Description

Technical Field

[0001] The present invention relates to the field of pipeline transportation, and particularly to a horizontal pipeline anti-settlement device, a disassembly and assembly method, and a material transportation system. Background Art

[0002] Pipeline transportation is a transportation method that uses pipelines as transportation tools to transport materials over a distance; taking the transportation of grain and pulverized coal as an example, the materials themselves are mainly composed of particles and contain impurity particles such as dust. When transporting them with the existing structure, the belt conveyor method is mostly used, that is, the driving motor drives the driving wheel to rotate, and the materials are transported to the corresponding position through the belt. Belt transportation requires manual management to avoid problems such as material particles spilling and the belt deflecting during transportation. Moreover, a large amount of dust will be generated during the belt transportation of granular materials, leading to occupational diseases of workers and environmental pollution. Pipeline transportation uses air as the conveying medium, forms a high-speed fluid in the conveying pipeline, and drives the material particles to be transported, which has the advantages of strong sealing, centralized dust treatment, and a very friendly working environment.

[0003] Since the particle sizes and densities of the transported material particles are different, when the high-speed fluid drives the material particles in the pipeline, a single air flow velocity will not be able to meet the actual use. That is, when the air flow velocity is small, the material particles will accumulate in the pipeline, causing pipeline blockage and seriously affecting the transportation. When the air flow velocity is large, the material particles will have a greater impact on the inside of the transportation pipeline, reducing its service life and causing waste of air power.

[0004] Chinese Patent Invention No. 201910321653.2: Limestone transportation system, its structure mainly seals and connects the pipelines through a connection motor and an automatic connection device, and a rotatable air supplement device is added at the connection to ensure that the particles do not deposit during transportation through air supplementation at different angles. Although the disclosed technical solution can achieve non-deposition during the particle transportation process, it requires timely air supplementation, which is equivalent to changing the air flow velocity by air supplementation at the positions where the particles are likely to accumulate, resulting in waste of air power. Summary of the Invention

[0005] The purpose of the present invention is to provide a horizontal pipeline anti-settlement device with a simple and compact structure, which does not require additional air supplementation and can effectively reduce the situation of material particles settling and blocking during transportation.

[0006] To achieve the above purpose, a horizontal pipeline anti-settlement device of the present invention includes an anti-settlement component located in a circular or rectangular anti-settlement pipeline.

[0007] The anti-settlement component includes a support seat detachably installed through an installation component and attached to the inner wall of the anti-settlement pipeline, and an anti-settlement block embedded at the upper end of the support seat.

[0008] The end face of the support seat facing the fluid conveying direction is arranged to incline upward along the fluid conveying direction;

[0009] Both side faces at the two ends of the anti-settling block are in contact with the inside of the anti-settling pipe, and the bottom side of the front end face facing the fluid conveying direction is smoothly transitioned with the corresponding end face of the support seat;

[0010] The front end face of the anti-settling block is a flat or arc-shaped structure, and the angle α between the flat or arc tangent and its bottom surface is 30-60°.

[0011] Further, when the front end face of the anti-settling block is an arc-shaped structure concave along the fluid conveying direction, the rear end face of the anti-settling block is an arc-shaped structure convex outward;

[0012] When the front end face of the anti-settling block is an arc-shaped structure convex along the fluid conveying direction, the rear end face of the anti-settling block is an arc-shaped structure concave inward;

[0013] When the front end face of the anti-settling block is a plane, the cross-section along the fluid conveying direction is triangular.

[0014] Further, the height of the anti-settling component is 0.1-0.5 times the diameter of the anti-settling pipe, and the distance to the fluid inlet of the anti-settling pipe is greater than 1.2 times the maximum settlement distance of the material particles conveyed by the fluid.

[0015] Further, the calculation formula for the maximum settlement distance L of the material particles conveyed by the fluid is:

[0016]

[0017] Among them: C D is the fluid resistance coefficient; g is the gravity coefficient; ρ is the air density; d is the particle diameter; ρ p is the density of the material particles; h is the diameter of the anti-settling pipe; v is the flow field velocity in the anti-settling pipe.

