Description

Technical Field

[0001] The invention relates to the field of negative pressure material suction equipment, and in particular to a pulse vibration type anti-blocking pipeline structure. Background Art

[0002] Freight trains transport coal and other goods for extended periods of time. After unloading, residual materials, such as coking coal and iron ore concentrate, often remain in the train compartments. These materials typically require a negative pressure system to collect. Because these residual materials are granular and contain a certain amount of moisture, they easily adhere to or accumulate on the pipe walls, necessitating frequent disassembly, cleaning, and repairs. This increases the workload for staff and prolongs cleaning time.

[0003] The existing solution involves installing a pulse valve on the pipe. Air cannons controlled by the pulse valves directly impact the pipe wall, knocking away any material stuck to it and preventing blockage in the pumping pipe. However, this approach is limited by pipe size and air flow. Within a given pipe cross section, there are only a limited number of locations for air cannons. Essentially, only one air cannon per inflation pipe is required. A single air cannon's impact on the pipe cleaning range is limited, and it cannot completely remove any remaining material stuck to the pipe wall. Summary of the Invention

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more such features, and are used to distinguish between the described features, without distinction of order or importance.

[0036] In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0037] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0038] Please refer to Figures 1 to 6 The present invention provides a pulse vibration anti-blocking pipeline structure, comprising a first pipeline 1, a second pipeline 2 and an anti-blocking unit, wherein the anti-blocking unit comprises a vibration component 3 and a soft lining sheet 4, the vibration component 3 is provided with a pumping channel 30 along the Y axis, the first pipeline 1 is connected to one end of the pumping channel 30, and the second pipeline 2 is connected to the other end of the pumping channel 30;

[0039] The fixed end of the soft lining sheet 4 is arranged on the inner wall of the extraction channel 30, and the free end of the soft lining sheet 4 is in close contact with the inner wall of the first pipe 1 and / or the second pipe 2; the inner wall of the extraction channel 30 is provided with an air inlet 31, and the free end of the soft lining sheet 4 covers the air inlet 31;

[0040] A pulse air duct 32 is provided in the vibration component 3 , and the pulse air duct 32 is communicated with the air inlet 31 , and the pulse air duct 32 is communicated with an external pulse-type inflation device.

[0041] The pulse vibration anti-blocking pipe structure includes a first pipe 1, a second pipe 2 and an anti-blocking unit, and the anti-blocking unit includes a vibration component 3 and a soft inner lining sheet 4. The vibration component 3 is connected to an external pulse inflation device, and intermittent pulse airflow is provided by the pulse inflation device, so that the pulse airflow passes through the pulse air duct 32 and is ejected from the air outlet 31; because the free end of the soft inner lining sheet 4 is close to the inner wall of the first pipe 1 and / or the second pipe 2, and the free end of the soft inner lining sheet 4 covers the air outlet 31, when the pulse airflow is ejected from the air outlet 31, the pulse airflow rushes out at high speed and impacts the corresponding soft inner lining sheet 4, causing the soft inner lining sheet 4 to swing greatly, and the material stuck on the soft inner lining sheet 4 is thrown out and vibrated.

[0042] The above structure is simple to manufacture and can clean the entire pipe cross section by swinging the soft lining sheet 4 in a large range, improve the accumulation of materials inside the first pipe 1 and / or the second pipe 2, inhibit the blockage of the pipe, effectively reduce the number of disassembly, cleaning and maintenance, and thus reduce the workload of the staff.

[0043] Since the pulse vibration anti-blocking pipe structure is applied to the negative pressure suction system, the soft lining sheet 4 will, under the influence of negative pressure, again cling to the inner wall of the extraction channel 30 and cover the air inlet 31 when the pulse inflation device does not input the pulse airflow.

[0044] The first pipe 1 / the second pipe 2 is connected to the suction pipe of the negative pressure suction system, and the second pipe 2 / the first pipe 1 at the other end is connected to the suction pipe of the negative pressure suction device. The negative pressure suction system generates negative pressure when working, so that the material can enter the vibration component 3 from the first pipe 1 / the second pipe 2, and then be transported to the predetermined area through the second pipe 2 / the first pipe 1.

[0045] The negative pressure suction and delivery pipeline can be equipped with a pulse vibration anti-blocking pipeline structure at intervals. The pulse vibration anti-blocking pipeline structure can fully solve the problem of material accumulation in the pipeline and suppress the phenomenon of pipeline blockage.

[0046] Specifically, the soft inner lining sheet 4 includes a plurality of first inner lining sheets 41 and a plurality of second inner lining sheets 42;

[0047] A plurality of first inner lining sheets 41 are circumferentially spaced apart along the inner wall of the extraction channel 30 , wherein the fixed ends of the first inner lining sheets 41 are disposed on the inner wall of the extraction channel 30 , and the free ends of the first inner lining sheets 41 are in close contact with the inner wall of the first pipe 1 ;

[0048] A plurality of second inner lining sheets 42 are arranged along the inner wall of the extraction channel 30 in a circumferential direction. The fixed ends of the second inner lining sheets 42 are arranged on the inner wall of the extraction channel 30 , and the free ends of the second inner lining sheets 42 are in close contact with the inner wall of the first pipe 1 .

