Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, specifically a ceramic ball screening device. Background Technology

[0002] In existing technologies, ceramic balls often become mixed with balls of different diameters after molding. The difference between the balls is small, so a screen is needed to screen them to meet the requirements. Since different diameters correspond to different needs, each size range needs to be separated separately. Therefore, multiple screenings are required. The specific equipment operation method is as follows: screening is carried out by vibrating equipment in conjunction with a screen, and multiple screens with different mesh sizes are used to complete the separation operation in batches. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a ceramic ball screening device that features high screening efficiency.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A ceramic ball screening device, comprising:

[0006] A sieve cylinder includes several tubular screens arranged coaxially from the inside out, forming several screening chambers. One end of each screening chamber has an inlet, and the other end has an outlet. The diameter of the tubular screens gradually increases from the inside out, while the aperture of the screens gradually decreases.

[0007] A plurality of plugs are provided, wherein the plugs are detachably mounted on the screen cylinder, and the plurality of plugs correspond one-to-one with the outlets of the plurality of screening chambers and are capable of sealing the outlets;

[0008] A drive assembly is connected to the screen cylinder and is used to drive the screen cylinder to rotate.

[0009] The ceramic ball screening device described above also includes a cylindrical body, which is fixed to the outermost side of the screen cylinder and forms a cavity with the screen cylinder.

[0010] In the above-mentioned ceramic ball screening device, the tubular screen inside the screen cylinder is fixedly connected by several supports.

[0011] In the above-mentioned ceramic ball screening device, the support is fixedly connected to the cylinder.

[0012] In the above-mentioned ceramic ball screening device, the plug has a protrusion that can be inserted into the outlet of the screening chamber.

[0013] In the above-mentioned ceramic ball screening device, the tubular screen is provided with an internal thread at the end near the outlet, and the protrusion of the plug is provided with an external thread, and the protrusion is threadedly connected to the tubular screen.

[0015] The ceramic ball screening device described above also includes a guide tube, which is detachably connected to the inlet of the tubular screen with the smallest aperture.

[0016] Compared with the prior art, this application has the following advantages:

[0017] With multiple tubular screens coaxially arranged, ceramic balls of various sizes can be screened simultaneously in one rotation, which changes the cumbersome operation of traditional equipment that requires multiple screen replacements and significantly shortens the screening time.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1 to 4 As shown, a ceramic ball screening device includes: a screen cylinder 2, several plugs 3, and a drive assembly 4. The screen cylinder 2 includes several coaxially arranged tubular screens 21 arranged from the inside to the outside to form several screening chambers 22. One end of the screening chamber 22 has an inlet 221, and the other end has an outlet 222. The diameter of the several tubular screens 21 gradually increases from the inside to the outside, and the aperture of the tubular screens 21 gradually decreases. The plugs 3 are detachably mounted on the screen cylinder 2. The several plugs 3 correspond one-to-one with the outlets 222 of the several screening chambers 22, and can close the outlets 222. The drive assembly 4 is connected to the screen cylinder 2 and is used to drive the screen cylinder 2 to rotate.

[0029] When the ceramic balls enter the innermost screening chamber 22 from the inlet 221 of the screen cylinder 2, the drive component 4 drives the screen cylinder 2 to rotate. Under the action of centrifugal force and gravity, the ceramic balls come into contact with the inner tubular screen 21. Since the inner screen has the smallest aperture, ceramic balls smaller than this aperture will fall into the adjacent outer screening chamber 22 through the screen, while balls larger than the aperture will remain in the original chamber. As the screen cylinder 2 continues to rotate, the ceramic balls in each screening chamber 22 continuously come into contact with the corresponding screen and pass through the screen aperture that matches their own diameter in turn. Finally, ceramic balls of different diameters gather in each screening chamber 22. At this time, the corresponding plug 3 can be removed as needed, and the outlet 222 can be opened to allow ceramic balls of a specific diameter range to be discharged from the corresponding outlet 222, thus completing the screening operation.

[0030] With the multi-layer tubular screen 21 coaxially arranged, multiple sizes of ceramic balls can be screened simultaneously in one rotation, which changes the cumbersome operation of traditional equipment that requires multiple screen replacements and significantly shortens the screening time. The blocker 3 can selectively open or close the outlet 222 according to the actual screening needs, and can achieve the screening of balls of a specific diameter range.

[0031] In use, the sieve cylinder 2 needs to be tilted so that the raw material inside can contact the holes on the tubular sieve 21 as much as possible, thereby improving the screening efficiency.

[0032] Specifically, it also includes a cylinder 23, which is fixed to the outermost side of the screen cylinder 2 and forms a cavity 231 with the screen cylinder 2.

[0033] The cavity 231 formed by the cylinder 23 and the outermost layer of the screen cylinder 2 can serve as a collection space for the final screened material, preventing the ceramic balls screened by the outermost screen from falling directly, and also providing protection during the rotation of the screen cylinder 2.

[0034] Specifically, the tubular screen 21 inside the screen cylinder 2 is fixedly connected by several supports.

[0035] The support frame coaxially fixes the multi-layer tubular screen 21, strictly maintaining the relative position and aperture gradient of each layer of screen.

[0036] Specifically, the bracket is fixedly connected to the cylinder 23.

[0037] Specifically, the plugger 3 has a protrusion 31 that can be inserted into the outlet 222 of the screening chamber 22.

[0038] After the protrusion 31 is inserted into the outlet 222, the ceramic balls in the corresponding screening chamber 22 can be temporarily retained to prevent the balls that have not been screened from being discharged in advance, and to ensure that the materials in each diameter range can pass through the corresponding screen during the rotation of the screen cylinder 2.

[0039] Specifically, the tubular screen 21 has an internal thread at the end near the outlet 222, and the protrusion 31 of the plugger 3 has an external thread, which is threaded onto the tubular screen 21.

[0040] The meshing of the internal and external threads forms a spiral locking structure, which, compared to the traditional plug-in type plug, can withstand the centrifugal force and material impact when the screen cylinder 2 rotates, and avoid leakage at the outlet 222 caused by the loosening of the protrusion 31. The thread direction can be customized according to the rotation direction of the screen cylinder 2, and the thread direction is opposite to the rotation direction.

[0041] Specifically, the drive assembly 4 includes a drive motor, the drive connection is located on the inlet 221 side of the screening chamber 22, and is fixedly connected to the bracket.

[0042] The output shaft of the drive motor is directly or via a coupling connected to the central shaft of the screen cylinder 2, converting the rotational power of the motor into the coaxial rotation of the screen cylinder 2.

[0043] Specifically, it also includes a conduit 5, which is detachably connected to the inlet 221 of the tubular screen 21 with the smallest aperture.

[0044] The guide tube 5 is directly connected to the inner screen inlet 221 with the smallest aperture, ensuring that the raw materials enter the innermost screening chamber 22 as soon as possible, avoiding material accumulation outside the screen cylinder 2 or misaligned entry. After the raw materials are fed in, the guide tube 5 is disassembled.

[0045] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture, as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.
