Description

Technical Field

[0001] This invention belongs to the field of catalyst production technology, specifically relating to a multifunctional catalyst impregnation device. Background Technology

[0002] Impregnation is the most common method for preparing solid catalysts in industry, involving the uniform loading of one or more active components onto a support. Typically, a porous support is brought into contact with a solution of metal salts, allowing the metal salt solution to be adsorbed or stored within the pores of the support. After impregnation, excess solution is removed, and the resulting sample is then dried, calcined, and activated to obtain the final catalyst. The main impregnation methods are supersaturated impregnation and equal-volume impregnation. Impregnation allows for uniform distribution of the metal components on the support, reduces the amount of active components used, and improves the utilization rate of the active components.

[0003] In industrial catalyst impregnation, a batch impregnation method is generally used. A certain volume or mass of catalyst is loaded into a catalyst basket and hoisted into the impregnation liquid storage tank. After impregnation, the catalyst basket is hoisted out and then subjected to subsequent processes such as drying and calcination. However, the current batch impregnation method has the following disadvantages: (1) The catalyst is placed in the catalyst basket during the entire impregnation process, and it is difficult for the active components to be impregnated evenly and quickly, so as not to achieve the effect of rapid and uniform dispersion; (2) The impregnation device in the existing technology has a single function, and drying is required after impregnation, which is cumbersome; (3) There will be a certain amount of precious metal components in the impregnation liquid. The amount used is small but the price is very expensive. How to recover and make full use of the remaining impregnation liquid is also a problem that must be considered in industrial production.

[0004] Therefore, this solution proposes a multifunctional catalyst impregnation device to address the problems of existing catalyst impregnation devices being unable to impregnate quickly and uniformly, and having limited functionality. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional catalyst impregnation device, which solves the technical problems of existing catalyst impregnation devices that cannot impregnate evenly and quickly, and have limited functionality. At the same time, it achieves the technical effect of drying and is also conducive to the recovery of precious metal components, thus having multiple technical effects.

[0006] A multifunctional catalyst impregnation device includes a positioning frame, a fixed cylinder with its opening facing upward and mounted on the positioning frame, the bottom end of the fixed cylinder being connected to a hot air assembly, a feed cylinder and a liquid inlet cylinder being connected to the side of the fixed cylinder, and a flared cylinder being coaxially mounted on the top end of the fixed cylinder.

[0007] The fixed cylinder is equipped with a material holding structure for taking out materials. The top of the material holding structure is connected to a lifting mechanism, and the lifting mechanism is connected to a top cover. A drying space for the catalyst is formed between the top cover and the flared cylinder. A cylindrical structure for sealing the drying space is provided between the top cover and the flared cylinder.

[0008] The hot air assembly includes a jet head, a hot air pipe connected to one end of the jet head, and a hot air blower connected to the other end of the hot air pipe, the hot air pipe passing through the side wall of the fixed cylinder;

[0009] The bottom end of the jet head is provided with a plurality of jet holes, which face the inner bottom surface of the fixed cylinder.

[0010] The top cover is connected to the suction structure; the suction structure includes a suction tube with one end passing through the top cover and a suction pump connected to the other end of the suction tube, and the suction pump is fixed to the upper surface of the top cover.

[0011] The suction tube extends into the cylindrical structure.

[0012] The material holding structure includes an upper fixed plate and a lower fixed plate arranged horizontally and parallel to each other, and several rotating plates arranged vertically between the upper fixed plate and the lower fixed plate;

[0013] The upper and lower end faces of the rotating plate are provided with fixed shafts, and the upper and lower ends of the fixed shafts are respectively rotatably mounted on the upper fixed plate and the lower fixed plate. The upper ends of several fixed shafts are simultaneously connected to the power structure, and the power structure is mounted on the upper fixed plate.

[0014] The upper fixed plate is connected to the lifting mechanism, and its upper and lower bottom surfaces are provided with through holes.

[0015] The power structure includes a gear five disposed on the upper end of the fixed shaft, a toothed belt that meshes with several gear five simultaneously, and a motor two that is connected to one of the fixed shafts. The motor two is disposed on the upper fixed plate.

