Description

Technical Field

[0001] This utility model relates to the technical field of refractory material molding equipment, specifically to an environmentally friendly molding equipment for recycled magnesia-carbon bricks. Background Technology

[0002] Magnesia-carbon bricks, as an important refractory material, are widely used in the linings of high-temperature equipment such as converters, electric furnaces, and ladles in the iron and steel metallurgical industry due to their excellent slag erosion resistance and high-temperature strength. They are mainly made of magnesia sand, carbon materials, and binders through processes such as mixing, molding, and heat treatment. With the increase in the consumption of refractory materials and the deepening of the concept of sustainable resource utilization, recycling and reusing waste magnesia-carbon bricks to prepare environmentally friendly recycled magnesia-carbon bricks has become an important development direction for the industry to reduce resource consumption and solid waste emissions.

[0003] Currently, the production of recycled magnesia-carbon bricks typically involves crushing, screening, and removing impurities (especially metal iron and other impurities that have seeped in during use) waste bricks, then mixing them with new raw materials in a certain proportion, and finally pressing them into shape. However, existing technologies lack efficient iron removal devices that are integrated with the molding process. If iron particles in the crushed raw materials cannot be effectively removed, it will seriously affect the high-temperature performance and service life of the recycled bricks. Secondly, the material is fed into the mold through a simple hopper during the molding process, which can easily lead to uneven distribution within the mold and affect the consistency of the green body density. In addition, traditional cold-pressing molding is followed by direct sintering in the kiln, resulting in high internal stress and low initial strength in the green body, making it prone to breakage during transportation and kiln loading. Utility Model Content

[0004] The purpose of this invention is to provide an environmentally friendly molding equipment for recycled magnesia-carbon bricks, which has the advantages of dispersed molding process, low iron removal efficiency, uneven material distribution, poor preheating effect of green body and insufficient automation, thus solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An environmentally friendly recycled magnesia-carbon brick forming device includes a support platform, a pressure forming mechanism fixed to the upper part of the support platform, a first moving mechanism set on the upper part of the support platform, a forming box placed on the upper part of the support platform, a heating mechanism set on the upper part of the support platform for heating the forming box, a bracket fixed to the upper part of the support platform, an upper frame fixed to the upper part of the side wall of the bracket, a lower frame fixed to the lower part of the side wall of the bracket, a magnetic suction frame slidably set between the upper frame and the lower frame, a feeding mechanism fixed to the lower end of the lower frame, a feeding mechanism set on the feeding mechanism, and a limiting mechanism set on the bracket for limiting the magnetic suction frame.

[0007] The first moving mechanism is used to move the molding box.

[0008] Preferably, a stop block for limiting and blocking the side wall of the molding box is fixedly connected to the upper end of the support platform, and a feed hopper is fixedly connected to the upper end of the upper frame.

[0009] It is worth noting that the stop can limit the movement of the forming box, and the feed hopper facilitates the entry of materials.

[0010] Preferably, the pressure forming mechanism includes two bearing blocks fixed to the upper end of the bearing platform, two columns fixed to the upper end of each bearing block, a bearing frame fixed to the upper end of the bearing platform, two first hydraulic cylinders fixed to the upper end of the bearing frame, a lifting plate fixed to the lower end of the output shaft of the two first hydraulic cylinders, a linear bearing fixed through the four corner edges of the upper end of the lifting plate, a pressure block fixed to the lower end of the lifting plate, and a first heating block fixed inside the pressure block. The inner wall of the linear bearing is in contact with the outer peripheral wall of the column.

[0011] It is worth noting that the first heating block fixed inside the pressing block can heat the pressing block during the pressing process, giving it a higher temperature. When the pressing block descends and applies pressure to the material in the forming box, heat is simultaneously transferred to the material, causing the binder (such as resin) in the material to soften and increase its fluidity. The material particles are easier to rearrange and compact. Compared with traditional cold pressing, this hot pressing process can obtain higher blank density and initial strength under the same pressure, while reducing the risk of blank cracking due to elastic aftereffects. The guide mechanism composed of linear bearings at the four corners and columns ensures that the lifting plate and pressing block make precise vertical movements under the drive of the hydraulic cylinder, preventing uneven load and ensuring the uniform transmission of pressing force and the uniformity of blank thickness.

