Description

Technical Field

[0001] This utility model relates to the field of Y-type molecular sieve technology, specifically to a solid-liquid separation treatment device for Y-type molecular sieve modified slurry. Background Technology

[0002] Y-type molecular sieves are microporous crystalline materials with a framework structure. They possess high adsorption capacity and strong thermal stability, and are widely used in the petrochemical industry. To adapt Y-type molecular sieves to different catalytic reactions, they often undergo dealumination treatment to improve their hydrothermal stability and adjust their acidity. During Y-type molecular sieve modification, solid-liquid separation of the modified slurry is frequently required. Existing solid-liquid separation methods for Y-type molecular sieve modified slurries use a vacuum filter. During separation, solids remain in the vacuum funnel, forming a filter cake. As filtration continues, the filter cake in the vacuum funnel gradually thickens, affecting the filtration speed. Therefore, when large quantities of slurry require solid-liquid separation, the filter cake in the vacuum funnel needs frequent cleaning and recovery. However, existing vacuum filters often cannot continue operating after cleaning and recovering the filter cake, reducing the efficiency of solid-liquid separation of Y-type molecular sieve modified slurries.

[0003] Therefore, we have designed a solid-liquid separation treatment device for Y-type molecular sieve modified slurry. Utility Model Content

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 and Figure 2In this embodiment: A solid-liquid separation treatment device for Y-type molecular sieve modified slurry includes a mounting frame 1. Two suction funnels 2 are mounted on the top platform of the mounting frame 1. A horizontal perforated plate 2-1 is installed inside the suction funnel 2, and a filter cloth 11 is covered on the perforated plate 2-1. The filter cloth 11 is replaceable. A horizontal ring 3 is installed in the middle of the mounting frame 1. A suction flask 4 is placed on the ring 3. A three-way pipe 5 is provided between the suction flask 4 and the two suction funnels 2. The main pipe of the three-way pipe 5 is connected to the liquid inlet 4-1 at the top of the suction flask 4. The two branch pipes of the three-way pipe 5 are respectively connected to the outlets of the two suction funnels 2. A first valve 6 is installed on each of the two branch pipes of the three-way pipe 5. The two branch pipes of the three-way pipe 5 are connected to the outlets of the two suction funnels 2. Sealing rings are provided at the joints, as well as at the connection between the main pipe of the three-way pipe 5 and the filtration bottle 4. When the slurry is separated into solid and liquid, the slurry can be poured into two filtration funnels 2 for simultaneous filtration. During this process, the user can add slurry to the two filtration funnels 2 at any time. When it is necessary to clean and recover the filter cake in the funnel, clean and recover the filter cake in one of the filtration funnels 2 first. Do not add slurry to the funnel to be cleaned temporarily. After the liquid in the funnel has drained, close the first valve 6 on the branch pipe of the three-way pipe 5 connected to the funnel. Then clean and recover the filter cake in the funnel and replace the filter cloth 11 in the funnel. Finally, add slurry to the funnel and open the closed first valve 6. Then, repeat the same operation to clean and recover the filter cake in the other filtration funnel 2.

[0018] The bottom of the filtration flask 4 is provided with a drain port 4-2, and a second valve 7 is installed at the drain port 4-2. The side of the filtration flask 4 is provided with an air inlet 4-3 and an exhaust port 4-4. A third valve 8 is installed at the air inlet 4-3, and a one-way valve is installed at the exhaust port 4-4. When using the device, the exhaust port 4-4 is connected to a vacuum pump with a sealing tube. After the vacuum pump draws the air pressure into the filtration flask 4, a negative pressure can be formed above the mesh plate 2-1 of the filtration funnel 2, thereby accelerating the solid-liquid separation of the slurry in the filtration funnel 2. Opening the third valve 8 can quickly restore the air pressure in the filtration flask 4, and opening the second valve 7 can discharge the filtered liquid in the filtration flask 4.

[0019] A liquid storage tank 9 is placed on the bottom platform of the mounting frame 1. The liquid storage tank 9 is located directly below the filtration bottle 4. The liquid storage tank 9 is used to receive the liquid in the filtration bottle 4. All four support columns of the mounting frame 1 are equipped with casters 10 at their bottoms, which can facilitate the user to move the position of the device.

[0020] The working principle and usage process of this utility model are as follows: When using this Y-type molecular sieve modified slurry solid-liquid separation treatment equipment, first connect the exhaust port of the suction flask 4 to an external vacuum pump with a sealing pipe, open the two first valves 6, and close the second valve 7 and the third valve 8. Pour the slurry to be treated into the two suction funnels 2, then turn on the vacuum pump. The slurry is filtered through the filter cloth 11 in the funnel, and the solids remain on the filter cloth 11. The liquid flows into the suction flask 4. The filter cake in the suction funnel 2 is cleaned and recycled every once in a while. When cleaning and recycling the filter cake, the filter cake in one of the suction funnels 2 is cleaned and recycled first. The funnel to be cleaned is not added to the funnel temporarily. Wait for the liquid in the funnel to be cleaned. After the filter cake has drained, close the first valve 6 on the branch pipe of the three-way pipe 5 connected to the funnel. Then clean and recover the filter cake in the funnel and replace the filter cloth 11 in the funnel. Finally, add slurry to the funnel and open the closed first valve 6. Then, perform the same operation to clean and recover the filter cake in another suction filtration funnel 2. During the cleaning and recovery of the filter cake, the equipment can continue to work, which greatly improves the solid-liquid separation efficiency of the slurry. After the solid-liquid separation of the slurry is completed, first turn off the vacuum pump, then open the third valve 8 to quickly restore the air pressure in the suction filtration bottle 4 to normal. Finally, open the second valve 7 to discharge the liquid in the suction filtration bottle 4 into the storage tank 9.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
