[0037] A dosing device 9, which is used to add flocculants to the sewage in the treatment tube 7;

[0038] The bottom of the slag removal cylinder 1 is fixedly connected to the top of the processing cylinder 7 through a bracket, the bottom of the discharge pipe 4 is connected to the top of the processing cylinder 7, multiple groups of discharge pipes 4 are provided, and the multiple groups of discharge pipes 4 are evenly distributed on one side of the slag removal cylinder 1, one side of the slag cleaning device 8 is fixedly connected to the outside of the slag removal cylinder 1, and one side of the dosing device 9 is fixedly connected to the outside of the processing cylinder 7.

[0039] The slag cleaning device 8 includes a driving motor 81, the output end of the driving motor 81 is fixedly connected to a rotating column 82, the outer side of the rotating column 82 is located at the center position and is fixedly connected to a positioning sleeve 83, the outer side of the positioning sleeve 83 is fixedly connected to a moving plate 84, the side of the moving plate 84 away from the positioning sleeve 83 is fixedly connected to an extrusion plate 85, the outer side of the rotating column 82 is located at both ends and is sleeved with a rotating sleeve 86, the outer side of the rotating sleeve 86 is fixedly connected to a limiting plate 87, and an extrusion port 88 is opened on one side of the limiting plate 87.

[0040] The outer side of the driving motor 81 is fixedly connected to the outer side of the slag removing barrel 1, the output end of the driving motor 81 passes through one end of the slag removing barrel 1 and is rotatably connected to the end of the slag removing barrel 1 through a sealed bearing, the end of the rotating column 82 away from the driving motor 81 passes through one end of the slag removing barrel 1 and is rotatably connected to the end of the slag removing barrel 1 through a bearing, and the inner wall of the rotating sleeve 86 is rotatably connected to the outer side of the rotating column 82 through a bearing.

[0041] There are multiple groups of extrusion ports 88, which are evenly distributed on the rotating sleeve 86. There are multiple groups of extrusion plates 85, which correspond to the extrusion ports 88 one by one. The side of the limiting plate 87 away from the rotating sleeve 86 is fixedly connected to the inner wall of the slag removal cylinder 1.

[0042] During use, the worker pours the sewage to be treated into the slag removal barrel 1 from the feed pipe 2, and then turns on the driving motor 81. The driving motor 81 drives the rotating column 82 to rotate, and the rotating column 82 drives the positioning sleeve 83 to rotate, and the positioning sleeve 83 drives the moving plate 84 to move, and the moving plate 84 drives the squeezing plate 85 to rotate. When the squeezing plate 85 rotates, the solid matter in the sewage in the slag removal barrel 1 is pushed.

Then, the control valve 3 is opened to discharge the sewage in the slag removal barrel 1 into the treatment barrel 7 through the discharge pipe 4. After the sewage is discharged, the worker manually opens the sealing door panel 6, and the solid matter clamped between the squeezing plate 85 and the limit plate 87 can be taken out through the slag discharge port 5, so that the solid residue with a larger volume inside the sewage can be cleaned, which is convenient for the subsequent flocculation operation of the sewage.

[0043] For the second embodiment, please refer to Figure 1-Figure 8The present invention provides a technical solution: on the basis of the first embodiment, the dosing device 9 includes a rotating motor 91, the output end of the rotating motor 91 is fixedly connected to a rotating shaft 92, the end of the rotating shaft 92 away from the rotating motor 91 is fixedly connected to a liquid storage shell 93, the bottom of the liquid storage shell 93 is connected to an addition pipe 94, the bottom of the addition pipe 94 is connected to a liquid inlet pipe 95 through a sealing bearing, the bottom of the liquid inlet pipe 95 is connected to a liquid pump 96, the outer side of the liquid storage shell 93 is connected to an extension pipe 97, the end of the extension pipe 97 away from the liquid storage shell 93 is fixedly connected to a fixed sleeve 98, the outer side of the fixed sleeve 98 is evenly opened with an arc-shaped opening 910, the inner wall of the extension pipe 97 is slidably connected to a conical plug 911, one side of the conical plug 911 is fixedly connected to a return spring 912, the outer side of the liquid storage shell 93 is installed with a mixing device 99, and the inner wall of the processing cylinder 7 is evenly installed with a reinforcing plate 913.

[0044] The outer side of the rotating motor 91 is fixedly connected to the top of the processing cylinder 7, the output end of the rotating motor 91 passes through the top of the processing cylinder 7 and is rotatably connected to the processing cylinder 7 through a sealed bearing, and the adding tube 94 passes through the bottom of the processing cylinder 7 and is rotatably connected to the processing cylinder 7 through a bearing.

[0045] The bottom of the liquid pump 96 is fixedly connected to the top of the base 11 through a bracket, multiple groups of extension tubes 97 are provided, and the multiple groups of extension tubes 97 are evenly distributed on the outside of the liquid storage shell 93, and multiple groups of mixing devices 99 are provided and correspond one by one to the extension tubes 97. The end of the return spring 912 away from the conical plug 911 is fixedly connected to the inner wall of the fixed sleeve 98.

[0046] The mixing device 99 includes a rolling column 991, both ends of which are rotatably connected to support rods 992 through bearings, the outer side of the rolling column 991 is centrally sleeved and fixedly connected to a limiting sleeve 993, the outer side of the limiting sleeve 993 is fixedly connected to a flip plate 994, and the outer side of the rolling column 991 near both ends is fixedly connected to mixing plates 995.

