Description

Technical Field

[0001] This utility model relates to the field of fire-retardant coating processing technology, specifically to a fire-retardant coating processing raw material mixing equipment. Background Technology

[0002] In the processing of fire-retardant coatings, raw material blending is a crucial step in ensuring coating performance. Currently, raw material blending equipment often faces the problem of raw materials becoming damp and clumping due to improper humidity control during storage when processing powdered raw materials. These clumped powders, once fed into the blending equipment, are difficult to disperse quickly and tend to form localized agglomerates. This not only prolongs blending time and increases equipment energy consumption but also leads to uneven mixing, causing the proportions of various components in the coating to deviate from preset values. Consequently, this affects key indicators such as the film-forming properties and fire resistance limit of the fire-retardant coating, adversely impacting its application effectiveness and safety.

[0003] Patent publication number CN203061124U provides a raw material blending device, including a blending tank, a motor, a reducer, a stirring shaft, and a stirring paddle. The motor is connected to the reducer, the reducer is connected to the stirring shaft, and the stirring shaft is equipped with a stirring paddle. The blending tank has a feed inlet at the top and a discharge outlet at the bottom. The discharge outlet is connected to a static mixer. The feed inlet is connected to a feeding pump through a pipeline.

[0004] The above-mentioned device directly puts the raw materials into the mixing tank for stirring. However, the powdered raw materials are prone to clumping due to moisture, which makes it difficult to disperse the raw materials after feeding, resulting in uneven mixing and affecting the stability of the coating components.

[0007] A further improvement of this utility model is that: a raw material collection box is fixedly connected to the top of the support block, the bottom of the inner wall of the raw material collection box slopes downward from back to front, a conveying pipe is fixedly connected to the front side of the raw material collection box, and a feeding valve is fixedly connected to the middle of the conveying pipe.

[0008] A further improvement of this utility model is that the crushing mechanism includes a drive motor and a crushing box. The drive motor is fixedly connected to the top of the motor base, and the crushing box is fixedly connected to the top of the raw material collection box. A feed hopper is fixedly connected to the top of the crushing box. Guide plates are fixedly connected to the front and rear sides inside the crushing box. The guide plates are inclined from top to bottom towards the inside of the crushing box. Rotary shafts are rotatably connected to the left and right sides inside the crushing box. Crushing rollers are fixedly connected to the surface of the rotating shafts. The crushing rollers on both sides mesh with each other. The rotating shaft extends through to the outside of the crushing box and is fixedly connected to a transmission spur gear. The two transmission spur gears mesh with each other. The end of the rear rotating shaft is fixedly connected to the output end of the drive motor. A protective shell is provided on the outside of the transmission spur gear.

[0009] A further improvement of the present invention is that: a mixing tank is fixedly connected to the top of the mixing tank support, the bottom of the mixing tank is funnel-shaped, a discharge valve is fixedly connected to the bottom of the mixing tank, and a feed pipe is fixedly connected to the top of the mixing tank, the feed pipe penetrating into the interior of the mixing tank and fixedly connected thereto.

[0010] A further improvement of the present invention is that the stirring mechanism includes a stirring motor, the stirring motor is fixedly connected to the top of the mixing tank, the output end of the stirring motor extends into the interior of the mixing tank and is fixedly connected to an inner stirring rod, the bottom of the inner stirring rod is rotatably connected to an outer stirring rod, and a partition is rotatably connected to the surface of the inner stirring rod.

[0011] The surface of the inner stirring rod is fixedly connected to a drive gear, and the drive gear is meshed with a transmission gear. The transmission gear is rotatably connected to the surface of the mixing tank. The top of the inner wall of the mixing tank is rotatably connected to an internal gear, which meshes with the transmission gear. The internal gear is connected to the drive gear through the transmission gear. The top of the outer stirring rod is fixedly connected to the surface of the internal gear, and the partition is fixedly connected to the bottom of the drive gear.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model provides a raw material blending device for fire-retardant coatings. Before blending, solid raw materials are first crushed in a crushing mechanism. The crushed raw materials are then transported to the inside of a mixing tank through a raw material collection box. The remaining raw materials are then added to the mixing tank and mixed by a stirring mechanism. Since powdered raw materials are prone to moisture absorption and clumping, crushing the raw materials by the crushing mechanism can break up the clumps, disperse the originally agglomerated particles, restore the original particle size of the raw materials, and avoid uneven mixing caused by directly adding clumps. This ensures that the raw material components participate evenly in subsequent reactions. Crushing also makes the raw material particles smaller and the particle size distribution more uniform, increasing the contact area of ​​the raw materials, allowing different raw material particles to fully contact and interweave, improving the uniformity of mixing, and laying the foundation for the subsequent blending of stable fire-retardant coatings.

