Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a sewage treatment mud discharge device. Background Art

[0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for drainage into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. People are making more and more use of water resources, and a certain amount of wastewater will be generated when using water sources. Direct discharge will pollute the environment and needs to be treated in a sedimentation tank. Sludge will be generated during the treatment and needs to be discharged separately.

[0003] However, during sewage sedimentation, sludge tends to accumulate and adhere to the inclined side walls below the sedimentation tank, so incomplete sludge discharge may occur during sludge discharge. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a sewage treatment sludge discharge device, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a sewage treatment mud discharge device, comprising a sedimentation tank, a sedimentation bin is arranged in the middle of the sedimentation tank, a mud storage bin is installed on the lower surface of the sedimentation bin, a middle baffle is installed above the mud storage bin, discharge baffles are symmetrically installed on both sides below the middle baffle, side baffles are arranged above the two discharge baffles on the side away from the middle baffle, scrapers are arranged on both ends of the inner side of the sedimentation bin, side limit grooves are arranged on the two side sections of the scraper, a spring is installed on the lower surface of the scraper, a pull rope is connected between the scraper and the discharge baffle, and a limit ring is installed above the side baffle and on the outer side of the pull rope.

[0006] As a further solution of the utility model: a driving motor is installed on the side surface of the sedimentation tank at one end of the discharge baffle through a rotating shaft, and a dispersion mechanism is installed inside the sedimentation tank.

[0009] As a further solution of the utility model: the scraper plate is slidably connected to the side limit groove, the pull rope is fixedly connected to the scraper plate and the discharge baffle, and the discharge baffle is clamped to the middle baffle.

[0010] As a further solution of the utility model: the driving motor drives the discharge baffle to rotate via a rotating shaft.

[0011] As a further solution of the present invention: the partition is fixedly connected to the first water inlet bin and the second water inlet bin, and a water inlet pipe is provided through the side surface of the first water inlet bin.

[0012] As a further solution of the utility model: the drainage pipe is connected with the drainage bin.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] When the discharge baffle rotates as a whole, the pull rope is pulled downward to pull the scraper plate downward inside the side limit groove, so that the scraper plate as a whole squeezes the spring downward to deform, and the scraper plate will scrape the sludge adhered to the inclined surface below downward.

[0015] The sludge accumulated on the side baffles will also flow into the sludge storage bin after tilting. After the sludge discharge is completed, the discharge baffle is controlled to rotate upward so that the upper end of the discharge baffle is stuck in the middle baffle, which can ensure the subsequent sedimentation of sewage.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-5 As shown, the present embodiment provides a sewage treatment mud discharge device, including a sedimentation tank 1, a sedimentation bin 4 is arranged in the middle of the sedimentation tank 1, a mud storage bin 401 is installed on the lower surface of the sedimentation bin 4, a middle baffle 403 is installed above the mud storage bin 401, and discharge baffles 402 are symmetrically installed on both sides below the middle baffle 403, and the discharge baffles 402 are snap-connected with the middle baffle 403, and side baffles 404 are arranged above the two discharge baffles 402 on the side away from the middle baffle 403, and scrapers 405 are arranged on the left and right ends of the inner side of the sedimentation bin 4, and side limits are arranged on the inner wall of the sedimentation bin 4 on both side sections of the scraper 405. The scraper plate 405 is slidably connected to the side limit groove 406, and a spring 407 is installed inside the side limit groove 406 on the lower surface of the scraper plate 405. A pull rope 408 is connected between the scraper plate 405 and the discharge baffle 402, and the pull rope 408 is fixedly connected to the scraper plate 405 and the discharge baffle 402. A limit ring 409 is installed on the outside of the pull rope 408 above the side baffle 404. A drive motor 7 is installed on the side surface of the sedimentation tank 1 at one end of the discharge baffle 402 through a rotating shaft. The drive motor 7 drives the discharge baffle 402 to rotate through the rotating shaft, and a dispersion mechanism 6 is installed inside the sedimentation bin 4.

[0024] like Figure 2-5As shown, in the present embodiment, a water inlet mechanism is provided at the left end of the sedimentation bin 4, and the water inlet mechanism includes: a first water inlet bin 2 and a second water inlet bin 3, a water inlet pipe 8 is provided through the side surface of the first water inlet bin 2, a partition 9 is installed between the first water inlet bin 2 and the second water inlet bin 3, the partition 9 is fixedly connected to the first water inlet bin 2 and the second water inlet bin 3, a water through hole 10 is provided at the lower end of the partition 9, a return pipe 11 is connected between the upper end of the second water inlet bin 3 and the sedimentation bin 4, a drainage bin 5 is provided at the end of the sedimentation tank 1 away from the water inlet mechanism, an overflow box 502 is installed at the side of the drainage bin 5 close to the sedimentation bin 4, a drainage pipe 501 is provided inside the overflow box 502, and the drainage pipe 501 is connected with the drainage bin 5.

[0025] The working principle of the utility model is as follows: by connecting the water inlet pipe 8 to the sewage source, after the sewage is poured into the interior of the first water inlet bin 2 through the sewage, the sewage will flow into the interior of the second water inlet bin 3 through the water perforation 10 at the lower end of the partition 9, and the water level after circulation will rise and then flow into the top of the sedimentation bin 4 through the return pipe 11. After the sewage is evenly dispersed under the action of the dispersion mechanism 6 and flows into the bottom of the dispersion mechanism 6, the sludge is accumulated on the upper surface of the discharge baffle 402 as a whole. After the water level rises as a whole inside the sedimentation bin 4, the rising water will overflow into the interior of the overflow box 502, and then be introduced into the interior of the drainage bin 5 by the drainage pipe 501. The sludge is accumulated and settled on the upper surface of the discharge baffle 402 as a whole. When the thickness is determined, the discharge baffle 402 is driven by the driving motor 7 to rotate the rotating shaft, thereby opening the passage between the sludge bin 401 and the sedimentation tank 1. When the discharge baffle 402 rotates as a whole, the pull rope 408 is pulled downward to pull the scraper plate 405 downward inside the side limit groove 406, so that the scraper plate 405 squeezes the spring 407 downward as a whole to deform, and the scraper plate 405 will scrape the sludge adhered to the inclined surface below downward, and the sludge accumulated on the side baffle 404 will also flow into the sludge bin 401 after tilting. After the sludge discharge is completed, the discharge baffle 402 is controlled to rotate upward so that the upper end position of the discharge baffle 402 is stuck in the middle baffle 403.
