Description

Technical Field

[0001] This invention relates to the field of pneumatic ash conveying technology, and in particular to an adaptive anti-clogging ash conveying pipeline. Background Technology

[0002] Pneumatic ash conveying pipelines are widely used for closed conveying of industrial powder materials. Among them, the horizontal straight pipe section is a high-incidence area for powder deposition and pipe blockage failure. Due to the gravity of the powder itself, it is very easy to form a deposition layer at the bottom of the pipeline, which gradually thickens as the operating time extends, eventually forming powder bridging and complete pipe blockage, resulting in conveying interruption, unplanned shutdown of the production line, and extremely high equipment maintenance and production loss costs.

[0003] Existing anti-clogging technologies for straight ash conveying pipe sections have the following insurmountable core defects: Passive unblocking technologies, such as external rapping devices and bypass backflushing devices, require manual or timed activation after a blockage occurs, making it impossible to predict and intervene before blockage occurs. During the unblocking process, it is easy to cause interruption of supply and waste of high-pressure gas source. Furthermore, frequent rapping can lead to cracking of pipe welds and accelerated wear of pipe walls, significantly shortening the service life of the pipeline.

[0004] Fixed structure active anti-clogging technology, such as fixed guide vanes and sizing baffles, can suppress powder deposition to a certain extent by optimizing the flow field. However, these structures are fixed in the flow channel all year round, which continuously increases the conveying pressure loss and system energy consumption. Moreover, they cannot adjust the anti-clogging parameters according to the real-time changes in powder concentration, conveying pressure, and airflow velocity. When the operating conditions fluctuate, the anti-clogging effect drops sharply and cannot adapt to the ash conveying needs of a wide range of operating conditions.

[0005] Adjustable anti-clogging structure: There are a small number of existing adjustable flow guiding anti-clogging structures, which generally suffer from poor synchronization of the transmission mechanism and low adjustment accuracy; moreover, the core transmission components are directly exposed to a high dust environment, and dust is very likely to enter the threads and mating surfaces, causing caking, jamming, and abnormal wear, which eventually leads to the complete failure of the adjustment mechanism. The maintenance-free period is extremely short and cannot meet the needs of long-term continuous operation in industrial sites. Summary of the Invention

[0006] The main objective of this invention is to provide an adaptive anti-clogging ash conveying pipeline, which can effectively solve the problems of existing horizontal straight ash conveying pipe sections where powder easily deposits and clogs the pipe, passive cleaning is inefficient and damages the pipe, fixed anti-clogging structures have high energy consumption and poor adaptability to working conditions, adjustable structures are prone to jamming and failure, and cannot be adaptively adjusted in real time.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An adaptive anti-clogging ash conveying pipeline includes a pipeline body, an adjustment mechanism, and two wind-blocking mechanisms symmetrically arranged inside the pipeline body. Each wind-blocking mechanism includes two symmetrically arranged wind-blocking components with a reset structure. The two wind-blocking components adjust the range of air inlet or outlet by rotation. The adjustment mechanism includes an adjustment component for driving the two wind-blocking mechanisms to operate in opposite directions and two auxiliary components for cleaning and guiding the transmission structure in the adjustment component. A multi-source sensing monitoring unit wirelessly connected to the adjustment component is provided inside the pipeline body.

[0008] Preferably, the windbreak assembly includes a windbreak plate, one end of which has an arc-shaped groove, and both sides of the bottom have arc-shaped side grooves. The windbreak plates of the two windbreak assemblies are fitted together by rotation. When the two windbreak plates on the same side are fitted together by rotation, the arc-shaped groove and the arc-shaped side groove are matched with each other to form a closed limiting structure, which avoids excessive rotation and ensures the sealing when fitted, and accurately controls the flow area.

[0009] Preferably, the windbreak assembly further includes a fixed shaft rotatably connected to the main body of the pipe, and two limiting blocks and two torsion springs sleeved on the outer wall of the fixed shaft. Two fixed blocks rotatably sleeved on the fixed shaft are fixedly installed on the top of the windbreak plate. Both limiting blocks are fixedly sleeved on the outer wall of the fixed shaft. The two ends of the two torsion springs are respectively connected to one end of the limiting block and one end of the fixed block. The torsion springs form a reset structure to provide reset elasticity for the windbreak plate, ensuring that the windbreak plate can quickly reset after the pressure of the push plate is removed. At the same time, the symmetrically arranged torsion springs make the windbreak plate evenly stressed and the rotation process smooth and without jamming.