[0047] One end of the support rod 992 away from the rolling column 991 is fixedly connected to the outer wall of the liquid storage shell 93, multiple groups of flip plates 994 are provided, and the multiple groups of flip plates 994 are evenly distributed on the outside of the limiting sleeve 993, and multiple groups of mixing plates 995 are provided.

[0048] During use, when sewage enters the treatment barrel 7 from the discharge pipe 4, the liquid pump 96 is turned on to pump the external flocculant into the liquid inlet pipe 95, and the flocculant enters the liquid storage shell 93 through the liquid inlet pipe 95. The rotating motor 91 is turned on to drive the liquid storage shell 93 to rotate. The liquid storage shell 93 drives the extension tube 97 to rotate when rotating. The flocculant filled in the liquid storage shell 93 and the extension tube 97 is pushed by the centrifugal force to push the conical plug 911, and the conical plug 911 is continuously pushed out from the extension tube 97. When the extension tube 97 moves, the reset spring 912 is squeezed. As the conical plug 911 continuously slides out from one end of the extension tube 97, the flocculant inside the extension tube 97 is thrown from one end of the extension tube 97 into the treatment barrel 7, and the flocculant can be added to facilitate the flocculation and precipitation of floating objects and fine particles in the sewage.

[0049] By adjusting the rotation speed of the rotating motor 91, the centrifugal force on the flocculant in the liquid storage shell 93 and the extension tube 97 is changed. When the rotating motor 91 rotates at a faster speed, the centrifugal force on the flocculant is larger, and the flocculant pushes the conical plug 911 to move a longer distance, thereby increasing the amount of flocculant delivered from the extension tube 97 to the treatment tube 7. When the rotating motor 91 rotates at a slower speed, the flocculant pushes the conical plug 911 to move a shorter distance, thereby reducing the amount of flocculant delivered to the treatment tube 7. The dosage of flocculant can be adjusted in time according to actual needs to avoid wasting flocculant.

[0050] When the liquid storage shell 93 rotates, it drives the support rod 992 to move, and the support rod 992 drives the rolling column 991 to move. When the rolling column 991 moves to the position of the reinforcement plate 913, the reinforcement plate 913 squeezes and pushes the passing flip plate 994. When the flip plate 994 moves, it drives the rolling column 991 to rotate around its axis. The rolling column 991 drives the mixing plate 995 to rotate. The mixing plate 995 can mix the added flocculant and sewage, improve the mixing efficiency of the agent and sewage, and accelerate the flocculation speed.

[0051] Working principle: The worker pours the sewage to be treated into the slag removal barrel 1 from the feed pipe 2, and then turns on the drive motor 81, which drives the rotating column 82 to rotate, and the rotating column 82 drives the positioning sleeve 83 to rotate, and the positioning sleeve 83 drives the moving plate 84 to move, and the moving plate 84 drives the extrusion plate 85 to rotate. When the extrusion plate 85 rotates, it pushes the solids in the sewage in the slag removal barrel 1. As the extrusion plate 85 continues to move, the extrusion plate 85 pushes the solids to approach the limit plate 87 continuously until one end of the extrusion plate 85 is inserted into the extrusion port 88, so that the solids can be clamped between the extrusion plate 85 and the limit plate 87, and then the control valve 3 is opened to discharge the solids in the slag removal barrel 1 through the discharge pipe 4. The sewage is discharged into the treatment barrel 7. After the sewage is discharged, the worker manually opens the sealing door panel 6, and the solid matter sandwiched between the extrusion plate 85 and the limit plate 87 can be taken out through the slag discharge port 5. The solid residue with a larger volume inside the sewage can be cleaned, which is convenient for the subsequent flocculation operation of the sewage. When the sewage enters the treatment barrel 7 from the discharge pipe 4, the liquid pump 96 is turned on to pump the external flocculant into the liquid inlet pipe 95, and the flocculant enters the liquid storage shell 93 through the liquid inlet pipe 95. The rotating motor 91 is turned on to drive the liquid storage shell 93 to rotate. When the liquid storage shell 93 rotates, it drives the extension tube 97 to rotate. The flocculant filled in the liquid storage shell 93 and the extension tube 97 is driven by the centrifugal force to push the cone. The plug 911 continuously pushes the conical plug 911 out of the extension tube 97. When the extension tube 97 moves, the return spring 912 is squeezed. As the conical plug 911 continuously slides out from one end of the extension tube 97, the flocculant inside the extension tube 97 is thrown from one end of the extension tube 97 into the treatment tube 7. The flocculant can be added. The rotation speed of the rotating motor 91 is adjusted, and the centrifugal force on the flocculant in the liquid storage shell 93 and the extension tube 97 is changed. When the rotation speed of the rotating motor 91 is faster, the centrifugal force on the flocculant is larger, and the flocculant pushes the conical plug 911 to move a longer distance, so that the amount of flocculant added from the extension tube 97 to the treatment tube 7 increases. 1 The rotation speed is slow, the distance that the flocculant pushes the conical plug 911 to move is short, and the dosage of the flocculant added to the treatment tube 7 is reduced. The dosage of the flocculant can be adjusted in time according to actual needs. When the liquid storage shell 93 rotates, it drives the support rod 992 to move, and the support rod 992 drives the rolling column 991 to move. When the rolling column 991 moves to the position of the reinforcing plate 913, the reinforcing plate 913 squeezes and pushes the passing flip plate 994. When the flip plate 994 moves, it drives the rolling column 991 to rotate around its axis. The rolling column 991 drives the mixing plate 995 to rotate, and the mixing plate 995 can mix the added flocculant and sewage to improve the mixing efficiency of the agent and sewage.
