Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically to a high-efficiency sedimentation tank rotary skimming pipe slag cleaning device. Background Art

[0002] Sedimentation tanks are primarily used in sewage treatment. By using chemicals to react in the sewage, they flocculate fine suspended particles to form large alum flocs. The alum flocs fall faster than the hydraulic surface load, creating a sludge-water separation effect. However, the sewage in the sedimentation tank contains not only suspended particles but also small floating debris and duckweed that were not filtered out by the front-end treatment. Duckweed accumulates on the surface of the tank and multiplies until it covers the entire surface. This mixed with the small debris creates a poor visual impression and affects water quality. Manual removal is time-consuming, labor-intensive, and poses a safety hazard. Therefore, we propose a highly efficient sedimentation tank rotary skimmer cleaning device. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art, meet practical needs, and provide a high-efficiency sedimentation tank rotary skimming pipe slag cleaning device to solve the current technical problem of floating garbage affecting water quality.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a high-efficiency sedimentation tank rotary skimming pipe slag cleaning device, comprising a slag cleaning pipe arranged on the upper surface of the sedimentation tank, a slag inlet notch opened on the outer periphery of the slag cleaning pipe, sealing covers provided at both ends of the slag cleaning pipe, a chain transmission structure provided between one of the sealing covers and the top of the sedimentation tank, a discharge port provided at one end of the slag cleaning pipe, a cam driving structure provided on one side of the interior of the slag cleaning pipe, a connecting rod structure provided below the cam driving structure, a straight plate provided on one side of the connecting rod structure, and a plurality of paddle plates connected to the outer periphery of the straight plate.

[0005] Preferably, the sealing cover is a flared structure, the flared end of the sealing cover is fixed to the side wall of the sedimentation tank, and the contracted end of the sealing cover is fitted to the outer periphery of the slag cleaning pipe.

[0006] Preferably, the chain transmission structure includes a matching transmission chain and two sprockets, one of the transmission chains is connected to a transmission rod, and the transmission rod is fixed to the center of one end of the slag cleaning pipe, and the other transmission chain is connected to the center of a reduction motor, and the reduction motor is fixed to the top of the sedimentation tank, and a gap is opened in the corresponding sealing cover for the transmission chain to pass through.

[0007] Preferably, the discharge port is a curved structure with a circular trajectory, a discharge pipe penetrating the slag cleaning pipe is provided on one side of the discharge port, and a filter box is provided at the discharge port end of the discharge pipe.

[0008] Preferably, the cam driving structure includes a cylindrical cam and a disc that are adapted to each other, a plurality of limiting columns adapted to the cylindrical cam are installed on one side of the disc, a center rod is connected to the center of the cylindrical cam, and the center rod is fixed to the transmission rod.

[0009] Preferably, the bottom of the disc is rotatably connected to a bending plate, one side of the bending plate is connected to a fixing rod, and the end of the fixing rod is fixed to the side wall of the sedimentation tank.

[0010] Preferably, the connecting rod structure includes two bayonet pins, which are respectively connected to the bottom of the disc and the top of the straight plate. A connecting rod is provided between the two bayonet pins, and connecting rod heads with annular structures are provided at both ends of the connecting rod.

[0011] Preferably, the outer periphery of the paddle plate is matched with the inner periphery of the slag cleaning pipe, and a flow gap is provided between the bottom of the paddle plate and the inner periphery of the slag cleaning pipe.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model uses the slag inlet gap of the slag cleaning pipe and the transmission of the transmission chain and chain belt, and cooperates with the reduction motor to drive the sprocket. When the reduction motor is used, the slag cleaning pipe can swing back and forth (the swing range is about 90 degrees). When the slag inlet gap swings to be submerged in the horizontal plane, the sewage and floating garbage on the upper surface will enter. With the cooperation of the sealing cover, the discharge port, the discharge pipe and the filter box, the floating garbage is filtered, and the floating garbage in the sedimentation tank is removed, thereby solving the problem of floating garbage affecting water quality.

[0014] 2. The utility model also connects the cylindrical cam with the center rod and fixes the center rod with the transmission rod. When the slag cleaning pipe swings, the cylindrical cam can swing back and forth. Then, by the rotational connection between the disc and the curved plate and the fixation of the fixing rod to the side wall of the sedimentation tank, the fixed position of the disc in the slag cleaning pipe does not follow the swing. Therefore, when the cylindrical cam swings, the limit column drives the disc to rotate back and forth. Combined with the fixation of the connecting rod, the pin and the straight plate, the reciprocating movement of the wave plate is achieved, which can send floating garbage to the discharge port, greatly reducing the possibility of accumulation and blockage of floating garbage in the slag cleaning pipe, and further solving the problem that floating garbage inside the slag cleaning pipe may cause accumulation and blockage.

[0026] like Figures 1 to 7 As shown, the utility model relates to a high-efficiency sedimentation tank rotary skimming pipe slag cleaning device, including a slag cleaning pipe 1 arranged on the upper surface of the sedimentation tank, and sealing covers 2 are provided at both ends of the slag cleaning pipe 1. The sealing cover 2 is a flared structure, and the flared end of the sealing cover 2 is fixed to the side wall of the sedimentation tank, and the contracted end of the sealing cover 2 fits with the outer periphery of the slag cleaning pipe 1, thereby avoiding the effect of floating garbage passing through. At the same time, the flared design also plays a role in guiding floating garbage. It should be noted that the lower half of the slag cleaning pipe 1 and the sealing cover 2 are evenly in contact with the horizontal surface of the sewage in the sedimentation tank, thereby having a blocking effect on floating garbage.

