Description

Technical Field

[0001] The present application relates to the field of water mist dust suppressors, and in particular to an antifreeze water mist dust suppressor. Background Art

[0002] The existing dust reduction device is a water mist dust reduction device, which includes a water pipe and an air duct. The water pipe is connected to a nozzle, and the water pipe and the air duct are connected. When dust reduction is performed, water is introduced into the water pipe and high-pressure gas is introduced into the air duct. The high-pressure gas converts the water source in the water pipe into water mist at the nozzle and sprays it out, thereby absorbing dust in the air and causing the dust to fall to the ground, thereby completing the dust reduction.

[0003] The above-mentioned prior art solutions have the following defects: in winter, the existing dust suppression device is easily frozen, thereby causing the dust suppression device to be unusable. Utility Model Content

[0004] In order to prevent the dust suppression device from freezing, the present application provides an antifreeze water mist dust suppressor.

[0005] The above technical objectives of this application are achieved through the following technical solutions:

[0006] An antifreeze water mist dust suppressor comprises a water pipe and an air duct, the air duct is connected to a fan, the water pipe is communicated with the air duct, a plurality of nozzles are arranged on the water pipe, an insulation box is arranged outside the water pipe and the air duct, a heating structure is arranged inside the insulation box, an antifreeze nozzle seat is wrapped outside the nozzle, and a through cavity communicated with the insulation box is opened inside the antifreeze nozzle seat.

[0007] By adopting the above scheme, the water pipe and the air duct are placed in an insulation box, and the heating structure heats the inside of the insulation box, thereby increasing the temperature of the air duct and the water pipe, thereby preventing the water in the water pipe from freezing and causing blockage of the water pipe. At the same time, the antifreeze nozzle seat can also prevent freezing at the nozzle, further preventing the dust suppression device from freezing.

[0008] Optionally, the incubator is under negative pressure or vacuum.

[0009] By adopting the above technical solution, when the insulated box is heated, the gas in the insulated box expands, thereby increasing the air pressure in the insulated box. Too high air pressure in the insulated box may cause safety problems. By setting the insulated box to a negative pressure in advance, the air pressure in the insulated box will not be too high after the temperature in the insulated box increases, thereby improving the safety of the device.

[0010] Optionally, the heating structure includes an electric heating rod.

[0011] By adopting the above technical solution, the inside of the heat preservation box is heated by the electric heating rod, the energy consumption generated by the heating of the electric heating rod is small, and the energy conversion rate is high.

[0012] Optionally, a superconducting liquid is provided in the thermal insulation box for accelerating heat transfer.

[0013] By adopting the above technical solution, the temperature transfer rate in the insulation box is increased by setting the superconducting liquid, and the heat is transmitted more evenly, so that the heating of the air duct and the water pipe is more uniform. At the same time, since the transfer efficiency of the superconducting liquid is higher, the heat loss is also less.

[0014] Optionally, one side of the thermal insulation box is connected to an exhaust duct.

[0015] By adopting the above technical solution, part of the superconducting liquid is injected into the incubator, and then the air in the incubator is extracted through the exhaust pipe to form a negative pressure or vacuum in the incubator. The superconducting liquid is then heated to convert part of the superconducting liquid into gas, so that the superconducting liquid can achieve higher heat transfer efficiency and prevent safety accidents caused by excessive air pressure in the incubator due to heating.

[0016] Optionally, the water pipe is located inside the air duct, and a through opening is opened in the water pipe for connecting with the air duct. The antifreeze nozzle seat is connected with a nozzle, the nozzle is fixedly connected to one end of the nozzle, the other end of the nozzle passes through the water pipe and the air duct, and the end of the nozzle away from the nozzle is located at the through opening, and a connecting hole connected with the inside of the water pipe is opened on the circumferential surface of the nozzle.

[0017] By adopting the above technical solution, the air duct is directly connected to the nozzle, and water enters the nozzle through the connecting hole in the water pipe, thereby controlling the air volume and water volume, so that the wind can blow out the water and reduce the amount of water entering the air duct.

[0018] Optionally, the nozzle includes a connecting shell and an inner tube, the connecting shell is connected to the nozzle, one end of the inner tube is fixedly connected to the connecting shell, a sealing piece is provided at one end of the inner tube away from the connecting shell, the sealing piece blocks the gap between the inner tube and the nozzle, the sealing piece is located below the connecting hole, and a plurality of second through holes are opened on the circumferential surface of the inner tube close to the connecting shell.

