Description

Technical Field

[0001] This invention relates to fire-retardant coating production technology, specifically to a production equipment and method for solvent-based fire-retardant coatings. Background Technology

[0002] Fire-retardant coatings are a special type of coating that can increase the fire resistance limit of the coated object for a certain period of time, thereby preventing or delaying the spread of fire. They are widely used in building structures, cables, steel structures and other fields, and are one of the important fire protection products. Fire-retardant coatings need to be mixed with various raw materials and water or solvents during production.

[0003] Chinese patent CN114369383A discloses an environmentally friendly fire-retardant paint coating and its energy-saving production equipment. This environmentally friendly fire-retardant paint coating and its energy-saving production equipment improve the fire-retardant properties of the paint coating by adding appropriate components to it, thereby enhancing the decorative and protective effect of the paint coating on the surface of objects. At the same time, by setting appropriate grinding and dispersing mechanisms in the grinding and dispersing equipment used for paint coating production, the grinding and dispersing effect of the paint coating raw materials is improved, thereby enhancing the energy-saving and environmental protection of the paint coating production process.

[0004] When using existing equipment, after the coating production is completed, the coating needs to be exported to a storage container. Because the coating is easily exposed to air during transportation, the solvent evaporates too quickly, and the oxidation and curing phenomenon is more serious. At the same time, the air remaining in the export pipe may oxidize and adhere to the inner wall of the export pipe, resulting in a decrease in transportation efficiency and easy to cause the production line to stop. Therefore, a production equipment and method for solvent-based fire retardant coatings has been developed. Summary of the Invention

[0005] The purpose of this invention is to provide a production equipment and method for solvent-based fire-retardant coatings to overcome the above-mentioned shortcomings in the prior art.

[0009] The control component includes a positioning block that engages with the tray, a cover plate is fixedly installed at the end of the positioning block, an elastic element is fixedly installed at the end of the cover plate, and a protective plate is fixedly installed at the end of the elastic element.

[0014] An arc-shaped plate is symmetrically fixedly installed at one end of the positioning block, and an arc-shaped groove is opened at the end of the arc-shaped plate. A moving block is slidably installed on the inner wall of the arc-shaped groove.

[0015] A movable block is rotatably mounted on the end of the movable block, and the end of the movable block is fixedly connected to the end of the movable rod.

[0016] A positioning plate is fixedly installed at the end of the positioning block and above the arc-shaped plate. A first driving rod is rotatably installed at the end of the positioning plate, and a second driving rod perpendicular to the first driving rod is rotatably installed at the end of the positioning plate. The outer surface of the first driving rod engages with the outer surface of the second driving rod, and the end of the second driving rod is rotatably connected to the inner wall of the movable block.

[0017] A driving component is fixedly installed at the end of the positioning block, and a transmission belt is provided at the output end of the driving component, with the inner wall of the transmission belt in contact with the outer surface of the first driving rod.

[0018] The sealing assembly includes a locking plate that engages with the inner wall of the extension tube, and a telescopic rod is fixedly installed at the middle position of the end of the locking plate.

[0019] A power ring is rotatably mounted on the end of the locking plate. The inner wall of the power ring has a first annular groove, and the lower end of the power ring has a second annular groove. The inner wall of the second annular groove is slidably connected to the outer surface of the end of the locking plate.

[0020] A limiting plate is fixedly installed at the end of the locking plate, and multiple sets of adjusting plates are evenly rotatably installed at the end of the limiting plate. An adjusting rod is rotatably installed at the end of the adjusting plate, and the end of the adjusting rod away from the adjusting plate is rotatably connected to the inner wall of the first annular groove. An adjusting block is engaged at the end of the adjusting plate.

[0021] A pressing plate is fixedly installed at the end of the telescopic rod, and an inclined plate corresponding to the adjusting block is fixedly installed at the end of the pressing plate. The outer surface of the inclined plate is slidably connected to the outer surface of the end of the adjusting block.

[0022] The end of the extrusion plate is fitted with a tapered plate, and the end of the adjustment plate is rotatably mounted with a snap-fit ​​plate.

[0023] A method for producing solvent-based fire-retardant coatings, using the aforementioned production equipment, includes the following steps:

[0024] S1. The piston block moves to compress the gas inside the positioning block, thereby pushing the protective plate to move until the air inside the positioning block is discharged.

[0026] S3. The inner cavity of the conical plate is equipped with an air bladder, and the outer surface of the air bladder is equipped with rubber or other sealing components. At the same time, the side of the conical plate is provided with holes, so that when the air bladder is squeezed, the air bladder is confined through the holes and tightly adheres to the inner wall of the extension tube. Through the functions of venting and sealing, the accumulation or leakage of coating during the discharge process can be reduced.