[0027] In the embodiment of the present invention, in order to realize the cleaning of floating garbage, a slag inlet gap is opened on the outer periphery of the slag cleaning pipe 1, and a chain transmission structure 3 is provided between one of the sealing covers 2 and the top of the sedimentation tank. The chain transmission structure 3 includes a matching transmission chain 301 and two sprockets 302, one of the transmission chains 301 is connected to a transmission rod 303, and the transmission rod 303 is fixed to the center of one end of the slag cleaning pipe 1, and the center of the other transmission chain 301 is connected to a reduction motor 304, and the reduction motor 304 is fixed to the top of the sedimentation tank. The corresponding sealing cover 2 is provided with a gap for the transmission chain 301 to pass through, and the gap is set at the back side position of blocking floating garbage so that it does not affect the blocking effect. Thus, the slag cleaning pipe 1 can be swung back and forth through the chain transmission and the reduction motor 304. Each time it swings downward, the slag inlet gap is submerged in the sewage level, and the sewage and floating garbage will enter the interior of the slag cleaning pipe 1;

[0028] In order to further discharge and separate sewage and floating garbage, a discharge port 4 is opened at one end of the slag cleaning pipe 1. The discharge port 4 is a curved arc structure with a circular trajectory. A discharge pipe 9 is provided on one side of the discharge port 4 and passes through the slag cleaning pipe 1. A filter box 10 is provided at the discharge end of the discharge pipe 9. A filter mesh plate is provided on the top of the filter box 10. A liquid outlet is provided on one side of the filter box 10. The liquid outlet discharges the filtered sewage to the outside for centralized collection. The centralized collected sewage shell is then input into the sedimentation tank through the pump body. The sewage and floating garbage entering the slag cleaning pipe 1 can enter the inside of the sealing cover 2 through the discharge port 4, and then be transported to the filter box 10 for filtration through the discharge pipe 9.

[0029] In the embodiment of the present invention, in order to push the floating garbage inside the slag cleaning pipe 1, a straight plate 7 is provided inside the slag cleaning pipe 1, and a plurality of paddles 8 are connected to the outer periphery of the straight plate 7. The outer periphery of the paddles 8 is adapted to the inner periphery of the slag cleaning pipe 1, and through adaptation, it plays a role of limiting. A flow gap is provided between the bottom of the paddles 8 and the inner periphery of the slag cleaning pipe 1. When the floating garbage passes through the flow gap, it can be pushed out.

[0030] In order to realize the driving of the straight plate 7, a cam driving structure 5 is provided on one side of the interior of the slag cleaning pipe 1. The cam driving structure 5 includes a cylindrical cam 501 and a disc 502 that adapt to each other. The bottom of the disc 502 is rotatably connected to the bending extension plate 11. A fixing rod 12 is connected to one side of the bending extension plate 11. The end of the fixing rod 12 is fixed to the side wall of the sedimentation tank. As a result, the disc 502 is fixedly arranged inside the slag cleaning pipe 1. A plurality of limiting posts 503 that adapt to the cylindrical cam 501 are installed on one side of the disc 502. A center rod 504 is connected to the center of the cylindrical cam 501. The center rod 504 is fixed to the transmission rod 303. As a result, the cylindrical cam 501 swings along with the slag cleaning pipe 1, so that during the swinging process, the cylindrical cam 501 drives the disc 502 connected to the limiting posts 503 to rotate back and forth.

[0031] A connecting rod structure 6 is provided below the cam drive structure 5. The connecting rod structure 6 includes two latches 601, which are respectively connected to the bottom of the disc 502 and the top of the straight plate 7. A connecting rod 602 is provided between the two latches 601. The two ends of the connecting rod 602 are provided with connecting rod heads with annular structures. When the disc 502 rotates back and forth, the connecting rod 602 is driven to rotate and move, generating a pulling and pushing force, thereby causing the straight plate 7 to reciprocate, further causing the shifting plate 8 to reciprocate and move the floating garbage.

[0032] It should be noted here that the reciprocating movement of the straight plate 7 is as follows: when the slag cleaning pipe 1 rotates toward the sewage, the straight plate 7 moves away from the discharge port 4; when the slag cleaning pipe 1 is reset, the straight plate 7 moves toward the discharge port 4. After the sewage is input, it is delivered, and this reciprocating movement achieves a better delivery effect.

[0033] Working Principle: This embodiment provides a high-efficiency sedimentation tank rotary skimmer pipe slag cleaning device. When in use, the device is placed downstream, with the lower half submerged in the horizontal surface to block floating garbage. The external control structure controls the operation of the reduction motor 304, driving the sprocket 302 to rotate back and forth, causing the transmission rod 303 to rotate, further causing the slag cleaning pipe 1 to swing back and forth within a swing range of about 90 degrees. When the slag inlet notch swings to be submerged in the horizontal plane, the sewage and floating garbage on the upper surface enter the slag cleaning pipe 1, enter the interior of the sealing cover 2 through the discharge port 4, and then be transported to the filter box 10 through the discharge pipe 9 for filtration.

[0034] At the same time, the rotation of the slag cleaning pipe 1 drives the central rod 504 to rotate, so that the cylindrical cam 501 drives the disc 502 connected to the limit column 503 to rotate back and forth. When the disc 502 rotates back and forth, it drives the connecting rod 602 to rotate and move, further generating a moving pulling and pushing force, thereby causing the straight plate 7 to move back and forth, and further causing the shifting plate 8 to shift the floating garbage back and forth.

[0035] The embodiments disclosed in the present invention are preferred embodiments, but are not limited to them. Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. As long as they do not deviate from the spirit of the present invention, they are all within the scope of protection of the present invention.