[0012] Preferably, the first moving mechanism includes a first fixed seat and a first bearing seat fixed to the upper end of the support platform, a first lead screw rotatably installed between the first fixed seat and the first bearing seat, a first motor fixed to the side wall of the first fixed seat, a threaded sleeve block threaded to the outer peripheral wall of the first lead screw, and a connecting rod fixed to the end of the threaded sleeve block near the molding box, wherein the ends of the connecting rod and the molding box that are close to each other are fixedly connected to each other.

[0013] It is worth noting that the first moving mechanism achieves precise positioning and automatic transfer of the molding box on the support platform through screw transmission. The first motor drives the first screw to rotate, which in turn drives the threaded sleeve block and connecting rod that are threaded to it to move linearly along the screw axis, thereby pushing the molding box to move back and forth between the feeding station, the pressing station and the preheating station, which is convenient to use.

[0014] Preferably, the feeding mechanism includes a feeding cylinder fixed to the lower end of the lower frame, a distributing box fixed to the lower end of the feeding cylinder, a guide frame fixed to the lower end of the distributing box, and a plurality of discharge holes extending through the lower end of the distributing box.

[0015] It is worth noting that the material distribution box, as a transitional cavity, has multiple discharge holes at its lower end distributed along the length or width of the forming box. After the material enters the material distribution box from the feeding cylinder, it is temporarily contained and dispersed. When the material falls simultaneously through multiple discharge holes, multiple material streams are naturally formed, covering a wider area inside the forming box. Compared with a single large discharge port, this multi-hole discharge method can effectively reduce the "pile-up" phenomenon caused by material accumulation, making the initial distribution of material in the forming box more uniform and avoiding local over-thickness or under-thickness. The guide frame further constrains and guides the falling material stream to prevent material splashing. This structure lays an important foundation for obtaining brick blanks with uniform density distribution and solves the problem of uneven body density that is easily caused by traditional feeding methods.

[0016] Preferably, the feeding mechanism includes a second bearing seat and a second fixed seat fixed to one side of the feeding box, a second motor fixed to the side wall of the second fixed seat, a second lead screw rotatably mounted between the second bearing seat and the second fixed seat, a threaded sleeve threaded to the outer peripheral wall of the second lead screw, a slider fixed to the outer peripheral wall of the threaded sleeve, and a push block fixed to the lower end of the slider. The upper and lower end faces of the slider are slidably disposed between the upper and lower end faces of the inner wall of the groove, and the lower end of the push block is in contact with the bottom surface of the inner wall of the feeding box. The output shaft of the second motor is fixed to one end of the second lead screw.

[0017] It is worth noting that the material feeding mechanism works in conjunction with the material dispensing mechanism to achieve active, controllable, and uniform feeding of materials. The second motor drives the second lead screw to rotate, which in turn drives the threaded sleeve, slider, and pusher block to reciprocate along the bottom of the material distribution box. The bottom of the pusher block is in close contact with the bottom surface of the material distribution box. When it moves, it can effectively push the material accumulated below the inlet of the material distribution box to the surrounding areas and force the material to fall through each outlet hole. This process breaks the natural angle of repose of the material, preventing the material from forming arches or blockages in the material distribution box, and ensuring the continuity and smoothness of the feeding. Secondly, the reciprocating motion of the pusher block plays a role in forced material distribution and stirring, making the mixing of materials of different particle sizes more uniform, avoiding particle size segregation during the feeding process, and further optimizing the uniformity of material distribution.

[0018] Preferably, the limiting mechanism includes a limiting plate fixed to the bracket and a bearing plate fixed to the side wall of the lower frame. The upper end of the bearing plate is attached to the lower end of the magnetic frame, and the ends of the two limiting plates that are close to each other are respectively attached to the two sides of the magnetic frame. Ear plates are fixed to the side wall of the magnetic frame.

[0019] It is worth noting that the two limiting plates clamp the magnetic frame from the side, effectively restricting its movement or swaying in the horizontal plane. This ensures that the magnetic frame can be stably positioned in the predetermined space between the upper and lower frames during the power-on operation period, fixing the area covered by the magnetic field it generates. This guarantees the stability and consistency of the iron removal effect. The ear plates provide a leverage point for picking up and putting down the magnetic frame. When it is necessary to clean the adsorbed iron impurities, the operator can easily pull the entire magnetic frame out from the guide rail formed by the limiting plates between the upper and lower frames by lifting the ear plates. After cleaning, it can be pushed back along the original path and repositioned by the support plate.

