Abstract
The utility model relates to an extrusion molding device, the main inhomogeneous problem that influences the granulation quality of catalyst extrusion molding in -process extruded velocity that has now of solving. The utility model discloses an adopt the device is including extruding machine, template, constant voltage subassembly, wherein, the constant voltage subassembly sets up between template and extruding machine export, and the constant voltage subassembly is closely laminated with the template, this problem has been solved with the technical scheme that extruding machine passes through bolted connection betterly to template, constant voltage subassembly, can be used to in the extrusion molding production of catalyst.
Description
Technical field
The utility model relates to a kind of extruded moulding device, particularly relates to a kind of extruded moulding device for catalyst preparing.
Background technology
Shaping of catalyst is the important step of industrial catalyst preparation section, and according to the different requirements of catalyst, custom catalysts has granular, bar shaped, spherical and other shapes.Wherein bar shaped catalyst is that industrial catalyst applies a wider type.Traditional bar shaped catalyst preparation technology be by kneading after material extruded the strip material with different cross section shapes such as cylindrical, clover, annulus by banded extruder, be then prepared into final finished catalyst through processes such as postorder drying, roastings.Extrusion operation adopts the horizontal banded extruder of singe screw usually, and this kind of banded extruder has that thrust is large, the feature of continuous discharge, but in template almost the shaping speed in each hole be different, extrusion discharging speed uniformity is very poor, directly affects follow-up granulation quality.
Chinese patent CN2666647Y discloses a kind of banded extruder, and structure and the existing extrusion equipment of the employing of this banded extruder are substantially similar, can not solve the problem of discharging speed lack of homogeneity.
Chinese patent CN201538027U discloses a kind of large-scale scale polymer product extrusion molding device, this device realizes extruding evenly by adopting multilevel branch runner and control set for adjusting, structure is very complicated, and adopt planetary gear pump to carry out mass transport, be not suitable for the catalyst extrusion molding of high solids content completely.
Summary of the invention
Technical problem to be solved in the utility model there is extruded velocity lack of homogeneity in existing catalyst extruded forming process, affects the problem of granulation quality, provides a kind of new extruded moulding device.It is even that this extruded moulding device has extrusion discharging speed, thus reach the advantage of higher granulation quality.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows: a kind of extruded moulding device, and described device comprises banded extruder, template, constant voltage assembly; Wherein, constant voltage assembly is arranged between template and banded extruder export, and constant voltage assembly and template fit tightly; Template, constant voltage assembly and banded extruder are bolted.
In technique scheme, preferably, described banded extruder is single-screw extruder.
In technique scheme, preferably, described template is rounded porous template.
In technique scheme, preferably, described constant voltage assembly is the circular components with annular channel.
In technique scheme, preferably, the annular channel of described constant voltage assembly is reverse taper passage.
The utility model is owing to have employed the constant voltage assembly being provided with reverse taper passage, and extrusion discharging speed is even, and postorder granulation quality is higher, achieves good effect.

Fig. 1 is the schematic diagram of the utility model extruded moulding device.
Fig. 2 is the schematic diagram of adopted rounded porous template.
Fig. 3 is the schematic diagram that adopted constant voltage assembly and model sheetinstallat combine.
In Fig. 1,1 is banded extruder, and 2 is constant voltage assembly, and 3 is template.
In Fig. 2,3 is rounded porous template.
In Fig. 3,2 is constant voltage assembly, and 2a is bolt hole, and 2b is reverse taper passage, and 3 is template.
The following examples are described further with regard to the utility model, but the utility model is not by the restriction of embodiment.
Detailed description of the invention
[embodiment 1]
Design extruded moulding device by Fig. 1 to Fig. 3, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Catalyst feed after kneading enters banded extruder 1 and carries out extrusion, is entered the annular channel of constant voltage assembly 2 by discharging opening, is formed the strip material with certain cross sectional shape after material shunts constant voltage in constant voltage assembly passage by foraminous die plate 3.Preferably, as shown in Figure 3, constant voltage assembly 2 is provided with reverse taper passage 2b, guarantees that material obtains good constant voltage effect.The utility model have employed constant voltage assembly, compared with traditional banded extruder, material extruded velocity evenly, subsequent granulation quality is higher.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; multiple modification can be carried out to the technical solution of the utility model, all belong to protection domain of the present utility model.
