Description

Technical Field

[0001] The utility model relates to the field of material storage equipment, in particular to an arch breaking tool. Background Art

[0002] As a common material storage equipment, 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. The reciprocating movement of the slide promotes the internal material to move toward the discharge port at the bottom, and the slide breaks the arch structure formed by the internal material. For example, the utility model patent with patent application number 202321002533.4 discloses a sludge slide silo, which is provided with a bottom slide to promote the discharge of internal sludge. For some silos with higher heights, the upper part of the silo is often prone to arch structures, and the bottom slide often has a lag in breaking the arch structure of such arch structures. In some working conditions with highly compacted materials and a small inner width of the silo side, there may even be a condition of empty arches.

[0003] In the aforementioned patent, a sludge removal structure is set up in the silo, and the sludge removal structure mainly serves as a scraper and cleans the side wall after the sludge is discharged. During the sludge discharge process, when large pieces of sludge hang on the wall and the upper side of the bottom slide is arched, the frame structure of the removal frame and the sliding scraper in the prior art needs to move back and forth up and down, so it is light in weight and low in strength. It is easy to deform when moving up and down in the sludge, and it is difficult to move in the sludge to break the sludge, resulting in low internal arch breaking efficiency and affecting material discharge.

[0004] Therefore, it is urgent to improve the existing upper sludge arch breaking tool. Utility Model Content

[0007] Furthermore, the main beam is detachably connected to the upper blade plate by bolts, the main beam is connected to the lower blade plate by bolts, and the main beam is connected by bolts through the side broken arch plate.

[0008] Furthermore, the main beam is provided with an upper slot for inserting the upper blade plate and a lower slot for inserting the lower blade plate;

[0009] The upper blade plate is fixed to the main beam after the bolts pass through the side broken arch plate and the side wall of the upper slot, and the lower blade plate is fixed to the lower slot after the bolts pass through the side broken arch plate and the side wall of the lower slot.

[0010] Furthermore, the upper slot is communicated with the lower slot, and the upper blade plate is integrally connected with the lower blade plate.

[0011] Furthermore, the thickness of the side broken arch plate gradually decreases from the middle to both sides.

[0012] Furthermore, the side broken arch plate includes an upper plate and a lower plate connected to the lower side of the upper plate; the upper plate is arranged in an upward convex herringbone structure, and the lower plate is arranged in a downward convex V-shaped structure.

[0024] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0025] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0026] In the present utility model, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0027] 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.

[0028] In the present utility model, if Figure 1-3 As shown, an arch breaking tool is provided, comprising: a main beam 1, one side of the main beam 1 forming a mounting side; an upper blade 2, which is arranged at intervals on the top of the main beam 1 along the length direction of the main beam 1; a lower blade 3, which is arranged at intervals on the bottom of the main beam 1 along the length direction of the main beam 1; a side arch breaking plate 4, which is arranged on the mounting side of the main beam 1, and the side arch breaking plate 4 extends in a direction away from the main beam 1.

[0029] When the arch-breaking tool of the utility model is in use, the main beam 1 can be extended and arranged along the length direction of the inner wall of the silo, and the main beam 1 can be driven to move back and forth in the silo by the traction cylinder. When an arch structure appears in the upper half of the silo, the main beam 1 can move back and forth to drive the upper blade 2 and the lower blade 3 to break the wall hanging structure formed between the material and the side wall of the silo, so as to promote the destruction of the arch structure. At the same time, the side arch-breaking plates 4 can be set to promote the upper and lower separation of the material arch structure close to the side wall of the silo, so as to deeply destroy the arch structure at the wall hanging position of the side wall of the silo, and promote the downward movement of the arch structure after the destruction.

[0030] The arch-breaking tool of the utility model can break the arch comprehensively by setting plates in three directions, and the arch-breaking efficiency is high. After installation, the arch-breaking tool of the utility model can use the oil cylinder structure of the existing traction bottom slide to drive the reciprocating movement to break the arch, and the arch is cut and broken by the upper blade plate 2, the lower blade plate 3 and the side arch-breaking plate 4. The main beam 1 moves along its axial direction in the sludge particles, and the movement resistance of the main beam 1 is relatively low. The structural strength requirements of the main beam 1 are low. The main beam 1 can break the arch in a horizontal motion, and there is no need to lift the main beam 1. The traction power requirements for the main beam 1 are low, and it is easy to implement.

[0031] The arch breaking cutter of the utility model is particularly suitable for rectangular silos, and the arch breaking cutter is arranged in the long wall direction.

[0032] When the cutter of the utility model is in use, the two ends of the main beam 1 can be connected to the traction cylinder through a connecting rod to be pulled back and forth, and the connecting rod and the main beam can be welded or hinged. For the support of the main beam 1 in the silo, a supporting step for supporting the main beam 1 can be set in the silo, or a slide rail structure matched with the main beam 1 can be set in the silo.

