Description

Technical Field

[0001] This utility model relates to the field of mixing equipment, specifically a mixing equipment for preparing titanium-containing calcium hexaaluminate materials. Background Technology

[0002] Titanium-containing calcium hexaaluminate is a high-performance composite refractory material. With its excellent thermal shock resistance, chemical stability and high-temperature mechanical properties, it is widely used in high-temperature industrial fields such as metallurgy, glass and ceramics. Under extreme working conditions, this material can effectively resist the erosion of high-temperature melts and mechanical scouring, significantly improving the service life of industrial kiln linings and high-temperature components. It is an indispensable key material in modern high-temperature industry.

[0003] The preparation of titanium-containing calcium hexaaluminate typically uses industrial alumina, calcium carbonate, and titanium oxide as the main raw materials, with a small amount of additives to adjust the material properties. Before use, these raw materials need to be processed into uniform fine powder through crushing, grinding and other processes. Then, a mixing process is used to ensure that the components are evenly dispersed to ensure that they can fully react in the subsequent high-temperature synthesis process and obtain a stable target product. Precise mixing of raw materials is a key step in ensuring the quality of titanium-containing calcium hexaaluminate products.

[0004] However, during the operation of existing mixing equipment, when operators pour powdered raw materials into the mixer, dust is easily generated due to the high fluidity of the powder and the low friction between particles. This floating dust not only pollutes the production workshop environment and endangers the health of operators, but also wastes raw materials and increases production costs. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a mixing device for preparing titanium-containing calcium hexaaluminate materials, so as to solve the technical problem that the dust generated during the process of pouring powdered raw materials into the mixer is very easy to float out from the port of the mixer tank.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for preparing titanium-containing calcium hexaaluminate materials, comprising a mixer, two sets of connecting columns fixed to the outer wall of the mixer, a frame sleeved on the outer wall of the connecting columns, a servo motor installed at the end of one set of the connecting columns, a mixing chamber inside the mixer, a feeder at the top of the mixer, a material gathering chamber at the top of the feeder, a through hole at the bottom of the material gathering chamber, a guide pipe connected to the bottom of the feeder, and two sets of guide blocks fixed to the inner wall of the guide pipe.

[0007] By adopting the above technical solution, the problem of dust generated during the backfilling of powdered raw materials into the mixer being easily blown out from the port of the mixer tank is solved. The powdered raw materials are poured into the aggregate bin, and the raw materials flow along the inclined inner wall of the aggregate bin towards the through hole. The raw materials flow into the guide pipe through the through hole. Two sets of guide blocks on the inner wall of the guide pipe guide the raw materials and reduce the flow speed of the raw materials. The guide pipe guides the raw materials to the inclined inner wall of the mixing bin, so that the raw materials can flow along the inclined inner wall of the mixer to the bottom of the mixing bin. This reduces the amount of floating dust generated by the collision of powder and air during the backfilling of raw materials into the mixer. In addition, the feeder blocks the floating dust inside the mixer, preventing the dust from being discharged from the mixer port.

[0008] The present invention is further configured such that the inner wall of the mixing chamber is tapered, the guide pipe is bent, and the bottom end of the guide pipe is in contact with the inner wall of the mixing chamber.

[0009] Preferably, the guide pipe guides the raw material to the inclined inner wall of the mixing chamber, so that the raw material can flow along the inclined inner wall of the mixer to the bottom of the mixing chamber, reducing the impact generated when the raw material dust falls to the bottom of the mixing chamber.

[0010] The present invention is further configured such that a support plate is fixed to the top of the mixer, and a support ring is provided at the top of the feeder.

[0011] Preferably, the feeder is placed securely on top of the mixer by supporting the support ring with a support plate.

[0012] The present invention is further provided that the top of the mixer is provided with a cover plate, and a sealing gasket is installed on the inner wall of the cover plate.

[0013] Preferably, when the cover is flipped over to cover the top of the mixer, the sealing gasket is embedded in the top of the support plate, so that the cover seals the top port of the mixer through the sealing gasket.

[0014] The present invention is further configured such that the guide blocks are inclined and the two sets of guide blocks are symmetrically staggered.

[0015] Preferably, during the flow of the raw material in the guide tube, two sets of guide blocks guide the flow of the raw material, thereby reducing the flow rate of the raw material.

