Description

TECHNICAL FIELD

[0001] The utility model relates to shrimp coal pipe transportation technical field, concretely relates to a shrimp coal pipe unblocking device. BACKGROUND

[0002] Shrimp coal pipe is a kind of pipeline specially used to solve the problem of coal blockage in coal hopper of power plant, and the design features of shrimp coal pipe include its unique curve shape, which can effectively prevent coal blocks from accumulating in the coal hopper. The design and application background of shrimp coal pipe is that the unreasonable structure of traditional coal bunker often causes coal blockage below the plug plate, which seriously affects the stable operation of the boiler. The power industry at home and abroad usually adopts manual knocking dredging, installation of air cannon, high-frequency vibrator and other methods, but the effect is not ideal, especially for wet coal and coal with high viscosity. SUMMARY

[0003] The utility model intends to provide a shrimp coal pipe unblocking device to solve the problem that the existing shrimp coal pipe unblocking can only be carried out once when blockage occurs.

[0004] To solve the above technical problems, the utility model provides the following technical scheme: a shrimp coal pipe unblocking device, comprising a pipeline and a shrimp coal pipe, the bottom of the shrimp coal pipe is connected with a dredging assembly, the dredging assembly comprises a lifting ring and a dredging block, the lifting ring and the pipeline are connected through a lifting assembly, the dredging block that moves up and down in the shrimp coal pipe along with the lifting ring is connected with the lifting ring.

[0005] The working principle of the utility model is as follows: when the shrimp coal pipe starts to transport mud coal, the lifting ring moves up and down under the driving of the lifting assembly, and simultaneously drives the dredging block to move up and down in the shrimp coal pipe, at this time, the mud coal in the shrimp coal pipe quickly passes through the shrimp coal pipe to the pipeline for transportation along with the movement of the dredging block.

[0006] The utility model has the advantages that: 1. By setting the dredging block that moves up and down along with the lifting ring in the shrimp coal pipe, the coal can be continuously dredged during transportation, and the interruption of transportation caused by blockage is avoided. 2. The design of the dredging block makes it difficult for coal to accumulate in the shrimp coal pipe to form blockage, thereby reducing the frequency and workload of manual dredging. 3. The unblocking device has a relatively simple structure, is easy to install and maintain, and reduces operating costs. 4. By continuous unblocking, smooth transportation of coal is ensured, and transportation efficiency is improved.

[0007] Further, the dredging block is a plurality of transmission rods, one end of the transmission rod is connected with the lifting ring, and the other end of the transmission rod penetrates the shrimp coal pipe and is located in the shrimp coal pipe. By setting the transmission rod, the coal can be stirred and transported by the transmission rod.

[0008] Further, the length of the transmission rod in the shrimp coal pipe is less than half of the radius of the shrimp coal pipe. Through the limitation of the length of the transmission rod, the normal flow of coal is not affected and the dredging is effectively carried out, and the internal space is fully utilized.

[0009] Further, the lifting assembly is a plurality of pneumatic lifting rods, the pneumatic lifting rods are connected to the pipeline, and the telescopic ends of the pneumatic lifting rods are connected with the lifting ring. Through the uninterrupted operation of the pneumatic lifting rods, the coal in the shrimp coal pipe can be continuously and uninterruptedly dredged.

[0010] Further, the connecting part of the shrimp coal pipe and the transmission rod is provided with a stable ring. Through the setting of the stable ring, the connection of the shrimp coal pipe and the transmission rod can be more stable.

[0011] Further, one end of the plurality of transmission rods in the shrimp coal pipe is connected with a connecting ring. Through the setting of the connecting ring, the end of the transmission rod in the shrimp coal pipe can be flush, and the coal can be better transported. BRIEF DESCRIPTION OF DRAWINGS

[0012] Figure 1 It is a structure diagram of the shrimp coal pipe dredging device of the utility model;

[0015] The following will be further described in detail through specific embodiments:

[0016] The reference signs in the drawings of the specification include: pipeline 1, shrimp coal pipe 2, dredging assembly 3, lifting ring 301, transmission rod 302, connecting ring 303.

[0017] The embodiment is basically as shown in the accompanying Figure 1 - the accompanying Figure 3As shown: A device for unblocking a coal pipe 2 includes a pipe 1, a coal pipe 2, and a dredging component 3. Two pneumatic lifting rods are fixedly connected to the top of the pipe 1. The dredging component 3 includes a lifting ring 301 and ten transmission rods 302. The bottom two ends of the lifting ring 301 are fixedly connected to the telescopic ends of the two pneumatic lifting rods respectively. One end of each of the ten transmission rods 302 is rotatably connected to the inner side of the lifting ring 301. The other ends of the ten transmission rods 302 penetrate the coal pipe 2 and are located inside the coal pipe 2. The length of the transmission rods 302 inside the coal pipe 2 is less than half the radius of the coal pipe 2. The connection between the coal pipe 2 and the transmission rods 302 is located on the same horizontal plane and is fixedly connected with a stabilizing ring. One end of each of the ten transmission rods 302 inside the coal pipe 2 is slidably connected to a connecting ring 303.

[0018] The specific implementation process is as follows: When the shrimp coal pipe 2 starts to transport pulverized coal, the lifting ring 301 moves up and down under the drive of the pneumatic lifting rod, and at the same time drives the ten transmission rods 302 to move up and down. At this time, the ten transmission rods 302 in the shrimp coal pipe 2 also move up and down. At this time, the pulverized coal in the shrimp coal pipe 2 is quickly transported through the shrimp coal pipe 2 to the pipeline 1 by the movement of the ten transmission rods 302.
