Description

TECHNICAL FIELD

[0002] Domestic sewage contains a large amount of organic matter, bacteria and the like, which are harmful to the environment, and many parts of the sewage are acidic or alkaline. Direct discharge of the acidic or alkaline sewage will cause harm to the environment and aquatic organisms. Therefore, before the sewage is directly discharged into the external environment, the harmful substances need to be removed and the acid-base neutralization treatment needs to be performed.

[0003] The sewage treatment device for water pollution treatment has some deficiencies in actual use.

[0004] 1. The traditional acid-base neutralization treatment device usually adopts a simple stirring and mixing method to add acid or alkali directly into a sewage tank for neutralization reaction. However, this method has problems such as uneven mixing, low reaction efficiency, incomplete neutralization and the like, which result in that the treated sewage is difficult to meet the discharge standard stably.

[0005] 2. In actual use, the pH detector of the traditional sewage treatment device for water pollution treatment usually only targets a single position, and cannot comprehensively reflect the actual neutralization state of the sewage in the tank, which results in lagging adjustment or error. In addition, the probe of the pH detector is easily attached and contaminated by impurities in the sewage when it is soaked in the sewage for a long time, which results in inaccurate detection data. The cleaning and maintenance of the pH detector are complicated. Therefore, the existing structure and defects are improved, and the sewage treatment device for water pollution treatment is provided, so as to achieve the purpose of having more practical value.

[0017] Compared with the prior art, the present application has the following beneficial effects:

[0018] I. The sewage treatment device for water pollution control is provided with multiple mixing plates with angle difference in the mixing pipe, which can preliminarily mix the acid agent or alkali agent with the sewage before entering the neutralizing tank. In the neutralizing tank, the convex strips on the conical disc disperse the sewage, the stirring blades stir and mix the sewage, and the honeycomb-shaped turbulence net plate reciprocates up and down to enhance the turbulence. The multiple-stage mixing mode improves the contact area and mixing uniformity of the sewage and the agent, greatly accelerates the neutralization reaction speed, and improves the sewage treatment efficiency and effect.

[0019] II. The PH detector one on the connecting pipe of the sewage treatment device for water pollution control monitors the acid-base degree of the sewage entering the device in real time, providing data support for the addition of the acid agent or alkali agent. The PH detector two in the neutralizing tank can accurately detect the acid-base degree of the sewage at different depths in the tank by adjusting the depth of the detection head, and real-time feedback the neutralization state of the sewage, ensuring that the treated sewage reaches the neutral standard.

[0020] III. Multiple PH detectors two are equidistantly installed in the accommodation grooves on the surface of the rotating drum in the detection shell and are distributed along the height direction of the rotating drum, which can detect the acid-base degree of the sewage at multiple depths in the neutralizing tank. The multi-point detection can comprehensively reflect the acid-base degree of the sewage in the neutralizing tank, avoiding the error of single-point detection and ensuring the accuracy and reliability of the detection results.

[0021] IV. The small hole structure of the honeycomb-shaped turbulence net plate divides and recombines the sewage, increases the mixing opportunities between different parts of the sewage, helps to break the concentration gradient in the sewage, and ensures that the agent is more evenly distributed in the sewage, so that the neutralization reaction can be carried out under more uniform conditions. The honeycomb-shaped turbulence net plate reciprocates up and down under the action of the cam and spring one, which produces turbulence effect on the passing sewage. The dynamic turbulence effect increases the contact area and time of the sewage and the agent, promotes the neutralization reaction to be carried out more fully, helps to improve the quality and efficiency of the sewage treatment, and makes the treated sewage closer to the neutral standard.

[0022] V. The sealing element one in the communication port seals the rotating drum, preventing the sewage in the neutralizing tank from leaking between the rotating drum and the inner wall of the communication port to the cleaning port. The sealing ring inside the detection shell seals the rotating shaft three, and the arc-shaped baffle seals the cleaning port, forming a double-sealing structure, which effectively prevents the sewage in the neutralizing tank from leaking, ensures the safety and stability of the sewage treatment device, and avoids the secondary pollution to the environment caused by the leakage of the sewage.

[0023] VI. When PH detector two needs to be cleaned, start motor two, so that the rotating drum drives PH detector two to rotate to the cleaning port, facilitating the staff to clean, at the same time, the rotation of the arc-shaped baffle realizes the opening and closing of the cleaning port, ensures the convenience and sealing of the cleaning process, facilitates the daily maintenance of the detector, ensures the detection accuracy, prolongs the service life of PH detector two.

