[0002] In the battery material process, improving the finished product yield of high-nickel products has always been an important direction for cost reduction control, which has a certain impact on the final cost of the battery produced. The traditional method is to store the dehydrated material in a storage device and enter the dryer for drying through a telescopic tube.

The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0044] In related technologies, with the market demand for new energy, battery technology has developed rapidly. In battery material technology, improving the finished product yield of high-nickel products has always been an important direction for cost reduction and control, which has a certain impact on the cost of the final battery produced.

[0045] The traditional method is that the dehydrated material enters the dryer for drying through a telescopic tube. When working, the telescopic tube is extended to dock with the end of the material receiving end of the dryer, and a rubber sealing gasket is set at the end of the telescopic tube to achieve sealed material discharge. After the material discharge is completed, the telescopic tube needs to be retracted to separate the telescopic tube from the dryer. Due to the installation error and processing error of the dryer and the storage device, it is easy to cause parallelism deviation between the docking surface of the telescopic tube and the material receiving end, and the end of the telescopic tube and the end of the material receiving end are uneven. In other words, there is a situation where the compression force acting on the rubber sealing gasket at the docking point of the telescopic tube and the material receiving end is inconsistent, resulting in poor sealing and easy leakage.

[0046] like Figure 1 , Figure 2 and Figure 3 As shown, in order to solve the above-mentioned technical problems, an embodiment of the present application provides a docking device, wherein the docking device 300 includes a telescopic tube 320 and an elastic sealing gasket 330, wherein the telescopic tube 320 has a discharge end 321; the elastic sealing gasket 330 is arranged on the end surface of the discharge end 321, and the elastic sealing gasket 330 has a chamber 331, which extends along the circumference of the elastic sealing gasket 330 and is connected end to end, and the chamber 331 is filled with a flowing medium.

[0047] It is easy to understand that the present application only improves the elastic sealing gasket 330, and the elastic sealing gasket 330 is coaxially fixed to the discharge end 321 of the telescopic tube 320, and then through the telescopic action of the telescopic tube 320, the elastic sealing gasket 330 is driven to contact or detach from the receiving end 410 of the dryer 400, and the material is only discharged after the receiving end 410 completes the docking with the discharge end 321. The elastic sealing gasket 330 seals the gap between the discharge end 321 and the receiving end 410.

[0048] Obviously, the chamber 331 is an annular structure, and the chamber 331 is arranged to be coaxial with the discharge end 321. Since the elastic sealing gasket 330 has the chamber 331, during the docking process, the telescopic tube 320 extends to drive the discharge end 321 close to the receiving end 410, until the discharge end 321 moves to a set position or moves a set distance to squeeze the elastic sealing gasket 330, and then the extrusion force of the discharge end 321 on the elastic sealing gasket 330 is adjusted, so as to achieve the sealing between the discharge end 321 and the receiving end 410; it should be noted that due to the fluidity of the flowing medium, the extrusion force can be evenly dispersed throughout the chamber 331, so that the extrusion force of the elastic sealing gasket 330 at various locations can be basically consistent, thereby ensuring the consistent sealing of the discharge end 321 and the receiving end 410.

[0049] Exemplarily, the elastic sealing gasket 330 is fixed to the end of the discharge end 321 by adhesive bonding, the elastic sealing gasket 330 and the discharge end 321 are coaxially arranged, and the diameter of the inner ring of the elastic sealing gasket 330 is larger than the diameter of the pipe mouth of the discharge end 321, so as to reduce the interference with the discharge of the discharge end 321. Optionally, for those skilled in the art, it is motivated to set the extrusion force so that the elastic sealing gasket 330 can achieve the sealing effect and ensure that the diameter of the inner ring of the elastic sealing gasket 330 after being extruded and deformed is still larger than the diameter of the pipe mouth of the discharge end 321.

[0050] In some embodiments, the elastic sealing gasket 330 is made of elastic materials such as rubber and silicone. Of course, the elastic sealing gasket 330 uses an airbag to fill the airbag with a flowing medium. More specifically, the flowing medium is a liquid medium or a gas medium, wherein the liquid medium can be water, oil, or other mixed liquids, etc.; the gas medium can be oxygen, nitrogen, carbon dioxide, etc.

