Description

Technical Field

[0001] This utility model relates to the field of coal transportation or storage technology, and in particular to a coal hopper opening door and a coal hopper. Background Technology

[0002] In coal conveying systems, coal hoppers are key devices used for temporary storage, buffering, and regulation of coal flow. They are typically installed at key points in the conveying process, such as above boiler feeders or belt conveyor transfer points. Their core function is to ensure a continuous and stable supply of coal to downstream equipment, while also addressing issues such as blockages, impacts, and dust generation during the conveying process.

[0003] To facilitate observation and maintenance of the coal hopper's interior, inspection or observation holes are typically provided on the side walls. However, traditionally, the doors used for these holes are installed by welding reinforcing plates to the outer edges of the plates. This method, however, lacks support in the middle of the plates and the outer edges are not directly connected to the coal hopper's side walls, making the plates prone to deformation under the pressure of burning coal, thus affecting the normal operation of the coal hopper.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The purpose of this utility model is to provide a coal hopper opening door and a coal hopper to solve the problems existing in the prior art. By supporting the base plate with reinforcing plates and mounting plates, the stability of the coal hopper opening door during use is improved.

[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Please refer to Figure 1-6 The coal hopper opening door disclosed in this embodiment of the present invention includes: a base plate 1, a mounting plate 2, and a reinforcing plate 3; wherein the thickness of the base plate 1 is the same as the thickness of the coal hopper sidewall, the size of the base plate 1 matches the opening of the coal hopper sidewall, that is, the size of the base plate 1 matches the opening of the coal hopper sidewall, and the curvature of the base plate 1 matches the curvature of the opening position of the coal hopper sidewall. Therefore, the base plate 1 can completely seal the opening of the coal hopper sidewall. The side of the mounting plate 2 near the coal hopper sidewall matches the curvature of the opening position of the coal hopper sidewall. The base plate 1 is installed on the side of the mounting plate 2 near the coal hopper sidewall. Along the extension direction of the connecting surface between the mounting plate 2 and the base plate 1, the entire outer edge of the mounting plate 2 extends to the outside of the base plate 1. The portion of the mounting plate 2 extending to the outside of the base plate 1 is used to abut against the coal hopper sidewall. The reinforcing plate 3 is installed on the outer surface of the mounting plate 2 away from the base plate 1. Along the extension direction of the outer surface, the first end of the reinforcing plate 3 extends beyond the mounting plate 2. The mounting plate 2 is detachably connected to the side wall of the coal hopper, and the side of the mounting plate 2 away from the first end of the reinforcing plate 3 is rotatably connected to the side wall of the coal hopper. The working principle of the coal hopper opening door is as follows: the first end of the reinforcing plate 3 is detachably connected to the side wall of the coal hopper, and the mounting plate 2 is rotatably connected to the side wall of the coal hopper. When the first end of the reinforcing plate 3 is connected to the side wall of the coal hopper, the base plate 1 can be moved out of the opening by rotation. When it is necessary to seal the opening, the base plate 1 is moved into the opening by rotation, and the first end of the reinforcing plate 3 is connected to the side wall of the coal hopper, thereby realizing the opening and closing of the opening. The reinforcing plate 3 can provide support for the mounting plate 2, and the mounting plate 2 can provide support for the base plate 1 as a whole, avoiding the problem of deformation of some parts of the base plate 1 due to lack of support, and improving the stability of the coal hopper opening door during use. Furthermore, setting the base plate 1 to match the opening can effectively prevent coal slag from accumulating at the opening position.

[0033] In this embodiment, the shape, thickness, and curvature of the substrate 1 are all matched with the sidewall of the opening position of the coal hopper.

[0034] In this embodiment, the coal hopper sidewall is cut at the location where holes need to be made, and the cut-off plate is used as substrate 1.

[0035] In this embodiment, a flexible sealing gasket is provided between the outer edge of the substrate 1 and the inner edge of the opening. The flexible sealing gasket can fill the mating gap reserved in order to allow the substrate 1 to enter the opening smoothly. When the substrate 1 enters the opening, the flexible sealing gasket can be compressed, thereby improving the sealing performance of the coal hopper opening door.

