Description

Technical Field

[0001] This utility model relates to the field of catalyst production technology, and in particular to an impregnation apparatus for catalyst production. Background Technology

[0002] The process involves immersing a solid powder or a pre-formed solid of a specific shape and size in a solution of a soluble compound containing an active ingredient. After a certain period of contact, the residual liquid is separated. In this way, the active ingredient adheres to the solid in the form of ions or compounds. This method is called impregnation.

[0003] like Figure 3 As shown, this is the impregnation device used in the production and processing of the previous generation of catalysts. Its main function is to accelerate the adhesion of the impregnation liquid to the voids and surface of the solid catalyst. However, this type of impregnation device has the following shortcomings in actual use: In the actual impregnation process, although vacuuming or pressurizing can accelerate the mixing of the impregnation liquid and the catalyst, the solid catalyst is concentrated in the impregnation basket, while the impregnation liquid is mainly at the bottom of the tank. The solid-liquid fusion effect between the two is generally poor, which directly affects the efficiency of the actual impregnation process of the catalyst and the finished product effect.

[0004] Therefore, it is particularly important to design and manufacture an impregnation device that can improve the fusion effect between the impregnation liquid and the catalyst, enhance the impregnation process efficiency and the finished product quality, and apply it in the production and processing of catalysts. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the previous generation of catalyst production impregnation devices, the impregnation liquid and the catalyst were difficult to fully integrate during the actual impregnation process, resulting in poor impregnation efficiency and poor finished product quality. Therefore, this invention proposes an impregnation device for catalyst production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An impregnation apparatus for catalyst production includes a tank, an inlet pipe connected to the top left end of the tank, a drain valve connected to the bottom end of the tank, a tank cover rotatably mounted on the top end of the tank, a gas valve connected to the top end of the tank cover, multiple support blocks fixed in a ring array on the bottom inner side of the tank, an impregnation basket movably mounted between the multiple support blocks, and handles symmetrically fixed on both sides of the top end of the impregnation basket. A cradle mechanism is provided between the bottom end of the tank and the bottom end of the impregnation basket to drive the impregnation basket to reciprocate and improve the solid-liquid mixing impregnation effect.

[0008] As a further description of the above technical solution:

[0009] The cradle mechanism includes a drive motor installed at the lower end of the tank, a lower rotating block installed at the upper end of the drive motor, an outer protrusion integrally fixed at the upper end of the lower rotating block, an upper fixed block fixed at the lower end of the immersion basket and located directly above the lower rotating block, an inner groove opened at the lower end of the upper fixed block and corresponding to the outer protrusion, and a guide part provided between the immersion basket and the support block.

[0010] As a further description of the above technical solution:

[0011] The guide portion includes guide blocks that are fixed in a ring array outside the impregnation basket and extend outward through the support block, and guide grooves that are opened inside the support block and correspond to the guide blocks.

[0012] As a further description of the above technical solution:

[0013] A circulation section is provided between the inside and outside of the tank for circulating the impregnation liquid at the bottom of the tank into the impregnation basket.

[0014] As a further description of the above technical solution:

[0015] The circulation unit includes a liquid distribution ring installed in the middle of the inner side of the tank, a liquid guide pipe connecting the lower end of the tank and the liquid distribution ring, and a water pump installed outside the tank and connected to the liquid guide pipe.

[0016] As a further description of the above technical solution:

[0017] The liquid distribution ring is hollow inside, with its inner side inclined downwards, and multiple drainage holes arranged in a ring array at the bottom of its inner side.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] In this invention, the original impregnation device has been scientifically and rationally improved. A drive motor, a lower rotating block, an outer protrusion, an upper fixed block, and an inner groove are set between the tank and the impregnation basket. At the same time, a liquid equalization ring, a liquid guide pipe, and a water pump are set between the inside and outside of the tank. When the drive motor is working, it can drive the lower rotating block to rotate. The outer protrusion on the lower rotating block can slide back and forth into the inner groove on the upper fixed block, which can make the impregnation basket move up and down as a whole. At the same time, the water pump can draw the impregnation liquid at the bottom of the tank into the liquid equalization ring through the liquid guide pipe, and enter the impregnation basket from multiple directions through multiple drainage holes. This structure can make the impregnation liquid in the tank and the catalyst in the impregnation basket fully solid-liquid fused, reduce the problem of uneven mixing of catalyst and impregnation liquid, and thus improve the efficiency of catalyst impregnation processing and the finished product effect.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 This utility model provides a technical solution: an impregnation device for catalyst production, including a tank 1, an inlet pipe 101 connected to the top left end of the tank 1, a drain valve 102 connected to the bottom end of the tank 1, a tank cover 103 rotatably installed at the top end of the tank 1, an air valve 104 connected to the top end of the tank cover 103, multiple support blocks 3 fixed in a ring array at the bottom inside the tank 1, an impregnation basket 2 movably installed between the multiple support blocks 3, and handles 201 symmetrically fixed on both sides of the top end of the impregnation basket 2. A cradle mechanism is provided between the bottom end of the tank 1 and the bottom end of the impregnation basket 2 to drive the impregnation basket 2 to reciprocate and improve the solid-liquid mixing impregnation effect.

