Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically a mixer for the production of aluminum silicate cotton. Background Technology

[0002] Alumina silicate cotton is an inorganic fiber material made primarily from raw materials such as fused silica, high-purity alumina, and silica through high-temperature melting and fiberization. It features low thermal conductivity, excellent thermal insulation performance, good chemical stability, non-corrosiveness, and sound absorption and noise reduction properties. It is commonly used for thermal insulation in industrial kilns, heating devices, and high-temperature pipelines, as well as for fireproofing, thermal insulation, and sound absorption in the construction industry. It is a widely used high-performance thermal insulation material.

[0003] The production of aluminosilicate cotton generally includes raw material mixing, melting, and fiberization. In the raw material mixing stage, various raw materials such as alumina and silica need to be mixed evenly in a certain proportion. A stirring device can ensure that these raw materials come into full contact and mix, guaranteeing the uniformity of the raw material composition. This is crucial for the stability of the subsequent product quality. A search revealed Chinese patent application CN201810229531.6, which discloses a stirring device including a stirring tank, a stirring shaft, and a motor. The stirring shaft has an inner end and an outer end; stirring blades are provided at the bottom of the inner end; a storage tank is provided at the top of the outer end and sealed to the stirring shaft; at least two outwardly protruding hollow outlet pipes are provided on the shaft body located within the stirring tank; the outlet pipes form a pipe-shaft connection with the stirring shaft; the stirring shaft is hollow from the pipe-shaft connection to the top of the outer end; the storage tank, the stirring shaft, and the outlet pipes are connected through a hollow pipe formed by the hollow structure; the stirring shaft is solid from the pipe-shaft connection to the bottom of the inner end.

[0004] However, the above-mentioned technical solutions and existing mixers have many shortcomings. For example, the mixing structure is simple and mostly uses a single mixing blade, which makes it difficult to fully and evenly mix raw materials such as bauxite, kaolin, and silica. This results in unstable performance of aluminum silicate cotton, such as inconsistent fiber diameter and large differences in thermal insulation performance. Utility Model Content

[0005] The purpose of this invention is to provide a mixer for the production of aluminum silicate cotton, which solves the problem that the single mixing blade of the existing mixer is not enough to fully mix the raw materials, thereby ensuring the stability of the performance of aluminum silicate cotton and reducing problems such as inconsistent fiber diameter and large differences in heat insulation performance, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A mixer for producing aluminosilicate cotton, comprising:

[0008] A mixing chamber used for stirring and mixing aluminum silicate cotton raw materials;

[0009] The mixing chamber includes an upper chamber and a lower chamber. The upper chamber is cylindrical and the lower chamber is hemispherical. The upper chamber is covered with a cover and has a feed inlet. The lower chamber has a discharge outlet at the bottom.

[0010] It also includes a stirring mechanism for mixing materials in the mixing chamber;

[0011] The stirring mechanism includes a shaft and a motor rotatably mounted on the top of the bin cover. The motor is mounted on the top of the bin cover to drive the shaft. Three sets of fixed sleeves are sleeved on the shaft from top to bottom. The outer walls of the three sets of fixed sleeves are respectively provided with a first stirring blade, a second stirring blade, and a third stirring blade.

[0012] Preferably, the first stirring blade is designed as a flat plate, the second stirring blade is designed as a turbine to form a spiral upward flow to enhance the mixing effect, and the third stirring blade is designed as an inclined anchor. The third stirring blade and the inner wall of the lower chamber are designed with a small gap to lift the raw materials at the bottom of the lower chamber and prevent the raw materials from settling.

[0013] Preferably, the end of the first stirring blade is provided with a scraper for scraping off the raw material adhering to the inner wall of the upper chamber. The scraper has a slightly spiral design and one side of the scraper has a wedge design. The scraper and the inner wall of the upper chamber are fitted with a small gap.

