DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1 to 10 , a green cold energy water purification device for use in agricultural and pastoral areas, comprising a sedimentation tank 1 and a cold energy water purification tank 2, the sedimentation tank 1 and the cold energy water purification tank 2 being connected, and a sedimentation mechanism for treating raw water is provided in the sedimentation tank 1; specifically, the sedimentation mechanism is composed of a first drive structure 3, a second drive structure 4, an infusion structure 5 and an aeration structure. It should be noted that the sedimentation tank 1 and the cold energy water purification tank 2 are wrapped with a layer of thermal insulation material, such as a polyurethane foam board, which has good thermal insulation properties and can effectively reduce heat loss. The pretreated water enters the cold energy water purification tank 2, giving priority to utilizing the natural low temperature in winter or the temperature difference between day and night, and simulating the freezing process of the lake from top to bottom through a vacuum insulation layer.

[0024] It should be noted that the inner bottom surface of the sedimentation tank 1 is conical, and the conical bottom surface gradually reduces the lower space of the sedimentation tank 1. The flow rate of sewage will gradually decrease during the flow process. According to Stokes' law, the sedimentation rate of particles is related to the viscosity of the liquid and the particle size of the particles. The reduction in flow rate is conducive to the suspended particles in the sewage to settle to the bottom of the cone more quickly under the action of gravity, thereby improving the sedimentation efficiency. Since the sludge is concentrated at the bottom of the cone, when the sludge needs to be discharged, the sludge can be more conveniently discharged from the sedimentation tank 1 through the sewage outlet set at the bottom of the cone, thereby improving the efficiency and thoroughness of sewage discharge, and helping to keep the sedimentation tank 1 clean, thereby ensuring the normal operation of the sewage treatment system.

[0025] In this embodiment, the first driving structure 3 includes a water pipe 301 fixed to the upper surface of the sedimentation tank 1, and a water wheel 302 is rotatably arranged in the water pipe 301. A driving shaft 303 connected to the internal bearing of the sedimentation tank 1 is fixed at one end of the water wheel 302, and an eccentric wheel 304 cooperating with the second driving structure 4 is fixed at one end of the driving shaft 303, and the other end of the driving shaft 303 is connected to the aeration structure; the water flow impact force when the raw water enters the sedimentation tank 1 is used to drive the water wheel 302, and then drive the entire sedimentation mechanism to work. There is no need to set up an additional power source, which realizes full utilization of energy and reduces the operating cost of the device. It is suitable for use in areas with relatively limited energy supply such as agricultural and pastoral areas.

[0026] In this embodiment, the second driving structure 4 includes a sleeve 401 fixed to the upper surface of the sedimentation tank 1, and a telescopic member 402 extending outside the sleeve 401 and abutting against the outer surface of the eccentric wheel 304 is provided inside the sleeve 401. A transmission member 403 is provided for rotation inside the sleeve 401, and the telescopic member 402 includes a rotating drum 4021 rotatably mounted inside the sleeve 401. The outer surface of the rotating drum 4021 is sleeved with a telescopic sleeve 4022. The sleeve 401 is provided with a stirring member extending to the interior of the sedimentation tank 1, and the outer surface of the telescopic sleeve 4022 is fixed with a The stirring member is connected to a linkage rod 408, a roller 410 is provided inside the telescopic sleeve 4022, a reciprocating rolling groove 411 for use with the roller 410 is opened inside the rotating drum 4021, and a buffer spring 412 is provided between the telescopic sleeve 4022 and the rotating drum 4021; the stirring member includes a transmission sleeve 405 rotatably installed inside the sleeve 401 and connected to the transmission member 403, a stirring shaft 406 extending to the interior of the sedimentation tank 1 is provided inside the transmission sleeve 405, and an impeller 407 is fixed to the bottom end of the stirring shaft 406.

