DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0021] Reference Figures 1 to 4 A wastewater filtration device with a cache structure includes a treatment box 2, a dosing box 19 (the interior of the dosing box 19 is filled with a coagulant, and the coagulant can help to combine suspended solids, turbidity and colloidal substances in the wastewater into larger clusters, thereby promoting their sedimentation or filtration), a buffer rod 10, an electric push rod 23, a collection frame 20 and a stamping plate 24. The above structure can accelerate the speed of wastewater filtration and reduce the impact force when the wastewater flow is severe, while facilitating the collection and treatment of filtered impurities.

Two groups of symmetrical buffer rods 10 are connected, and the top ends of the buffer rods 10 are fixedly connected to the lower surface of the buffer plate 6, the inner walls on both sides of the treatment box 2 are fixedly connected with filter screen plates 11, and the outer wall of the support frame 1 is provided with a dosing box 19. The inner wall of the bottom end of the dosing box 19 is fixedly connected with an infusion tube, and the other end of the infusion tube is fixedly connected to the inner wall of the treatment box 2. When the wastewater flow rate is large, the impact and pressure brought by the wastewater can be reduced, and the inner wall and the treatment box can be gradually released to prevent stamping damage to the filter screen plate 11 and the internal components of the device, thereby avoiding affecting the service life of the filter screen and components, and improving the use effect of the wastewater filtration device.

[0023] The top inner wall of the treatment box 2 is rotatably connected with a rotating rod 12, and the top of the rotating rod 12 is fixedly connected with a brush assembly 21, and the lower surface of the brush assembly 21 is fitted with the upper surface of the filter screen plate 11, and the inner walls on both sides of the treatment box 2 are fixedly connected with baffles 13, and the other end of the rotating rod 12 passes through the inner wall of the baffle 13 and is rotatably connected with the bottom inner wall of the treatment box 2, and the rod walls of the rotating rod 12 are respectively fixed with impellers 14 and driving gears 15, and the bottom inner wall of the treatment box 2 is rotatably connected with two symmetrical stirring rods 16, and the rod walls of the two stirring rods 16 are fixedly connected with blades 17 and driven gears 18, and the driving gear 15 and the two driven gears 18 are meshed with each other, and the impeller and the rotating rod are driven to rotate by the slowed wastewater flow, which can effectively make the filtered wastewater and the medicine fully mixed, and at the same time, the filter screen plate 11 can be cleaned in conjunction with the cleaning component to avoid clogging of the filter screen plate 11 and improve the filtering effect of the wastewater filtering device.

[0024] The operating principle of the utility model is described as follows: when filtering wastewater, the staff first sends the wastewater to be filtered from the inside of the water inlet trough 3 into the inside of the treatment box 2. When the wastewater flow rate is violent, the impact force generated by the wastewater is first buffered by the buffer plate 6, so that it has a downward thrust on the buffer plate 6, and then the buffer plate 6 drives the two buffer rods 10 to move downward, and then the moving plate 8 slides downward inside the mounting block 7, and pressure is applied to the two compression springs 9, so that the two compression springs 9 undergo elastic deformation to perform secondary buffering of the impact force, which can reduce the impact and pressure brought by the wastewater when the wastewater flow rate is large, and gradually release the inner wall and the treatment box, so as to prevent the filter screen and the internal parts of the device from being damaged by stamping, avoid affecting the service life of the filter screen and the parts, and improve the use effect of the wastewater filtering device.

[0025] After buffering, the wastewater flows downward from the through hole in the buffer plate 6 to the filter screen plate 11, and at the same time, the medicine is injected into the medicine adding box 19 to make it flow to the inside of the treatment box 2. The wastewater impacts the impeller 14 under the action of the two fixed blocks 5 to make it rotate, and then the impeller 14 drives the rotating rod 12 to rotate. While rotating, the rotating rod 12 drives the driving gear 15 and the brush assembly 21 to rotate synchronously, so that the driving gear 15 can drive the two driven gears 18 to rotate, so that the stirring rod 16 and the blades 17 can fully mix the wastewater and the medicine. At the same time, the rotating rod 12 drives the brush assembly 21 to clean the filter screen plate 11, which can effectively mix the filtered wastewater with the medicine. At the same time, the cleaning component can be used to clean the filter screen plate 11 to avoid clogging of the filter screen plate 11, thereby improving the filtering effect of the wastewater filtering device. After filtering, the wastewater will be centrally processed by the staff.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