[0019] By adopting the above technical solution, the nozzle is connected to the nozzle through the connecting shell, and a sealing member is provided to further prevent water from entering the air duct, so that wind enters the inner tube at the end of the inner tube away from the connecting shell, and water enters the inner tube at the second through hole, so that wind and water converge at the nozzle, so that the wind directly sprays the water, further reducing the amount of water entering the air duct.

[0020] Optionally, the outer circumferential surface of the connecting shell is provided with threads, the inner side of the nozzle is provided with threads, and the nozzle is connected to the nozzle by threads.

[0021] By adopting the above technical solution, the nozzle can be disassembled and replaced, which is convenient for cleaning the inside of the nozzle. At the same time, the nozzle can be replaced according to different situations, so as to adjust the range and distance of the sprayed water mist, which is applicable to more situations.

[0022] Optionally, a sealing ring is provided at the connection between the connecting shell and the nozzle.

[0023] By adopting the above technical solution, the connecting shell and the nozzle are fixed more tightly, preventing wind and water from flowing out through the gap between the connecting shell and the nozzle.

[0024] Optionally, the cross-section of the insulation box is rectangular, and the antifreeze nozzle seat is located on the upper side of the insulation box.

[0025] By adopting the above technical solution, the rectangular insulation box can be placed on the ground so that the antifreeze nozzle is located above the insulation box, which is not easy to tip over.

[0026] In summary, this application has the following technical effects:

[0027] 1. Prevent the dust suppression device from freezing by setting up a heating device and an antifreeze nozzle seat;

[0028] 2. By pumping the heat preservation box into negative pressure or vacuum, the air pressure in the heat preservation box is reduced to prevent the heat preservation box from being heated and causing the air pressure in the heat preservation box to be too high, thereby improving the safety of the dust collector;

[0029] 3. The superconducting liquid is used to make the heat transfer in the incubator more uniform and rapid. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings.

[0035] Reference Figure 1, an antifreeze water mist dust suppressor, comprising a water pipe 1 and an air pipe 2, the water pipe 1 is connected to a water pump, the air pipe 2 is connected to a fan, the water pipe 1 is in communication with the air pipe 2, the water pipe 1 is in communication with a plurality of nozzles 6, an insulation box 3 is arranged outside the water pipe 1 and the air pipe 2, and a heating rod 4 is arranged inside the insulation box 3. When the air pipe 2 and the water pipe 1 need to be heated, the heating rod 4 heats the insulation box 3, so that the temperature of the air pipe 2 and the water pipe 1 is kept above zero degrees, the fan and the water pump are started, the fan blows air into the air pipe 2, the water pump pumps water into the water pipe 1, the wind in the air pipe 2 sprays the water in the water pipe 1 at the nozzle 6, and the sprayed water forms water mist, the water mist absorbs the dust in the air, and makes the dust fall to the ground with the water mist, so as to achieve the dust reduction effect, the heating rod 4 prevents the water in the water pipe 1 from freezing, thereby preventing the dust suppressor from freezing.

[0036] Reference Figure 1 and Figure 3 , the insulation box 3 is filled with superconducting liquid, and an exhaust pipe 31 is connected to the insulation box 3 near the lower side. The superconducting liquid has good thermal conductivity. After the superconducting liquid is heated by the heating rod 4, compared with air, the superconducting liquid can transfer heat to the air duct 2 and the water pipe 1 more quickly, thereby reducing the heat loss during the transfer process, and the heat transfer of the superconducting liquid is more uniform, so that the surface of the air duct 2 and the water pipe 1 in the insulation box 3 is heated more evenly, further enhancing the antifreeze effect. And because the superconducting liquid has a higher thermal conductivity efficiency under low air pressure, part of the superconducting liquid can be filled in the insulation box 3, and then the insulation box 3 is inverted, and the air in the insulation box 3 is extracted through the exhaust pipe 31, so that a vacuum or negative pressure is formed in the insulation box 3, and then the superconducting liquid is heated and heated, and part of the superconducting liquid is converted into gas after heating, further improving the heat transfer efficiency in the insulation box 3.

[0037] Reference Figure 3 A plurality of antifreeze nozzle seats 5 are arranged on the surface of the insulation box 3, and the nozzle 6 passes through the antifreeze nozzle seat 5. A through cavity 51 connected with the insulation box 3 is opened inside the antifreeze nozzle seat 5. Specifically, at least one through hole connected with the through cavity 51 in the antifreeze nozzle seat is opened on the insulation box 3, so that the superconducting liquid can enter the through cavity 51 inside the antifreeze nozzle seat 5 along the through hole to cover the surface of the nozzle, thereby heats the nozzle 6, thereby preventing the nozzle 6 from freezing and causing the dust suppressor to be unusable.

