DETAILED DESCRIPTION

[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0053] The core of the present invention is to provide a spraying operation system. By setting up a mixing device, different media can be mixed, and the medium in the mixing device is in a dynamic state during the mixing process, so as to avoid solidification of the mixed medium. In addition, high-pressure gas is released into the spraying system through a gas transmission device to squeeze most of the medium remaining in the mixing device and the spraying device out of the spraying device. Then, the conveying device inputs cleaning liquid to clean the inner wall of the conveying device, the inner wall of the mixing device, the pipeline and the inner wall of the spraying device, so as to effectively avoid the residual medium from adhering to the inner walls of each device in the system.

[0054] Another core of the present invention is to provide a spraying vehicle including the above-mentioned spraying operation system and a spraying operation method applied to the above-mentioned spraying operation system.

[0055] Please refer to Figures 1 to 4 .

[0056] This specific embodiment provides a spraying operation system, including at least two conveying devices 1, a mixing device 2, a spraying device 3 and a gas transmission device, wherein the conveying device 1 is used to convey the medium to be mixed; the feed port of the mixing device 2 is connected to the discharge end of the conveying device 1, and the mixing device 2 is used to stir and mix different media entering the interior thereof; the liquid inlet end of the spraying device 3 is connected to the discharge port of the mixing device 2, and the spraying device 3 is used to spray out the medium mixed by the mixing device 2; the gas transmission device is used to convey high-pressure gas, one end of the gas transmission device is connected to a gas source, and the other end of the gas transmission device is connected to the mixing device 2, so as to clean the interior of the mixing device 2 by means of high-pressure gas.

[0057] In actual use, when different media need to be mixed and then sprayed, first select the number of conveying devices 1 that need to be opened according to the type of media that need to be mixed, and connect different conveying devices 1 to different material boxes for holding the media; convey different media to the mixing device 2 in the required proportion through the conveying device 1, the mixing device 2 stirs and mixes at least two different media, and the spraying device 3 sprays the mixed media from the mixing device 2; after use, close the feed end of the conveying device 1, open the gas transmission device, and allow high-pressure gas to enter the mixing device 2. When the high-pressure gas flows through the inside of the mixing device 2, it will flush the residual medium in the mixing device 2, and the high-pressure gas carrying the residual medium will be sprayed by the spraying device 3, and then the conveying device inputs cleaning fluid to clean the inner wall of the conveying device, the inner wall of the mixing device, the pipeline and the inner wall of the spraying device, thereby effectively preventing the residual medium from adhering to the inner walls of each device in the system. The beneficial effects of the spraying operation system provided by this specific embodiment include:

[0058] 1. At least two different media are mixed by stirring in the mixing device 2. During the stirring process, since the media are always in a dynamic state, solidification of the mixed media can be effectively avoided;

[0059] 2. When the high-pressure gas flows through the interior of the mixing device 2 through the gas transmission device, the residual medium on the inner wall of the mixing device 2 is flushed, and most of the mixed medium remaining in the device 2 can be effectively squeezed out.

[0060] On the basis of the above embodiment, the spraying operation system can also include a pipe cleaning device 4, one end of which is connected to the outlet of the cleaning liquid system, and the other end of which is connected to the conveying device 1, and the pipe cleaning device 4 is used to provide cleaning liquid to the conveying device 1.

[0061] During actual use, when the spraying operation system finishes spraying, the cleaning liquid can be input into the conveying device 1 through the pipeline cleaning device 4. The cleaning liquid enters the mixing device 2 through the conveying device 1 and is sprayed out by the spraying device 3. The cleaning liquid can clean the pipeline of the conveying device 1 and the inside of the mixing device 2, which can effectively prevent the medium from remaining in the pipeline of the conveying device 1 or inside the mixing device 2.

[0062] It should be noted that the type of cleaning liquid in this specific embodiment needs to be determined according to actual conditions and will not be elaborated here.

[0063] In this specific embodiment, by setting up a pipeline cleaning device 4, the pipeline of the conveying device 1 and the inside of the mixing device 2 can be cleaned. Combined with the high-pressure gas of the gas transmission device, the inside of the pipeline of the conveying device 1 or the inside of the mixing device 2 can be effectively cleaned.

