Description

[0002] The dyeing wastewater of cloth contains a large amount of harmful substances such as dyes, auxiliaries and heavy metals. If it is directly discharged into natural water without treatment, it will cause the color of the water to deepen and the transparency to decrease, affecting the survival environment of aquatic organisms and causing water pollution. For example, some dyes are toxic and can inhibit the photosynthesis of aquatic plants, causing the death of aquatic plants. At the same time, they can also poison aquatic animals such as fish and destroy the balance of the aquatic ecosystem.

[0003] When treating sewage, the sewage needs to be preliminarily treated to remove large-particle impurities, then coagulant is added to make the colloidal substances and suspended solids in the wastewater form flocculation bodies, and then the flocculation bodies are settled under the action of gravity.

[0024] Through the above technical scheme, when the preliminarily filtered sewage enters the inside of the flocculation bin 3, the coagulant is added into the inside of the material bin 61, then the coagulant enters the inside of the distribution cover 63 through the rotating pipe 62, when the coagulant is added, the output shaft of the motor 71 is rotated, the gears 72 on the output shaft of the motor 71 are rotated, the rotating pipe 62 is driven to rotate under the mutual meshing of the two gears 72, the coagulant is discharged from the multiple falling holes 64 under the action of the inclined arrangement of the inside of the distribution cover 63 and the cooperation of the distribution cover 63, the coagulant is uniformly added into the inside of the flocculation bin 3 under the cooperation of the rotation of the distribution cover 63, so that the coagulant is uniformly distributed in the sewage and rapidly mixed with the suspended matters in the sewage, thereby affecting the precipitation efficiency of the suspended matters and the efficiency of the dyeing sewage treatment.

[0025] When the coagulant is added, the rotating pipe 62 rotates with the distribution cover 63, so that the rotating drum 66 rotates with the stirring ring 67 and the stirring blade 68 arranged outside the rotating drum 66, which further accelerates the rapid mixing of the coagulant and the suspended matter in the sewage, thereby affecting the efficiency of the suspended matter precipitation and the efficiency of the dyeing sewage treatment.

[0026] The lifting assembly 8 is arranged below the distribution cover 63, and the lifting assembly 8 comprises a lifting frame 81 slidably connected to the outside of the rotating drum 66, the outside of the lifting frame 81 is rotationally connected to the inside of the stirring ring 67, a limiting portion 82 is arranged between the lifting frame 81 and the stirring ring 67, the lifting assembly 8 further comprises a screw sleeve 83 slidably connected to the inside of the rotating drum 66, the inside of the screw sleeve 83 is threadedly connected with a reciprocating screw rod 84, the bottom of the reciprocating screw rod 84 is fixedly connected to the inside bottom of the treatment box 1, and the outside of the screw sleeve 83 and the inside of the lifting frame 81 are fixedly connected with magnetic blocks 85.

[0027] By adopting the above technical scheme, when the rotating drum 66 rotates with the stirring ring 67 and the stirring blade 68 arranged outside the rotating drum 66, since the bottom of the reciprocating screw rod 84 is fixed to the treatment box 1, relative rotation is generated between the rotating drum 66 and the reciprocating screw rod 84 when the rotating drum 66 rotates, so that the screw sleeve 83 and the reciprocating screw rod 84 generate relative movement, which enables the screw sleeve 83 to reciprocate up and down, and under the action of the magnetic blocks 85, the lifting frame 81 moves up and down with the screw sleeve 83, and under the action of the rotating drum 66, the lifting frame 81, the stirring ring 67 and the stirring blade 68 rotate, so that the stirring blade 68 can move up and down when rotating, which facilitates stirring at different positions, thereby facilitating further acceleration of the rapid mixing of the coagulant and the suspended matter in the sewage, thereby affecting the efficiency of the suspended matter precipitation and the efficiency of the dyeing sewage treatment.

[0028] The limiting part 82 comprises a groove 821 opened on the ring side of the lifting frame 81, the inside of the groove 821 is rotationally connected with a limiting block 822, the torsion spring 823 is fixedly connected between the limiting block 822 and the lifting frame 81, the limiting part 82 further comprises a clamping block 824 fixedly connected inside the stirring ring 67, one side of the limiting block 822 is tightly attached to the inside of the groove 821, the top of the lifting frame 81 is provided with the adsorption pipe assembly 5, the adsorption pipe assembly 5 comprises the adsorption pipe 51 fixedly inserted into the top front end of the lifting frame 81, the bottom of the adsorption pipe 51 is inserted into the inside of the rotating drum 66 and enters the inside of the rotating pipe 62 through the middle part of the distribution cover 63, the bottom of the adsorption pipe 51 is fixedly inserted with the first bellows pipe 52, the top of the first bellows pipe 52 is fixedly inserted with the intermediate pipe 53, the top of the intermediate pipe 53 is fixedly installed with the rotary joint 54, the rotary joint 54 is a mature prior art, and its principle will not be described in detail, the bottom of the rotary joint 54 is slidably connected with the top of the rotating pipe 62 through a rod, so that the rotary joint 54 can move up and down.

[0029] The top of the rotary joint 54 is fixedly installed with the outer pipe 55, the bottom of the outer pipe 55 is fixedly inserted with the second bellows pipe 56, the bottom of the second bellows pipe 56 is fixedly inserted with the discharge pipe 57, the discharge pipe 57 extends into the inside of the decolorizing bin 4, the top rear end of the lifting frame 81 is fixedly inserted with the adsorption cover 13, the middle part of the adsorption pipe 51 is composed of a flexible pipeline, which does not affect the movement of the lifting frame 81, and a centrifugal pump needs to be installed in the inside of the discharge pipe 57, for conveying the flocculated clean water in the flocculation bin 3 into the inside of the decolorizing bin 4.

