Description

Technical Field

[0001] This utility model relates to the field of refractory material processing technology, specifically to an automated production line for refractory materials. Background Technology

[0002] Refractory materials refer to inorganic non-metallic materials with a refractoriness of not less than 1580℃. Their physical and chemical properties allow them to be used in high-temperature environments. They are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing and other industrial fields. Refractory materials include silica bricks, high alumina bricks, magnesia bricks, castables, refractory mortar, fused zirconia-corundum bricks, etc.

[0003] Refractory bricks are a common type of refractory material. In the production process of refractory bricks, refractory castables and other ingredients need to be mixed evenly, then poured into molds for pressing and shaping, and then the shaped brick blanks are demolded and dried and fired.

[0004] Currently, most automated production involves mixing machines, molding machines, and conveyors. However, this requires multiple machines to be used in combination, resulting in a large footprint and gaps in material transfer, which reduces actual work efficiency and makes it difficult to achieve integrated production. Therefore, this application proposes an integrated production line for refractory brick production that combines mixing, pressing, and conveying. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes an automated production line for refractory materials.

[0006] The refractory material automated production line proposed in this utility model includes a workbench. The upper end of the workbench is equipped with a top frame via a column. The material cylinder and hydraulic press are both mounted on the top frame and can move horizontally. A pressing groove that runs vertically through the workbench is opened on the table surface, and the lower end of the pressing groove is sealed by a liftable pallet. The lower end of the workbench is equipped with a conveyor and a transverse pushing mechanism located on both sides of the pallet. When the pallet moves down to the lowest point, the transverse pushing mechanism pushes the brick blanks carried on the pallet onto the conveying section of the conveyor.

[0007] To address the issues of large footprint and low efficiency in traditional refractory brick production equipment, this design achieves integrated "feeding-pressing-conveying" through an integrated structure. The pressing trough and pallet form a closed pressing space. The pallet is driven by a lifting mechanism, rising to block the pressing trough during pressing and descending to be level with the conveyor after pressing. The lateral pushing mechanism pushes the brick blanks to the conveyor. The single cycle time is shorter, significantly improving efficiency compared to traditional multi-equipment combinations and reducing material transfer downtime.

[0008] Preferably, a horizontal displacement mechanism is installed on the top frame, and a movable seat is installed on the movable end of the horizontal displacement mechanism. The material cylinder and the hydraulic press are both installed on the movable seat and arranged adjacent to each other.

[0009] The horizontal displacement mechanism uses a servo motor to drive the ball screw, which moves the movable seat laterally along the top frame to achieve precise alignment between the material cylinder and the hydraulic press. For example, when feeding, it moves to the top of the pressing groove, and when pressing, the hydraulic press is aligned with the center of the pressing groove to ensure uniform pressing.

[0010] Preferably, the lower end of the material cylinder has a discharge port, and a discharge valve is installed at the discharge port. The discharge valve is a pneumatic butterfly valve, which can accurately control the discharge amount. Combined with the stirring function of the material cylinder, it ensures that the refractory material is discharged evenly, and avoids the density deviation of the brick blank caused by uneven discharge.

[0011] Preferably, the movable end of the hydraulic press extends downward and is equipped with a pressing plate, the pressing plate being adapted to the opening of the pressing groove;

[0012] The gap between the pressing plate and the pressing groove is small, and the hydraulic press provides pressing force to ensure uniform density of the brick blank. The surface of the pressing plate is quenched, with a hardness of HRC- and a high wear resistance life.

[0013] Preferably, a bracket for supporting the transverse pushing mechanism is installed inside the lower end of the worktable, and the upper surface of the bracket is flush with the conveying surface of the conveyor.

[0014] The support frame is welded with H-beams to ensure that the horizontal pushing mechanism is at the same height as the conveyor, thus avoiding damage caused by height difference when pushing brick blanks and reducing the brick blank breakage rate.

[0015] Preferably, a lifting mechanism is installed inside the lower end of the workbench, located between the conveyor and the transverse pushing mechanism. The pallet is installed on the upward-facing movable end of the lifting mechanism. When the pallet moves down to the lowest point, the upper surface of the pallet is flush with the conveying surface of the conveyor.

[0016] The lifting mechanism is driven by a hydraulic cylinder. When the pallet is lowered to the lowest position, it is flush with the conveyor surface, ensuring that the brick blanks are pushed smoothly and that the pressing groove is sealed.

[0017] Preferably, a push plate is installed on the movable end of the lateral push mechanism, and the push path of the lateral push mechanism is consistent with the conveying direction of the conveyor.

[0018] The pusher plate is made of rubber cushioning material, and the pushing speed is slow to avoid the brick blanks from hitting the edges and corners during pushing. The pushing path is consistent with the conveyor conveying direction to achieve seamless connection and conveying of brick blanks and improve the degree of automation.

