Abstract
Description
Technical Field
[0001] This utility model belongs to the field of feldspar powder production technology, and specifically relates to a feeding pipe structure for material feeding. Background Technology
[0002] In the production process of feldspar powder, the feed pipe is a key conveying component connecting crushing, grinding, screening and other processes. Its core function is to stably and efficiently transport the feldspar powder particles produced by the upstream equipment to downstream silos, crushers or conveyor belts and other equipment.
[0003] The current announcement of Chinese utility model patent CN220484331U discloses a discharge pipe for high-altitude material discharge. It is equipped with a discharge pipe and a feeding hopper. In use, the feeding hopper is sealed to an opening on the end housing of a belt conveyor. This allows albite powder to fall into the feeding hopper after being conveyed by the belt conveyor. As the powder continues to fall, its height increases until it surpasses the bottom opening of the discharge pipe. The powder then exits through an array of openings distributed along the axis of the discharge pipe. Because of the increased height of the powder, the distance between it and the discharge openings decreases, thus reducing the falling height of the powder, further reducing dust generated by the falling powder, improving the production environment, and reducing powder waste.
[0004] Although this patent can reduce the falling height of powder and reduce dust, the falling height of feldspar powder during production is 1-1.5 meters, resulting in a relatively long falling pipe, which makes it inconvenient to clean the inner wall of the falling pipe. Utility Model Content
[0005] The purpose of this utility model is to provide a material discharge pipe structure that solves the problem of the existing high-level material discharge pipe, which is too long and inconvenient for cleaning the inner wall of the material discharge pipe when the material discharge height is 1-1.5 meters during feldspar powder production.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a material feeding pipe structure, including an inner pipe and an outer pipe, wherein the inner pipe is located inside the outer pipe, the upper end of the inner pipe is provided with a material inlet, the upper end of the inner pipe is provided with a rinsing mechanism, and the lower end of the inner pipe is provided with a pneumatic mechanism. The showering mechanism includes a showering chamber, showering holes, and a water inlet pipe. The showering chamber is located inside the upper end of the inner tube. The showering holes are located on the showering chamber and are evenly distributed. The water inlet pipe is located on the showering chamber.
[0007] Using the above technical solution, by setting up an inner pipe, an outer pipe, a feed inlet, a rinsing mechanism, and a pneumatic mechanism, the outer pipe supports and protects the inner pipe during use, preventing damage. Feldspar powder is then fed into the inner pipe through the feed inlet for conveying. The pneumatic mechanism prevents the feldspar powder from clogging the lower end of the inner pipe. After use, the inner pipe is evenly rinsed by the rinsing mechanism; continuous rinsing removes impurities from the inner wall. After drying, the inner pipe can be reused. The rinsing mechanism includes a rinsing chamber, rinsing holes, and a water inlet pipe. After the feldspar powder is conveyed, clean water is injected into the rinsing chamber through the water inlet pipe, and then the clean water is discharged into the inner wall of the inner tube through the rinsing holes. Since there are several rinsing holes evenly distributed, the clean water can flow evenly on the inner wall of the inner tube. Through continuous rinsing, the feldspar powder adhering to the inner wall of the inner tube can be cleaned away. After the inner tube is dried, it can be used again, avoiding the problem of the inner wall becoming increasingly caked after long-term use, which would reduce the conveying effect.
[0008] Furthermore: the pneumatic mechanism includes a wind cavity, a fan, and a duct. The wind cavity is located at the lower end of the inner tube, the fan is mounted on the wind cavity, the output end of the fan is located inside the wind cavity, one end of the duct passes through the wind cavity, and the other end of the duct extends into the interior of the inner tube. The duct is inclined downward.
[0009] By adopting the above technical solution, by setting up an air cavity, a fan and an air duct, the fan can blow air into the air cavity during use, and then blow the air into the inner tube through the air duct. Since the air duct is set at an angle downward, the airflow blows the feldspar powder downward, providing a downward force and avoiding feldspar powder blockage after the diameter of the third tube body is reduced.
