Description

Technical Field

[0001] This utility model relates to the field of graphite ink separation and dehydration technology, and in particular to a graphite ink separation and dehydration device. Background Technology

[0002] Graphite, as a strategic mineral resource, is widely used in lithium-ion battery anodes, refractory materials, and the nuclear industry. Its purity, moisture content, and physical properties directly affect product performance. Water separation and dewatering are core steps in graphite purification and processing, playing a decisive role in product quality, energy consumption, and environmental compliance. Graphite ore needs to be crushed, ground, and flotated to obtain concentrate. However, the water content of the graphite slurry after flotation is as high as 70%-80%, requiring efficient dewatering to meet the requirements of subsequent processing (such as spheroidization, coating, and calcination). Traditional dewatering technologies (such as natural sedimentation and plate and frame filter presses) suffer from low efficiency and the risk of metal contamination. With the surging demand for high-purity graphite (such as anode materials with Fe content <50ppm) from the new energy industry, the industry urgently needs intelligent and low-pollution dewatering solutions.

[0003] Chinese patent application number "2023235879324" discloses a graphite purification and dehydration device. It uses a stirring motor to drive a stirring plate to agitate the washing liquid, enhancing the washing effect on graphite and improving washing efficiency. A ventilation motor and an electric heating ring are activated; the ventilation motor drives the fan blades to generate a high-speed airflow, which is then heated by the electric heating ring. However, in actual production, this dehydration device exhibits many technical defects. In particular, the filter sleeve has a fixed aperture structure, making it prone to clogging by fine graphite particles, requiring frequent disassembly and cleaning. This necessitates the disassembly of the reset spring and electromagnet, affecting continuous production. Most importantly, the drying component uses an electric heating ring combined with a ventilation motor for air blowing, which has limited dehydration effect on fine graphite (e.g., -325 mesh) and consumes a lot of energy. Utility Model Content

[0024] The following is an example:

[0025] like Figure 1 , Figure 2The illustrated graphite ink separation and dehydration device includes a dehydration tank 100, a top cover 200 hinged to the dehydration tank 100, a transmission chamber 300 welded below the dehydration tank 100, and a water storage tank 400 fixed below the transmission chamber 300 by bolts. A dehumidification fan 210 is installed inside the top cover 200, with its motor vertically downwards mounted on top of the cover 200. A stirring device 500 is installed at the bottom of the dehydration tank 100, and its transmission mechanism is installed inside the transmission chamber 300. The water storage tank 400 contains a water storage device 410 and a heating pump device 420. The water storage device 410 and the heating pump device 420 are connected... A drying tank 600 is installed above the stirring device 500. Liquid supply channels 610 are evenly distributed inside the side wall of the drying tank 600, forming a water bath heating structure. A water inlet 620 and a water outlet 630 are provided on one side of the drying tank 600. The water outlet 630 of the drying tank 600 is connected to the water storage device 410, and the water inlet 620 of the drying tank 600 is connected to the heating pump device 420. The drying tank 600 and the heating pump device 420 are connected by a conduit. A lifting device 700 is installed on one side of the dehydration tank 100 through a mounting bracket. The lifting device 700 is connected to the drying tank 600 to control the lifting of the drying tank 600.

[0026] Specifically, such as Figure 6An adapter 800 is threadedly connected to the conduit between the drying tank 600 and the heating pump device 420. Both the heating pump device 420 and the water storage device 410 are connected to the adapter 800 via flexible pipes 820. The drying tank 600 is connected to the adapter 800 via rigid pipes 810. The rigid pipe 810 connected to the water inlet 620 is the water inlet rigid pipe, and the rigid pipe 810 connected to the water outlet 630 is the water outlet rigid pipe. The flexible pipe 820 connected to the water inlet rigid pipe via the adapter 800 is the water inlet flexible pipe, and the flexible pipe 820 connected to the water outlet rigid pipe via the adapter 800 is the water outlet flexible pipe. The lengths of the two flexible tubes 820 are both greater than the length of the flexible tube 820 in the tensioned state when the adapter 800 is at the limit height of the lifting device. The stirring device 500 includes a second drive unit 510 located outside the dehydration tank 100, a turbine fan blade 520 located at the bottom of the dehydration tank 100, and a synchronous belt drive mechanism 530 located between the second drive unit 510 and the turbine fan blade 520. The synchronous belt drive mechanism 530 is located inside the transmission chamber 300. The driving pulley of the synchronous belt drive mechanism 530 is connected to the output end of the second drive unit 510, and the driven pulley of the synchronous belt drive mechanism 530 is connected to the turbine fan blade. Leaf 520 is connected via the same pivot. Lifting device 700 includes a first drive unit 710 located on one side of dehydration tank 100, a lead screw 720 located above the first drive unit 710, and a nut mounting block 730 slidably connected to the lead screw 720. The lead screw 720 is vertically mounted on one side of dehydration tank 100 and connected to the output end of the first drive unit 710. The nut mounting block 730 is connected to an adapter 800. The drying tank 600 is preferably made of ceramic material. The water storage device 410 is a water tank with an inlet and an outlet. The heating pump device 420 is an integrated heating pump. 0 is connected to the water collection and heating tank of the heating pump device 420 through a water supply pipe. The specific structure is consistent with the integrated heating pump structure of the washing equipment used in the laundry plant. In the actual assembly of this dehydration equipment, the size of the integrated heating pump can be adjusted according to actual needs. The first drive unit 710 is a stepper motor with model number 57HS11-0904S, and the second drive unit 510 is a three-phase asynchronous motor with model number Y2-132M-4. The synchronous belt drive mechanism 530 is a meshing belt drive mechanism, which is a well-known technology in the field of transmission. The structure of the synchronous belt drive mechanism 530 will not be described in detail here.

