Abstract
Description
Technical Field
[0001] The invention relates to the technical field of dry mist dust suppression components, and in particular to an air tightness detection device and a detection method of the dry mist dust suppression component. Background Art
[0002] In the water mist dust removal system, water mist particles with a diameter below 10 microns are called dry mist. The dry mist dust suppression system is effective in controlling unorganized dust emissions, especially for fine dust, so it is increasingly widely used. The dry mist dust suppression power station is the core part of the dry mist dust suppression system. It brings together the control, regulation, and distribution equipment of water, gas, and electricity to work. Therefore, the centralized and orderly arrangement of various equipment, especially the reasonable and orderly arrangement of the water and gas connection pipelines between various equipment, directly affects the performance of the dry mist dust suppression power station.
[0003] Among the water-gas connection pipelines, the three-way joint is the most commonly used accessory, which has the function of medium diversion. The existing three-way joint is often made of a main pipe and a branch pipe welded vertically. Affected by factors such as welding temperature and uneven joint surface, there may be leakage points at the welding point. Therefore, the three-way joint needs to undergo an air tightness test before leaving the factory. The conventional air tightness test method is to seal each pipe opening of the three-way joint with a sealing cover, fill the pipe with high-pressure gas, and then immerse the entire pipe in water. By observing the bubbles, it is judged whether there is a leak in the welding point. However, it is necessary to manually block each pipe opening in advance, which is time-consuming and laborious. In addition, when the internal air is inflated, the sealing cover is easy to loosen and cause leakage, making the test result inaccurate.
[0004] Therefore, it is necessary to provide an air tightness detection device and a detection method for a dry fog dust suppression component, which can achieve the effect of automatic detection. Summary of the invention

Of course, they are only examples, and the purpose is not to limit the present application.

[0039] See also Figure 1-7 The present invention provides a technical solution: an air tightness detection device and a detection method for a dry fog dust suppression component, comprising a detection chamber 5, a ventilation part, a top plate 7, a lifting part and a sealing component.
[0040] A water-isolating ring 501 is provided inside the detection chamber 5, and test water is provided below the water-isolating ring 501. A material loading circular opening is provided on the upper side of the detection chamber 5;
[0041] The lifting part is arranged in the detection chamber 5, and the lifting part includes a lifting ring 1, and a plurality of guide rods 101 are penetrated and slidably matched in the lifting ring 1, and the upper and lower ends of the guide rods 101 are fixed in the detection chamber 5, and a connecting plate 102 is fixedly connected to the inner side of the lifting ring 1, and a support seat 103 is arranged at the center of the connecting plate 102, and the support seat 103 is used to place the main pipe of the tee body 6 with the branch pipe facing upward;
[0042] The sealing assembly includes a pair of movable sealing plugs 4, and the sealing plugs 4 are adapted to the main pipe through holes of the tee body 6;
[0043] The ventilation part includes an air pump assembly and a ventilation hose 3, the air pump assembly is connected to the ventilation hose 3, and the lower end of the ventilation hose 3 is similarly provided with a sealing plug 2 303, and a ventilation hole is provided on the middle side of the sealing plug 2 303, the sealing plug 2 303 is adapted to the branch pipe of the three-way body 6, and the upper end of the sealing plug 2 303 is fixedly connected with a lifting plate 302, and an electric telescopic rod 301 is provided between the lifting plate 302 and the top plate 7.
[0044] First, the tee body 6 to be tested is placed on the support seat 103 manually, with the branch pipe facing upwards, and then a pair of sealing plugs 1 4 are moved relative to each other to block the two ends of the main pipe of the tee body 6, and then the lifting plate 302 and the sealing plug 2 303 are pushed down by the electric telescopic rod 301 to block the branch pipe of the tee body 6, thereby forming a closed space, and then the blocked tee body 6 is driven to descend to below the water isolation ring 501 by the lifting ring 1, so that the tee body 6 is submerged in water, and at the same time the electric telescopic rod 301 controls the lifting plate 302 and the sealing plug 303 to move downwards. The second head 303 follows the movement, thereby maintaining a closed state to ensure accurate detection. At this time, the air pump assembly and the ventilation hose 3 are used to ventilate the three-way body 6. By observing whether bubbles are generated, it is determined whether the air tightness of the three-way body 6 is qualified, and the automatic detection of the three-way body 6 can be achieved. There is no need to manually block the pipe opening, which saves time and effort. After the detection is completed, the lifting ring 1 rises and resets, and a pair of sealing plugs 1 4 and the second sealing plug 303 are reset. The three-way body 6 is loosened, and the staff can remove it and place the next three-way body 6 to be tested;
[0045] Preferably, the detection chamber 5 can be further made of a transparent material or provided with a corresponding observation window, so as to facilitate timely observation of the generated bubbles;
[0046] Preferably, the sealing plugs are all made of rubber material to further enhance the sealing performance.
