Description

Technical Field

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

[0002] Wastewater discharged from the dyeing and finishing of silk and wool textiles is called dyeing and finishing wastewater. This wastewater is characterized by large volume, high content of organic pollutants, high alkalinity, and large fluctuations in water quality. It is one of the most difficult industrial wastewaters to treat. The wastewater contains dyes, sizing agents, auxiliaries, oils, acids and alkalis, fiber impurities, sand, inorganic salts, etc.

[0003] Currently, when treating dyeing and finishing wastewater, chemical reagents such as solid decolorizing agents and polyaluminum chloride solution flocculants are mixed with the wastewater for flocculation treatment. In wastewater treatment tanks, a motor-driven stirring shaft with ordinary plate-type stirring blades is typically used to stir the wastewater and chemical reagents for mixing and reaction. The relatively simple stirring blades in the wastewater treatment tank have low impact and stirring effect on the wastewater, resulting in a long mixing reaction time between the dyeing and finishing wastewater and the chemical reagents, thus affecting the treatment efficiency of dyeing and finishing wastewater. Therefore, we propose a dyeing and finishing wastewater treatment device. Utility Model Content

[0004] The main objective of this invention is to provide a dyeing and finishing wastewater treatment device. A stirring mechanism is installed outside the stirring shaft of the wastewater treatment tank. The stirring shaft can rotate the multi-layered, multi-style stirring structure of the stirring mechanism to stir the dyeing and finishing wastewater and chemical reagents within the wastewater treatment tank. Furthermore, an ultrasonic transducer is located at the support beam of the wastewater treatment tank to transmit ultrasonic waves into the liquid within the tank. The ultrasonic cavitation effect vibrates and stirs the dyeing and finishing wastewater and chemical reagents, ensuring efficient stirring and reaction flocculation treatment of the wastewater in the wastewater treatment tank. This effectively solves the problems in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A dyeing and finishing wastewater treatment device includes a wastewater treatment tank, a support beam, and a stirring shaft. The support beam is fixed inside the opening of the wastewater treatment tank, and a stirring shaft extending into the wastewater treatment tank is rotatably mounted on the middle of the support beam. The device also includes a stirring mechanism, which comprises an L-shaped paddle pair, a middle support plate, an outer support plate, a curved plate, a vertical foot, a vertical support plate, a counter-support paddle, an N-shaped paddle plate, a vertical cylinder, a stop ring, a vibration transmission plate, and an ultrasonic transducer. An L-shaped paddle pair is welded in a figure-eight shape to the bottom shaft of the stirring shaft, and a middle support plate is welded between the vertical inclined plate of the L-shaped paddle pair and the stirring shaft. An outer support plate is welded to the surface of the stirring shaft outside the middle support plate. A sag plate is welded between the upper surface of the short plate of the paddle and the stirring shaft. A vertical foot extending between the sag plate and the L-shaped paddle is welded to the lower surface of the middle support plate. A vertical support plate is symmetrically welded to the upper plate of the middle support plate, and opposing anti-reverse paddles are symmetrically welded to both sides of the vertical support plate. An N-shaped paddle plate is welded to the upper plate of the outer support plate. Vertical holes are symmetrically opened on the surface of the support beam outside the stirring shaft, and a vertical cylinder extending between the vertical support plates is inserted into the vertical holes. A vibration plate is vertically fixed inside the vertical cylinder, and an ultrasonic transducer installed on the surface of the vibration plate is inserted inside the vertical cylinder. A stop ring that presses against the upper surface of the support beam is welded to the outer wall of the vertical cylinder.

[0007] Furthermore, four sets of curved sag plates are welded between the stirring shaft and the L-shaped paddles; the presence of multiple curved sag plates between the stirring shaft and the L-shaped paddles allows for the stirring of dyeing and finishing wastewater and chemical reagents.

[0008] Furthermore, two sets of N-shaped paddles are symmetrically welded on the surface of the outer support plate; the outer support plate has a large number of N-shaped paddles that can stir dyeing and finishing wastewater and chemical reagents.

[0009] Furthermore, four sets of vertical legs are symmetrically welded on the lower surface of the central support plate; the lower surface of the central support plate has a number of vertical legs that can stir dyeing and finishing wastewater and chemical reagents.

[0010] Furthermore, a stud is fixed to the surface of the vibration plate, and the ultrasonic transducer is screwed onto the stud of the vibration plate; the ultrasonic transducer can be installed by screwing onto the stud of the vibration plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention features a stirring mechanism installed outside the stirring shaft of the wastewater treatment tank. The stirring shaft, carrying the multi-layered and multi-style stirring structure of the stirring mechanism, rotates and stirs the dyeing and finishing wastewater and chemical reagents in the wastewater treatment tank. Furthermore, an ultrasonic transducer is located at the support beam of the wastewater treatment tank, which transmits ultrasonic waves into the liquid within the wastewater treatment tank. By utilizing the cavitation effect of the ultrasonic waves, the dyeing and finishing wastewater and chemical reagents are vibrated and stirred, ensuring efficient stirring of the dyeing and finishing wastewater and chemical reagents in the wastewater treatment tank for reaction and flocculation treatment.

An N-shaped paddle plate 12 is welded to the upper plate surface of the outer support plate 7. Vertical holes 13 are symmetrically opened on the surface of the support beam 2 outside the stirring shaft 3, and a vertical cylinder 14 extending between the vertical support plates 10 is inserted into the vertical holes 13. A vibration transmission plate 16 is vertically fixed inside the vertical cylinder 14, and an ultrasonic transducer 17 installed on the surface of the vibration transmission plate 16 is inserted into the vertical cylinder 14. A stop ring 15 pressing against the upper surface of the support beam 2 is welded to the outer wall of the vertical cylinder 14.

[0019] The curved sag plate 8 is welded in four sets between the stirring shaft 3 and the L-shaped paddle 5; the multiple curved sag plates 8 welded between the stirring shaft 3 and the L-shaped paddle 5 can stir dyeing and finishing wastewater and chemical reagents.

[0020] Among them, two sets of N-shaped paddles 12 are symmetrically welded on the surface of the outer support plate 7; the surface of the outer support plate 7 has a large number of N-shaped paddles 12 that can stir dyeing and finishing wastewater and chemical reagents.

[0021] The vertical legs 9 are symmetrically welded to the lower surface of the middle support plate 6 in four groups; the lower surface of the middle support plate 6 has a large number of vertical legs 9 that can stir dyeing and finishing wastewater and chemical reagents.
