Description

Technical Field

[0001] The present invention relates to the technical field of cooling and filtering devices, and more specifically, to a cooling and filtering device and a cooling and filtering method for a rhodium catalyst. Background Art

[0002] In the process of rhodium catalyst recovery, filtration is a key separation step to separate the rhodium catalyst in the reaction system from the waste liquid. Usually, solid-liquid separation can be quickly achieved by filtration, laying a foundation for subsequent treatment. For example, when treating rhodium catalyst waste with sodium hydroxide solution, the reaction solution needs to be filtered to remove impurities such as carbonates and hydroxides, and the solid part containing rhodium is retained after filtration for the next extraction step.

[0003] For example, a solid-liquid separation device for a titanium-based catalyst product disclosed in the patent with the patent number CN222489105U. Although the solid-liquid separation device drives the pressing plate to rotate and move down along the threaded connection part when the vertical rod rotates, when the pressing plate moves down, it compresses the mixed product on the top of the filter plate, so that the liquid in the mixed product flows down from the filter plate and is led out through the discharge pipe, while the solid catalyst product remains on the top of the filter plate. As the pressing plate continuously presses down, the liquid in the mixed product will be completely extruded. The cooperation of multiple components can accelerate the solid-liquid separation speed of the catalyst product and improve the separation efficiency. However, in actual use, it does not have the function of cooling the reaction solution, resulting in the filtration treatment of the reaction solution at a relatively high temperature, thus affecting the subsequent treatment.

Specific embodiments

[0024] To further understand the content of the present invention, the present invention will be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present invention and not for limiting it.

[0025] The following is a further detailed description of this embodiment in combination with the attached Figures 1-6 drawings.

[0026] Combined with Figures 1-6 As shown, a cooling and filtering device for a rhodium catalyst in this embodiment includes a processing cylinder 100 with an open upper end. A filter plate 210 is provided inside the processing cylinder 100. A cooling mechanism for cooling the filter plate 210 is provided outside the processing cylinder 100. The cooling mechanism includes a coolant circulation component and a heat dissipation component. The coolant circulation component includes a cooling loop pipe 110 covering the outside of the processing cylinder 100. A plurality of cooling pipes 211 are arranged side by side on the lower side surface of the filter plate 210. The two ends of the cooling pipe 211 are respectively provided with a liquid inlet pipe 212 and a liquid outlet pipe 213 communicating with the cooling loop pipe 110. A liftable piston ring 220 is provided inside the cooling loop pipe 110. An air inlet member that can be opened and closed is provided on the liquid inlet pipe 212 and the liquid outlet pipe 213. The lifting of the piston ring 220 is used to realize the circulation of the coolant through the liquid inlet pipe 212, the cooling pipe 211 and the liquid outlet pipe 213. A first driving member is provided at the bottom of the processing cylinder 100. The first driving member is used to drive the piston ring 220 to lift and lower; The heat dissipation component includes an air duct cylinder 120 covering the outside of the cooling loop pipe 110. The heat dissipation component further includes heat dissipation fins 231 arranged on the outer side wall of the cooling loop pipe 110. The first driving member is used to drive the air flow inside the air duct cylinder 120. The air flow inside the air duct cylinder 120 is also used to blow air to the filter plate 210; A knocking member for knocking the filter plate 210 is provided inside the processing cylinder 100. The first driving member is also used to drive the knocking member to work.