[0019] Preferably, a sealing ring is installed at the bottom of the workbench surface, located around the lower opening of the pressing groove, and a sealing groove adapted to the sealing ring is opened on the upper surface of the pressing plate. When the pallet is moved to the highest position, the upper surface of the pallet fits against the bottom of the workbench surface, and the sealing ring and the sealing groove are seamlessly engaged.

[0020] The sealing ring is made of fluororubber, which is resistant to temperatures above ℃. It is interference-fitted with the sealing groove to form a sealed pressing space, preventing refractory material from overflowing, while ensuring uniform distribution of pressing pressure and improving the density consistency of the brick blank.

[0021] Preferably, the bottom of the workbench surface is provided with an annular groove located around the lower opening of the pressing groove, the upper end of the sealing ring is fixed in the annular groove, and the lower end of the sealing ring is interference-fitted with the sealing groove.

[0022] The annular groove is 5-8mm deep, and the interference fit between the lower end of the sealing ring and the sealing groove is 1-2mm to ensure no leakage during pressing. This sealing structure can withstand a pressing pressure of 10-20MPa and is suitable for the production of high-density refractory bricks.

[0023] The automated production line for refractory materials proposed in this utility model has the following beneficial effects:

[0024] (i) By integrating the workbench, material cylinder, hydraulic press, table pressing groove, pallet, conveyor and lateral pushing mechanism, the integrated production of "material feeding-pressing-conveying" is realized. After the material is pressed from the material cylinder through the pressing groove, the pallet descends to the lowest point and is pushed to the conveyor by the lateral pushing mechanism. This reduces manual intervention and material transfer gaps, and the production efficiency is greatly improved compared with the traditional multi-equipment combination, thereby increasing the capacity of the automated production line and improving the production efficiency of the enterprise.

[0025] (ii) The horizontal displacement mechanism of the top frame drives the material cylinder and hydraulic press to move horizontally and accurately align with the pressing groove. The pallet is driven by the lifting mechanism. During pressing, it rises to block the pressing groove and falls to the level of the conveyor after pressing. This design makes the positioning error between the pressing plate and the pressing groove smaller and the lifting time of the pallet shorter, so as to complete one pressing-conveying cycle in a short time. This speeds up the production rhythm compared with the traditional intermittent production and improves the actual production efficiency.

[0026] (iii) The sealing ring at the bottom of the workbench surface is interference-fitted with the sealing groove of the pressing plate. When the pallet is raised to the highest point, a sealed space is formed to prevent the refractory material from overflowing during pressing. It can also improve the uniformity of pressing pressure, improve the consistency of brick density, and thus improve the finished product qualification rate. It is especially suitable for the production of high-density refractory bricks.

[0027] (v) The pushing plate of the transverse pushing mechanism is aligned with the conveyor conveying direction. When the pallet descends to the lowest point, the pushing plate pushes the brick blank to the conveyor at a steady speed, avoiding edge and corner damage caused by traditional manual handling, thereby reducing the brick blank breakage rate and economic losses.

[0028] (vi) This automated production line integrates mixing, pressing and conveying functions, which greatly reduces the floor space required, thereby reducing equipment procurement costs. At the same time, the support frame makes the conveyor and the lateral pushing mechanism level, reducing space waste and making it suitable for the layout of workshops of small and medium-sized enterprises.

[0029] (vii) Horizontal displacement mechanism, lifting mechanism, etc. can be automatically controlled by PLC program to complete the "material feeding-pressing-conveying" process with one click, reducing human operation errors. When the equipment is maintained, the pallet, push plate and other components can be disassembled separately, thereby shortening the maintenance time and ensuring the continuous operation of the production line.

[0030] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] In the field of refractory material processing, traditional refractory brick production equipment suffers from problems such as large footprint and low production efficiency, making it difficult to meet the needs of integrated production. The automated refractory material production line provided by this utility model, through integrated design and automated control, realizes the integration of the entire process of refractory brick production, including "feeding-pressing-conveying". Its specific implementation method is as follows:

[0037] like Figures 1-3As shown, the production line is based on the workbench 1, with the top frame 3 supported by the column 2. The top frame 3 is equipped with a horizontally movable material cylinder 6 and a hydraulic press 7. The workbench 1 has a pressing groove 4 on its surface, and its lower end is blocked by a liftable pallet 5. The bottom of the workbench 1 integrates a conveyor 9 and a transverse pushing mechanism 11. Lifting mechanisms 12 are set on both sides of the pallet 5 to form a "pressing-conveying" linkage system. The horizontal displacement mechanism 14 of the top frame 3 drives the movable seat 15 to move, so as to achieve precise positioning of the material cylinder 6 and the hydraulic press 7.

