Description

Technical Field

[0001] The utility model relates to the field of material storage equipment, in particular to a material discharging mechanism of a mud storage hopper. Background Art

[0002] As a common material storage device, the slide silo is widely used in the storage of viscous materials such as sludge. The slide silo is usually equipped with a movable slide at the bottom of the silo, and the reciprocating movement of the slide promotes the movement of the internal material toward the discharge port at the bottom.

[0003] At present, for the setting of discharging at the bottom of the silo, there are many sludge storage silos disclosed in application number 202123394581.6, in which a discharging screw is arranged at the bottom discharge port of the silo to transport and discharge the material discharged from the discharge port through one end of the discharging screw.

[0004] When storing sludge in this type of existing storage silo, the sludge at the bottom is often easy to form clumps after being squeezed. When it is transported horizontally in the discharge screw, some clumps are not easily destroyed by the conveying screw, and the clumps are easy to further form clumps during the movement and transportation of the conveying screw. As a result, after the sludge is discharged, multiple clumps will appear in the sludge. In some working conditions where the sludge is transported through pipelines, the clumps will easily flow slowly in the pipelines and be easily blocked.

[0005] Therefore, it is urgent to improve the existing mud storage bucket. Utility Model Content

[0029] In the present utility model, unless otherwise clearly specified and limited, the first feature "above" or "below" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0030] In the present utility model, if Figure 1-3 As shown, a discharging mechanism of a mud storage hopper is provided, including a silo 1, the bottom wall of the silo 1 is provided with a discharging port 2 extending along a first direction, the discharging mechanism also includes a spiral conveying assembly arranged on the bottom wall of the discharging port 2, the spiral conveying assembly includes a bottom shell 3, a first screw 4 and a second screw 5 arranged on the bottom shell 3, and a driving member 6 for driving the first screw 4 and the second screw 5 to rotate, the bottom shell 3 and the bottom wall of the silo 1 are enclosed to form a material guide trough, the first screw 4 and the second screw 5 extend along the first direction, and the first screw 4 and the second screw 5 are arranged at intervals along a second direction perpendicular to the first direction, a material twisting gap 7 is formed between the first screw 4 and the second screw 5, and the vertical projection of the material twisting gap 7 is located in the discharging port 2, and a discharging hole 11 is provided at the bottom of the bottom shell 3, wherein the spiral conveying assembly is arranged so that when the first screw 4 and the second screw 5 push the material toward the discharging hole 11, the material in the material twisting gap 7 is pushed in a direction away from the material twisting gap 7.

[0031] When the material bin 1 is discharged, the discharging mechanism of the utility model rotates the first screw 4 and the second screw 5, so that the material in the twisting gap 7 is stirred by the first screw 4 and the second screw 5 in opposite directions and then moves toward the discharging hole 11, and then the first screw 4 and the second screw 5 cooperate to tear and crush the material and then move it, so as to reduce the occurrence of the material agglomeration. The problems existing in the prior art are effectively solved.

[0032] exist Figure 2 In order to better illustrate the structural relationship, the first connecting rod, the second connecting rod and the discharge hole 11 are all drawn with dotted lines.

[0033] In a preferred embodiment, regarding the arrangement of the first screw 4 and the second screw 5 of this practice, to be more specific, the rotation directions of the first screw 4 and the second screw 5 are opposite.

[0034] Preferably, a further optimized setting of the present invention is that the width of the twisted material gap 7 is greater than or equal to 3 cm and less than or equal to 5 cm.

[0035] By controlling the twisting gap 7 in the utility model, there is a sufficient gap between the first screw 4 and the second screw 5, so that when the material falls from the upper side of the twisting gap 7, there is enough space for the material to fall, and when the material on the lower side of the first screw 4 and the second screw 5 turns upward, the material is prevented from being compacted in the twisting gap 7.

[0036] Furthermore, the width of the cutter gap 7 is controlled to be less than or equal to 5 cm to prevent the material from stagnating in the cutter gap 7 .

