Description

Technical Field

[0002] At present, with the improvement of people's living standards, people's environmental awareness is getting stronger and stronger, which makes people pay attention to sewage treatment. Sewage refers to the polluted water discharged from life and production, which contains a large amount of phosphorus, which will lead to eutrophication of water bodies and harm aquatic organisms. Therefore, it is necessary to carry out phosphorus removal and precipitation treatment on sewage. At present, it is common to add phosphorus removal agent to sewage, and then convert the phosphorus-containing substances in sewage into sediment through sufficient stirring and mixing, and then filter and discharge it, so as to achieve the purpose of phosphorus removal from sewage.

[0003] Chinese patent announcement No. CN220835274U discloses a stirring and mixing device for phosphorus removal and precipitation in sewage.

[0014] In summary, the present invention includes the following beneficial technical effects:

[0015] 1. The present invention provides a filter plate, a vertical reciprocating structure, a support plate, a stirring frame and a collecting structure. The intermittent power output structure intermittently outputs power to the vertical reciprocating structure, driving the support plate corresponding to the vertical reciprocating structure to move upward. When the liquid and sediment above the support plate move upward, as the liquid is higher than the top of the partition, the liquid passes through the filter plate from the water trough to the other side of the partition, and the sediment remains above the support plate. When the upper surface of the support plate moves above the upper surface of the supporting outer box, the stirring frame pushes the sediment from the two ends of the support plate to the collecting structures on the front and rear sides when moving forward and backward, so that the generated sediment can be separated in time, and then the liquid separated from the sediment flows to between the two partitions on the other side, effectively preventing the stirring frame from moving for a long time and breaking up the sediment.

[0016] 2. The present invention arranges a vertical telescopic rod, a bending baffle, a movable strut and a pressure telescopic rod. When the support plate is at the bottom, the pressure telescopic rod pushes the gap between the stirring square frame and the support plate, thereby ensuring that during the sedimentation reaction, the stirring square frame reduces the sediment that settles downward when it moves. When the support plate moves upward, the support plate first pushes the stirring square frame to compress the vertical telescopic rod through the movable strut and the pressure telescopic rod. When the upper end of the stirring square frame contacts the bending baffle, the support plate continues to move upward, and the support plate compresses the pressure telescopic rod through the movable strut. When the upper surface of the support plate moves above the upper surface of the supporting outer box, the bottom surface of the support plate is located below the upper surface of the supporting outer box, and the support plate contacts the stirring square frame. When the stirring square frame moves back and forth, it pushes the sediment on the upper surface of the support plate into the two collecting structures.

[0017] 3. The present invention arranges ridge rods, internally threaded rods, conveyor belts, gears and rack belts. The double-axis power box B drives the two conveyor belts to rotate relative to each other. The rack belts installed on the surfaces of the two conveyor belts mesh with the same gear in turn. When the rack belt on the surface of the conveyor belt on one side meshes with the gear, it drives the cover shaft to rotate. Then the internally threaded rod pushes the support plate to move upward by meshing with the ridge rod. When the rack belt is disengaged from the gear, the upper surface of the support plate is located above the upper surface of the supporting outer box, and the bottom surface of the support plate is located below the upper surface of the supporting outer box. Then the rack belt on the surface of the other conveyor belt meshes with the gear after a certain gap, ensuring that the stirring square frame has enough time to move back and forth to push the sediment above the support plate to the inside of the collection structure on both sides.

