Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, specifically to a centrifuge splash prevention device. Background Technology

[0002] Centrifuges are widely used in the production of lithium battery materials, such as lithium iron phosphate and lithium cobalt oxide ternary materials, as well as anode materials and graphite-silicon-based materials. They are equipment used to separate and process lithium battery materials. Centrifuges are equipped with a rotating drum with filter holes. The motor makes the drum rotate at high speed to generate centrifugal force, which separates solid particles from liquids, thereby achieving the purpose of purification or recycling.

[0003] When centrifuges separate easily splashable materials such as lithium battery slurry, splashing easily occurs at the feed inlet of the drum due to the rotation of the drum. Simultaneously, during drum rotation, the liquid is thrown out by centrifugal force and collides with the inner wall of the casing, causing splashing onto the top cover and mixing with the material at the feed inlet. Therefore, a centrifuge splash prevention device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a centrifuge splash-proof device to address the aforementioned problems and solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A centrifuge splash prevention device, comprising:

[0006] The housing has an opening at the top, a top cover at the opening, a feed inlet on the top cover, and a discharge outlet at the bottom of the housing.

[0007] The rotating drum is rotatably installed inside the housing and is used for solid-liquid separation of materials. The upper end of the drum wall is provided with an annular baffle plate, and the middle part is the drum discharge port. The feed inlet on the top cover can be opposite to the drum discharge port.

[0008] The anti-splash assembly includes a drum feed anti-splash ring fixed to the inner circumference of the annular baffle plate, an outer anti-splash ring and an inner anti-splash ring fixed to the outer and inner edges of the feed inlet at the lower end of the top cover, and an outer anti-splash ring fixed to the outer circumference of the annular baffle plate. The outer anti-splash ring and the drum feed anti-splash ring are staggered and stacked on top of each other. An annular anti-splash plate is provided at the lower end of the top cover in the gap between the shell and the drum. The annular anti-splash plate, the outer anti-splash ring, and the shell are staggered and stacked on top of each other.

[0009] Furthermore, a rotating shaft liquid-blocking assembly is provided near the discharge port of the housing. The rotating shaft liquid-blocking assembly includes an upper liquid-blocking ring and a lower liquid-blocking ring seat. The upper liquid-blocking ring is located at the bottom of the drum near the discharge port of the housing and extends downward. The lower liquid-blocking ring seat includes a liquid-blocking ring seat body and a lower liquid-blocking ring located on the top outer edge of the liquid-blocking ring seat body and extending upward. The upper liquid-blocking ring and the lower liquid-blocking ring are staggered and fitted together to prevent the liquid separated from the drum from flowing to the rotating shaft of the drum.

[0010] Furthermore, the inner splash guard ring of the top cover includes a first circular ring segment, a flared conical surface segment, and a second circular ring segment arranged sequentially from bottom to top, wherein the cone angle of the flared conical surface segment is 20°-30°.

[0011] Furthermore, the radial gap between the outer anti-splash ring of the top cover and the anti-splash ring of the drum feed is 3-5mm.

[0012] Furthermore, the gap between the annular splash guard and the housing is 3-5 mm.

[0013] By adopting the above technical solution, this utility model has the following beneficial effects:

[0014] This invention prevents material from splashing into the liquid phase region by setting a drum feed anti-splash ring at the drum discharge port, which, together with the outer anti-splash ring and the inner anti-splash ring on the top cover, forms a staggered stacked structure. At the same time, an annular anti-splash plate is set in the gap between the drum and the shell, which, together with the outer anti-splash ring of the drum, forms an anti-splash structure to prevent liquid in the separated liquid phase region from splashing onto the top cover. This double shielding and anti-splashing effectively prevents liquid and material from mixing and coming into contact, resulting in a better anti-splashing effect. Attached Figure Description

[0019] like Figure 1 As shown, a centrifuge splash prevention device includes a housing 1, a drum 2, a splash prevention assembly, and a rotating shaft liquid-blocking assembly 11.

[0020] The shell 1 has an opening at the top, and a top cover 3 is provided at the opening. The top cover 3 has a feed inlet 4, and the bottom of the shell 1 has a discharge outlet 5. The rotating drum 2 is rotatably installed inside the shell 1 and is used for solid-liquid separation of materials. The rotating drum 2 is driven by a motor. When the rotating drum 2 rotates, under the action of centrifugal force, the liquid passes through the filter holes on the wall of the rotating drum 2. The upper end of the wall of the rotating drum 2 is provided with an annular baffle 21, and the middle part is the discharge outlet 22 of the rotating drum. The feed inlet 4 on the top cover 3 can correspond to the discharge outlet 22 of the rotating drum.

[0021] The anti-splash assembly includes a drum feed anti-splash ring 6 fixed to the inner circumference of the annular baffle plate 21, an outer anti-splash ring 8 and an inner anti-splash ring 7 fixed to the outer and inner edges of the feed inlet 4 at the lower end of the top cover 3, and an outer anti-splash ring 9 fixed to the outer circumference of the annular baffle plate 21. The outer anti-splash ring 8 and the drum feed anti-splash ring 6 are staggered and stacked. An annular anti-splash plate 10 is provided at the lower end of the top cover 3 in the gap between the housing 1 and the drum 2. The annular anti-splash plate 10, the outer anti-splash ring 9, and the housing 1 are staggered and stacked.

[0022] To prevent liquid from splashing or flowing into the gap between the bearing housing and the bottom of the drum 2 after separation, a shaft liquid-blocking assembly 11 is provided near the discharge port 5 of the housing 1. The shaft liquid-blocking assembly 11 includes an upper liquid-blocking ring 111 and a lower liquid-blocking ring 113 seat. The upper liquid-blocking ring 111 is located at the bottom of the drum 2 near the discharge port 5 of the housing 1 and extends downward. The lower liquid-blocking ring 113 seat includes a liquid-blocking ring seat body 112 and a lower liquid-blocking ring 113 located on the top outer edge of the liquid-blocking ring seat body 112 and extending upward. The upper liquid-blocking ring 111 and the lower liquid-blocking ring 113 are staggered and fitted together to block the liquid separated from the drum 2 from flowing to the shaft of the drum 2.

[0023] The inner splash guard 7 of the top cover includes a first circular segment, a flared conical segment, and a second circular segment arranged sequentially from bottom to top, with the flared conical segment having a cone angle of 20°-30°. The radial gap between the outer splash guard 8 of the top cover and the drum feed splash guard 6 is 3-5mm. The gap between the annular splash guard 10 and the housing 1 is 3-5mm.

[0024] During use, the material is added through the feed inlet 4 of the top cover 3. The material is prevented from splashing into the liquid phase area by the interlocking structure of the annular baffle 21 of the drum 2, the drum feed anti-splash ring 6, the outer anti-splash ring 8 of the top cover, and the inner anti-splash ring 7. Simultaneously, the outer anti-splash ring 9 of the drum and the annular anti-splash plate 10 at the bottom of the top prevent the liquid from splashing onto the top cover after separation. The separated liquid is discharged from the outlet 5 at the bottom of the housing 1. The rotating shaft baffle assembly 11, consisting of an upper baffle ring 111 and a lower baffle ring 113 seat, located near the outlet 5 at the bottom of the housing 1, effectively blocks the liquid, facilitating its discharge from the outlet 5 and preventing splashing or seeping into the gap between the bearing seat and the bottom of the drum 2 after separation, thus improving the centrifuge's safety. This invention employs double-layer anti-splash protection to prevent liquid from splashing onto the top cover and effectively prevents the liquid from mixing with the material, resulting in better anti-splash performance.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