[0027] Specifically, such as Figure 1 and Figure 2As shown, the cradle mechanism includes a drive motor 4 mounted on the lower end of the tank body 1, a lower rotating block 401 mounted on the upper end of the drive motor 4, an outer protrusion 402 integrally fixed to the upper end of the lower rotating block 401, an upper fixed block 202 fixed to the lower end of the immersion basket 2 and located directly above the lower rotating block 401, an inner groove 203 formed at the lower end of the upper fixed block 202 and corresponding to the outer protrusion 402, and a guide portion provided between the immersion basket 2 and the support block 3. The outer protrusion 402 on the lower rotating block 401 rotates and slides into the upper fixed block 202. When the inner groove 203 is in place, the upper end face of the lower rotating block 401 can fit against the lower end face of the upper fixed block 202. At this time, the immersion basket 2 is in the lowest position of the reciprocating lifting motion. When the outer protrusion 402 on the lower rotating block 401 rotates and slides out of the inner groove 203 on the upper fixed block 202, the upper end face of the lower rotating block 401 can move and separate from the lower end face of the upper fixed block 202. At this time, the immersion basket 2 is in the highest position of the reciprocating lifting motion, so that the immersion basket 2 can reciprocate lifting motion under the rotation of the drive motor 4.

[0028] The guide section includes guide blocks 204 fixed in a ring array on the outside of the impregnation basket 2 and extending outward through the support block 3, and guide grooves 301 opened on the inside of the support block 3 and corresponding to the guide blocks 204. The arrangement of the guide blocks 204 and guide grooves 301 can, on the one hand, prevent the impregnation basket 2 from deflecting under the action of the lower rotating block 401, thereby improving the stability of the impregnation basket 2 installed between multiple support blocks 3. On the other hand, it can enable the impregnation basket 2 to move stably up and down between multiple support blocks 3.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, a circulation section is provided between the inside and outside of the tank 1 for circulating the impregnation liquid at the bottom of the tank 1 into the impregnation basket 2. The circulation section includes a uniform liquid ring 5 installed in the middle of the inner side of the tank 1, a liquid guide pipe 6 connecting the lower end of the tank 1 and the uniform liquid ring 5, and a water pump 7 installed outside the tank 1 and connected to the liquid guide pipe 6. When the water pump 7 is working, it can continuously draw the impregnation liquid at the bottom of the tank 1 into the uniform liquid ring 5 through the liquid guide pipe 6, and then transport the impregnation liquid to the impregnation basket 2 from multiple directions, so that the impregnation liquid and the catalyst can be fully mixed.

[0030] The liquid distribution ring 5 is hollow inside, with its inner side inclined downwards. The bottom of the inner side of the liquid distribution ring 5 has multiple drainage holes 501 arranged in a ring array. This structure of the liquid distribution ring 5 allows the impregnation liquid entering the liquid distribution ring 5 to be evenly divided into multiple streams and uniformly transported obliquely downwards into the impregnation basket 2.

[0031] Working principle: In use, the impregnation device is installed at the impregnation station of the catalyst production line. Then, the impregnation liquid delivery pipeline is connected to the inlet pipe 101, the gas valve 104 is connected to the gas supply pipeline, and the drain valve 102 is connected to the impregnation liquid drain pipeline. Finally, the circuit of the impregnation device is connected to the control terminal of the catalyst production line, thus completing the installation operation of the impregnation device. In actual use, the solid catalyst to be impregnated is poured into the impregnation basket 2, then the tank cover 103 is opened, and the impregnation basket 2 is placed from top to bottom between the multiple support blocks 3 of the tank body 1. The tank body 1 can then be closed. By controlling the opening and closing of the gas valve 104, the impregnation process of the tank body 1 can be performed. When vacuuming or pressurizing is performed, and the drive motor 4 is working, it can drive the lower rotating block 401 to rotate. The outer protrusion 402 on the lower rotating block 401 can slide back and forth into the inner groove 203 on the upper fixed block 202, thereby driving the impregnation basket 2 to move back and forth between multiple support blocks 3, accelerating the solid-liquid fusion of the impregnation liquid inside the tank 1 and the catalyst inside the impregnation basket 2. At the same time, when the water pump 7 is working, the impregnation liquid at the bottom of the tank 1 can be circulated into the uniform liquid ring 5 through the liquid guide pipe 6, and enter the impregnation basket 2 from multiple directions through multiple drain holes 501 on the uniform liquid ring 5, further accelerating the solid-liquid fusion of the impregnation liquid inside the tank 1 and the catalyst inside the impregnation basket 2.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
