Abstract
The utility model relates to a spiral feeder for industrial dosing production, which comprises a bracket, a power mechanism, a shell, a spiral propulsion shaft, a blanking port and a discharging port, wherein the blanking port is arranged under a feeding port; sheet spiral sections at intervals are arranged at the feeding end of the spiral propulsion shaft; and a double spiral blade is designed at the rear end of the spiral propulsion shaft. After a feeder is improved according to the utility model, the practical disadvantageous problem of the spiral feeder is effectively solved, the stable feeding of the materials is ensured and the difference value is more accurately controlled.
Description
Technical field
The utility model belongs to a kind of charger of conveying machinery apparatus field, is specifically related to the production of a kind of industry batching and uses self-conveyor feed.
Background technology
At present, in the glass production industry, the batching pattern of automatic weighing system is generally adopted in the preparation of batch; Feeding device adopts the form of screw feeding usually, when reinforced, is undertaken by the variable-frequency motor of Frequency Converter Control; Two grades of speed of fast shelves and slow shelves are arranged; I.e. two kinds of reinforced states of " fast reinforced " and " reinforced slowly " when gravimetric value and blanking target weight differ some (drop amount), promptly send and stop the signal that feeds in raw material; Make the material (drop amount) that falls just in time make it reach setting value in the air, a kind of material weighing finishes.
Yet; In actual production, several kinds of situation below can occurring make equipment operation unstable: owing to factors such as material composition, moisture and granularities, material is adsorbed on the bin wall (1); Make and form " hole " in the material blanking process of feed bin; During blanking, raw material pours electronic scale through the gap of screw feeding engine housing and blade once more, and over feeding is reported to the police needs artificial treatment.(2) because the feed bin volume is big, raw material is partly conducted oneself with dignity and is pressed on the charger spiral promoting shaft of below, makes charger when " fast reinforced " starts, and detent torque is big, and the motor feels hot overload alarm needs artificial treatment.(3) self-conveyor feed is in " reinforced slowly " process; When gravimetric value and blanking target weight differ some (drop amount), promptly send and stop reinforced signal, make the material (drop amount) that falls just in time make it reach setting value in the air; Because the viscosity characteristics of material; It is unstable the blanking amount to occur, and reinforced error is big, thereby influences the weighing accuracy rate of raw material.
The utility model content:
The utility model provides a kind of industry batching to produce and uses self-conveyor feed to self-conveyor feed above-mentioned deficiency in actual production.
The utility model addresses the above problem the solution that is adopted: a kind of industry batching is produced and is used self-conveyor feed, comprises support, actuating unit; Shell, spiral promoting shaft, feed opening; Discharging opening; It is characterized in that: below charge door, be provided with a feed opening, the feed end of spiral promoting shaft is provided with spaced sheet spiral section, and the back end design of spiral promoting shaft becomes the double helix blade.
Feed opening is interior semicircular opening shape, matches with the shape of helicallobe on axis projection, and its gap is 2-10mm.
The blade of sheet spiral section is uniformly-spaced arranged, and sheet helicallobe length is greater than spiral material feeding segment length.
Helicallobe before the spiral promoting shaft convey materials blanking point adopts double blade structure, and its width is a blade pitch.
The utility model can solve the unfavorable problem that self-conveyor feed occurs after charger is improved in fact, can guarantee that the material charging is steady, and control drop amount is more accurate.Feeding mouth at charger is installed a special feed opening, and there is interior semicircular opening the feed opening below, places spiral promoting shaft blade top, with the helicallobe excircle a spot of gap is arranged, and prevents " dashing material " phenomenon.The Blade Design of charger spiral promoting shaft material feeding section is the sheet blade construction, the resistance when reducing to start.The Blade Design of the blanking section of charger spiral promoting shaft is the double helix blade construction, when reinforced stopping, reducing the drop amount of aerial blanking.
Description of drawings:
Fig. 1 is the scheme drawing of the utility model;
Fig. 2 is the section-drawing of the utility model;
Fig. 3 is the perspective view of feed opening;
Fig. 4 is the sheet helicallobe project organization figure of the utility model.
The specific embodiment
Referring to Fig. 1-Fig. 4, in actual production, the blade outside diameter that a kind of self-conveyor feed is arranged is 200mm, and blade pitch is 200mm, and it is said to press the utility model, and self-conveyor feed is improved, and is shown in Figure 1 like reference.Special feed opening is installed in entrance at charger; Its length is 400mm, and feed opening 1 is interior semicircular opening shape, and the semicircular opening diameter is 210mm; Feed opening 1 is 5mm with the spacing of helicallobe; Can actv. stop that feed bin dashes material because of what caused in " hole ", its material is elected stainless steel material as, as shown in Figures 2 and 3.Charger material feeding section is the part spiral section of feed opening below, adopts the sheet Blade Design, the resistance of material when starting to reduce spiral; Prevent that current of electric is big, the overload phenomenon occurs, its sheet length of blade is 600mm; Should be greater than feed opening length 400mm, like Fig. 4.The Blade Design of charger spiral promoting shaft blanking section is a double blade structure, and its length of blade is a pitch 200mm, in process of production; When system sends when stopping reinforced signal; Aerial blanking amount is 1/2 of single blade construction, and reinforced error is little, helps to guarantee the weighing accuracy rate of raw material.