[0033] For the structural setting of the utility model, in the illustrated embodiment, a further optimized setting is that the main beam 1 is detachably connected to the upper blade plate 2 by bolts, the main beam 1 is connected to the lower blade plate 3 by bolts, and the main beam 1 is connected by bolts through the side arch plate 4. As shown in the figure, the arch breaking tool is assembled by bolts, so that the upper blade plate 2, the lower blade plate 3, and the side arch plate 4 can be easily replaced.

[0034] As for the assembly structure of the arch-breaking tool, in a selected embodiment, more specifically, as shown in the figure, the main beam 1 is provided with an upper slot 5 for inserting the upper blade plate 2 and a lower slot 6 for inserting the lower blade plate 3; the bolts pass through the side arch-breaking plate 4 and the side wall of the upper slot 5 to fix the upper blade plate 2 to the main beam 1, and the bolts pass through the side arch-breaking plate 4 and the side wall of the lower slot 6 to fix the lower blade plate 3 to the lower slot 6. By providing the upper slot 5 and the lower slot 6, the upper blade plate 2 and the lower blade plate 3 can be stably positioned and fixed. By such a configuration, the bolts for fixing the side arch-breaking plate 4 and the upper blade plate 2 and the lower blade plate 3 can also be combined and utilized to reduce the number of bolts.

[0035] In the illustrated embodiment, for ease of installation, a further optimized setting is that the upper slot 5 is connected to the lower slot 6, the upper blade plate 2 is integrally connected to the lower blade plate 3, and the upper slot 5 is connected to the lower slot 6. Figure 3 As shown, the upper blade plate 2 and the lower blade plate 3 can be formed simultaneously by fixing one blade plate.

[0036] In the installation structure shown in the figure, Figure 3 As shown, the base of the side broken arch plate 4 is provided with a countersunk hole, and the main beam 1 is provided with a bolt hole. The bolts pass through the countersunk hole, the main beam 1, and the upper blade plate 2 (lower blade plate 3) and are fixed in the bolt hole.

[0037] In the illustrated embodiment, a further optimized setting is that the thickness of the side breaking arch plate 4 gradually decreases from the middle to the two sides. As shown in the figure, by such a setting, the strength can be increased by increasing the thickness of the middle position of the side breaking arch plate 4, and the bending deformation of the side breaking arch plate 4 can be reduced. Moreover, when the side breaking arch plate 4 cuts the arch structure, the middle thickness is used to increase the destruction and separation effect on the material, so as to promote the destruction of the arch structure.

[0038] In the illustrated embodiment, with respect to the structure of the side broken arch plate 4, to be more specific, as shown in the figure, the side broken arch plate 4 includes an upper plate 401 and a lower plate 402 connected to the lower side of the upper plate 401; the upper plate 401 is arranged to be an upwardly convex herringbone structure, and the lower plate 402 is arranged to be a downwardly convex V-shaped structure.

[0039] As shown in the figure, during processing, two V-shaped plates are buckled and welded to form the side broken arch plate 4, so that the side broken arch plate 4 can be easily processed and formed.

[0040] As selected, the length of the side broken arch plate 4 is less than or equal to 30cm and greater than or equal to 15cm. By controlling the upper limit of the length of the side broken arch plate 4, the material gravity borne by the side broken arch plate 4 is reduced to prevent the side broken arch plate 4 from bending, and by controlling the lower limit of the length of the side broken arch plate 4, it can be ensured that the side broken arch plate 4 has sufficient arch breaking capacity.

[0041] In the illustrated embodiment, a further optimized setting is that the top surface of the side-breaking arch plate 4 extends downward in a direction away from the main beam 1. As shown in the figure, this can promote the material on the side-breaking arch plate 4 to slide down from the top surface, reducing the material gravity on the side-breaking arch plate 4.

[0042] In the illustrated embodiment, in order to further reduce the bending moment of the side-breaking arch plate 4 due to the gravity of the material, a further optimized setting is that the width of the side-breaking arch plate 4 is gradually reduced in the direction away from the main beam 1. As shown in the figure, the side-breaking arch plate 4 can be roughly conical, which can ensure the cutting and breaking of the arch structure, and reduce the bearing area of ​​the far end of the side-breaking arch plate 4, thereby reducing the bending moment borne by the side-breaking arch plate 4.

[0043] In the illustrated embodiment, in order to further improve the structural strength of the side broken arch plate 4, a further optimized setting is that the side broken arch plate 4 also includes a supporting vertical plate 403 arranged between the upper plate 401 and the lower plate 402.

[0044] 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.

[0045] 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.
