Description

Technical Field

[0001] The invention relates to the technical field of electromagnetic pipe vibrators, in particular to a diameter-adjustable feedback electromagnetic pipe vibrator. Background Art

[0002] Coal is my country's primary energy source. However, coal mining also produces large quantities of gangue. Because the amount of gangue utilized is less than the amount generated, new stockpiles are added annually. By 2024, my country's gangue production will reach 825 million tons, a year-on-year increase of 2.1%, and the cumulative stockpile will exceed 7 billion tons.

[0003] Mine mining and filling primarily involves coal mining, sorting raw coal from gangue, and then crushing, drying, and backfilling the sorted gangue. Gangue backfilling involves directly transporting and crushing the gangue generated during tunneling, then transporting it to the tunneling face via feeders and belt conveyors. However, with the increasing mechanization of mining, the amount of gangue is increasing. Complex and inefficient transportation, resulting in environmental pollution and high handling costs, have severely constrained mine development. Pneumatic conveying is a modern method that uses the flow energy of air (or other gases) to move powdered, granular, or small lumps from one location to another through pipelines. It is particularly suitable for transporting large quantities of material over long distances and along complex routes. Therefore, pneumatic conveying is a preferred method for gangue backfilling.

[0004] At present, pneumatic conveying is widely used in chemical, food, pharmaceutical, metallurgy, building materials and other industries due to its advantages of strong environmental protection, low pollution, flexible conveying, high efficiency and space saving. However, for long-distance pneumatic conveying underground, the following problems often exist due to the nature of the conveyed materials and the complexity of the working conditions: 1. Pipe blockage during conveying: Low-speed, dense-phase pneumatic conveying is commonly used in long-distance pneumatic conveying systems. This method offers high conveying efficiency, minimal wear, and low material breakage. However, due to the low speed, the material's contact area with the pipe wall is large, increasing friction between the material and the pipe wall. The material then settles downward due to frictional resistance. Consequently, pipe blockage is common, reducing conveying efficiency.

[0005] 2. Dust adhesion problem on pipe wall: During the pneumatic conveying process, due to the physical properties of the conveyed material (excessive proportion of fine powder, strong hygroscopicity, rough surface) and chemical properties (electrostatic effect), dust will adhere to the inner wall of the conveying pipe, reducing the effective conveying cross-sectional area of ​​the pipe, increasing the conveying resistance, and causing material deposition and blockage.

[0006] 3. The conveying pressure in the existing pipeline will change with the situation of the conveyed material, and the existing pipe vibrator cannot selectively vibrate according to the blockage situation in the pipeline. Long-term vibration will affect the strength and structure of the pipeline and cause energy waste.

[0007] 4. Existing pipe vibrators are difficult to adapt to pipes of different diameters and have poor applicability. Summary of the Invention

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figures 1 to 14 As shown, the present invention includes the following embodiments: Example 1: A diameter-adjustable feedback electromagnetic vibrator, comprising a vibrator 1 and a mounting assembly; the vibrator 1 comprises a vibration shell 11, a coil base 12, a metal plate 14, a first slider 15, a copper coil 16, and a vibration spring 17; the two coil bases 12 are located on both sides of the metal plate 14, and a copper wire groove 121 and a first slide 122 are provided on one side close to each other; the copper wire groove 121 is embedded in the copper coil 16; the first slide 15 is slidably connected in the first slide 122; the first slide 15 is fixedly connected to the metal plate 14; the coil base 12 is made of laminated silicon steel sheets; the metal plate Block 14 is an aluminum block used to cut magnetic lines of force, with vibration springs 17 installed at both ends; the other end of the vibration spring 17 rests on the inner wall of the vibration shell 11; the vibration shell 11 is composed of an upper shell 111 and a lower shell 112 that cover each other; the coil base 12, the metal plate 14, and the vibration spring 17 are located inside the vibration shell 11; the vibration shell 11 is placed on the inside of the mounting assembly; a sensor 2 connected to the inside of the pipeline is provided on the outer wall of the pipeline; the sensor 2 is used to monitor the pressure signal in the pipeline in real time, forming a closed-loop feedback control with the vibrator 1, and automatically adjusting the current input to the copper coil 16 according to the pressure signal to control the vibration frequency.

