Description

Technical Field

[0001] The utility model belongs to the technical field of rural sewage treatment, and particularly relates to a water supply and drainage clarifier. Background Technique

[0002] The medium that plays the role of intercepting and separating impurity particles in the clarifier is suspended sludge. In the clarifier, the sediment is lifted and kept in a uniformly distributed suspended state to form a high-concentration stable active sludge layer in the pool, which is a common treatment structure in current rural sewage treatment.

[0003] The existing publicly disclosed patent (publication number: CN 211706146 U) discloses a water supply and drainage clarifier, the structure of which includes a clarifier, an outlet hole, a support column, a chassis, a sewage discharge port, a conical pool, a connecting ring, and an inlet hole. The right side of the outlet hole is embedded and installed on the left side of the clarifier. For the water supply and drainage clarifier of the utility model, sewage is introduced into the interior of the clarifier through the inlet hole, and the sewage is treated by the treatment system inside the clarifier. After the treatment is completed, the waste is discharged through the sewage discharge port, and the filtered water quality is discharged through the outlet hole. The sealing block is squeezed by the pressure of the water flow, so that the sealing block squeezes the return spring upward, driving the telescopic rod to move upward. The balance rod below plays a role of balancing and limiting to prevent the sealing block from shifting when moving upward. The sealing ring plays a sealing role to prevent a gap between the sealing block and the outlet, so as to effectively prevent backflow from occurring when discharging water quality, resulting in the phenomenon of repeated filtration.

[0004] In the above water supply and drainage clarifier, during the treatment process of waste items, there is a lack of an auxiliary inner wall cleaning structure, resulting in sticky impurities being adsorbed on the pool wall. After long-term accumulation, the storage space in the pool will be reduced, and the above-mentioned waste discharge method is prone to blockage. Therefore, we provide a water supply and drainage clarifier to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a water supply and drainage clarifier, which solves the problems of incomplete sewage discharge and easy blockage during sewage discharge of the existing clarifier by setting a cleaning component to assist the sewage discharge work of the clarifier.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a water supply and drainage clarifier, which comprises a clarifier body and a cleaning component arranged inside the clarifier body; the clarifier body includes a sedimentation tank, a clear water tank arranged above the sedimentation tank, a sewage outlet opened on the periphery of the sedimentation tank, a frame arranged outside the sewage outlet, a cover plate matched with the sewage outlet, a sewage storage bin fixed at the bottom of the frame, a conduit dispersedly arranged on the periphery of the clear water tank, a conversion pipe connected to the outer end of the conduit, and a drain pipe connected to the middle of the outer arc surface of the conversion pipe; the cleaning component includes a shaft member movably arranged at the bottom of the sedimentation tank, scraping rods symmetrically fixed on the periphery of the shaft member, and a mixing plate fixed to the shaft member through a connecting plate.

[0008] The utility model is further arranged such that an end cover is arranged on the top of the clear water tank, and a water inlet pipe is arranged in the middle of the end cover.

[0009] The utility model is further arranged such that the inner side of the cover plate is of an arc structure, and the telescopic end of a telescopic rod is connected to the outer side of the cover plate, and the telescopic rod is fixed to the outer side of the frame.

[0010] The utility model is further arranged such that a guide rail is fixed on the upper side surface of the frame, a roller is arranged in cooperation with the guide rail, and a shaft rod is fixed to the roller, and the shaft rod is movably arranged on the upper part of the cover plate.

[0011] The utility model is further arranged such that the frame is fixed on the periphery of the sedimentation tank, and a sewage storage bin is fixed at the bottom of the frame.

[0012] The utility model is further arranged such that a positioning plate is fixed on the lower side surface of the sedimentation tank, and a motor is embedded in the lower part of the sedimentation tank, and an output shaft of the motor is connected to the shaft member.

[0014] The utility model has the following beneficial effects:

[0015] 1. By arranging a plurality of conduits to divert and export the suspension in the clear water tank, the flow rate is reduced, the flow rate is increased, the influence on the sludge deposited at the bottom of the sedimentation tank is effectively reduced.

