Description

Technical Field

[0001] The utility model belongs to the technical field of grille machines, in particular to an elliptical stacked grille machine. Background Art

[0002] The screen machine is a solid-liquid separation equipment that can continuously remove impurities in the fluid. In the front process of sewage treatment, it intercepts and removes various solid particles, floating objects, etc. It is currently a solid-liquid screening equipment commonly used in China. The screen mesh is composed of screen teeth, screen tooth shafts, chain plates, etc., to replace the bars of the traditional screen. The screen mesh rotates back and forth in the frame, thereby intercepting the suspended matter in the sewage and continuously separating it from the water surface. The screen residue falls into the residue bucket by the rotating brush. The screen machine is an indispensable special equipment in the production process of urban sewage treatment, water plants, power plant water inlets, textiles, food processing, papermaking, leather and other industries. It is a solid-liquid screening equipment commonly used in China.

[0003] For example, a Chinese patent with publication number CN217549148U discloses an elliptical dehydrator, comprising a bracket, wherein a first placement plate is arranged on the inner side of both ends of the bracket, and a second placement plate is arranged on the inner side of the front and rear ends of the bracket; a rotating shaft is arranged on the inner side of the first placement plate, and an elliptical assembly is fixedly sleeved on the outer side of the rotating shaft; the bracket and the front second placement plate are combined to form a feed inlet, and the rear second placement plate and the bracket form a discharge outlet; a filter screen and an elliptical assembly are arranged, wherein the filter screen is composed of a plurality of groups of wedge-shaped bars, and a filter groove is formed between each two adjacent groups of wedge-shaped bars to facilitate the passage of filtered water, and the elliptical assembly is formed by a plurality of groups of elliptical sheets, wherein the positions of the elliptical sheets correspond to the filter grooves, and during the rotation of the elliptical assembly, the elliptical sheets rotate and dredge in the gaps between the wedge-shaped bars, and the solids remaining in the gaps between the wedge-shaped bars are pushed to the terminal outlet, thereby achieving the effect of solid-liquid separation.

[0004] For example, a Chinese patent with publication number CN206051588U discloses a screen machine, including a frame, wherein the lower end of the frame is close to one end of the sewage inlet and baffles for guiding sewage are respectively arranged on both sides, and the baffles include a fixed plate connected to the frame and a movable plate connected to the fixed plate, and a fixing piece is arranged between the movable plate and the fixed plate. This scheme adopts a new mechanical structure. The utility model has the following advantages and effects: baffles are arranged on both sides of the frame to guide the sewage so that the sewage can pass through the filtration of the screen machine, and the setting of the fixed plate connected in the card slot realizes the movement of the fixed plate, and adjusts the length of the baffle outside the screen machine to adapt to different installation environments. The distance between the movable plates movably connected to the fixed plate can be changed, thereby changing the size of the opening for guiding the sewage, adapting to different installation environments, and achieving complete guidance of the sewage, so that no sewage will be discharged without being filtered.

[0005] The above two patents have some shortcomings when used, such as: the device in the patent with publication number CN206051588U filters the solids in the sewage by placing the elliptical combination above the filter screen. When fixed impurities or sludge fall onto the filter screen below, when the elliptical combination rotates, the solids or sludge on the wedge-shaped gap on the back of the elliptical combination will be squeezed by the elliptical combination and pressed into the wedge-shaped groove, and some solids or sludge fall into the collection box below, resulting in poor filtration efficiency. In addition, the device directly filters the sewage without flocculating the sewage, and cannot effectively filter the fine sediment in the sewage. The overall filtration effect of the device is poor; the device in the patent with publication number CN206051588U can only intercept the suspended matter in the sewage, but cannot effectively filter the sewage. The scope of application and filtration range are low, and it cannot meet the market demand. In view of this, we propose an elliptical grid machine. Utility Model Content
