Description

Technical Field

[0001] This invention belongs to the field of coating spraying technology, and specifically relates to a device for uniformly spraying anti-fouling and anti-corrosion coatings. Background Technology

[0002] A coating is a solid, continuous film obtained by applying paint. It is a thin layer applied to a substrate such as metal, fabric, or plastic for purposes such as protection, insulation, decoration, and corrosion prevention. Paints can be gaseous, liquid, or solid, and the type and state of the paint are usually determined by the substrate to be sprayed.

[0003] To extend the service life of metal building components (such as steel pipes, channel steel, fasteners, etc.), an anti-fouling and anti-corrosion coating needs to be sprayed on the surface of the components after production. This coating isolates the components from oxygen and moisture in the air, reducing their corrosive effects. High-pressure airless sprayers are widely used for spraying metal building components due to their high efficiency, uniform and dense coating, economic and environmental friendliness, and wide applicability. However, existing high-pressure airless sprayers lack a mixing function for the coating during the material suction process. This can cause the coating to separate under the enormous negative pressure after entering the suction pipe, severely affecting the spraying quality. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and reasonably designed device for uniformly spraying anti-fouling and anti-corrosion coatings in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A device for uniformly spraying an anti-fouling and anti-corrosion coating includes a support assembly, a drive mechanism mounted on the support assembly, a pump mechanism mounted below the drive mechanism, a pumping end connected to a pumping pipe, a rotating shaft inside the pumping pipe, and connecting rings rotatably fitted at both ends of the rotating shaft. The outer walls of the connecting rings are fixedly connected to the inner walls of the pumping pipe via fixing rods. Multiple impellers are fixedly mounted in the middle section of the rotating shaft, with a gap between the circumference of the impellers and the inner wall of the pumping pipe. An expansion groove is formed on the inner wall of the pumping pipe on the circumference of the middle section of the rotating shaft. A filter structure is installed at the end of the pumping pipe away from the pump mechanism, and an anti-clogging mechanism is installed inside the filter structure. One end of the anti-clogging mechanism is fixedly connected to the end of the rotating shaft.

[0007] As a further optimization of the present invention, the support component includes a U-shaped bottom bracket, with the same axle rotatably connected to both ends of the bottom bracket, and movable wheels fixedly connected to both ends of the axle. A support steel pipe is welded and fixed to the upper surface of the middle section of the bottom bracket, and push rods are fixedly connected to the upper surfaces of both ends of the bottom bracket.

[0008] As a further optimization of the present invention, the driving mechanism includes a pneumatic motor fixedly installed on the top of the supporting steel pipe, a pressure regulating valve fixedly installed on the push rod below the pneumatic motor, an air pipe connector fixedly connected to the air inlet end of the pressure regulating valve, a connector switch installed on the air pipe connector, an exhaust pipe connected to the exhaust end of the pressure regulating valve, and an exhaust pipe connected to the end of the exhaust pipe away from the pressure regulating valve connected to the air inlet end of the pneumatic motor.

[0009] As a further optimization of the present invention, a pressure gauge is installed on one side of the pressure regulating valve, an air filter is installed at the connection between the exhaust pipe and the exhaust end of the pressure regulating valve, and a silencer is installed at the exhaust end of the pneumatic motor.

[0010] As a further optimization of the present invention, the pumping mechanism includes a plunger pump disposed below the pneumatic motor. The pumping end of the plunger pump is detachably connected to a connecting pipe through a first connector. A check valve is also installed on the pumping end of the plunger pump. The plunger rod of the plunger pump is connected to the output end of the pneumatic motor. A mounting seat is fixedly sleeved on the periphery of the middle section of the plunger pump. A connecting rod is fixedly connected to the bottom wall of the pneumatic motor. The bottom end of the connecting rod passes through the mounting seat and is fixedly connected to the mounting seat with a nut.

