Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a dyeing and finishing wastewater treatment device. Background Technology

[0002] Dyeing and finishing refers to the process of chemically treating textile materials, and is also commonly known as printing and dyeing in modern times. The dyeing and finishing process generates a large amount of wastewater, and direct discharge of wastewater will cause great damage to the environment. Therefore, wastewater treatment is necessary. Some devices have appeared in the existing technology, such as the dyeing and finishing wastewater treatment device described in announcement number CN219950782U, which includes a treatment tank. The treatment tank is equipped with an interconnected coagulation reaction zone and a sedimentation zone. A filter cylinder is rotatably connected to the top of the inner cavity of the coagulation reaction zone. One end of the filter cylinder passes through the top of the treatment tank and is rotatably connected to an inlet pipe. A stirring rod is provided on the side wall of the filter cylinder. In this utility model, the coagulation reaction zone and sedimentation zone are set in the treatment tank so that the wastewater can first undergo a coagulation reaction and then be precipitated in the sedimentation zone.

[0003] Although the above-mentioned equipment can mix flocculants and wastewater, the stirring direction is always the same during mixing. The regular movement of the wastewater will generate vortices, which will not make the wastewater turbulent, resulting in unsatisfactory mixing efficiency and further affecting the wastewater treatment efficiency.

[0004] The purpose of this invention is to provide a dyeing and finishing wastewater treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0014] The mounting sleeve, the annular corrugated plate, and the connecting frame rotate synchronously. The stirring protrusions on the connecting frame mix the wastewater, and the annular corrugated plate applies an upward force to the rotating roller when it rotates. Under the elastic force of the spring, the vertical rod always tends to move downward, causing the vertical rod to shake up and down, further cooperating with the stirring blades to make the wastewater turbulent, optimizing the mixing effect of the device and improving the wastewater treatment efficiency.

[0015] When the inclined tube needs to be replaced, start the hydraulic cylinder. The output end of the hydraulic cylinder pushes the moving seat to move. At this time, the inclined tube can be manually pulled out along the moving seat for replacement. Attached Figure Description

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

A bearing is embedded in the bearing seat 201. A screen cylinder 3 is fixedly connected to the inner ring of the bearing. An auger shaft 4 is fixedly connected to the bottom surface of the mixing tank 1. A sedimentation tank 6 is fixedly connected to one side of the mixing tank 1. A mixing module 5 is nested on the outer surface of the screen cylinder 3. The mixing module 5 is used for mixing coagulant and wastewater. A sedimentation module 7 is movably connected inside the sedimentation tank 6. The sedimentation module 7 is used for sedimentation of wastewater. The auger shaft 4 contacts the inner wall of the screen cylinder 3, so that solid impurities can rise along the auger shaft 4 when the screen cylinder 3 rotates.

[0023] Specifically, during use, the external dyeing and finishing wastewater pipe is fixed above the screen cylinder 3 with the pipe frame 202 and external straps. The wastewater is initially filtered through the screen cylinder 3, blocking large particles of solid impurities. Then, flocculant is manually added, and the mixing module 5 is started to stir the liquid in the mixing tank 1. The wastewater then enters the sedimentation tank 6 and settles with the sedimentation module 7 before flowing out to the outside.

[0024] Example 1

[0025] like Figure 1-3 As shown, a first gearbox 101 is fixedly connected to the upper surface of the mixing tank 1, a first motor 102 is fixedly connected to the side surface of the first gearbox 101, the output end of the first motor 102 is fixedly connected to the input end of the first gearbox 101, a first gear 103 is fixedly connected to the output end of the first gearbox 101, a second gear 104 is fixedly connected to the outer surface of the screen cylinder 3, and the first gear 103 and the second gear 104 are meshed together. A pipe frame 202 is fixedly connected to the upper surface of the mounting frame 2, and the pipe frame 202 is used to fix the external wastewater pipes.

