In one embodiment, the ratio of the drying cavity diameter to the height of the drying tower is not more than 1: 5.
in one embodiment, the ratio of the outlet end pipe diameter of the feeding pump to the drying cavity diameter is not more than 1: 4.
in one embodiment, the outlet end of the feeding pump extends into the drying tower and is in arc transition with a bending part extending upwards along the axial line of the drying tower, and the bending angle is not less than 90 degrees.
In one embodiment, the lower part of the drying tower is in an inverted cone shape, the bottom opening is connected with a discharge pipe, and the discharge pipe is connected with the discharge pump.
In one embodiment, the discharge pump is provided with an exhaust fan.
Advantageous effects
Foretell circulation formula material drying device, in the drying tower was gone into by the delivery pump to the material, supreme blowout from bottom to top in the delivery pump exit, formed from last circulation down in the stoving intracavity, dried the intracavity back, by ejection of compact pump suction stoving chamber from the drying tower bottom, can not form in the stoving intracavity and block up long-pending, avoid at the stoving intracavity putty, reduced troubleshooting probability.
Drawings
FIG. 1 is a schematic diagram of a circulation-type material drying apparatus according to an embodiment;
fig. 2 is a schematic diagram of an internal structure of a circulation type material drying apparatus in an embodiment.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1 and fig. 2, a circulation material drying device includes a feeding pump 22, a drying tower 31 and a discharging pump 5; the inlet end of the feeding pump 22 is connected to the material conveying equipment 11, the outlet end of the feeding pump 22 extends into the drying tower 31 from the side wall of the drying tower 31 and extends upwards along the axial lead of the drying tower 31, and the outlet of the feeding pump 22 is arranged near the center of the top of the drying tower 31; a cylindrical drying cavity is formed in the drying tower 31; the discharging pump 5 is connected to the bottom of the drying tower 31.
During operation, the material is gone into drying tower 31 by the pump of pay-off 22 pump in, and the blowout is supreme from bottom to top in the delivery pump 22 exit, forms from last circulation down in the stoving intracavity, is dried the back at the stoving intracavity, is sucked out the stoving chamber by discharge pump 5 from drying tower 31 bottom, can not form in the stoving intracavity and block up long-pending, avoids at the stoving intracavity putty, has reduced troubleshooting's probability.
Wherein, the feeding pump 22 entrance point can be provided with the feeder hopper 21, and the feeder hopper sets up in the conveyer belt 12 below of material conveying equipment 11, and the material is carried to the feeder hopper and is followed feeder hopper 21 and fall into the pipeline of the interior packing feeding pump 22 of feeding pump 22 downwards, is convenient for feeding pump 22 pump sending material.
In one embodiment, the drying chamber diameter to height ratio of the drying tower 31 is not greater than 1: 5. because of the material is by the export blowout back of conveying pump 22, from last circulation down of formation in the stoving intracavity, the operation of drying is carried out in the stoving intracavity, if the stoving chamber diameter of drying tower 31 is too big with the high ratio, then spun material is difficult to reach the stoving chamber lateral wall on the one hand, causes the stoving intracavity space extravagant, on the other hand material whereabouts process is short excessively, and the stoving effect is unsatisfactory, so the stoving chamber diameter that rationally sets up drying tower 31 and the high ratio are not more than 1: 5.
in one embodiment, the ratio of the outlet end pipe diameter of the feed pump 22 to the drying chamber diameter is not more than 1: 4. if 22 exit end pipe diameters of feed pump are too big, then 22 exit ends of feed pump occupy 31 inner spaces of drying tower too big, and easily cause the interference to the circulation in the drying tower 31, are unfavorable for drying, so rationally set up 22 exit end pipe diameters of feed pump and drying chamber diameter's ratio and be not more than 1: 4
In one embodiment, the outlet end of the feed pump 22 extends into the drying tower 31 and is in arc transition with a bending part extending upwards along the axial line of the drying tower 31, and the bending angle is not less than 90 °. So that the material is not easy to be accumulated on the outlet pipe wall of the feeding pump 22 when falling.
In one embodiment, the lower part of the drying tower 31 is in an inverted cone shape, the bottom opening is connected with a discharge pipe 32, and the discharge pipe 32 is connected with the discharge pump 5. After the materials are dried, the materials fall to the discharge pipe 32 along the inverted cone structure at the lower part of the drying tower 31, and are not easy to accumulate at the bottom of the drying tower 31.
In one of the embodiments, the discharge pump 5 is provided with a suction fan 4. The dried materials are conveniently and timely sucked out by the suction fan 4.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
