Description

Technical Field

[0001] This invention relates to the field of wastewater purification and treatment technology, and in particular to a wastewater purification and treatment device with a self-flushing structure. Background Technology

[0002] With the acceleration of industrialization and the improvement of urbanization, water scarcity and water pollution have become increasingly prominent problems. Statistics show that approximately 42% of domestic sewage worldwide is still discharged directly without adequate treatment, carrying pollutants that seriously threaten the safety of drinking water sources and aquatic ecosystems. The requirements for the quality of sewage treatment effluent are constantly increasing, especially the emission standards for key indicators such as suspended solids and chemical oxygen demand (COD) are becoming increasingly stringent. At the same time, fields such as industrial circulating cooling water, oilfield reinjection water, advanced municipal sewage treatment, and agricultural irrigation are placing higher demands on the treatment efficiency, operational stability, and economic efficiency of water purification equipment. Filtration and separation are one of the core technological units in the water treatment process.

[0003] Chinese patent CN109806643B discloses a wastewater treatment device with separate cleaning. A third inlet pipe is installed on the left side of the upper end face of the filter box, and a second inlet pipe is installed on the right side. A first inlet pipe and a right drain pipe are installed from top to bottom on the right end face of the filter box. A left drain pipe is installed on the left end face of the filter box. The left filter screen is fixed upwards and tilted from left to right on the left side of the filter tank, with the upper edge of the left end of the left filter screen flush with the lower edge of the left drain pipe. The right filter screen is hinged to the right end of the left filter screen. A sleeve block is hinged to the right end of the right filter screen. The sleeve block is fitted onto a vertical drive block in a left-right direction. The vertical drive block is raised and lowered on the right side wall of the filter tank. A vertically upward through-hole is formed in the center of the upper side wall of the filter tank. A partition plate is raised and lowered within the lifting insertion hole. Several evenly distributed flushing nozzles are formed on the left and right end faces of the partition plate. In this invention, the left and right filter screens are separated and flushed, and the filtration process does not need to be stopped during the flushing process. The device uses a nozzle to rinse the filter screen, but the nozzle is located on the left side of the partition plate. The water flow is from the top of the filter screen downwards and towards the drain pipe on the left. This rinsing direction is basically the same as the water flow direction during filtration (from the upper right to the lower left through the filter screen). For particles stuck in the filter screen pores, the effect of rinsing in the same direction is usually not as good as rinsing in the opposite direction. In addition, the nozzle angle is fixed, which can easily create dead corners for cleaning, resulting in low cleaning efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides: a wastewater purification and treatment device with a self-flushing structure, comprising: The processing cylinder has a circular cylindrical structure and a slag removal port opened on the outside of the processing cylinder.

The rotating filter screen can be used for zoned filtration, which effectively improves the filtration efficiency of the filter screen. The rinsing device includes: An adsorption tube has an arc-shaped tubular structure and a water pumping pipe at one end of the adsorption tube.

The water pump 92 is connected to the inside of the treatment cylinder 1 and to the adsorption pipe 91. The outer side of the circulation pump 94 is fixedly connected to the outer wall of the treatment cylinder 1 through a bracket. The connecting pipe 96 is connected to the water supply pipe 95.

The bottom of the reinforcing frame 97 is fixedly connected to the bottom of the inner wall of the treatment cylinder 1.

[0024] The bottom of the inlet pipe 910 is connected to the top of the water supply pipe 95. The outlet pipe 913 passes through the outer shell 912 and is fixedly connected to the outer shell 912. There are two sets of outlet pipes 913, which are symmetrically distributed on both sides of the outer shell 912. There are multiple sets of high-pressure nozzles 915, which are evenly distributed on the spray pipe 914. The inner wall of the outer shell 912 is slidably connected to the outer wall of the inner shell 98.

[0025] Both ends of the limiting post 991 are fixedly connected to the outer wall of the outer shell 912 through brackets. There are two sets of limiting posts 991, and the two sets of limiting posts 991 are symmetrically distributed on both sides of the outer shell 912.

[0026] One side of the positioning frame 994 is fixedly connected to the outer wall of the inner shell 98, and one side of the driven gear 998 is fixedly connected to one end of the rotating column 993 through the connecting shaft.

