Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an anti-blocking device for an inlet of a sewage treatment pool. Background Art

[0002] Sewage treatment pools are facilities used to purify urban domestic and industrial sewage. They remove pollutants such as suspended matter, colloidal substances, organic matter and pathogens in sewage through a series of physical, chemical or biological treatment methods. After the sewage is pressurized and transported by an external water pump, it needs to be transported through an inlet pipe to allow the sewage to enter the sewage treatment pool for treatment.

[0003] Although the existing sewage treatment pool inlet pipe has many benefits, it still has the following problems: it lacks a cleaning structure for the inlet pipe entrance, which causes the particles and flocs in the sewage to adhere to the inner wall of the inlet pipe when the sewage flows inside the inlet pipe. If it is not cleaned for a long time, it will cause accumulation and agglomeration, and even cause blockage inside the inlet pipe, affecting the smoothness of the sewage flowing into the sewage treatment pool. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides an anti-clogging device for the inlet of a sewage treatment pool.

[0005] The technical solution adopted by the utility model to solve its technical problems is an anti-blocking device for the entrance of a sewage treatment pool, comprising a water inlet pipe, a support plate and a connecting plate, a fixing frame is installed on one side of the outer wall of the upper end of the water inlet pipe, a fixing plate is installed on the outer wall of the lower end of the fixing frame, support frames are installed on the outer walls of both sides of the fixing plate, a support plate is provided on the outside of the support frame, a rotating shaft is rotatably installed on the outer wall of one side of the support plate, a connecting plate is installed on the outer wall of one end of the rotating shaft, a movable groove is opened inside the connecting plate, and a piston rod is movably installed inside the movable groove.

[0006] By adopting the above technical solution, the fixing frame keeps the position of the fixing plate and the support plate stable. When the sewage inside the water inlet pipe is discharged toward the impeller, the sewage will flow through the impeller, thereby driving the impeller to rotate according to the flow of sewage. The impeller drives the rotating shaft and the connecting plate to rotate in a circle, and the scraper is used to scrape and clean the inner wall of the water inlet pipe.

[0007] Specifically, bolts are provided on the outer walls on both sides of the fixing frame, and the fixing frame is connected to the water inlet pipe through the bolts.

[0008] By adopting the above technical solution, the bolts fix the position of the fixing frame, ensuring the positional stability of the fixing frame and the support plate outside the water inlet pipe.

[0009] Specifically, a vibration rod is installed on the outer wall of one side of the support frame, and the other end of the vibration rod is connected to the outer wall of the support plate.

[0010] By adopting the above technical solution, the vibration rod ensures the vibration position stability of the support plate located outside the support frame, thereby maintaining the relative position stability of the rotating shaft.

[0011] Specifically, vibration motors are installed on both sides of the outer wall of the upper end of the support plate, and the vibration motors do not contact the support frame.

[0012] By adopting the above technical solution, the vibration motor drives the support plate to vibrate at high frequency, thereby removing dirt adhered to the impeller surface, maintaining the cleanliness of the impeller outer surface, and ensuring the stable rotation speed of the impeller.

[0013] Specifically, an impeller is installed on one side of the outer wall of the rotating shaft, and the impeller is located outside the water inlet pipe.

[0014] By adopting the above technical solution, the sewage discharged from the water inlet pipe impacts the surface of the impeller. According to the curved shape of the impeller surface, the flowing sewage drives the impeller to rotate in a circular motion.

[0015] Specifically, a spring is provided on one side of the inner wall of the movable groove, and the piston rod is elastically connected to the inner wall of the movable groove through the spring.

[0016] By adopting the above technical solution, the spring force pushes the piston rod, maintaining the relative position stability of the piston rod inside the movable groove, and ensuring that the distance between the scraper and the connecting plate can be adjusted, maintaining stable contact between the scraper and the inner wall of the water inlet pipe.