[0027] In addition, in the actual design and assembly work, the top cover of the dehydration device is locked to the dehydration tank body by at least one locking structure. This locking structure is consistent with the metal buckle structure of the truck side panel. The buckle structure is a well-known technology and will not be described in detail here. At the same time, the dehydration device is equipped with a control unit. The first drive unit 710, the second drive unit 510 and the dehumidification fan 210 are electrically connected to the control unit, integrating the dehydration and drying functions together. The dehydration tank body 100 can perform preliminary water selection and dehydration of graphite, while the drying tank 600 further dries the dehydrated graphite. This integrated design reduces the transfer in the production process, improves production efficiency, and also reduces the graphite loss and pollution risk caused by multiple transfers.

[0028] Furthermore, the drying tank 600 of this dehydration device adopts a water bath heating structure. Therefore, hot water is circulated to the liquid supply channel 610 of the drying tank 600 through the heating pump device 420, so that the graphite is heated evenly. Compared with traditional hot air drying and other methods, water bath heating can provide a more stable and uniform temperature field, avoid the problem of graphite quality degradation caused by local overheating, and help improve the quality stability of graphite products.

[0029] Meanwhile, during the drying stage, the drying tank 600 is adjusted to a position where it is in full contact with the graphite using the lifting device 700. After the washing liquid is discharged, the graphite precipitated in the drying tank 600 is heated to ensure the heating effect. This flexible position control method can be adjusted according to different production stages, improving the applicability and functionality of the device.

[0030] As a further technical solution in this embodiment, such as Figure 1 The water storage device 410 and the dehydration tank 100 shown are both connected to an external water supply device for supplying water to the water storage device 410 and the dehydration tank 100.

[0031] In addition, the dehydration tank 100 is connected to an external sewage treatment device via a water supply pipe, and a solenoid valve 900 is installed on the water supply pipe to control the discharge of washing liquid from the dehydration tank 100.

[0032] An external water supply device injects water into the water storage device 420. The water then enters the water collection and heating tank within the heating pump device 420 for heating. The high-temperature water is pumped sequentially through a flexible inlet pipe, an adapter 800, and a rigid inlet pipe into the liquid supply channel 610 of the drying tank 600. After the drying tank 600 dries the graphite, the high-temperature water in the drying tank 600 returns to the water storage device 420 sequentially through the outlet 630, the rigid outlet pipe, the adapter 800, and the flexible outlet pipe. The water storage device 410 and the heating pump device 420 within the water storage tank 400 work together to achieve the recycling of water resources. The outlet 630 of the drying tank 600 is connected to the water storage device 410, allowing the hot water to flow back to the water storage device 410 after completing one heating cycle. After reheating, the water can be reused, reducing water waste and conforming to the development trend of energy conservation and environmental protection.

[0033] As a further technical solution in this embodiment, such as Figure 4 , Figure 6 The drying tank 600 shown is provided with a limiting slide 640 on the side opposite to the lifting device 700. The limiting slide 640 is provided with several sliding holes. The dehydration tank 100 is provided with an installation platform 110 at the upper part corresponding to the position of the limiting slide 640. The installation platform 110 is provided with several limiting rods 120 that pass through the sliding holes. The bottom end of the limiting rods 120 is connected to a limiting baffle 130.

[0034] As a further technical solution in this embodiment, such as Figure 1 An electromagnetic valve 900 is provided on the connecting pipeline between the dehydration tank 100 and the external water supply device to control the on / off of the pipeline supplying water to the dehydration tank 100.

[0035] As a further technical solution in this embodiment, such as Figure 3 The upper cover 200 shown has a dehumidification vent 210 on its side wall. A fresh air inlet 220 is provided on the side wall of the upper cover 200 at the position corresponding to the dehumidification vent 210. A dehumidification duct 230 is provided on one side of the dehumidification fan 210. The dehumidification duct 230 is connected to the dehumidification vent 210. The fresh air inlet 220 is connected to the inner cavity of the dehydration tank 100 through the fresh air duct 240. Both the dehumidification duct 230 and the fresh air duct 240 are located inside the upper cover 200.

[0036] Both the exhaust vent 210 and the fresh air vent 220 are equipped with dustproof net structures. The installation of the dustproof net structure is consistent with the dustproof net installation structure of the air outlet and fresh air vent of the known fresh air system, and will not be described in detail here. The upper cover 200 is equipped with an exhaust fan 210. Through the design of the exhaust duct 230 and the fresh air duct 240, air circulation is realized in the dehydration tank 100. The exhaust fan 210 can timely exhaust the moisture in the tank and introduce fresh air at the same time, which accelerates the drying process of graphite and improves the drying efficiency.
