[0024] As shown in Figure 3 , 5 -6, the second transmission wheel 8 is connected with the gas stirring device in the following manner: the second transmission wheel 8 is provided with periodically arranged transmission grooves 801, the transmission grooves 801 are provided with sliding blocks 802 capable of sliding along the transmission grooves 801, one end of the transmission grooves 801 is hingedly connected with a transmission rod 803, the other end of the transmission rod 803 is fixed with a piston 805, the piston 805 is capable of sliding in a cylinder 10, the transmission rod 803 is provided with a first limiter 804 capable of controlling the axial movement of the transmission rod 803, and the first limiter 804 is fixed on the cylinder 10.

[0025] The cylinder 10 is provided with an air inlet one-way valve, specifically, the air inlet is a horn-shaped port with a large upper part and a small lower part, and the horn-shaped port is provided with a check ball 806 serving as the air inlet one-way valve. The check ball 806 can control the air inlet to be capable of air intake but not air exhaust.

[0026] The cylinder 100 is connected with one end of a gas stirring pipe 11, the gas stirring pipe 11 is provided with an air exhaust one-way valve 13, and the other end of the gas stirring pipe 11 is annularly and horizontally provided with a gas stirring branch pipe 111, the gas stirring branch pipe 111 is provided with a plurality of vertically arranged gas stirring nozzles 112, and the radial direction of the gas stirring nozzles 112 is provided with a plurality of nozzles 114.

[0027] As shown in Figure 5 , the distribution density of the nozzles 114 in the lower part of the gas stirring nozzles 112 is greater than that in the upper part, so that the nozzles 114 are distributed sparsely in the upper part and densely in the lower part, and the gas stirring is more uniform.

[0028] As shown in Figure 6 , in order to make the air intake of the cylinder 10 more stable and prevent the check ball 806 from being blown out, when the cylinder 10 is air-intaking to the limit, the point on the transmission groove 801 where the sliding block 802 is located and the adjacent area thereof are the first transmission groove area 8011; when the cylinder 10 is air-exhausting to the limit, the point on the transmission groove 801 where the sliding block 802 is located and the adjacent area thereof are the second transmission groove area 8012; and the curvature radius of the second transmission groove area 8012 is smaller than that of the first transmission groove area 8011.

[0029] As shown in Figure 4 , Figures 7-8Multiple first guide rods (acting as levers) 701 are fixed on the side of the first transmission wheel 7. A second guide rod (acting as a lever) 702 is provided on the side of the first transmission wheel 7. The second guide rod 702 is hinged to the treatment pool 1 through a first pin (acting as a fulcrum). When the first transmission wheel 7 rotates, one end of the second guide rod 702 can reach the contour swept by the first guide rod 701. The other end of the second guide rod 702 contacts one end of a return spring (such as a compression spring) 707. The other end of the return spring 707 contacts a fixing block 706. The fixing block 706 is fixed to the treatment pool 1. One end of the second guide rod 702 is hinged to a third guide rod 703. The other end of the third guide rod 703 can abut against the hose 162. A second limiter 708 is provided on the outside of the third guide rod 703 to "control its axial movement". The second limiter 708 is fixed to the treatment pool 1.

[0030] The flexible tube 162 is a section of the dosing tube 161. One end of the dosing tube 161 is connected to the liquid tank 16, and the other end of the dosing tube 161 is the dosing port.

[0031] like Figures 1-2 The first transmission wheel 7 is connected to the third transmission wheel 9, which is rotatably connected to the treatment tank 1, and multiple stirring blades 12 are fixed on it; the side of the stirring blades 12 is fixed with guide protrusions 121.

[0032] The stirring blades 12 are arranged alternately on the second drive shaft 6.

[0033] like Figures 1-2 The treatment tank 1 is provided with a first baffle 101, a second baffle 102, and a third baffle 103 in sequence from upstream to downstream. The first baffle 101 is located between the first drive shaft 5 and the second drive shaft 6. The bottom of the first baffle 101 and the bottom plate of the treatment tank 1 form a water flow channel. The gas stirring branch pipe 111 is located in the upstream area of ​​the first baffle 101. The downstream area of ​​the third baffle 103 is provided with multiple parallel inclined plates 104. Multiple mud hoppers 105 are provided below the inclined plates 104. The mud hoppers 105 are provided with mud discharge pipes 13. The mud discharge pipes 13 are provided with electric mud discharge valves 14.

[0034] The treatment tank 1 is equipped with an outlet pipe 15, which is located in the downstream area of ​​the inclined plate 104. The inlet of the outlet pipe 15 is connected to the outlet trough 16, which is fixed on the inner wall of the treatment tank 1.

[0035] The treatment tank 1 is equipped with a mud level gauge 17.

