[0002] With the development of my country's economy and society, the water resource crisis and water environment pollution are becoming increasingly serious. The discharge of various types of sewage and wastewater has increased significantly, seriously endangering the water environment. The control of water pollution has become one of the hot topics in the field of environmental protection at home and abroad. The sewage treatment mode is divided into centralized treatment mode and decentralized treatment mode. Among them, urban sewage adopts centralized treatment mode, and the integrated sewage treatment device adopts flexible, simple and efficient decentralized treatment mode, which is more in line with the characteristics of rural sewage treatment.

[0003] When using existing sewage treatment equipment, since it needs to flush oxygen into the interior of the sewage, it needs to add an air pump as a power source to increase the amount of oxygen flushed into the sewage. In addition, the sewage needs to be filtered during sewage pre-treatment. After long-term use, the filter screen will be clogged. At this time, the filter screen needs to be manually cleaned or replaced, which increases the equipment cost and labor cost of sewage treatment.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0005] In response to the above-mentioned defects, the purpose of the present invention is to provide a non-powered integrated sewage treatment device, which can be equipped with a device for automatically flushing air into the sewage, without the need to flush gas into the sewage through an air pump. At the same time, a device for automatically cleaning the filter is provided, and there is no need for manual replacement or cleaning of the filter, thereby reducing labor costs.

[0009] In one embodiment, a sliding tube is provided at one end of the two control tubes away from the sewage pipe, and the slider is slidably connected to the inside of the sliding tube, and the sliding of the slider controls the position of the cleaning member.

[0010] In one embodiment, the cleaning element comprises:

[0011] a sliding post slidably connected to the interior of the sliding sleeve;

[0012] A scraper is slidably connected to the sewage pipe and closely adheres to the working surface of the filter element.

[0033] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6The present invention provides an unpowered integrated sewage treatment device, which includes a shell 2, a maintenance port 6 and a water outlet 3 on the top and bottom thereof, respectively, to ensure that the interior of the shell 2 can be inspected and maintained through the maintenance port 6, and a water outlet 3 is provided at the same time to ensure that the treated sewage can be discharged from the water outlet 3; a sewage pipe 5 inserted into the shell 2, and a water distribution pan 13 is provided at one end of the sewage pipe 5 located inside the shell 2, and the sewage is injected into the interior of the shell 2 from the water distribution pan 13. By arranging the water distribution pan 13 on the top of the inner side of the sewage shell 2, it is ensured that the sewage can be evenly injected into the interior of the shell 2, which facilitates the mixing of air and sewage, thereby facilitating the full treatment of the sewage. A filter element 11 is provided inside the sewage pipe 5, and the filter element 11 can adopt a structure similar to a filter mesh to ensure that The solid impurities inside the sewage are filtered to ensure the subsequent treatment of the sewage; a control component 16 is arranged on the sewage pipe 5 to clean the filter element 11, and the control component 16 includes a control tube 163 connected to both sides of the filter element 11, and a slider 17 is provided inside the control tube 163. A sliding sleeve 162 is provided between the two control tubes 163, and a cleaning member 12 is provided inside the sliding sleeve 162 for cleaning the filter screen. When the filter screen is blocked, the slider 17 slides and controls the cleaning member 12 to clean the filter screen, and after cleaning is completed, the slider 17 and the cleaning member 12 are reset to the initial position, so that the change in water pressure on both sides of the filter element 11 can be utilized to drive the slider 17 to slide, further scraping off the blocked objects on the filter element 11, and further ensuring the cleaning effect of the filter element 11.

[0034] Among them, in order to ensure the normal distribution process of the water distribution tray 13, the water distribution tray 13 can be set into a disc-shaped structure, and a number of evenly arranged through holes are opened at the bottom of the disc-shaped structure, so as to facilitate the uniform injection of sewage into the interior of the shell 2. The filter element 11 is set inside the sewage pipe 5 to prevent solid impurities from entering the interior of the shell 2. At the same time, the sewage storage device is set at the top of the shell 2 and is injected into the interior of the sewage pipe 5 under the action of gravity, so there is no need to set up a power device such as a water pump to transport the sewage, thereby reducing energy waste.

