Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a novel energy-saving and environmentally friendly wastewater treatment device. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering. It is also increasingly entering the daily lives of ordinary people. With the awakening of public environmental awareness, the level of concern for water pollution has reached an unprecedented level. my country has increased its investment in urban infrastructure construction and environmental protection, and strengthened comprehensive environmental management, thereby effectively controlling the total amount of pollutant emissions and improving the environmental quality of some regions and cities. However, conventional wastewater treatment devices usually use filter screens for pre-filtration to separate larger particles. The filter screens need to be cleaned frequently during use, and frequent replacement or cleaning of the filter screens is not only troublesome but also greatly affects the wastewater treatment process.

[0003] To address the aforementioned issues, Chinese Patent No. CN212476351 U, entitled "A Novel Energy-Saving and Environmentally Friendly Wastewater Treatment Device," utilizes a separation tank with a narrow upper section and a wide lower section, along with a mixing mechanism, to mix flocculant and wastewater. The wastewater mixed with flocculant is then guided by a guide fluid to converge in the center, facilitating the settling of sediment into the lower settling tank. Furthermore, the design of a manifold and overflow outlet allows purified water to flow out, while the sediment remains in the separation tank, achieving solid-liquid separation. However, this wastewater treatment device still has certain drawbacks in use. For example, when it is necessary to clean the sediment in the settling tank, the equipment must be shut down, affecting wastewater treatment efficiency. Utility Model Content

[0024] This application provides a novel energy-saving and environmentally friendly wastewater treatment device. This device, through the installation of a blocking component, increases the residence time of wastewater and flocculant within the guide funnel, allowing the flocculant to fully contact the pollutants and form larger, denser flocs. Furthermore, the device allows for switching of the settling tank via a switching component, thereby improving wastewater treatment efficiency. The following provides a detailed description of this novel energy-saving and environmentally friendly wastewater treatment device. It should be noted that the order of description in the following embodiments is not intended to limit the preferred order of the embodiments.

[0025] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0026] Please see Figure 1-6 This embodiment provides a novel energy-saving and environmentally friendly wastewater treatment device, comprising: a fixed support 1, a treatment tank 2 fixedly installed on the top of the fixed support 1, and two settling tanks 7 at the bottom of the fixed support 1; a switching assembly located at the bottom of the fixed support 1, the switching assembly comprising: a guide pipe 6, a diversion pipe a601, a diversion pipe b603, a solenoid valve a605, a solenoid valve b606, a connecting water pipe 702, and a water pipe connecting cover 703; and a sealing assembly located inside the treatment tank 2, the sealing assembly comprising: a liquid level sensor 301, a microcontroller 302, a guide funnel 205, a rubber sealing block 204, and an electric telescopic rod 202.

[0027] The bottom of the treatment tank 2 is fixedly connected to a guide pipe 6. A diversion pipe b603 is fixedly connected to one side of the guide pipe 6. A hose b604 is fixedly connected to one end of the diversion pipe b603. A diversion pipe a601 is fixedly connected to one end of the guide pipe 6. A hose a602 is fixedly connected to one end of the diversion pipe a601. A water pipe connection cap 703 is fixedly connected to one end of both hose a602 and hose b604. The tops of the two settling tanks 7 are bolted to cover plates 701. Sealing rings are fixedly installed at the bottom of the two cover plates 701. A connecting water pipe 702 is fixedly connected to the top of the two cover plates 701. A solenoid valve a605 is installed on the guide pipe 6. A solenoid valve b606 is installed on the diversion pipe b603. The connecting water pipe 702 has an external thread on the outside. The water pipe connection cap 703 has an internal thread that matches the external thread on the outside of the connecting water pipe 702. The water pipe connection cap 703 and the connecting water pipe 702 are threaded together.

[0028] In use, wastewater is supplied to the mixing tank 3 through the inlet pipe 5, and flocculant is supplied to the mixing tank 3 through the flocculant inlet pipe 501. The flocculant and wastewater simultaneously impact the stirring plate 401. Since the two ends of the rotating shaft 4 are connected to the inner wall of the mixing tank 3 via bearings, the stirring plate 401 rotates when subjected to force, thus mixing the flocculant and wastewater together. The mixture then flows to the bottom of the guide funnel 205 and gradually accumulates, thereby increasing the reaction time between the flocculant and wastewater. When the water level inside the guide funnel 205 reaches a certain level and comes into contact with the level sensor 301, the level sensor 301 generates an electrical signal, which is transmitted to the microcontroller 3. 02. After receiving the electrical signal, the microcontroller 302 controls the two support plates 203 to retract, thereby causing the rubber sealing block 204 to move down and open the bottom of the guide funnel 205. At this time, the water inside the guide funnel 205 will flow into the treatment chamber 201. When the water inside the guide funnel 205 flows into the treatment chamber 201, the water level inside the guide funnel 205 drops. The liquid level sensor 301 generates an electrical signal again and transmits it to the microcontroller 302, thereby causing the microcontroller 302 to control the two electric telescopic rods 202 to extend, thereby resetting the rubber sealing block 204 and sealing the guide funnel 205 to block the subsequent sewage and flocculant.

[0029] Furthermore, the wastewater mixed with flocculant inside the guide funnel 205 enters the treatment chamber 201 when the bottom of the guide funnel 205 opens, and then enters the settling tank 7 through the guide pipe 6, the diversion pipe b603 and the hose b604. The precipitate formed at this time also enters the settling tank 7 through the guide pipe 6, the diversion pipe b603 and the hose b604 and settles inside the settling tank 7. As the treated wastewater continues to enter the treatment chamber 201 and the settling tank 7, the treated wastewater will gradually accumulate in the treatment chamber 201 and the settling tank 7. Therefore, when the water level in the treatment chamber 201 is higher than the drain pipe 502, the treated wastewater will be discharged through the drain pipe 502, thereby achieving solid-liquid separation.