[0018] Further, the anti-settling component is installed on the upper wall or the lower wall of the anti-settling pipe;

[0019] When there are multiple groups of anti-settling components, they are arranged in a staggered manner up and down in sequence along the fluid conveying direction;

[0020] Each group of anti-settling components is fixed by 2-4 groups of installation components.

[0021] Further, a limiting block with a trapezoidal structure is provided at the lower end of the anti-settling block;

[0022] A limiting hole matching the limiting block is provided at the upper end of the support seat; the limiting hole is an open structure facing the fluid conveying direction;

[0023] The lower end face of the anti-settling block is in contact with the upper end face of the support seat.

[0024] Further, the installation component includes a locking bolt and a spring washer;

[0025] The support base is provided with a threaded hole, and the locking bolt passes through the through holes of the spring washer and the anti-settlement pipe and is threadedly installed on the support base;

[0026] Sealant is applied to the contact positions among the spring washer, the anti-settlement pipe, and the locking bolt.

[0027] The object of the present invention also lies in providing a disassembly and assembly method for a horizontal pipe anti-settlement device, which can quickly realize the disassembly and assembly of the anti-settlement component in the anti-settlement pipe and is applicable to anti-settlement pipes with different diameters;

[0028] A disassembly and assembly method for a horizontal pipe anti-settlement device specifically includes the following steps:

[0029] a. Threaded holes are correspondingly provided on one side of the support base and the anti-settlement block facing away from the fluid transportation direction;

[0030] The support end cover is disassembled and rotationally installed on the anti-settlement pipe. A hydraulic cylinder with axial telescopic movement is provided between the support disc body and the support end cover. The guide rod axially moves through the support end cover, one end is connected to the threaded holes on the support base and the anti-settlement block in a matching manner, and the other end is disassembled and installed on the support disc body;

[0031] b. When disassembling the anti-settlement block, the hydraulic cylinder is started, the support disc body axially moves and drives the guide rod, so that one end of the guide rod is butted against the threaded hole on the anti-settlement block. Then, the hydraulic cylinder drives the guide rod to move reversely along the fluid transportation direction, so that the limiting block at the lower end of the anti-settlement block is disengaged from the limiting hole on the support base. Then, the support end cover is rotated, and after the guide rod is displaced, it is taken out to complete the disassembly of the anti-settlement block;

[0032] When installing the anti-settlement block, the anti-settlement block is installed on the guide rod in advance. The guide rod is moved so that the anti-settlement block is located at the support base. The guide rod is moved along the fluid transportation direction, so that the limiting block at the lower end of the anti-settlement block is embedded into the limiting hole on the support base. The guide rod is rotated and taken out to complete the installation of the anti-settlement block;

[0033] c. When disassembling the anti-settlement component, the radial position of the guide rod is adjusted so that one end of the guide rod is butted against the threaded hole on the support base. After the guide rod is connected to the threaded hole on the support base, the locking bolt for fixing the support base is disassembled, and the hydraulic cylinder is started to drive the guide rod to move, and the anti-settlement component is taken out;

[0034] Similarly, when installing the anti-settlement component, the anti-settlement block and the support base are assembled in advance, and then the guide rod is threadedly fixed to the support base. The guide rod is moved to the installation position, and after the locking bolt and the spring washer are coated with sealant, they pass through the anti-settlement pipe to fix the support base, and then the guide rod is rotated and taken out to complete the installation of the anti-settlement component.

[0035] The object of the present invention is also to provide a material conveying system, which can effectively reduce the sedimentation and blockage of material particles during the conveying process without changing the conveying flow rate.

[0036] A material conveying system includes the horizontal pipeline anti-sedimentation device, a driving component for generating pressured air flow, and a conveying pipeline connected to the driving component;

[0037] A feeder is provided on the conveying pipeline, and the other end is communicated with an anti-sedimentation pipeline;

[0038] When the anti-sedimentation pipeline is of a rectangular structure, a converter is provided between the conveying pipeline and the anti-sedimentation pipeline.