[0027] The drainage device 8 includes a sewage inlet pipe 81, one end of which is connected to a sewage delivery pipe 82. The bottom of the sewage delivery pipe 82 is connected to a fixed pipe 83. The bottom of the fixed pipe 83 is connected to an arc-shaped drainage frame 84. Both sides of the arc-shaped drainage frame 84 are fixedly connected to L-shaped plates 85. One side of the L-shaped plate 85 is fixedly connected to a tension spring 86. The end of the tension spring 86 away from the L-shaped plate 85 is fixedly connected to a limit frame 87. Both ends of the limit frame 87 are fixedly connected to brush rollers 88 via brackets.

[0028] The outer side of the inlet pipe 81 is fixedly connected to the top of the annular plate 4 via a bracket. The fixing pipe 83 passes through the top of the annular plate 4 and is fixedly connected to the annular plate 4. Brush heads with bristles are evenly installed on the outer side of the brush roller 88.

[0029] In use, wastewater enters the sewage delivery pipe 82 through the sewage inlet pipe 81, and then flows into the fixed pipe 83 through the sewage delivery pipe 82. The wastewater entering the fixed pipe 83 is finally discharged through the arc-shaped drainage frame 84. Since the bottom of the arc-shaped drainage frame 84 is close to the top of the filter screen 5, the wastewater discharged from the arc-shaped drainage frame 84 directly contacts the filter screen 5, allowing the filter screen 5 to filter the wastewater and remove impurities. After solid-liquid separation filtration, the water passes through the filter holes of the filter screen 5. The drive motor 7 is turned on, and the output end of the drive motor 7 drives the rotating shaft 6 to rotate, which in turn drives the filter screen 5 to rotate. The filter screen 5 and the annular plate 4 rotate. When the filter screen 5 rotates, the unfiltered area is rotated to the area below the arc-shaped drainage frame 84. The rotating filter screen 5 can be used for zoned filtration, which effectively improves the filtration efficiency of the filter screen 5. When the filter screen 5 rotates, it passes the brush roller 88. At this time, the brush roller 88 can clean the filtered area, brushing away impurities that are easy to entangle and adhere to the surface of the filter screen, improving the cleaning effect of sticky dirt. In addition, the clamping spring 86 always presses the brush roller 88 tightly on the filter screen 5, and the brush roller 88 always adheres to the surface of the filter screen 5, so that every angle of the filter screen can be effectively brushed.

[0030] The circulating pump 94 is turned on to draw water from the treatment cylinder 1, which has been treated by the filter screen 5, out through the pumping pipe 92. The water in the pumping pipe 92 enters the adsorption pipe 91. Since the adsorption pipe 91 is equipped with an adsorption component, the adsorption component can perform fine adsorption and filtration treatment on the incoming water. The treated water is then pumped by the circulating pump 94 into the connecting pipe 96, the water supply pipe 95, the inlet pipe 910, and the inner shell 98 in sequence. It then enters the spray pipe 914 through the outlet pipe 913 and is finally sprayed onto the filter screen 5 through the high-pressure nozzle 915. The high-pressure water flow backwashes the filter screen 5, directly removing the deep blockages inside the filter pores of the filter screen 5. Combined with the cleaning of the brush roller, the cleaning efficiency of the filter screen 5 is further improved. Moreover, the rinsing water is the filtered water inside the equipment, and there is no need to use external clean water.

[0031] When the rotary motor 996 is turned on, its output drives the drive gear 997 to rotate. The drive gear 997 then drives the meshing driven gear 998 to rotate. Both sets of driven gears 998 rotate in the same direction, simultaneously driving the rotating column 993 to rotate. When one set of driven gears 998 drives the rotating column 993 to rotate, it tightens the traction belt 992 wrapped around the outside of the rotating column 993. When the other set of driven gears 998 drives the rotating column 993 to rotate, it releases the traction belt 992 on the outside of the rotating column 993. The rotation direction of the two sets of driven gears 998 can be controlled by the forward and reverse rotation of the rotary motor 996. The traction belt 992 pulls the limiting post 991, thereby pulling the outer shell 912, causing the outer shell 912 to move along the outer wall of the inner shell 98. The angle of the spray pipe 914 can be adjusted through the water outlet pipe 913, and the angle of the high-pressure nozzle 915 can be adjusted to improve the rinsing range and efficiency.

[0032] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
