Description

Technical Field

[0001] This application relates to the technical field of refractory brick production equipment, and particularly to a refractory brick filling and forming equipment and method. Background Art

[0002] Refractory bricks are materials that can withstand high temperatures. According to their composition and uses, refractory bricks are mainly divided into two categories: shaped refractory bricks and unshaped refractory bricks. Shaped refractory bricks include common clay bricks, high-aluminum bricks, mullite bricks, corundum bricks, etc. These bricks can maintain stable physical and chemical properties in high-temperature environments; while unshaped refractory bricks include refractory mud, refractory castables, etc. They usually exist in the form of powders or slurries and need to be prepared and constructed according to specific requirements when in use.

[0003] During the production of refractory bricks, the mixed refractory materials are pressed into bricks with specific shapes and sizes to lay the foundation for subsequent sintering and the performance of the final product. The pressing process usually includes the following main steps: filling, pressing into shape, ejecting, and finishing.

[0004] For example, a refractory brick automatic filling and forming device with the application number CN202310972934.0, which relates to the technical field of refractory brick production equipment. In this prior art, there is a pressing platform with a pressing cavity. A bottom plate is slidably connected in the pressing cavity. An upward lifting hole is opened at the bottom of the pressing cavity, and a contact plate is fixedly provided at the bottom of the bottom plate; a downward pressing frame is erected on the pressing platform; a telescopic cylinder is installed on the downward pressing frame and is equipped with a pressing plate; a feeding device is located on one side of the pressing platform; a pushing cylinder is located on one side of the pressing platform, connected to a mounting plate. The top of the mounting plate is fixedly connected with a top frame for receiving the raw materials of the feeding device and sending them into the pressing cavity, and the bottom is fixedly connected with a push rod for ejecting the refractory bricks.

[0005] However, there are still some defects in the above prior art when pressing refractory bricks into shape: When the above prior art presses refractory bricks into shape, the material hole is close to the storage tank at the inner bottom wall of the brick unloading plate. The storage tank fills the raw materials into the empty part of the pressing cavity and levels them to achieve the filling of the raw materials in the pressing cavity. In this process, the raw materials are filled into the pressing cavity by gravity. Generally, the raw materials of unshaped refractory bricks are in powder form, and the raw materials will inevitably form a tower-shaped accumulation. This tower-shaped accumulation results in uneven distribution of the raw materials in the pressing cavity. The raw material density in the central area is relatively high, while the raw material density in the edge area is relatively low. The leveling process cannot change the distribution state of the raw materials in the pressing cavity. Therefore, there are still significant differences in the raw material density in different areas of the pressing cavity, with a high density in the central area and a low density in the edge area.

[0006] Due to the uneven distribution of raw materials in the pressing cavity, the pressing pressures on the raw materials in different regions during the pressing process are also different. In the central region, due to the high density of the raw materials, the pressure received is relatively large, while in the edge region, due to the low density of the raw materials, the pressure received is relatively small. The uneven pressing pressure will lead to inconsistent density and strength of the refractory brick, affecting the quality and service performance of the product.

[0007] At the same time, the above-mentioned existing technology drives the pressing plate to press and form the raw materials through the telescopic cylinder. That is to say, the pressing plate completes the pressing of the raw materials from one side downward. Since the pressing force is applied only from one side, the refractory brick may bend during the pressing process, resulting in an irregular product shape. The uneven pressure distribution will cause stress concentration inside the refractory brick, increasing the risk of internal cracks and defects in the product. This deformation and stress concentration will affect the dimensional accuracy and mechanical properties of the refractory brick, reducing the qualified rate and service reliability of the product.

[0008] Based on this, under the statement of the above viewpoints, there is still room for improvement in the way of pressing and forming refractory bricks in the existing technology. Summary of the Invention

[0018] In a second aspect, a method for forming refractory brick filler, its usage method includes the following steps: S1: Pressing preparation, when pressing and forming refractory bricks, first quantitatively fill raw materials into the storage bin, and then start the driver to drive the sliding strips on both sides of the bottom plate to move downward; S2: Pressing down the raw materials, at this time, the two sliding strips drive the sliding plate to move downward together, the lower end of the pressing frame abuts against the upper end of the storage bin, the sliding strips continue to drive the sliding plate to move downward, the sliding strips move downward along the sliding grooves, and drive the pressing rod to compress the pressing spring at the same time; S3: Compaction treatment, during this process, the raw materials are compacted, the lower pressing plate pushes the upper top plate through the compacted raw materials, so that the upper top plate moves downward and drives the sliding rod; S4: Double-sided pressing, when the raw materials are compacted, the compacted raw materials push the upper top plate to move downward, the downward movement of the upper top plate compresses the return spring, and an upward force is applied to the raw materials through the upper top plate, cooperating with the lower pressing plate to realize double-sided pressing of the raw materials; S5: Pressure adjustment, by rotating the threaded connection between the adjustment ring and the adjustment rod, forcing the sliding rod to drive the upper top plate to move, and changing the pressure of the return spring, so as to change the pressing time and strength of the raw materials.

