Description

Technical Field

[0001] This invention belongs to the field of vacuum filtration equipment and relates to a filtration mechanism. Background Technology

[0002] A vacuum filtration vessel, also known as a filtration reactor or filtration reaction vessel, is commonly used in the chemical industry. Its purpose is to accelerate solid-liquid separation. The main structure includes a vessel body, a discharge channel connected to the bottom of the vessel body, and a filter layer located within the discharge channel. During filtration, a porous support plate supports the filter layer, and the bottom of the discharge channel is under negative pressure. Therefore, under the influence of the pressure difference between the top and bottom of the liquid and the liquid's own weight, the liquid can pass through the filter layer quickly, thus achieving solid-liquid separation.

[0003] Currently, in actual use, a scraper is used to scrape the solids on the filter layer, thereby removing some of the solids that are directly opposite the holes in the support plate. This can improve the filtration speed to a certain extent. However, some smaller particles may become embedded in the filter layer, resulting in lower filtration efficiency. Summary of the Invention

When both the first support blocks and the second support blocks are at their highest height, the tops of the first support blocks and the second support blocks are at the same height, and the tops of the first support blocks and the second support blocks form a support plane. The shape of the support plane matches the shape of the top opening of the main cylinder.

[0009] A compression ring, wherein the compression ring is annular;

[0010] The filter layer has its bottom attached to the top of the support plane, and its edge is located between the clamping ring and the pressure ring.

A second integral component is horizontally arranged at the bottom of all the fifth integral components in the same row. Both ends of the second integral component are vertically and movably connected to the inner wall of the main cylinder.

[0017] The present invention is further configured such that a plurality of support plates are horizontally arranged on the inner wall of the main cylinder, and the first lifting mechanism includes a first elastic member that is vertically arranged on the top of the support plate and is continuously in an extended state. The bottom of the first elastic member is fixedly connected to the support plate, and the top is fixedly connected to the end of the first integral member. Both ends of the first integral member are connected to the first elastic member.

[0018] The bottom of the first integral component is vertically provided with a first raised part with a rectangular longitudinal section and a first lower part with a right-angled triangle longitudinal section. The first lower part is located on the X side of the first raised part. One right-angled side of the first lower part is connected to one end of the first raised part, and the other right-angled side is connected to the bottom of the first integral component. The bottom end of the first lower part is at the same height as the bottom of the first raised part.

[0019] It also includes a horizontally oriented drive column, which is externally connected to a drive mechanism for driving the drive column to move. The drive column moves against the lower side of the first raised part or the lower side of the first lowered part.

[0020] The present invention is further configured such that the second lifting mechanism includes a second elastic member that is vertically disposed on the top of the support plate and is continuously in an extended state, the bottom of the second elastic member is fixedly connected to the support plate, the top is fixedly connected to the end of the second integral member, and both ends of the second integral member are connected to the second elastic member.

[0021] The bottom of the second integral component is vertically provided with a second raised part with a rectangular longitudinal section and a second lower part with a right-angled triangular longitudinal section. The second lower part is located on the -X side of the second raised part. One right-angled side of the second lower part is connected to one end of the second raised part, and the other right-angled side is connected to the bottom of the second integral component. The bottom of the second lower part is at the same height as the bottom of the second raised part. The drive column moves against the lower side of the second raised part or the lower side of the second lower part.

[0022] When the drive column abuts against the lower side of the first descending part, the drive column abuts against the lower side of the second rising part; when the drive column abuts against the lower side of the second descending part, the drive column abuts against the lower side of the first rising part.

[0023] The present invention is further configured such that each of the first integral components has two first descending portions and two first rising portions at its bottom, and each of the second integral components has two second descending portions and two second rising portions at its bottom. Two drive columns are arranged in parallel. Each drive column includes a fixed rod and a rotating cylinder rotatably connected to the outer wall of the fixed rod. Each rotating cylinder can act on the first descending portion, the first rising portion, the second descending portion, and the second rising portion in the same column.

[0024] The present invention is further configured such that two sliding rails are horizontally parallel to each other on both inner walls of the main cylinder, and a sliding bar is horizontally movably arranged between the two sliding rails on the same side. Both ends of the two fixed rods are fixedly connected to the two sliding bars, and the sliding bar moves through the side of the main cylinder.

