Background Art

[0002] Mine dust refers to the general term for various rock and mineral particles generated during the construction and production of mines. It is extremely harmful and can harm human health in polluted workplaces, causing pneumoconiosis and skin diseases.

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. In addition, in the drawings, the thickness of the components may be exaggerated or reduced in order to effectively describe the technical content.

[0031] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] like Figure 2 As shown, in some embodiments, the atomizing device for preparing blasting dust suppressant includes: a delivery pipe 1, an atomizing nozzle 2 and a pump body 3; the pump body 3 delivers the organosilicon defoaming agent through the delivery pipe 1, and atomizes the organosilicon defoaming agent through the atomizing nozzle 2 and sprays it into the stirred mixed solution.

[0033] Research has found that if the delivery pressure of the silicone defoamer is too high during the delivery process, it is easy to cause the silicone defoamer to "float oil".

[0034] Therefore, in order to solve the technical problems found by the above inventors, Figure 3 As shown, this embodiment provides a solution specifically for solving the above-mentioned problem, which is as follows: by reducing the delivery pressure in the delivery pipe 1, the "oil floating" phenomenon caused by excessive pressure during the delivery of the silicone defoaming agent can be prevented; at the same time, in order to ensure the force required for the atomizing nozzle 2 to atomize the silicone defoaming agent, a plurality of baffles 23 are arranged in the atomizing nozzle 2 to reduce the cross-sectional area of ​​the flow channel 22, thereby increasing the pressure of the silicone defoaming agent in the atomizing nozzle 2 to ensure the atomization requirements.

[0035] Specifically, the atomizing nozzle 2 includes: a nozzle body 21, which is axially provided with a flow channel 22; a plurality of baffles 23, which are arranged circumferentially on the inner wall of the flow channel 22 and radially inserted into the inner wall of the flow channel 22; and a plurality of adjusting sliders 24, which are located in the nozzle body 21 and abut against the corresponding baffles 23 to push the corresponding baffles 23 to protrude from the inner wall of the flow channel 22; wherein when oil blocks are adhered to the protruding portion 231 of the baffle 23, the flow velocity in the flow channel 22 increases to reduce the pressure at the adjusting slider 24, so that the adjusting slider 24 drives the baffle 23 to retreat.

[0036] In this embodiment, since the organosilicon defoaming agent needs to be pressurized and atomized and sprayed out in the atomizing nozzle 2, the organosilicon defoaming agent will still produce the "floating oil" phenomenon at the baffle 23 of the atomizing nozzle 2, so that oil lumps are adhered to the baffle 23; when oil lumps are adhered to the baffle 23, the pressure in the atomizing nozzle 2 will increase, causing the "floating oil" phenomenon to intensify, so the oil lumps adhered to the baffle 23 need to be processed.

[0037] Specifically, by providing an adjusting slider 24 in the nozzle body 21 to abut against the baffle 23, when oil lumps are adhered to the baffle 23, the flow rate of the silicone defoaming agent in the flow channel 22 will increase, so that the pressure at the adjusting slider 24 will be reduced, that is, the adjusting slider 24 drives the baffle 23 to retreat, and the pressure on the silicone defoaming agent is reduced by expanding the cross-sectional area of ​​the flow channel 22. At the same time, the oil lumps on the baffle 23 are cleaned by the retreat of the baffle 23.

[0038] like Figure 4As shown, in some embodiments, a plurality of installation chambers 211 are opened in the nozzle body 21, and each adjusting slider 24 is respectively arranged in the corresponding installation chamber 211; wherein the baffle 23 is radially inserted into the inner wall of the flow channel 22, and extends into the corresponding installation chamber 211 to abut against the corresponding adjusting slider 24; when the oil block is adhered to the protrusion 231 of the baffle 23, the flow velocity in the flow channel 22 increases to reduce the pressure in the installation chamber 211, so that the adjusting slider 24 drives the baffle 23 to retreat.

[0039] In some embodiments, a first spring 212 and a second spring 213 are disposed in the installation chamber 211 ; wherein the second spring 213 pulls the baffle 23 to move toward the installation chamber 211 ; the first spring 212 pushes the adjusting slider 24 to resist the baffle 23 to push the baffle 23 out of the inner wall of the flow channel 22 .

[0040] In this embodiment, the function of the second spring 213 is to pull the baffle 23 to prevent the baffle 23 from detaching; the function of the first spring 212 is to push the adjusting slider 24 to resist the baffle 23 to stabilize the position of the baffle 23; wherein the adjusting slider 24 and the baffle 23 are fitted together through the inclined surface, when the adjusting slider 24 moves backward, the baffle 23 will retract, and when the adjusting slider 24 moves forward, the baffle 23 will extend.

[0041] In some embodiments, the installation chamber 211 is located at the end of the first spring 212 and is provided with a channel 214 connected to the flow channel 22; when the flow velocity in the flow channel 22 increases, the negative pressure of the installation chamber 211 on one side of the first spring 212 drives the adjusting slider 24 to retreat, that is, the baffle 23 retreats; and when the flow velocity in the flow channel 22 is reset, the adjusting slider 24 drives the baffle 23 to reset.

[0042] In this embodiment, when oil blocks are adhered to the baffle 23, the flow rate of the silicone defoaming agent in the flow channel 22 will increase, and the pressure in the installation chamber 211 will decrease, causing the adjustment slider 24 to retreat, and the baffle 23 will retract.

[0043] In this embodiment, when the oil blocks adhered to the baffle 23 are cleared, the flow rate in the flow channel 22 is reduced, and the pressure in the installation chamber 211 is reset, so that the adjusting slider 24 moves forward to drive the baffle 23 to reset; wherein, the adjusting slider 24 generates heat due to friction during the reciprocating movement, thereby dissolving the oil blocks remaining on the baffle 23 and bringing them into the container by the silicone defoaming agent solution.

[0044] like Figure 1As shown, at least one embodiment provides a method for preparing an blasting dust suppressant using an atomizing device for preparing an blasting dust suppressant, which comprises the following steps: step S1, dissolving an inorganic salt and a non-ionic surfactant in water to form a colorless transparent solution; step S2, adding anionic surfactants, amphoteric surfactants, and amino alcohol compounds to the colorless transparent solution to obtain a mixed solution; step S3, stirring the mixed solution, and at the same time, spraying an organosilicon defoaming agent on the mixed solution through the atomizing device for preparing an blasting dust suppressant to obtain a colorless or milky white viscous solution, i.e., an blasting dust suppressant.

[0047] In some embodiments, the nonionic surfactant has good wetting properties, which can reduce the surface tension of water, making it easier for water to wet dust particles, thereby improving the dust suppression effect; at the same time, the nonionic surfactant can effectively disperse and stabilize other ingredients during the preparation process, improving uniformity and stability.

[0048] In some embodiments, the amphoteric surfactant is used as a binder to help dust particles stick together and reduce the flying and spreading of dust.

[0056] In this embodiment, the amphoteric surfactant includes any one or more combinations of lauryl betaine, sodium lauryl aminopropionate and imidazoline betaine.

[0057] In this embodiment, the amino alcohol compound includes any one or more combinations of triethanolamine, monoethanolamine and diethanolamine.