[0025] First, use the mounting assembly to mount the vibrator 1 on the outer wall of the pipeline, and then mount the sensor 2 on the outer wall of the pipeline in the conveying direction. Turn on the power and start the pipeline conveying. Since the present invention is based on the principle of electromagnetic induction, after the copper coil 16 is supplied with alternating current, a traveling wave magnetic field with linear motion will be generated. The traveling wave magnetic field cuts the metal plate and generates induced eddy currents. The eddy currents interact with the traveling wave magnetic field to generate electromagnetic force, which pushes the metal plate 14 to move linearly. When the direction of the current is changed, the direction of movement will also be changed. The present invention designs two upper and lower coil bases 12. When the copper coil 16 in the upper coil base 12 is energized, the metal plate 14 moves in the horizontal direction. When the copper coil 16 in the lower coil base 12 is energized, the metal plate 14 can move in the opposite direction. By alternately energizing the upper and lower copper coils 16, the reciprocating motion of the metal plate 14 can be achieved. In addition, since vibration springs 17 are installed at both ends of the metal plate 14, the vibration springs 17 will store energy when compressed, and will generate lateral vibration when released. , thereby achieving the effect of vibrating the pipe; and due to the effect of inertia, the particles that are blocked in the pipe or the particles that have a tendency to clog can be vibrated and dispersed, thereby achieving the effect of unclogging the pipe and improving the transportation efficiency; due to the different properties of the particles, some of the transported particles will adhere to the wall of the conveying pipe due to hygroscopicity, adhesion or under the action of static electricity, on the one hand, it will reduce the effective conveying cross-sectional area of ​​the pipe, and on the other hand, it will increase the resistance during transportation; to this end, the present invention can adopt a method of vibrating the pipe to make the dust particles adhering to the pipe wall fall off and be output from the pipe together with the airflow, thereby reducing dust adhesion and effectively improving the stability of transportation; the present invention realizes closed-loop feedback control by cooperating with the sensor 2, and automatically adjusts the magnitude of the current input to the copper coil 16 through the change of the pressure signal output by the sensor 2 in real time, thereby controlling the frequency of the linear motion of the metal plate 14, and then vibrating the pipe when it is needed to dredge the pipe, on the one hand reducing energy loss, and on the other hand avoiding damage to the pipe caused by long-term vibration of the pipe, that is, vibrating the pipe will only be performed when needed.

[0026] Example 2: The mounting assembly includes an arc-shaped slide 3 and a fixed plate 31; one end of the two fixed plates 31 is fixedly connected to a mounting ear 32; the mounting ear 32 passes through and is connected to a mounting bolt 33; the other ends of the two fixed plates 31 are provided with a second slide groove 34; the slide 3 is slidably connected in the second slide groove 34; the two slides 3 are hinged to each other at one end away from the fixed plate 31; a rubber plate 35 is adhered to the inner wall of the fixed plate 31; and the vibrator 1 is embedded in the rubber plate 35.

[0027] The slide plate 3 can slide along the second slide groove 34 at the other end of the fixed plate 31. The two slide plates 3 are hinged to each other at one end away from the fixed plate 31. After the mounting bolts 33 are tightened, they can be adjusted within a certain circumferential range to adapt to pipes of different specifications and sizes, thereby improving installation flexibility; the minimum adjustment diameter is 120 mm and the maximum diameter is 200 mm.

[0028] Example 3: The mounting assembly includes a plurality of arc plates 4; a single arc plate 4 is circumferentially connected to two extension plates 5; the vibrator 1 is embedded in the inner surface of the arc plate 4 and is covered with a rubber pad 18; one of the extension plates 5 on the single arc plate 4 is fixedly connected to the first connecting rod 6 at a front position away from one end of the arc plate 4; the first connecting rod 6 is provided with a socket 61 at the rear end; the other extension plate 5 on the single arc plate 4 is fixedly connected to the second connecting rod 7 at a rear position away from one end of the arc plate 4; the second connecting rod 7 is provided with a movable hole 71 at the front end; the movable hole 71 is movably connected to the insertion rod 8; the insertion rod 8 is connected to the bottom of the movable hole 71 through a first spring 81; the arc-shaped inner wall of the movable hole 71 is provided with a shift groove 72 facing outward; the shift groove 72 is slidably connected to the shift block 73; the shift block 73 is fixed to the arc-shaped outer wall of the insertion rod 8.