[0016] The lifting mechanism includes a toothed rod with its bottom end perpendicularly connected to the upper surface of the upper fixed plate, a second gear and a fourth gear respectively meshing on both sides of the toothed rod, a first gear coaxially connected to the second gear, and a third gear coaxially connected to the fourth gear. The first gear and the third gear are meshed together. The first gear, the second gear, the third gear and the fourth gear are all rotatably mounted on a fixed seat, which is located on the upper surface of the top cover.

[0017] It also includes a motor that is coaxially connected to either gear two or gear four.

[0018] The cylindrical structure includes a first semicircular plate and a second semicircular plate. Both ends of the first semicircular plate are provided with insert strips, and both ends of the second semicircular plate are provided with opening slots. The insert strips can be detachably inserted into the opening slots to form a cylindrical shape.

[0019] A limiting structure is provided on the outer side of the cylindrical structure.

[0020] The limiting structure includes positioning rods respectively disposed on both sides of the top cover, with one end of the positioning rod rotatably disposed on the side of the top cover;

[0021] It also includes fastening bolts respectively disposed on both sides of the cylindrical structure, with one end of each fastening bolt passing through both sides of the bracket and abutting against the outer sides of the first and second semicircular plates respectively.

[0022] The through hole is connected to the bottom end of the suction tube.

[0023] This invention achieves the following significant effects:

[0024] (1) This solution includes a hot air assembly, which can simultaneously achieve the following technical effects:

[0025] First, it is equipped with a jet head, and below the jet head is a jet hole. The jet hole continuously emits hot gas and moves upward, continuously bubbling, which makes the catalyst tumble in the impregnation liquid, so that the upper and lower layers of the catalyst are in full contact with the impregnation liquid.

[0026] Secondly, the hot air generated by the hot air blower helps to raise the temperature of the impregnation liquid, strengthens molecular motion, and increases the diffusion effect of active components.

[0027] Third, after the entire impregnation process is completed, a small amount of impregnation liquid is located at the bottom of the fixed cylinder. Under the continuous baking of high temperature hot air, the liquid evaporates and the precious metal components precipitate, which helps the subsequent collection of precious metal components.

[0028] Fourth, the generation of hot gas helps the subsequent drying process of the catalyst and accelerates the drying rate.

[0029] (2) This solution includes a material holding structure, which can simultaneously achieve the following technical effects:

[0030] Firstly, after the entire impregnation process is completed, the catalyst can be sealed inside the material holding structure, and the material holding structure can be lifted up, which facilitates the subsequent drying and collection of the catalyst.

[0031] Secondly, under the action of motor two, the rotating plate can swing in the impregnation liquid, which is conducive to the disturbance of the impregnation liquid, realizes the stirring of the catalyst, and helps the impregnation liquid and the catalyst to have full contact.

[0032] Third, after the impregnation is completed, the material holding structure is raised to a certain height for drying. Since the material holding structure is basically closed, the impregnation liquid will drip down from the material holding structure and fall into the inside of the fixed cylinder. Since the impregnation liquid contains precious metal components, the precious metal components are preserved and saved.

[0033] (3) It is equipped with a suction structure, which achieves the following technical effects:

[0034] First, it creates negative pressure inside the fixed cylinder, which makes the hot gas bubble faster, increases the speed of catalyst tumbling and movement, and enhances the contact strength between the impregnation liquid and the catalyst.

[0035] Secondly, the negative pressure generated during the drying process helps the liquid on the catalyst surface evaporate and promotes its rapid drying.

[0036] (4) It has a cylindrical structure, which has the following technical advantages:

[0037] First, it is easy to install and disassemble, and can be installed or disassembled according to the actual situation;

[0038] Secondly, it provides an enclosed space, which is helpful for the impregnation and drying processes;

[0039] Third, it facilitates the removal of the catalyst after drying, making it convenient, quick, and beneficial for operation. Attached Figure Description

[0049] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0050] A multifunctional catalyst impregnation device includes a positioning frame 7, a fixed cylinder 8 with its opening facing upward and set on the positioning frame 7, the bottom end of the fixed cylinder 8 being connected to a hot air assembly, the side of the fixed cylinder 8 being connected to a feed cylinder 11 and a liquid inlet cylinder 12, and the top end of the fixed cylinder 8 being coaxially provided with a flared cylinder 6.