[0038] like Figure 1 As shown, during material feeding, the horizontal displacement mechanism 14 drives the movable seat 15 to move the material cylinder 6 directly above the pressing groove 4, and opens the feeding valve 13. The refractory material falls evenly into the pressing groove 4. The material cylinder 6 has a built-in stirring structure to ensure that the material is mixed evenly. The feeding amount is precisely controlled by the pneumatic butterfly valve.

[0039] like Figure 2 As shown, during pressing, the hydraulic press 7 moves with the movable seat 15 to the top of the pressing groove 4, the pressing plate 8 is aligned with the pressing groove 4, the support plate 5 is driven to move upward by the lifting mechanism 12 and fits against the bottom of the workbench 1, the sealing ring 17 is embedded in the sealing groove 18 of the pressing plate 8 to form a sealed space, the hydraulic press 7 applies a pressure of 10-20MPa, and the pressing plate 8 presses the material into shape, and the density uniformity of the brick blank reaches more than 98%.

[0040] like Figure 2 and Figure 3 As shown, after pressing, the lifting mechanism 12 moves the pallet 5 down to the lowest point. At this time, the upper surface of the pallet 5 is flush with the conveying surface of the conveyor 9. The bracket 10 ensures that the horizontal pushing mechanism 11 is at the same height as the conveyor 9. The pushing plate 16 of the horizontal pushing mechanism 11 pushes the brick blank to the conveyor 9 at a speed of 0.5m / s. The pushing path is consistent with the conveying direction to avoid the brick blank from being bumped and broken. The conveyor 9 transports the brick blank to the subsequent drying process. The single cycle time is shortened by 40% compared with the traditional process.

[0041] like Figure 3 As shown, the fluororubber sealing ring 17 is fixed in the annular groove at the bottom of the workbench 1. The lower end of the sealing ring 17 is interference-fitted with the sealing groove 18 of the pressing plate 8, with an interference of 1-2mm. It can withstand a pressing pressure of 20MPa to prevent material overflow and ensure uniform brick density. The surface of the pressing plate 8 is hardened to a hardness of HRC55-60, and the gap between it and the pressing groove 4 is ≤0.1mm to ensure pressing accuracy and a service life of more than 5000 cycles.

[0042] In one embodiment, the horizontal displacement mechanism 14 uses a servo motor to drive the ball screw, with a positioning accuracy of ±0.5mm, enabling rapid switching between the material cylinder 6 and the hydraulic press 7, with a single movement time of ≤3 seconds. The lifting mechanism 12 uses a hydraulic cylinder to drive the pallet 5 to lift, with a speed adjustable from 0.1 to 0.5m / s. When the pallet 5 moves to the highest position, the contact error with the table surface is ≤0.3mm, ensuring the sealing of the pressing.

[0043] In one embodiment, after a refractory material plant applied this production line, its single-shift capacity increased from 800 bricks / shift to 1500 bricks / shift using the traditional process, improving efficiency by 87.5%. The density deviation of the brick blanks decreased from ±5% to ±2%, and the finished product qualification rate increased from 85% to 97%. It is particularly suitable for the production of high-density magnesia bricks and high-alumina bricks. Moreover, the integrated design reduces the equipment footprint by 60% compared to traditional multi-equipment combinations, making it suitable for the layout of small and medium-sized enterprise workshops. PLC automated control reduces human error, and components such as pallet 5 and push plate 16 can be disassembled individually, shortening the single maintenance time to 1 hour and reducing annual maintenance costs by 30%.

[0044] The production process is as follows:

[0045] S1 parameter settings: The pressing pressure is set to 15MPa, the pallet lifting speed is 0.3m / s, and the pushing plate moving speed is 0.5m / s via the PLC system;

[0046] S2 Automatic Cycling:

[0047] The horizontal displacement mechanism 14 moves the material cylinder 6 above the pressing groove 4, and the feeding valve 13 opens to feed the material.

[0048] The hydraulic press 7 moves above the pressing groove 4, the support plate 5 moves up to seal, and the pressing plate 8 presses down to form the shape. The pressing time is 20 seconds.

[0049] The pallet 5 descends to the height of the conveyor 9, and the transverse pushing mechanism 11 pushes the brick blank onto the conveyor 9, completing one cycle;

[0050] S3 Real-time Monitoring: The system monitors parameters such as pressing pressure and pallet position in real time. It automatically alarms and stops the machine when abnormalities occur to ensure production safety.

[0051] In summary, this production line, through the deep integration of mechanical structure and automated control, has achieved high efficiency, precision, and intelligence in refractory material production, providing a reliable solution for the technological upgrading of the refractory material industry.
