[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] This specific embodiment is a wastewater filtration and purification device, the structural schematic diagram of which is shown below. Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the system includes a mounting frame 1, a housing 8 mounted on the upper surface of the mounting frame 1, a filter plate 9 installed inside the housing 8, a cleaning assembly 2 mounted on the side of the housing 8, a limiting rod 16 mounted at the middle of one end of the upper surface of the housing 8, the limiting rod 16 movably engaging a hanging plate 13, the hanging plate 13 being L-shaped, a collection box 14 connected to the lower end of the hanging plate 13, the collection box 14 being flush with the filter plate 9, a support plate 10 mounted at the middle of the upper part of the housing 8 away from the limiting rod 16, the support plate 10 having a water inlet pipe 11 passing through it, the filter plate 9 having multiple sets of evenly distributed first filter holes 12, the collection box 14 having multiple sets of evenly distributed second filter holes 15 at the lower part, the diameter of the second filter holes 15 being smaller than the first filter holes 12, a box 3 mounted on the upper surface of the mounting frame 1, the box 3 being lower than the housing 8, a box cover 6 movably mounted on the box 3, and a filter screen 5 movably mounted on the box 3 and the box cover 6. A discharge pipe 4 is installed through the lower side of the body 3, and a connecting pipe 7 is installed through the upper surface of the body 3. The other end of the connecting pipe 7 is connected through the lower side of the box 8. In actual sewage treatment, sewage is introduced into the system through the inlet pipe 11. After the sewage enters the box 8, it comes into direct contact with the filter plate 9. Under the action of the first filter hole 12, large impurities are filtered. Then the sewage falls into the bottom of the box 8 and enters the box 3 through the connecting pipe 7. Under the action of the filter screen 5, the sewage is filtered and purified. Then the sewage is discharged through the discharge pipe 4. The cleaning component 2 is started by timed activation (the motor 203 is started by timed activation of the PLC controller) to clean the upper surface of the filter plate 9. Large impurities are pushed into the collection box 14. Then the collection box 14 is taken out by timed activation (the second filter hole 15 at the bottom of the collection box 14 is smaller than the first filter hole 12 to prevent impurities from falling).
[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the cleaning component 2 includes a side block 201, which is fixedly installed on the side of the housing 8. A groove 202 is formed inside the side block 201. A motor 203 is mounted on the side of the side block 201, and a screw 204 is connected to the motor 203. A movable plate 205 is threaded through the screw 204. A scraper 206 is mounted on the other end of the movable plate 205. The scraper 206 is inclined and contacts the upper surface of the filter plate 9. The movable plate 205 slides and adapts to the groove 202. When the motor 203 starts, it drives the screw 204 to rotate. The rotation of the screw 204 drives the movable plate 205 to move along the groove 202. The movement of the movable plate 205 drives the scraper 206 (made of rubber) to move. The movement of the scraper 206 scrapes large impurities into the collection box 14. Then, the motor 203 reverses, driving the scraper 206 back to its initial position (e.g., ...). Figure 1 As shown, the initial position is close to the support plate 10.
[0031] Working Principle: During actual wastewater treatment, wastewater is introduced into the system through the inlet pipe 11. After entering the tank 8, the wastewater comes into direct contact with the filter plate 9. Under the action of the first filter hole 12, large impurities are filtered out. Subsequently, the wastewater falls into the bottom of the tank 8 and then into the box 3 through the connecting pipe 7. Under the action of the filter screen 5, the wastewater is filtered and purified. Then, the wastewater is discharged through the discharge pipe 4. The cleaning component 2 is started on a timer (the motor 203 is started on a timer controlled by the PLC controller) to clean the upper surface of the filter plate 9. Large impurities are pushed into the collection box 1. 4. Then, the collection box 14 is taken out periodically (the second filter hole 15 at the bottom of the collection box 14 is smaller than the first filter hole 12 to prevent impurities from falling). The filter plate 9 and the first filter hole 12 facilitate the initial filtration of sewage and the interception of large impurities, thus extending the service life of the filter screen 5. The collection box 14 facilitates the collection of large impurities for unified treatment. The limit rod 16 and the hanging plate 13 facilitate the fixing of the collection box 14. The movable locking limit rod 16 and the hanging plate 13 also facilitate the removal of the collection box 14.
[0032] The cleaning component 2 operates as follows: Motor 203 starts, driving screw 204 to rotate. Screw 204's rotation causes moving plate 205 to move along slide 202. Moving plate 205 causes scraper 206 (made of rubber) to move. Scraper 206 scrapes large impurities into collection box 14. Then, motor 203 reverses, driving scraper 206 back to its initial position (e.g., ...). Figure 1 As shown, the initial position is close to the support plate 10. Through the setting of the cleaning component 2, the filter plate 9 is automatically cleaned, which can effectively prevent the filter plate 9 from clogging frequently, ensure the normal operation of filtration and purification, and improve practicality. At the same time, the rubber scraper 206 can avoid scratching the filter plate 9 and ensure the normal use of the filter plate 9.
[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