The utility model cleans the sludge inside the sedimentation tank by setting a cleaning component, and stirs the sludge with a rotating mixing plate, so that the sludge continuously rotates centrifugally in the sedimentation tank. When it moves to the sewage outlet, it is discharged from the sewage outlet due to its own centrifugal motion. At the same time, the rotating mixing plate and the side wall of the scraper rod continuously contact the inner wall of the sedimentation tank to clean the inner wall of the sedimentation tank, thereby preventing the sludge from being adsorbed inside the sedimentation tank and causing a reduction in its storage volume.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. Specific Embodiment 1

[0027] Please refer to Figures 1-4 , the present invention is a water supply and drainage clarifying tank, including a clarifying tank body 1; the clarifying tank body 1 includes a sedimentation tank 11, a clear water tank 13 arranged on the upper part of the sedimentation tank 11, a sewage discharge port 17 opened on the periphery of the sedimentation tank 11, a frame 16 arranged outside the sewage discharge port 17, a cover plate 18 matched with the sewage discharge port 17, a sewage storage bin 110 fixed at the bottom of the frame 16, guide pipes 111 dispersedly arranged on the periphery of the clear water tank 13, a conversion pipe 112 connected to the outer ends of the guide pipes 111, and a drain pipe 113 connected to the middle of the outer arc surface of the conversion pipe 112.

[0028] Specifically, in the water supply and drainage clarifying tank involved in the present application, the clarifying tank body 1 is a sedimentation and static structure for sewage. The cavity structure formed by setting the sedimentation tank 11 and the clear water tank 13 is used to store and place the sewage. The sewage discharge port 17 discharges the settled sludge. A plurality of guide pipes 111 lead out the suspension in the clear water tank 13, and are introduced into the next process through the conversion pipe 112 and the drain pipe 113. The plurality of guide pipes 111 divert and lead out the suspension in the clear water tank 13, reducing the flow rate and increasing the flow rate, effectively reducing the impact on the sludge deposited at the bottom of the sedimentation tank 11. After the sludge is led out through the sewage discharge port 17, under the action of gravity, it enters the sewage storage bin 110 along the frame 16 and enters the external collection structure from the sewage storage bin 110, avoiding blockage during the sludge discharge process. The cover plate 18 matched with the sewage discharge port 17 is controlled by the telescopic rod 19, and the opening and closing control of the sewage discharge port 17 is relatively simple.

[0029] Furthermore, an end cover 14 is arranged on the top of the clear water tank 13, and a water inlet pipe 15 is arranged in the middle of the end cover 14.

[0030] Specifically, the end cover 14 is used for covering the upper part of the clear water tank 13, so that the internal cavities of the sedimentation tank 11 and the clear water tank 13 are closed chambers. When treating sewage, external sewage is transported to the water inlet pipe 15 through a conveying pipe, and is introduced into the clear water tank 13 through the water inlet pipe 15 and stored in the internal cavities of the sedimentation tank 11 and the clear water tank 13.

[0031] The inner side of the cover plate 18 is an arc structure, and the outer side of the cover plate 18 is connected to the telescopic end of a telescopic rod 19, and the telescopic rod 19 is fixed to the outer side of the frame 16; a guide rail 114 is fixed to the upper side surface of the frame 16, the guide rail 114 is provided with a roller 115 in a matching manner, and a shaft rod is fixed to the roller 115, and the shaft rod is movably arranged on the upper part of the cover plate 18.

[0032] Specifically, the arc structure on the inner side of the cover plate 18 is matched with the arc-shaped sewage discharge port 17 opened on the side surface of the sedimentation tank 11 for sealing and covering the sewage discharge port 17. When the telescopic rod 19 is started, the telescopic end of the telescopic rod 19 drives the cover plate 18 to move inside the frame 16 to realize the opening and closing control of the sewage discharge port 17. During the movement of the cover plate 18, the shaft rod movably embedded in the upper part of the cover plate 18 rotates under the action of the roller 115, and the movement of the roller 115 relative to the guide rail 114 is used to balance the linear movement of the cover plate 18.

[0033] The frame 16 is fixed to the periphery of the sedimentation tank 11, and a sewage discharge bin 110 is fixed to the bottom of the frame 16; a positioning plate 12 is fixed to the lower side surface of the sedimentation tank 11, and a motor is embedded in the lower part of the sedimentation tank 11, and the output shaft of the motor is connected to the shaft member 21.