[0027] Specifically, the interiors of the sleeve 401 and the telescopic sleeve 4022 are both hollow, with the ends of the buffer spring 412 rotatably connected to the top of the rotating cylinder 4021 and the inner top wall of the telescopic sleeve 4022, respectively. The transmission member 403 includes a transmission sleeve 4031 rotatably mounted on the inner side of the sleeve 401. The transmission sleeve 4031 houses planetary gears 4032 and a sun gear 4033. The planetary gears 4032 mesh with the transmission sleeve 4031 and the sun gear 4033, respectively. There are three planetary gears 4032, with the sun gear 4033 located at the center of the transmission sleeve 4031 and the three planetary gears 4032 equidistantly spaced between the sun gear 4033 and the transmission sleeve 4031. A connecting shaft 404 is fixed between the bottom end of the rotating cylinder 4021 and the transmission sleeve 4031. Support shafts 4034 rotatably connected to the inner wall of the sleeve 401 are fixed to the outer surfaces of the three planetary gears 4032.

[0028] It should be noted that the transmission sleeve 405 is fixed to the sun gear 4033, the agitator shaft 406 is splined to the transmission sleeve 405, and a connecting sleeve 409, which is rotatably connected to the agitator shaft 406, is fixed to the end of the linkage rod 408 away from the telescopic sleeve 4022. The top end of the agitator shaft 406 passes through the transmission sleeve 405 and extends into the interior of the rotating drum 4021. A reciprocating rolling groove 411 is arranged around the outer surface of the rotating drum 4021, and the reciprocating rolling groove 411 has a V-shape with two symmetrical front and rear arrangements. The top end of the sleeve 401 is provided with a movable opening for use with the linkage rod 408.

[0029] When the present embodiment is in use, raw water enters the sedimentation tank 1. When passing through the water pipe 301, the water flow impacts the water wheel 302 to rotate, and the water wheel 302 drives the driving shaft 303 to rotate, and the eccentric wheel 304 at one end of the driving shaft 303 rotates and extends accordingly. When the eccentric wheel 304 rotates, it abuts against the outer surface of the telescopic sleeve 4022 in the telescopic member 402, pushing the telescopic sleeve 4022 to reciprocate on the rotating drum 4021. Since the roller 410 rolls in the reciprocating rolling groove 411 provided inside the rotating drum 4021, the rotating drum 4021 rotates, and the buffer spring 412 plays a buffering role to ensure smooth movement; the rotation of the rotating drum 4021 drives the transmission gear sleeve 4031 in the transmission member 403 to rotate through the connecting shaft 404, and the transmission gear sleeve 4031 drives the three planetary gears 4032 to revolve around the sun gear 4033. At the same time, the planetary gears 4032 rotate themselves, and the sun gear 4033 rotates accordingly; The sun gear 4033 drives the transmission sleeve 405 to rotate, and the transmission sleeve 405 drives the stirring shaft 406 to rotate. The impeller 407 at the bottom end of the stirring shaft 406 begins to stir the raw water in the sedimentation tank 1 to promote sedimentation. At the same time, the telescopic sleeve 4022 drives the connecting sleeve 409 to move up and down through the linkage rod 408. Since the stirring shaft 406 and the transmission sleeve 405 are splined, the stirring shaft 406 can move up and down while rotating, further enhancing the stirring effect.

[0030] It should be noted that by driving the impeller 407 to cut the water flow, a vortex is formed around the sewage. The generation of the vortex can reduce the disturbance of the sewage in the sedimentation tank 1 by changing the movement direction and velocity distribution of the water flow, making the sedimentation process more stable and efficient. The impurities in the sedimentation tank 1 can be better settled to the conical inner bottom surface, extending the residence time of the sewage in the sedimentation tank 1, giving the impurities more time to settle, improving the sedimentation efficiency of the sedimentation tank 1, and improving the treatment effect of the entire sewage treatment system.

[0031] In this embodiment, the liquid infusion structure 5 includes a through tube 502 fixed to the upper surface of the sedimentation tank 1. The upper surface of the through tube 502 is fixedly connected to the housing 501. A diaphragm 503 is fixed inside the housing 501. Two check valves 505 are installed inside the through tube 502. A second linkage rod 504 is fixed to the upper surface of the diaphragm 503, extending to the exterior of the housing 501 and fixed to the first linkage rod 408. Liquid infusion tubes 506 are fixed to both ends of the through tube 502, and the ends of the liquid infusion tubes 506 are respectively connected to the liquid storage tank and the aeration structure.