[0037] The width of the strand gap 7 refers to the gap width between the edges of the first screw 4 and the second screw 5 in vertical projection.

[0038] In the illustrated embodiment, a further optimized configuration is that the vertical projection of the side of the first screw away from the twisting gap 7 is located outside the discharge port 2;

[0039] The vertical projection of the side of the second screw facing away from the twisting gap 7 is located outside the discharge port 2 .

[0040] As shown in the figure, the material discharged from the discharge port 2 is located as a whole in the middle area after the first screw 4 and the second screw 5 are combined. The fallen material is quickly flipped and pushed outward by the first screw 4 and the second screw 5 to quickly reduce the pressure between the materials at the discharge port 2, which is beneficial for the first screw 4 and the second screw 5 to tear and crush the material outward.

[0041] In the illustrated embodiment, more specifically, as shown in the figure, the discharge hole 11 is located in the middle section of the bottom shell 3, and the first screw 4 and the second screw 5 are respectively disposed on both sides of the discharge hole 11.

[0042] As shown in the figure, this can further reduce the moving distance of the material in the bottom shell 3 and further reduce the possibility of the material being compacted during the transportation process.

[0043] In the illustrated embodiment, more specifically, as shown in the figure, the first screw rods 4 on both sides of the discharge hole 11 are integrally connected by a first connecting rod 9.

[0044] The second screw rods 5 on both sides of the discharge hole 11 are integrally connected via a second connecting rod 10 .

[0045] As shown in the figure, the two first screws 4 can be connected and driven as one, and the two second screws 5 can be connected and driven as one, so that the overall spiral conveying structure is simple. Moreover, the first connecting rod 9 and the second connecting rod 10 are located at the discharge hole 11 to facilitate the discharge of materials.

[0046] In the illustrated embodiment, a further optimized arrangement is that a receiving plate 8 is provided on the bottom wall of the silo 1 in the middle section of the discharge port 2 , and the receiving plate 8 is located on the upper side of the first connecting rod 9 and the second connecting rod 10 .

[0047] As shown in the figure, by arranging the material receiving plate 8 on the upper side of the first connecting rod 9 and the second connecting rod 10, it is possible to prevent the material from falling directly to the discharge hole 11, so that the material in the silo 1 is stirred and broken by the first screw 4 and the second screw 5 and then discharged from the discharge hole 11, so that the material is loose when discharged. It is also possible to prevent the material on the upper side of the discharge hole 11 from mixing the material transported by the first screw 4 and the second screw 5 to the position of the first connecting rod 9 and the second connecting rod 10 into a mass, further making the material loose when discharged.

[0048] The material on the upper side of the material receiving plate 8 is discharged by the reciprocating movement of the slide.

[0049] As a selection, the utility model is further optimized in that the receiving plate 8 is arranged to be hollowed out. In this way, the material on the upper side of the receiving plate 8 can directly fall through the hollowed-out receiving plate 8 to improve the discharge efficiency, and the material of the mass can also be prevented from falling directly.

[0050] As a preferred embodiment, the utility model is further optimized in that the size of the hollow hole of the material receiving plate is greater than or equal to 3 cm and less than or equal to 5 cm. By controlling the size of the hollow hole, the hollow hole is prevented from being blocked due to the small hole diameter, and the problem of the mass material falling directly due to the large hollow hole can also be prevented.

[0051] In the illustrated embodiment, more specifically, as shown in the figure, the first screw rod 4 and the second screw rod 5 on both sides of the discharge hole 11 extend to the lower side of the receiving plate 8 respectively.

[0052] In this way, the materials falling from the discharge port 2 are stirred and transported by the first screw 4 and the second screw 5, further improving the looseness of the materials after being discharged from the discharge hole 11.

[0053] In the present invention, the drive member 6 is preferably provided with gears on the first screw 4 and the second screw 5, and a single motor drives the two gears to rotate through a gear transmission mechanism. Alternatively, two separate motors are used to drive the first screw 4 and the second screw 5 to rotate respectively.

[0054] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0055] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