[0064] In a specific embodiment, the conveying device 1 can include an electric three-way ball valve, a material box discharge pipe group, a suction pipe group, a liquid conveying component, a flow regulator 13 and a medium discharge pipe group; the first port of the electric three-way ball valve is connected to the pipeline cleaning device 4; one end of the material box discharge pipe group is connected to the second port of the electric three-way ball valve, and the other end of the material box discharge pipe group is connected to the discharge port of the material box; the third port of the electric three-way ball valve is connected to the suction pipe group, and the other end of the suction pipe group is connected to the liquid conveying component, the discharge end of the liquid conveying component is connected to the feed end of the flow regulator 13, the discharge end of the flow regulator 13 is connected to one end of the medium discharge pipe group, and the other end of the medium discharge pipe group is connected to the mixing device 2; the gas transmission device is connected to the medium discharge pipe group.

[0065] Specifically, Figure 2 As shown, two groups of conveying devices 1 can be set, specifically including A liquid conveying device 11 and B liquid conveying device 12, both of which are provided with flow regulator 13, and the conveying device 1 also includes a first control valve 14 and a second control valve 15, and the first control valve 14 and the second control valve 15 are three-way valves; the first port of the first control valve 14 is connected to the flow regulator 13, the second port of the first control valve 14 is connected to the first port of the second control valve 15, and the third port of the first control valve 14 is connected to the discharge end of the pipeline cleaning device 4; the second port of the second control valve 15 is connected to the feed port of the mixing device 2, the third port of one second control valve 15 is connected to the first gas transmission device 108, and the third port of the other second control valve 15 is connected to the second gas transmission device 113; the spraying device 3 includes a gun spraying device 115 and a ground spraying device 116, the discharge port of the spraying device 3 is connected to the third control valve 21, and the other two ports of the third control valve 21 are respectively connected to the gun spraying device 115 and the ground spraying device 116.

[0066] During actual use, the flow rate of the A liquid delivery device 11 and the B liquid delivery device 12 can be controlled by adjusting the flow regulator 13, thereby adjusting the mixing ratio of the two media in the A liquid delivery device 11 and the B liquid delivery device 12; by controlling the opening and closing of different ports of the third control valve 21, it is possible to choose to use the gun spray device 115 and the ground spray device 116 at the same time, or to use one of the gun spray device 115 and the ground spray device 116, which is determined according to actual conditions.

[0067] like Figure 2 As shown, the A liquid conveying device 11 and the B liquid conveying device 12 convey the A liquid and the B liquid to the mixing device 2 respectively, and the flow regulator 13 on the A liquid pipeline and the B liquid pipeline can adjust the A liquid conveying device 11 and the B liquid conveying device 12 in real time to ensure the flow ratio accuracy of the A liquid and the B liquid. After the A liquid and the B liquid enter the mixing device 2 in the required proportion and are stirred and mixed in real time, they are sprayed through the gun spray device 115 or the ground spray device 116; because the A liquid and the B liquid will react chemically after mixing, it is very easy to solidify into blocks and block the pipeline. Therefore, after the spraying operation is completed, the first gas transmission device 108 and the second gas transmission device 113 input high-pressure gas into the pipeline to squeeze out most of the A liquid and the B liquid remaining in the pipeline from the gun spray device 115 or the ground spray device 116, and then the pipeline cleaning device 4 conveys the liquid for cleaning the pipeline into the pipeline to clean the residual liquid in the pipeline that is difficult to be squeezed out by the high-pressure gas, thereby effectively preventing the pipeline from being blocked.

[0068] It should be noted that the mixing device 2 is provided with an agitator for agitating the medium and a rotation speed detector for detecting the rotation speed of the agitator.

[0069] During actual use, in the initial stage, when liquid A and liquid B begin to flow into the mixing device 2, the liquid A conveying device 11 and the liquid B conveying device 12 can be opened to start conveying liquid A and liquid B, and at the same time, the agitator in the mixing device 2 can be turned on; and after the agitator starts working for a preset time, the mixing device 2 is opened to allow the stirred mixed medium to enter the spraying device 3 and be sprayed out, so that liquid A and liquid B are fully mixed in the mixing device 2; specifically, the preset time of the agitator can be set according to the speed detected by the speed detection component, which is determined according to actual conditions.

