Description

Technical Field

[0001] This utility model relates to the field of negative pressure conveying technology, specifically to a durable, anti-jamming suction pipe. Background Technology

[0002] With the development of the carbon industry, the cleaning and covering of insulation materials during the carbon block roasting process has been upgraded from manual labor to automated operations using overhead conveyor cranes. The suction pipe is the core component for the automated conveying of powdery and granular materials.

[0003] However, the material characteristics in the carbon industry pose severe challenges to the suction pipe. On the one hand, the high hardness of powdery or granular materials will continuously generate strong friction and impact on the inner wall of the suction pipe during negative pressure conveying, aggravating wear. Factors such as drastic changes in material flow speed and direction, and high temperature, lead to more severe local wear, resulting in a significant reduction in the service life of the suction pipe. Frequent replacement not only increases maintenance costs but also affects production progress.

[0004] On the other hand, the suction pipe is prone to jamming. In carbon production, the particle size of materials varies relatively greatly. Some large particles will lose power and fall during the ascent due to their weight. They are very easy to accumulate and block at bends and diameter changes in the suction pipe. Jamming can cause the conveying to be interrupted. More seriously, long-term jamming may also cause equipment overload and damage supporting conveying equipment such as fans and vacuum pumps, posing a safety hazard. Utility Model Content

[0005] This invention provides a durable, anti-jamming suction tube to solve the technical problems in the prior art.

[0006] To solve the above problems, the durable anti-jamming suction pipe provided by this utility model adopts the following technical solution: it includes an inner tube for conveying materials, and the top outlet of the inner tube is provided with an anti-blocking structure to prevent material accumulation.

[0007] The outer tube of the suction tube is connected above the inner tube of the suction tube;

[0008] The square-to-round connecting pipe is used to provide more space for materials, reduce airflow speed, and thus reduce the scouring of materials on the wear-resistant elbow. The square-to-round connecting pipe is set above the outer pipe of the suction pipe and connected to the outer pipe of the suction pipe.

[0009] Ball joint, which is used to connect square to round pipe and wear-resistant elbow. The ball joint is installed on the square to round pipe and connected to the square to round pipe.

[0010] The wear-resistant elbow is located above the ball joint. The wear-resistant elbow is detachably connected to the ball joint for easy replacement.

[0011] By adopting the above technical solutions, the problems of clogging and severe wear in the suction pipe are solved. An anti-clogging structure is installed at the connection between the inner and outer suction pipes. If large particles lose momentum during ascent, they will fall along the anti-clogging structure, preventing material accumulation. Small particles are carried away by the high-speed airflow, achieving an anti-jamming function. The larger diameter of the square-to-round connecting pipe increases its internal space, reducing airflow velocity and thus reducing the erosion of the ball joint or wear-resistant elbow by the material, thereby extending its service life. The ball joint allows for partial oscillation; a slight deviation during the suction process does not affect operation or cause component deformation. Furthermore, the ball joint reduces sudden airflow swirl to a certain extent.

[0012] As a further improvement, the anti-clogging structure includes an inner wall panel, a reinforcing plate, and a sealing plate arranged sequentially from the inside to the outside. The inner wall panel, the reinforcing plate, and the sealing plate are staggered in height to form a stepped structure to prevent material accumulation.

[0013] By adopting the above technical solution, material accumulation is avoided. The sealing plate is detachable; if it is severely worn, it can be removed and replaced to restore the sealing effect.

[0014] As a further improvement, a gap is provided between the sealing plate and the outer tube of the suction pipe.

[0015] The gap between the sealing plate and the outer tube of the suction pipe should not be too large. A smaller gap improves the efficiency of the blower, allowing for frequency reduction operation of the blower on existing equipment to achieve energy savings and prevent large particles from getting stuck in the gap. Furthermore, this gap can also compensate for thermal expansion.

[0016] As a further improvement, movable liners are installed on the inner walls of both the wear-resistant elbows and ball joints.

[0017] As a further improvement, an observation port is provided on the side of the square-to-round connector to observe the internal wear.

[0018] As a further improvement, a suction nozzle is also connected to the lower part of the inner tube of the suction tube.

[0019] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0020] This invention features an anti-clogging structure. If large particles lose power during ascent, they will fall along the anti-clogging structure, preventing material accumulation. Small particles are carried away by the high-speed airflow, achieving an anti-jamming function. The square-to-round pipe has a larger diameter and a larger internal space, reducing the airflow speed and thus reducing the scouring of the ball joint or wear-resistant elbow by the material, thereby extending its service life.

