Description

Technical Field

[0001] The invention relates to the technical field of silo construction, and in particular to a silo and a silo construction method. Background Art

[0002] A silo is a facility used to store bulk materials, such as coal, salt or grain, and generally includes a cylinder and a hopper at the bottom of the cylinder; a top plate is provided at the upper end of the cylinder to seal the opening, a bottom plate is provided at the lower end, and a discharge port is provided on the bottom plate; the hopper has a large end and a small end, wherein the large end is at the top and docked with the discharge port, and the small end is at the bottom, which is used to unload the materials in the cylinder; since the hopper needs to bear the load generated by the materials above it, for the stability of the funnel, some silos will narrow the lower end of the discharge port (the end away from the top plate), and make the diameter of the large end of the funnel larger than the diameter of the lower end of the discharge port, and clamp the large end of the funnel above the lower end of the discharge port, so as to firmly support the funnel on the lower part of the cylinder through the side wall of the discharge port; therefore, the installation of this funnel needs to be hoisted from the top of the discharge port to the bottom, or the funnel needs to be divided into multiple pieces and then assembled inside the silo.

[0003] In some existing silos, for example, in a silo funnel structure disclosed in publication number CN110453954A, an inclined wall is also provided at the lower part of the cylinder, one end of the inclined wall along the radial direction of the cylinder is connected to the inner wall of the cylinder, and the other end is connected to the inclined surface of the funnel, so as to unload all the materials in the silo as much as possible. However, this inclined wall will occupy a considerable part of the space at the lower part of the silo, resulting in limited hoisting or assembly space for the funnel; at the same time, the inclined wall is often made of lightweight materials and lacks a horizontal working plane, and cannot be used to support temporary components required for hoisting or assembling the funnel, such as hoisting components or working platforms, which will further increase the difficulty of installing the funnel, and then slow down the construction progress of the entire silo. Therefore, it is necessary to develop a new type of silo structure and corresponding construction method. Summary of the invention

[0004] The purpose of the present invention is to overcome the technical problem in the prior art that the funnel needs to be hoisted or assembled in a limited space above the bottom plate, which makes the installation of the funnel difficult, because the size of the large end of the funnel is larger than the size of the lower end of the discharge port, and to provide a silo and a silo construction method.

[0005] In a first aspect, the present invention provides a silo, comprising a cylinder and a funnel; a bottom plate is provided at one end of the cylinder, and a discharge port is provided on the bottom plate; the funnel comprises a large end and a small end, and the large end of the funnel is clamped at the discharge port;

[0006] The side wall of the funnel is provided with at least one vertical seam, one end of the vertical seam is connected to the large end of the funnel, and the other end of the vertical seam extends toward the small end of the funnel along the axis direction of the funnel;

[0007] The side wall of the funnel is also connected with a first hanging component, and at least two first hanging components are respectively distributed on both sides of the vertical seam along the circumference of the funnel.

[0008] The silo of the present invention is provided with a vertical seam on the funnel, and at least one first hanging component is respectively provided on both sides of the vertical seam; when installing the funnel, a cable is connected between the first hanging components on both sides of the vertical seam and tightened to close the large end of the funnel (the side plates of the funnel on both sides of the vertical seam will partially overlap at the vertical seam, thereby reducing the diameter of the large end of the funnel); when the diameter of the large end of the funnel is reduced to be smaller than the diameter of the lower end of the discharge port, the funnel can be directly inserted into the discharge port from bottom to top. Therefore, the present invention can directly perform the installation operation of the funnel and the pre-installation preparation work (such as moving, assembling and welding of the funnel parts) in a more spacious space below the bottom plate (outside the cylinder), without having to perform the installation operation of the funnel and the pre-installation preparation work in the limited space above the bottom plate (inside the cylinder) as in the prior art, thereby greatly reducing the difficulty of installing the funnel, and improving the installation efficiency of the funnel and the overall construction efficiency of the silo.

[0009] Preferably, a pre-buried steel plate is further provided on one side of the discharge port facing the side wall of the funnel, and the large end of the funnel is connected to the pre-buried steel plate.

[0010] This solution can facilitate operators to connect the metal funnel and the concrete bottom plate to each other by welding or bolting.

[0011] Preferably, it further comprises a second hanging member, one end of which is connected to the embedded steel plate, and the other end of which extends toward the center of the cylinder along the radial direction of the cylinder.

