Description

Technical Field

[0001] This utility model relates to the technical field of fire-retardant coating mixing equipment, and in particular to a fire-retardant coating production and processing equipment. Background Technology

[0002] Fire-retardant coatings are a special type of coating product that works by being evenly applied to the surface of flammable materials. In the event of a fire, this coating significantly improves the material's fire resistance, effectively slows the spread of flames, and can even prevent combustion for a certain period. Therefore, coatings with fire-retardant properties can be called both fire-retardant and flame-retardant coatings.

[0003] In the production process of fire-retardant coatings, the mixing stage is crucial and indispensable. Typically, mixing devices are used during coating production to ensure the thorough mixing of various materials, thereby guaranteeing the performance and quality of the coating.

[0004] However, given the high viscosity and strong adhesion of fire-retardant coatings, some coating residue often remains after mixing. This residue adheres to the mixing components, container walls, and discharge pipes of the mixing equipment, leading to incomplete discharge. This not only wastes materials and increases production costs but also negatively impacts the mixing quality of subsequent batches of coating, disrupting normal production processes.

[0005] In view of this, we have developed a new type of fire-retardant coating production and processing equipment, which aims to effectively solve the problems of large residue and material waste caused by the strong adhesion of existing fire-retardant materials. Utility Model Content

[0035] like Figure 1-5 As shown, this utility model provides a fireproof coating production and processing equipment, including: a mixing component 1, a cleaning component 2, and a conveying component 3.

[0036] The mixing assembly 1 includes a mixing tank 10. The mixing tank 10 can be made of 304 or 316 stainless steel as the inner wall material. Its surface is smooth and does not easily adhere to coatings. At the same time, stainless steel has good corrosion resistance and can adapt to the chemical environment in the production process of fireproof coatings. The inner wall of the stainless steel should be finely polished to achieve a surface roughness of Ra0.8 or less, further reducing material residue. A motor 11 is connected to the upper middle part of the mixing tank 10. The lower end of the motor 11 passes through the top plate of the mixing tank 10 and is connected to a mixing shaft 12. Several evenly distributed mixing blades 13 are connected to the side wall of the mixing shaft 12. Several horizontal scrapers 14 are connected to the bottom of the mixing shaft 12. A vertical scraper 15 is connected to the outer end of each scraper 14. The scraper 15 should be made of wear-resistant and corrosion-resistant materials such as polyurethane or rubber. In use, by starting motor 11, the stirring shaft 12 is rotated. The stirring shaft 12 simultaneously drives the stirring blade 13 and the shovel 14 to rotate. The stirring blade 13 thoroughly stirs the fireproof coating. The shovel 14 is used to lift the coating deposited at the bottom of the mixing tank 10 to improve the mixing quality. The shovel 14 drives the scraper 15 to rotate, so that the scraper 15 scrapes the coating adhering to the inner wall of the mixing tank 10, continuously scraping off the coating adhering to the inner wall and reducing the adhesion of the coating.

[0037] The cleaning component 2 is used to clean the paint residue inside the mixing tank 10, and the conveying component 3 is used for loading and unloading materials into the mixing tank 10.

[0038] In one embodiment, all shovels 14 are triangular in structure with their inclined surfaces facing upwards. The lower surface of the shovel 14 is in close contact with the inner bottom of the mixing tank 10, allowing the shovel 14 to scrape away the coating deposited at the bottom of the mixing tank 10. The outer wall of the scraper 15 is in close contact with the inner wall of the mixing tank 10, allowing the scraper 15 to scrape away the coating adhering to the inner wall of the mixing tank 10.

[0039] In one embodiment, the cleaning component 2 includes an inner ring 20, a middle ring 21, and an outer ring 22, which are nested together and share the same center. The inner ring 20 is fitted onto the stirring shaft 12. A frame 23 connects the inner ring 20 and the middle ring 21. The frame 23 has a hollow portion 24 in the middle, which matches the stirring blade 13. The hollow portion of the inner ring 20 is connected to the hollow portion 24 to prevent the inner ring 20 from being interfered with by the stirring blade 13 when it descends. The middle ring 21 is connected to the outer ring 22. The outer wall of the outer ring 22 has a groove 28 that matches the scraper 15. A lifter 25 is provided at the upper end of the middle ring 21 to control the up and down movement of the middle ring 21. In use, the lifting device 25 pushes the middle ring 21 down, which in turn lowers the frame 23, outer ring 22, and inner ring 20. This causes the outer ring 22 to scrape off the paint adhering to the inner wall of the mixing tank 10. Simultaneously, the groove 28 on the outer ring 22 scrapes off the paint adhering to the surface of the scraper 15. The frame 23, through its perforated portion 24, contacts the side wall of the mixing blade 13, scraping off the paint adhering to the side wall of the mixing blade 13. This structure facilitates quick cleaning of residual paint inside the mixing tank 10, simplifying cleaning, reducing material waste, and avoiding the problem of large amounts of residual material at the discharge.

