[0002] Sulfur black is a commonly used dye, mainly used for dyeing cotton fibers and other cellulose fibers, especially denim and other wear-resistant fabrics. The wastewater generated by sulphur black dye during the dyeing process contains unreacted dyes and other chemicals, and special treatment and recovery equipment is required to achieve the degradation of harmful substances in the wastewater and resource recovery.

[0003] When treating black sulfide wastewater, it needs to go through the following treatment steps, including dissolution, oxidation, filtration, neutralization, etc., so that valuable by-products such as sodium thiosulfate can be recovered, and by-products such as sodium chloride solution can also be obtained, thereby achieving the purpose of turning waste into treasure. However, the existing recovery device can only perform single-step treatment, the treatment efficiency is low, and the recovery treatment effect is not good.

[0004] To this end, we propose a sulphur black dye liquor recovery device that can perform multi-step treatment to ensure recycling. Utility Model Content

After dissolution, the chemical solvent is introduced into the treatment box through the drug inlet pipe to oxidize the sulfide black wastewater, and the reducing sulfide in the sulfide black wastewater is converted into a form that is easy to handle.

DETAILED DESCRIPTION

[0018] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0019] Example 1

[0020] A sulphur black dye liquor recovery device, such as Figure 1-3As shown, it includes a sedimentation box 1, a treatment box 2, universal wheels 3, a feed pipe 4, a drug feed pipe 5, a motor 6, a water outlet pipe 7, a stirrer 8, a water baffle 9, a first filter plate 10, a charging basket 11 and a second filter plate 12. The upper side of the sedimentation box 1 is connected to the treatment box 2, and four universal wheels 3 are fixedly connected to the bottom side of the sedimentation box 1. The upper left part of the treatment box 2 is connected to the feed pipe 4, the upper right part of the treatment box 2 is connected to the drug feed pipe 5, the middle part of the upper side of the treatment box 2 is fixedly connected, the front right part of the sedimentation box 1 is connected to the water outlet pipe 7, and the output shaft of the motor 6 is fixedly connected to Agitator 8, agitator 8 extends into the treatment box 2, a water-blocking plate 9 is slidably connected to the middle of the treatment box 2, a first filter plate 10 is fixedly connected to the lower part of the treatment box 2, a loading basket 11 is fixedly connected to the upper front part of the sedimentation box 1, the first filter plate 10 is inclined to facilitate the filtered solids to enter the loading basket 11, the bottom of the loading basket 11 is inclined and fixedly connected to a filter screen, the loading basket 11 is connected to the sedimentation box 1, a second filter plate 12 is slidably connected to the upper part of the sedimentation box 1, and handles are fixedly connected to the left side of the second filter plate 12 and the water-blocking plate 9.

[0021] like Figure 1-3 As shown, a valve 17 is also included, and the valve 17 is fixedly connected to the water outlet pipe 7.

[0022] When using the device, under the action of the universal wheel 3, the device can move freely, and the staff introduces the sulfide black wastewater into the treatment box 2 through the feed pipe 4. At this time, the sulfide black wastewater is blocked by the baffle plate 9 at the upper part of the treatment box 2, and the motor 6 drives the agitator 8 to rotate to mix and dissolve the sulfide black wastewater, ensuring that the pollutants in the wastewater are fully dispersed, which is convenient for subsequent treatment operations. After the dissolution is completed, the chemical solvent is introduced into the treatment box 2 through the drug feed pipe 5 to oxidize the sulfide black wastewater. The reduced sulfide in the sulfide black wastewater is converted into a form that is easy to handle through oxidation. After the oxidation is completed, the staff controls the baffle plate 9 to slide to the left and open. At this time, the oxidized sulfide black wastewater will flow downward, first passing through the first filter plate 10 for preliminary filtration, and the first filter plate 10 filters out The suspended matter and colloidal particles will move forward and enter the loading basket 11, and the liquid entering the loading basket 11 will enter the sedimentation tank 1 after secondary filtration through the filter screen. The initially filtered black sulfide wastewater continues to flow downward and then passes through the second filter plate 12 for secondary filtration. The black sulfide wastewater after secondary filtration will also enter the sedimentation tank 1. The black sulfide wastewater entering the sedimentation tank 1 can be precipitated and neutralized to adjust the pH value of the wastewater to an appropriate range. At the same time, the second filter plate 12 can also be slid and pulled out to the left to clean up the filtered suspended matter and colloidal particles. After the precipitation is neutralized, the staff can open the valve 17 to discharge the wastewater through the outlet pipe 7. The device can perform dissolution, oxidation, filtration, neutralization and other steps in sequence without replacing the processing and recovery equipment, which can improve the efficiency and effect of processing and recovery.

[0024] On the basis of Example 1, Figure 1 and Figure 3 As shown, it also includes a suction pipe 13, a suction pump 14, a discharge pipe 15 and a fixing frame 16. The fixing frame 16 is fixedly connected to the right side of the sedimentation tank 1, and the suction pump 14 is fixedly connected to the fixing frame 16. The suction pump 14 is connected to the suction pipe 13, and the suction pipe 13 extends into the bottom of the sedimentation tank 1. The discharge pipe 15 is connected to the suction pump 14.

[0025] When wastewater is precipitated, sediment will accumulate at the bottom of the sedimentation tank 1. The staff can control the operation of the suction pump 14 to extract the sediment at the bottom of the sedimentation tank 1 through the suction pipe 13, and the extracted sediment is then discharged through the discharge pipe 15, thereby further reducing pollutants in the wastewater and improving the wastewater treatment effect.

[0026] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