[0026] In this embodiment, the first motor 102 is started, which causes the first gearbox 101 to drive the first gear 103 to rotate, and further causes the second gear 104 to drive the screen cylinder 3 to rotate, which in turn causes the screen cylinder 3 to drive the mixing module 5 to rotate, and the mixing module 5 stirs the inside of the mixing tank 1.

[0027] like Figure 2-3 As shown, the mixing module 5 includes a mounting sleeve 501, which is nested on the outer surface of the sieve cylinder 3. An annular corrugated plate 502 is fixedly connected to the outer surface of the mounting sleeve 501. A connecting frame 503 is fixedly connected to the upper surface of the mounting sleeve 501. A stirring protrusion 504 is fixedly connected to the outer surface of the connecting frame 503. A limiting sleeve 505 is fixedly installed on the inner wall of the mixing tank 1. A vertical rod 506 is slidably connected to the upper surface of the limiting sleeve 505. A rotating roller 507 is rotatably connected to the end of the vertical rod 506. The rotating roller 507 is in contact with the annular corrugated plate 502. A stirring blade is fixedly connected to the outer surface of the vertical rod 506. A spring 508 is nested on the outer surface of the vertical rod 506. One end of the spring 508 is in contact with the mounting sleeve 501, and the other end of the spring 508 is in contact with the stirring blade.

[0028] In this embodiment, the mounting sleeve 501 is installed on the outer surface of the screen cylinder 3 with external bolts. When the screen cylinder 3 rotates, the mounting sleeve 501, the annular wave plate 502, and the connecting frame 503 rotate synchronously. The stirring protrusions 504 on the connecting frame 503 mix the wastewater, and when the annular wave plate 502 rotates, it applies an upward force to the rotating roller 507. Under the elastic force of the spring 508, the vertical rod 506 always has a downward movement tendency, which makes the vertical rod 506 shake up and down to further cooperate with the stirring blade to make the wastewater turbulent and optimize the mixing effect of the device.

[0029] Example 2

[0030] Based on Example 1, in order to overcome the problem of inconvenience in settling wastewater in Example 1.

[0031] like Figure 1-4 As shown, a connecting square tube 601 is fixedly connected to the outer surface of the sedimentation tank 6, and the connecting square tube 601 is connected and conductive to the mixing tank 1. A baffle 602 is fixedly connected to the inside of the sedimentation tank 6, and a limit strip 603 is fixedly connected to the inner wall of the sedimentation tank 6. A discharge door 604 is hinged to the outer surface of the sedimentation tank 6. The sedimentation module 7 includes a movable seat 702, which is slidably connected to the upper surface of the limit strip 603. A hydraulic cylinder 701 is fixedly connected to the inside of the sedimentation tank 6, and the output end of the hydraulic cylinder 701 is fixedly connected to the movable seat 702. The inner surface of the movable seat 702 is slidably connected to... There is an inclined tube 703, and a feeding auger 704 is rotatably connected inside the settling tank 6.

A synchronous belt 706 is nested on the outer surface of the synchronous pulley 705. A second gearbox 707 is fixedly connected inside the settling tank 6. A second motor 708 is fixedly connected to the outer surface of the second gearbox 707. The output end of the second motor 708 is fixedly connected to the input end of the second gearbox 707. The input end of the second gearbox 707 is fixedly connected to the feeding auger 704.

[0032] In this embodiment, wastewater enters the sedimentation tank 6 from the connecting square pipe 601. The baffle 602 blocks the water flow, reducing the impact of the water flow on the inclined pipe 703. The inclined pipe 703 is used to settle the wastewater. When the inclined pipe 703 needs to be replaced, the hydraulic cylinder 701 is started. The output end of the hydraulic cylinder 701 pushes the moving seat 702 to move. At this time, the inclined pipe 703 can be manually pulled out along the moving seat 702 for replacement. When discharging, the discharge door 604 is opened, the second motor 708 is started, and the second reduction gearbox 707, together with the synchronous belt 706 and the synchronous pulley 705, drives multiple feeding augers 704 to rotate. The sedimented impurities are discharged under the conveying of the feeding augers 704.
