Description

Technical Field

[0001] The utility model relates to the technical field of fire retardant coating processing, in particular to an automatic proportioning fire retardant coating stirring device. Background Art

[0002] Fire retardant coatings are specialized coatings used on combustible substrates to reduce their flammability, slow the spread of fire, and ultimately improve their fire resistance. These coatings are applied to combustible substrates to alter their surface combustion characteristics and slow the spread of fire, or to building components to improve their fire resistance.

[0003] In the production process of fire retardant coatings, after the liquid coating is added, different types of granular additives need to be added to the liquid coating and stirred to improve the performance of the fire retardant coating. Since different granular additives react differently with each other, the granular additives need to be added to the liquid coating at different times to reduce the reaction between different granular additives and achieve the best performance of the coating. The traditional addition method is mostly done by the staff themselves, which not only increases the labor intensity of the staff, but also because the dosage required for each granular additive is different and the addition order is different, the manual addition method is prone to inaccurate addition order and dosage, resulting in inconsistent quality of fire retardant coating production.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Reference Figure 1-7 An automatic mixing device for fire-retardant coatings includes a mixing barrel 1, a first rotary motor 2 mounted at the bottom of the barrel, a rotating shaft 6 disposed within the barrel, and stirring blades mounted on the rotating shaft 6. The output end of the first rotary motor 2 flexibly extends through the bottom of the barrel and connects to the rotating shaft 6. A discharge pipe 3 is disposed at the bottom of the barrel, and a fixed block 4 is mounted at the top of the barrel, with a loading mechanism mounted on the fixed block 4. The rotating shaft 6 and stirring blades stir the coating within the barrel, the discharge pipe 3 discharges the stirred coating from the barrel, and the loading mechanism automatically adds particulate additives to the barrel.

[0026] As a technical optimization solution of the present invention, the feeding mechanism includes a feeding tube 5 and a loading barrel 9. A first slot 7 is provided at the bottom of the fixed block 4, and multiple feeding tubes 5 are evenly installed on the top of the fixed block 4. The feeding tubes 5 extend into the interior of the first slot 7, and a loading barrel 9 is movably installed inside the first slot 7. Different feeding tubes 5 can be filled with different granular additives. The loading barrel 9 can collect and weigh the granular additives added by the feeding tubes 5, completing the precise control of the amount of granular additive added.

[0027] As a technical optimization solution of the present invention, the bottom of the loading barrel 9 is movably connected with a movable block 8, which is movably installed inside the first slot 7. The movable block 8 allows the loading barrel 9 to be converted into different usage states according to different usage requirements.

[0028] As a technical optimization solution of the present invention, a chute 10 is provided at the bottom end of the inner wall on both sides of the first slot 7, and an electric slider 11 is installed on the side of the movable block 8 close to the chute 10. The electric slider 11 is slidably installed inside the chute 10. The sliding of the electric slider 11 in the electric chute 10 allows the movable block 8 to move inside the first slot 7, and the movement of the movable block 8 allows the loading barrel 9 to move to the bottom of the corresponding feeding pipe 5. When the loading barrel 9 is unloading, the movement of the electric slider 11 allows the granular additive inside the loading barrel 9 to be more evenly spread inside the mixing barrel 1, thereby increasing the mixing uniformity of the mixing barrel 1.

[0029] As a technical optimization solution of the present invention, a second rotary motor 14 is embedded in the movable block 8 on the side close to the electric slider 11, and the electric slider 11 is connected to the mounting end of the second rotary motor 14. The second rotary motor 14 drives the movable block 8 to rotate, causing the loading barrel 9 to rotate downward, so that the granular additive inside the loading barrel 9 can be poured into the mixing barrel 1 below, so that the granular additive inside the loading barrel 9 can be smoothly discharged.