[0035] In an exemplary embodiment of the present application, a vent pipe 1 is inserted into the bottom of the shell 2, and the vent pipe 1 is arranged in an L shape. The top of the vent pipe 1 is higher than the top of the shell 2, and the higher the top of the vent pipe 1 is, the better. In this way, the external air can enter the interior of the vent pipe 1 through the air inlet 4 through the principle of a chimney. The part of the sewage pipe 5 located inside the shell 2 is provided with a contraction section 8. The contraction section 8 is a short and thin throat structure. This is the position where the fluid flow rate is fastest and the pressure is reduced the most. Then, a connecting pipe 10 is provided between the contraction section 8 and the vent pipe 1. Under the action of the higher flow rate here, At this time, the pressure in the contraction section 8 is very small, and the gas from the inside of the vent pipe 1 is directly sucked into the inside of the contraction section 8, where the sewage and air are fully mixed, thereby ensuring the gas supply effect of the sewage. The connecting pipe 10 is connected to the inside of the contraction section 8. The connecting pipe 10 is a spiral tube. The top surfaces of the spiral tube and the vent pipe 1 are both provided with gas injection ports 7 to ensure that the gas inside the vent pipe 1 can be evenly passed into the interior of the shell 2 to ensure the supply effect of gas to the sewage temporal part. A capillary tube 9 is provided between the spiral tube and the contraction section 8 to ensure that the gas entering the contraction section 8 can be fully mixed with the sewage.

[0036] In addition, in order to ensure the sliding and installation of the slider 17, a sliding tube is provided across the end of the two control tubes 163 away from the sewage pipe 5, and the slider 17 is slidably connected to the inside of the sliding tube. The slider 17 slides to control the position of the cleaning element 12, thereby ensuring that the filter element 11 can be cleaned by the sliding of the slider 17.

[0037] At the same time, in order to ensure the normal cleaning effect of the cleaning member 12, Figure 6 and Figure 7 , the cleaning member 12 includes:

[0038] The sliding post 123 is slidably connected to the interior of the sliding sleeve 162, so that the cleaning element 12 can be controlled to clean the filter element 11 by controlling the position of the sliding post 123;

[0039] The scraper 122 is slidably connected to the sewage pipe 5 and is in close contact with the working surface of the filter element 11. By being in close contact, it ensures that impurities adhering to the filter element 11 can be cleaned. An impurity channel 15 is provided on the side of the sewage pipe 5 away from the control component 16. The movement of the scraper 122 pushes the impurities on the filter element 11 into the interior of the impurity channel 15, thereby directly discharging the impurities scraped by the scraper 122 from the impurity channel 15 out of the shell 2.

[0040] Furthermore, in order to ensure the normal sliding and driving effect of the slider 17, a limiting portion 19 is provided inside the sliding tube, and a magnetic disk 20 with a through hole in the middle is provided at one end of the sliding tube away from the limiting portion 19. The slider 17 is slidably connected between the limiting portion 19 and the magnetic disk 20. At the same time, the sliding sleeve 162 is arranged between the limiting portion 19 and the magnetic disk 20 to ensure that the pressure of the hydraulic fluid inside the sliding sleeve 162 can be adjusted while the slider 17 slides, thereby driving the sliding column 123 to slide inside the sliding sleeve 162, and further driving the scraper 122 to slide to clean the filter element 11. The sliding structures inside the structure adopt various structures that can seal the liquid to ensure the sealing effect and pressure driving effect. In order to ensure the driving and control of the slider 17, the parameters of the return spring 18 can be adaptively selected to ensure that it meets the needs of the device.