[0030] The treatment box 2 has two drain pipes 502 fixedly connected to both sides, and a mixing box 3 fixedly connected to the top of the treatment box 2. A rotating shaft 4 is installed inside the mixing box 3, with both ends of the shaft 4 connected to the inner wall of the mixing box 3 via bearings. One-way valves are installed on both drain pipes 502, and filter screens 503 are fixedly installed on the ends of both drain pipes 502 closest to the treatment box 2. A microcontroller 302 is installed inside the treatment box 2, and a treatment chamber 201 is formed inside the treatment chamber 201. A support plate 20 is installed inside the treatment chamber 201. 3. Two electric telescopic rods 202 are fixedly installed inside the treatment box 2. A flocculant feed pipe 501 is fixedly connected to the top of the mixing box 3. A water inlet pipe 5 is fixedly connected to the top of the mixing box 3. Multiple stirring plates 401 are fixedly connected to the outside of the rotating shaft 4. A liquid level sensor 301 is fixedly installed on one side of the inner wall of the mixing box 3. A rubber sealing block 204 is fixedly installed on the top of the support plate 203. A flow guide funnel 205 is fixedly connected inside the mixing box 3. The tops of the two electric telescopic rods 202 are fixedly connected to the support plate 203.

[0031] When the sediment inside the settling tank 7 reaches a certain level, the solenoid valve b606 can be closed and the solenoid valve a605 opened via the control panel. This changes the flow direction of the water inside the treatment chamber 201, allowing the treated water and sediment to flow through the diversion pipe a601 and the hose a602 into the settling tank 7 at one end of the hose a602. Then, the water pipe connection cap 703 at one end of the hose b604 can be rotated to unscrew the water pipe 702, thus disconnecting the water pipe 702 from the water pipe connection cap 703. This allows the settling tank 7 to be removed. Next, the bolts on the cover plate 701 can be unscrewed, and the water pipe 702 can be opened to clean the sediment inside the settling tank 7.

[0032] In addition, the liquid level sensor 301 can be model YW-01. The liquid level sensor 301 is composed of conductive and insulating materials. When the liquid comes into contact with the metal part, a conductive path is formed, the resistance value of the conductive material changes, an electrical signal is generated, and it is transmitted to the microcontroller 302 to determine the liquid level height. This solution does not make any improvements to the circuit or program of the liquid level sensor 301, so the circuit and signal connection relationship of the liquid level sensor 5 will not be described in detail.

[0033] The working principle is as follows:

[0034] In operation, wastewater is supplied to the mixing tank 3 through the inlet pipe 5, and flocculant is supplied to the mixing tank 3 through the flocculant inlet pipe 501. The flocculant and wastewater simultaneously impact the mixing plate 401. Since the two ends of the rotating shaft 4 are connected to the inner wall of the mixing tank 3 via bearings, the mixing plate 401 rotates when subjected to force, thus mixing the flocculant and wastewater together. The mixture then flows to the bottom of the guide funnel 205 and gradually accumulates, increasing the reaction time between the flocculant and wastewater. When the water level inside the guide funnel 205 reaches a certain level and comes into contact with the level sensor 301, the level sensor 301 generates an electrical signal, which is transmitted to the microcontroller 3. 02. After receiving the electrical signal, the microcontroller 302 controls the two support plates 203 to retract, thereby causing the rubber sealing block 204 to move down and open the bottom of the guide funnel 205. At this time, the water inside the guide funnel 205 will flow into the treatment chamber 201. When the water inside the guide funnel 205 flows into the treatment chamber 201, the water level inside the guide funnel 205 drops. The liquid level sensor 301 generates an electrical signal again and transmits it to the microcontroller 302, thereby causing the microcontroller 302 to control the two electric telescopic rods 202 to extend, thereby resetting the rubber sealing block 204 and sealing the guide funnel 205 to block the subsequent sewage and flocculant.

[0035] Furthermore, the wastewater mixed with flocculant inside the guide funnel 205 enters the treatment chamber 201 when the bottom of the guide funnel 205 opens, and then enters the settling tank 7 through the guide pipe 6, the diversion pipe b603 and the hose b604. The precipitate formed at this time also enters the settling tank 7 through the guide pipe 6, the diversion pipe b603 and the hose b604 and settles inside the settling tank 7. As the treated wastewater continues to enter the treatment chamber 201 and the settling tank 7, the treated wastewater will gradually accumulate in the treatment chamber 201 and the settling tank 7. Therefore, when the water level in the treatment chamber 201 is higher than the drain pipe 502, the treated wastewater will be discharged through the drain pipe 502, thereby achieving solid-liquid separation.

[0036] When the sediment inside the settling tank 7 reaches a certain level, the solenoid valve b606 can be closed and the solenoid valve a605 opened via the control panel. This changes the flow direction of the water inside the treatment chamber 201, allowing the treated water and sediment to flow through the diversion pipe a601 and the hose a602 into the settling tank 7 at one end of the hose a602. Then, the water pipe connection cap 703 at one end of the hose b604 can be rotated to unscrew the water pipe 702, thus disconnecting the water pipe 702 from the water pipe connection cap 703. This allows the settling tank 7 to be removed. Next, the bolts on the cover plate 701 can be unscrewed, and the water pipe 702 can be opened to clean the sediment inside the settling tank 7.