[0029] Before installing the pipe vibrator on the curved outer wall of the pipeline, first confirm the outer diameter of the pipeline and select the corresponding number of curved plates 4 according to the outer diameter. After determining the number of curved plates 4, the adjacent curved plates 4 are spliced ​​while reserving an interface. The first connecting rod 6 on one curved plate 4 is docked with the second connecting rod 7 on the other curved plate 4. After the socket 61 of the first connecting rod 6 is aligned with the movable hole 71 of the second connecting rod 7, the protruding plug 8 on the second connecting rod 7 is controlled to be inserted into the socket 61 on the corresponding first connecting rod 6 to achieve The connection of adjacent curved plates 4, after completing the connection of multiple curved plates 4 and reserving an interface, the multiple curved plates 4 formed into a strip are enclosed on the curved outer wall of the pipe that needs to be vibrated, and then the last two curved plates 4 are controlled to approach each other, and the first connecting rod 6 and the second connecting rod 7 on the last two curved plates 4 are approached to each other, and the shift block 73 on the second connecting rod 7 to be connected is shifted. After being shifted, the shift block 73 will slide along the shift groove 72. Since the length direction of the shift groove 72 is consistent with the axial direction of the second connecting rod 7, when the shift block 73 is shifted, the shift block 73 will slide along the shift groove 72. After the movement, the rod 8 will be driven to slide along the movable hole 71. After the rod 8 is moved, it will overcome the elastic force of the first spring 81 and retract into the movable hole 71. In this way, the first connecting rod 6 and the second connecting rod 7 on the last two arc plates 4 can be aligned smoothly. After the dial block 73 is released, the first spring 81 will push the rod 8 to be inserted into the aligned insertion hole 61, thereby realizing the connection of the last two arc plates 4. The multiple arc plates 4 are enclosed to form a complete ring, realizing the covering of the pipeline, completing the installation process of the pipe vibrator, and the vibrator 1 on the inner side of the arc plate 4 is realized when it is started. Vibration of the pipeline; and when it is necessary to remove the installation component from the outer wall of the pipeline, it is only necessary to move one of the shift blocks 73 to drive the insert rod 8 to retract into the movable hole 71, so that one of the first connecting rods 6 and the second connecting rod 7 can be disconnected, thereby disconnecting the two adjacent arc plates 4; this embodiment can select a corresponding number of arc plates 4 for connection according to the outer diameter of the pipeline, so that the pipe vibrator can be suitable for installation of more diameters, expanding the scope of application of the pipe vibrator; the rubber pad 18 in this embodiment serves the purpose of anti-slip.

[0030] Example 4: The insert rod 8 is provided with a guide angle 82 at one end away from the first spring 81; the arc-shaped outer wall of the insert rod 8 is provided with an annular card groove 83; the arc-shaped inner wall of the insertion hole 61 is provided with a groove 62 aligned with the card groove 83; the card block 63 is slidably connected in the groove 62; the card block 63 is connected to the bottom of the groove 62 through a second spring 64; the bottom of the groove 62 is provided with a pull groove 65 facing outward; the pull groove 65 is slidably connected to an L-shaped pull block 66; the pull block 66 is fixedly connected to the card block 63.

[0031] When the plug rod 8 is inserted into the socket 61, the guide angle 82 of the plug rod 8 away from the first spring 81 will squeeze the block 63, so that the block 63 is under pressure to overcome the first spring 81 and retract into the groove 62 for avoidance. When the block 63 approaches the bottom of the groove 62, it will drive the pulling block 66 to move outward along the pulling groove 65. After the groove 62 and the slot 83 are aligned, the block 63 extends from the groove 62 into the slot 83 under the action of the second spring 64. After the block 63 is stuck in the slot 83, the axial locking of the plug rod 8 and the socket 61 is achieved, so that the plug rod 8 cannot be separated from the socket 61, thereby improving the connection stability of the first connecting rod 6 and the second connecting rod 7. ; Since the slot 83 is annular, the block 63 can move circumferentially along the slot 83, so that the rod 8 can rotate in the socket 61, without affecting the rotation of the first connecting rod 6 and the second connecting rod 7, thereby satisfying the adjustment of the angle between adjacent arc plates 4, and better adapting to the outer wall of the pipeline; when it is necessary to pull the rod 8 out of the socket 61, it is necessary to pull the pull block 66 to slide along the pull groove 65, and the pull block 66 will drive the block 63 to overcome the second spring 64 and retract into the groove 62, and the block 63 will move out of the slot 83, realizing axial unlocking of the rod 8 and the socket 61, so that the rod 8 can be driven to move out of the socket 61.

