Abstract
The utility model relates to an extrusion feed arrangement of honeycomb formula catalyst, including the barrel, be equipped with feed inlet and discharge gate on the barrel, install the dabber in the barrel, the spindle is equipped with the external splines, first screw rod and second screw rod are installed respectively to the spindle, first screw rod is installed in the feed end, the second screw rod is installed in the discharge end, first screw rod and second screw rod meet in the middle part of the dabber, first screw rod and second screw flight direction are all the same with turning to of dabber, the spiral shell depth facies of the dark and second screw rod of the spiral shell of first screw rod etc, and the pitch of first screw rod is greater than the pitch of second screw rod. The utility model discloses a screw rod of two different pitchs of adjustment forms dark not equidistance screw rods such as multiple, has reduced the dark not reserve quantity of equidistance screw rod such as whole type, has also made things convenient for the change of extruder screw rod, has improved work efficiency. Simultaneously, the length of single screw rod shortens, and the processing degree of difficulty diminishes, has reduced the processing cost.
Description
Technical field
The utility model belongs to cellular catalyst production field, and what be specifically related to a kind of cellular catalyst squeezes into materials device.
Background technology
Current China catalyst dedicated extruder, dark screw rod pusher and the extruding such as general employing one is equidistant, in the process of producing catalyst, because charging is unreasonable with extruding coupling, easily occur catalyst packing inequality causing the low problem of yield rate.Even if be improved to non-constant lead screw charging and extruding, the uneven problem of packing when also can only solve the catalyst extrusion molding of part model, the model of producing catalyst is more, just needs the constant depth variable pitch screw preparing a greater variety of different pitch ratio, improves production equipment cost.Simultaneously because screw rod is more heavier, change the manpower and materials that waste is larger.
Utility model content
In order to solve the problem occurring packing inequality when catalyst is extruded, what the utility model provided a kind of cellular catalyst squeezes into materials device, installs combination, form the constant depth variable pitch screw of different pitch ratio by two dark pitch such as equidistant.
For achieving the above object, the technical scheme taked of the utility model is as follows:
A kind of cellular catalyst squeeze into materials device, comprise machine barrel, in machine barrel, mandrel is installed, machine barrel one end is feed end and is provided with charging aperture, the machine barrel other end is discharge end and is provided with discharging opening, the axis perpendicular of described charging aperture and machine barrel, mandrel is separately installed with the first screw rod and the second screw rod, first screw rod is installed on feed end, second screw rod is installed on discharge end, first screw rod and the second screw rod connect in the middle part of mandrel, first screw rod is all identical with turning to of mandrel with the second screw flight direction, the spiral shell of the first screw rod is dark deeply equal with the spiral shell of the second screw rod, the pitch of the first screw rod is greater than the pitch of the second screw rod.
Preferably, the first screw rod, have gap between the second screw rod and machine barrel.
The beneficial effects of the utility model:
The program is arranged on same mandrel owing to have employed dark equidistant screw rod such as two grades, form the effect of constant depth variable pitch screw, by adjusting the screw rod of two different pitch respectively, multiple different pitch combination can be formed, produce the function of the constant depth variable pitch screw of multiple pitch ratio, decrease the inventory of monolithic devices constant depth variable pitch screw, simultaneously owing to have employed the version of two joint combinations, single screw rod weight, also facilitates the replacing of extruder screw, improves operating efficiency.Meanwhile, the length of single screw rod shortens, and difficulty of processing diminishes, and reduces processing cost.
Accompanying drawing explanation
Fig. 1 is the structural representation squeezing into materials device of cellular catalyst described in the utility model.
Detailed description of the invention
As shown in Figure 1, a kind of cellular catalyst squeeze into materials device, comprise machine barrel 3, machine barrel 3 one end is feed end and is provided with charging aperture 2, machine barrel 3 other end is discharge end and is provided with discharging opening 6, the axis perpendicular of charging aperture 2 and machine barrel 3, mandrel 1 is installed in machine barrel 3, mandrel 1 is separately installed with the first screw rod 4 and the second screw rod 5, first screw rod 4 is installed on feed end, second screw rod 5 is installed on discharge end, first screw rod 4 and the second screw rod 5 connect in the middle part of mandrel, the hand of spiral of the first screw rod 4 and the second screw rod 5 is all identical with turning to of mandrel 1, the spiral shell of the first screw rod 4 is dark deeply equal with the spiral shell of the second screw rod 5, the pitch of the first screw rod 4 is greater than the pitch of the second screw rod 5.
Screw rod (namely the first screw rod 4) Main Function of feed end is transferring raw material, and pitch contributes to greatly improving inlet amount; The screw rod (namely the second screw rod 5) of discharge end, except transferring raw material, also to the further compacting of raw material, contributes to ensureing the packed uniform degree of product so reduce pitch.Extrude the difference of model according to catalyst, the first screw rod 4 and the second screw rod 5 of different pitch can be selected respectively.Extruded in order to ensure, consider that screw rod is because of work expanded by heating, is equipped with gap between the first screw rod 4, second screw rod 5 and machine barrel 3, because the too little meeting in gap causes screw rod and machine barrel 3 to wear and tear, even produces the phenomenon of stuck screw rod simultaneously; Gap too conference affects extrusion capacity and product quality, and production efficiency is low, so should arrange rational gap width according to the diameter of extrusion forming process and screw rod.
Claims (2)
1. a cellular catalyst squeeze into materials device, comprise machine barrel, machine barrel one end is feed end and is provided with charging aperture, the machine barrel other end is discharge end and is provided with discharging opening, the axis perpendicular of described charging aperture and machine barrel, in machine barrel, mandrel is installed, mandrel is provided with external splines, it is characterized in that: mandrel is separately installed with the first screw rod and the second screw rod, first screw rod is installed on feed end, second screw rod is installed on discharge end, first screw rod and the second screw rod connect in the middle part of mandrel, first screw rod is all identical with turning to of mandrel with the second screw flight direction, the spiral shell of the first screw rod is dark deeply equal with the spiral shell of the second screw rod, and the pitch of the first screw rod is greater than the pitch of the second screw rod.
2. a kind of cellular catalyst as claimed in claim 1 squeeze into materials device, it is characterized in that: the first screw rod, between the second screw rod and machine barrel, all have gap.
