Description

Technical Field

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

[0002] Kaolin 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 on the whiteness, fineness, and chemical stability of kaolin. Filtration is a key step in achieving these indicators.

[0003] When using the existing rapid filter for kaolin processing, impurities are filtered through the filter plate, first discharging the slurry composed of kaolin and water, and then the impurities are discharged after the filtration process is completed. However, there are still the following technical problems, such as:

[0004] Existing rapid filters for kaolin processing have poor filtration efficiency because the filter screens thereon are mostly fixedly installed, which results in insufficient efficiency of the existing filters when filtering kaolin. For example, publication number CN219765967U discloses a kaolin filtering device which is connected by a fixed motor, a fixed shaft, and a fixed plate so that the filter plate can be rotated during discharge. This only facilitates discharge but does not improve the efficiency and effect of the filter plate filtration.

[0005] In addition, when impurities need to be discharged, the above-mentioned prior art uses a fixed motor to rotate the filter plate, which increases the energy consumption required by the entire device and is not conducive to energy conservation and emission reduction.

[0006] Therefore, a rapid filter for kaolin processing is needed to solve the above problems. Summary of the Invention

[0012] Preferably, the upper surface of the transmission disc is provided with a prismatic protrusion coaxial therewith, and the lower surface of the connection disc is provided with a prismatic groove, and the prismatic protrusion and the prismatic groove are slidably engaged with each other.

[0013] Preferably, the top supporting mechanism includes a top supporting rod arranged between two shaft columns, and pressure wheels are provided at both ends of the top supporting rod, and the two pressure wheels are respectively connected to the two shaft columns in a rolling manner, and two sleeves are movably nested on the top supporting rod, and a tension spring nested on the outside of the top supporting rod is provided between the two sleeves, and the inner bottom surface of the mounting frame is connected to the two sliding frames through two slider groove assemblies, and the two sliding frames are symmetrically arranged about the axis center of the mounting frame, and the lower surface of each sleeve is axially connected to the corresponding upper end of the top supporting arm, and the lower end of the top supporting arm is axially connected to the corresponding end of the sliding frame.

[0014] Preferably, both sliding frames are provided with limiting holes, and one end of a corresponding limiting shaft is movably inserted into each limiting hole, and the other end of the limiting shaft is fixedly connected to the opposite side of the sliding frame.

[0015] Preferably, the top support mechanism also includes a supporting gear fixedly connected to the upper surface of the mounting seat, and the supporting gear is coaxially arranged with the bump ring assembly, the lower surface bearing of the mounting frame passes through two shafts, and the upper and lower ends of each shaft are respectively keyed to a driven gear and a follower gear, the follower gear is meshedly connected to the outer side of the supporting gear, and the inner side of the sliding frame is evenly distributed with fixed teeth, and the fixed teeth are meshedly connected to the corresponding driven gear.

[0016] Preferably, a T-shaped rod is provided on the opposite side of the two sliding frames, and movable teeth are movably nested on the T-shaped rod. 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 outer side of the middle part of the T-shaped rod.

[0017] Preferably, the gear ratio between the supporting gear and the driven gear is not less than 5, so that when the supporting gear rotates at a relatively low speed, the driven gear rotates at a high speed.

In addition, the scraper can improve the discharge effect during discharge:

[0020] 1. When the servo motor drives the transmission disc to rotate, the connecting disc can drive the mounting frame to rotate, thereby rotating the filter plate installed on the mounting frame. In addition, the right-angled triangular prism blocks arranged on the upper surface of the bump ring assembly and the lower surface of the connecting disc can make the mounting frame bump up and down during the rotation process, thereby causing the filter plate installed thereon to vibrate, which is beneficial to improving the filtration efficiency and effect of the filter plate;

[0021] 2. When the servo motor is running, it drives the mounting frame to rotate, causing the follower gear to rotate around the supporting gear. At this time, the driven gear is driven to rotate through the shaft rod, prompting the sliding frame to move, causing the two sets to move away from each other, causing the tension spring between the two to generate elastic potential energy, and causing the support rod to move downward, and then the two shaft columns are pressed by the two pressure wheels. 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 filtering operation can be carried out through the two filter plates. When the servo motor stops running, the tension spring resets the support rod, causing it to move upward. At this time, the two filter plates will rotate in opposite directions under the action of their own gravity, and the impurities on the filter plates can be automatically discharged, avoiding the addition of additional motors and other energy-consuming components.