[0016] The present invention is further configured such that the feeder has an air hole inside, and a first filter plate and a second filter plate are respectively installed at the top and bottom of the air hole.

[0017] Preferably, when the raw material falls into the mixing chamber from the end of the guide pipe, a small amount of dust will be generated. The gas flowing inside the mixing chamber is discharged to the outside through the air hole on the feeder. During the process of the gas being discharged from the air hole, the second filter plate and the first filter plate filter the raw material powder particles mixed in the gas one after the other, thereby reducing the amount of raw material powder floating inside the mixing chamber to float to the outside of the mixer.

[0018] The present invention is further configured such that the first filter plate and the second filter plate are movably installed at the port of the air hole, and the diameter of the filter hole of the first filter plate is smaller than the diameter of the filter hole of the second filter plate.

[0019] Preferably, the second filter plate first filters the raw material particles mixed in the gas, and then the first filter plate further filters the gas. In addition, since the first and second filter plates are movably installed at both ends of the air hole, when a large amount of powder accumulates inside the air hole, personnel can disassemble the first and second filter plates to clean the powder inside the air hole.

[0020] The present invention is further configured such that two sets of handles are installed on the top of the feeder, and the two sets of handles are arranged symmetrically.

[0021] Preferably, the feeder can be removed from the top of the mixer by means of a handle.

[0022] In summary, the present invention has the following main advantages:

[0023] 1. This utility model solves the problem of dust easily drifting out of the mixer's port during the backflow of powdered raw materials into the mixer by setting up a mixer, feeder, aggregate bin, guide pipe, and guide blocks. The powdered raw materials are poured into the aggregate bin, and the raw materials flow along the inclined inner wall of the aggregate bin towards the through hole. The raw materials flow into the guide pipe through the through hole. Two sets of guide blocks on the inner wall of the guide pipe guide the raw materials and reduce the flow speed of the raw materials. The guide pipe guides the raw materials to the inclined inner wall of the mixing bin, so that the raw materials can flow along the inclined inner wall of the mixer to the bottom of the mixing bin. This reduces the amount of floating dust generated by the collision of powder with air during the backflow of raw materials into the mixer. In addition, the feeder blocks the floating dust inside the mixer, preventing the dust from being discharged from the mixer port.

[0024] 2. By setting up air holes, a first filter plate, and a second filter plate, when the raw material falls into the mixing chamber from the end of the guide pipe, a small amount of dust will be generated. The gas flowing inside the mixing chamber is discharged to the outside through the air holes on the feeder. During the process of the gas being discharged from the air holes, the second filter plate and the first filter plate filter the raw material powder particles mixed in the gas one after the other, thereby reducing the amount of raw material powder floating inside the mixing chamber that floats to the outside of the mixer.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] First embodiment:

[0036] Please see Figure 1 — Figure 5The mixer includes a mixer 1, with two sets of connecting columns 103 fixed to its outer wall. A frame 3 is fitted around the outer wall of each connecting column 103. A servo motor 104 is installed at the end of each connecting column 103. A mixing chamber 101 is located inside the mixer 1. A feeder 4 is located on the top of the mixer 1. A material collection bin 401 is located on the top of the feeder 4. A through hole 402 is located at the bottom of the material collection bin 401. A guide pipe 5 is connected to the bottom of the feeder 4. Two sets of guide blocks 501 are fixed to the inner wall of the guide pipe 5. This design solves the problem that dust generated during the pouring of powdered raw materials into the mixer can easily escape from the port of the mixer tank. The powdered raw materials are poured into the material collection bin... In the material bin 401, the raw material flows along the inclined inner wall of the material bin 401 to the through hole 402. The raw material flows into the guide pipe 5 through the through hole 402. Two sets of guide blocks 501 on the inner wall of the guide pipe 5 guide the raw material and reduce the flow speed of the raw material. The guide pipe 5 guides the raw material to the inclined inner wall of the mixing bin 101, so that the raw material can flow along the inclined inner wall of the mixer 1 to the bottom of the mixing bin 101. This reduces the amount of floating dust generated by the collision of powder and air during the backflow of the raw material into the mixer 1. In addition, the feeder 4 blocks the floating dust inside the mixer 1 to prevent the dust from being discharged from the port of the mixer 1.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 4 The inner wall of the mixing chamber 1 is tapered, and the guide pipe 5 is bent. The bottom end of the guide pipe 5 is in contact with the inner wall of the mixing chamber 1. The guide pipe 5 guides the raw material to the inclined inner wall of the mixing chamber 101, so that the raw material can flow along the inclined inner wall of the mixer 1 to the bottom of the mixing chamber 101, reducing the impact generated when the raw material dust falls to the bottom of the mixing chamber 101.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 and Figure 4 A support plate 102 is fixed on the top of the mixer 1, and a support ring 404 is provided on the top of the feeder 4. The support plate 102 supports the support ring 404, so that the feeder 4 is placed stably on the top of the mixer 1.

