Description

Technical Field

[0001] This invention relates to the field of rotary vacuum filter technology, and more particularly to a rotary vacuum filter with a segmented central platform. Background Technology

[0002] The central platform is a crucial component of the rotary vacuum filter. It supports the internal legs of all platform components (such as the discharge screw, filtrate distributor, washing liquid distributor, anti-fog hood, flushing water, and walkway platform). In traditional rotary vacuum filters, the central platform's spokes are of an integral structure. Under normal circumstances, maintenance of the upper and lower air discs only requires lifting the upper air disc electrically. However, with prolonged operation, corrosion and abrasion of the upper and lower air discs can occur, necessitating their removal for repair or replacement. In such cases, the filter's hoses, central platform, and platform structure must be completely dismantled. This is not only labor-intensive and time-consuming but also significantly delays equipment maintenance, reducing the overall operating rate. Summary of the Invention

[0003] To address the technical problem of time-consuming and labor-intensive disassembly when removing or replacing the upper and lower misaligned air discs in existing technologies, this invention provides a rotary vacuum filter with a segmented central platform.

[0004] This invention discloses a rotary vacuum filter with a segmented central platform, comprising a central column, upper and lower staggered air discs, a flat disc assembly, and a segmented central platform. The segmented central platform includes an inner ring assembly and an outer ring assembly. The inner ring assembly includes a central cylinder, a platform plate, and multiple platform spokes. The multiple platform spokes are radially distributed around the central axis of the central cylinder. The ends of the multiple platform spokes near the central cylinder are all connected to the side wall of the central cylinder. The platform plate is coaxially disposed around the outer periphery of the central cylinder, and the upper surface of the platform plate is coplanar with the upper surface of the central cylinder. The platform plate covers and is connected to the multiple platform spokes. The side of the central cylinder fits against the side wall of the central cylinder, and the central cylinder is set on the central column. The upper and lower staggered air plates are set on the side wall of the central column and located directly below the platform plate. The outer ring assembly includes an outer ring platform and multiple connecting seats. The multiple connecting seats are detachably connected to multiple platform spokes in a one-to-one correspondence. The multiple connecting seats are all located on the side of their corresponding platform spokes away from the central cylinder. The outer ring platform is coaxially set on the outer periphery of the platform plate. The upper surface of the outer ring platform is coplanar with the upper surface of the platform plate. The outer ring platform is located above and connected to the multiple connecting seats. The flat plate assembly is coaxially set on the outer periphery of the outer ring platform with the central cylinder.

[0005] Preferably, the outer ring assembly also includes a platform collection trough, which is coaxially disposed on the outer periphery of the outer ring platform. The upper surface of the platform collection trough is located below the upper surface of the outer ring platform. The side of the platform collection trough near the outer ring platform is connected to the side of the outer ring platform near the platform collection trough. A flat plate assembly is located above the platform collection trough, and a collection scraper is provided on the flat plate assembly near the platform collection trough, with the lower end of the collection scraper inserted into the platform collection trough. Further, the bottom surface of the platform collection trough has a discharge hole, and a discharge pipe is connected to the discharge hole; a rubber pad is provided at the connection between the platform collection trough and the outer ring platform.

[0006] Preferably, the platform plate includes multiple platform panels, which are detachably connected end-to-end on the outer periphery of the central cylinder, and the upper surfaces of the multiple platform panels are all coplanar with the upper surface of the central cylinder. Further, the upper and lower staggered air plates are located below a group of adjacent platform panels within the multiple platform panels.

[0007] Preferably, the upper surface of the outer platform is covered with a steel plate.

[0008] Preferably, the maximum distance from the platform plate to the center cylinder is greater than the maximum distance from the multiple platform spokes to the center cylinder.

[0009] Preferably, any two adjacent platform spokes in the multiple platform spokes are connected by angle steel.

[0010] Preferably, the distance from the multiple platform spokes to the platform plate gradually decreases from the end closest to the central cylinder to the end furthest from the central cylinder.

[0011] Compared with the prior art, the rotary vacuum filter with a segmented central platform of the present invention, by setting multiple platform spokes 13 radially distributed around the central axis of the central cylinder 11, and multiple connecting seats 23 that are detachably connected to the multiple platform spokes 13, facilitates the separation of the inner ring assembly 10 from the outer ring assembly 20 and the removal of the inner ring assembly 10 as a whole. It can remove or replace the upper and lower staggered air plates without dismantling the filter table structure, saving removal or replacement time, reducing the labor intensity of workers, and increasing the start-up rate of the filter.

[0017] In the description of this invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] Please refer to the above. Figures 1 to 3 The present invention provides a rotary vacuum filter with a segmented central platform, the rotary vacuum filter comprising a central column 1, upper and lower staggered air plates 2, a flat plate assembly 3 and a segmented central platform 100.

[0019] The segmented center platform 100 includes an inner ring assembly 10 and an outer ring assembly 20. The outer ring assembly 20 and the inner ring assembly 10 are detachably connected so that the upper and lower misaligned air plates can be removed or replaced by removing only the inner ring assembly 10 without removing the flat plate assembly 3, saving removal or replacement time, reducing the labor intensity of workers, and increasing the start-up rate of the filter.

[0020] The inner ring assembly 10 includes a central cylinder 11, a platform plate 12, and multiple platform spokes 13. The multiple platform spokes 13 are radially distributed around the central axis of the central cylinder 11. The ends of the multiple platform spokes 13 near the central cylinder 11 are connected to the side wall of the central cylinder 11. The platform plate 12 is coaxially disposed around the outer periphery of the central cylinder 11. The upper surface of the platform plate 12 is coplanar with the upper surface of the central cylinder 11. The platform plate 12 covers the multiple platform spokes 13 and is connected to the multiple platform spokes 13. The side of the platform plate 12 near the central cylinder 11 is in contact with the side wall of the central cylinder 11. The central cylinder 11 is disposed on the central column 1. The upper and lower air-displacement discs 2 are disposed on the side wall of the central column 1 and located directly below the platform plate 12, so that the upper and lower air-displacement discs 2 can be removed or replaced by removing the inner ring assembly 10.

