Description
Technical field
The present invention relates to a kind of slip pressing mechanism, especially relate to a kind of slip pressing mechanism for the slip pressurizing continuous solid-liquid separating machine, belong to parts in the slip pressurizing continuous solid-liquid separating machine.
Background technology
Water treatment plant, paper mill, food processing factory, chemical plant and plant etc. all will produce a large amount of materials that needs processed.These materials are through dehydration, after being concentrated again landfill can save a large amount of soils, reduce sewage permeation; Simultaneously, many organic materials in these materials are when being concentrated to certain solid content, just can be directly used in comprehensive utilization, thereby save the oven dry energy, such as the solid content of paper-making deinking mud is pressed dry 50% when above, just not needing can realize the burning of postcombustion, its incineration residue can be used as the cement raw material of high-quality.
It was on 03 21st, 2007 as open day, publication number is CN2880216, the patent No. is to disclose " a kind of high-efficient strong filter press " in 200620100437.3 Chinese patent, this high-efficient strong filter press is a kind of board-like filter press that combines with belt filter press, it is that the multilayer filter press plate is stacked, material is passed through the clamping of two circulating net bands around the S-shaped trend of filter press plate, by the hydraulic system pressed.This technology has solved traditional chamber-type press filter filter cloth cleaning, the time-consuming problem of filter cloth replacing, and still, still there are the following problems for it.
1, owing to adopting the hydraulic reciprocating pressurization, so can only take intermittently operated, tape transport, pressing, discharging must be carried out step by step, so inefficiency.In addition, also because be the reason of intermittently operated, make cloth be difficult to evenly, and then cause squeezing effect and differ.
2, because its squeezing pressure provides by hydraulic cylinder fully, and the stroke of hydraulic cylinder is limited, so the filter plate quantity of every equipment is difficult to compare with traditional chamber filter press, such as common plate type pressure filter can be accomplished 100 blocks more than plate, and this utility model is generally in 10 blocks of plates left and right, to improve output, to reduce equipment manufacturing cost all very unfavorable.
Aspect the high dehydration of continuous operation filtering equipment pressure, it was on December 20th, 2006 as open day, publication number is CN1879932, the patent No. is to disclose " a kind of belt filter press " in 200610050778.9 Chinese patent, thereby this belt filter press provides high-tension to improve the technology of dehydration pressure by steel strip, its dehydration pressure is up to 3.0Mpa, obtained substantial progress aspect heavy sludge filter cake solid content as before improving the larger material ratio of frictional force; But for the material of stick-slip character, such as municipal activated sludge, so high squeezing pressure will inevitably cause sideslip and the difficult feed of material, is difficult to carry out effective squeezing.
In sum, due to the slip pressing mechanism that is used for solid-liquid separating equipment that also there is no a kind of dependable performance at present, can adapt to the stick-slip material dewatering and move continuously, thereby reduced the performance of solid-liquid separating equipment, brought larger inconvenience also for the material that separates stick-slip character.
Summary of the invention
