Description

Technical Field

[0001] The invention relates to the technical field of catalyst production, and in particular to a preparation device for a Pt-M bimetallic catalyst. Background Art

[0002] Glycerol hydrogenolysis to propylene glycol is an important chemical reaction, which is mainly used to convert glycerol into 1,2-propylene glycol and 1,3-propylene glycol. These two propylene glycols are widely used in chemical, pharmaceutical and food fields. Traditional glycerol hydrogenolysis reactions usually use single metal catalysts such as Cu, Ni or Co, but these catalysts have problems such as low activity, poor selectivity and easy deactivation.

[0003] The Pt-M bimetallic catalytic system (M is another metal, such as Ru, Pd, Sn, etc.) can significantly improve the performance of glycerol hydrogenolysis reaction through synergistic effect. In the prior art, the preparation of Pt-M precursor is usually achieved by solution mixing and coprecipitation, and when the solutions are mixed in each process, a magnetic stirrer is generally required, and the stirrer is placed in the bottom center of the container, and the rotation of the stirrer located at the bottom of the container is driven by the non-contact magnetic force transmission method. This operation mode has the risk of collision between the stirrer and the inner wall of the container, and due to the limited specifications of the stirrer, there are the shortcomings of long stirring time and uneven mixing, which will directly cause the metal ratio in the final product to deviate from the design value, affecting the activity and stability of the catalyst. Summary of the invention

[0004] The purpose of the present invention is to provide a preparation device for a Pt-M bimetallic catalyst, which is not only provided with a unique structure of an eccentric tank relative to a cylindrical tank body, but also provided with a component consisting of a blanking tower and a feeding hopper; with the relative reverse rotation of the mixing disc and the connecting shaft, and a sliding seat that can automatically rise and fall, it can not only form a material shaking and dispersing action of the blanking tower, but also, after the blanking tower is extended into the eccentric tank and is in place, form an intermittent rotation action of the blanking tower in the opposite direction of the rotation of the eccentric tank, thereby efficiently mixing the two metal compounds with deionized water.

[0005] The object of the present invention is achieved through such a technical solution, a preparation device of a Pt-M bimetallic catalyst, comprising a main engine module, a mixing tank assembly, a feeding assembly, a mixing conduction assembly and an intermittent drive assembly, the main engine module comprising a mixing turntable and a connecting shaft, the mixing tank assembly comprising an eccentric tank, the feeding assembly comprising a hexagonal column, a drop tower, a feeding hopper and a partition fan plate, the mixing conduction assembly comprising a rotating bevel gear, and the intermittent drive assembly comprising a passive rubber wheel, an eccentric rubber wheel and a side connecting bevel gear;

[0006] The mixing disc and the connecting shaft are both screwed to the lower end of the main engine module and keep rotating in opposite directions. The eccentric tank is clamped and installed on the top of the mixing disc. The upper end of the main engine module is vertically slidably connected with a sliding seat that can automatically rise and fall. One end of the sliding seat is screwed to a hexagonal column fixed rotating seat. The hexagonal column is fixed in the hexagonal column fixed rotating seat. The top of the blanking tower is fixed to the bottom of the hexagonal column. The partitioning fan plate is arranged and fixed on the outside of the blanking tower. The inner bottom end of the feeding hopper is fixed to the outer top of the partitioning fan plate. A material dividing partition plate is arranged and fixed between the inner surface of the feeding hopper and the outer surface of the bottom end of the hexagonal column, and the material dividing partition plate on the same side is fixed to the partitioning fan plate.

[0007] The rotating bevel gear is plugged and fixed on the outside of the hexagonal column, a horizontal shaft is screwed on one side of the lower end of the sliding column, and the horizontal shaft is reversely connected to the rotating bevel gear, the passive rubber wheel is fixed on one end of the horizontal shaft, the top of the connecting shaft is plugged and fixed with the active bevel gear, the side connecting bevel gear is screwed on the bottom end of the sliding seat, and the eccentric end of the eccentric rubber wheel is coaxially fixed to the side connecting bevel gear.

[0008] The use process of the technical solution of the present invention is as follows:

[0009] The eccentric tank at the top of the mixing disc is used to hold a certain amount of deionized water for dilution. Different compound particles used in the bimetallic catalyst need to be dissolved in deionized water to prepare a precursor mixed solution and dilute it to a certain concentration.

