Description

Technical Field

[0001] The invention relates to the technical field of pneumatic conveying, and in particular to an anti-blocking device for pipeline conveying of powdered chemical raw materials. Background Art

[0002] Powder pneumatic pipeline transportation is a powder raw material transportation method invented by combining the pneumatic difference principle, jet flow technology and liquefaction technology, and fully absorbing the theory of modern pneumatic transportation. It has the advantages of simple structure, reliable operation, long service life, pollution-free transportation and simple operation.

[0003] However, during pipeline transportation, the gas output pressure may be too low due to various reasons, causing the gas flow velocity to drop below the critical value, resulting in a large amount of powdered granular raw materials accumulating at the bottom of the pipeline. These accumulated powdered raw materials will slide or accumulate in the pipeline, and when accumulated to a certain extent, the pipeline will be blocked. In addition, due to the physical and chemical properties of the powdered raw materials themselves, static electricity will be generated during transportation due to friction between them, which will also cause the powdered raw materials to be adsorbed on the surface of the pipe wall, causing pipeline blockage.

[0004] It takes a long time to clear a pipeline after it is blocked, and in pneumatic conveying failures, pipeline blockage accounts for more than half. Faced with the problem that powdered chemical raw materials are easily blocked during pipeline transportation, it is necessary to prevent pipeline blockage in advance to reduce the probability of pipeline blockage. In addition, due to the high probability of powdered raw materials accumulating at the bottom of the pipeline, the bottom of the pipeline needs to be cleared in a targeted manner. However, the pipelines for transporting powdered chemical raw materials are generally long, making it inconvenient to clear the pipelines. Summary of the invention

[0005] In view of this, the present invention provides a powdered chemical raw material pipeline transportation anti-blocking device which can prevent and dredge the pipeline in advance, reduce the probability of pipeline blockage, and can specifically dredge the bottom of the pipeline.

[0006] The technical implementation scheme of the present invention is: a device for preventing blockage in pipeline transportation of powdered chemical raw materials, comprising a mounting ring, a mounting plate, a driving mechanism and a vibration mechanism, wherein the outer wall of the pipeline is fixedly connected to the mounting ring, the top of the mounting ring is fixedly connected to two mounting plates, and the two mounting plates are symmetrically arranged, the driving mechanism is arranged on the mounting plate, and the vibration mechanism is arranged on the driving mechanism.

[0007] Optionally, the driving mechanism includes a motor, a pinion and a large gear, a motor is fixedly connected between the upper parts of the two mounting plates, and the output shaft of the motor is rotatably connected to one of the mounting plates, a pinion is fixedly connected to the output shaft of the motor, a large gear is rotatably connected to the outer wall of the pipe, and the pinion is meshed with the large gear.

[0008] Optionally, the vibration mechanism includes a top block, a guide ring, a knocking rod and a return spring, eight top blocks are fixedly connected to the side of the large gear away from the motor, the guide ring is fixedly connected to the outer wall of the pipe, eight knocking rods are slidably connected to the guide ring, and each of the knocking rods is in contact with the outer wall of the pipe, and a return spring is fixedly connected between the knocking rod and the guide ring.

[0009] Optionally, the knocking rod is made of copper.

[0010] Optionally, it also includes balls, and a plurality of balls are rotatably connected in the guide ring, and each of the knocking rods is in contact with a plurality of the balls.

[0011] Optionally, a pressure mechanism is also included, which is arranged on the guide ring. The pressure mechanism includes a support ring, a pressure rod, a pressure spring and a pressure bevel ring. The guide ring is fixedly connected to the support ring, and a plurality of pressure rods are slidably connected to the support ring. A pressure spring is fixedly connected between each of the pressure rods and the knocking rod. The support ring is rotatably connected to the pressure bevel ring, and each of the pressure rods is in contact with the pressure bevel ring.

[0012] Optionally, the support ring is a circular ring structure.

[0013] Optionally, a knocking mechanism is also included, which is arranged on the mounting ring. The knocking mechanism includes an extrusion block, a mounting frame, a guide tube, a knocking hammer and a vertical spring. The large gear is fixedly connected to the extrusion block on the side close to the motor, the bottom of the mounting ring is fixedly connected to the mounting frame, the lower part of the mounting frame is fixedly connected to the guide tube, a knocking hammer is slidably connected in the guide tube, and the top of the knocking hammer is in contact with the pipeline, and a vertical spring is fixedly connected between the guide tube and the knocking hammer.

