Abstract
The utility model discloses a spiral oil press capable of automatically controlling the pressure of a squeezing chamber, and solves the problems of inconvenient operation, poor precision and unstable pressure caused by manually adjusting the pressure of the squeezing chamber of the existing spiral oil press. The technical scheme is that the spiral oil press comprises a main motor connected a squeezing screw spindle in the squeezing chamber by a driving mechanism, and a feeding motor connected with the feeding mechanism; and the main motor is formed by connecting a main motor current meter, a PLC (programmed logic controller), a feeding motor frequency converter and a feeding motor in sequence. The spiral oil press capable of automatically controlling the pressure of the squeezing chamber is simple in structure, simple and convenient to control, timesaving, laborsaving and capable of ensuring the stable pressure of the squeezing chamber when the spiral oil press operates.
Description
Technical field
The utility model relates to a kind of screw oil expeller, and the screw oil expeller of gun pressure power is pressed in a kind of automatic control specifically.
Background technology
At present in oil extraction by pressing technology, the quality of its key equipment screw oil expeller work effect has close relationship with going into to press to expect temperature, moisture content and press for extracting juice gun pressure power, when rotating speed one timing of pressing the spiral shell main shaft, go into to press the material temperature, moisture content can be regulated by the digester (-tor) in this operation, and the size of pressing gun pressure power is being pressed under the given situation of thorax compression ratio, and is then relevant with the size of pressing the thorax inlet amount.The big I of press for extracting juice gun pressure power reflects that by the size of current of the main motor of screw oil expeller therefore, reasonably inlet amount can make screw oil expeller reach desirable squeezing effect when work.But the screw oil expeller inlet amount of using in the course of the work all is by the main current of electric size variation of operator according to screw oil expeller at present, the rotating speed of the moving control of armrest feeding motor is finished, its shortcoming is that the manually operated precision of operator is low, have under the situation of fluctuation at screw oil expeller main frame electric current, can not regulate it exactly and press what of thorax inlet amount, being difficult to make the press for extracting juice gun pressure to try hard to keep to keep steady decides, or press for extracting juice thorax inlet amount is too small, cause pressing the thorax hypotony and can not get desirable squeezing effect, or the increase of press for extracting juice thorax inlet amount is too fast, causes pressing the instantaneous rising of gun pressure power and causes the badly damaged of screw oil expeller.In addition, notice must high concentration when the manual operation for the operator, has so also increased operator's labour intensity greatly.
Summary of the invention
The purpose of this utility model is in order to solve the problems of the technologies described above, provide a kind of simple in structure, control is easy, time saving and energy saving, can guarantee to press the stable automatic control of gun pressure power during the screw oil expeller operation presses the screw oil expeller of gun pressure power.
Technical scheme comprises the main motor that is connected with press for extracting juice spiral shell main shaft in pressing thorax through driving mechanism and the feeding motor that is connected with feeding mechanism, and described main motor connects composition with main galvanometer motor, PLC controller, feeding motor frequency converter and feeding motor successively.
Described main galvanometer motor is the digital display ammeter.
Be provided with one or the parallel press for extracting juice spiral shell main shaft more than two or two of center line in the described press for extracting juice thorax.
Described feeding mechanism is scroll feeder or is the digester (-tor) feeder.
The utility model is adopted the signal that can reflect the main current of electric that presses breech pressure and is sent the PLC controller to by ammeter, compare with value range default in the PLC controller, and convert comparative result to control signal and be defeated by the feeding motor frequency converter, thereby change the feeding motor rotating speed, and then the control screw oil expeller presses the size of thorax inlet amount, the final stable automatic control process of press for extracting juice gun pressure power of realizing.The utility model has fundamentally substituted past manual operation control and has pressed gun pressure power process, realizes automation control, have simple in structure, control is easy, province's amount is laborsaving, press the stable advantage of breech pressure during the screw oil expeller operation.
Description of drawings
Fig. 1 is the utility model schematic diagram.
Wherein, 1-master's motor, 2-driving mechanism, 3-feeding motor, 4-feeding mechanism, 5-press thorax, 6-master's motor digital display ammeter, 7-PLC controller, 8-feeding motor frequency converter.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further explained explanation:
Main motor 1 is connected with press for extracting juice spiral shell main shaft in pressing thorax 5 through driving mechanism 2, is used for driving pressing the spiral shell main shaft and rotating, and feeding motor 3 connects feeding mechanisms 4, is used for driving feeding mechanism 4 to the interior inlet amount of press for extracting juice thorax 5.Described main motor 1 also connects with main motor digital display ammeter 6, PLC controller 7, feeding motor frequency converter 8 and feeding motor 3 successively.Press for extracting juice spiral shell main shafts in the described press for extracting juice thorax 5 can be installed more than one or one as required, are more than 2 or 2 the time when pressing the spiral shell main shaft, and its center line is answered keeping parallelism.Described feeding mechanism 4 can or be the digester (-tor) feeder for scroll feeder.
Operation principle:
During work, going into to press material (claiming to press material again) sends in the press for extracting juice thorax 5 of screw oil expeller through the feeding mechanism 4 that feeding motor 3 drives, the screw spindle of main motor 1 in the press for extracting juice thorax 5 that driving mechanism 2 drives rotates, push ahead and press material and push squeezing to pressing material, the big I of pressure that the extruding squeezing produces is reflected by main motor 1 size of current, and show at digital display ammeter 6, this current signal is sent to PLC controller 7, after PLC controller 7 reads main motor current signal, the predetermined range value that sets in advance with it compares, obtain a comparative result, and export corresponding control signal according to comparative result, namely convert frequency signal to and feed back to feeding motor frequency converter 8, and the rotating speed of change feeding mechanism motor 3, and then change feeding mechanism 3 to pressing the feeding amount of pressing material in the thorax 5, change the purpose of pressing thorax 5 pressure sizes to reach.When the current value of main motor 1 was excessive, gun pressure power height was pressed in expression, and PLC controller 7 control feeding motor frequency converters 8 reduce the rotating speed of feeding motor 3, to reduce to the feeding capacity that presses in the thorax 5; When the current value of main motor 1 was too small, expression press for extracting juice gun pressure power was low, and PLC controller 7 control feeding motor frequency converters 8 will improve feeding motor 3 rotating speeds, increase to the feeding capacity that presses in the thorax 5.Therefore, when the press for extracting juice thorax compression ratio of screw oil expeller remained unchanged, the utility model can be realized pressing the automatic control of gun pressure power in the screw oil expeller and stablizing, and reaches desirable squeezing effect.