[0039] Further, a pressure gauge for detecting the fluid pressure is provided on the conveying pipeline;

[0040] The driving component includes an air compressor and a gas storage tank connected to the air compressor, and the output end of the gas storage tank is connected to the conveying pipeline.

[0041] Compared with the prior art, in this horizontal pipeline anti-sedimentation device, since an anti-sedimentation component is provided in the anti-sedimentation pipeline, the front end face of the anti-sedimentation block is a plane or an arc structure, and the angle α between the plane or the arc tangent and its bottom surface is 30-60°. That is, the material particles pass through the anti-sedimentation blocks in the shape of a triangle or a wave or a fin with an angle of 30-60°. Not only is the transition smooth, which can accelerate the flow of material particles, but also the structure is simple and compact, without the need for additional air supplementation, effectively reducing the sedimentation and blockage of material particles during the conveying process;

[0042] When the anti-sedimentation component is installed on the upper wall of the anti-sedimentation pipeline, the flow field presses down at this time, accelerating the sedimented particles at the bottom and pushing the particles to move, which is suitable for material particles with larger particle sizes and densities; when the anti-sedimentation component is installed on the lower wall of the anti-sedimentation pipeline, the flow field rises, accelerating the upper particles and pushing the particles to move, which is suitable for material particles with smaller particle sizes and densities; in addition, multiple groups of anti-sedimentation components are arranged staggered up and down, so that the passing flow fields are coupled, and the particles are correspondingly accelerated in a staggered manner, reducing the kinetic energy loss of the material particle conveying, improving the conveying efficiency and the service life of the anti-sedimentation pipeline, and effectively preventing pipeline conveying blockage. Therefore, different installation methods of the anti-sedimentation components in the anti-sedimentation pipeline can play different functions, which is more precise;

[0043] Compared with the prior art, the disassembly and assembly method of this horizontal pipeline anti-sedimentation device can quickly realize the disassembly and assembly of the anti-sedimentation component in the anti-sedimentation pipeline and is applicable to anti-sedimentation pipelines with different diameters; this material conveying system only needs to add an anti-sedimentation component in the anti-sedimentation pipeline, which can effectively reduce the sedimentation and blockage of material particles during the conveying process without changing the conveying flow rate.

[0060] The present invention will be further described below with reference to the accompanying drawings.

[0061] As Figures 1 to 4 shown, a horizontal pipeline anti-settlement device of the present invention includes an anti-settlement component 2 located in a circular or rectangular anti-settlement pipeline 1;

[0062] The anti-settlement component 2 includes a support seat 21 detachably installed through an installation component 3 and attached to the inner wall of the anti-settlement pipeline 1, and an anti-settlement block 22 embedded at the upper end of the support seat 21;

[0063] The end face of the support seat 21 facing the fluid conveying direction is arranged obliquely upward along the fluid conveying direction;

[0064] Both side faces 222 at both ends of the anti-settlement block 22 are attached to the inside of the anti-settlement pipeline 1, and the bottom side of the front end face 221 facing the fluid conveying direction is smoothly transitioned with the corresponding end face of the support seat 21;

[0065] The front end face 221 of the anti-settlement block 22 is a flat or arc-shaped structure, and the angle α between the flat or arc-shaped tangent and its bottom surface is 30-60°.

[0066] Specifically, the anti-settlement pipeline 1 is generally horizontally arranged. The support seat 21 can be made of high-strength steel, and the anti-settlement block 23 can be made of hard alloy steel and replaced and installed on the support seat 21. Different structures are selected according to actual situations; in the anti-settlement pipeline 1, mainly through logistics particles and high-pressure gas, a fluid is formed during circulation;

[0067] One end face of the support seat 21 is inclined upward along the fluid conveying direction and is smoothly transitioned with the anti-settlement block 22. This structure mainly enables the fluid to smoothly pass through the anti-settlement component 2 and avoids the impact of the fluid on the anti-settlement component 2;

[0068] The anti-settlement component 2 is attached to the inner wall of the anti-settlement pipeline 1. That is, when the anti-settlement pipeline 1 is a rectangular structure, the support seat 21 is a rectangular block, and the side faces 222 of the anti-settlement block 22 are flat and attached to the inner wall of the anti-settlement pipeline 1; when the anti-settlement pipeline 1 is a circular structure, the contact surface between the support seat 21 and the anti-settlement pipeline 1 is an arc structure, and the side faces 222 of the anti-settlement block 22 are also arc structures, avoiding the fluid directly passing through the inside of the anti-settlement component 2 and the settlement of particles in the anti-settlement component 2.

