Description

Technical Field

[0001] The present invention relates to the technical field of kaolin filtration, and specifically to a rapid filter for kaolin processing. Background Art

[0002] Kaolin raw ore often contains sandy minerals such as quartz, feldspar, and mica, as well as coloring impurities such as iron, titanium, and carbon. These impurities will reduce the whiteness, purity, and application performance of the product. Downstream industries (such as ceramics and papermaking) have strict requirements for the whiteness, fineness, and chemical stability of kaolin. Filtration is the key step to achieve these indicators. When the existing rapid filter for kaolin processing is in use, it will filter impurities through a filter plate. First, the slurry composed of kaolin and water is discharged, and then the impurities are discharged after the filtration process ends. However, there are still the following technical problems, such as: The filtration efficiency of the existing rapid filter for kaolin processing is not good. The reason is that most of the filter meshes on it are fixedly installed, which leads to insufficient efficiency when the existing filter filters kaolin. For example, a kaolin filtration device disclosed in the publication number CN219765967U is connected by a fixed motor, a fixed shaft, and a fixed plate, so that when discharging materials, the filter plate can be rotated, which can only achieve the purpose of facilitating material discharge and cannot improve the filtration efficiency and effect of the filter plate. In addition, when it is necessary to discharge impurities, the above-mentioned existing technology rotates the filter plate through a fixed motor, resulting in an increase in the energy consumption required for the entire device, which is not conducive to energy conservation and emission reduction. Therefore, a rapid filter for kaolin processing is needed to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to provide a rapid filter for kaolin processing to solve the problems of poor filtration efficiency and effect, high energy consumption, and being not conducive to energy conservation and emission reduction in the existing rapid filter for kaolin processing mentioned in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: A rapid filter for kaolin processing, comprising a support base and support arms mounted thereon at equal angles. The upper end of the support arm is fixedly connected to a filter cavity coaxial with the support base. The inner bottom surface of the filter cavity is provided with a mounting seat, and a servo motor is installed inside the mounting seat. The shaft end of the servo motor penetrates above the mounting seat. An installation frame is arranged inside the filter cavity, and the lower surface of the installation frame is connected to the shaft end of the servo motor through a bump transmission mechanism. The inside of the installation frame is connected to the upper surface of the mounting seat through a support mechanism, and a shield is installed at the top of the installation frame, leaving gaps at the upper two corners of the installation frame. Shaft columns penetrate through the gaps of the two installation frames, and the shaft columns are pivotally connected to the installation frames so that the shaft columns can rotate relative to the installation frames. The top end of each shaft column is connected to a filter plate, and the two shaft columns are supported by a support mechanism. The center of gravity of the filter plate is close to its outer edge.

[0005] Preferably, the inner bottom surface of the filter cavity is an inverted hollow frustum shape, and two discharge ports penetrating through both sides thereof are symmetrically arranged on the inner bottom surface of the filter cavity. Two connecting pipes are symmetrically installed on the lower surface of the installation frame, and the lower end of each connecting pipe is nested with the upper end of a corresponding connecting rod. The lower end of each connecting rod is connected to a corresponding scraper, and the lower surface of the scraper is in contact with and slidably connected to the inner bottom surface of the filter cavity.

[0006] Preferably, the bump transmission mechanism includes a transmission disk key-connected coaxially to the shaft end of the servo motor, and the upper end of the transmission disk extends into the lower end of the connecting disk movably. The upper end of the connecting disk is fixedly connected to the lower surface of the installation frame coaxially. The transmission disk is connected to the inner side of the bump ring assembly by bearings, and the bump ring assembly is fixedly connected to the upper surface of the mounting seat. Right-angled triangular prism blocks are arranged at equal angles on the upper surface of the bump ring assembly and the lower surface of the connecting disk, and the right-angled triangular prism blocks between them are arranged in one-to-one correspondence, and the inclined surfaces of the corresponding right-angled triangular prism blocks are arranged opposite to each other.