[0010] After the eccentric tank is removed from the mixing disc, a certain amount of deionized water is added, and after the sliding seat moves upward to drive the drop tower to a position outside the eccentric tank, the two different compound particles can be evenly divided and then cross-fed into different cavities of the feeding hopper separated by the material dividing partition;

[0011] In this process, the lifting and moving sliding seat can drive the drop tower to form an up and down shaking effect, so that the compound particles can be evenly distributed to the outside of the steps at different heights of the drop tower, and in this process, a small amount of compound particles are allowed to fall downward into the deionized water in the eccentric tank;

[0012] The cam is then driven by the gear train, and the gear train is turned ...

[0013] After compound particles remain on the upper part of the outer step of the blanking tower, the blanking tower can be lifted by moving the sliding seat upward, so that the blanking tower is moved outside the eccentric tank, and the sliding seat is lifted and lowered to make the blanking tower shake up and down, so that the compound particles on the upper part of the outer step of the blanking tower flow to the lower part of the outer step of the blanking tower, and the blanking tower can be extended downward into the deionized water in the eccentric tank again, and the side connecting bevel gear is meshed with the active bevel gear. As the blanking tower maintains intermittent rotation in the opposite direction to the eccentric tank, the two different compound particles and deionized water can be quickly and evenly mixed to form a precursor mixed solution.

[0014] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0015] (1) The present invention is based on the relatively counter-rotating mixing disc and connecting shaft. It can not only form the rotation of the eccentric tank with a unique eccentric structure mounted on the top of the mixing disc, forming a shaking and mixing work for the liquid in the eccentric tank, but also cooperate with the downward movement of the sliding seat. When the side connecting bevel gear moves downward to a position meshing with the active bevel gear, the blanking tower extending into the eccentric tank can rotate in the opposite direction relative to the eccentric tank, so that the blanking tower used to carry the compound particles can maintain a rotation in the opposite direction to the shaking direction of the deionized water in the eccentric tank, thereby improving the mixing efficiency of the compound particles and the deionized water; and further, in order to further improve the mixing efficiency, the present invention also sets the eccentric rubber wheel to a state of eccentric connection with the side connecting bevel gear, which can form an intermittent contact and friction fit between the outer side of the eccentric rubber wheel and the passive rubber wheel, driving the intermittent rotation of the horizontal axis and the hexagonal prism and the blanking tower connected to the horizontal axis, so that the rotation and stop action of the blanking tower can form a turbulent work for the solution in the eccentric tank, so that the mixing of the compound particles and the deionized water in the eccentric tank is more uniform;

[0016] (2) In addition, the present invention also has partition panels evenly arranged and fixed on the outside of the material-bearing tower, and has material-dividing partition panels arranged and fixed between the inner surface of the feeding hopper and the outer surface of the bottom end of the hexagonal prism. The material-dividing partition panels can not only be used to divide the feeding hopper into a plurality of cavities, but also each group of cavities of the feeding hopper divided by the material-dividing partition panels can form an independent channel with the partition panels on the outside of the material-bearing tower on the same side, so as to form a cross-type feeding and discharging operation for the bimetallic compound particles, which is more conducive to the mixing of the bimetallic compound particles with deionized water. Moreover, the material-dividing structure composed of the material-bearing tower, the material-bearing hopper, the partition panels and the material-dividing partition panels, in conjunction with the moving action of the sliding seat, can not only realize the meshing of the side connecting bevel gear and the active bevel gear at the set position, but also realize the shaking operation of the material-bearing tower at the set position, so that the compound particles are dispersed from top to bottom on the outside of the step of the material-bearing tower, so that the compound particles are widely dispersed on the outside of the step of the material-bearing tower before they come into contact with the deionized water in the eccentric tank, thereby providing a prerequisite for the subsequent rapid mixing with deionized water.

