Description

Technical Field

[0001] The present invention relates to the technical field of waterproof coating application, and in particular to a waterproof coating application device for a sewage treatment plant tank. Background Art

[0002] During the construction of the sewage treatment plant pool, a layer of waterproof coating needs to be sprayed on the inner wall and bottom surface of the pool to ensure the waterproof ability of the inner wall of the sewage treatment plant pool. When spraying, waterproof coating coating equipment is needed instead of manual spraying to improve the spraying effect.

[0003] The existing waterproof coating equipment has the following deficiencies when spraying waterproof coating on the inner wall of the sewage treatment plant pool: before spraying, the dust and impurities on the inner wall surface of the sewage treatment plant pool will affect the adhesion between the material and the inner wall surface, which is not conducive to the adhesion of the coating and the inner wall surface, and reduces the waterproof effect of the sewage treatment plant pool after coating. In addition, after spraying, the waterproof coating dries slowly after being applied to the inner wall of the sewage treatment plant pool, causing the coating sprayed on the vertical inner wall to flow downward, resulting in uneven coating of some coatings, reducing the waterproof effect; at the same time, when spraying the coating, the coating is prone to agglomeration after the temperature drops, and the nozzle is prone to clogging, resulting in uneven spraying.

[0019] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

Therefore, features specified as "first" or "second" may explicitly or implicitly include one or more of the specified features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0021] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the Figure 1 The orientation and position of the sewage treatment plant tank waterproof coating equipment when normally placed are shown only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or component referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside" and "outside" refer to the inside and outside relative to the outline of each component itself.

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0023] The present invention provides a sewage treatment plant tank body waterproof coating equipment, see Figure 1-4, including: a supporting vehicle plate 100, a movable wheel 110 is provided at the bottom thereof, a paint box 200, a power box 300, a paint pump and a supporting frame 500 are provided on the upper surface; a controller 290 is provided on the paint box 200, the controller 290 is electrically connected to the power box 300 and controls the operation of the paint pump; the paint pump includes a paint motor 400, the front end of the paint pump is connected to the diverter head 410, the output end of the paint pump is located in one end of the diverter head 410, the paint pump is connected to the paint box 200 through a delivery pipe 420, the diverter head 410 0 is connected to the first solenoid valve 430 at the upper end through the shunt pipe 411, and the first solenoid valve 430 is connected to the shunt vertical pipe 440 through the connecting pipe 431. A first nozzle 441 is provided on the outer side of the shunt vertical pipe 440, and the shunt vertical pipe 440 is driven to swing horizontally by the swing arm 450; the other end of the shunt head 410 is connected to the connecting hose 510 on the support frame 500 through the second solenoid valve 460, and the lower end of the connecting hose 510 is connected to the shunt horizontal pipe 511, and a second nozzle 512 is provided at the bottom of the shunt horizontal pipe 511.

[0024] The painting equipment, based on a supporting vehicle panel 100, integrates paint storage, delivery, and spraying functions. The paint tank 200 activates the paint motor 400 via the controller 290. The paint is then pumped through the delivery pipe 420 to the paint pump for pressurization. The paint is then distributed through the diverter head 410 to two paths: the first path: via the first solenoid valve 430, the connecting pipe 431, the diverter vertical pipe 440, and the first spray head 441. This, combined with the horizontal swing of the swing arm 450, expands the longitudinal spraying range. The second path: via the second solenoid valve 460, the connecting hose 510, the diverter horizontal pipe 511, and the second spray head 512, achieving horizontal spraying. During operation, the controller 290 opens and closes the first and second solenoid valves 430, 460 as needed, selecting single- or dual-path spraying mode.

[0025] For example, the reciprocating rotation of the electric motor drives the swing arm 450 to swing back and forth, thereby achieving axial rotation of the diversion standpipe 440.

[0026] Adapt to the coating requirements of different areas of the pool body (such as horizontal pipes for flat surfaces and vertical pipes for corners) to achieve dual-path spraying; swing spraying avoids missing paint, improves coating uniformity, and achieves dynamic coverage; solenoid valves are independently regulated to save paint consumption and complete modular control.

[0027] In one embodiment, see Figure 3 A vacuum cleaner 520 is provided on the top of the support frame 500. The air inlet end of the vacuum cleaner 520 is connected to the exhaust pipe 521, the exhaust pipe 521 is connected to the rear end of the air inlet box 522, the front surface of the air inlet box 522 is provided with an air inlet 523, and a pull-out dust drawer 524 is provided at the bottom. The air outlet end of the vacuum cleaner 520 is connected to the rear end of the heating box 526 through the air outlet pipe 525, and the front surface of the heating box 526 is provided with an air outlet 527.