[0011] As a further optimization of the present invention, a pressure storage filter is installed at the discharge end of the plunger pump, a pressure relief valve is installed on one side of the pressure storage filter, a high-pressure hose is connected to the outer wall of the pressure relief valve, and a spray gun connector is fixedly installed at the end of the high-pressure hose away from the pressure relief valve.

[0012] As a further optimization of the present invention, the material extraction tube has an L-shaped structure, and a second connector is fixedly connected to the material extraction tube. An annular anti-detachment groove is provided on the second connector. One end of the material extraction tube is fixedly connected to the connecting material tube through the second connector. An expansion groove is provided on the inner wall of the material extraction tube on the periphery of the middle section of the rotating shaft. The filter structure includes a filter cover fixedly connected to the other end of the material extraction tube. An annularly distributed filter hole is provided on the side wall of the filter cover.

[0013] As a further optimization of the present invention, the connection end of the filter cover and the material extraction tube is integrally formed with a flange, and a plurality of annularly distributed arc-shaped holes are opened on the flange. A connecting plate is formed between two adjacent arc-shaped holes. The connecting plate and the filter holes are staggered. A sliding sleeve is slidably fitted on the periphery of the filter cover. A sliding groove is opened on the sliding sleeve. The sliding sleeve is slidably connected to the connecting plate through the sliding groove. An elastic sealing gasket that is aligned with the filter holes is fixedly connected to the inner wall of the sliding sleeve.

[0014] As a further optimization of the present invention, the anti-clogging mechanism includes a transmission rod disposed inside the filter cover, one end of the transmission rod being fixedly connected to the end of the rotating shaft, the other end of the transmission rod being rotatably connected to the bottom wall of the filter cover, a connecting sleeve being fixedly sleeved in the middle section of the transmission rod, and a brush being fixedly installed on the outer surface of the connecting sleeve.

[0015] The beneficial effects of this invention are as follows:

[0016] Because the suction pipe is connected to a rotating shaft, and multiple impellers are installed in the middle section of the shaft, when the paint flows in the suction pipe, it can drive the impellers to rotate. The rotation of the impellers can not only stir the paint entering the suction pipe and prevent the paint from separating due to negative pressure, but also the rotating impellers can rub against the paint to generate heat, which raises the temperature of the paint, increases the fluidity of the paint, and makes the subsequent spraying of the paint more uniform.

[0017] The filter cover is equipped with a transmission rod that is fixedly connected to the end of the rotating shaft. A brush is installed in the middle section of the transmission rod through a connecting sleeve. When the impeller drives the rotating shaft to rotate, the transmission rod can drive the brush to rotate synchronously. The rotating brush cleans the filter holes on the filter cover, so as to avoid the filter holes from being blocked and affecting the coating feeding.

[0018] As the paint in the external paint bucket is drawn out, the paint level in the paint bucket gradually decreases. When the paint level inside the external paint bucket is too low, causing some filter holes to be exposed to air, the user can slide the sliding sleeve downwards. The elastic sealing gasket will adhere to the filter holes under negative pressure, sealing the filter holes exposed above the paint. This will minimize the risk of air entering the plunger pump when the paint is drawn out, which could lead to uneven paint spraying. Attached Figure Description

Detailed Implementation

[0030] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0031] like Figure 1 - Figure 2 As shown, a device for uniformly spraying an anti-fouling and anti-corrosion coating includes a U-shaped bottom support 101. The bottom support 101 has a common axle 102 rotatably connected to both ends. Movable wheels 103 are fixedly connected to both ends of the axle 102. A supporting steel pipe 104 is welded and fixed to the upper surface of the middle section of the bottom support 101. Push rods 105 are fixedly connected to the upper surfaces of both ends of the bottom support 101. The bottom support 101, in conjunction with the movable wheels 103, supports the supporting steel pipe 104 to prevent it from tipping over. When movement is required, the user can press down on the push rods 105 to detach the lower surface of the bottom support 101 from the ground, and then push the movable wheels 103 along the ground using the push rods 105 to move the device.

