Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment equipment, and in particular to a centralized municipal sewage treatment device. Background Art

[0002] The floating island module (i.e. artificial floating island) uses the principle of ecological engineering to degrade the content of COD, nitrogen, phosphorus, etc. in water, and has a particularly significant effect on purifying eutrophic water. Therefore, it is widely used in centralized municipal sewage treatment.

[0003] However, the floating island assembly in the prior art usually does not have a watering mechanism on the floating island, so that it is impossible to water the plants on the floating island when the temperature is high, making the plants on the floating island easily burned by the scorching sun, thereby affecting the purification effect.

[0069] like Figure 1-16 As shown, the present invention provides a municipal sewage centralized treatment device, including a sewage centralized treatment tank and a floating island assembly arranged in the sewage centralized treatment tank, and the floating island assembly includes a floating island 100 and an aeration mechanism.

[0070] The floating island 100 can float on the water surface, and plants are planted on the floating island 100. An aeration mechanism is arranged on the floating island 100, and the aeration mechanism includes a water pumping pipe 210, a water pump 220 and an aeration pipe 230.

[0071] The water pump 220 is disposed on the floating island 100, and the water pump 220 is fixedly connected to the floating island 100. The water pumping pipe 210 is disposed at the bottom of the floating island 100, and the water outlet end of the water pumping pipe 210 is connected and communicated with the water inlet end of the water pump 220. The aeration pipe 230 is disposed longitudinally on the top of the floating island 100, and the aeration pipe 230 is fixedly connected to the floating island 100, and the water inlet end of the aeration pipe 230 is connected and communicated with the water outlet end of the water pump 220.

[0072] In working state, the water pump 220 applies pressure to the water in the treatment pool, so that the water enters the aeration pipe 230 through the water pumping pipe 210, and finally sprays out from the top of the aeration pipe 230, lifting the water so that the water contacts with the air, thereby achieving the purpose of increasing aeration and improving the dissolved oxygen content in the water.

[0073] Preferably, a filter device 260 is provided at the water inlet end of the water pumping pipe 210 to prevent impurities in the water from entering the water pumping pipe 210 .

[0074] like Figure 1, 2 As shown in Figures 3, 7, and 11, the aeration mechanism also includes an aeration plate 240 and a nozzle 250.

[0075] The aeration plate 240 is arranged at the water outlet end of the aeration tube 230, and a plurality of aeration plates 240 are arranged, and the plurality of aeration plates 240 are evenly arranged around the axis of the aeration tube 230. The nozzle 250 is arranged at the water outlet end of the aeration tube 230, and the nozzle 250 is fixedly connected to the aeration tube 230. In the working state, the nozzle 250 sprays water toward the aeration plate 240, and the water hits the aeration plate 240, so that the water is dispersed due to hitting the aeration plate 240, thereby increasing the contact area between water and air, thereby achieving the purpose of improving the aeration effect.

[0076] like Figure 1 , 2 As shown in Figures 3, 7, and 11, in this embodiment, the nozzle 250 has a plurality of spray holes, and the plurality of spray holes are evenly distributed around the axis of the aeration pipe 230.

[0077] like Figure 1 , 2 As shown in Figures 3, 7 and 11, the floating island assembly also includes a sprinkler mechanism, which is used to sprinkle water on the plants on the floating island 100 when the temperature exceeds a preset temperature, wherein the sprinkler mechanism includes a mounting seat 310, a sprinkler pipe 320, a first drive structure and a second drive structure.

[0078] The mounting seat 310 is sleeved on the lower end of the aeration tube 230. The inner side wall of the mounting seat 310 is sealed with the outer side wall of the aeration tube 230. The mounting seat 310 is movably connected to the aeration tube 230. The inner side wall of the mounting seat 310 is provided with a water guide groove 311. The lower end of the aeration tube 230 is correspondingly provided with a water outlet 231. A watering pipe 320 is fixedly provided on the mounting seat 310. The watering pipe 320 is fixedly connected to the mounting seat 310, and the watering pipe 320 is communicated with the water guide groove 311. Figure 5 , 9 As shown in FIG. 13 , the sprinkler pipe 320 is connected to the water guide groove 311 through the water guide hole 312 .