[0047] A pair of hollow grooves are provided on the inner side of the upper end of the detection chamber 5 , in which a limit plate 502 is slidably fitted. The limit plate 502 is moved by an electric telescopic column, and the opposite surfaces of the pair of limit plates 502 are parallel to the main pipe axis of the tee body 6 .
[0048] Preferably, in order to further ensure the accuracy of the docking between the sealing plug 2 303 and the tee body 6, a pair of limit plates 502 are provided. Specifically, an electric telescopic column is provided inside the detection chamber 5, and the electric telescopic column pushes the pair of limit plates 502 to move relative to each other. The pair of limit plates 502 moves toward the center to align the inclined branch pipe so that it is aligned with the sealing plug 2 303 on the upper side to ensure the stability of the docking.
[0049] One side of the sealing plug 4 is fixedly connected to a special-shaped block 401, one end of the special-shaped block 401 is fixedly connected to a moving rod 402, the moving rod 402 passes through the lifting ring 1 and slides with it, one end of the moving rod 402 is fixedly connected to a moving block 403, a plurality of spring telescopic rods are arranged between the moving block 403 and the outer side of the lifting ring 1, one end of the special-shaped block 401 is provided with an inclined surface, a pair of inclined surfaces of the special-shaped block 401 are arranged oppositely, and a pair of special-shaped blocks 2 2 are slidably matched on the inner side of the lifting ring 1, one end of the special-shaped block 22 is similarly provided with an inclined surface, the special-shaped block 401 and the inclined surfaces of the special-shaped block 22 are adapted to each other, one end of the inclined surface of the special-shaped block 22 is provided with a through groove, and the lower end of the special-shaped block 22 is fixedly connected to a rotating ring 201.
[0050] Preferably, a plurality of spring telescopic rods 1, moving blocks 403 and moving rods 402 are provided to guide the movement of the sealing plug 4, and the spring telescopic rod 1 is provided so that the sealing plug 4 is close to the lifting ring 1 in the initial state, so as not to affect the placement of the tee body 6. When it is necessary to drive a pair of sealing plugs 4 to seal the main pipe of the tee body 6, the rotating ring 201 drives a pair of special-shaped blocks 22 to rotate, and the special-shaped blocks 22 are adapted to the inclined surface of the special-shaped block 401 (such as Figure 4 As shown), the special-shaped block 2 pushes the special-shaped block 1 401 along the inclined surface, so that a pair of special-shaped blocks 1 401 are close to each other and clamped at both ends of the tee body 6 to complete the sealing;
[0051] Preferably, a through groove is provided at one end of the special-shaped block 2 to avoid interference with the moving rod 402 .
[0052] The upper and lower ends of the special-shaped block 2 are provided with square grooves, in which a trapezoidal wedge block 104 is slidably fitted, a spring telescopic rod 105 is arranged between the trapezoidal wedge block 104 and the square groove, and a plurality of triangular grooves 106 are provided on the inner side of the lifting ring 1, and the triangular grooves 106 and the trapezoidal wedge block 104 are mutually clamped.
