Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a sewage sedimentation device. Background Technology

[0002] Wastewater sedimentation units are key facilities used to treat suspended solids in wastewater. They use gravity to separate heavier particles from the wastewater, causing them to settle to the bottom of the container and form sludge, while the upper layer consists of relatively clear water that can be further treated or discharged. Wastewater sedimentation units are an important part of the wastewater treatment process and play a vital role in reducing environmental pollution and protecting water resources.

[0003] Chinese utility model patent publication number CN 220294175 U discloses a sewage sedimentation device. In practical applications, it has been found that this device cannot achieve effective zoned sedimentation of particulate matter in the water, resulting in significant disturbance to the water body inside the device caused by the incoming sewage. Furthermore, the relatively short sedimentation path of the particulate matter not only limits the sedimentation efficiency but also fails to meet the requirements for continuous sewage sedimentation treatment, thus affecting the overall sewage treatment effect and quality. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a sewage sedimentation device.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A wastewater sedimentation device includes a cylindrical body open at the top and a frame supporting the cylindrical body; a sludge storage section in the shape of an inverted frustum is provided at the lower part of the cylindrical body, and a drain pipe with a drain valve is provided at the lower end of the sludge storage section; a guide tube open at the lower end is provided inside the cylindrical body, and the lower end of the guide tube is connected to the inner wall of the sludge storage section through a support; the upper end of the guide tube is lower than the upper end of the cylindrical body, and an overflow pipe is provided at the upper part of the guide tube, extending out of the cylindrical body; a diversion channel is provided at the upper end of the guide tube, and several diversion ports are evenly distributed at the upper edge of the outer wall of the diversion channel; a mixing cylinder open at the upper end is provided in the middle of the diversion channel, and an inlet pipe and a flocculant addition pipe are provided at the lower part of the mixing cylinder; an orifice plate is provided inside the mixing cylinder.

[0007] Preferably, the sludge storage section is provided with an observation window.

[0008] Preferably, the lower end of the guide tube is provided with a frustoconical guide shroud.

[0009] Preferably, the lower end of the guide tube is provided with an inverted frustum-shaped guide shroud.

[0010] Preferably, the diversion port is triangular.

[0011] Preferably, the liquid inlet pipe and the flocculant addition pipe are symmetrically arranged on the outer wall of the mixing cylinder.

[0012] Preferably, the diversion channel is cylindrical.

[0013] The above technical solution has the following advantages:

[0014] This invention incorporates a guide tube within the casing. After the incoming wastewater and flocculant are thoroughly mixed in the mixing tube, the wastewater is then evenly distributed and diverted through a distribution channel, significantly reducing the impact force upon entering the casing. Particulate matter in the wastewater then undergoes an initial settling process along the outer surface of the guide tube, eventually reaching the bottom of the casing. Simultaneously, the clearer water obtained from the initial settling enters the interior of the guide tube through the space below, undergoing further secondary separation and settling. Finally, the clear water, after two settling processes, is discharged through an overflow pipe at the top of the guide tube. This invention achieves effective zoned settling of the water flow by incorporating a guide tube within the casing, ensuring a longer settling path for particles, thus making the separation and settling process more thorough and efficient. Furthermore, this design supports continuous wastewater treatment, improving the overall efficiency and quality of wastewater treatment. Attached Figure Description

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] As shown in the attached figure, a wastewater sedimentation device includes a cylindrical body 1 with an open upper end and a frame 2 supporting the cylindrical body 1; a sludge storage section 3 in the shape of an inverted frustum is provided at the lower part of the cylindrical body 1, and a sewage pipe 4 is provided at the lower end of the sludge storage section 3, with a sewage valve 5 provided on the sewage pipe 4; a guide tube 6 with an open lower end is provided inside the cylindrical body 1, and the lower end of the guide tube 6 is connected to the inner wall of the sludge storage section 3 through a bracket 7; the upper end of the guide tube 6 is lower than the upper end of the cylindrical body 1, and an overflow pipe 8 is provided at the upper part of the guide tube 6, extending out of the cylindrical body 1; a diversion channel 9 is provided at the upper end of the guide tube 6, and several diversion ports 10 are evenly distributed at the upper edge of the outer wall of the diversion channel 9; a mixing tube 11 with an open upper end is provided in the middle of the diversion channel 9, and an inlet pipe 12 and a flocculant addition pipe 13 are provided at the lower part of the mixing tube 11; and an orifice plate 14 is provided inside the mixing tube 11.

[0025] As a further improvement to this embodiment, the sludge storage section 3 is provided with an observation window 15, which facilitates the observation of the settling of particles in the sludge storage section 3, so as to facilitate the operator to discharge the settling in the sludge storage section 3.

[0026] As a further improvement in this embodiment, the lower end of the guide tube 6 is provided with a frustum-shaped guide hood 16, which can guide the settled particles to the wall of the sludge storage section 3 so that the particles can settle better.

[0027] As a further improved technical solution in this embodiment, the lower end of the guide tube 6 is provided with an inverted frustum-shaped guide hood 17, which can further guide and settle particulate matter in sewage, thereby improving the sewage sedimentation effect.

[0028] As a further improvement to this embodiment, the diversion port 10 is triangular, but it can obviously also be U-shaped or the like.

[0029] As a further improvement to this embodiment, the liquid inlet pipe 12 and the flocculant addition pipe 13 are symmetrically arranged on the outer wall of the mixing cylinder 11, which can further improve the mixing effect.

[0030] As a further improvement to this embodiment, the diversion channel 9 is cylindrical, but obviously it can be in other applicable shapes.

[0031] In use, the wastewater and flocculant are first thoroughly mixed in the mixing cylinder 11, and then enter the diversion tank 9 from the top of the mixing cylinder 11. The wastewater is then evenly distributed and diverted through the diversion tank 9, significantly reducing the impact force upon entering the cylinder 1. Particulate matter in the wastewater then undergoes an initial settling process along the outer surface of the guide cylinder 6, eventually reaching the bottom of the cylinder 1. Simultaneously, the clearer water obtained from the initial settling enters the interior of the guide cylinder 6 through the space at the bottom for further secondary settling. Finally, the clear water after two settling processes is discharged through the overflow pipe 8 above the guide cylinder 6. This invention achieves effective zoned settling of the water flow by setting the guide cylinder 6 inside the cylinder 1, ensuring that particulate matter has a longer settling path, thus making the separation and settling process more thorough and efficient.
