Description

Technical Field

[0001] This invention relates to the field of coating spraying technology, and in particular to a method and apparatus for spraying anti-corrosion coatings onto the inner wall of a dust collector hopper. Background Technology

[0002] In solid fuel (such as coal, municipal solid waste, etc.) combustion power generation systems, dust collectors are crucial equipment for flue gas purification. Their working principle involves using methods such as electrostatic collection and bag filtration to separate dust particles from the flue gas and collect them into an ash hopper, thus obtaining clean flue gas. However, acidic gases such as HCl and SO2 in the flue gas easily condense on the inner wall of the dust collector's ash hopper, and the accumulated ash layer also contains a large amount of corrosive elements (such as Cl, S, Na, K, etc.), leading to severe low-temperature corrosion, causing problems such as ash particle adhesion and blockage, and thinning of the ash hopper wall.

[0003] To mitigate the low-temperature corrosion caused by condensed acid, applying an anti-corrosion coating to the inner wall of the ash hopper is a widely used method. Most related technologies employ manual spraying or have workers carry the spraying machine for the sealing operation, which is not only labor-intensive but also detrimental to improving construction efficiency.

[0004] Therefore, there is an urgent need to provide an anti-corrosion coating spraying system for the inner wall of the dust collector hopper to solve the above-mentioned technical problems. Summary of the Invention

[0005] This invention provides a method and apparatus for spraying anti-corrosion coating on the inner wall of a dust collector hopper, which can realize the automated spraying of anti-corrosion coating on the inner wall of the dust collector hopper.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Figure 1This diagram illustrates a process flow illustration of a method for spraying an anti-corrosion coating onto the inner wall of a dust collector hopper according to one embodiment. It is understood that this method can be executed by any device, equipment, platform, or cluster of devices with computing and processing capabilities. Figure 1 As shown, this method is applied to spraying systems (such as...) Figure 3 As shown, the spraying system includes a rotatable base 1, a vertically retractable first support 2, a horizontally retractable second support 3, and a nozzle 4. The base 1 is located at the bottom of the dust collector hopper 10. The first support 2 is vertically fixed to the base 1 and located inside the dust collector hopper 10. The second support 3 is horizontally fixed to the top of the first support 2. The nozzle 4 is rotatably located at the end of the second support 3 away from the first support 2.

[0034] The method includes:

[0035] Step 100: Obtain the spraying task; wherein, the spraying task includes the spraying task of all inner wall surfaces of the dust collector hopper 10 and the spraying task of the target inner wall surface of the dust collector hopper 10.

[0036] Step 102: Based on the spraying task, determine the spraying action of the spraying system to perform the spraying task using the spraying action; wherein, the spraying action includes the action of the base 1, the first support 2, the second support 3 and the nozzle 4.

[0037] In this embodiment, by setting a rotatable base 1, a vertically retractable first support 2, a horizontally retractable second support 3, and a nozzle 4, the spraying action of the spraying system can be determined based on the acquired spraying task, so as to execute the spraying task by using the spraying action, thereby realizing the automatic spraying of anti-corrosion coating onto the entire inner wall of the dust collector hopper 10 to be sprayed.

[0038] Currently, most dust collector hoppers are manufactured by pre-coating metal plates with anti-corrosion paint at the factory, and then bending the metal plates to form the dust collector hopper structure (e.g., an inverted frustum or an inverted square truncated pyramid). However, the inventors creatively discovered during the research and development process that as the usage time increases, the anti-corrosion coating on the inner wall of the dust collector hopper gradually thins and may even disappear in some areas. Currently, most solutions to this technical problem require manual entry into the dust collector hopper for spraying, which is obviously inefficient.

[0039] Therefore, the above technical solution can achieve automatic spraying of anti-corrosion coating onto the entire inner wall of the dust collector hopper 10 to be sprayed.

[0040] It is understood that the functions of rotating the base 1 and retracting the first support member 2 and the second support member 3 can all rely on a drive assembly (not shown in the figure). In some embodiments, the drive assembly includes a first motor, a second motor, and a third motor, wherein the first motor is used to drive the base 1 to rotate, the second motor is used to drive the first support member 2 to retract, and the third motor is used to drive the second support member 3 to retract.

[0041] Of course, the drive assembly can also adopt the principle of pneumatic or hydraulic drive; the specific drive method of the drive assembly is not specifically limited here. Preferably, an electric motor drive is used, which makes the drive more convenient and faster.

[0042] In some embodiments, the first support member 2 and the second support member 3 are both springs, the second motor is connected to the top of the first support member 2 via a first connecting rope (which can be understood as a flexible rope, not shown in the figure), and the third motor is connected to the end of the second support member 3 away from the first support member 2 via a second connecting rope (which can be understood as a flexible rope, not shown in the figure).

[0043] It should be noted that the second motor and the third motor can both be set at the bottom of the first support member 2. However, since the first support member 2 and the second support member 3 are perpendicular to each other, it is necessary to consider setting a fixed pulley at the top of the first support member 2 to turn the second connecting rope.

