Description

Technical Field

[0001] This invention relates to the field of refractory brick production, specifically to a raw material batching device and its preparation method for producing high-strength lightweight refractory bricks. Background Technology

[0002] High-strength lightweight refractory bricks, with their excellent mechanical strength and lightweight characteristics, are widely used in high-temperature operating scenarios such as industrial kilns and thermal equipment. Their production quality directly determines the service life and operational safety of related equipment. The uniformity of raw material batching is the core prerequisite for ensuring the uniformity of the texture of high-strength lightweight refractory bricks and reducing the defect rate. The performance of the batching device directly affects the batching efficiency and mixing effect, thereby restricting the production quality and capacity release of refractory bricks.

[0003] Currently, the raw material batching process in the production of high-strength lightweight refractory bricks suffers from numerous technical deficiencies. Existing batching equipment is mostly complex in structure and cumbersome to operate, requiring significant manpower for debugging and operation, resulting in high maintenance costs. Furthermore, it struggles to achieve convenient and efficient batching operations, failing to meet the demands of large-scale production. In the raw material mixing process, existing equipment often employs a single stirring or rotating method, achieving only preliminary mixing without a synergistic mixing structure design, leading to poor mixing results.

[0004] Specifically, some batching devices rely solely on stirring blades to mix raw materials, but the mixing range is limited and there are dead zones. For the various coarse and fine particles and powder raw materials required for the production of high-strength lightweight refractory bricks, it is difficult to achieve all-round uniform mixing, and problems such as raw material agglomeration and segregation are prone to occur, resulting in uneven distribution of raw material components after batching. Other devices only achieve mixing through the simple rotation of the batching box, lacking auxiliary stirring structures. The raw materials are difficult to fully contact and blend during the movement, which also fails to achieve the ideal mixing effect. Summary of the Invention

[0005] The purpose of this invention is to provide a raw material batching device and its preparation method for the production of high-strength lightweight refractory bricks, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A raw material batching device for producing high-strength lightweight refractory bricks includes a horizontal platform, an inclined platform, and an annular frame. The inclined platform is connected to the side of the horizontal platform, and its highest point is flush with the horizontal platform. Two drive shafts are rotatably connected to the horizontal platform, and drive columns are fixedly connected to both ends of the drive shafts. The annular frame includes two rings of equal diameter, which are placed on the two drive columns respectively. Several parallel connecting rods are fixedly connected between the rings. A power assembly for driving at least one drive shaft to rotate is provided on the top of the horizontal platform. A batching box is fixedly connected between the two annular frames.

[0008] As a further embodiment of the present invention: the mixing box includes a central cylindrical section and conical sections fixed at both ends of the cylindrical section, wherein a discharge port is provided at the end of one of the conical sections, a sealing structure is provided at the discharge port, and a feed pipe is provided at the middle of the cylindrical section.

[0009] As a further embodiment of the present invention: a second motor is fixedly connected to one end of the mixing box away from the discharge port, the output shaft of the second motor passes through the mixing box and is rotatably connected to the mixing box, and a stirring blade is fixedly connected to the end of the output shaft of the second motor.

[0010] As a further embodiment of the present invention: an elastic diaphragm is fixedly connected inside the mixing box, and the elastic diaphragm is connected to the output shaft of the second motor through a ball joint. An L-shaped rod is fixedly connected to the outside of the output shaft of the second motor, and the elastic diaphragm deforms under the compression of the L-shaped rod.

[0011] As a further embodiment of the present invention: the inner wall of the mixing box is fixedly connected with several protrusions in a staggered manner, and the driving column is fixed with a limiting edge to prevent the ring frame from falling off the driving column.