When the resistance of the lower pressing plate of the present invention reaches the set value, the compacted raw materials will push the upper top plate to move downward, and the downward movement of the upper top plate will compress the return spring arranged between the adjustment plate and the upper top plate. Since the return spring is compressed, the return spring will generate an upward thrust, and an upward force is applied to the raw materials through the upper top plate, cooperating with the lower pressing plate to realize double-sided pressing of the raw materials. Through the pressing forces in the upper and lower directions, it can ensure that the raw materials are evenly compacted in the storage bin, improving the density and strength of the refractory bricks.

[0019] 2. By rotating the adjusting rod, the adjusting rod drives the adjusting plate to move through the threaded connection with the bottom of the bin, thereby changing the elastic force of the return spring, and then changing the upward pressure on the raw material. By rotating the threaded connection between the adjusting ring and the adjusting rod, the sliding rod is forced to drive the upper top plate to move and change the pressure of the return spring, thereby changing the pressing time and strength of the raw material.

The vibration reduces the friction between the raw material particles, making the particles easier to move and rearrange, thereby reducing local accumulation and voids.

Detailed implementation manners

[0030] The following Figures 1 to 10 further elaborates on this application.

[0031] The embodiment of this application discloses a refractory brick filler forming device and method. By vibrating the raw materials, the friction between the raw material particles is reduced, making the particles easier to move and rearrange, thereby reducing local accumulation and voids. Two-way compaction is adopted to achieve a more uniform compaction effect and avoid the problem of uneven pressure caused by single-sided compaction.

[0032] Embodiment 1: Referring to Figure 1 shown, a refractory brick filler forming device includes a bottom plate 1, and a silo 2 is arranged on the bottom plate 1.

[0033] When compacting and forming refractory bricks, first, the raw materials are filled into the silo 2 through an existing metering device, and then the driver 6 arranged on the silo 2 is started. The driver 6 will drive the symmetrically arranged sliding bars 3 on both sides of the bottom plate 1 to move downward. The movement of the sliding bars 3 will trigger the two-way press 4 arranged between the two sliding bars 3. The two-way press 4 presses into the silo 2 and presses the raw materials in the silo 2 from the upper and lower directions, which can achieve a more uniform compaction effect and avoid the problem of uneven pressure caused by single-sided compaction.

[0034] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, specifically, the two-way press 4 includes a sliding plate 41 commonly arranged between the two sliding bars 3. A lower pressing frame 42 located directly above the silo 2 is slidably arranged on the sliding plate 41. Symmetric sliding grooves 421 corresponding to the sliding bars 3 one by one are opened on both sides of the lower pressing frame 42. A lower partition 422 is arranged at the lower end of the lower pressing frame 42. When the refractory bricks are pressed into shape, the driver 6 will drive the two sliding bars 3 to move downward. At this time, the two sliding bars 3 will drive the sliding plate 41 to move downward together, and the lower pressing frame 42 will move downward together. The lower end of the lower pressing frame 42 will abut against the upper end of the silo 2. Then the sliding bar 3 will continue to drive the sliding plate 41 to move downward. The sliding bar 3 will move downward along the sliding groove 421 and drive the pressing rod 43 arranged on the sliding plate 41. At the same time, it will compress the pressing spring 45 arranged between the sliding plate 41 and the lower partition plate 422, and the pressing spring 45 is sleeved on the pressing rod 43.

[0035] Guide rods 441 are symmetrically arranged at the upper end of the lower pressing plate 44. The upper ends of the guide rods 441 penetrate through the lower partition plate 422. The guide rods 441 provide a guiding function. Through the guiding of the guide rods 441 and the force transmission of the pressing rod 43, the precision of the pressing process can be effectively improved, ensuring that the product sizes and densities of each pressing are consistent.