[0053] Preferably, in order to further ensure the sealing performance and prevent the sealing plug 4 from loosening during detection and causing air leakage, a trapezoidal wedge 104 and a triangular groove 106 are provided. Specifically, the two can be engaged with each other. When the rotating ring 201 rotates and the special-shaped block 22 drives the special-shaped block 401 to move, the trapezoidal wedge 104 contacts the triangular groove 106, and the inclined surfaces of the two contact, so that the trapezoidal wedge 104 is forced to be retracted into the square groove for evasion until the sealing plug 4 seals the two ends of the tee body 6. At this time, the trapezoidal wedge 104 pops out and is stuck in the current triangular groove 106. The triangular groove 106 restricts the trapezoidal wedge 104 and prevents it from moving in the opposite direction, that is, the special-shaped block 22 cannot be reset and moved, so that the current position of the sealing plug 4 can be fixed to maintain the sealing state and the sealing stability is strong.
[0054] A rotating plate 202 is fixedly connected to the middle side of the rotating ring 201, a torque sleeve 203 is fixedly connected to the lower end of the rotating plate 202, an internal thread is provided on the inner side of the torque sleeve 203, a threaded rod 204 is threadedly connected to the lower end of the torque sleeve 203, and the threaded rod 204 is driven to rotate by the motor assembly.
[0055] Preferably, when the lifting ring 1 needs to be driven to lift, a torque sleeve 203 and a threaded rod 204 are provided. Specifically, the two are threadedly connected. When the threaded rod 204 rotates counterclockwise relative to the torque sleeve 203, the lifting ring 1 can be moved downward under the guidance of the guide rod 101. On the contrary, when the threaded rod 204 rotates clockwise relative to the torque sleeve 203 (such as Figure 3 As shown), the lifting ring 1 is driven to reset upward;
[0056] Preferably, the upper end of the torque sleeve 203 is fixedly connected to the rotating plate 202, that is, when the threaded rod 204 rotates clockwise, the upper end surface of the lifting ring 1 contacts the upper end of the detection chamber 5 and cannot continue to rise. Therefore, the rotation of the threaded rod 204 cannot drive the lifting ring 1 to move upward, but the threaded rod 204 rotates clockwise to transmit torque through the torque sleeve 203, driving the rotating ring 201 to rotate synchronously, and the rotating ring 201 drives a pair of special-shaped blocks 22 to move, thereby pushing the special-shaped block 1 401 to achieve the sealing of the sealing plug 1 4. The sealing operation is performed. At this time, the trapezoidal wedge block 104 is also stuck in the triangular groove 106, and the rotating ring 201 cannot be rotated counterclockwise to reset (nor can it be rotated clockwise). At this time, the threaded rod 204 rotates counterclockwise again, while the rotating ring 201 and the torque sleeve 203 cannot rotate counterclockwise at this time, so they remain fixed. The threaded rod 204 rotates relative to the torque sleeve 203, thereby driving the lifting ring 1 to descend, so that the tee body 6 is immersed in water for inspection. After the inspection is completed, the threaded rod 204 rotates clockwise again, thereby driving the lifting ring 1 to move upward and reset;
[0057] In summary, the sealing work of the three-way body 6 is realized by the rotation of the threaded rod 204, and the lifting and lowering of the lifting ring 1 is also driven, which has a high degree of automation and strong practicality.
[0058] A vertical hole is provided between the upper and lower square grooves, a magnet block 208 is fixedly connected between the upper and lower trapezoidal wedge blocks 104, and a magnetic metal is provided at the other end of the vertical hole. When the magnet block 208 and the magnetic metal contact each other, the two are attracted to each other, and the trapezoidal wedge block 104 is retracted into the square groove.
[0059] Preferably, when the tee body 6 needs to be loosened and removed, the magnet block 208 drives the pair of trapezoidal wedges 104 to move, so that the trapezoidal wedges 104 are away from the triangular grooves 106, and the clamping state is released, and the special-shaped block 2 can move counterclockwise, thereby loosening the special-shaped block 1 401, so that the sealing plug 1 4 is reset, and the tee body 6 is loosened;
[0060] Preferably, a magnetic metal is provided in the vertical hole, and the magnet block 208 moves along the vertical hole until the two contact and adsorb each other, thereby fixing the position of the trapezoidal wedge block 104 .
[0061] One end of the special-shaped block 2 is fixedly connected with a fixing plate 205, and a square opening 206 is opened through the fixing plate 205. A triangular wedge block 110 is slidably fitted in the square opening 206. A pressing rod 111 is fixedly connected to the lower end of the triangular wedge block 110. The pressing rod 111 passes through the square opening 206 and slidably fits therewith. The pressing rod 111 passes through the rotating ring 201 and extends to the lower side thereof.