[0012] This solution sets a second lifting component on the embedded steel plate, which can facilitate the staff to use the second lifting component to lift objects located below the bottom plate, so as to speed up the work efficiency of the funnel installation operation and the preparatory work before installation.

[0013] Preferably, an inclined wall is further provided in the cylinder, which is arranged around the discharge port, one end of the inclined wall along the radial direction of the cylinder is connected to the inner wall of the cylinder, and the other end of the inclined wall along the radial direction of the cylinder is connected to the inclined surface of the funnel.

[0014] This solution can guide all the materials in the cylinder into the funnel as much as possible, thereby improving the maximum utilization rate of the materials in the cylinder.

[0015] Preferably, the funnel is divided into at least two sections along its axial direction.

[0016] This solution divides the funnel into multiple segments with smaller sizes and weights, which can reduce the difficulty of producing, transporting and hoisting the funnel.

[0017] Preferably, when two adjacent segments have vertical seams, the positions of the vertical seams on the two adjacent segments along the circumference of the funnel are staggered with each other.

[0018] This solution can prevent the vertical joints on two adjacent segments from forming a continuous weak surface, thereby causing the funnel to break along the vertical joint during operation.

[0019] Preferably, the side wall of the funnel is also provided with a plug welding hole, and the plug welding hole is arranged close to the large end of the funnel.

[0020] This solution can facilitate the staff to weld the funnel to the side wall of the discharge port by plug welding, and the plug welding hole can increase the connection area between the side wall of the funnel and the corresponding structure on the discharge port, thereby ensuring a reliable connection between the funnel and the bottom plate.

[0021] Preferably, a third hanging component is also connected to the inner side wall of the funnel, and at least two third hanging components are distributed at intervals along the circumference of the funnel.

[0022] This solution can facilitate workers to lift the position of the funnel through the third lifting component on the funnel, and because the third lifting components are distributed at intervals along the circumference of the funnel, this solution also has good stability when lifting the funnel, which can reduce the risk of the funnel overturning.

[0023] Preferably, a construction platform is also connected to the inner wall of the funnel.

[0024] This solution can facilitate the workers to carry out the installation operation of the funnel and the pre-installation preparation work on the inner side of the funnel, and because the construction platform is located on the inner side of the funnel, the construction platform will not hinder the operation of the large end of the funnel passing through the lower end of the discharge port.

[0025] In a second aspect, the present invention provides a silo construction method, which is applied to a silo of the present invention and comprises the following steps:

[0026] S1, construction cylinder and base plate;

[0027] S2, move the funnel to the bottom of the bottom plate, connect the cables between the first hanging components on both sides of the vertical joint, and tighten the cables until the diameter of the large end of the funnel is smaller than the diameter of the lower end of the discharge port;

[0028] S3, move the funnel upward until the large end of the funnel passes through the lower end of the discharge port; loosen the cable until the diameter of the large end of the funnel is restored to be larger than the diameter of the lower end of the discharge port;

[0029] S4. Fit the vertical seams to connect the funnel to the bottom plate.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The present invention provides a silo. By arranging a vertical joint on the funnel and arranging at least one first hanging member on both sides of the vertical joint, the large end of the funnel can be closed when the funnel is installed, so that the funnel can be inserted into the discharge port from bottom to top, without having to perform the installation operation of the funnel and the preparatory work before installation in the limited space above the bottom plate as in the prior art, thereby greatly reducing the difficulty of installing the funnel, and improving the installation efficiency of the funnel and the overall construction efficiency of the silo.

[0032] 2. The construction method of the silo of the present invention adopts a working sequence of first closing the large end of the funnel by using the vertical joint and the first lifting component, and then installing the funnel from bottom to top, thereby avoiding the installation operation of the funnel and the preparatory work before installation in the limited space above the bottom plate, having a smaller construction difficulty, and being conducive to improving the installation speed of the funnel and the overall construction efficiency of the silo.

[0059] Example 1

[0060] like Figures 1 to 16 As shown, a silo comprises a cylinder body 1 and a funnel 2.

[0061] The specific design of the cylinder 1 can refer to the prior art, for example Figure 1 and Fig. 9 As shown, a top plate 11 is arranged at one end of the cylinder 1, and a bottom plate 12 is arranged at the other end; a discharge port is arranged on the bottom plate 12, and the lower end of the discharge port is closed, that is, the diameter of the lower end of the discharge port is smaller than the diameter of the upper end of the discharge port.

