Description

Technical Field

[0001] This utility model relates to the field of corrosion-resistant coating spraying technology, and in particular to a spraying equipment for fiberglass corrosion-resistant coatings. Background Technology

[0002] Baghouse dust collectors are common industrial waste gas purification devices. They filter and purify harmful exhaust gases by passing them through filter bags, effectively removing larger particulate impurities. Baghouse dust collectors have a large filtration capacity, simple structure, and are easy to maintain, thus they are widely used.

[0003] Industrial waste gases, such as the exhaust gas from optical fiber preforms, contain highly corrosive gases such as hydrogen chloride, sulfur dioxide, chlorine, and sulfuric acid mist. They also tend to be quite humid. Therefore, when these gases flow through a baghouse dust collector, they can easily cause severe corrosion to the metal components. To improve the lifespan of baghouse dust collectors and similar equipment while controlling manufacturing costs, fiberglass linings are often added to the surfaces of ordinary metal components that come into direct contact with the corrosive gases. This prevents the exhaust gas from directly contacting the metal components and causing severe corrosion.

[0004] To further improve the corrosion resistance of the lining, a corrosion-resistant coating is applied to the surface of the fiberglass lining that is in direct contact with the exhaust gas using a coating spraying device. The most important step is applying the corrosion-resistant coating to the lining on the inner wall of the intake pipe. Existing spraying equipment uses multiple nozzles arranged in a ring to simultaneously spray the lining on the pipe wall to improve efficiency. However, due to variations in the volume of exhaust gas being purified and the different diameters of the intake pipes in different exhaust gas purification devices, the distance between the nozzles and the inner wall of the pipe changes when spraying pipes of different diameters. This results in variations in the coating thickness applied to the lining surface per unit time, making it difficult to control the thickness of the corrosion-resistant layer and potentially leading to substandard thickness and reduced coating quality.

[0005] To solve the above problems, there is an urgent need for a spraying equipment for fiberglass corrosion-resistant coatings. Utility Model Content

[0006] The purpose of this utility model is to provide a fiberglass corrosion-resistant coating spraying equipment to solve the problem mentioned in the background art that the existing corrosion-resistant coating spraying equipment has difficulty controlling the coating thickness of the inner wall lining of pipes with different diameters, which easily leads to the coating thickness of the corrosion-resistant layer not meeting the standard and thus reducing the quality of the spraying process.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fiberglass corrosion-resistant coating spraying device, comprising a base, a clamping assembly for clamping and fixing the pipe fitting to be sprayed connected to the top of the base, two hydraulic cylinders symmetrically connected to the top of the base, a lifting plate fixedly connected between the output ends of the two hydraulic cylinders, a straight pipe fixedly connected to the bottom of the lifting plate through a connecting plate, the top end of the straight pipe penetrating the connecting plate and connected to a flexible feed pipe, the bottom end of the straight pipe connected to a distribution pipe, multiple flexible and retractable discharge pipes connected in a ring at equal angles on the outer circumference of the distribution pipe, multiple horizontal pipes connected in a ring at equal angles at the ends of the multiple discharge pipes away from the distribution pipe, nozzles connected to the ends of the multiple horizontal pipes away from the distribution pipe, multiple moving assemblies connected in a ring at equal angles on the outer circumference of the distribution pipe, and the multiple horizontal pipes respectively connected to the multiple moving assemblies;

[0008] The moving component is used to move the horizontal tube along the direction of approaching or moving away from the distributing tube.

[0009] Preferably, a sealing protective shell is fixedly sleeved on the outer circumferential surface of the distributing pipe, and the ends of the plurality of horizontal pipes away from the distributing pipe penetrate through the outer wall of the sealing protective shell. A retractable protective cover is fixedly connected between the outer circumferential surface of the horizontal pipe and the outer wall of the sealing protective shell. The advantage of this arrangement is that, by using the sealing protective shell in conjunction with the retractable protective cover, the moving component can be covered and protected without affecting the movement of the nozzle along the axis of the horizontal pipe, thus preventing the coating material from adhering to the moving component during the spraying process and ensuring that the moving component can work normally for a long time.

[0010] Preferably, the sealed protective shell includes a shell and a cover. The cover is fixedly connected to the top of the shell by bolts, and a sealing ring is clamped between the cover and the shell. The advantage of this arrangement is that the cover can be installed on the top of the shell or removed from the top of the shell by turning the bolts, which facilitates the disassembly, installation and maintenance of the moving components and improves the convenience and practicality of the device.

[0011] Preferably, the moving component includes a moving mechanism and a driving mechanism connected to the outer wall of the distributing pipe, the horizontal pipe is connected to the moving mechanism, and the driving mechanism is used to drive the horizontal pipe to move in a direction closer to or away from the distributing pipe through the moving mechanism.

