Description

Technical Field

[0001] This utility model belongs to the field of thermal insulation brick preparation technology, and specifically relates to an aggregate mixing device for preparing building thermal insulation bricks. Background Technology

[0002] Thermal insulation bricks mainly include lightweight clay, lightweight high-alumina, and silica-based products. Silica-based thermal insulation bricks are a high-temperature insulation material characterized by high purity, high strength, high load-bearing capacity, low porosity, and low impurity content. They exhibit strong resistance to acidic gas corrosion, good high-temperature dimensional stability, and a maximum operating temperature of 1420 degrees Celsius. In industrial kilns, they play a role in heat insulation, reducing energy consumption, and improving thermal efficiency, while also effectively protecting the inner refractory material and extending the kiln's service life. They are increasingly widely used in various high-temperature melting furnace bodies. In glass furnaces, they are mainly used for regenerator walls and arches.

[0003] Thermal insulation bricks are composed of main matrix materials, binders, lightweight additives, reinforcing materials, and other functional additives. The main matrix materials are further categorized into aluminum silicate materials, silicate materials, alumina / silicon oxide, and industrial waste residues. Agglomeration is prone to occur during the mixing process. Agglomerated aggregates can affect subsequent processing, requiring the removal of these substandard aggregates, which is labor-intensive and reduces work efficiency. Utility Model Content

[0004] To address the problem of cumbersome sieving of aggregates that clump together during the mixing process, this invention proposes an aggregate mixing device for the preparation of building insulation bricks, thereby overcoming the aforementioned technical problems existing in related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an aggregate mixing device for preparing building insulation bricks, comprising a mixing component, an adjustable screening component inside the mixing component, a transmission component on the outer surface of the mixing component, and a return component on the outer surface of the mixing component. The mixing component is used to mix various raw materials, the adjustable screening component is used to separate qualified and unqualified products, the transmission component is used to make the mixing component and the return component rotate synchronously, and the return component is used to push the unqualified aggregate to move.

[0007] Furthermore, the mixing assembly includes a mixing cylinder, a motor is fixedly mounted on the outer surface of the mixing cylinder, a rotating shaft is fixedly connected to the output shaft of the motor, a stirring blade is fixedly connected to the outer surface of the rotating shaft, and the rotating shaft is rotatably connected inside the mixing cylinder.

[0008] Furthermore, the adjustable screening assembly includes a first screen, which is fixedly connected to the inside of the mixing cylinder. A second screen is slidably connected to the bottom of the first screen. A sliding plate is fixedly connected to the outer surface of the second screen. A screw is threadedly connected to the outer surface of the sliding plate. The screw is rotatably connected to the mixing cylinder. A receiving groove is provided inside the mixing cylinder.

[0009] Furthermore, the transmission assembly includes a first pulley, which is fixedly connected to the rotating shaft. A belt is mounted on the outer surface of the first pulley, and a second pulley is connected to the first pulley via the belt drive.

[0010] Furthermore, the material return assembly includes a material return cylinder, which is fixedly connected to and communicates with the mixing cylinder. The outer surface of the material return cylinder has a discharge port, and a discharge plate is fixedly connected to the outer surface of the material return cylinder.

[0011] Furthermore, a number of legs are fixedly connected to the outer surface of the mixing cylinder, and a support is fixedly connected to the outer surface of the motor.

[0012] Furthermore, a handwheel is fixedly connected to the end of the screw.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model connects an adjustable screening component and a return component, both of which are connected to a mixing component. When the mixing component pushes the aggregate through the adjustable screening component, qualified aggregate passes through the adjustable screening component and is discharged directly, while unqualified aggregate is pushed into the return component by the mixing component. Automatic screening of aggregate can be achieved at the discharge stage, reducing the labor intensity of workers, avoiding the impact of unqualified aggregate on subsequent processing, and making it more convenient to use.

