[0001] This utility model relates to the technical field of impregnation and stirring devices, specifically to a catalyst impregnation and stirring device. Background Technology

[0002] The catalyst impregnation and stirring device is a key piece of equipment in the catalyst preparation process. Its main function is to ensure that the catalyst support is in full contact with the impregnation solution containing the active components through mechanical stirring, rotation, or fluid motion, thereby achieving uniform loading and distribution of the active components on the support. This device is the core equipment in the wet impregnation process, and its performance directly affects the activity, selectivity, and service life of the final catalyst.

[0003] Chinese utility model patent CN220496320U discloses a catalyst vacuum impregnation device, which includes "a support frame at the top of the base, a cover movably mounted on the support frame, a holding basket detachably connected to the bottom of the cover, a rotating shaft axially mounted at the center of the holding basket, several pressure plates evenly mounted circumferentially near the top of the rotating shaft, several stirring rods evenly mounted axially along the rotating shaft, the stirring rods being located below the pressure plates, and the stirring rods being spirally distributed and downwardly inclined"; however, the heating unit is not specified, which may lead to uneven adsorption rates of the active components to a certain extent, and the shear force cannot be adjusted, resulting in large material loss and stripping of the active components. Utility Model Content

[0004] The purpose of this invention is to provide a catalyst impregnation and stirring device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a catalyst impregnation and stirring device, comprising a base plate, a bracket and an intelligent control cabinet fixedly installed on the top of the base plate from left to right, a barrel assembly in the middle of the bracket, a heating ring and a microporous gas distributor sequentially arranged from the outside to the inside on the bottom of the inner wall of the barrel assembly, and fixing blocks on both the left and right sides of the outer wall of the barrel assembly, a telescopic rod fixedly installed on the top of each of the two fixing blocks, and a reinforcing block on the top of the telescopic rod, and a barrel lid assembly fixedly connected to the telescopic rod through the reinforcing block.

[0006] The bucket lid assembly includes a top cover, the top of which is bolted to a reinforcing block at the top of a telescopic rod, and an elastic sealing ring at the bottom of the top cover. A support plate is located at the center of the top of the top cover, with a liquid inlet on the left side of the support plate. A vacuum pump is located at the rear of the support plate, and a hydraulic cylinder is located at the front of the support plate. A first motor is bolted to the top of the support plate. The output end of the first motor passes through the support plate and the top cover from top to bottom, and has multiple stirring blades at its output port. A lead screw is movably sleeved on the output end of the first motor, and a first bevel gear is located at the top of the lead screw. The first bevel gear is connected to the output end of a second motor via a second bevel gear. The second motor is bolted to the inner wall of the support plate. A trapezoidal nut is movably sleeved on the outer wall of the lead screw, and a support frame is located on the outer wall of the trapezoidal nut. A container basket is fixedly installed on the support frame.

[0007] The beneficial effects of this utility model are as follows: This device can drive the lead screw to rotate via a second motor through gear transmission, thereby moving the catalyst in the basket up and down. The first motor drives the stirring blades to agitate the impregnation liquid, and the reduction motor rotates the entire barrel through gear meshing. The two can operate in opposite directions. The barrel wall is equipped with spiral blades to guide turbulence, and together with the heating ring and microporous gas distributor inside the barrel, it forms a high and low shear force adjustment, improves the uniformity of the adsorption rate of active components, reduces material loss, and prevents the peeling of active components.

[0008] To achieve rotation of the cylinder wall on the support, thus ensuring more uniform mixing of the impregnating liquid inside the cylinder wall:

[0009] Further configuration: the barrel assembly includes a geared motor, the geared motor is fixedly installed at the bottom of the horizontal plate of the bracket via a left side support plate, a drive gear is fixedly installed at the output end of the geared motor, the drive gear is connected to the barrel wall via multiple tooth blocks, a liquid outlet is provided at the bottom of the right outer wall of the barrel wall, fixing blocks are fixedly installed on both the left and right outer walls of the barrel wall, and a spiral blade is provided on the inner wall of the barrel wall.

[0010] By adopting the above technical solution, the geared motor rotates the entire cylinder wall through the meshing of the drive gear and multiple tooth blocks on the cylinder wall, driving the spiral blades inside the cylinder wall to guide turbulence. Combined with the stirring blades, the impregnating liquid inside the cylinder wall forms convection, making the stirring more uniform.

[0011] To allow the cylinder wall and top cover to be opened for easy replacement of materials such as catalysts, and to improve subsequent maintenance efficiency:

[0012] The hydraulic cylinder is further configured to be connected to the left hydraulic pump via a pipe, and the hydraulic pump is connected to the telescopic rod via telescopic hoses on both sides.

[0013] By adopting the above technical solution, the hydraulic pump guides the oil in the hydraulic cylinder through the telescopic hoses on both sides to two telescopic rods. The telescopic rods drive the top cover to be lifted off the cylinder wall as a whole, causing the basket containing the catalyst to be removed from the solution, which facilitates the replacement of materials such as catalysts and improves the efficiency of subsequent maintenance.

[0014] To maintain stability during cylinder wall rotation and improve the uniformity of catalyst impregnation and mixing:

[0015] The bracket is further configured such that the outer wall of the bracket has a groove whose inner wall and outer wall structure dimensions are consistent.