[0051] By adopting the docking device provided in the present application, a chamber 331 is set in the elastic sealing gasket 330, and a flowing medium is filled into the chamber 331, so that the volume and pressure of the chamber 331 can be adjusted. Due to the fluidity of the flowing medium, when the discharge end 321 of the telescopic tube 320 and the end of the receiving end 410 are docked, the pressure at various locations in the chamber 331 of the elastic sealing gasket 330 can be ensured to be equal. In other words, the clamping force at various locations of the elastic sealing gasket 330 is basically the same, thereby effectively improving the sealing of the docking point between the discharge end 321 and the receiving end 410 of the telescopic tube 320 and reducing the probability of leakage.

[0052] like Figure 3 As shown, in some embodiments, the docking device 300 further includes a pumping member, which is connected to the elastic sealing gasket 330 and communicates with the chamber 331 , and the pumping member can fill and discharge the flowing medium in the chamber 331 .

[0053] That is to say, by providing a pumping device capable of filling and discharging the flow medium in the chamber 331, after the discharge end 321 is connected to the receiving end 410, the discharge device can be used to fill the flow medium into the chamber 331 until the pressure in the chamber 331 reaches a set value, thereby achieving the adjustment of the sealing between the discharge end 321 and the receiving end 410.

[0054] This structural setting is particularly suitable for the scenario where the elastic sealing gasket 330 is worn after long-term use, and the originally set stroke of the discharge end 321 cannot meet the sealing requirements. In other words, due to the wear of the elastic sealing gasket 330, the clamping force acting on the elastic sealing gasket 330 becomes smaller after the discharge end 321 moves to the set position, and the sealing effect cannot be guaranteed. Therefore, the clamping force can be adjusted by filling the chamber 331 with a flowing medium.

[0055] Since the flow medium has different types, the pumping and exhausting parts also have different types accordingly. For example, in some embodiments, the flow medium is a liquid medium, and the pumping and exhausting parts include a pumping and exhausting pump. The inlet of the pumping and exhausting pump is connected to a container storing the liquid medium, and the outlet is connected to the chamber 331. Then, by starting the pumping and exhausting pump, the liquid medium can be filled into the chamber 331, or the liquid medium in the chamber 331 can be discharged. It should be noted that the liquid medium in the chamber 331 can be discharged when the telescopic pipe 320 is retracted, and the weight of the discharge end 321 is reduced, which is beneficial to energy saving and consumption reduction, and can also avoid the elastic sealing gasket 330 from being in an expanded state for a long time, which is beneficial to improving the life of the elastic sealing gasket 330. Specifically, when the liquid medium is selected to be oil or other corrosive liquids, the pumping and exhausting pump is a diaphragm pump.

[0056] For example, in some embodiments, the flowing medium is a gas medium, and the pumping device includes a dual-purpose air pump for charging and discharging. The air pump is used to charge and discharge the gas medium into the chamber 331 to achieve the same technical effect as mentioned above, which will not be repeated here.

[0057] like Figure 3 As shown, in some embodiments, the telescopic tube 320 includes a telescopic tube 323 and a driving portion 322, the telescopic tube 323 has a fixed end and a telescopic end that are relatively arranged; the driving portion 322 is connected to the telescopic end, and under the action of the driving portion 322, the telescopic end can move along the axis of the telescopic tube 323, and the telescopic end forms a discharge end 321.

[0058] The driving part 322 is used to drive the telescopic end to move, so as to realize the telescopic action of the telescopic tube 323. For example, the fixed end is fixedly connected to the stocker 100, and the fixed end is communicated with the discharge port of the stocker 100 to realize the fixation of the fixed end.

[0059] During operation, the driving part 322 drives the telescopic end away from the fixed end to approach the receiving end 410 until the discharge end 321 moves to the set position. When the discharge end 321 moves to the set position, the elastic sealing gasket 330 is clamped between the discharge end 321 and the receiving end 410 to achieve sealing at the joint between the discharge end 321 and the receiving end 410, so that the telescopic tube 323 and the receiving end 410 form a sealed flow channel.

[0060] It is easy to understand that the process in which the driving part 322 drives the telescopic end away from the fixed end is the extension process of the telescopic tube 323 ; the process in which the driving part 322 drives the telescopic end toward the fixed end is the shortening process of the telescopic tube 323 .

[0061] In this embodiment, the driving part 322 includes at least one of an electric push rod, a pneumatic cylinder and a hydraulic cylinder, which is not specifically limited here, as long as it can drive the telescopic end to move along the axial direction of the telescopic tube 323.

[0062] For example, Figure 3 As shown, the driving part 322 is a pneumatic cylinder, the body of the pneumatic cylinder is fixed to the fixed end, and the telescopic rod of the pneumatic cylinder is connected to the telescopic end. When the number of the pneumatic cylinder is one, a plurality of guide rods extending along the axial direction of the telescopic tube 323 can be provided at the fixed end, and the guide rods slide through the slideway of the telescopic end to ensure the stability of the movement of the telescopic end.

