It easily absorbs moisture and carbon dioxide in the air. It forms corresponding salts with acids, solidifies at low temperatures, and is strongly alkaline. It is miscible with water, alcohol and ether, and is corrosive. Polyethylene polyamine is characterized by having amine, polyoxyethylene, organic silicon oxygen, multi-arm and other structures in the molecular chain, combining their excellent properties, and having good surface activity and temperature resistance.

The pump body is used as a power to suck out the precipitated wastewater in the sedimentation tank through the suction of the pump body, and under the transportation of the pipeline, the wastewater enters the treatment tank, and a treatment agent is added into the treatment tank, so that the wastewater reacts with the treatment agent, and then the wastewater can be treated again, and the wastewater is subjected to multi-stage treatment;

[0008] A slag removal mechanism, which is used to process suspended debris in the wastewater, and is installed on the outer cylindrical surface of the treatment tank and close to the bottom;

[0009] Wherein, the slag removal mechanism comprises a slag storage box, which is installed on the outer cylindrical surface of the processing tank and close to the bottom.

The liquid inlet of the liquid inlet square pipe and the liquid outlet of the liquid outlet square pipe are both equipped with a guide hopper. A filter assembly is installed in the middle of the slag storage box. When the cylinder drives the turning plate to rotate, the wastewater in the processing tank rotates, and the suspended matter carried in the wastewater is moved along the position of the inner wall of the processing tank under the action of centrifugal force.

When the cylinder rotates, it can drive the stirring assembly to rotate as a whole, which can facilitate the contact of the end of the force-bearing rod with the eccentric block when the force-bearing rod rotates. As the force-bearing rod continues to rotate, the force-bearing rod can be pushed outward by the continuous rotation of the force-bearing rod. By utilizing the hinge between the connecting rod and the U-shaped rod, the connecting rod drives the curved blade to rotate and adjust the angle, and the torque spring is elastically deformed by the torque force.

[0020] Preferably, the sealing cone is installed directly below the conical bucket, and the material of the sealing extension edge is rubber.

[0021] The present invention provides a polyethylene polyamine wastewater treatment and recovery device, which has the following beneficial effects:

[0022] 1. The polyethylene polyamine wastewater treatment and recovery device is used for static sedimentation of wastewater in a sedimentation tank, so that large particles of debris in the wastewater are precipitated and fall, and then the wastewater is initially treated. The precipitated wastewater in the sedimentation tank is sucked out by the suction of the pump body, and then the wastewater is transported by a pipeline to a treatment tank, and a treatment agent is added into the treatment tank so that the wastewater reacts with the treatment agent, and then the wastewater can be treated again, and the wastewater is subjected to multi-stage treatment.

[0024] 3. The polyethylene polyamine wastewater treatment and recovery device utilizes the support of a supporting cylinder, and the spherical surface of a sphere fits in the middle of the top of the inner cavity of the cylinder. When the cylinder rotates, it is supported by the rotation of the sphere, so that the cylinder rotates smoothly and is not prone to shaking.

[0025] Fourth, the polyethylene polyamine wastewater treatment and recovery device, as the force-bearing rod is pushed outward by the eccentric block, the connecting rod and the U-shaped rod are hinged so that the connecting rod drives the arc-surface blade to rotate and adjust the angle, and the force-bearing rod is separated from the eccentric block so that the pushing force on the force-bearing rod disappears, and under the torque elastic force of the torque spring, the arc-surface blade rotates in the opposite direction to reset, so that the wastewater can be stirred by the reciprocating rotation of the arc-surface blade.

[0026] 5. The polyethylene polyamine wastewater treatment and recovery device, when the cylinder drives the turning plate to rotate, causes the wastewater in the treatment tank to rotate, and causes the suspended matter carried in the wastewater to move along the inner wall of the treatment tank under the action of centrifugal force, and under the impact of the wastewater fluid, the suspended matter enters the liquid inlet square pipe from the guide hopper, and smoothly enters the slag storage box, and is filtered under the filtration of the filter residue net, and the wastewater enters the treatment tank again under the guidance of the liquid outlet square pipe, and the cycle continues in this way to remove the suspended matter in the wastewater.