[0015] 2. This utility model connects a screw and a sliding plate. When the screw is rotated, the rotational tendency of the sliding plate on the screw is blocked by the mixing cylinder. At this time, the screw can drive the sliding plate to move the second screen, so that the holes on the surface of the second screen and the first screen are staggered, thereby limiting the particle size of the output material and making the output material more refined. It can be adjusted according to different base materials and actual needs on site, making it more flexible in use.

Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0028] Please see Figures 1-6 As shown, this utility model is an aggregate mixing device for preparing building insulation bricks, including a mixing component 1, an adjustable screening component 2 inside the mixing component 1, a transmission component 3 on the outer surface of the mixing component 1, and a return component 4 on the outer surface of the mixing component 1. The mixing component 1 is used to mix various raw materials, the adjustable screening component 2 is used to separate qualified products from unqualified products, the transmission component 3 is used to make the mixing component 1 and the return component 4 rotate synchronously, and the return component 4 is used to push the unqualified aggregate to move.

[0029] Various raw materials are poured into the mixing component 1, and the mixing component 1 is started to crush, stir and mix the various raw materials. The mixed aggregate is discharged through the adjustable screen component 2 below the mixing component 1. Unqualified aggregate enters the return component 4 from the mixing component 1. The mixing component 1 drives the return component 4 to rotate synchronously through the transmission component 3, so that the return component 4 pushes away the unqualified aggregate. When mixing aggregates with different base materials, the particle size of the output can be controlled by changing the adjustable screen component 2, making it more convenient and flexible to use.

[0030] This invention connects the adjustable screening component 2 and the return component 4, both of which are connected to the mixing component 1. When the mixing component 1 pushes the aggregate through the adjustable screening component 2, qualified aggregate passes through the adjustable screening component 2 and is discharged directly, while unqualified aggregate is pushed into the return component 4 by the mixing component 1. Automatic screening of aggregate can be achieved at the discharge stage, reducing the labor intensity of workers, avoiding the impact of unqualified aggregate on subsequent processing, and making it more convenient to use.

[0031] In one embodiment, the mixing component 1 includes a mixing cylinder 101, a motor 102 is fixedly mounted on the outer surface of the mixing cylinder 101, a rotating shaft 103 is fixedly connected to the output shaft of the motor 102, a stirring blade 104 is fixedly connected to the outer surface of the rotating shaft 103, and the rotating shaft 103 is rotatably connected inside the mixing cylinder 101.

[0032] After pouring various raw materials into the mixing drum 101, start the motor 102. The output shaft of the motor 102 drives the rotating shaft 103 to rotate, and the rotating shaft 103 drives the stirring blade 104 to rotate. The stirring blade 104 pushes the raw materials in the mixing drum 101 to mix and crush them.

[0033] In one embodiment, the adjustable screening assembly 2 includes a first screen 201, which is fixedly connected to the inside of the mixing cylinder 101. A second screen 202 is slidably connected to the bottom of the first screen 201. A sliding plate 203 is fixedly connected to the outer surface of the second screen 202. A screw 204 is threadedly connected to the outer surface of the sliding plate 203. The screw 204 is rotatably connected to the mixing cylinder 101. A receiving groove 205 is provided inside the mixing cylinder 101.

[0034] When the mixing blades 104 push the mixed aggregate through the first screen 201 and the second screen 202, the qualified aggregate passes directly through the first screen 201 and the second screen 202 and is discharged. The rotation trend of the sliding plate 203 on the rotating screw 204 is blocked by the mixing cylinder 101. At this time, the screw 204 can drive the sliding plate 203 to move the second screen 202. The second screen 202 slides along the receiving groove 205. Adjusting the relative position between the second screen 202 and the first screen 201 can achieve the control of the discharge particle size.

[0035] In one embodiment, the transmission assembly 3 includes a first pulley 301, which is fixedly connected to the rotating shaft 103. A belt 302 is mounted on the outer surface of the first pulley 301, and a second pulley 303 is connected to the first pulley 301 via the belt 302.

