Description
Technical field
The present invention is about a kind of energy-saving structure of ceramic brick press.
Background technology
Ceramic industry is a big power consumer, yet the electricity charge have accounted for suitable ratio on production cost, and along with energy problem comes into one's own day by day, the saving energy becomes and more and more payes attention to.Pottery enterprise has carried out a large amount of reducing energy consumption engineerings (as ball mill, plunger displacement pump aspect energy-saving and cost-reducing for this reason, kiln etc.), now have energy-conservation this piece of ceramic brick press scheme that always could not be well solved only, my company develops brick machine frequency conversion oil electric energy-saving system specially for this reason.The technical process of brick machine is generally divided into several stages such as filler, matched moulds, locked mode, punching press (being divided into punching press two times punch one time) rapping, die sinking, taking-up, and each stage needs different pressure and flow.For oil pump motor, the load of each course of action of brick machine is always in variable condition, in the hydraulic system of constant displacement pump, oil pump motor provides constant flow with constant rotating speed, unnecessary hydraulic oil refluxes by overflow valve, this process is called high pressure throttling, and the energy loss being caused by high pressure throttling is according to statistics up to 36%-68%.At variable pump, also have same problem equally, just its energy loss is less by 10% than constant displacement pump.
Main power-saving technology is frequency conversion control energy-saving technology at present, due to frequency conversion control energy-saving in the precision of improved stabilization of equipment performance, finished product, boost productivity on and on energy-saving efficiency, all compared with original system, have more advantage, so frequency conversion control energy-saving transformation has become the first-selection of press reducing energy consumption.
Summary of the invention
The present invention object be to solve the large problem of the long-standing power consumption of ceramic industry brick machine.
The technology used in the present invention means are as described below.
A kind of ceramic brick press proportion control energy-saving structure, it comprises main motor, oil pump and brick machine, main motor connects oil pump, oil pump connects brick machine, and main motor drives oil pump, and oil pump provides the work of hydraulic-driven brick machine to brick machine, also be provided with proportional control apparatus, sync detection device and pressure-detecting device, brick machine Bonding pressure checkout gear, pressure-detecting device connects proportional control apparatus, and proportional control apparatus connects main motor; Main motor connects proportional control apparatus by sync detection device.
This proportional control apparatus connects man-machine interface.
This proportional control apparatus is frequency-variable controller.
Beneficial effect of the present invention is as described below.
1, can frequency-variable controller device be installed at original brick machine and enter transformation, when frequency-variable controller and main machine operation, its pressure response time is only 0.1 second, the flow response time is only 0.03 second, the product of producing is more accurate, and board work is more stable, and fraction defective reduces greatly.
2, adopt pressure, flow double-close-loop FEEDBACK CONTROL, during board work, need great pressure and flow, frequency-changing control system just provides great pressure and flow, and the electric current of main motor also can convert along with the demand of system, reduced energy loss, and can arrange by human-computer interaction interface.
3, when press filler, picking, etc. during operating mode attonity, main motor stops operating, generation current, does not reach energy-conservation object thereby system does not consume any energy.
4, energy-conservation: the brick machine that adopts frequency-changing control system, system pressure, flow adopt two closed loops, when brick machine is during in operating mode attonitys such as filler, pickings, can oil circuit control pipe ends valve closing, pipeline is interior in there being the state of pressure, when needs are beaten brick, open, reduce oil mass and supplement the pipeline time.Hydraulic system is carried out fuel feeding according to the flow of actual needs and pressure, overcome the high energy consumption that the high pressurized overflow of common Constant Pump System produces, at main motors of high flow capacity working stage such as die sinking, matched moulds, punching presses according to the rotary speed working of setting, at low discharge working stages such as filler, pickings, reduced main motor speed, actual consumption reduces 25%--45%.
5, rapidly, production efficiency is high in response: frequency-changing control system fast response time, and pressure rise time and flow rise time, soon to 30ms, have been improved the response speed of hydraulic system, have reduced action conversion time, have accelerated the operation beat of complete machine; When hydraulic system of press moves automatically, when having valve open, system pressure can decline moment, and frequency-changing control system can, at 30ms with the interior oil mass of supplementing rapidly, recover pressure to setting value.
6, pressure stability is accurate: frequency-changing control system regulating power is strong, and pressure closed loop control model makes system pressure highly stable, and pressure wave momentum, lower than ± 0.5bar, has improved the Forming Quality of product.
7, oil temperature temperature rise is low: brick machine work is risen 8 ℃-10 ℃ by starting shooting to entering stable state oil temperature, and at 35 ℃ of room temperatures, without cooling water, the consumption of cooler also greatly reduces, and has extended complete machine life-span of hydraulic oil, hydraulic pressure consumable accessory (as oil sealing) particularly.
The beneficial effect of patent of the present invention is: 1, power saving rate can reach more than 25%; 2, rapidly, production efficiency is high in response; 3, pressure stability is accurate; 4, oil temperature temperature rise is low.
Accompanying drawing explanation
Fig. 1 is structured flowchart of the present invention.
The specific embodiment
A kind of ceramic brick press proportion control of Fig. 1 the present invention energy-saving structure, it comprises main motor 1, oil pump 2 and brick machine 3, main motor 1 connects oil pump 2, oil pump 2 connects brick machine 3, main motor 1 drives oil pump 2, oil pump 2 provides hydraulic-driven to press brick 3 machine work to brick machine 3, it focuses on, the present invention is also provided with proportional control apparatus 4, sync detection device 5 and pressure-detecting device 6, brick machine 3 Bonding pressure checkout gears 6, pressure-detecting device 6 connects proportional control apparatus 4, and proportional control apparatus 4 connects main motor 1; Main motor 1 connects proportional control apparatus 4 by sync detection device 5.
Specific works process is: by proportional control apparatus, sent the given instruction of pressure and flow, the instruction that main motor provides according to proportional control apparatus, with given speed drive oil pump, is given and pressed brick to provide hydraulic pressure to drive brick machine to work by oil pump.When pressure meets job requirement the main motor of needs does not continue to provide power again, pressure-detecting device provides and feeds back signal to proportional control apparatus, and proportional control apparatus is controlled main motor and stopped the rotation, motor rotation while working, during inoperative, motor stops the rotation, thereby reaches the object of saving electric energy.Same, when pressure-detecting device, pressure to be detected inadequate, in the time of need to starting main machine operation, also can control immediately main electric motor starting.