[0027] Compared with the prior art, the production equipment and method for solvent-based fire-retardant coatings provided by the present invention have the following beneficial effects:

[0028] By adjusting the components, the coating maintains its fluidity during transportation, reducing coating retention. Combined with the exhaust equipment, air in the pipeline is ensured to be discharged in a timely manner, avoiding poor transportation or blockage caused by air accumulation, thereby improving transportation efficiency and stability.

[0029] The double-layer pipe design effectively isolates the coating from the outside air, and the inner wall of the extension pipe is protected by multiple sealing components, reducing the contact area between the coating and the air, thereby significantly reducing the risk of oxidation and curing, and ensuring the fluidity and stability of the coating.

[0030] By using both control and sealing components for dual protection, solvent leakage is effectively prevented, and the accumulation and curing of coatings due to solvent evaporation are reduced. The air-isolation design reduces harmful volatile substances in the environment, thus improving the environmental friendliness of the production process. Attached Figure Description

[0046] Example 1:

[0047] Please see Figures 1-10 A production equipment for solvent-based fire retardant coatings includes a transfer pipe 1, an extension pipe 11 slidably installed on the inner wall of the transfer pipe 1, a partition plate 12 rotatably installed on the inner wall of the transfer pipe 1, and a support plate 13 fixedly installed on the outer surface of the extension pipe 11.

[0048] In this design, the connection between the transmission pipe 1 and the extension pipe 11 is provided with a sealing component such as rubber, and the extension pipe 11 can move up and down along the inner wall of the transmission pipe 1.

[0049] The partition plate 12 adjusts its tilt angle according to the actual operating conditions. When it needs to stop, the partition plate 12 and the end of the extension tube 11 are parallel. At the same time, when the extension tube 11 moves upward, it is tightly attached to the partition plate 12 to ensure that the transmission tube 1 is isolated from the outside.

[0050] The support plate 13 is used to support the control component 2, so that the control component 2 is stably attached to the outer surface of the extension tube 11.

[0051] Furthermore, the control component 2 is assembled on the pallet 13 and communicates with the interior of the extension tube 11. The control component 2 discharges air in a timely manner during the material discharge process. The control component 2 includes a positioning block 21 that is snapped into the pallet 13. A cover plate 22 is fixedly installed at the end of the positioning block 21. An elastic element 221 is fixedly installed at the end of the cover plate 22. A protective plate 222 is fixedly installed at the end of the elastic element 221.

[0052] In this embodiment, the end of the positioning block 21 is provided with bolts and other components that have a fixing function. The positioning block 21 is locked to the support plate 13 by bolts. At the same time, a certain gap is reserved between the cover plate 22 and the positioning block 21 so that after the protective plate 222 is separated from the positioning block 21, the air inside the extension tube 11 is discharged.

[0053] The outer surface of the protective plate 222 is provided with sealing components such as rubber, and the elastic element 221 is an elastic component such as a spring. The protective plate 222 is pressed tightly against the end of the positioning block 21 by the elastic element 221.

[0054] Furthermore, a fixing plate 23 is fixedly installed on one side of the positioning block 21, a power component 24 is fixedly installed at the end of the fixing plate 23, a crankshaft 241 is fixedly installed at the output end of the power component 24, and a push rod 242 is rotatably installed on the outer surface of the crankshaft 241. A movable rod 261 is rotatably installed at the end of the push rod 242.

[0055] Specifically, the power component 24 is a device with power output, such as a motor, and is connected to an external control device. When the power component 24 is started, it synchronously drives the crankshaft 241, which is fixedly installed at its output end, to rotate. Since the push rod 242 is rotatably installed on the outer surface of the crankshaft 241, the push rod 242 drives the power rod 28 to reciprocate.

[0056] The end of the movable rod 261 is rotatably connected to the connection between the push rod 242 and the power rod 28. By adjusting the position of the movable rod 261, the movement trajectory of the power rod 28 can be adjusted.

[0057] Furthermore, a piston block 281 is slidably mounted on the inner wall of the positioning block 21, and a power rod 28 is rotatably mounted on the end of the piston block 281. The end of the power rod 28 is rotatably connected to the end of the movable rod 261.

[0058] Specifically, the outer surface of the piston block 281 is provided with sealing components such as rubber. The piston block 281 moves to squeeze the gas inside the positioning block 21, thereby pushing the protective plate 222 to move until the air inside the positioning block 21 is discharged. Then the piston block 281 moves in the opposite direction, and the protective plate 222 is pressed tightly against the end of the positioning block 21 again by the action of the elastic member 221.