[0028] The rear end of the air intake box 522 is inclined, and a filter (not shown) is located at the junction between the rear end of the air intake box 522 and the exhaust pipe 521. The filter traps dust at the rear end of the air intake box 522 and conducts the dust downward through the inclined surface into the dust drawer 524. The vacuum cleaner 520 draws dust-laden air from the front end of the air intake box 522 through the exhaust pipe 521. After the dust is collected in the drawer, the clean air is sent to the heating box 526 through the exhaust pipe 525 for heating, and finally discharged as dry hot air through the outlet 527.

[0029] The air after vacuuming is heated and reused, which is energy-saving and efficient, and recycles energy. It pre-treats the pool wall surface to improve the adhesion of the paint, and integrates dust removal and drying.

[0030] Exemplarily, multiple layers of filters (not shown) are provided in the air intake box 522 to intercept dust particles of different sizes.

[0031] Exemplarily, the heating box 526 has a built-in heating wire or a PTC heating module, and the temperature can be controlled at 50-80°C.

[0032] In one embodiment, see Figure 3 Infrared lamps 528 are located in front of the heating box 526 to illuminate the inner wall of the tank to accelerate the drying of the paint. The infrared lamps 528 irradiate the inner wall of the tank in the same direction as the air outlet 527 of the heating box 526, and together they act on the inner wall of the tank, creating a "radiation + convection" dual heating effect with the hot air.

[0033] For example, the infrared lamp 528 uses medium-wave infrared (wavelength 2-4 μm), and the radiation distance is adjustable (0.5-1.5 m).

[0034] Infrared rays directly penetrate the surface of the coating, drying the inside and outside simultaneously, avoiding blistering and accelerating curing; hot air fills the blind spots of infrared irradiation, improves treatment uniformity, and creates a synergistic effect.

[0035] In one embodiment, see Figure 1-2 The support frame 500 is equipped with a lifter 530 at its bottom to adjust its height to accommodate pool walls of varying heights. This eliminates the need for scaffolding, reduces the risk of working at height, and allows for high pool walls. The spray module provides full coverage and precise positioning.

[0036] For example, the lifter 530 is a hydraulic cylinder or an electric push rod, which drives the support frame 500 to rise and fall as a whole. The lifting stroke is set according to the pool depth (e.g., 0-5m), and is equipped with a limit sensor to prevent overload.

[0037] In one embodiment, see Figure 5-7The surface of the paint box 200 is provided with an insulated door panel 210, and the top is provided with a top plate 220. The bottom of the top plate 220 is connected to the discharge hose 230. The upper end of the discharge hose 230 is connected to the conveying pipe 420, and the lower end of the discharge hose 230 is provided with a weighted ball head 231; the motor 240 is installed on the top plate 220, and its output end is connected to the rotating rod 250. The rotating rod 250 is located at the bottom of the top plate 220, and a horizontal support rod 251 and a stirring blade 252 are provided on the outside of the rotating rod 250; the adding hopper 260 is embedded in the top of the paint box 200 for replenishing paint.

[0038] The paint tank 200 rotates via a motor 240 that drives the agitator blades 252. Meanwhile, a weighted ball 231 at the bottom of the discharge hose 230 keeps the nozzle submerged in the paint. This maintains paint uniformity and prevents nozzle clogging. The weighted design ensures continuous discharge.

[0039] Exemplarily, the stirring blade 252 rotates at a speed of 200-500 rpm to prevent the coating from settling.

[0040] Exemplarily, the weighted ball head 231 is made of stainless steel to avoid corrosion.

[0041] In one embodiment, see Figure 7 A spoiler mechanism 270 is provided on the inner wall of the paint box 200. The spoiler mechanism 270 includes sealing plates 271 at the upper and lower ends and a heat conducting plate 272 in the middle, forming a triangular prism structure. A heating tube 273 is fixed inside the triangular prism structure, and the heating tube 273 is controlled by a starter 280 outside the paint box 200. A spoiler 274 is provided on the outer surface of the heat conducting plate 272.

[0042] The flow-disrupting mechanism 270 disrupts the laminar flow through the triangular prism-shaped heat conducting plate 272 and the flow-disrupting plate 274. The heating tube 273 maintains the temperature of the paint to prevent viscosity changes caused by low temperatures. The flow-disrupting plate 274 improves stirring efficiency.

[0043] For example, the power of the heating tube 273 is 1-2 kW, and the temperature control accuracy is ±2°C.

[0044] For example, the spoiler 274 rotates in the opposite direction to the stirring blade 252 to enhance turbulence and prevent spray vibration deviation.

[0045] In one embodiment, the diversion cross pipe 511 is fixed to the edge of the supporting vehicle plate 100 through the raising arm 540 .

[0046] In one embodiment, the first solenoid valve 430 and the second solenoid valve 460 are electrically connected to a sub-controller 550 on the support frame 500 via a control line 470. The sub-controller 550 is centrally controlled by the controller 290. The sub-controller 550 centrally controls the solenoid valves to achieve one-touch switching of spray modes.

[0047] In one embodiment, the dust drawer 524 is a detachable structure for centrally collecting sucked dust and impurities for easy cleaning and maintenance.