[0013] 2. This utility model provides a raw material blending device for fireproof coating processing. By starting the drive motor, the rotating shaft is driven to rotate, which in turn drives the transmission spur gear to rotate. The meshing of the two transmission spur gears drives the two crushing rollers to mesh with each other. Then, the raw material is put into the feed hopper and guided by the guide plate to the meshing point of the two crushing rollers, thereby realizing the crushing of the raw material. The crushed raw material falls into the raw material collection box. By opening or closing the feeding valve, the crushed raw material can be stored or fed.

[0014] 3. This utility model provides a raw material mixing device for fireproof coating processing. The raw materials are fed into the mixing tank by closing the discharge valve and opening the feed valve. The remaining raw materials are then fed into the mixing tank through the feed pipe. A stirring motor is then activated, driving the inner stirring rod to rotate. The inner stirring rod, in turn, drives the drive gear, which in turn drives the inner gear via a transmission gear. The inner gear, in turn, drives the outer stirring rod. Because the drive gear and the inner gear rotate in opposite directions, the forward and reverse rotation of the inner and outer stirring rods creates a complex convection cycle: the forward rotation of the inner stirring rod pushes the raw materials outward, while the reverse rotation of the outer stirring rod gathers the raw materials inward, reducing dead zones in the mixing process. This also enhances bidirectional shear force, quickly breaking up raw material agglomerates, thereby improving dispersion uniformity and shortening mixing time. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-6 As shown, this utility model has the following three specific embodiments.

[0020] Example 1 This utility model provides a fireproof coating processing raw material mixing equipment, including a base plate 11, a support block 12 fixedly connected to the top rear side of the base plate 11, a motor base 13 fixedly connected to the top of the support block 12, and a mixing tank support 14 fixedly connected to the top front side of the base plate 11. It also includes a crushing mechanism 2, a mixing tank 41, a stirring mechanism 5, and a raw material collection box 31; The crushing mechanism 2 is located on top of the support block 12 for crushing raw materials; Mixing tank 41 is used to provide space for mixing raw materials; The stirring mechanism 5 is installed inside the mixing tank 41 for stirring the raw materials; The raw material collection box 31 is used to transport the raw materials crushed by the crushing mechanism 2 into the interior of the mixing tank 41.

[0021] In this embodiment, as Figure 1 As shown, before mixing, the solid raw materials are first crushed in the crushing mechanism 2, and then the crushed raw materials are transported to the inside of the mixing tank 41 through the raw material collection box 31. Then, the remaining raw materials are put into the mixing tank 41 and mixed by the stirring mechanism 5. Since the powdered raw materials are prone to moisture and clumping, the crushing mechanism 2 can break up the clumps, disperse the originally agglomerated particles, restore the original particle size of the raw materials, avoid the uneven mixing caused by directly feeding the clumps, and ensure that the raw material components participate in the subsequent reaction evenly. Crushing can also make the raw material particles smaller and the particle size distribution more uniform, increase the contact area of ​​the raw materials, and allow different raw material particles to fully contact and interweave, improve the mixing uniformity, and lay the foundation for the subsequent mixing of a stable fireproof coating.

[0023] The crushing mechanism 2 includes a drive motor 28 and a crushing box 21. The drive motor 28 is fixedly connected to the top of the motor base 13, and the crushing box 21 is fixedly connected to the top of the raw material collection box 31. A feed hopper 22 is fixedly connected to the top of the crushing box 21. Guide plates 23 are fixedly connected to the front and rear sides inside the crushing box 21. The guide plates 23 are inclined from top to bottom into the crushing box 21. Rotary shafts 24 are rotatably connected to the left and right sides inside the crushing box 21. Crushing rollers 25 are fixedly connected to the surface of the rotating shafts 24. The crushing rollers 25 on both sides mesh with each other. The rotating shaft 24 extends through to the outside of the crushing box 21 and is fixedly connected to a transmission spur gear 26. The two transmission spur gears 26 mesh with each other. The end of the rear rotating shaft 24 is fixedly connected to the output end of the drive motor 28. A protective shell 27 is provided on the outside of the transmission spur gear 26.

