Description

Technical Field

[0001] This utility model relates to the field of graphite processing technology, and in particular to an isostatic pressing graphite fine powder mixing device. Background Technology

[0002] In the production process of isostatic graphite, the raw material mixing process is a key step to ensure product quality. In particular, the mixing of graphite fine powder requires not only that all raw materials be fully and evenly mixed, but also that the particle size of the graphite powder be strictly screened to remove materials with larger particle sizes, so as to ensure the accuracy of subsequent molding and processing and the performance of the product.

[0003] Currently, traditional isostatic pressing graphite fine powder mixing devices generally employ a horizontally placed filter screen structure when filtering and separating materials. This design has several drawbacks: First, when processing graphite fine powder, the horizontally placed filter screen is prone to clogging due to material accumulation on its surface, leading to a significant decrease in filtration efficiency. This necessitates frequent shutdowns for filter screen cleaning, severely impacting production efficiency. Second, the filtration area of ​​the horizontally placed filter screen is relatively limited, making it difficult to meet the material throughput requirements of large-scale production. Third, during the separation process, the separation effect between larger particle sizes and qualified fine powder is poor, easily resulting in large particle residues or loss of qualified fine powder, leading to unstable product quality and failing to meet the stringent requirements for material consistency and stability in high-end applications.

[0004] To address the aforementioned issues, we propose an isostatic pressing graphite fine powder mixing device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an isostatic pressing graphite fine powder mixing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An isostatic pressing graphite fine powder mixing device includes a static pressure graphite mixing cylinder, a recovery component, and a centrifugal separation component. The static pressure graphite mixing cylinder has a top plate and a bottom plate screwed onto its upper and lower sides, respectively. The centrifugal separation component includes a top motor, the output end of which rotates through to the lower side of the top plate, and a rotating column is fixedly installed below the output end of the top motor. A disc is fixedly installed at the lower end of the rotating column. Four sliding groove plates are fixedly installed at equal intervals on the upper circumference of the disc. A filter plate is slidably installed inside the sliding groove plates. A top limiting ring is screwed onto the top of the four sliding groove plates, and the bottom of the top limiting ring abuts against the upper side of the filter plate.

[0008] Furthermore, a reinforcing block is fixedly connected to the outer wall of the slide plate and the side of the disc.

[0009] Furthermore, the recycling assembly includes a collection box and a three-way pipe. An air pump is connected to the side of the collection box, and an air suction pipe is connected to the top of the collection box. The air suction pipe is connected to the three-way pipe, which is fixedly installed on the upper side of the top plate and its lower end passes through to the lower side of the top plate.

[0010] Furthermore, a corrugated pipe is connected to the lower end of the three-way pipe, and a dust collection hood is connected to the lower end of the corrugated pipe. An electric push rod is fixedly connected between the bottom surface of the top plate and the dust collection hood.

[0011] Furthermore, a dust filter screen is fixedly installed at the connection point between the air pump and the inside of the collection box.

[0012] Furthermore, a bottom motor is fixedly installed at the bottom of the base plate, the output end of the bottom motor rotates through to the upper side of the base plate, and a rotating shaft is fixedly installed on the output end of the bottom motor. A mixing blade is fixedly installed on the side wall of the rotating shaft.

[0013] Furthermore, a feed pipe is fixedly installed on the top plate, and a discharge pipe is fixedly installed on the lower side of the bottom plate. The discharge pipe is connected to the bottom plate at the lowest point of the bottom plate, and a solenoid valve is fixedly installed on both the feed pipe and the discharge pipe.

[0014] Furthermore, a controller is fixedly installed on the side wall of the static pressure graphite mixing cylinder.

[0015] Compared with related technologies, the isostatic pressing graphite fine powder mixing device proposed in this utility model has the following beneficial effects:

[0016] In this invention, an isostatic pressing graphite fine powder mixing device is provided. Through the centrifugal separation component, the combined cylinder of the disc and the surrounding filter plates can be driven to rotate at high speed by starting the top motor. Under the action of centrifugal force, the graphite fine powder will separate from the surrounding filter plates to the outside. The graphite material that does not pass through the filter plates will automatically fall back to the top of the disc after the machine stops, without causing accumulation on the filter surface of the filter plates. Compared with traditional flat screens, it has the advantages of being less prone to clogging and having high filtration and separation efficiency, thereby improving production efficiency. In addition, the filter plates are set around the disc by a sliding insertion limiting method, which makes later maintenance and replacement convenient, further improving the practicality of this invention.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Reference Figures 1-5 A static pressure graphite fine powder mixing device includes a static pressure graphite mixing cylinder 1, a recovery component 5, and a centrifugal separation component 6. The static pressure graphite mixing cylinder 1 is screwed to the upper and lower sides, respectively, with a top plate 2 and a bottom plate 3. The centrifugal separation component 6 includes a top motor 61, the output end of which rotates through to the lower side of the top plate 2, and a rear rotating column 62 is fixedly installed below the output end of the top motor 61. A disc 63 is fixedly installed at the lower end of the rotating column 62. Four sliding groove plates 64 are fixedly installed at equal intervals on the upper circumference of the disc 63. A filter plate 66 is slidably installed inside the sliding groove plates 64. A top limiting ring 67 is screwed to the top of the four sliding groove plates 64. The bottom of the top limiting ring 67 abuts against the upper side of the filter plate 66. A reinforcing block 65 is fixedly connected to the outer wall of the sliding groove plate 64 and the side of the disc 63.

