Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of screening technology, and more specifically, to a vibrating screen device for ball-milled aluminum ore slurry. Background Technology

[0002] After being crushed and ground, bauxite becomes aluminum ore slurry. Currently, the crushing and grinding of bauxite is usually carried out using ball mills. However, the grinding effect of ball mills is not ideal. After grinding, some particles will still not meet the requirements in terms of particle size. In order to ensure that the particle size of the finished product meets the requirements, it is necessary to perform screening.

[0003] In the existing technology, due to the different particle sizes and irregular shapes, the screen holes of the vibrating screen are usually blocked by some material during screening. When the blockage increases, the screening efficiency of the vibrating screen will decrease. The cleaning process of the existing technology usually requires stopping the machine for cleaning, and cleaning the vibrating screen also takes time, which will also affect the production efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a vibrating screen device for aluminum ore slurry after ball milling, which solves the problem in the prior art that irregular bauxite particles cause screen plate blockage during aluminum ore slurry screening, requiring a lot of time to clean and resulting in reduced production efficiency.

[0005] According to one aspect, at least one embodiment of this disclosure provides a vibrating screen device for ball-milled aluminum ore slurry, used for screening the ground aluminum ore slurry, including:

[0006] Screen frame;

[0007] The vibrator is mounted on the screen frame;

[0008] A sieve plate is disposed at the bottom of the sieve frame. The sieve plate has a plurality of sieve holes and is used to screen aluminum ore slurry.

[0009] A cleaning plate is slidably disposed on the screen frame. Several cleaning plates are located below the screen plate and abut against the screen plate. The cleaning plate has several slots. After the cleaning plate slides, the screen holes and the slots are connected or disconnected.

[0010] For example, in a vibrating screen device for ball-milled aluminum ore slurry provided in at least one embodiment of this disclosure, the screen frame has a feed end and a discharge end, and the screen frame is inclined.

[0011] For example, in at least one embodiment of this disclosure, a vibrating screen device for ball-milled aluminum ore slurry further includes:

[0012] The first leg, having several components, is located at the feed end;

[0013] The second leg, which has several parts, is located at the discharge end;

[0014] Several mounting bases are provided on the screen frame, and the first support leg and the second support leg are provided on the screen frame via the mounting bases.

[0015] For example, in at least one embodiment of this disclosure, a vibrating screen device for ball-milled aluminum ore slurry further includes:

[0016] The elastic element has several parts, with its two ends respectively disposed on the mounting base and the first leg and the second leg. The elastic element is used to enhance the vibration effect of the vibrator.

[0017] For example, in at least one embodiment of this disclosure, a vibrating screen device for ball-milled aluminum ore slurry further includes:

[0018] The first guide chute is disposed on the screen frame and located below the screen plate. The first guide chute is used to guide the small aluminum ore particles that have been screened to leave.

[0019] The second guide chute is located at the discharge end of the screen frame and is used to guide large particles of aluminum ore.

[0020] For example, in at least one embodiment of this disclosure, a vibrating screen device for ball-milled aluminum ore slurry further includes:

[0021] A linear drive is mounted on the screen frame. The telescopic end of the linear drive is connected to the cleaning plate, and the linear drive is used to drive the cleaning plate to slide.

[0022] For example, in a ball-milled aluminum ore slurry vibrating screen device provided in at least one embodiment of this disclosure, the first guide chute and the second guide chute are also arranged at an incline.

[0023] For example, in a ball milling aluminum ore slurry vibrating screen device provided in at least one embodiment of this disclosure, the first guide trough has a V-shaped cross section, which is used to gather small particles of material after screening.

[0024] For example, in at least one embodiment of this disclosure, a vibrating screen device for ball-milled aluminum ore slurry further includes:

[0025] A dustproof housing is provided on the screen frame, and the linear drive component is located inside the dustproof housing.

[0026] For example, in a vibrating screen device for ball-milled aluminum ore slurry provided in at least one embodiment of this disclosure, the cleaning plate has several pieces and further includes:

[0027] A connecting rod is slidably mounted on the screen frame, and several cleaning plates are sequentially mounted on the connecting rod.

[0028] The beneficial effects of the embodiments disclosed herein are as follows:

[0029] In this disclosure, since the aluminum ore slurry is produced by grinding in a ball mill, the ground material particles are not uniform. Therefore, a small portion of particles will clog the screen holes during the screening process, resulting in a decrease in the screening capacity of the screen plate. The cleaning plate is located below the screen plate and directly abuts against it. The slots on the cleaning plate are larger than the screen holes. The cleaning plate can also clean the screen while it is operating. Whenever the screen holes are clogged and need cleaning, the cleaning plate frequently slides to close and open the screen holes, which can shear or rotate the irregular particles that were originally blocking the screen holes, thus cleaning the screen holes. During cleaning, the vibrator on the screen frame is turned on. When the screen holes are closed, the large particles above will gradually leave the screen frame with the vibration, ensuring that the screen holes will not clog again.