[0012] As a further embodiment of the present invention: two sets of stirring auxiliary components are symmetrically arranged on both sides of the mixing box. The stirring auxiliary components include at least one telescopic component, which is slidably connected to the ring frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a simple structure and is convenient to use.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Please refer to the attached figure. A raw material batching device for the production of high-strength lightweight refractory bricks and its preparation method are described. The device includes a horizontal platform 1, an inclined platform 2, and a ring frame 3. The inclined platform 2 is connected to the side of the horizontal platform 1, and its highest point is flush with the horizontal platform 1. This design facilitates the smooth transfer of raw materials between the platforms and provides a convenient operating basis for subsequent batching operations.

[0031] On the platform 1, two drive shafts 4 are rotatably connected. These two drive shafts 4 are the core carriers for power transmission of the device. Drive columns 5 are fixedly connected to both ends of the shafts to support and drive the ring frame 3 to move. At the same time, in order to prevent the ring frame 3 from falling off the drive columns 5 during the movement, the drive columns 5 are also fixed with limiting edges to restrict its fall.

[0032] The ring frame 3 serves as the mounting carrier for the batching box 9. It consists of two rings 6 of equal diameter. The two rings 6 are respectively placed on the drive columns 5 of the two drive shafts 4. Several parallel connecting rods 7 are fixedly connected between the rings 6. Through the connecting action of the connecting rods 7, the two rings 6 form a stable overall structure, ensuring the stability of the batching box 9 during operation.

[0033] To drive the ring frame 3 and the mixing box 9, a power assembly 8 is installed on the top of the platform 1. This power assembly 8 can drive at least one drive shaft 4 to rotate, thereby driving the entire device. Specifically, the power assembly 8 includes a first motor 10 fixed to the platform 1. The first motor 10 is connected to one of the drive shafts 4 via a sprocket mechanism, while the two drive shafts 4 are synchronously driven by a pulley mechanism or a sprocket mechanism to ensure that the two drive shafts 4 rotate at the same speed and prevent the ring frame 3 from shifting. Alternatively, other drive mechanisms can be used to achieve the drive, but the two drive shafts 4 must rotate synchronously to provide a stable driving force to the ring frame 3.

[0034] A batching box 9 is fixedly connected between two ring-shaped frames 3. The batching box 9 is the core container for raw material batching, and its structural design directly affects the uniformity and efficiency of batching. The batching box 9 includes a cylindrical section 11 in the middle and conical sections 12 fixed at both ends of the cylindrical section 11. One of the conical sections 12 has a discharge port 13 at its end for discharging the batched raw materials. The discharge port 13 is equipped with a sealing structure to prevent raw material leakage during the batching process. A feed pipe 14 is located in the middle of the cylindrical section 11 as a raw material input channel, facilitating the introduction of various refractory brick production raw materials into the batching box 9. The sealing structure can use a sealing cap, which is connected to the outside of the discharge port 13 by a threaded connection. Alternatively, a valve can be used for sealing. When needed, the valve or sealing cap can be opened to discharge the mixed raw materials.

[0035] To ensure thorough mixing of the raw materials, a second motor 15 is fixedly connected to one end of the mixing box 9 away from the discharge port 13. The second motor 15 serves as a stirring power source, with its output shaft passing through the mixing box 9 and rotatably connected to it. A stirring blade 16 is fixedly connected to the end of the output shaft. When the second motor 15 starts, it drives the stirring blade 16 to rotate inside the mixing box 9, thus mixing the raw materials.

[0036] Meanwhile, an elastic diaphragm 17 is fixedly connected inside the mixing box 9. The elastic diaphragm 17 is connected to the output shaft of the second motor 15 through a ball joint 18, and an L-shaped rod 19 is fixedly connected to the outside of the output shaft of the second motor 15. When the second motor 15 is running, the output shaft will drive the L-shaped rod 19 to rotate synchronously. During the rotation, the L-shaped rod 19 will continuously squeeze the elastic diaphragm 17, causing the elastic diaphragm 17 to deform. This deformation can further disturb the raw materials inside the mixing box 9, improve the uniformity of mixing, and prevent the raw materials from clumping.