[0010] Preferably, the windbreak assembly further includes two protective plates fixedly installed at one end of the windbreak plate and used to protect the torsion spring. The protective plates cover the rotation gap between the torsion spring and the fixed block and the limiting block, which can prevent dust from entering the interior of the rotating pair, avoid corrosion and jamming of the torsion spring, and extend the service life of the reset structure.

[0011] Preferably, the adjustment component includes two push plates that move in opposite directions or in opposite directions. When the push plates move, they squeeze the outer walls of the two wind deflectors on the same side, causing the two wind deflectors on one side of the two wind deflector mechanisms to rotate in opposite directions. The two push plates correspond to the wind deflector mechanisms at the front and rear ends of the pipe body, respectively, so as to realize the reverse synchronous adjustment of the two wind deflector mechanisms, ensure the stability of the airflow field in the pipe, and avoid the problems of airflow turbulence and material settling.

[0012] Preferably, the adjusting assembly further includes a bidirectional screw for moving the two motors, a rotating shaft, a fixed base, a motor, a transmission shaft, a transmission gear, and a driven gear. The fixed base is fixedly installed on the outer wall of the pipe body. The rotating shaft and the bidirectional screw are both rotatably connected to the pipe body. The two push plates are respectively threaded onto the threaded sections on both sides. The transmission gear and the driven gear are respectively fixedly sleeved on the rotating shaft and the transmission shaft and mesh with each other. The motor is fixedly installed on the top of the fixed base, and its output end is fixedly connected to the transmission shaft. The adjusting mechanism also includes a protective cover that is detachably installed on the top of the fixed base, and the outer wall of the protective cover... The system has several heat dissipation holes. The multi-source sensing monitoring unit includes a pressure sensor, a powder concentration sensor, and a gas flow rate sensor, respectively located at the inlet and outlet sections of the pipeline body. The signal output terminals of the sensors are wirelessly connected to the closed-loop control unit of the motor to achieve adaptive adjustment. The motor is a forward and reverse servo motor, combined with gear transmission and bidirectional screw transmission, which can accurately control the moving distance of the push plate, thereby accurately adjusting the rotation angle of the baffle plate and realizing stepless adjustment of the pipeline flow area to adapt to different conveying conditions. The protective cover can protect the external transmission components from dust and rainwater corrosion, and the heat dissipation holes ensure the heat dissipation effect of the motor during operation to prevent overheating damage.

[0013] Preferably, the auxiliary components include a guide rod that slides with the push plate and rotates with the inner wall of the pipe body, and several elastic brushes one and two respectively sleeved on both ends of the guide rod. The elastic brushes one and two are both inverted conical in shape. The two auxiliary components are respectively located on both sides of the bidirectional screw. The guide rod provides guidance for the movement of the push plate, preventing the push plate from rotating with the bidirectional screw and ensuring smooth movement. The inverted conical elastic brushes one and two can drive the guide rod to rotate when the push plate moves along the guide rod, so that the elastic brushes can clean the dust on the thread groove of the bidirectional screw and the surface of the guide rod in real time, avoiding dust accumulation that causes thread jamming and sliding blockage, ensuring the operational stability of the transmission structure, and eliminating the need for manual cleaning and maintenance.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention utilizes a multi-source sensing monitoring unit and an adjustment component consisting of gears, screw transmission structures, and a windbreak mechanism. It uses pressure, concentration, and flow rate signals to drive a servo motor in a closed loop. The motor is decelerated by the meshing of transmission gears and driven gears, and synchronously driven by a bidirectional screw. This drives the push plate to precisely displace and push the windbreak plate to rotate, thus adaptively adjusting the pipeline flow area in real time. This enables proactive prediction and source suppression of pipe blockage precursors, replacing passive unblocking and reducing the probability of delivery interruption and pipeline mechanical damage.