[0048] In one embodiment, the stirring blade 252 is spiral or paddle-shaped, so as to enhance the stirring effect of the paint, increase the shear force, and avoid agglomeration.

[0049] In one embodiment, the spoiler 274 has a wavy or zigzag structure, which is used to disrupt the laminar flow state of the paint flow and further break up the paint clusters.

[0050] In one embodiment, the moving wheels 110 are universal wheels, and at least one of the moving wheels 110 is equipped with a braking device, so that the moving wheels 110 can be flexible and stable during construction.

[0051] The present invention provides a method for using a sewage treatment plant tank waterproof coating device, the specific steps of which are as follows: Step 1: The vacuum cleaner 520 uses the exhaust pipe 521 to extract air, and the air is sucked into the air intake box 522 from the air inlet 523 to remove the dust and impurities on the inner wall surface of the sewage pool before painting. The dust and impurities on the inner wall surface of the sewage pool are cleaned before spraying to improve the adhesion between the inner wall surface of the sewage pool and the paint.

[0052] Step 2: The spoiler mechanism 270 heats the heating tube 273, the heat conducting plate 272 conducts heat, and the spoiler 274 performs spoiling, thereby heating the paint inside the paint box 200 and efficiently stirring the paint, thereby improving the fineness of the paint coating, avoiding blockage inside the first nozzle 441 and the second nozzle 512 during paint coating, and improving the uniformity of the coating.

[0053] Step three, the lifter 530 and the support frame 500 are raised and lowered, and adjusted according to the height of the sewage pool wall, and simultaneously drive the diversion vertical pipe 440, the air intake box 522 and the heating box 526 to be raised and lowered, so that the air intake box 522 can clean the dust and impurities on the sewage pool wall at different heights, and the diversion vertical pipe 440 and the heating box 526 can spray the waterproof coating and dry the sewage pool wall at different heights.

[0054] Step 4: Vacuum cleaner 520 and exhaust pipe 525 to discharge the sucked air into the heating box 526 for drying. The dry air is ejected from the air outlet 527 and the inner wall of the sewage pool after painting is dried in conjunction with the heating irradiation of the infrared lamp tube 528, thereby accelerating the drying effect of the waterproof coating and preventing the coating from flowing downwards and causing uneven coating.

[0055] The present invention uses a vacuum cleaner 520 to start working. At this time, the exhaust pipe 521 is used to extract air, and the dust and impurities on the inner wall surface of the sewage pool are sucked into the air intake box 522 from the air inlet 523, and the dust and impurities on the inner wall surface of the sewage pool are cleaned before spraying, thereby solving the problem of poor adhesion between the inner wall surface of the sewage pool and the paint.

[0056] The present invention uses a vacuum cleaner 520 to discharge the inhaled air through an air outlet pipe 525 into a heating box 526 to heat the air, making the air dry and raising the temperature. The dried air is ejected forward from the air outlet 527 and combined with the high-temperature irradiation of the infrared lamp 528, the inner wall of the sewage pool coated with waterproof paint is quickly dried, preventing the paint from flowing downward on the vertical inner wall of the sewage pool, resulting in uneven coating, thereby solving the problem of poor waterproof effect after coating of the sewage treatment plant pool body.

[0057] The present invention uses a motor 240 to drive a rotating rod 250, a horizontal support rod 251 and a stirring blade 252 to stir the paint inside the paint box 200. During the stirring process, heating is performed by a heating tube 273, and heat is conducted through a heat conducting plate 272, so that the temperature of the paint increases. Under the turbulence of the spoiler 274, the paint is stirred more finely, and the paint with increased temperature is not easy to agglomerate, thereby solving the problem that the paint agglomerates easily and becomes blocked inside the nozzle during the spraying process.

[0058] The present invention adopts a paint motor 400 to transport the paint from the delivery pipe 420 to the paint pump for pressurization, and then connects two solenoid valves through the diversion head 410 to allow the paint to evenly enter the diversion vertical pipe 440 and the diversion horizontal pipe 511, and spray out through the first nozzle 441 and the second nozzle 512. The second nozzle 512 sprays waterproof paint on the bottom surface of the sewage pool, while the first nozzle 441 sprays the vertical inner wall of the sewage pool. At the same time, the opening and closing of the two solenoid valves are controlled by the sub-controller 550, and the first nozzle 441 and the second nozzle 512 are independently controlled, and the bottom surface of the sewage pool, the vertical inner wall, or both are selectively sprayed, thereby improving the working effect of the spraying.

[0059] The present invention adopts a lifter 530 at the bottom of the support frame 500 to drive the support frame 500 to be raised and lowered as a whole, so that the diversion vertical pipe 440, the air intake box 522 and the heating box 526 can be raised and lowered, which can produce the effect of cleaning dust and impurities on the walls of sewage pools at different heights, spraying waterproof coatings on the walls of sewage pools at different heights, and drying them.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