[0016] By adopting the above technical solution, a protruding ring is provided around the outer wall of the cylinder and is movably engaged in the bracket. Multiple balls are provided at the junction of the protruding ring and the inner groove of the bracket, which provides sufficient support for the cylinder wall and does not interfere with the rotation of the cylinder wall, thereby improving the uniformity of catalyst impregnation and stirring.

[0017] To ensure stable rotation of the lead screw on the top cover and improve impregnation uniformity:

[0018] The top cover is further configured such that the outer wall of the top cover has a groove whose inner wall size is consistent with the outer wall size of the lead screw, and the bottom end of the lead screw is provided with a limiting block.

[0019] By adopting the above technical solution, the second motor drives the second bevel gear to rotate, which in turn rotates the first bevel gear and the lead screw. The top of the lead screw is provided with a locking block that is locked in the groove of the top cover. The outer wall thread of the lead screw is set between the top cover and the limiting block. The trapezoidal nut moves up and down on the lead screw under the top cover, so that the lead screw rotates on the top cover and remains stable. The height adjustment of the immersion position can improve the immersion uniformity.

[0020] To achieve real-time adjustment of the negative pressure and temperature inside the cylinder wall, thereby improving the uniformity of impregnation:

[0021] The top cover is further configured such that, from left to right, a pressure sensor and a temperature sensor are arranged on the bottom left side.

[0022] By adopting the above technical solution, a pressure sensor and a temperature sensor are installed at the bottom of the top cover. The two sensors are connected to the intelligent control cabinet, heating ring, and vacuum pump through wiring. The intelligent control cabinet integrates PLC controller and other equipment. The two sensors feed back signals to the intelligent control cabinet. The intelligent control cabinet processes and analyzes the data and then adjusts the power of the heating ring and vacuum pump to maintain a suitable internal temperature and negative pressure, thereby improving the uniformity of impregnation.

The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.

[0038] Therefore, the "first motor 805", "second motor 8010", "gear motor 301" and other components involved in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application.

The improvement of this application should be the interaction between the various physical functional modules, that is, the improvement of the overall structure of the catalyst impregnation and stirring device of this application, so as to solve the corresponding technical problems to be solved by this application.

[0039] The working process of this catalyst impregnation and stirring device is as follows:

[0040] First, the staff uses the intelligent control cabinet to control the hydraulic pump via the circuit control to deliver oil from the hydraulic cylinder 804 to the two telescopic rods 7 through the telescopic hoses on both sides. The telescopic rods 7 rise, causing the top cover 801 to lift, placing the catalyst and other materials onto the trapezoidal nut 8011 and placing them in the basket. Then, following the same steps, the top cover 801 is returned to its original position. The top cover 801 is sealed to the cylinder wall 304 by the elastic sealing ring. The liquid inlet valve on the top cover 801 is opened, and the appropriate impregnation solution is introduced into the cylinder wall 304 through the liquid inlet. An elastic polymer coating is added to the inside of the cylinder wall 304. Then, the valve is closed, and the second motor 8010 is started. The second motor 8010 drives... The second bevel gear 809 rotates, which in turn drives the first bevel gear 808 and the lead screw 807 to rotate. The trapezoidal nut 8011 moves downward along the lead screw 807 and is immersed in the solution. Then, the first motor 805 is started. The first motor 805 drives multiple stirring blades 806 on the output end to rotate. The stirring blades 806 are covered with silicone. They cause the solution to collide with the cylinder wall 304 and the spiral blades, causing the internal air to be discharged upward. The intelligent control cabinet processes and analyzes the data from the air pressure sensor and temperature sensor inside the cylinder wall 304, and adjusts the power of the heating ring 4 and the vacuum pump 803. The vacuum pump 803 empties the internal air and maintains a moderate negative pressure. The heating ring 4 keeps the cylinder... The reaction temperature of the solution and catalyst inside the wall 304 is controlled by an intelligent control cabinet, which has been disclosed in a patent publication number (CN220496320U) as a catalyst vacuum impregnation device. The system starts the reduction motor 301, which drives the drive gear 302 to rotate at a constant speed, rotating multiple toothed blocks 303 on the cylinder wall 304. The drive gear 302 meshes with the multiple toothed blocks 303, causing the cylinder wall 304 to rotate on the support 2. The rotation direction of the cylinder wall 304 can be adjusted to ensure consistency with the output direction of the first motor 805. The microporous gas distributor 5 is activated at appropriate times. The microporous gas distributor 5 is connected to other external equipment via a bottom gas pipe, distributing nitrogen gas along the pipe from the micropores. Gas is ejected from the gas distributor 5 through the gas holes. The shear force is adjusted by various measures, such as adjusting the rotation speed of multiple stirring blades 806, the rotation speed of the cylinder wall 304, the nitrogen charging rate of the microporous gas distributor 5, the power of the heating ring 4 and the vacuum pump 803, and the vertical height of the trapezoidal nut 8011 on the screw 807, thereby improving the capillary permeability, eliminating the eggshell effect to a certain extent, preventing the active components from peeling off, and thus improving the uniformity of the adsorption rate of the active components. After impregnation, the second motor 8010 can be restarted to drive the trapezoidal nut 8011 and the holding basket to rise and drain the residual solution. Finally, the top cover 801 is opened to remove or replace the catalyst and other materials.