[0036] In this embodiment, the coal hopper opening door also includes a hinge. The fixed end of the hinge is used to connect with the side wall of the coal hopper, and the movable end of the hinge is connected with the outer surface of the mounting plate 2. At this time, the second end of the reinforcing plate 3 is located on the mounting plate 2. One side of the mounting plate 2 is connected to the coal hopper through the hinge, and the other side is connected to the coal hopper through the reinforcing plate 3, which ensures the stability of the connection between the mounting plate 2 and the coal hopper, thereby providing stable support for the base plate 1. This configuration can be used as the opening and closing door of an observation window with a small opening size.

[0037] In this embodiment, the observation window is circular with a diameter of 200mm.

[0038] In this embodiment, the hinge includes a first rotating shaft 4, a first mounting ear 5, and a connecting plate 6. Both the first mounting ear 5 and the connecting plate 6 are mounted on the first rotating shaft 4. At least one of the first mounting ear 5 and the connecting plate 6 is rotatably connected to the first rotating shaft 4. The first mounting ear 5 serves as a fixed end for connecting to the side wall of the coal hopper, and the connecting plate 6 serves as a movable end for connecting to the outer surface of the mounting plate 2. At least two first mounting ears 5 and two connecting plates 6 are provided, which effectively ensures the connection stability between the mounting plate 2 and the side wall of the coal hopper.

[0039] In this embodiment, two connecting plates 6 are spaced apart, and each connecting plate 6 has a mounting hole for mounting a rotating shaft. The rotating shaft is installed in the mounting hole, and both ends of the rotating shaft are provided with a stop block to prevent the rotating shaft from coming out of the mounting hole. The stop block is bolted to the rotating shaft. Two first mounting ears 5 are spaced apart between the two connecting plates 6, and the two first mounting ears 5 are rotatably connected to the first rotating shaft 4.

[0040] In this embodiment, two reinforcing plates 3 are provided. The second ends of the two reinforcing plates 3 extend beyond the mounting plate 2 along the extension direction of the outer surface. A second rotating shaft 7 is installed at the second end of the reinforcing plate 3. A second mounting ear 8 is sleeved on the second rotating shaft 7. The second mounting ear 8 is used to connect with the side wall of the coal hopper. With this arrangement, both ends of the reinforcing plates 3 are directly connected to the side wall of the coal hopper, which can provide more stable support for the mounting plate 2 and further improve the strength of the coal hopper opening door. This arrangement can be used as the opening and closing door of the manhole with a large opening size, so that workers can enter the coal hopper through the manhole to carry out operations.

[0041] Preferably, the manhole is a square hole with a side length of 400mm.

[0042] In this embodiment, multiple second mounting ears 8 are provided to improve the connection strength between the reinforcing plate 3 and the side wall of the coal hopper. Preferably, two second mounting ears 8 are provided.

[0043] In this embodiment, the reinforcing plate 3 can be configured with three, four or even more reinforcing plates according to actual needs.

[0044] In this embodiment, the first end of the reinforcing plate 3 is provided with a snap-fit ​​groove 9, and an mounting base 10 is installed on the outer wall of the coal hopper. A connecting rod 11 is provided on the mounting base 10, and the connecting rod 11 is correspondingly provided with the snap-fit ​​groove 9. The connecting rod 11 is used to extend into the snap-fit ​​groove 9. A clamping element is provided at the end of the connecting rod 11 away from the mounting base 10. The clamping element is used to clamp the first end of the reinforcing plate 3 onto the mounting base 10. In use, by rotating the coal hopper opening door, the connecting rod 11 can be inserted into the snap-fit ​​groove 9. The size of the clamping element is larger than the size of the snap-fit ​​groove 9. Installing the clamping element at the end of the connecting rod 11 can prevent the connecting rod 11 from detaching from the snap-fit ​​groove 9. When it is necessary to open the coal hopper opening door, the clamping element can be removed from the end of the connecting rod 11, and the snap-fit ​​groove 9 and the connecting rod 11 can be separated. Through the cooperation of the snap-fit ​​element and the snap-fit ​​groove 9, the first end of the reinforcing plate 3 and the outer wall of the coal hopper can be quickly clamped and separated.