[0030] The inside of the treatment box 1 is provided with the electromagnet 11 on the left side of the stirring ring 67, one end of one of the stirring blades 68 is fixedly connected with an adsorption block, and 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 scheme, before the clean water in the upper layer is discharged, the output shaft of the motor 71 is first rotated in the opposite direction, at this time the electromagnet 11 is energized, under the action of the screw thread connection between the reciprocating screw rod 84 and the screw rod sleeve 83, the lifting frame 81 is adjusted to the top position.

[0032] Subsequently, the centrifugal pump needs to be started through the inside of the discharge pipe 57, so as to pass the clean water in the upper layer into the inside of the decolorizing bin 4 through the adsorption pipe assembly 5 by the action of the centrifugal pump.

[0033] Subsequently first through the motor 71 output shaft continue to rotate in the opposite direction with the stirring, under the action of the reciprocating screw rod 84 and the screw rod sleeve 83, can make the lifting frame 81 with the absorption cover 13 gradually down, so that the absorption cover 13 gradually on the upper layer of clean water absorption, so as to reduce the discharge of upper layer of clean water, and then avoid the disturbance to the clean water when the lifting frame 81 gradually down, so as to avoid 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 cover 13, and then enters the inside of the decolorizing bin 4 in turn through the absorption pipe 51, the first corrugated pipe 52, the intermediate pipe 53, the rotary joint 54, the external pipe 55, the second corrugated pipe 56 and the discharge pipe 57.

[0035] When stirring, the rotating drum 66 and the lifting frame 81 rotate clockwise around the Figure 9 At this time, the limiting block 822 cannot be deflected under the limiting action of the groove 821, and under the extrusion of the limiting block 822 to the clamping block 824, the stirring ring 67 and the stirring blade 68 can be rotated for stirring.

[0036] When discharging the upper layer of clean water, the rotating drum 66 and the lifting frame 81 rotate counterclockwise around the Figure 9 At this time, when the limiting block 822 approaches the clamping block 824, the limiting block 822 can be deflected because the adsorption force of the electromagnet 11 to the adsorption block is greater than the elastic force of the torsion spring 823, so that the stirring ring 67 and the stirring blade 68 will not rotate with the lifting frame 81, so that the water will not be disturbed when discharging the upper layer of clean water, and further avoiding the disturbance to the clean water when the lifting frame 81 gradually down, so as to avoid affecting the effect of sewage treatment.

[0037] Embodiment two: the technical scheme of this embodiment is different from that of embodiment one, which comprises: Figures 1 to 4 The top of the treatment box 1 is provided with an even falling assembly 9, the even falling assembly 9 comprises a blocking block 91 fixedly connected to the outer wall of the intermediate pipe 53, the blocking block 91 and the rotating pipe 62 are fixedly connected with a first spring 92, the even falling assembly 9 further comprises a lifting frame 93 fixedly connected to the outer wall of the external pipe 55, the bottom of the lifting frame 93 is inclinedly arranged at the front and rear ends, the outer wall of the rotating pipe 62 is fixedly connected with a bending frame 94 at the top, the top of the bending frame 94 is rotatably connected with a rotating bead 95, the outer wall of the rotating pipe 62 is fixedly connected with a stirring plate 12 at the inside of the bin 61, and a certain amount of coagulant is added in the bin 61 each time.

[0038] By adopting the above technical scheme, when the coagulant is added and stirring is performed, when the rotating pipe 62 rotates to close to the lifting frame 93 with the bent frame 94, under the extrusion 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 blocking block 91 moves upward and does not block the empty slot 65, so that the coagulant can gradually enter the inside of the distribution cover 63 and be discharged, thereby facilitating uniform distribution of the coagulant.

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

[0040] A dyeing waste liquid treatment method, comprising the following steps: S1, primary filtration, a filter plate is fixed in the inside of the primary filtration bin 2, for primary filtration of impurities in sewage; S2, flocculation, a coagulant is added in the flocculation bin 3, for precipitation of suspended solids, a decolorizing agent or an oxidizing agent is added in the decolorization bin 4 for decolorization treatment of dyeing wastewater.

[0041] Working principle: when the primary filtered sewage enters the inside of the flocculation bin 3, a coagulant is added in the inside of the material bin 61, then the coagulant enters the inside of the distribution cover 63 through the rotating pipe 62, when the coagulant is added, the motor 71 is rotated through the output shaft, the gear 72 on the output shaft of the motor 71 is rotated, under the mutual meshing action between the two gears 72, the rotating pipe 62 can be rotated with the distribution cover 63, and under the action of the inclined arrangement in the inside of the distribution cover 63, the coagulant can be discharged from the plurality of falling holes 64, under the rotation of the distribution cover 63, the coagulant can be uniformly added in the inside of the flocculation bin 3, thereby facilitating uniform distribution of the coagulant in the sewage, facilitating rapid mixing of the coagulant with the suspended solids in the sewage, thereby affecting the efficiency of the suspended solids precipitation, and further affecting the efficiency of the dyeing wastewater treatment, while the coagulant is added, the rotating pipe 62 can be rotated with the distribution cover 63, so that the rotating drum 66 can be rotated with the stirring ring 67 and the stirring blade 68 arranged outside the rotating drum 66, so that the coagulant can be further rapidly mixed with the suspended solids in the sewage, thereby affecting the efficiency of the suspended solids precipitation, and further affecting the efficiency of the dyeing wastewater treatment 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.