[0049] The air inlet 31 includes a plurality of first air holes 311 and a plurality of second air holes 312. The first air holes 311 and the second air holes 312 are arranged at intervals along the circumferential direction of the inner wall of the extraction channel 30. The plurality of first air holes 311 cooperate to form a first annular array, and the plurality of second air holes 312 cooperate to form a second annular array. The first annular array is located on a side of the extraction channel 30 close to the first pipe 1, and the second annular array is located on a side of the extraction channel 30 close to the second pipe 2.

[0050] The number and position of the first inner lining sheets 41 are adapted to the number and position of the first air holes 311, and the number and position of the second inner lining sheets 42 are adapted to the number and position of the second air holes 312; the free end of the first inner lining sheet 41 covers the corresponding first air holes 311, and the free end of the second inner lining sheet 42 covers the corresponding second air holes 312.

[0051] The first inner lining 41 and the second inner lining 42 have the same structure, and the difference lies in the installation direction of the first inner lining 41 and the second inner lining 42. The free end of the first inner lining 41 covers the corresponding first air hole 311, and the free end of the second inner lining 42 covers the corresponding second air hole 312; the first air hole 311 and the second air hole 312 are both connected to the pulse air duct 32. When the pulse airflow is ejected from the first air hole 311 and the second air hole 312, the first inner lining 41 swings greatly to clean the inner wall of the first pipe 1, and the second inner lining 42 swings greatly to clean the inner wall of the second pipe 2. The first pipe 1 and the second pipe 2 can be cleaned at the same time, thereby increasing the cleaning range and increasing the cleaning efficiency.

[0052] A plurality of first air holes 311 and a plurality of second air holes 312 are spaced circumferentially along the inner wall of the extraction channel 30, with the first inner lining sheets 41 covering the corresponding first air holes 311, and the second inner lining sheets 42 covering the corresponding second air holes 312. With the above structure, by providing a plurality of first air holes 311 and a plurality of second air holes 312, in combination with the plurality of first inner lining sheets 41 and the plurality of second inner lining sheets 42, the first inner lining sheets 41 can be evenly distributed throughout the first pipe 1, and the second inner lining sheets 42 can be evenly distributed throughout the second pipe 2, thus avoiding blind spots during cleaning.

[0053] Furthermore, the soft inner lining 4 also includes a fixed ring piece, the fixed end of the first inner lining 41 and the fixed end of the second inner lining 42 are respectively connected to the fixed ring piece, and the fixed ring piece, the first inner lining 41 and the second inner lining 42 are integrally formed; the first inner lining 41 and the second inner lining 42 are fixed to the inner wall of the extraction channel 30 through the fixed ring piece.

[0054] In a specific embodiment of the present invention, the fixed ring, the first inner lining 41, and the second inner lining 42 are integrally formed, and the first inner lining 41 and the second inner lining 42 are fixed to the inner wall of the material extraction channel 30 via the fixed ring. The above structure improves the installation efficiency of the soft inner lining 4. When the soft inner lining 4 needs to be replaced, the fixed ring is directly removed from the inner wall of the material extraction channel 30, and the fixed ring of the new soft inner lining 4 is then installed on the inner wall of the material extraction channel 30.

[0055] Furthermore, the anti-blocking unit also includes a locking ring 5, which is provided with fixed through holes at intervals along the circumferential direction, and the inner wall of the extraction channel 30 is provided with fixed screw holes 33 corresponding to the fixed through holes at intervals, and the fixing ring is provided with a first avoidance hole corresponding to the fixed through hole. The locking ring 5 is detachably connected to the extraction channel 30, and the fixing ring is tightly pressed against the inner wall of the extraction channel 30.

[0056] The locking ring 5 is used to secure the fixed ring to the inner wall of the extraction channel 30, thereby securing the flexible inner lining 4 to the inner wall of the extraction channel 30. In practice, the locking ring 5 and the extraction channel 30 are removably connected via screws, which pass through the fixing through-hole and the first relief hole, and then threadably engage with the fixing screw hole 33. This installation method ensures a stable connection, preventing the flexible inner lining 4 from loosening from the inner wall of the extraction channel 30. Furthermore, removal and installation are simple and quick.

[0057] Optionally, two adjacent first inner lining sheets 41 form a first gap, and two adjacent second inner lining sheets 42 form a second gap. The fixing ring sheet is provided with avoidance gaps 401 at the ends of the first gap and the second gap, respectively.

[0058] The above structure allows for a larger movable space between two adjacent first inner lining sheets 41 / second inner lining sheets 42 , enabling a larger swing range and enhancing the cleaning capability.

