Technical Field

[0001] The utility model relates to the field of wastewater treatment, and particularly relates to a treatment device for dyeing and finishing wastewater. Background Technique

[0002] The wastewater discharged from printing and dyeing, wool weaving and dyeing finishing, silk factories, etc. mainly processing cotton, linen, chemical fibers and their blended products, silk, etc. The water volume and water quality of the printing and dyeing wastewater are different due to different fiber types and processing technologies. Among them, the wastewater volume of printing and dyeing factories is relatively large. For every 1 ton of textile printed and dyed, 100-200 tons of water is consumed, and 80%-90% of it becomes wastewater and is discharged. Printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large water quality changes. It is one of the industrial wastewaters that are difficult to treat. The wastewater contains dyes, sizing agents, auxiliaries, oil agents, acids and alkalis, fiber impurities, sand substances, inorganic salts, etc. Generally, neutralizing agents such as lime and alkali lime are added to neutralize the acidic or alkaline substances in the wastewater to neutral, and adjust the pH value of the wastewater;

[0003] In the treatment of wastewater, generally, the wastewater is treated with a neutralizing agent. Generally, the wastewater and the neutralizing agent are directly mixed, and then a stirring mechanism is used to accelerate the mixing. This method can only mix the non-flowing wastewater in the container, and the mixing method is relatively slow. When the wastewater volume is relatively high, the mixing time is greatly increased;

[0004] Therefore, it is very necessary to propose a treatment device for dyeing and finishing wastewater to solve the above problems. Content of the Utility Model

[0012] The technical effects and advantages of the present utility model:

[0013] 1. Through the arrangement of the bulk material shell, the flow rate of water is utilized to drive the rotation of the bulk material shell, thereby putting the neutralizing agent. And due to the flow rate of water, when the flow rate of water is relatively fast, the rotation speed of the bulk material shell is increased to increase the addition ratio of the neutralizing agent, and vice versa when the water flow rate is slow, reducing the addition of the neutralizing agent to the flowing wastewater;

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the scope of protection of the present utility model.

[0023] The present utility model provides a treatment device for dyeing and finishing wastewater as shown in Figure 1 - Figure 5 which includes a drain pipe 1. The drain pipe 1 is a pipe for transporting waste liquid and is a prior art, so no more description will be given here.

[0024] When treating wastewater, a neutralizing agent is generally added to treat the wastewater. The neutralizing agent is generally lime, soda lime, etc. and is in the form of granular powder.

[0025] A storage shell 2 for storing the neutralizing agent is fixedly provided at the upper end of the drain pipe 1. A dispersing shell 3 is rotatably provided inside the drain pipe 1. A plurality of scraping plates 7 for releasing the neutralizing agent are fixedly provided on the outer side of the dispersing shell 3. A plurality of baffles 9 for adjusting the dosage of the neutralizing agent are provided on the outer side of the dispersing shell 3. The baffles 9 are arc-shaped and can better fit the outer side of the dispersing shell 3. The baffles 9 are made of rubber and have a certain deformable elastic ability to adapt to their shape between the two scraping plates 7. A plurality of guiding holes 15 are opened on the outer side of the dispersing shell 3. A telescopic plate 8 is slidably provided inside the guiding holes 15. One end of the telescopic plate 8 is fixedly connected to the baffle 9, and the end of the baffle 9 contacts one end of the scraping plate 7.

[0026] A circular hole 5 is opened inside the dispersing shell 3. A rotating column 6 is rotatably provided inside the circular hole 5. Two turntables 10 are fixedly provided on the outer side of the rotating column 6. One end of each of the two turntables 10 contacts the inner wall of the circular hole 5. A plurality of fixed shafts 11 are fixedly provided at one end of the turntable 10. A transmission rod 12 is rotatably provided on the outer side of the fixed shaft 11. The end of the transmission rod 12 is rotatably connected to the end of the telescopic plate 8.

[0027] A linkage sleeve 13 is fixedly provided at one end of the dispersing shell 3. The rotating column 6 passes through the linkage sleeve 13 movably. A fastening nut 14 is provided on the outer side of the rotating column 6 in a threaded manner. A driving handle is fixedly provided at the end of the rotating column 6.

[0028] Two partition plates 4 are fixedly provided on the outer side of the dispersing shell 3 to prevent the neutralizing agent from entering the inside of the drain pipe 1 from other parts. A through hole for the partition plate 4 to pass through is opened on the outer side of the drain pipe 1. The outer circle of the partition plate 4 only contacts the inner wall of the through hole and does not contact the inner wall of the drain pipe 1.

[0029] The inner side of the storage shell 2 is arranged in an inverted conical shape to increase the force on the neutralizing agent near the lower part of the inner wall of the storage shell 2.

[0030] Working principle: The operator adds neutralizing agents such as lime and soda lime into the interior of the storage shell 2, and then opens the wastewater switch valve, allowing the wastewater to enter the drain pipe 1. The wastewater then impacts the scraper 7 on the bulk material shell 3, and the flowing water is used to drive the rotation of the bulk material shell 3. The scraper 7 then drives a certain amount of neutralizing agent into the flowing wastewater to add the neutralizing agent to the wastewater. Due to the water flow rate, when the water flow rate is fast, the rotation speed of the bulk material shell 3 is increased to increase the addition ratio of the neutralizing agent. Conversely, when the water flow rate is slow, the addition of the neutralizing agent to the flowing wastewater is reduced.

[0031] When the proportion of the neutralizing agent to be added to the wastewater needs to be increased, the fastening nut 14 is turned to move the fastening nut 14 away from the linkage sleeve 13, which can drive the rotating column 6, causing the rotating column 6 to drive the turntable 10 to rotate clockwise, driving the fixed shaft 11 to rotate, causing the end of the fixed shaft 11 to drive the movement of the transmission rod 12, and the transmission rod 12 to drive the telescopic plate 8 to move towards the rotating column 6 within the guide hole 15, causing the telescopic plate 8 to drive the baffle 9 to move, thereby increasing the amount of neutralizing agent that the scraper 7 can carry out and increasing the usage ratio of the neutralizing agent.

[0032] When the proportion of the neutralizing agent needs to be reduced, the rotating column 6 is rotated counterclockwise. After the adjustment is completed, the fastening nut 14 is turned to press the rotating column 6 so that it cannot rotate.