[0022] 3. Through the connecting rod and the connecting pipe, the scraper can rotate together with the mounting frame, and then during the discharge process, the scraper can discharge impurities or filtered kaolin mud more thoroughly out of the filter cavity. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1-11 , the present invention provides the following technical solutions:

[0037] Embodiment 1: In order to solve the problem that the rapid filter for kaolin processing in the past could not improve the efficiency and effect of filtration during use, the following technical solution is provided, specifically, a rapid filter for kaolin processing, comprising a support base 1 and a support arm 2 mounted thereon at equal angles, the upper end of the support arm 2 is fixedly connected to a filter cavity 3 coaxial with the support base 1, the inner bottom surface of the filter cavity 3 is provided with a mounting base 15, and a servo motor 16 is installed inside the mounting base 15, the shaft end of the servo motor 16 passes through the top of the mounting base 15, the interior of the filter cavity 3 is provided with a mounting frame 4, 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.

[0038] The bump transmission mechanism includes a transmission disk 19 which is coaxially keyed to the shaft end of the servo motor 16, and the upper end of the transmission disk 19 is movably extended into the lower end of the connecting disk 31, and the upper end of the connecting disk 31 is coaxially fixedly connected to the lower surface of the mounting frame 4, and the transmission disk 19 bearing is connected to the inner side of the bump ring assembly 20, and the bump ring assembly 20 is fixedly connected to the upper surface of the mounting seat 15, and the upper surface of the bump ring assembly 20 and the lower surface of the connecting disk 31 are provided with right-angled triangular prism blocks at equal angles, and the right-angled triangular prism blocks between the two are arranged one by one, and the inclined surfaces of the corresponding right-angled triangular prism blocks are arranged relative to each other, and the upper surface of the transmission disk 19 is provided with a prismatic protrusion coaxial therewith, and the lower surface of the connecting disk 31 is provided with a prismatic groove, and the prismatic protrusion It is connected with the prismatic groove by sliding engagement. When in use, the operation of the servo motor 16 causes the transmission disc 19 to rotate. The prismatic protrusion and the prismatic groove are connected by sliding engagement, so that the transmission disc 19 can drive the connecting disc 31 to rotate synchronously, and does not affect the relative movement of the connecting disc 31 driven by the transmission disc 19. In the process of rotation of the two, the connecting disc 31 can be prompted to move back and forth relative to the transmission disc 19 through the corresponding right-angled triangular prism blocks, so that the mounting frame 4 vibrates back and forth in the process of rotation. Since the mounting frame 4 is connected to the filter plate 5 through the shaft column 8, the servo motor 16 will cause the filter plate 5 to vibrate up and down while rotating during operation, thereby helping to improve the efficiency and effect of filtration.

[0039] Example 2: In order to solve the problem that in the past, when the rapid filter used in kaolin processing needs to discharge impurities, it is necessary to use additional motors and other energy-consuming components to rotate the filter plate, thereby increasing energy consumption, the following technical solution is provided. Specifically, the interior of the mounting frame 4 is connected to the upper surface of the mounting seat 15 through a top support mechanism, and a baffle 7 is installed on the top of the mounting frame 4, so that the two corners of the upper end of the mounting frame 4 are exposed with gaps, and the gaps on the two mounting frames 4 are penetrated by shaft columns 8, and the shaft columns 8 are axially connected to the mounting frame 4 so that the shaft columns 8 can rotate relative to the mounting frame 4, and the top of each shaft column 8 is connected to a filter plate 5, and the two shaft columns 8 are supported by the top support mechanism, and the center of gravity of the filter plate 5 is close to its outer edge.