[0057] The working principle of the embodiment is as follows:

[0058] First step: when the sewage treatment device is used, the sewage is quantitatively conveyed into the mixing pipe 2 through the connecting pipe 22, the sewage flows into the neutralization tank 1 from the L-shaped pipe 23 communicated with the middle part of the upper end of the mixing pipe 2, the PH detector one 29 installed on the connecting pipe 22 monitors the pH value of the sewage in real time, according to the pH value data of the sewage fed back by the PH detector one 29, the system accurately inputs the quantitative acid or alkali agent into the mixing pipe 2 through the control of the metering pump 27, a plurality of mixing plates 21 are distributed along the axial direction in the mixing pipe 2, and there is an angle difference between adjacent mixing plates 21, so as to promote the acid or alkali agent and the sewage to be fully mixed in the mixing pipe 2, and then conveyed into the neutralization tank 1, which lays a foundation for more efficient neutralization reaction in the neutralization tank 1;

[0059] Second step: the sewage conveyed into the neutralization tank 1 first falls into the middle part of the conical disc 42, at this time, the motor one 5 is started, the output shaft of the motor one 5 drives the driving shaft 51 to rotate, the driving shaft 51 drives the stirring shaft 4 to rotate through the engagement of the conical gear one 44 and the conical gear two 52 on the stirring shaft 4, the rotation of the stirring shaft 4 drives the conical disc 42 and a plurality of stirring blades 41 to rotate, the convex strips 43 equally distributed on the upper end of the conical disc 42 disperse the falling sewage, so that the sewage is more evenly distributed in the neutralization tank 1, at the same time, the stirring blades 41 stir and mix the sewage falling on the bottom of the cavity in the neutralization tank 1, so as to accelerate the sewage to fully contact with the acid or alkali agent preliminarily mixed in the mixing pipe 2 and to occur neutralization reaction.

[0060] Third step: the sewage dispersed through the convex strip 43 first passes through the honeycomb-shaped turbulence net plate 3, and then falls into the neutralization tank 1 and is stirred and mixed by the stirring blade 41. The driving shaft 51 is driven by the synchronous pulley one 53 and the synchronous belt one 54 and the rotating shaft one 7. When the driving shaft 51 rotates, the rotating shaft one 7 is driven to rotate, and then the cam 71 on the rotating shaft one 7 rotates. When the convex part of the cam 71 contacts the surface of the spherical ball 32 at the bottom end of the lug block 31, an upward force is applied to the lug block 31, so that the honeycomb-shaped turbulence net plate 3 overcomes the elastic force of the spring one 34 and moves up. When the convex part of the cam 71 rotates away from the spherical ball 32, the honeycomb-shaped turbulence net plate 3 moves down and resets under the resetting action of the spring one 34. With the continuous rotation of the rotating shaft one 7 and the cam 71, the honeycomb-shaped turbulence net plate 3 moves up and down repeatedly, further enhancing the turbulence effect of the sewage, so that the sewage is mixed with the acid or alkali more fully when passing through the honeycomb-shaped turbulence net plate 3, which helps to improve the efficiency and effect of the neutralization reaction.

[0061] Fourth step: multiple PH detectors two 92 are installed in the detection shell 6 installed on the side end of the neutralization tank 1, and multiple PH detectors two 92 are installed in the accommodation groove 91 on the surface of the rotating drum 9. The multiple PH detectors two 92 are distributed along the height direction of the rotating drum 9, and can detect the acidity and alkalinity of the sewage at multiple different depths in the neutralization tank 1. The sealing element one 65 arranged in the communication port 61 seals the rotating drum 9. The sealing ring arranged in the detection shell 6 seals the rotating shaft three 93. In addition, the arc-shaped baffle 95 seals the cleaning port 62, forming a double-sealing structure, which effectively prevents the sewage in the neutralization tank 1 from leaking out of the cleaning port 62. When the detection data of the multiple PH detectors two 92 all meet the discharge standard, the liquid outlet pipe 11 is opened, and the sewage meeting the standard is discharged from the liquid outlet pipe 11. If the detection data does not meet the standard, appropriate acid or alkali can be added through the standby adding pipe 12 arranged on the upper part of the side end of the neutralization tank 1, to further adjust the acidity and alkalinity of the sewage.

[0062] Fifth step: when the probe on the PH detector two 92 needs to be cleaned, start the motor two 8, the output shaft of the motor two 8 drives the driving shaft 81 to rotate, the driving gear 82 and the synchronous wheel two 83 fixedly installed on the driving shaft 81 rotate with it, when the driving gear 82 rotates, the driven gear 84 meshed with it rotates, the driven gear 84 rotates and drives the rotating shaft two 85 to rotate, the rotating shaft two 85 is connected with the arc baffle 95 through the connecting rod 86, so as to drive the arc baffle 95 to rotate around the rotating shaft three 93, when the arc baffle 95 rotates, it is retracted into the arc-shaped groove 64, at this time, the arc baffle 95 no longer covers the cleaning port 62, at the same time, the synchronous wheel two 83 rotates and drives the synchronous wheel three 94 and the rotating shaft three 93 to rotate through the synchronous belt two 87, so that the rotating cylinder 9 rotates around the rotating shaft three 93, since the output shaft of the motor two 8 is provided with an encoder, the rotating cylinder 9 can be accurately controlled to rotate one hundred and eighty degrees, so as to drive the PH detector two 92 to rotate to face the outside, at this time, a plurality of PH detectors two 92 are located at the cleaning port 62, which is convenient for the staff to clean, after cleaning, start the motor two 8 again, so that the rotating cylinder 9 and the arc baffle 95 reset, restore the sealing state of the detection shell 6, and ensure that the sewage treatment device continues to operate normally.
