Abstract
The utility model is related to double screw extruder field more particularly to a kind of feeding protectors.A kind of double screw extruder feeding protector, including level-one storage bin, two level blanking bin, control of additive raw material device and low material level alarm are provided with the first level-sensing device in the level-one storage bin, the second level-sensing device are provided in the two level blanking bin；To level-one storage bin feed supplement when the control of additive raw material device receives the scarce material signal of the first level-sensing device, stopping signal is sent out to double screw extruder when the low material level alarm receives the scarce material signal of the first level-sensing device and the second level-sensing device simultaneously.The utility model double screw extruder feeding protector uses two level feed mode; and it is every grade of feed bin separate configurations level-sensing device; level-sensing device and feeding device and double screw extruder are linked; it realizes auto feed and lacks material and protect operation; reduce the labor intensity of labourer and the risk of error; simultaneously again can monitoring device operating status at any time, ensure that the integrality and production safety of formula.
Description
Technical field
The utility model is related to double screw extruder field more particularly to a kind of feeding protectors.
Background technology
It is produced for high yield large-scale twin-screw extruder, input material variety is more in the unit interval, weight is big and works
Intensity is big, especially the intensive work of dispensing link long-time when exist miscarry material risk, and convey various materials when
It waits, since the material discharge quantity of gravity different densities different-grain diameter is uneven, production is it is difficult to ensure that finished product material for a long time
The stability of property.Existing common storage bin is simple storing and feed supplement function, once level-sensing device damage is easy to happen object
Material walks empty situation, is not inconsistent standardization requirement, heavy then spiral shell when lacking a kind of material that the material of component is gently then produced in screw rod
Bar fast idle then equipment damage.
Invention content
The technical problem to be solved by the utility model is to provide a kind of double screw extruder feeding protector, the protections
Device uses two level feed mode, and is every grade of feed bin separate configurations level-sensing device, by level-sensing device and feeding device and double spiral shells
Bar extruder links, and realizes auto feed and lacks material and protect operation, that is, reduces the labor intensity of labourer and the risk of error,
Simultaneously again can monitoring device operating status at any time, ensure that the integrality and production safety of formula.
The utility model is realized in this way：A kind of double screw extruder feeding protector, including level-one storage bin, two
Grade blanking bin, control of additive raw material device and low material level alarm, are provided with the first level-sensing device in the level-one storage bin, under the two level
The second level-sensing device is provided in feed bin；The control of additive raw material device mends level-one storage bin when receiving the scarce material signal of the first level-sensing device
To double screw extruder when material, the low material level alarm receive the scarce material signal of the first level-sensing device and the second level-sensing device simultaneously
Send out stopping signal.
The discharge outlet in level-one storage bin is arranged in first level-sensing device.
The discharge outlet in two level blanking bin is arranged in second level-sensing device.
The volume of the two level blanking bin is less than level-one storage bin.
The utility model double screw extruder feeding protector uses two level feed mode, and is every grade of feed bin independence
It is configured with level-sensing device, level-sensing device and feeding device and double screw extruder are linked, auto feed is realized and lacks material and protect operation,
Reduce the labor intensity of labourer and the risk of error, at the same again can monitoring device operating status at any time, ensure that formula
Integrality and production safety.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model double screw extruder feeding protector.
In figure：1 level-one storage bin, 2 two level blanking bins, 3 control of additive raw material devices, 4 low material level alarms, 11 first material positions, 21
Second level-sensing device.
Specific implementation mode
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, in the content for having read the utility model statement
Later, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms equally fall within this Shen
It please the appended claims limited range.
Embodiment 1
As shown in Figure 1, a kind of double screw extruder feeding protector, including level-one storage bin 1, two level blanking bin 2, benefit
Expect controller 3 and low material level alarm 4, the first level-sensing device 11, the two level blanking bin 2 are provided in the level-one storage bin 1
Inside it is provided with the second level-sensing device 21；To level-one storage bin 1 when the control of additive raw material device 3 receives the scarce material signal of the first level-sensing device 11
To double spiral shells when feed supplement, the low material level alarm 4 receive the scarce material signal of the first level-sensing device 11 and the second level-sensing device 21 simultaneously
Bar extruder sends out stopping signal.In the present embodiment, preferably, the volume of the two level blanking bin 2 is less than level-one storing
Storehouse 1.
In the present embodiment, it is contemplated that going out in level-one storage bin 1 is arranged in the control to material position, first level-sensing device 11
At material mouth, the discharge outlet in two level blanking bin 2 is arranged in second level-sensing device 21.
When progress material is fed in production, in normal state, after the first level-sensing device 11, which is sent out, lacks material signal, feed supplement
The control of controller 3 starts charging (feeding) equipment and carries out feed supplement to level-one storage bin 1 or Manual material feeding mode is taken to supply material needed for production
Material.When low material level alarm 4 receives the scarce material signal of the first level-sensing device 11 and the second level-sensing device 21 simultaneously, low material position alarm
Device 4 controls double screw extruder and shuts down and alarm, can normal starting device after maintenance of equipment debugging.