[0040] The top supporting mechanism includes a top supporting rod 10 arranged between the two shaft columns 8, and a pressure wheel 9 is provided at both ends of the top supporting rod 10, and the two pressure wheels 9 are respectively connected to the two shaft columns 8 in a rolling manner. Two sleeves 11 are movably nested on the top supporting rod 10, and a tension spring 12 is provided between the two sleeves 11 and nested on the outside of the top supporting rod 10. The inner bottom surface of the mounting frame 4 is connected to the two sliding frames 23 respectively through two slider slide groove assemblies 24, and the two sliding frames 23 are symmetrically arranged about the axis center of the mounting frame 4. The lower surface of each sleeve 11 is axially connected to the upper end of the corresponding top supporting arm 13, and the lower end of the top supporting arm 13 is axially connected to the end of the corresponding sliding frame 23. The movable frame 23 is provided with a limiting hole, and one end of the corresponding limiting shaft 25 is movably extended into each limiting hole, and the other end of the limiting shaft 25 is fixedly connected to the side of the opposite sliding frame 23. The top support mechanism also includes a support gear 21 fixedly connected to the upper surface of the mounting seat 15, and the support gear 21 is coaxially arranged with the bump ring assembly 20. The lower surface bearing of the mounting frame 4 passes through two shafts 14, and the upper and lower ends of each shaft 14 are respectively keyed to a driven gear 26 and a follower gear 22. The follower gear 22 is meshed with the outer side of the support gear 21. The inner side of the sliding frame 23 is evenly distributed with fixed teeth 27, and the fixed teeth 27 are aligned with the corresponding driven gears. The wheels 26 are meshed and connected, and a T-shaped rod 28 is provided on the opposite side of the two sliding frames 23, and a movable tooth 29 is movably nested on the T-shaped rod 28. A return spring 30 is provided between one side of the movable tooth 29 and the corresponding side of the sliding frame 23, and between the other side of the movable tooth 29 and the end of the T-shaped rod 28, and the return spring 30 is movably nested on the outside of the middle part of the T-shaped rod 28. When in use, due to the rotation of the mounting frame 4, the follower gear 22 will rotate on the outside of the supporting gear 21, thereby causing the driven gear 26 to drive the sliding frame 23 to move through the fixed tooth 27. In this process, the two sets 11 will move away from each other, thereby causing the tension spring 12 to be Pulling generates elastic potential energy, and also causes the supporting rod 10 to drive the pressure wheel 9 to move downward synchronously, thereby pressing the two shaft columns 8, so that the two shaft columns 8 are parallel to each other. At this point, the two filter plates 5 are spliced together. When the servo motor 16 is no longer 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 due to their own gravity. In this process, the mounting frame 4 will rotate in the opposite direction and vibrate, which can be beneficial to the discharge of impurities on the filter plate 5. Since the two filter plates 5 rotate in opposite directions, there is no need for additional motors and other energy-consuming components, which is beneficial to reducing energy consumption and contributing to energy conservation and emission reduction.

The thickness of the following gear 22 is not greater than 1 / 2 of the thickness of the supporting gear 21, and the thickness of the following gear 22 is greater than the length of the short right-angled side of the triangular prism block, to ensure that the following gear 22 will not be separated from the supporting gear 21 during the up and down reciprocating bumps of the mounting frame 4.

[0042] Example 3: In order to solve the problem that the rapid filter used for kaolin processing in the past could not discharge internal impurities or kaolin mud more thoroughly, the following technical solution is provided. Specifically, the inner bottom surface of the filter cavity 3 is an inverted hollow cone, and the inner bottom surface of the filter cavity 3 is symmetrically provided with two discharge ports 32 running through its two sides, and the lower surface of the mounting frame 4 is symmetrically provided with two connecting pipes 18, and the lower end of each connecting pipe 18 is nested with the upper end of the corresponding connecting rod 17, and 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 and sliding connection with the inner bottom surface of the filter cavity 3. During the rotation of the mounting frame 4, the scraper 6 is driven to rotate by the connecting pipe 18 and the connecting rod 17, which can help to more thoroughly remove impurities or slurry composed of kaolin and water on the inner bottom surface of the filter cavity 3.