[0044] Of course, the second motor can be set at the bottom of the first support member 2, and the third motor can be set at the top of the first support member 2, so that there is no need to set a fixed pulley.

[0045] Furthermore, the first and second connecting ropes can be threaded inside or outside the spring, preferably inside. This arrangement reduces the transmission path, thereby ensuring better force transmission.

[0046] Since both the first support member 2 and the second support member 3 are springs, their return or extension can utilize their inertia. In order to coordinate their extension, the flexible first and second connecting ropes are easier to implement than rigid connecting members.

[0047] In some embodiments, the first support member 2 and the second support member 3 are both corrugated pipes, the second motor is disposed at the bottom end of the first support member 2, the second motor is connected to the top end of the first support member 2 through the first rigid member, and the second motor is also used to drive the first support member 2 to extend.

[0048] The top of the first support member 2 is provided with a first mounting base (not shown in the figure), and the third motor is provided on the first mounting base. The third motor is connected to the end of the second support member 3 away from the first support member 2 through the second rigid member. The third motor is also used to drive the second support member 3 to extend.

[0049] In this embodiment, considering that the bellows has almost no rebound force compared to the spring, the connecting part between the motor and the bellows needs to be set as a rigid part so that the first support 2 and the second support 3 can be extended by means of the output force of the motor.

[0050] In some embodiments, both the first support member 2 and the second support member 3 are sleeves, and the second motor is disposed at the bottom end of the first support member 2. The second motor is also used to drive the first support member 2 to extend.

[0051] The top of the first support member 2 is provided with a first mounting base (not shown in the figure), and the third motor is provided on the first mounting base. The third motor is also used to drive the second support member 3 to extend.

[0052] In this embodiment, considering that the expansion and contraction of the sleeve can be directly achieved using the output shaft of the motor, there is no need to set up a connecting piece (specifically a rigid connecting piece).

[0053] In some embodiments, a second mounting base (not shown in the figure) is provided at the end of the second support member 3 away from the first support member 2, and an electric angle adjuster (not shown in the figure) is provided on the second mounting base, and the nozzle 4 is connected to the electric angle adjuster.

[0054] In this embodiment, by providing an electric angle adjuster, the spray adaptability of the nozzle 4 can be further ensured. For example, when the nozzle 4 is at a certain angle (such as...), Figure 4 When the initial spraying of θ) is performed, uneven supply of paint may cause uneven spraying in a certain area of ​​the inner wall of the dust collector hopper 10. At this time, the spraying direction of the nozzle 4 can be adjusted by controlling the electric angle adjuster, so as to more easily achieve uniform spraying of paint.

[0055] In some embodiments, a resistance wire is installed inside the nozzle 4. This configuration allows for rapid spraying of the paint.

[0056] like Figure 3 As shown, in some embodiments, the above-mentioned spraying system further includes a paint supply component 5, which includes a paint tank 51, an air pump 52 and a flexible tube 53. The flexible tube 53 is connected to the nozzle 4 and the paint tank 51 respectively. The air pump 52 is connected to the paint tank 51 and is used to pump the paint in the paint tank 51 to the nozzle 4 through the flexible tube 53.

[0057] In this embodiment, the continuity of paint spraying can be ensured by setting up the paint supply component 5.

[0058] In one embodiment of the present invention, the step of "determining the spraying action of the spraying system based on the spraying task" may specifically include:

[0059] When the spraying task is to spray all the inner wall surfaces of the dust collector hopper 10, the spraying system shall perform the following spraying actions:

[0060] Control base 1 to perform circumferential rotation;

[0061] The initial length of the first support member 2 is controlled to be at its maximum length, at which point the top of the first support member 2 is located at the top of the dust collector hopper 10;

[0062] The initial length of the second support member 3 is controlled to be at its maximum length. At this time, the length of the end of the second support member 3 away from the first support member 2 in the horizontal direction from the inner wall of the dust collector hopper 10 is the preset length.

[0063] After each rotation of the base 1, the first support member 2 is controlled to descend by a preset length (i.e., each unit descent length), and the current actual length of the second support member 3 is controlled based on the preset length.

[0064] Control the supply of anti-corrosion coating to nozzle 4;

[0065] The angle between nozzle 4 and the horizontal direction is kept constant according to the preset method.

[0066] In this embodiment, when the spraying task is to spray all the inner walls of the dust collector hopper 10, it is necessary to rotate the spraying from top to bottom. At the same time, in order to ensure uniform spraying, it is necessary to keep the angle between the nozzle 4 and the horizontal direction constant.

[0067] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the dust collector hopper 10 is an inverted square truncated pyramid structure, and both the upper and lower ports of the dust collector hopper 10 are square.

[0068] The step "controlling the current actual length of the second support member 3 based on the preset length" may specifically include:

[0069] The actual length of the second support member 3 is currently controlled by the following formula:

[0070]

[0071] In the formula, y represents the current actual length of the second support member 3, a represents the side length of the upper port, b represents the side length of the lower port, h represents the height of the dust collector hopper 10, x represents the distance that the first support member 2 has decreased compared to its initial length, which is a multiple of the preset length, and c represents the preset length of the nozzle 4 in the horizontal direction from the inner wall of the dust collector hopper 10.

