Description

Technical Field

[0001] This utility model relates to the field of dry fog dust suppression technology, specifically to an anti-icing device for a nozzle used in dry fog dust suppression. Background Technology

[0002] Dry fog dust suppression technology captures dust by creating a mist-like spray. The water mist combines with airborne dust particles to form agglomerates, which then settle due to gravity, thus suppressing dust at its source. The dust suppression efficiency is directly affected by the control of the water mist particle size and the stability of the nozzle structure.

[0003] Among them, the existing patent with announcement number CN218011819U discloses an anti-icing device for a nozzle used for dry fog dust suppression. When the nozzle body is used for dust suppression, when water flows into the nozzle body from the water inlet pipe, the impact force of the water flow causes the drainage component to seal the drainage hole, allowing water to spray normally. After use, the water flow stops, the drainage component resets and separates from the drainage hole, and the residual water in the nozzle body can be discharged through the drainage hole. At the same time, when the temperature is low, the heating component can heat the water flow entering the nozzle body. The overall structure has a relatively good anti-freezing effect.

[0004] However, while this solution achieves basic antifreeze functionality, empirical analysis reveals the following technical problems: Although the device can drain residual liquid from inside the nozzle body through the drain hole, some water stains still remain on the inner wall of the nozzle body during actual use. In low temperatures, these water stains cannot dry quickly enough and will still freeze, clogging the nozzle orifices and affecting the spray effect. Furthermore, the fixed nozzle structure causes the orifices to face upwards, making it prone to condensation and secondary freezing overnight.

[0005] To address the aforementioned technical bottlenecks, there is an urgent need to develop new anti-icing devices. Utility Model Content

[0006] The present invention aims to provide an anti-icing device for a dry fog dust suppression nozzle, in order to solve the technical problem in the existing device where residual water stains on the inner wall of the dry fog dust suppression nozzle freeze at low temperatures, causing the nozzle orifice to become blocked and affecting the spraying effect.

[0007] The basic solution provided by this utility model is as follows: an anti-icing device for a dry fog dust suppression nozzle, including a diversion pipe, with multiple sets of fixed pipes arranged on both the left and right sides of the diversion pipe, and atomizing nozzles fixedly connected to the surface of the fixed pipes. An extension pipe is fixedly connected between every two sets of fixed pipes, and a sealing head is fixedly connected to one end of the outermost fixed pipe. A drying module is arranged on the side of the diversion pipe, and the drying module includes a first connector, a first valve, a second connector, a second valve, an air inlet hose, and a heating fan. A water inlet hose is fixedly connected to the rear end of the first connector.

[0008] Effect: The inlet hose is used to deliver water to the inside of the diversion pipe. The diversion pipe splits the water flow into the fixed pipes on both sides and sprays it outward through the atomizing nozzle. When not in use, the first valve is closed and the second valve is opened. The heating fan delivers hot air to the inside of the atomizing nozzle to drain any residual water inside the nozzle, thus preventing water residue from remaining inside the nozzle. The hot air also dries the inside of the atomizing nozzle, thereby preventing ice from forming inside the nozzle body.

[0009] Furthermore, the first connector is fixedly connected to the rear side of the diversion pipe; the first valve is fixedly installed inside the first connector; a high-pressure water pump is provided at the rear end of the water inlet hose, and the rear end of the water inlet hose is fixedly connected to the outlet end of the high-pressure water pump.

[0010] Effect: The high-pressure water pump is used to draw water and deliver it through the inlet hose to the inside of the distribution pipe.

[0011] Furthermore, the second connector is fixedly connected to the front side of the diverter pipe, the second valve is fixedly installed inside the second connector, the front end of the second connector is fixedly connected to the front end of the air inlet hose, and the rear end of the air inlet hose is fixedly connected to the exhaust port of the heating fan.

[0012] Effect: The heating fan is used to draw in air and deliver it through the intake hose to the inside of the split pipe, while simultaneously heating the air during the air drawing process.

[0013] Furthermore, connecting pipes are fixedly connected to both ends of the diversion pipe, and the connecting pipes are fixedly connected to the fixed pipe.

[0014] Furthermore, an adjustment component is provided on the side of the extension tube.

[0015] Furthermore, the adjustment assembly includes a retaining ring, a first connecting plate, a retaining plate, a second connecting plate, and a locking screw; the retaining ring is fixedly connected to the surface of the extension tube.