[0059] Furthermore, the positioning block 21 is provided with a connecting pipe 29, the end of which penetrates and extends into the inner cavity of the positioning block 21.

[0060] Specifically, a rubber ring and a support rod are fixedly installed in the inner cavity of the connecting pipe 29, and a rubber ball is provided between the rubber ring and the support rod. The piston block 281 drives the rubber ball to fit or separate from the rubber ring and the support rod respectively.

[0061] An inclined baffle is provided in the inner cavity of the extension tube 11 and at the end of the connecting tube 29 to protect the connecting tube 29.

[0062] Furthermore, an arc-shaped plate 25 is symmetrically fixedly installed at one end of the positioning block 21. An arc-shaped groove 251 is formed at the end of the arc-shaped plate 25, and a moving block 252 is slidably installed on the inner wall of the arc-shaped groove 251. A movable block 26 is rotatably installed at the end of the movable block 252, and the end of the movable block 26 is fixedly connected to the end of the movable rod 261.

[0063] Specifically, by adjusting the position of the moving block 252 and simultaneously moving the movable block 26, the position of the movable rod 261 is adjusted, and then the activity state of the piston block 281 is adjusted when the movable rod 261 moves, until it conforms to the current scenario.

[0064] Furthermore, a positioning plate 27 is fixedly installed at the end of the positioning block 21 and above the arc plate 25. A first drive rod 271 is rotatably installed at the end of the positioning plate 27, and a second drive rod 272 perpendicular to the first drive rod 271 is rotatably installed at the end of the positioning plate 27. The outer surface of the first drive rod 271 engages with the outer surface of the second drive rod 272, and the end of the second drive rod 272 is rotatably connected to the inner wall of the movable block 26.

[0065] Specifically, when the first drive rod 271 rotates, it synchronously drives the second drive rod 272, which meshes with its outer surface, to rotate. Since the end of the second drive rod 272 is rotatably connected to the inner wall of the movable block 26, and the outer surface of the second drive rod 272 is spiral, the position of the movable block 26 is adjusted when the second drive rod 272 rotates until the optimal position is reached.

[0066] Furthermore, a drive component 211 is fixedly installed at the end of the positioning block 21, and a transmission belt 212 is provided at the output end of the drive component 211, with the inner wall of the transmission belt 212 in contact with the outer surface of the first drive rod 271.

[0067] Specifically, the drive component 211 is a device with power output, such as a motor, and is connected to an external control device. When the drive component 211 is started, it synchronously drives the transmission belt 212, which is engaged with its output end, to rotate, and drives the first drive rod 271, which is engaged with the inner wall of the transmission belt 212, to rotate.

[0068] Furthermore, the sealing assembly 3, which is assembled in the inner cavity of the extension tube 11, provides multiple barriers between the coating and the outside to prevent the coating from overflowing; the sealing assembly 3 includes a locking plate 31 that engages with the inner wall of the extension tube 11, and a telescopic rod 311 is fixedly installed at the middle position of the end of the locking plate 31.

[0069] In this embodiment, the outer surface of the telescopic rod 311 is fitted with a spring or other elastic component. One end of the spring is connected to the locking plate 31, and the other end is connected to the end of the pressing plate 36, so that after the pressing plate 36 is moved by force, the spring stretches the pressing plate 36 to the initial position.

[0070] Furthermore, a power ring 32 is rotatably mounted on the end of the locking plate 31. The inner wall of the power ring 32 is provided with a first annular groove 321, and the lower end of the power ring 32 is provided with a second annular groove 322. The inner wall of the second annular groove 322 is slidably connected to the outer surface of the end of the locking plate 31.

[0071] Specifically, a motor is fixedly installed at the end of the locking plate 31, and the output end of the motor meshes with the outer surface of the power ring 32, thereby driving the power ring 32 to rotate.

[0072] Furthermore, a limiting plate 33 is fixedly installed at the end of the locking plate 31, and multiple sets of adjusting plates 35 are evenly rotatably installed at the end of the limiting plate 33. An adjusting rod 351 is rotatably installed at the end of the adjusting plate 35. The end of the adjusting rod 351 away from the adjusting plate 35 is rotatably connected to the inner wall of the first annular groove 321. An adjusting block 352 is snapped into the end of the adjusting plate 35.

[0073] Specifically, when the power ring 32 rotates, it works in conjunction with the first annular groove 321 to drive the adjusting rod 351 to move. At the same time, when the adjusting rod 351 moves, it drives the adjusting plate 35 to rotate around the limiting plate 33.