[0012] Preferably, the moving mechanism includes two limiting plates symmetrically fixedly connected to the outer wall of the dispensing pipe. Two limiting grooves are symmetrically opened on the adjacent sides of the two limiting plates. A moving plate is slidably connected between the two limiting grooves. Two elastic elements are symmetrically fixedly connected between the side of the moving plate and the inner wall of the two limiting grooves near the dispensing pipe. The moving plate is connected to a driving mechanism, which drives the moving plate to move along the limiting grooves. The advantage of this arrangement is that by limiting the moving plate through the limiting grooves and elastic elements, the moving plate can be moved stably and reliably. This ensures that the distance between the nozzle and the inner lining of the metal pipe to be coated can be accurately and reliably adjusted according to the diameter of the metal pipe to be coated. This allows for precise and reliable control of the thickness of the anti-corrosion layer sprayed on the inner lining of the metal pipe to be coated, improving the reliability of the coating equipment.

[0013] Preferably, the driving mechanism includes an electric push rod fixedly connected to the outer surface of the dispensing pipe. A fixed block is fixedly connected to the output end of the electric push rod. A first hinge rod is hinged between the fixed block and the outer wall of the dispensing pipe. A second hinge rod is fixedly connected between the fixed block and the top of the moving plate. The advantage of this arrangement is that the fixed block can be moved up and down by the electric push rod, and the first hinge rod, the second hinge rod, and the elastic element can stably drive the moving plate to move, ensuring that the distance adjustment operation between the nozzle and the inner lining layer of the inner wall of the metal pipe to be coated can be performed reliably and accurately.

[0014] In summary, the technical effects and advantages of this utility model are as follows:

[0015] 1. In this utility model, the moving component drives the horizontal tube to move along the direction of approaching or moving away from the distributing tube. This allows for precise and reliable adjustment of the distance between the nozzle and the inner lining of the metal pipe to be coated, based on the pipe diameter. This enables precise and reliable control of the thickness of the anti-corrosion layer sprayed on the inner lining of the metal pipe, thereby improving the reliability of the coating equipment.

[0016] 2. In this utility model, by setting a sealed protective shell in conjunction with a retractable protective cover, the moving component can be covered and protected without affecting the movement of the nozzle along the axis of the horizontal tube, so as to prevent the coating material from adhering to the moving component during the spraying process and ensure that the moving component can work normally for a long time.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please refer to Figures 1-5The fiberglass corrosion-resistant coating spraying equipment shown includes a base 1. The top of the base 1 is connected to a clamping assembly 2 for clamping and fixing the pipe fitting to be sprayed. Two hydraulic cylinders 3 are symmetrically connected to the top of the base 1. A lifting plate 31 is fixedly connected between the output ends of the two hydraulic cylinders 3. A straight pipe 4 is fixedly connected to the bottom of the lifting plate 31 through a connecting plate. The top end of the straight pipe 4 passes through the connecting plate and is connected to a flexible feed pipe 5. The bottom end of the straight pipe 4 is connected to a distribution pipe 6. Multiple flexible and retractable discharge pipes 7 are connected in a ring at equal angles on the outer circumference of the distribution pipe 6. Multiple horizontal pipes 71 are connected in a ring at equal angles at the ends of the multiple discharge pipes 7 away from the distribution pipe 6. Each of the multiple horizontal pipes 71 is connected to a nozzle 72 at the ends of the multiple horizontal pipes 71 away from the distribution pipe 6. Multiple moving assemblies 8 are connected in a ring at equal angles on the outer circumference of the distribution pipe 6. The multiple horizontal pipes 71 are respectively connected to the multiple moving assemblies 8.

[0026] The moving component 8 is used to move the horizontal tube 71 along the direction of approaching or moving away from the distributing tube 6;

[0027] The clamping assembly 2 includes two cylinders 21 that are symmetrically fixed to the top of the base 1. Two clamping plates 22 are symmetrically fixed to the output ends of the two cylinders 21. Two arc-shaped clamping grooves are symmetrically opened on the sides of the two clamping plates 22 that are close to each other. When the two cylinders 21 are activated, they push the two clamping plates 22 closer to each other until the two clamping grooves are pressed tightly against the outer wall of the metal pipe to be sprayed. In this way, the metal pipe to be sprayed can be firmly clamped, ensuring that the subsequent anti-corrosion layer spraying process can be carried out smoothly and reliably.

[0028] The feed pipe 5 is connected to an external liquid pump, which delivers the coating into the feed pipe 5.