[0010] Furthermore: the inner tube is composed of a first tube body, a second tube body, and a third tube body, the inner diameters of the first tube body, the second tube body, and the third tube body decrease sequentially, and the connection points of the first tube body and the second tube body, and the second tube body and the third tube body are inclined.
[0011] By adopting the above technical solution, a three-section structure with progressively decreasing inner diameters—the first, second, and third pipes—is used to achieve gradient flow rate control, avoiding conflicts between material blockage and material flow. When feldspar powder enters the first pipe from the upstream equipment, the initial flow rate is relatively slow, preventing turbulent airflow within the pipe due to excessive flow rate. Upon entering the second pipe, spatial compression naturally increases the material flow rate, effectively breaking down electrostatic and adhesive forces between particles and preventing the accumulation of fine feldspar powder within the pipe. Finally, upon entering the third pipe, the flow rate is maintained within a stable range that meets the feeding requirements of the downstream equipment. The inclined connection eliminates dead zones at the pipe joints, blocking bridging paths.
[0012] Furthermore: the upper end of the inner tube is provided with an installation groove, the bottom of the installation groove is provided with a magnetic ring, a baffle is provided in the installation groove, the baffle is configured to cooperate with the shower hole, and the lower end of the baffle is made of magnetic material.
[0013] By adopting the above technical solution, by setting up an installation groove, a magnetic ring and a baffle, when conveying feldspar powder, the baffle is placed into the installation groove and fixed by the magnetic ring to avoid the feldspar powder from clogging the flushing holes. When rinsing the inner tube, the baffle is removed upward by friction to expose the flushing holes.
[0014] Furthermore, a connecting rod is provided between the inner tube and the outer tube, and the number of the connecting rods is several and evenly distributed.
[0015] By adopting the above technical solution and setting a connecting rod, the inner tube can be fixed on the outer tube during use, thereby improving the stability of the inner tube and preventing it from shaking.
[0016] Furthermore, the inner wall of the baffle is provided with anti-slip grooves, and the number of anti-slip grooves is several and arranged in a circle.
[0017] By adopting the above technical solution and setting anti-slip grooves, the anti-slip grooves can increase the friction between the staff and the baffle during use, making it easier for the staff to remove the baffle.
[0018] Furthermore, the upper end of the baffle is inclined downwards.
[0019] By adopting the above technical solution, the upper end of the baffle is tilted downwards, which can prevent feldspar powder from accumulating at the upper end of the baffle.
[0020] Furthermore: the outer tube is made of rigid carbon steel, and the inner wall of the inner tube is smooth.
[0021] By adopting the above technical solution, the material of the outer tube is set. Rigid carbon steel has high strength and deformation resistance, which can provide a stable frame support for the entire tube body. The smooth inner wall can significantly reduce the friction coefficient between feldspar powder and the tube wall, avoiding slowdown in flow rate and material accumulation due to excessive friction resistance.
[0022] In summary, this utility model has the following beneficial effects: By setting up a rinsing mechanism, after the feldspar powder is transported, clean water is injected into the rinsing chamber through the water inlet pipe, and then the clean water is discharged into the inner wall of the inner tube through the rinsing holes. Since the number of rinsing holes is several and evenly arranged, the clean water can flow evenly on the inner wall of the inner tube.
[0023] By setting up a pneumatic mechanism, the fan can blow air into the air cavity during use, and then blow the air into the inner tube through the air duct. Since the air duct is set at an angle downward, the airflow blows the feldspar powder downward, providing a downward force and preventing feldspar powder from clogging the third tube after its diameter is reduced.
[0024] Based on the above improvements, the overall technical effect achieved by this device is that it can clean the feldspar powder adhering to the inner wall of the inner tube through continuous rinsing, and then the inner tube can be used again after drying. This avoids the problem that the inner wall of the inner tube will become more and more serious due to long-term use, which will reduce the conveying effect. Attached Figure Description

Detailed Implementation
[0027] The present invention will be further described in detail below with reference to the accompanying drawings.