[0059] At the same time, since the fixed ring piece, the first inner lining piece 41 and the second inner lining piece 42 are integrally formed, in actual operation, the soft inner lining piece 4 is cut from a whole piece of soft rubber. First, an avoidance notch 401 is set on the soft rubber, and then the soft rubber is divided by the avoidance notch 401 to form a fixed ring piece, several first inner lining pieces 41 and several second inner lining pieces 42. Setting the avoidance notch 401 can facilitate the processing and division of the soft rubber.

[0060] Preferably, the air outlet 31 includes a third air hole 313, and the third air hole 313 is arranged between the first annular array and the second annular array along the circumferential direction. The locking ring plate 5 is provided with a ventilation hole 51 corresponding to the third air hole 313, and the fixed ring plate is provided with a second avoidance hole corresponding to the third air hole 313.

[0061] Since the locking ring 5 is provided with a ventilation hole 51 corresponding to the third air hole 313, and the fixed ring is provided with a second avoidance hole corresponding to the third air hole 313, the pulse airflow will not push the soft lining sheet 4 after being ejected from the third air hole 313, but will directly clean the adhered and compacted materials on the locking ring 5 to avoid blockage of the pipeline of the locking ring 5.

[0062] Specifically, the vibration assembly 3 includes a shell 301 and an inner lining ring 302. The shell 301 is provided with an accommodating cavity, and the inner lining ring 302 is disposed in the accommodating cavity. The material extraction channel 30 is formed by the inner wall of the inner lining ring 302. The outer wall of the inner lining ring 302 is recessed with an annular groove toward the inside. The groove wall of the annular groove and the accommodating cavity form a main air duct 321. The outer side of the shell 301 is provided with an air inlet 320, and the air inlet 320 is connected to the main air duct 321.

[0063] The inner lining ring 302 is provided with a first oblique air duct 322, a straight blowing air duct 323 and a second oblique air duct 324, the first oblique air duct 322 gradually tilts from the outside to the inside of the inner lining ring 302 toward one end of the first pipe 1; the first oblique air duct 322 gradually tilts from the outside to the inside of the inner lining ring 302 toward one end of the second pipe 2; the straight blowing air duct 323 is arranged along the radial direction of the inner lining ring 302; the first oblique air duct 322 is connected to the first air hole 311, the second oblique air duct 324 is connected to the second air hole 312, and the straight blowing air duct 323 is connected to the third air hole 313; the main air duct 321, the first oblique air duct 322, the straight blowing air duct 323 and the second oblique air duct 324 cooperate to form a pulse air duct 32.

[0064] The housing 301 is used to fix and protect the inner liner ring 302 and input pulse airflow into the main air duct 321 through the air inlet 320. In a specific embodiment of the present invention, the housing 301 is provided with two air inlets 320.

[0065] The material of the inner lining ring 302 is nylon. After the pulse airflow enters from the air inlet 320, it enters the first inclined air duct 322, the straight blowing air duct 323 or the second inclined air duct 324 through the main air duct 321; the pulse airflow entering the first inclined air duct 322 will push the first inner lining sheet 41, the pulse airflow entering the second inclined air duct 324 will push the second inner lining sheet 42, and the pulse airflow entering the straight blowing air duct 323 will be used to directly clean the adhered and compacted materials on the locking ring sheet 5.

[0066] Preferably, sealing grooves are provided at both ends of the inner liner ring 302 in the Y-axis direction, and sealing rings 303 are provided in the sealing grooves; and the annular groove is located between the two sealing grooves.

[0067] By adopting the above structure, by setting a sealing groove and a sealing ring 303, the pulse airflow is prevented from leaking from the assembly gap between the outer shell 301 and the inner lining ring 302, and the impact force of the pulse airflow is prevented from being weakened, resulting in a weakening of the swing amplitude of the soft inner lining sheet 4, thereby avoiding the problem of reduced cleaning ability.

[0068] Specifically, the shell 301 includes a shell body 3011, a first flange 3012 and a second flange 3013. The first flange 3012 is detachably connected to the side of the shell body 3011 close to the first pipe 1, and the second flange 3013 is detachably connected to the side of the shell body 3011 close to the second pipe 2; the accommodating cavity is arranged in the shell body 3011, and the first flange 3012 and the second flange 3013 cooperate with each other to fix the liner ring 302 in the accommodating cavity.

[0069] In one embodiment of the present invention, housing 301 secures inner ring 302 within the housing cavity via first and second flanges 3012, 3013. These, combined with the sealing ring on inner ring 302, provide excellent sealing performance, reducing leakage of pulsed airflow through the assembly gap. Furthermore, first and second flanges 3012, 3013 are detachably connected to housing 301 via bolts, facilitating easy installation and removal, and facilitating inspection or replacement of the anti-blocking unit's internal structure.

[0070] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such equivalent variations or substitutions are intended to be encompassed within the scope of the claims of this application.