[0069] As Figures 7 to 8As shown, exemplary, when the front end face 221 of the anti-settling block 22 is an arc-shaped structure that is concave inward along the fluid transport direction, the rear end face 225 of the anti-settling block 22 is an arc-shaped structure that is convex outward, which can be a wave-shaped structure. For example, the anti-settling block 22 is a 30°, 45°, or 60° wave-shaped structure and is located in a circular or rectangular anti-settling pipe 1;

[0070] When the front end face 221 of the anti-settling block 22 is an arc-shaped structure that is convex outward along the fluid transport direction, the rear end face 225 of the anti-settling block 22 is an arc-shaped structure that is concave inward, which can be a fin-shaped structure. For example, the anti-settling block 22 is a 30°, 45°, or 60° fin-shaped structure and is located in a circular or rectangular anti-settling pipe 1;

[0071] When the front end face 221 of the anti-settling block 22 is a plane, the cross-section along the fluid transport direction is triangular, that is, the anti-settling block 22 is a 30°, 45°, or 60° triangular structure and is located in a circular or rectangular anti-settling pipe 1.

[0072] Furthermore, the height of the anti-settling component 2 is 0.1 - 0.5 times the diameter of the anti-settling pipe 1, and the distance from the anti-settling component 2 to the fluid inlet of the anti-settling pipe 1 is greater than 1.2 times the maximum settlement distance of the material particles transported with the fluid;

[0073] The calculation formula for the maximum settlement distance L of the material particles transported with the fluid is:

[0074]

[0075] Where: C D is the fluid resistance coefficient; g is the gravity coefficient; ρ is the air density; d is the particle diameter; ρ p is the density of the material particles; h is the diameter of the anti-settling pipe 1; v is the flow field velocity inside the anti-settling pipe 1.

[0076] Furthermore, the anti-settling component 2 is installed on the upper wall or the lower wall of the anti-settling pipe 1. When there are multiple groups of anti-settling components 2, they are arranged in a staggered manner up and down in sequence along the fluid transport direction;

[0077] Each group of anti-settling components 2 is fixed by 2 - 4 groups of installation components 3.

[0078] Specifically, different installation methods of the anti-sinking components 2 in the anti-sinking pipe 1 can play different functions. According to the particle size and density of the conveyed material particles, a suitable anti-sinking pipe 1 is selected, and multiple groups of anti-sinking components 2 with a slope of α° are arranged in the anti-sinking pipe 1. That is, when the particle size, density and weight of the material particles are large, the material particles are deposited at the bottom of the pipe. The anti-sinking component 2 can be set on the upper wall of the anti-sinking pipe 1. At this time, the flow field presses downward, accelerates the particles deposited at the bottom, promotes the movement of the particles, and makes the particles settled at the bottom of the anti-sinking pipe 1 return to the conveying flow field; when the particle size, density and weight of the material particles are small, the particles are suspended in the upper part of the pipe. The anti-sinking component 2 can be set on the lower wall of the anti-sinking pipe 1. At this time, the flow field rises, accelerates the upper particles, promotes the movement of the particles, and makes the particles suspended in the upper part of the anti-sinking pipe 1 return to the conveying flow field;

[0079] If two sets of anti-sinking components 2 are installed on the upper and lower walls of the anti-sinking pipe 1, flow field coupling will be formed, and the particle staggering will be accelerated accordingly, so as to improve the transportation efficiency and the service life of the anti-sinking pipe 1, and effectively prevent pipeline transportation blockage.