[0024] In this embodiment, as Figure 2-4As shown, the drive motor 28 is started to drive the rotating shaft 24 to rotate, which in turn drives the transmission spur gear 26 to rotate. The meshing of the two transmission spur gears 26 drives the two crushing rollers 25 to mesh with each other. Then, the raw material is put into the feed hopper 22 and guided by the guide plate 23 to the meshing point of the two crushing rollers 25, thereby crushing the raw material. The crushed raw material falls into the raw material collection box 31. By opening or closing the feeding valve 33, the crushed raw material can be stored or fed.

[0025] Example 3 The difference from Embodiment 2 is that this embodiment discloses a mixing tank 41 and a stirring mechanism 5; Preferably, a mixing tank 41 is fixedly connected to the top of the mixing tank support 14, the bottom of the mixing tank 41 is funnel-shaped, a discharge valve 42 is fixedly connected to the bottom of the mixing tank 41, a feed pipe 43 is fixedly connected to the top of the mixing tank 41, and a conveying pipe 32 passes through the interior of the mixing tank 41 and is fixedly connected thereto.

[0026] The stirring mechanism 5 includes a stirring motor 51, which is fixedly connected to the top of the mixing tank 41. The output end of the stirring motor 51 extends into the interior of the mixing tank 41 and is fixedly connected to an inner stirring rod 52. An outer stirring rod 53 is rotatably connected to the bottom of the inner stirring rod 52, and a partition 57 is rotatably connected to the surface of the inner stirring rod 52.

[0027] A drive gear 54 is fixedly connected to the surface of the inner stirring rod 52. A transmission gear 55 meshes with the outside of the drive gear 54. The transmission gear 55 is rotatably connected to the surface of the mixing tank 41. An inner gear 56 is rotatably connected to the top of the inner wall of the mixing tank 41. The inner gear 56 meshes with the transmission gear 55. The inner gear 56 is connected to the drive gear 54 through the transmission gear 55. The top of the outer stirring rod 53 is fixedly connected to the surface of the inner gear 56. A partition 57 is fixedly connected to the bottom of the drive gear 54.

[0028] In this embodiment, as Figure 4-6As shown, by closing the discharge valve 42 and opening the feed valve 33, the raw materials are transported into the mixing tank 41. Then, the remaining raw materials are transported into the mixing tank 41 through the feed pipe 43. The stirring motor 51 is then started, driving the inner stirring rod 52 to rotate. The inner stirring rod 52 drives the drive gear 54 to rotate, which in turn drives the inner gear 56 through the transmission gear 55. The inner gear 56 then drives the outer stirring rod 53 to rotate. Because the drive gear 54 and the inner gear 56 rotate in opposite directions, the forward and reverse rotation of the inner and outer stirring rods 52 and 53 creates a complex convection cycle: the forward rotation of the inner stirring rod 52 pushes the raw materials outward, while the reverse rotation of the outer stirring rod 53 gathers the raw materials inward, reducing dead zones in the mixing process. This also enhances the bidirectional shear force, quickly breaking up raw material agglomerates, thereby improving dispersion uniformity and shortening the mixing time.

[0029] The working principle of this utility model is as follows: The drive motor 28 is started to rotate the shaft 24, which in turn drives the transmission spur gear 26 to rotate. The meshing of the two transmission spur gears 26 drives the two crushing rollers 25 to mesh with each other. The raw material is then fed into the feed hopper 22 and guided by the guide plate 23 to the meshing point of the two crushing rollers 25, thereby crushing the raw material. The crushed raw material falls into the raw material collection box 31. By closing the discharge valve 42 and opening the feed valve 33, the raw material is transported into the mixing tank 41. Then, the remaining raw material is transported into the mixing tank 41 through the feed pipe 43. Inside tank 41, the stirring motor 51 is activated, driving the inner stirring rod 52 to rotate. The inner stirring rod 52 then drives the drive gear 54 to rotate, which in turn drives the inner gear 56 via the transmission gear 55. The inner gear 56 then drives the outer stirring rod 53 to rotate. Since the drive gear 54 and the inner gear 56 rotate in opposite directions, the forward and reverse rotation of the inner and outer stirring rods 52 and 53 creates a complex convection cycle: the forward rotation of the inner stirring rod 52 pushes the raw material outward, while the reverse rotation of the outer stirring rod 53 gathers the raw material inward, reducing dead zones in the mixing process. This also enhances the bidirectional shear force, quickly breaking up raw material agglomerates, thereby improving dispersion uniformity and shortening the mixing time.