[0079] The mounting seat 310 has a first position and a second position. When the mounting seat 310 is in the first position, the water guide groove 311 and the water outlet hole 231 are staggered with each other, so that the water in the aeration tube 230 cannot enter the water guide groove 311 through the water outlet hole 231; when the mounting seat 310 is in the second position, the water guide groove 311 and the water outlet hole 231 correspond to each other, so that the water in the aeration tube 230 can enter the water guide groove 311 through the water outlet hole 231, and finally be sprayed out through the sprinkler pipe 320.

[0080] The first driving structure is in transmission connection with the mounting seat 310, and the first driving structure is used to drive the mounting seat 310 to rotate. In the working state, the first driving structure drives the mounting seat 310 to rotate, and the mounting seat 310 rotates with the sprinkler pipe 320, thereby achieving the purpose of increasing the spray range.

[0081] The second driving structure is in driving connection with the mounting seat 310 , and is used to drive the mounting seat 310 to perform reciprocating linear motion between the first position and the second position.

[0082] When watering, the water pump 220 is turned on, and at the same time, the second driving structure drives the mounting seat 310 from the first position to the second position so that the water guide groove 311 corresponds to the water outlet hole 231. During aeration, the water in the aeration pipe 230 enters the water guide groove 311 through the water outlet hole 231, and is finally sprayed out through the sprinkler pipe 320 to achieve the purpose of watering the plants on the floating island 100.

[0083] During this process, the first driving structure drives the mounting seat 310 to rotate, and the mounting seat 310 rotates with the sprinkler pipe 320, thereby achieving the purpose of increasing the spraying range.

[0084] like Figure 1 , 2 As shown in Figures 3, 7 and 11, the first driving structure includes a rotating seat 330 and a driving seat 340.

[0085] The rotating seat 330 is sleeved on the aeration tube 230, and the rotating seat 330 is rotatably connected to the aeration tube 230, so that the rotating seat 330 can only rotate around the axis of the aeration tube 230, but cannot move along the axis of the aeration tube 230. Among them, a plurality of aeration plates 240 are fixedly connected to the rotating seat 330. Figure 1 , 2 As shown in Figures 3, 7 and 11, the aeration plate 240 is fixedly connected to the rotating seat 330 via a support frame 331.

[0086] In the working state, water sprayed from the nozzle 250 hits the aeration plate 240, thereby applying a force to the aeration plate 240 to form a torque to drive the rotating seat 330 to rotate.

[0087] The driving seat 340 is sleeved on the aeration tube 230 and the mounting seat 310 , and the driving seat 340 is rotatably connected to the aeration tube 230 , so that the driving seat 340 can only rotate around the axis of the aeration tube 230 but cannot move along the axis of the aeration tube 230 .

[0088] The driving seat 340 is in transmission connection with the rotating seat 330, so that the rotating seat 330 can transmit power to the driving seat 340, thereby driving the driving seat 340 to rotate. Figure 5 , 6As shown in FIGS. 9 , 10 , 13 , and 14 , a transmission rod 350 is provided between the driving seat 340 and the rotating seat 330 , and both ends of the transmission rod 350 are connected to the driving seat 340 and the rotating seat 330 , respectively.

[0089] The driving seat 340 is in transmission connection with the mounting seat 310 to drive the mounting seat 310 to rotate. Figure 5 , 10 As shown, the outer side wall of the mounting seat 310 is provided with a guide groove 313, the length direction of the guide groove 313 extends along the axis direction of the aeration pipe 230, and the inner side wall of the rotating seat 330 is correspondingly provided with a driving part 341 adapted to the guide groove 313. In the working state, through the cooperation of the driving part 341 and the guide groove 313, the driving seat 340 can transmit power to the mounting seat 310 to drive the mounting seat 310 to rotate.

[0090] When in use, when watering, the water sprayed from the nozzle 250 hits the aeration plate 240, thereby applying a force to the aeration plate 240 to drive the aeration plate 240 to rotate. The aeration plate 240 transmits power to the mounting seat 310 through the rotating seat 330, the transmission rod 350 and the driving seat 340, thereby driving the mounting seat 310 to rotate.

