Technical Field
[0001] This utility model relates to the field of refractory and flame-retardant material processing, and in particular to a mixer for efficiently mixing refractory and flame-retardant materials. Background Technology
[0002] With the development of industrialization and modernization, the application of fire-resistant and flame-retardant materials in various industries is becoming increasingly widespread. They are mainly used to improve the stability and safety of materials in high-temperature environments, and are widely used in construction, electronics, electrical engineering, aerospace, automotive, and chemical engineering. Fire-resistant and flame-retardant materials possess excellent high-temperature resistance, heat insulation, and flame-retardant properties, which are of great significance for protecting personnel safety, reducing fire accidents, and improving equipment durability. However, common mixers present some problems in practical use.
[0003] Traditional mixers mostly employ a unidirectional mixing mode. This unidirectional mixing method has significant limitations when mixing refractory and flame-retardant materials. Due to the singular mixing action and lack of multidirectional agitation, the flow path of the material within the mixing drum is relatively fixed, making thorough and uniform mixing impossible. This results in uneven distribution of different flame-retardant components, with potential localized aggregation or absence of components, severely impacting the mixing effect.
[0004] Meanwhile, fire-resistant and flame-retardant materials often have a certain degree of stickiness. During the mixing process, these materials tend to adhere to the inner wall of the mixing tank, making subsequent cleaning quite troublesome.
[0005] To address these issues, a high-efficiency mixer for mixing refractory and flame-retardant materials is proposed. Utility Model Content

A feed pipe 4 for feeding the refractory and flame-retardant material raw materials into the mixing tank 2 is fixedly connected through the right surface of the mixing tank 2. A mixing mechanism is provided inside the mixing tank 2. The mixing mechanism can uniformly mix the refractory and flame-retardant materials. The mixing mechanism includes a drive component and a mixing component. A cleaning component is provided inside the mixing tank 2.

[0033] Reference Figure 1 - Figure 3The drive assembly includes a motor 51, which is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. The output shaft of the motor 51 is fixedly connected to a rotating shaft 52, and a rotating plate 53 is fixedly connected to the lower surface of the rotating shaft 52. The rotating shaft 52 and the rotating plate 53 will rotate synchronously. A sun gear 54 is fixedly connected to the inner wall of the top of the mixing tank 2. The sun gear 54, the mixing tank 2, the rotating shaft 52 and the rotating plate 53 are concentric. A planetary gear 55 is rotatably connected through the upper surface of the rotating plate 53. The stirring assembly includes a connecting block 61. One end of the upper surface of the connecting block 61 is connected to the planetary gear 55. A stirring rod 62 is fixedly connected to the lower surface of the connecting block 61. The end of the lower surface of the connecting block 61 away from the planetary gear 55 is connected to the stirring rod 62. A stirring blade 63 is fixedly connected to the outer wall of the stirring rod 62.
[0034] Reference Figure 1 , Figure 2 , Figure 4 The cleaning component includes an extension block 73, and a sealing gasket 72 is elastically connected to the inner wall of the stirring blade 63 via a compression spring 71. A scraper 74 is fixedly connected to the left surface of the extension block 73. The left end of the scraper 74 is arc-shaped, which can clean the fire-resistant and flame-retardant material adhering to the inner wall of the mixing tank 2.
[0035] Reference Figure 1 - Figure 3 The motor 51 is installed on the upper surface of the mixing tank 2. A valve is installed below the mixing tank 2 to control the opening and closing of the mixing tank 2. The rotating shaft 52 passes through and is rotatably connected to the upper surface of the mixing tank 2. The planetary gear 55 and the sun gear 54 mesh. When the planetary gear 55 revolves, it will also rotate on its own axis under the influence of the sun gear 54. The rotating shaft 52 passes through and is rotatably connected to the lower surface of the sun gear 54. The upper surface of the connecting block 61 is fixedly connected to the lower surface of the planetary gear 55. The planetary gear 55 can drive the connecting block 61 to perform circular motion. Multiple sets of stirring blades 63 are provided. The multiple sets of stirring blades 63 are evenly distributed on the outer wall of the stirring rod 62, which can stir the refractory and flame-retardant materials in the mixing tank 2.
[0036] Reference Figure 1 , Figure 2 , Figure 4 The sealing gasket 72 is piston-connected to the inner wall of the stirring blade 63. One end of the compression spring 71 is fixedly connected to the right surface of the sealing gasket 72, and the other end of the compression spring 71 is fixedly connected to the inner wall of the right side of the stirring blade 63. When the sealing gasket 72 moves to the right, it will squeeze the compression spring 71 to generate a reaction force. The sealing gasket 72, the extension block 73 and the scraper 74 can all retract to avoid excessive scraping force on the inner wall of the mixing tank 2 and to prevent damage to the inner wall of the mixing tank 2. The extension block 73 is slidably connected to the left surface of the stirring blade 63.
[0037] Working principle: When using this device, first start the motor 51 and add the refractory and flame-retardant material raw material into the mixing tank 2 through the feed pipe 4. When the motor 51 starts, it will drive the rotating shaft 52 and the rotating plate 53 to rotate. The rotating plate 53 will drive the planetary gear 55 to revolve around the rotating plate 53. The revolving planetary gear 55 will drive the connecting block 61, the stirring rod 62 and the stirring blade 63 to rotate synchronously, stirring the refractory and flame-retardant material raw material inside the mixing tank 2. Since the planetary gear 55 meshes with the star gear 54, it will also rotate on its own axis when it revolves, which will drive the connecting block 61, the stirring rod 62 and the stirring blade 63 to rotate around the planetary gear 55, thereby improving the stirring effect and ensuring the uniformity of the stirring.
[0038] When the stirring blade 63 rotates, it drives the compression spring 71, sealing gasket 72, extension block 73 and scraper 74 to rotate synchronously. The rotating scraper 74 will intermittently contact the inner wall of the mixing tank 2, thereby scraping off the fire-resistant and flame-retardant material adhering to the inner wall of the mixing tank 2, avoiding waste and reducing the difficulty of subsequent cleaning. After the mixing is completed, the motor 51 is turned off and the valve installed at the bottom of the mixing tank 2 is opened, and the fire-resistant and flame-retardant material will fall into the collection tank 3 and be collected for subsequent use.