[0030] A plurality of inclined water-splashing plates 16 are fixedly connected to the lower end of the mixing square frame 5, and the inclination directions of two adjacent inclined water-splashing plates 16 are opposite. When the inclined water-splashing plates 16 move forward and backward with the mixing square frame 5, the mixing efficiency of the liquid is increased when the mixing square frame 5 moves. A vertical telescopic rod 17 is fixed to the bottom surface of the hanging block 10, and the lower end of the vertical telescopic rod 17 is fixed to the mixing square frame 5. A bending retaining frame 18 is arranged above the mixing square frame 5, and both ends of the bending retaining frame 18 are fixed to the outer surface of the supporting outer box 1. The left and right sides of the mixing square frame 5 are slidably connected with movable struts 19, and the lower end of the movable struts 19 is rotatably connected with a roller 20. The upper end of the movable struts 19 is fixed with a pressure telescopic rod 21. The other end of the retractable rod 21 is fixed to the mixing square frame 5, and the elasticity of the pressure telescopic rod 21 is greater than the elasticity of the vertical telescopic rod 17. When the pallet 3 moves upward, the roller 20 pushes the movable support bar 19, the pressure telescopic rod 21 and the mixing square frame 5 to compress the vertical telescopic rod 17. After the upper end of the mixing square frame 5 contacts the bending baffle 18, the pallet 3 continues to move upward, and the pallet 3 compresses the pressure telescopic rod 21 through the movable support bar 19. When the upper surface of the pallet 3 moves above the upper surface of the supporting outer box 1, the bottom surface of the pallet 3 is located below the upper surface of the supporting outer box 1, and the pallet 3 contacts the mixing square frame 5. The mixing square frame 5 pushes the sediment on the upper surface of the pallet 3 away from the pallet 3 when moving back and forth.

[0031] A longitudinal reciprocating structure 4 for controlling the forward and backward movement of the hanging block 10 is arranged above the supporting outer box 1 . The longitudinal reciprocating structure 4 is connected to the supporting outer box 1 , and the hanging block 10 is connected to the longitudinal reciprocating structure 4 .

[0032] The longitudinal reciprocating structure 4 includes a double-axis power box A41 and an engaging strip 42. The two output shafts of the double-axis power box A41 are fixed with reciprocating screws 43. The two ends of the engaging strip 42 are respectively threadedly sleeved on the outer surfaces of the two reciprocating screws 43. The double-axis power box A41 is fixed to the supporting outer box 1. The front end of the reciprocating screw 43 is rotatably connected to the outer surface of the supporting outer box 1. The hanging block 10 is fixed to the engaging strip 42. When the double-axis power box A41 drives the two reciprocating screws 43 to rotate, the engaging strip 42 drives the hanging block 10 to reciprocate back and forth by engaging with the reciprocating screw 43.

[0033] A filter plate 11 is fixed to the upper end of each partition 2, and a matching water-passing plate 12 is fixed to the right side of the filter plate 11.

The upper end of the one-way water baffle 23 is elastically rotatably connected to the inner wall of the water trough 9, and the one-way water baffle 23 has a tendency to contact with the baffle 22. When water flows into the side of the baffle 22 away from the one-way water baffle 23, the water flow can push the one-way water baffle 23 to rotate, so that water can flow to the other side of the water-passing plate 12, and when water flows in from the other side of the water trough 9, the water flow cannot flow to the other side of the water-passing plate 12 due to the obstruction of the one-way water baffle 23, so that the water flow can only flow in one direction to the right.

[0037] An intermittent power output structure 8 for intermittently outputting power to the vertical reciprocating structure 7 is installed on the bottom surface of the supporting outer box 1. The intermittent power output structure 8 is connected to one end of the vertical reciprocating structure 7 located below the supporting outer box 1. The intermittent power output structure 8 includes a double-axis power box B81 and two conveyor belts 82. The two conveyor belts 82 rotate in opposite directions. The gear 74 is located between the two conveyor belts 82. Both ends of the interior of each conveyor belt 82 are in rolling contact with a transmission roller 83. The upper end of the transmission roller 83 is rotatably inserted into the bottom surface of the supporting outer box 1.

When the liquid and sediment above the support plate 3 move upward, as the liquid is higher than the top of the partition 2, the liquid passes through the filter plate 11 from the water trough 9 to the other side of the partition 2, and the sediment remains above the support plate 3. When the upper surface of the support plate 3 moves above the upper surface of the supporting outer box 1, the stirring frame 5 pushes the sediment from the two ends of the support plate 3 to the aggregation box 61 on the front and rear sides when moving forward and backward, so that the generated sediment can be separated in time, and then the liquid separated from the sediment flows to between the two partitions 2 on the other side for re-sedimentation treatment.
