Abstract
Description
Technical Field
[0001] This invention relates to the field of material conveying equipment technology, and in particular to an air chute conveying system and its conveying method. Background Technology
[0002] Existing material transport air chute technologies are mainly used in two aspects: firstly, to transport powdery or granular materials from a high position to a low position, and secondly, to transport powdery or granular materials from a low position to a high position. Currently, transporting powdery or granular materials from a low position to a high position uses a motor-driven screw conveyor to deliver the material to its destination; while transporting powdery or granular materials from a high position to a low position mostly uses a double-chute configuration, where an air duct is set below the material chute. Wear-resistant synthetic fiber is used as a breathable layer between the material chute and the air duct. A centrifugal fan is installed at the relatively higher horizontal port of the air duct. Utilizing natural wind, the air force blows the powdery or granular materials in the material chute through the breathable layer, causing them to roll down the material chute and achieve the purpose of transportation.
[0003] Existing air chute conveying devices often experience air outlet blockage during use, leading to material accumulation and hindering the effective airflow of powder materials, thus affecting the material conveying efficiency.
[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the Invention
[0005] To address the aforementioned deficiencies, the present invention aims to provide an air chute conveying system and its conveying method. This system can automatically clean the air outlet of the air chute by setting a structure that can automatically clean the blocked air outlet when the air chute becomes blocked, thereby ensuring the airflow supply effect of the material and the reliability of the conveying.
[0006] To achieve the above objectives, the present invention provides an air chute conveying system, comprising: a feeding pipe having a feeding channel inside, and a feeding inlet on one side of the feeding channel; An air supply pipe has an internal air supply channel. An air chute is provided between the air supply channel and the feeding channel. The air chute includes two fixedly installed air inlet vent plates and air outlet vent plates. Several control components are provided on the air inlet vent plates. When the control components detect that the air holes on the air outlet vent plates are blocked, they clear the air holes. The control component includes a slider, and the top of the slider is provided with a clearing shaft corresponding to the air hole, the clearing shaft clearing the blocked air hole.
[0007] In one embodiment, the air intake vent plate is provided with a plurality of air inlets, and a plurality of baffle plates are provided between the air intake vent plate and the air outlet vent plate. The plurality of baffle plates form a partition corresponding to the air inlets, and each partition is provided with an air inlet and a plurality of air holes.
[0008] In one embodiment, the top of the sliding member is provided with a sliding plate that is slidably connected to the inside of the partition, and the unblocking shaft is fixed on the sliding plate and is configured to correspond to the air hole in the partition.
[0009] In one embodiment, the control component includes: A fixed sleeve is fixedly connected to the bottom of the air inlet, the sliding member is slidably connected to the inside of the fixed sleeve, the inside of the sliding member is provided with a gas channel, the outer wall of the unblocking shaft is provided with a strip-shaped through hole, and the gas channel communicates with the side wall of the strip-shaped through hole; A control block is slidably connected to the inner wall of the gas channel. When gas is supplied inside the gas channel, the control block retracts into the inner wall of the sliding member. When the gas is not flowing inside the gas channel, the control block extends to block the gas channel.
[0010] In one embodiment, the inner wall of the gas channel is provided with a groove, the control block is slidably connected to the inside of the groove, and a thrust spring is provided between the control block and the groove.
[0011] In one embodiment, the control block includes a sliding column slidably connected inside the groove and a sealing block disposed on the sliding column. The sealing block is provided with a guide bevel, and the gas passage is sealed when the front ends of the two sealing blocks abut against each other.
[0012] In one embodiment, the sliding plate has an airflow space inside, and a balance hole connecting the sliding groove and the airflow space is provided between the two. The airflow space is connected to the strip-shaped through hole.
[0013] In one embodiment, the bottom of the sliding member is provided with a sliding shaft, the sliding shaft is slidably connected to the inside of the fixed sleeve, the inside of the fixed sleeve is provided with a first limiting flange, the sliding shaft is provided with a second limiting flange, and a return spring is provided between the first limiting flange and the second limiting flange.
[0014] In one embodiment, the contact surfaces of the air supply pipe and the feeding pipe are provided with an installation groove and an installation protrusion. The installation groove and the installation protrusion press the air chute between the air supply pipe and the feeding pipe. The top of the air supply pipe is provided with an air inlet. The air supply pipe and the feeding pipe are installed and fixed by the installation part.