[0020] Preferably, the heating mechanism includes two second heating blocks fixed to the upper end of the support platform, a groove opened on the upper end of the second heating blocks, a limiting block placed on the inner wall of the groove, and a third heating block fixed to the upper end of the two limiting blocks on the same side. The upper end of the third heating block is fixed with a handle, and the lower end of the third heating block is attached to the upper end of the second heating block. The two second heating blocks and the two third heating blocks are assembled to form a frame-shaped structure on the top surface.

[0021] It is worth noting that the second heating block is fixed to the support platform, forming the heating base. The third heating block is quickly positioned and installed by embedding its lower limiting block into the groove of the second heating block, and good heat conduction is achieved through the contact surface. The two second heating blocks and the two third heating blocks together form a frame structure with an open top. When the molding box containing the compacted material is sent into the frame structure by the first moving mechanism, the four side walls of the molding box will be heated from the outside by the four heating blocks at the same time. This circumferential heating method has high thermal efficiency and uniform heating, which can effectively promote the initial coking of the binder in the green body, improve the initial strength of the green body after demolding, and reduce the breakage rate before subsequent sintering. The handle design makes it easy to pick up and put down the third heating block. When it needs to be replaced or repaired, it can be quickly disassembled and assembled without tools.

[0022] Preferably, the lifting plate is provided with a temperature measuring mechanism, which includes a second oil cylinder fixed to the upper end of the lifting plate, a lifting block fixed to the lower end of the output shaft of the second oil cylinder, and a temperature sensor fixed to the end of the lifting block near the pressure block. The ends of the temperature sensor and the pressure block that are close to each other are in contact with each other.

[0023] It is worth noting that the temperature sensor is connected to the output end of the second hydraulic cylinder via a lifting block, which drives the temperature sensor to move up and down. When temperature measurement is required, the second hydraulic cylinder pushes the lifting block and the temperature sensor downward, ensuring that its measuring end is in close contact with the side wall of the pressure block or the designated temperature measuring point, thus ensuring the accuracy of the measurement. After the measurement is completed, the hydraulic cylinder can retract the sensor, detaching it from the pressure block to avoid interference during the pressing process. The advantage of this mechanism is that it can directly monitor the temperature of the pressure block body, which is more direct and reliable than monitoring the heating element or ambient temperature. This provides a precise basis for adjusting the working power of the first heating block, ensuring that the hot pressing process temperature remains stable within the optimal range. Secondly, automated temperature measurement avoids the safety risks, measurement errors, and inefficiencies associated with manual operation of handheld temperature measuring instruments.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. This utility model integrates functions such as online iron removal, uniform material distribution, hot pressing, preheating of the blank, and automated conveying through integrated design, forming a continuous and automatic process flow. After the material is uniformly distributed by the magnetic suction frame, the material distribution box, and the material feeding mechanism, the forming box is driven by the first moving mechanism to complete the hot pressing and surrounding preheating in sequence. This effectively solves the problems of low efficiency, dust pollution, and poor quality consistency caused by the dispersion of traditional processes and multiple material transfers.

[0026] 2. By setting up a magnetic suction frame in the material flow channel and using a limiting mechanism to ensure the stability of its working position, the online efficient adsorption and removal of iron particles in the raw materials is achieved, which improves the purity of the raw materials from the source and ensures the metallurgical performance and service life of the recycled bricks.

[0027] 3. By combining the dispersion of multiple discharge holes in the feeding mechanism with the forced pushing of the feeding mechanism, the material is filled into the molding box in a multi-stream uniform flow, which solves the technical problem of poor uniformity of blank density caused by uneven material distribution from the source.

[0028] 4. By embedding the first heating block into the pressing block, the hot pressing process is realized. During the pressing process, heat is simultaneously transferred to the material, which effectively reduces the frictional resistance between material particles and the viscosity of the binder, making the material easier to flow and compact rearrange. Thus, under the same pressure, a blank with higher density, greater initial strength and lower internal stress is obtained, which significantly reduces the breakage rate in subsequent processes.

[0029] 5. The heating mechanism adopts a combined frame structure, which can simultaneously heat the molding box fed into it from multiple sides in a surrounding manner. The heat field is uniform and the thermal efficiency is high, which effectively promotes the initial coking and solidification of the binder in the blank, and further improves the preheating effect and the overall strength of the blank after demolding.