[0091] The first driving structure provided in this embodiment has a simple structure and a reasonable design, and utilizes the force of water hitting the aeration plate 240 to drive the mounting seat 310 to rotate, thereby saving power.

[0092] like Figure 5 As shown, the second driving structure includes a first electric push rod 360. The first electric push rod 360 is fixedly arranged on the floating island 100. And the power output shaft of the first electric push rod 360 is transmission-connected with the mounting seat 310. In this embodiment, the power output shaft of the first electric push rod 360 abuts against the mounting seat 310. In the working state, the first electric push rod 360 extends, thereby applying a driving force to the mounting seat 310 through the power output shaft to drive the mounting seat 310 from the first position to the second position. In the non-working state, the first electric push rod 360 contracts, and under the action of gravity, the mounting seat 310 moves from the second position to the first position.

[0093] like Fig. 9 As shown, the second driving structure includes a permanent magnet 370 and an electromagnet 380 .

[0094] The permanent magnet 370 is fixedly embedded in the bottom of the mounting seat 310, and the electromagnet 380 is fixedly arranged on the floating island 100, and the magnetism of the electromagnet 380 on the side opposite to the permanent magnet 370 is different. In the working state, the electromagnet 380 is energized, thereby generating a magnetic repulsion force between the electromagnet 380 and the permanent magnet 370, and under the action of the magnetic repulsion force, the mounting seat 310 is driven from the first position to the second position; in the non-working state, the electromagnet 380 is powered off, and under the action of gravity, the mounting seat 310 drops from the second position to the first position.

[0095] like Figure 13-16 As shown, the second driving structure includes a guide groove 313 and a driving part 341. The guide groove 313 is inclined. When the rotating seat 330 rotates, the driving part 341 cooperates with the guide groove 313, and the rotating seat 330 applies a force to the mounting seat 310 to drive the mounting seat 310 to rotate around the axis of the aeration pipe 230, and also drives the mounting seat 310 to move from the first position to the second position.

[0096] Optionally, the second driving structure further includes a first elastic element 390, the two ends of which are respectively connected to the driving seat 340 and the mounting seat 310, and in a natural state, the first elastic element 390 applies elastic force to the mounting seat 310, so that the mounting seat 310 has a tendency to move from the second position to the first position. The first elastic element 390 can be any elastic device that can apply elastic force to the mounting seat 310. In this embodiment, the first elastic element 390 is a spring.

[0097] like Figure 6 , 10 As shown in Figure 14, the floating island assembly also includes a locking mechanism, which is arranged on the mounting seat 310 and the aeration pipe 230, and the locking mechanism has a locked state and an unlocked state, wherein when the locking mechanism is in the locked state, the locking mechanism keeps the mounting seat 310 in the second position so that the mounting seat 310 cannot move from the second position to the first position; when the locking mechanism is in the unlocked state, the locking mechanism cannot lock the mounting seat 310, so that the mounting seat 310 can move from the second position to the first position.

[0098] like Figure 6 , 10 As shown in FIG. 14 , the locking mechanism includes a push plate 410 , a locking groove 420 and a second elastic element 430

[0099] The side wall of the aeration tube 230 is provided with a mounting hole 232, and the mounting hole 232 is communicated with the aeration tube 230. The push plate 410 is slidably arranged in the mounting hole 232, and the outer side wall of the push plate 410 is sealed with the inner side wall of the mounting hole 232. A locking rod 411 is provided on the side of the push plate 410 away from the axis of the aeration tube 230, and the locking rod 411 is fixedly connected to the push plate 410.

[0100] The push plate 410 has a third position and a fourth position. When the push plate 410 is in the third position, the push rod retracts into the outer side wall of the aeration tube 230 . When the push plate 410 is in the fourth position, the push rod extends beyond the outer side wall of the aeration tube 230 .

[0101] The locking groove 420 is formed on the inner side wall of the mounting seat 310 , and the locking groove 420 is annular.

