At present, it is to be completed by hydraulic driving oil cylinder under control system control that most cement grate-cooler is carried clinker, determine the grate arranged side by side of certain columns according to production capacity, and every row grate configures the driving oil cylinder of one or two parallel connection, every row grate is given and is driven oil cylinder fuel feeding by a 3-position 4-way Proportional valve, in order to control advancing and retreating of grate, every row grate has former and later two approach switch control displacements, in work, with 3-position 4-way Proportional valve spool travel, the aperture position of spool changes, the port size that the relative valve core opening of valve body is formed changes, thereby produce different flows and reach the fast adjusting of combing.Clinker mode of movement is the comb speed by setting, the spool enable possition of corresponding Proportional valve, drive the driving oil cylinder of each row grate that grate is advanced with the speed of setting simultaneously, after putting in place, the grate that multiple row grate arranged side by side is listed as with interval two successively retreats the mode of reset, grouping retreats repeatedly, is a stroke until all grates are all return original position.Problems of the prior art are: due to grate machining accuracy and assembly error, every row grate motion speed difference, in the time that startup moves ahead, each row grate can not be advanced and put in place simultaneously, just can carry out back operation owing to will waiting each row grate all to advance and putting in place, therefore grate in service because of latency delays the time, affect grate overall operation speed, reduce clinker transfer efficiency.
Model utility content
Main purpose of the present utility model is for the problems referred to above, provides a kind of cement grate-cooler that makes multiple row grate advanced in unison to drive oil cylinder hydraulic device, reaches and improves grate overall operation speed, reduces the effect of clinker transfer efficiency.
The utility model solves the technological scheme that its technical problem adopts:
A kind of grate-cooler that makes multiple row grate advanced in unison drives oil cylinder hydraulic device, comprise one or two parallel drive oil cylinder being connected in respectively in multiple row grate, it is characterized in that described each driving oil path in oil cylinder connects respectively two four-way Proportional valves with A, B, P, T hydraulic fluid port, described A, B hydraulic fluid port connect respectively rod chamber and the rodless cavity of described driving oil cylinder, and T hydraulic fluid port connects fuel tank, P hydraulic fluid port Bonding pressure oil sources; Also be provided with a gear shunting motor, the filler opening of described gear shunting motor is connected to pressure oil-source by A1 hydraulic fluid port, the P1 hydraulic fluid port of a 2/2-way Proportional valve, the rod chamber that respectively distributes hydraulic fluid port and be connected to via the one-way valve of a correspondence respectively each driving oil cylinder of gear shunting motor.
The beneficial effects of the utility model are: owing to having adopted gear shunting motor, before making fluid drive cylinder piston rod with volume shunting accurately, push away, therefore can make multiple row grate advanced in unison, thus, can eliminate in prior art because of the asynchronous latency delays time of causing, thereby improve grate-cooler motion speed, promote clinker transfer efficiency.In addition, in the utility model, adopt two four-way Proportional valves to replace the 3-position 4-way Proportional valve using in prior art, simplified hydraulic system element, reduce proportional valve control element, make apparatus structure simple, reduce rate of fault.
Brief description of the drawings
Fig. 1 is structure of the present utility model and hydraulic schematic diagram.
In figure: 1 gear shunting motor, 21-25 one-way valve, 31-35 grate, 41-45 drives oil cylinder, 5 2/2-way Proportional valves, two four-way Proportional valves of 61-65,7 fuel tanks, 8 pressure oil-sources.
Below in conjunction with drawings and Examples, the utility model is described in detail.
Embodiment
Fig. 1 illustrates that a kind of grate-cooler that makes multiple row grate advanced in unison drives oil cylinder hydraulic device, comprise one or two parallel drive oil cylinder being connected in respectively in multiple row grate, in the present embodiment, comprise the each driving oil cylinder 41-45 being connected in respectively on 5 row grate 31-35.Of the present utility modelly be characterised in that described each driving oil path in oil cylinder connects respectively two four-way Proportional valve 61-65 with A, B, P, T hydraulic fluid port, described A, B hydraulic fluid port connect respectively rod chamber and the rodless cavity of described driving oil cylinder, and T hydraulic fluid port connects fuel tank 7, P hydraulic fluid port Bonding pressure oil sources 8; In this hydraulic pressure installation, be also provided with a gear shunting motor 1, the filler opening of gear shunting motor 1 is connected to pressure oil-source 7 by A1 hydraulic fluid port, the P1 hydraulic fluid port of a 2/2-way Proportional valve 5, the rod chamber that respectively distributes hydraulic fluid port and be connected to via the one-way valve 21-25 of a correspondence respectively each driving oil cylinder 41-45 of gear shunting motor.Said gear diffluence motor has adopted U.S. DELTAPOWER gear shunting motor.
Working procedure of the present utility model and principle:
When the work of cement grate-cooler, under control system control, first, grate 31-35 advances, 2/2-way Proportional valve 5 moves at electromagnet DT6 effect lower valve core, A, P hydraulic fluid port is connected, pressure oil is through P, A hydraulic fluid port enters gear shunting motor 1, through shunting, enter respectively the rod chamber that drives oil cylinder 41-45 by corresponding one-way valve 21-25 through each shunting oil export, drive cylinder piston rod to advance with volume shunting accurately, thereby promoting grate 31-35 advanced in unison puts in place, now, two four-way Proportional valve 61-65 are respectively under the effect of electromagnet DT1-DT5, spool moves, B, T hydraulic fluid port is connected, A, P hydraulic fluid port is obstructed, each oil cylinder rodless cavity fluid that drives is respectively through B, T hydraulic fluid port is got back to fuel tank 7, then, grate retreats, and the grate that 5 row grates arranged side by side are listed as with interval two successively retreats the mode of reset, and grouping retreats 3 times, is a stroke until 5 row grates are all return original position.Now, under the effect of electromagnet DT1-DT5, spool moves, the A of two four-way Proportional valve 61-65, T hydraulic fluid port, B, P hydraulic fluid port is connected, when operation, the 1st time: grate 31, 34 retreat, pressure oil is respectively through two four-way Proportional valves 61, 64 P, B hydraulic fluid port enters corresponding driving oil cylinder 41, 44 rodless cavity, driving cylinder piston rod retreats, thereby grate 31, 34 retreat, now, because one-way valve only allows fluid one-way flow, therefore fluid can not enter gear shunting motor 1, drive oil cylinder 41, 44 rod chamber fluid are through the A of two four-way Proportional valves, T hydraulic fluid port is got back to fuel tank 7, the 2nd time, grate 32,35 retreats, and the 3rd time, grate 35 retreats, and its working procedure is all with the 1st back operation.So far complete a stroke.
Can be found out by the above, owing to having adopted gear shunting motor, fluid is advanced with the shunting of volume accurately piston rod, therefore can make 5 row grate advanced in unison, thus, can eliminate in prior art because of the asynchronous latency delays time of causing, thereby improve grate-cooler motion speed, promote clinker transfer efficiency.In addition, in the utility model, adopt two four-way Proportional valves to replace the 3-position 4-way Proportional valve using in prior art, simplified hydraulic system element, reduce proportional valve control element, make apparatus structure simple, reduce rate of fault.
The above, be only preferred embodiment of the present utility model, not structure of the present utility model done to any pro forma restriction.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
