Background technology
In coal preparation, adopting dense-medium separation is one of the most frequently used mode.At present, the medium that washery interpolation coal separation is used mainly adopts forklift or grab bucket that coal separation medium is dropped in medium pool, also the employing having manually adds coal separation medium, adding the low and operating personal of efficiency only adds with the experience of self, the amount of the coal separation medium adding also can only be estimated, can accurately not calculate the total amount of adding coal separation medium.When interpolation coal separation medium is on the low side, affect the effect of coal separation processing, interpolation coal separation medium can cause the waste to coal separation medium again when too many.
Therefore, be necessary to design a kind of can be convenient, fast and accurate for adding the dosing device of coal separation medium, guarantee each appropriate coal separation medium that adds, the effect that guarantees coal separation processing is avoided the waste of coal separation medium simultaneously.
Utility model content
In view of this, the purpose of this utility model be to provide a kind of can be convenient, fast, prepare to add the dosing device of coal separation medium.
In order to solve the problems of the technologies described above, a kind of dosing device that the utility model provides, comprise hopper, feeding cylinder and actuating device, described feeding cylinder is horizontally disposed with, and the top of described feeding cylinder one end is connected with described hopper, the bottom of the described feeding cylinder other end is provided with discharging opening, be also provided with for transmitting the screw rod of material, and described screw rod is connected with described actuating device in the cylinder of described feeding cylinder.
Further, described actuating device comprises motor and the control setup being connected with described motor, and described control setup is provided with driving switch, read-out and the annunciator for controlling described machine operation, and the rotating shaft of described motor is connected with the rotating shaft of described screw rod.
Further, described hopper is provided with for measuring the position transduser of the height of described material in hopper, and described position transduser is connected with described control setup
Further, also comprise that one for supporting the support of described hopper, described hopper is positioned on described support.
Adopt technique scheme to there is following beneficial effect:
A kind of dosing device that the utility model provides, owing to being provided with the screw rod of feeding in feeding cylinder, actuating device drives screw rod to pass on, and then the material promoting in feeding cylinder moves to discharging opening.Set the rotating speed of screw rod, can calculate discharging opening in the unit time and fall the total amount of material, thereby can facilitate and realize exactly the quantitative interpolation of material.
Accompanying drawing explanation
Fig. 1 is dosing device structural representation in the utility model one embodiment.
Reference numeral synopsis:
1---feeding cylinder; 2---hopper; 3---support;
4---control setup; 5---position transduser; 6---motor;
11---screw rod; 12---discharging opening; 41---read-out;

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in Figure 1, the dosing device that the utility model provides, comprise hopper 2, feeding cylinder 1 and actuating device, feeding cylinder 1 is horizontally disposed with, and the top of feeding cylinder 1 one end is connected with hopper 2, the bottom of feeding cylinder 1 other end is provided with discharging opening 12, be also provided with for transmitting the screw rod 11 of material, and screw rod 11 is connected with described actuating device in the cylinder of feeding cylinder 1.During specific works, material enters in feeding cylinder 1 from the bottom of hopper 2, opens actuating device, the rotation of drive screw 11, thus make screw rod 11 drive the other end to feeding cylinder 2 of the material in feeding cylinder 1 to move, finally from discharging opening 12, fall.Wherein, Fig. 1 has carried out local analysing and observe to feeding cylinder 1, to demonstrate the structure of the screw rod 11 of feeding cylinder 1 inside.According to the pitch size of screw rod 11 and the rotating speed of screw rod, can calculate the inventory that unit time inner screw 11 transmits in feeding cylinder 1, thus final definite total amount adding materials.Wherein, the rotating speed of screw rod 1 can be set by actuating device, and the time of concrete feeding can have manual measurement to determine, the time that a clock counter is measured feeding automatically also can be set.When material reaches wanted predetermined set interpolation value, close actuating device, can stop the interpolation of material, thereby realize the quantitative adding purpose of material.The dosing device that the utility model provides adds man-hour for coal separation, adds coal separation medium in hopper 2, the discharging opening of feeding cylinder 1 12 is arranged in to the media slot of coal separation medium, can realize the object that coal separation medium is quantitatively added.When repeatedly adding coal separation medium, the amount of at every turn adding is added and can obtains overall addition, thereby realize the object of accurately adding coal separation medium total amount.
Above-mentioned actuating device comprises motor 6 and the control setup 4 being connected with motor 6, and control setup 4 is provided with for controlling driving switch 42, read-out 41 and the annunciator 43 of motor 6 work, and the rotating shaft of motor 6 is connected with the rotating shaft of screw rod 11.Motor 6 drives screw rod 11 to rotate, and realizes the transmission to material in feeding cylinder 2.Driving switch 42 can be controlled the operation of motor 6 and stop.According to predefined rotating speed, calculating the material total amount transmitting in the unit time can show timely in read-out 41.Read-out 41 can also show the rotating speed of screw rod 11 and the time of operation simultaneously, so that the situation of operating personal grasp equipment operation in time.Above-mentioned siren horn 43 is for sounding the alarm to some emergency casies, so that operating personal is processed in time.While being finished as hopper 2 materials, siren horn 43 can give the alarm, and alert adds materials in time.
Above-mentioned hopper 2 is provided with for measuring the position transduser 5 of the height of hopper 2 materials, and position transduser 5 is connected with control setup 2.Position transduser 5 can detect the situation of material in hopper 2 in time, when in hopper 2, material is lower than certain value, when only having 10cm apart from the bottom of hopper 2, position transduser is sent to the signal of detection in control setup 4, siren horn by control setup 4 sounds the alarm and reminds operating personal in hopper 2, to add materials in time, guarantee the abundance of material in hopper 2, thereby avoid the empty material of appearance in feeding cylinder 1, and then the empty material of screw rod 11 transmission, and the final calculating that affects the total amount that adds materials.Can certainly design the device of an automatic charging, when importing the detection signal of position transduser 5 into control setup 4, transmission is to automatic charging device, automatic charging device is added materials in trend hopper 2, while having guaranteed that control setup 4 sides do not have operating personal, also can make the material in hopper 2 be added in time.
In a kind of implementation column of the present utility model, also comprise that one for supporting the support 3 of hopper 2, hopper 2 is positioned on support 3.Support 3 supports hopper 2, has increased the intensity of hopper, makes hopper 2 when filling material, keep stability.