[0027] 6. The polyethylene polyamine wastewater treatment and recovery device, when the wastewater enters the slag storage box from the liquid inlet square pipe, under the impact of the wastewater fluid and using the rotation support of the connected round roller, the paddle drives the brush to rotate together, and under the flow of wastewater, the suspended matter filtered by the filter residue net is not easy to flow back.

[0028] 7. The polyethylene polyamine wastewater treatment and recovery device utilizes the contact between the cambered blade and the edge of the guide hopper, so that the cambered blade is subjected to pressing force, and under the support of the connecting rod, the cambered blade drives the elliptical elastic ring to rotate toward the position close to the cylinder, and the elliptical elastic ring is compressed, and the cambered blade is separated from the edge of the guide hopper, and the elastic force of the elliptical elastic ring is utilized to make the cambered blade rotate in the opposite direction for reset, so that the cambered blade swings back and forth, and utilizes the fishtail swinging method to increase the stirring direction of the wastewater.

[0029] 8. The polyethylene polyamine wastewater treatment and recovery device utilizes a sealing cone to contact the wastewater liquid surface. As the wastewater liquid surface in the treatment tank continues to rise, and the sliding rod and the bracket slide together, the sealing cone moves upward under the action of buoyancy, so that the sealing cone drives the sealing extension edge to be embedded in the interior of the conical bucket, so that the liquid outlet at the bottom of the pipeline can be blocked, and the injection of wastewater can be stopped, so that an appropriate amount of wastewater is stored in the treatment tank, and the buoyancy can be used to control the amount of wastewater injected.

[0056] The filter residue net 751 is arc-shaped, the paddles 753 are arc-shaped, and the paddles 753 are evenly distributed in the middle of the outer circumferential surface of the connecting roller 752 .

[0057] The third embodiment, as Figure 1-Figure 5 and Fig. 9 As shown, based on the first embodiment:

[0058] The liquid outlet of the pipe 4 is provided with a floating assembly 8, which is installed inside the treatment tank 2. The floating assembly 8 includes a conical bucket 81 and a bracket 82. The top of the conical bucket 81 is fixedly installed at the liquid outlet at the bottom of the pipe 4. The bracket 82 is fixedly installed inside the pipe 4 and close to the liquid outlet. A sliding rod 83 is slidably installed at the center of the bracket 82. A sealing cone 84 is fixedly installed at the bottom end of the sliding rod 83. A sealing extension edge 85 is fixedly installed on the conical surface outside the sealing cone 84. When the waste When water is continuously injected into the treatment tank 2 from the liquid outlet of the pipe 4, the sealing cone 84 is used to contact the wastewater liquid surface. As the wastewater liquid surface in the treatment tank 2 continues to rise, and the sliding rod 83 and the bracket 82 slide together, the sealing cone 84 moves upward under the action of buoyancy, so that the sealing cone 84 drives the sealing extension edge 85 to be embedded in the interior of the conical bucket 81, so that the liquid outlet at the bottom of the pipe 4 can be blocked, and the injection of wastewater can be stopped, so that an appropriate amount of wastewater can be stored in the treatment tank 2.

[0059] The sealing cone 84 is installed directly below the conical bucket 81 to facilitate the sealing cone 84 to move upwards after being subjected to buoyancy and to promote the matching between the sealing cone 84 and the conical bucket 81. The sealing extension edge 85 is made of rubber.