[0007] Preferably, a prism-shaped protrusion coaxial with it is arranged on the upper surface of the transmission disk, and a prism-shaped groove is arranged on the lower surface of the connecting disk. The prism-shaped protrusion and the prism-shaped groove are slidably engaged.

[0008] Preferably, the support mechanism includes a support rod arranged between the two shaft columns, and pressure wheels are arranged at both ends of the support rod. The two pressure wheels are respectively in rolling connection with the two shaft columns. Two sleeve blocks are movably nested on the support rod, and a tension-bearing spring nested outside the support rod is arranged between the two sleeve blocks. The inner bottom surface of the installation frame is connected to the two sliding frames through two slider-chute assemblies respectively, and the two sliding frames are symmetrically arranged about the axis center of the installation frame. The lower surface of each sleeve block is pivotally connected to the upper end of a corresponding support arm, and the lower end of the support arm is pivotally connected to the end of the corresponding sliding frame.

[0009] Preferably, limiting holes are provided on both of the sliding frames, and one end of a corresponding limiting shaft movably extends into each limiting hole, and the other end of the limiting shaft is fixedly connected to the side surface of the opposite sliding frame.

[0010] Preferably, the propping mechanism further includes a support gear fixedly connected to the upper surface of the mounting seat, and the support gear is coaxially arranged with the bump ring assembly. Two shaft rods penetrate through the lower surface of the mounting frame by bearings, and a driven gear and a follower gear are respectively key-connected to the upper and lower ends of each shaft rod. The follower gear is meshed and connected to the outside of the support gear. Fixed teeth are evenly distributed on the inner side of the sliding frame, and the fixed teeth are meshed and connected to the corresponding driven gear.

[0011] Preferably, T-shaped rods are provided on one side of the two sliding frames opposite to each other, and movable teeth are movably nested on the T-shaped rods. A return spring is provided between one side of the movable teeth and one side of the corresponding sliding frame and between the other side of the movable teeth and the end of the T-shaped rod, and the return spring is movably nested on the outside of the middle part of the T-shaped rod.

[0013] Preferably, the thickness of the follower gear is not greater than 1 / 2 of the thickness of the support gear, and the thickness of the follower gear is greater than the length of the right-angled short side of the triangular prism block, ensuring that the follower gear will not be separated from the support gear during the up-and-down reciprocating bumping process of the mounting frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The rapid filter for kaolin processing can improve the filtering efficiency and effect through the rotation and vibration of the filter plate, and when impurities need to be discharged, the filter plate can automatically rotate due to its own weight, avoiding additional energy-consuming components such as motors, thus contributing to energy conservation and emission reduction. In addition, during discharging, the discharging effect can be improved by the scraper: 1. When the servo motor drives the driving disk to rotate, the mounting frame can be driven to rotate through the connecting disk, and then the filter plate mounted on the mounting frame can be rotated. In addition, through the right-angled triangular prism blocks arranged on the upper surface of the bump ring assembly and the lower surface of the connecting disk, the mounting frame can move up and down during the rotation process, and then the filter plate mounted thereon vibrates, which is beneficial to improving the filtering efficiency and effect of the filter plate; 2. When the servo motor is running, it drives the installation frame to rotate, causing the follower gear to rotate around the support gear. At this time, the driven gear is driven to rotate through the shaft rod, prompting the sliding frame to move, making the two sleeve blocks move away from each other, causing the tension spring between them to generate elastic potential energy, and causing the support rod to move downward. Then, the two pressure wheels press against the two shaft columns. At this time, the two shaft columns will be in a parallel state, so that the two filter plates can be spliced, and then the two filter plates can be used for filtering operations. When the servo motor stops running, under the action of the tension spring resetting, the support rod will move upward. At this time, under the action of their own gravity, the two filter plates will rotate away from each other, and then the impurities on the filter plates can be automatically discharged, avoiding the additional installation of other energy-consuming components such as motors; 3. Through the connecting rod and the connecting pipe, the scraper can rotate together with the installation frame. Then, during the discharging process, the scraper can discharge the impurities or the filtered kaolin slurry from the filtering cavity more thoroughly. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-11 , the present invention provides the following technical solutions: Embodiment 1: To solve the problem that the conventional rapid filter for kaolin processing cannot improve the filtration efficiency and effect during use, the following technical solutions are provided. Specifically, a rapid filter for kaolin processing includes a support base 1 and support arms 2 equally angularly installed thereon. The upper end of the support arm 2 is fixedly connected to a filtration cavity 3 coaxial with the support base 1. The inner bottom surface of the filtration cavity 3 is provided with a mounting seat 15, and a servo motor 16 is installed inside the mounting seat 15. The shaft end of the servo motor 16 penetrates above the mounting seat 15. A mounting frame 4 is arranged inside the filtration cavity 3, and the lower surface of the mounting frame 4 is connected to the shaft end of the servo motor 16 through a bump transmission mechanism.

