Description

Technical Field

[0001] This utility model relates to the field of wastewater sedimentation technology, specifically a wastewater sedimentation and filtration device with deep treatment function. Background Technology

[0002] With water resources becoming increasingly scarce, coupled with the indiscriminate discharge of wastewater from industrial and domestic water use, the pollution level of water resources is increasing, and the ecological environment is being damaged. Nowadays, every place has wastewater treatment plants to carry out sewage treatment such as sedimentation and filtration. Wastewater filtration is used to remove internal impurities from polluted water resources, thereby purifying the wastewater. Sedimentation can be used to allow internal impurities in the wastewater to settle to the bottom for treatment.

[0003] In existing technologies, commonly used wastewater sedimentation and filtration devices typically involve directly adding flocculants to the wastewater to induce a sedimentation reaction during the sedimentation process.

[0004] Because wastewater has varying solid-liquid ratios, when the wastewater contains a high proportion of water, a large amount of flocculant needs to be added. This not only wastes the flocculant but also fails to achieve a good sedimentation effect. If the wastewater undergoes preliminary flocculation and sedimentation first, separating the initial precipitate from the water, and then flocculant is added to the sludge (which contains less water) for further sedimentation, the water ratio is reduced, inevitably improving the wastewater sedimentation treatment effect. Therefore, we propose a wastewater sedimentation and filtration device with advanced treatment capabilities. Summary of the Invention

A suction pipe 6 is arranged on one side of both the pretreatment tank 1 and the supernatant tank 3, and the suction pipe 6 is used at least to extract the supernatant above the interior of the pretreatment tank 1 and the supernatant tank 3. An opening and closing mechanism 7 is arranged below the pretreatment tank 1, and the opening and closing mechanism 7 is used at least to open and close the discharge port at the bottom of the pretreatment tank 1.

[0029] In this embodiment, the system includes: a pretreatment tank 1; a sewage sedimentation tank 2 is provided below the pretreatment tank 1, and a supernatant tank 3 is provided on one side below the pretreatment tank 1. The pretreatment tank 1 can initially separate the sewage and allow it to flow into the sewage sedimentation tank 2 and the supernatant tank 3 for further deep treatment.

[0030] In this embodiment, a support frame 4 is provided between the pretreatment tank 1 and the sewage sedimentation tank 2. The support frame 4 is used for the fixed installation of the pretreatment tank 1 on the sewage sedimentation tank 2. The support frame 4 includes several vertical plates 41 fixed to the outer walls of both sides of the pretreatment tank 1 and the sewage sedimentation tank 2.

A sliding saddle 43 is provided at the bottom of the vertical plate 41, and several guide wheels 44 are provided at the top inside the sliding saddle 43. Guide rails 45 are provided on both outer walls of the sedimentation tank 2 and the supernatant tank 3, and the sliding saddle 43 is slidably connected to the guide rails 45. When it is necessary to clean the sludge inside the sedimentation tank 2, the operator can slide the sliding saddle 43 and the guide wheel 44 on the guide rails 45 to move the pretreatment tank 1 away from the top of the sedimentation tank 2, so that the pretreatment tank 1 is located above the supernatant tank 3, so as to facilitate the cleaning of the sludge inside the sedimentation tank 2. At the same time, a suction pipe 6 is also provided on one side of the sedimentation tank 2, which can extract the supernatant inside.

[0031] In this embodiment, a feeding assembly 5 is fixedly installed on one side of the sewage sedimentation tank 2. The feeding assembly 5 is used to add flocculant into the pretreatment tank 1, the sewage sedimentation tank 2, and the supernatant tank 3. The feeding assembly 5 includes a storage tank 51 fixed to the outer wall of one side of the sewage sedimentation tank 2. The storage tank 51 is used to store flocculant.

The flocculant is used in a reasonable way, thereby reducing the amount of flocculant used and achieving a good effect of separate sedimentation and filtration of sewage.

[0032] In this embodiment, a suction pipe 6 is provided on one side of both the pretreatment tank 1 and the supernatant tank 3. The suction pipe 6 is used at least to extract the supernatant from the upper part of the pretreatment tank 1 and the supernatant tank 3. The suction pipe 6 includes a mounting bracket 64 fixed to the outer wall of one side of the pretreatment tank 1 or the supernatant tank 3, and a restraining sleeve 63 is provided on the mounting bracket 64.

When the operator is suctioning the supernatant in the pretreatment tank 1, the supernatant tank 3, and the sewage sedimentation tank 2, the operator starts the suction pump on the guide pipe 61 (not shown in the figure), thereby using the guide pipe 61 and the water suction pipe 62 to suction the supernatant. While suctioning the supernatant, the operator can start the forward and reverse motor 67, using the gear 66 to drive the toothed plate 65 to move up and down, so that the toothed plate 65 drives the guide pipe 61 to move up and down inside the restraint sleeve 63, thereby adjusting the depth of the water suction pipe 62 inside the tank, so as to achieve better and more complete suction treatment of the supernatant and facilitate better collection of sludge.

[0033] In this embodiment, an opening and closing mechanism 7 is provided below the pretreatment tank 1, and the opening and closing mechanism 7 is used at least to open and close the discharge port at the bottom of the pretreatment tank 1. After the sewage enters the interior of the pretreatment tank 1, after a period of initial sedimentation inside the pretreatment tank 1, when a portion of supernatant appears at the top of the interior of the pretreatment tank 1, the incompletely settled supernatant is pumped to the interior of the supernatant tank 3 for further sedimentation treatment using the suction pipe 6. Then, the opening and closing mechanism 7 is activated to allow the sewage and sludge inside the pretreatment tank 1 to enter the interior of the sewage sedimentation tank 2 together. The opening and closing mechanism 7 includes a discharge hole 71 on the bottom outer wall of the pretreatment box 1. The two discharge holes 71 are symmetrically distributed.

Specifically, when the motor 73 is started, the stator of the motor 73 is the spindle. After the motor is started, the outside of the motor rotates synchronously along the spindle with the outer cover 74 and the sealing plate 72, thereby realizing the overlap and separation of the sealing plate 72 and the discharge hole 71, so as to realize the opening and closing of the bottom of the pretreatment box 1.