[0016] Furthermore, the first connecting plate is fixedly connected to the side of the fixing ring, the second connecting plate is fixedly connected to the side of the fixing plate, and the first connecting plate is snapped into the inner side of the second connecting plate.

[0017] Effect: The first connecting plate rotates around the second connecting plate, which in turn drives the split pipe, extension pipe and atomizing nozzle to rotate around the second connecting plate, making it easy to adjust the angle of the atomizing nozzle. At the same time, when not in use, the atomizing nozzle is rotated to the lower side to prevent dew from dripping into the nozzle at night and causing it to freeze.

[0018] Furthermore, the lower end of the first connecting plate is provided with a first insertion hole, and a rubber gasket is fixedly connected to the front end of the inner side of the second connecting plate; the front end of each of the second connecting plates is provided with a second insertion hole; the locking screw passes through the first insertion hole and the second insertion hole.

[0019] Furthermore, a locking block is fixedly connected to the surface of the second connecting plate at the left end of the second insertion hole; the locking block has a threaded hole inside, and the left end of the locking screw is threadedly connected to the threaded hole.

[0020] Effect: The locking screw is inserted through the first and second insertion holes to position the first connecting plate. At the same time, the left end of the locking screw is threaded into the threaded hole to lock and fix the first and second connecting plates, thus maintaining the stability of the atomizing nozzle.

[0021] The advantages of this utility model are:

[0022] This utility model discloses an anti-icing device for nozzles used in dry fog dust suppression, which effectively solves the problem of nozzle icing in low-temperature environments, ensuring the effectiveness of dry fog dust suppression. The key points are:

[0023] First, through the independent control of the first valve (water flow channel) and the second valve (hot air channel), this device can quickly switch between working and maintenance drying states. When the first valve is closed and the second valve is opened, the hot air generated by the heating fan can enter the nozzle system in reverse, forming a forced hot air drying path. The hot air is delivered to the interior of the atomizing nozzle, which can drain any residual water inside the nozzle, preventing water residue and drying the interior of the nozzle, thus preventing ice formation inside the nozzle body. Furthermore, the hot air, through a three-dimensional pipe network system consisting of a distribution pipe, connecting pipe, and fixed pipe, can act on multiple sets of atomizing nozzles simultaneously, achieving high drying efficiency.

[0024] Secondly, the adjustment assembly adopts a rotating fit structure between the first connecting plate and the second connecting plate. By rotating the first connecting plate around the second connecting plate, the angle of the atomizing nozzle can be easily adjusted. When not in use, the atomizing nozzle can be rotated to the lower side to facilitate quick drainage of internal water stains and prevent condensation from falling into the nozzle and causing ice formation. Furthermore, the locking screw and threaded hole provide double fixation, ensuring both adjustment flexibility and mechanical stability. Attached Figure Description

[0031] The following detailed explanation illustrates the specific implementation methods:

[0032] The basic implementation examples are as follows: Figure 1 , Figure 2 and Figure 3 As shown: An anti-icing device for a dry fog dust suppression nozzle includes a diverter pipe 1, with multiple sets of fixed pipes 2 on both the left and right sides of the diverter pipe 1, and connecting pipes 17 fixedly connected to both the left and right ends of the diverter pipe 1, the connecting pipes 17 being fixedly connected to the fixed pipes 2.

[0033] Atomizing nozzles 21 are fixedly connected to the surface of the fixed pipe 2. An extension pipe 22 is fixedly connected between every two sets of fixed pipes 2. A sealing head 23 is fixedly connected to one end of the outermost fixed pipe 2. A drying module is provided on the side of the diversion pipe 1. The drying module includes a first connector 11, a first valve 12, a second connector 14, a second valve 15, an air inlet hose 16, and a heating fan 19. A water inlet hose 13 is fixedly connected to the rear end of the first connector 11.

[0034] The first connector 11 is fixedly connected to the rear side of the diversion pipe 1; the first valve 12 is fixedly installed inside the first connector 11; a high-pressure water pump 18 is provided at the rear end of the water inlet hose 13, and the rear end of the water inlet hose 13 is fixedly connected to the outlet end of the high-pressure water pump 18.