[0036] Its working principle is as follows: S1. Raw water enters the water distribution chamber 3 through the water inlet pipe 2. The water distribution chamber 3 buffers and distributes the water flow evenly. The raw water flows out through the water distribution port 301 and the water flow is evenly sprayed onto the transmission blade 4, which drives the first transmission shaft to rotate 5, the first transmission wheel 7 and the second transmission wheel 8 to rotate.

[0037] S2. When the second transmission wheel 8 rotates, it drives the slider 802 to move relative to the transmission groove 801. Under the action of the limiter 804, the slider 802 drives the transmission rod 803 to reciprocate, and the transmission rod 803 pushes the piston 805 to reciprocate.

[0038] When piston 805 moves upward, cylinder 10 performs an intake action, specifically: exhaust check valve 113 closes, the air pressure inside cylinder 10 decreases, outside gas blows up check ball 806 and the air inlet opens, allowing outside air to enter cylinder 10. When piston 805 moves downward, cylinder 10 performs an intake action. Specifically, check ball 806 is locked in the air inlet, closing the intake one-way valve. The air pressure inside cylinder 10 increases, the exhaust one-way valve 113 is opened, and the gas in cylinder 10 is blown up along check ball 806. The air inlet is opened, and the gas inside cylinder 10 enters the treatment tank 1 along gas stirring pipe 11, gas stirring branch pipe 111, gas stirring nozzle 112, and nozzle 114 for air stirring.

[0039] S3. The first drive wheel 7 drives the third drive wheel 9. The third drive wheel 9 is connected to the second drive shaft 6 and the stirring blade 12. After being driven by the first drive wheel 7, it carries out the flocculation reaction. The blade is provided with a guide protrusion 121 to make the water flow turbulent, so as to ensure that the flocculant and impurities in the water are in full contact to form flocs.

[0040] S4. When the first transmission wheel 7 rotates, the first guide rod 701 intermittently pushes the second guide rod 702 and the third guide rod 703 to rotate to the high position. When the first guide rod 701 does not contact the second guide rod 702, it is reset to the low position by relying on the return spring 707 and the third guide rod 703.

[0041] When the third guide rod 703 is in the low position, the third guide rod 703 does not contact the hose 162, the dosing tube 161 is open, and the dosing tank 16 can be dosing; When the third guide rod 703 is in the high position, the third guide rod 703 contacts the hose 162 and closes it, the dosing tube 161 is not connected, and the dosing tank 16 cannot be filled with medicine; This allows for periodic application of the medication.

[0042] Features of this application: S1. The first drive wheel 7 and the first guide rod 701 are connected by a threaded connection. The number of first guide rods 701 can be increased or decreased according to the water quality to control the amount of flocculant added.

[0043] S2. The gas stirring head 112 is provided with radial openings, which are sparse at the top and dense at the bottom, so that the gas is stirred more evenly.

[0044] S3. By reading the mud level gauge parameters through the PLC manager, the remote electric mud discharge valve 14 can be automatically controlled to discharge mud, making the system more flexible, efficient, stable and reliable, while reducing labor costs and improving the system's processing effect.

[0045] S4. The present invention is equipped with a hydraulic drive mechanism to drive the gas stirring operation without consuming electricity, thus saving resources.

[0046] S5. This invention provides a non-powered self-coagulation sedimentation device, relating to the field of water treatment technology. The non-powered self-coagulation sedimentation device includes a treatment tank, a transmission device, a stirring device, a solution tank, etc.; a water distribution bag is provided at the water inlet to buffer and evenly distribute the water flow. The water flows out through the distribution port and evenly hits the transmission blades, driving the first transmission shaft to rotate, thus fully utilizing the hydraulic kinetic and potential energy; through a clever structural design, the hydraulic kinetic and potential energy of the incoming water is used to drive the piston to reciprocate, compressing air in the cylinder. The compressed air enters the treatment tank through a gas stirring pipe for air stirring; the radial opening design of the gas stirring head makes gas stirring more uniform; the solution tank dosing pipe... The system features a flexible hose that contacts the end of a third guide rod. As the first drive wheel rotates, the third guide rod moves periodically, enabling automatic periodic dosing of the flocculant. The amount of flocculant added can be controlled by adjusting the number of first guide rods. The stirring blades are staggered on the second drive shaft, with guide protrusions on the blades to create turbulence in the water flow, ensuring sufficient contact between the flocculant and impurities in the water to form flocs and promote flocculation and sedimentation. The PLC manager reads the sludge level gauge parameters, enabling remote automatic control of the electric sludge discharge valve, making the system more flexible, efficient, stable, and reliable, while also reducing costs and improving system treatment efficiency.
