Technical Field

[0001] The utility model relates to the technical field of mechanical grilles, in particular to an anti-blocking mechanical grille for sewage treatment. Background Art

[0002] A mechanical screen is a screen device that automatically removes debris attached to the screen. One of the earliest purification devices in water supply and drainage treatment technology, the mechanical screen significantly reduces worker labor intensity, protects worker health, reduces head loss in incoming water, and improves pump station efficiency.

[0003] The traditional mechanical screen, after carrying the garbage, rotates the screen so that the garbage on the screen can enter the pipe, and then the pipe enters the collection bin. However, if there is too much garbage accumulated in the pipe, it is easy to cause blockage. At this time, the blocked pipe needs to be cleared manually. Therefore, we propose an anti-blocking mechanical screen for sewage treatment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides an anti-blocking mechanical grille for sewage treatment, which has the advantages of preventing blockage and good fixation, and solves the problems raised by the above-mentioned background technology.

[0006] As a preferred technical solution of the present invention: the bottom of the supporting block 2 is fixedly mounted on the top of the square plate, the controller is electrically connected to the motor, and the motor is fixedly mounted on the top of the fixed plate.

[0007] As an optimal technical solution of the present invention: the self-locking component includes a rectangular plate, a circular shaft is fixedly installed on the outer wall of the rectangular plate, a rotating plate is rotatably connected to the outer wall of the circular shaft, and a pull rod is fixedly installed on the outer wall of the rotating plate.

[0008] As an optimal technical solution of the present invention: the outer wall of the rectangular plate is fixed to the outer wall of the support block 2, the inner wall of the rotating plate is clamped with the limiting rod, and the outer wall of the limiting rod is fixedly installed on the inner wall of one side of the connecting plate close to the self-locking component.

[0009] As an optimal technical solution of the present invention: the scraping assembly includes a motor, a three-hole gear is provided on the top of the motor, a five-hole gear is engaged with the outer wall of the three-hole gear, a fan-shaped tooth plate is fixedly installed on the top of the five-hole gear, the outer wall of the fan-shaped tooth plate is engaged with a rack, and a scraper is fixedly installed on the top of the rack.

[0010] As an optimal technical solution of the present invention: the power output shaft of the motor is connected to the three-hole gear through a circular groove opened on the outer wall of the square plate, the outer wall of the scraper is slidably connected to the inner wall of the pipe through a sliding groove opened at the bottom of the pipe, and there are two groups of five-hole gears and fan-shaped tooth plates respectively, and the rotation directions of the two groups of fan-shaped tooth plates are the same.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The anti-blocking mechanical screen for sewage treatment drives a three-hole gear through the power output shaft of the motor, so that the three-hole gear can drive two groups of five-hole gears to rotate the sector tooth plate. The two groups of sector tooth plates have the same rotation direction. When one group of sector tooth plates is engaged with the rack, the other group of sector tooth plates is not engaged with the rack. At this time, the rack is driven to push forward, so that the rack can drive the scraper to scrape the blocked debris in the inner cavity of the pipe, thereby avoiding the problem that the space in the inner cavity of the pipe is filled due to excessive blockage, and the debris can no longer be stored, and manual discharge of the debris is required.

[0013] 2. The anti-blocking mechanical grille for sewage treatment can rotate on the outer wall of the rectangular plate by pulling the pull rod, so that the pull rod can drive the rotating plate to rotate on the outer wall of the circular shaft. At this time, the rotating plate is pulled out of the outer wall of the rectangular plate, and the limit rod can enter the inner wall of the rectangular plate. When the pull rod is pulled again, the pull rod drives the rotating plate to rotate on the inner wall of the circular shaft. At this time, the rotating plate can clamp the limit rod. At this time, the self-locking assembly can fix the support block one and the support block two to the square plate, thereby ensuring that the square plate is fixed to the scraping assembly, and avoiding the scraping assembly from being separated from the pipeline during operation.

[0026] In the above structure, the bottom of the support block 2 10 is fixed to the top of the square plate 5. When the support block 1 6 and the support block 2 10 are fixed to the pipe 2 through the connecting plate 8, the support block 1 6 and the support block 2 10 can support the square plate 5. The controller 3 is electrically connected to the motor 1101, so that when the scraping component 11 needs to start working, it is only necessary to press the controller 3. At this time, the controller 3 can control the motor 1101, so that the motor 1101 can drive the scraping component 11 to work.

[0027] In a preferred embodiment, the self-locking assembly 9 includes a rectangular plate 901 , a circular shaft 902 is fixedly mounted on the outer wall of the rectangular plate 901 , a rotating plate 903 is rotatably connected to the outer wall of the circular shaft 902 , and a pull rod 904 is fixedly mounted on the outer wall of the rotating plate 903 .

