Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a glass fiber industrial wastewater treatment device. Background Art

[0002] Glass fiber products are generally modified with phenolic resin during production. Therefore, a large amount of phenol and other pollutants (COD) are often concentrated in the wastewater produced by glass fiber production. Currently, the method of directly adding activated carbon to the wastewater is generally used to adsorb phenol and COD in the wastewater. While adsorbing phenol, activated carbon also adsorbs a large amount of COD. After adsorbing phenol and COD, activated carbon needs to be precipitated for a long time in the sedimentation tank, and solid-liquid separation is performed after the sedimentation is completed. At the same time, a large amount of wastewater is also generated during the impregnation and cleaning process of glass fibers, and solid impurities such as dust in the wastewater need to be separated.

[0003] For example, the glass fiber wastewater treatment device disclosed in Chinese Patent Publication No. CN105016514B includes a regulating sedimentation tank, a coagulation tank, a reaction tank, a horizontal flow sedimentation tank, an intermediate water tank, a reuse water tank, a sludge tank, a sludge conveying device, etc., which can efficiently treat the glass fiber wastewater. However, in this application, the wastewater needs to be precipitated in the horizontal flow sedimentation tank by the gravity of the flocculant, and the sedimentation time is long, resulting in a long treatment time for the glass fiber wastewater and low treatment efficiency. The traditional centrifugal separation equipment will cause the solid impurities to be distributed in the circumferential direction of the centrifugal separation equipment, which is inconvenient for the discharge of solid impurities. Therefore, the present application provides a glass fiber industrial wastewater treatment device to solve the problem of long sedimentation time in the wastewater treatment process in the prior art, facilitate the separation and discharge of solid impurities, and improve the solid-liquid separation efficiency of the wastewater.

[0022] The first separation box 2 and the second separation box 3 can be arranged with the cylindrical part 4 in any eccentric form 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 side of the axis of the cylindrical portion 4, and the axis of the second separation box 3 is biased to the right side of the axis of the cylindrical portion 4.

[0023] The transverse cross section of the sedimentation box body 1 is cam-shaped, that is, one side has a larger diameter and the other side has a smaller diameter, and there is a smooth transition between the cylindrical portion 4 and the contracted portion 5 .

[0024] 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 box body 1, and 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 move downward and contact the side wall and bottom of the device.

[0025] like Figure 1 As shown, a side opening is provided on the side of the cylindrical portion 4 away from the retracted portion 5 , and an elastic shell 6 is connected to the inside of the side opening. An adjustment component is provided on the outside of the cylindrical portion 4 , and the outer end of the adjustment component is connected to the elastic shell 6 .

[0026] 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 with the side opening. The adjustment component can lift the middle part of the elastic shell 6 outward to increase the diameter of the side opening of the cylindrical part 4 and balance the retracted part 5.

[0027] 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 portion 4 and the gathering portion 5 are all located on the same straight line; The eccentricity direction between the first separation box 2 and the cylindrical portion 4 is opposite to the eccentricity direction between the second separation box 3 and the cylindrical portion 4 .

[0028] The axis of the first separation box 2 and the axis of the second separation box 3 are respectively arranged on both sides of the axis of the cylindrical portion 4 .

[0029] like Figure 4 and Figure 5 As shown, the height of the partition plate is less than the inner cavity height of the sedimentation box body 1, and the partition plates are respectively a first partition plate 7 arranged inside the first separation box 2, a second partition plate 8 arranged inside the second separation box 3, and a third partition plate 9 arranged inside the gathering portion 5; The first partition plate 7 separates the first separation box 2 into a first sedimentation area 10 and a first drainage area, the second partition plate 8 separates the second separation box 3 into a second sedimentation area 11 and a second drainage area, and the third partition plate 9 separates the gathering part 5 into a third sedimentation area 12 and a third drainage area. The bottom of the first sedimentation area 10, the bottom of the second sedimentation area 11 and the bottom of the third sedimentation area 12 are all connected to a sewage pipe 13.

[0030] A drain valve is provided on the drain pipe 13. With 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 is connected to the bottom surface of the first sedimentation area 10, and the second sedimentation area 11 and the third sedimentation area 12 have the same connection structure with the drain pipe 13. The opening width of the drain pipe 13 is not less than the upper end width of the drain pipe 13.

[0031] like Figure 4 As shown, an inclined telescopic rod is provided on the upper part of the sedimentation tank body 1, and the telescopic rod is connected to the upper part of the partition plate. When the telescopic rod is extended, the partition plate moves downwardly and contacts and seals with the bottom of the sedimentation tank body 1.

[0032] The telescopic rods include 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 ends of the telescopic rods are connected to the top of the sedimentation tank body 1.

[0033] like Figure 1 As shown, the adjustment assembly includes a plurality of telescopic cylinders 14 fixed to the top of the sedimentation box body 1, the length direction of the telescopic cylinders 14 is arranged along the diameter direction of the cylindrical portion 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, and the outer end of the connecting arm 15 is connected to the connecting sleeve 16.

