The terms "vertical", "horizontal", "left", "right" and the like used herein are only for illustrative purposes.

[0034] As shown in Figures 1 to 7 The present application is a kind of anti-blocking pneumatic conveying equipment, comprising: Roots blower 1;With the air outlet hole of Roots blower 1 Communication conveying pipe 3;With the discharge end of conveying pipe 3 Communication storage bin 4;Feeding mechanism 2 to the feeding of conveying pipe 3;Anti-blocking mechanism 5 prevents the blockage of conveying pipe 3 when conveying material.

[0035] The feeding mechanism 2 comprises a feeder 22 communicating with the conveying pipe 3, and a hopper 21 communicating with the feeder 22.

[0036] The material is stored in the hopper 21, and the material in the hopper 21 can be conveyed into the conveying pipe 3 through the feeder 22.

[0037] By starting the Roots blower 1, the airflow required for pneumatic conveying can be provided into the conveying pipe 3, and the airflow carries the material along the path of the conveying pipe 3 to the storage bin 4.

[0038] It is supplemented here that a cyclone separator and a bag-type dust collector are also installed in the storage bin 4, the discharge end of the conveying pipe 3 communicates with the cyclone separator, the airflow containing the material and dust enters the inlet of the cyclone separator, the airflow rotates in the tangential direction in the cyclone separator, and a strong centrifugal force is generated, under the action of the centrifugal force, the material and dust with higher density are thrown to the wall 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-type dust collector, the cyclone separator mainly processes most of the dust and material, and reduces the load of the bag-type dust collector; the gas from the cyclone separator enters the gas inlet of the bag-type dust collector, the gas passes through the filter bag, the dust is intercepted on the surface of the filter bag, and the clean gas penetrates the filter bag and enters the exhaust pipe; as the dust on the surface of the filter bag accumulates, the dust collector will periodically remove the dust on the surface of the filter bag through vibration or backflow of the airflow, so as to maintain the filtering effect of the filter bag; the gas discharged from the cyclone separator still contains part of the fine dust particles; these gases enter the bag-type dust collector and are finely filtered by the filter bag, and the fine dust is intercepted on the surface of the filter bag, so as to ensure that the discharged gas meets the environmental protection requirements, and the material processed by the cyclone separator is conveyed into the storage bin 4 for storage.

[0039] The feeder 22 is preferably a rotary feeder; the rotary feeder mainly comprises a main valve, a transmission shaft, a blade, a speed reduction mechanism, a protection device and the like. The main valve comprises a shell, an end cover, an impeller, a gas collecting pipe, a bearing and an oil seal and the like; the core structure is a rotor with a plurality of blades rotating in a cylindrical shell, and the material is conveyed through the space between the blades; when the motor drives the rotor to rotate, the material falls from the upper hopper and fills in the space between the blades. With the rotation of the rotor, the material is uniformly discharged to the lower part, so as to realize the continuous conveying of the material. In the pneumatic conveying system, the rotary feeder not only can complete the unloading function, but also can effectively prevent the high-pressure gas from leaking to the upper hopper through the feeder, so as to ensure the smooth falling of the material.

[0040] The anti-blocking mechanism 5 comprises a stirring assembly 51 for stirring the material in the conveying pipe 3; the stirring assembly 51 comprises a mounting frame 511, a fixed cylinder 512 fixedly installed in the mounting frame 511, a piston 513 slidingly installed in the fixed cylinder 512, a pneumatic cylinder 514 for driving the piston 513 to move, a rotating rod 516 rotatably installed on the conveying pipe 3, stirring blades 519 fixedly installed on the rotating rod 516, a connecting pipe 515 slidingly installed on the rotating rod 516, a rolling element 517 rotatably installed in the connecting pipe 515, a guide groove 518 formed in the rotating rod 516, and the connecting pipe 515 is fixedly connected with the piston 513; the guide groove 518 is helical, and the rolling element 517 is slidingly installed in the guide groove 518; the fixed end of the pneumatic cylinder 514 is fixedly connected with the fixed cylinder 512, and the movable end of the pneumatic cylinder 514 is fixedly connected with the piston 513.

