[0002] The recovery of precious metals from spent catalysts is a complex and delicate process involving multiple steps and technologies. Multi-stage filtration is a key step in ensuring high purity and high recovery rates. In multi-stage filtration, at least two filters are connected in series, which is a common method for recovering precious metals from spent catalysts. However, this method involves numerous pipes, meaning there are many potential leak points. When a leak occurs at a pipe connection due to a seal failure, the leaked liquid can easily flow freely, affecting the cleanliness of the working environment. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-stage filtration and separation device for the recovery of precious metals from waste catalysts, so as to solve the problems mentioned in the background art. This utility model realizes the diversion of leaked liquid, which helps to maintain the cleanliness of the working environment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage filtration and separation device for recovering precious metals from waste catalysts, comprising a support frame, within which a first filter and a second filter are arranged vertically. A detachable bottom cylinder is installed at the lower end of both the first and second filters. A detachable top cover is installed at the upper end of both the first and second filters. A connecting pipe, communicating with the bottom cylinder of the first filter, is installed on the upper surface of the top cover of the second filter. An elbow is installed on the upper surface of the top cover of the first filter and the lower surface of the bottom cylinder of the second filter. A limiting member is installed on the support frame to restrict the positions of the first and second filters. Support legs are installed at the four corners of the support frame, and a collection trough is installed between the four support legs. A pipe connector for connecting a drain pipe is installed on one side of the bottom of the collection trough.

[0005] Furthermore, two U-shaped sleeves are installed on each of the two parallel sides of the collection tank, the U-shaped sleeves are fitted onto the support legs, and a support is installed at the middle position of the bottom of the collection tank.

[0006] Furthermore, the limiting component includes a limiting frame, the upper side of the support frame is provided with the limiting frame, the first filter and the second filter are both disposed within the limiting frame, two vertical tubes are symmetrically installed on the lower surface of the limiting frame, a horizontal tube is installed at the lower end of the vertical tube, and the horizontal tube is installed within the support frame.

[0007] Furthermore, a base plate is installed in the lower part of the collection tank. The length and width of the base plate are equal to the length and width of the bottom of the collection tank, respectively. Three studs are arranged in a ring at equal intervals at the bottom of the bottom cylinder. A straight threaded cylinder is threaded to the lower end of the studs. The lower end of the straight threaded cylinder is connected and fixed to the base plate. A notch is opened on the upper surface of the base plate near the pipe joint.

[0008] Furthermore, two support rods are installed on the upper surface of the base plate, and an arc-shaped plate is fixedly connected to the upper end of each of the two support rods. The two arc-shaped plates are arranged between the two base cylinders and are respectively sleeved on the two base cylinders.

[0009] Furthermore, a handle is fixedly connected to the upper end of the stud, and the handle is arranged perpendicular to the stud.

[0010] The beneficial effects of this utility model are:

[0011] 1. When leakage occurs at the joint of the pipeline connecting the first filter and the second filter, the leaked liquid drips into the collection tank. Subsequently, the liquid in the collection tank flows into the collection container through the drain pipe connected to the pipe joint, thereby draining the leaked liquid and helping to maintain the cleanliness of the working environment.

[0012] 2. The first filter and the second filter are set in the limiting frame and the support frame, respectively. Then, arc-shaped plates connected to the bottom plate are fitted on both bottom cylinders. The arc-shaped plates, the limiting frame and the support frame cooperate with each other to restrict the position of the first filter and the second filter. There is no need to use fasteners to restrict the position of the first filter and the second filter, which saves the trouble of fasteners being unable to be disassembled due to moisture and rust.

[0013] 3. Adjust the length of the studs inside the straight threaded cylinder so that all three studs on the lower side of the bottom cylinder are in contact with the bottom of the bottom cylinder. At this time, the bottom cylinder, supported by the support structure formed by the three sets of studs and the straight threaded cylinder, provides balanced support for removing the bottom of the first filter or the bottom of the second filter.

[0014] 4. Install the straight threaded cylinder and support rod on the base plate, and place the base plate in the collection trough. This completes the restriction of the relative position of the straight threaded cylinder, the arc plate and the collection trough, without the need to use bolts or other fasteners to restrict the relative position of the straight threaded cylinder, the arc plate and the collection trough.