[0017] Specifically, the piston rod passes through the outer wall of one end of the movable groove and is installed with a scraper. The size of the scraper is adapted to the size of the inner wall of the water inlet pipe, and the scraper is in contact with the inner wall of the water inlet pipe.

[0018] By adopting the above technical solution, the rotating shaft is driven to rotate by the impeller, thereby driving the connecting plate, piston rod and scraper to rotate in a circular motion. The scraper rotates on the inner wall of the water inlet pipe and scrapes and cleans the particles and flocs attached to the inner wall of the water inlet pipe. The fallen dirt follows the flow of sewage and flows into the sewage treatment tank, thereby maintaining the relative cleanliness of the inner wall of the water inlet pipe and preventing the accumulation of dirt.

[0019] Beneficial effects of the utility model:

[0020] (1) The utility model discloses an anti-blocking device for the inlet of a sewage treatment pool. When the sewage inside the water inlet pipe is discharged toward the impeller, the sewage will flow through the impeller, thereby driving the impeller to rotate according to the flow of the sewage. The impeller drives the scraper to scrape and clean the inner wall of the water inlet pipe, preventing particles and flocs in the sewage from adhering to the inner wall of the water inlet pipe, maintaining the relative cleanliness of the inner wall of the water inlet pipe, preventing impurities from gathering and agglomerating, ensuring the diameter of the inner wall of the water inlet pipe, and ensuring the smoothness of the flow of sewage through the water inlet pipe.

[0021] (2) The utility model discloses an anti-blocking device for the inlet of a sewage treatment pool. The vibration motor drives the support plate to vibrate at high frequency. The vibration drives the dirt attached to the surface of the impeller to fall off, thereby preventing the dirt from adhering to the surface of the impeller, maintaining the relative cleanliness of the impeller surface, preventing the weight of the impeller from being affected by the dirt, ensuring the smoothness of the impeller's rotation, thereby ensuring the rotation speed of the scraper and ensuring the cleaning effect of the scraper on the inner wall of the water inlet pipe.

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] In order to save manpower and improve efficiency, as an embodiment of the present invention, Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the utility model is an anti-blocking device for the entrance of a sewage treatment pool, comprising an inlet pipe 1, a support plate 2 and a connecting plate 3. A fixing frame 11 is installed on one side of the outer wall of the upper end of the water inlet pipe 1, a fixing plate 12 is installed on the outer wall of the lower end of the fixing frame 11, support frames 13 are installed on the outer walls on both sides of the fixing plate 12, a support plate 2 is arranged on the outside of the support frame 13, a rotating shaft 22 is rotatably installed on the outer wall of one side of the support plate 2, a connecting plate 3 is installed on the outer wall of one end of the rotating shaft 22, a movable groove 31 is opened inside the connecting plate 3, and a piston rod 32 is movably installed inside the movable groove 31.

[0030] During use, the fixing frame 11 keeps the fixed plate 12 and the support plate 2 in a stable position. When the sewage inside the water inlet pipe 1 is discharged toward the impeller 23, the sewage will flow through the impeller 23, thereby driving the impeller 23 to rotate according to the flow of sewage. The impeller 23 drives the rotating shaft 22 and the connecting plate 3 to rotate in a circle, and the scraper 33 is used to scrape and clean the inner wall of the water inlet pipe 1.

[0031] In order to keep the support plate 2 in a stable position, for example, Figure 1 As shown, bolts are provided on both sides of the outer walls of the fixing frame 11, and the fixing frame 11 is connected to the water inlet pipe 1 through the bolts.

[0032] When in use, the bolts fix the position of the fixing frame 11 to ensure the positional stability of the fixing frame 11 and the support plate 2 outside the water inlet pipe 1 .

[0033] In order to maintain the vibration position of the support plate 2 stable, illustratively, as shown in the figure, a vibration rod 14 is installed on the outer wall of one side of the support frame 13, and the other end of the vibration rod 14 is connected to the outer wall of the support plate 2.