[0062] A horizontal hole 207 is provided at one end of the middle side of the vertical hole, a side plate 209 is fixedly connected to the middle side of the magnet block 208, the side plate 209 is slidably matched with the horizontal hole 207, a driving block 210 is fixedly connected to one end of the side plate 209, the driving block 210 extends into the square opening 206, and a slope matching the triangular wedge block 110 is provided at the lower end of the driving block 210;
[0063] A support ring 8 is fixedly connected to the lower end of the detection chamber 5 , and the support ring 8 is matched with the pressing rod 111 .
[0064] Preferably, when it is necessary to drive the magnet block 208 to move so as to release the clamping state of the trapezoidal wedge block 104, a pressing rod 111 is provided. Specifically, when the lifting ring 1 drives the three-way body 6 to descend and is immersed in water for detection, there is a distance difference between the pressing rod 111 and the support ring 8. When the detection is completed, the lifting ring 1 continues to descend so that the pressing rod 111 contacts the support ring 8, the pressing rod 111 and the triangular wedge block 110 remain stationary, and the driving block 210 moves downward relative to it so that the driving block 210 slides along its inclined surface, and the driving block 210 drives the side plate 20 9 and the magnet block 208 move to release the clamping state of the trapezoidal wedge block 104 and the magnet block 208 is adsorbed and cannot be reset. Then the lifting ring 1 rises and resets. When the lifting ring 1 rises to the upper side of the water-blocking ring 501 (at this time, there is a distance difference between the upper end surface of the lifting ring 1 and the upper end of the detection chamber 5), the rotating ring 201 can rotate counterclockwise to separate a pair of sealing plugs 4 from each other. The staff can remove the tee body 6 to complete the unloading work. The degree of automation is high and no additional drive component is required to control the trapezoidal wedge block 104 to release the clamping state with the triangular groove 106.
[0065] A recessed groove is provided at the upper end of the fixed plate 205, and a triangular wedge block 107 is slidably fitted in the square opening 206. A guide column 108 is fixedly connected to the upper end of the triangular wedge block 107. The guide column 108 passes through the square opening 206 and slidably fits therewith. A pressing block 109 is fixedly connected to the upper end of the guide column 108. When the pressing block 109 is in the recessed groove, the upper end surface is flush with the special-shaped block 2.
[0066] Preferably, since the magnet block 208 and the magnetic metal are attracted to each other, an external force is required to separate the two so that the trapezoidal wedge block 104 can be reset and re-engaged with the triangular groove 106. Therefore, a pressing block 109 is provided. Specifically, a spring member is provided between the pressing block 109 and the sinking groove so that the pressing block 109 is away from the sinking groove under normal conditions. In addition, in the above embodiment, when the lifting ring 1 rises to the upper side of the water-blocking ring 501, there is a distance difference between the upper end face of the lifting ring 1 and the upper end of the detection chamber 5. The existence of this distance difference prevents the pressing block 109 from being pressed down. After the tee body 6 is unloaded, the staff places the next tee body 6, and then the rotating ring 201 can drive the special-shaped block 2 2 to move clockwise again to push the special-shaped block 101, so that the sealing plug 104 directly seals the new three-way body 6. After the sealing is completed, the threaded rod 204 can rotate relative to the torque sleeve 203, so that the lifting ring 1 continues to rise, so that the pressing block 109 is pressed by the upper end of the detection chamber 5, thereby pushing the triangular wedge block 107 to move downward, and the triangular wedge block 107 is pushed along the upper end inclined surface of the driving block 210, so that the magnet block 208 and the magnetic metal are separated from each other, and the trapezoidal wedge block 104 can be reset and re-engaged with the triangular groove 106, and then the threaded rod 204 can drive the lifting ring 1 to descend for a new round of detection work, and so on and so forth, thereby realizing the lifting and lowering of the lifting ring 1 to automatically control the engaging state of the trapezoidal wedge block 104, with a high degree of automation and strong practicality.
