Description

Technical Field

[0001] The present invention relates to the technical field of pneumatic conveying, and in particular to an anti-blocking pneumatic conveying device. Background Art

[0002] A pneumatic conveying device is a device that uses gas as a conveying medium to transport solid particles or powders from one location to another. This device includes a pipeline system and a source of compressed air or other gas. By controlling the flow of gas, solid particles or powders can be transported along the pipeline to the target location.

[0003] The patent application with application number 202310844922.X discloses a pneumatic conveying equipment, including a discharge barrel, a first conveying pipe, a drying bin and a second conveying pipe, which belongs to the field of pneumatic conveying technology. The silicone rubber elastomer inside the curved pipe section, after colliding with the material, uses its own elasticity to eject the material, thereby reducing the kinetic energy loss of the material. At the same time, when the curved pipe section is blocked, the pipe is heated, the inner diameter of the pipe expands, and the flow space of the material is increased. The silicone rubber elastomer expands due to heat, squeezing the material, destroying the stable structure of the accumulated material, which is beneficial to the unblocking of the pipeline.

[0004] The above patent destroys the structure of the accumulated materials in the pipeline after the silicone rubber elastomer expands due to heat, thereby achieving the cleaning of the accumulated materials. However, in the process of gas conveying the materials, there will be irregular movement between the materials and between the materials and the inner wall of the conveying pipeline, and friction will generate heat, which will increase the gas temperature during transportation. In addition, the heating process of the silicone rubber elastomer will increase the gas temperature during transportation again. At this time, the high temperature may cause some materials to become sticky or agglomerated, increasing the risk of blockage during transportation. If the material is sensitive to temperature, the high temperature may cause the material to deteriorate, decompose or lose its activity.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Summary of the Invention

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, 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, not all embodiments.

When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 7 As shown, the present invention provides an anti-blocking pneumatic conveying device, comprising: a Roots blower 1; a conveying pipe 3 connected to the air outlet of the Roots blower 1; a storage bin 4 connected to the discharge end of the conveying pipe 3; a feeding mechanism 2 for feeding material into the conveying pipe 3; and an anti-blocking mechanism 5 for preventing the conveying pipe 3 from being blocked when conveying materials.

[0024] The feeding mechanism 2 includes: a feeder 22 communicated with the conveying pipe 3 ; and a hopper 21 communicated with the feeder 22 .

[0025] The material is stored in the hopper 21 and the material in the hopper 21 can be transported to the conveying pipe 3 through the feeder 22 .

[0026] By starting the Roots blower 1 , the airflow required for pneumatic conveying can be provided to the conveying pipe 3 , and the airflow drives the material to be conveyed along the path of the conveying pipe 3 to the storage bin 4 .

[0027] It should be added that a cyclone separator and a bag dust collector are also installed in the storage bin 4. The discharge end of the conveying pipe 3 is connected to the cyclone separator. The airflow containing materials and dust enters the inlet of the cyclone separator. The airflow rotates along the tangential direction in the cyclone separator, generating a strong centrifugal force. Under the action of the centrifugal force, the materials and dust with higher density are thrown to the wall of the device and fall along the wall to the collection bin. The separated gas is discharged from the central pipe of the cyclone separator and enters the bag dust collector. The cyclone separator mainly processes most of the dust and materials, reducing the load of the bag dust collector. The gas from the cyclone separator The air enters the air inlet of the bag filter, the gas passes through the filter bag, and the dust is trapped on the surface of the filter bag. The clean gas passes through the filter bag and enters the exhaust duct. As the dust accumulates on the surface of the filter bag, the dust collector will regularly remove the dust on the surface of the filter bag by vibration or backblowing air flow to maintain the filtering effect of the filter bag; the gas discharged from the cyclone separator still contains some fine dust particles; these gases enter the bag filter, and through the fine filtration of the filter bag, the fine dust is trapped on the surface of the filter bag, ensuring that the discharged gas meets environmental protection requirements. The material processed by the cyclone separator is transported to the storage bin 4 for storage.

[0028] The feeder 22 is preferably a rotary feeder; the rotary feeder is mainly composed of a main valve, a transmission shaft, blades, a reduction mechanism and a protective device. Among them, the main valve further includes components such as a housing, an end cover, an impeller, an air collecting pipe, bearings and an oil seal; its core structure is a rotor with several blades, which rotates in a cylindrical casing, and the material is transported through the spaces between the blades; when the motor drives the rotor to rotate, the material falls from the upper hopper and fills the spaces between the blades. As the rotor rotates, the material is evenly discharged to the bottom, thereby realizing continuous material transportation. In the pneumatic conveying system, the rotary feeder can not only complete the unloading function, but also effectively prevent the high-pressure gas from leaking through the feeder to the upper silo, ensuring the smooth fall of the material.

