Description

Technical Field

[0001] This utility model relates to the technical field of wastewater treatment, specifically to an ozone oxidation device for treating dyeing and printing wastewater. Background Technology

[0002] Wastewater discharged from dyeing and finishing mills, wool dyeing and finishing plants, and silk factories that primarily process cotton, linen, chemical fibers and their blends, as well as silk, varies in volume and quality depending on the fiber type and processing technology. Dyeing and finishing plants typically generate large volumes of wastewater, consuming 100-200 tons of water per ton of textiles processed, with 80%-90% of this being discharged as wastewater. Dyeing and finishing wastewater is characterized by its large volume, high organic pollutant content, high alkalinity, and significant quality fluctuations, making it one of the most difficult types of industrial wastewater to treat. It contains dyes, sizing agents, auxiliaries, oils, acids and alkalis, fiber impurities, sand, and inorganic salts.

[0003] Typically, ozone oxidation is used in the treatment of this type of wastewater. An existing ozone oxidation wastewater treatment device, such as the one with patent publication number CN215855313U, can effectively improve ozone utilization. Compared with existing ozone oxidation devices, it can increase ozone oxidation efficiency by more than 50%, thereby improving wastewater treatment efficiency. Under the same water quality conditions, it can save and reduce unit energy consumption by more than 50%, thus effectively reducing the cost of wastewater treatment.

[0004] However, the device does not mix ozone and wastewater sufficiently, resulting in low treatment efficiency and poor practicality. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides an ozone oxidation treatment device for dyeing and printing wastewater, which has the following beneficial effects:

[0015] Ozone is generated by the ozone generator.

This draws the ozone into the collection cylinder through the input head. Then, wastewater is fed into the sewage treatment tank through the inlet pipe. During this process, the reciprocating motor reverses, causing the piston to press down and expelling the ozone through the output head back into the inlet pipe. The ozone mixes thoroughly with the wastewater before being discharged into the sewage treatment tank for further treatment. After completion, the on / off valve opens, and the treated wastewater is discharged through the drain pipe. The method of extruding ozone through the inlet pipe facilitates flow control, ensures uniform internal mixing, and improves practicality. Attached Figure Description

[0022] Example

[0023] Please see Figure 1-4An ozone oxidation treatment device for dyeing and printing wastewater includes a wastewater treatment tank 1, an inlet pipe 2, a drain pipe 3, and an on / off valve 4. The input end of the wastewater treatment tank 1 is connected to the inside of the inlet pipe 2, and the output end of the wastewater treatment tank 1 is connected to the inside of the drain pipe 3. The drain pipe 3 is equipped with the on / off valve 4. The device also includes an output head 5, an ozone collection cylinder 6, a piston 7, a top frame 8, a reciprocating motor 9, a threaded rod 10, a threaded pipe 11, an input head 12, an ozone generator 13, and a connecting frame 21. The upper front part of the wastewater treatment tank 1 is connected to the rear side of the ozone collection cylinder 6 via the connecting frame 21. The output end of the ozone collection cylinder 6 is connected to one side of the inside of the inlet pipe 2 via the output head 5. The ozone generator 13 is located on the right front part of the wastewater treatment tank 1. The input end of the ozone collection cylinder 6 is connected to the output end of the ozone generator 13 via the input head 12. The inside of the ozone collection cylinder 6 is slidably connected to the outside of the piston 7. The top center of piston 7 is connected to the bottom of threaded tube 11, the top center of top frame 8 is connected to the bottom of reciprocating motor 9, the output end of reciprocating motor 9 is connected to the top of threaded rod 10, and the outer wall of threaded rod 10 is screwed to the inner wall of threaded tube 11. Ozone is generated by the operation of ozone generator 13, and the operation of reciprocating motor 9 causes threaded rod 10 to rotate. Threaded rod 10, through screwing with threaded tube 11, drives piston 7 to rise, creating negative pressure inside ozone collection cylinder 6. Ozone is drawn into ozone collection cylinder 6 through input head 12, and then wastewater is input into sewage treatment tank 1 through water inlet pipe 2. During this process, reciprocating motor 9 reverses its operation, causing piston 7 to press down and ozone to be discharged through output head 5 into water inlet pipe 2. It mixes thoroughly with the wastewater flow and is then discharged into sewage treatment tank 1 for further treatment. After completion, the on / off valve 4 is opened, and the treated wastewater is discharged through drain pipe 3.