[0021] In a preferred embodiment, any two adjacent platform spokes 13 are connected by angle steel, so that the angle steel is used as a tie rod to strengthen and form a stable inner ring frame structure of the central platform.

[0022] The outer ring assembly 20 includes an outer ring platform 21 and multiple connecting seats 22. The multiple connecting seats 22 are detachably connected to multiple platform spokes 13 in a one-to-one correspondence. The multiple connecting seats 23 are all located on the side of their corresponding platform spokes 13 away from the central cylinder 11 to enhance the stability of the segmented central platform 100. The outer ring platform 21 is coaxially disposed on the outer periphery of the platform plate 12. The upper surface of the outer ring platform 21 is coplanar with the upper surface of the platform plate 12. The outer ring platform 21 is located above the multiple connecting seats 23 and connected to the multiple connecting seats 23. The flat plate assembly 3 is coaxially disposed on the outer periphery of the outer ring platform 21 with the central cylinder 11.

[0023] In this embodiment of the rotary vacuum filter, when it is necessary to remove or replace the upper and lower misaligned air discs 2 for major repair or replacement, the outer ring platform 21 is lifted by a crane, the fasteners connecting the platform spokes 13 and their corresponding connecting seats 22 are removed, and the inner ring assembly 10 is removed as a whole, thus allowing the upper and lower misaligned air discs to be dismantled. This eliminates the need to dismantle the flat disc assembly 3, saving time, greatly reducing the labor intensity of workers, and increasing the equipment uptime.

[0024] In a preferred embodiment, the platform plate 12 includes multiple platform panels 121, which are detachably connected end to end on the outer periphery of the central cylinder 11. That is, the platform plate 12 forms a ring structure by splicing multiple platform panels 121. The upper surfaces of the multiple platform panels 121 are all coplanar with the upper surface of the central cylinder 11. Therefore, the upper and lower air discs can be removed or replaced simply by removing the platform panel 121 and platform spokes 13 directly above the upper and lower air discs, thereby further saving removal or replacement time, reducing the labor intensity of workers, and increasing the start-up rate of the filter.

[0025] Furthermore, the upper and lower staggered air plate is located below a group of two adjacent platform spokes 13 among the multiple platform spokes 13. Thus, the upper and lower staggered air plate can be removed or replaced simply by removing the platform panel 121 directly above it, which saves removal or replacement time, reduces labor intensity, and increases the operating rate of the filter.

[0026] In a preferred embodiment, the outer ring assembly 20 further includes a platform collection trough 23, which is coaxially disposed on the outer periphery of the outer ring platform 21. The upper surface of the platform collection trough 23 is located below the upper surface of the outer ring platform 21. The side of the platform collection trough 23 near the outer ring platform 21 is connected to the side of the outer ring platform 21 near the platform collection trough 23. The flat plate assembly 3 is located above the platform collection trough 23. A collection scraper 31 is provided on the flat plate assembly 3 near the platform collection trough 23. The lower end of the collection scraper 31 is inserted into the platform collection trough 23 so that when the flat plate assembly 3 rotates in a circular motion, the collection scraper 31 follows the circular rotation to collect the material in the platform collection trough 23.

[0027] Furthermore, the bottom surface of the platform collection tank 23 is provided with a discharge hole, and a discharge pipe is connected to the discharge hole to discharge the collected material.

[0028] To prevent leakage of materials collected in the platform collection tank 23, a rubber pad is provided at the connection between the platform collection tank 23 and the outer ring platform 21.

[0029] Preferably, the upper surface of the outer ring platform 21 is covered with a steel plate to ensure sufficient strength to support the flat plate assembly 3.

[0030] Preferably, the distance from the multiple platform spokes 13 to the platform plate 12 gradually decreases from the end closest to the central cylinder 11 to the end furthest from the central cylinder 11, so as to ensure the stability of the platform spokes 13, thereby ensuring the stability of the platform plate 12 and the outer ring assembly 20.

[0031] Preferably, the maximum distance from the platform plate 12 to the central cylinder 11 is greater than the maximum distance from the multiple platform spokes 13 to the central cylinder 11, so as to facilitate the disassembly and installation of the connecting seat 22 and the platform spokes 13, and at the same time provide sufficient space for the removal of the upper and lower misaligned air plates 2.

[0032] In actual use, the flat plate assembly 3, platform plate 12, outer ring platform 21, and platform collection tank 23 are all in a circular structure; the end of the flat plate assembly 3 near the segmented central platform 100 is supported on the outer ring platform 21 by a support frame; the flat plate assembly 3 includes a filter plate, a washing liquid distributor, etc., and this application will not describe this part of the structure in detail.

[0033] The present invention discloses a rotary vacuum filter with a segmented central platform. By setting multiple platform spokes 13 radially distributed around the central axis of the central cylinder 11 and multiple connecting seats 23 that are detachably connected to the multiple platform spokes 13, it is easy to separate the inner ring assembly 10 from the outer ring assembly 20 and remove the inner ring assembly 10 as a whole without dismantling the filter table structure. This allows for the removal or replacement of the upper and lower staggered air plates, saving removal or replacement time, reducing the labor intensity of workers, and increasing the start-up rate of the filter.

Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other. It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, any modifications and refinements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