[0033] like Figure 1-Figure 11 As shown, a preparation device for a Pt-M bimetallic catalyst, a mixing disc 106 and a connecting shaft 109 are both screwed to the lower end of a main engine module 1 and keep rotating in the opposite direction, an eccentric tank 201 is snap-fitted to the top of the mixing disc 106, and during the rotation of the mixing disc 106, the eccentric tank 201 will not be separated from the mixing disc 106, a sliding seat 302 that can be automatically lifted and lowered is vertically slidably connected to the upper end of the main engine module 1, one end of the sliding seat 302 is screwed to a hexagonal column fixed rotating seat 307, a hexagonal column 308 is fixedly connected to the hexagonal column fixed rotating seat 307, and a material dropping tower 303 is provided. The top of the hexagonal column 308 is fixedly connected to the bottom of the hexagonal column 308, the partitioning fan plate 314 is arranged and fixed on the outside of the material dropping tower 312, the inner bottom end of the feeding hopper 313 is fixedly connected to the outer top of the partitioning fan plate 314, and a material dividing partition plate 315 is arranged and fixed between the inner surface of the feeding hopper 313 and the outer surface of the bottom end of the hexagonal column 308, and the material dividing partition plate 315 on the same side is fixedly connected to the partitioning fan plate 314, so as to form a separate bulk material channel. The outside of the material dropping tower 312 is a conical step structure, and with the lifting and lowering action of the sliding seat 302, the material dropping tower 312 can move to the inside and outside of the eccentric tank 201;

[0034] The rotating bevel gear 401 is plugged and fixed on the outside of the hexagonal column 308, a horizontal shaft 406 is screwed on one side of the lower end of the sliding column 301, and the horizontal shaft 406 is connected to the rotating bevel gear 401 in reverse transmission, the passive rubber wheel 501 is fixed on one end of the horizontal shaft 406, the top of the connecting shaft 109 is plugged and fixed with the active bevel gear 506, the side connecting bevel gear 505 is screwed on the bottom end of the sliding seat 302, the eccentric end of the eccentric rubber wheel 504 is coaxially fixed with the side connecting bevel gear 505, and the eccentric rubber wheel 504 is located opposite to the passive rubber wheel 501, and when the eccentric rubber wheel 504 rotates to a certain position, the outside of the eccentric rubber wheel 504 contacts and cooperates with the passive rubber wheel 501, which can drive the intermittent rotation of the horizontal shaft 406;

[0035] Here’s how it works:

[0036] The eccentric tank 201 at the top of the mixing disc 106 is used to hold a certain amount of deionized water for dilution. Different compound particles used in the bimetallic catalyst need to be dissolved with deionized water to prepare a precursor mixed solution and dilute it to a certain concentration.

[0037] After the eccentric tank 201 is removed from the mixing disc 106, a certain amount of deionized water is added, and after the sliding seat 302 moves upward to drive the drop tower 312 to a position outside the eccentric tank 201, the two different compound particles can be evenly divided and then cross-added into different cavities of the feeding hopper 313 separated by the material dividing partition 315. The purpose of this operation is that, with the effect of gravity, the two different compound particles will cross-fall in advance into the channel formed by the outside of the step of the drop tower 312 and the dividing fan plate 314, which is convenient for subsequent mixing work;

[0038] In this process, the sliding seat 302 that can be lifted and moved can drive the drop tower 312 to form an up-and-down shaking effect, so that the compound particles can be evenly distributed to the outside of the steps at different heights of the drop tower 312, and in this process, a small amount of compound particles are allowed to fall downward into the deionized water in the eccentric tank 201;

[0039] As the sliding seat 302 moves downward to the side connecting bevel gear 505 and the active bevel gear 506 meshing in place, the blanking tower 312 also synchronously extends into the eccentric tank 201 and is in place, and the rotary drive mechanism connected to the connecting shaft 109 is started, which can drive the mixing disc 106 and the connecting shaft 109 to rotate in the opposite direction, and use the unique eccentric structure of the eccentric tank 201 to drive the deionized water in the eccentric tank 201 to form a shaking effect. On the other hand, the active bevel gear 506 and the side connecting bevel gear 505 can form a coordinated transmission, so that the side connecting bevel gear 505 coaxially drives the eccentric rubber wheel 5 04, due to the eccentric coaxial fixed connection between the eccentric rubber wheel 504 and the side connecting bevel gear 505, the outer surface of the eccentric rubber wheel 504 can form an intermittent contact and friction fit with the passive rubber wheel 501. When the eccentric rubber wheel 504 rotates to contact and fit with the passive rubber wheel 501, it can drive the rotation of the horizontal axis 406. The horizontal axis 406 drives the rotating bevel gear 401 and the horizontal axis 406 to maintain a relatively reverse rotation through the transmission mechanism, so that the blanking tower 312 can maintain a relatively reverse rotation with the eccentric tank 201 in a top view, and the blanking tower 312 can form an intermittent rotation state;