[0014] Preferably, the fixing sleeve is fixed to the shaft by fixing screws, the shaft has screw holes, and the fixing sleeve has fixing holes for the fixing screws to pass through.

[0015] Preferably, a side plate is provided on one side of the top of the bin cover, a motor is installed on one side of the side plate, a drive gear is provided at the output end of the motor, and a driven gear that meshes with the drive gear is provided at one end of the shaft located at the top of the bin cover.

[0016] Preferably, it also includes a heating mechanism for heating the materials in the mixing chamber. The heating mechanism includes a jacket disposed on the outer wall of the upper chamber, an insulating rod disposed inside the jacket, and an electric heating wire wound on the insulating rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model incorporates three sets of stirring blades of different shapes in its stirring mechanism. The first stirring blade is flat and can initially stir and disperse the materials in the upper part of the chamber. The second stirring blade is turbine-shaped, which enables the materials to form a spiral upward flow, enhancing the mixing effect between materials. The third stirring blade is inclined and anchor-shaped, fitting with a small gap in the inner wall of the lower chamber, which can lift the raw materials at the bottom of the lower chamber, preventing the raw materials from settling and avoiding local accumulation. Through the coordinated work of these three sets of stirring blades, the materials are stirred from the upper to the lower part of the chamber in all directions, solving the problem that the single stirring blade of the existing mixer is difficult to fully mix the raw materials. This allows raw materials such as bauxite, kaolin, and silica to be fully and evenly mixed, thereby ensuring the stability of the performance of aluminum silicate cotton and reducing problems such as inconsistent fiber diameter and large differences in thermal insulation performance.

[0019] 2. The design of the third stirring blade with a small gap fit with the inner wall of the lower chamber can effectively lift the raw materials at the bottom of the lower chamber, prevent the raw materials from settling and accumulating at the bottom, ensure the consistency of the material state in the mixing chamber, facilitate uniform mixing, improve the utilization rate of raw materials, and avoid the problems of insufficient mixing and waste caused by raw material settling.

[0025] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 This utility model provides a technical solution:

[0027] A mixer for producing aluminosilicate cotton, comprising:

[0028] A mixing chamber for stirring and mixing aluminum silicate cotton raw materials; the mixing chamber includes an upper chamber 1 and a lower chamber 2. The upper chamber 1 is cylindrical and the lower chamber 2 is hemispherical. A chamber cover 4 is installed on the upper chamber 1, and a feed inlet 5 is provided on the chamber cover 4. A discharge outlet 3 is provided at the bottom of the lower chamber 2. A side plate 16 is provided on one side of the top of the chamber cover 4. A motor 17 is installed on one side of the side plate 16. A drive gear 19 is provided at the output end of the motor 17. A driven gear 18 that meshes with the drive gear 19 is provided at one end of the shaft 8 located at the top of the chamber cover 4.

[0029] It also includes a stirring mechanism for mixing materials in the mixing chamber; the stirring mechanism includes a shaft 8 rotatably mounted on the top of the chamber cover 4 and a motor 17. The motor 17 is mounted on the top of the chamber cover 4 to drive the shaft 8. Three sets of fixed sleeves 9 are sleeved on the shaft 8 from top to bottom. The outer walls of the three sets of fixed sleeves 9 are respectively provided with a first stirring blade 10, a second stirring blade 11, and a third stirring blade 12. The first stirring blade 10 has a flat plate design, the second stirring blade 11 has a turbine design to form a spiral upward flow to enhance the mixing effect, and the third stirring blade 12 has an inclined anchor design. The third stirring blade 12 and the inner wall of the lower chamber 2 are designed with a small gap to lift the raw materials at the bottom of the lower chamber 2 to prevent the raw materials from settling.

