Description

Technical Field

[0001] The invention belongs to the technical field of cyclone filters, in particular to a cyclone filter for collecting rainwater in a sponge city. Background Art

[0002] A sponge city refers to a city that can adapt to environmental changes and respond to natural disasters like a sponge, absorbing, storing, infiltrating and purifying water when it rains, and "releasing" and utilizing the stored water when needed. Sponge city construction follows the principle of ecological priority, combining natural approaches with artificial measures, and maximizing the accumulation, infiltration and purification of rainwater in cities and villages on the premise of ensuring drainage and flood control safety, promoting the utilization of rainwater resources and the protection of the ecological environment. Rainwater recycling is an important part of building a sponge city. How to remove impurity particles and bacteria in rainwater is the key issue in realizing rainwater reuse. A cyclone filter is a centrifugal separation device, which is generally used for sewage or wastewater treatment. A cyclone filter can separate solid matter such as gravel, dirt, mud, humus, and plants from water flows. Cyclone filters used for water treatment can be used for the purification of both artificial and natural water bodies.

[0003] The existing cyclone filter is provided with a filter screen, through which the sand, dirt and other substances in the rainwater are filtered.

[0025] 4. In the present invention, through the double filtration of the coarse filter and the fine filter, large particles of impurities, suspended matter and some soluble pollutants in rainwater can be effectively removed. The coarse filter first intercepts larger particles, such as mud, leaves, etc., while the fine filter further filters out smaller impurities and pollutants, thereby significantly improving the water purification effect.

[0039] See also Figure 1-Figure 10 The present application provides a cyclone filter for collecting rainwater in a sponge city, comprising a support base 1, on which a filter cartridge 2 is fixedly mounted, and further comprising: a decontamination component, arranged on the filter cartridge 2, for cleaning a fine filter screen 4 and a coarse filter screen 5 inside the filter cartridge 2; a blocking component, arranged on the decontamination component, for simultaneously blocking the inlet of the filter cartridge 2 when the inside of the filter cartridge 2 is blocked; an automatic sewage discharge component, arranged inside the filter cartridge 2, for automatically cleaning impurities such as mud and sand accumulated inside the filter cartridge 2; a stirring component, arranged above the sewage discharge component, for increasing the centrifugal force of rainwater inside the filter cartridge 2;

[0040] The filter cartridge 2 is provided with an inlet pipe 6 and an outlet pipe 7, the bottom of the inlet pipe 6 and the top of the outlet pipe 7 are respectively connected with a second connecting pipe 9 and a first connecting pipe 8, the decontamination assembly includes a first rubber plug 10 slidably and fittedly installed inside the first connecting pipe 8 and a second rubber plug 11 slidably and fittedly installed inside the second connecting pipe 9, and a first connecting plate 14 is slidably installed on the first connecting pipe 8, a first spring 12 is arranged between the first rubber plug 10 and the first connecting plate 14, a second connecting plate 15 in an L-shaped shape is slidably installed on the second connecting pipe 9, a second spring 13 is arranged between the second connecting plate 15 and the second rubber plug 11, and a first connecting plate 14 is slidably installed on the first connecting pipe 8. A resistor plate 16 is installed at the end, a resistor block 17 is fixedly installed at one end of the second connecting plate 15 away from the second spring 13, the resistor block 17 is arranged on the resistor plate 16 and is used in conjunction with the resistor plate 16, a fine filter 4 and a coarse filter 5 are installed inside the filter cartridge 2, and the radius of the filter hole of the fine filter 4 is smaller than the radius of the filter hole on the coarse filter 5, the fine filter 4 is located above the second carbon ring 28, the coarse filter 5 is located above the fine filter 4, the output end of the water inlet pipe 6 is installed inside the filter cartridge 2 and located on the outside of the coarse filter 5, the output end of the water outlet pipe 7 is installed inside the fine filter 4, and the first cleaning brush 23 is located between the filter cartridge 2 and the coarse filter 5, and the second cleaning brush 34 is attached to the cloth Placed on the inner wall of the fine filter 4, rainwater is transported from the water inlet pipe 6 to the filter cartridge 2, and the rainwater first enters the coarse filter 4 for filtration. The mud or other larger substances in the rainwater are filtered through the coarse filter 5 and intercepted by the coarse filter 5 between the filter cartridge 2 and the coarse filter 5. The lighter substances pass through the coarse filter 5 and flow downward through the first carbon ring 3, and then some lighter impurities in the rainwater are filtered through the fine filter 4. After two layers of filtration, the clean rainwater is finally discharged from the outlet pipe 7. Specifically, when the water inlet pipe 6 and the outlet pipe 7 are normally inlet and outlet, due to the large amount of water, the first rubber plug 10 and the second rubber plug 11 in the first connecting pipe 8 and the second connecting pipe 9 are subjected to thrust The first rubber stopper 10 and the second rubber stopper 11 respectively drive the first connecting plate 14 and the second connecting plate 15 to move normally, and the first spring 12 and the second spring 13 are in an extruded state. When the fine filter 4 is blocked and the water output of the water outlet pipe 7 is reduced, the resistance of the first rubber stopper 10 is reduced, and the first spring 12 drives the first rubber stopper 10 to move. The first rubber stopper 10 drives the resistor plate 16 to slide at the bottom of the resistor block 17 through the first connecting plate 14. At this time, the first electromagnet 26 and the second electromagnet 40 receive the signal and operate, so that the second cleaning brush 34 and the first cleaning brush 23 clean the filter holes of the coarse filter 4 and the fine filter 5 respectively.When the water volume of the water inlet 6 decreases, the resistance of the second rubber plug 11 decreases, the second spring 13 drives the second rubber plug 11 to move, and the resistance block 17 slides on the top of the resistance plate 16.

