Description
In processes such as bulk material loading and unloading, transhipment, screening, fragmentation, stacking, material falls behind when reaching on next layer height or the low level transferring adhesive tape under closed installations such as a certain height or a certain transferring adhesive tape process material blanking tube or hopper, bring fierce inertia impact and powerful induced air at material drop point place, thereby the impact, the cutting that constitute load transfer device destroy, and cause serious airborne dust simultaneously and make room air pollution, these two kinds of harm are not still had the actv. facility at home and abroad so far prevent and control.
Existing technology is: impact the destruction to carrying roller for preventing material, the carrying roller of transferring adhesive tape adopts elastic construction below drop point, but transferring adhesive tape itself is still often torn, cuts, pounds and wear; For preventing that dust-laden from inducing the excessive of air blast, be forced to install huge dust pelletizing system.
The present invention proposes at the end of material blanking tube, hopper or other closed installation the buffering flapper to be installed; allow the high material of end speed on latching buffer gas plate plate face, be forced to slow down; and make the unimpeded nothing of material stifled and make and induce air blast to be hindered substantially, thereby reach load transfer device such as protection transferring adhesive tape and reduce the purpose of inducing air blast.
The invention provides the buffering flapper of two kinds of simple in structure, safe and reliable, function admirables: latching buffer gas plate intermediate rotary shaft support type weight hammer type buffering flapper (Fig. 1) and latching buffer gas laminated spring support type weight hammer type cushion flapper (Fig. 2).
The principle of work of latching buffer gas plate intermediate rotary shaft support type weight hammer type buffering flapper (Fig. 1) is:
Material is dashed through chute (2) by inlet point (1) and drops on latching buffer gas plate (3
1), (3
2) or persist on the material of plate face, it (is weight (6) that the opposing torque that is produced with respect to rotating shaft (4) when the deadweight of material and impulsive force surpasses " no-load forward moment difference ", regulate the deadweights such as (5) of Bars bar and deduct latching buffer gas plate (3) (comprising liner plate and base plate) with respect to the forward moment that rotating shaft produced, connecting rod (12) and the deadweights such as (13) of latching buffer gas plate intermediate rotary shaft are with respect to the difference of the opposing torque that rotating shaft produced) time, material is pushed latching buffer gas plate open and is entered housing (7) after overcoming friction force such as ball bearing of main shaft, after discharging opening (10) is discharged the buffering flapper.Should regulate the position of weight on the Bars bar to obtain the best " no-load forward moment difference " before using.If " no-load forward moment difference " is bigger than normal, easy blockage phenomenon when then running into the material that surperficial moisture content is too high, character is too sticking; Otherwise too little as this value, even then the very low angle of release that also can make latching buffer gas plate of load is excessive and produce large tracts of land and eat dishes without rice or wine, allow too much induced air flow through latching buffer gas plate, increased the air blast dust emission of system.
Latching buffer gas plate (3
1) " no-load forward moment difference " be greater than latching buffer gas plate (3
2) " no-load forward moment difference ", purpose be when flow do not have normally, again especially big block of material by the time latching buffer gas plate (3
1) should be in basic closed condition.Drawing back and registration device (11) of latching buffer gas plate should be installed in addition, promptly too many, when character is too sticking when the surperficial moisture content of material, for preventing sticking stifled latching buffer gas plate can being drawn back, and help maintenance.For changing liner plate and easy to maintenancely will considering to install sealing access door (9).
The principle of work of latching buffer gas laminated spring support type weight hammer type buffering flapper (Fig. 2) is:
Weight is regulated Bars bar (5), the deadweight of weight parts such as (6) deducts latching buffer gas plate (3) with respect to the forward moment that rotating shaft (4) produces, fixedly latching buffer gas plate is with reinforcement adhesive tape (12), fixing spring holder point reinforcement adhesive tape (13), spring plank (14), the deadweight of each layer spring assembly (15) and spring bracket parts such as (16) obtains one " no-load forward moment difference " with respect to the opposing torque that rotating shaft (4) produces, and regulate the weight position and reach best " no-load forward moment difference ", make at the latching buffer gas plate that can rely on this difference will have the small amount of residual material between the departure date of stopping transport to be in closed condition.
Material is gone up or is persisted on the material of plate face towards dropping on latching buffer gas plate (3) through chute (2) by inlet point (1), when the opposing torque that is produced with respect to rotating shaft (4) when the deadweight of material and impulsive force surpasses " no-load forward moment difference " and has overcome the friction of rotating shaft ball bearing of main shaft, material is pushed latching buffer gas plate open and is entered housing (7), after discharging opening (10) is discharged the buffering flapper.
