Description

Technical Field

[0001] This utility model belongs to the technical field of bar screen cleaning equipment, specifically relating to a bar screen cleaning machine with a crushing device. Background Technology

[0002] Bar screens are devices used to filter pollutants from water storage devices such as pools and ponds. During the removal process, the rotating bar screen adheres to and transports pollutants, achieving the purpose of removal. Existing bar screens include rotary drum bar screens, rotary bar screens, and direct current bar screens. Currently, rotary drum bar screens generally cannot effectively crush the collected impurities, easily leading to blockages and screen jamming. Furthermore, during transport, some longer or larger impurities can become entangled in the feeding screw, causing mechanical damage or blockages and reducing removal efficiency. Additionally, the collected waste still requires further crushing after transport, resulting in high equipment costs. Therefore, a bar screen with a crushing device is needed to solve these technical problems. Utility Model Content

[0003] To address the aforementioned deficiencies in the existing technology, this utility model provides a bar screen cleaning machine with a crushing device, comprising a rotating drum connected to a stepper motor; the rotating drum includes a first connecting plate, a second connecting plate, and a cylindrical bar screen, the two ends of which are rotatably connected to the first connecting plate and the second connecting plate via bearings, the first connecting plate having a sewage inlet communicating with the bar screen, multiple material plates fixed circumferentially on the inner wall of the bar screen, and a ring of toothed racks fixed on the outer wall of one end of the bar screen, the racks meshing with a transmission gear, the transmission gear being connected to the stepper motor;

[0004] The grid contains a cylindrical crushing box, the central axis of which coincides with the central axis of the grid. One end of the crushing box is sealed to the first connecting plate, and the other end is fixedly connected to the second connecting plate. The second connecting plate is connected to a screw feeder, which includes a feeding pipe and a first feeding screw located inside the feeding pipe. One end of the first feeding screw is connected to a rotating motor. The diameter of the feeding pipe is smaller than the diameter of the crushing box, and the feed end of the feeding pipe communicates with the crushing box. The top of the crushing box has an impurity inlet, and the bottom of the crushing box is covered with permeable holes. The crushing box contains a crushing assembly, which includes a rotating rod and crushing blades. One end of the rotating rod is fixedly connected to the first feeding screw, and the crushing blades are fixed on the rotating rod. The crushing blades include a first blade and a second blade. The first blade is spirally distributed on the rotating rod and cooperates with the crushing box to form the second feeding screw. This structure can crush impurities while transporting them to the screw feeder. The blade body of the second blade is perpendicular to the rotating rod.

[0005] Preferably, a cleaning component is provided above the grille, the cleaning component is vertically aligned with the impurity inlet, the cleaning component includes a water inlet pipe and a water spray head, the water inlet pipe is connected to the water spray head, the water spray head faces the grille and the impurity inlet, and the water inlet pipe is connected to a water pump.

[0006] Preferably, the cleaning assembly further includes a horizontal screw, with each end of the horizontal screw rotatably connected to a bracket via bearings. The lower ends of the two brackets are fixedly connected to connecting plate one and connecting plate two, respectively. A guide rod parallel to the horizontal screw is fixed between the two brackets. The spray head is connected to a slider, which is threaded into the horizontal screw. The slider has a guide hole through which the guide rod passes. One end of the horizontal screw is connected to a reversible motor, and the water inlet pipe is a retractable spring tube. The reversible motor drives the spray head to reciprocate along the horizontal screw, while the spray head continuously sprays water to rinse the grille.

[0007] Working principle: Wastewater enters the space between the screen and the crushing box through the wastewater inlet. The stepper motor drives the screen to rotate. Impurities in the wastewater are picked up by the material plate and rotated to fall above the impurity inlet. The impurities enter the crushing box, are crushed, and then transported away by the screw feeder and discharged from the screw feeder outlet for further treatment. After being filtered by the screen, the wastewater is discharged from the side wall of the screen.

[0008] When the bar screen needs cleaning, the spray head box sprays high-pressure water to blow the impurities stuck to the bar screen into the crushing box for crushing and transportation away.

[0009] When using it, the drum can be tilted as needed.

[0010] This utility model also includes other components that enable the normal operation of a bar screen with a crushing device, such as control components for a stepper motor, control components for a forward and reverse motor, control components for a rotary motor, control components for a water pump, and control components for a spray head, all of which are conventional technologies in the field. Furthermore, devices or components not limited in this utility model, such as spray heads, water pumps, screw feeders, bar screens, and feeding screws, all employ conventional technologies and equipment in the field.