[0014] The beneficial effects of the present invention are:

[0015] 1. The staff starts the motor. The rotation of the motor's output shaft will drive the small gear, large gear and top block to rotate. The rotation of the top block will squeeze the knocking rod, causing the eight knocking rods to move away from each other. The top block will continue to rotate and will break away from the contact with the knocking rod. The reset spring will reset and drive the knocking rod to quickly move toward the direction close to the pipeline to reset. The knocking rod will hit the pipeline, thereby shaking off the powdered chemical raw materials attached to the inner wall of the pipeline. The top block will continue to rotate and contact the knocking rod again. In this reciprocating manner, the knocking rod will continuously hit the pipeline, thereby continuously and timely shaking off the powdered chemical raw materials attached to the inner wall of the pipeline, thereby reducing the chance of pipeline blockage and more effectively preventing pipeline blockage.

[0016] 2. The movement of the knocking rod will drive the ball to rotate, and rolling friction will occur between the knocking rod and the ball, so that the knocking rod can hit the pipeline at a higher speed, and then the powdered chemical raw materials attached to the inner wall of the pipeline can be shaken off more completely, further improving the pipeline cleaning effect, and further more effectively preventing pipeline blockage. When the pressurized spring is reset, the elastic potential energy will also be converted into the kinetic energy of the knocking rod, so that the knocking rod can hit the pipeline at a higher speed, and then the powdered chemical raw materials attached to the inner wall of the pipeline can be shaken off more completely, further improving the pipeline cleaning effect.

[0017] 3. The rotation of the large gear will drive the extrusion block to rotate, and the rotation of the extrusion block will contact the percussion hammer. The extrusion block will continue to rotate to squeeze the percussion hammer to move downward. The extrusion block will continue to rotate and will be out of contact with the percussion hammer. The vertical spring will reset, and the vertical spring reset will drive the percussion hammer to move upward and reset. The percussion hammer will move upward and reset and hit the bottom of the pipeline, so that the powdered chemical raw materials deposited at the bottom of the pipeline will bounce up, and then the powdered chemical raw materials deposited at the bottom of the pipeline will be cleaned in a targeted manner, further improving the cleaning effect of the pipeline.

Implementation

[0034] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments. Example

[0035] A device for preventing clogging of pipelines for conveying powdered chemical raw materials, such as Figure 1-Figure 7 As shown, it includes a mounting ring 2, a mounting plate 3, a driving mechanism and a vibration mechanism. The outer wall of the pipeline 1 is fixedly connected to the mounting ring 2. The top of the mounting ring 2 is connected to two mounting plates 3 by bolts, and the two mounting plates 3 are symmetrically arranged. The driving mechanism is arranged on the mounting plate 3, and the vibration mechanism is arranged on the driving mechanism. The vibration mechanism is used to knock the pipeline 1.

[0036] The driving mechanism includes a motor 41, a pinion 42 and a large gear 43. The motor 41 is connected between the upper parts of the two mounting plates 3 by bolts, and the output shaft of the motor 41 is rotatably connected to one of the mounting plates 3. The pinion 42 is connected to the output shaft of the motor 41 by a flat key, and the large gear 43 is rotatably connected to the outer wall of the pipeline 1, and the pinion 42 is meshed with the large gear 43.

[0037] The vibration mechanism includes a top block 51, a guide ring 52, a knocking rod 53 and a return spring 54. The large gear 43 is connected to eight top blocks 51 by bolts on the side away from the motor 41. The outer wall of the pipeline 1 is fixedly connected to the guide ring 52. Eight knocking rods 53 are slidably connected to the guide ring 52. The knocking rods 53 are made of red copper, and each of the knocking rods 53 is in contact with the outer wall of the pipeline 1. A return spring 54 is connected between the knocking rod 53 and the guide ring 52 by a hook.

[0038] In actual use, the staff starts the motor 41, and the rotation of the output shaft of the motor 41 drives the small gear 42 to rotate, and the rotation of the small gear 42 drives the large gear 43 and the top block 51 to rotate, and the top block 51 rotates to contact the knocking rod 53, and the top block 51 continues to rotate to squeeze the knocking rod 53, so that the eight knocking rods 53 move away from each other, and the reset spring 54 is compressed, and the top block 51 continues to rotate to break away from the contact with the knocking rod 53, and the reset spring 54 is reset, and the reset spring 54 resets, which drives the knocking rod 53 to quickly move toward the direction close to the pipeline 1 and reset. The knocking rod 53 will hit the pipeline 1, thereby shaking off the powdered chemical raw materials attached to the inner wall of the pipeline 1, and the top block 51 will continue to rotate and will contact the knocking rod 53 again. In this reciprocating manner, the knocking rod 53 will continuously hit the pipeline 1, thereby continuously and timely shaking off the powdered chemical raw materials attached to the inner wall of the pipeline 1, thereby reducing the probability of blockage of the pipeline 1 and more effectively preventing the blockage of the pipeline 1. After use, the staff turns off the motor 41, and the output shaft of the motor 41 no longer drives the small gear 42 to rotate, and the small gear 42 no longer drives the large gear 43 and the top block 51 to rotate. Example

[0039] On the basis of Example 1, Figure 6-Figure 8 As shown, it also includes balls 6. Several balls 6 are rotatably connected in the guide ring 52, and each of the knocking rods 53 is in contact with several of the balls 6. The balls 6 are used to reduce the friction between the guide ring 52 and the knocking rods 53.