[0024] It also includes a one-way valve 14. A set of one-way valves 14 is provided on the input head 12 and the output head 5 respectively. The one-way valve 14 corresponds to the output direction of the output head 5 and the input direction of the input head 12. The one-way valve 14 can enable one-way conduction of the output of the output head 5 and the input of the input head 12, avoid backflow and improve reliability.

[0025] It also includes an oil injection nozzle 15, with the upper front part of the threaded tube 11 connected to the inner side of the oil injection nozzle 15; oil can be injected into the inner wall of the threaded tube 11 through the oil injection nozzle 15 for convenient lubrication and maintenance.

[0026] It also includes an oil filling cap 16, and the outer side of the oil filling nozzle 15 and the inner side of the oil filling cap 16 can be detachably installed; after the oil filling cap 16 is installed on the outer side of the oil filling nozzle 15, the inside of the oil filling nozzle 15 can be sealed and protected, improving reliability.

[0027] It also includes a stirring drive motor 17, a reducer 18, a stirring rod 19, and movable blades 20. The middle right side of the wastewater treatment tank 1 is connected to the inner side of the reducer 18. The input end of the reducer 18 is connected to the output end of the stirring drive motor 17, and the output end of the reducer 18 is connected to the right side of the stirring rod 19. The stirring rod 19 is rotatably installed inside the wastewater treatment tank 1, and multiple sets of movable blades 20 are evenly connected to the outer side of the stirring rod 19. When the stirring drive motor 17 is running, the reducer 18 can reduce the speed, causing the stirring rod 19 to rotate, which drives the multiple sets of movable blades 20 to act on the wastewater to stir, making the ozone mixing reaction inside more complete and improving the treatment efficiency.

[0028] In summary, when the ozone oxidation treatment device for dyeing and printing wastewater is in use, ozone is generated by the ozone generator 13. The reciprocating motor 9 operates, causing the threaded rod 10 to rotate. The threaded rod 10, through its screw-fitted engagement with the threaded pipe 11, drives the piston 7 to rise, creating a negative pressure inside the ozone collection cylinder 6. This negative pressure is then unidirectionally opened by the one-way valve 14, drawing the ozone into the ozone collection cylinder 6 through the input head 12. Subsequently, wastewater is fed into the sewage treatment tank 1 through the inlet pipe 2. During this process, the reciprocating motor 9 reverses its rotation, causing the piston 7 to press down, discharging the ozone through the output head 5 back into the inlet pipe 2. After being thoroughly mixed with the wastewater flow, the wastewater is discharged into the sewage treatment tank 1 for further treatment. The stirring drive motor 17 runs, which can be reduced by the reducer 18 to make the stirring rod 19 rotate, driving multiple sets of moving blades 20 to act on the wastewater to stir it, making the ozone mixing reaction inside more complete. After completion, the on / off valve 4 is opened, and the treated wastewater is discharged through the drain pipe 3. In addition, oil can be injected into the inner wall of the threaded pipe 11 through the oil injection nozzle 15 for convenient lubrication and maintenance. After the oil injection cap 16 is installed on the outside of the oil injection nozzle 15, the inside of the oil injection nozzle 15 can be sealed and protected to improve reliability.

[0029] The reciprocating motor 9, ozone generator 13, one-way valve 14, stirring drive motor 17, and reducer 18 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not elaborate further on them here.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