[0041] When the material is pneumatically conveyed, the pneumatic cylinder 514 is started to drive the piston 513 to reciprocally move in the fixed cylinder 512 along the axial direction of the fixed cylinder 512, the piston 513 drives the connecting pipe 515 to reciprocally move along 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 helical, the rotating rod 516 is driven to reciprocally rotate, the stirring blades 519 are driven to reciprocally rotate by the rotating rod 516, thereby stirring the material accumulated at the turning part of the conveying pipe 3, preventing the material from being accumulated and caked, causing the conveying pipe 3 to be blocked, and ensuring the conveying effect of the material.

[0042] Here, it is supplemented that the rolling element 517 is preferably a bull's eye ball.

[0043] The anti-blocking mechanism 5 further comprises a jetting assembly 52 for blowing the material in the conveying pipe 3; the jetting assembly 52 comprises a first capsule 521 fixedly installed in the fixed cylinder 512, an annular pipe 522 in communication with the first capsule 521, and a plurality of nozzles 525 in communication with the annular pipe 522; the nozzles 525 are annularly arranged along the circumferential direction of the annular pipe 522, and the gas outlet ends of the nozzles 525 are all insertedly installed in the conveying pipe 3.

[0044] When the piston 513 reciprocally moves in the fixed cylinder 512 along the axial direction, the first capsule 521 is driven to reciprocally compress and restore.

[0045] The first capsule 521 and the annular pipe 522 are in communication through a gas outlet pipe 524, and the first capsule 521 is further provided with a gas inlet pipe 523, and the gas inlet pipe 523 and the gas outlet pipe 524 are both provided with one-way valves, so that air enters the first capsule 521 through the gas inlet pipe 523 and is discharged through the gas outlet pipe 524.

[0046] Thus, when the first capsule 521 reciprocates compression and recovery, the air outside can be sucked into the first capsule 521 through the air inlet pipe 523, and transported to the annular pipe 522 through the air outlet pipe 524, and then sprayed out through the spray head 525, so as to blow the material accumulated at the turning part of the conveying pipe 3, prevent the material from accumulating and clogging, cause the conveying pipe 3 to be blocked, and further ensure the conveying effect of the material.

[0047] The stirring blade 519 is fixedly installed with a brush 526 on the side close to the spray head 525.

[0048] When the stirring blade 519 rotates, the brush 526 can be driven to rotate, so as to clean the spray head 525 and prevent the material from clogging the spray head 525.

[0049] The anti-blocking mechanism 5 further comprises a cooling assembly 53 for cooling the gas in the conveying pipe 3; the cooling assembly 53 comprises a cooling box 531 fixedly installed in the mounting frame 511; a cooling pipe 534 fixedly sleeved on the conveying pipe 3; the cooling box 531 is in communication with the cooling pipe 534 and the fixed cylinder 512 respectively; and the cooling pipe 534 is in communication with the fixed cylinder 512.

[0050] The cooling box 531 and the cooling pipe 534 are in communication through a liquid return pipe 535, the cooling box 531 and the fixed cylinder 512 are in communication through a liquid inlet pipe 532, and the cooling pipe 534 and the fixed cylinder 512 are in communication through a liquid outlet pipe 533.

[0051] The liquid inlet pipe 532 and the liquid outlet pipe 533 are each provided with a one-way valve, which is used to allow the cooling liquid in the cooling box 531 to pass through the liquid inlet pipe 532 into the fixed cylinder 512 in one direction only and be discharged through the liquid outlet pipe 533.

[0052] The piston 513 divides the fixed cylinder 512 into two independent spaces, one of which stores liquid above the piston 513 and the other of which stores gas below the piston 513.

[0053] When the piston 513 reciprocates in the fixed cylinder 512 along the axial direction of the fixed cylinder 512, the cooling liquid in the cooling liquid 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, and the cooling liquid in the cooling pipe 534 can cool the conveying pipe 3, so as to cool and heat the gas flow in the conveying pipe 3, and the cooled and heated cooling liquid flows into the cooling box 531 through the liquid return pipe 535, so as to recycle the cooling liquid.