[0025] A connecting part is provided between the two sliding bars located at the ends of the main cylinder body, and a drive cylinder or electric push rod for driving the connecting part to move is connected to the connecting part.

[0026] The present invention is further configured such that a connecting ring is horizontally arranged on the outer side of the clamping ring, a mating ring is horizontally arranged on the outer side of the pressing ring, the lower side of the mating ring is attached to the upper side of the connecting ring, and a plurality of positioning holes are vertically provided through the connecting ring and the mating ring.

[0027] Compared with the prior art, the present invention provides a filtration mechanism. When in use, this invention requires the cooperation of an upper container for holding the solution, such as a filter kettle or a vacuum filter kettle. Secondly, the bottom opening of the upper container matches the opening at the top of the main cylinder, meaning the bottom cross-section of the upper container is also rectangular. During filtration or vacuum filtration, the top of the main cylinder connects to the bottom of the container, allowing the solid-liquid mixture inside the container to be filtered through the filter layer. Simultaneously, depending on the actual situation, an air extraction structure can be set at the bottom of the main cylinder to create negative pressure, thereby accelerating filtration. Furthermore, a stirring rod and stirring blades are set at the top of the filter layer to accelerate filtration or vacuum filtration. Since the top of the main cylinder and the filter layer are rectangular, there are several stirring blades, each made of elastic material and maintaining a C-shape. During stirring, the bottom of the stirring blades moves and adheres to the filter layer, while the edges of the stirring blades move and abut against the inner wall of the clamping ring. Because the stirring blades are long enough and elastic, they can act on the entire filter layer during the rotation of the stirring rod, thus maintaining the efficiency of filtration or vacuum filtration.

[0028] The support plane at the bottom of the filter layer is formed by all the first and second support blocks; however, during the filtration process, most of the time only the first or second support block supports the filter layer, and only when the mode is changed will the first and second support blocks support the filter layer simultaneously.

[0029] During the filtration process, at one stage, all the first support blocks descend below the second support blocks, forming a mosaic-like pattern that fully supports the filter layer, ensuring effective filtration. Similarly, at another stage, all the second support blocks descend below the first support blocks, again forming a mosaic-like pattern and providing full support for the filter layer. Therefore, whether only the first or second support blocks support the filter layer, it is adequately supported. However, when only the second support blocks support the filter layer, the area above the first support blocks filters better; similarly, when only the first support blocks support the filter layer, the area above the second support blocks filters better. Furthermore, even if smaller particles become embedded in the filter layer, resulting in lower filtration efficiency, the overall filtration efficiency and effect are maintained because the entire filter layer is capable of filtering. Additionally, since the filter layer filters almost its entire surface, its utilization rate is higher, and its operating cost is lower. Attached Figure Description

[0057] Wherein, a is 0 or a positive integer, and n is an integer ≥ 2.

[0058] The top of both ends of the first integral component 11 is vertically provided with a first stabilizing plate 16. The first stabilizing plate 16 is movably attached to the inner wall of the main cylinder 1. Several pairs of first stabilizing strips 17 and second stabilizing strips 18 are provided on the inner wall of the main cylinder 1. The two sides of the first stabilizing plate 16 are movably attached to the first stabilizing strip 17 and the second stabilizing strip 18, respectively.

[0059] The top of both ends of the second integral component 15 are vertically provided with a second stabilizing plate 19. The second stabilizing plate 19 is movably attached to the inner wall of the main cylinder 1. The inner wall of the main cylinder 1 is also vertically provided with a plurality of third stabilizing strips 20.

[0060] The inner wall of the main cylinder 1 is horizontally provided with a plurality of support plates 21. The first lifting mechanism includes a first elastic member 22 that is vertically provided on the top of the support plate 21 and is continuously in an extended state. The bottom of the first elastic member 22 is fixedly connected to the support plate 21, and the top is fixedly connected to the end of the first integral member 11.

[0063] The second lifting mechanism includes a second elastic member 26 that is vertically disposed on the top of the support plate 21 and is continuously in an extended state. The bottom of the second elastic member 26 is fixedly connected to the support plate 21, and the top is fixedly connected to the end of the second integral member 15. Both ends of the second integral member 15 are connected to the second elastic member 26.