[0032] like Figure 1 - Figure 2As shown, a pneumatic motor 201 is fixedly installed on the top of the supporting steel pipe 104, and a pressure regulating valve 202 is provided below the pneumatic motor 201. The pressure regulating valve 202 is fixedly installed on the push rod 105, and an air pipe connector 203 is fixedly connected to the air inlet end of the pressure regulating valve 202. The pressure regulating valve 202 can be connected to the air supply pipe of an external air pump through the air pipe connector 203.

[0033] A connector switch 204 is installed on the air pipe connector 203. An exhaust pipe 207 is connected to the exhaust end of the pressure regulating valve 202. The end of the exhaust pipe 207 away from the pressure regulating valve 202 is connected to the air inlet end of the pneumatic motor 201, which delivers high-pressure gas to the pneumatic motor 201 and drives the pneumatic motor 201 to rotate. The pressure regulating valve 202 can precisely adjust the air pressure entering the pneumatic motor 201 as needed to ensure the stable operation of the pneumatic motor.

[0034] A pressure gauge 205 is installed on one side of the pressure regulating valve 202, allowing users to adjust the air pressure according to the pressure value displayed on the pressure gauge 205. An air filter 206 is installed at the connection between the exhaust pipe 207 and the exhaust end of the pressure regulating valve 202. Before entering the exhaust pipe 207, the high-pressure gas must pass through the air filter 206 to filter dust and impurities in the high-pressure gas, minimizing the risk of dust and impurities entering the pneumatic motor 201 and causing damage to it. A silencer 208 is installed at the exhaust end of the pneumatic motor 201, which can significantly reduce the noise when the exhaust gas is discharged from the exhaust end of the pneumatic motor 201, thereby reducing noise pollution.

[0035] like Figure 3 As shown, a plunger pump 301 is mounted on the pneumatic motor 201. A mounting base 306 is fixedly sleeved around the middle section of the plunger pump 301. A connecting rod 307 is fixedly connected to the bottom wall of the pneumatic motor 201. The bottom end of the connecting rod 307 passes through the mounting base 306 and is fixedly connected to the mounting base 306 with a nut, thereby mounting the plunger pump 301 to the bottom of the pneumatic motor 201. The material extraction end of the plunger pump 301 is detachably connected to a connecting pipe 305 through a first connector 302. The connecting pipe 305 is a flexible hose. A check valve 304 is installed on the material extraction end of the plunger pump 301. The plunger rod 303 of the plunger pump 301 is connected to the output end of the pneumatic motor 201 (the pneumatic motor 201 drives the plunger pump 301 to pump material through a transmission structure, which is existing technology and will not be described in detail here). When the pneumatic motor 201 is started, it can drive the piston to move back and forth in the plunger pump 301 through the plunger rod 303, and use the negative pressure to cooperate with the check valve 304 to extract the paint.

[0036] A pressure storage filter 401 is installed at the discharge end of the plunger pump 301. A pressure relief valve 402 is installed on one side of the pressure storage filter 401. A high-pressure hose 403 is connected to the outer wall of the pressure relief valve 402. After the paint is drawn into the plunger pump 301, it cannot flow back due to the obstruction of the check valve 304. When the pneumatic motor 201 drives the plunger rod 303 to push the piston down, the paint enters the pressure storage filter 401 under pressure. After the pressure storage filter 401 filters the impurities in the paint, the paint is then forced into the high-pressure hose 403. A spray gun connector 404 is fixedly installed at the end of the high-pressure hose 403 away from the pressure relief valve 402. A spray gun for spraying paint can be connected through the spray gun connector 404. When the pressure of the paint in the high-pressure hose 403 reaches the set pressure, the spray gun can be opened to spray the paint at high speed through the nozzle of the spray gun for rapid spraying of the building construction parts.

