[0036] One embodiment of the present disclosure provides a detachable solid waste catalyst recovery device, which is installed in a waste catalyst cooling tank. Figure 1The waste catalyst cooling tank includes a shell 21 and a lower head 22. The bottom end of the shell 21 is connected to the top end of the lower head 22. A first discharge port 24 is provided at the bottom (e.g., the center of the bottom) of the lower head 22. The first discharge port 24 serves as a catalyst outlet. In addition, a second discharge port 23 may also be provided at the bottom of the lower head 22. The second discharge port 23 serves as an oil outlet. The detachable solid waste catalyst recovery device includes an annular upper conical shell 4, an overall inverted conical middle conical net 5, and an overall inverted conical lower conical net 2, which are sequentially arranged in the shell 21 from top to bottom. The upper conical shell 4 is fixedly connected (e.g., welded) to the circumferential inner wall of the shell 21. The upper portion of the middle conical net 5 is detachably connected to the upper conical shell 4, and the lower portion of the middle conical net 5 is detachably connected to the upper portion of the lower conical net 2, so that the upper conical shell 4, the middle conical net 5, and the lower conical net 2 together form an inverted conical filtering structure. The bottom end of the lower conical net 2 extends into the first discharge port 24. The lower cone net 2 is detachably mounted to the lower head 22 via a lower cone net mounting assembly. The middle cone net 5 is detachably mounted to the housing 21 via a middle cone net mounting assembly.

[0037] In a preferred embodiment of the present disclosure, referring to Figure 2 and Figure 4 The lower cone net installation assembly includes a plurality of lower cone net installation frames, each of which includes a first angle steel support 11, a connecting plate 12, a first oblique angle steel 9, a first pressing plate 10 and a first fastener (e.g., a bolt and a nut). Figure 4 As shown, the first angle steel support 11 can be set at an angle. The lower part of the first angle steel support 11 is fixedly connected (for example, welded) to the lower head 22, and the upper part of the first angle steel support 11 is detachably connected to the lower part of the connecting plate 12. The upper part of the connecting plate 12 is connected (for example, welded) to the first oblique angle steel 9. The first pressure plate 10 presses a part of the lower cone net 2 on the first oblique angle steel 9, and the first fastener detachably connects the first pressure plate 10, the part of the lower cone net 2 and the first oblique angle steel 9. Preferably, the lower cone net mounting assembly also includes a first annular flat steel 7 and a second annular flat steel 8, and the first annular flat steel 7 and the second annular flat steel 8 each (for example, in the circumferential direction) passes through and is fixed (for example, welded) to a plurality of first oblique angle steels 9; the first annular flat steel 7 and the second annular flat steel 8 respectively support the circumferential outer wall of the lower cone net 2, for example, as Figure 1 As shown, the first annular flat steel 7 supports the upper circumferential outer wall of the lower conical screen 2, while the second annular flat steel 8 supports the lower circumferential outer wall of the lower conical screen 2. Thus, the lower conical screen 2 is pressed against the rigid first oblique angle steel 9 via the first pressing plate 10 and is circumferentially supported and reinforced by the first annular flat steel 7 and the second annular flat steel 8. This ensures that the lower conical screen 2 is securely and reliably installed, effectively withstanding the impact of the fluid medium without collapse or damage. This enhances its durability and service life, ensuring the continuous filtration and recovery of spent catalyst.

[0038] In a preferred embodiment of the present disclosure, referring to Figure 2 The lower cone net 2 includes a plurality of first subnets adjacent to each other, and the plurality of first subnets are spliced ​​together to form an inverted cone-shaped (for example, an inverted truncated cone-shaped) lower cone net 2. The material of the first subnet can be S30403 stainless steel. The two adjacent first subnets are docked on the first oblique angle steel 9 and pressed on the first oblique angle steel 9 by the first pressing plate 10 at the docking position, so that the first fastener can detachably connect the first pressing plate 10, the two adjacent first subnets and the first oblique angle steel 9 at the docking position. Preferably, as Figure 2 As shown, there may be four first subnets, and each first subnet may be in a fan-shaped ring shape; accordingly, there may be four lower cone net mounting frames.

[0039] In a preferred embodiment of the present disclosure, Figure 4 and Figure 5 As shown, the upper portion of the first angle steel support 11 and the lower portion of the connecting plate 12 are detachably connected by a second fastener (eg, a bolt 14 and a nut 13 ).

[0040] In a preferred embodiment of the present disclosure, the bottom end of the lower cone net 2 is connected (for example, welded) to a cylinder 1, and the cylinder 1 is located in the first discharge port 24, so that the catalyst can flow directly into the cylinder 1 through the lower cone net 2 and enter the first discharge port 24, avoiding the catalyst from flowing into other discharge ports (for example, oil outlets) through the gap between the bottom end of the lower cone net 2 and the first discharge port 24, which may cause a decrease in catalyst recovery efficiency and contamination of other recyclables (for example, oil).

