Embodiment
With reference to accompanying drawing.The present invention includes the rammer board that polylith is arranged in parallel and can move forward and backward along orientation, described rammer board is driven by hydraulicefficiency power unit and moves; Described rammer board comprises first rammer board 1 and 2 two kinds of rammer boards of second rammer board, the first adjacent rammer board and second rammer board constitute dehydration rammer board group, during manufacturing, can be according to user's production capacity needs, the dehydration rammer board group of different quantities is set in described deeply dehydrating sludge equipment, described first rammer board 1 and second rammer board 2 are arranged alternately in deeply dehydrating sludge equipment, form the sludge dewatering chamber 100 of variable volume one by one.
The flange circle 3 that the neighboring of described first rammer board is slidingly connected and can seesaws, described flange circle protrudes from the rammer board face 10 of first rammer board, and described dehydration rammer board group is provided with the elastic supporting part of flange circle; 2 of second plates are notch board, and the periphery of second rammer board 2 is a boss circle 20; The rammer board face 10 of first rammer board and the recessed district 21 of second rammer board are face-to-face, described boss circle 20 and flange circle front 30 offset and form sealing between their fronts, after boss circle 20 and flange circle front 30 offset, since flange circle 3 can before and after displacement, the sludge dewatering chamber variable volume that forms between the rammer board of dehydration rammer board group.
The sealing that forms between described boss circle 20 and flange circle 3 fronts can be directly itself be cooperated and is formed by their, has elaxtic seal such as the surface of flange circle, perhaps the material that is provided for sealing in their front.In the present embodiment, the front of described flange circle is provided with protection pad 4, the stopping property after of described protection pad act as and increases described boss circle 20 and flange circle 3 fronts and offset.
In the present embodiment, the neighboring of the described first rammer board a pair of flange circle 3 that seesaws that is slidingly connected, described a pair of flange circle 3 is arranged before and after along the rammer board orientation, and protrude from the front and back rammer board face of first rammer board respectively, between the described a pair of flange circle 3 described elastic supporting part is set, described second rammer board 2 is two-sided notch board.Described first rammer board 1 is by 2 superimposed being formed by connecting of plate.
The inboard of described a pair of flange circle 3 is provided with spring support 50, and described elastic supporting part is a spring 5.
The neighboring of described first rammer board is provided with ring groove 11, and described flange circle 3 is provided with annular installation foot 31, and described installation foot is slidably disposed in the ring groove, and the inner ring surface 32 of described flange circle forms slide-and-guide with the neighboring of first rammer board 12 and cooperates.