[0051] A material holding structure for taking out material is movably installed inside the fixed cylinder 8. The top of the material holding structure is connected to the lifting mechanism 15. The lifting mechanism 15 is connected to the top cover 1. A drying space for the catalyst is formed between the top cover 1 and the flared cylinder 6. A cylindrical structure for sealing the drying space is provided between the top cover 1 and the flared cylinder 6.

[0052] The hot air assembly includes a jet head 101, a hot air pipe 10 connected to one end of the jet head 101, and a hot air blower 9 connected to the other end of the hot air pipe 10. The hot air pipe 10 passes through the side wall of the fixed cylinder 8.

[0053] The bottom end of the jet head 101 is provided with a number of jet holes 102, which face the inner bottom surface of the fixed cylinder 8.

[0054] The top cover 1 is connected to the suction structure; the suction structure includes a suction pipe 141 with one end passing through the top cover 1 and a suction pump 14 connected to the other end of the suction pipe 141. The suction pump 14 is fixed on the upper surface of the top cover 1.

[0055] The suction tube 141 extends into the cylindrical structure.

[0056] The material holding structure includes an upper fixed plate 16 and a lower fixed plate 21 that are horizontally arranged and parallel to each other, and several rotating plates 20 that are vertically arranged between the upper fixed plate 16 and the lower fixed plate 21.

[0057] Fixed shafts 201 are provided on the upper and lower end faces of the rotating plate 20. The upper and lower ends of the fixed shafts 201 are respectively rotatably mounted on the upper fixed plate 16 and the lower fixed plate 21. The upper ends of several fixed shafts 201 are simultaneously connected to the power structure, which is mounted on the upper fixed plate 16.

[0058] The upper fixed plate 16 is connected to the lifting mechanism 15, and its upper and lower bottom surfaces are provided with through holes.

[0059] More preferably, in order to prevent the rotating plate 20 from interfering with the inner wall of the fixed cylinder 8 when it rotates, the fixed shaft 201 is set at the end of the rotating plate 20, which indirectly increases the volume of the material holding structure.

[0060] The power structure includes a gear 17 mounted on the upper end of a fixed shaft 201, a toothed belt 18 that meshes with several gears 17, and a motor 19 connected to one of the fixed shafts 201. The motor 19 is mounted on the upper fixed plate 16.

[0061] The rotation of any one fixed shaft 201 will drive the other fixed shafts 201 to rotate via the toothed belt 18. This is a routine operation for those skilled in the art and will not be described in detail here.

[0062] The lifting mechanism 15 includes a toothed rod 153 whose bottom end is vertically connected to the upper end face of the upper fixed plate 16, a second gear 152 and a fourth gear 155 respectively meshing on both sides of the toothed rod 153, a first gear 151 coaxially connected to the second gear 152, and a third gear 154 coaxially connected to the fourth gear 155. The first gear 151 and the third gear 154 are meshed together. The first gear 151, the second gear 152, the third gear 154 and the fourth gear 155 are all rotatably mounted on the fixed seat, which is located on the upper end face of the top cover 1.

[0063] It also includes a motor 156 that is coaxially connected to gear three or gear four 155.

[0064] To simplify the design, rack 153, gear 152 and gear 155 are shown in schematic diagrams. During operation, motor 156 drives gear 151 and gear 354 to rotate, which in turn drives gear 2152 and gear 4155 to rotate, thereby lifting rack 153. Rack 153 then lifts the holding structure.

[0065] The cylindrical structure includes a first semicircular plate 4 and a second semicircular plate 13. Both ends of the first semicircular plate 4 are provided with an insert strip 41, and both ends of the second semicircular plate 13 are provided with an opening groove 131. The insert strip 41 can be detachably inserted into the opening groove 131 to form a cylindrical shape.

[0066] A limit structure is provided on the outside of the cylindrical structure.

[0067] The limiting structure includes positioning rods 1-1 respectively disposed on both sides of the top cover 1, with one end of the positioning rods 1-1 rotatably disposed on the side of the top cover 1;

[0068] It also includes fastening bolts 3 respectively set on both sides of the cylindrical structure. One end of the two fastening bolts 3 passes through both sides of the bracket 2 and abuts against the outer side of the semicircular plate 1 4 and the semicircular plate 2 13 respectively.