[0030] In actual use, the motor 17 drives the shaft 8 to rotate, and the three sets of fixed sleeves 9 fitted on the shaft 8 rotate accordingly. The first stirring blade 10, the second stirring blade 11, and the third stirring blade 12 on the outer wall of the fixed sleeve 9 begin to work. The flat-plate type first stirring blade 10 stirs and disperses the material in the upper part of the chamber; the turbine-shaped second stirring blade 11 promotes the material to form a spiral upward flow during rotation, increasing the chance of mixing between materials; the inclined anchor-shaped third stirring blade 12, because it has a small gap fit with the inner wall of the lower chamber 2, can lift the raw material at the bottom of the lower chamber 2 when rotating, avoiding the raw material from settling.

[0031] In summary, by designing stirring blades of different shapes to stir materials from multiple levels and angles, the problem of simple stirring structure and difficulty in fully mixing raw materials with a single blade in existing mixers is solved. This allows various raw materials to be fully and evenly mixed, ensuring the stability of the performance of aluminum silicate cotton and reducing problems such as inconsistent fiber diameter and large differences in thermal insulation performance caused by uneven mixing.

[0032] The outer wall of the mixing chamber is also equipped with a support ring 6, and the bottom of the support ring 6 is surrounded by a pillar 7 to support the mixing chamber.

[0033] Please see Figure 2-3 :

[0034] The end of the first stirring blade 10 is provided with a scraper 15 for scraping off the raw material adhering to the inner wall of the upper chamber 1. The scraper 15 has a slightly spiral design and one side of the scraper 15 has a wedge design. The scraper 15 and the inner wall of the upper chamber 1 are fitted with a small gap.

[0035] When in use, the scraper 15 at the end of the first stirring blade 10 rotates synchronously along the inner wall of the upper chamber 1 as the first stirring blade 10 rotates with the shaft 8. The scraper 15 is slightly spiral and one side is wedge-shaped, which fits with the inner wall of the upper chamber 1 with a small gap. During the rotation, the scraper 15 can scrape off the raw materials attached to the inner wall of the upper chamber 1, so that they can re-participate in the mixing.

[0036] This design effectively prevents raw materials from adhering to the inner wall of the upper chamber 1, avoids raw material residue leading to uneven mixing, improves the utilization rate of raw materials, further enhances the mixing effect, and ensures the quality of each stirring.

[0037] Please see Figure 2-3 :

[0038] The fixing sleeve 9 is fixed to the shaft 8 by fixing screws. The shaft 8 has screw holes 14, and the fixing sleeve 9 has fixing holes 13 for the fixing screws to pass through.

[0039] The fixing sleeve 9 is fixed to the shaft 8 by fixing screws. The fixing hole 13 on the fixing sleeve 9 corresponds to the screw hole 14 on the shaft 8. By passing the fixing screw through the fixing hole 13 and screwing it into the screw hole 14, the fixing sleeve 9 can be firmly fixed to the shaft 8, ensuring that the stirring blade can stably follow the rotation of the shaft 8. This connection method is convenient and quick, and it is easy to disassemble, replace or maintain the three sets of stirring blades when needed, which improves the maintainability and flexibility of the mixer and ensures the long-term stable operation of the stirring mechanism.

[0040] Please see Figure 1 and Figure 4 :

[0041] It also includes a heating mechanism for heating the materials in the mixing chamber. The heating mechanism includes a jacket 20 installed on the outer wall of the upper chamber 1, an insulating rod 21 installed inside the jacket 20, and an electric heating wire 22 wound around the insulating rod 21. The heating mechanism can preheat the materials in the mixing chamber, which facilitates the subsequent melting of the materials and improves the production and processing efficiency of aluminum silicate cotton.

[0042] The jacket 20 of the heating mechanism is set on the outer wall of the upper chamber 1. The electric heating wire 22 wound on the insulating rod 21 inside the jacket 20 generates heat when energized. The heat is transferred to the material in the upper chamber 1 through the jacket 20 to preheat the material, which makes the material easier to melt in the subsequent process, shortens the melting time, improves the production and processing efficiency of aluminum silicate cotton, reduces production costs, and helps to ensure the stability of product quality.

[0043] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
