Description
Technical field
The utility model belongs to sorting machine technical field, relates to the efficient wind power sorting device of casting used sodium silicate sand recovery.
Background technology
Water-glass sand is a large amount of pattern materials that use of casting industry, because use amount is large, therefore people adopt various technology way recycle-water glass sands to reuse, and regenerating water-glass old sand is considered to one of global problem of casting on boundary, discarded old sand is alkalescence, and not even a blade of grass grows to topple over part.China has over thousands of casting factory to adopt water-glass sand technique, and every day, discarded used sodium silicate sand quantity was surprising.Discarded in a large number if used sodium silicate sand is not recycled, be the significant wastage to limited resources, can cause again serious environmental pollution.
The way that used sodium silicate sand reclaims is a lot, but all must adopt the sorting of multiple physics and chemistry sorting link method synthesis just can achieve the goal, sorting link is a lot, wherein having a link is pneumatic separating, blow with air blast by waiting of naturally falling continuously from feed pipe selected materials exactly, utilize sand grains than great, little this otherness of impurity proportion by the fine impurities blowing of large portion; Sieves filters sand grains, and the impurity filter of larger volume is stayed on screen pack compass screen surface.
For example: publication number is CN203003051U, in the Chinese patent of " a kind of casting used sodium silicate sand recovery wind power sorting device " by name, a kind of technology is disclosed, its structure as shown in Figure 1, comprise cabinet 2, pedestal 11, sieves, point be located at cabinet 2 opposite flanks feed pipe and dust outlet tube, be located at cabinet 2 bottom surfaces discharge nozzle 17, be located at the fall air-blast device of mouthful lower side of feed pipe; Sieves is located at feed pipe and falls between mouth and discharge nozzle 17 entrances; Also comprise the feeding fan 18 that is located at feed pipe import; Feed pipe comprises three charging branched pipes (upper feeding pipe 13, middle feed pipe 14, lower feed pipe 15) of charging house steward 16 and connection charging house steward 16 and cabinet 2, and branched pipe is in the uniform setting of short transverse of cabinet 2; Cabinet 2 is cylinders, connects between cylinder top and the cylinder end, to be provided with motor 1 and to drive the rotating shaft being connected; Air-blast device is three groups of fan blades along the uniform setting of rotating shaft (upper fan blade 12, middle fan blade 6, lower fan blades 9), respectively organizes fan blade (upper fan blade 12, middle fan blade 6, lower fan blade 9) and be located at respectively mouthful lower side that falls of corresponding charging branched pipe (upper feeding pipe 13, middle feed pipe 14, lower feed pipe 15); Under each group fan blade (upper fan blade 12, middle fan blade 6, lower fan blade 9), be all provided with circular sieves (upper sieves 4, middle sieves 7, lower sieves 10); Dust outlet tube is three bodys (upper dust outlet tube 3, middle dust outlet tube 5, lower dust outlet tube 8) that are separately positioned on corresponding charging branched pipe (upper feeding pipe 13, middle feed pipe 14, lower feed pipe 15) opposite.
The air blast direction of its fan blade (upper fan blade 12, middle fan blade 6, lower fan blade 9) arranges upward.
Its charging house steward 16 be arranged in parallel with cylinder cabinet 2, and the air blast direction of feeding fan 18 arranges upward.
Its principle is: in assorting room, waiting to select materials, to send into through feeding fan 18 air blast be just discrete state; Again through three groups of fan blades (upper fan blade 12, middle fan blade 6, lower fan blade 9) step by step air blast rise classification selection by winnowing to blowing up, after two strands of air-flows liquidate, the material degree of seething further strengthens, good separation effect, the rate of recovery is high.
Adopt the casting used sodium silicate sand recovery wind power sorting device of such technology certainly can normally use, but owing in cabinet 2, three groups of fan blades will being set, the too little wind-force deficiency of fan blade, fan blade affects too greatly again blanking to screen net; Structure is not rationally and relatively complicated, and it is also convenient not to safeguard, and result of use is ideal not enough.
Utility model content
For overcoming the deficiencies in the prior art, the utility model provides more advantages of simple of a kind of structure, safeguards more conveniently, and result of use is more preferably cast used sodium silicate sand and reclaimed and use efficient wind power sorting device.
The utility model for the technical scheme that reaches above-mentioned technical purpose and adopt is: casting used sodium silicate sand reclaims use efficient wind power sorting device, comprise cabinet, sieves, divide be located at cabinet opposite flank feed pipe and dust outlet tube, be located at cabinet bottom side discharge nozzle, be located at feed pipe fall mouthful lower side air-blast device, be located at the feeding fan of feed pipe import; Sieves is located at feed pipe and falls between mouth and discharge nozzle entrance; Feed pipe comprises three charging branched pipes of charging house steward and connection charging house steward and cabinet, and branched pipe is in the uniform setting of short transverse of cabinet; Cabinet is cylinder, and charging house steward and cylinder cabinet be arranged in parallel, and the air blast direction of feeding fan arranges upward; Air-blast device is connect cylinder top and be provided with blast pipe between the cylinder end; Air blast blower fan is located at a pucking airduct import; Be distributed with the poroid fresh air inlet of three networkings along air blast tube wall axially spaced-apart, respectively organize air intake mesh and be located at respectively mouthful lower side that falls of corresponding charging branched pipe; Under each group air intake mesh, be all provided with circular sieves.
The hole axle of the mesh fresh air inlet on described air blast tube wall is obliquely to arranging.
The beneficial effects of the utility model are: because air-blast device is connect cylinder top and be provided with blast pipe between the cylinder end; Air blast blower fan is located at a pucking airduct import; Be distributed with the poroid fresh air inlet of three networkings along air blast tube wall axially spaced-apart, respectively organize air intake mesh and be located at respectively mouthful lower side that falls of corresponding charging branched pipe; Under each group air intake mesh, be all provided with circular sieves.By controlling, air blast blower fan is unified to be adjusted the large I of air blast wind-force, there is no moving component in cabinet, does not affect blanking to screen net, rational in infrastructure and relatively simple, safeguards more conveniently, and result of use is better.