[0041] To address the challenges of high integration, online iron removal, uniform material distribution, preheating, and improved production automation in existing technologies, the following technical solution is proposed. Please refer to [link / reference]. Figures 1-9 ;

[0042] Example 1: An environmentally friendly recycled magnesia-carbon brick forming device, comprising a support platform 1, a pressure forming mechanism 2 fixed to the upper end of the support platform 1, a first moving mechanism 3 set on the upper end of the support platform 1, a forming box 4 placed on the upper end of the support platform 1, a heating mechanism 5 set on the upper end of the support platform 1 for heating the forming box 4, a bracket 6 fixed to the upper end of the support platform 1, an upper frame 7 fixed to the upper part of the side wall of the bracket 6, a lower frame 8 fixed to the lower part of the side wall of the bracket 6, a magnetic suction frame 9 slidably disposed between the upper frame 7 and the lower frame 8, a feeding mechanism fixed to the lower end of the lower frame 8, a feeding mechanism set on the feeding mechanism, and a limiting mechanism set on the bracket 6 for limiting the magnetic suction frame 9.

[0043] The first moving mechanism 3 is used to move the molding box 4.

[0044] In use, the first moving mechanism 3 moves the molding box 4 below the feeding mechanism, and the material is put into the upper frame 7. The magnetic suction frame 9 is activated to attract the iron particles inside using magnetic force. The feeding mechanism is activated to move the material in the feeding mechanism. The material will fall into the molding box 4 through the lower frame 8 and the feeding mechanism. Then, the first moving mechanism 3 is activated to move the molding box 4 below the pressure molding mechanism 2. The pressure molding mechanism 2 can compact the material in the molding box 4. Then, the molding box 4 is moved to the heating mechanism 5 for heating, and the brick can be pre-formed.

[0045] In this embodiment, specifically: a stop block 24 for limiting and blocking the side wall of the molding box 4 is fixedly connected to the upper end of the support platform 1, and a feed hopper 13 is fixedly connected to the upper end of the upper frame 7.

[0046] In this embodiment, specifically: the pressure forming mechanism 2 includes two bearing blocks 201 fixed to the upper end of the bearing platform 1, two columns 202 fixed to the upper end of each bearing block 201, a bearing frame 203 fixed to the upper end of the bearing platform 1, two first oil cylinders 204 fixed to the upper end of the bearing frame 203, a lifting plate 205 fixed to the lower end of the output shaft of the two first oil cylinders 204, a linear bearing 206 fixed through the four corner edges of the upper end of the lifting plate 205, a pressure block 207 fixed to the lower end of the lifting plate 205, and a first heating block 208 fixed inside the pressure block 207.

[0048] In this embodiment, specifically: the feeding mechanism includes a feeding cylinder 15 fixed to the lower end of the lower frame 8, a distributing box 16 fixed to the lower end of the feeding cylinder 15, a guide frame 17 fixed to the lower end of the distributing box 16, and a plurality of discharge holes 19 through which the distributing box 16 is opened.

[0049] In this embodiment, specifically: the feeding mechanism includes a second bearing seat 28 and a second fixed seat 29 fixed to one side of the feeding box 16, a second motor 30 fixed to the side wall of the second fixed seat 29, a second lead screw 31 rotatably installed between the second bearing seat 28 and the second fixed seat 29, a threaded sleeve 32 threaded to the outer peripheral wall of the second lead screw 31, a slider 33 fixed to the outer peripheral wall of the threaded sleeve 32, and a push block 34 fixed to the lower end of the slider 33. The upper and lower end faces of the slider 33 are slidably disposed between the upper and lower end faces of the inner wall of the groove 18, and the lower end of the push block 34 is in contact with the bottom surface of the inner wall of the feeding box 16. The output shaft of the second motor 30 is fixed to one end of the second lead screw 31.

[0050] In this embodiment, specifically: the limiting mechanism includes a limiting plate 14 fixed to the bracket 6 and a bearing plate 21 fixed to the side wall of the lower frame 8. The upper end of the bearing plate 21 is attached to the lower end of the magnetic frame 9. The ends of the two limiting plates 14 that are close to each other are attached to the two sides of the magnetic frame 9 respectively. The side wall of the magnetic frame 9 is fixed with an ear plate 20.