[0028] Example: Please see Figures 1-6 The present invention provides a technical solution: a material feeding pipe structure, including an inner pipe 1 and an outer pipe 2, the inner pipe 1 being located inside the outer pipe 2, the upper end of the inner pipe 1 being provided with a material inlet 3, the upper end of the inner pipe 1 being provided with a rinsing mechanism 4, and the lower end of the inner pipe 1 being provided with a pneumatic mechanism 5. The showering mechanism 4 includes a showering chamber 401, a showering hole 402, and a water inlet pipe 403. The showering chamber 401 is located inside the upper end of the inner tube 1. The showering hole 402 is located on the showering chamber 401. The number of showering holes 402 is several and they are evenly arranged. The water inlet pipe 403 is located on the showering chamber 401.
[0029] By configuring an inner tube 1, an outer tube 2, an inlet 3, a rinsing mechanism 4, and a pneumatic mechanism 5, the outer tube 2 supports and protects the inner tube 1 during use, preventing damage. Feldspar powder is then fed into the inner tube 1 through the inlet 3. The pneumatic mechanism 5 prevents the feldspar powder from clogging the lower end of the inner tube 1. After use, the inner tube 1 is evenly rinsed by the rinsing mechanism 4. Continuous rinsing removes impurities from the inner wall of the inner tube 1. After drying, the inner tube 1 can be reused. The rinsing mechanism 4 includes a rinsing chamber. 401, rinsing holes 402 and water inlet pipe 403: After the feldspar powder is conveyed, clean water is injected into the rinsing chamber 401 through the water inlet pipe 403, and then the clean water is discharged into the inner wall of the inner tube 1 through the rinsing holes 402. Since there are several rinsing holes 402 and they are evenly arranged, the clean water can flow evenly on the inner wall of the inner tube 1. Through continuous rinsing, the feldspar powder attached to the inner wall of the inner tube 1 can be cleaned. After the inner tube 1 is dried, it can be used again, avoiding the problem that the inner wall of the inner tube 1 will become more and more serious due to long-term use, which will reduce the conveying effect.
[0030] refer to Figure 6 The pneumatic mechanism 5 includes a wind chamber 501, a fan 502, and a duct 503. The wind chamber 501 is located at the lower end of the inner tube 1. The fan 502 is mounted on the wind chamber 501, and the output end of the fan 502 is located inside the wind chamber 501. One end of the duct 503 passes through the wind chamber 501, and the other end of the duct 503 extends into the interior of the inner tube 1. The duct 503 is inclined downward. By setting up the wind chamber 501, the fan 502, and the duct 503, during use, the fan 502 can blow airflow into the wind chamber 501, and then blow the airflow into the inner tube 1 through the duct 503. Since the duct 503 is inclined downward, the airflow blows the feldspar powder downward, providing a downward force and preventing feldspar powder blockage after the diameter of the third tube 8 decreases.
[0031] refer to Figure 4The inner pipe 1 consists of a first pipe body 6, a second pipe body 7, and a third pipe body 8. The inner diameters of the first pipe body 6, the second pipe body 7, and the third pipe body 8 decrease sequentially. The connection points of the first pipe body 6 and the second pipe body 7, and the second pipe body 7 and the third pipe body 8 are inclined. By setting the first pipe body 6, the second pipe body 7, and the third pipe body 8, and through the three-section structure with the inner diameter decreasing sequentially, the flow rate gradient can be controlled to avoid the contradiction between material blockage and material rushing. When the feldspar powder enters the first pipe body 6 from the upstream equipment, the initial flow rate is relatively slow, which can avoid the airflow turbulence in the pipe caused by the excessive flow rate. After entering the second pipe body 7, the space compression causes the material flow rate to increase naturally, which can effectively break the electrostatic force and adhesion between particles and prevent fine feldspar powder from accumulating in the pipe. Finally, when entering the third pipe body 8, the flow rate is maintained in a stable range that matches the feeding requirements of the downstream equipment. The inclined connection eliminates the dead corners of accumulation at the pipe body connection and blocks the path of bridging.