Detailed Implementation

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a multi-stage filtration and separation device for recovering precious metals from waste catalysts, comprising a support frame 1, within which a first filter 5 and a second filter 9 are arranged vertically. A detachable bottom cylinder 11 is installed at the lower end of both the first filter 5 and the second filter 9. A detachable top cover 6 is installed at the upper end of both the first filter 5 and the second filter 9. A connecting pipe 8, which communicates with the bottom cylinder 11 of the first filter 5, is installed on the upper surface of the top cover 6 of the second filter 9. All surfaces are equipped with bent pipe heads. A limiting frame 4 is provided on the upper side of the support frame 1. The first filter 5 and the second filter 9 are both set in the limiting frame 4. Two vertical pipes 3 are symmetrically installed on the lower surface of the limiting frame 4. A horizontal pipe 2 is installed at the lower end of the vertical pipe 3. The horizontal pipe 2 is installed in the support frame 1. The horizontal pipe 2 and the vertical pipe 3 cooperate with each other to limit the relative position of the limiting frame 4 and the support frame 1. The limiting frame 4 and the support frame 1 work together to provide two-point support for the first filter 5 and the second filter 9. After the liquid containing the precious metal of the waste catalyst passes through the first filter 5 and the second filter 9, the precious metal of the waste catalyst is filtered and separated.

[0022] See Figures 1-3Support legs 10 are installed at the four corners of the support frame 1, and a collection tank 12 is installed between the four support legs 10. A pipe connector 7 for connecting the drain pipe is installed on one side of the bottom of the collection tank 12. Two U-shaped sleeves 16 are installed on the two parallel sides of the collection tank 12. The U-shaped sleeves 16 are fitted onto the support legs 10. A support 13 is installed at the middle of the bottom of the collection tank 12. The support 13 supports the collection tank 12. The U-shaped sleeves 16 cooperate with the support legs 10 to restrict the position of the collection tank 12. When leakage occurs at the joint of the pipe connecting the first filter 5 and the second filter 9, the leaked liquid drips into the collection tank 12. Then, the liquid in the collection tank 12 flows into the collection container through the drain pipe connected to the pipe connector 7, thereby draining the leaked liquid and helping to maintain the cleanliness of the working environment.

[0023] See Figures 1-3 A base plate 19 is installed at the lower part of the collection tank 12. The length and width of the base plate 19 are equal to the length and width of the bottom of the collection tank 12, respectively. Three studs 15 are arranged in a ring at equal intervals at the bottom of the bottom cylinder 11. The lower end of the stud 15 is threaded to a straight threaded cylinder 14. A handle is fixed to the upper end of the stud 15. The handle is arranged perpendicular to the stud 15. The lower end of the straight threaded cylinder 14 is fixed to the base plate 19. A notch is opened on the upper surface of the base plate 19 near the pipe joint 7. The notch design prevents the base plate 19 from blocking the pipe joint 7. Two support rods 17 are installed on the upper surface of the base plate 19. The upper ends of the two support rods 17 are fixed to arc plates 18. The two arc plates 18 are placed between the two bottom cylinders 11 and are respectively sleeved on the two bottom cylinders 11. The first filter 5 and the second filter 9 are placed in the limiting frame 4 and the support frame 1, respectively. Then, arc plates 18 connected to the base plate 19 are sleeved on the two bottom cylinders 11. 8. Furthermore, the arc plate 18, the limiting frame 4, and the support frame 1 cooperate with each other to restrict the positions of the first filter 5 and the second filter 9. There is no need to use fasteners to restrict the positions of the first filter 5 and the second filter 9, eliminating the trouble of fasteners being unable to be disassembled due to moisture and rust. Adjust the length of the stud 15 in the straight threaded cylinder 14 so that the three studs 15 on the lower side of the bottom cylinder 11 are in contact with the bottom of the bottom cylinder 11. At this time, the bottom cylinder 11, under the support structure formed by the three sets of studs 15 and the straight threaded cylinder 14, provides balanced support for removing the bottom of the first filter 5 or the bottom of the second filter 9. The straight threaded cylinder 14 and the support rod 17 are installed on the bottom plate 19, and the bottom plate 19 is placed in the collection groove 12. This completes the restriction of the relative positions of the straight threaded cylinder 14, the arc plate 18, and the collection groove 12 without the need to use bolts or other fasteners to restrict the relative positions of the straight threaded cylinder 14, the arc plate 18, and the collection groove 12.
