Abstract
The utility model discloses a permanent magnet barrel for magnetic rice separation. The permanent magnet barrel comprises a straight pipe and a magnetic body, wherein the magnetic body is fixed on the inner wall of the straight pipe through brackets. The permanent magnet barrel is characterized in that the upper part of the magnetic body is conical; a plurality of layers of annular magnetic separation rings are arranged on the magnetic body; dripping plate rings are correspondingly arranged on the inner wall of the straight pipe above the annular magnetic separation rings; the dripping plate rings can average falling materials to enable the materials to be uniformly dispersed and can also guide the materials to the magnetic body to enable the materials to slowly flow down from the conical surface close to the upper part of the magnetic body; some pieces of rebounded rice can continuously return to a position near to the magnetic body and slowly fall down, so that the efficiency for removing magnetic metal impurities is improved. The permanent magnet barrel is good in magnetic separation effect; the removal rate of the magnetic metal impurities is up to 99.7 percent.
Description
Technical field
The utility model belongs to processing of farm products field, is specifically related to a kind of pipe magnetic separator for paddy magnetic separation.
Background technology
Magnetic separation is the method for utilizing magnetic force that magnetic metal impurity in material is removed, when material is when the magnetic field, because paddy is non-magnetic object, be not subject to the effect in magnetic field and freely pass through, magnetic metal impurity is easily magnetized, and inhales mutually and remove with opposite pole.The condition of magnetic metal impurity separation is that magnetic field is greater than and its reaction force the magnetic force of magnetic metal impurity, traditional pipe magnetic separator is just comprised of simple straight tube and tubular permanent magnet, magnetic separation poor effect, for the absorption away from the magnetisable material of magnet near barrel, effect is poor especially.
Summary of the invention
For above-mentioned problems of the prior art, the utility model provides a kind of pipe magnetic separator for paddy magnetic separation, and magnetic separation is effective, and magnetic metal impurity clearance is up to 99.7%.
The problem existing for solving above-mentioned prior art, the technological means that the utility model is taked is: a kind of pipe magnetic separator for paddy magnetic separation, comprise straight tube and magnet, described magnet is fixed on straight tube inwall by support, it is characterized in that, described magnet top is taper, and described magnet is provided with multi-layer annular magnetic separation ring, on the straight tube inwall of described annular magnetic ring selection top correspondence, is provided with accordingly and drops down plate ring.Drop down the material that plate ring can evenly fall on the one hand, it is uniformly dispersed, on the other hand, can be by material guiding magnet, material is slowly flowed down, the paddy that some are rebounded, the guiding of dropping down plate ring by lower floor from the conical surface on magnet top from close, near can continuing to get back to magnet, slowly fall, increased the efficiency that magnetic metal impurity is removed.
The described angle that drops down plate ring and straight tube inwall is 45-60 °.
The number of described magnetic separation ring is more than or equal to the number of dropping down plate ring.
The number of described magnetic separation ring is 3-7, described in drop down plate ring number be 2-7.
Pipe magnetic separator for paddy magnetic separation described in the utility model, can constantly collect the paddy of dispersion, make it from close magnet or slowly flow down along magnet, increased the efficiency that magnetic metal impurity is removed, and the setting of magnetic separation ring, can slow down the time that paddy flows down on the one hand, can increase on the other hand the adsorption area of magnet, from another point of view, improved the adsorption rate of magnetic impurity.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Wherein: 1 straight tube, 2 magnets, 3 supports, 4 magnetic separation rings, 5 drop down plate ring.
