Description

Technical Field

[0001] The utility model relates to the technical field of wastewater sedimentation, in particular to a wastewater sedimentation tank with a stirring structure. Background Art

[0002] During the sewage treatment process, it is often necessary to carry out sedimentation treatment on the sewage to remove suspended matter in the sewage. When the sewage is settling, the sewage needs to be introduced into the sedimentation tank first, and then the suspended matter in the sewage is settled to the bottom of the sedimentation tank through natural sedimentation or coagulation sedimentation. When the sediment in the sedimentation tank accumulates to a certain extent, the sediment in the sedimentation tank needs to be cleaned.

[0003] The utility model patent with the authorization announcement number CN215275902U discloses a sewage sedimentation tank, which includes a sedimentation tank body, a partition is fixedly arranged in the sedimentation tank body, a material drop opening is provided on the partition, a sealing plate is slidably arranged on the partition, a connecting groove for connecting the material drop opening is provided on the sealing plate, a driving member for driving the sealing plate to slide is provided on the sedimentation tank body, and a silt discharge opening is provided on the side wall of the sedimentation tank body. The application has the effect that when the sediment in the sedimentation tank body is cleaned, the sedimentation tank body can continue to perform sedimentation operations.

[0004] Although the above utility model can conveniently clean the sedimentation tank, it is sometimes necessary to add flocculants to assist in the sedimentation work. The flocculants can combine with the impurities in the water to accelerate the sedimentation speed, but the flocculants are piled up after being added and cannot effectively contact the impurities in the water. In view of this, we propose a wastewater sedimentation tank with a stirring structure. Utility Model Content

[0029] See also Figure 1-Figure 4 , this embodiment provides a technical solution:

[0030] A wastewater sedimentation tank with a stirring structure comprises a sedimentation tank 1, wherein sewage outlets 2 are arranged at the lower ends of the left and right surfaces of the sedimentation tank 1, observation mechanisms 3 are rotatably connected to the top ends of the front and rear surfaces of the sedimentation tank 1, a stirring mechanism 4 is rotatably connected to one side of the upper surface of the sedimentation tank 1, connection blocks 11 are welded to the left and right sides of the upper ends of the front and rear surfaces of the sedimentation tank 1, a connection hole 12 is provided on one side of the connection block 11, and connection grooves 13 are provided at both ends of the front and rear sides of the upper surface of the sedimentation tank 1. Through the above-mentioned mechanism, the flocculant put into the sedimentation tank 1 can be stirred to increase its bonding degree with the water body.

[0031] Furthermore, the observation mechanism 3 includes a connecting rod 31, connecting auxiliary blocks 32 welded to both ends of the connecting rod 31, and a connecting plate 33 welded to one side of each connecting auxiliary block 32. A support frame 34 is welded to the outside of the connecting plate 33, a limiting plate 35 is welded to the upper end of the front surface of the support frame 34, a lifting auxiliary block 36 is welded to the front end of the upper surface of the support frame 34, and an observation plate 37 is installed inside the upper surface of the support frame 34, which can conveniently detect whether the stirring mechanism 4 needs to be cleaned.

[0032] Furthermore, the stirring mechanism 4 includes a rotating plate 41, a lifting handle 44 welded to the left end of the upper surface of the rotating plate 41, and a hinged plate 48 fixedly installed on the right end of the upper surface of the rotating plate 41. The other end of the hinged plate 48 is installed on one side of the upper surface of the sedimentation tank 1. A motor 42 is installed in the middle position of the upper surface of the rotating plate 41, a feed port 43 is provided on the left side of the upper surface of the rotating plate 41, and a stirring rod 46 is rotatably connected to the middle position of the lower surface of the rotating plate 41. A plurality of stirring blades 47 are welded to the side surface of the stirring rod 46. The stirring blades 47 and the stirring rod 46 stir the water under the control of the motor 42.

[0033] In this embodiment, the left side surface of the adjacent connecting groove 13 and the right side surface of the connecting hole 12 are located in the same horizontal plane, and the connecting rod 31 is rotatably connected in the connecting hole 12, so that the observation mechanism 3 as a whole can rotate around the connecting hole 12.

[0034] In this embodiment, the cross section of the support frame 34 is L-shaped, and the observation plate 37 is made of transparent plastic, so that the user can see directly through the observation plate 37.

[0035] In this embodiment, a through hole is provided on the side surface of the lifting auxiliary block 36, and a sealing strip is attached to the lower surface of the limiting plate 35 to increase the sealing performance when the limiting plate 35 contacts the limiting groove 45. The through hole provided on the lifting auxiliary block 36 can allow a rope to pass through, and the rope can assist the observation mechanism 3 in rotating.

[0036] In this embodiment, the output shaft of the motor 42 is coaxially connected to the stirring rod 46, and the length of the stirring blade 47 is less than half of the width of the sedimentation tank 1 in a top view, ensuring that the stirring blade 47 can rotate smoothly.

[0037] In this embodiment, the outer surface of the lifting handle 44 is wrapped with a sponge pad, and a sealing plug is installed on the feed port 43 to increase the comfort of the user's grip.

[0039] In the specific use process of the wastewater sedimentation tank with a stirring structure of this embodiment, the flocculant is fed into the sedimentation tank 1 through the feed port 43, and then the motor 42 is started. The motor 42 drives the stirring blade 47 to rotate through the stirring rod 46 to stir the water body, so that the flocculant can better combine with the impurities in the water body. After stirring for a certain period of time, the motor 42 is turned off to wait for sedimentation;

[0040] When the stirring mechanism 4 needs to be cleaned, first pull up the observation mechanism 3 by the lifting auxiliary block 36 and rotate it more than 180° until the lifting auxiliary block 36 contacts the side surface of the sedimentation tank 1, then hold the lifting handle 44 to rotate the rotating plate 41 around the hinge plate 48 and lift it until the rotating plate 41 rotates 180° and contacts the upper surface of the sedimentation tank 1, so that the stirring mechanism 4 can be cleaned.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model.