[0027] In this embodiment, the cooling tube 211 is fixedly connected to the lower side of the filter plate 210. The filter plate 210 and the cooling tube 211 are both made of a material with good thermal conductivity. The filter plate 210 is provided with filter holes located between the cooling tubes 211. Therefore, in actual use, the mixed liquid to be treated is placed through the upper end opening of the treatment cylinder 100 onto the filter plate 210, and the mixed liquid is filtered through the filter holes on the filter plate 210. Among them, by setting the coolant circulation component and the heat dissipation component, it is possible to better cool the filter residue on the filter plate 210; The cooling ring pipe 110 is fixed to the outer wall of the treatment cylinder 100 and stores coolant therein. In actual use, the air inlet member and the piston ring 220 are arranged, and the piston ring 220 is driven to rise and fall in the cooling ring pipe 110 by the first driving member. In conjunction with the opening and closing of the air inlet member, the coolant in the cooling ring pipe 110 can be driven to circulate between the liquid inlet pipe 212, the cooling pipe 211, the liquid outlet pipe 213 and the cooling ring pipe 110. Through the heat exchange between the cooling pipe 211 and the filter plate 210, the filter residue on the filter plate 210 can be preferably cooled. In order to cool the cooling liquid after heat exchange so that the cooled cooling liquid can circulate and cool the filter residue on the filter plate 210, the heat dissipation component is provided so that it can dissipate heat from the cooling liquid in the cooling loop 110 to cool the cooling liquid and ensure that the cooling liquid circulates and cools the filter residue; In this embodiment, by setting the air duct tube 120 and the heat dissipation fins 231, in actual use, the heat in the coolant in the cooling ring tube 110 is introduced into the air duct tube 120 through the heat dissipation fins 231. The air flow in the air duct tube 120 can be used to dissipate the heat on the heat dissipation fins 231, thereby cooling the coolant and facilitating the circulation of the coolant.

[0028] During actual use, the first driving member is used to drive the air flow in the air duct tube 120 so as to enable the heat dissipation component to dissipate heat from the coolant.

[0029] Among them, through the setting of the knocking member, the first driving member can drive the knocking member to knock on the filter plate 210 during operation, so that the filter residue on the filter plate 210 is vibrated, thereby promoting the filtering effect of the filter plate 210 on the mixed liquid; at the same time, the air flow in the air duct tube 120 is also used to blow air to the filter plate 210, and can also make the filter residue on the filter plate 210 be turned over, thereby better improving the filtering effect of the filter plate 210 on the mixed liquid.

[0030] In this embodiment, the first driving member includes a rotating shaft 240 rotatably disposed within the air duct cylinder 120. A driving groove 310, which is wavy and connected end to end, is provided on the outer sidewall of the rotating shaft 240. A lifting ring 250 is sleeved outside the rotating shaft 240. Driving posts 501, which are arranged oppositely on the inner wall of the lifting ring 250 and slide within the driving groove 310, are provided. A plurality of support rods 251 are arranged on the outer sidewall of the lifting ring 250. A connecting rod 252, which penetrates through the cooling ring pipe 110 and connects to the piston ring 220, is provided on the support rod 251.

[0031] During the actual use of this embodiment, the connecting rod 252 penetrates through the cooling ring pipe 110 and is connected to the support rod 251, thereby restricting the lifting ring 250 and preventing it from rotating circumferentially. When the rotating shaft 240 rotates, the sidewall of the driving groove 310 can squeeze the driving posts 501, thereby driving the lifting ring 250 to move up and down, and then driving the piston ring 220 to move up and down within the cooling ring pipe 110 to achieve the circulating flow of the coolant. Specifically, the intake member includes a first solenoid valve provided on the liquid inlet pipe 212 and a second solenoid valve provided on the liquid outlet pipe 213. During actual use, when the piston ring 220 moves down within the cooling ring pipe 110, the first solenoid valve on the liquid inlet pipe 212 opens, and the second solenoid valve on the liquid outlet pipe 213 closes. The downward movement of the piston ring 220 can press the cooling liquid into the cooling pipe 211 to cool the filter residue by heat exchange. When the piston ring 220 moves up within the cooling ring pipe 110, the first solenoid valve on the liquid inlet pipe 212 closes, and the second solenoid valve on the liquid outlet pipe 213 opens. The upward movement of the piston ring 220 can suck the cooling liquid in the cooling pipe 211 into the cooling ring pipe 110 to achieve the circulation of the coolant.

[0032] During its actual use, a first trigger switch is provided at the highest point of the driving groove 310, and a second trigger switch is provided at the lowest point of the driving groove 310. Thus, during actual use, when the driving post 501 slides to the highest position, the driving post 501 triggers the first trigger switch. At this time, the first solenoid valve opens and the second solenoid valve closes to allow the coolant to enter the cooling pipe 211. When the driving post 501 slides to the lowest position, the driving post 501 triggers the second trigger switch. At this time, the first solenoid valve closes and the second solenoid valve opens to allow the coolant in the cooling pipe 211 to flow back into the cooling ring pipe 110.

