The chain drive mechanism that is used for filter press
Technical field
The present invention relates to a kind of chain drive mechanism and driving method that is used for fast formula filter press, belong to the filter press chain drive mechanism and make the field.
Background technology
Granted publication CN 1124867C, title " chain drive mechanism and the method that are used for filter press ", this chain drive mechanism is by reducing motor or stepping Shen machine, minor sprocket, first grade transmission chain, transmission shaft component, passive chain wheel component, second grade transmission chain and chain groove component constitute, minor sprocket is positioned on the axle of reducing motor or stepper motor, reducing motor or stepper motor are positioned on the back timber of support assembly, transmission shaft component is arranged in the inboard of support assembly back timber, passive chain wheel component is positioned at the back timber inboard, second grade transmission chain is positioned on the sprocket wheel of passive chain wheel component and transmission shaft component, the two ends of its second grade transmission chain are fixed on the oil cylinder hanger bracket, first grade transmission chain be enclosed within on the sprocket wheel of minor sprocket and transmission shaft component and drive under the rotation of the electric side territory stepper motor that slows down hydraulic cylinder assembly and press filtration plate assembly along the back timber reach or after move.Its weak point: the one, the minor axis oil cylinder moves and is the secondary transmission mechanism, not only complex structure, manufacturing cost height, and also energy loss is big, fault rate is high, maintenance difficult; The 2nd, the connecting axle that is positioned at the piston rod drive of minor axis oil cylinder both sides is a hanging structure, and its connecting axle is subjected to the influence of factors such as gravity, very easily drops, and can't locate with curb girder pin hole coupling; Three is that two groups of oil cylinder hanger brackets in the chain drive are connected with the minor axis oil cylinder, but because the width of minor axis oil cylinder is narrow, cause two groups of chain drive mechanisms at a distance of near excessively, the piston rod that is arranged in minor axis oil cylinder both sides is swung inevitably mobile, cause piston rod to locate with curb girder pin hole coupling.
Summary of the invention
Purpose of design: the weak point in the background technology, can guarantee that the minor axis oil cylinder moves, can guarantee the chain drive mechanism that is used for filter press and the driving method of latch in the automatic control bolt device on the wing of minor axis oil cylinder both sides and the fastening screw hole in curb girder coupling again.
Design: in order to realize above-mentioned purpose of design.1, the both sides of support assembly be used to control the reach of minor axis oil cylinder or after the setting of the chain drive mechanism that moves, be one of feature of the present invention.The purpose of doing like this is: oil cylinder in the chain drive mechanism hangs to be connected and fixed and drives the minor axis oil cylinder when wing that part drives minor axis oil cylinder both sides moves and move, because the piston of minor axis oil cylinder is connected with pressure strip, and pressure strip is connected with the filter plate assembly, therefore, when the minor axis oil cylinder chain drive mechanism drive be moved to the position locking after, can finish pressure strip the filter plate assembly is pushed, realize that the short oil cylinder replaces the long oil cylinder, pushes the purpose of filter plate assembly fast.2, the coupling design of guide groove in the bottom positioning and guiding wheel of wing end and the filter press frame curb girder is two of a feature of the present invention.The purpose of doing like this is: bottom, wing end positioning and guiding wheel, the function that had both had slip, again wing has been played the good supporting effect, solved that the minor axis oil cylinder both sides piston rod that background technology exists is unsettled, the deficiency of easy dislocation, guaranteed again the minor axis oil cylinder by track move, accurately and frame side members fastening screw hole reliably peg graft.3, the automatic control bolt device is positioned at the design of wing, is three of feature of the present invention.The purpose of doing like this is: the one, be convenient to be rigidly connected with the formation of minor axis oil cylinder; The 2nd, be convenient to hang and be connected and fixed part with oil cylinder, the 3rd, be convenient to the location of automatic control bolt device.
Technical scheme 1: the chain drive mechanism that is used for filter press, it comprises synchronous motor or stepper motor, the piston of minor axis oil cylinder is connected with pressure strip, minor axis oil cylinder bilateral symmetry is fixed with wing, the bottom of wing end be provided with positioning and guiding wheel and with filter press frame curb girder in the guide groove coupling, the automatic control bolt device is arranged on the wing and the latch of automatic control bolt device and the fastening screw hole of curb girder are complementary, two groups by drive sprocket, driven sprocket, chain and oil cylinder hang the chain drive mechanism that is connected and fixed the part formation and are located at interval at respectively on the press filtration frame, article two, the two ends of chain hang with separately oil cylinder respectively and are connected and fixed the part two ends and are connected, and two oil cylinders hang and are connected and fixed that part is connected with the wing of minor axis oil cylinder both sides respectively and be connected and fixed part drive minor axis oil cylinder by the oil cylinder suspension moves.
Technical scheme 2: the driving method that is used for the filter press chain drive mechanism, it is characterized in that: synchronous motor or stepper motor drive the drive sprocket that is positioned on the press filtration frame, two drive sprockets are when the chain by separately drives driven sprocket and rotates respectively, the oil cylinder that is used to connect chain hangs and is connected and fixed the wing that part drives minor axis oil cylinder both sides, wing drives the minor axis oil cylinder and moves along the guide groove in the filter press frame curb girder, when moving into place, be arranged in the fastening screw hole of the latch insertion curb girder of the automatic control bolt device on the wing, the minor axis oil cylinder pushes the filter plate assembly fast by pressure strip, after extruding is finished, latch in the automatic control bolt device is regained, synchronous motor or stepper motor drive drive sprocket, and two drive sprockets pass through chain separately respectively, driven sprocket and oil cylinder hang the wing and the minor axis oil cylinder that are connected and fixed part drive minor axis oil cylinder both sides and reset fast along the guide groove in the filter press frame curb girder, open the filter plate assembly.
The present invention compares with background technology, the one, the bottom positioning and guiding wheel of minor axis oil cylinder bilateral symmetry wing end reaches the design of the curb girder guide groove that mates with directive wheel, solved not only that the minor axis oil cylinder both sides piston rod that background technology exists is unsettled, the deficiency of easy dislocation, and guaranteed the minor axis oil cylinder with its flank move accurately and reliability, guaranteed to be positioned at the automatic control bolt device on the flank and the reliable grafting in frame side members fastening screw hole; The 2nd, chain drive mechanism is arranged on the wing of minor axis oil cylinder both sides, and is not only easy to connect, reliable, and twists phenomenon about having avoided the minor axis oil cylinder to cross owing to two groups of chain drive mechanism spacings in moving closely producing, and guaranteed that the minor axis oil cylinder is steadily mobile; The 3rd, it is coaxial that the axle of synchronous motor or stepper motor is designed to double end, not only realized the purpose with coaxial driven in synchronism two drive sprockets of machine, and drives structure is simple, reliable, low cost of manufacture.