[0035] The second connector 14 is fixedly connected to the front side of the diversion pipe 1, the second valve 15 is fixedly installed inside the second connector 14, the front end of the second connector 14 is fixedly connected to the front end of the air inlet hose 16, and the rear end of the air inlet hose 16 is fixedly connected to the exhaust port of the heating fan 19.

[0036] During the installation of this device, firstly, connect the two sets of fixed pipes 2 to the two sets of connecting pipes 17, fix the two sets of atomizing nozzles 21 on both sides of the diversion pipe 1, then connect the extension pipe 22 to one end of the outer side of the fixed pipe 2, and then connect the atomizing nozzle 21 to one end of the outer side of the extension pipe 22, and so on. The corresponding number of atomizing nozzles 21 can be installed according to the actual usage. In addition, the sealing head 23 is connected to the outer end of the outermost fixed pipe 2.

[0037] In practical applications, this anti-icing device can include two operating modes.

[0038] Dust suppression operation mode: When using the atomizing nozzle 21, firstly open the first valve 12 and close the second valve 15. At this time, start the high-pressure water pump 18. The high-pressure water pump 18 draws water and inputs the water flow into the inside of the diversion pipe 1 through the water inlet hose 13 and the first connector 11. Then, through multiple sets of fixed pipes 2 and extension pipes 22, the water flow is dispersed into the inside of multiple sets of atomizing nozzles 21. The water flow is sprayed outward in a mist form through the atomizing nozzles 21 to reduce dust in the surrounding area.

[0039] Drying maintenance mode: When the atomizing nozzle 21 is not in use, close the first valve 12 and open the second valve 15. At this time, start the heating fan 19. The heating fan 19 draws in the outside air and heats it. Then, the hot air is delivered to the inside of the split pipe 1 through the air inlet hose 16. The hot air is then dispersed into the inside of multiple atomizing nozzles 21 through the split pipe 1. The water remaining inside the atomizing nozzle 21 is sprayed out and dried by the hot air, effectively avoiding water stains and preventing ice formation inside the atomizing nozzle 21.

[0040] Furthermore, such as Figure 2 , Figure 4 and Figure 5 As shown, an adjustment component is provided on the side of the extension tube 22.

[0041] The adjustment assembly includes a retaining ring 3, a first connecting plate 31, a fixing plate 4, a second connecting plate 41, and a locking screw 46; the retaining ring 3 is fixedly connected to the surface of the extension tube 22. The first connecting plate 31 is fixedly connected to the side of the retaining ring 3, and the second connecting plate 41 is fixedly connected to the side of the fixing plate 4, with the first connecting plate 31 snapped into the inner side of the second connecting plate 41.

[0042] The lower end of the first connecting plate 31 is provided with a first insertion hole 32, and a rubber gasket 42 is fixedly connected to the front end of the inner side of the second connecting plate 41; the front end of the second connecting plate 41 is provided with a second insertion hole 43; the locking screw 46 passes through the first insertion hole 32 and the second insertion hole 43.

[0043] A locking block 44 is fixedly connected to the surface of the second connecting plate 41 at the left end of the second insertion hole 43; the locking block 44 has a threaded hole 45 inside, and the left end of the locking screw 46 is threadedly connected to the threaded hole 45.

[0044] Meanwhile, during use, tightening the locking screw 46 and the locking block 44 will lock and fix the first connecting plate 31 and the second connecting plate 41, maintaining the stability of the atomizing nozzle 21 during use. After slightly loosening the locking screw 46, the diverter tube 1 can be rotated to adjust the angle of the atomizing nozzle 21, improving ease of use.

[0045] In addition, during the drying process of the atomizing nozzle 21, the locking screw 46 can be loosened slightly first, and the multiple sets of atomizing nozzles 21 can be rotated to the lower side. At this time, the nozzles at the end of the atomizing nozzle 21 are in a downward position. Under the action of high-speed airflow, the residual water inside can be quickly discharged, further improving the drainage speed and facilitating the rapid drying of the inside of the atomizing nozzle 21.

[0046] In the dry maintenance mode, the atomizing nozzle 21 can be rotated to the lower side by rotating the first connecting plate 31 around the second connecting plate 41, which facilitates the quick drainage of internal water stains and prevents dew droplets in the air from falling into the nozzle and causing icing.

[0047] This embodiment provides an anti-icing device for nozzles used in dry fog dust suppression, which can effectively solve the problem of nozzle icing in low-temperature environments and ensure the effectiveness of dry fog dust suppression.