[0060] When in use, firstly, the wastewater to be treated is injected into the sedimentation tank 1, and the wastewater is allowed to settle in the sedimentation tank 1, so that large particles of debris in the wastewater are precipitated and fall, and then the wastewater is initially treated;

[0061] When the wastewater is precipitated, the pump body 3 is used as a power to suck out the precipitated wastewater in the sedimentation tank 1 through the suction force of the pump body 3, and the wastewater enters the treatment tank 2 under the transportation of the pipeline 4, and the treatment agent is added into the treatment tank 2 so that the wastewater reacts with the treatment agent;

[0062] When wastewater is continuously injected into the treatment tank 2 from the liquid outlet of the pipe 4, the plugging cone 84 is in contact with the liquid surface of the wastewater. As the liquid surface of the wastewater in the treatment tank 2 continues to rise, and the sliding rod 83 and the bracket 82 are slidably matched, the plugging cone 84 is moved upward by the buoyancy, so that the plugging cone 84 drives the sealing extension edge 85 to be embedded in the conical bucket 81, so that the liquid outlet at the bottom of the pipe 4 can be blocked, and the injection of wastewater is stopped, so that an appropriate amount of wastewater is stored in the treatment tank 2.

[0063] At the same time, the staff starts the servo motor 61 to work, and the output end of the servo motor 61 rotates, which can drive the rotating shaft 63 to rotate, so that the cylinder 64 is driven to rotate together, and the turning plate 65 rotates together with the cylinder 64, so that the turning plate 65 rotating in a circle turns the wastewater in the treatment tank 2, so that the wastewater at the bottom of the inner cavity of the treatment tank 2 rolls upward, thereby promoting full contact between the wastewater and the treatment agent;

[0064] And by utilizing the support of the support cylinder 621 and combining the spherical surface of the ball 622 with the middle of the top of the inner cavity of the cylinder 64, the cylinder 64 will be supported by the rotation of the ball 622 when rotating, so that the cylinder 64 rotates smoothly and is not prone to shaking;

[0065] When the cylinder 64 rotates, the stirring assembly 66 can be driven to rotate as a whole, which is beneficial for the end of the force-bearing rod 666 to contact the eccentric block 623 when the force-bearing rod 666 rotates. As the force-bearing rod 666 continues to rotate, the force-bearing rod 666 is pushed outward. By using the hinge between the connecting rod 662 and the U-shaped rod 661, the connecting rod 662 drives the arc blade 664 to rotate and adjust the angle, and the torque spring 663 is elastically deformed by the torque force.

[0066] The force-bearing rod 666 is separated from the eccentric block 623, so that the driving force on the force-bearing rod 666 disappears, and under the torque elastic force of the torque spring 663, the arc blade 664 rotates in the opposite direction to reset, so that the wastewater can be stirred by the reciprocating rotation of the arc blade 664;

[0067] When the cylinder 64 drives the turning plate 65 to rotate, the wastewater in the treatment tank 2 rotates, and the suspended matter carried in the wastewater moves along the inner wall of the treatment tank 2 under the action of centrifugal force, and under the impact of the wastewater fluid, the suspended matter enters the liquid inlet square pipe 72 from the guide hopper 74, and smoothly enters the slag storage box 71, and is filtered by the filter residue net 751, and the wastewater enters the treatment tank 2 again under the guidance of the liquid outlet square pipe 73, and the cycle continues in this way to remove the suspended matter in the wastewater;

[0068] When the arc blade 664 rotates in a circle, the arc blade 664 contacts the edge of the guide hopper 74, so that the arc blade 664 is pressed, and under the support of the connecting rod 662, the arc blade 664 drives the elliptical elastic ring 665 to rotate toward the position close to the cylinder 64, and the elliptical elastic ring 665 is compressed, and the arc blade 664 is separated from the edge of the guide hopper 74, and the elastic force of the elliptical elastic ring 665 is used to make the arc blade 664 rotate in the opposite direction to reset, so that the arc blade 664 swings back and forth, and uses the fishtail swinging method to increase the stirring direction of the wastewater;

[0069] When wastewater enters the slag storage box 71 from the liquid inlet square pipe 72, under the impact of the wastewater fluid, and by utilizing the rotation support of the connecting round roller 752, the paddle 753 drives the brush 754 to rotate together, and under the flow of wastewater, the suspended matter filtered by the filter residue net 751 is not easy to flow back;

[0070] When the wastewater treatment is completed, the liquid treated in the treatment tank 2 can be discharged and recovered through the liquid outlet pipe 5, and the bottom cover of the slag storage box 71 can be opened to clean out the impurities filtered by the filter residue net 751.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