[0080] This horizontal pipeline anti-sinking device is tested with an anti-sinking block 22 having a 45° fin-shaped structure located in a rectangular anti-sinking pipeline 1;

[0081] Example 1

[0082] 3kg of conveying material is fed into the anti-settling test pipe through the material suction device. Material particles (such as coal particles) enter four different transparent anti-settling pipes 1 through the connecting flange 61 for conveying tests.

[0083] Place the conveyed material into the test pipe without the anti-settling component 2, observe the conveying and settling of the conveyed material, verify the calculated maximum settling distance L of the particles by pneumatic conveying, and record the total conveying time t1 of 3 kg of conveyed material, as well as the conveying and settling of the material;

[0084] After the transportation is completed, the masses of the conveyed materials are 1644.0g, 1673.5g, 1684.6g, 1677.3g, 1663.2g and 1667.3g respectively, and the remaining materials are in the feeder 4. The time taken to complete the transportation is 9.0s, 8.0s, 8.0s, 9.0s, 8.0s and 9.0s respectively, and the obtained conveying speeds are 150.1g / s, 163.4g / s, 162.1g / s, 144.6g / s, 164.5g / s and 145.8g / s respectively. During the transportation process, the coal particles are separated from the flow field as the transportation distance increases, and the accumulation phenomenon becomes more and more obvious. The coal particles will accumulate in the conveying pipe 7, which not only reduces the transportation efficiency of the particles, but also causes more serious wear of the pipe.

[0085] Example 2

[0086] Install the anti - sedimentation component 2 on the upper wall of the rectangular anti - sedimentation pipeline 1, convey the material into the anti - sedimentation pipeline 1, observe the conveying situation of the conveyed material under the action of the downward pressure flow field, and record the total conveying time t2 of 3 kg of conveyed material and the secondary sedimentation distance L of the particles ’ 2. After the conveying is completed, the masses of the six portions of coal particles are 1880.6 g, 1783.7 g, 1865.6 g, 1920.7 g, 1957.4 g, and 1768.4 g respectively, and the remaining material is in the feeder 4. The times taken for the conveying to complete are 6.0 s, 7.0 s, 6.0 s, 6.0 s, 6.0 s, and 7.0 s respectively, and the obtained conveying speeds are 186.6 g / s, 173.0 g / s, 187.9 g / s, 178.6 g / s, 172.3 g / s, and 174.4 g / s respectively. During the transportation process, the coal particles and the gas move downward from the original flow field, causing the flow field for transporting the coal particles to change sharply during this period, and the speed of the conveying gas also increases, and the speed of the coal particles in the square pipe becomes faster. Due to the change in the flow field during the transportation of the coal particles, some particles collide with the anti - sedimentation device, but the overall conveying speed of the particles is still faster, and to a certain extent, the problem of coal particle sedimentation in the horizontal square pipe is also solved;

[0087] Example 3

[0088] Install the anti - sedimentation component 2 on the lower wall of the rectangular anti - sedimentation pipeline 1, convey the material into the anti - sedimentation pipeline 1, observe the conveying situation of the conveyed material under the action of the upward flow field, and record the total conveying time t3 of 3 kg of conveyed material and the secondary sedimentation distance L of the particles ’ 3; After the conveying is completed, the masses of the six portions of coal particles are 1821.3 g, 1775.4 g, 1843.3 g, 1819.5 g, 1842.0 g, and 1783.1 g respectively, and the remaining material is in the feeder 4. The times taken for the conveying to complete are 6.0 s, 6.0 s, 6.0 s, 6.0 s, 6.0 s, and 6.0 s respectively, and the obtained conveying speeds are 196.5 g / s, 203.8 g / s, 192.4 g / s, 196.2 g / s, 191.7 g / s, and 201.2 g / s respectively. During the transportation process, the particles return to the flow field again, and the problem of coal particle sedimentation in the horizontal square pipe is solved;

[0089] Example 4

[0090] Install 2 groups of anti - sedimentation components 2 on the rectangular anti - sedimentation pipeline 1, convey the material into the anti - sedimentation pipeline 1, and observe the conveying situation of the conveyed material under the action of the coupled flow field

