Description

Technical Field

[0001] This utility model relates to the field of anti-blocking rotary mechanical bar screen technology, specifically to an anti-blocking rotary mechanical bar screen. Background Technology

[0002] A rotary mechanical bar screen (bar screen cleaner) is a device that continuously and automatically removes debris of various shapes from fluids for solid-liquid separation. The rotary mechanical bar screen uses a set of rotating bar screen chains and a unique rake tooth device to intercept and remove debris from the fluid. As the bar screen chain rotates, the rake tooth device moves along the chain, intercepting and removing solid impurities from the fluid while allowing liquid to pass through.

[0003] Conventional mechanical bar screens inherently possess anti-clogging and cleaning mechanisms, as do rotary mechanical bar screens. However, these types of mechanical bar screens typically only have one method for cleaning impurities. Depending on the type of wastewater being treated, various types of impurities exist, such as long strips of impurities in papermaking wastewater and long strips of lightweight fabric in textile wastewater, which are difficult for conventional rotary mechanical bar screens to remove. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides an anti-clogging rotary mechanical grille.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clog-resistant rotary mechanical bar screen, comprising a water filter tank, wherein the left and right sides of the inner wall of the water filter tank are respectively fixedly connected to the left and right sides of a partition plate, a rotary mechanical bar screen body is installed on the lower surface of the inner wall of the water filter tank, a coarse filter screen is detachably connected to the front side of the inner wall of the water filter tank by bolts, the back side of the coarse filter screen is detachably connected to the front side of the partition plate by bolts, a movable frame is fixedly connected to the upper surface of the coarse filter screen, a cleaning component is provided inside the movable frame, the lower surface of the coarse filter screen is in contact with the lower surface of the inner wall of the waste discharge port, the waste discharge port is opened on the front side of the water filter tank, a waste collection box and a connecting frame are respectively installed on the front side of the water filter tank, and a draining component is provided on the upper surface of the connecting frame.

[0006] Preferably, the inner wall of the waste collection box is equipped with a drain screen, and a drain outlet is provided on the back of the inner wall of the waste collection box.

[0007] Preferably, the water filter tank has an inlet on the front, and the position of the inlet corresponds to the position of the outlet.

[0008] Preferably, the draining assembly includes two cylinders b mounted on the upper surface of the connecting frame, and the telescopic ends of the cylinders b are fixedly connected to the upper surface of the pressure plate.

[0009] Preferably, the cleaning assembly includes a slider that is slidably connected to the upper and lower surfaces of the inner wall of the movable frame. The back of the slider is fixedly connected to the telescopic end of the cylinder a. The cylinder a is mounted on the back of the partition.

[0010] Preferably, the upper surface of the water filter tank is equipped with a cover plate, and the upper surface of the cover plate is connected to one end of the water inlet pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a coarse filter to filter large impurities in wastewater. Cylinder A drives a slider to move forward along the moving frame. The slider's movement causes a brush to move in the same direction on the surface of the coarse filter. The brush cleans the impurities filtered on the surface of the coarse filter and discharges them into a waste collection box through the waste outlet. This solves the problem that conventional rotary mechanical screens are difficult to remove some impurities.

[0013] This invention uses a draining net to drain water contained in impurities. Cylinder b drives the pressure plate to move downwards and squeeze the impurities on the surface of the draining net, causing solid-liquid separation. The drained water is discharged back into the filter tank through the inlet and outlet, thus avoiding water waste. Attached Figure Description
