Description

Technical Field

[0001] This utility model relates to wastewater treatment equipment, specifically, to a bar screen device for wastewater treatment. Background Technology

[0002] Wastewater treatment tanks often incorporate bar screens to trap large solid particles such as branches, plastics, and fabrics, preventing them from entering subsequent treatment stages and avoiding equipment blockage or damage. For example, Chinese patent CN212198542U provides a bar screen device for wastewater treatment, including a barrier bar plate with a scraping mechanism on its front side. This scraping mechanism comprises two symmetrical connecting plates located on either side of the barrier bar plate. First grooves are symmetrically formed on the opposing sidewalls of the connecting plates, and a first sliding plate is positioned between the two connecting plates. First sliders are symmetrically positioned at both ends of the first sliding plate and are slidably connected to the first grooves. One of the first sliders has a threaded hole on its top surface. In such prior art bar screen devices, when scraping away foreign objects from the bar plate surface, the objects can easily fall back into the waterway, affecting the normal water flow. Utility Model Content

[0003] The purpose of this invention is to provide a bar screen device for wastewater treatment, which solves the problem in the prior art where foreign objects easily fall back into the waterway when the surface of the bar screen is scraped off, thus affecting the normal water diversion of the waterway.

[0004] To achieve the above objectives, this utility model provides a bar screen device for wastewater treatment. The bar screen device includes a bar screen plate disposed in a water channel. The bar screen plate has multiple vertically spaced through slots. A first cylinder is disposed at the upper end of the bar screen plate. The piston rod of the first cylinder is connected to a base plate, allowing the base plate to move up and down on the surface of the bar screen plate. A rotating shaft is rotatably disposed on the edge of the base plate. Multiple inclined plates are spaced on the rotating shaft, and the plates pass through the through slots. A torsion spring is sleeved on the end of the rotating shaft. One end of the torsion spring is fixed to the rotating shaft, and the other end is fixed to the base plate. A sliding seat is horizontally displaceable at the upper end of the water channel. Multiple push rods are spaced on the sliding seat, allowing the push rods to contact the plates.

[0005] Preferably, a second cylinder is provided on the outside of the waterway, and the piston rod of the second cylinder is connected to the sliding seat.

[0006] Preferably, pulleys are rotatably provided at both ends of the sliding seat, and the pulleys are in contact with the upper end of the waterway.

[0007] Preferably, a third cylinder is provided on one side of the waterway, and a push plate is connected to the piston rod of the third cylinder. The push plate can be displaced along the width direction of the waterway to push out foreign objects on the bottom plate.

[0008] Preferably, a collection box is provided on the side of the waterway away from the third cylinder.

[0009] Preferably, a hook is provided on the outside of the waterway, and a hook groove is provided on the collection box to cooperate with the hook.

[0010] Beneficial Effects: This utility model provides a bar screen device for wastewater treatment. The bar screen device includes a bar screen plate disposed in a water channel. The bar screen plate has multiple vertically spaced through slots. A first cylinder is disposed at the upper end of the bar screen plate. The piston rod of the first cylinder is connected to a base plate, allowing the base plate to move up and down on the surface of the bar screen plate. A rotating shaft is rotatably disposed on the edge of the base plate. Multiple inclined plates are spaced on the rotating shaft. The plates pass through the through slots. A torsion spring is sleeved on the end of the rotating shaft. One end of the torsion spring is fixed to the rotating shaft, and the other end is fixed to the base plate. A sliding seat is horizontally displaceable at the upper end of the water channel. Multiple push rods are spaced on the sliding seat, allowing the push rods to contact the plates. During operation, initially, the base plate is located at the bottom of the waterway, and the grating plate can intercept foreign objects in the waterway. When it is necessary to clean foreign objects from the grating surface, the first cylinder drives the base plate to move upward, and the plate on the base plate can push the foreign objects to the upper end of the grating plate from bottom to top. Then, the displacement sliding seat causes the push rod on it to push the plate to rotate, thereby pushing the foreign objects on the grating plate into the base plate, preventing the foreign objects from falling back into the waterway. The wastewater treatment grating device provided by this utility model can not only effectively intercept foreign objects in the waterway, but also easily clean the foreign objects intercepted on the grating surface, ensuring unobstructed waterway flow.
