Detailed Implementation

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

[0026] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] Example 1: In the prior art, there is an uneven impregnation phenomenon in the impregnation of particulate catalysts. The present invention addresses this by setting up the structure shown in the figure, specifically including a body 100. A heating component and a rotating component are arranged inside the body 100. The heating component includes a heating element 101 and a hot air duct 102 connected to the air outlet of the heating element 101. The rotating component includes a rotating motor. The output shaft of the rotating motor is rotatably connected to an impregnation pot 110. The impregnation pot 110 is located on the upper side of the body 100. The free end of the hot air duct 102 extends into the impregnation pot 110.

[0028] A spraying assembly 200 for spraying the impregnation solution is also provided. The spraying assembly 200 includes a mounting ring 210 and a rotating disk 220. The mounting ring 210 is disposed above the opening of the impregnation pot 110. One end face of the mounting ring 210 is provided with a plurality of nozzles 211, which face the impregnation pot 110. The other end face of the mounting ring 210 is provided with a mounting post 212. The free end of the mounting post 212 is fixedly connected to the rotating disk 220. The rotating disk 220 is driven by a drive motor 213 so that the nozzles 211 can reciprocate in a semi-circular motion around the central axis of the mounting ring 210.

[0029] In one embodiment, the system includes a body 100, within which a heating assembly and a rotating assembly are installed. The heating assembly is primarily used to heat gas and mainly includes a heating element 101 and a hot air duct 102 connected to the heating element 101. The heating element 101 is a conventional prior art technology, and its function is to heat air. The heated gas is then transported through the hot air duct 102. The rotating assembly mainly includes a rotating motor and an impregnation pot 110. The impregnation pot 110 is located on the upper side of the body 100 and is shaped like a water chestnut or a sphere. The particulate catalyst to be impregnated is placed in the impregnation pot 110. The free end of the hot air duct 102 can extend into the impregnation pot 110 to provide heat during the impregnation process, facilitating uniform impregnation.

[0030] To achieve uniform impregnation with the impregnation solution, a spraying mechanism is also provided. This spraying mechanism is positioned above the opening of the impregnation pot 110. The spraying assembly 200 includes a mounting ring 210 and a rotating disk 220. Several nozzles 211 are mounted on the mounting ring 210, facing the impregnation pot 110 to ensure uniform spraying of the impregnation solution into the pot. To further ensure even spraying of the impregnation solution onto the particulate catalyst, a mounting post 212 is provided on the back of the mounting ring 210. The rotating disk 220 is connected to the mounting post 212, and a drive motor 213 drives the rotating disk 220 to rotate, thereby... The mounting ring 210 can rotate. The rotation of the mounting ring 210 and the nozzle 211 allows the impregnation liquid to be sprayed more evenly onto the particulate catalyst. Furthermore, in order to facilitate control of the rotation direction and frequency, the drive motor 213 is set to rotate forward and reverse, so that the nozzle 211 can rotate semi-circularly around the central axis of the mounting ring 210. The reciprocating rotation of the nozzle 211 allows the impregnation liquid to be sprayed evenly and linearly, thereby achieving a more uniform impregnation purpose. In addition, the nozzle 211 also needs to be connected to the delivery hose for conveying the impregnation liquid. By setting the semi-circular reciprocating rotation, pipe entanglement can also be avoided.

[0031] By setting an mounting ring 210 with several nozzles 211 above the opening of the impregnation pot 110, and fixing the mounting ring 210 to the rotating disk 220, the rotating disk 220 is rotated by the drive motor 213, which in turn drives the mounting ring 210 to rotate. The rotation is preferably a semi-circular reciprocating motion around the central axis of the mounting ring 210, so that the impregnation liquid sprayed from the nozzles 211 can be sprayed more evenly in the impregnation pot 110, so as to achieve the purpose of uniform impregnation of particulate catalyst. This structure is ingeniously designed, which can evenly spray the impregnation liquid, achieve uniform impregnation effect, and improve impregnation efficiency.

[0032] Example 2: In the above embodiment, the spraying component 200 is located at the mouth of the impregnation pot 110, making it inconvenient to add the granular catalyst. To facilitate material addition, a lifting component 300 is further provided. Specifically, the lifting component 300 includes a column 310, the spraying component 200 is located at the top of the column 310, a lifting plate 311 is located at the bottom of the column 310, a telescopic rod 312 is located at the bottom of the lifting plate 311, and an extension platform 103 extends outward from the machine body 100. A transmission component 400 connected to the telescopic rod 312 is provided on the extension platform 103 so that the telescopic rod 312 can extend and retract to drive the lifting plate 311 to rise and fall.

