Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, in particular to sewage treatment equipment for municipal environmental protection projects. Background Art

[0002] Sewage treatment refers to the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people. In the process of sewage treatment, sewage treatment equipment is often needed;

[0003] Most of the stirring directions adopted by existing devices when mixing sewage treatment agents and sewage are towards the same place. Eddy currents are easily generated during the stirring and mixing process, which makes it impossible for the sewage treatment agent and sewage to be fully mixed, thereby reducing the mixing effect. For this reason, we provide a sewage treatment equipment for municipal environmental protection projects. Utility Model Content

When the bevel gear three 109 rotates, the outer ring plate 110 is driven to rotate, and the internal stirring rod 111 is driven to rotate by the rotation of the outer ring plate 110. Because the rotation direction of the bevel gear three 109 is opposite to that of the bevel gear one 106, the rotation direction of the external stirring rod 105 is opposite to that of the internal stirring rod 111, so that the sewage and the flocculant can be fully mixed when the device is mixing, thereby improving the working efficiency.

[0028] The right side of the bevel gear 2 108 is rotationally connected to the left side of the connecting frame 107 , the left side of the connecting frame 107 is rotationally connected to the right side of the bevel gear 2 108 , and the inner wall of the bevel gear 3 109 is rotationally connected to the outer surface of the rotating shaft 103 .

The inner wall of the slide groove 209 is slidably connected to a slide rod 212. A movable plate 213 is fixedly connected to the left side of the slide rod 212. A spring 214 is fixedly connected to the top of the movable plate 213. The top of the spring 214 is fixedly connected to the inner wall of the filter tank 220.

[0033] The bottom of the movable plate 213 is fixedly connected to a fixed rod 218, and the bottom of the fixed rod 218 is rotatably connected to a slider 217. The outer surface of the slider 217 is slidably connected to the filter plate 210. A slide groove 216 is provided inside the filter plate 210. The inner wall of the slide groove 216 is slidably connected to the outer surface of the slider 217. The filter plate 210 is rotatably connected to a central axis 211. The left and right sides of the central axis 211 are respectively fixedly connected to the left and right sides of the inner wall of the filter tank 220. When the reset rod 208 rotates, the slider 212 will slide along the slide groove 209, and at the same time drive the movable plate 213 to move. The movable plate 213 moves up and down and squeezes the spring 214. When the movable plate 213 moves up and down, it drives the fixed rod 218 to rotate. When the fixed rod 218 moves, the filter plate 210 is pulled to rotate through the slider 217, so that the filter plate 210 is tilted. The tilt drives the debris on the top of the filter plate 210 to move and fall onto the guide plate 205, and then enters the sewage layer 202 through the guide plate 205 and is discharged through the sewage outlet 203, so as to prevent the debris on the top of the filter plate 210 from filtering and affecting the filtering effect.

[0034] The front and back sides of the treatment box 116 are fixedly connected with sewage layers 202, and the right side of the treatment box 116 is fixedly connected with a water outlet pipe 201.

A guide plate 205 is fixedly connected to the side of the sewage layer 202 close to the treatment box 116.

[0035] A specific application of this embodiment is: the staff first puts the flocculant into the storage box 101, and then puts the sewage into the treatment box 116, and opens the solenoid valve 115 to allow the flocculant in the storage box 101 to flow into the treatment box 116 and mix with the sewage, and at the same time starts the motor 102, the motor 102 starts to drive the shaft 103 to rotate, and the shaft 103 rotates to drive the connecting plate 104 to rotate, and then the connecting plate 104 rotates to drive the external stirring rod 105 to rotate, and during the rotation of the shaft 103, the bevel gear 106 is driven to rotate, and the bevel gear 106 is driven to rotate. The rotation of bevel gear 106 drives bevel gear 2 108 to rotate and drives bevel gear 3 109 to rotate, so that the rotation direction of bevel gear 3 109 is opposite to that of bevel gear 106. When bevel gear 3 109 rotates, it drives outer ring plate 110 to rotate, and the rotation of outer ring plate 110 drives the internal stirring rod 111 to rotate. Because the rotation direction of bevel gear 3 109 is opposite to that of bevel gear 1 106, the rotation direction of external stirring rod 105 is opposite to that of internal stirring rod 111, so as to prevent vortex from being generated when sewage and flocculant are mixed because the stirring directions are the same, so that the mixing effect is improved. The effect is reduced, resulting in reduced work efficiency. After the mixing is completed, the water pump 113 is started. The water pump 113 is started to pump the mixed sewage into the filter tank 220 through the delivery pipe 112. When the sewage enters the filter tank 220, it drives the impeller 206 to rotate, and the sewage falls on the filter plate 210, through which the particles formed by the flocculant are filtered. When the impeller 206 rotates, it drives the connecting shaft 1 207 to rotate. When the connecting shaft 1 207 rotates, the connecting shaft 2 219 is driven to rotate through the belt 215. The reset rod 208 is driven to rotate through the rotation of the connecting shaft 219. When the reset rod 208 rotates, the sliding rod 212 will slide along the sliding groove 209, and at the same time drive the movable plate 213 to move up and down and squeeze the spring 214. When the movable plate 213 moves up and down, it will drive the fixed rod 218 to rotate. When the fixed rod 218 moves, the filter plate 210 will be pulled to rotate through the sliding block 217, so that the filter plate 210 will tilt. The tilt of the filter plate 210 drives the debris on the top of the filter plate 210 to move and fall onto the guide plate 205, and then enter the sewage layer 202 through the guide plate 205 and be discharged through the sewage outlet 203.
