Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to a sewage treatment system. Background Art

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it. Sewage treatment is widely applied in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people.

[0003] In the prior art, flocculants are usually used to purify sewage. Flocculants can aggregate fine particles and natural colloidal particles in water into large flocs, thereby purifying the sewage. In order to make the sewage react well with the flocculants, stirring of the sewage is required. However, the flocculants will be subjected to shear degradation of the polymer caused by the high-speed rotating blades, changing their properties and unable to play their normal roles. If the flocculants are not stirred, it is very difficult to fully mix the flocculants and the sewage. Excessive flocculants will aggregate together, and not all flocculants can play their roles, resulting in waste of flocculants. Summary of the Utility Model

[0004] In order to solve the technical problem that the existing sewage treatment equipment cannot well mix the flocculants and sewage evenly, the utility model provides a sewage treatment system.

[0023] It should be noted that most sewage treatment equipment cannot mix the flocculant and sewage well, resulting in the failure of all flocculants to play a role, which is not conducive to the purification treatment of sewage;

[0024] In this embodiment, when sewage needs to be purified, first, a certain amount of sewage enters the mixing tank 2 through a water inlet pipe on one side of the cleaning tank 3, and then the flocculant is poured into the mixing tank 2 through a feed hopper on one side of the cleaning tank 3. Then, the first motor 7 is started, and the output shaft of the first motor 7 drives the gear 6 to rotate, so that the gear 6 drives the gear ring 5 to drive the mixing tank 2 to rotate, causing the sewage in the mixing tank 2 to rotate, and thus making it contact the flocculant evenly, thereby causing a chemical reaction. When the mixing tank 2 is rotated, the mixing mechanism is simultaneously driven to mix the sewage, which is beneficial for it to contact the flocculant evenly;

[0025] After the sewage has fully reacted, start the cleaning mechanism to clean the flocs in the sewage. After the cleaning, the sewage can be discharged outside the mixing tank 2 for subsequent treatment.

[0027] In this embodiment, when driving the mixing tank 2 to rotate, start the electric telescopic rod 11 to drive the output rod of the electric telescopic rod 11 to drive the cable 12 to slide, so that the cable 12 drives the slide plate 9 to slide up and down along the support rod 8, thereby making the slide plate 9 disturb the flow of the sewage, and then making it uniformly contact with the flocculant, which is beneficial to the purification treatment of the sewage.

[0028] In a further preferred embodiment of the present utility model, a return spring 13 is sleeved on the support rod 8, and both ends of the return spring 13 are fixedly connected to the support rod 8 and the slide plate 9 respectively.

[0029] In this embodiment, through the arrangement of the guide wheels 14, it is beneficial to guide the cable 12, thereby ensuring the smooth sliding of the slide plate 9 and being beneficial to the sewage disturbing flow operation.

[0030] In a further preferred embodiment of the present utility model, the cleaning mechanism includes: a collection box 15 fixedly installed on one side of the cleaning box 3; a one-way screw 16 rotatably installed in the cleaning box 3; a scraper 17 sleeved on the one-way screw 16, and the scraper 17 is in sliding contact with the inner wall of the cleaning box 3; a second motor 18 fixedly installed on one side of the cleaning box 3, and the output shaft of the second motor 18 is fixedly connected to the one-way screw 16.

[0031] In this embodiment, when it is necessary to clean the flocs, first start the second motor 18 to drive the output shaft of the second motor 18 to drive the one-way screw 16 to rotate, so that the one-way screw 16 drives the scraper 17 to slide along the inner wall of the cleaning box 3, and then scrape the flocs into the collection box 15, thereby completing the cleaning operation of the flocs.

[0032] In a further preferred embodiment of the present utility model, an arc-shaped plate 19 is fixedly installed in the cleaning box 3, the arc-shaped plate 19 is located below the one-way screw 16, and the arc-shaped plate 19 is slidably connected to the scraper 17.

[0033] In this embodiment, the one-way screw 16 is protected by the arc-shaped plate 19 to ensure that the flocculent substances do not come into contact with the one-way screw 16, which is beneficial to the operation of the cleaning mechanism.

[0034] In a further preferred embodiment of the present utility model, a filter screen 20 is fixedly installed in the collection box 15. The filter screen 20 is arranged in an inclined shape. One side of the collection box 15 is fixedly installed with a water pump 21. Both ends of the water pump 21 are respectively connected to the collection box 15 and the cleaning box 3.

[0035] In this embodiment, while cleaning the flocculent substances, the water pump 21 is started to pump the sewage in the collection box 15 into the cleaning box 3 for sewage reflux operation, which is beneficial to the subsequent cleaning operation of the flocculent substances in the collection box 15.

[0040] In summary, the device mixes the sewage and the flocculant through the self-rotation of the mixing box 2, with high mixing efficiency, and does not change the properties of the flocculant, which is beneficial to the uniform and full mixing of the flocculant and the sewage.

[0041] Compared with the related art, the gear 6 drives the ring gear 5 to drive the mixing tank 2 to rotate, so that the sewage in the mixing tank 2 rotates, and then it is uniformly contacted with the flocculant, thereby causing a chemical reaction, and the mixing efficiency is relatively high. The cable 12 drives the slide plate 9 to slide up and down along the support rod 8, so that the slide plate 9 turbulates the sewage, and then it is uniformly contacted with the flocculant, which is beneficial to the purification treatment of the sewage. The cleaning mechanism is used to clean the flocs, and then the sewage is separated from the flocs, which is beneficial to the subsequent further treatment of the sewage.