[0019] The bump transmission mechanism includes a transmission disk 19 coaxially and key-connected to the shaft end of the servo motor 16. The upper end of the transmission disk 19 extends into the lower end of the connection disk 31 movably. The upper end of the connection disk 31 is coaxially and fixedly connected to the lower surface of the mounting frame 4. The transmission disk 19 is connected to the inner side of the bump ring assembly 20 by bearings, and the bump ring assembly 20 is fixedly connected to the upper surface of the mounting seat 15. Right-angled triangular prism blocks are arranged at equal angles on the upper surface of the bump ring assembly 20 and the lower surface of the connection disk 31, and the right-angled triangular prism blocks between the two are arranged in one-to-one correspondence. The inclined surfaces of the corresponding right-angled triangular prism blocks are arranged opposite to each other. A prism-shaped protrusion coaxial with it is arranged on the upper surface of the transmission disk 19, and a prism-shaped groove is arranged on the lower surface of the connection disk 31. The prism-shaped protrusion and the prism-shaped groove are slidably engaged. During use, due to the operation of the servo motor 16, the transmission disk 19 rotates. Through the slidable engagement between the prism-shaped protrusion and the prism-shaped groove, the transmission disk 19 can drive the connection disk 31 to rotate synchronously, and it does not affect the relative movement of the transmission disk 19 driving the connection disk 31. During the rotation of the two, through the mutually corresponding right-angled triangular prism blocks, the connection disk 31 can be made to reciprocate up and down relative to the transmission disk 19, so that the mounting frame 4 vibrates up and down during rotation. Since the mounting frame 4 is connected to the filter plate 5 through the shaft column 8, during the operation of the servo motor 16, the filter plate 5 will rotate and vibrate up and down, which helps to improve the filtering efficiency and effect.

[0020] Embodiment 2: To solve the problem that when the quick filter for kaolin processing in the past needed to discharge impurities, an additional motor and other energy-consuming components were required to rotate the filter plate, resulting in an increase in energy consumption. The following technical solution is provided. Specifically, the inside of the mounting frame 4 is connected to the upper surface of the mounting seat 15 through a support mechanism. A shield 7 is installed at the top of the mounting frame 4, leaving gaps exposed at the two upper corners of the mounting frame 4. Shaft columns 8 penetrate through the gaps in the two mounting frames 4, and the shaft columns 8 are pivotally connected to the mounting frame 4 so that the shaft columns 8 can rotate relative to the mounting frame 4. The top of each shaft column 8 is connected to a filter plate 5, and the two shaft columns 8 are supported by a support mechanism. The center of gravity of the filter plate 5 is close to its outer edge.