[0036] After the lower end of the pressing rod 43 slides through the lower partition plate 422, a lower pressing plate 44 is arranged, and the lower pressing plate 44 is located directly above the raw materials in the silo 2 within the lower pressing frame 42. The lower pressing plate 44 will move into the silo 2 and press on the raw materials until the lower pressing plate 44 is in place for pressing.

[0037] Refer to Figure 4 、 Figure 5 and Figure 6 As shown, during this process, the raw materials will be gradually compacted. When the raw materials are compacted to a certain extent, the lower pressing plate 44 will push the upper top plate 46 slidably arranged in the silo 2 through the compacted raw materials, causing the upper top plate 46 to move downward and drive the sliding rods 461 symmetrically arranged at the lower end of the upper top plate 46. The lower ends of the sliding rods 461 slide through to the lower end of the silo 2.

[0038] An adjusting plate 47 is slidably arranged in the silo 2 at the lower end of the upper top plate 46. When the raw materials are compacted to a certain extent, the resistance of the lower pressing plate 44 reaches the set value. The compacted raw materials will push the upper top plate 46 downward. The downward movement of the upper top plate 46 will compress the reset spring 471 arranged between the adjusting plate 47 and the upper top plate 46. Since the reset spring 471 is compressed, the reset spring 471 will generate an upward thrust, applying an upward force to the raw materials through the upper top plate 46, and cooperating with the lower pressing plate 44 to achieve double-sided pressing of the raw materials. Through the pressing forces in the upper and lower directions, it can be ensured that the raw materials are evenly compacted in the silo 2, improving the density and strength of the refractory bricks.

[0039] After the pressing is completed, the driver 6 drives the two sliding bars 3 to move upward. At this time, the sliding plate 41 drives the lower pressing plate 44 to move upward through the pressing rod 43. The lower pressing spring 45 will gradually release, and the compressed return spring 471 will gradually release, pushing the upper top plate 46 upward, pushing the compacted refractory brick upward until the upper top plate 46 reaches the limit position. After that, the lower pressing plate 44 continues to move upward to exit the bin 2, and then the two sliding bars 3 drive the lower pressing frame 42 to move upward to the initial position.

[0040] Referring to Figure 7 As shown, a receiving hole 5 is provided in the sliding rod 461, and an electric push rod 51 is arranged in the receiving hole 5. The telescopic end of the electric push rod 51 slides through the upper top plate 46 and is provided with a push plate 52. After the lower pressing frame 42 moves upward to the initial position, the telescopic end of the electric push rod 51 extends, driving the push plate 52 located at the upper end of the upper top plate 46 to rise. The push plate 52 ejects the pressed refractory brick from the bin 2 and then takes it away through the existing material taking equipment. Subsequently, the telescopic end of the electric push rod 51 drives the push plate 52 to retract, so that the push plate 52 is embedded in the upper top plate 46 and is flush with its upper surface.

[0041] Looking back at Figure 4 and Figure 5 As shown, in addition, an adjusting rod 48 is threaded through the bottom of the bin 2, and the upper end of the adjusting rod 48 is rotatably connected to the adjusting plate 47. Rotating the adjusting rod 48 causes the adjusting rod 48 to drive the adjusting plate 47 to move through the threaded connection with the bottom of the bin 2, so as to change the elastic force of the return spring 471, thereby changing the upward pressure on the raw material.

[0042] When the adjusting rod 48 is rotated to drive the adjusting plate 47 to move upward, the return spring 471 is compressed to increase the pressure on the upper top plate 46; conversely, when the adjusting rod 48 is rotated to drive the adjusting plate 47 to move downward, the return spring 471 is released to reduce the pressure on the upper top plate 46.

[0043] At the same time, an adjusting ring 49 (shown in Figure 6 ) is threaded on the sliding rod 461 at the lower end of the bin 2. By rotating the threaded connection between the adjusting ring 49 and the adjusting rod 48, the sliding rod 461 is forced to drive the upper top plate 46 to move, and the pressure of the return spring 471 is changed, thereby changing the pressing time and strength of the raw material.

[0044] When the adjusting ring 49 is rotated to move the upper top plate 46 downward, thereby compressing the return spring 471, and at the same time making the lower pressing plate 44 move downward to contact the raw material for a longer time, this means that the pressing time of the raw material is shorter and the pressing strength is smaller; conversely, when the adjusting ring 49 is rotated to move the upper top plate 46 upward, the return spring 471 is released, shortening the time for the lower pressing plate 44 to contact the raw material, thereby increasing the pressing time and strength.

