Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to a novel environmentally friendly wastewater treatment device. Background Technology

[0002] Wastewater, or urban domestic sewage, mainly consists of scum, organic matter, heavy metals, and some chemical products. Organic matter primarily includes sugars, oils, and some proteins; heavy metals mainly include sodium chloride, iron ions, and calcium ions; and chemical products are mainly nitrogen- and phosphorus-containing chemicals that can pollute the environment. These pollutants interact and cause severe water pollution, affecting residents' work and lives and causing great inconvenience. It not only eutrophicates water bodies but also causes nitrogen and phosphorus pollution, leading to phenomena such as cyanobacterial blooms. Furthermore, urban domestic sewage is toxic. If it flows directly into water sources without strict treatment, it could lead to contaminated wastewater being consumed by humans, causing poisoning and seriously endangering public safety. Currently, some wastewater treatment plants are equipped with integrated wastewater treatment equipment. This equipment is energy-saving and environmentally friendly. To improve wastewater treatment quality, some chemicals are added during the treatment process to react with the wastewater, thereby improving treatment efficiency.

[0003] The prior art (publication number: CN 219907284 U) includes a treatment device body, the inner wall of which is provided with a sedimentation chamber; a mixing structure, the inner top wall of which is installed with a mixing structure, the inner wall of which is installed with a first motor, the bottom of which is movably installed with an agitator shaft, the output end of which is installed through the inner wall of the agitator shaft, the outer wall of which is installed with multiple sets of agitator blades, the top of which is installed with a box, the inner wall of which is installed with a flocculation chamber, the inner wall of which is filled with flocculant, the inner bottom wall of which is installed with a first water pump, the inlet end of which extends through the inner wall of the flocculation chamber, and the outlet end of which extends to the sedimentation chamber.

[0004] Although the aforementioned patent can improve the treatment efficiency of the wastewater treatment device by installing a mixing structure, it has the following drawbacks: the flocculant can only be sprayed onto the surface of the wastewater. In order to make the flocculant evenly distributed in all layers of the wastewater, it is necessary to stir for a long time. The long stirring time increases the wastewater treatment cycle and reduces the treatment efficiency, so further improvement is needed. Therefore, a new type of environmentally friendly wastewater treatment device is proposed. Utility Model Content

[0005] The main objective of this invention is to provide a novel environmentally friendly wastewater treatment device that can effectively solve the problems in the background technology.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A novel environmentally friendly wastewater treatment device includes a tank. Two first valve pipes, arranged vertically, are fixedly connected to the right side of the outer surface of the tank. A second valve pipe is fixedly connected to the left side of the outer surface of the tank. A chemical tank and a pump are installed on the upper left side of the tank. The tank has a first cavity and a second cavity arranged sequentially from top to bottom. A conveying device is installed in the first cavity. An electric valve pipe is fixedly connected to the upper wall of the second cavity and extends into the first cavity. A filter screen is installed in the second cavity.

[0008] Preferably, the conveying device includes a connecting rod disposed in the first cavity, the upper end of the connecting rod extending to the upper side of the tank, and a plurality of stirring blades installed on the outer surface of the connecting rod, the lower ends of the plurality of stirring blades being fixedly connected to a plurality of nozzles.

[0009] Preferably, both the connecting rod and the stirring blade are hollow structures, and the connecting rod and the stirring blade are connected.

[0010] Preferably, the connecting rod is rotatably connected to the tank body.

[0011] Preferably, a motor is installed at the upper end of the tank, and a first gear is fixedly connected to the output end of the motor. The first gear is meshed with a second gear, and the second gear is fixedly sleeved on the upper part of the outer surface of the connecting rod.

[0012] Preferably, a rotary joint is installed at the upper end of the connecting rod, the suction end of the pump body extends into the medicine tank, and the discharge end of the pump body is connected to the rotary joint.

[0013] Preferably, the first valve tubes all extend into the second cavity, with the upper first valve tube located above the filter screen.

[0014] Preferably, the second valve tube extends into the first cavity.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting up a conveying device, flocculant can be delivered into the sewage. During use, the pump body is controlled to deliver flocculant into the connecting rod. Since the nozzle is immersed in the sewage, the flocculant flows out from the nozzle through the stirring blades, so that the flocculant can flow evenly to all parts of the sewage, reducing the subsequent stirring time, reducing the sewage treatment cycle, and improving the treatment efficiency.