[0030] The advantage of this design is that the cleaning plate is slidably mounted on the screen frame and abuts against the screen plate. When the screen holes are blocked by material, the sliding cleaning plate connects the screen holes with the slots, clearing the blocked material and preventing continuous blockage from affecting screening efficiency. The sliding cleaning plate can clean the screen holes promptly without affecting normal screening operations, ensuring the continuous and efficient operation of the screening device, reducing downtime required for screen blockage and cleaning, and improving production efficiency.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] like Figures 1-4 The diagram illustrates a vibrating screen device for ball-milled aluminum ore slurry according to an embodiment of this disclosure, comprising a screen frame 110; a vibrator 120 disposed on the screen frame 110; a screen plate 130 disposed at the bottom of the screen frame 110, the screen plate 130 having a plurality of screen holes 131, the screen plate 130 being used for screening the aluminum ore slurry; and a cleaning plate 140 slidably disposed on the screen frame 110, a plurality of cleaning plates 140 being located below the screen plate 130 and abutting against the screen plate 130, the cleaning plate 140 having a plurality of slots 141, the screen holes 131 being connected to or disconnected from the slots 141 after the cleaning plate 140 is slidable.

[0044] In practical applications, the alumina ore slurry after grinding has a very small particle size but an irregular shape. During screening, larger particles can clog the screen holes 131, preventing material from passing through. Therefore, after screening a batch of alumina ore slurry, the vibrating screen needs to be cleaned. Conventional cleaning is time-consuming and affects production efficiency. In this solution, the screen plate 130 is cleaned by a cleaning plate 140 located below. When screen holes 131 become clogged after screening a batch of material, due to the small particle size of the alumina ore slurry, the sliding of the cleaning plate 140 will disconnect the slots 141 that were originally connected to the screen holes 131. The slots 141 will cut off or push out the material that was originally blocking the screen holes 131. At this time, the vibrator 120 drives the screen frame 110 to vibrate, and the originally blocked alumina ore particles will leave the screen plate 130 with the vibration, thus cleaning the screen plate 130. The screen frame 110 provides a stable mounting base for the vibrator 120 and the screen plate 130, ensuring the structural stability of the entire screening device. During normal screening, after the aluminum ore slurry enters the screen frame 110, the vibrator 120 vibrates the screen body, causing the aluminum ore slurry to vibrate. Small particles of slurry fall through the screen holes 131, while larger particles remain above the screen plate 130. After screening, the larger particles are re-ground. However, since the aluminum ore slurry is ground using a ball mill, the particles are not uniform. Therefore, a small number of particles may block the screen holes 131 during screening, resulting in a decrease in the screening capacity of the screen plate 130. The cleaning plate 140 is located below the screen plate 130 and directly abuts against it. The slots 141 on the cleaning plate 140 are larger than the screen holes 131. The cleaning plate 140 can also clean the screen while it is operating. Whenever the screen hole 131 is blocked and needs cleaning, the cleaning plate 140 frequently slides to close and open the screen hole 131, which can shear or rotate the irregular particles that were originally blocking the screen hole 131, thus cleaning the screen hole 131. During cleaning, the vibrator 120 on the screen frame 110 is turned on. After the screen hole 131 is closed, the large particles above will gradually leave the screen frame 110 with the vibration, ensuring that the screen hole 131 is no longer blocked.

[0045] The advantage of this design is that the cleaning plate 140 is slidably mounted on the screen frame 110 and abuts against the screen plate 130. When the screen holes 131 are blocked by material, the sliding cleaning plate 140 connects the screen holes 131 with the slot holes 141, clearing the blocked material and preventing the screen holes 131 from becoming continuously blocked and affecting screening efficiency. The sliding cleaning plate 140 can clean the screen holes 131 in a timely manner without affecting normal screening operations, ensuring the continuous and efficient operation of the screening device, reducing downtime required for screen hole 131 blockage and cleaning, and improving production efficiency.

[0046] In some examples, the screen frame 110 has a feed end 111 and a discharge end 112, and the screen frame 110 is inclined; it also includes: a plurality of first legs 210 located at the feed end 111; a plurality of second legs 220 located at the discharge end 112; a plurality of mounting seats 230 disposed on the screen frame 110; and a plurality of elastic members 240, with both ends respectively disposed on the mounting seat 230 and the first leg 210 or the second leg 220.

