Description
Patent application of the present invention relates to workshop-sink, the technical field of the force feed device construction of using when class high-viscosity fluids such as mud, cement slurry are handled.
As everyone knows, along with industrial development, in the factory that produces various manufacturing mechanisms, discharging refuses such as a large amount of wastes, waste oil, mud, and this public hazards processing is being attached great importance to as the indispensable countermeasure of industrial development institute.Wherein the processing to high-viscosity fluids such as the mud of earth shape, mud is to carry out solid-liquid separation, the burning of the solid matter that obtains after the separation by regulation, bury etc. and to be handled, waste liquid is then sought regeneration etc. adopt above-mentioned technology widely, but the force feed device that is used for this processing has been used big capacity from the Processing capacity grade, the various devices of high output, strong durability.
It is as follows that this force feed device has been extensive use of force feed device 1 its action for example shown in Figure 3: the elastic membrane 3 that the inflatable contraction of material systems such as rubber is housed in the barrel-shaped casing 2, by oil pressure generating device 4 working oil 5 is arranged to above-mentioned elastic membrane 3 confessions, and compress, expand from the inboard pressures cycle ground that produces of elastic membrane 3, thereby being inhaled in mud pit 7 the back road treatment device 8 such as being pressed to pressure filter in the casing 2 again, goes processed liquid 6 such as mud.
Then, partly be removed with the form of bulk via the solid of the mud 6 of solid-liquid separation gained, liquid is partly discharged through the clarification back is suitable, perhaps gives effective utilization again.
Yet, have following shortcoming: a kind of in this way that class waste liquid that contains chemicals or microorganism of promptly processed liquid, then in casing, deposit for a long time, during can fermentation and make and be mixed with bubble in the waste liquid, and when this processed liquid was high viscosity, the degassing was very difficult naturally.When for example using above-mentioned the sort of force feed device force feed processed liquid as described above, because the structure of casing 2 is to carry out opening and closing by the check valve of adorning between it and the mud pit 7, therefore sneak into bubble 10 in the suction process, 10 ... and owing to this bubble in casing 2 is that constrictive set is present in inside, and produce partly empty, even elastic membrane 3 is compression-expansion fully, because of this empty volume change has produced the damping function that hinders propagation of pressure, mud 6 can not fully be pressed to down the treatment device 8 of operation in casing 2.
Further, even make suction/exhousting hole be positioned at top casing 2 vertical installations, because mud 6 can be sucked naturally sometimes, so when this mud is high viscosity, bubble is the mud 6 in the crushed suction casing 2 when attracting, actual mud intake deficiency causes the force feed device can not carry out the force feed of uniform and stable.
In addition, when force feed device 1 running,,, and make force feed device 1 become the condition of high temperature, make the Sealing fatigue of pipeline junction and reduced working life so the temperature of the bubble 10 of delay state rises because of mud compresses in casing 2 repeatedly.
Therefore the force feed device of so-called plunger type type only limits to force feed and does not contain the processed liquid that becomes material and bubble, and the inapplicable all liquid waste processing that contain high viscosity liquid.
In addition, because be between the outside of elastic membrane 3 and casing 2, mud 6 to be carried out suction,, can't carry out the abundant suction of high viscosity liquid so elastic membrane 3 is carried out the contraction program and produced negative pressure when sucking, this elastic membrane makes elastic membrane 3 tired easily because of fold takes place, and this also is a kind of deficiency.
First purpose of patent application of the present invention is that the shortcoming that exists when the force feed viscous liquid with the force feed device that solves above-mentioned prior art is a technical task, the processed liquid that it can not only be with various factories, build the sort of waste liquid of discharging in the place or mud class also can with contain medium-term and long-term placement of underground tank of factory etc. the composition that produces bubble high-viscosity fluid for degassing difficulty be sent to reliably high pressure under operation.Second purpose of the present invention is to carry out the high efficiency row of giving to the liquid in the casing with plunger and elastic membrane.The 3rd purpose of the present invention provides and helps the force feed device of good viscous fluid that various industries aspect prevents the technical field of public hazards.