[0021] The supporting mechanism includes a supporting rod 10 arranged between two shaft columns 8. Pressing wheels 9 are arranged at both ends of the supporting rod 10. The two pressing wheels 9 are respectively in rolling connection with the two shaft columns 8. Two sleeve blocks 11 are movably nested on the supporting rod 10. A tension-bearing spring 12 nested outside the supporting rod 10 is arranged between the two sleeve blocks 11. The inner bottom surface of the installation frame 4 is respectively connected with the two sliding frames 23 through two slider-chute assemblies 24. The two sliding frames 23 are symmetrically arranged about the axis center of the installation frame 4. The lower surface of each sleeve block 11 is axially connected to the upper end of the corresponding supporting arm 13. The lower end of the supporting arm 13 is axially connected to the end of the corresponding sliding frame 23. Limit holes are arranged on the two sliding frames 23. One end of the corresponding limit shaft 25 movably extends into each limit hole. The other end of the limit shaft 25 is fixedly connected to the side surface of the opposite sliding frame 23. The supporting mechanism further includes a supporting gear 21 fixedly connected to the upper surface of the mounting seat 15. The supporting gear 21 is coaxially arranged with the bump ring assembly 20. Two shaft rods 14 penetrate through the lower surface of the installation frame 4 by bearings. A driven gear 26 and a follower gear 22 are respectively key-connected to the upper and lower ends of each shaft rod 14. The follower gear 22 is meshed and connected to the outside of the supporting gear 21. Fixed teeth 27 are evenly distributed on the inner side of the sliding frame 23. The fixed teeth 27 are meshed and connected to the corresponding driven gear 26. T-shaped rods 28 are arranged on one side of the two sliding frames 23 facing each other. Movable teeth 29 are movably nested on the T-shaped rods 28. A return spring 30 is arranged between one side of the movable teeth 29 and one side of the corresponding sliding frame 23 and between the other side of the movable teeth 29 and the end of the T-shaped rod 28. The return spring 30 is movably nested on the outside of the middle part of the T-shaped rod 28. During use, since the installation frame 4 rotates, the follower gear 22 rotates on the outside of the supporting gear 21, so that the driven gear 26 drives the sliding frame 23 to move through the fixed teeth 27. During this process, the two sleeve blocks 11 move away from each other, so that the tension-bearing spring 12 is pulled and elastic potential energy is generated. In addition, the supporting rod 10 drives the pressing wheels 9 to move downward synchronously, so as to press the two shaft columns 8, so that the two shaft columns 8 reach a parallel state. Thus, the two filter plates 5 are spliced. When the servo motor 16 stops running, since the gravity of the filter plate 5 is close to its outer edge, the two filter plates 5 will rotate in opposite directions by their own gravity. During this process, the installation frame 4 will rotate reversely and vibrate, which is beneficial to the discharge of impurities on the filter plate 5. Since no additional energy-consuming components such as motors need to be added during the process of the two filter plates 5 rotating in opposite directions, it is beneficial to reduce energy consumption and contribute to energy conservation and emission reduction.

[0022] The tooth number ratio of the supporting gear 21 to the follower gear 22 is not less than 5. When the supporting gear 21 rotates relatively slowly, the follower gear 22 rotates at a high speed. The thickness of the follower gear 22 is not greater than 1 / 2 of the thickness of the supporting gear 21, and the thickness of the follower gear 22 is greater than the length of the right-angled short side of the triangular prism block, ensuring that the follower gear 22 will not be disengaged from the supporting gear 21 during the up-and-down reciprocating bumping of the mounting frame 4.

[0023] Embodiment 3: To solve the problem that the conventional rapid filter for kaolin processing cannot discharge the internal impurities or kaolin slurry more thoroughly, the following technical solution is provided. Specifically, the inner bottom surface of the filter cavity 3 is an inverted hollow frustum shape, and two discharge ports 32 penetrating both sides thereof are symmetrically arranged on the inner bottom surface of the filter cavity 3. Two connecting pipes 18 are symmetrically installed on the lower surface of the mounting frame 4, and the lower end of each connecting pipe 18 is nested with the upper end of the corresponding connecting rod 17. The lower end of each connecting rod 17 is connected to the corresponding scraper 6, and the lower surface of the scraper 6 is in contact with and slidably connected to the inner bottom surface of the filter cavity 3. During the rotation of the mounting frame 4, the scraper 6 is driven to rotate through the connecting pipe 18 and the connecting rod 17, which helps to more thoroughly remove the impurities or the slurry composed of kaolin and water on the inner bottom surface of the filter cavity 3.

[0024] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
