Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and more specifically, to a wastewater recovery device for phenolic resin ball production and its usage method. Background Technology

[0002] Phenolic resin, also known as Bakelite, is originally a colorless or yellowish-brown transparent substance. It is often marketed with coloring agents to appear in red, yellow, black, green, brown, blue, and other colors, and comes in granular or powder form. It is resistant to weak acids and weak alkalis, but decomposes in strong acids and corrodes in strong alkalis. It is insoluble in water but soluble in organic solvents such as acetone and alcohol. It is obtained by the condensation polymerization of phenolic resin or its derivatives. Wastewater from phenolic resin production requires treatment and recycling.

[0003] For example, a phenolic resin production wastewater treatment and recycling device with announcement number CN215327380U can filter impurities, but it does not have the function of collecting and storing impurities, which causes impurities to accumulate on the filter screen and easily cause filter screen blockage. In addition, the mixing method of the mixed agent is fixed and cannot be changed, which reduces the mixing effect. Summary of the Invention

[0016] According to another aspect of the present invention, a method for recycling wastewater from the production of phenolic resin balls is provided.

[0017] The method for recycling the wastewater from the production of phenolic resin balls includes the following steps:

[0018] Wastewater is introduced into the upper chamber of the tank through the inlet pipe;

[0019] When the interception unit is activated, it pushes the impurities contained in the wastewater entering the upper chamber to the surrounding areas. The intercepted impurities fall from the filter ring into the interlayer formed between the inner cylinder and the inner wall of the barrel.

[0020] Wastewater free of impurities enters the inner cylinder after being filtered through the first filter screen;

[0021] The compression section in the inner cylinder is activated, and the compression section generates spiral compression, which centrifugally mixes the wastewater and the incoming reagent inside.

[0022] The mixed liquid enters the lower chamber;

[0023] The actuating mechanism inside the lower chamber is activated to perform secondary mixing of the wastewater entering the chamber.

[0024] The mixed wastewater is discharged from the outlet pipe;

[0025] The collected impurities are removed by opening the window at the top of the barrel.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0027] 1. By dividing the tank into an upper chamber, a middle chamber, and a lower chamber, the interception section in the upper chamber intercepts and collects impurities in the wastewater into the interlayer in the middle chamber. Wastewater without impurities enters the middle chamber, where the internal compression section performs spiral compression treatment on the wastewater and reagents. Wastewater filtered down along with impurities in the interlayer enters the lower chamber, where the agitator in the lower chamber performs secondary mixing of the wastewater and reagents. This achieves the collection and treatment of impurities, avoids the situation where the first filter screen is blocked and cannot continue filtering, and thus improves the effectiveness of the device.

[0028] 2. The wastewater and chemicals are mixed by the compression section in the middle cavity and the agitation section in the lower cavity. The spiral compression and up-and-down swinging motion mix the wastewater and chemicals, improving the mixing effect and ensuring the effectiveness of wastewater treatment.

[0029] 3. The compression section of the present invention generates a spacing change through the eccentric rotation of the first and second spiral plates, realizing dual mixing of extrusion and centrifugal mixing. Compared with the single stirring of the prior art, the present invention has more uniform mixing and better effect; the agitator section further improves the mixing efficiency through horizontal axis stirring and vertical axis piston movement.

[0052] Example 2

[0053] A method for recycling wastewater from the production of phenolic resin balls includes the following steps:

[0054] S101: Wastewater is introduced into the upper cavity 7 inside the tank body 1 through the inlet pipe 2;

[0055] S103: Start the interception unit to operate. The interception unit pushes the impurities contained in the wastewater entering the upper chamber 7 to the surrounding areas. The intercepted impurities fall from the filter ring 11 into the interlayer formed between the inner cylinder 12 and the inner wall of the barrel 1.

[0056] S105: Wastewater without impurities enters the inner cylinder 12 after being filtered through the first filter screen 5;

[0057] S107: Start the compression section in the inner cylinder 12. The compression section generates spiral compression to centrifugally mix the wastewater and the incoming reagent inside.

[0058] S109: The mixed liquid enters the lower chamber 9;

[0059] S1011: Activate the actuating part in the lower chamber 9 to perform secondary mixing of the wastewater entering the chamber;

[0060] S1013: The mixed wastewater is discharged from the outlet pipe 3;

[0061] S1015: The collected impurities are removed by opening the window at the top of the barrel 1.