[0040] The purpose of setting the material drop tower 312 to intermittent rotation is that after the material drop tower 312 rotates in the opposite direction relative to the eccentric tank 201 for a period of time, the stopped state of the material drop tower 312 can form a turbulent effect on the solution in the agitated state, thereby improving the dissolution and mixing efficiency of different compound particles in deionized water;

[0041] Since the density of the metal compound is much greater than that of the deionized water, the metal compound in the deionized water will not be randomly dispersed due to the buoyancy effect as the drop tower 312 enters the eccentric tank 201. Instead, after the drop tower 312 is inserted into the eccentric tank 201 and is in place, the metal compound is evenly attached to the outside of the step of the drop tower 312.

[0042] After compound particles remain on the upper part of the outer step of the blanking tower 312, the blanking tower 312 can be lifted by the upward movement of the sliding seat 302, so that the blanking tower 312 moves outside the eccentric tank 201, and the blanking tower 312 is made to shake up and down by the lifting and lowering movement of the sliding seat 302, so that the compound particles on the upper part of the outer step of the blanking tower 312 flow to the lower part of the outer step of the blanking tower 312, and the blanking tower 312 can be extended downward into the deionized water in the eccentric tank 201 again, and the side connecting bevel gear 505 is meshed with the active bevel gear 506. As the blanking tower 312 maintains intermittent rotation in the opposite direction to the eccentric tank 201, the two different compound particles and the deionized water can be quickly and evenly mixed to form a precursor mixed solution;

[0043] To the prepared bimetallic precursor mixture solution, sodium hydroxide solution is slowly added under certain temperature conditions, and the pH value is adjusted to an appropriate value to allow the metal ions to fully precipitate. The precipitate can then be washed and dried. After drying, the metal precipitate is ground into powder and enters the calcination process. The calcined bimetallic powder is mixed with activated carbon in a certain proportion and then ground again to allow the bimetallic particles to be evenly dispersed on the surface of the activated carbon. After washing, filtering and drying again, it can support the final Pt-M bimetallic catalyst.

[0044] The specific structure of the host module 1 and the mixing tank assembly 2 is as follows: Figure 2 and Figure 3 As shown, a stand 102 is vertically fixed to one side of the outer top of the base 101, and a middle fixed seat 103 and a top fixed seat 104 are arranged and fixed on one side of the stand 102;

[0048] A feeding space 115 is provided in the main body of the middle fixed seat 103 at a position directly opposite to the mixing disc 106, for providing space for the movement of the feeding hopper 313 and its connected parts;

[0049] The main control center 114 starts the rotation drive motor 112, so that the driving gear 113 can drive the mixing disc 106 in the opposite direction of the connecting shaft 109 through the matching transmission formed by the connecting pinion 110 and the mixing gear 107;

[0050] The lower end of the eccentric tank 201 is a cylindrical structure, and the upper end is an eccentric cavity formed at the lower end. The plug-in column 202 is arranged and fixed on the outside of the cylindrical structure at the lower end of the eccentric tank 201. The top inner circle of the mixing disc 106 is provided with a plug-in chute 203. The anti-spin groove 204 is opened in the top inner circle of the mixing disc 106 with the mixing disc 106 as a path, and is connected to the plug-in chute 203.

[0051] Moreover, the opening direction of the anti-rotation groove 204 is consistent with the set rotation direction of the eccentric tank 201, that is, after the eccentric tank 201 is inserted into the plug-in slide groove 203 through the plug-in column 202 and rotated into the anti-rotation groove 204, when the mixing turntable 106 is rotating, the plug-in column 202 and the anti-rotation groove 204 will not fall out. When the mixing turntable 106 is stopped, the eccentric tank 201 can be processed and taken out by rotating it to the position where the plug-in column 202 and the plug-in slide groove 203 are opposite.

