Description

Technical Field

[0001] This utility model relates to the field of molecular sieve synthesis equipment technology, and in particular to a high-silica ZSM-5 molecular sieve synthesis mother liquor separation and recovery device. Background Technology

[0002] After the high-silicon ZSM-5 molecular sieve crystallization synthesis is completed, plate and frame filtration is performed to achieve solid-liquid separation. The mother liquor from the filtration contains effective components such as silicates, aluminates, and sodium oxide, but it also contains unfiltered materials and unreacted residues. If it is directly recycled, it will affect the crystallization of the molecular sieve and form impurities. If it is not recycled, on the one hand, the effective components in the mother liquor will not be recycled and will be wasted, and on the other hand, treating the mother liquor will increase the cost of wastewater treatment.

[0003] In existing technologies, filter plates are typically used to separate and recover mother liquor, removing materials and slag from the mother liquor. Filter plates need to be cleaned frequently during use, otherwise they are prone to clogging and affecting the filtration effect. Cleaning filter plates usually requires manual operation, which is time-consuming and labor-intensive, affecting production efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the prior art and provide a high-silica ZSM-5 molecular sieve synthesis mother liquor separation tank, which has good separation and filtration effect on the mother liquor and is easy to clean.

[0005] The purpose of this utility model is achieved as follows: A high-silica ZSM-5 molecular sieve synthesis mother liquor separation tank includes a tank body, a dosing port on one side of the upper part of the tank body, a drive motor on the top of the tank body, the output shaft of the drive motor extending into the tank body and connected to the rotating shaft of the separation and filtration mechanism inside the tank body, the separation and filtration mechanism including a centrifugal filter plate disposed in the swirling zone inside the tank body and a baffle in the static settling zone, the centrifugal filter plate being disposed above the baffle, an umbrella cap being disposed between the centrifugal filter plate and the baffle, and an outlet pipe extending from below the umbrella cap to the outside of the tank body and connected to the outlet.

[0006] In operation, the mother liquor to be treated is added into the tank through the dosing port. The mother liquor is then processed by an internal separation and filtration mechanism, separating impurities from the liquid and removing residual materials and unreacted slag. The filtered mother liquor is discharged through the outlet for recycling, while residual materials and slag are discharged through the slag outlet at the bottom of the tank. Compared with existing technologies, the advantages of this invention are: the separation and filtration mechanism uses centrifugal rotation to separate impurity particles from the liquid in the mother liquor, while simultaneously allowing the liquid to pass through the perforations on the separation and filtration mechanism and ultimately discharge it through the outlet pipe. This simultaneous separation and filtration of impurities and liquid in the mother liquor improves separation and filtration efficiency. During the rotation of the separation and filtration mechanism, small impurity particles can flow downwards with the liquid through the perforations or, under centrifugal force, fly out from the upper edge of the filter plate and settle freely. Larger impurity particles slide down the surface of the filter plate and settle to the bottom, ultimately being discharged through the slag outlet. The mother liquor separation tank of this device provides good separation and filtration, is less prone to clogging the filter plate, and is easy to clean.

[0007] Furthermore, the centrifugal filter plate includes several upper filter plates and lower filter plates arranged in opposite directions, and the upper filter plates and lower filter plates are radially connected to the rotating shaft.

[0008] Furthermore, the upper filter plate and the lower filter plate are provided with leakage holes.

[0009] Furthermore, the umbrella cap is arranged radially downwards from the top.

[0010] Furthermore, the tank body is provided with an insulation layer on the outside, and heating oil is injected into the interlayer between the insulation layer and the outer shell of the tank body through the oil injection port. The bottom of the tank body is provided with a heater for heating.

[0011] Furthermore, a thermometer is also installed on the tank.

[0012] Furthermore, the tank body is provided with a slag outlet at the bottom, and a valve is provided on the slag outlet, which is a solenoid valve or a manual valve.