Latching buffer gas plate (3) is made up of some battens of going up lower leaf, each layer batten supported by spring assembly separately, the pressure of the required supporting of lower floor's spring is less than the upper strata, when material by the time lower floor spring distortion greater than the upper strata, its as a result latching buffer gas plate become toroidal, allow the material of chute bottom pass through in a large number, and upper strata latching buffer gas plate can effectively be placed restrictions on aperture, reach and do not allow the purpose of inducing air blast to pass through as far as possible.In addition, should install also that latching buffer gas plate draws back and room device (11) and sealing access door (9
1), (9
2).
Advantage and good effect that the present invention had are:
When bulk material in processes such as conveying, processing when material blanking tube, hopper and other closed installation fall, can prevent the impact failure of material (particularly hard ware material), foreign material (particularly metal and various sharp weapon etc.) endways behind the reload buffer flapper effectively to equipment such as transferring adhesive tapes.Drop is big more, material is hard more, cutting edge is sharp more, lance thorn is sharp more also big more to protective effect that equipment rose, thereby has saved the renewal and the cost of maintenance of transferring adhesive tape and equipment, has guaranteed safe operation.
2. after the end of closed installations such as material blanking tube, hopper is installed the buffering flapper, induce the blow rate required can reduce to original below 1/10, thereby simplify and reduced dust removal installation effectively.
3. the buffering flapper can also play certain erasure effect.
4. the latching buffer gas plate of latching buffer gas plate intermediate rotary shaft support type weight hammer type buffering flapper that is exemplified and latching buffer gas laminated spring support type weight hammer type buffering flapper all must adopt the closed form of chute outlet backing, plate face size is a bit larger tham the chute outlet size, this mode has prevented the possibility that putty gets stuck fully, guarantees the safe operation of latching buffer gas plate.
5. after the latching buffer gas plate of latching buffer gas plate intermediate rotary shaft support type weight hammer type buffering flapper adopts the intermediate rotary shaft supporting, obtain following three advantages, the force of inertia that first plate face can utilize the quality of latching buffer gas plate own to produce under fierce inhomogeneous impact force action, overcome the partly momentum of blanking by limited rotation, play the effect of first order buffering around supporting shaft; Two to be latching buffer gas plates can make the chute outlet with producing the bigger opening of angle between the latching buffer gas plate face after supporting shaft is done limited rotation for it, helps discharging bulk materials and minimizing and induce the air blast inleakage; It three is when irregular wear appears in chute outlet and latching buffer gas plate plate face, relies on the plate face to make the closing sealing between chute exit face and the latching buffer gas plate plate face obtain nature and compensate around the limited rotation of supporting shaft.
The bar shaped latching buffer gas plate of latching buffer gas laminated spring support type weight hammer type buffering flapper by spring assembly supporting separately after, can obtain following five advantages: the first is after having spring-loaded between spring bracket and the latching buffer gas plate, the force of inertia that can utilize sole masies such as latching buffer gas plate and each layer reinforcement adhesive tape, spring plank to produce is made first order buffer action efficiently to the impact of material, sort buffer is not only in vertical generation, and in horizontal generation; Its two be since the pressure of the required supporting of lower floor's spring less than the upper strata, material by the time lower floor spring distortion greater than the upper strata, its result under forming between chute exit face and the latching buffer gas plate face wide narrow toroidal, and that this shape helps most is anti-blocking, discharging and lock gas; Its three be every block buffering lock gas batten all by separately spring assembly supporting, between chute exit face and latching buffer gas plate face, have the bigger ability of freely coincideing, help closing leak free and compensate naturally; It four is that adopt after the spring loaded first order buffering can more effective noise reduction; It five is that the inertia of spring is little, makes the action of latching buffer gas plate more flexible and responsive.
7. the second stage buffer action of two kinds of buffering flappers is absorbed by the moment of inertia of weight Bars bar, more safe and reliable, when the plate face has the moment of wet feed when bonding latching buffer gas plate side to strengthen naturally and increases aperture, binding material is subjected to dash to graduate into tangentially to be dashed by forward simultaneously, not anti-the cutting and sizing is withstand voltage, can not continuation be piled height so sizing constantly cuts, thereby prevent the Tower Bridge of material and obstruction comprehensively, so this buffering flapper can not bring the factor of putty.
8. the buffering flapper has been considered also that discharge gate stagger angle short tube, access door, latching buffer gas plate draw back and registration device etc. is convenient to keep in repair and the facility of operation management.
