Description
The utility model relates to a kind of cold burden machine of solid material, and dry type cold burden machine is shed in particularly a kind of rotation.
The industrial frequent block or granular high-temp solid material of cooling that needs, the block high temperature cinder of coal-burning boiler also needs cooling.The cooling of solid material has two kinds of wet type and dry types usually.The wet type cooling is directly to drop into high-temperature material in the water or water sprinkling cooling, and this type of cooling is very simple, and cooling effect is also fine, but changes the performance of material sometimes and form contaminated wastewater, and its application is restricted; Dry type cooling is divided into air-cooled again and two kinds of indirect water-coolings usually, and wherein, the cooling effect of indirect water-cooling is relatively good, sometimes also with air-cooled as auxiliary cooling provision.
The indirect water-cooling dry type cold burden machine of using nearly all is to pass through cooling water in the interlayer of pair of lamina cylindrical shell at present, and high-temperature material is advanced to another side lentamente from one side in simplified, with the cooling water partition heat exchange cooling in the interlayer.The main difference of various cold burden machines is the mode that material is pushed ahead, the most frequently used a kind of be fixing double-deck simplified in rotation by screw propulsion rod, material is advanced to another side lentamente from one side, the shortcoming of this method is material essentially no stirring in the process that advances, so inhomogeneous cooling is even, cooling effect is poor, and, bulk materials easily gets stuck, the wearing and tearing of screw propulsion rod and hard material are also relatively more serious, its a kind of modified is that helical blade directly is welded in Nei Jiannei, by the simplified direct rotation of bilayer material is advanced lentamente along helical blade forward, thereby has saved screw propulsion rod.When using this propulsion method, bulk materials is difficult for getting stuck, and does not also have the wear problem of screw propulsion rod, but that material stirs when advancing is still insufficient, cools off still inhomogeneously, and cooling effect is still undesirable.And, more complicated on the welding helical blade technology in inner core.
The purpose of this utility model is will provide a kind of it is stirred fully, thus with the double-layer barrel interlayer in cooling water heat exchange equably, cooling effect is good, and is simple in structure, dry type cold burden machine is shed in rotation easy to process.
It is as follows that the structure and the course of work of dry type cold burden machine shed in rotation: the double-layered cylinder by cooling water in interlayer, be bearing on 4 rollers by two support rings that are welded on the outer cylinder body, make one of them roller rotation with motor by reducing gear, make the double-layered cylinder rotation by frictional drive again with support ring, on the inwall of double-layered cylinder, be fixed with the polylith material and shed plate, material is shed plate for axially welding fixing strip flat board along inner core, it is simple in structure, and is easy to process.During the double-layered cylinder rotation, material is shed strip and material rotation together, after material goes to certain altitude, just can overcome and shed the frictional force between the plate and shed downwards, material is stirred fully, with the cooling water heat exchange cooling equably in the double-layered cylinder interlayer, cooling effect is improved greatly, the supporting of double-layered cylinder makes it downward-sloping to exporting into suitable angle [alpha] from material inlet, like this, when double-layered cylinder was static, the rubbing action of material and tube inwall made the material can be to front slide, but when double-layered cylinder rotates, material just can be in the process that rotation is shed, advance to outlet by import step by step, the material push structure is simplified widely, and the phenomenon that can not get stuck.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the structural representation that dry type cold burden machine is shed in rotation,
Fig. 2 sheds the schematic diagram of propelling for the material rotation.
With reference to Fig. 1, rotation is shed dry type cold burden machine and is made up of double-layered cylinder (1), 4 rollers (2), 8 bearing blocks (3), base plate (4), high (5), low support (6), motor (7), reducing gear (8), water inlet pipe (9), 2 water distribution mechanisms (10), 2 T shape water-supply-pipes (11), outlet pipe (12) and the feeder (13) etc. of supporting.Be welded with 2 support rings (14) on the outer wall of double-layered cylinder (1), be fixed with the polylith material on the inwall and shed plate (15).
Cooling water enters the interlayer of double-layered cylinder (1) through water distribution mechanism (10), T shape water-supply-pipe (11) from water inlet pipe (9), with double-layered cylinder (1) in material partition cooling heat transferring after, through another root T shape water-supply-pipe (11), water distribution mechanism (10), discharge from outlet pipe (12).
2 support rings (14) of double-layered cylinder (1) are bearing on 4 rollers (2), and 4 rollers (2) are bearing on 8 bearing blocks (3), and bearing block (3) is fixed on the base plate (4), and double-layered cylinder (1) flatly is installed on the base plate (4).(5) are supported and low support (6) are supported with high in base plate (4) bottom, make base plate (4) and ground level be inclined to a suitable angle [alpha], thus make double-layered cylinder (1) from material inlet to exporting downward-sloping one suitable angle [alpha].Motor (7) drives a roller (2) through reducing gear (8), makes its rotation, again by with the rubbing action of support ring (14), drive double-layered cylinder (1) rotation.High-temperature material enters the interior letter of double-layered cylinder (1) from feeder (13), shed plate (15) drive by the polylith material that is fixed on the inner tube wall, rotation is shed, progressively advance to outlet by import, material is shed plate (15) and is preferably the strip flat board that axially welds along the tube inwall, it is simple in structure, and is easy to process.
With reference to Fig. 2, double-layered cylinder (1) satisfies tg α＜μ with the tilt angle alpha of ground level
1Restrictive condition, μ wherein
1Be the coefficient of friction of material with the tube inwall.When tube is static, material in the tube because of with the not slippage forward of rubbing action of tube inwall, but when double-layered cylinder (1) rotated, material was shed plate (15) driven rotary by material, just can overcome when becoming the β angle with ground level and material is shed the frictional force between the plate (15) and shed downwards.The size at β angle depends on material and sheds coefficientoffriction between the plate (15)
2, μ
2=tg β.The α because the axis of double-layered cylinder (1) and horizontal plane have angle, thus when material is shed downwards, can not with the cross section of axis quadrature in fall, but with the ground level vertical drop, promptly become a α angle with the orthogonal cross-sections of axis.Thereby material is whenever shed once, can pass apart from S S-htg α forward along the axis direction of double-layered cylinder (1).H be material with the axis orthogonal cross-sections in leave height, like this, material just can progressively be advanced into discharging opening from charging aperture after repeatedly rotation is shed, discharge the cold burden machine.
Because material is constantly shed propelling, it stirs very abundant, can with the cooling water heat exchange cooling equably in double-layered cylinder (1) interlayer, cooling effect is improved widely, and, the air stream that the interior gravity-flow ventilation of double-layered cylinder (1) forms also forms stronger auxiliary convection current cooling with material, has more strengthened the cooling effect of material.Thereby, can in short cylindrical shell, finish necessary cooling.Because it is material is shed plate (15) for to be welded on the strip flat board parallel with axis on double-layered cylinder (1) inwall, simple in structure, easy to process again, can not produce the bulk materials phenomenon that gets stuck, thereby safe and reliable, cost decline, advantage is obvious.
The dry type cooling that dry type cold burden machine can be widely used in industrial multiple bulk or graininess high-temperature material is shed in this rotation, also can be used for the dry type cooling of the high temperature cinder of coal-burning boiler, to improve its activity, helps comprehensive utilization and reduces environmental pollution.
