Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a wastewater treatment device for the glass fiber industry. Background Technology

[0002] Fiberglass products are typically modified with phenolic resin during production, resulting in wastewater often rich in phenol and other pollutants (COD). Currently, activated carbon is commonly added directly to the wastewater to adsorb phenol and COD. However, activated carbon adsorbs both phenol and COD, requiring prolonged settling in a sedimentation tank before solid-liquid separation. Simultaneously, the fiberglass wetting and washing processes also generate significant amounts of wastewater, necessitating the separation of dust and other solid impurities.

[0003] For example, the glass fiber wastewater treatment device disclosed in Chinese Patent Publication No. CN105016514B includes an equalization sedimentation tank, a coagulation tank, a reaction tank, a horizontal flow sedimentation tank, an intermediate water tank, a reclaimed water tank, a sludge tank, and a sludge conveying device, which efficiently treats glass fiber wastewater. However, in this application, the wastewater needs to settle in the horizontal flow sedimentation tank by relying on the gravity of the flocculants themselves, resulting in a long settling time. This leads to a long treatment time and low treatment efficiency for the glass fiber wastewater. Traditional centrifugal separation equipment causes solid impurities to be distributed in the circumferential direction of the centrifugal separator, making it inconvenient to discharge solid impurities. Therefore, this application provides a glass fiber industrial wastewater treatment device that solves the problem of long settling time in the wastewater treatment process of the prior art, facilitates the separation and discharge of solid impurities, and improves the solid-liquid separation efficiency of wastewater. Summary of the Invention

[0004] To address the above problems, the present invention provides a wastewater treatment device for the glass fiber industry.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a glass fiber industrial wastewater treatment device, including a sedimentation tank body, the sedimentation tank body including a through cylindrical part and a converging part, the width of the converging part gradually decreasing in the direction away from the cylindrical part, a first separation tank and a second separation tank are provided inside the cylindrical part, the first separation tank is located inside the second separation tank, and V-shaped partition plates are provided inside the first separation tank, inside the second separation tank and inside the converging part;

[0006] The first separation box and the cylindrical part are eccentrically positioned, as are the second separation box and the first separation box.

[0007] As an optimization, the cylindrical portion has a side opening on the side away from the retracting portion, and an elastic shell is connected inside the side opening. An adjustment component is provided on the outside of the cylindrical portion, and the outer end of the adjustment component is connected to the elastic shell.

[0008] As an optimization, the first separation box and the second separation box are eccentrically arranged, and the axes of the first separation box, the second separation box, the cylindrical part and the retracting part are all located on the same straight line;

[0009] The eccentricity direction of the first separation box and the cylindrical part is opposite to that of the second separation box and the cylindrical part.

[0010] As an optimization, the height of the partition plate is less than the inner cavity height of the sedimentation tank body. The partition plates are respectively a first partition plate disposed inside the first separation tank, a second partition plate disposed inside the second separation tank, and a third partition plate disposed inside the gathering part.

[0011] The first partition plate divides the first separation box into a first sedimentation area and a first drainage area. The second partition plate divides the second separation box into a second sedimentation area and a second drainage area. The third partition plate divides the converging part into a third sedimentation area and a third drainage area. The bottom of the first sedimentation area, the bottom of the second sedimentation area, and the bottom of the third sedimentation area are all connected to a sewage pipe.

[0012] As an optimization, the upper part of the sedimentation tank body is provided with an inclined telescopic rod, which is connected to the upper part of the partition plate. When the telescopic rod is extended, the partition plate moves downward at an angle and contacts and seals with the bottom of the sedimentation tank body.

[0013] As an optimization, the adjustment assembly includes several telescopic cylinders fixed to the top of the sedimentation tank body. The length direction of the telescopic cylinder is arranged along the diameter direction of the cylindrical part. A connecting arm is fixed to the extended end of the telescopic cylinder. A connecting sleeve is provided in the middle of the elastic shell. The outer end of the connecting arm is connected to the connecting sleeve.

[0014] As an optimization, a water inlet pipe is connected to the top of the first separation box, and a drain pipe is connected to the upper part of the cylindrical portion.

[0015] As an optimization, a drive motor is connected to the lower side of the sedimentation tank body, and the output shaft of the drive motor is connected to the axial direction of the cylindrical part.

[0016] This solution provides a wastewater treatment device for the glass fiber industry, which has the following advantages:

[0017] The sedimentation tank body of this application is connected to a retractable part on the side, making the sedimentation tank body an eccentric structure. The sedimentation tank body is equipped with an eccentric first separation tank and a second separation tank. Driven by a drive motor, the wastewater inside the equipment is centrifuged eccentrically. The wastewater is centrifuged three times through the first separation tank, the second separation tank and the sedimentation tank body, realizing multi-stage separation treatment of wastewater. The eccentric centrifugation makes the centrifugal force of the device unevenly distributed, promoting the efficient separation of solid impurities and wastewater. Attached Figure Description

In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figure 1-5As shown, a glass fiber industrial wastewater treatment device includes a sedimentation tank body 1. The sedimentation tank body 1 includes a through cylindrical part 4 and a converging part 5. The width of the converging part 5 gradually decreases in the direction away from the cylindrical part 4. A first separation tank 2 and a second separation tank 3 are provided inside the cylindrical part 4. The first separation tank 2 is located inside the second separation tank 3. V-shaped partition plates are provided inside the first separation tank 2, inside the second separation tank 3, and on the inner side of the converging part 5.

