 103. An air inlet pipe 101 is installed on the outer surface of the machine body 100, and the air inlet pipe 101 is connected with the dust settling box 102, and a second butterfly valve 106 is arranged inside the air inlet pipe 101. A cylinder 200 is installed on the upper surface of the silicone oil tank 103. An extrusion filter plate 201 is arranged inside the silicone oil tank 103, and the end of the telescopic end of the cylinder 200 is connected with the extrusion filter plate 201. The lower end of the connecting pipe 104 is connected with a filter cloth bag, and the filter cloth bag is arranged on the upper surface of the extrusion filter plate 201.

[0022] During use, first connect the air inlet pipe 101 to the dust suction pipe, then close the first butterfly valve 105, open the second butterfly valve 106, and start the oil pump 107. The oil pump 107 extracts the silicone oil at the bottom of the silicone oil tank 103 through the oil suction pipe 108 and sprays it into the dust settling tank 102 through the spray pipe 109. Subsequently, start the negative pressure device. Under the action of negative pressure, the air with lithium chips enters the dust settling tank 102 from the air inlet pipe 101. The sprayed silicone oil can sediment the lithium chips in the air, causing the silicone oil and lithium chips to mix and deposit at the bottom of the dust settling tank 102. Then open the first butterfly valve 105, and the silicone oil containing lithium chips falls into the filter bag installed at the lower end of the connecting pipe 104. Next, close the first butterfly valve 105, start the cylinder 200 to drive the extrusion filter plate 201 to squeeze the filter bag upward. The oil liquid oozing out of the filter bag falls on the first filter screen 110 through the mesh holes of the extrusion filter plate 201 for secondary filtration, and finally falls to the bottom of the silicone oil tank 103 and is pumped back into the oil pump 107 by the oil suction pipe 108 for recycling. Thus, the lithium chips can be collected in the filter bag, and the silicone oil falling to the bottom of the silicone oil tank 103 has a high purity, reducing other impacts such as clogging of the oil pump 107 and the spray pipe 109, and ensuring the effect of removing lithium chips.

[0023] Specifically, a second filter screen 300 is installed near the upper side inside the dust settling tank 102. After the air containing lithium chips is sucked into the dust settling tank 102 by the negative pressure device, the air flows upward and passes through the second filter screen 300. If there are residual lithium chips in the air, they can be filtered by the second filter screen 300 to prevent the lithium chips from entering the subsequent negative pressure device and affecting the use of the negative pressure device.

[0024] Specifically, a placement box 400 is installed on the outer surface of the machine body 100, and a fluoride fire extinguisher 401 is arranged inside the placement box 400. By configuring the fluoride fire extinguisher 401, timely intervention can be carried out in case of a combustion situation to ensure the safety of on-site operations.

[0025] Specifically, the number of cylinders 200 is four. The four cylinders 200 are respectively arranged at the four corners of the upper surface of the silicone oil tank 103, and the telescopic ends of the four cylinders 200 are respectively connected to the four top corners of the extrusion filter plate 201, making the overall force on the extrusion filter plate 201 more uniform. It is not only structurally firm but also has a better extrusion effect on the filter bag.

[0026] Specifically, both the first filter screen 110 and the second filter screen 300 are made of stainless steel, and the mesh number of both the first filter screen 110 and the second filter screen 300 is 800 meshes. Stainless steel has good corrosion resistance, which can extend the service life of the first filter screen 110 and the second filter screen 300. Moreover, the mesh number of the first filter screen 110 and the second filter screen 300 is 800 meshes, which has a high filtration accuracy and can achieve a good filtration effect on lithium chips.

[0027] The above is a detailed description of the present utility model in combination with specific embodiments. It cannot be determined that the specific implementation manners of the present utility model are only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model pertains, without departing from the concept of the present utility model, making several equivalent substitutions or obvious modifications, and having the same performance or use, all should be regarded as belonging to the patent protection scope determined by the claims submitted for the present utility model.