[0032] In this embodiment, the aeration structure includes a blower 6 fixed to the outer surface of the water pipe 301, and the impeller on the blower 6 is connected and fixed to the end of the drive shaft 303 away from the eccentric wheel 304. The aeration structure also includes a spray rack 7 rotatably mounted on the outer surface of the stirring shaft 406, and one of the liquid delivery tubes 506 is fixedly connected to the spray rack 7. Specifically, an air supply pipe 8 is fixed between the spray rack 7 and the blower 6, and a plurality of equidistantly distributed spray holes 71 are provided inside the spray rack 7. The main body of the spray rack 7 is made of stainless steel. The air supply pipe 8 is made of a high-pressure and corrosion-resistant rubber hose, and the two ends of the hose are connected to the blower 6 and the spray rack 7 with quick connectors for easy installation and disassembly. At the same time, a layer of thermal insulation material is wrapped around the outside of the air supply pipe 8 to prevent heat loss and the influence of low temperature on gas transmission. The air supply pipe 8 is a hose, and the liquid delivery tube 506 connected to the spray rack 7 is a corrugated hose. When this embodiment is in use, the rotation of the drive shaft 303 drives the impeller on the blower 6 to rotate, generating airflow, which enters the spray rack 7 through the air supply pipe 8. At the same time, the liquid delivered by the liquid delivery structure 5 also enters the spray rack 7. After the airflow and liquid are mixed, they are sprayed out from a number of equidistantly distributed spray holes 71 inside the spray rack 7, aerating the raw water in the sedimentation tank 1, further promoting the precipitation and reaction of impurities in the raw water.

[0033] The working principle of the above embodiment is: When raw water enters the sedimentation tank 1 and passes through the water pipe 301, the water flow impacts the water wheel 302, causing it to rotate. The water wheel 302 drives the drive shaft 303 to rotate, and the eccentric wheel 304 at one end of the drive shaft 303 rotates accordingly. When the eccentric wheel 304 rotates, it abuts the outer surface of the telescopic sleeve 4022 in the telescopic member 402, pushing the telescopic sleeve 4022 to reciprocate on the rotating drum 4021. As the roller 410 rolls in the reciprocating rolling groove 411 defined inside the rotating drum 4021, the rotating drum 4021 rotates, and the buffer spring 412 acts as a buffer to ensure smooth movement. The rotating drum 4021 rotates through the connecting shaft 404, driving the transmission sleeve 4031 in the transmission member 403 to rotate. The transmission sleeve 4031 drives the three planetary gears 4032 to revolve around the sun gear 4033. At the same time, the planetary gears 4032 rotate themselves, and the sun gear 4033 rotates accordingly. The sun gear 4033 drives the transmission sleeve 405 to rotate, and the transmission sleeve 405 drives the stirring shaft 406 to rotate. The impeller 407 at the bottom end of the stirring shaft 406 begins to stir the raw water in the sedimentation tank 1 to promote sedimentation. At the same time, the telescopic sleeve 4022 drives the connecting sleeve 409 to move up and down through the linkage rod 408. Since the stirring shaft 406 and the transmission sleeve 405 are spline-connected, the stirring shaft 406 can move up and down while rotating, further enhancing the stirring effect. When the telescopic sleeve 4022 moves up and down, the diaphragm 503 is driven to move up and down in the housing 501 through the second linkage rod 504. When the diaphragm 503 moves upward, the lower check valve 505 closes and the upper check valve 505 opens, sucking the liquid in the liquid storage tank, such as flocculant, into the passage 502. When the diaphragm 503 moves downward, the upper check valve 505 closes and the lower check valve 505 opens, and the liquid is transported to the aeration structure through the liquid delivery tube 506. When the drive shaft 303 rotates, its other end drives the impeller on the blower 6 to rotate, generating airflow. The airflow enters the spray rack 7 through the air delivery pipe 8. At the same time, the liquid delivered by the liquid delivery structure 5 also enters the spray rack 7. After the airflow and liquid are mixed, they are sprayed out from a number of equally spaced spray holes 71 inside the spray rack 7, aerating the raw water in the sedimentation tank 1 and further promoting the precipitation and reaction of impurities in the raw water. After sedimentation, stirring, dosing and aeration treatment by the sedimentation mechanism, impurities in the raw water gradually settle to the bottom of the sedimentation tank 1, and the supernatant enters the cold energy water purification tank 2 through the pipeline for further purification treatment.

Any connection method can be implemented as long as it can achieve its beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply.

Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so its specific structural composition and working principle will not be described in detail in this embodiment.
