Description

Technical Field

[0001] The utility model belongs to the technical field of flame retardant storage, and particularly relates to a flame retardant storage device. Background Art

[0002] In the chemical industry, the storage and management of flame retardants are crucial aspects. As a special additive that can delay or prevent the combustion of materials, flame retardants are widely used in multiple fields such as plastics, textiles, and coatings. However, during storage, flame retardants often face a severe challenge, namely the precipitation and stratification phenomenon. Since flame retardants usually contain multiple components, these components are prone to physical or chemical changes under the influence of environmental factors such as long-term static state, temperature, and humidity changes, resulting in component separation, forming precipitation and supernatant. This precipitation and stratification not only affect the performance stability of the flame retardant but may also lead to a decrease in the flame retardant effect during use and even pose safety hazards.

However, although the existing mechanical stirring methods can directly act on the flame retardant, limited by the design and position of the stirrer, it is often difficult to achieve a comprehensive stirring effect, and there are problems of uneven stirring and low efficiency.

The tank opening 2 is drivingly connected to a main shaft 4. A support frame 11 is connected to the side of the main shaft 4. A frame stirrer 5 is connected to the main shaft 4 and the support frame 11. Scraper plates 51 are arranged on the frame stirrer 5 back to back in the front and rear with the main shaft 4 as the axis of symmetry. The cross section of the scraper plate 51 is triangular. The main shaft 4 is drivingly connected to a transmission shaft 7 through a first transmission assembly 6. The transmission shaft 7 is drivingly connected to an output shaft 9 through a second transmission assembly 8. A paddle 10 is installed on the output shaft 9. The first transmission assembly 6 is composed of an outer housing 61, a first helical gear 62 and a second helical gear 63. The second transmission assembly 8 is composed of an outer housing 81, a third helical gear 82 and a fourth helical gear 83. By using the first transmission assembly 6 and the second transmission assembly 8, the compound movement of revolution and rotation of the paddle 10 is realized, making the stirring more uniform and efficient, and effectively avoiding the precipitation and stratification phenomenon of the flame retardant during storage; through continuous and uniform stirring, the uniform distribution of the flame retardant in the storage tank is maintained, improving the overall performance and use effect of the flame retardant. The outer housing 61 and the first helical gear 62 are both installed on the main shaft 4. The first helical gear 62 is meshed with the second helical gears 63 arranged oppositely on both sides. The second helical gears 63 are installed on the transmission shaft 7. Through the design of the helical gear structure, the power of the main shaft 4 can be stably transmitted to the transmission shaft 7. The outer housing 81 and the fourth helical gear 83 are both installed on the transmission shaft 7. The fourth helical gear 83 is meshed with the third helical gear 82. The third helical gear 82 is installed on the output shaft 9. Through the design of the helical gear structure, the power of the transmission shaft 7 can be stably transmitted to the output shaft 9. The output shaft 9 is rotationally clamped on the support frame 11. The support frame 11 can provide support for the output shaft 9 to ensure the stability of the rotation of the output shaft 9. The number of the paddles 10 is multiple, and the axis of the paddle 10 is parallel to the axis of the main shaft 4. The axes of the storage tank 1 and the main shaft 4 are collinear. The compound movement of revolution and rotation realized by the multiple paddles 10 makes the stirring more uniform and efficient, and effectively avoids the precipitation and stratification phenomenon of the flame retardant during storage. The first helical gear 62 and the second helical gears 63 are both installed inside the outer housing 61. The third helical gear 82 and the fourth helical gears 83 are both installed inside the outer housing 81. A dynamic sealing structure is arranged between the outer housing 61 and the main shaft 4 and the transmission shaft 7. A dynamic sealing structure is arranged between the outer housing 81 and the transmission shaft 7 and the output shaft 9. The dynamic sealing structure, combined with the isolation and protection of the outer housing 61 and the outer housing 81, can make the helical gears stably mesh and transmit power. The output shaft 9 is a hollow circular tube structure. The hollow circular tube structure of the output shaft 9 has a light self-weight, can effectively optimize the dynamic balance, and reduce the power consumption of the reduction motor 3.

[0034] The working principle of this technical solution is as follows: Before releasing the flame retardant stored in the storage tank 1, start the reduction motor 3. When the reduction motor 3 drives the main shaft 4 to rotate, the main shaft 4 drives the first transmission component 6 and the frame stirrer 5 to rotate. When the first helical gear 62 installed on the main shaft 4 rotates, it meshes with and drives the second helical gear 63 to rotate self - rotatably. The second helical gear 63 drives the transmission shaft 7 to rotate. The rotating transmission shaft 7 drives the fourth helical gear 83 to rotate. The fourth helical gear 83 meshes with and drives the third helical gear 82, so that the third helical gear 82 drives the output shaft 9 to rotate. The blades 10 rotate driven by the output shaft 9, causing the flame retardant in the storage tank 1 to flow in the axial direction of the storage tank 1. Since the blades 10 rotate around the axis of the storage tank 1 while rotating self - rotatably, the stirring effect of the flame retardant in the storage tank 1 can be further improved.