[0040] In one embodiment, the lifting device 25 includes a mounting frame 250. An electric push rod 251 is mounted on the upper end of the mounting frame 250. A U-shaped guide rod 252 is connected to the upper end of the electric push rod 251. Both sides of the lower end of the U-shaped guide rod 252 are connected to the middle ring 21. The U-shaped guide rod 252 passes through the top plate of the mixing tank 10 and is slidably connected to the mixing tank 10. In use, the electric push rod 251 retracts, causing the U-shaped guide rod 252 to descend, which in turn pushes the middle ring 21 downward, completing the cleaning operation.

[0041] In one embodiment, the upper surface of the middle ring 21 is provided with an annular groove 26, and sliders 27 are provided on opposite sides inside the annular groove 26. The upper end of the sliders 27 is connected to the U-shaped guide rod 252. Since the slot 28 of the outer ring 22 is always connected to the scraper 15, and at the same time the frame 23 is aligned with the stirring blade 13, the outer ring 22, middle ring 21, inner ring 20 and frame 23 all rotate with the scraper 15. During the rotation of the outer ring 22, the sliders 27 slide relative to the groove 26, but remain stationary with the U-shaped guide rod 252, so that the U-shaped guide rod 252 is always connected to the middle ring 21, which facilitates the control of the lifting and lowering of the middle ring 21 by the U-shaped guide rod 252.

[0042] In one embodiment, the conveying assembly 3 includes a feed pipe 30 and a discharge pipe 31 respectively disposed on the upper and lower sides of the mixing tank 10, and both the feed pipe 30 and the discharge pipe 31 are inclined. A motor 33 is installed at one end of both the feed pipe 30 and the discharge pipe 31. The output end of the motor 33 is connected to a rotating shaft 34, and a spiral blade 35 is connected to the outer surface of the rotating shaft 34. During feeding, the coating is put into the feed port of the feed pipe 30, and the motor 33 is started. The motor 33 drives the rotating shaft 34 to rotate, and the rotating shaft 34 controls the spiral blade 35 to rotate, pushing the coating to move within the feed pipe 30 and finally into the mixing tank 10. The principle of discharge is the same. This structure can adapt to the conveying of high-viscosity, easily clogged materials. It can continuously and stably deliver fire-retardant coatings into the mixing equipment, reducing the labor intensity and error of manual feeding.

[0043] In one embodiment, spiral heating blocks 36 are fitted onto the outer walls of both the feed pipe 30 and the discharge pipe 31. The heating blocks 36 can be heated using resistance wire or electromagnetic induction heating. A protective shell 37, made of insulating material, is provided at the outer end of the spiral heating block 36. Depending on the properties of the coating, heating via the spiral heating blocks 36 can reduce the viscosity of the fire-retardant coating and improve its fluidity. This structure helps improve the efficiency of feeding and discharging, reducing the problem of blockage at the feed or discharge port.

[0044] The specific usage process of this utility model is as follows:

[0045] Start the spiral heating block 36 to heat the feed pipe 30, add the fire retardant coating into the feed port of the feed pipe 30, start the motor 2 33, the motor 2 33 drives the rotating shaft 34 to rotate, the rotating shaft 34 drives the spiral blade 35 to rotate, the spiral blade 35 pushes the fire retardant coating to move inside the feed pipe 30 and enter the mixing box 10;

[0046] After all the fire retardant coatings have entered the mixing tank 10, the motor 11 is started. The motor 11 drives the mixing shaft 12 to rotate, and the mixing shaft 12 drives the mixing blade 13 to rotate. The mixing blade 13 mixes and stirs the fire retardant material and the fire retardant coating. At the same time, the mixing shaft 12 drives the shovel 14 to rotate, so that the shovel 14 shovels the fire retardant coating deposited at the bottom of the mixing tank 10. The shovel 14 drives the scraper 15 to rotate, so that the scraper 15 continuously scrapes off the fire retardant coating adhering to the inner wall of the mixing tank 10. After the mixture is evenly mixed, the fire retardant coating is discharged through the discharge pipe 31. The discharge pipe 31 is also conveyed by the heating block 36 and the spiral blade 35.

[0047] After the fire retardant coating is discharged from the mixing tank 10, the U-shaped guide rod 252 is lowered by the electric push rod 251. The U-shaped guide rod 252 pushes the middle ring 21 to descend. The middle ring 21 drives the inner ring 20, outer ring 22 and frame 23 to descend. The outer ring 22 scrapes off the fire retardant coating adhering to the inner side wall of the mixing tank 10. The frame 23 scrapes off the fire retardant coating adhering to the side wall of the mixing blade 13, so that the fire retardant coating falls into the bottom of the mixing tank 10 and is discharged neatly with the shovel plate 14.

[0048] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
