Description

Technical Field

[0001] The invention relates to the technical field of material conveying, and in particular to an anti-breakage chute device for a rectangular storage silo. Background Art

[0002] Many domestic coal, coking, metallurgy, grain and other industries have built large-scale rectangular storage silos, which are used as temporary or transit storage facilities for dry bulk materials such as coal, coke, ore and grain. Conventional silo tops use belt conveyors to transport materials to various array silos, and unload materials to the top entrance of the silo by unloading trucks. The materials then fall freely to the bottom of the silo until the silo is full.

[0003] In order to ensure the designed capacity of this kind of super-large rectangular storage silo, the overall construction height of the silo is very deep, and some can reach tens of meters. This operation method has several shortcomings: First, due to the high height of the material drop and the secondary impact and crushing in the silo, a large amount of dust is generated and rises to the dust collector system on the top of the silo, resulting in an increased maintenance frequency of the dust collector system and a shortened life of wearing parts; second, when the material level in the silo is low or ultra-low, the height of the material falling from the top of the silo is very large, so when the material falls to the bottom, it will be broken or shattered due to the impact, which will affect the particle size distribution of the product and the use requirements of the downstream users of the product, or even affect the downstream use process and product price of the product. Summary of the invention

[0004] According to the technical problems raised above, a crushing-proof chute device for rectangular storage silos is provided. The present invention arranges a collection funnel, a linear chute, a guide chute, a chute structure support, etc. in combination, and can guide the materials on the top of the silo step by step to the bottom of the silo to avoid the free fall of the incoming materials with a large height difference falling into the silo bottom, reduce the dust concentration in the silo, and reduce the impact and crushing of the materials. The device is suitable for the material placement process and crushing-proof management process of large-scale rectangular storage silos.

[0005] The technical means adopted by the present invention are as follows:

[0006] An anti-crushing chute device for a rectangular storage silo, comprising: a rectangular storage silo, a collecting funnel, a linear chute, a wear-resistant liner, a guide chute, and a chute bracket;

[0007] The aggregate hopper is made of welded steel plates, its shape is determined according to the material flow characteristics, and a wear-resistant lining is attached inside;

[0008] The linear chute is made of welded steel plates, and has an L-shaped cross-section. The opening angle is determined according to the material flow characteristics. The bottom and side surfaces of the linear chute are both affixed with wear-resistant linings, and are designed to slope downward at a fixed angle, and the downward angle is determined according to the material flow characteristics.

[0009] The guide chute is made of welded steel plates, and has a U-shaped cross-section. The bottom and both sides of the guide chute are affixed with wear-resistant linings. It is a broken line type, and both sides are designed to slope downward at a fixed angle. The downward angle is determined according to the material flow characteristics. It is installed at the corner of the wall of the rectangular storage silo, and both ends are connected to the straight chute;

[0010] The chute bracket is made of profiles welded together, and has a cross-sectional shape of an inverted T-shape.

[0011] Furthermore, each section of the linear chute is provided with an external opening with different lengths, which is used to solve the free flow of materials at different material level heights in the bin and to set the overflow material flow and the material flow entering the downstream guide chute and the next section of the linear chute.

[0012] Furthermore, the zigzag design of the guide chute and the downwardly inclined slopes on both sides guide the incoming materials from the upstream linear chute to the downstream linear chute.

[0013] Furthermore, the wear-resistant lining is fixed to the contact surface between the aggregate hopper, the linear chute, the guide chute and the material by bolting.

[0014] Furthermore, the linear chute is fixed to the top of the chute bracket by installing bolts, the guide chute is fixed to the top of the chute bracket by installing bolts, and the chute bracket is fixed to the wall surface of the storage silo by pre-embedded bolts.

As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0029] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0030] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0031] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure.

Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0032] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0033] like Figures 1 to 3 As shown, the present invention provides an anti-breakage chute device for a rectangular storage silo, comprising: a rectangular storage silo 1, a collection funnel 2, a linear chute 3, a wear-resistant liner 4, a guide chute 5, and a chute bracket 6;

[0034] The aggregate hopper 2 is made of welded steel plates, and its shape is determined according to the material flow characteristics, and a wear-resistant lining plate 4 is attached inside;

[0035] The linear chute 3 is made of welded steel plates, and has an L-shaped cross-section. The opening angle is determined according to the material flow characteristics. The bottom and side surfaces of the linear chute 3 are both affixed with wear-resistant lining plates 4, and are designed to slope downward at a fixed angle, and the downward angle is determined according to the material flow characteristics.

[0036] The guide chute 5 is made of welded steel plates, and has a U-shaped cross-section. The bottom and both sides of the guide chute 5 are affixed with wear-resistant lining plates 4. The guide chute 5 is in a broken line shape, and both sides are designed to slope downward at a fixed angle. The downward angle is determined according to the material flow characteristics. It is installed at the corner of the wall of the rectangular storage silo 1, and both ends are connected to the linear chute 3.

[0037] The chute bracket 6 is made of welded profiles, and has an inverted T-shaped cross section.

[0038] The material unloaded from the top of the silo first enters the aggregate hopper 2, which is made of welded steel plates. Its shape is customized according to the material flow characteristics. The wear-resistant lining 4 inside can reduce the wear of the material on the hopper. The aggregate hopper 2 constrains the material entering the silo top so that the material can flow downward in an orderly manner to the hopper outlet.

[0039] The material flowing out from the discharge port of the aggregate hopper 2 falls into an L-shaped linear chute 3 with a downward slope at a predetermined angle. The linear chute 3 is also welded from steel plates, and its cross-sectional shape is L-shaped. The opening angle is set according to the material flow characteristics. The bottom and side surfaces of the chute are affixed with wear-resistant linings 4 to enhance wear resistance. The material continues to flow downward along the slope in the linear chute 3. During this process, some of the material will overflow from the external opening of the linear chute 3 and fall into the bin, while some of the material will continue to flow in the direction of the guide chute 5. The external openings of each section of the linear chute 3 are set at different lengths. This design can set the flow rate of the overflow material of this section of the linear chute 3, as well as the material flow rate entering the downstream guide chute 5 and the next section of the linear chute 3 according to actual needs, thereby ensuring that the material can flow freely at different material level heights in the bin, and there will be no material flow blockage. When the material reaches the guide chute 5, the material can flow freely without blocking the material flow. When the guide chute 5 is guided, the guide chute 5 plays a guiding role. The guide chute 5 is made of welded steel plates with a U-shaped cross-section. The bottom and both sides are affixed with wear-resistant lining plates 4. It is a broken line type and both sides are designed with a downward slope at a fixed angle. The downward angle is determined according to the material flow characteristics. It is mainly installed at the wall corner of the rectangular storage silo 1, and the two ends are connected with the linear chute 3. The guide chute 5 guides the incoming materials of the upstream linear chute 3, so that the materials are diverted from the linear chute 3 of one wall to the linear chute 3 of another wall, preventing the materials from directly overflowing or falling at the corner; the materials diverted by the guide chute 5 continue to enter the next linear chute 3, and repeat the above process of flowing in the linear chute 3, part of the materials overflowing and falling, and part of the materials entering the next guide chute 5, and the cycle is repeated, and the materials are guided step by step to the end of the chute or to the bottom of the silo.

[0040] The wear-resistant lining 4 is bolted and fixed on the contact surface between the aggregate hopper 2, the linear chute 3, the guide chute 5 and the material. During the operation of the equipment, the wear-resistant lining 4 effectively reduces the friction loss of the material on the various components of the chute device and extends the service life of the equipment. When the wear-resistant lining 4 is worn to a certain extent, it can be easily replaced due to its bolted fixing method, ensuring that the equipment always maintains a good operating state, reducing the downtime maintenance time caused by equipment wear, and improving production efficiency.

[0041] Furthermore, the linear chute 3 is fixed to the top of the chute bracket 6 by installing a bolt group 61, the guide chute 5 is fixed to the top of the chute bracket 6 by installing a bolt group 61, and the chute bracket 6 is fixed to the wall surface of the storage silo by an embedded bolt group 62.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
