Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a device and method for treating dyeing wastewater from electrostatically dyed fabrics. Background Technology

[0002] Fabric dyeing wastewater contains a large amount of harmful substances such as dyes, auxiliaries, and heavy metals. If it is discharged directly into natural water bodies without treatment, it will cause the water to darken in color and reduce its transparency, affecting the living environment of aquatic organisms and causing water pollution. For example, some dyes are toxic and can inhibit the photosynthesis of aquatic plants, leading to their death. At the same time, they can also poison fish and other aquatic animals, disrupting the balance of the aquatic ecosystem.

[0003] When treating wastewater, it is necessary to first perform preliminary treatment to remove large particulate impurities. Then, coagulants are added to form flocs from the colloidal substances and suspended solids in the wastewater. These flocs then settle under gravity. After separating the sediment, decolorizing agents or oxidants can be used to treat the high color of the dyeing wastewater, thus achieving the treatment of fabric dyeing wastewater.

[0004] For example, the "A Wastewater Treatment Equipment for Textile Dyeing" with publication number "CN119977240A" effectively improves the filtration effect of the filter conveyor belt by using a scraping mechanism and a deep cleaning mechanism to deeply clean the filter conveyor belt that enters the cleaning box.

[0005] Adding coagulants to dyeing wastewater to form flocs and allow them to settle is an important step in dyeing wastewater treatment. However, when adding coagulants, it is difficult for them to mix quickly with the suspended solids in the wastewater, which affects the efficiency of suspended solids sedimentation and thus the efficiency of dyeing wastewater treatment. Summary of the Invention

[0006] The purpose of this invention is to provide a dyeing wastewater treatment device for electrostatically dyed fabrics, which allows the coagulant to be uniformly added into the flocculation chamber, thereby facilitating the uniform distribution of the coagulant in the wastewater and enabling the coagulant to quickly mix with the suspended solids in the wastewater, thus affecting the efficiency of suspended solids sedimentation and consequently the efficiency of dyeing wastewater treatment, in order to solve the problems mentioned in the background art.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1 to 10The present invention provides a technical solution: a dyeing wastewater treatment device for electrostatic dyeing fabrics, comprising a treatment tank 1, wherein the interior of the treatment tank 1 is arranged from left to right as a primary filtration chamber 2, a flocculation chamber 3, and a decolorization chamber 4. The primary filtration chamber 2 is fixed with a filter plate for preliminary filtration of impurities in the wastewater. A coagulant is added to the flocculation chamber 3 for settling suspended solids. A decolorizing agent or oxidant is added to the decolorization chamber 4 for decolorizing the dyeing wastewater.

[0023] An inlet pipe 10 is provided between the primary filtration chamber 2 and the flocculation chamber 3. A liquid pump is installed at the bottom of the inlet pipe 10 to allow water initially filtered from the primary filtration chamber 2 to enter the interior of the flocculation chamber 3 through the inlet pipe 10. The waste liquid treatment device also includes an additive component 6 located at the top of the flocculation chamber 3. The additive component 6 is used to add flocculant into the interior of the flocculation chamber 3. The additive component 6 includes a hopper 61 located at the middle of the top of the treatment tank 1. A rotating pipe 62 is rotatably connected to the middle part of the hopper 61. A distribution hood 63 is fixedly inserted into the bottom of the rotating pipe 62. The interior of the distribution hood 63 is inclined. The bottom of the distribution hood 63... A drop hole 64 is provided. A slot 65 is provided on the outer wall of the rotating tube 62 near the bottom of the hopper 61. A rotating cylinder 66 is fixedly connected to the bottom of the distribution cover 63. An agitator ring 67 is arranged on the outside of the rotating cylinder 66. An agitator blade 68 is fixedly connected to the ring side of the agitator ring 67. The waste liquid treatment device also includes a drive assembly 7 disposed on the top of the hopper 61. The drive assembly 7 is used to drive the rotating tube 62 to rotate. The drive assembly 7 includes a motor 71 fixedly connected to the top of the hopper 61. Gears 72 are fixedly connected to the output shaft of the motor 71 and the top of the outer wall of the rotating tube 62. The two gears 72 mesh with each other.