[0045] In this embodiment, the locking component is a buckle, the size of which is larger than the size of the locking groove 9. A groove is provided on the outer wall of the connecting rod 11 along the axial direction of the connecting rod 11. When in use, the buckle is locked into the groove to lock the coal hopper opening door.

[0046] In this embodiment, the clamping component is a clamping nut 12. The clamping nut 12 is threadedly connected to the end of the connecting rod 11 away from the mounting base 10. The size of the clamping nut 12 is larger than the size of the clamping groove 9. When in use, the clamping nut 12 is tightened so that it abuts against the reinforcing plate 3, thereby locking the coal hopper opening door. The clamping nut 12 has the advantages of stable connection and easy operation, making the coal hopper opening door easier to open and close.

[0047] In this embodiment, an auxiliary rod 13 is provided on the outer wall of the clamping nut 12. The auxiliary rod 13 extends away from the axis of the clamping nut 12. The operator can directly disassemble the clamping nut 12 through the auxiliary rod 13 without the need for tools, which improves the convenience of opening and closing the coal hopper opening door.

[0048] In this embodiment, the connecting rod 11 is rotatably mounted on the mounting base 10. The rotation axis of the connecting rod 11 is perpendicular to the opening direction of the snap-fit ​​groove 9, and the rotation trajectory of the connecting rod 11 coincides with the snap-fit ​​groove 9. By setting the connecting rod 11 to be rotatable, when it is necessary to open the coal hopper opening door, simply loosen the clamping nut 12, and the coal hopper opening door can be opened freely by rotating the connecting rod 11 without having to remove the clamping nut 12 from the connecting rod 11, which further improves the convenience of using the device.

[0049] In this embodiment, the reinforcing plate 3 is parallel to the mounting plate 2, that is, the width direction of the reinforcing plate 3 is set along the extension direction of the mounting plate 2, and the reinforcing plate 3 is attached to the mounting plate 2. With this arrangement, the reinforcing plate 3 can not only provide support for the mounting plate 2, but also increase the overall strength of the coal hopper opening door.

[0050] In this embodiment, the reinforcing plate 3 is parallel to the mounting plate 2, and the snap-fit ​​groove 9 is opened at the end of the first end of the reinforcing plate 3, with the opening direction of the snap-fit ​​groove 9 facing away from the second end of the reinforcing plate 3.

[0051] In this embodiment, the reinforcing plate 3 is perpendicular to the mounting plate 2, that is, the thickness direction of the reinforcing plate 3 is set along the extension direction of the mounting plate 2. This arrangement allows the reinforcing plate 3 to provide stronger support for the mounting plate 2.

[0052] It is understandable that the length of the reinforcing plate 3 is greater than its width and its thickness.

[0053] In this embodiment, the reinforcing plate 3 is perpendicular to the mounting plate 2. An auxiliary plate is provided on the reinforcing plate 3 and is connected to the reinforcing plate 3. A snap-fit ​​groove 9 is opened on the auxiliary plate, and the opening of the snap-fit ​​groove 9 faces the side away from the second end of the reinforcing plate 3.

[0054] In this embodiment, the first end of the reinforcing plate 3 is tilted away from the axis of the coal hopper, which provides sufficient space for the installation of the mounting base 10 and the connecting rod 11. This prevents the problem that the first end of the reinforcing plate 3 can no longer move towards the side wall of the coal hopper before the base plate 1 has fully entered the opening, thus ensuring the normal use of the coal hopper opening door.

[0055] This utility model embodiment also discloses a coal hopper, which uses the above-mentioned coal hopper opening door, and the coal hopper opening door is installed at the opening position on the side wall of the coal hopper.

[0056] This embodiment discloses a coal conveying system that uses the aforementioned coal hopper.

[0057] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