[0034] The extended end of the telescopic cylinder 14 is located outside the sedimentation tank body 1, and the connecting arm 15 is vertically arranged outside 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 shell 6 to protrude outward.

[0035] like Figure 2 and Figure 4 As shown, a water inlet pipe 18 is connected to the top of the first separation box 2, and a drain pipe 19 is connected to the upper part of the cylindrical part 4.

[0036] like Figure 4 As shown, a first drain outlet is provided on the side of the first separation box 2 away from the first sedimentation area 10, and the first drain outlet is communicated with the interior of the second separation box 3. A second drain outlet is provided on the side of the second separation box 3 away from the second sedimentation area 11, and the second drain outlet is communicated with the interior of the sedimentation box body 1.

[0037] The wastewater is directly discharged into the upper part of the first separation box 2 through the water inlet pipe 18. After being centrifuged once in the first separation box 2, the relatively clear wastewater enters the second separation box 3 through the first drain port. The wastewater is subjected to secondary centrifugal separation in the second separation box 3. The wastewater with solid impurities separated is discharged into the sedimentation box body 1 through the second drain port for the third centrifugal separation.

[0038] A driving motor 17 is connected to the lower side of the sedimentation tank body 1 , and an output shaft of the driving motor 17 is connected to the axial direction of the cylindrical portion 4 .

[0039] During the centrifugation process, 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 portion 4 and the axis of the drive motor 17.

[0040] A circular guide bar can be provided at the bottom of the sedimentation box body 1, and the guide bar is provided coaxially with the driving motor 17. A guide rail is provided at the lower side of the sedimentation box body 1, and the guide bar is slidably connected with the guide rail to improve the stability of the device operation. At the same time, other supporting structures can also be provided outside the device, and the specific structure is preferably such that it does not affect the rotation of the sedimentation box body 1.

[0041] Directions: When the device is used, the driving motor 17 drives the sedimentation tank body 1 to rotate, so that the first separation tank 2, the second separation tank 3 and the sedimentation tank body 1 rotate simultaneously; During the centrifugal process, the telescopic cylinder 14 is shortened, so that the extended end of the telescopic cylinder 14 pulls the upper end of the connecting arm 15 to move toward the axial direction of the cylindrical portion 4, so that the lower end of the connecting arm 15 pulls the middle part of the elastic shell 6 outward, increasing the diameter of the cylindrical portion 4 away from the side of the gathering portion 5, playing the role of balancing the gathering portion 5; Wastewater is continuously discharged into the first separation box 2 through the water inlet pipe 18. The water inside the first separation box 2 enters the second separation box 3 through the first drain port after the first centrifugation. The water inside the second separation box 3 is discharged into the sedimentation box body 1 through the second drain port after the second centrifugation. The wastewater inside the sedimentation box is finally discharged to the outside through the drain pipe 19 after the third centrifugation, and the solid impurities are discharged downward through the sewage pipe 13, thereby realizing the solid-liquid separation of the wastewater.

[0042] In the above centrifugal process, the specific adjustment process of the partition plate is as follows: During the centrifugation process, since the solid impurities have a certain weight, they move to the side away from the axis direction of the driving motor 17 under the action of centrifugal force. The solid impurities inside the first separation box 2 enter the first sedimentation area 10 through the gap between the first partition plate 7 and the inner wall of the first separation box 2, and gather inside the first sedimentation area 10; The solid impurities in the second separation box 3 enter the second sedimentation area 11 through the gap between the second partition plate 8 and the inner wall of the second separation box 3, and are collected in the second sedimentation area 11; The solid impurities inside the sedimentation box body 1 enter into the gathering portion 5 under the action of centrifugal force, and enter into the third sedimentation area 12 through the gap between the third partition plate 9 and the inner wall of the gathering portion 5 .

[0043] After centrifugation for a period of time, the telescopic rod is extended, so that the first partition plate 7 contacts the side wall and the bottom of the first separation box 2, so that the first sedimentation area 10 is completely isolated from the lower middle part of the first drainage area; the second partition plate 8 contacts the side wall and the bottom of the second separation box 3, so that the second sedimentation area 11 is completely isolated from the lower middle part of the second drainage area; the third partition plate 9 contacts the inner wall and the bottom of the gathering part 5, so that the third sedimentation area 12 is completely isolated from the lower middle part of the third drainage area, and the drain valve of the drain pipe 13 is opened to discharge the solid impurities downward.

[0044] After the partition plate is lowered, the liquid level inside the device body 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.

[0045] The partition plate is operated at intervals by the telescopic rod. After the solid impurities are discharged, the telescopic rod is shortened to reset the partition plate, so that the centrifugal separation and discharge of the solid impurities are carried out simultaneously, thereby realizing the continuous treatment of glass fiber wastewater.

The patent protection scope of the present invention includes but is not limited to the product form and style of the above-mentioned specific embodiments.