[0045] Refer to Figure 8 As shown, specifically, the driver 6 includes drive shafts 61 rotatably arranged on both sides of the bin 2 through brackets. A drive gear 62 is arranged on the drive shaft 61, and a rack segment 63 meshing with the drive gear 62 is arranged on the sliding bar 3. A transmission shaft 64 corresponding to the drive shaft 61 one by one is rotatably arranged on the bin 2, and meshing transmission gears 65 are arranged on the two transmission shafts 64.

[0046] By driving one of the drive shafts 61 to rotate through a servo motor, the rotating drive shaft 61 will drive the driven gear 66 arranged on the drive shaft 61 to rotate. The driven gears 66 are respectively meshed with the corresponding transmission gears 65, so as to drive the transmission shaft 64 to transmit. The two transmission shafts 64 are provided with meshing and reverse rotations, and drive the two driven gears 66 to drive the two drive shafts 61 to rotate in the opposite direction. At this time, the drive shaft 61 will drive the drive gear 62 to rotate, and force the sliding bar 3 to move through the meshing of the drive gear 62 and the rack segment 63, so as to realize the pressing of the raw material.

[0047] Embodiment 2: Refer to Figure 9 and Figure 10 As shown, on the basis of Embodiment 1, the raw material of the unshaped refractory brick is usually powdery, and its fluidity is poor. During the pressing process of the double-sided press 4, the powdery raw material may have local accumulation or voids, resulting in uneven pressing density. Even in the case of double-sided pressing, the powdery raw material may still form a tower-shaped accumulation, especially in the central area of the bin 2, which will affect the uniformity of the pressing and forming.

[0048] By the vibrating member 7 slidably arranged on the bin 2, the bin 2 is vibrated during the pressing process. Through the action of the vibration force, the fluidity of the powdery raw material is improved. The vibration reduces the friction force between the raw material particles, and the particles are more likely to move and rearrange, thereby reducing local accumulation and voids.

[0049] Specifically, the vibrating member 7 includes a connecting frame 71 slidably arranged on the bin 2. The connecting frame 71 is in a U shape, with a horizontal section 72 and two vertical sections 73, and a rack 74 is arranged at the upper end of the vertical section 73 of the connecting frame 71.

[0050] When the drive shaft 61 is driven to rotate through a servo motor, the two transmission shafts 64 will rotate in the opposite direction to drive the incomplete gears 75 arranged thereon to rotate. The incomplete gears 75 will force the rack 74 to move downward through the meshing with the rack 74, and drive the connecting frame 71 to move downward. Since the horizontal section 72 of the connecting frame 71 is located between the adjusting ring 49 and the bottom of the bin 2, the connecting frame 71 will drive the sliding rod 461 through the adjusting ring 49 to move the upper top plate 46 downward and compress the return spring 471.

[0051] When the incomplete gear 75 disengages from the engagement with the rack 74, the compressed return spring 471 will move upward through the upper top plate 46 and drive the adjusting ring 49 upward through the sliding rod 461, forcing the connecting frame 71 to reset. The intermittent engagement and disengagement of the incomplete gear 75 and the rack 74 form a continuous vibration cycle.

[0052] The up-and-down displacement of the upper top plate 46 generates a vibration effect to improve the fluidity of the raw materials. This vibration will continue until the compacted raw materials push the upper top plate 46 downward. At this time, due to the downward movement of the upper top plate 46, the sliding rod 461 drives the adjusting ring 49 to move downward together, so that the return spring 471 no longer provides the reset elastic force to the connecting frame 71, thereby realizing the automatic stop of the vibration cycle, avoiding the influence of excessive vibration on the pressing quality. The uniform distribution of the raw materials also improves the quality of the compression molding and reduces the rejection rate.

[0053] Finally, the present invention also provides a method for forming refractory brick fillers, and its usage method includes the following steps: S1: Pressing preparation. When pressing and forming refractory bricks, first quantitatively fill the raw materials into the feed bin 2, and then start the driver 6 provided on the feed bin 2. The driver 6 will drive the sliding strips 3 symmetrically arranged on both sides of the bottom plate 1 to move downward.

