Abstract
A belt compressor filter belt correcting device belongs to the field of dynamoelectric automation technology. A bias-adjusting roll contacting with the filter belt is arranged on the lower portion thereof, a left and a right spacing overtravel-limit switches are arranged on both sides of the filter belt, the utility model is characterized in that a movable carriage contacting with the filter belt is arranged on the lower portion thereof, a left and a right approach switches are arranged on both sides of the movable carriage and the right approach switch, the left spacing overtravel-limit switch and a right shift relay which are cascade are connected in parallel with the left approach switch, the right spacing overtravel-limit switch and a left shift relay. The correcting device has the filter actual position to be the criterion of alternative filter belt centering and the bias-adjusting roll only executes the bias-adjusting function, thereby the judgment is accurate without producing bias-adjusting mistakes.
Description
The utility model belongs to the electromechanical automatic technical field, mainly is meant a kind of belt press strainer deviation correcting device.
The strainer correction control of existing belt press drives regulating roller by the oil pressure offset adjustment cylinder and realizes.Regulating roller places under the strainer, and touches mutually with strainer, and the friction that produces when the relative motion with strainer and regulating roller realizes the tuningout control to strainer.Regulating roller one end is fixed on the fulcrum that can freely swing along the horizontal direction of strainer transmission, the other end near be provided with near switch.Two ends, the strainer left and right sides are provided with left and right sides limitation travel switch respectively.This device weak point is to move to regulating roller to be considered as strainer when becoming vertical with strainer and to be in correct middle position, is to judge whether correct foundation placed in the middle of strainer, and be again concrete correction parts.Because the influence of factors such as strainer unbalance stress, installation deviation, coefficient of friction variation causes the tuningout error in actual use, and error accumulates one by one, causes strainer super inclined to one side and can't work at last.
The utility model purpose is to overcome the deficiencies in the prior art, by be provided with separately movable carriage and corresponding two near switch, design provides a kind of belt press strainer deviation correcting device.
Described belt press strainer deviation correcting device, the strainer both sides are provided with right limit travel switch and left limit travel switch respectively, the strainer bottom is provided with and its regulating roller that touches mutually, regulating roller one end is movably connected on the fulcrum that can freely swing along the horizontal direction of strainer transmission, it is characterized in that the strainer bottom is provided with and its movable carriage that touches mutually, the movable carriage two ends are respectively equipped with right near switch and left near switch, and are right near switch, the left limit travel switch, after the relay that moves to right is connected a mutually and left side is near switch, the right limit travel switch, move to left and be connected in parallel after relay is connected mutually.
This belt press strainer deviation correcting device has been set up movable carriage, and as strainer distinguishing rule placed in the middle, and regulating roller is only carried out the tuningout function with physical location.Therefore, accuracy of judgement can not produce the tuningout error.
The utility model is described in further detail below in conjunction with Figure of description.
Fig. 1 is a belt press strainer deviation correcting device structural representation;
Fig. 2 is the electric control schematic diagram.
This device for mechanical structure and electric control theory structure are as described above.The right side is installed in respectively near on the fixed position of 2 two end points of movable carriage near switch Jxwk2 near switch Jxwk1, a left side, by two end points displacements near switch surveillance operation planker 2, has also promptly monitored the left and right sides side-play amount of strainer.Left and right two a pair of normally-closed contacts near switch are controlled the power supply of the control circuit that moves to right and move to left respectively.Strainer produces in running when being offset to the left or to the right, drives movable carriage and also slides to the left or to the right, connects to the right or tuningout control circuit power supply left by left and right normally-closed contact near switch.When side-play amount arrives to a certain degree greatly, when meeting the left limit travel switch xwk2 that is arranged at the strainer both sides or right limit travel switch xwk1, then pick up strainer offset error signal by left and right sides travel switch, this error signal feeds back to tuningout by control circuit and carries out relay: the relay J that moves to left 22 or the relay J 21 that moves to right, start the tuningout magnetic valve by the move to left relay J 22 or the relay J 21 that moves to right again, carry out tuningout by 3 pairs of strainers of regulating roller, strainer is pulled back from deviation post, until strainer is when being pulled accurate middle position, near the switch adhesive, its normally-closed contact will be controlled dump, the tuningout release.
