Description

Technical Field

[0001] This utility model relates to the field of high alumina brick manufacturing technology, specifically to an integrated molding equipment for high alumina bricks. Background Technology

[0002] High-alumina bricks are a common refractory material, mainly made from high-alumina bauxite (Al2O3 content ≥48%). Due to their excellent refractory properties, high-temperature stability and resistance to chemical erosion, they are widely used in high-temperature equipment in industries such as metallurgy, building materials, chemicals, and power.

[0003] The manufacturing process of high-alumina bricks generally begins with raw material processing: high-alumina bauxite is crushed, calcined, and then ground into powder. This is followed by batching and mixing: binders (such as clay) and additives are added. The bricks are then formed by machine pressing or vibration molding, and finally sintered in a high-temperature tunnel kiln at 1350–1550℃. Therefore, selecting highly automated molding equipment will greatly improve work efficiency.

[0004] Currently, equipment for integrated molding of high-alumina bricks has seen significant development. For example, invention patent CN119430960A provides a method for preparing thermal shock resistant high-alumina bricks, including the following steps: S1, preparing a regulator; S2, mixing aggregates; S3, preparing a mixed material; S4, spreading the material; S5, spreading the material again; S6, making brick blanks; S7, heat preservation and drying; S8, firing. A device for preparing thermal shock resistant high-alumina bricks is also provided, comprising a mixing and grinding device, a brick press, and a tray. The mixing and grinding device includes a mixing cylinder, a rotating frame, a grinding wheel, and a scraper. A discharge port is provided on the lower part of the circumferential side of the mixing cylinder, and a guide plate is provided below the discharge port. A cover plate is provided at the upper opening of the mixing cylinder, and the cover plate has a feed port. The purpose of this invention is to solve or at least alleviate the problem of difficulty in controlling the fine pore structure in high-alumina bricks during production, and to provide a method and device for preparing thermal shock resistant high-alumina bricks.

[0005] However, devices such as those in this invention, as well as other molding equipment in the prior art, still require manual handling of the handling before and after pressing, and the degree of automation and integration needs to be improved. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides an integrated molding equipment for high-alumina bricks.

[0007] The technical solution of this utility model is:

[0008] A high-alumina brick integrated molding equipment includes a mixer and a press arranged side by side, a first conveyor belt located below the mixer and the press, and an ejector located below the first conveyor belt and corresponding to the press.

[0009] The first conveyor belt has a groove in the middle of its upper surface, and a mold box is placed inside the groove. The groove has a slot in the middle, and the top of the ejector has a top block. After the top block rises, it passes through the slot and connects with the bottom of the mold box.

[0010] Furthermore, the mixer has a discharge port at the bottom and a feed port at the top.

[0011] Note: The mixing machine is used to mix high-alumina brick materials and automatically feed them.

[0012] Furthermore, the bottom of the press is provided with a pressure plate, which has the same shape and area as the inside of the mold box.

[0013] Note: Automatic pressing is achieved by aligning the pressure plate with the mold box.

[0014] Furthermore, the ejector is equipped with a servo lifting motor, the output end of which is fixedly connected to the bottom of the top block.

[0015] Explanation: The high-alumina bricks pressed inside the mold box are ejected by an ejector.

[0016] Furthermore, the bottom of the mold box is provided with a T-shaped block, which engages with a T-shaped groove provided at the bottom of the mold box. After the T-shaped block engages with the T-shaped groove, the top of the T-shaped block is flush with the bottom of the mold box, and the bottom of the T-shaped block is connected to the top block.

[0017] Explanation: The high-alumina bricks are tightly pressed and ejected by the cooperation of T-blocks and T-slots.

[0018] Furthermore, a servo motor is provided on one side of the ejector, and a rotating shaft is provided at the output end of the servo motor. A connecting rod is provided at the end of the rotating shaft, and an arc-shaped locking block is provided at the end of the connecting rod. After the arc-shaped locking block rotates with the rotating shaft, it docks with and clamps the high-alumina brick pressed and formed inside the mold box ejected by the ejector.

[0019] Description: The high-alumina brick is clamped by a servo motor and transferred to the top of the second conveyor belt.

[0020] Furthermore, a second conveyor belt is provided on the other side of the servo rotating motor relative to the ejector, and a limiting baffle is provided above the second conveyor belt. After the bow-shaped block rotates with the rotating shaft, it docks with the limiting baffle and ejects the clamped high-alumina brick into the second conveyor belt.

[0021] Explanation: The high-alumina bricks held in the mold are blocked by a limiting baffle, causing them to fall onto the second conveyor belt for subsequent firing.

[0022] The beneficial effects of this utility model are:

[0023] This utility model discloses an integrated molding equipment for high-alumina bricks, which can realize the integrated process of raw material batching, mixing, feeding, pressing, ejection, transfer and conveying of high-alumina bricks. The whole process can be automated, easy to operate, and greatly saves manpower and material resources.

The upper end of the ejector 4 has a top block 41. After the top block 41 rises, it passes through the slot 32 and connects with the bottom of the mold box 5. The ejector 4 has a servo lifting motor 42 inside. The output end of the servo lifting motor 42 is fixedly connected to the bottom of the top block 41. The first conveyor belt 3 is a commercially available flexible chain conveyor. After improvement, the groove 31 and slot 32 unique to this utility model are obtained. The material of the first conveyor belt 3 is carbon steel.

[0033] The bottom of the mold box 5 is provided with a T-shaped block 51, which is engaged with the T-shaped groove 52 provided at the bottom of the mold box 5. After the T-shaped block 51 is engaged with the T-shaped groove 52, the top of the T-shaped block 51 is flush with the bottom of the mold box 5. The bottom of the T-shaped block 51 is connected to the top block 41.

[0037] Working principle:

[0038] The working principle of the integrated high-alumina brick molding equipment of this utility model will be briefly explained below.

[0039] Mixing: Place bauxite, soft clay, powder, and binder into mixer 1, and set aside for use after mixing;

[0040] Feeding: Start the first conveyor belt 3 and place the mold box 5 in the designated position inside the slot 32, so that the first conveyor belt 3 drives the mold box 5 to reciprocate. When the mold box 5 is below the feeding port 11, the mixer 1 feeds in the specified amount of material.

[0041] Pressing: Then the first conveyor belt 3 moves the mold box 5 to below the press machine 2, and the press machine 2 is turned on to lower the pressure plate 21 to press the material inside the mold box 2;

[0042] Ejection: After pressing 3 times, lift the pressure plate 21 and at the same time lift the top block 41 so that it aligns with the T-shaped block 51 at the bottom of the mold box. Continue to rise so that the T-shaped block 51 moves out of the T-shaped groove 52 and the pressed high-alumina brick is completely lifted out of the mold box 5.

[0043] Clamping: Turn on the servo rotating motor 6 to drive the rotating shaft 61 to rotate, and drive the bow-shaped clamping block 63 to move to the position of the high alumina brick through the connecting rod 62. Use one side of the bow-shaped clamping block 63 to clamp the high alumina brick and keep it stable under the action of friction.

[0044] Transfer: Continue to rotate the shaft 61 to make it rotate the high alumina brick to the top of the second conveyor belt 7, and the high alumina brick held by the limit baffle 71 will touch and fall onto the second conveyor belt 7 to complete the entire process.
