The specific embodiment
Embodiment one
The rotary cutting bag feeder basic structure of present embodiment is substantially extended respectively engine installation for columniform cylindrical shell 1 two ends and is driven, is supported on the horizontal hollow rotating shaft on the bearing 8 as depicted in figs. 1 and 2.Place, contiguous two ends, cylindrical shell 1 face of cylinder has respectively the opposite pocket import N1 of angular position and waste discharge mouth N2.The axis z of the geometric center lines y of cylindrical shell 1 and rotating shaft is the angle α of 10 ゜-25 ゜ (being preferably 20 °).The hollow rotating shaft center of contiguous pocket import N1 passes into gas freeing pipe N5, and shower nozzle 7 is equipped with in the inner of this gas freeing pipe, and this shower nozzle where necessary jet supplies is carried.The hollow rotating shaft of contiguous waste discharge mouth N2 leads to and radially bends 90 ° discharging opening N3, and its center passes into gas inlet pipe N4, and this air inlet pipe annular gas pipeline 5 interior be placed in cylindrical shell 1 by radial support 11 is communicated with.By seal ring 9 sealings, form airtight cavity in the cylindrical shell thereby make between gas freeing pipe N5, gas inlet pipe N4 and the hollow rotating shaft separately.The annular gas pipeline has as shown in Figure 3 towards the interval of secondary filter screen spray orifice.Cylindrical shell 1 inwall is divided into a plurality of adjacent circumferential sections by pocket import N1 between the waste discharge mouth N2, each circumferential segment is one group of cutting edge cutting knife 2 radially spaced apart respectively, contiguous cutting knife 2 angles of adjacent circumferential section are dislocatedly distributed---be last circumferential segment cutting knife and adjacent after the contiguous cutting knife of a circumferential segment not on same bus, but mutually stagger, can avoid like this leaking the slit of pocket 10 between cutting knife.Each cutting knife 2 length direction extensions and cylindrical shell 1 geometric center lines y are the angle β of 5 ゜-30 ゜ (preferred 20 °), and this angle departs from the direction of cylindrical shell geometric center lines and the opposite direction that shaft axis departs from the cylindrical shell geometric center lines, it is adaptive that so angle setting can make the flip-flop movement track of the bearing of trend of blade and pocket, effectively pocket scratched.The concrete structure of cutting knife 2 as shown in Figure 4, by the arc peak head 2-1 of radial inward projection and from arc peak head towards cylinder inboard wall gradually close junction curve cutting edge 2-2 consist of.The cutting knife of same circumferential segment has positive and negative two kinds of directions, the contiguous pocket import of the arc peak head 2-1 of (the right half cycle among Fig. 2) cutting knife 2 N1 in the same circumferential segment half cycle in the present embodiment, and the contiguous waste discharge mouth of junction curve cutting edge 2-2 N2; The contiguous waste discharge mouth of the arc peak head 2-1 of (the left half cycle among Fig. 2) cutting knife 2 N2 in other half cycle, and the contiguous pocket import of junction curve cutting edge 2-2 N1.The cutting knife that so arranges can guarantee that pocket 10 is cut in motion process.Cylindrical shell 1 interior one-level filter screen 3 and the secondary filter screen 4 of being equipped with respectively of waste discharge mouth N2 both sides, wherein the secondary filter screen is finer and close than one-level filter screen.Cylindrical shell 1 inwall between one-level filter screen 3 and the secondary filter screen 4 is equipped with spaced apart gradually to the one group of close deflecting plate 6 of hollow rotating shaft direction that is close to the waste discharge mouth.
During use, for poisonous powder material, the rotary cutting bag feeder method of operation of present embodiment comprises following basic step:
The first step, the pocket that powder material will be housed are put into cylindrical shell from the pocket import, afterwards pocket import and waste discharge mouth are closed;
Second step, startup engine installation drive cylindrical shell and rotate with desired speed, and pocket is cut by cutting knife in the upset slipping, automatically finish unpacking;
The 3rd step, continuation keep the cylindrical shell rotation, make the powder material that flows out from pocket successively see through the firsts and seconds filter screen, under the guiding of deflecting plate, progressively flow out from discharging opening, enter corresponding feed bin or reactor, finish automatic charging;
The 4th step, in the cylindrical shell rotary course, the intermittently air inlet of control gas inlet pipe is by by the annular gas pipeline filter screen being jetted, control simultaneously the degree of opening of gas freeing pipe, keeping in the cylindrical shell is malleation, thereby keeps filter screen unobstructed, and the output of auxiliary powder material;
After the 5th step, the powder material output, open the pocket import, remove pocket fragment in the cylindrical shell;
The 6th step, circulation are carried out opening the waste discharge mouth after the first to the 5th step for several times, remove the pocket fragment between the firsts and seconds filter screen.
When being used for perishable powder material, before the above first step, be filled with safe gas (for example unreactable gas, nitrogen) from gas inlet pipe first, and by the air in the gas freeing pipe discharge cylindrical shell, treat that safe gas forms malleation, the pocket that powder material will be housed is again put into cylindrical shell from the pocket import, and pocket import and waste discharge mouth are closed.In the operating process afterwards, pass into safe gas by gas inlet pipe all the time, keeping in the cylindrical shell is malleation (for 1.05-1.2 atmospheric pressure-fired gets final product).
Evidence, present embodiment have following advantage:
1, realizes the closed environment conveying, avoided the powder diffusion, significantly reduced environmental pollution and to the injury of the person.
2, set up closed conveying under the inert gas environment, can prevent effectively that material is rotten.
3, degree of automation is high, and is simple to operate, alleviated labour intensity, obviously improved work efficiency.