[0025] By setting up the reinforcing block 65 as described above, the connection reliability of the chute plate 64 is enhanced, making the snap-fit ​​support effect of the chute plate 64 on the filter plate 66 more stable.

[0026] In this method, the recycling component 5 includes a collection box 51 and a three-way pipe 54. A vacuum pump 52 is installed on the side of the collection box 51, and a suction pipe 53 is installed on the upper side of the collection box 51. The suction pipe 53 is connected to the three-way pipe 54. The three-way pipe 54 is fixedly installed on the upper side of the top plate 2, and the lower end of the three-way pipe 54 passes through to the lower side of the top plate 2. A corrugated pipe 55 is installed at the lower end of the three-way pipe 54, and a dust hood 56 is installed at the lower end of the corrugated pipe 55. An electric push rod 57 is fixedly connected between the bottom surface of the top plate 2 and the dust hood 56.

[0027] With the above setup, when it is necessary to clean up the larger particles accumulated on the recycling disc 63 after the machine stops, the electric push rod 57 is activated to move the dust hood 56 downwards, closer to the upper side of the disc 63. Subsequently, the air pump 52 is activated to draw air. Under the connection, the dust hood 56 generates an adsorption effect. At the same time, the top motor 61 slowly drives the disc 63 to rotate. Then, under the adsorption effect, the material accumulated on the disc 63 gradually enters the collection box 51 through the dust hood 56, the corrugated pipe 55, the three-way pipe 54, and the suction pipe 53 for storage. Here, the corrugated pipe 55 can adaptively contract and retract with the adjustment of the electric push rod 57.

[0028] In this method, a bottom motor 7 is fixedly installed at the bottom of the bottom plate 3. The output end of the bottom motor 7 rotates through to the upper side of the bottom plate 3, and a rotating shaft 10 is fixedly installed on the output end of the bottom motor 7. A mixing and stirring plate 11 is fixedly installed on the side wall of the rotating shaft 10.

[0029] With the above-mentioned setup, when the bottom motor 7 starts, it can drive the mixing blade 11 to stir in the bottom of the static pressure graphite mixing cylinder 1, and stir and mix the graphite fine powder that falls from the side of the filter plate 66, thereby improving the mixing uniformity of the material.

[0030] In this method, a dust filter screen is fixedly installed at the internal connection between the air pump 52 and the collection box 51.

[0031] By setting up the dust filter as described above, dust is prevented from being sucked into the air pump 52.

[0032] In this method, a feed pipe 9 is fixedly installed on the top plate 2, and a discharge pipe 8 is fixedly installed on the lower side of the bottom plate 3. The discharge pipe 8 is connected to the bottom plate 3 at the lowest point of the bottom plate 3. Solenoid valves are fixedly installed on both the feed pipe 9 and the discharge pipe 8. A controller 4 is fixedly installed on the side wall of the static pressure graphite mixing cylinder 1.

[0033] The working principle of the isostatic pressing graphite fine powder mixing device provided by this utility model is as follows:

[0034] In use, graphite powder raw material is added through the feed pipe 9, and then the solenoid valve on the feed pipe is closed. The top motor 61 is turned on, and its output end drives the rotating column 62 to rotate, thereby causing the disc 63 and the combined cylinder composed of filter plate 66, slide plate 64 and top limiting ring 67 to rotate at high speed. Under centrifugal force, the isostatically pressed graphite powder moves towards the outside of the filter plate 66. The fine powder with the required particle size passes through the mesh of the filter plate 66 and is separated into the space between the inner wall of the statically pressed graphite mixing cylinder 1 and the filter plate 66. The graphite material with a larger particle size that does not pass through the filter plate 66 adheres tightly to the inner side of the filter plate 66 under centrifugal force. When the top motor 61 stops, these large-particle materials automatically fall back to the upper side of the disc 63. At the same time, the bottom motor 7 starts, and the isostatically pressed graphite powder that has passed through the filter plate 66 falls to the bottom of the cylinder. Under the action of the mixing and stirring plate 11, it is fully mixed to ensure that the various raw materials are evenly distributed, improve the uniformity of material mixing, and meet the requirements of the raw material mixing quality for isostatically pressed graphite production. After the mixing is completed, the solenoid valve on the discharge pipe 8 is opened, and the mixed material is discharged. The large-particle material accumulated on the disc 63 is then cleaned and recycled. At this time, the electric push rod 57 is started. The electric push rod 57 extends and drives the dust suction hood 56 to move downward until it approaches the upper side of the disc 63. Then, the suction pump 52 is started. The suction pump 52 forms a suction channel with the dust hood 56 through the suction pipe 53, the three-way pipe 54, and the corrugated pipe 55, so that the dust hood 56 produces an adsorption effect. At the same time, the top motor 61 slowly drives the disc 63 to rotate. Under the action of adsorption force, the large-diameter material accumulated on the disc 63 gradually enters the collection box 51 for storage through the dust hood 56, the corrugated pipe 55, the three-way pipe 54 and the suction pipe 53.