[0069] The through hole is connected to the bottom end of the suction tube 141.

[0070] The specific working process of this invention is as follows:

[0071] First, using the lifting mechanism 15, the material holding structure is lowered until it stops moving near the jet head 101. Then, using the motor 19, the rotating plate 20 is rotated at a certain angle to open the material holding structure. A certain amount of impregnation liquid is poured into the liquid inlet cylinder 12, and then the catalyst is introduced into the feed cylinder 11. At this time, the catalyst enters the impregnation liquid.

[0072] A hot air assembly is provided at the bottom of the fixed cylinder 8. Under the action of the jet head 101, a jet hole 102 is provided below the jet head 101. The jet hole 102 continuously emits hot gas and moves upward, continuously bubbling, causing the catalyst to continuously roll in the impregnation liquid, so that the upper and lower layers of the catalyst are in full contact with the impregnation liquid.

[0073] The hot air generated by the hot air blower 9 helps to raise the temperature of the impregnation liquid, strengthens molecular motion, and increases the diffusion effect of active components;

[0074] During the impregnation process, motor 219 can be used to make the rotating plate 20 swing slowly, which is beneficial to agitate the impregnation liquid and increase the stirring effect. After the entire impregnation process is completed, motor 219 is started so that several rotating plates 20 are in contact end to end to form a closed shape. Lifting mechanism 15 is used to raise the holding structure to the cylindrical structure position and stop it to carry out the drying process.

[0075] At this time, due to the gap between adjacent rotating plates 20 and between rotating plates 20 and lower fixed plate 21, the impregnation liquid in the holding structure will flow out continuously and fall into the fixed cylinder 8. Since the impregnation liquid contains precious metal components, the precious metal components are preserved and saved. The generation of hot gas helps the catalyst drying process and accelerates the drying rate.

[0076] It should be noted that the lower fixing plate 21 is provided with a leakage hole 211. On the one hand, it helps the air bubbles to emerge from the leakage hole 211, and on the other hand, it allows the impregnation liquid to flow out from the leakage hole 211.

[0077] At this time, the suction pump 14 is always on, drawing out the hot gas from the container structure. The flexible suction pipe 141 can be bent to be adjusted according to the actual situation. The suction pump 14 not only creates negative pressure in the fixed cylinder 8, making the hot gas bubble faster, increasing the speed of catalyst tumbling and movement, and enhancing the contact strength between the impregnation liquid and the catalyst, but also when entering the drying process, the generation of negative pressure helps the evaporation of liquid on the catalyst surface and promotes its rapid drying.

[0078] One of the superior effects of this scheme is that while the drying process is in progress, the catalyst can continue to be introduced into the feed cylinder 11, so that the catalyst can be impregnated in the impregnation liquid. In this way, the impregnation process can continue while drying, which greatly improves the impregnation efficiency of the catalyst.

[0079] When the entire impregnation process is completed and the precious metal in the fixed cylinder 8 needs to be collected, a small amount of impregnation liquid is located at the bottom of the fixed cylinder 8. Under the continuous baking of high temperature hot air, the liquid evaporates and the precious metal components precipitate, which greatly helps the subsequent collection of precious metal components.

[0080] Regarding the collection of precious metal components, manual collection is possible. One innovation of this solution is that the drying process does not involve leaving the impregnation device, thus avoiding waste of precious metal components.

[0081] After the drying process is completed, rotate the positioning rod 1-1 and the fastening bolt 3, and use the handle 5 to release the cylindrical structure from the limit, that is, separate the semi-circular plate 1-4 and the semi-circular plate 2-13 to remove them. Since the insert strip 41 is embedded in the opening groove 131 by interference fit, the two are easy to join and separate. At this time, the cylindrical structure can be disassembled. Since the top cover 1 is connected to the bracket 2, the top cover 1 will not fall off. Use the motor 2-19 to open the rotating plate 20. At this time, people can collect the catalyst inside the structure.

[0082] The technical features of this invention not described can be implemented by or using existing technology, and will not be repeated here. Of course, the above description is not a limitation of this invention, and this invention is not limited to the examples above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of this invention should also be within the protection scope of this invention.