[0034] When in use, the vibration rod 14 ensures the vibration position stability of the support plate 2 located outside the support frame 13, thereby maintaining the relative position stability of the rotating shaft 22.

[0035] To clean the impeller 23, for example, Figure 2 As shown, vibration motors 21 are installed on both sides of the outer wall of the upper end of the support plate 2, and the vibration motors 21 do not contact the support frame 13.

[0036] When in use, the vibration motor 21 drives the support plate 2 to vibrate at high frequency, thereby removing dirt adhered to the surface of the impeller 23 , maintaining the cleanliness of the outer surface of the impeller 23 , and ensuring that the rotation speed of the impeller 23 is stable.

[0037] In order to drive the rotating shaft 22 without power, illustratively, as shown in the figure, an impeller 23 is installed on one side of the outer wall of the rotating shaft 22, and the impeller 23 is located outside the water inlet pipe 1.

[0038] During use, sewage discharged from the water inlet pipe 1 impacts the surface of the impeller 23 . Due to the curved shape of the surface of the impeller 23 , the flowing sewage drives the impeller 23 to rotate in a circular motion.

[0039] In order to maintain the position of the scraper 33, for example, Figure 4 As shown, a spring 34 is provided on one side of the inner wall of the movable groove 31 , and the piston rod 32 is elastically connected to the inner wall of the movable groove 31 through the spring 34 .

[0040] When in use, the spring 34 pushes the piston rod 32, maintaining the relative position stability of the piston rod 32 inside the movable groove 31, and ensuring that the distance between the scraper 33 and the connecting plate 3 can be adjusted, maintaining the stable contact between the scraper 33 and the inner wall of the water inlet pipe 1.

[0041] To clean up the dirt, for example, Figure 4 As shown, the piston rod 32 passes through the outer wall of one end of the movable groove 31 and a scraper 33 is installed. The size of the scraper 33 is adapted to the size of the inner wall of the water inlet pipe 1, and the scraper 33 contacts the inner wall of the water inlet pipe 1.

[0042] During use, the rotating shaft 22 is driven to rotate by the impeller 23, thereby driving the connecting plate 3, the piston rod 32 and the scraper 33 to rotate in a circular motion. The scraper 33 rotates on the inner wall of the water inlet pipe 1 and scrapes and cleans the particles and flocs attached to the inner wall of the water inlet pipe 1. The fallen dirt follows the flow of sewage and flows into the sewage treatment tank, thereby maintaining the relative cleanliness of the inner wall of the water inlet pipe 1 and preventing the dirt from agglomerating.

[0043] When the utility model is in use, the staff places the scraper 33 inside the water inlet pipe 1, and the spring 34 pushes the piston rod 32, forcing the scraper 33 to contact the inner wall of the water inlet pipe 1. The staff manually takes a wrench to turn the bolt to fix the fixing frame 11 to the outside of the water inlet pipe 1;

[0044] When the sewage inside the water inlet pipe 1 is discharged toward the impeller 23, the sewage will flow through the impeller 23, thereby driving the impeller 23 to rotate according to the flow of sewage. The impeller 23 drives the rotating shaft 22 and the connecting plate 3 to rotate in a circle, and the scraper 33 is used to scrape and clean the inner wall of the water inlet pipe 1.

[0045] The vibration motor 21 drives the support plate 2 to vibrate at a high frequency, causing the support plate 2 to vibrate through the vibration rod 14, while the scraper 33 is kept relatively stable by the piston rod 32 and the spring 34, thereby preventing the scraper 33 from being damaged by the vibration and causing damage to the inner wall of the water inlet pipe 1;

[0046] The vibration generated by the vibration motor 21 drives the dirt attached to the surface of the impeller 23 to fall off, thereby preventing the dirt from adhering to the surface of the impeller 23 and keeping the surface of the impeller 23 relatively clean.
