The structure that this closed feed proportioning system is matched by adopting one-level conveying worm and deuterostrophies conveyer, compared with the feed proportioning system of single conveying worm in prior art, dredging effect can be realized, avoid the phenomenon of feed blocking at helical feed machine inlet capable, and accurate measurement, makes feed bin realize continuous uniform blanking.
Description
Technical field
The utility model relates to dispensing equipment technical field, is specifically related to a kind of closed feed proportioning system.
Background technology
The raw materials for production of snow-melting agent are mainly the pulverulent solids such as sodium chloride, calcium chloride, in prior art, adopt directly manually prepared burden and measures more in production environment, aforesaid operations not only can make the dust that produces a large amount of in production space, and easily accidents caused, has potential safety hazard. And some inorganic salts can absorb airborne moisture, the material in hopper is caused to harden. Improved technical scheme adopts conveyer belt to weigh feeding, or disclosed in CN102431093B, adopt the feeding of batching dolly, in the seal box of sealing, dust accumulation is many, and feeding machine structure is loaded down with trivial details, the long-time stability difference of LOAD CELLS, after long-time use, there will be performance inconsistency, finally can lose efficacy because of aging or fatigue factor, furnish component heterogeneity can directly affect the quality of product. Preferred technical scheme adopts feed screw to be connected with feed bin, but load is wayward, and there will be the phenomenon of feed blocking screw feeding machine inlet capable during various materials proportioning. Therefore, be necessary feed proportioning system of the prior art to carry out structure improvement.

For achieving the above object, the technical solution of the utility model is: a kind of closed feed proportioning system, it is characterized in that, described feed proportioning system comprises at least two feed bins, the top of described feed bin is provided with charging aperture, the bottom of described feed bin is connected with the charging aperture of one-level conveying worm respectively by pipeline, the discharging opening of described one-level conveying worm is connected with the charging aperture of deuterostrophies conveyer by pipeline, pipeline between feed bin bottom and one-level helical feed machine inlet capable is connected with powder valve, powder flow gauge is provided with in pipeline between described powder valve and the charging aperture of one-level conveying worm.
For accurate-metering powder flow, realize the automatic control to material load in feed bin, preferred technical scheme is that described powder flow is counted static powder flow gauge or impulse type powder flow gauge, and powder valve is pneumatic powder butterfly valve.
In order to avoid material remains in conveying worm, preferred technical scheme is that the feed end of one-level conveying worm is higher than discharge end.
In order to reduce steam inlet in feed bin, preferred technical scheme is to be equipped with lid on described charging aperture.
In order to avoid hardening of material in feed bin affects the flow measurement of discharging, preferred technical scheme is to be provided with rotating shaft in described feed bin, and the bottom of described rotating shaft is provided with breaks up blade, and described rotating shaft is connected with drive motors by driving member.
In order to avoid material hardens at feed bin inwall, preferred technical scheme is that the low side outer surface of described feed bin is fixedly installed vibrating motor.
Advantage of the present utility model and beneficial effect are:
The structure that this closed feed proportioning system is matched by adopting one-level conveying worm and deuterostrophies conveyer, compared with the feed proportioning system of single conveying worm in prior art, dredging effect can be realized, avoid the phenomenon of feed blocking at helical feed machine inlet capable, and accurate measurement, makes feed bin realize continuous uniform blanking.