[0062] Detailed usage and function of this embodiment:

[0063] Wastewater is introduced into the upper cavity 7 of the tank 1 through the inlet pipe 2. Impurities in the wastewater also enter the upper cavity 7. The driver 28 is started, which drives the output shaft. The output shaft drives a set of drive rods 31 connected to the intersecting ends below the fixed block 27. After the output shaft rotates, the drive rods 31 connected to the side pull the drive rods 31 in linkage, thereby pushing the guide slider 34 to slide in the annular guide rail 26, pushing the brush roller 30 connected below to reciprocate in different circumferential ranges, such as... Figure 5 As shown, the motion trajectory of the drive rod 31 includes a, b, and c. With the fixed block 27 as the original endpoint, the reciprocating motion in the three range trajectories of a, b, and c causes the brush roller 30 below to reciprocate along with it, pushing the impurities contained in the internally injected wastewater to the periphery and entering the interlayer formed between the inner cylinder 12 and the inner wall of the barrel 1 through the filter holes of the filter ring 11.

[0064] The filter holes of the first filter screen 5 are set to a fine aperture. When intercepting impurities and pushing them, the brush roller 30 sweeps the impurities adhering to the first filter screen 5 to the periphery during the reciprocating motion, and they enter the interlayer through the aperture of the peripheral filter ring 11. Some of the wastewater without impurities seeps down through the aperture of the first filter screen 5 and enters the inner cylinder 12. The other part enters the interlayer together with the impurities through the aperture of the filter ring 11.

[0065] When motor 13 is started, it drives shaft 14 to rotate, which in turn drives turntable 22 to rotate. After turntable 22 rotates, side groove 21 drives protrusion 19, which in turn drives adapter plate 18 to rotate. Protrusions 17 on the other two sides of the bottom plate of adapter plate 18 slide within side groove 16. Because adapter plate 18 has a through hole in its center, the diameter of which is larger than the outer diameter of shaft 14, according to… Figure 9 As shown, the shaft 14 has an eccentric connecting end on the left side, which is at the bottom center of the bottom protrusion plate 20. When the shaft 14 rotates, it will drive the bottom protrusion plate 20 to rotate eccentrically. The adapter plate 18 slides in the side groove 16. After the turntable 22 rotates eccentrically, the top spiral plate 23 rotates and wobbles eccentrically in the spiral plate 24, causing the gap between the spiral plate 23 and the spiral plate 24 to repeatedly impact and deform. The gap between the two is constantly compressed and changed. Under the spiral compression of the two spiral plates, the incoming wastewater is squeezed and impacted. The centrifugal motion generated by the spiral compression will compress and mix the wastewater with the incoming reagent.

[0066] When motor 255 is started, it drives the fan wheel 36 connected to the output end to rotate. The end between the two fan wheels 36 is connected to the inverted T-shaped plate 37. When the fan wheel 36 rotates, it drives the inverted T-shaped plate 37 to move up and down. The inverted T-shaped plate 37 drives the connecting plates 39 set on both sides of the upper part to sway left and right. When the inverted T-shaped plate 37 moves up and down, the right fan-shaped side toothed plate 40 meshes with the single-sided toothed plate 42 and rotates up and down. After the left fan-shaped side toothed plate 40 rotates, it drives the double-sided toothed plate 41 to slide up and down. The left side tooth of the double-sided toothed plate 41 meshes with the gear 47, and the slide plate 49 slides up and down in the right groove of the U-plate 51. When the double-sided toothed plate 41 and the single-sided toothed plate 42 move up and down, they will push against the piston rod 43 to move up and down. The piston 44 moves up and down in the compression cylinder 45. The compression cylinder 45 generates Positive and negative pressure enter the right-side compression cylinder 45 through the connecting pipe. The positive and negative pressure generated in the two compression cylinders 45 rises upward, rushing out of the second filter screen 6 and the filter structure at the bottom of the inner cylinder 12 and entering the inner cylinder 12. When the wastewater and the agent inside the inner cylinder 12 are subjected to spiral compression and centrifugal motion, the gas rushing up from below provides a certain amount of oxygen and also has the effect of dispersing the wastewater and increasing the turbulence of the wastewater. The connecting plate 39 is pushed up and down by the inverted T-shaped plate 37 to achieve left and right swaying. The stirring rod 38 inserted in the middle of the side will be driven to flip together. During the flipping motion of the stirring rod 38, it will drive the wastewater falling into the jacket and the inner cylinder 12 to be stirred and mixed together. The stirring rod 38 achieves stirring in the horizontal axis direction, while the connecting plate 39, the double-sided toothed plate 41 and the single-sided toothed plate 42 achieve stirring in the vertical axis direction. The mixed wastewater is discharged from the outlet pipe 3.