[0032] Example 5: The outer wall of the arc-shaped plate 4 in the circumferential direction is provided with an extension groove 41 ; the extension plate 5 is slidably connected in the extension groove 41 ; the extension plate 5 is connected to the bottom of the extension groove 41 via a tension spring 42 .

[0033] After the plurality of curved plates 4 are connected into a strip and an interface is reserved, the plurality of curved plates 4 in the strip are enclosed on the outer wall of the pipe, and then the plurality of curved plates 4 in the strip are pulled, so that the extension plate 5 will slide with the corresponding extension groove 41, and the extension plate 5 will overcome the tension spring 42 and move away from the bottom of the extension groove 41, thereby increasing the total length of the plurality of curved plates 4 in the strip, so that the insertion hole 61 on the first connecting rod 6 is better aligned with the movable hole 71, thereby facilitating the docking of the interface, and after the connection of the last two curved plates 4 is completed, a ring is formed, and then the plurality of curved plates 4 in the ring are loosened, and the extension plate 5 will retract into the extension groove 41 under the pull of their respective tension springs 42, thereby realizing the tightening of the plurality of curved plates 4 in the ring, and realizing the adjustment of the size of the plurality of curved plates 4 in the ring to adapt to the outer wall of the pipe. After tightening, the plurality of curved plates 4 in the ring better fit the outer wall of the pipe, thereby ensuring the vibration effect of the vibrator 1 on the pipe.

[0034] Example 6: A pressure relief groove 43 is provided inside the arc-shaped plate 4; a first pressure relief hole 44 is provided through the pressure relief groove 43 near one end of the outer wall of the arc-shaped plate 4; a first pressure relief rod 45 moves in the gap inside the first pressure relief hole 44; the other end of the pressure relief groove 43 is connected to the bottom of the two extension grooves 41 through the second pressure relief hole 46; the extension plate 5 is connected to the extension groove 41 in a sliding and sealing manner; the communication position between the pressure relief groove 43 and the first pressure relief hole 44 is abutted against the pressure relief ball 48 through a pressure relief spring 47; the first pressure relief rod 45 is fixedly connected to the pressure relief ball 48.

[0035] Before the multiple curved plates 4 in the strip are finally connected to form a ring, the multiple curved plates 4 in the strip are pulled. After being pulled, the extension plate 5 will overcome the tension of the tension spring 42 and move away from the bottom of the extension groove 41. The extension plate 5 will gradually be pulled out of the extension groove 41. In the process of the extension plate 5 moving away from the extension groove 41, the internal space of the extension groove 41 will expand to form a negative pressure. The outside air will enter along the first pressure relief hole 44, and the outside air will push the pressure relief ball 48 open, so that the first pressure relief hole 44 is opened, and the outside air The pressure relief ball 48 is pressed against the position where the first pressure relief hole 44 and the pressure relief groove 43 are connected, so that the first pressure relief hole 44 is closed, so that the gas in the extension groove 41 cannot be discharged along the first pressure relief hole 44, so that the extension plate 5 cannot be discharged. As the tension spring 42 is pulled back into the extension groove 41, the extension plate 5 is kept in the expanded state, and the multiple strip-shaped arc plates 4 are kept in the growth state, so that the final joint connection is carried out without having to pull the multiple strip-shaped arc plates 4 all the time, which is convenient for operation and installation; the multiple strip-shaped arc plates 4 form a ring after the final interface connection, and then press the multiple first pressure relief rods 45. When pressed, the first pressure relief rods 45 will overcome the pressure relief spring 47 to push the pressure relief ball 48 away, so that the first pressure relief rods 45 can be opened. When the hole 44 is opened, the tension spring 42 will pull the extension plate 5 back into the extension groove 41, and the gas in the extension groove 41 will flow out along the second pressure relief hole 46, the pressure relief groove 43 and the first pressure relief hole 44, and the multiple first pressure relief rods 45 are all pressed down to achieve the tightening of the multiple annular arc plates 4; after the multiple annular arc plates 4 are removed, the multiple annular arc plates 4 are pulled to expand outward, so that when the multiple arc plates 4 are in an expanded and relaxed state, it is convenient to disassemble the first connecting rod 6 and the second connecting rod 7.