[0024] By adopting the above technical solution, when the pre-filtered wastewater enters the flocculation chamber 3, coagulant is added into the hopper 61. The coagulant then enters the distribution hood 63 through the rotating pipe 62. When adding coagulant, the output shaft of the motor 71 rotates, causing the gear 72 on the output shaft of the motor 71 to rotate. Under the action of the meshing between the two gears 72, the rotating pipe 62 carries the distribution hood 63. With the inclined setting of the distribution hood 63, the coagulant can be discharged from multiple drop holes 64. With the rotation of the distribution hood 63, the coagulant can be evenly added into the flocculation chamber 3, which facilitates the uniform distribution of the coagulant in the wastewater and facilitates the rapid mixing of the coagulant with the suspended solids in the wastewater, thereby affecting the efficiency of suspended solids sedimentation and thus affecting the efficiency of dyeing wastewater treatment.

[0025] While adding coagulant, the rotating pipe 62 rotates along with the distribution hood 63, which in turn causes the rotating drum 66 to rotate along with the external stirring ring 67 and stirring blades 68. This further accelerates the mixing of the coagulant with the suspended solids in the wastewater, thereby affecting the efficiency of suspended solids sedimentation and consequently the efficiency of dyeing wastewater treatment.

[0026] Below the material distribution cover 63 is a lifting assembly 8. The lifting assembly 8 includes a lifting frame 81 that is slidably connected to the outside of the rotating drum 66. The outside of the lifting frame 81 is rotatably connected to the inside of the stirring ring 67. A limiting part 82 is provided between the lifting frame 81 and the stirring ring 67. The lifting assembly 8 also includes a lead screw sleeve 83 that is slidably connected to the inside of the rotating drum 66. A reciprocating lead screw 84 is threadedly connected to the inside of the lead screw sleeve 83. The bottom of the reciprocating lead screw 84 is fixedly connected to the bottom of the inner side of the processing box 1. Magnetic blocks 85 are fixedly connected to both the outside of the lead screw sleeve 83 and the inside of the lifting frame 81.

[0027] By adopting the above technical solution, when the rotating drum 66 rotates with its externally mounted stirring ring 67 and stirring blades 68, since the bottom of the reciprocating screw 84 is fixed to the treatment box 1, a relative rotation occurs between the rotating drum 66 and the reciprocating screw 84 when the rotating drum 66 rotates. This causes the screw sleeve 83 to move relative to the reciprocating screw 84, allowing the screw sleeve 83 to move up and down. Under the action of the magnetic block 85, the lifting frame 81 can move up and down with the screw sleeve 83. At the same time, under the action of the rotating drum 66, the lifting frame 81, stirring ring 67, and stirring blades 68 rotate. This allows the stirring blades 68 to move up and down when rotating, facilitating stirring at different positions. This is beneficial for further accelerating the mixing of coagulant and suspended solids in wastewater, thereby affecting the efficiency of suspended solids sedimentation and ultimately affecting the efficiency of dyeing wastewater treatment.

[0028] The limiting part 82 includes a groove 821 formed on the ring side of the lifting frame 81. A limiting block 822 is rotatably connected inside the groove 821. A torsion spring 823 is fixedly connected between the limiting block 822 and the lifting frame 81. The limiting part 82 also includes a locking block 824 fixedly connected inside the stirring ring 67. One side of the limiting block 822 is close to the inside of the groove 821. An adsorption tube assembly 5 is provided on the top of the lifting frame 81. The adsorption tube assembly 5 includes an absorption tube 51 fixedly inserted into the front end of the top of the lifting frame 81. The bottom of the absorption tube 51 is inserted into the inside of the rotating drum 66 and enters the inside of the rotating tube 62 through the middle part of the distributing cover 63. A first corrugated pipe 52 is fixedly inserted into the bottom of the absorption tube 51. An intermediate pipe 53 is fixedly inserted into the top of the first corrugated pipe 52. A rotary joint 54 is fixedly installed on the top of the intermediate pipe 53. The rotary joint 54 is a mature existing technology, and its principle will not be described in detail. The bottom of the rotary joint 54 is slidably connected to the top of the rotating tube 62 through a rod, so that the rotary joint 54 can move up and down.

