Description

Technical Field

[0001] This utility model belongs to the field of powder conveying technology, specifically, it relates to a petrochemical powder conveying anti-blocking device. Background Technology

[0002] In petrochemical production, the conveying of powder materials (such as catalyst powder, resin particles, and petrochemical by-product powders) is a crucial process connecting various production stages, and its conveying efficiency and stability directly affect the overall production progress. Currently, petrochemical powders are mainly conveyed pneumatically or mechanically through pipelines. Among these, the corners of the conveying pipelines (such as right-angle bends and oblique bends) are high-risk areas for blockage accidents due to abrupt changes in the flow direction of the powder.

[0003] The core reason for corner blockage is that petrochemical powders generally have a certain degree of viscosity, agglomeration and electrostatic force. When the powder flows through the corner of the pipeline, under the combined action of centrifugal force and friction, some powder is easy to break away from the main stream and adhere to the inner wall of the corner. As the conveying time increases, the adhered powder gradually accumulates and compacts, forming an "arch" or "bridging" phenomenon, which eventually leads to a reduction in the cross-section of the pipeline or even complete blockage.

[0004] Existing technologies include increasing the radius of curvature at corners to reduce flow resistance, periodically introducing high-pressure gas to purge, and manually tapping the pipes to disperse accumulated material. However, increasing the radius of curvature is limited by installation space and has limited applicability; high-pressure gas purging can easily cause powder to fly up again and consumes a lot of energy; manual tapping relies on experience and judgment, and its timeliness and anti-clogging effect are unstable, making it difficult to meet the needs of continuous and automated production.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies and provide a petrochemical powder conveying anti-blocking device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A petrochemical powder conveying anti-blocking device includes a conveying pipe and a support assembly for support. A bottom pipe is fixedly connected to the conveying pipe, and a pressure sensor is fixedly mounted on the bottom pipe. An mounting plate is fixedly mounted on the conveying pipe, and a vibration motor is fixedly mounted on the mounting plate. A first stabilizing plate is detachably connected to the conveying pipe, and a second stabilizing plate is detachably connected to the first stabilizing plate. Buffer pads are fixedly connected inside the first stabilizing plate and the second stabilizing plate, respectively. The buffer pads are in close contact with the conveying pipe, and the support assembly is disposed on the second stabilizing plate.

[0009] Preferably, the support assembly includes an outer tube, one end of which is fixedly connected to a rotating block, and an inner tube is threadedly connected to the inside of the outer tube to support the second stabilizing plate.

[0010] Preferably, a limiting block is fixedly connected to one end of the inner tube, and a first movable block is fixedly connected to the side of the limiting block away from the inner tube. The first movable block is hinged to a second stabilizing plate to adjust the support angle between the outer tube and the inner tube.

[0011] Preferably, the end of the rotating block away from the outer tube is rotatably connected to a second movable block, and the bottom of the second movable block is hinged to a bonding plate. The bonding plate has a positioning hole to facilitate the connection between the bottom of the rotating block and the ground or wall.

[0012] Preferably, bolts are threaded through the first and second stabilizing plates, and nuts are threaded onto the bolts to connect the first and second stabilizing plates together.

[0013] Preferably, the bottom of the bottom tube is threaded with a sealing cap, and a sealing gasket is tightly attached between the sealing cap and the bottom tube to seal the bottom of the bottom tube.

[0014] Preferably, a piston block is fixedly connected to the top of the sealing cap, and the piston block is in close contact with the delivery pipe to increase the sealing performance at the corner of the delivery pipe.

[0015] In summary, the technical effects and advantages of this utility model are as follows: In this petrochemical powder conveying anti-blocking device, petrochemical powder is transported from bottom to top through a conveying pipe. The pressure sensor monitors the pressure inside the conveying pipe. When the powder agglomerates and accumulates, the pressure value rises. The vibration motor causes the conveying pipe to vibrate, breaking up the accumulated material at the corners and preventing blockage at the corners inside the conveying pipe, thereby ensuring stable powder conveying.

[0016] The support height is adjusted by using the outer and inner tubes together. The first and second stabilizing plates are secured by using bolts and nuts together. The first and second movable blocks are used together to meet the requirements for inclined or horizontal installation of the conveying pipe, so that the bonding plate is attached to the ground or wall, ensuring that the conveying pipe does not shift when vibrating and improving the stability of the support.