[0021] This utility model has a compact structure, strong interchangeability, long service life, stable operation and high material suction efficiency, which can reduce energy consumption and reduce labor intensity and costs. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0028] In existing technologies, the carbon industry uses negative pressure conveying for materials. During negative pressure conveying, the inner wall of the suction pipe is continuously subjected to strong friction and impact, which exacerbates wear. Factors such as drastic changes in material flow speed and direction, and high temperatures, lead to more severe local wear, resulting in a significant reduction in the service life of the suction pipe. Frequent replacements not only increase maintenance costs but also affect production progress. On the other hand, the suction pipe is prone to jamming. In carbon production, the particle size difference of materials is relatively large. Some large particles, due to their weight, lose momentum and fall during the ascent, easily accumulating and clogging at bends and diameter changes in the suction pipe. Jamming can cause conveying interruptions. More seriously, prolonged jamming can also cause equipment overload, damaging supporting conveying equipment such as fans and vacuum pumps, posing safety hazards.

[0029] To address the aforementioned problems, this utility model incorporates an internal wall panel, a reinforcing plate, and a sealing plate in a stepped structure. Large particles will fall along this stepped structure after losing their upward momentum, thus preventing material accumulation and solving the problem of material blockage.

[0030] The diameter of the square-to-round pipe is larger, and its internal space is larger, which reduces the airflow speed and thus reduces the erosion of the ball joint or wear-resistant elbow by the material, thereby extending its service life.

[0031] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0032] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0033] Example 1 of the durable, anti-jamming, and suction-resistant feed tube provided by this utility model:

[0034] like Figure 1 and Figure 2 As shown, the durable, anti-jamming suction pipe includes, from bottom to top, an inner suction pipe 5, an outer suction pipe 4, a square-to-round connector 3, a ball joint 2, and a wear-resistant elbow 1. In addition, a suction nozzle (not shown in the figure) is connected below the inner suction pipe 5.

[0035] The top outlet of the inner tube 5 of the suction pipe is provided with an anti-clogging structure to prevent material accumulation. In this embodiment, the anti-clogging structure includes an inner wall panel, a reinforcing plate, and a sealing plate arranged sequentially from the inside to the outside. The inner wall panel, the reinforcing plate, and the sealing plate are staggered in height to form a stepped structure to prevent material accumulation. The inner wall panel is the pipe wall of the inner tube 5 of the suction pipe. The reinforcing plate and the sealing plate are both cylindrical structures. The inner wall panel, the reinforcing plate, and the sealing plate are detachably connected. When the sealing plate is worn, it is easy to replace it with a new one.

[0036] The outer suction pipe 4 is connected above the inner suction pipe 5; a gap is provided between the sealing plate and the outer suction pipe 4. The gap between the sealing plate and the outer suction pipe 4 should not be too large. A smaller gap improves the fan efficiency, allowing for frequency reduction operation of the fan on existing equipment to achieve energy savings, and preventing large particles from getting stuck in the gap. Furthermore, this gap can compensate for thermal expansion.

[0037] The square-to-round connecting pipe 3 is used to connect to the ball joint 2. The square-to-round connecting pipe 3 is set above the outer pipe 4 of the suction pipe and is connected to the outer pipe 4 of the suction pipe by bolts. The square-to-round connecting pipe 3 has a larger diameter and a larger internal space, which reduces the airflow speed and thus reduces the scouring of the material on the ball joint 2 or the wear-resistant elbow 1, thereby extending the service life.

[0038] The square-to-round connector 3 has an observation port 31 on its side to observe the internal wear.

[0039] The ball joint 2 is installed on and connected to the square-to-round pipe 3; the ball joint 2 can also achieve local swing, and a partial deviation during the material suction process will not affect the work or cause the component to deform.

[0040] The wear-resistant elbow 1 is positioned above the ball joint 2. The wear-resistant elbow 1 and the ball joint 2 are detachably connected so that the wear-resistant elbow 1 can be replaced.

[0041] In this embodiment, movable liners are installed on the inner walls of both the wear-resistant elbow 1 and the ball joint 2. When the movable liners wear out, new liners can be replaced, reducing maintenance costs.

[0042] While this specification has shown and described numerous embodiments of the present invention, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of the present invention. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover the modular compositions, equivalents, or alternatives within the scope of these claims.