[0029] The anti-blocking mechanism 5 includes: a stirring component 51 for stirring the material in the conveying pipe 3; the stirring component 51 includes: a mounting frame 511; a fixed cylinder 512 fixedly mounted in the mounting frame 511; a piston 513 slidably mounted in the fixed cylinder 512; a cylinder 514 that drives the piston 513 to move; a rotating rod 516 rotatably mounted on the conveying pipe 3; a stirring blade 519 fixedly mounted on the rotating rod 516; a connecting pipe 515 slidably mounted on the rotating rod 516; a rolling element 517 rotatably mounted in the connecting pipe 515; a guide groove 518 provided on the rotating rod 516; the connecting pipe 515 is fixedly connected to the piston 513; the guide groove 518 is spiral, and the rolling element 517 is slidably mounted in the guide groove 518; the fixed end of the cylinder 514 is fixedly connected to the fixed cylinder 512, and the movable end of the cylinder 514 is fixedly connected to the piston 513.

[0030] While the material is being pneumatically conveyed, the starting cylinder 514 drives the piston 513 to move back and forth in the fixed cylinder 512 along the axial direction of the fixed cylinder 512, and the piston 513 drives the connecting pipe 515 to move back and forth in the axial direction of the fixed cylinder 512, thereby driving the rolling element 517 to slide in the guide groove 518. Since the guide groove 518 is spiral, it can drive the rotating rod 516 to rotate back and forth, and the rotating rod 516 drives the stirring blade 519 to rotate back and forth, thereby stirring up the material accumulated at the turning point of the conveying pipe 3, preventing the material from accumulating and agglomerating, which would cause the conveying pipe 3 to be blocked, and ensuring the material conveying effect.

[0031] It is added here that the rolling element 517 is preferably a bull's eye ball.

[0032] The anti-blocking mechanism 5 also includes: an injection assembly 52 for blowing away the material in the conveying pipe 3; the injection assembly 52 includes: a first capsule 521 fixedly installed in the fixed cylinder 512; an annular tube 522 connected to the first capsule 521; a nozzle 525 connected to the annular tube 522; a plurality of nozzles 525 are provided, and the plurality of nozzles 525 are arranged in an annular shape along the circumference of the annular tube 522, and the air outlet ends of the plurality of nozzles 525 are all plugged into and installed in the conveying pipe 3.

[0033] When the piston 513 moves axially back and forth in the fixed cylinder 512 , it can drive the first capsule 521 to be compressed and restored back and forth.

[0034] The first sac 521 is connected to the annular tube 522 through the air outlet pipe 524. The first sac 521 is also connected to the air inlet pipe 523. Both the air inlet pipe 523 and the air outlet pipe 524 are equipped with a one-way valve, so that air enters the first sac 521 through the air inlet pipe 523 and is discharged through the air outlet pipe 524.

[0035] Therefore, when the first sac 521 is compressed and restored back and forth, the outside air can be sucked into the first sac 521 through the air inlet pipe 523, and transported to the annular tube 522 through the air outlet pipe 524, and then sprayed out through the nozzle 525, so as to blow away the material accumulated at the turning point of the conveying pipe 3, prevent the material from accumulating and agglomerating, causing the conveying pipe 3 to be blocked, and further ensure the material conveying effect.

[0036] A brush 526 is fixedly mounted on one side of the stirring blade 519 close to the nozzle 525 .

[0037] When the stirring blade 519 rotates, the bristles 526 can be driven to rotate, thereby cleaning the nozzle 525 and preventing the nozzle 525 from being blocked by the material.

[0038] The anti-blocking mechanism 5 also includes: a cooling component 53 for cooling the gas in the delivery pipe 3; the cooling component 53 includes: a cooling box 531 fixedly installed in the mounting frame 511; a cooling pipe 534 fixedly sleeved on the delivery pipe 3; the cooling box 531 is respectively connected to the cooling pipe 534 and the fixed cylinder 512; the cooling pipe 534 is connected to the fixed cylinder 512.

[0039] The cooling box 531 is connected to the cooling pipe 534 through the liquid return pipe 535 , the cooling box 531 is connected to the fixed cylinder 512 through the liquid inlet pipe 532 , and the cooling pipe 534 is connected to the fixed cylinder 512 through the liquid outlet pipe 533 .

[0040] One-way valves are installed on both the liquid inlet pipe 532 and the liquid outlet pipe 533 . The one-way valves are used to allow the coolant in the cooling box 531 to enter the fixed cylinder 512 through the liquid inlet pipe 532 in one direction and be discharged through the liquid outlet pipe 533 .

[0041] The piston 513 divides the fixed cylinder 512 into two independent spaces. The space above the piston 513 stores liquid, and the space below the piston 513 stores gas.