[0062] The funnel 2 is made of metal, one end of which is a large end and the other end is a small end, for example Figure 3 As shown, if the diameter of the large end of the funnel 2 is Ds, the diameter of the upper end of the discharge port is Dt, and the diameter of the lower end of the discharge port is Db, then Dt>Ds>Db, so that the large end of the funnel 2 can be clamped in the discharge port, and the inclination angle of the side wall of the funnel 2 relative to the horizontal plane matches the inclination angle of the side wall of the discharge port, so that after the large end of the funnel 2 is clamped into the discharge port, it can fit firmly with the side wall of the funnel 2.

[0063] The side wall of the funnel 2 is provided with at least one vertical seam 201, one end of the vertical seam 201 is connected to the large end of the funnel 2; the other end of the vertical seam 201 extends toward the small end of the funnel 2 along the axial direction of the funnel 2 (parallel to the height direction of the cylinder 1), and can either extend all the way to the small end of the funnel 2 (that is, the vertical seam 201 is arranged along the axial direction of the funnel 2 relative to the length of the funnel 2), or be interrupted before reaching the small end of the funnel 2 (that is, the length of the vertical seam 201 along the axial direction of the funnel 2 is less than the total length of the funnel 2), and the specific line shape of the vertical seam 201 includes but is not limited to a straight line, a broken line or an arc, as long as the vertical seam 201 can be used to achieve the closing of the large end of the funnel 2.

[0064] The side wall of the funnel 2 is also connected with a first hanging member 202, and at least two first hanging members 202 are respectively distributed on both sides of the vertical seam 201 along the circumference of the funnel 2. The first hanging member 202 is used to connect the cable 4, so that the two ends of the cable 4 are respectively connected to the side walls of the funnel 2 on both sides of the vertical seam 201, so that the side walls of the funnel 2 on both sides of the vertical seam 201 can be moved closer or farther from each other by retracting and releasing the cable 4, thereby changing the diameter of the large end of the funnel 2; the specific structural form of the first hanging member 202 includes but is not limited to a lifting ear, a lifting ring, a hanging pin or a hook, for example Fig.15 As shown, the perforated ear plate can be directly used as the first hanging component 202; the cable 4 includes but is not limited to a steel wire rope or an iron chain.

[0065] It should be noted that the vertical seam 201 of the side wall of the funnel 2 needs to remain disconnected before the funnel 2 is stuck in the discharge port and cannot be spliced ​​(for example, the steel plates of the funnel 2 on both sides of the vertical seam 201 are welded to each other or connected by threaded connectors), otherwise the vertical seam 201 will lose the ability to close the funnel 2.

[0066] In an optional embodiment, the side of the discharge port facing the side wall of the funnel 2 is also covered with an embedded steel plate 121, and the large end of the funnel 2 is connected to the embedded steel plate 121. The specific connection method includes but is not limited to welding connection or threaded connection.

[0067] In the above embodiment, anchor bars are also provided on the side of the embedded steel plate 121 away from the side wall of the funnel 2, and the anchor bars are inserted into the bottom plate 12 to ensure a reliable connection between the embedded steel plate 121 and the bottom plate 12 to prevent the embedded steel plate 121 from falling off under the action of external force.

[0068] In an optional embodiment, a second lifting member 122 is further included, one end of which is connected to the embedded steel plate 121, and the other end of which extends radially toward the center of the cylinder 1, so that the staff can conveniently hang the sling 3 from the second lifting member 122 to lift the object. The specific structural form of the second lifting member 122 includes but is not limited to a lifting lug, a lifting ring, a hanging pin or a hook.

[0069] In an optional embodiment, when the embedded steel plate 121 has sufficient surface area for welding the second lifting component 122, the second lifting component 122 can directly adopt a perforated ear plate, but the difference between it and the first lifting component 202 is that the second lifting component 122 needs to extend toward the center of the cylinder 1 to facilitate the lowering of the sling 3 below the bottom plate 12.

[0070] In an optional embodiment, if Fig.16 The second hanging member 122 shown in the figure comprises a T-shaped steel plate arranged along the radial direction of the cylinder 1 and a horizontal steel plate connected to the bottom surface of the T-shaped steel plate. The bottom surface of the horizontal steel plate is provided with three legs for connecting with the embedded steel plate 121. A stiffening rib is also provided between the side surface of the T-shaped steel plate and the upper surface of the horizontal steel plate to increase the rigidity of the second hanging member 122. The connection area between the second hanging member 122 and the embedded steel plate 121 is small, and it is suitable for the case where the available surface area of ​​the embedded steel plate 121 is small.