[0022] This utility model provides a petrochemical powder conveying anti-clogging device. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0023] Reference Figure 1-2 A petrochemical powder conveying anti-blocking device includes a conveying pipe 1 and two sets of support components 8. The two sets of support components 8 are distributed on the conveying pipe 1. A bottom pipe 2 is fixedly connected to the conveying pipe 1. The powder flows and is conveyed from bottom to top. A pressure sensor 3 is fixedly installed on the bottom pipe 2 to monitor the internal pressure on the left side of the conveying pipe 1. A mounting plate 4 is fixedly installed on the conveying pipe 1, and a vibration motor 5 is fixedly installed on the mounting plate 4. A first stabilizing plate 6 is detachably connected to the conveying pipe 1. There is a second stabilizing plate 7. The number of the first stabilizing plate 6, the second stabilizing plate 7 and the support component 8 are equal and correspond one-to-one. The first stabilizing plate 6 and the second stabilizing plate 7 are respectively fixedly connected to the inside of the buffer pad 9. The buffer pad 9 is mainly made of rubber material and has a certain elasticity. The buffer pad 9 is in close contact with the conveying pipe 1. The support component 8 is set on the second stabilizing plate 7. After the corner inside the conveying pipe 1 is blocked, the vibration motor 5 on the mounting plate 4 runs, causing the conveying pipe 1 to vibrate and shake off the accumulated material at the corner, so as to avoid blockage at the corner inside the conveying pipe 1.

[0024] Reference Figure 1-3 The support assembly 8 includes an outer tube 81, with a rotating block 82 fixedly connected to one end of the outer tube 81. The rotating block 82 is located at the bottom center of the outer tube 81. An inner tube 83 is threadedly connected to the inside of the outer tube 81. The outer tube 81, the rotating block 82, and the inner tube 83 are coaxial. The outer side wall of the inner tube 83 is adapted to the inner side wall of the outer tube 81. The rotating block 82 drives the outer tube 81 to rotate, thereby adjusting the support length.

[0025] Reference Figure 1-3One end of the inner tube 83 is fixedly connected to a limiting block 84. A first movable block 85 is fixedly connected to the side of the limiting block 84 away from the inner tube 83. The first movable block 85 is located at the center of one side of the limiting block 84. The first movable block 85 is hinged to the second stabilizing plate 7. The first movable block 85 facilitates the adjustment of the support angle of the limiting block 84.

[0026] Reference Figure 1-3 The rotating block 82 is rotatably connected to a second movable block 86 at the end away from the outer tube 81. The bottom of the second movable block 86 is hinged to a bonding plate 87. The second movable block 86 facilitates the adjustment of the angle of the bonding plate 87. The bonding plate 87 is provided with a positioning hole 88. The bonding plate 87 is adjusted to fit against the ground or wall, thereby providing stable support for the conveying pipe 1.

[0027] Reference Figure 1-2 Bolts 10 are threaded through the first stabilizing plate 6 and the second stabilizing plate 7. Nuts 11 are threaded onto the bolts 10. The bolts 10 and nuts 11 are compatible. The first stabilizing plate 6 and the second stabilizing plate 7 are detachably mounted on the conveying pipe 1 by means of bolts 10 and nuts 11.

[0028] Reference Figure 1 and Figure 4 The bottom of the bottom pipe 2 is threaded with a sealing cap 12. The sealing cap 12 is convenient for sealing the bottom of the bottom pipe 2 and for cleaning the corner of the conveying pipe 1. A sealing gasket 14 is tightly attached between the sealing cap 12 and the bottom pipe 2. The sealing gasket 14 is mainly made of rubber and is used to seal the bottom of the bottom pipe 2.

[0029] Reference Figure 4 A piston block 13 is fixedly connected to the top of the sealing cover 12. The piston block 13 is in close contact with the conveying pipe 1. The piston block 13 makes the powder flow stably inside the conveying pipe 1, while preventing powder leakage.

[0030] Working principle: Pressure sensor 3 continuously monitors the powder pressure at the corner of conveying pipe 1 and bottom pipe 2. When powder accumulates at the corner due to agglomeration, flow rate changes, etc., the pressure value rises and triggers a threshold alarm, starting vibration motor 5. Vibration is transmitted to conveying pipe 1 through mounting plate 4, causing high-frequency vibration in the corner area to disperse the accumulated powder and prevent blockage. The outer pipe 81 and inner pipe 83 are threaded together to adjust the support height to adapt to different installation spaces. The first movable block 85 is hinged to the second stabilizing plate 7, allowing flexible adjustment of the support angle to meet the needs of inclined or horizontal pipe installation. Rotating block 82 carries... The second movable block 86 rotates, causing the bonding plate 87 to adhere to the ground or wall surface and be fixed by the fixing bolt through the positioning hole 88, ensuring that the pipeline does not shift during vibration and improving support stability. The first stabilizing plate 6 and the second stabilizing plate 7 are detachably connected by bolts 10 and nuts 11. The inner buffer pad 9 not only buffers the vibration impact but also reinforces the corner structure, preventing the pipeline from being damaged by high-frequency vibration. The sealing cover 12 is threaded to seal the bottom of the bottom pipe 2, and its top piston block 13 fits tightly against the inner wall of the conveying pipe 1, blocking the path of powder leakage or accumulation from the corner gaps, making it easy to clean the internal corners of the conveying pipe 1.
