The rammer board face periphery of described the first rammer board is provided with transition triangle circle, and at the rammer board face periphery covering protection pad of flange circle and the first rammer board, described protection pad is connected with flange circle.
Owing to adopting technical scheme of the present invention, dewater in the rammer board group neighboring of wherein of the present invention is directly surrounded by flange circle that can elastic displacement, flange circle protrudes from rammer board front simultaneously and matches with the boss circle front of another piece rammer board, the peripheral sealing in sludge dewatering chamber and the sludge dewatering chamber variable volume when press dewatering have been realized, thus, greatly simplified the fit structure between the rammer board in rammer board group, processing is more prone to, cost is lower, relative motion during operation between rammer board is more stable, improve press dewatering effect.
Accompanying drawing explanation
Fig. 1 is the generalized section of dehydration rammer board group embodiment provided by the present invention.
Fig. 2 is that dewater shown in Fig. 1 periphery of rammer board group coordinates enlarged diagram.
Fig. 3 is the state evolution schematic diagram of the embodiment shown in Fig. 1 in press dewatering process.
The specific embodiment
With reference to accompanying drawing.The present invention includes the rammer board that polylith is arranged in parallel and can moves forward and backward along orientation, described rammer board is driven mobile by hydraulic power supply; Described rammer board comprises the first rammer board 1 and 2 two kinds of rammer boards of the second rammer board, the first adjacent rammer board and the second rammer board form dehydration rammer board group, during manufacture, can be according to user's production capacity needs, the dehydration rammer board group of varying number is set in described deep dehydration device for sludge, described the first rammer board 1 and the second rammer board 2 are arranged alternately in deep dehydration device for sludge, form the sludge dewatering chamber 100 of variable volume one by one.
The flange circle 3 that the neighboring of described the first rammer board is slidably connected and can seesaws, described flange circle protrudes from the rammer board face 10 of the first rammer board, and described dehydration rammer board group is provided with the elastic supporting part of flange circle; The second 2 of plates are notch board, and the periphery of the second rammer board 2 is boss circle 20; The rammer board face 10 of the first rammer board and the second rammer board Ao district 21 are face-to-face, described boss circle 20 and flange circle front 30 offset and between their front, form sealing, after boss circle 20 and flange circle front 30 offset, because flange circle 3 can move forward and backward, the sludge dewatering chamber variable volume forming between the rammer board of dehydration rammer board group.
The sealing forming between described boss circle 20 and flange circle 3 fronts can be directly itself be coordinated and forms by their, such as the surface of flange circle has elaxtic seal, or in their front, is provided for the material of sealing.In the present embodiment, the front of described flange circle arranges protection pad 4, the sealing 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 described the first rammer board a pair of flange circle 3 seesawing that is slidably connected, described a pair of flange circle 3 is arranged before and after along rammer board orientation, and protrude from respectively the front and back rammer board face of the first rammer board, between described a pair of flange circle 3, described elastic supporting part is set, described the second rammer board 2 is two-sided notch board.Described the first rammer board 1 is by 2 superimposed being formed by connecting of plate.
The inner side of described a pair of flange circle 3 arranges spring base 50, and described elastic supporting part is spring 5.
The neighboring of described the first rammer board is provided with cannelure 11, and described flange circle 3 is provided with annular installation foot 31, and described installation foot is slidably disposed in cannelure, and the inner ring surface 32 of described flange circle forms slide-and-guide with the neighboring of the first rammer board 12 and coordinates.
The rammer board face periphery of described the first rammer board is provided with transition triangle circle 6, and at the rammer board face periphery covering protection pad 4 of flange circle and the first rammer board, described protection pad 4 is connected with flange circle 3.Do like this, in the time of can making the transition of filter cloth 73 between the first rammer board 1 and the flange circle 3 that protrudes, have a buffering, prevent filter cloth and because of the volume-variation in sludge dewatering chamber, cause its breakage when equipment high pressure is compressed into.
Water conservancy diversion on each rammer board adopts circular bosses 71 one by one, and circular bosses 71 is covered with the filter bed 72 that supports use above, and filter bed 72 is outer arranges filter cloth 73 again, like this, can prevent that hypertonia from causing the breakage of filter cloth 73.
As shown in Figure 3, left side component shown rammer board being driven by hydraulic jack state or the dump state before compressing.After middle component has shown that hydraulic jack is compressed into for the first time with the pressure below pressure 1Mpa, between rammer board, preliminary the first state compressing while forming sludge dewatering chamber, now can enter mud with pump.The right component has shown the second state after hydraulic jack is compressed into for the second time with the pressure (mud pressure 3-5Mpa) of pressure 20-25Mpa.From the first state to the second state, be that high pressure is pressed mud process, after squeezing, dump moisture content is between 30-50%.
