Description

The oil press automaton
The utility model relates to a kind of grease and produces industrial middle cotton seed oil mill automaton.
At present, in cottonseed oil expression industry, exist mechanical expression method and two kinds of method for producing oil of lixiviation process.Mechanical expression legal system oil is good because of its smell, eating mouth feel and color and luster, and the finished product well cuts is few and welcome by consumers in general, so this method is produced the main production method that is still in China's oil prodution industry.But because manually-operated is adopted in oil press charging at present, not only labour intensity is big, the healthy of harm workman works long hours, but also can bring following unfavorable factor: the one, because depending on workman's experience, technical merit and sense of responsibility etc., feed operation make charging unbalanced, sometimes the sharp increase of material base amount makes that pressing the cage internal pressure increases suddenly in the unit volume, it is excessive to press the spiral shell load, causes the oil press main shaft to twist off when serious and the excessive catastrophe failure such as burn out of main motor load.The 2nd, owing to go into to press the material temperature without preferred control, thereby low when high during oil yield, blob of slag residual oil content has had a strong impact on economic benefit of enterprises up to 5%--8% sometimes.
The utility model purpose provides a kind of material temperature control (the cottonseed oil yield of this temperature range is the highest) within the specific limits of can be automatically will going into to press, and can stop the oil press automaton that feed also can recover normal feed automatically when pressing the cage internal pressure automatically when too high.
The purpose of this utility model is achieved in that it adopts independently electromagnetic braking motor to drive the charging of vertical shaft screw impeller by mechanical reduction gear; Electrical appliance part is by switch TA, QA, relay C 1, C 2, C 3, time-delay relay SJ, overcurrent relay GL, temperature controller WK, alarm Y, resistance R r and induction coil L form, its annexation is:
A, from electromagnetic braking motor D 2Three-phase power line in arbitrary phase line insert switch TA, QA--C 1Coil one resistance R r, take back D then 2Three-phase power line in another phase line in, wherein on the QA switch C is arranged 1Auxiliary normally open contact C 1--3Locking;
With C 1The circuit of coils from parallel connection of coils has: C 1Often open main contact C 1-1--C 3Normally closed interlock--GL normally closed interlock--C 2Coil wherein also is parallel with the SJ normally open contact on the GL normally closed interlock;
With C 1The circuit of coils from parallel connection of coils also has: C 2Auxiliary normally closed interlock C 2--2-SJ coil;
With C 1The circuit of coils from parallel connection of coils also has: temperature controller WK--alarm Y--C 3Coil;
B, electromagnetic braking motor D 2Three-phase power line pass through C respectively 2Three often open main contact C 2--1After connect D again 2
C, in main motor D 1Power line on induction coil L is housed, L takes at two ends current relay GL, meets simultaneously also C 1Auxiliary normally closed interlock C 1-2
The utlity model has following advantage and good effect: 1) oil yield is high and stable.Be strict controlled in optimum range owing to go into to press the material temperature, make the cottonseed oil yield reach the highest and very stable.2) can in time avoid having ensured the trouble free service of oil press owing to press too high machinery that causes of cage internal pressure and apparatus failure.3) alleviate labor strength greatly, improved work situation.It both can be used to transform existing oil equipment, also can be used for new oil equipment, and it is simple in structure, with low cost, installation is easy, easy to use.
After this self-con-tained unit has been installed in contrast, process cottonseed every day and bring up to 22.5 tons, 30 kilowatt hours of economizing on electricity by 16.5 tons; The cottonseed cake residual oil content drops to 5-5.8% by original 5.8-7.5%, on average reduces about 1.2%.As calculating by falling 1%, every oil press is produced 14 tons of cottonseed cakes daily, can increase production 140 kilograms of greases, by 9 yuan of/kilogram calculation of price. and 1260 yuan of day increase benefits, every oil press (200 type) only reduces by one of residual cake oil yield, can increase benefit 38700 yuan in every month.
Elaborate below in conjunction with accompanying drawing;
Fig. 1 the utility model frame for movement schematic diagram
Fig. 2 the utility model electrical schematic diagram
Referring to Fig. 1, mechanical part of the present utility model is by electromagnetic braking motor 1, device 6 and mechanical reduction gear were formed when the vertical shaft spiral pushed away.Mechanical reduction gear is by I group sprocket wheel 2, pot wheel pot bar 3, and II group sprocket wheel 4 and conical gear group 5 are formed.Remainder is existing oil press essential structure among the figure, main motor 13 drives belt pulley set 12, press spiral shell 8 rotations through bevel gear set 11, straight-tooth wheels 10, drive, 9 for pressing cage, the 7th, hopper, the cottonseed material enters press for extracting juice cage 9 through hopper 7 under the promotion of vertical shaft spiral propeller 6, expressed oil comes under the propelling extruding of pressing spiral shell 8.
Referring to Fig. 2, electrical appliance part basic principle of the present utility model is, utilize induction coil L to obtain the main motor signal of telecommunication and connect overcurrent relay GL coil, in the normally closed interlock Access Control circuit of GL, the normally open contact that is parallel with SJ with the GL normally closed interlock is eliminated the back for overcurrent and is recovered D 3Running.Be connected to temperature controller WK and alarm Y in control circuit, the sensor of temperature controller is installed in the discharging opening place of cottonseed frying pan, goes into to press the material temperature with monitoring, when being higher or lower than set point of temperature, cuts off control circuit automatically, and simultaneously, alarm Y reports to the police, D 3Outage stops operating, and feed stops, and treats the recovery automatically of the normal back of temperature.Concrete electrical signal transfer process is:
State 1: start D 1, press QA, the cage internal pressure is normal when pressing, D 1No over-current phenomenon avoidance goes into to press the material temperature also just often: C 1Coil electricity → C 1--1Closure → C 2Coil electricity → C 2--1Closure → D 2Running; At this moment normal feed.Simultaneously, C 1--3Locking: C 1--2Open, GL brings into play supervisory function bit; C 2--2Disconnect SJ coil no current.
State 2: press the cage internal pressure and increase D 1Excess load causes overcurrent, GL normally closed interlock disconnection → C 2Coil blackout → C 2--1Disconnection → D 2Stall stops feed; Simultaneously, C 2--2Closure → SJ coil electricity → SJ normally open contact closure → C after delaying time 2Coil is switched on → C again 2-1Closure → D again 2Recover running, again feed; At this moment D 1Do not had over-current phenomenon avoidance, oil press is working properly.
State 3: when going into to press material temperature overshoot value (too high or too low): WK connection → C 3Coil electricity → C 3Normally closed interlock disconnection → (C 2Coil blackout → C 2--1Disconnection → D 2Stall stops feed; Meanwhile, alarm Y reports to the police.After going into to press the recovery normally of material temperature, WK disconnection → C 3Coil blackout → C 3Normally closed interlock closure → C 2Coil electricity → C 2--1Closure → D 2Recover running, feed again, oil press operate as normal.