[0071] In the above embodiment, at least two second hanging components 122 are spaced apart and distributed along the circumference of the discharge port.

[0072] In the above embodiment, the side wall of the funnel 2 is also provided with a vertical through groove, one end of the vertical through groove is connected to the large end of the funnel 2, and the other end extends toward the small end of the funnel 2 along the axial direction of the funnel 2, and the number, size and position of the vertical through grooves are matched with the corresponding parameters of the second hanging component 122. When the funnel 2 moves upward, the second hanging component 122 can be inserted into the vertical through groove, thereby avoiding interference between the second hanging component 122 and the funnel 2 and having a certain limiting effect on the funnel 2.

[0073] In an optional embodiment, an inclined wall 13 is further provided in the cylinder 1, and the inclined wall 13 is arranged around the discharge port. One end of the inclined wall 13 along the radial direction of the cylinder 1 is connected to the inner wall of the cylinder 1, and the other end of the inclined wall 13 along the radial direction of the cylinder 1 is connected to the inclined surface of the funnel 2.

[0074] In an optional embodiment, the funnel 2 is divided into at least two segments 20 along its axial direction, and two adjacent segments 20 are connected by welding or by threaded connectors. Figure 4 As shown, the funnel 2 is divided into four segments 20 along its axial direction, wherein the two segments 20 near the large end are provided with vertical seams 201, while the two segments 20 near the small end do not need to be provided with vertical seams 201; the specific size of the segment 20 is determined according to the actual transportation and lifting capacity.

[0075] In an optional embodiment, when two adjacent segments 20 both have vertical seams 201 , the positions of the vertical seams 201 on the two adjacent segments 20 along the circumference of the funnel 2 are staggered with each other.

[0076] It should be noted that in order to ensure that the vertical seams 201 of two adjacent segments 20 are continuous after the segments 20 are connected to each other, the seams of the segments 20 between the two adjacent vertical seams 201 are not spliced ​​to avoid the difficulty in closing the funnel 2 due to the discontinuity of the vertical seams 201, for example Figure 7 As shown in the figure, numbers G1 and G2 represent the vertical seams 201 on the two segments 20 respectively, and number G3 represents the portion of the horizontal seam between the two segments 20 located between the two vertical seams 201. Before the funnel 2 is stuck in the discharge port, not only the vertical seams 201G1 and the vertical seams 201G2 need to be kept disconnected, but the horizontal seam G3 also needs to be kept disconnected.

[0077] In an optional embodiment, the side wall of the funnel 2 is further provided with a plug welding hole 204, and the plug welding hole 204 is provided near the large end of the funnel 2. Figure 3 As shown, the plug welding holes 204 can be arranged in at least two rows along the axial direction of the funnel 2 to further increase the welding area between the side wall of the funnel 2 and the embedded steel plate 121 .

[0078] In an optional embodiment, a third hoisting member 203 is further connected to the inner side wall of the funnel 2, and at least two third hoisting members 203 are distributed at intervals along the circumference of the funnel 2. The third hoisting member 203 is used to connect the cable 4 to facilitate the lifting of the funnel 2. Its specific structural form is the same as the first hoisting member 202, including but not limited to a lifting ear, a lifting ring, a hanging pin or a hook. The difference is that the first hoisting member 202 is used to connect the cable 4 horizontally (perpendicular to the axial direction of the funnel 2), and the second hoisting member 122 is used to connect the sling 3 vertically (parallel to the axial direction of the funnel 2). Therefore, the installation directions of the first hoisting member 202 and the second hoisting member 122 will be different, and the specific installation angle difference depends on the actual hoisting situation and the setting of the vertical joint 201.

[0079] In an optional embodiment, a construction platform 205 is also connected to the inner wall of the funnel 2. Fig.14 As shown, round steel can be used to build a stepped construction platform 205 on the inner wall of the funnel 2 to facilitate the workers to assemble, weld and close the funnel 2 on the inner wall of the funnel 2.

[0080] In an optional embodiment, a winch 5 is also provided on the top plate 11 of the cylinder 1, and the sling 3 of the winch 5 is lowered from the hole in the center of the top plate 11 to the bottom of the bottom plate 12 to assist in lifting or pulling the funnel 2 components; a number of pulley assemblies can be arranged at intervals along the length direction of the sling 3 to change the path of the sling 3 to adapt to different installation spaces or pulling requirements.

