Description

Technical Field

[0001] This utility model relates to a pneumatic ash conveying device with good flow guiding effect. Background Technology

[0002] Pneumatic conveying technology is a core method for transporting industrial powdery materials. With its advantages of good sealing, small footprint, and high degree of automation, it is widely used in industries such as power and metallurgy. It uses positive or negative pressure airflow to drive the material to suspend and flow within a pipeline, achieving the transfer from the point of generation to the storage terminal. However, in actual conveying processes, the frictional resistance and local resistance along the pipeline cause a continuous decrease in airflow energy, resulting in a reduction in the conveying velocity. When the kinetic energy of the ash material is insufficient to overcome its own weight and pipeline friction, ash deposition is easily triggered, leading to pipeline blockage and other problems that affect the stable operation of the system.

[0015] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0016] like Figures 1-7 As shown, the pneumatic ash conveying device with good flow guiding effect provided in this embodiment includes a device body 1. A mounting base 2 is provided on the horizontal ash conveying pipe of the device body 1. An air supply hole 3 is provided on the horizontal ash conveying pipe of the device body 1, penetrating the mounting base 2. A filter plate 4 is provided on the top of the mounting base 2. An air supply pipe 5 is provided on the filter plate 4. The air supply pipe 5 is fixedly connected to the mounting base 2. During the ash conveying process, air is supplied to the ash conveying pipe to promote the flow of ash material, enhance suspension, improve the smoothness of flow guiding, and reduce the risk of blockage. The filter plate 4 can filter the compressed air introduced by the air supply pipe 5 to prevent impurities from entering the ash conveying pipe. It can also block the ash material in the ash conveying pipe to prevent dust from flowing back into the air supply pipe 5, ensuring the smooth conveying of ash material.

[0017] The structure of the device body 1 can be achieved using existing technology, and the accompanying drawings in this application are for illustrative purposes only.

[0018] In this embodiment, as Figure 3 As shown, the air inlet 3 is set above the horizontal ash conveying pipe. The air inlet 3 is inclined along the conveying direction of the ash material, so that the air inlet is coordinated with the mainstream airflow in the ash conveying pipe in the same direction and will not generate opposing vortices.

[0019] In this embodiment, as Figure 2 As shown, the top of the mounting base 2 is provided with a groove 6, and the filter plate 4 is placed in the groove 6 to restrict the position of the filter plate 4 and prevent the filter plate 4 from shifting or misaligning during use.

[0020] In this embodiment, as Figure 3 As shown, the depth of the groove 6 is greater than the thickness of the filter plate 4. An insertion block 7 is provided at the bottom of the air supply pipe 5. The insertion block 7 is inserted into the groove 6 and pressed against the top surface of the filter plate 4, which increases the adhesion between the filter plate 4 and the mounting base 2 and reduces the risk of dust leakage from the edge of the filter plate 4 in the ash conveying pipe.

[0021] In this embodiment, as Figure 2 As shown, handles 8 are provided on both sides of the air inlet 3 on the filter plate 4, and handle grooves 9 are provided on the insertion block 7 to hold the handles 8. The handles 8 on the filter plate 4 can be directly lifted by the handles 8, which is labor-saving and convenient. The handle grooves 9 on the insertion block 7 provide space for the handles 8 to be accommodated, ensuring that the insertion block 7 will not be blocked by the handles 8 when pressing the filter plate 4.

[0022] In this embodiment, as Figure 2As shown, four spring grooves 10 are provided on the bottom surface of the groove 6 on the mounting base 2. The four spring grooves 10 are symmetrically arranged on both sides of the air inlet hole 3. A spring 11 is vertically installed in the spring groove 10. A pressure plate 12 is installed on the two springs 11 on the same side. A pressure plate groove 13 is provided on the bottom surface of the groove 6. During installation, the filter plate 4 is placed in the groove 6 and pressed on the pressure plate 12. The air inlet pipe 5 is inserted and fixed, so that the spring 11 is compressed. The elastic force of the spring 11 keeps the pressure plate 12 pressing the filter plate 4 upward, ensuring a tight connection.

[0023] In this embodiment, as Figure 4 As shown, a telescopic rod groove 14 is provided on the mounting base 2 between two spring grooves 10 on the same side. A telescopic rod 15 is provided in the telescopic rod groove 14, and the two ends of the telescopic rod 15 are respectively connected to the bottom surface of the telescopic rod groove 14 and the bottom surface of the pressure plate 12. The cooperation between the telescopic rod 15 and the telescopic rod groove 14 provides vertical guiding constraint for the pressure plate 12, ensuring that the pressure plate 12 always moves up and down along the axis of the telescopic rod 15. This ensures that the compression of the two springs 11 on the same side is consistent and the force is uniform, avoiding uneven force on the filter plate 4 caused by the tilt of the springs 11, and indirectly ensuring the stable passage of the guided airflow.

[0024] In this embodiment, as Figure 1 As shown, the top surface of the mounting base 2 is provided with a first flange 16, and the bottom surface of the air supply pipe 5 is provided with a second flange 17.

[0025] In summary, in this embodiment, the pneumatic ash conveying device provides an inclined air inlet 3 above the horizontal ash conveying pipe, ensuring that the incoming airflow is aligned with the ash conveying direction. This effectively promotes ash flow, enhances suspension, significantly improves flow smoothness, and reduces the risk of blockage. The structure of the filter plate 4 embedded in the mounting base 2 serves the dual purpose of filtering impurities and preventing dust backflow, ensuring smooth ash conveying. The combination of the groove 6, spring 11, and pressure plate 12 further strengthens the sealing and fixing of the filter plate 4. The overall structure is reasonable and reliable, effectively optimizing ash conveying efficiency and operational safety.

[0026] The above description is only a further 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 scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