[0029] An external pipe 55 is fixedly installed on the top of the rotary joint 54. A second corrugated pipe 56 is fixedly inserted into the bottom of the external pipe 55. A discharge pipe 57 is fixedly inserted into the bottom of the second corrugated pipe 56. The discharge pipe 57 extends into the interior of the decolorization chamber 4. An absorption cover 13 is fixedly inserted into the top rear end of the lifting frame 81. The middle part of the absorption pipe 51 is composed of a flexible pipe that does not affect the movement of the lifting frame 81. A centrifugal pump needs to be installed inside the discharge pipe 57 to transport the flocculated clean water in the flocculation chamber 3 to the interior of the decolorization chamber 4.

[0030] An electromagnet 11 is located inside the processing chamber 1 to the left of the stirring ring 67. An adsorption block is fixedly connected to the end of one of the stirring blades 68. The adsorption force of the electromagnet 11 on the adsorption block is greater than the elastic force of the torsion spring 823.

[0031] By adopting the above technical solution, after flocculation is completed and before the upper layer of clear water needs to be discharged, the output shaft of the motor 71 is rotated in the opposite direction to the previous one. At this time, the electromagnet 11 is energized, and under the action of the reciprocating screw 84 and the screw sleeve 83 threaded connection, the lifting frame 81 is adjusted to the top position.

[0032] Subsequently, a centrifugal pump needs to be installed inside the discharge pipe 57 to start, so that the upper layer of clean water can be passed into the decolorization chamber 4 through the adsorption pipe assembly 5 by the action of the centrifugal pump.

[0033] Then, the output shaft of motor 71 continues to rotate in the opposite direction to the stirring. Under the action of reciprocating screw 84 and screw sleeve 83, the lifting frame 81 with the absorption hood 13 can gradually descend, so that the absorption hood 13 gradually absorbs the upper layer of clean water. This can reduce the discharge of the upper layer of clean water and avoid disturbing the clean water when the lifting frame 81 gradually descends, thereby avoiding affecting the effect of sewage treatment.

[0034] When absorbing the upper layer of clean water, the clean water enters the lifting frame 81 from the absorption hood 13, and then enters the interior of the decolorization chamber 4 through the absorption pipe 51, the first corrugated pipe 52, the intermediate pipe 53, the rotary joint 54, the outer pipe 55, the second corrugated pipe 56 and the discharge pipe 57 in sequence.

[0035] During stirring, the rotating drum 66 and the lifting frame 81 rotate around the attached... Figure 9 When rotated clockwise, the limiting block 822 is unable to deflect under the limiting action of the groove 821. Under the squeezing action of the limiting block 822 on the locking block 824, the stirring ring 67 and the stirring blade 68 can rotate to stir.

[0036] When the upper layer of clear water is discharged, the rotating drum 66 and the lifting frame 81 rotate around the attached... Figure 9 When the limiting block 822 approaches the locking block 824, the limiting block 822 can deflect because the attraction force of the electromagnet 11 on the adsorption block is greater than the elastic force of the torsion spring 823. This prevents the stirring ring 67 and the stirring blade 68 from rotating with the lifting frame 81, thus avoiding disturbance to the water when the upper layer of clear water is discharged. This further prevents disturbance to the clear water when the lifting frame 81 gradually descends, thereby avoiding affecting the effect of sewage treatment.

[0037] Example 2: The technical solution of this example differs from that of Example 1 in that: Figures 1 to 4 The top of the processing box 1 is equipped with a uniform dropping component 9. The uniform dropping component 9 includes a sealing block 91 fixedly connected to the outer wall of the intermediate pipe 53. A first spring 92 is fixedly connected between the sealing block 91 and the rotating pipe 62. The uniform dropping component 9 also includes a lifting frame 93 fixedly connected to the outer wall of the outer pipe 55. The bottom front and rear ends of the lifting frame 93 are inclined. A bending frame 94 is fixedly connected to the top of the outer wall of the rotating pipe 62. A rotating bead 95 is rotatably connected to the top of the bending frame 94. An agitator 12 is fixedly connected to the outer wall of the rotating pipe 62 inside the hopper 61. A certain amount of coagulant is added into the hopper 61 each time.

[0038] By adopting the above technical solution, when coagulant is added and stirred, when the rotating pipe 62 rotates and brings the bending frame 94 close to the lifting frame 93, under the squeezing action of the rotating bead 95, the lifting frame 93 can move upward with the outer pipe 55, the rotary joint 54 and the intermediate pipe 53. At this time, the sealing block 91 moves upward without sealing the empty trough 65, which facilitates the coagulant to gradually enter the interior of the distribution hood 63 and be discharged, thereby facilitating the uniform distribution of the coagulant.