[0042] When the piston 513 reciprocates along the axial direction of the fixed cylinder 512 in the fixed cylinder 512, the coolant in the coolant tank can be sucked into the fixed cylinder 512 through the liquid inlet pipe 532 and transported to the cooling pipe 534 through the liquid outlet pipe 533. The coolant entering the cooling pipe 534 can cool the delivery pipe 3, thereby cooling the air flow in the delivery pipe 3. The coolant after heat exchange flows into the cooling tank 531 through the return pipe 535, so that the coolant is circulated.

[0043] By cooling the airflow in the conveying pipe 3, it is avoided that high temperature may cause certain materials to become sticky or agglomerate, increasing the risk of blockage during transportation. If the material is sensitive to temperature, high temperature may cause the material to deteriorate, decompose or lose activity.

[0044] In addition, the first capsule 521 is located in the space where the fixed cylinder 512 stores liquid. Therefore, the cooling liquid can cool the air in the first capsule 521, so that the air sprayed toward the material by the nozzle 525 becomes cold air. The stirring blades 519 stir the material, so that the cold air can contact the material more fully, thereby further avoiding the problem that high temperature may cause certain materials to become sticky or agglomerate, increasing the risk of blockage during transportation, and avoiding the problem that high temperature may cause temperature-sensitive materials to deteriorate, decompose or lose activity.

[0045] It should be added here that the coolant in the cooling pipe 534 is introduced in a bottom-in and top-out manner, so that the cooling pipe 534 is filled with coolant, thereby fully cooling the airflow.

[0046] In the present invention, the material is stirred by the stirring blade 519, the material is sprayed by the nozzle 525, and the material is cooled by the coolant. On the one hand, the material is prevented from being blocked at the turning point of the conveying pipe 3, thereby ensuring the material conveying effect; on the other hand, the material can be cooled and cooled, thereby avoiding the high temperature that may cause some materials to become sticky or agglomerate, increasing the risk of blockage during the conveying process. If the material is sensitive to temperature, high temperature may cause the material to deteriorate, decompose or lose activity.

[0047] The cooling assembly 53 also includes: a stirring unit 536 for stirring the coolant in the cooling box 531; the stirring unit 536 includes: a limiting bar 5362 fixedly installed in the cooling box 531; a movable plate 5361 slidably installed on the limiting bar 5362; and a driving member 5366 for driving the movable plate 5361 to move.

[0048] The cooling box 531 is externally connected to a cold source, which is used to cool the coolant in the cooling box 531 to ensure the cooling effect of the coolant; the cold source is preferably a cooling unit.

[0049] The movable plate 5361 is driven to move by the driving member 5366 to stir the coolant. The driving member 5366 includes: a fixed tube 53661 installed on the cooling box 531; a movable tube 53662 slidably installed in the fixed tube 53661; a second capsule 53663 fixedly installed between the fixed tube 53661 and the movable tube 53662; the second capsule 53663 is connected to the fixed tube 512 through the air guide tube 53664.

[0050] That is, when the piston 513 moves back and forth in the fixed cylinder 512 along the axial direction of the fixed cylinder 512, the air in the air storage cavity of the fixed cylinder 512 can be squeezed out or sucked in back and forth. Since the second capsule 53663 is connected to the fixed cylinder 512 through the air guide tube 53664, the second capsule 53663 can expand and recover back and forth.

[0051] The reciprocating expansion and recovery of the second sac 53663 can drive the movable tube 53662 to move back and forth up and down. Under the limiting action of the limiting bar 5362, the movable plate 5361 can be driven to move back and forth up and down, thereby realizing vertical stirring of the coolant, causing the coolant to generate convection in the vertical direction, promoting the mixing of the coolant in the vertical direction, and making the cold source cool the coolant evenly.

[0052] The stirring unit 536 also includes: a mounting groove provided on the limiting bar 5362; a rack 5363 fixedly installed in the mounting groove; a linkage gear 5364 rotatably installed on the movable plate 5361; a stirring plate 5365 coaxially connected to the linkage gear 5364; the rack 5363 and the linkage gear 5364 are arranged to mesh with each other.

[0053] When the movable tube 53662 moves back and forth up and down, it can drive the stirring plate 5365 and the connecting gear 5364 to move. Since the connecting gear 5364 and the rack 5363 are meshed with each other, when the connecting gear 5364 moves with the movable plate 5361, the connecting gear 5364 rotates, thereby driving the stirring plate 5365 to rotate. The rotation of the stirring plate 5365 can further stir the coolant, expand the stirring range, make the coolant mixed evenly, and further make the cold source cool the coolant evenly.

[0054] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology.

It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.

[0055] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the appended claims of the present invention.