[0041] Better, combined Figures 1 to 8In order to ensure that both ends of the slider 17 can directly contact the liquid on both sides of the filter element 11, the slider 17 includes a sealing disk 171 slidably connected between the limit portion 19 and the magnetic disk 20, a guide rod 172 passing through the limit portion 19, and a force disk 173 provided at the end of the guide rod 172 away from the sealing disk 171. The force disk 173 contacts the liquid on the water outlet side of the filter element 11, and the sealing disk 171 contacts the sewage on the water inlet side of the filter element 11, thereby ensuring that when the filter element 11 is blocked, the liquid pressure on both sides of the filter element 11 changes, thereby pushing the slider 1 7 slides inside the sliding tube, thereby pushing the movement of the cleaning member 12. In order to ensure the reset of the cleaning member 12, a reset spring 18 is provided between the limiting portion 19 and the sealing disk 171. The sealing disk 171 is magnetically adsorbed with the magnetic disk 20. The sliding sleeve 162 is provided between the magnetic disk 20 and the limiting portion 19. The sealing disk 171 contacts the liquid on the water inlet side of the filter element 11, and the force disk 173 contacts the liquid on the water outlet side of the filter element 11. The space between the magnetic disk 20 and the limiting portion 19 is filled with hydraulic fluid to ensure that when in use, the filter element 11 is not blocked. At this time, the liquid pressure at both ends of the filter element 11 is not much different. The slider 17 is affected by the magnetic disk 20, and the sealing disk 171 is adsorbed on the magnetic disk 20. Then, when the filter element 11 is blocked, the pressure difference between the liquid on the water inlet side of the filter element 11 and the pressure on the water outlet side of the filter element 11 increases, and the thrust on the sealing disk 171 increases. When the thrust is greater than the pressure of the magnetic disk 20 and the return spring 18, the sealing disk 171 is forced to separate from the magnetic disk 20, and then the sealing disk 171 is forced to slide, pressing the hydraulic fluid to flow to the sliding pipe. At this time, the sliding column 123 is forced to slide. The scraper 122 scrapes the impurities on the filter element 11 and pushes the impurities into the interior of the impurity channel 15 and discharges them from the sewage pipe 14 outside the impurity channel 15 to complete the cleaning of the filter element 11. After cleaning, the sewage can flow normally. The water pressure on both sides of the filter element is not much different. Under the action of the reset spring 18, the sealing disk 171 is pushed to be adsorbed on the magnetic disk 20, thereby completing the automatic cleaning and resetting of the filter element 11. The sliding structures inside the structure adopt various structures that can seal the liquid to ensure the sealing effect and pressure driving effect.

[0042] Furthermore, in order to ensure the discharge of sewage and impurities generated during cleaning by the cleaning element 12, the scraper 122 is arranged into an annular structure, and a sealing portion 121 is provided on one side of the scraper 122. When the sealing portion 121 is in contact with the sealing surface 151 of the impurity channel 15, the sewage pipe 5 is sealed, thereby ensuring the sealing of the sewage pipe 5 and the impurity channel 15. The portion of the impurity channel 15 located on the side wall of the sewage pipe 5 is in contact with the side wall of the scraper 122 and sealed to prevent sewage from leaking from the inside of the sewage pipe 5 during use. The side wall of the impurity channel 15 is provided with a flow gap 152. When the scraper 122 scrapes the impurities of the filter element 11, the flow gap 152 is connected to the inside of the sewage pipe 5. The flow gap 152 extends to the outside of the shell 2 and discharges the impurities through the sewage outlet, completing the cleaning of the filter element 11.

[0043] During cleaning, the sliding column 123 slides inside the sliding sleeve 162 under the action of hydraulic thrust, pushing the scraper 122 to move and clean the impurities on the working surface of the filter screen. After the blocking portion 121 at the front end of the scraper 122 is separated from the sealing surface 151, the blocking portion 121 enters the flow gap 152. The front end of the annular scraper 122 is connected to the flow gap 152. At the same time, the scraper 122 continues to clean the filter screen and discharges the generated impurities into the interior of the impurity channel 15 through the flow gap 152 under the action of the flow of sewage (see Figure 9 , the arrows indicate the flow direction of impurities and sewage), the impurities are discharged, and after cleaning, the sewage continues to flow through the filter. When the pressure difference at both ends of the slider 17 is reduced to a certain value, the slider 17 is reset to the initial position under the action of the reset spring 18, and the sliding column 123 is forced to retract to the initial position, completing the automatic cleaning of the filter.

[0044] Of course, the present invention may have many other embodiments.