[0051] In this embodiment, specifically: the heating mechanism 5 includes two second heating blocks 22 fixed to the upper end of the support platform 1, a groove 23 opened on the upper end of the second heating block 22, a limiting block 26 placed on the inner wall of the groove 23, and a third heating block 25 fixed to the upper end of the two limiting blocks 26 on the same side. The upper end of the third heating block 25 is fixed with a handle 27, and the lower end of the third heating block 25 is attached to the upper end of the second heating block 22. The two second heating blocks 22 and the two third heating blocks 25 are assembled to form a frame-shaped structure on the top surface.

[0052] Example 2: Based on Example 1, this example provides a technical solution, specifically: a temperature measuring mechanism is provided on the lifting plate 205. The temperature measuring mechanism includes a second oil cylinder 10 fixed to the upper end of the lifting plate 205, a lifting block 11 fixed to the lower end of the output shaft of the second oil cylinder 10, and a temperature sensor 12 fixed to one end of the lifting block 11 near the pressure block 207. The ends of the temperature sensor 12 and the pressure block 207 that are close to each other are in contact with each other.

[0053] Working principle: First, the operator puts the mixed recycled magnesia-carbon brick raw material into the equipment through the feed hopper 13. The raw material falls into the upper frame 7 fixed to the upper side wall of the support 6. At this time, the magnetic suction frame 9, which is slidably set between the upper frame 7 and the lower frame 8, is powered on. The magnetic field generated by the magnetic suction frame 9 adsorbs the iron particles in the falling raw material, thereby realizing online iron removal.

[0054] The raw material, after removing iron impurities, continues to fall and enters the distribution box 16 through the feeding cylinder 15 fixed to the lower end of the lower frame 8. At the same time, the feeding mechanism starts to work. The second motor 30 fixed to the side wall of the second fixed seat 29 starts and drives the second lead screw 31 to rotate, which drives the threaded sleeve 32, the slider 33, and the push block 34 fixed to the lower end of the slider 33 to reciprocate along the bottom of the distribution box 16. The push block 34 pushes the accumulated material to the surroundings and forces it to fall evenly through the multiple discharge holes 19 opened at the lower end of the distribution box 16. Guided by the guide frame 17, it is finally evenly distributed into the forming box 4 placed on the support platform 1.

[0055] After the fabric is completed, the first moving mechanism 3 is started. The first motor 303, which is fixed to the side wall of the first fixed seat 301, drives the first lead screw 304 to rotate, so that the threaded sleeve 305, which is threaded on the first lead screw 304, and the molding box 4, which is fixed to it through the connecting rod 306, move in a straight line, thereby accurately conveying the molding box 4 containing the material to the bottom of the pressure forming mechanism 2.

[0056] Subsequently, the pressure forming mechanism 2 starts to work. The two first oil cylinders 204 fixed to the upper end of the support frame 203 move synchronously. Their output shafts push the lifting plate 205 downward. The lifting plate 205 descends smoothly along the guide of the column 202 through the linear bearings 206 set at the four corners, driving the pressure block 207 fixed to its lower end to press into the forming box 4.

[0057] During this process, the first heating block 208 fixed inside the pressing block 207 is continuously heated to keep the pressing block 207 at a high temperature, thereby hot pressing the material in the forming box 4. In order to monitor the hot pressing temperature, the temperature measuring mechanism works synchronously. The second oil cylinder 10 fixed to the upper end of the lifting plate 205 pushes the lifting block 11 and the temperature measuring sensor 12 fixed thereon to move down, so that the temperature measuring sensor 12 is in close contact with the side of the pressing block 207 to measure the temperature. After the measurement is completed, it is retracted.

[0058] After the pressing process is completed, the first moving mechanism 3 is started again to transport the compacted blank together with the forming box 4 to the heating mechanism 5. The heating mechanism 5 consists of two second heating blocks 22 fixed to the upper end of the support platform 1 and two third heating blocks 25 placed in its groove 23 by the limiting block 26. Together they form a frame structure with an open top.

[0059] When the forming box 4 is sent into the frame structure, its four side walls are simultaneously preheated from the outside by the second heating block 22 and the third heating block 25, thereby completing the preforming of the brick blank. Throughout the process, the magnetic frame 9 is supported by the bearing plate 21 fixed to the side wall of the lower frame 8, and is limited from both sides by the two limiting plates 14 fixed to the bracket 6 to ensure its working position is stable.

[0060] The stop block 24 at the upper end of the support platform 1 limits and blocks the lateral movement of the forming box 4. Through the sequential and coordinated actions of the above mechanisms, this utility model realizes fully automatic and continuous production from raw material iron removal, uniform material distribution, hot pressing and forming to blank preheating.