Specifically, when the resistor plate 16 and the resistor block 17 move relative to each other, the resistance will change, and then the signal will be transmitted. It is an existing technology and is only used for it. The first electromagnet 26 is located at the bottom of the rotating plate 19, and the outer wall diameter of the second electromagnet 40 is the same as the inner wall diameter of the positioning cylinder 27. The first carbon block 22 and the second carbon block 30 are both provided with two , and the two first carbon blocks 22 and the two second carbon blocks 30 are connected by electrodes. After the first electromagnet 26 and the second electromagnet 40 receive the signal, the first electromagnet 26 is energized through the settings of the first carbon ring 3 and the first carbon block 22, and the second electromagnet 40 is energized through the settings of the second carbon ring 28 and the second carbon block 30. It should be noted that the rotating plate 19 and the positioning cylinder 27 are both made of iron. At this time, the first electromagnet 26 and the second electromagnet 40 respectively drive the first sleeve 25 and the second sleeve 39 to move upward in a straight line through the magnetic attraction, so that the first electromagnet 26 is magnetically attracted to the bottom of the rotating plate 19, and the second electromagnet 40 is magnetically attracted to the positioning cylinder 27, since the first sleeve 25 is located outside the first cleaning brush 23, and the second sleeve 39 is located inside the mounting rod 38, when the motor 24 drives the rotating plate 19 and the stirring plate 20 to rotate, the first cleaning brush 23 revolves around the outside of the coarse filter 5, so that the brush surface of the first cleaning brush 23 cleans the filter holes of the group filter 5, and when the stirring plate 20 rotates, the second sleeve 39 fixed in the positioning cylinder 27 rotates. At this time, the mounting rod 38 drives the second cleaning brush 34 installed on one side of the connecting frame 33 to revolve inside the fine filter 4, so that the brush surface of the second cleaning brush 34 cleans the filter holes of the fine filter 4, thereby improving the filtering effect.

[0042] Embodiment 2:

[0043] On the basis of the above embodiments, the blocking component includes a mounting frame 44 detachably mounted on the second connecting plate 15, and the mounting frame 44 is provided with teeth 46, and the teeth 46 are meshed with a transmission gear 47, and a rotating shaft 45 is fixedly mounted on the transmission gear 47, and a baffle 43 for blocking the water inlet pipe 6 is fixedly mounted on the end of the rotating shaft 45 away from the transmission gear 47, and the rotating shaft 45 and the water inlet pipe 6 are sealed and rotatably mounted. Specifically, when 4 and 5 inside 2 are blocked, 17 will slide relative to 16, that is, 15 will slide, 15 drives 44 thereon to move, 14 drives 46 thereon to move, and then 47 is driven to rotate through 46, 47 drives 45 to rotate, and 45 drives 43 to rotate inside 6. At this point, when 4 and 5 are blocked, 6 can be sealed to avoid the input of rainwater, so as to prevent impurities such as mud and sand carried by rainwater from continuing to enter the interior of 2 and aggravate the problem of filter blockage.

[0044] Embodiment three:

[0045] On the basis of the above embodiments, a cartridge cover 18 is provided above the filter cartridge 2;

[0046] The stirring assembly includes a motor 24 detachably mounted on the barrel cover 18, the output end of the motor 24 penetrates and extends to the bottom of the barrel cover 18, and a rotating plate 19 is installed thereon, and the bottom end of the rotating plate 19 penetrates and extends to the bottom of the first carbon ring 3, a positioning barrel 27 is installed at the bottom end of the rotating plate 19, and a stirring plate 20 is fixedly installed at the bottom end of the rotating plate 19, the stirring plate 20 is located above the first carbon ring 3 and inside the coarse filter screen 5, and a groove 21 for engaging the coarse filter screen 5 is provided on the barrel cover 18. When rainwater is transported to the filter barrel 2, the motor 24 is started at the same time, and the output end of the motor 24 drives the rotating plate 19 to rotate. At this time, the rotating plate 19 drives the stirring plate 20 to stir the rainwater in the filter barrel 2, so that the rainwater in the filter barrel 2 is in a vortex state, generating centrifugal force, which can improve the filtering effect of rainwater.

Specifically, after the rainwater is filtered, when there are more substances filtered by the fine filter mesh 4 in the fine filter mesh 4, they gradually accumulate and squeeze the air bag 36 upward. Since the pressure sensor 37 is arranged inside the air bag 36, it is a prior art and is only used. When the pressure sensor 37 senses the set pressure value, it sends a signal to the control valve 42. At this time, the control valve 42 opens, and the impurities in the filter cartridge 2 pass through the second carbon ring 28 and are discharged from the sewage pipe 41.
