Abstract
The utility model relates to the improvement of a filter screen offset-adjustable device of a belt filter press. The utility model is characterized in that the rectifying roller is arranged with no deflection angle; two detecting devices are arranged on the two sides of the filter for detecting whether the filter deflects or not; the offset-adjusting cylinder is a double-acting cylinder that can expand and contract towards two directions; compared with the prior art, the rectifying frequency of the filter screen is reduced greatly and the rectifying movement is small, the service lives of the vulnerable parts and the whole device are prolonged; in addition, during the rectifying process, the deflection of the rectifying roller is small, the situation that one side is tight and the other side is loose of the filter screen does not happen, pressing and filter pressing are good and both the filter screen and bearing are not vulnerable; finally, because of the rectifying movement is mall, i.e. the rectifying frequency is reduced, a belt filter press with large width, 3 meters or longer, can be made; the offsetting detect of the two sides of the filter screen can effectively control the bidirectional deflecting condition.
Description
Technical field
Utility model is about the improvement to the one-sided limit of belt filter press filter screen deviation correcting device.
Background technology
Belt filter press in use, therefore sideslip takes place through regular meeting in filter screen, and strainer offset detection and deviation correcting device all are installed.The filter press filter screen entangles (accent) deflection device at present, more employing be that one-sided frontier inspection is surveyed, correction, promptly offset detection 3 and deviation correcting device are set at filter screen 4 one sides, and the roller 5 of will rectifying a deviation presets a deviation angle, filter screen is moved to a direction, according to detecting sideslip, one-sided adjusting correction roller is rectified a deviation, and it is to adopt single-ended telescopic cylinder 2 to move back and forth correction (as Fig. 1,2) that the correction roller is regulated.This correction roller presets deviation angle and single-ended telescopic cylinder adjustment correction, and filter press work promptly produces the strainer skew and needs correction, and the correction displacement is big, cause correction to act frequently, not only cause correction pneumatic control system frequent operation, reduction of service life, and also the frequent of correction roller moves, one side pine when easily causing the filter screen operation, one side is tight, and not only the mud effect is pressed in influence, and damages filter screen easily, and cause the roll shaft discontinuity, shorten bearing service life; Secondly, to preset side-play amount big along with the filter press filter screen is widened for the correction roller, it is frequent especially to rectify a deviation, the problems referred to above have not only been increased the weight of, roll over crape but also can cause filter screen to move and not catch up with to produce, cause filter screen to damage, so this kind deviation correcting device has limited the increase of filter press width, the general Breadth Maximum of belt filter press can only be accomplished 2.5 meters at present, has limited filter press to large scale development.
In addition, correction is surveyed, adjusted to one-sided frontier inspection, is offset round about in case produce filter screen, then can't rectify a deviation, and can only shut down the machine cisco unity malfunction, can damage filter screen when serious.
Though prior art has and adopts the strainer both sides to detect and bilateral single-ended telescopic cylinder correction is set all, because of single-ended telescopic cylinder correction, the correction roller still need preset a deviation angle, and above-mentioned defective still exists, and has just solved the correction adjustment when being offset round about.
Therefore existing filter press filter screen correction has become the high big reason of filter press fault rate, reaches the big obstacle to large scale development.
Summary of the invention
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of correction frequency low, and the correction displacement is little, the equipment dependability height, and can be fit to the belt filter press filter screen deviation correcting device of big width.
The utility model purpose realizes that main the improvement is that the correction roller adopts no drift angle (coaxial line) to be provided with, and adopts the flexible double-acting cylinder of both direction to drive correction, thereby overcomes the deficiencies in the prior art, realizes the object of the invention.Specifically, utility model belt filter press filter screen deviation correcting device, comprise that the strainer sideslip detects, correction roller and connection correction roller tuningout cylinder, it is characterized in that said correction roller does not have the drift angle and is provided with, said strainer sideslip detects to the strainer both sides are provided with checkout gear, and said tuningout cylinder is the flexible double-acting cylinder of both direction.
The said double-acting cylinder of utility model is meant that cylinder can realize axial both direction expanding-contracting action, and two kinds of basic structures can be arranged, and a kind of is that two single-ended flexible leaning against are provided with combination, realizes can both stretching to axial two ends; A kind of is telescopic with two steps of end, promptly after front stretching retreats to mid point, can stretch backward and return mid point.Both are easy installation realizing not having essential distinction on the function, and utility model preferably adopts the latter.
Utility model belt filter press filter screen deviation correcting device owing to adopt said structure, has overcome the intrinsic theory that always adopts single-ended telescopic cylinder correction and correction roller off-axis line to be provided with for a long time, and the deficiency of bringing thus for a long time.Have than prior art: the correction roller does not have drift angle (coaxial line) and is provided with, and two-way mobile correction, not only greatly reduce filter screen correction frequency, and the correction amount of movement is little, overcome because the defective that the high-frequency correction brings, improve the reliability of equipment, prolonged fragile parts service life, thereby improved complete machine service life; Secondly, correction roller side-play amount is little during tuningout, tight on one side, the loose phenomenon in one side that filter screen is not prone to, and the press filtration quality is good, and filter screen and bearing are not fragile; Besides, because the correction amount of movement is little, and the reduction of correction frequency, can make big width strainer filter press, can make width is 3 meters or wideer strainer formula filter press; Filter screen both sides sideslip detects, and two-way sideslip all can be effectively controlled.
Below in conjunction with an optimization specific embodiment, further specify utility model, but embodiment should not be construed as the limitation and restriction to utility model.

Fig. 3 is an embodiment tuningout structural representation.
Fig. 4 is Fig. 3 side-looking structural representation.
The specific embodiment
Embodiment: referring to Fig. 3,4, utility model belt filter press filter screen deviation correcting device comprises being arranged on the frame 1, with the concentric correction roller 5 that does not have the drift angle of axis, respectively there are offset detecting device 3.1 and 3.2 in filter screen 4 both sides, and correction roller one end is connected with the formula of leaning against with telescopic double-acting cylinder 7 of two step of end.
Send unidirectional offset signals when sideslip detects 3.1 or 3.2, drive the formula that leans against, make to depart from the correction roll axis and move correction to the left or to the right with telescopic double-acting cylinder 7 of two step of end.
In addition, embodiment can also adopt two single-ended flexible double-acting cylinders that combination is set that lean against.
For convenience of description, the said correction of utility model, tuningout are synonym.