[0033] In this embodiment, an installation frame 260 is provided at the lower opening of the air duct cylinder 120, and a motor 130 for driving the rotation of the rotating shaft 240 is provided on the installation frame 260.

[0034] In this embodiment, through the arrangement of the installation frame 260 and the motor 130, the motor 130 can drive the rotation of the rotating shaft 240 to achieve the circulation of the coolant and cool down the filter residue on the filter plate 210.

[0035] Specifically, in order to install the motor 130 on the air duct cylinder 120, in this embodiment, only at the lower end of the air duct cylinder 120 are there legs 121 for supporting it, so that the lower end of the air duct cylinder 120 is suspended, facilitating the installation of the motor 130. Meanwhile, outside air can enter through the lower end opening of the air duct cylinder 120.

[0036] In this embodiment, a detachable cylinder cover 140 is provided at the upper end opening of the treatment cylinder 100. The cylinder cover 140 is provided with ventilation holes to ensure that the air blown into the treatment cylinder 100 can escape, avoiding excessive pressure inside the treatment cylinder 100 and affecting the actual use of the device.

[0037] In this embodiment, a fan blade 241 is provided on the rotating shaft 240. The rotating shaft 240 drives the fan blade 241 to rotate to blow the air outside the air duct cylinder 120 into the air duct cylinder 120.

[0038] In this embodiment, through the arrangement of the fan blade 241, during actual use, the rotation of the rotating shaft 240 drives the fan blade 241 to rotate, sucking the air outside the air duct cylinder 120 into the air duct cylinder 120, realizing the air flow inside the air duct cylinder 120, dissipating heat from the heat dissipation fins 231, and cooling the coolant in the cooling loop pipe 110.

[0039] In this embodiment, the knocking member includes a knocking plate 270 provided below the filter plate 210. The knocking plate 270 is provided with knocking columns 401 for knocking the filter plate 210, and the knocking plate 270 is provided with a lifting rod 271 extending through the treatment cylinder 100. A second driving member is provided at the upper end of the rotating shaft 240. The rotation of the rotating shaft 240 is used to drive the second driving member to drive the lifting rod 271 to lift and lower.

[0040] In this embodiment, the second driving member drives the lifting rod 271 to lift and lower, thereby driving the knocking plate 270 so that the knocking columns 401 impact the filter plate 210, causing the filter residue to vibrate and improving the filtering effect of the filter plate 210 on the mixed liquid.

[0041] In this embodiment, the second driving member includes a spring 610 sleeved on the lifting rod 271. The spring 610 is used to push the knocking column 401 to abut against the lower side of the filter plate 210. A lifting column 620 is provided at the lower end of the lifting rod 271. An annular groove 621 is provided along the circumferential direction of the outer side wall of the lifting column 620. Opposite convex blocks 622 are provided in the annular groove 621. A guiding surface 623 is provided on the outer side wall of the convex block 622. Opposite guiding rods 630 extending into the annular groove 621 are provided at the upper end of the rotating shaft 240. The rotation of the rotating shaft 240 is used to drive the guiding rods 630 to slide along the guiding surface 623 to drive the lifting rod 271 to descend.

[0042] In this embodiment, in combinationFigure 6 As shown in the figure, the upper end of the bump 622 is fixedly connected to the top wall of the annular groove 621. One side surface of the bump 622 forms a guiding surface 623, and the other side surface forms a vertical surface. In the initial state, the upper end of the spring 610 abuts against the knocking plate 270, and the lower end abuts against the bottom wall of the treatment cylinder 100, so that the knocking column 401 abuts against the filter plate 210. At this time, the guiding rod 630 abuts against the top wall of the annular groove 621. At this time, when the rotating shaft 240 rotates, it can drive the guiding rod 630 to rotate in the annular groove 621. When the guiding rod 630 slides along the guiding surface 623 to the bottom wall of the bump 622, at this time, the lifting rod 271 descends. When the guiding rod 630 slides to the vertical surface, under the action of the spring 610, the lifting rod 271 moves upward to make the knocking plate 270 move upward, so that the knocking column 401 impacts the filter plate 210, causing the filter plate 210 to vibrate. At this time, when the rotating shaft 240 continues to rotate, it can drive the filter plate 210 to vibrate continuously to improve the filtering effect of the filter plate 210.