[0026] The first separation box 2 and the cylindrical part 4 are eccentrically positioned, as are the second separation box 3 and the first separation box 2.

[0027] The first separation box 2 and the second separation box 3 can be arranged eccentrically with the cylindrical part 4 in any manner to promote the overall force balance of the device, such as Figure 5 As shown, the axis of the first separation box 2 is biased to the left of the axis of the cylindrical part 4, and the axis of the second separation box 3 is biased to the right of the axis of the cylindrical part 4.

[0028] The cross-section of the sedimentation tank body 1 is cam-shaped, that is, one side has a larger diameter and the other side has a smaller diameter, and the cylindrical part 4 and the converging part 5 have a smooth transition.

[0029] In the initial state, the partition plate does not contact the inner wall of the device, and there is a gap between the lower end of the partition plate and the inner bottom of the sedimentation tank body 1. There is also a gap between the side wall of the partition plate and the inner wall of the device shell, so that the partition plate can be tilted downward to contact the side wall and bottom of the device.

[0030] like Figure 1 As shown, the cylindrical part 4 has a side opening on the side away from the retracting part 5, and an elastic shell 6 is connected inside the side opening. An adjustment component is provided on the outside of the cylindrical part 4, and the outer end of the adjustment component is connected to the elastic shell 6.

[0031] The elastic shell 6 is preferably made of a material with a certain elasticity, such as rubber. The edge of the elastic shell 6 is sealed to the side opening. The adjustment component can lift the middle part of the elastic shell 6 outward, thereby increasing the diameter of the side opening of the cylindrical part 4 and providing counterweight to the retracting part 5.

[0032] like Figure 4 As shown, the first separation box 2 and the second separation box 3 are eccentrically arranged, and the axes of the first separation box 2, the second separation box 3, the cylindrical part 4 and the converging part 5 are all located on the same straight line;

[0033] The eccentricity of the first separation box 2 and the cylindrical part 4 is opposite to that of the second separation box 3 and the cylindrical part 4.

[0034] The shaft of the first separation box 2 and the shaft of the second separation box 3 are respectively located on both sides of the shaft of the cylindrical part 4.

[0035] like Figure 4 and Figure 5 As shown, the height of the partition plate is less than the inner cavity height of the sedimentation tank body 1. The partition plates are respectively a first partition plate 7 disposed inside the first separation tank 2, a second partition plate 8 disposed inside the second separation tank 3, and a third partition plate 9 disposed inside the gathering part 5.

[0036] The first partition plate 7 divides the first separation box 2 into a first sedimentation zone 10 and a first drainage zone. The second partition plate 8 divides the second separation box 3 into a second sedimentation zone 11 and a second drainage zone. The third partition plate 9 divides the converging part 5 into a third sedimentation zone 12 and a third drainage zone. The bottom of the first sedimentation zone 10, the bottom of the second sedimentation zone 11, and the bottom of the third sedimentation zone 12 are all connected to a sewage pipe 13.

[0037] A drain valve is installed on the drain pipe 13. Taking the side with the smaller opening of the partition plate as the inner side, the upper part of the drain pipe 13 gradually opens and connects to the bottom surface of the first sedimentation zone 10. The connection structure between the second sedimentation zone 11, the third sedimentation zone 12 and the drain pipe 13 is the same. The opening width of the drain pipe 13 is not less than the width of the upper end of the drain pipe 13.

[0038] like Figure 4 As shown, the upper part of the sedimentation tank body 1 is provided with an inclined telescopic rod. The telescopic rod is connected to the upper part of the partition plate. When the telescopic rod is extended, the partition plate moves downward at an incline and contacts and seals with the bottom of the sedimentation tank body 1.

[0039] The telescopic rod includes a first telescopic rod connected to the first partition plate 7, a second telescopic rod connected to the second partition plate 8, and a third telescopic rod connected to the third partition plate 9. The fixed end of the telescopic rod is connected to the top of the sedimentation tank body 1.

[0040] like Figure 1 As shown, the adjustment assembly includes several telescopic cylinders 14 fixed to the top of the sedimentation tank body 1. The length direction of the telescopic cylinder 14 is arranged along the diameter direction of the cylindrical part 4. A connecting arm 15 is fixed to the extended end of the telescopic cylinder 14. A connecting sleeve 16 is provided in the middle of the elastic shell 6. The outer end of the connecting arm 15 is connected to the connecting sleeve 16.

[0041] The extended end of the telescopic cylinder 14 is located on the outside of the sedimentation tank body 1, and the connecting arm 15 is vertically arranged on the outside of the sedimentation tank body 1. When the telescopic cylinder 14 is shortened, the lower end of the connecting arm 15 pulls the middle part of the elastic outer shell 6 outward.