[0038] Reference Figure 2 and Figure 3The water pipe 1 is located inside the air pipe 2, and a through hole 11 communicating with the inside of the air pipe 2 is provided on one side of the water pipe 1. The antifreeze nozzle seat 5 is connected with a nozzle 7, and one end of the nozzle 7 is connected with the antifreeze nozzle seat 5. The end of the nozzle 7 away from the antifreeze nozzle seat 5 passes through the air pipe 2 and the water pipe 1 to reach the through hole 11. When the end of the nozzle 7 reaches the through hole 11, the water pipe 1 and the air pipe 2 are no longer connected through the through hole 11, and the air pipe 2 is connected with the inside of the nozzle 7. A connecting hole 71 communicating with the inside of the water pipe 1 is provided on the circumferential surface of the nozzle 7. The nozzle 6 is arranged at one end of the nozzle 7 connected with the antifreeze nozzle seat 5. The wind in the air pipe 2 enters the nozzle 7 at the through hole 11 and merges with the water entering the nozzle 7 at the connecting hole 71. Then the wind sprays the water into water mist at the nozzle 6, thereby achieving dust reduction. The water pipe 1 and the air pipe 2 are connected via the nozzle 7, thereby reducing the amount of water in the water pipe 1 entering the air pipe 2.

[0039] Reference Figure 1 and Figure 2 The nozzle 6 includes a connecting shell 61 and an inner tube 62. The inner tube 62 is fixedly connected to the center of the connecting shell 61. The outer peripheral surface of the connecting shell 61 is provided with an external thread. The end of the nozzle 7 close to the antifreeze nozzle seat 5 is provided with an internal thread. The connecting shell 61 and the nozzle 7 are connected by threads, which is convenient for cleaning the inside of the nozzle 7. At the same time, nozzles 6 of different specifications can be replaced according to different actual conditions, so as to adjust the range and distance of the water mist. A sealing ring 611 is provided on the outer peripheral surface of the connecting shell 61. The sealing ring 611 blocks the gap between the connecting shell 61 and the nozzle 7 to prevent water and wind from overflowing from the gap between the connecting shell 61 and the nozzle 7. One end of the inner tube 62 is fixedly connected to the connecting shell 61, and a plurality of second through holes 621 are opened on the circumferential surface of the inner tube 62 near the connecting shell 61, so that the nozzle 7 is connected to the inner side of the inner tube 62 through the second through holes 621, and after water enters the nozzle 7 through the connecting hole 71, it enters the inner tube 62 at the second through hole 621. The inner tube 62 is located in the nozzle 7, and the end of the inner tube 62 away from the connecting shell 61 is a sealing member 622. The sealing member 622 seals the gap between the inner tube 62 and the nozzle 6, and the sealing member 622 is located below the connecting hole 71, thereby preventing water from entering the nozzle 7 and directly falling into the air duct 2. After the water in the water pipe 1 enters the nozzle 7 through the connecting hole 71, the blocking member 622 further prevents the water from entering the air duct 2. The water flows into the inner tube 62 at the second through hole 621, merges with the wind in the air duct 2, and is sprayed out at the nozzle 6 along with the wind.

[0040] The specific implementation principle of the present application is as follows: when the temperature is low, the heating rod 4 heats the superconducting liquid in the insulation box 3, and the superconducting liquid transfers the heat evenly to the outside of the air duct 2, and transfers the heat to the water pipe 1 through the air duct 2. At the same time, the superconducting liquid enters the through cavity 51 to heat and insulate the nozzle 6, thereby preventing the dust collector from freezing. When dust reduction is required, start the water pump and the fan, so that the wind enters the nozzle 7 along the air duct 2, and then enters the inner tube 62, and meets the water entering the inner tube 62 in the water pipe 1 at the second through hole 621. Then the wind sprays the water at the nozzle 6 to form a water mist, and the sprayed water mist absorbs the dust in the air and makes the dust fall to the ground along the water mist, thereby completing the dust reduction. Compared with the existing dust reduction equipment, this dust collector can be used when the temperature is low by heating and insulating the air duct 2, the water pipe 1 and the nozzle 6.

[0041] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