[0034] Specifically, a partition layer is arranged at the bottom of the sedimentation tank 11 for installing the motor, and the positioning plate 12 fixed to the bottom of the sedimentation tank 11 is used for the fixed installation of the clarification tank body 1 and the outside.

[0035] The operation process of this embodiment is as follows: when the clarification tank body 1 is in use, first, sewage is discharged into the inner chambers of the sedimentation tank 11 and the clear water tank 13 through the water inlet pipe 15, and after standing and sedimenting for a period of time, components such as sludge in the sewage are deposited in the sedimentation tank 11, and the liquid in the clear water tank 13 is a suspension. Start the external pump body structure to extract the suspension. The suspension is discharged through a number of conduits 111 and introduced into the next process through the conversion pipe 112 and the drain pipe 113. When cleaning the sludge, start the telescopic rod 19, and the telescopic end of the telescopic rod 19 drives the cover plate 18 to move inside the frame 16 and gradually move away from the sewage discharge port 17, so that the sewage discharge port 17 is in a fully open state. After the sludge is discharged from the sewage discharge port 17, under the action of gravity, it enters the sewage discharge bin 110 along the frame 16 and then enters the external collection structure from the sewage discharge bin 110 to complete the clarification treatment of the sewage. Specific Embodiment Two

[0037] Please refer to Figure 3Based on the specific embodiment 1, a water supply and drainage clarifier includes a cleaning assembly 2 arranged inside the clarifier body 1, and the cleaning assembly 2 includes a shaft 21 movably arranged at the bottom of the sedimentation tank 11, a scraper rod 23 symmetrically fixed to the side of the shaft 21, and a mixing plate 22 fixed to the shaft 21 via a connecting plate 24.

[0038] Specifically, in the water supply and drainage clarifier involved in the present application, the cleaning component 2 is used to clean the sludge inside the sedimentation tank 11. By setting a rotating mixing plate 22 to stir the sludge, the sludge is continuously centrifugally rotated in the sedimentation tank 11. When it moves to the sewage outlet 17, it is discharged from the sewage outlet 17 due to its own centrifugal movement. At the same time, the rotating mixing plate 22 and the side wall of the scraper rod 23 are continuously in contact with the inner wall of the sedimentation tank 11 to clean the inner wall of the sedimentation tank 11, thereby preventing the sludge from being adsorbed inside the sedimentation tank 11 and causing its storage volume to be reduced.

[0039] Furthermore, the outer end of the scraper rod 23 is in contact with the inner wall of the sedimentation tank 11, the mixing plate 22 is a fan-shaped twisted structure, and the bottom of the mixing plate 22 is in contact with the bottom of the internal cavity of the sedimentation tank 11, and the side of the mixing plate 22 is in contact with the side wall of the sedimentation tank 11.

[0040] Specifically, the scraper rod 23 is mainly used to clean the inner wall of the sedimentation tank 11, and the mixing plate 22 is mainly used to drive the centrifugal movement of the sludge. The height of the scraper rod 23 is the same as that of the sedimentation tank 11, and the mixing plate 22 is located at the bottom of the sedimentation tank 11, so as to prevent the mixing plate 22 with a larger area from introducing the sludge into the clear water tank 13. The fan-shaped twisted structure of the mixing plate 22 is subject to less damping during movement, so as to prevent its plate surface from breaking when it is subjected to greater resistance. The scraper rod 23 and the mixing plate 22 are staggered.

[0041] The operation process of this embodiment is as follows: when the cleaning component 2 is working, the motor is started, and the output shaft of the motor drives the rotation of the shaft 21, so that the mixing plate 22 and the scraper rod 23 fixed to the shaft 21 rotate synchronously. During the rotation of the mixing plate 22, the sludge is continuously centrifugally rotated in the sedimentation tank 11. When it moves to the sewage outlet 17, it is discharged from the sewage outlet 17 due to its own centrifugal movement, and the scraper rod 23 continuously cleans the inner wall of the sedimentation tank 11 when rotating, completing the sludge discharge and cleaning work after the sewage clarification treatment.
