Description

Technical Field

[0001] This utility model relates to the field of washing device technology, specifically a washing device for purifying spherical graphite. Background Technology

[0002] Spherical graphite is a spherical graphite material made from natural flake graphite through a series of processing steps. Due to its excellent electrical and thermal conductivity and structural stability, it is widely used as a core raw material for lithium-ion battery anode materials. Purification is a crucial step in the preparation of spherical graphite, aiming to remove acidic reagents, metal ion impurities, and other residues introduced during processing, thereby significantly improving its chemical purity and electrochemical performance. Currently, the purification of spherical graphite often employs a combination of acid washing and water washing. Traditional water washing equipment is mostly simple in structure, typically consisting of a fixed washing container. During operation, the acid-washed graphite is mixed with pure water in the container, and washing is carried out by static soaking or simple mechanical stirring. This method has significant drawbacks: firstly, static soaking is extremely time-consuming and has limited washing effect, making it difficult to completely remove impurities; secondly, simple stirring easily leads to the breakage of graphite particles, affecting their spherical integrity and tap density, and the stirring is also not uniform enough, resulting in washing dead zones. Furthermore, traditional washing equipment has shortcomings in terms of solid-liquid separation and ease of operation. After washing, the entire graphite slurry needs to be transferred to a separate filtration device for dehydration. This process is not only cumbersome and labor-intensive, but also increases material loss and the risk of contamination during the transfer. The loading and unloading of the inner washing tank is often inconvenient, affecting the efficiency of continuous production. Therefore, improvements to existing technology are necessary. Summary of the Invention

[0003] The purpose of this invention is to provide a washing device for purifying spherical graphite, which solves the problems of poor washing effect and low efficiency.

[0008] Preferably, the inside of the lid is movably connected with a screw, which is threaded to the washing tank. The upper end of the spray pipe is fitted with a rotary joint via a bearing, and a water supply hose is fixedly installed on the outside of the rotary joint. External equipment can supply washing water to the inside of the spray pipe through the water supply hose and the rotary joint.

[0009] Preferably, a sealing ring is fixedly installed on the upper part of the inner wall of the washing tank. The sealing ring contacts the tank cover and is located above the drive tub. The sealing ring can seal the connection between the tank cover and the washing tank.

[0010] Preferably, the locking mechanism includes slide rods. Two pairs of symmetrically distributed slide rods are slidably connected inside the drive tub.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model significantly improves the washing effect and ease of operation by organically combining dynamic spraying and synchronous centrifugal filtration. Specifically, the rotating nozzle achieves three-dimensional, uniform spraying without dead angles, while the drive tank drives the washing tub to rotate at high speed, causing the graphite particles to be in a state of violent tumbling, which can fully contact the washing water, instantly washing away and removing impurities from the surface and crevices. At the same time, the embedded filter cloth achieves "wash and filter immediately" under the action of centrifugal force, effectively preventing the secondary adsorption of impurities, and greatly reducing the risk of graphite particle breakage through the gentle tumbling mode. Thus, while ensuring efficient cleaning, it perfectly protects the spherical integrity and tap density of the product.

[0012] 2. This utility model greatly simplifies subsequent operation processes by adopting an integrated and quick-loading / unloading design. It integrates multiple processes such as washing, rinsing, and dehydration into a single sealed device for continuous operation, avoiding the losses and pollution caused by frequent material transfers in traditional processes. The unique spring-return locking mechanism eliminates the need for complex bolt tightening during the loading and unloading of the washing tub; a simple lift and pull is sufficient. This significantly improves production efficiency and reduces labor intensity. This integrated and user-friendly design provides strong guarantees for the continuity, safety, and environmental friendliness of production. Attached Figure Description

A sealing sleeve 10 is fixedly installed on the inner bottom of the washing tank 1. The sealing sleeve 10 is rotatably connected to the drive shaft 3.

The drainage holes 12 can drain water when the raw materials are dehydrated. A bevel gear 17 meshes with a bevel gear disc 15. The bevel gear 17 and the bevel gear disc 15 are located inside the protective cover 16. A reduction motor 18 is fixedly installed on the upper end of the cover 2. The output shaft of the geared motor 18 is fixedly connected to the bevel gear 17. The geared motor 18 can drive the bevel gear disk 15 to rotate through the bevel gear 17. The inside of the cover 2 is movably connected with a screw 21, which is threadedly connected to the washing tank 1. The upper end of the spray pipe 13 is equipped with a rotary joint 19 through a bearing. A water supply hose 20 is fixedly installed on the outside of the rotary joint 19.

The sealing ring 11 can seal the connection between the cover 2 and the washing tank 1.

[0018] Please see Figure 1-7 The locking mechanism 6 includes a slide rod 61. Two pairs of symmetrically distributed slide rods 61 are slidably connected inside the drive tub 4. One end of each pair of slide rods 61 is fixedly connected to a locking frame 62, and the other end of each pair of slide rods 61 is fixedly connected to a handle 63. A spring 64 is provided on the outside of each slide rod 61. The locking frame 62 is slidably connected to both the drive tub 4 and the washing tub 5.

[0019] The specific implementation process of this utility model is as follows: After loading the spherical graphite to be processed into the washing tub 5 and sealing the lid 2, the reduction motor 18 drives the spray pipe 13 and the nozzle 14 to rotate above the washing tub 5 through the meshing of the bevel gear 17 and the bevel gear plate 15, so that the washing water is evenly and three-dimensionally sprayed onto the material. At the same time, the drive motor 9 drives the drive tub 4 to rotate at high speed together with the washing tub 5 through the drive shaft 3, so that the graphite particles in the tub are in a state of violent tumbling, and the rotation direction of the spray pipe 13 is opposite to the direction of the washing tub 5, so as to achieve full contact and efficient rinsing with the spray water flow in all directions and without dead angles. While washing is in progress, the dehydration process begins simultaneously. Under the action of strong centrifugal force, the wastewater generated during washing is quickly passed through the filter cloth 7 on the inner wall of the washing tub 5 and is thrown out through the drain hole 12 at the bottom of the tub to the bottom of the washing tank 1 for unified discharge. This achieves immediate washing and filtration, effectively preventing secondary adsorption of impurities. After the washing program is completed, the operator can pull the handle 63 outward. The handle 63 drives the locking frame 62 to move through the slide rod 61. When the locking frame 62 moves, it engages the spring 64. When the locking frame 62 disengages from the drive tub 4, the locking between the washing tub 5 and the drive tub 4 can be released, and the washing tub 5 containing clean wet material can be lifted out as a whole. This efficiently completes a high-efficiency, closed-loop operation cycle that integrates loading, washing, dehydration, and unloading.