[0039] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The top of the mixer 1 is provided with a cover plate 2, and a sealing gasket 201 is installed on the inner wall of the cover plate 2. When the cover plate 2 is flipped over to cover the top of the mixer 1, the sealing gasket 201 is embedded in the top of the support plate 102, so that the cover plate 2 seals the top port of the mixer 1 through the sealing gasket 201.

[0040] For details regarding the above embodiments, please refer to [link / reference]. Figure 5The guide block 501 is inclined and the two sets of guide blocks 501 are symmetrically staggered. During the flow of the raw material in the guide pipe 5, the two sets of guide blocks 501 guide the raw material, thereby reducing the flow speed of the raw material.

[0041] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The feeder 4 has an air hole 602 inside. The top and bottom of the air hole 602 are respectively equipped with a first filter plate 6 and a second filter plate 601. When the raw material falls into the mixing chamber 101 from the end of the guide pipe 5, a small amount of dust will be generated. The gas flowing inside the mixing chamber 101 is discharged to the outside through the air hole 602 on the feeder 4. During the process of the gas being discharged from the air hole 602, the second filter plate 601 and the first filter plate 6 filter the raw material powder particles mixed in the gas one after the other, thereby reducing the amount of raw material powder floating inside the mixing chamber 101 that floats to the outside of the mixer 1.

[0042] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The first filter plate 6 and the second filter plate 601 are movably installed at the port of the air hole 602, and the diameter of the filter hole of the first filter plate 6 is smaller than that of the filter hole of the second filter plate 601. The second filter plate 601 first filters the raw material particles mixed in the gas, and then the first filter plate 6 further filters the gas. In addition, since the first filter plate 6 and the second filter plate 601 are movably installed at both ends of the air hole 602, when a large amount of powder accumulates inside the air hole 602, personnel can disassemble the first filter plate 6 and the second filter plate 601 to clean the powder inside the air hole 602.

[0043] For details regarding the above embodiments, please refer to [link / reference]. Figure 2 Two sets of handles 403 are installed on the top of the feeder 1, and the two sets of handles 403 are symmetrically arranged. Personnel can remove the feeder 4 from the top of the mixer 1 through the handles 403.

[0044] Second embodiment:

[0045] Please see Figure 6 A shield 7 is installed on the top of the first filter plate 6, and the shield 7 is fixedly installed on the top of the feeder 1. When the personnel pour the raw material into the material hopper 401, the raw material will not cover the top of the first filter plate 6, so as to avoid the raw material from affecting the first filter plate 6 in filtering the gas discharged from the mixer 1 during the process of pouring the raw material into the mixer 1.

[0046] In practical operation, before pouring raw materials into the mixer 1, the feeder 4 is placed at the top port of the mixer 1. Then, the powdered raw materials are poured into the aggregate bin 401. The raw materials flow along the inclined inner wall of the aggregate bin 401 towards the through hole 402. The raw materials flow through the through hole 402 into the guide pipe 5. During the flow of the raw materials in the guide pipe 5, two sets of guide blocks 501 on the inner wall of the guide pipe 5 guide the raw materials, and the guide blocks 501 can reduce the flow velocity of the raw materials. The guide pipe 5 guides the raw materials to the mixing bin 101. The inclined inner wall allows the raw material to flow along the inclined inner wall of the mixer 1 to the bottom of the mixing chamber 101. When the raw material falls into the mixing chamber 101 from the end of the guide pipe 5, a small amount of dust will be generated. The gas flowing inside the mixing chamber 101 is discharged to the outside through the air hole 602 on the feeder 4. During the process of the gas being discharged from the air hole 602, the second filter plate 601 and the first filter plate 6 filter the raw material powder particles mixed in the gas one after the other, thereby reducing the amount of raw material powder floating inside the mixing chamber to float to the outside of the mixer 1.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
