[0002] Fire retardant coating, also known as flame retardant coating, is a kind of non-combustible or flame retardant building structure protection material. Fire retardant coating is divided into two categories: expansion and non-expansion. Its fire protection principle is mainly due to the special properties of fire retardant coating, which can delay the flame temperature from being transmitted to the protected substrate. In addition, fire retardant coating will decompose some inert gases when heated, thereby delaying the flame burning speed.

[0003] When using fire retardant coating, the preparation process required is as follows: the fire retardant coating needs to be mixed and stirred with a diluent to reduce its viscosity. It can be sprayed out with an air gun, and the protective material can be sprayed over a large area by spraying.

[0004] The existing stirring device for preparing fire retardant coating has the following disadvantages: it is difficult to clean the barrel wall after the fire retardant coating and the diluent are mixed, and the stirring device is not suitable for coating containers of different sizes.

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] like Figure 1-Figure 5 As shown, a stirring device for preparing fire retardant coating comprises a lower bracket 2 and an upper bracket 5, wherein a slidable upper bracket 5 is mounted on the lower bracket 2, a variable speed motor 8 is mounted on one end of the top of the upper bracket 5 by bolts, a coupling 9 is mounted on the operating end of the variable speed motor 8, and a stirring device is fixed on the other end of the coupling 9;

[0025] The stirring device comprises a main shaft 10 , a connecting plate 11 and a stirring frame 15 . The connecting plate 11 is fixed parallel to the main shaft 10 , and slidable stirring frames 15 are installed at both ends of the connecting plate 11 .

[0026] like Figure 1 , Figure 2 , Figure 5 As shown, the lower end of the lower bracket 2 is fixed to the upper end of the base 1 by bolts, a step is provided on the side of the upper end of the lower bracket 2, a threaded hole 4 is provided at the center of the step, and a limiting groove 3 for mounting the lower end of the upper bracket 5 is provided at the middle position of the upper end of the lower bracket 2. The limiting groove 3 is rectangular, and the internal dimensions of the limiting groove 3 are the same as the external dimensions of the upper bracket 5. The lower bracket 2 and the upper bracket 5 form a sliding structure.

[0027] Exemplarily, by sliding the upper bracket 5 inside the limit groove 3, the height of the combination of the lower bracket 2 and the upper bracket 5 is changed, and the height of the stirring device is adjusted, so that paint buckets of different heights can be placed under the stirring device. The function of adjusting the stirring device can be used to more conveniently stir paint buckets of different heights.

[0028] like Figure 1 , Figure 2 , Figure 5 As shown, another set of steps is provided at the other end of the top of the upper bracket 5, a bearing is installed at the center position of the step, a threaded rod 6 is installed inside the bearing, one end of the threaded rod 6 is installed inside the threaded hole 4, and a handwheel 7 is welded to the top of the threaded rod 6.

[0029] Exemplarily, by rotating the handwheel 7, the threaded rod 6 can be rotated inside the bearing, and at the same time, the threaded rod 6 can be rotated inside the threaded hole 4. Since the rotation of the upper bracket 5 is restricted, the upper bracket 5 can only slide inside the limit groove 3 through the threaded hole 4, thereby changing the distance between the upper bracket 5 and the lower bracket 2.

[0030] like Figure 3 , Figure 5 As shown, the variable speed motor 8 and the coupling 9 are connected by bolts, and the other end of the coupling 9 is fixedly mounted with a main shaft 10.

[0031] For example, the speed of the variable speed motor 8 can be controlled, and the rotation speed of the main shaft 10 connected through the coupling 9 can be adjusted, so that the speed of the stirring device can be changed, and the difference in speed can be used to enable the stirring device to achieve other functions, such as cleaning the inner wall of the barrel.