[0081] In an optional embodiment, a sling is further included, one end of which is connected to the top plate 11, and the other end is lowered to the height of the discharge port of the bottom plate 12, and is used as a hanging point for a safety belt of personnel when hoisting the funnel 2.

[0082] Example 2

[0083] like Figures 10 to 13 As shown, a silo construction method, applied to a silo in Example 1, comprises the following steps:

[0084] S1, construct the cylinder 1 and the top plate 11, bottom plate 12 and the discharge port on the bottom plate 12 in the cylinder 1. If the silo also includes embedded steel plates 121 and inclined walls 13, the embedded steel plates 121 and the inclined walls 13 are also constructed in this step.

[0085] S2, such as Fig.10 As shown, the funnel 2 is moved to the bottom of the bottom plate 12, and the preparation work before the installation of the funnel 2 is carried out under the bottom plate 12, such as assembling and welding the segments 20 and other auxiliary components, and then Figure 7 and Figure 8As shown, the cable 4 is connected between the first hanging components 202 on both sides of the vertical joint 201 and tightened until the diameter of the large end of the funnel 2 is smaller than the diameter of the lower end of the discharge port.

[0086] In the above embodiment, the winch 5 can be used to pull the components of the funnel 2 from the outside of the cylinder 1 to the bottom of the bottom plate 12.

[0087] In the above embodiment, the cable 4 can be an electric hoist or a manual hoist.

[0088] In the above embodiment, when performing the preparatory work before installing the funnel 2, such as welding of the funnel 2 parts, the following method can be used: Fig.10 As shown, the sling 3 is connected between the third slinging member 203 of the funnel 2 and the second slinging member 122 on the embedded steel plate 121 and tightened to prevent the funnel 2 from accidentally tipping over.

[0089] In the above embodiment, before the preparatory work for installing the funnel 2 is performed, a temporary construction platform 205 is provided on the inner wall of the funnel 2 .

[0090] S3, such as Fig.11 As shown, the funnel 2 is moved upward until the large end of the funnel 2 passes through the lower end of the discharge port and reaches a specified elevation; the pull rope 4 is loosened until the diameter of the large end of the funnel 2 is restored to be larger than the diameter of the lower end of the discharge port.

[0091] In the above embodiment, the specific method of moving the funnel 2 includes but is not limited to setting a lifting mechanism at the bottom of the funnel 2, or lifting the funnel 2 from the top of the funnel 2, for example, connecting an electric hoist between the third lifting component 203 of the funnel 2 and the second lifting component 122 on the embedded steel plate 121, and tightening the electric hoist to move the funnel 2 in a direction close to the embedded steel plate 121.

[0092] In the above embodiment, before moving the funnel 2 upward, the funnel 2 can be first lifted until the bottom of the funnel 2 is off the ground, and then kept still for a specified time. After confirming that the force state of the funnel 2 and the electric hoist is stable, the funnel 2 can be further lifted to the specified elevation to prevent the large end of the funnel 2 from suddenly reopening due to changes in external loads, thereby causing a production safety accident.

[0093] In the above embodiment, if a hand winch is used to loosen the cable 4, the worker's safety belt can be hung on the pre-set hanging belt, and then the worker can operate the hand winch to prevent the funnel 2 from accidentally falling and causing the worker to fall with it.

[0094] S4, such as Fig.13As shown, the vertical seam 201 is assembled, for example, the steel plates of the funnel 2 on both sides of the vertical seam 201 are welded to each other; the funnel 2 is connected to the bottom plate 12, for example, the steel plates of the funnel 2 are welded to the embedded steel plate 121 through the plug welding holes 204.

[0095] In an optional embodiment, when the funnel 2 includes at least two segments 20, only the segment 20 close to the large end needs to be provided with a cable 4 to increase or decrease the diameter of the funnel 2, while the segment 20 close to the small end and not directly connected to the embedded steel plate 121 may not be provided with a cable 4; when hoisting the segments 20, each segment 20 may be hoisted into place separately and then connected, or two or more segments 20 may be connected to each other under the bottom plate 12 first, and then hoisted into place as a whole. The number of segments 20 hoisted each time depends on the actual hoisting capacity, for example, Figures 10 to 13 In the steps shown, the number of segments 20 hoisted each time is two.

[0096] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