[0091] And record the total conveying time t4 of 3 kg of conveyed material and the secondary sedimentation distance L of the particles’ 4. After the conveying is completed, the masses of the six portions of coal particles are 1828.1 g, 1800.5 g, 1850.7 g, 1907.4 g, 1808.1 g, and 1846.3 g respectively, and the remaining materials are in the feeder 4. The times taken for the conveying to complete are 6.0 s, 6.0 s, 6.0 s, 5.0 s, 6.0 s, and 6.0 s respectively, and the obtained conveying speeds are 195.3 g / s, 199.8 g / s, 191.3 g / s, 218.1 g / s, 197.8 g / s, and 191.0 g / s respectively. During the transportation process, the coal particles first pass through the anti-settling component 2 on the upper wall, and the speed of the particles increases sharply under the action of the anti-settling component 2; then they pass through the anti-settling component 2 on the lower wall, and the particles show a phenomenon of rising and return to the flow field again, solving the problem of coal particle settlement in the horizontal square pipe.

[0093] A limiting hole matching the limiting block 224 is provided at the upper end of the support seat 21; the limiting hole is an open structure facing the fluid conveying direction;

[0094] Specifically, when installing the anti-settling block 22, it can be directly inserted into the limiting hole along the fluid conveying direction through the limiting block 224 to achieve its installation and fixation. It should be noted that the lower end surface of the anti-settling block 22 is in contact with the upper end surface of the support seat 21;

[0095] Further, the installation component 3 includes a locking bolt 31 and a spring washer 32;

[0097] As another embodiment, a through hole is provided on the support seat 21, and an installation hole 223 is provided at the bottom of the limiting block 224, that is, the locking bolt 31 passes through the spring washer 32, the through hole of the anti-settling pipe 1, and the support seat 21 and is then threadedly installed on the installation hole 223 on the limiting block 224;

[0098] Sealing glue is applied to the contact positions between the spring washer 32, the anti-settling pipe 1, and the locking bolt 31;

[0099] Specifically, a threaded hole is provided on the limiting block 224 along the radial direction of the anti-settling pipe 1, and a corresponding through hole is provided on the support seat 21, that is, when the limiting block 224 is inserted into the limiting hole on the support seat 21, the through hole on the support seat 21 corresponds to the threaded hole on the limiting block 224;

[0100] The rod of the locking bolt 31 passes through the anti-sinking pipe 1 and the support base 21 and is threadedly installed on the limit block 224 to achieve fixation between the support base 21 and the anti-sinking pipe 1, and between the anti-sinking block 22 and the support base 21;

[0101] In addition, sealant may be applied to the locking bolts 31 and the through holes of the anti-sinking pipe 1 to effectively prevent fluid leakage.

[0103] A hydraulic cylinder 92 for axial telescopic movement is provided between the support end cover 91 and the support plate body 93;

[0106] The specific disassembly and assembly steps include: first, selecting the matching support end cap 91 and support disc 93 according to the inner diameter of the anti-sinking pipe 1;

[0107] The support end cover 91 is coaxially disassembled and installed with the anti-sinking pipe 1, and the support disc 93 may be provided with a strip hole corresponding to the radial position of the anti-sinking block 22 and the support seat 21;

[0108] The guide rod 94 passes through the strip-shaped hole on the support plate 93 and is locked and fixed by nuts on both sides of the support plate 93 and screwed on the guide rod 94;