[0033] An installation groove is provided in the extension platform 103, and the cylindrical body of the telescopic rod 312 is disposed in the installation groove. A gear ring 313 is provided on the top outer wall of the cylindrical body. The transmission assembly 400 includes a positioning plate 410, and a transmission motor 420 is disposed on the positioning plate 410. A transmission gear 430 is disposed on the output shaft of the transmission motor 420. The transmission gear 430 meshes with the gear ring 313 to drive the rod of the telescopic rod 312 to extend and retract within the cylindrical body.

[0034] In one embodiment, the lifting assembly 300 includes a column 310, on which the spraying assembly 200 is fixedly mounted. As shown in the figure, a lifting plate 311 is provided at the bottom of the column 310. The lifting plate 311 is raised and lowered by the extension and retraction of a telescopic rod 312. The extension and retraction of the telescopic rod 312 is achieved by a transmission assembly 400, which is an extension platform 103 extending outward from the body 100. The extension platform 103 also has a mounting groove. A cylinder is threaded onto the bottom of the telescopic rod 312, and the cylinder is movably mounted on... Inside the mounting slot, a gear ring 313 is fixedly fitted on the outer wall of the top of the cylinder. The transmission assembly 400 includes a positioning plate 410 fixedly mounted on the extension platform 103. A transmission motor 420 is mounted above the positioning plate 410. A transmission gear 430 is mounted on the output shaft of the transmission motor 420. The cylinder is rotated by the meshing of the transmission gear 430 and the gear ring 313, which in turn drives the telescopic rod 312 to extend and retract inside the cylinder, and then drives the lifting plate 311 to rise and fall. When it rises, the spraying assembly 200 moves away from the opening of the impregnation pot 110, thereby facilitating the feeding of materials.

[0035] Example 3: The lifting assembly 300 is further optimized in the above example by including a lifting rod 314. A sleeve 315 is slidably sleeved around the lifting rod 314. A compression spring is also provided between the bottom of the sleeve 315 and the lifting rod 314. A groove is also provided inside the extension platform 103, and the sleeve 315 is fixedly installed in the groove. The top of the lifting rod 314 is fixedly connected to the bottom of the lifting plate 311. The groove and the mounting groove are located around the transmission gear 430, and are symmetrically arranged adjacent to each other.

[0036] In one embodiment, a lifting rod 314 is also fixedly connected to the bottom of the lifting plate 311. A sleeve 315 is slidably sleeved on the outside of the lifting rod 314. A compression spring is also provided between the bottom of the lifting rod 314 and the bottom of the sleeve 315. The compression spring mainly plays a buffering role. The difference between the lifting rod 314 and the telescopic rod 312 is that the lifting rod 314 and the sleeve 315 are not threaded together. The sleeve 315 is fixedly installed in the sleeve groove. Through the cooperation of the lifting rod 314 and the telescopic rod 312, the lifting and lowering of the lifting plate 311 can be further coordinated.

[0037] The arrangement of the lifting rod 314 and the telescopic rod 312 is optimized. Specifically, there are two sleeve slots and two mounting slots, as shown in the figure, located around the transmission gear 430. The sleeve slots and the mounting slots are arranged adjacent to each other, with the two sleeve slots facing each other and the two mounting slots facing each other. This arrangement ensures that the lifting plate 311 can rise and fall normally while making the structure simpler.

[0038] Example 4: In the above example, the lifting component 300 is mounted on the extension platform 103. Since it does not have a fixed shielding structure, it is prone to misoperation or other safety hazards. Therefore, it is further designed as follows: a cover 104 is also provided above the extension platform 103. The transmission component 400, the cylinder and the sleeve 315 are all provided inside the cover 104. The top of the cover 104 is provided with a through hole, through which the telescopic rod 312 and the lifting rod 314 pass.

[0039] In one embodiment, by setting a cover 104, the transmission assembly 400, the cylinder, and the sleeve 315 are housed inside the cover 104, thereby enhancing structural integrity and reducing the error rate. To further improve the structure, four perforations are provided at the top of the cover 104, corresponding to the telescopic rod 312 and the lifting rod 314, to facilitate the extension of the telescopic rod 312 and the lifting rod 314.

[0040] Example 5: The impregnation equipment is further optimized in the above examples. Specifically, the free end of the hot air pipe 102 can pass through the mounting ring 210 and be placed inside the impregnation pot 110.

