The safety roller unit is used for kneading and sheet grinding of a flexible explosive and prevents the explosive from flowing towards bearings at two ends in the process of kneading and sheet grinding.
Description
Technical field
The present invention relates to a kind of drum apparatus, be specifically related to a kind of drum apparatus of mediating for explosive, be applicable to the mixing of plastic mixture.
Background technology
It is that the powder type explosive tentatively having mixed and high polymer binder are continued to mediate by drum apparatus the process that rolls and then form uniform sheet explosive that flexible explosive is mediated stone roller blade technolgy.In mediating compaction technology, by the rotation of two cylinders, explosive and binding agent disperse to continue evenly to mix by intermolecular slippage between two cylinders, are finally rolled into sheet or strip.In mediating the flexible explosive grinding in blade technolgy, be sticky plastic state explosive finished product or the work in-process material that possesses certain detonation ability, flexible explosive is mediated stone roller sheet and is generally adopted cylinder to grind sheet machine, in the process of rolling, material easily flows to cylinder two ends, after the rolling bearing of inflow two ends, at bearing internal friction, easily there is burning and explosive reaction.On rolling bearing, installing seal approach additional has certain effect, but can only reduce because relative movement between cylinder and equipment causes seal approach the probability that explosive enters rolling bearing, can not get rid of potential safety hazard.
Summary of the invention
In order to solve shortcomings and deficiencies of the prior art, the invention provides a kind of drum apparatus that grinds sheet of mediating for explosive.
To achieve these goals, safe drum apparatus provided by the invention, is comprised of propulsion source, drive roll, passive cylinder, power shaft, safety groove, and described drive roll is connected on propulsion source through power shaft is parallel with passive cylinder; On drive roll and passive cylinder, there is safety groove; Described safety groove and the angle a of centre of the drum are at 0～45 degree, and safety groove and cylinder two ends angle b are at 45～90 degree, and a is less than b; On safety groove, can increase the thread belt of convex.
Safety groove is symmetrically distributed in drive roll and passive cylinder two ends, at least 1 of every end safety groove quantity.
Advantage of the present invention: (1) mediate to be ground explosive in sheet process and can not flowed to bearings at both ends direction, has got rid of that explosive enters rolling bearing and the potential safety hazard that reacts.(2) mediate to grind in sheet process explosive without loss of material and can operate continuously, material effective rate of utilization and working efficiency improve.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.In figure: 1-drive roll, the passive cylinder of 2-, 3-power shaft, 4-safety groove, 5-thread belt, 6-propulsion source; A-safety groove and centre of the drum's angle, b-safety groove and cylinder two ends angle.
Embodiment
Below in conjunction with drawings and Examples, particular content of the present invention is described in more detail.
Below provide specific embodiments of the invention, it should be noted that the present invention is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection scope of the present invention.
As shown in Figure 1, safe drum apparatus drive roll 1 is connected on propulsion source 6 by power shaft 3 is parallel with passive cylinder 2; On drive roll 1 and passive cylinder 2, have safety groove 4, safety groove 4 is symmetrically distributed in drive roll 1 and passive cylinder 2 two ends, and every end safety groove 4 quantity are more than or equal to 1.Safety groove 4 is with the angle a of centre of the drum at 0～45 degree, and safety groove 4 is with cylinder two ends angle b at 45～90 degree, and described safety groove 4 is less than safety groove 4 and cylinder two ends angle b with the angle a of centre of the drum.The thread belt 5 that has convex on safety groove 4.
Working process of the present invention: flexible explosive is mediated and ground in sheet process, at propulsion source 6, drive under power shaft 3 rotations, drive drive roll 1 and passive cylinder 2 to rotate, explosive material enters cylinder from drum apparatus top, and rolled in the rolling process of drive roll 1 and passive cylinder 2, wherein partial material flows out downwards, and partial material is disperseed to two ends, enters two ends safety groove 4; Thread belt 5 in safety groove 4 drives material movement; Safety groove 4 is less than safety groove 4 and cylinder two ends angle b with the angle a of centre of the drum, and material compresses to centre of the drum, and material can not crossed safety groove 4 and flow to power shaft 3.
Embodiment 1:
(1) according to octogen 880g, compound binding agent 90g, tetrafluoroethylene 30g, test, wherein the silicon rubber of compound binding agent and viton mass ratio are 1:3.5, after manual stirring 5min, use.
(2) parameter of the present invention and experiment condition: drive roll and passive diameter of cylinder are 160mm, active and passive drum rotational speed is 25r/min, safety groove and centre of the drum's angle are 30 °, safety groove and cylinder two ends angle are 60 °, each 2 safety grooves of the every end of active and passive cylinder, 2 thread belts of each safety groove.
(3) compare device's parameter and experiment condition: drive roll and passive diameter of cylinder are 160mm, and active and passive drum rotational speed is 25r/min, without safety groove, without thread belt.
(4) experiment effect
Compare device: in mediating stone roller sheet process, material flows to two ends, needs manually to control to prevent that material from entering two ends power shaft, can not roll continuously, has potential safety hazard;
The present invention: material flows into safety groove Hou Zaixiang centre of the drum and flows to two ends, finally form stable state, can roll continuously, and material does not flow to second safety groove, can not flow to power shaft yet.Material is carried out to composition detection, find to adopt time of rolling that device of the present invention reaches same mixture uniformity coefficient fewer 10%～20% than compare device, working efficiency raising.After technological test, weigh explosive quality of material, loss of material of the present invention is less than 1%, compare device's loss of material 3.2%, and the present invention has improved explosive availability.With reference to GJB772A-97 method 602.1, the tablet of two groups of roller-compactions is carried out to explosion velocity test, result indifference, shows that the present invention affects explosive property thing.
Embodiment 2:
(1) according to octogen 880g, compound binding agent 90g, tetrafluoroethylene 30g, test, wherein the silicon rubber of compound binding agent and viton mass ratio are 1:3.5, after manual stirring 5min, use.
