[0002] The template agent recovery device in molecular sieve production is used to recover and reuse the template agent from the reaction system. The template agent is an organic molecule used to guide the structure in molecular sieve synthesis and usually needs to be removed after synthesis. The template agent recovery device usually uses solvent extraction to separate and recover the template agent from the molecular sieve synthesis product. The template agent recovery device can use membrane technology to separate the template agent from the liquid. The liquid can first pass through a filter to remove large solid particles.

[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution for a template agent recovery device for molecular sieve production:

[0022] Embodiment 1:

[0023] Such as Figures 1-3As shown in the figure, a template agent recovery device for molecular sieve production includes a membrane separation box body 1, a solid-liquid separation box 2, a control panel 3 and a treatment pipe 4. The solid-liquid separation box 2 is arranged on the top of the membrane separation box body 1, the control panel 3 is arranged on the front of the membrane separation box body 1, the treatment pipe 4 is arranged on one side of the solid-liquid separation box 2, a servo motor 5 is arranged on one side of the solid-liquid separation box 2, the output shaft of the servo motor 5 is drivingly connected with a cam 6, a fixed rod 7 is arranged inside the solid-liquid separation box 2, a lifting block 8 is sleeved on one end of the fixed rod 7, a convex plate 9 is arranged on one side of the lifting block 8, a U-shaped plate 10 is fixedly installed on one side of the convex plate 9, a first separation rack 11 is arranged at the bottom end of the U-shaped plate 10, a second separation rack 13 is arranged at the bottom of the first separation rack 11, a first separation net 14 is arranged inside the second separation rack 13. After the convex part of the cam 6 applies an upward force to the bottom of the convex plate 9, it will drive the lifting block 8 to move upward at one end of the fixed rod 7, and the first separation rack 11 and the second separation rack 13 can move upward. After the return spring 18 returns to its initial state, the two will move downward again. Through the up and down movement of the two, the time for solid particles to block the pore diameter is shortened.

[0024] Embodiment 2:

[0025] On the basis of Embodiment 1, as Figure 1 and Figure 4 shown, the lifting block 8 is movably sleeved on one end of the fixed rod 7, the convex plate 9 is located at the top of the cam 6, a return spring 18 is wound around the outside of the fixed rod 7, and one end of the return spring 18 is fixedly connected to the top end of the lifting block 8. In the template agent recovery device for molecular sieve production of the present utility model, by setting the fixed rod 7, the compression bar 12, the shielding plate 16 and the side plate 17, after the convex plate 9 receives an upward force, the lifting block 8 will move on one end of the fixed rod 7, and the return spring 18 will be compressed and deformed under force. When the cam 6 is not in contact with the convex plate 9, the return spring 18 will return to its initial state, and the lifting block 8 will move downward.

[0026] Working principle: The template agent recovery device in molecular sieve production is used to recover and reuse the template agent from the reaction system. The template agent is an organic molecule used to guide the structure in molecular sieve synthesis and usually needs to be removed after synthesis. The template agent recovery device usually uses solvent extraction to separate and recover the template agent from the molecular sieve synthesis product. The template agent recovery device can use membrane technology to separate the template agent from the liquid. The liquid can first pass through a filter to remove large solid particles. First, use solvent extraction to separate and recover the template agent from the molecular sieve synthesis product, and then send it to the inside of the membrane separation box 1 through the treatment pipe 4 for continuous membrane separation. The liquid sent to the inside of the solid-liquid separation box 2 may contain solid particles. The unfiltered solid particles may mix into the recovered template agent, which will affect the efficiency of its regeneration process and make the recovered template agent unable to reach the expected purity. Therefore, it is particularly important to design a template agent recovery device for molecular sieve production. The extracted liquid will be diverted to the inside of the solid-liquid separation box 2 through the treatment pipe 4. The liquid passes through the second separation net 15 and the first separation net 14 in sequence. The pore size on the surface of the second separation net 15 is larger than that on the surface of the first separation net 14. The mutual cooperation of the two can filter the solid particles in the liquid twice and improve the quality of solid particle filtration. After starting the servo motor 5, it can drive the cam 6 to rotate. After the convex part of the cam 6 exerts an upward force on the bottom of the convex plate 9, it will drive the lifting block 8 to move upward at one end of the fixed rod 7. The first separation frame 11 and the second separation frame 13 can then move upward. After the return spring 18 returns to its initial state, the two will move downward again. Through the up and down movement of the two, the solid particles will oscillate back and forth on the surfaces of the first separation net 14 and the second separation net 15, shortening the time for the solid particles to block the pores and improving the filtration efficiency of the two, thus improving the quality of the template agent recovery device. After the convex plate 9 receives an upward force, the lifting block 8 will move at one end of the fixed rod 7, and the return spring 18 will be compressed and deformed under force. When the cam 6 is not in contact with the convex plate 9, the return spring 18 will return to its initial state, and the lifting block 8 will move downward. The first separation frame 11 and the second separation frame 13 are connected by multiple compression bars 12. Under the connection of the U-shaped plate 10, the first separation frame 11 and the second separation frame 13 move up and down simultaneously. The shielding plate 16 can cover the top of the solid-liquid separation box 2, and the two side plates 17 can cover both sides of the top of the solid-liquid separation box 2.
