Abstract
The utility model discloses a full-automatic pulling plate mechanism for a pressure filter. A special motor drives a second chain wheel through a first grade transmission chain, the second chain wheel drives a third chain wheel, the third chain wheel drives a pulling plate chain and a draw hook box is connected with the pulling plate chain. A speed measurement device is arranged on the second chain wheel and connected with a programmable logic controller (PLC). The full-automatic pulling plate mechanism for the pressure filter has the advantages of being flexible in reversing, even in motion speed, stable and reliable in plate pulling and low in inverting, and being designed to be simplified in control, greatly reducing manufacture cost, reducing energy consumption and the like.
Description
Technical field
The utility model belongs to the filter press technical field, especially relates to a kind of filter press with reciprocal arm-tie shedding mechanism.
Background technology
The key device that filter press is the automatic discharging of full automatic pressure filter with reciprocal arm-tie shedding mechanism.The existing automatic reciprocating drawing-plate mechanism of filter plate, the general hydraulic motor that uses is controlled, on hydraulic system, tell collateral branch oil circuit control motor from total hydraulic circuit, the motor oil inlet and outlet is equipped with pressure switch, pressure switch is provided with certain safe pressure P(and is generally 6～7Mpa), and this pressure is lower than hydraulic system gross pressure P1(and is generally 15～20Mpa), but the pressure P 2(that is higher than the motor arm-tie is generally 4～6Mpa).When motor drive drag hook box arm-tie puts in place, the stall phenomenon can take place, this moment, motor pressure can rise to P by P2, and the pressure switch action returns to the control system signal and commutates.So, when pressure switch action undesired, when being lower than motor arm-tie pressure P 2 such as pressure setting P, the arm-tie i.e. situation of commutation not in place can appear, perhaps pressure is set P near hydraulic system gross pressure P1, still can not commutate when motor pressure is very high, can cause damage, influence service life motor and filter plate handle.
Summary of the invention
The purpose of this utility model is: avoid the technical problem of above-mentioned existence, provide a kind of commutation flexibly, the steady full-automatic drawing-plate mechanism of filter press reliably of even, the arm-tie of speed of actions.
The technical solution of the utility model is: comprise sprocket wheel, chain, drag hook box and power source, power source is a motor special, chain comprises arm-tie chain and first grade transmission chain bar, motor special is by first grade transmission chain band movable sprocket two, sprocket wheel two drives sprocket wheel three, and sprocket wheel three drives the arm-tie chain, and drag hook box and arm-tie chain link together, on the sprocket wheel two speed measuring device is housed, speed measuring device is connected with PLC.
Speed measuring device comprises tachometer disc that is installed on sprocket wheel two spindle noses and the switch that tests the speed that is installed on the switch bracket that tests the speed, and motor special is the torque type motor.
The beneficial effects of the utility model show: 1, be power source with the motor special, drive the reciprocating action of drag hook box by decelerator deceleration back, realize arm-tie, return, motor special adopts the torque type motor of making at this reciprocal arm-tie operating mode particular design, the drawing-plate mechanism of forming by this motor special at arm-tie, return in the process of commutation, but Fraquent start, it is low that the motor feels hot when commutating frequency height, continuous stall, and can be in operation of low-speed range long period or the work of longer-term stall, long service life, and noise is little.2, slow down by the two-stage chain drive, arm-tie moment increases, and the not in place or stall situation of arm-tie can not take place.3, detect arm-tie, return action by the switch that tests the speed, the control of PLC program realizes full-automatic arm-tie, returns the commutation action, saves equipment cost.4, compare with existing hydraulic motor arm-tie technology, energy-conservation obvious, power is reduced to the 1.5KW of motor special by 5.5～11KW of conventional hydraulic motors during arm-tie.The utlity model has advantages such as commutation is flexible, speed of actions is even, arm-tie is steadily reliable, design the control simplification, manufacturing cost greatly reduces, fault rate is low, cut down the consumption of energy.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a right view of the present utility model shown in Figure 1.
The specific embodiment
From structural representation of the present utility model shown in Figure 1 as can be seen, the utility model comprises motor special 4, sprocket wheel 1, sprocket wheel 29, sprocket wheel 3 10, sprocket wheel 41, arm-tie chain 2, first grade transmission chain bar 6, transmission bracket 8, between motor special 4 and the sprocket wheel 29 tensioning apparatus 7 is housed.Motor special 4 adopts the torque type motor of making at this reciprocal arm-tie operating mode particular design, have unique electrical characteristic and soft mechanical property, when load torque increases, can reduce rotating speed automatically and increase the output torque, can satisfy the permanent tension force of coiling work, constant linear velocity transmission needs.With the power source of motor special 4 as the arm-tie action, after the reductor deceleration, drive sprocket wheels 29 by sprocket wheel 1, first grade transmission chain bar 6, sprocket wheel 29 drives sprocket wheels 3 10, sprocket wheel 3 10 drives arm-tie chain 2 and sprocket wheel 41, and drag hook box 3 links together with arm-tie chain 2.Motor special 4 drives 3 reciprocating actions of drag hook box by secondary sprocket wheel deceleration transmission, realizes arm-tie, returns.
From right view shown in Figure 2 as can be seen, on sprocket wheel 29 spindle noses tachometer disc 13 is housed, the switch 12 that tests the speed is installed on the switch bracket 11 that tests the speed, and the switch 12 that tests the speed is connected with PLC.The operating state that the switch 12 that tests the speed detects arm-tie, returns by the commutation of PLC programme-control motor special 4, is realized arm-tie, the reciprocating action of returning, and functions such as the automatic warning of ultra-long time stall quits work are arranged.
