Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an integrated coagulation and sedimentation wastewater treatment device. Background Technology

[0002] In wastewater treatment, to effectively purify the wastewater, it is coagulated before sedimentation to achieve rapid treatment. For example, patent document CN203922822U discloses an integrated coagulation and sedimentation wastewater treatment device. This device improves the coagulation-sedimentation process by using inner, middle, and outer cylinders to form a coagulation chamber, a flocculation chamber, and a sedimentation chamber. The entire device has the functions of coagulation, flocculation, coagulation, sedimentation, and separation, realizing integrated equipment. The use of spiral guide plates and multi-layer perforated plates further improves the coagulation efficiency of wastewater and reduces the volume of coagulation, sedimentation, and separation equipment, thereby saving engineering investment. The device is flexible in its use and can be used alone or in combination with other treatment units depending on the actual situation.

[0003] Existing treatment equipment requires the pre-addition of coagulants during coagulation and sedimentation. The traditional method involves operators directly adding the coagulant to a fixed area, which prevents the coagulant from fully mixing with the wastewater and reduces the coagulation effect.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses an integrated device for coagulation and sedimentation wastewater treatment.

[0027] Example 1

[0028] This utility model provides, for example Figure 1-4 The integrated coagulation and sedimentation wastewater treatment device shown includes a treatment cylinder 1 and a support frame 2 fixedly installed on the top of the treatment cylinder 1. A control motor 3 is fixedly installed at the bottom of the treatment cylinder 1. The output shaft end of the control motor 3 passes through the treatment cylinder 1 and is fixedly installed with a stirring shaft 4. A stirring blade 5 is fixedly sleeved on the shaft wall of the stirring shaft 4.

[0029] An elastic telescopic rod 6 is fixedly provided at the bottom of the stirring shaft 4, and a coagulant hopper 7 is fixedly provided at the end of the elastic telescopic rod 6;

[0030] The support frame 2 has multiple radially evenly distributed strip holes 10 inside. A moving material spreading mechanism for driving the coagulant hopper 7 to move is provided between the strip holes 10 and the elastic telescopic rod 6. The moving material spreading mechanism includes a crossbar 11, which is fixedly installed in the strip holes 10 and has a slider 12 slidably sleeved on its wall. A magnetic ring 13 is fixedly sleeved on the end of the elastic telescopic rod 6, and an adsorption magnetic block 14 that magnetically cooperates with the magnetic ring 13 is fixedly installed at the bottom of the slider 12.

[0031] The top of the support frame 2 is fixed with two symmetrically arranged support columns 15. The top of the two support columns 15 is fixed with a push cylinder 16. The output shaft end of the push cylinder 16 is fixed with a slide plate 17. The side of the slide plate 17 and the top of the slider 12 are both fixed with connecting plates 18. The two connecting plates 18 on the same side rotate together to form a push plate 19.

[0032] Example 2

[0033] Example 2, based on Example 1, aims to ensure stable addition and discharge of the coagulant, such as... Figure 1-2 and Figure 4 As shown, the bottom of the coagulant hopper 7 is connected to a discharge pipe 8, and a control valve 9 is fixedly sleeved on the pipe wall of the discharge pipe 8. A transparent indicator plate 22 is fixedly embedded on the side of the coagulant hopper 7. The bottom of the processing cylinder 1 is connected to a discharge pipe 20, and a material control valve 21 is fixedly sleeved on the pipe wall of the discharge pipe 20.

[0034] Working principle: First, the wastewater to be treated is injected into the treatment cylinder 1. At the same time, the amount of coagulant is observed through the transparent indicator plate 22 of the coagulant hopper 7 to ensure that the coagulant is sufficient. Then, the electric cylinder 16 is activated. The output shaft of the electric cylinder 16 drives the slide plate 17 to move along the support column 15. The connecting plate 18 on the side of the slide plate 17 moves accordingly. The push plate 19 pushes the connecting plate 18 on the top of the slider 12, so that the slider 12 slides along the crossbar 11 in the strip hole 10.

[0035] The magnetic block 14 at the bottom of the slider 12 is magnetically engaged with the magnetic ring 13 at the end of the elastic telescopic rod 6. When the slider 12 moves, the elastic telescopic rod 6 moves synchronously through magnetic force. The elastic telescopic rod 6 extends and retracts adaptively according to the movement trajectory, thereby driving the coagulant hopper 7 at the end to move radially in the treatment cylinder 1. At this time, the control valve 9 (electromagnetic control valve) on the wall of the discharge pipe 8 is opened, and the coagulant in the coagulant hopper 7 is evenly spread to the surface of the sewage through the discharge pipe 8, so as to realize the all-round and uniform delivery of coagulant on the surface of sewage.

[0036] At the same time, the control motor 3 at the bottom of the treatment cylinder 1 is started. The output shaft of the control motor 3 drives the stirring shaft 4 to rotate. The stirring blades 5 on the shaft wall of the stirring shaft 4 rotate together to fully stir the mixture of sewage and coagulant, so that the suspended solids and colloidal particles in the sewage react with the coagulant to form flocs. While the stirring shaft 4 drives the coagulant hopper 7 to rotate laterally, multiple sliders 12 move laterally under the continuous operation of the electric cylinder 16, so that the coagulant hopper 7 can be reciprocated when it rotates to the bottom of each slider 12, so that the coagulant can be evenly distributed to the surface of the sewage.

[0037] After the coagulation reaction is complete, stop stirring and let it stand for a period of time to allow the flocs to settle naturally in the treatment tank 1. After the sedimentation is complete, separate the clear water from the sediment and remove it for further treatment.

[0038] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
