Description

Technical Field

[0001] This utility model relates to the field of particulate material conveying, and in particular to a structure for an anti-clogging particulate material conveying pipeline. Background Technology

[0002] In industrial production, particulate matter conveying pipelines are widely used in various production scenarios, and their operational stability is crucial to the entire production process. However, in actual use, existing particulate matter conveying pipelines frequently experience blockages, which seriously restricts production efficiency and quality. Utility Model Content

[0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a clog-resistant particulate matter conveying pipeline structure that improves conveying and unblocking efficiency, reduces the risk of blockage, and has a simple structure and a high degree of automation.

[0004] This utility model provides an anti-clogging particulate matter conveying pipeline structure, comprising: At least one conveying pipe, the diameter of which gradually increases linearly from the starting end to the end end, the end pipe diameter D2 being 1.2-1.5 times the starting end pipe diameter D1, and a feed inlet is provided at the top of the starting end of the conveying pipe; Elbows have a radius of curvature of 3-5 times the pipe diameter. One end of the elbow is provided with an upper flange that is detachably connected to the flange at the end of the conveying pipe, and the other end is provided with a lower flange that is detachably connected to the feed inlet or storage tank of the conveying pipe adjacent downstream. A fan is installed at the beginning of the conveying pipe to provide power for the movement of the particles in the conveying pipe. The unblocking mechanism is installed on the pipe wall at the end of the conveying pipe, near the bend, to clear the blockage at the bend; A vibration motor is installed on the outer wall of the elbow to clear blockages through vibration; The feeding box is connected to the feed inlet of the conveying pipe located at the starting end, and the particles therein can fall into the conveying pipe and be transported by the fan; A storage tank, connected to the lower flange, is used to hold particulate matter transported by the conveying pipe.

[0005] Furthermore, the elbow is made of hard rubber, and sealing strips are provided on the contact surfaces of the upper flange, lower flange, and the feed inlet or storage tank.

[0006] Furthermore, the unblocking mechanism includes an unblocking nozzle. Several nozzle holes are formed around the circumference of the end wall of the delivery pipe, near the bend. A nozzle box is provided on the outer wall of the delivery pipe, above the nozzle holes. One end of the unblocking nozzle is rotatably connected to the nozzle hole via a rotating shaft driven by a geared motor, causing the unblocking nozzle to rotate around it. A limiting block is fixed beside the rotating shaft. A high-pressure nozzle is provided on the side of the unblocking nozzle away from the rotating shaft. The high-pressure nozzle passes through the unblocking nozzle and the delivery pipe via a high-pressure spray pipe and is connected to a high-pressure air pump. The bottom surface of the unblocking nozzle is adapted to the inner wall of the delivery pipe. The shape of the nozzle hole is clearance-fitted with the bottom surface of the unblocking nozzle, allowing the unblocking nozzle to pass through the nozzle hole and be completely housed in the nozzle box.

[0007] Furthermore, a pressure sensor is installed on the inner wall of the elbow, and a flow sensor is installed at the feed inlet and the lower flange. The pressure sensor, flow sensor, unblocking mechanism, and vibration motor are all connected to the PLC control system.

[0008] Compared with the prior art, the beneficial effects of this utility model are: This utility model discloses an anti-clogging particulate matter conveying pipeline structure, comprising a conveying pipe, elbows, a blower, a blockage-clearing mechanism, a vibrating motor, a feeding box, and a storage box. At the beginning of the pipeline, a smaller pipe diameter allows the particles to achieve a higher flow velocity in the initial stage, quickly entering the conveying state. As the conveying process progresses, the pipe diameter gradually increases, effectively avoiding particle settling and blockage caused by a sudden decrease in flow velocity due to pressure reduction at the end of the pipeline. However, due to the increased pipe diameter, the pressure provided by the blower may be insufficient. Therefore, this conveying pipeline structure can be composed of multiple conveying pipes connected in a stepped manner, with each section powered by a matching blower. When a blockage occurs in the conveying pipe, the pressure sensor and flow sensor will display abnormal values. This data is transmitted to the PLC control system, which controls the blockage-clearing nozzle to spray high-pressure airflow in a pulsed manner towards the blockage, and activates the vibrating motor to vibrate at a specific frequency and amplitude, causing the particles in the pipeline to resonate, further enhancing the blockage-clearing effect and ensuring that the blocked particles are completely removed, restoring normal conveying. This conveying pipeline structure improves conveying and unblocking efficiency, reduces the risk of blockage, has a simple structure, and a high degree of automation.