[0041] In one embodiment, by setting the free end of the hot air duct 102 to pass through the mounting ring 210, the hot gas from the hot air duct 102 can be placed inside the impregnation pot 110, thereby achieving uniform distribution of the hot gas. This, in turn, works with the uniformly distributed impregnation liquid to uniformly impregnate the particulate catalyst. The installation position of the hot air duct 102 does not affect the rotation of the semicircle of the mounting ring 210. As shown in the figure, the hot air duct 102 has a certain length above the opening of the impregnation pot 110, which is usually 25cm. Under the action of the lifting component 300, the spraying component 200 also rises along the hot air duct 102. In practice, the rising height of the spraying component 200 is usually about 10-20cm, which is convenient for feeding. Under this height premise, by setting the hot air duct 102 to pass through the mounting ring 210, a certain limiting effect can also be achieved to prevent the spraying component 200 from rising too high and affecting the overall operation.

[0042] The aforementioned mounting ring 210 can be a complete closed-loop structure, as shown in the figure, or it can be a mounting ring 210 with a notch. Preferably, it is a mounting ring 210 with a notch. When the hot air pipe 102 is inserted into the immersion pot 110, it is inside the mounting ring 210. During the lifting and lowering process, the hot air pipe 102 can be positioned relative to the notch. In this way, structural obstruction can be minimized during the lifting and lowering process, thereby achieving more free lifting and lowering.

[0043] Example 6: Further optimization of the impregnation equipment in the above examples: The mounting ring 210 has a mounting hole 214 on the side facing the impregnation pot 110. The nozzle 211 is fixedly installed in the mounting hole 214. The side of the mounting ring 210 also has a through hole communicating with the mounting hole 214. An infusion tubing is installed in the through hole, with one end connected to the nozzle 211 and the other end connected to a container holding the impregnation solution. An installation tube for fixing the infusion tubing is also provided outside the through hole.

[0044] In one embodiment, the structure of the mounting ring 210 is further optimized by providing mounting holes 214 on the mounting ring 210 for mounting nozzles 211, and by providing through holes on the side of the mounting ring 210 for mounting infusion tubing, so that the infusion tubing is connected to the nozzle 211, making it easier to feed the container containing the impregnation solution into the nozzle 211 for uniform spraying. The nozzle 211 adopts an existing design, such as a pressurized nozzle 211, which can spray a mist and disperse it evenly. In order to facilitate the installation of the infusion tubing and to prevent the infusion tubing from getting tangled during the semi-circular rotation of the mounting ring 210, a mounting tube is further provided. The mounting tube has a common tube structure. The fixed mounting tube extends outward to isolate the infusion tubing from each other at the joint, thereby achieving the purpose of avoiding tangling.

[0045] Example 7: Further optimization of the discharge method in the above examples. The existing discharge method has low efficiency. The bottom of the impregnation pot 110 is provided with a discharge port 111 and a discharge shell 112 corresponding to the discharge port 111. The discharge shell 112 is also provided with an opening and closing plate 113 for closing the discharge port 111 near the discharge port 111. The opening and closing plate 113 is provided at the bottom of the discharge shell 112. The two sides of the opening and closing plate 113 are hinged to the side walls of the discharge shell 112. A magnetic element is provided at the free end of the opening and closing plate 113. A magnetic block adapted to the magnetic element is provided at the top of the discharge shell 112.

[0046] In one embodiment: By providing a discharge port 111 and a discharge shell 112 corresponding to the discharge port 111 at the bottom of the impregnation pot 110, and providing an opening and closing plate 113 for closing the discharge port 111 at the bottom of the discharge shell 112, specifically, the two sides of the opening and closing plate 113 are hinged to the side wall of the discharge shell 112, a magnetic element is provided at the free end of the opening and closing plate 113, and a magnetic block adapted to the magnetic element is provided at the top of the discharge shell 112. When the impregnation pot 110 is in normal use, the opening and closing plate 113 closes the discharge port 111. After impregnation is completed, the magnetic element of the opening and closing plate 113 is moved away from the magnetic block, thereby opening the discharge port 111 and achieving the purpose of discharging the material.

[0047] The workflow of a volumetric impregnation device for granular catalysts is roughly as follows: The spraying component 200 is raised by the lifting component 300 to a height of approximately 10 cm. After the component is raised, the granular catalyst material is added. Then, the lifting component 300 is driven to move the spraying component 200 directly to the opening of the impregnation pot 110. The heating component is then activated, allowing hot gas to be transported into the impregnation pot 110 through the hot air pipe 102. Under the action of the rotating component, the impregnation pot 110 is rotated, causing the granular catalyst to rotate within the pot. The mounting ring 210 above the opening of the impregnation pot 110 is driven by the drive motor 213, allowing the mounting ring 210 to rotate semi-circularly around its axis, thereby achieving uniform impregnation by ensuring that the impregnation liquid is evenly mixed with the granular catalyst.

[0048] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