[0037] like Figures 4-5 As shown, a suction pipe 501 is provided at the end of the connecting pipe 305 away from the plunger pump 301. The suction pipe 501 is used to extract paint from the external paint bucket. A second connector 502 is fixedly connected to the suction pipe 501. An annular anti-detachment groove 503 is provided on the second connector 502. One end of the suction pipe 501 is inserted into the connecting pipe 305 through the second connector 502. A clamp is tied around the end of the connecting pipe 305. The second connector 502 is fixedly connected to the connecting pipe 305 by the clamp and the annular anti-detachment groove 503. The design of the annular anti-detachment groove 503 can greatly increase the stability of the connection between the connecting pipe 305 and the second connector 502, and prevent the connecting pipe 305 and the second connector 502 from slipping off due to excessive pressure when extracting paint.

[0038] The extraction tube 501 has an L-shaped structure. The connecting end of the extraction tube 501 can be suspended on the wall of the outer paint bucket through the bend of the extraction tube 501. The end of the extraction tube 501 away from the second connector 502 is fixedly connected to a filter cover 504. The side wall of the filter cover 504 has multiple annularly distributed filter holes 505. The paint is initially filtered through the filter holes 505, while preventing the hardened paint from entering the extraction tube 501 and causing blockage inside the extraction tube 501.

[0039] like Figure 6 , Figure 9 and Figure 10As shown, the connection end between the filter cover 504 and the feed tube 501 is integrally formed with a flange 506. The flange 506 has multiple annularly distributed arc-shaped holes 601. A connecting plate 602 is formed between two adjacent arc-shaped holes 601. The connecting plate 602 is staggered with the filter hole 505. A sliding sleeve 603 is slidably sleeved on the periphery of the filter cover 504. A sliding groove 604 is provided on the sliding sleeve 603. The sliding sleeve 603 is slidably connected to the connecting plate 602 through the sliding groove 604. An elastic sealing gasket 606 is fixedly connected to the inner wall of the sliding sleeve 603 and is aligned with the filter hole 505. An anti-slip ring 605 is provided at the opening end of the sliding groove 604 to prevent the sliding sleeve 603 from slipping out of the arc-shaped hole 601.

[0040] When the paint level inside the external paint bucket is too low, causing some of the filter holes 505 to be exposed to air, the user can slide the sliding sleeve 603 downwards and use the elastic sealing gasket 606 to seal the filter holes 505 under negative pressure, thus sealing the filter holes 505 exposed above the paint. This helps to prevent air from entering the plunger pump 301 when the paint is being drawn, which could lead to uneven paint spraying.

[0041] like Figure 5 , Figure 7 and Figure 8 As shown, a rotating shaft 701 is installed inside the extraction pipe 501. Connecting rings 702 are rotatably sleeved at both ends of the rotating shaft 701. The outer wall of the connecting rings 702 is fixedly connected to the inner wall of the extraction pipe 501 through a fixing rod 703. Multiple impellers 704 are installed inside the extraction pipe 501. A fixing hole 705 is opened in the center of the impeller 704. The impeller 704 is fixedly sleeved on the middle section of the rotating shaft 701 through the fixing hole 705. A gap is left between the periphery of the impeller 704 and the inner wall of the extraction pipe 501. When the paint flows in the extraction pipe 501, the paint flow can drive the impeller 704 to rotate. The rotation of the impeller 704 can not only stir the paint entering the extraction pipe 501 and prevent the paint from separating due to negative pressure, but also generate friction between the paint and the rotating impeller 704. The friction generates heat energy, which raises the temperature of the paint, increases the fluidity of the paint, and makes the subsequent spraying of the paint more uniform.

[0042] like Figure 5 As shown, an expansion groove 706 is provided on the inner wall of the material extraction pipe 501 on the periphery of the middle section of the rotating shaft 701. The expansion groove 706 is provided to increase the inner diameter of the material extraction pipe 501 at the position where the impeller 704 is installed, so as to ensure that the coating can be stably supplied through the material extraction pipe 501 and avoid the coating from being blocked when it flows through the rotating shaft 701 and the impeller 704.