[0054] By cooling and heating the gas flow in the conveying pipe 3, the risk of clogging in the conveying process caused by the high temperature that may cause some materials to become viscous or clog is avoided, and if the material is sensitive to temperature, the high temperature may cause the material to deteriorate, decompose or lose activity.

[0055] In addition, the first capsule 521 is located in the space in which the fixed cylinder 512 stores the liquid, and therefore, the cooling liquid can cool the air in the first capsule 521, so that the air sprayed by the spray head 525 to the material becomes cold air, and the cold air is more fully contacted with the material by the stirring of the stirring blade 519, thereby further avoiding the problem that high temperature can cause some materials to become sticky or caked, increase the risk of blockage in the conveying process, and avoid the problem that high temperature can cause temperature-sensitive materials to deteriorate, decompose or lose activity.

[0056] It is supplemented here that the cooling liquid in the cooling pipe 534 adopts a top-down mode, so that the cooling pipe 534 is filled with cooling liquid, thereby sufficiently cooling the airflow.

[0057] In the present application, the material is stirred by the stirring blade 519, the material is sprayed by the spray head 525, and the material is cooled by the cooling liquid, which on the one hand avoids the blockage of the material at the turning of the conveying pipe 3, and ensures the conveying effect of the material; on the other hand, the material can be cooled, which avoids the problem that high temperature can cause some materials to become sticky or caked, increase the risk of blockage in the conveying process, and the problem that high temperature can cause temperature-sensitive materials to deteriorate, decompose or lose activity.

[0058] The cooling assembly 53 further comprises a stirring unit 536 for stirring the cooling liquid in the cooling box 531; the stirring unit 536 comprises a limiting strip 5362 fixedly installed in the cooling box 531; a movable plate 5361 slidingly installed on the limiting strip 5362; and a driving member 5366 for driving the movable plate 5361 to move.

[0059] The cooling box 531 is connected with a cooling source for cooling the cooling liquid in the cooling box 531, so as to ensure the cooling effect of the cooling liquid; the cooling source is preferably a cooling unit.

[0060] The driving member 5366 drives the movable plate 5361 to move to stir the cooling liquid; the driving member 5366 comprises a fixed pipe 53661 insertedly installed on the cooling box 531; a movable pipe 53662 slidingly installed in the fixed pipe 53661; and a second capsule 53663 fixedly installed between the fixed pipe 53661 and the movable pipe 53662; the second capsule 53663 is communicated with the fixed cylinder 512 through an air guide pipe 53664.

[0061] That is, when the piston 513 reciprocates in the fixed cylinder 512 along the axial direction of the fixed cylinder 512, the air in the cavity of the fixed cylinder 512 for storing air is reciprocated to be extruded or sucked, and since the second capsule 53663 is communicated with the fixed cylinder 512 through the air guide pipe 53664, the second capsule 53663 is reciprocated to expand and restore.

[0062] Through the reciprocating expansion and restoration of the second capsule 53663, the movable pipe 53662 can be driven to reciprocate up and down, and under the limiting action of the limiting strip 5362, the movable plate 5361 can be driven to reciprocate up and down, so that vertical stirring of the cooling liquid can be realized, so that the cooling liquid generates convection in the vertical direction, promotes the mixing of the cooling liquid in the vertical direction, and makes the cold source uniformly cool the cooling liquid.

[0063] The stirring unit 536 further comprises: a mounting groove opened on the limiting strip 5362; a rack 5363 fixedly installed in the mounting groove; a connecting gear 5364 rotatably installed on the movable plate 5361; a stirring plate 5365 coaxially connected with the connecting gear 5364; and the rack 5363 and the connecting gear 5364 are in meshing arrangement.

[0064] When the movable pipe 53662 reciprocates up and down, the stirring plate 5365 and the connecting gear 5364 can be driven to move, and since the connecting gear 5364 and the rack 5363 are in meshing arrangement, when the connecting gear 5364 moves with the movable plate 5361, the connecting gear 5364 rotates, thereby driving the stirring plate 5365 to rotate. Through the rotation of the stirring plate 5365, the cooling liquid can be further stirred, the stirring range is expanded, the cooling liquid is uniformly mixed, and the cold source uniformly cools the cooling liquid.