[0015] 2. The bidirectional screw reverse thread synchronous transmission structure and the windproof assembly with torsion spring elastic reset of the present invention work together. By using the two sections of the bidirectional screw with opposite spiral directions, the two push plates are synchronously driven to move towards or away from each other, ensuring that the front and rear windproof mechanisms move in opposite directions synchronously, and the airflow field is stable and free of eddies. With the torsion spring elastic reset transmission, the windproof plate automatically and smoothly returns to its original position when there is no driving pressure, realizing stepless adjustment of the flow area and rapid reset, and taking into account both low resistance and energy saving and strong material carrying and anti-clogging effects.

[0016] 3. The windshield assembly protective plate sealing structure and auxiliary component guide rod linkage brush self-cleaning transmission, and external protective cover cooperate with each other. When the push plate slides along the guide rod, it drives the guide rod to rotate. The inverted conical elastic brush synchronously sweeps the bidirectional screw thread and the guide rod surface dust with the guide rod. The protective plate shields the torsion spring rotating pair, and the protective cover isolates external dust. The triple structure prevents dust from entering the transmission mating surface, avoids thread jamming and wear of the rotating pair, and ensures long-term stable operation of the transmission mechanism.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-7 As shown, an adaptive anti-clogging ash conveying pipeline includes a pipeline body 1, which is made of seamless steel pipe and has standard flanges at both ends for connection with other pipelines in the ash conveying system, making installation convenient. Inside the pipeline body 1, there are two wind-blocking mechanisms symmetrically distributed along the pipeline axis, namely a front wind-blocking mechanism and a rear wind-blocking mechanism. Each wind-blocking mechanism includes two wind-blocking components 2 symmetrically arranged on the left and right. The wind-blocking components 2 are equipped with a reset structure, which can adjust the flow area inside the pipeline body 1 by rotation, thereby adjusting the airflow range and velocity of the inlet or outlet air.

[0021] Specifically, the windbreak assembly 2 includes a windbreak plate 201, which is made of wear-resistant alloy steel and coated with a wear-resistant ceramic coating to enhance its wear resistance and suitability for conveying environments with high dust concentrations. One end of the windbreak plate 201 is provided with an arc-shaped groove 202, and both sides of the bottom are provided with arc-shaped side grooves 203. The windbreak plates 201 of the two windbreak assemblies 2 in the same windbreak mechanism can achieve end face contact by rotation. When contacting, the arc-shaped groove 202 and the arc-shaped side groove 203 fit together, which can limit the maximum rotation angle of the windbreak plate 201 to avoid excessive rotation, and also ensure the sealing of the contact point and accurately control the flow area.

[0022] The windbreak assembly 2 also includes a fixed shaft 205, a fixed block 206, a limiting block 207, and a torsion spring 208. The two ends of the fixed shaft 205 are rotatably connected to the inner wall of the pipe body 1 through bearings. The fixed shaft 205 is set horizontally along the radial direction of the pipe body 1. Two fixed blocks 206 are welded and fixed to the top of the windbreak plate 201. The fixed blocks 206 have rotating holes and are rotatably sleeved on the outer wall of the fixed shaft 205 through the rotating holes. Two limiting blocks 207 are also fixedly sleeved on the outer wall of the fixed shaft 205. The two limiting blocks 207 are located on the outside of the two fixed blocks 206 respectively. Two torsion springs 208 are provided, respectively sleeved on both ends of the fixed shaft 205 and located between the limiting blocks 207 and the fixed blocks 206. One end of the torsion spring 208 is welded and fixed to the limiting block 207, and the other end is welded and fixed to the fixed block 206, forming the reset structure of the windbreak plate 201.

[0023] Two protective plates 204 are welded and fixed to one end of the wind deflector 201 near the fixed shaft 205. The two protective plates 204 cover the outside of the two torsion springs 208 respectively. The protective plates 204 are arc-shaped plates and are coaxially set with the fixed shaft 205. They can completely block the rotation gap between the torsion spring 208 and the fixed block 206 and the limiting block 207, prevent dust from entering the interior of the rotating pair during the conveying process, avoid the torsion spring 208 from rusting or jamming, and ensure the long-term stable operation of the reset structure.