[0039] When the rotating tube 62 rotates away from the lifting frame 93 along with the bending frame 94, the outer tube 55, the rotary joint 54 and the intermediate tube 53 move downwards to reset under the elastic force of the first spring 92.

[0040] A method for treating dyeing waste liquid includes the following steps: S1, Primary filtration: The primary filtration chamber 2 is equipped with a filter plate, which is used to initially filter impurities in the wastewater. S2, flocculation: Coagulant is added to flocculation chamber 3 to settle suspended solids. Decolorization chamber 4 is added to decolorize or oxidize the dyeing wastewater.

[0041] Working Principle: When the pre-filtered wastewater enters the flocculation chamber 3, coagulant is added into the hopper 61. The coagulant then enters the distribution hood 63 through the rotating pipe 62. During coagulant addition, the output shaft of the motor 71 rotates, causing the gear 72 on the output shaft to rotate. The meshing of the two gears 72 causes the rotating pipe 62 to pull the distribution hood 63 along with the inclined design of the distribution hood 63, allowing the coagulant to be discharged from multiple drop holes 64. Combined with the rotation of the distribution hood 63, this allows the coagulant to be discharged from multiple drop holes 64. This allows the coagulant to be evenly added into the flocculation chamber 3, facilitating its uniform distribution in the wastewater and rapid mixing with suspended solids. This process improves the efficiency of suspended solids sedimentation and consequently, the treatment efficiency of dyeing wastewater. Simultaneously, the rotation of the rotating pipe 62, along with the distribution hood 63, causes the rotating drum 66, along with its external stirring ring 67 and stirring blades 68, to rotate. This further accelerates the mixing of the coagulant with suspended solids in the wastewater, further impacting sedimentation efficiency and ultimately affecting the treatment efficiency of dyeing wastewater. Since the bottom of the reciprocating screw 84 is fixed to the treatment box 1, when the rotating drum 66 rotates, there is a relative rotation between the rotating drum 66 and the reciprocating screw 84, which causes the screw sleeve 83 to move relative to the reciprocating screw 84. This allows the screw sleeve 83 to move up and down. Under the action of the magnetic block 85, the lifting frame 81 can move up and down with the screw sleeve 83. At the same time, under the action of the rotating drum 66, the lifting frame 81, the stirring ring 67, and the stirring blade 68 rotate. This allows the stirring blade 68 to move up and down when it rotates, which is convenient for stirring at different positions. This helps to further accelerate the mixing of coagulant and suspended solids in wastewater, thereby affecting the efficiency of suspended solids sedimentation and thus affecting the efficiency of dyeing wastewater treatment.

[0042] First, the output shaft of motor 71 continues to rotate in the opposite direction to the stirring. Under the action of reciprocating screw 84 and screw sleeve 83, the lifting frame 81, carrying the absorption hood 13, gradually descends. The absorption hood 13 then gradually absorbs the upper layer of clean water. This reduces disturbance to the clean water during the discharge of the upper layer, thus avoiding affecting the wastewater treatment effect. When the upper layer of clean water is discharged, the rotating drum 66 and the lifting frame 81 rotate around the... Figure 9 When the limiting block 822 approaches the locking block 824, the limiting block 822 can deflect because the attraction force of the electromagnet 11 on the adsorption block is greater than the elastic force of the torsion spring 823. This prevents the stirring ring 67 and the stirring blade 68 from rotating with the lifting frame 81, thus avoiding disturbance to the water when the upper layer of clear water is discharged. This further prevents disturbance to the clear water when the lifting frame 81 gradually descends, thereby avoiding affecting the effect of sewage treatment.

[0043] When adding coagulant and stirring, when the rotating pipe 62 rotates and brings the bending frame 94 close to the lifting frame 93, under the squeezing action of the rotating bead 95, the lifting frame 93 can move upward with the outer pipe 55, the rotary joint 54 and the intermediate pipe 53. At this time, the sealing block 91 moves upward without sealing the empty trough 65, which facilitates the coagulant to gradually enter the interior of the distribution hood 63 and be discharged, thereby facilitating the uniform distribution of the coagulant.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
