Detailed description of the invention
In order to enable the inspector of Patent Office especially the public clearly understand technical spirit of the present invention and beneficial effect, applicant will elaborate below by way of example, but be not all the restriction to the present invention program to the description of embodiment, any conceive according to the present invention done be only pro forma but not substantial equivalent transformation and all should be considered as technical scheme category of the present invention.
Refer to Fig. 1 and Fig. 2, give vibration box body 1, the case diapire 11 of this vibration box body 1 is fixed with a discharging opening 111, and be respectively fixed with a permanent seat 112 in the side and opposite side corresponding to discharging opening 111, that is permanent seat 112 has a pair, and parallel.
Give powder automatic output mechanism 2, this powder automatic output mechanism 2 preferably but not the structure be definitely limited to is as follows: comprise motor 21, retarder 22 and blade-type pump 23, the blade-type pump inlet point 231 of blade-type pump 23 is fixed by screw and aforesaid discharging opening 111, the blade-type pump discharging opening 232 of blade-type pump 23 is connected with the flexible transition sealing shroud 5 that will illustrate below, the pump shaft 233 of blade-type pump 23 is in transmission connection with the reducer output shaft of retarder 22, and on pump shaft 233, be configured with blade 2331, blade 2331 corresponds to blade-type pump and enters, discharging opening 231, between 232, retarder 22 is fixed on speed reducer base 221, and speed reducer base 221 and blade-type pump 23 are fixed, motor 21 is fixed with retarder 22, and be in transmission connection with retarder 22.
The quantity of one group of seal cover board lift action cylinder 3 has four in the present embodiment, the rectangular body of geometric configuration due to seal cover board 4, more precisely in square, therefore four seal cover board lift action cylinders 3 are distributed in four bights of seal cover board 4, every two seal cover board lift action cylinders 3 share one piece of cylinder body fixed mount 33, so cylinder body fixed mount 33 has parallel a pair, the cylinder body of each seal cover board lift action cylinder 3 is fixed by cylinder body fix screw 32 and cylinder body fixed mount 33, and cylinder body fixed mount 33 adopts fixed mount screw 331 and aforesaid permanent seat 112 to fix, the acting cylinder post 31 of each seal cover board lift action cylinder 3 is fixed by cylinder post permanent seat 311 and seal cover board 4.
Aforesaid seal cover board lift action cylinder 3 adopts cylinder, but, if use oil cylinder, so should equivalence be considered as.
A seal cover board discharge opening 41 is offered at the central part of above mentioned seal cover board 4, and preferably use adhesives and adhesion agent or screw to be fixed with a packing seal 42 at seal cover board 4 back to the side of the case diapire 11 of aforementioned vibration box body 1, and equally preferably use in the position, edge of sealing pad 42 adhesion agent or screw cementation to have press strip 421.Packing seal 42 preferably uses rubber, and press strip 421 is rubber strip.
The one end of the flexible transition sealing shroud 5 that preferred use rubber coating is filled the post of and graphic upper end are by means of upper trim ring 51 and fix with trim ring fix screw 511 and the flange on blade-type pump discharging opening 232.The other end of flexible transition sealing shroud 5 and graphic lower end are with lower clamping ring fix screw 521 fixing at position and the seal cover board 4 of the edge corresponding to seal cover board discharge opening 41 by means of downforce circle 52.According to common practise, the length of flexible transition sealing shroud 5 is reserved with the surplus being enough to compensating action cylinder 31 maximal dilation, and that is flexible transition sealing shroud 5 has telescopic redundancy section.
In order to scoop out the powder alleged by the primary raw material mixture and this patent that are exported by aforesaid powder automatic output mechanism 2, and in order to ensure coordinate friendly with manganese-zinc ferrite powder output unit of the present invention, therefore recommend the rational in infrastructure manganese-zinc ferrite powder material-receiving device aiming at manganese-zinc ferrite powder output unit " customization of amount body ".
Above mentioned manganese-zinc ferrite powder material-receiving device comprises splicing ladder 6 and a receiving hopper 7, splicing ladder 6 is the fiame-like construction of surrounding and bottom hollow out, and be fixed with a top board 61 in the welded top of this splicing ladder 6, a material receiving port 611 is offered at the middle section of top board 61, and be configured with a sealing stack limit 6111 being raised in the surface of top board 61 enclosed around the position, edge of material receiving port 611, sealing stack limit 6111 is corresponding with aforesaid press strip 421.One group of road wheel 62 is respectively provided with in four bights of the bottom of splicing ladder 6.Receiving hopper 7 is fixed in splicing ladder 6, and the top of this receiving hopper 7 is corresponding with aforesaid material receiving port 611 and communicate.According to general knowledge, top and material receiving port 611 tight weld of receiving hopper 7 are integrated.An emptying door 71 is equipped with pluggable mode in the bottom of receiving hopper 7.
Preferably, a handle 612 can be fixed on top board 61 and the correspondence position of both sides is each, hold when moving splicing ladder 6 for operator by a pair handle and pinch.Preferably, aforesaid emptying door 71 is fixed with a handle 711, plays the effect of convenient plug emptying door 71 by this handle 711.
When splicing 7 is in-built enter primary raw material mixture after, and moving to subsequent processing with splicing ladder 6 and be promoted to after on blowing platform, pull-out emptying door 71, just can put the primary raw material mixture in receiving hopper 7 and remove.
Applicant's composition graphs 1 and Fig. 2 sketch application of the present invention, and when the vibration box body 1 being installed on the vibrating ball-mill on vibration block 12 is in running order, the acting cylinder post 31 of one group of seal cover board lift action cylinder 3 is positioned at cylinder body.But, when will by discharging opening 111 by vibration box body 1 complete the primary raw material mixture after vibration release time, so splicing ladder 6 moved the position to the below corresponding to seal cover board 4 by operator, then to be worked or out-of-work acting cylinder master cock 34(Fig. 2 shows to for controlling seal cover board lift action cylinder 3 by workman) operation, the acting cylinder post 31 of one group of seal cover board lift action cylinder 3 stretches simultaneously outside cylinder body, because acting cylinder post 31 is fixed by cylinder post permanent seat 311 and seal cover board 4, therefore the direction displacement of seal cover board 4 towards receiving hopper 7 is promoted by acting cylinder post 31, until the press strip 421 on the packing seal 42 of seal cover board 4 reliably closes with sealing stack limit 6111.Then by the operation to electric controling switch, motor 21 is worked, retarder 22 is driven by motor 21, and slowed down by retarder 22, and then the pump shaft 233 of blade-type pump 23 is driven by retarder 22, under the rotation of pump shaft 233, be with moving blade 2331, thus primary raw material mixture is entered in receiving hopper 7 through blade-type pump inlet point 231, blade-type pump discharging opening 232, flexible transition sealing shroud 5, seal cover board discharge opening 41 and material receiving port 611 successively by discharging opening 111.Blowing is complete or when empty receiving hopper 7 need be changed in midway, so operates according to aforesaid reverse order.
As shown in the above description, when blowing, sealing stack limit 6111 due to material receiving port 611 is controlled by seal cover board 4 positiver sealing of the acting cylinder post 31 of seal cover board lift action cylinder 3, namely sealed by press strip 421, therefore there will not be the phenomenon that dust is more climing, cash the technique effect described in applicant's technique effect hurdle all sidedly.
