Description
Technical field
The present invention relates to the auxiliary feeding device of a kind of screw rod banded extruder, be specifically related to a kind of banded extruder feed arrangement.
Background technology
The molding of catalyst refers to the most mutually assemble all kinds of powder body, granule or molten mass raw material, makes the operating unit of the solid catalyst particle with definite shape, size and intensity, has catalytic mechanical intensity and performance and has a certain impact.Extrusion moulding is through carrying, extrude, extrude and the shaping of catalyst method of cutting series of steps by material, screw rod banded extruder is common extrusion shaping machine, material is after extruded tube sent into by feed hopper, material is promoted forward by rotated screw rod, along with material is pushed ahead, helical blade produces the strongest compression stress to powder body.The compressed die head that is advanced to of material is extruded into strip through porous plate, then cuts off molding.
Wherein single-screw extruder design is simple, easily manufactures, and operation and maintenance is the most convenient, and use cost is low, is widely used in laboratory research or smallest catalyst are developed.But due to the conveying effect of banded extruder mainly by frictional force so that its charging performance is restricted.Shaping of catalyst process is usually that to enter back into banded extruder after the most first raw material and binding agent or lubricant being carried out kneading extruded, the especially material after kneading only relies on self weight and enters extrusion cylinder to easily cause charging uneven and affect end product quality, even there is " bridge formation " phenomenon, make rotary screw zero load operation, damage former.
Summary of the invention
The technical problem to be solved is single-screw extruder charging difficulty, it is therefore intended that provides a kind of banded extruder feed arrangement, positive feed, makes the addition extrusion cylinder of material continuous uniform, and feed arrangement simple in construction.
The present invention is achieved through the following technical solutions:
A kind of banded extruder feed arrangement, including extrusion cylinder, is provided with extrusion screw rod in extrusion cylinder, charging aperture and discharging opening it is additionally provided with on extrusion cylinder, described charging aperture is provided with feed hopper, and described feed hopper is provided with vibrator, and described feed hopper lower port is connected and fixed on charging aperture by rubber soft joint.
In prior art, single-screw extruder includes support, support is fixed with transmission case and extrusion cylinder, transmission case and extrusion cylinder and is tightly connected.Being provided with drive mechanism in transmission case, drive mechanism includes power transmission shaft, one end of power transmission shaft be connected with motor and decelerator successively, the other end of power transmission shaft is connected with extrusion screw rod by shaft coupling.Accommodating extrusion screw rod at extrusion cylinder, on extrusion cylinder, the one end near transmission case is provided with charging aperture, and the extrusion cylinder other end is positioned at extrusion screw rod axial line and is provided with discharging opening.
Charging aperture arranges feed hopper, feed hopper is fixedly installed vibrator.When charging starts, Vibration on Start-up device, drive feed hopper shake so that material shake in feed hopper, accelerate material and fall in extrusion cylinder, effectively prevent material caking or blocking, and contribute to promoting the charging of material continuous uniform.Feed hopper is connected with charging aperture by rubber soft joint, by flange or bolt are fixing, one end of rubber soft joint can be connected feed hopper, and the other end of rubber soft joint is fixed on charging aperture by flange or bolt.In in working order, rubber soft joint is installed and can effectively alleviate the vibrations of the vibrator impact on extrusion device, ensure that banded extruder works in metastable environment, make extrusion screw extruding active force uniform.
Described vibrator is pneumatic vibrator, and described pneumatic vibrator is fixed on the lateral wall of feed hopper.
Pneumatic vibrator is using compressed air as power source, and air consumption is little, the safest but also energy-conservation.And its volume is little, fault is few, installs and safeguard simple, being very suitable for being arranged on small-sized single-screw extruder.Pneumatic vibrator is installed on the lateral wall of feed hopper, and feed hopper can be driven to shake uniform feeding, can prevent again material from pneumatic vibrator causing corrosion or pollutes.
Described extrusion screw rod is diameter progressive screw, and being positioned at the stock screw overall diameter of extrusion cylinder charging aperture section with the stock screw overall diameter ratio of extrusion cylinder extruded segment is 1.1～1.6.
Stock screw in extrusion cylinder has conveying material and extruded effect, and the stock screw being positioned at discharging opening section acts primarily as conveying effect, and another section of stock screw just plays conveying material and extruded effect.Extrusion screw rod in extrusion cylinder is set to diameter progressive screw, make the overall diameter being positioned at the stock screw of the extrusion cylinder charging aperture section stock screw overall diameter more than extrusion cylinder extruded segment, so stock screw has mechanical agitation conveying effect to the material at the charging aperture even material of feeding funnel bottom part, further enhance the charging rate of material, ensure that material by charging aperture to extruded segment uniform feeding, " short-circuit " the unfavorable phenomenons such as fed material from being blocked will not occur.
The described stock screw overall diameter of extrusion cylinder charging aperture section and the stock screw overall diameter ratio of extrusion cylinder material extrusion section of being positioned at is 1.25.
It is positioned at the stock screw overall diameter of extrusion cylinder charging aperture section with the stock screw overall diameter ratio of extrusion cylinder material extrusion section less than 1.1, then cannot stir transmission rubber soft joint position and the material of feeding funnel bottom part, and ratio is more than 1.6, affect the normal conveying of material on the contrary.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, the present invention is a kind of banded extruder feed arrangement, by being fixedly installed vibrator shake charging on feed hopper, and uses reducing extruding screw, material can be forced to enter, and beneficially material uniformly enters and carries；
2, the present invention makes a kind of banded extruder feed arrangement, can effectively alleviate the vibrations of the vibrator impact on extrusion device by installing rubber soft joint, ensure that banded extruder works in metastable environment, make extrusion screw extruding active force uniform；
3, the present invention is a kind of banded extruder feed arrangement, and simple in construction, operation and maintenance is with low cost, and positive feed effect is notable.