[0032] like Figure 4 , Figure 5 As shown, two groups of limiting holes 12 are arranged side by side at both ends of the connecting plate 11, and the connecting plate 11 is provided with four groups of grooves 13, and a group of nuts 14 are movably installed inside each group of grooves 13, and the center of the nut 14 and the center of the limiting hole 12 are on the same horizontal plane. The cross section of the stirring frame 15 is triangular, and two groups of connecting rods 16 are fixed side by side at the upper and lower ends of the stirring frame 15, and the two groups of connecting rods 16 are respectively one group with threads and the other group with smooth circles, and the connecting rods 16 are installed inside the limiting holes 12. One group of threaded connecting rods 16 and the nut 14 are threadedly connected, and the connecting rods 16 and the connecting plate 11 form a sliding structure.

[0033] For example, according to the size of the inner wall diameter of the paint holding bucket, the nut 14 installed on the connecting plate 11 can be rotated, and the stirring frame 15 can be pulled at the same time, so that the threaded connecting rod 16 can be rotated inside the corresponding nut 14, and then the connecting rod 16 can be moved inside the limiting hole 12, thereby changing the distance between the connecting plate 11 and the stirring frame 15, so that the two groups of stirring frames 15 can be placed inside the paint holding bucket, and when one group of nuts 14 falls off or other situations occur, the stirring frame 15 can be inverted to reverse the positions of the upper and lower groups of connecting rods 16 set on the side of the stirring frame 15, so that the threaded connecting rod 16 can be installed inside the nut 14 on the other side, so that the device can continue to be used.

[0034] It should be noted that the two groups of connecting rods 16 are symmetrically arranged, and the spacing between adjacent connecting rods 16 is the same as the spacing between adjacent limiting holes 12 .

[0035] In the above-mentioned implementation process, the distance between the two groups of stirring racks 15 can be adjusted so that the tip of the stirring rack 15 is close to the inside of the containing barrel. After the speed-changing motor 8 is decelerated, the main shaft 10 rotates slowly, and then the connecting plate 11 rotates slowly, so that the stirring racks 15 connected at both ends of the connecting plate 11 rotate slowly, and the inner wall of the containing barrel is scratched, and the paint sticking to the inner wall of the containing barrel needs to be removed.

[0036] Working principle: First, according to the different sizes of fire retardant paint containers, by rotating the nut 14 installed on the connecting plate 11, and pulling the stirring frame 15 at the same time, the threaded connecting rod 16 is rotated inside the corresponding nut 14, and then the two groups of connecting rods 16 are moved inside the limiting hole 12, thereby changing the distance between the connecting plate 11 and the stirring frame 15, so that the spacing between the two groups of stirring frames 15 can be adjusted, so as to achieve the purpose of placing the two groups inside the paint holding bucket, and then the threaded rod 6 can be rotated inside the bearing by rotating the hand wheel 7, and the threaded rod 6 can be rotated inside the threaded hole 4 at the same time, and because the rotation of the upper bracket 5 is restricted, the upper bracket 5 can only pass Slide inside the limit groove 3 through the threaded hole 4, so as to change the distance between the upper bracket 5 and the lower bracket 2, leaving enough height to place the container such as a paint bucket or other barrel-shaped container. After placing the container containing the fire retardant coating and the thinner on the upper end of the base 1, the stirring device is lowered by rotating the hand wheel 7, so that the stirring frame 15 falls into the interior of the container and the bottom end of the stirring frame 15 does not collide with the bottom of the container. After completion, the speed of the main shaft 10 connected by the coupling 9 is connected by the speed-changing motor 8, and then the two sets of stirring frames 15 are driven to rotate with the help of the connecting plate 11, so as to achieve the mixing of the fire retardant coating and the thinner, and complete the preparation of the fire retardant coating. After the stirring is completed, the height of the upper bracket 5 is adjusted to take out the container. When the fire retardant coating is prepared in the container, the distance between the two sets of stirring racks 15 can be adjusted to make the tip of the stirring rack 15 close to the inside of the barrel. After the speed change motor 8 is decelerated, the main shaft 10 rotates slowly, and then the connecting plate 11 rotates slowly, so that the stirring racks 15 connected at both ends of the connecting plate 11 rotate slowly, and the inner wall of the barrel is scratched to clean the coating stuck on the inner wall of the barrel, so as to avoid the accumulation of coating inside the container and affect the quality of the next fire retardant coating preparation.