[0063] For example, Figure 3 As shown, the telescopic tube 323 includes a fixed tube 3231 and a movable tube 3233, wherein the fixed tube 3231 is connected to the movable tube 3233 via a bellows 3232. The end of the fixed tube 3231 away from the movable tube 3233 forms a fixed end, and the end of the movable tube 3233 away from the fixed tube 3231 forms a telescopic end.

[0064] In order to further improve the sealing performance of the joint, a flange is provided on the end face of the telescopic end, and a flange is provided on the end face of the material receiving end 410 to increase the contact area.

[0065] like Figure 1 As shown, in some embodiments, the telescopic tube 320 further includes a switch valve, which is connected to the telescopic tube 323 , and the switch valve is configured to at least enable the telescopic tube 323 to switch between an on state and a off state.

[0066] It is easy to understand that due to the high moisture content of the material, the telescopic tube 323 is prone to material adhesion residue. Under the influence of time and temperature, the material gradually becomes dry and falls to the surface of the equipment to form dirt, resulting in material loss and causing a large amount of manpower to be invested in cleaning work.

[0067] In order to solve the above problem, the present application installs a switch valve on the telescopic tube 323, for example, installs a switch valve on the upper end or the middle of the telescopic tube 323, so as to realize the function of switching the telescopic tube 323 between the on state and the off state by switching the switch valve. Obviously, after the material is unloaded, the switch valve is controlled to close the telescopic tube 323 to put it in the off state, and then due to the blocking of the switch valve, the material is prevented from dripping, the problem of residual material dripping is solved, the yield of qualified finished materials is improved, and the labor input is reduced.

[0068] It should be noted that the switch valve will be opened only after the discharge end 321 has completed docking with the receiving end 410 .

[0069] like Figure 1 , Figure 2 and Figure 4 As shown, in some embodiments, the switch valve is a plug valve 310, which includes a valve body 311, a plug plate 314 and a scraper 313. The valve body 311 has a valve cavity 312 and a valve path 316. The valve cavity 312 and the telescopic tube 323 are arranged in series. The plug plate 314 is inserted into the valve path 316. The valve path 316 and the valve cavity 312 are connected, and a slot 315 for the plug plate 314 to enter and exit the valve path 316 is formed at the connection between the valve path 316 and the valve cavity 312; the scraper 313 is at least partially installed on the side wall of the valve cavity 312 and close to the slot 315. The scraper 313 has a scraper end, which can contact the plug plate 314 to form a scraper area at the slot 315.

[0070] In this embodiment, the difference from the existing gate valve 310 is the addition of the scraper 313. It is easy to understand that the working principle of the gate valve 310 is: by driving the gate 314 to enter and exit the valve cavity 312 from the slot 315, the valve cavity 312 is opened and closed, corresponding to the opening and closing of the gate valve 310. In this process, since the gate 314 frequently enters and exits the slot 315, if there is material adhered to the gate 314, it will cause the material to enter the valve path 316 and the slot 315, causing the gate 314 to be stuck and worn.

[0071] Therefore, by arranging the scraper portion 313 in the valve cavity 312 and utilizing the contact between the scraper end and the plug plate 314 during the process of inserting and pulling in and out of the slot 315, the material adhered to the scraper can be scraped off, thereby extending the service life of the plug valve 310.

[0072] For example, in the present application, since the material is generally bonded to the upper end of the plug plate 314 , the scraper 313 may be provided only at the position where the valve cavity 312 is located above the plug plate 314 .

[0073] like Figure 4As shown, in one embodiment, the scraping portion 313 includes a scraper connected to the side wall of the valve cavity 312, and the scraper is extended along the circumference of the valve cavity 312 and connected end to end; wherein, one end of the scraper that contacts the plug plate 314 forms a scraping end.

[0074] Obviously, the scraper is an annular structure, and the valve cavity 312 is also an annular structure, and the two are coaxially arranged. Generally, the width of the valve channel 316 is greater than the width of the valve cavity 312, and the formed notch 315 is also annular. Therefore, by setting the scraper as an annular structure, it is possible to prevent materials from entering the valve channel 316.

[0075] In some embodiments, the scraper and the plug plate 314 are both metal parts, and the surfaces of the scraper and the plug plate 314 are both provided with a non-metal layer.