[0053] The main control center 114 starts the lead screw motor 305 to drive the rotation of the sliding lead screw 304, so that the sliding lead screw 304 and the lead screw slider 306 form a coordinated transmission, thereby driving the sliding seat 302 to move vertically guided by the sliding column 301;

[0054] A top rotating fixed seat 309 is fixedly installed at the top of the top fixed seat 104, and a top rotating slide 310 is rotatably connected inside the top rotating fixed seat 309. The upper end of the hexagonal column 308 is slidably connected to the top rotating slide 310, which can improve the stability of the movement and rotation of the hexagonal column 308;

[0055] The fan-shaped circular cover 311 is sleeved and fixed on the outside of the hexagonal column 308. The fan-shaped circular cover 311 is an inverted umbrella-shaped structure, and the outer diameter of the fan-shaped circular cover 311 is consistent with the inner diameter of the feeding space 115. The fan-shaped circular cover 311 is mainly used to form a protection for the space above the feeding hopper 313 during the preparation process to prevent oil impurities formed during mechanical coordination from falling into the feeding hopper 313.

[0056] The specific structures of the mixed conduction component 4 and the intermittent drive component 5 are as follows: Figure 7 , Figure 8 and Fig. 9 As shown, the conductive rotary seat 402 is fixedly connected to the bottom end of the sliding seat 302, the conductive rotary shaft 403 is rotatably connected to the conductive rotary seat 402, and the conductive bevel gear 404 is plugged and fixed to one end of the conductive rotary shaft 403 and meshes with the rotating bevel gear 401;

The other end of the transmission rotating shaft 403 is plugged and fixed with a passive pulley 408, and one end of the transverse shaft 406 is plugged and fixed with a driving pulley 407.

[0059] The eccentric rubber wheel 504 is provided with an elastic process groove 507 at the far end relative to the eccentric rotating shaft 503.

[0060] When the horizontal axis 406 rotates, it can coaxially drive the rotation of the driving pulley 407. The driving pulley 407 can drive the transmission bevel gear 404 to keep rotating in the same direction as the horizontal axis 406 through the coordinated transmission formed by the belt 409 and the driven pulley 408.

[0061] The coordinated transmission formed by the rotating bevel gear 401 and the conducting bevel gear 404 can drive the rotating bevel gear 401 and the conducting bevel gear 404 to rotate in opposite directions relative to each other, so that the eccentric tank 201 and the blanking tower 312 can rotate in opposite directions relative to each other when viewed from above.

[0062] Preferably, if Fig.10 and Fig.11As shown, in order to prevent the material dropping tower 312 from free rotation during the material shaking process in the external space of the eccentric tank 201, a safety clamping column assembly 6 is provided between the side of the sliding seat 302 and the top of the middle fixed seat 103, and the synchronous rotating wheel 601 is plugged and fixed at one end of the horizontal axis 406, and a side sliding seat 602 is fixed on the side of the sliding seat 302, and the spring-cage sliding column 603 and the pushed sliding column 604 are both slidably connected in the side sliding seat 602, and the tops of the spring-cage sliding column 603 and the pushed sliding column 604 are A transverse connecting plate 605 is fixed together, a vertical sleeve 606 is fixed to the top surface of the side sliding seat 602, a top clamping plate 607 is fixed to the top of the vertical sleeve 606, a compression spring 608 is installed between the top of the middle part of the transverse connecting plate 605 and the bottom end of the top clamping plate 607, and an elastic clamping seat 610 is fixedly connected to the bottom end of the elastic clamping slide column 603; and under the action of the elastic force of the compression spring 608, when there is no external force pushing the transverse connecting plate 605, the elastic clamping seat 610 is in a position of elastic locking with the synchronous rotating wheel 601. The fixed column 609 is fixedly connected to the top of the middle fixed seat 103, and its position is opposite to the pushed sliding column 604, so that before the sliding seat 302 moves downward to mesh with the side connecting bevel gear 505 and the active bevel gear 506, that is, before the blanking tower 312 extends into the eccentric tank 201 and is in place, the pushed sliding column 60 4 has been in contact with the top of the fixed column 609 in advance. As the sliding seat 302 continues to move downward, it can form a reverse push on the pushed sliding column 604 and the horizontal connecting plate 605, driving the spring seat 610 to disengage from the synchronous rotating wheel 601, so that after the side connecting bevel gear 505 and the active bevel gear 506 are meshed in place, the horizontal axis 406 is in a free rotation state, which facilitates the blanking tower 312 to extend into the eccentric tank 201 and form a coordinated transmission with the rotation of the eccentric tank 201.