[0015] The present invention also provides a conveying method, comprising the following steps: S1. Material is injected into the feed pipe from the inlet, and high-pressure gas is supplied into the air supply pipe from the inlet. S2. High-pressure gas acts on the control block, and the control block slides into the inside of the chute under the action of air thrust, ensuring that the gas enters the inside of the feeding pipe through the air hole after the gas channel. S3. When the air hole in the corresponding partition is blocked, the air pressure on the upper and lower sides of the control block is the same. At this time, the gas pressure inside the balance hole is the same as the gas pressure inside the gas channel and reaches a balance. After the two ends of the control block are balanced and pressed tightly, the gas channel is blocked. The sliding part moves upward under the gas thrust, so that the unblocking shaft unblocks the air hole. S4. After the air hole is cleared, the gas pressure inside the balance hole decreases. Then, the gas pushes the control block to slide into the groove. The sliding part is then reset by the force of the return spring.
[0016] The present invention provides an air chute conveying system, comprising: a feeding pipe having a feeding channel inside, and a feeding port on one side of the feeding channel for injecting powder material into the feeding pipe through the feeding port to facilitate the subsequent feeding process; An air supply pipe has an internal air supply channel that supplies gas to the inside of the air supply pipe. An air chute is then installed between the air supply channel and the feeding channel. The gas inside the air supply channel enters the inside of the feeding pipe through the air chute, thereby effectively realizing the pneumatic transport of powdered materials inside the feeding pipe. The air chute includes two layers of fixedly installed air inlet and air outlet plates. Several control components are installed on the air inlet plate. When the control components detect that the air holes on the air outlet plate are blocked, they clear the air holes to prevent material accumulation inside the feeding pipe from affecting the material conveying effect due to blockage. The control component includes a sliding member, the top of which is provided with a clearing shaft corresponding to the air hole. The clearing shaft clears the blocked air hole, thereby ensuring that the material blocked in the air hole can be pushed into the inside of the feeding pipe under the action of the clearing shaft. In summary, the technical effect of the present invention is to provide a structure that can automatically clean the air outlet of the air chute, ensuring that the blocked air outlet can be automatically cleaned when the air chute is blocked, thereby ensuring the airflow supply effect of the material and ensuring the reliability of the conveying.

[0021] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides an air chute conveying system, which includes a feeding pipe 1, which has a feeding channel 2 inside. A feeding port 11 is provided on one side of the feeding channel 2. Powder material is injected into the feeding pipe 1 through the feeding port 11 to facilitate the subsequent feeding process. An air supply pipe 5 has an internal air supply channel 6, through which gas is supplied to the interior of the air supply pipe 5. An air supply port 51 is provided at the bottom of the air supply pipe to ensure the normal air supply effect of the air supply pipe. An air chute 3 is provided between the air supply channel 6 and the feeding channel 2. The gas inside the air supply channel 6 enters the interior of the feeding pipe 1 through the air chute 3, thereby effectively realizing the pneumatic transport of powder materials inside the feeding pipe 1 by the air supply chute. The air chute includes two air permeable plates 34. The air permeable plates 34 include two layers of fixedly installed air inlet air permeable plates and air outlet air permeable plates. Several control components 4 are provided on the air inlet air permeable plates. When the control components 4 detect that the air hole 33 on the air outlet air permeable plate is blocked, they clear the air hole 33 to prevent the material inside the feeding pipe 1 from accumulating due to the blockage of the air hole 33, which would affect the material conveying effect. The control component 4 includes a sliding member, and the top of the sliding member is provided with a clearing shaft 423 corresponding to the air hole 33. The clearing shaft 423 clears the blocked air hole 33, thereby ensuring that the material blocked in the air hole 33 can be pushed into the inside of the feeding pipe 1 under the action of the clearing shaft 423.
[0022] In one embodiment, see Figures 4-9To ensure proper ventilation of the air chute 3, several air inlets 31 are provided on the air inlet vent plate, and several baffle plates 32 are provided between the air inlet vent plate and the air outlet vent plate. These baffle plates form partitions corresponding to the air inlets 31. Each partition has one air inlet 31 and multiple air holes 33, ensuring that air is supplied to multiple air holes 33 through a single air inlet 31, thereby effectively supplying gas to the inside of the feeding pipe 1. This causes the powder material to form an air film, thus effectively ensuring the material conveying effect. The top of the sliding component has a sliding plate 42 slidably connected to the inside of the partition. A clearing shaft 423 is fixed on the sliding plate 42 and is correspondingly set to the air hole 33 in the partition. This ensures that when the air hole 33 is blocked, the clearing shaft 423 directly pushes out the blockage inside the air hole 33, thereby effectively ensuring the unobstructed flow of the air hole 33.