[0040] When the eight knocking rods 53 move in the direction away from each other, the movement of the knocking rods 53 will drive the ball 6 to rotate, and the reset spring 54 will reset and drive the knocking rods 53 to move quickly in the direction close to the pipeline 1. When reset, the movement of the knocking rods 53 will drive the ball 6 to rotate, and the knocking rods 53 and the ball 6 will have rolling friction, so that the knocking rods 53 can hit the pipeline 1 at a greater speed, and then the powdered chemical raw materials attached to the inner wall of the pipeline 1 can be shaken off more completely, thereby further improving the cleaning effect of the pipeline 1, and further and more effectively preventing the blockage of the pipeline 1. Example

[0041] On the basis of Example 2, Figure 9-12As shown, a pressure mechanism is also included, which is arranged on the guide ring 52. The pressure mechanism includes a support ring 71, a pressure rod 72, a pressure spring 73 and a pressure bevel ring 74. The guide ring 52 is connected to the support ring 71 by bolts. The support ring 71 is a circular ring structure. A plurality of pressure rods 72 are slidably connected to the support ring 71. Each of the pressure rods 72 and the knocking rod 53 is connected to the pressure spring 73 by a hook. The support ring 71 is rotatably connected to the pressure bevel ring 74, and each of the pressure rods 72 is in contact with the pressure bevel ring 74.

[0042] Before use, the staff will rotate the pressure bevel ring 74 clockwise by a certain angle, and the pressure bevel ring 74 will squeeze the eight pressure rods 72 in the direction of approaching each other, and the pressure spring 73 will be compressed. When the pressure spring 73 is compressed to an appropriate degree, the staff will stop rotating the pressure bevel ring 74, and the pressure bevel ring 74 will no longer squeeze the eight pressure rods 72 in the direction of approaching each other. When the eight knocking rods 53 move in the direction of moving away from each other, the pressure spring 73 will continue to be compressed, and the reset spring 54 will reset and drive the knocking rod 53 to move quickly in the direction close to the pipeline 1. When reset, the pressure spring 73 will also reset, and the elastic potential energy of the pressure spring 73 will also be converted into the kinetic energy of the knocking rod 53, thereby further enabling the knocking rod 53 to hit the pipeline 1 at a greater speed, thereby further completely shaking off the powdered chemical raw materials attached to the inner wall of the pipeline 1, and further improving the cleaning effect of the pipeline 1. Example

[0043] On the basis of Example 1, Figure 13-Figure 15 As shown, a knocking mechanism is also included, which is arranged on the mounting ring 2. The knocking mechanism includes an extrusion block 81, a mounting frame 82, a guide tube 83, a knocking hammer 84 and a vertical spring 85. The large gear 43 is connected to the extrusion block 81 by rivets on the side close to the motor 41. The bottom of the mounting ring 2 is connected to the mounting frame 82 by bolts. The lower part of the mounting frame 82 is connected to the guide tube 83 by rivets. A knocking hammer 84 is slidably connected in the guide tube 83. The knocking hammer 84 is used to knock the bottom of the pipeline 1, and the top of the knocking hammer 84 is in contact with the pipeline 1. A vertical spring 85 is connected between the guide tube 83 and the knocking hammer 84 by a hook.

[0044] The rotation of the large gear 43 will drive the extrusion block 81 to rotate, and the rotation of the extrusion block 81 will contact the knocking hammer 84. The extrusion block 81 continues to rotate to squeeze the knocking hammer 84 to move downward, and the vertical spring 85 is compressed. The extrusion block 81 continues to rotate to break away from the contact with the knocking hammer 84, and the vertical spring 85 will reset. The reset of the vertical spring 85 will drive the knocking hammer 84 to move upward and reset. The upward movement and reset of the knocking hammer 84 will hit the bottom of the pipeline 1, thereby making the powdered chemical raw materials deposited at the bottom of the pipeline 1 bounce up, and then the powdered chemical raw materials deposited at the bottom of the pipeline 1 are cleaned in a targeted manner, further improving the cleaning effect of the pipeline 1.