Detailed Implementation

[0011] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0012] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0013] Please refer to Figures 1-7 An embodiment of this utility model provides an anti-clogging particulate matter conveying pipeline structure, comprising: At least one conveying pipe 1, the diameter of the conveying pipe 1 gradually increases linearly from the starting end to the end end, the end pipe diameter D2 is 1.2-1.5 times the starting end pipe diameter D1, and the top of the starting end of the conveying pipe 1 is provided with a feed inlet 11; Elbow 2 has a radius of curvature that is 3-5 times the diameter of the pipe. One end of it is provided with an upper flange 21, which is detachably connected to the flange at the end of the conveying pipe 1. The other end is provided with a lower flange 22, which is detachably connected to the feed inlet 11 or storage box 7 of the adjacent conveying pipe 1 downstream. Fan 3 is located at the beginning of conveying pipe 1 and is used to provide power to move the particles in conveying pipe 1. The unblocking mechanism 4 is installed on the pipe wall at the end of the conveying pipe 1, near the bend 2, and is used to clear the blockage at the bend 2; Vibration motor 5 is installed on the outer wall of elbow 2 to clear blockages through vibration; The feeding box 6 is connected to the inlet 11 of the conveying pipe 1 located at the starting end, and the particles therein can fall into the conveying pipe 1 and be transported by the fan 3. Storage tank 7, connected to lower flange 22, is used to hold particulate matter transported by conveying pipe 1.

[0014] In this embodiment, at the beginning of the conveying pipe 1, the smaller pipe diameter allows the particles to achieve a higher flow velocity in the initial stage and quickly enter the conveying state. As the conveying process progresses, the pipe diameter gradually increases, which effectively avoids the problem of particle settling and blockage caused by a sudden decrease in flow velocity due to a drop in pressure at the end of the pipe. However, due to the increase in pipe diameter, the pressure provided by the blower 3 is insufficient. Therefore, this conveying pipe structure can be composed of multiple conveying pipes connected in a stepped manner, with each section of the conveying pipe having a matching blower 3 to provide power. When a blockage occurs in the conveying pipe 1, the unblocking mechanism 4 can be activated to spray high-pressure airflow in the form of pulses at the blockage, and the vibration motor 5 can be turned on to vibrate at a specific frequency and amplitude to make the particles in the pipe resonate, further enhancing the unblocking effect and ensuring that the blocked particles in the pipe can be completely removed and normal conveying can be restored. This conveying pipe structure improves the conveying and unblocking efficiency, reduces the risk of blockage, and has a simple structure.

[0015] In a preferred embodiment, the elbow 2 is made of hard rubber, and sealing strips are provided on the contact surfaces of the upper flange 21, the lower flange 22 and the feed port 11 or the storage tank 7. The elbow 2 made of hard rubber will not wear out too quickly, and it also buffers the impact of particles. The elbow 2 can be removed and inspected separately, saving disassembly and assembly time. When the wear is too great, it can be quickly replaced, which improves production efficiency.

[0016] In a preferred embodiment, such as Figures 3-7As shown, the unblocking mechanism 4 includes an unblocking nozzle 43. Several nozzle holes 42 are provided around the end of the pipe wall of the delivery pipe 1, near the bend 2. A nozzle box 41 is provided on the outer wall of the delivery pipe 1 above the nozzle holes 42. One end of the unblocking nozzle 43 is rotatably connected to the nozzle hole 42 via a rotating shaft 45. The rotating shaft 45 is driven by a reduction motor 48, which drives the unblocking nozzle 43 to rotate around it. A limiting block 44 is fixed next to the rotating shaft 45. A high-pressure nozzle 47 is provided on the side of the unblocking nozzle 43 away from the rotating shaft 45. The high-pressure nozzle 47 passes through the unblocking nozzle 43 and the delivery pipe 1 through a high-pressure nozzle pipe 46 and is connected to a high-pressure air pump. The bottom surface of the unblocking nozzle 43 is adapted to the inner wall of the delivery pipe 1. The shape of the nozzle hole 42 is clearance-fitted with the bottom surface of the unblocking nozzle 43, so that the unblocking nozzle 43 can pass through the nozzle hole 42 and be completely stored in the nozzle box 41.

[0017] In this embodiment, when there is no blockage in the conveying pipe 1, the unblocking nozzle 43 is completely housed in the nozzle box 41 and will not obstruct the conveying of particles; when a blockage occurs at the elbow 2, the feeding of the feeding box 6 is stopped, and the unblocking nozzle 43 is driven down by the reduction motor 48 and stops at the limit block 44. The high-pressure air pump generates pulse airflow, which passes through the high-pressure nozzle 46 and is sprayed out from the high-pressure nozzle 47. The impact force of the airflow can blow away the accumulated particles, achieving the effect of clearing the blockage and improving the conveying and unblocking efficiency.

[0018] In a preferred embodiment, a pressure sensor is installed on the inner wall of the elbow 2, and flow sensors are installed at the feed inlet 11 and the lower flange 22. The pressure sensor, flow sensor, unblocking mechanism 4, and vibration motor 5 are all connected to the PLC control system. When a blockage occurs in the conveying pipe, the pressure sensor and flow sensor will display abnormal values. After this data is transmitted to the PLC control system, the PLC will control the unblocking mechanism 4 and vibration motor 5 to work together, thereby improving the automation and conveying efficiency of the structure.