[0023] Furthermore, to ensure control of the slider, control component 4 includes: A fixed sleeve 41 is fixedly connected to the bottom of the air inlet 31. A sliding member is slidably connected to the inside of the fixed sleeve 41. The inside of the sliding member is provided with a gas channel. The outer wall of the unblocking shaft 423 is provided with a strip-shaped through hole. The gas channel is connected to the side wall of the strip-shaped through hole. This ensures that when the unblocking shaft 423 unblocks the air hole 33, the unblocking shaft 423 passes through the air hole 33, and the strip-shaped through hole passes through the air hole 33, supplying air to the inside of the feeding pipe 1. This keeps the gas inside the strip-shaped through hole in a flowing state, ensuring that the air pressure inside the strip-shaped through hole is lower than that inside the gas channel. This ensures that the control block 45 can be pushed open by the air pressure, so that the sliding member is reset under the action of the reset spring 43. A control block 45 is slidably connected to the inner wall of the gas channel. When gas is supplied inside the gas channel, the control block 45 retracts into the inner wall of the sliding member. When the gas does not flow inside the gas channel, it extends to block the gas channel. The inner wall of the gas channel is provided with a sliding groove. The control block 45 is slidably connected to the inside of the sliding groove. A thrust spring 44 is provided between the control block 45 and the sliding groove, thereby realizing automatic unblocking of the blocked air hole 33. After the air hole 33 is unblocked, the sliding member can be reset, thus achieving the effect of automatic unblocking and reset.
[0024] Specifically, to ensure the installation of the control block 45, the control block 45 includes a sliding column 451 slidably connected inside the slide groove and a sealing block set on the sliding column 451. The sealing block is provided with a guide bevel 452 to ensure that high-pressure gas can act on the bevel of the guide wire, generating an outward pushing force on the sealing block, thereby ensuring that the sealing block is pushed. When the front ends of the two sealing blocks abut against each other, the gas passage is sealed. The sliding plate 42 is provided with an airflow space 422 inside. A balance hole 421 connecting the slide groove and the airflow space 422 is provided. The airflow space 422 is connected to the strip-shaped through hole. By setting the balance hole 421, the gas pressure of the airflow space 422 can be transmitted into the interior of the balance hole 421, thereby ensuring that the gas pressure on both sides of the control block 45 can be adjusted, and further adjusting the position of the control block 45.
[0025] Further, see Figure 5 , Figure 6 , Figure 7 and Figure 8 The sliding component of the present invention has a sliding shaft at its bottom, which is slidably connected to the inside of the fixed sleeve 41. The fixed sleeve 41 has a first limiting flange inside, and the sliding shaft has a second limiting flange. A return spring 43 is provided between the first limiting flange and the second limiting flange. The contact surfaces of the air supply pipe 5 and the feeding pipe 1 are provided with a mounting groove 12 and a mounting protrusion 52. The mounting groove 12 and the mounting protrusion 52 press the air inclined groove 3 between the air supply pipe 5 and the feeding pipe 1. The top of the air supply pipe 5 is provided with an air inlet 31. The air supply pipe 5 and the feeding pipe 1 are installed and fixed by the mounting part 13, thereby ensuring the normal use of the air supply pipe 5.
[0026] The present invention also provides a conveying method, combined with Figures 1-9 This includes the following steps: S1. Material is injected into the inside of the feeding pipe 1 from the inlet 11, and high-pressure gas is supplied into the inside of the air supply pipe 5 from the air inlet 31. S2. High-pressure gas acts on the control block 45. The control block 45 slides into the inside of the chute under the action of air thrust, and ensures that the gas enters the inside of the feeding pipe 1 through the air hole 33 after the gas channel. S3. When the air hole 33 in the corresponding partition is blocked, the air pressure on the upper and lower sides of the control block 45 is the same. At this time, the gas pressure inside the balance hole 421 is the same as the gas pressure inside the gas channel and reaches a balance. After the control block 45 is balanced by the force at both ends and is pressed tightly, it blocks the gas channel. The sliding part moves upward under the gas thrust, so that the unblocking shaft 423 unblocks the air hole 33. S4. After the air hole 33 is cleared, the gas pressure inside the balance hole 421 decreases. Then, the gas pushes the control block 45 to slide into the groove. The sliding part is then reset by the force of the return spring 43.
[0027] Of course, the present invention may have other various embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and modifications according to the present invention, but these corresponding changes and modifications should all fall within the protection scope of the appended claims.