[0102] The second elastic element 430 is sleeved on the push rod, and the two ends of the second elastic element 430 are respectively in contact with the inner side wall of the mounting cavity and the push plate 410, and in a natural state, the second elastic element 430 applies elastic force to the push plate 410, so that the push plate 410 is driven to move from the fourth position to the third position. The second elastic element 430 can be any elastic device that can apply elastic force to the push plate 410. In this embodiment, the second elastic element 430 is a spring.

[0103] When spraying water, the mounting seat 310 is driven to the second position, so that the locking groove 420 corresponds to the locking rod 411, and the water in the aeration pipe 230 enters the mounting hole 232 to exert pressure on the push plate 410, so that the push plate 410 overcomes the elastic force of the second elastic element 430 and moves from the third position to the fourth position, so that the locking rod 411 is inserted into the locking groove 420. Under the mutual cooperation of the locking rod 411 and the locking groove 420, the purpose of keeping the mounting seat 310 in the second position is achieved.

[0104] When the water spraying stops, the water pump 220 is turned off, and under the action of the elastic force of the second elastic element 430, the push plate 410 moves from the fourth position to the third position, thereby releasing the lock on the mounting seat 310, and then allowing the mounting seat 310 to move from the second position to the first position.

[0105] In this embodiment, a locking mechanism is provided to keep the mounting base 310 in the second position when spraying water. There is no need for the electromagnet 380 and the first electric push rod 360 to be energized all the time to keep the mounting base 310 in the second position. That is, after the mounting base 310 is driven to the second position, the electromagnet 380 can be powered off, and the first electric push rod 360 can be retracted and then powered off, thereby achieving the purpose of saving electric energy. At the same time, during the process of spraying water, the mounting base 310 will not move from the second position to the first position under the action of the elastic force of the first elastic element 390.

[0106] like Figure 3 , 4 As shown in Figures 5, 7, 8, 9, 11, 12, and 13, the floating island assembly also includes a locking mechanism, which is arranged on the driving seat 340 and the floating island 100, and the locking mechanism has a locked state and an unlocked state. When the locking mechanism is in the locked state, the locking mechanism locks the driving seat 340 so that the driving seat 340 cannot rotate, and then the aeration plate 240 cannot rotate, so as to achieve the purpose of increasing the impact force between the water sprayed by the nozzle 250 and the aeration plate 240, so that when the water hits the aeration plate 240, it can be hit more scattered, thereby achieving the purpose of improving the aeration effect; when the locking mechanism is in the unlocked state, the locking mechanism releases the lock on the driving seat 340 so that the driving seat 340 can rotate, so that when the water sprayed by the nozzle 250 hits the aeration plate 240, the aeration plate 240 can rotate, and the aeration plate 240 transmits power to the driving seat 340 through the rotating seat 330, so as to achieve the purpose of driving the mounting seat 310 to move.

The locking slide 520 is arranged on one side of the driving seat 340 and is slidably connected to the floating island 100. The locking slide 520 is fixedly connected to the power output shaft of the second electric push rod 510. The locking slide 520 has a fifth position and a sixth position. Among them, the side wall of the locking slide 520 facing the driving seat 340 is provided with a first limiting tooth structure 521, and the outer side wall of the driving seat 340 is correspondingly provided with a second limiting tooth structure 342. When the locking slide 520 is in the fifth position, the locking slide 520 is separated from the driving seat 340 so that the locking mechanism is in an unlocked state; when the locking slide 520 is in the sixth position, the first limiting tooth structure 521 and the second limiting tooth structure 342 cooperate with each other to lock the driving seat 340 so that the driving seat 340 cannot rotate.

[0109] Optionally, a solar power generation device, a storage battery, a temperature sensor, etc. are also provided on the floating island 100. The solar power generation device is used to convert solar energy into electrical energy, thereby supplying power to electrical components such as the water pump 220, the first electric push rod 360, the second electric push rod 510, the temperature sensor, and the electromagnet 380. The storage battery is used to store the electrical energy generated by the solar power generation device, and at the same time, supply power to electrical components such as the water pump 220, the first electric push rod 360, the second electric push rod 510, the temperature sensor, and the electromagnet 380.

[0110] The temperature sensor is used to detect the external temperature. When the temperature exceeds a preset value, the watering mechanism is controlled to spray water on the plants on the floating island 100 to prevent the plants from withering due to high temperature.