[0028] In a preferred embodiment: the outer wall of the rectangular plate 901 is fixed to the outer wall of the support block 2 10, the inner wall of the rotating plate 903 is clamped with the limit rod, and the outer wall of the limit rod is fixedly installed on the inner wall of the connecting plate 8 close to the self-locking component 9.

[0029] In the above structure, by pulling the pull rod 904, the pull rod 904 can be rotated on the outer wall of the rectangular plate 901, so that the pull rod 904 can drive the rotating plate 903 to rotate on the outer wall of the circular shaft 902. At this time, the rotating plate 903 is pulled out of the outer wall of the rectangular plate 901, and the limiting rod can enter the inner wall of the rectangular plate 901. When the pull rod 904 is pulled again, the pull rod 904 drives the rotating plate 903 to rotate on the inner wall of the circular shaft 902. At this time, the rotating plate 903 can clamp the limiting rod, thereby preventing the connecting plate 8 and the self-locking component 9 from detaching, so that the support block 1 6 and the support block 2 10 cannot fix the square plate 5.

[0030] In a preferred embodiment: the scraping assembly 11 includes a motor 1101, a three-hole gear 1102 is provided on the top of the motor 1101, the outer wall of the three-hole gear 1102 is engaged with a five-hole gear 1103, the top of the five-hole gear 1103 is fixedly installed with a fan-shaped tooth plate 1104, the outer wall of the fan-shaped tooth plate 1104 is engaged with a rack 1105, and the top of the rack 1105 is fixedly installed with a scraper 1106.

[0031] In a preferred embodiment: the power output shaft of the motor 1101 is connected to the three-hole gear 1102 through a circular groove opened on the outer wall of the square plate 5, the outer wall of the scraper 1106 is slidably connected to the inner wall of the pipe 2 through a sliding groove opened at the bottom of the pipe 2, and there are two groups of five-hole gears 1103 and fan-shaped tooth plates 1104, and the rotation directions of the two groups of fan-shaped tooth plates 1104 are the same.

[0032] In the above structure, the power output shaft of the motor 1101 drives the three-hole gear 1102, so that the three-hole gear 1102 can drive the two groups of five-hole gears 1103 to rotate, so that the five-hole gear 1103 can drive the fan-shaped tooth plate 1104 to rotate. Since the two groups of fan-shaped tooth plates 1104 have the same rotation direction, when one group of fan-shaped tooth plates 1104 is engaged with the rack 1105, the other group of fan-shaped tooth plates 1104 is not engaged with the rack 1105. At this time, the rack 1105 is driven to push forward. When the fan-shaped tooth plate 1104 rotates to no longer engage with the rack 1105, the other group of fan-shaped tooth plates 1104 is engaged with the rack 1105, so that the rack 1105 is driven backward, so that the rack 1105 can drive the scraper 1106 to scrape off the blocked debris in the inner cavity of the pipe 2.

[0033] Working principle: The controller 3 is electrically connected to the motor 1101, so that when the scraping component 11 needs to start working, you only need to press the controller 3. At this time, the controller 3 can control the motor 1101, so that the motor 1101 can drive the scraping component 11 to work, and the three-hole gear 1102 is driven by the power output shaft of the motor 1101, so that the three-hole gear 1102 can drive the two groups of five-hole gears 1103 to rotate, so that the five-hole gear 1103 can drive the fan-shaped tooth plate 1104 to rotate, and the two groups of fan-shaped tooth plates 1104 have the same rotation direction. When one group of fan-shaped tooth plates 1104 is engaged with the rack 1105, the other group of fan-shaped tooth plates 1104 is not engaged with the rack 1105. At this time, the rack 1105 is driven to push forward, and when the fan-shaped tooth plates 1104 rotate to no longer engage with the rack 1105, the other group of fan-shaped tooth plates 1104 engages with the rack 1105, so that the rack 1105 is driven backward, so that the rack 1105 can drive the scraper 1106 to scrape the blocked debris in the inner cavity of the pipe 2. By pulling the pull rod 904, the pull rod 904 can rotate on the outer wall of the rectangular plate 901, so that the pull rod 904 can drive the rotating plate 903 to rotate on the outer wall of the circular shaft 902. At this time, the rotating plate 903 is pulled out of the outer wall of the rectangular plate 901, and the limit rod can enter the inner wall of the rectangular plate 901. When the pull rod 904 is pulled again, the pull rod 904 drives the rotating plate 903 to rotate on the inner wall of the circular shaft 902. At this time, the rotating plate 903 can clamp the limit rod, thereby preventing the connecting plate 8 and the self-locking component 9 from disengaging, so that the support block 1 6 and the support block 2 10 cannot fix the square plate 5, so that the scraping component 11 can be fixed to the bottom of the pipe 2.
