Description

Technical Field

[0001] This utility model relates to the field of coal chutes technology, specifically to an anti-clogging and wear-resistant coal chute. Background Technology

[0002] Coal chutes are core equipment used in industrial settings such as coal mines, thermal power plants, ports, and coal washing plants for conveying pulverized coal and coal lumps. They achieve efficient material transfer and diversion control through pipeline structures. They are generally installed at the connection and transition points between two pieces of equipment in a material conveying system, and are mainly used to guide lumpy or granular bulk materials to fall and transfer along their predetermined paths.

[0003] The anti-clogging curved coal drop pipe structure disclosed in Chinese utility model patent application CN223238701U uses vibration to clean different positions inside the pipe. However, this utility model requires an external vibration cleaning mechanism when cleaning the inner wall of the pipe. This not only consumes additional electrical energy, but the vibration transmitted to the components on the pipe will also affect their lifespan. Furthermore, when large coal blocks fall, they are prone to impacting the inner wall of the pipe, accelerating the wear of the inner wall.

[0004] Therefore, it is necessary to propose a clog-resistant and wear-resistant coal chuting pipe to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an anti-clogging and wear-resistant coal chuting pipe, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: it includes a conveyor belt and a steel frame, with a pipe fixedly connected to the bottom of the steel frame, the steel frame being bolted to the outer side wall of the end of the conveyor belt, and a support arm fixedly connected to the bottom of the steel frame away from the conveyor belt;

[0007] A horizontal connecting rod is provided at the bottom of the steel frame near the conveyor belt. An installation tube is fixedly connected to the end of the support arm away from the steel frame. A steel plate is detachably connected to the middle of the installation tube through a clamping ring. An impact plate is fixedly connected to the bottom of the steel plate, and a buffer belt is fixedly connected to the bottom of the impact plate.

[0008] Optionally, there are two steel frames, which are symmetrically installed on the outer side wall of the end of the conveyor belt. The steel frame as a whole is a rhombus shape composed of two right-angled triangles, so as to improve the stability and strength of the steel frame.

[0009] Optionally, the width of the buffer strip is equal to the width of the impact plate.

[0010] Optionally, bolt holes are evenly distributed at the bottom of the steel frame, and the top of the pipe is installed at the bottom of the steel frame by bolts.

[0011] Optionally, the clamping ring is composed of two semicircular rings hinged at both ends, and the mounting tube is welded to one of the semicircular rings. The ends of the two semicircular rings away from the hinge are detachably connected by bolts.

[0012] Optionally, the impact plate has crushing cones arranged in a rectangular array on the side closest to the conveyor belt.

[0013] Optionally, a steel pipe is welded to the bottom inner wall of the pipe, and hanging rings are welded at equal intervals in the middle of the steel pipe. Hanging holes are opened at equal intervals at the bottom of the impact plate. The top of the buffer strip is connected to the hanging holes through a carabiner, and the bottom of the buffer strip is connected to the hanging rings through a carabiner.

[0014] This utility model provides an anti-clogging and wear-resistant coal chuting pipe, which has the following beneficial effects:

[0015] 1. This anti-clogging and wear-resistant coal drop pipe, by setting an impact plate, can break up large pieces of coal when they fall from the conveyor belt onto the impact plate. At the same time, the impact plate swings, and the swing of the support arm can also cause the buffer belt to shake, causing the adhering coal debris to fall off, thereby achieving the purpose of automatic cleaning.

[0016] 2. This anti-clogging and wear-resistant coal drop pipe reduces the impact of coal blocks on the pipe by setting a buffer zone. After the coal blocks are broken by the impact plate, they fall directly onto the buffer zone, which causes the buffer zone to shake into the pipe, further automatically cleaning the surface of the buffer zone.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a clog-resistant and wear-resistant coal drop pipe, including a conveyor belt 1 and a steel frame 2. There are two steel frames 2, which are symmetrically installed on the outer side wall of the end of the conveyor belt 1. The steel frame 2 is a rhombus shape composed of two right triangles to improve the stability and strength of the steel frame 2. The bottom of the steel frame 2 is fixedly connected to a pipe 10. The steel frame 2 is installed on the outer side wall of the end of the conveyor belt 1 by bolts. The bottom of the steel frame 2 away from the conveyor belt 1 is fixedly connected to a support arm 6.

[0025] A horizontal connecting rod 11 is provided on the bottom side of the steel frame 2 near the conveyor belt 1. An installation pipe 7 is fixedly connected to the end of the support arm 6 away from the steel frame 2. A steel plate 9 is detachably connected to the middle of the installation pipe 7 through a clamping ring 8. An impact plate 12 is fixedly connected to the bottom of the steel plate 9. A buffer belt 14 is fixedly connected to the bottom of the impact plate 12.

[0026] Specifically, the end of the support arm 6 away from the steel frame 2 is fixedly connected to an installation pipe 7, and a steel plate 9 is detachably connected to the middle of the installation pipe 7 via a clamping ring 8. An impact plate 12 is fixedly connected to the bottom of the steel plate 9.

[0027] In this embodiment, as Figure 4 As shown, after the coal falls from the conveyor belt 1, it falls directly onto the impact plate 12 under the action of inertia, which can break the coal pieces by impact, reduce the impact of the coal pieces on the buffer belt 14, and also use the swing of the impact plate 12 after receiving the impact to drive the buffer belt 14 to swing, clean the coal dust on the buffer belt 14. Furthermore, after the broken coal pieces fall directly onto the buffer belt 14, the buffer belt 14 can be shaken laterally and inward, further automatically cleaning the buffer belt 14.

[0028] Specifically, the clamping ring 8 is a ring composed of two semi-circular rings hinged at both ends. The mounting tube 7 is welded to one of the semi-circular rings. The ends of the two semi-circular rings away from the hinge are detachably connected by bolts. The impact plate 12 has crushing cones 17 arranged in a rectangular array on one side near the conveyor belt 1.

[0029] like Figure 4 and Figure 5 As shown, this design facilitates the impact of coal onto the impact plate 12 and the crushing cone 17, further crushing the coal and preventing significant wear on the buffer zone 14.

[0030] Specifically, the width of the buffer strip 14 is equal to the width of the impact plate 12, and bolt holes 13 are evenly distributed at the bottom of the steel frame 2. The top of the pipe 10 is installed at the bottom of the steel frame 2 by bolts.

[0031] Specifically, a steel pipe 15 is welded to the bottom inner wall of the pipe 10, and hanging rings 16 are welded at equal intervals in the middle of the steel pipe 15. Hanging holes are opened at equal intervals at the bottom of the impact plate 12. The top of the buffer strip 14 is connected to the hanging holes through a carabiner, and the bottom of the buffer strip 14 is connected to the hanging rings 16 through a carabiner.

[0032] like Figure 4 As shown, when the buffer strip 14 needs to be replaced, the buffer strip 14 is removed using a carabiner. The top of the new buffer strip 14 is connected to the hanging holes at equal intervals on the bottom of the impact plate 12 using a carabiner. The bottom of the buffer strip 14 is then connected to the hanging ring 16 using a carabiner.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
