Description

Technical Field

[0001] The utility model relates to the technical field of catalyst recovery, in particular to a recovery device for a hydration catalyst. Background Art

[0002] In many chemical production processes, the hydration reaction is widely used, and the hydration reaction usually requires the use of a catalyst to improve the reaction efficiency and selectivity. In order to reduce the consumption of the catalyst, the catalyst in the hydration reaction is usually recovered. In the prior art, the catalyst recovery device mainly includes a filtration unit, an adsorption unit, an elution unit and a regeneration unit. In the recovery process, the reactants generated by the hydration reaction need to be introduced into the filtration unit to remove large and small particles therein, and then introduced into the adsorption unit, where a specific adsorbent is used to adsorb the catalyst in the filtered solution, and then introduced into the elution unit, where a specific eluent is used to elute the catalyst adsorbed on the adsorbent, and finally the used adsorbent is regenerated through the regeneration unit to restore its adsorption performance for recycling.

[0003] The adsorbent is usually statically installed in the adsorption unit. When the reactants of the hydration reaction are introduced into the adsorption unit, the adsorbent will absorb the catalyst in the reactants. However, during the absorption, the adsorbent and the reactants are in a relatively static state, and the adsorption effect is poor, which takes a lot of time and reduces the recovery efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0027] Referring to Figures 1 - 7, A hydrated catalyst recovery device, including a box body 1, a liquid inlet pipe and a liquid outlet pipe are connected to the box body 1, a valve is installed on the liquid inlet pipe, a jack is opened on the upper surface of the box body 1, and a mounting seat 2 is inserted into the jack through a mounting component. The lower surface of the mounting seat 2 is rotatably installed with a rotating shaft 3 through a support block, a cross 4 is fixedly sleeved on the rotating shaft 3, and a plurality of adsorption blocks 20 are installed on the cross 4. A rotating rod 5 is horizontally rotatably installed on the side surface of the box body 1, one end of the rotating rod 5 is connected to one end of the rotating shaft 3 through a connecting component, and a driving motor 6 is fixedly installed on the side surface of the box body 1. The output shaft of the driving motor 6 is connected to one end of the rotating rod 5.

[0028] By opening the valve, the reactant after the hydration reaction enters the box body 1 through the liquid inlet pipe, then start the driving motor 6 to drive the rotating rod 5 to rotate, and then drive the rotating shaft 3 to rotate through the connecting component. During the rotation of the rotating shaft 3, it will drive the cross 4 to rotate in the box body 1, thereby driving a plurality of adsorption blocks 20 to rotate around the rotating shaft 3. During the rotation of the adsorption blocks 20, it will accelerate the flow rate between the adsorption blocks 20 and the reaction products, thereby effectively accelerating the speed of the adsorption blocks 20 absorbing the catalyst, and then improving the catalyst recovery efficiency.

[0029] A plugging component for plugging the liquid outlet pipe is provided in the box body 1. The plugging component includes two first spring rods 15 symmetrically and fixedly installed inside the box body 1, a sealing block 16 fixedly installed at the lower ends of the two first spring rods 15, and a transmission component for driving the sealing block 16 to move vertically downward. The sealing block 16 is located directly above the liquid outlet pipe. The transmission component includes a support rod 17 fixedly installed on the sealing block 16 and a second spring rod 18 fixedly installed on one of the support blocks. The lower end of the second spring rod 18 is located above the support rod 17, and the elastic coefficient of the second spring rod 18 is greater than that of the first spring rod 15.

[0030] The sealing block 16 is supported by the two first spring rods 15 and is located above the liquid outlet pipe. When the mounting seat 2 is installed on the box body 1, the lower end of the second spring rod 18 installed on the support block will contact the support rod 17. Since the elastic coefficient of the second spring rod 18 is greater than that of the first spring rod 15, it will drive the sealing block 16 to move vertically downward through the support rod 17, and the first spring rod 15 is stretched until the sealing block 16 plugs one end of the liquid outlet pipe, and then the second spring rod 18 will start to be compressed, so as to ensure that the sealing block 16 can plug the discharge pipe when the adsorption block 20 adsorbs the catalyst.

[0031] The connecting component includes two L-shaped fixing blocks 7 symmetrically and fixedly installed on the upper surface of the box body 1, a handle 8 fixedly installed on the upper surface of the mounting seat 2, and two positioning pins 9. First pin holes are opened at both ends of the handle 8, second pin holes are opened on both fixing blocks 7, and the positioning pins 9 are inserted into the first pin holes and the second pin holes.

[0032] The mounting base 2 is inserted into the jack, and at the same time, one end of the positioning pin 9 is inserted into the first pin hole and the second pin hole to complete the installation of the mounting base 2. After the catalyst adsorption is completed, the positioning pin 9 is detached from the handle 8 and the fixed block 7, and then the mounting base 2 is removed from the box body 1, so as to take out the adsorption block 20 from the box body 1 for elution. During the disassembly process of the mounting base 2, the second spring rod 18 will be driven to separate from the support rod 17. At this time, under the action of the elastic force of the first spring rod 15, the sealing block 16 is driven to move upward to open the liquid outlet pipe.

[0033] A cylindrical groove is formed at one end of the rotating rod 5 close to the rotating shaft 3. The connecting component includes a hexagonal column 10 slidably inserted into the cylindrical groove, a telescopic spring 11 fixedly installed at one end of the hexagonal column 10, and a pulling component for driving the hexagonal column 10 to move. One end of the telescopic spring 11 is fixedly connected to the inner wall of the cylindrical groove. A hexagonal groove 12 is formed at one end of the rotating shaft 3 close to the rotating rod 5. One end of the hexagonal column 10 is inserted into the hexagonal groove 12. An L-shaped moving hole 13 communicating with one end of the cylindrical groove is formed on the surface of the rotating rod 5. The end of the moving hole 13 away from the cylindrical groove is located outside the box body 1. The pulling component includes a pull rod 14 slidably installed in the moving hole 13. One end of the pull rod 14 is fixedly connected to the hexagonal column 10, and the other end passes through the box body 1.

[0034] Under the action of the elastic force of the telescopic spring 11, one end of the hexagonal column 10 is inserted into the hexagonal groove 12. Thus, when the rotating rod 5 rotates, the rotating shaft 3 can be driven to rotate through the hexagonal column 10. When the adsorption block 20 needs to be taken out, the pull rod 14 is pulled to drive the hexagonal column 10 to move into the cylindrical groove, the telescopic spring 11 is compressed, and one end of the hexagonal column 10 is removed from the hexagonal groove 12 to release the connection between the rotating rod 5 and the rotating shaft 3.

[0035] A plurality of spoiler plates 19 are obliquely and fixedly installed on the cross 4. Circular holes are formed in each of the plurality of spoiler plates 19. During the rotation of the cross 4, the spoiler plates 19 will be driven to rotate around the rotating shaft 3. Since the spoiler plates 19 are obliquely arranged, the plurality of spoiler plates 19 can drive the reactants in the box body 1 to flow, further accelerating the absorption of the catalyst.

[0036] In the present utility model, the driving motor 6 is started to drive the rotating rod 5 to rotate, and then the rotating shaft 3 is driven to rotate through the connecting component. During the rotation of the rotating shaft 3, the cross 4 will be driven to rotate in the box body 1, so as to drive the plurality of adsorption blocks 20 to rotate around the rotating shaft 3. During the rotation of the adsorption blocks 20, the flow rate between the adsorption blocks 20 and the reaction will be accelerated, thus effectively accelerating the speed of the adsorption blocks 20 absorbing the catalyst, and further improving the catalyst recovery efficiency.

[0037] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