[0037] In addition, the inner wall of the mixing box 9 is fixedly connected with several protrusions 20 in a staggered manner. These protrusions 20 can block and divert the raw materials when the mixing blade 16 is mixing the raw materials, break the flow inertia of the raw materials, further enhance the mixing effect, and ensure that all kinds of raw materials are mixed evenly.

[0038] To further improve the mixing quality, two sets of mixing auxiliary components 21 are symmetrically arranged on both sides of the mixing tank 9. These components can cause the raw materials inside the mixing tank 9 to shake up and down by driving the ring frame 3 to jump, thus achieving multi-dimensional mixing in conjunction with the mixing blades 16. Specifically, the mixing auxiliary component 21 includes at least one telescopic member 22, which is slidably connected to the ring frame 3. When the telescopic member 22 extends from the ring frame 3, it will contact the drive column 5. The contact between the telescopic member 22 and the drive column 5 will generate a force, which will cause the ring frame 3 to jump, indirectly causing the mixing tank 9 to shake.

[0039] More specifically, the stirring auxiliary component 21 includes a base plate 23 fixed between two annular frames 3. Two electric telescopic rods 24 are fixedly connected to the base plate 23. The electric telescopic rods 24 serve as the core driving components of the telescopic members 22, and their ends are connected to the swing rods 25. The swing rods 25 have strip grooves 26 at both ends, and the ends of the telescopic members 22 are fixedly connected to limit posts 27. The limit posts 27 are slidably connected to the strip grooves 26, allowing for flexible adjustment of the position of the swing rods 25. It is worth noting that the electric telescopic rods 24 are symmetrically connected to the swing rods 25. When the telescopic rods 24 extend by the same amount, the swing rods 25 remain parallel to the central axis of the annular frame 3. At this time, the extension lengths of the telescopic members 22 are the same, and both telescopic members 22 simultaneously contact the drive post 5, generating longitudinal jumping. When the extension amounts of the two electric telescopic rods 24 are different, the swing rods 25 will be tilted. At this time, the extension amounts of the front and rear telescopic members 22 are different, resulting in different degrees of jumping when they contact the drive post 5, giving the annular frame 3 a jumping motion in the lateral tilt direction. Furthermore, the extension and retraction of the electric telescopic rod 24 during the mixing process makes the mixing process more complex and achieves better mixing results. It should be noted that a certain gap is required at the connection point between the electric telescopic rod 24 and the swing rod 25, such as... Figure 6As shown, this ensures that the extension amounts of the electric telescopic rods 24 on both sides can be different. When the electric telescopic rod 24 and the swing rod 25 are fully rotated and connected without gap, the electric telescopic rods 24 on both sides can only maintain synchronous extension and contraction. The purpose of setting the gap is to enable the electric telescopic rods 24 on both sides to achieve extension and contraction of different lengths.

[0040] A method for preparing raw materials for the production of high-strength lightweight refractory bricks, wherein the preparation method uses any of the above-mentioned raw material batching devices.

[0041] The specific preparation method includes the following steps: ① Roll the ring frame 3 upward along the inclined platform 2 so that the ring frame 3 contacts the drive column 5; ② Turn on the first motor 10 so that the ring frame 3 drives the mixing box 9 to rotate; ③ Add raw materials through the feed pipe 14 during the rotation of the mixing box 9. The feed pipe 14 is located at the rotation center of the mixing box 9 and its position remains basically unchanged during the rotation of the mixing box 9 to facilitate the addition of materials; ④ Turn on the second motor 15 so that the mixing uniformity of the raw materials inside the mixing box 9 is further improved by the movement of the stirring blade 16 and the elastic diaphragm 17; ⑤ Turn on the corresponding electric telescopic rod 24 as needed. During the extension and retraction of the electric telescopic rod 24, the ring frame 3 jumps, thereby making the raw materials fully mixed and completing the mixing.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.

No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