[0109] When the anti-sinking block 22 is disassembled, the hydraulic cylinder 92 is started, the support disc 93 moves axially and drives the guide rod 94 so that one end of the guide rod 94 is docked with the second threaded hole 226 on the anti-sinking block 22, and the nut fixed at the other end of the guide rod 94 is loosened to enable it to rotate. After the end of the guide rod 94 is threadedly installed in the second threaded hole 226, the nut is tightened and fixed. The hydraulic cylinder 92 is started to drive the guide rod 94 to move in the opposite direction of fluid delivery, so that the limit block 224 at the lower end of the anti-sinking block 22 is separated from the support seat 21. , and then rotate the support end cover 91 so that the guide rod 94 is staggered, remove the nut on the guide rod 94 and take it out to complete the removal of the anti-sinking block 22. Similarly, when installing the anti-sinking block 22, install the anti-sinking block 22 on the guide rod 94 in advance so that the anti-sinking block 22 is located at the support seat 21. Move the guide rod 94 along the fluid conveying direction so that the limit block 224 at the lower end of the anti-sinking block 22 is embedded in the limit hole on the support seat 21. Rotate the guide rod 94 to take it out to complete the installation of the anti-sinking block 22.

[0110] When disassembling the anti-sinking assembly 2, that is, disassembling the anti-sinking block 22 and the entire structure of the support seat 21, the radial position of the guide rod 94 is adjusted. For example, different through holes or radially arranged strip holes are provided on the support disc 93 so that one end of the guide rod 94 is docked with the first threaded hole 221 on the support seat 21. Preferably, the first threaded hole 221 and the second threaded hole 226 can be threaded holes of the same diameter, or there are multiple guide rods 94, the difference being that one end matches the first threaded hole 221 and the second threaded hole 226 respectively.

[0111] After the guide rod 94 is connected to the first threaded hole 221 on the support seat 21, the locking bolt 31 used to fix the support seat 21 is removed, and the hydraulic cylinder 92 is started to drive the guide rod 94 to move, and the anti-sinking component 2 is taken out; similarly, when installing the anti-sinking component 2, the anti-sinking block 22 and the support seat 21 are assembled in advance, and then the guide rod 94 is threadedly fixed to the support seat 21, and the guide rod 94 is moved to the installation position. After applying sealant, the locking bolt 31 and the spring washer 32 are passed through the anti-sinking pipe 1 to fix the support seat 21, and then the guide rod 94 is rotated to take it out, and the installation of the anti-sinking component 2 is completed;

[0112] It should be noted that although the anti-sinking block 22 and the support seat 21 are embedded with the limit block 224 and the limit hole, there is still damping friction between them during actual use to prevent the anti-sinking block 22 from automatically detaching from the support seat 21 when the support seat 21 is moved. This method for disassembling and assembling a horizontal pipeline anti-sinking device can quickly realize the disassembly and assembly of the anti-sinking component in the anti-sinking pipeline and is applicable to anti-sinking pipelines of different diameters.

[0113] like Figure 12 As shown, a material conveying system includes the horizontal pipeline anti-settling device, a driving component for generating a pressurized airflow, and a conveying pipeline 7 connected to the driving component;

[0114] A feeder 4 is provided on the conveying pipeline 7, and the other end is connected to the anti-settling pipeline 1;

[0115] When the anti-settling pipeline 1 is of a rectangular structure, a converter 62 is provided between the conveying pipeline 7 and the anti-settling pipeline 1;

[0116] Furthermore, a pressure gauge 5 for detecting the fluid pressure is provided on the conveying pipeline 7;

[0117] Specifically, the driving assembly includes an air compressor 81 and an air storage tank 82 connected to the air compressor 81, and the output end of the air storage tank 82 is connected to the conveying pipeline 7;

[0118] The conveying pipeline 7 for material conveying is generally of a circular structure. When the anti-settling pipeline 1 is also of a circular structure, the connecting flange 61 on the end side of the conveying pipeline 7 can be directly docked with the anti-settling pipeline 1. When the anti-settling pipeline 1 is of a rectangular structure, the connecting flange 61 on the end side of the conveying pipeline 7 is docked with the anti-settling pipeline 1 through the converter 62;

[0119] Start the driving assembly, convey the pressurized fluid (air flow) into the conveying pipeline 7, drive the material introduced from the feeder 4 for conveying, the material is conveyed to the anti-settling pipeline 1, passes through the anti-settling assembly 2 on its inner wall, and through the anti-settling blocks 22 in a triangular or wave-shaped or fin-shaped structure at 30° - 60°, effectively preventing the material particles from settling in the anti-settling pipeline 1.