[0047] In practical applications, the feed end 111 is higher than the discharge end 112. Therefore, the height of the first leg 210 is slightly higher than that of the second leg 220. After the material enters the screen frame 110 from the feed end 111, it is gradually screened by the screen plate 130 under the vibration of the vibrator 120 and leaves from the discharge end 112. The inclined screen frame 110 can ensure that the material will gradually move towards the discharge end 112 under the action of gravity when vibrating. The elastic element 240 is a spring. The mounting seat 230 on the screen frame 110 is connected to the first leg 210 and the second leg 220 through the elastic element 240. When the vibrator 120 is turned on, it can improve the vibration effect.

[0048] The advantage of this design is that the first support legs 210 located at the feed end 111 and the second support legs 220 located at the discharge end 112 provide stable support for the inclined screen frame 110, ensuring that the screen frame 110 will not shake or tilt during operation, thus guaranteeing the stability and safety of the equipment. The mounting base 230 provides a fixed mounting position for the elastic element 240, making the installation of the elastic element 240 more secure and reliable. The elastic element 240 connects the mounting base 230 and the support legs, playing a buffering and shock-absorbing role, reducing the impact of screen frame 110 vibration on the support legs and the entire equipment, and extending the service life of the equipment.

[0049] In some examples, a first guide chute 310 is disposed on the screen frame 110 and located below the screen plate 130, and the first guide chute 310 is used to guide small aluminum ore particles that have been screened to leave; a second guide chute 320 is disposed at the discharge end 112 of the screen frame 110, and the second guide chute 320 is used to guide large aluminum ore particles.

[0050] In practical applications, the first guide chute 310 effectively guides the orderly exit of small aluminum ore particles after screening, preventing accumulation of small particles below the screen plate 130 and ensuring the continuity and smoothness of the screening process. The second guide chute 320, located at the discharge end 112 of the screen frame 110, is specifically designed to guide large aluminum ore particles, enabling accurate collection and processing, thus improving material classification and processing efficiency. The design of these two guide chutes allows the screened material to be quickly and accurately guided to its designated location, facilitating subsequent processing or transportation and reducing material disorder and cross-contamination. The first and second guide chute 310 also help maintain a clean work site, reducing material spillage and waste, and lowering cleaning and maintenance costs.

[0051] In some examples, the linear drive 410 is mounted on the screen frame 110, and the telescopic end 411 of the linear drive 410 is connected to the cleaning plate 140. The linear drive 410 is used to drive the cleaning plate 140 to slide.

[0052] In practical applications, the linear drive 410 provides stable and controllable power for the sliding of the cleaning plate 140, ensuring that the cleaning plate 140 can slide accurately and timely to the required position for cleaning or resetting the screen holes 131. Automated telescopic control reduces the labor intensity and uncertainty of manual operation and improves the accuracy and efficiency of the sliding of the cleaning plate 140.

[0053] In some examples, the first feed chute 310 and the second feed chute 320 are also arranged at an incline. The first feed chute 310 has a V-shaped cross-section, which is used to gather small particles of material after screening.

[0054] In practical applications, the inclined arrangement of the first feed chute 310 helps small particles flow more smoothly under gravity, improving material transport efficiency. The V-shaped cross-section of the first feed chute 310 effectively gathers small particles, reducing material dispersion and leakage, ensuring that more material is accurately guided and transported. The first feed chute 310 and the second feed chute 320 correspond to two transfer devices, which transfer the screened material. Small particles can be directly used in the next process, while large particles are transported to the ball mill for further grinding by the corresponding transfer device.

[0055] In some examples, the dust cover 710 is mounted on the screen frame 110, and the linear drive 410 is located inside the dust cover 710.

[0056] In practical applications, the dust cover 710 effectively protects the linear drive component 410 from the intrusion of external dust and impurities, reducing problems such as jamming and wear caused by dust accumulation, and extending the service life of the linear drive component 410. It prevents dust from entering the interior of the linear drive component 410 and affecting the accuracy and stability of its normal telescopic movement, ensuring the accuracy and reliability of the sliding of the cleaning plate 140. The dust cover 710 provides a relatively enclosed working environment for the linear drive component 410, reducing the impact of external environmental factors on its performance and enabling the linear drive component 410 to operate under more stable conditions.

[0057] In some examples, the cleaning plate 140 has several blocks and also includes: a connecting rod 810 slidably disposed on the screen frame 110, and several cleaning plates 140 are sequentially disposed on the connecting rod 810.

[0058] In practical applications, the arrangement of several cleaning plates 140 allows for simultaneous cleaning of a larger area of ​​the screen plate 130, improving cleaning efficiency. Connecting rods 810 sequentially connect the cleaning plates 140, enabling them to slide synchronously and ensuring consistency and coordination of the cleaning actions. The sliding connecting rods 810 facilitate overall adjustment and control of the cleaning plate 140's position, making operation more convenient. This structural design reduces the complex mechanisms required to individually control each cleaning plate 140, lowering costs and reducing the failure rate.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