[0064] The bottom of the second integral component 15 is vertically provided with a second rising part 27 with a rectangular longitudinal section and a second descending part 28 with a right-angled triangular longitudinal section. The second descending part 28 is located on the -X side of the second rising part 27. One right-angled side of the second descending part 28 is connected to one end of the second rising part 27, and the other right-angled side is connected to the bottom of the second integral component 15. The bottom of the second descending part 28 is at the same height as the bottom of the second rising part 27. The driving column 25 movably abuts against the lower side of the second rising part 27 or the lower side of the second descending part 28.

[0065] When the drive column 25 abuts against the lower side of the first descending part 24, the drive column 25 abuts against the lower side of the second rising part 27; when the drive column 25 abuts against the lower side of the second descending part 28, the drive column 25 abuts against the lower side of the first rising part 23.

[0066] Each of the first integral components 11 has two first descending portions 24 and two first rising portions 23 at its bottom. Each of the second integral components 15 has two second descending portions 28 and two second rising portions 27 at its bottom. Two drive columns 25 are arranged in parallel. Each drive column 25 includes a fixed rod 25a and a rotating cylinder 25b rotatably connected to the outer wall of the fixed rod 25a. Each rotating cylinder 25b can act on the first descending portions 24, the first rising portions 23, the second descending portions 28 and the second rising portions 27 in the same row.

[0067] The inner walls on both sides of the main cylinder 1 are provided with two horizontally parallel sliding rails 29. A sliding bar 30 is horizontally movably arranged between the two sliding rails 29 on the same side. The two ends of the two fixed rods 25a are fixedly connected to the two sliding bars 30. The sliding bar 30 moves through the side of the main cylinder 1.

[0068] A connecting part 31 is provided between the ends of the two sliding bars 30 located outside the main cylinder 1. A drive cylinder or electric push rod for driving the connecting part 31 is connected to the connecting part 31.

[0069] A connecting ring 32 is horizontally arranged on the outer side of the clamping ring 2, and a mating ring 33 is horizontally arranged on the outer side of the pressing ring 5. The lower side of the mating ring 33 is attached to the upper side of the connecting ring 32, and a plurality of positioning holes 34 are vertically opened through the connecting ring 32 and the mating ring 33.

[0070] The present invention provides a filtration mechanism that, when used, requires the cooperation of an upper container for holding the solution, such as a filter kettle or a vacuum filter kettle. Furthermore, the bottom opening of the upper container matches the top opening of the main cylinder 1, meaning the bottom cross-section of the upper container is also rectangular. During filtration or vacuum filtration, after the top of the main cylinder 1 connects with the bottom of the container, the solid-liquid mixture inside the container is filtered through the filter layer 6. Simultaneously, depending on the actual situation, an air extraction structure can be provided at the bottom of the main cylinder 1 to create negative pressure at the bottom of the main cylinder 1, thereby accelerating filtration. A stirring rod and stirring blades are provided on the top of the filter layer 6 to accelerate filtration or vacuum filtration. Since the top of the main cylinder 1 and the filter layer 6 are rectangular, there are several stirring blades, each made of elastic material and maintaining a C-shape. During stirring, the bottom of the stirring blades moves and adheres to the filter layer 6, and the edges of the stirring blades move and abut against the inner wall of the clamping ring 5. Because the stirring blades are long enough and elastic, they can act on the entire filter layer 6 during the rotation of the stirring rod, thereby maintaining the efficiency of filtration or vacuum filtration.

[0071] The support plane at the bottom of the filter layer 6 is formed by all the first support blocks 3 and the second support blocks 4; however, during the filtration process, most of the time only the first support block 3 or the second support block 4 supports the filter layer 6, and only when the mode is changed will the first support block 3 and the second support block 4 support the filter layer 6 at the same time.