[0030] As a technical optimization solution of the present invention, a second slot 16 is provided at the top center of the movable block 8, a pressure sensor 17 is installed at the bottom end of the inner wall of the second slot 16, a spring telescopic rod 13 is slidably installed inside the second slot 16, the end of the spring telescopic rod 13 away from the pressure sensor 17 is connected to the bottom of the loading barrel 9, and the end of the spring telescopic rod 13 close to the pressure sensor 17 is in contact with the pressure sensor 17. As the amount of granular additives inside the loading barrel 9 increases, the loading barrel 9 squeezes the spring telescopic rod 13 downward, and the spring telescopic rod 13 squeezes the pressure sensor 17. The pressure sensor 17 transmits the measured pressure value to the background control system. When the pressure value measured by the pressure sensor 17 reaches a preset value, the feed pipe 5 stops conveying the granular additives. At this time, it means that the granular additives inside the loading barrel 9 have reached the preset amount. This operation method can automatically and accurately control the amount of granular additives added, which increases the convenience of using the device.

[0031] As a technical optimization solution of the present invention, a plurality of support grooves 15 are evenly arranged on the top of the movable block 8. A support rod 12 is slidably installed inside the support groove 15. The end of the support rod 12 away from the movable block 8 is connected to the bottom of the loading barrel 9. The sliding of the support rod 12 in the support groove 15 increases the operating stability of the loading barrel 9 on the movable block 8.

[0032] When the present invention is in use, the electrical equipment on the device is powered by an external power supply through a wire. The electrical equipment in the device is controlled by setting a background control system. The model of the pressure sensor 17 used in the present device is LFC-09A. The stirring form of the stirring barrel 1, the rotating shaft 6 and the stirring blade is an existing mature technology, so it will not be elaborated on in detail. The discharge pipe 3 and the distribution pipe 5 are both controlled by valves. The valve is an existing mature technology, so it will not be elaborated on in detail. One distribution pipe 5 corresponds to one granular additive.

[0033] When the device needs to stir the paint, a preset amount of liquid paint is added to the mixing barrel 1 through the existing liquid paint filling pipe, and then the first rotary motor 2 drives the rotating shaft 6 to rotate to stir the paint inside the mixing barrel 1. When it is necessary to add granular additives to the mixing barrel 1, the sliding of the electric slider 11 in the electric slide 10 causes the movable block 8 to move inside the first slot 7. The movement of the movable block 8 causes the loading barrel 9 to move to the bottom of the corresponding distribution pipe 5. Then, the distribution pipe 5 starts to convey the granular additives, and the granular additives enter the loading barrel 9. As the amount of granular additives inside the loading barrel 9 increases, the loading barrel 9 squeezes the spring telescopic rod 13 downward, and the spring telescopic rod 13 squeezes the pressure sensor 17. The pressure sensor 17 transmits the measured pressure value to the background control system. When the pressure value measured by the pressure sensor 17 reaches the preset value, the distribution pipe 5 stops conveying the granular additives, which indicates that the granular additives inside the loading barrel 9 have reached the preset amount. This operation method can automatically and accurately control the amount of granular additives added, which increases the convenience of using the device.

[0034] After a preset amount of granular additives is added to the loading barrel 9, the second rotating motor 14 drives the movable block 8 to rotate, causing the loading barrel 9 to rotate downward, so that the granular additives inside the loading barrel 9 can be poured into the mixing barrel 1 below. At the same time, the electric slider 11 slides inside the slide 10 at a preset speed. The sliding speed of the electric slider 11 is adapted to the pouring speed of the loading barrel 9. Through this operation method, the granular additives inside the loading barrel 9 can be more evenly sprinkled inside the mixing barrel 1, thereby increasing the stirring uniformity of the mixing barrel 1.

[0035] Then the device adds different granular additives into the interior of the mixing barrel 1 in turn according to the stirring requirements in accordance with the above-mentioned operation method, and finally completes the stirring production of the paint through the stirring of the mixing barrel 1. When the paint is stirred and can be discharged, the paint can be discharged through the discharge pipe 3.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