[0041] In a preferred embodiment of the present disclosure, referring to Figure 2 、 Figure 8 、 Figure 9 and Figure 10 The intermediate cone net installation assembly includes a plurality of intermediate cone net installation frames 3, each of which includes a second angle steel support 16, a third angle steel support 15, a second oblique angle steel 17, a second pressing plate 6 and a third fastener. Figure 8 As shown, the second angle steel support 16 and the third angle steel support 15 of the same intermediate cone net mounting frame 3 can be arranged in parallel. One end of the second angle steel support 16 and one end of the third angle steel support 15 are each connected to the inner wall of the shell 21 through a pad 20, and the other end of the second angle steel support 16 and the other end of the third angle steel support 15 are respectively connected (for example, welded) to the upper and lower parts of the second oblique angle steel 17 to fix and support the second oblique angle steel 17; the second pressing plate 6 presses a part of the intermediate cone net 5 on the second oblique angle steel 17, and the third fastener detachably connects the second pressing plate 6, the part of the intermediate cone net 5 and the second oblique angle steel 17. Preferably, as Figure 8 and Figure 10 As shown, one end of the second angle steel support 16 and one end of the third angle steel support 15 are respectively welded to one side of the corresponding backing plate 20, and the other side of the backing plate 20 is welded to the inner wall of the shell 21. Preferably, the intermediate cone net installation assembly further includes a third annular flat steel 18 and a fourth annular flat steel 19, each of which (for example, in the circumferential direction) passes through and is fixed (for example, welded) to the plurality of second oblique angle steels 17; the third annular flat steel 18 and the fourth annular flat steel 19 respectively support the circumferential outer wall of the intermediate cone net 5, for example, Figure 1 and Figure 8 As shown, the third annular flat steel 18 supports the circumferential outer wall of the upper middle portion of the middle cone 5, and the fourth annular flat steel 19 supports the circumferential outer wall of the lower middle portion of the middle cone 5. Thus, the middle cone 5 is pressed against the rigid second oblique angle steel 17 via the second pressure plate 6 and circumferentially supported and reinforced by the third annular flat steel 18 and the fourth annular flat steel 19. This ensures a secure and reliable installation of the middle cone 5, effectively withstanding the impact of the fluid medium without collapse or damage. This enhances its durability and service life, ensuring continuous filtration and recovery of spent catalyst.

[0042] In a preferred embodiment of the present disclosure, the first annular flat steel 7, the second annular flat steel 8, the third annular flat steel 18, the fourth annular flat steel 19, the first oblique angle steel 9 and the second oblique angle steel 17 may all be made of S30403 stainless steel. The shell 21 may be made of carbon steel.

[0043] In a preferred embodiment of the present disclosure, referring to Figure 2 、 Figure 6 and Figure 7 The middle cone net 5 includes a plurality of second subnets adjacent to each other, and the plurality of second subnets are spliced ​​together to form an inverted cone-shaped (for example, an inverted truncated cone-shaped) middle cone net 5. The material of the second subnet can be S30403 stainless steel. The two adjacent second subnets are butted on the second oblique angle steel 17 and pressed on the second oblique angle steel 17 by the second pressing plate 6 at the butting position, so that the third fastener can detachably connect the second pressing plate 6, the two adjacent second subnets and the second oblique angle steel 17 at the butting position; for example, Figure 3 、 Figure 6 and Figure 7 As shown, the third fastener includes a bolt 14 and a nut 13, which detachably connect the second pressing plate 6, the two adjacent second subnets and the second oblique angle steel 17 at the docking position of the two adjacent second subnets. Figure 2 As shown, there may be 9 second subnets, and each second subnet may be in a fan-shaped ring shape; accordingly, there may be 9 intermediate cone network mounting frames 3.

[0044] In a preferred embodiment of the present disclosure, Figure 1 As shown, the lower portion of the middle cone screen 5 and the upper portion of the lower cone screen 2 partially overlap on each first oblique angle steel 9. Preferably, the second pressing plate 6 presses the overlapping portion between the lower portion of the middle cone screen 5 and the upper portion of the lower cone screen 2 onto the corresponding first oblique angle steel 9, and can selectively detachably connect the overlapping portion to the first oblique angle steel 9 via fasteners (e.g., bolts and nuts), thereby ensuring a tight connection between the middle cone screen 5 and the lower cone screen 2, thereby ensuring efficient filtration without leaking waste from the connection between the middle cone screen 5 and the lower cone screen 2.

[0045] During use, a fluid medium (e.g., a mixture of oil and catalyst) is injected into the waste catalyst cooling tank through a fluid medium inlet provided on one side of the waste catalyst cooling tank. It then flows downward through the detachable solid waste catalyst recovery device according to one embodiment of the present disclosure, where it is filtered by the middle cone mesh 5 and the lower cone mesh 2. The filtered waste catalyst particles are then recovered onto the middle cone mesh 5 and the lower cone mesh 2. This prevents waste catalyst from being discharged from outlets other than the first outlet 24 (e.g., the second outlet (oil outlet) 23), thereby improving waste catalyst recovery efficiency. Furthermore, by reducing the waste catalyst content in the oil, oil contamination is reduced, thereby improving the quality of the oil discharged from the second outlet 23. Both the middle cone mesh 5 and the lower cone mesh 2 have an overall inverted conical shape. The upper portion of the middle cone mesh 5 is connected to the annular upper cone shell 4, allowing the middle cone mesh 5 to be fully extended without adhesion, thereby fully receiving and filtering the fluid medium and ensuring excellent filtration results. Furthermore, the middle cone screen 5 and the lower cone screen 2 are detachably connected to each other and to other components (e.g., the upper cone shell 4, the housing 21, and the lower end cap 22), making them easy to disassemble, install, and replace. Furthermore, the middle cone screen 5 and the lower cone screen 2 are each composed of multiple annular subnets, each of which can be individually removed and installed. The size of each subnet can be designed to be relatively small, allowing the subnets with attached spent catalyst to be removed and removed through the hand port of the spent catalyst cooling tank, allowing the spent catalyst to be recovered from the subnets, achieving the goal of recycling waste materials.
