Description

Technical Field

[0001] This utility model relates to the field of equipment spraying technology, specifically an environmentally friendly continuous anti-corrosion coating equipment. Background Technology

[0002] In modern industrial production, metal pipelines are widely used in petroleum, natural gas, chemical, construction, and water conservancy industries. Because pipelines operate in complex environments for extended periods, their surfaces are prone to oxidation, rust, or chemical corrosion, leading to shortened pipeline lifespan, reduced transport efficiency, and even safety accidents such as leaks and explosions. Therefore, applying efficient and environmentally friendly anti-corrosion coatings to the inner and outer walls of pipelines is a crucial step in ensuring the safe operation of industrial systems.

[0003] Existing spraying equipment mostly uses fixed nozzles or manual hand-held spray guns, which makes it difficult to effectively remove adhering substances from the inner wall. Incomplete dust removal will lead to a decrease in coating adhesion, resulting in local peeling, bubbles, or cracks, which seriously affects the anti-corrosion effect. At the same time, existing environmentally friendly spraying equipment mostly uses rigid supports or fixed spray bars, which are difficult to adapt to pipes with different inner diameters. Although some equipment is adjustable, the operation is relatively cumbersome and cannot meet the needs of rapid adaptation to diverse pipe diameters in mass production.

[0004] In summary, developing an environmentally friendly continuous anti-corrosion coating equipment that can address the complex working conditions of iron pipe inner walls and solve problems such as dust accumulation and insufficient pipe diameter adaptation is a technological direction that urgently needs to be broken through in the current industrial anti-corrosion field.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-4 As shown, this utility model provides a technical solution: an environmentally friendly continuous anti-corrosion coating equipment, including a fixed plate 1, a drive motor 101 and an infusion set 102; A screw 103 is connected to the rear end of the drive motor 101. An internally threaded disc 104 is sleeved on the outside of the screw 103. A transmission tube 201 is installed at the front end of the fixed disc 1. The transmission tube 201 is connected to the drive motor 101 through the inside of the fixed disc 1. A collar 203 is sleeved on the outside of the transmission tube 201. Two sets of connecting rods 204 are fixedly connected to the outer wall of the collar 203. Movable rods 205 are inserted inside the two sets of connecting rods 204. A cleaning brush 207 is fixedly installed at one end of the movable rod 205. Three sets of connecting seats 209 are fixedly mounted on the outer walls of the fixed disk 1 and the internal threaded disk 104 respectively. The three sets of connecting seats 209 connected to the outer wall of the fixed disk 1 are respectively connected to a first support frame 211 through a rotating shaft 210. A first movable frame 212 is movably inserted inside the three sets of first support frames 211. A second support frame 3 is respectively connected to the three sets of connecting seats 209 connected to the outer wall of the internal threaded disk 104 through a rotating shaft 210. A second movable frame 301 is movably inserted inside the three sets of second support frames 3. Movable grooves 214 are opened on the outer walls of the three sets of first support frames 211 and first movable frames 212.

[0019] Based on the overall structure of the device, by automatically removing dust and deposits from the inner wall, problems such as poor coating adhesion, easy peeling, and blistering caused by incomplete pretreatment are solved. This can form a more uniform and dense anti-corrosion layer, thereby greatly improving the anti-corrosion effect, extending the service life of the pipeline, and reducing safety risks. At the same time, by adjusting the structure, it can quickly adapt to pipelines of different diameters, solving the pain point of cumbersome adjustment of traditional equipment, realizing rapid switching of diverse pipe diameters, and greatly improving overall production efficiency.

[0020] like Figure 2 As shown, the outer wall of the internal threaded disc 104 is fixedly welded with three sets of throttles 105 in an array, and the outer wall of the three sets of throttles 105 is provided with anti-slip texture.

[0021] By using an internal threaded disc 104 sleeved on the outside of the screw 103, and then welding a throttle 105 onto the outer wall of the internal threaded disc 104, the position of the internal threaded disc 104 on the screw 103 can be adjusted by gripping and rotating the throttle 105.