[0024] An adjustment mechanism 3 is provided on the outer wall of the main body of the pipe 1. The adjustment mechanism 3 includes an adjustment component 4 and two auxiliary components 5. The adjustment component 4 is used to drive the front windproof mechanism and the rear windproof mechanism to operate in opposite directions, so as to realize the synchronous adjustment of the two windproof mechanisms. The two auxiliary components 5 are symmetrically arranged on both sides of the adjustment component 4, and are used to guide and clean the transmission structure of the adjustment component 4 in real time.

[0025] Specifically, the adjustment component 4 includes a bidirectional screw 401, a rotating shaft 402, a fixed base 403, a motor 404, a transmission shaft 405, a transmission gear 406, a driven gear 407, and two push plates 400. The fixed base 403 is welded and fixed to the top outer wall of the pipe body 1. The motor 404 is fixedly installed on the top of the fixed base 403 by bolts. The motor 404 is a forward and reverse servo motor and is equipped with a servo controller. The servo controller is wirelessly connected to the sensors inside the pipe body 1. The output end of the motor 404 is fixedly connected to the transmission shaft 405 through a coupling. The driven gear 407 is keyed and fixedly sleeved on the end of the transmission shaft 405. The transmission gear 406 is keyed and fixedly sleeved on the end of the rotating shaft 402. The transmission gear 406 and the driven gear 407 mesh with each other to form a gear reduction transmission structure, which increases the transmission torque and ensures sufficient adjustment power.

[0026] The rotating shaft 402 is rotatably connected to the top wall of the pipe body 1 through a sealed bearing. The lower end of the rotating shaft 402 extends into the interior of the pipe body 1 and is coaxially welded and fixed with the bidirectional screw 401. The bidirectional screw 401 is arranged along the axial direction of the pipe body 1, and its two ends are rotatably connected to the inner wall of the pipe body 1 through bearings. The outer wall of the bidirectional screw 401 is provided with two threaded sections with opposite directions of rotation, namely the front threaded section and the rear threaded section. Two push plates 400 are respectively threaded onto the two reverse threaded sections. The lower end of the push plate 400 extends to the outer side of the two baffle plates 201 corresponding to the wind baffle mechanism. When the push plate 400 moves, it can squeeze the outer wall of the two baffle plates 201 on the same side, driving the two baffle plates 201 to rotate in opposite directions around the fixed shaft 205, thereby adjusting the flow area.

[0027] A protective cover 301 is detachably installed on the top of the fixed base 403 by bolts. The protective cover 301 completely covers the motor 404, the transmission gear 406 and the driven gear 407. Several heat dissipation holes are opened on the outer walls of both sides of the protective cover 301. Dust filters are installed in the heat dissipation holes, which can not only ensure the heat dissipation effect of the motor 404 during operation, but also prevent dust and rainwater from entering the interior of the protective cover 301 and protect the external transmission components.

[0028] The auxiliary component 5 includes a guide rod 501, an elastic brush 1 502, and an elastic brush 2 503. The guide rod 501 is arranged parallel to the bidirectional screw 401. The two ends of the guide rod 501 are rotatably connected to the inner wall of the pipe body 1 through bearings. The two push plates 400 are slidably sleeved on the outer wall of the guide rod 501 to guide the movement of the push plates 400 and prevent the push plates 400 from rotating with the bidirectional screw 401, thus ensuring the stability of the movement process. The elastic brush 1 502 and the elastic brush 2 503 are fixedly sleeved on the outer wall of the guide rod 501 and are located at the two ends of the bidirectional screw 401, respectively. The elastic brush 1 502 and the elastic brush 2 503 are both inverted conical structures, and their bristles are made of wear-resistant nylon material. The ends are in contact with the threaded groove of the bidirectional screw 401 and the outer wall of the guide rod 501.

[0029] When the push plate 400 moves along the guide rod 501, it can drive the guide rod 501 to rotate, thereby driving the elastic brush 1 502 and elastic brush 2 503 to rotate synchronously, cleaning the dust in the thread groove of the bidirectional screw 401 and the dust on the surface of the guide rod 501 in real time, avoiding dust accumulation that could cause thread jamming or slippage, and ensuring the operational stability of the transmission structure.