[0043] Specifically, in order to limit the lifting rod 271 and enable the rotation of the rotating shaft 240 to drive the lifting and lowering of the lifting rod 271, a through hole for the lifting rod 271 to penetrate is provided on the bottom wall of the treatment cylinder 100. Among them, a slider is provided on the side wall of the through hole, and a chute is provided along the axial direction on the outer side wall of the lifting rod 271. By using the slider to slide in the chute, the lifting rod 271 is restricted so that it cannot rotate circumferentially.

[0044] In this embodiment, a plurality of air guide pipes 122 are circumferentially distributed at the upper end of the air duct cylinder 120, and the air guide pipes 122 extend into the treatment cylinder 100 for blowing air to the filter plate 210.

[0045] In this embodiment, through the arrangement of the air guide pipes 122, during actual use, the rotation of the fan blade 241 can make the flowing air in the air duct cylinder 120 blow the filter residue on the filter plate 210 through the air guide pipes 122, so that the filter residue on the filter plate 210 can be turned over, thereby further improving the filtering effect of the filter plate 210.

[0046] This embodiment also provides a cooling and filtering method for rhodium catalyst, which uses the above-mentioned cooling and filtering device for rhodium catalyst, and specifically includes the following steps: S1. Through the opening and closing of the cylinder cover 140, the raw material of the mixed liquid to be treated is poured onto the filter plate 210 through the upper opening of the treatment cylinder 100, so that the filter plate 210 filters the raw material of the mixed liquid. S2. In step S1, start the motor 130 to drive the rotation of the rotating shaft 240, which can then drive the piston ring 220 to move up and down, so as to realize the circulating flow of the coolant in the cooling pipe 211 and the cooling ring pipe 110, and cool down the mixed liquid raw material on the filter plate 210. At the same time, the rotation of the rotating shaft 240 drives the rotation of the fan blade 241 to make the air flow in the air duct cylinder 120, so that the heat in the coolant in the cooling ring pipe 110 is dissipated through the heat dissipation fins 231, so as to cool down the coolant, thus facilitating the coolant to circulate and cool down the mixed liquid raw material on the filter plate 210; S3. In step S2, the rotation of the rotating shaft 240 drives the guide rod 630 to rotate in the annular groove 621 and slide along the guide surface 623, so as to realize the lifting of the lifting rod 271, and then drive the knocking plate 270 to move up and down so that the knocking column 401 impacts the filter plate 210 to make it vibrate; at the same time, the air duct 122 can introduce the air sucked by the fan blade 241 into the air duct cylinder 120 into the treatment cylinder 100 to blow the filter residue on the filter plate 210, thereby further improving the filtering effect of the filter plate 210 on the mixed liquid raw material.

[0047] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.

10. A cooling and filtration method for a rhodium catalyst, characterized in that: It adopts a rhodium catalyst cooling and filtering device described in any one of claims 1-9, and specifically includes the following steps: S1. Pour the mixed liquid raw material to be treated into the filter plate (210) through the upper end opening of the treatment cylinder (100) so that the filter plate (210) filters the mixed liquid raw material. S2. In step S1, start the motor (130) to drive the rotating shaft (240) to rotate, and then drive the piston ring (220) to lift and lower through the first driving member. At the same time, drive the fan blade (241) to rotate to make the air flow in the air duct cylinder (120), so that the coolant in the cooling ring pipe (110) is dissipated, and cooperate with the function of the air inlet member to cool the mixed liquid raw material on the filter plate (210). S3. In step S2, the rotation of the rotating shaft (240) drives the guiding rod (630) to rotate, and then drives the filter plate (210) to vibrate through the second driving member. At the same time, the air guide pipe (122) can introduce the air sucked by the fan blade (241) into the air duct cylinder (120) into the treatment cylinder (100) to blow the filter residue on the filter plate (210), thereby further improving the filtering effect of the filter plate (210) on the mixed liquid raw material.
