The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is elaborated.Should be understood that, the specific embodiment described herein only is used for description and interpretation the utility model, is not limited to the utility model.
The utility model provides a kind of isolation-proof device of silo.According to embodiment of the present utility model, isolation-proof device comprises chute and is opened in a plurality of through holes on the sidewall of chute.The passage that chute glides as mixed material.The cross-sectional plane of chute can be various shape, such as but not limited to square-section, polygonal cross-section, round section, three limit circular sections or semi-circular cross-section etc.Be opened in through hole on the sidewall of chute as spillway.The material outlet that is higher than the bottom of chute when the material level of material, when perhaps the material in the chute was more, material can overflow from through hole, and can not be blocked in the chute.Should be appreciated that, because Action of Gravity Field, material preferentially overflows from the through hole of lowest order.With reference to figure 2, according to embodiment of the present utility model, the line of centers of chute extends along the direction of helix line.The overall extension trend of this helix line is to make material along the swimmingly landing of bearing of trend of this helix line.This spiral chute structure can make the path of supports for material down-sliding milder, can prevent effectively that material from producing the movement of falling object during landing in chute.And, because chute line of centers of the present utility model extends along the direction of helix line, therefore the gradient of the extension of chute in the vertical direction slows down, and the diff-H between the through hole of lowest order and the material surface therefore reduces, thereby can effectively prevent the generation of segregation phenomenon.
According to embodiment of the present utility model, chute can arrange all-in-one-piece spiral extension structure.In addition, with reference to figure 3 and Fig. 4, according to preferred embodiment of the present utility model, chute can also be arranged to comprise the in turn structure of continuous chute segmentation of a plurality of head and the tail.That is, each section chute is combined, and forms the spiral extension structure.The sectional combination structure of chute can reduce the difficulty of making and installing.According to preferred embodiment of the present utility model, chute is comprised of two sections to three sections chute segmentations.The line of centers of each chute segmentation can be helix line, also can be straight line, as long as the line of centers of the chute of the integral body that finally is combined into extends along the direction of helix line substantially.
To Fig. 7, according to embodiment of the present utility model, the shape of chute is preferably the Baltimore groove 2 of cross-sectional plane semicircular in shape with reference to figure 5.Need to prove, semicircle described here is semicircle roughly, and its implication has contained the shape that is slightly larger than or is slightly less than semicircle.The shape of through hole is preferably spill mouth 3, and this spill mouth 3 is offered along the edge of the opening part of Baltimore groove 2.This structure can be saved and be made the required material of chute, and reduces the difficulty of offering through hole.The opening of Baltimore groove 2 has the dual-side edge, and the utility model is preferably on the dual-side edge of the opening of Baltimore groove 2 and offers symmetrically spill mouth 3.And, being connected with shrouding 4 at the cell body of Baltimore groove 2, this shrouding 4 covers the opening top of a pair of symmetrical spill mouth 3.Shrouding 4 can be used as the intensity of chute cell body that reinforced rib is strengthened the opening part of spill mouth 3, and improves the integrally-built degree of stability of Baltimore groove 2.Shrouding 4 can have multiple choices with the connection mode of the cell body of Baltimore groove 2, such as but not limited to connection modes such as welding, screwings.
In addition, the utility model also provides a kind of silo 1 that stores the dry-mixed mortar finished product material, in this silo 1 above-mentioned isolation-proof device is installed.The overall extension trend of isolation-proof device in silo 1 is that extend the bottom from the top of silo 1 to silo 1, so that material can be along the bearing of trend of this chute bottom from the top landing of silo 1 to silo 1 swimmingly.
According to embodiment of the present utility model, chute is fixedly mounted on the madial wall of silo 1.Particularly, mounting bracket 6 on the inwall of silo 1, then chute are fixedly mounted on the support 6.The mode of captive joint has multiple choices, such as but not limited to, support 6 is welded on the inwall of silo 1, chute welding or use screw are connected on the support 6.According to preferred embodiment of the present utility model, between the connecting portion of the bottom of chute and support 6, brace panel 5 is set.Brace panel 5 can play the effect of protection Baltimore groove 2.Particularly when using welding manner chute to be fixedly connected on the support 6, arranging of brace panel 5 can effectively prevent from damaging in the welding process chute.
According to embodiment of the present utility model, the line of centers helical angle of chute is greater than the angle of repose of the material that stores in the silo 1, and preferred embodiment is the helical angle of line of centers of chute than the angle of repose of material large 5 ° to 10 °.In general, the angle of repose of mixed material is between 35 ° to 45 °, and the helical angle of chute line of centers of the present utility model can be chosen as between 40 ° to 55 ° accordingly.This angle can be so that material falls into silo 1 without being detained without obstruction ground from chute.
With reference to figure 3, according to embodiment of the present utility model, silo 1 comprises vertical tube part 11 and is connected to the inverted tapered portion 13 of the below of vertical tube part 11.Wherein, the bottom of chute ends at the bottom margin of vertical tube part 11.Therefore, the bottom of chute is connected with the inside face of tapered portion 13.When material falls from the bottom of chute, drop on the inside face of tapered portion 13, and be slipped to the bottom of silo 1 along the inside face of tapered portion 13.When the material level of the material in the silo 1 was higher than the bottom of chute, material overflowed from the through hole of lowest order and drops in the silo 1.No matter be in which kind of situation, can effectively prevent the generation of segregation phenomenon along the chute structure of helix line extension.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in the above-mentioned embodiment; in technical conceive scope of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
Need to prove that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment in reconcilable situation, can make up by any suitable mode.For fear of unnecessary repetition, the utility model is to the no longer separately explanation of various possible array modes.