[0030] Sensors are fixedly installed inside the main body of the pipeline 1. The sensors include a pressure sensor, a flow rate sensor, and a differential pressure sensor, which are used to detect the air pressure, material conveying flow rate, and differential pressure data between the front and rear ends of the pipeline in real time. The sensors are wirelessly connected to the servo controller of the motor 404, which can transmit the detection data to the servo controller in real time. The servo controller automatically controls the forward and reverse rotation and the number of rotations of the motor 404 according to the preset threshold, so as to achieve adaptive adjustment.

[0031] Working principle: During normal transport, the material concentration inside the main body of the pipeline 1 is stable, and the airflow pressure and transport velocity are within the preset normal threshold range. The sensor transmits the detection data to the servo controller, which controls the motor 404 to remain stationary. At this time, the bidirectional screw 401 does not rotate, and the two push plates 400 are at both ends of the bidirectional screw 401, without squeezing the baffle plate 201. Under the elastic force of the torsion spring 208, the baffle plate 201 remains parallel to the inner wall of the main body of the pipeline 1. The flow area of ​​the main body of the pipeline 1 is maximized, the pipeline transport resistance is minimized, and the energy consumption of the transported air source is minimized, thus achieving energy-saving transport.

[0032] When the concentration of material in the pipeline increases and the gas source pressure fluctuates, the sensor detects that the pressure in the pipeline increases, the conveying flow rate decreases, and the pressure difference between the front and rear ends increases, reaching the preset pipe blockage warning threshold, the servo controller automatically starts the motor 404. The motor 404 drives the transmission shaft 405 to rotate, which drives the rotating shaft 402 to rotate through the meshing driven gear 407 and transmission gear 406, thereby driving the coaxial bidirectional screw 401 to rotate.

[0033] When the bidirectional screw 401 rotates, it drives the two push plates 400 to move towards each other along the guide rod 501 through two reverse threaded sections. During the movement of the push plates 400, they press the outer walls of the two baffle plates 201 of the corresponding side baffle mechanism, overcome the elastic force of the torsion spring 208, and drive the two baffle plates 201 to rotate in opposite directions around the fixed shaft 205. The ends of the two baffle plates 201 come close to each other and fit together, narrowing the flow area of ​​the main body of the pipe 1. At the same time, the front baffle mechanism and the rear baffle mechanism operate in opposite directions under the drive of the push plate 400 to ensure that the airflow field in the pipe is uniform and stable and no eddies are generated.

[0034] After the flow area is narrowed, the airflow velocity in the pipe increases instantaneously, enhancing the airflow's ability to carry materials. This lifts up materials that are about to settle and transports them forward, preventing material settling and accumulation from the source and preventing pipe blockage. The servo controller precisely controls the number of rotations of the motor 404 based on real-time detection data from the sensors, thereby precisely controlling the moving distance of the push plate 400 and the rotation angle of the baffle plate 201. This achieves stepless adjustment of the flow area until the pressure and flow velocity in the pipe return to the normal threshold range, realizing adaptive active anti-blocking.

[0035] During air intake and exhaust, the airflow drives the guide rod 501 to rotate, which in turn drives the elastic brush 1 502 and elastic brush 2 503 to rotate, cleaning the dust from the thread groove of the bidirectional screw 401 and the surface of the guide rod 501 in real time. This prevents dust from jamming the transmission structure and ensures the accuracy and reliability of the adjustment action. When the risk of blockage in the pipeline is eliminated and the sensors detect that parameters such as pressure and flow rate have returned to normal, the servo controller controls the motor 404 to rotate in the opposite direction, driving the bidirectional screw 401 to rotate in the opposite direction. This causes the two push plates 400 to move in opposite directions along the guide rod 501, removing the pressure on the baffle plate 201. Under the reset force of the torsion spring 208, the baffle plate 201 rotates in the opposite direction around the fixed shaft 205 to reset, becoming parallel to the inner wall of the pipeline body 1 again. The pipeline flow area returns to its maximum, returning to a low-resistance, energy-saving conveying state.