[0013] Furthermore, the upper part of the tank is provided with a maintenance manhole, and the lower part of the tank is provided with a support frame. Attached Figure Description

Detailed Implementation

[0017] like Figure 1 , 2 The high-silica ZSM-5 molecular sieve synthesis mother liquor separation tank shown includes a tank body, a dosing port 4 on one side of the upper part of the tank body, a drive motor 1 on the top of the tank body, the output shaft of the drive motor 1 extends into the tank body and is connected to the rotating shaft 14 of the separation and filtration mechanism inside the tank body, the separation and filtration mechanism includes a centrifugal filter plate disposed in the swirling zone inside the tank body and a baffle 8 in the static settling zone, the centrifugal filter plate is disposed above the baffle 8, an umbrella cap 6 is disposed between the centrifugal filter plate and the baffle 8, and the bottom of the umbrella cap 6 extends out of the tank body through an outlet pipe and is connected to an outlet 7.

[0018] The centrifugal filter plate includes several upper filter plates 3 and lower filter plates 13 arranged in opposite directions. The upper filter plates 3 and lower filter plates 13 are radially connected to the rotating shaft 14. The upper filter plates 3 and lower filter plates 13 are provided with leakage holes 17. The upper filter plates 3 and lower filter plates 13 rotate with the rotating shaft 14 under the drive of the drive motor 1. During rotation, small particulate impurities can flow downward with the liquid through the leakage holes 17 and enter the static settling zone. They can also be rotated along the upper part of the upper filter plate 3 under the action of centrifugal force and fly out to settle freely. Large particulate impurities that cannot pass through the leakage holes 17 slide down the surface of the upper filter plates 3 and lower filter plates 13 and fall into the static settling zone below. Finally, the liquid is discharged through the liquid outlet pipe, and the particulate impurities are discharged through the slag outlet 10 at the bottom of the tank.

[0019] The umbrella cap 6 is arranged radially from top to bottom; some small particles of impurities falling from the filter plate holes 17 above slide down the surface of the umbrella cap 6 and settle in the static settling zone below.

[0020] The tank body is provided with an insulation layer 12. Heating oil is filled into the interlayer between the insulation layer 12 and the outer shell of the tank body through the oil filling port 15. A heater 9 for heating is provided at the bottom of the tank body. A thermometer 5 is also provided on the tank body. The heater 9 heats the heating oil to keep the tank body warm to meet the needs of use. The thermometer 5 monitors the temperature of the tank body and facilitates real-time adjustment of the heating temperature.

[0021] The tank has a slag outlet 10 at the bottom and a valve 11 on the slag outlet 10. The valve 11 is either a solenoid valve or a manual valve. The materials and slag separated and filtered from the mother liquor are discharged through the slag outlet 10. When the valve 11 is a solenoid valve, it can be opened at timed intervals to achieve automatic discharge and reduce the burden of manual operation.

[0022] The upper part of the tank is provided with a maintenance manhole 2, and the lower part of the tank is provided with a support frame 16; the maintenance manhole 2 facilitates maintenance personnel to carry out maintenance work.

[0023] In operation, the mother liquor to be treated is added to the tank through the dosing port 4. The drive motor 1 drives the rotating shaft 14 to rotate, causing the upper filter plate 3 and the lower filter plate 13 to rotate. During rotation, small particles of impurities can flow downwards with the liquid through the leakage holes 17, or they can fly out from the upper edge of the filter plate under the action of centrifugal force and settle freely. Large particles of impurities slide down the surface of the filter plate and settle to the bottom. Finally, the residual materials and unreacted slag in the mother liquor are discharged through the slag outlet 10 at the bottom of the tank after settling. The filtered mother liquor is discharged through the liquid outlet 7 for recycling. The mother liquor separation tank of this device separates impurities from the liquid in the mother liquor through rotational centrifugation. At the same time, the leakage holes on the separation filtration mechanism allow the liquid to pass through and finally be discharged through the liquid outlet pipe. The impurities and liquid in the mother liquor are separated and filtered simultaneously, which improves the separation and filtration efficiency and makes the filter plates less prone to clogging, reducing the burden of manual cleaning.