[0022] like Figure 3 As shown, a sealing sleeve 2 is provided on the outside of the transmission tube 201. The sealing sleeve 2 is made of rubber and is tightly attached to the outer wall of the fixed plate 1. A liquid supply rod 202 is connected to the front end of the transmission tube 201. A nozzle is installed on the left end of the liquid supply rod 202 and the nozzle is installed in a vertical direction.

[0023] The gap between the fixed plate 1 and the transmission pipe 201 is sealed by installing the sealing sleeve 2. At the same time, a vertical nozzle is installed. When the transmission pipe 201 rotates, it drives the nozzle to rotate and spray the inner wall of the pipe.

[0024] like Figure 3 As shown, multiple slots 206 are equidistantly provided on the outer walls of the two sets of connecting rods 204 and movable rods 205. A first bolt 208 is inserted into the slot 206, and nuts are fitted at both ends of the first bolt 208.

[0025] The movable rod 205 and the connecting rod 204 are connected in series using the first bolt 208, and then fixed with a nut.

[0026] like Figure 1 As shown, the lower ends of the three sets of first movable frames 212 and second movable frames 301 are respectively connected to a set of pulleys 213.

[0027] By installing pulley 213, it can serve as a contact support and a means of movement, making it easier to pull outwards manually.

[0028] like Figure 4As shown, multiple sets of fixing slots 215 are equidistantly provided on the outer walls of the first support frame 211, the first movable frame 212, the second support frame 3, and the second movable frame 301. Movable slots 214 are provided on the outer walls of the three sets of first support frames 211 and first movable frames 212. The second movable frame 301 passes through the inside of the movable slot 214. The second movable frame 301 and the first movable frame 212 are connected by a second bolt 216. Nuts are fitted on both ends of the second bolt 216 for fixing.

[0029] By inserting the second movable frame 301 into the interior of the movable slot 214, and then connecting the first movable frame 212 and the second movable frame 301 with the second bolt 216 and nut, the structure can be fixed when adjusted according to the inner diameter of the pipe, thus providing overall support and stability.

[0030] Working Principle: This equipment can continuously apply anti-corrosion coating to the inner wall of pipes. During use, first adjust the structure according to the inner diameter of the pipes to be coated in batches. During adjustment, the second bolt 216 and the nuts at both ends can be removed. When coating larger pipe inner diameters, pull the second movable frame 301 outward from the second support frame 3, and pull the first movable frame 212 outward from the inside of the first support frame 211. When coating smaller inner diameters, push it inward. Then ensure that the pulleys 213 are on the same horizontal line. For finer adjustments, hold the handle 105 and rotate the internal threaded disc 104. When the threads inside the internal threaded disc 104 intersect with the threads on the outer wall of the screw 103, it will move the internal threaded disc 104 on the screw 103. This allows for finer adjustments. After adjustment, use the second bolt 216 and nuts to secure it. Next, according to the inner diameter of the pipe, pull the movable rod 205 out from inside the connecting rod 204 or push it inward to ensure that the cleaning brush 207 is in contact with the inner wall of the pipe, and then fix it with the first bolt 208. Before the preparation work, it is also necessary to connect the wiring of the drive motor 101 and connect the spraying pipe to the infusion set 102. Then, tie the two pull ropes on both sides to the screw 103, and then pull the equipment to the front end of the pipe. Then, turn on the power and run it. When running, the drive motor 101 will drive the transmission pipe 201 to rotate, which in turn drives the infusion rod 202 to rotate to perform the spraying work. These are the existing technical solutions and work. The principle will not be described in detail here. This utility model adds a cleaning function. When the transmission tube 201 rotates, it also drives the collar 203 to rotate. When the collar 203 rotates, it drives the connecting rod 204 and the movable rod 205 to rotate, which in turn drives the cleaning brush 207 to clean the inner wall of the pipe. In this way, when the staff pulls the equipment out, the cleaning brush 207 will first clean the inner wall at high speed before spraying. During the cleaning, the dust will float inside the pipe. With the help of the blower, the dust is blown out from one end of the pipe to the other end. In this way, the dust is minimized from affecting the spraying effect.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