[0070] In another specific embodiment, Figure 3As shown, one end of the first pipeline cleaning liquid pipe group 104 is connected to the first port on the first electric three-way ball valve 102, and the other end of the first pipeline cleaning liquid pipe group 104 is connected to the liquid outlet of the cleaning liquid system; one end of the first material box discharge pipe group 103 is connected to the second port on the first electric three-way ball valve 102, and the other end of the first material box discharge pipe group 103 is connected to the discharge port on the material box A; the third port on the first electric three-way ball valve 102 is connected to one end of the first suction pipe group 101, and the other end of the first suction pipe group 101 is connected to the suction port on the first liquid conveying component 105; the discharge port on the first liquid conveying component 105 is connected to the feed end on the first flow regulator 106, and the discharge end on the first flow regulator 106 is connected to one end of the first medium discharge pipe group 107; the first medium discharge pipe group 107 is provided with a first gas transmission device 108, and the other end of the first medium discharge pipe group 107 is connected to the feed port on the mixing device 2.

[0071] One end of the second pipeline cleaning liquid pipe group 119 is connected to the first port on the second electric three-way ball valve 117, and the other end of the second pipeline cleaning liquid pipe group 119 is connected to the liquid outlet of the cleaning liquid material box; one end of the second material box discharge pipe group 109 is connected to the second port on the second electric three-way ball valve 117, and the other end of the second material box discharge pipe group 109 is connected to the discharge port on the material box B; the third port on the second electric three-way ball valve 117 is connected to one end of the second suction pipe group 120, and the other end of the second suction pipe group 120 is connected to the suction port on the second liquid conveying component 110; the discharge port on the second liquid conveying component 110 is connected to the feed end on the second flow regulator 111, and the discharge end on the second flow regulator 111 is connected to one end of the second medium discharge pipe group 112; the second medium discharge pipe group 112 is provided with a second gas transmission device 113, and the other end of the second medium discharge pipe group 112 is connected to the feed port on the mixing device 2.

[0072] The discharge port at the lower end of the mixing device 2 is connected to the first port of the third electric three-way ball valve 114, the second port of the third electric three-way ball valve 114 is connected to the gun spray device 115, and the third port of the third electric three-way ball valve 114 is connected to the ground spray device 116; the liquid entering the mixing device 2 through the A pipeline and the B pipeline is fully stirred in the mixing device 2, and then flows from the discharge port at the lower end of the mixing device 2 to the ground spray device 116 or the gun spray device 115, thereby realizing spraying operations on the ground or in the air.

[0073] Preferably, a rotatable nozzle may be provided on at least one of the ground spray device 116 or the gun spray device 115. By adjusting the rotation angle of the nozzle, the spraying range may be expanded, and targeted spraying at a specific location may be achieved.

[0074] In a specific embodiment, the spraying operation system also includes a flexible joint 118, which is used to connect adjacent pipelines in the spraying operation system; when the pipeline is subjected to vibration impact, the pipeline will produce a slight displacement, and the flexible joint 118 between the pipelines uses the allowable displacement to compensate for the displacement between the pipelines, that is, absorbs the impact force of the pipeline; when the pipeline is not subjected to vibration impact, the flexible joint 118 uses its own high elasticity to release the absorbed impact force, thereby ensuring the reliability of the pipeline connection.

[0075] Based on the above embodiments, a pressure detection device and an early warning mechanism may be provided in the gas transmission device. When the pressure information detected by the pressure detection device is greater than the maximum value of the preset pressure range or less than the minimum value of the preset pressure range, the early warning mechanism issues a warning message so as to timely obtain the pressure information of the gas transmitted in the gas transmission device and facilitate timely adjustments.

[0076] On the other hand, the spraying operation system may further include a liquid leakage detection rope arranged on the conveying device 1 , and the liquid leakage detection rope is arranged along the extending direction of the pipeline in the conveying device 1 .

[0077] During actual use, when leakage occurs in the pipeline of the conveying device 1, the leakage detection rope can obtain leakage information in time, which is convenient for the staff to deal with it in time, avoids material waste, and improves safety at the same time.