[0017] 2. By setting up a motor, a first gear, and a second gear to work together, the conveying device can be driven to rotate. In use, the motor drives the first gear to rotate, the first gear drives the second gear to rotate, and the second gear drives the connecting rod, stirring blades, and nozzles to rotate. When the nozzles can rotate, the flocculant can be evenly sprayed onto all directions and layers of the sewage, ensuring that impurities at all depths of the sewage can be fully treated, making the flocculation process faster, thereby accelerating the entire sewage treatment cycle and improving treatment capacity.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figures 1-4 As shown, a novel environmentally friendly wastewater treatment device includes a tank 1. Two first valve pipes 3 are fixedly and interspersed on the right side of the outer surface of the tank 1, and a second valve pipe 4 is fixedly and interspersed on the left side of the outer surface of the tank 1. The second valve pipe 4 is used to transport wastewater. A chemical tank 5 and a pump body 6 are installed on the upper left side of the tank 1. The chemical tank 5 is used to store flocculant. The interior of the tank 1 has a first cavity 8 and a second cavity 9 arranged sequentially from top to bottom. A conveying device 10 is installed in the first cavity 8. An electric valve pipe 11 is fixedly and interspersed on the upper wall of the second cavity 9, and the electric valve pipe 11 extends into the first cavity 8. A filter screen 12 is installed in the second cavity 9. Two observation windows 2 are installed on the tank 1 for easy observation of the first cavity 8 and the second cavity 9.

[0027] The conveying device 10 is used to transport flocculant into the wastewater. The conveying device 10 includes a connecting rod 101, which is disposed in the first cavity 8. The upper end of the connecting rod 101 extends to the upper side of the tank 1. Several stirring blades 102 are installed on the outer surface of the connecting rod 101. Several nozzles 103 are fixedly connected to the lower ends of the stirring blades 102. The connecting rod 101 and the stirring blades 102 are hollow structures and are connected to each other. In use, the wastewater is transported into the first cavity 8 through the second valve pipe 4, the flocculant is poured into the chemical tank 5, and the pump body 6 is controlled to transport the flocculant into the connecting rod 101. Since the nozzles 103 are immersed in the wastewater, the flocculant flows out from the nozzles 103 through the stirring blades 102, so that the flocculant can flow evenly to all parts of the wastewater, reducing the subsequent stirring time, reducing the wastewater treatment cycle, and improving the treatment efficiency.

[0028] In addition, to ensure that the flocculant is evenly sprayed onto all directions and layers of the wastewater, and that impurities at all depths of the wastewater are fully treated, the connecting rod 101 is rotatably connected to the tank 1 via a bearing. A motor 13 is installed at the upper end of the tank 1, and a first gear 14 is fixedly connected to the output end of the motor 13. The first gear 14 meshes with a second gear 15, which is fixedly sleeved on the upper part of the outer surface of the connecting rod 101. In use, the motor 13 is controlled to drive the first gear 14 to rotate, which in turn drives the second gear 15 to rotate. The second gear 15 drives the connecting rod 101, the stirring blade 102, and the nozzle 103 to rotate. When the nozzle 103 can rotate, the flocculant can be evenly sprayed onto all directions and layers of the wastewater, ensuring that impurities at all depths of the wastewater are fully treated, making the flocculation process faster, thereby accelerating the entire wastewater treatment cycle and improving treatment capacity.

[0029] In order to deliver the flocculant into the rotating connecting rod 101, a rotary joint 7 is installed at the upper end of the connecting rod 101, the suction end of the pump body 6 extends into the medicine tank 5, and the discharge end of the pump body 6 is connected to the rotary joint 7.

[0030] The first valve pipe 3 extends into the second chamber 9. The upper first valve pipe 3 is located above the filter screen 12. The second valve pipe 4 extends into the first chamber 8. After the flocculant and sewage are mixed, the electric valve pipe 11 is opened, and the sewage enters the second chamber 9. The flocculent remains above the filter screen 12, and the sewage flows to the bottom of the second chamber 9. The pre-treated sewage is discharged through the lower first valve pipe 3, and the upper first valve pipe 3 is used to discharge the flocculent on the filter screen 12 during subsequent cleaning.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
