Description
Technical field]
Industrial automation is the utility model is related to, it is more particularly to a kind of to be used for nitrogen-phosphorus-potassium compound fertilizer raw materials for production dispensing
The solid material weigher of process.
Background technology]
, it is necessary to accurately be measured to solid powders such as potassium chloride, monoammonium phosphate in the production of nitrogen-phosphorus-potassium compound fertilizer,
Will by various raw material weighings, mixing work be stirred subsequently into mixer for quality as defined in formula in a short time during production
Sequence, by manpower it is difficult to accomplish it is quick, accurate.The metering method generally used at present is using belt conveyer scale, uclear scale, spiral metering
Scale etc. is measured, and the mode of wherein belt conveyer scale is the most universal.But the hydrogen chloride gas and air produced in process of production
In moisture combine generate hydrochloric acid, at the same time, generate substantial amounts of raw material dust, these dust and hydrochloric acid pair in production
The rotary part of metering outfit generates corrosion, raises the failure rate of machine, and seriously affected the metering of metering outfit
Precision.And since solid particle is not of uniform size, requirement of weighing is different, for the high measuring apparatus of precision, using it is long can shadow
Sound arrives accuracy, so, a kind of in such a case, high there is an urgent need to measuring accuracy, long-lived measuring equipment.
The content of the invention]
High, the long-lived solid material weigher the technical problem to be solved by the present invention is to provide a kind of precision.
Technical solution is as follows：
A kind of solid material metering device of automatic tipping bucket, including feed section, metering section；
Further, feed section, the top in metering section, including motor, feed bin, feed auger, motor is with supplying
Material auger is connected, and has a discharge port in auger end；
Further, metering section, in feed section in the following, including scale hooper, weighing frame；Weigh on frame equipped with deceleration
Motor and scale hooper, decelerating motor drive scale hooper upset, weigh and are weighed below frame equipped with weighing sensor weighing frame, are weighed
Connection weight body, weight body are in metering section lower part below sensor.
Further, the metering section further includes PLC controller and integrating instrument, PLC controller connection weighing sensor,
The motor and decelerating motor of feed section, after the completion of weighing, scale hooper automatic turning is controlled by PLC controller.
Further, weighing sensor quantity is 3.
Further, scale hooper is connected with gear reducer, position sensor in reducing motor output shaft.
The beneficial effects of the utility model are：The solid material metering device of automatic tipping bucket during batch weighing due to belonging to
Static weighing, so measuring accuracy is high, rotary part is few, and failure rate is extremely low, and the utility model is simple in structure, easy to use, is
Integrated cost of uniting is relatively low.
Brief description of the drawings]
Fig. 1 is the structure diagram of solid material weigher of the present invention.
Fig. 2 is the schematic diagram of the blind controller system of solid material weigher of the present invention.
1 motor, 2 augers, 3 feed bins, 4 scale hoopers, 5 position sensors, 6 weigh frame, and 7 weighing sensors, 8 weight bodies, 9 use
Expect transmission belt, 10 sensor fastening devices, 11 decelerating motors.
Embodiment]
In order to make the technological means that the utility model is realized clear, it is new that this practicality is expanded on further below in conjunction with the accompanying drawings
Type.
As shown in Figure 1, structure such as Fig. 1 of solid material weigher of the embodiment of the present invention, including feed section, measurement unit
Point；
Feed section, the top in metering section, including motor 1, feed bin 3, feed auger 2, motor 1 and feed auger
2 are connected, and have a discharge port in 2 end of auger；
Metering section, between feed section and materials transmission belt 9, including scale hooper 4, weighing frame 6；Weigh frame 6
Upper to drive scale hooper 4 to overturn equipped with decelerating motor 11, position sensor 5 on 11 output shaft of decelerating motor, weighs the lower section of frame 6 and sets
There are 7 weighing frame of weighing sensor and the decelerating motor 11 installed thereon and the overall weighing of scale hooper 4, weighing sensor 7 has solid
Determine device 10, the lower section of weighing sensor 7 connection weight body 8, weight body 8 is in metering section lower part；It is below metering section
Materials transmission belt 9,7 quantity of weighing sensor are 3.
As shown in Fig. 2, metering section further includes PLC controller and integrating instrument, PLC controller connection weighing sensor 7, supply
Expect the motor 1 and decelerating motor 11 of part, PLC controller is connected with integrating instrument.
Scale hooper 4 is connected directly with decelerating motor 11, position sensor on 11 output shaft of decelerating motor.
The course of work of solid material weigher is as follows：After weigher starts, PLC passes through 11 output shaft of decelerating motor first
On position sensor detection device 5, detection scale hooper 4 whether in place, not in accurate location, decelerating motor 11 is driven to just
True position, hereafter, feed auger 2 rotates at full speed to be started to be fed, when reaching close to the first object value of the setting of scale hooper 4,
Feed auger 2 reduces speed now, and starts to be fed at a slow speed, when reaching final goal value.Feed auger 2 stalls, and stops feed.Metering
The control energizing signal that the wait of bucket 4 PLC is sent, this signal is controlled by production technology dispensing signal, such as 4~20mA of electromagnetic flowmeter
Current signal, when reaching the cumulant of needs by batch integrating, decelerating motor 11 drives scale hooper 4 to overturn.With weighing hopper 4
Upset, material poured on following belt conveyor.Finally, rotated back into by position-detection sensor 5, PLC control scale hoopers 4
Predetermined position.Feed auger 2 is fed to scale hooper 4 again, carries out next circulation.
The present apparatus is also added into perfect alarm, is detected and controlled by PLC controller, there is auger fracture report
Alert, auger stall alarm, integrating signal to condition is alarmed, upset delayed alarm etc..
Above description is merely a prefered embodiment of the utility model, on the scope of protection of the utility model is not limited in
Embodiment is stated, for a person skilled in the art, what is carried out on the premise of the principle of the present invention is not departed from some changes
Into these improvement also should be regarded as the scope of protection of the utility model.