[0043] like Figure 7As shown, a transmission rod 801 is provided inside the filter cover 504. One end of the transmission rod 801 is fixed to the end of the rotating shaft 701, and the other end of the transmission rod 801 is rotatably connected to the bottom wall of the filter cover 504. A connecting sleeve 802 is fixedly sleeved in the middle section of the transmission rod 801. A brush 803 is fixedly installed on the outer surface of the connecting sleeve 802. When the impeller 704 drives the rotating shaft 701 to rotate, the transmission rod 801 can drive the brush 803 installed on the connecting sleeve 802 to rotate synchronously. The rotating brush 803 cleans the filter holes 505 opened on the filter cover 504, so as to avoid the filter holes 505 from being blocked and affecting the coating feeding problem.

[0044] It should be noted that, in using this anti-fouling and anti-corrosion coating uniform spraying device, firstly, one end of the extraction pipe 501 connected to the filter cover 504 is inserted into the external paint tank. Then, the external high-pressure air pipe is connected to the air pipe connector 203, allowing the high-pressure gas to enter the pressure regulating valve 202 through the air pipe connector 203. After the user adjusts the air pressure using the pressure regulating valve 202, the high-pressure gas is delivered to the pneumatic motor 201 through the exhaust pipe 207, driving the pneumatic motor 201 to work. The pneumatic motor 201 can drive the plunger rod 303 of the plunger pump 301 to push the piston to move back and forth. With the help of the check valve 304 installed at the bottom of the plunger pump 301, the external... Paint in the paint bucket is drawn into the plunger pump 301. When the pneumatic motor 201 drives the plunger rod 303 to push the piston down, the paint enters the pressure storage filter 401 under pressure. After the pressure storage filter 401 filters the impurities in the paint, the paint is then forced into the high-pressure hose 403. A spray gun connector 404 is fixedly installed at the end of the high-pressure hose 403 away from the pressure relief valve 402. A spray gun for spraying paint can be connected through the spray gun connector 404. When the paint pressure in the high-pressure hose 403 reaches the set pressure, the spray gun can be opened, and the paint can be sprayed out at high speed through the nozzle of the spray gun for rapid spraying of building construction parts.

[0045] Because a rotating shaft 701 is rotatably connected inside the extraction pipe 501, and multiple impellers 704 are installed in the middle section of the rotating shaft 701, and an expansion groove 706 is opened on the inner wall of the extraction pipe 501 around the rotating shaft 701, when the paint flows in the extraction pipe 501, it can drive the impellers 704 to rotate. The rotation of the impellers 704 can not only stir the paint entering the extraction pipe 501 and prevent the paint from separating due to negative pressure, but also the rotating impellers 704 can rub against the paint to generate heat energy, which raises the temperature of the paint, increases the fluidity of the paint, and makes the subsequent spraying of the paint more uniform.

[0046] A transmission rod 801 is installed inside the filter cover 504. A brush 803 is installed in the middle section of the transmission rod 801 through a connecting sleeve 802. When the impeller 704 drives the rotating shaft 701 to rotate, the transmission rod 801 can drive the brush 803 to rotate synchronously. The rotating brush 803 cleans the filter holes 505 opened on the filter cover 504, so as to avoid clogging of the filter holes 505 and affecting the coating feeding problem.

[0047] As the paint in the external paint bucket is drawn out, the paint level in the paint bucket gradually decreases. When the paint level inside the external paint bucket is too low, causing some filter holes 505 to be exposed to air, the user can slide the sliding sleeve 603 downwards. The elastic sealing gasket 606 will adhere to the filter holes 505 under negative pressure, sealing the filter holes 505 exposed above the paint. This will help prevent air from entering the plunger pump 301 when the paint is drawn out, thus avoiding uneven paint spraying.

[0048] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
