Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a water purification pool for circulating sewage treatment. Background Art

[0002] Sewage treatment is required for both sewage discharge and recycling. The sedimentation tank can settle the sewage. The sludge and debris in the sewage are precipitated in the sedimentation chamber and the discharge port. The precipitated sludge and debris are easy to aggregate and harden, which can easily cause blockage of the sedimentation chamber and the discharge port. Over time, it is easy to ferment and produce methane, carbon dioxide and a small amount of hydrogen sulfide and other gases.

[0003] In the prior art, there is a grading filtration and sedimentation treatment tank for mineral washing wastewater with publication number: CN205127550U, which includes: a tank body, an inlet pipe, a coarse slag tank, a coarse slag grading gate, a fine slag tank, a fine slag grading gate, a sludge tank, a sludge filtering gate, a clean water tank, an outlet pipe, a sludge discharge pipe, a plug, and an inclined bracket. The tank body is placed in the inclined bracket, and the inlet pipe is placed on the upper side of the tank body at the higher end of the inclined bracket, and the outlet pipe is placed on the lower side of the tank body at the lower end of the inclined bracket. The tank body is sequentially provided with a coarse slag grading gate, a fine slag grading gate, and a sludge filtering gate from one end of the inlet pipe, thereby dividing the tank body into a coarse slag tank, a fine slag tank, a sludge tank, and a clean water tank. The bottoms of the coarse slag tank, the fine slag tank, and the sludge tank are V-shaped and are respectively provided with sludge discharge pipes, which are closed by plugs. The sludge and debris in the sewage settle in the tank body. The sludge and debris settle to the bottom of the coarse slag tank, fine slag tank and mineral mud tank, where they are easily compacted, causing the sludge discharge pipe to be blocked, and the compacted debris cannot be cleaned.

[0004] Another example is the publication number: CN217988644U, a water purification pool based on circulating sewage treatment, including a water purification pool body and a drain pipe, the left side of the bottom of the water purification pool body is fixedly connected to the surface of the drain pipe, the top of the drain pipe is provided with a fixed groove, the internal thread of the fixed groove is connected to a limit block, the top of the limit block is fixedly connected to a filter ring, the top of the filter ring is fixedly connected to a connection anti-blocking component, the left side of the top of the water purification pool body is provided with a connection transmission component, and the left side of the water purification pool body is fixedly connected to a control box. Although the equipment can stir the impurities outside the filter ring, it cannot remove impurities that are large particles that cannot pass through the filter ring. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0019] like Figure 1 As shown, the embodiment of the water purification pool for circulating sewage treatment includes a pool body 1, an inlet pipe 2 at the upper left side of the pool body 1, a drain pipe 3 at the lower right side of the pool body 1, filter plates 4 installed at equal intervals in the pool body 1, a sedimentation chamber 5 at the bottom of the pool body 1, a sewage outlet 6 and a screw conveyor 7 at the bottom of the sedimentation chamber 5, and the bottom discharge end of the sewage outlet 6 is connected to the screw conveyor 7, and the screw conveyor 7 is used to transport sludge and debris. It also includes a water pump 8, the water inlet end of the water pump 8 is connected to the middle of the inner cavity of the pool body 1 through a hose, and the water outlet end of the water pump 8 is installed with a water outlet pipe 9, and a plurality of branch pipes 10 are installed on the water outlet pipe 9. The water outlet pipe 9 is connected with the sedimentation chamber 5 and the sewage outlet 6 through the branch pipe 10. The water pump 8 extracts water from the inner cavity of the pool body 1, and flushes the sedimentation chamber 5 and the sewage outlet 6 through the water outlet pipe 9 and the branch pipe 10 to avoid blockage of the sewage outlet 6 and remove the sludge and debris settled in the sedimentation chamber 5. A switch valve 11 is installed on the branch pipe 10. The opening sequence of the switch valve 11 controls the flushing sequence of the sedimentation chamber 5 and the sewage outlet 6.

[0020] Furthermore, a plurality of filter plates 4 are provided, and the plurality of filter plates 4 divide the inner cavity of the tank body 1 into a plurality of cavities, and the sedimentation chamber 5 and the sewage outlet 6 are both correspondingly arranged at the bottom of the cavity, so that the sewage can be graded and settled.

[0021] Furthermore, the sedimentation chamber 5 is a funnel structure, which can enrich the settled sludge and debris.

[0022] Working principle: The sewage entering the tank body 1 through the water inlet pipe 2 is left to settle inside the tank body 1. The sludge and debris enter the sewage outlet 6 and the sedimentation chamber 5 after sedimentation. When the amount of sludge and debris settled is large and needs to be cleaned, the water inlet pipe 2 is closed, and the water pump 8 extracts water from the middle of the inner cavity of the tank body 1 through the outlet pipe 9 and the branch pipe 10 to slowly flush the sedimentation chamber 5 and the sewage outlet 6. The opening order of the switch valve 11 is to open it from bottom to top in sequence. The sediment inside the sewage outlet 6 is mixed and flushed with water and then enters the screw conveyor 7 for transportation. After the sediment inside the sewage outlet 6 is flushed to a certain extent, the switch valve 11 at the upper position is opened in sequence, so as to flush and discharge the sediment in the sedimentation chamber 5 and the sewage outlet 6.
