Description

Technical Field

[0001] This utility model relates to the technical field of battery material screening equipment, and in particular to a material buffer device on a dust cover of a vibrating screen and a vibrating screen. Background Technology

[0002] Battery material vibrating screens are mainly used for screening positive and negative electrode materials in batteries, such as artificial graphite, graphene, lithium cobalt oxide, lithium iron phosphate, and hard carbon. Employing an ultrasonic screening system, it effectively prevents easily agglomerated, oily, and adhesive battery materials from clogging the screen. By classifying battery material powders of different particle sizes, it controls the different particle sizes of the battery materials.

[0003] In practical applications, for vibrating screens with a diameter of 1m or more, the feed pipe is generally DN200. During the feeding process, the material flowing into the screen is very concentrated, and the powder is concentrated on the screen inside the screen, which increases the pressure on the screen. During the production process, the material impacts the screen for a long time, which greatly reduces the service life of the screen.

[0004] In the current production process, using appropriate screen tension during screen manufacturing extends the service life of the screen. The above solutions, which only optimize screen tension, cannot fundamentally alleviate the impact problem. The screen tension will decay rapidly, shortening its lifespan. Utility Model Content

[0005] To address the aforementioned problems, this utility model aims to propose a material buffering device on a dust cover for a vibrating screen and a vibrating screen in general. By installing a disc with diversion holes at the feed inlet of the vibrating screen to buffer the material, the impact force of the material on the screen mesh is reduced, effectively improving the service life of the screen mesh.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A material buffer device on a dust cover of a vibrating screen includes:

[0008] The disc has a diameter that matches the feed inlet diameter of the vibrating screen;

[0009] Several diversion holes are formed on the disc;

[0010] A detachable suspension assembly is used to secure the disc to the dust cover of the vibrating screen.

[0011] Furthermore, the vertical distance between the disc and the first layer of the vibrating screen is 8-12 cm.

[0012] Furthermore, the number of diversion holes is 3-6, the diameter of the holes is 10-30mm, and they are centrally symmetrically distributed.

[0013] Furthermore, the suspension assembly includes at least three stainless steel hooks, each with an anti-detachment buckle at its end.

[0014] Furthermore, the stainless steel hook is welded around the disc and installed on the feed inlet of the vibrating screen using anti-detachment buckles.

[0015] Furthermore, the disc is made of 304 or 316 stainless steel.

[0016] Furthermore, the edge of the disc is provided with an upwardly extending baffle ring with a ring height of 10-20mm.

[0017] Furthermore, the diameter of the disk is 200mm.

[0018] To achieve the above objectives, this utility model also provides a vibrating screen, including a material buffer device on the dust cover of the vibrating screen as described above.

[0019] Beneficial effects: This utility model buffers the material by installing a disc with diversion holes at the feed inlet of the vibrating screen, thereby reducing the impact of the material on the screen and effectively improving the service life of the screen. Attached Figure Description

[0020] The accompanying drawings, which form part of this utility model, are used to provide a further understanding of the utility model. The illustrative embodiments of the utility model and their descriptions are used to explain the utility model and do not constitute an undue limitation of the utility model. In the drawings:

[0021] Figure 1 This is a schematic diagram of the material buffer device on the dust cover of the vibrating screen according to an embodiment of the present invention;

[0022] Figure 2 This is a schematic diagram of the disc of the material buffer device on the dust cover of the vibrating screen according to an embodiment of the present invention. Detailed Implementation

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] See Figure 1-2 A material buffer device on a dust cover of a vibrating screen, comprising:

[0027] The diameter of the disc 1 matches the diameter of the feed inlet 201 of the vibrating screen 2;

[0028] A plurality of flow dividers 101 are formed on the disk 1;

[0029] The detachable suspension assembly 3 is used to fix the disc 1 under the dust cover 202 of the vibrating screen 2.

[0030] It should be noted that when the screen is being fed, the disc and the diversion holes will disperse the material flow, reduce the impact of the material on the screen, and effectively improve the service life of the screen.

[0031] In a specific example, the vertical distance between the disc 1 and the first layer of screen 203 of the vibrating screen 2 is 8-12 cm.

[0032] The 8-12cm vertical spacing in this embodiment buffers material impact and avoids wasting space.

[0033] In a specific example, the number of diversion holes 101 is 3-6, the diameter of the holes is 10-30mm, and they are centrally symmetrically distributed.

[0034] The 3-6 centrally symmetrical diversion holes (10-30mm) in this embodiment can adjust the material falling speed and distribution range.

[0035] In one specific example, the suspension assembly 3 includes at least three stainless steel hooks, each with an anti-detachment buckle at its end.

[0036] In one specific example, the stainless steel hook is welded around the disc and installed on the feed inlet 201 of the vibrating screen 2 by means of an anti-detachment buckle.

[0037] Stainless steel hooks are welded to the perimeter of the disc (with anti-detachment buckles) for easy maintenance and to ensure structural stability.

[0038] In one specific example, the disk 1 is made of 304 or 316 stainless steel.

[0039] 304 / 316 stainless steel is corrosion resistant and suitable for use in industries such as chemical engineering.

[0040] In a specific example, the edge of the disk 1 is provided with an upwardly extending baffle ring 102, with a ring height of 10-20mm.

[0041] The baffle ring (10-20mm) and the dust cover form a closed structure, effectively suppressing the spread of materials and dust.

[0042] In a specific example, the disk 1 has a diameter of 200 mm.

[0043] In summary, this embodiment utilizes a stainless steel porous disc to disperse the impact force of materials entering the vibrating screen during screening. The material at the screen inlet is diverted and buffered by the stainless steel porous disc, preventing the material from directly impacting the screen mesh. This reduces the wear on the screen mesh tension, significantly extends the screen mesh's service life, and effectively lowers screening production costs.

[0044] Example 2

[0045] To achieve the above objectives, this embodiment also provides a vibrating screen, including a material buffer device on the dust cover of the vibrating screen as described above.

[0046] The vibrating screen in this embodiment has the same advantages over the prior art as the material buffer device on the dust cover of the vibrating screen described above, and will not be repeated here.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