[0072] In this embodiment, by inputting the relevant dimensional information of the dust collector hopper 10 (i.e., a, b, h, x, and c above) into the control program, the length of the second support member 3 can be adjusted in real time, thereby ensuring the uniformity of the spraying. Otherwise, the nozzle 4 will be too close or too far from the inner wall of the dust collector hopper 10, both of which are detrimental to ensuring the uniformity of the spraying.

[0073] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the dust collector hopper 10 is an inverted square truncated pyramid structure, and both the upper and lower ports of the dust collector hopper 10 are square.

[0074] The step "controlling the angle between nozzle 4 and the horizontal direction to remain constant according to the preset method" may specifically include:

[0075] The angle between nozzle 4 and the horizontal direction is controlled by the following formula:

[0076]

[0077] In the formula, θ is the angle between the nozzle 4 and the horizontal direction, a represents the side length of the upper port, b represents the side length of the lower port, and h represents the height of the dust collector hopper 10.

[0078] In this embodiment, by inputting the relevant dimensional information of the dust collector hopper 10 (i.e., a, b, and h mentioned above) into the control program, the angle between the nozzle 4 and the horizontal direction can be adjusted in real time, thereby ensuring the uniformity of the spraying. Otherwise, the closest distance between the nozzle 4 outlet and the inner wall of the dust collector hopper 10 will change, which is not conducive to ensuring the uniformity of the spraying.

[0079] In one embodiment of the present invention, the step of "determining the spraying action of the spraying system based on the spraying task" may specifically include:

[0080] When the spraying task is to spray the inner wall surface of the dust collector hopper 10, the spraying system shall perform the following spraying actions:

[0081] Based on the range of the inner wall surface of the target, control the range of rotation angle of base 1;

[0082] Based on the height of the target inner wall, control the current actual length of the first support member 2 and the second support member 3;

[0083] Control the supply of anti-corrosion coating to nozzle 4;

[0084] The angle between nozzle 4 and the horizontal direction is kept constant according to the preset method.

[0085] In this embodiment, when the spraying task is to spray the inner wall of the dust collector hopper 10, the nozzle 4 needs to be controlled at the target height and the rotation angle range of the base 1 needs to be controlled to achieve rotational spraying of the inner wall. At the same time, in order to ensure uniform spraying, the angle between the nozzle 4 and the horizontal direction needs to be kept constant.

[0086] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the dust collector hopper 10 is an inverted square truncated pyramid structure, and both the upper and lower ports of the dust collector hopper 10 are square.

[0087] The step "controlling the current actual length of the first support member 2 and the second support member 3 based on the height of the target inner wall" may specifically include:

[0088] Based on the height of the target inner wall, control the current actual length of the first support member 2;

[0089] The current actual length of the second support member 3 is controlled by the following formula:

[0090]

[0091] In the formula, y represents the current actual length of the second support member 3, a represents the side length of the upper port, b represents the side length of the lower port, h represents the height of the dust collector hopper 10, x represents the difference between the current actual length and the initial length of the first support member 2, and c represents the preset length of the nozzle 4 in the horizontal direction from the inner wall of the dust collector hopper 10.

[0092] In this embodiment, by inputting the relevant dimensional information of the dust collector hopper 10 (i.e., a, b, h, x, and c above) into the control program, the length of the second support member 3 can be adjusted in real time, thereby ensuring the uniformity of the spraying. Otherwise, the nozzle 4 will be too close or too far from the inner wall of the dust collector hopper 10, both of which are detrimental to ensuring the uniformity of the spraying.

[0093] like Figure 3 and Figure 4 As shown, in one embodiment of the present invention, the dust collector hopper 10 is an inverted square truncated pyramid structure, and both the upper and lower ports of the dust collector hopper 10 are square.

[0094] The step "controlling the angle between nozzle 4 and the horizontal direction to remain constant according to the preset method" may specifically include:

[0095] The angle between nozzle 4 and the horizontal direction is controlled by the following formula:

[0096]

[0097] In the formula, θ is the angle between the nozzle 4 and the horizontal direction, a represents the side length of the upper port, b represents the side length of the lower port, and h represents the height of the dust collector hopper 10.

[0098] In this embodiment, by inputting the relevant dimensional information of the dust collector hopper 10 (i.e., a, b, and h mentioned above) into the control program, the angle between the nozzle 4 and the horizontal direction can be adjusted in real time, thereby ensuring the uniformity of the spraying. Otherwise, the closest distance between the nozzle 4 outlet and the inner wall of the dust collector hopper 10 will change, which is not conducive to ensuring the uniformity of the spraying.

[0099] The foregoing has described specific embodiments of the invention. Other embodiments are within the scope of the appended claims.

Furthermore, the processes depicted in the drawings do not necessarily require the specific or sequential order shown to achieve the desired results.