[0036] In one embodiment, the above-mentioned material return assembly 4 includes a material return cylinder 401, which is fixedly connected to and communicates with the mixing cylinder 101. The outer surface of the material return cylinder 401 is provided with a discharge port 402, and a discharge plate 403 is fixedly connected to the outer surface of the material return cylinder 401. An auger 404 is rotatably connected inside the material return cylinder 401.

[0037] The rotating shaft 103 drives the first pulley 301 to rotate. The first pulley 301 drives the second pulley 303 to rotate synchronously through the belt 302. The second pulley 303 drives the auger 404 to rotate synchronously. After the mixing blades 104 push the unqualified aggregate into the return cylinder 401, the auger 404 rotates in the return cylinder 401 and can push the unqualified aggregate to the discharge port 402 and discharge it along the discharge plate 403 at the discharge port 402.

[0038] In one embodiment, for the mixing cylinder 101, a plurality of legs 5 are fixedly connected to the outer surface of the mixing cylinder 101, and a support 6 is fixedly connected to the outer surface of the motor 102.

[0039] The support legs 5 and the support 6 are used to support the mixing drum 101 and the motor 102 respectively, so that the mixing drum 101 and the motor 102 remain stable during operation and avoid unnecessary shaking.

[0040] In one embodiment, a handwheel 7 is fixedly connected to the end of the screw 204.

[0041] One end of the screw 204 extends to the outside of the mixing cylinder 101, and this end is fixedly connected to the handwheel 7. The outer surface of the handwheel 7 is covered with a soft pad, and the operator can push the handwheel 7 to drive the screw 204 to rotate.

[0042] In summary, using the above-described technical solution of this utility model, after various raw materials are poured into the mixing drum 101, the motor 102 is started. The output shaft of the motor 102 drives the rotating shaft 103 to rotate, and the rotating shaft 103 drives the stirring blades 104 to rotate. The stirring blades 104 push the raw materials in the mixing drum 101 to mix and crush them. When the stirring blades 104 push the mixed aggregate through the first screen 201 and the second screen 202, the qualified aggregate directly passes through the first screen 201 and the second screen 202 and is discharged. The rotating screw 204 is rotated, and the rotation trend of the sliding plate 203 on the screw 204 is blocked by the mixing drum 101. At this time, the screw 204 can drive the sliding plate 203 to rotate. Plate 203 drives the second screen 202 to move. The second screen 202 slides along the receiving groove 205. Adjusting the relative position between the second screen 202 and the first screen 201 can control the particle size of the output. The rotating shaft 103 drives the first pulley 301 to rotate. The first pulley 301 drives the second pulley 303 to rotate synchronously through the belt 302. The second pulley 303 drives the auger 404 to rotate synchronously. After the stirring blades 104 push the unqualified aggregate into the return cylinder 401, the auger 404 rotates in the return cylinder 401 and can push the unqualified aggregate to the discharge port 402 and discharge it along the discharge plate 403 at the discharge port 402.

[0043] Through the above technical solutions, 1. By connecting the adjustable screening component 2 and the return component 4, both the adjustable screening component 2 and the return component 4 are connected to the mixing component 1. When the mixing component 1 pushes the aggregate through the adjustable screening component 2, qualified aggregate passes through the adjustable screening component 2 and is directly discharged, while unqualified aggregate is pushed into the return component 4 by the mixing component 1. Automatic screening of aggregate can be achieved at the discharge stage, reducing the labor intensity of workers and avoiding unqualified aggregate from affecting subsequent processing, making it more convenient to use; 2. By connecting the screw 204 and the sliding plate 203, when the screw 204 is rotated, the rotation trend of the sliding plate 203 on the screw 204 is blocked by the mixing cylinder 101. At this time, the screw 204 can drive the sliding plate 203 to move the second screen 202, so that the holes on the surface of the second screen 202 and the first screen 201 are staggered, thereby limiting the particle size of the discharged material, making the discharged material more refined. It can be adjusted according to different base materials and actual needs on site, making it more flexible to use.