[0029] refer to Figures 1-4 A sealing protective shell 9 is fixedly sleeved on the outer circumferential surface of the distribution pipe 6. One end of multiple horizontal pipes 71 away from the distribution pipe 6 penetrates the outer wall of the sealing protective shell 9. A retractable protective cover 10 is fixedly connected between the outer circumferential surface of the horizontal pipes 71 and the outer wall of the sealing protective shell 9.

[0030] Specifically, by using the sealed protective shell 9 in conjunction with the retractable protective cover 10, the moving component 8 can be covered and protected without affecting the movement of the nozzle 72 along the axis of the horizontal tube 71, thus preventing the coating material from adhering to the moving component 8 during the spraying process and ensuring that the moving component 8 can work normally for a long time.

[0031] refer to Figures 2-4 The sealed protective shell 9 includes a shell and a cover 91. The cover 91 is fixedly connected to the top of the shell by bolts, and a sealing ring is clamped between the cover 91 and the shell.

[0032] Specifically, the cover 91 can be installed on the top of the housing or removed from the top of the housing by tightening the bolts, which facilitates the disassembly, installation and maintenance of the movable component 8, and improves the convenience and practicality of the equipment.

[0033] refer to Figures 1-4 The moving component 8 includes a moving mechanism 81 and a driving mechanism 82 connected to the outer wall of the distributing pipe 6. The horizontal pipe 71 is connected to the moving mechanism 81. The driving mechanism 82 is used to drive the horizontal pipe 71 to move in a direction closer to or away from the distributing pipe 6 through the moving mechanism 81.

[0034] refer to Figures 3-5 The moving mechanism 81 includes two limiting plates 811 symmetrically fixedly connected to the outer wall of the distributing pipe 6. Two limiting grooves 812 are symmetrically opened on the side of the two limiting plates 811 that are close to each other. A moving plate 813 is slidably connected between the two limiting grooves 812. Two elastic members 814 are symmetrically fixedly connected between the side of the moving plate 813 and the inner wall of the two limiting grooves 812 that are close to the distributing pipe 6. The moving plate 813 is connected to the driving mechanism 82, which is used to drive the moving plate 813 to move along the limiting grooves 812.

[0035] Specifically, by limiting the moving plate 813 through the limiting groove 812 and the elastic element 814, it can be ensured that the moving plate 813 moves stably and reliably. This ensures that the distance between the nozzle 72 and the inner lining of the metal pipe to be sprayed can be adjusted accurately and reliably according to the diameter of the metal pipe to be sprayed. This allows for precise and reliable control of the thickness of the anti-corrosion layer sprayed on the inner lining of the metal pipe to be sprayed, thereby improving the reliability of the spraying equipment.

[0036] refer to Figures 2-5 The drive mechanism 82 includes an electric push rod 821 fixedly connected to the outer side of the distribution pipe 6. A fixed block 822 is fixedly connected to the output end of the electric push rod 821. A first hinge rod 823 is hinged between the fixed block 822 and the outer side wall of the distribution pipe 6. A second hinge rod 824 is fixedly connected between the fixed block 822 and the top of the moving plate 813.

[0037] Specifically, the electric push rod 821 drives the fixed block 822 to move up and down, and in conjunction with the first hinge rod 823, the second hinge rod 824 and the elastic element 814, the moving plate 813 can be moved stably, ensuring that the distance adjustment operation between the nozzle 72 and the inner lining layer of the metal pipe to be sprayed can be carried out reliably and accurately.

[0038] Working principle: The metal pipe to be sprayed is placed vertically between the two clamping plates 22 and directly below the material distribution pipe 6. Then, the two cylinders 21 push the two clamping plates 22 closer to each other until the two clamping grooves are pressed tightly against the outer wall of the metal pipe to be sprayed, thus firmly clamping the metal pipe to be sprayed.

[0039] Depending on the diameter of the metal pipe to be coated, the electric push rod 821 is activated to move the fixed block 822 up and down. In conjunction with the first hinge rod 823, the second hinge rod 824, and the elastic element 814, the moving plate 813 can be stably moved. In this way, the moving plate 813 will move the nozzle 72 towards or away from the dispensing pipe 6, thereby accurately and reliably adjusting the distance between the nozzle 72 and the inner lining of the metal pipe to be coated. This allows for precise and reliable control of the thickness of the anti-corrosion layer sprayed on the inner lining of the metal pipe to be coated, improving the reliability of the coating equipment.

[0040] Next, the hydraulic cylinder 3 is started, and the lifting plate 31 drives the material distribution pipe 6 to be inserted downward at a uniform speed into the top of the metal pipe to be sprayed, so that the nozzle 72 sprays the anti-corrosion coating evenly on the surface of the inner lining layer of the inner wall of the metal pipe to be sprayed.

[0041] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