[0032] refer to Figure 5 An installation groove 9 is provided at the upper end of the inner tube 1. A magnetic ring 10 is provided at the bottom of the installation groove 9. A baffle 11 is provided inside the installation groove 9. The baffle 11 is configured to cooperate with the rinsing hole 402. The lower end of the baffle 11 is made of magnetic material. By setting up the installation groove 9, the magnetic ring 10 and the baffle 11, when conveying feldspar powder, the baffle 11 is placed into the installation groove 9 and fixed by the magnetic ring 10 to prevent the feldspar powder from clogging the rinsing hole 402. When rinsing the inner tube 1, the baffle 11 is lifted upward by friction to expose the rinsing hole 402.
[0033] refer to Figure 4 A connecting rod 12 is provided between the inner tube 1 and the outer tube 2. The number of connecting rods 12 is several and they are evenly distributed. By providing the connecting rod 12, the inner tube 1 can be fixed on the outer tube 2 during use, thereby improving the stability of the inner tube 1 and preventing the inner tube 1 from shaking.
[0034] refer to Figure 5 The inner wall of the baffle 11 is provided with anti-slip grooves 13. There are several anti-slip grooves 13 arranged in a circle. By setting the anti-slip grooves 13, the anti-slip grooves 13 can increase the friction between the staff and the baffle 11 during use, so that the staff can take out the baffle 11 more easily.
[0035] refer to Figure 1 The upper end of the baffle 11 is inclined downwards. By inclining the upper end of the baffle 11 downwards, feldspar powder can be prevented from accumulating on the upper end of the baffle 11.
[0036] refer to Figure 4The outer tube 2 is made of rigid carbon steel, and the inner wall of the inner tube 1 is smooth. By choosing the material of the outer tube 2, the rigid carbon steel has high strength and deformation resistance, which can provide a stable frame support for the entire tube body. The smooth inner wall can significantly reduce the friction coefficient between feldspar powder and the tube wall, avoiding slowing down the flow rate and material accumulation due to excessive friction resistance.
[0037] Brief description of usage: In operation, the outer pipe 2 first supports and protects the inner pipe 1, preventing damage. Then, feldspar powder enters the inner pipe 1 through the inlet 3 for conveying. The three-section structure with progressively decreasing inner diameters allows for gradient flow rate control, preventing material blockage and overflow. When the feldspar powder enters the first pipe 6 from the upstream equipment, the initial flow rate is slow, avoiding turbulent airflow caused by excessive velocity. After entering the second pipe 7, spatial compression naturally increases the material flow rate, effectively breaking down electrostatic forces and adhesion between particles. The flow rate is maintained within a stable range that meets the feeding requirements of downstream equipment when the flow finally enters the third pipe body 8. The oblique connection eliminates the dead corners at the pipe body joints and blocks the bridging path. The blower 502 can blow air into the air chamber 501 and then blow air into the inner pipe 1 through the air duct 503. Since the air duct 503 is set at an angle downward, the airflow blows the feldspar powder downward, providing a downward force and preventing feldspar powder blockage after the diameter of the third pipe body 8 is reduced. Then, after the feldspar powder is conveyed, clean water is injected into the rinsing chamber 401 through the water inlet pipe 403, and then the clean water is discharged into the inner wall of the inner tube 1 through the rinsing holes 402. Since there are several rinsing holes 402 and they are evenly arranged, the clean water can flow evenly on the inner wall of the inner tube 1. Through continuous rinsing, the feldspar powder attached to the inner wall of the inner tube 1 can be cleaned. After the inner tube 1 is dried, it can be used again, avoiding the problem that the inner wall of the inner tube 1 will become more and more serious due to long-term use, which will reduce the conveying effect. When conveying feldspar powder, the baffle 11 is placed into the installation groove 9 and fixed by the magnetic ring 10 to prevent the feldspar powder from clogging the rinsing holes 402. When rinsing the inner tube 1, the baffle 11 is taken out upward by friction to expose the rinsing holes 402. Finally, the connecting rod 12 can fix the inner tube 1 to the outer tube 2, improve the stability of the inner tube 1, and prevent the inner tube 1 from shaking. The anti-slip groove 13 can increase the friction between the worker and the baffle 11, and enable the worker to take out the baffle 11 more easily.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