[0074] Furthermore, a pressing plate 36 is fixedly installed at the end of the telescopic rod 311, and an inclined plate 361 corresponding to the adjusting block 352 is fixedly installed at the end of the pressing plate 36. The outer surface of the inclined plate 361 is slidably connected to the outer surface of the end of the adjusting block 352.

[0075] Specifically, when the adjusting plate 35 moves, it drives the adjusting block 352 fixedly installed at its end to move, and when the adjusting block 352 moves, it squeezes the inclined plate 361, thereby driving the squeezing plate 36 to move upward and squeezing the conical plate 37 to move.

[0076] Furthermore, a tapered plate 37 is attached to the end of the extrusion plate 36, and a snap-fit ​​plate 34 is rotatably mounted on the end of the adjustment plate 35.

[0077] Specifically, the inner cavity of the conical plate 37 is provided with an air bladder, and the outer surface of the air bladder is provided with rubber or other sealing components. At the same time, the end of the conical plate 37 is provided with holes so that when the air bladder is squeezed, it fits tightly against the inner wall of the extension tube 11. Through the functions of venting and sealing, the accumulation or leakage of coating during the discharge process can be reduced.

[0078] Example 2:

[0079] A method for producing solvent-based fire-retardant coatings, using the aforementioned production equipment, includes the following steps:

[0080] S1. The piston block 281 moves to squeeze the gas inside the positioning block 21, thereby pushing the protective plate 222 to move until the air inside the positioning block 21 is discharged. Then the piston block 281 moves in the opposite direction, and the protective plate 222 is pressed tightly against the end of the positioning block 21 again under the action of the elastic member 221.

[0081] S2. The positioning block 21 is locked onto the support plate 13 by bolts. At the same time, a certain gap is reserved between the cover plate 22 and the positioning block 21 so that the air inside the extension tube 11 can be discharged after the protective plate 222 is separated from the positioning block 21. The outer surface of the protective plate 222 is provided with rubber, and the elastic element 221 presses the protective plate 222 tightly against the end of the positioning block 21.

[0082] S3. The inner cavity of the conical plate 37 is provided with an airbag, and the outer surface of the airbag is provided with rubber or other sealing components. At the same time, the side of the conical plate 37 is provided with holes, so that when the airbag is squeezed, the airbag is confined through the holes and tightly adhered to the inner wall of the extension tube 11. Through the functions of venting and sealing, the accumulation or leakage of coating during the discharge process can be reduced.

[0083] The control device can be a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.

[0084] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

An adjusting rod (351) is rotatably installed at the end of the adjusting plate (35). The end of the adjusting rod (351) away from the adjusting plate (35) is rotatably connected to the inner wall of the first annular groove (321). An adjusting block (352) is snapped into the end of the adjusting plate (35).

8. The production equipment for solvent-based fire-retardant coatings according to claim 7, characterized in that, A compression plate (36) is fixedly installed at the end of the telescopic rod (311), and an inclined plate (361) corresponding to the adjusting block (352) is fixedly installed at the end of the compression plate (36). The outer surface of the inclined plate (361) is slidably connected to the outer surface of the end of the adjusting block (352).

9. The production equipment for solvent-based fire-retardant coatings according to claim 8, characterized in that, The end of the extrusion plate (36) is fitted with a tapered plate (37), and the end of the adjustment plate (35) is rotatably mounted with a snap-fit ​​plate (34).

10. A method for producing a solvent-based fire-retardant coating, characterized in that, Using the production equipment described in any one of claims 1-9, the production method includes the following steps: S1. The piston block (281) moves to squeeze the gas inside the positioning block (21), thereby pushing the protective plate (222) to move until the air inside the positioning block (21) is discharged. Then the piston block (281) moves in the opposite direction, and the protective plate (222) is pressed against the end of the positioning block (21) again by the action of the elastic member (221). S2. The positioning block (21) is locked onto the support plate (13) by bolts. At the same time, a certain gap is reserved between the cover plate (22) and the positioning block (21) so that the air inside the extension tube (11) can be discharged after the protective plate (222) is separated from the positioning block (21). The outer surface of the protective plate (222) is provided with rubber, and the protective plate (222) is pressed tightly against the end of the positioning block (21) by the elastic element (221). S3. The inner cavity of the conical plate (37) is provided with an air bladder, and the outer surface of the air bladder is provided with rubber. At the same time, the side of the conical plate (37) is provided with holes, so that when the air bladder is squeezed, the air bladder is constrained through the holes and tightly adhered to the inner wall of the extension tube (11). Through the function of venting and sealing, the accumulation or leakage of coating during the discharge process can be reduced.