[0072] During the filtration process, at one stage, all the first support blocks 3 descend below the second support blocks 4. At this time, all the second support blocks 4 form a mosaic-like shape, providing comprehensive support for the filter layer 6, thus ensuring thorough filtration. In another stage, all the second support blocks 4 descend below the first support blocks 3. At this time, all the first support blocks 3 also form a mosaic-like shape, providing comprehensive support for the filter layer 6, thus ensuring thorough filtration. Therefore, whether only the first support blocks 3 or only the second support blocks 4 support the filter layer 6, the filter layer 6 is adequately supported. However, when only the second support blocks 4 support the filter layer 6, the filter layer 6 above the first support blocks 3 can perform better filtration; similarly, when only the first support blocks 3 support the filter layer 6, the filter layer 6 above the second support blocks 4 can perform better filtration. Furthermore, even if small particles become embedded in the filter layer 6, resulting in lower filtration efficiency, the overall filtration efficiency and effect are still maintained because the entire filter layer 6 can perform filtration. Meanwhile, since the filter layer 6 can filter almost the entire plane, the filter layer 6 has a higher utilization rate and lower operating cost.

[0073] When the first lifting mechanism and the second lifting mechanism control the first support block 3 and the second support block 4 to lift, they simultaneously control all the first support blocks 3 and the second support blocks 4 in the entire main cylinder 1 to move synchronously.

[0074] During the filtration process, if the second support block 4 supports the filter layer 6 and the first support block 3 is lower than the second support block 4, the top of the rotating cylinder 25b abuts against the lower side of the first descending part 24 and the lower side of the second rising part 27. That is, under the action of the rotating cylinder 25b, the second rising part 27 and the second integral part 15 are kept at the highest height. Under the pulling force of the rotating cylinder 25b and the first elastic member 22, the height of the first integral part 11 is reduced, and the heights of the first integral part 9, the second integral part 10, the first support column 7 and the first support block 3 are also reduced, and the first support block 3 is lower than the second support block 4. At this time, the filtered or vacuum-filtered liquid, after passing the side of the second support block 4, can flow directly downward through the second support column 8. That is, the liquid flow channel is open, and filtration or vacuum-filtration can proceed normally.

[0075] When the first support block 3 supporting the filter layer 6 needs to be replaced after filtering for a period of time, the connecting part 31 moves towards the second descending part 28 under the drive of conventional equipment such as electric push rod, cylinder or hydraulic cylinder; during this movement, the rotating cylinder 25b first raises the first integral part 11 through the first descending part 24. When the rotating cylinder 25b acts on the bottom of the first rising part 23 and the second rising part 27 at the same time, the tops of the first support block 3 and the second support block 4 are at the same height; then the rotating cylinder 25b continues to move until it moves to the second descending part 28, and the lower side of the second descending part 28 abuts against the upper side of the rotating cylinder 25b;

[0076] When the rotating cylinder 25b stops moving, its upper side or top abuts against the bottom of the first rising part 23 and simultaneously against the lower side of the second falling part 28 (due to the downward pulling force of the second elastic member 26). Thus, the filter layer 6 is supported by the top of the first support block 3. At the same time, the bottom of the second support block 4 is lower than the bottom of the first support block 3, allowing the liquid to flow downward normally. This achieves the adjustment of the structure supporting the filter layer 6. In the actual filtration or vacuum filtration process, the support of the filter layer 6 by the first support block 3 and the second support block 4 can be adjusted multiple times.

[0077] Both ends of the first integral component 11 are subjected to the tension of the first elastic member 22, and both ends of the second integral component 15 are subjected to the tension of the second elastic member 26. However, since the first integral component 11 has sheet-like first stabilizing plates 16 at both ends, and the second integral component 15 has sheet-like second stabilizing plates 19 at both ends, and the first stabilizing plates 16 and the second stabilizing plates 19 are limited by the first stabilizing bar 17, the second stabilizing bar 18 and the third stabilizing bar 20, the first integral component 11 and the second integral component 15 can only move vertically and stably. Moreover, the two rotating cylinders 25b act simultaneously on all the first rising parts 23, the first falling parts 24, the second rising parts 27 and the second falling parts 28, which can further improve the stability of the lifting of the first support block 3 and the second support block 4.

[0078] After placing the filter layer 6 on the support plane, place the clamping ring 5 on the top of the main cylinder 1. At this time, the edge of the filter layer 6 is located between the clamping ring 5 and the clamping ring 2, but it is not completely fixed. Then, connect the main cylinder 1 to the bottom of the upper container. At this time, the outer side of the bottom of the upper container also has a flange with holes. After aligning the positions of the mating ring 33, the connecting ring 32 and the flange, pass the screw through the flange and the positioning hole 34, and finally use the nut to fix the connecting ring 32, the mating ring 33 and the flange.
