Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, in particular to a multi-stage treatment device for laboratory waste liquid. Background Art

[0002] Laboratory waste liquid is composed of a combination of various treatment equipment. The waste liquid is first filtered, then chemically treated, and finally finely filtered. Fine filtration includes large particle dirt filtration and membrane filtration.

[0003] The following technical problems may arise when using existing membrane filtration equipment:

[0004] 1. When the water flow rate is too large, the membrane filaments will be too tight, causing the membrane filaments to stretch, resulting in stress exceeding the elastic limit of the material, thereby causing permanent deformation or breakage;

[0005] 2. Because the membrane filter is composed of multiple groups of membrane filaments, and the water flow direction is fixed, the pollution degree of multiple groups of membrane filaments will be uneven, thus affecting the overall flux and operating efficiency;

[0006] 3. The membrane filaments between the membrane filament groups are loose and numerous. After the dirt is adsorbed, the adhesion between the membrane filaments increases, which easily causes the aggregation of the membrane filaments, thereby affecting the contact area between the membrane filaments and the water flow, thereby affecting the flux of the membrane filaments and the operating efficiency of water filtration.

[0071] A controller is fixed to the outer wall of the second filter cartridge 22 , and the controller is electrically connected to the first motor 52 , the second motor 81 and the flow sensor.

[0072] Working principle:

[0073] The liquid after preliminary blending and filtration is fed into the filter mechanism 1 through the first liquid inlet pipe 13. The multi-layer filter screen and activated carbon filter the liquid. The liquid then enters the interior of the second filter cartridge 22 through the second liquid inlet pipe 24. The flow sensor obtains the flow data of the liquid and then transmits the data to the controller. After obtaining the flow data, the controller adjusts the tightness of the membrane filament 36 according to the flow rate to avoid excessive flow rate causing the membrane filament 36 to be stretched due to excessive tightness, resulting in stress exceeding the elastic limit of the material, thereby causing permanent deformation or fracture. The adjustment steps are as follows:

[0074] The starting motor 52 drives the gear 53 to rotate forward. The forward rotation of the gear 53 satisfies the direction of the rotation of the one-way gear 2 42 to drive the reciprocating screw 41. The reciprocating screw 41 drives the movable frame 44 to move upward. The upward movement of the movable frame 44 pushes the bottom plate 34 and the square rod 33 to move upward. The upward movement of the bottom plate 34 causes the membrane wire mounting plate 35 to move upward to relax the membrane wire 36. After the flow rate decreases, the movable frame 44 moves downward to restore the membrane wire 36. In addition, the membrane wire with increased relaxation swings under the high flow rate of water to achieve a self-cleaning effect.

[0075] During the filtration process, the motor 152 is started to drive the gear 153 to rotate in reverse. The reversal of the gear 153 satisfies the direction in which the one-way gear 132 drives the rotating shaft 131 to rotate. The rotating shaft 131 drives the square rod 133 to rotate. The square rod 133 drives the bottom plate 34 to rotate. The bottom plate 34 drives multiple membrane wire mounting plates 135, telescopic rods 37, membrane wires 36, membrane wire mounting plates 238, pipe fittings 139, gear 2310 and top plate 313 to rotate. The pipe fittings 139 drive the collection box 315 and pipe fittings 2316 to rotate. The second gear 310 gradually meshes with the arc-shaped rack 311 as it follows the revolution and then rotates. The rotation of the second gear 310 drives the pipe 1 39, the second membrane wire mounting plate 38, the telescopic rod 37, the membrane wire 36 and the first membrane wire mounting plate 35 to rotate the membrane wire 36 facing inward toward the second liquid inlet pipe 24. By rotating the membrane wires 36 at different positions toward the water flow, the membrane wires 36 are evenly contacted with the water flow, evenly filtering dirt, and avoiding uneven contamination of the membrane wires 36 at multiple positions that affects the overall flux.

[0076] During operation, the membrane filaments 36 need to be in a slightly relaxed state. However, due to the small diameter of the membrane filaments 36 and the dense installation, the membrane filaments 36 may accumulate and stick together. Especially when there is a lot of dirt, the adhesion is stronger. After sticking together, the contact surface with the water flow is reduced, thereby affecting the water filtration flux. Therefore, it is necessary to comb the membrane filaments 36 after a period of use to reduce its adhesion and the dirt on the surface, thereby increasing the flux of the membrane filaments 36 and improving the operation efficiency. The specific steps are as follows:

[0077] The controller stops the operation of motor 1 52, so that the membrane wire 36 stops rotating, and starts motor 2 81 to drive gear 3 82 to rotate. The rotation of gear 3 82 drives gear 4 72 and gear 5 62 to rotate at the same time. The rotation of gear 5 62 drives reciprocating screw 2 61 to rotate, so that the movable plate 63 moves downward, driving the square rod 2 76, the annular mounting frame 65 and the combing teeth 66 and other structures to move downward. When the combing teeth 66 move downward, they gradually disengage from the trapezoidal plate 68. During the disengagement process, the spring telescopic rod 610 pulls the mounting block 69 and the combing teeth 66 toward the membrane wire 36 and then inserts them between the membrane wires 36. When the combing teeth 66 disengage from the trapezoidal plate 68, the combing teeth 66 are completely inserted between the membrane wires 36. Then the annular mounting frame 65 moves downward and contacts the slope at the top of the dial plate 73. If it continues to move downward, the spring 2 75 is compressed. The rotating dial plate 73 causes the annular mounting frame 65 to repeatedly squeeze the spring 2 75, driving multiple combing teeth 66 to shake back and forth. The combing teeth 66 shake while combing up and down, causing the combing teeth 66 to vibrate around Part of the dirt on the membrane wire 36 is separated, the controller starts the sewage pump 613 to generate suction and transmits it to the extraction pipe 611 through the collecting ring 612, the extraction pipe 611 transmits the suction to the plug-in port 67, the dirt enters the plug-in port 67 and then enters the extraction pipe 611 and the collecting ring 612, and is then sucked into the filter cartridge 12 by the sewage pump 613 for re-filtration. After combing back and forth, the trapezoidal plate 68 separates the combing teeth 66 from the membrane wire 36 through the inclined surface, and then the motor 2 81 is turned off and started. Motor 1 52 reverses gear 1 53, causing multiple groups of membrane filaments 36 to revolve and rotate, and then continues to start motor 2 81 to comb the position. The membrane filament gathering and combing mechanism 6 cooperates with the membrane filament uniform utilization mechanism 3 to comb the membrane filaments 36 at different positions to avoid adhesion of the membrane filaments 36 and ensure the flux of the membrane filaments 36. In the process of combing, the dirt on the surface of the membrane filaments 36 is cleaned to reduce the pollution on the surface of the membrane filaments 36, ensure the flux of the membrane filaments 36, and improve the operating efficiency of water filtration.