[0042] like Figure 2 and Figure 4 As shown, the top of the first separation box 2 is connected to a water inlet pipe 18, and the upper part of the cylindrical part 4 is connected to a drain pipe 19.

[0043] like Figure 4 As shown, the first separation tank 2 is provided with a first drain outlet on the side away from the first sedimentation zone 10, and the first drain outlet is connected to the interior of the second separation tank 3. The second separation tank 3 is provided with a second drain outlet on the side away from the second sedimentation zone 11, and the second drain outlet is connected to the interior of the sedimentation tank body 1.

[0044] Wastewater is directly discharged into the upper part of the first separation tank 2 through the inlet pipe 18. After centrifugation in the first separation tank 2, the relatively clear wastewater enters the second separation tank 3 through the first drain outlet. The wastewater is centrifuged a second time in the second separation tank 3. The wastewater with solid impurities separated is discharged into the sedimentation tank body 1 through the second drain outlet for a third centrifugation.

[0045] A drive motor 17 is connected to the lower side of the sedimentation tank body 1, and the output shaft of the drive motor 17 is connected to the axial direction of the cylindrical part 4.

[0046] During centrifugation, the distance between the first sedimentation zone 10 and the axis of the drive motor 17 is greater than the distance between the first drainage zone and the axis of the drive motor 17, the distance between the second sedimentation zone 11 and the axis of the drive motor 17 is greater than the distance between the second drainage zone and the axis of the drive motor 17, and the distance between the third sedimentation zone 12 and the axis of the drive motor 17 is greater than the distance between the cylindrical part 4 and the axis of the drive motor 17.

[0047] A circular guide bar can be installed at the bottom of the sedimentation tank body 1. The guide bar is coaxially arranged with the drive motor 17. A guide rail is installed on the lower side of the sedimentation tank body 1. The guide bar and the guide rail are slidably connected to each other to improve the stability of the device operation. At the same time, other support structures can also be installed on the outside of the device. The specific structure should be such that it does not affect the rotation of the sedimentation tank body 1.

[0048] How to use:

[0049] In practical use, the device drives the sedimentation tank body 1 to rotate via the drive motor 17, so that the first separation tank 2, the second separation tank 3 and the sedimentation tank body 1 rotate simultaneously.

[0050] During the centrifugation process, the telescopic cylinder 14 shortens, causing the extended end of the telescopic cylinder 14 to pull the upper end of the connecting arm 15 towards the axis of the cylindrical part 4, causing the lower end of the connecting arm 15 to pull the middle part of the elastic shell 6 outward, increasing the diameter of the cylindrical part 4 away from the gathering part 5, thus playing the role of counterweighting the gathering part 5.

[0051] Wastewater is continuously discharged into the first separation tank 2 through the inlet pipe 18. After the first centrifugation, the water in the first separation tank 2 enters the second separation tank 3 through the first drain outlet. After the second centrifugation, the water in the second separation tank 3 is discharged into the sedimentation tank body 1 through the second drain outlet. After the third centrifugation, the wastewater in the sedimentation tank is finally discharged out through the drain pipe 19. Solid impurities are discharged downward through the sewage pipe 13, thus realizing solid-liquid separation of wastewater.

[0052] The specific adjustment process for the separator plate during the centrifugation process described above is as follows:

[0053] During the centrifugation process, due to the weight of solid impurities, they move away from the axis of the drive motor 17 under the action of centrifugal force. Solid impurities inside the first separation box 2 enter the first sedimentation zone 10 through the gap between the first partition plate 7 and the inner wall of the first separation box 2, and accumulate inside the first sedimentation zone 10.

[0054] Solid impurities inside the second separation box 3 enter the second sedimentation zone 11 through the gap between the second partition plate 8 and the inner wall of the second separation box 3, and accumulate inside the second sedimentation zone 11.

[0055] Solid impurities inside the sedimentation tank body 1 are subjected to centrifugal force and enter the gathering part 5, and then enter the third sedimentation zone 12 through the gap between the third partition plate 9 and the inner wall of the gathering part 5.

[0056] After centrifugation for a period of time, the telescopic rod extends, causing the first partition plate 7 to contact the side wall and bottom of the first separation box 2, completely isolating the lower middle part of the first sedimentation zone 10 and the first drainage zone; the second partition plate 8 contacts the side wall and bottom of the second separation box 3, completely isolating the lower middle part of the second sedimentation zone 11 and the second drainage zone; the third partition plate 9 contacts the inner wall and bottom of the gathering part 5, completely isolating the lower middle part of the third sedimentation zone 12 and the third drainage zone, and the drain valve of the drain pipe 13 is opened, allowing solid impurities to be discharged downwards.

[0057] After the partition plate is lowered, the liquid level inside the main body of the device is not higher than the top of the partition plate, and the height of the drain pipe 19 is not higher than the wastewater liquid level.

[0058] The partition plate is operated at intervals by telescopic rods. After the solid impurities are discharged, the telescopic rods are shortened to reset the partition plate. This allows the centrifugal separation and discharge of solid impurities to be carried out simultaneously, enabling continuous treatment of glass fiber wastewater.
