Problems solved by technology

[0005] Chinese patent (notification number: CN205667732 U) discloses a sedimentation device for sewage treatment. A reflective plate is set under the liquid inlet pipe in the tank. The reflective plate includes a plurality of inclined plates arranged obliquely. After entering the tank, it hits the reflector and moves along the inclined plates under the action of the reflector, but it still cannot completely separate the settled solids, and the suspended solids at the bottom are still raised by the water flow, which is not conducive to use

Embodiment 1

[0025] Please refer to the figure, in an embodiment of the present invention, a settling tank for sewage treatment that separates sediments in time includes a settling tank shell 1, a water inlet 2, a first inclined plate 3, a second inclined plate 4, a bottom plate 6, a lifting Plate 8 and lifting drive device 9; a water inlet 2 is provided on the top right end of the sedimentation tank housing 1, and sewage is sent into the sedimentation tank housing 1 from the water inlet 2, and the first inclined plate 3 and the second inclined plate The plates 4 are arranged symmetrically, the lower ends of the first inclined plate 3 and the second inclined plate 4 are fixedly connected by a horizontal bottom plate 6, and an upwardly opening groove body 5 is formed by the first inclined plate 3, the second inclined plate 4, and the bottom plate 6. Several bodies 5 are provided in the sedimentation tank shell 1, and are sealed and connected horizontally in sequence. The first inclined plate...

Embodiment 2

[0030] On the basis of embodiment 1, the inclined dispersion plate 18 that is provided with below the described water inlet 2, the right end of the inclined dispersion plate 18 is higher than the left end, makes the water that falls on the inclined dispersion plate 18 flow to the left; The upper surface of the plate 18 is provided with several diversion grooves 24 along the left and right directions, and the bottom of the diversion grooves 24 is uniformly provided with several water holes 25 penetrating through the inclined dispersion plate 18, and the water flowing in the diversion grooves 24 passes through The water hole 25 falls to the bottom; the top between the two adjacent diversion grooves 24 is provided with an inclined diversion slope 26, and is inclined to the diversion grooves 24 on both sides respectively, so as to facilitate the water flow to fall, and avoid the inclination of the diffuser plate. 18 residual sewage.

Embodiment 3

[0032] On the basis of Embodiment 2, the end of the drain pipe 12 is connected with a filter device 14, and the built-in filter screen is used to filter the discharged water. The filter device 14 is connected with a circulation pipe 15, and the other end of the circulation pipe 15 is connected to the into the sedimentation tank housing 1, and the nozzle is located below the water inlet 2, a circulation pump 16 is installed on the circulation pipe 15, and the water filtered in the filter device 14 is sent into the sedimentation tank housing 1 again, and the filter device The bottom of 14 is provided with blowdown outlet 17, is convenient to cleaning up the impurity that filters.

Abstract

The invention relates to the field of environment protection, and particularly discloses a settling tank capable of separating sediments timely for sewage treatment. The settling tank comprises a settling tank shell, a water inlet, first inclined plates, second inclined plates, bottom plates, a lifting plate and a lifting driving device; the lower ends of each first inclined plate and the corresponding second inclined plate are fixedly connected with each other through the corresponding horizontal bottom plate; a sealing cavity is formed above the lifting plate; a plurality of vertical separating sealing plates are fixed to the upper surface of the lifting plate; each separating sealing plate corresponds to the corresponding bottom plate, and each separating sealing plate penetrates through the corresponding bottom plate upwards; the two sides of each sealing plate are sealed with the corresponding bottom plate; a collecting cavity for communicating the left side and the right side isformed in each separating sealing plate. According to the settling tank capable of separating sediments timely for the sewage treatment, solid sediments are collected in the collecting cavities, movedownwards along with the separating sealing plate and are separated from the collecting cavities from the lower parts of the bottom plates through the arranged separating sealing plates and the collecting cavities which are formed in the separating sealing plates, so that settled solid sediments can be separated timely.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a settling tank for sewage treatment which can separate sediments in time. Background technique [0002] As the concepts of low-carbon, green, and environmental protection become more and more popular, more and more companies are pursuing production interests while also paying attention to environmental problems caused by production. In industrial production activities, sewage treatment and discharge It has a great impact on the local ecological environment, especially the water source. In recent years, there have been many major incidents that have caused adverse effects due to improper sewage treatment and discharge. Therefore, the safety issues caused by sewage treatment and discharge need to be resolved urgently. [0003] In the process of sewage treatment, the separation of wastewater and waste residue is a basic step, usually as the first step in sewage treatment, it...
