Description

Technical Field

[0001] This utility model belongs to the field of calcium carbide powder conveying technology, and in particular relates to a calcium carbide powder conveying device. Background Technology

[0002] Calcium carbide powder, also known as calcium carbide powder, is an important chemical raw material widely used in many industrial fields. In the production and processing of calcium carbide powder, transportation is a crucial link. Due to its hygroscopic, flammable and explosive properties, special attention must be paid to safety and sealing during transportation.

[0003] Existing calcium carbide powder conveying devices mostly use pneumatic conveying systems, which use airflow (positive or negative pressure) to transport materials from the starting point to the end point. However, due to problems such as poor material flowability, inertial collision, electrostatic adsorption, or moisture agglomeration, calcium carbide powder is prone to accumulate and blockage at the bends of the conveying pipeline, which not only affects production efficiency but may also lead to equipment damage or safety hazards. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a calcium carbide powder conveying device, and the technical solution adopted is as follows:

[0005] A calcium carbide powder conveying device includes a fixed frame disposed at a bend in a pipe. The fixed frame consists of two parts, which are fixedly connected by bolts. A mounting seat for installing a vibrator is provided in the lower part of the fixed frame.

[0006] An inner sleeve is provided inside the bend. The outer side of the inner sleeve is tightly fitted to the inner wall of the bend. Both ends of the inner sleeve extend to the straight section of the bend, and both ends of the inner sleeve are arc-shaped chamfers.

[0007] Furthermore, a support frame is provided at each end of the bend. The end of the support frame that contacts the bend is an arc-shaped plate. The arc-shaped plate is connected to an arc-shaped hoop by bolts. The arc-shaped hoop and the arc-shaped plate are combined to form a ring structure, which can fix the bend.

[0008] Furthermore, rubber pads are installed on the inner sides of both the arc plate and the arc hoop. The elasticity of the rubber pads can absorb the vibration generated by the vibrator, reduce the impact on the connection between the two ends of the bend and the straight pipe, and prevent the connection from loosening, which would affect the conveying of materials in the pipeline.

[0009] Furthermore, the fixing frame has the same curvature as the bend, and after installation, the fixing frame can fit tightly against the outer surface of the bend, ensuring that the vibration of the vibrator can be evenly transmitted to the bend.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This invention uses the vibration of a vibrator to disperse the material accumulated at the bend. The design of the fixing frame with the same curvature as the bend ensures that the vibration is evenly transmitted to the bend, effectively preventing the material from forming a blockage at the bend and ensuring the stable operation of the conveying system. Furthermore, an inner sleeve is set inside the bend. The Venturi effect formed by the inner sleeve inside the bend can accelerate the flow rate of the material at the bend, thereby reducing material deposition, improving conveying efficiency, and reducing maintenance costs.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0018] Example 1:

[0019] As attached Figure 1-2 As shown, a calcium carbide powder conveying device includes a fixed frame 2 set at the bend 1. The fixed frame 2 consists of two parts, which are fixedly connected by bolts. The lower part of the fixed frame 2 is provided with a mounting seat 3 for installing a vibrator 4. The vibration of the vibrator 4 can shake the material accumulated at the bend 1 to disperse it and prevent the material from adhering or accumulating at this point.

[0020] A support frame 5 is provided at each end of the bend 1. The installation angle of the support frame 5 is adjustable to meet the needs of bend 1 hoisting or other installation methods. At the end of the support frame 5 that contacts the bend 1, there is an arc plate. The arc plate can be connected to the arc hoist 51 by bolts. The arc hoist 51 and the arc plate are combined to form a ring structure, which can fix the bend 1. By setting rubber pads 52 on the inner side of the arc plate and the arc hoist 51, the vibration generated by the vibrator 4 can be absorbed by the elastic buffer of the rubber pads 52, reducing the impact on the connection between the two ends of the bend 1 and the straight pipe, and preventing the connection from loosening, which would affect the conveying of materials in the pipeline.

[0021] In this embodiment, by controlling the vibration frequency and duration of the vibrator 4, the accumulation of materials at the bend can be prevented, ensuring unobstructed flow and improving conveying efficiency. At the same time, the adjustable flexibility of the support frame 5 allows the device to adapt to different installation environments and meet the installation requirements of the bend, whether it is vertical or horizontal.

[0022] In this embodiment, the curvature of the fixing frame 2 is consistent with that of the bend 1, so that the fixing frame 2 can fit tightly with the bend and ensure that the vibration can be transmitted evenly to the bend 1.

[0023] Example 2:

[0024] As attached Figure 1-3 As shown, a calcium carbide powder conveying device includes a fixed frame 2 set at the bend 1. The fixed frame 2 consists of two parts, which are fixedly connected by bolts. The lower part of the fixed frame 2 is provided with a mounting seat 3 for installing a vibrator 4.

[0025] A support frame 5 is provided at each end of the bend 1. An arc plate is provided at the end of the support frame 5 that contacts the bend 1. The arc plate can be connected to the arc hoop 51 by bolts. The arc hoop 51 and the arc plate are combined to form a ring structure, which can fix the bend 1. A rubber pad 52 is provided on the inner side of the arc plate and the arc hoop 51.

[0026] An inner sleeve 6 is provided inside the bend 1. The outer side of the inner sleeve 6 is tightly fitted to the inner wall of the bend. Both ends of the inner sleeve 6 extend to the straight section of the bend 1, and both ends of the inner sleeve 6 are designed with arc chamfers, which can make the two ends of the inner sleeve 6 smoothly transition to the inner wall of the bend 1, forming a Venturi tube-like structure inside the bend 1. By utilizing the Venturi effect, the airflow velocity at the bend 1 can be increased, ensuring that the material can be effectively suspended and transported at the bend.

[0027] Compared to Example 1, this example further optimizes the smoothness of material conveying through the design of the inner sleeve 6, reduces the resistance at the bend, and significantly improves the material conveying efficiency through its use in conjunction with the vibrator 4.

[0028] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