[0076] In this embodiment, the material is a battery material, such as ternary nickel cobalt manganese oxide, nickel cobalt aluminum oxide, lithium iron phosphate, lithium-rich manganese base, lithium cobalt oxide, etc. Due to the characteristics of battery materials, it is necessary to avoid the introduction of metal magnetic foreign matter. In other words, since the scraper and the plug 314 are easily worn parts, the introduction of metal magnetic foreign matter can be prevented by providing a non-metallic layer on their surface.

[0077] For example, the non-metallic layer may be formed by spraying a non-metallic material, with a coating thickness of 0.05 to 0.8 mm.

[0078] In some embodiments, the scraper and the insert plate 314 are both non-metallic parts.

[0079] When the scraper and the plug 314 are non-metallic parts, there is no need to consider the generation of metallic magnetic foreign matter due to wear. For example, the scraper and the plug 314 can be made of PTFE (polytetrafluoroethylene) or PPH (polypropylene homopolymer). The scraper is fixed to the valve body 311 of the plug valve 310 by gluing or hot-melt welding.

[0080] like Figure 5 As shown, the embodiment of the present application further provides a material unloading device, which includes a plurality of docking devices 300 as described in any of the above embodiments;

[0081] At least two stockers 100 are provided, and the stockers 100 can store materials. The stockers 100 have a discharge port, and the telescopic pipe 320 has a feed end, and each feed end is respectively connected to the discharge ports of the at least two stockers 100 .

[0082] Obviously, by connecting the feed end of a telescopic pipe 320 to the discharge ports of multiple storage containers 100, the following conditions can be achieved:

[0083] In the first case, when multiple stockers 100 are loaded with different materials respectively, the unloading of various types of materials can be completed, and the number of telescopic pipes 320 used can be reduced;

[0084] In the second case, when multiple stockers 100 are loaded with the same material, they can be switched to another stocker 100 after one of the stockers 100 is emptied, which can ensure continuous material discharge, save refilling time, and help improve production efficiency.

[0085] For example, each feed end is connected to the discharge ports of two storage devices via a three-way valve 200, thus meeting the requirements of flexible on-site layout.

[0086] Exemplarily, the storage container 100 is configured as one of a centrifuge, a filter press, a vacuum filter, a conveyor, and a silo.

[0087] like Figure 5 As shown, an embodiment of the present application further provides a drying system, the drying system comprising the unloading device described in any of the above embodiments;

[0088] A plurality of dryers 400 are provided, each having a receiving end 410 , which is disposed in the moving path of the discharge end 321 of the telescopic tube 320 and can be docked with the discharge end 321 ; wherein the elastic sealing gasket 330 is clamped between the receiving end 410 and the discharge end 321 .

[0089] That is, by controlling the expansion and contraction of the expansion pipe 320, the material discharging end 321 and the material receiving end 410 can be connected and separated, so that the material in the storage container 100 can be discharged into the dryer 400 for drying. The elastic sealing gasket 330 is used to seal the connection between the material discharging end 321 and the material receiving end 410.

[0090] It should be noted that the material receiving end 410 of the dryer 400 is provided with a feed valve 420 so as to be able to close the material receiving end 410 after the material receiving is completed.

[0091] Exemplarily, the dryer 400 is one of a plowshare dryer, a double cone dryer, a vibration dryer, a microwave dryer, a disc dryer, and a mesh belt dryer.

[0092] In one embodiment, the discharge port of each storage container 100 is connected to the feed ends of at least two telescopic pipes 320 respectively.

[0093] As mentioned above, the requirement of flexible layout on site is met. When a problem occurs in one of the two adjacent dryers 400, the feeding can be maintained in time by switching the telescopic pipe 320, which serve as backup devices for each other, thereby ensuring the complete flexibility of the process without adding equipment.

[0094] In addition, to facilitate understanding of the technical solution of this application, the working principle is provided as follows:

[0095] When the upper storage container 100 has finished storing materials, the storage container 100 is docked to the dryer 400 at the designated position, and the docking device 300 is started to drive the discharge end 321 to move downward to the end of the stroke, and then the chamber 330 of the elastic sealing gasket 330 is inflated to form a closed flow channel with the material receiving end 410 of the dryer 400 to guide the material into the dryer 400; then, the gate valve 310 is started to the passage state, and the scraper scrapes the material on the gate 314 during the movement. , switch the three-way valve to the feed end of the target docking device 300, the stocker 100 starts to discharge the material, and the material falls into the designated dryer 400 through the telescopic tube 323 of the docking device 300.