[0054] S2: Pressing down the raw materials. At this time, the two sliding strips 3 will drive the sliding plate 41 to move downward together, and the pressing frame 42 will move downward together. The lower end of the pressing frame 42 will abut against the upper end of the feed bin 2. Then the sliding strip 3 continues to drive the sliding plate 41 to move downward. The sliding strip 3 will move downward along the sliding groove 421 and drive the pressing rod 43 provided on the sliding plate 41, and at the same time compress the pressing spring 45 provided between the sliding plate 41 and the lower partition plate 422.

[0055] S3: Compaction treatment. During this process, the raw materials will be gradually compacted. When the raw materials are compacted to a certain extent, the lower pressing plate 44 will push the upper top plate 46 slidably arranged in the feed bin 2 through the compacted raw materials, so that the upper top plate 46 moves downward and drives the sliding rods 461 symmetrically arranged at the lower end of the upper top plate 46.

[0056] S4: Double-sided pressing. When the raw materials are compacted to a certain extent, the resistance of the lower pressing plate 44 reaches the set value, and the compacted raw materials will push the upper top plate 46 downward. The downward movement of the upper top plate 46 will compress the return spring 471 provided between the adjusting plate 47 and the upper top plate 46. Since the return spring 471 is compressed, the return spring 471 will generate an upward thrust force, apply an upward force to the raw materials through the upper top plate 46, and cooperate with the lower pressing plate 44 to realize the double-sided pressing of the raw materials. Through the pressing forces in the upper and lower directions, it can ensure that the raw materials are evenly compacted in the feed bin 2, improving the density and strength of the refractory bricks.

[0057] S5: Pressure adjustment. By rotating the threaded connection between the adjusting ring 49 and the adjusting rod 48, the sliding rod 461 is forced to drive the upper top plate 46 to move, and the pressure of the return spring 471 is changed, thereby changing the pressing time and strength of the raw material.

[0058] S6: Vibration dispersion. The incomplete gear 75 will force the rack 74 to move downward through meshing with the rack 74, and drive the connecting frame 71 to move downward. Since the horizontal section 72 of the connecting frame 71 is located between the adjusting ring 49 and the bottom of the bin 2, the connecting frame 71 will drive the sliding rod 461 through the adjusting ring 49 to move the upper top plate 46 downward and compress the return spring 471.

[0059] When the incomplete gear 75 disengages from the meshing with the rack 74, the compressed return spring 471 will move upward through the upper top plate 46, and drive the adjusting ring 49 to move upward through the sliding rod 461, forcing the connecting frame 71 to reset. The intermittent meshing and disengagement of the incomplete gear 75 and the rack 74 form a continuous vibration cycle.

[0060] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.

A refractory brick filling forming device according to claim 8, characterized in that: The silo (2) is rotatably provided with transmission shafts (64) corresponding one to one with the drive shafts (61); the two transmission shafts (64) are provided with mutually meshing transmission gears (65); and the drive shafts (61) are provided with driven gears (66) respectively meshing with the corresponding transmission gears (65).

10. A method for forming a refractory brick filler, using a refractory brick filler forming device as claimed in any one of claims 1 to 9, characterized in that: The method of use includes the following steps: S1: Pressing preparation. When the refractory bricks are pressed and formed, firstly, the raw materials are quantitatively filled into the silo (2), and then the drive (6) is started to drive the sliding bars (3) on both sides of the bottom plate (1) to move downward; S2: Pressing the raw material downward, at this time, the two sliding bars (3) drive the sliding plate (41) to move downward together, the lower end of the pressing frame (42) contacts the upper end of the bin (2), the sliding bar (3) continues to drive the sliding plate (41) to move downward, the sliding bar (3) moves downward along the sliding groove (421), and drives the pressing rod (43) to compress the pressing spring (45) at the same time; S3: compaction process, during which the raw material is compacted, and the lower pressing plate (44) pushes the upper top plate (46) through the compacted raw material, so that the upper top plate (46) moves downward and drives the sliding rod (461); S4: Bidirectional pressing. When the raw material is compacted, the compacted raw material pushes the upper top plate (46) to move downward. The downward movement of the upper top plate (46) compresses the return spring (471), and an upward force is applied to the raw material through the upper top plate (46), thereby cooperating with the lower pressing plate (44) to achieve bidirectional pressing of the raw material. S5: Pressure adjustment, by rotating the adjusting ring (49) and the threaded connection of the adjusting rod (48), the sliding rod (461) is forced to drive the upper plate (46) to move, and the pressure of the return spring (471) is changed, thereby changing the time and intensity of the raw material being pressed.
