Abstract
Description
Technical Field
[0001] This utility model relates to the field of alkali-resistant brick forming technology, specifically to an automatic material feeding device for forming low-porosity alkali-resistant bricks. Background Technology
[0002] Alkali-resistant bricks are a type of refractory material commonly used in alkaline media environments such as kiln linings and high-temperature reaction equipment. They have strong corrosion resistance and good thermal stability and are widely used in industries such as metallurgy, building materials, and chemicals. The molding quality directly affects the subsequent sintering effect and performance. The structural components used in the molding process have a significant impact on molding efficiency and product quality.
[0003] Existing alkali-resistant brick molding equipment generally uses a method of mixing alkali-resistant brick raw materials and directly conveying them into the mold for shaping. However, this method has certain defects in the material handling process: First, it lacks compaction methods. The traditional method of directly outputting materials for molding not only easily causes problems such as loose materials and uneven density in the mold, but also affects the structural stability and service life of the alkali-resistant bricks. Second, when the material enters the mold, it is always in a flowing state. Traditional technology lacks the ability to disturb or adjust it, which leads to the presence of voids or stress concentrations in the molded products, resulting in poor quality of the finished alkali-resistant bricks. Utility Model Content
[0004] The purpose of this invention is to provide an automatic material feeding device for forming low-porosity alkali-resistant bricks, in order to solve the problem mentioned in the background art that the traditional alkali-resistant brick forming process lacks compaction and disturbance measures, resulting in poor finished product quality.

[0008] Preferably, the bottom of the metering cylinder has a discharge port, the size of which is adapted to the size of each pair of the multiple partition plates. A positioning plate is fixedly connected to one side of the bottom of the metering cylinder. When the model box is placed on top of the conveyor belt, it is located at the bottom of the output end of the positioning plate. The position of the discharge port corresponds to the position of the positioning plate, and in the initial state of the multiple partition plates, the position between two of the partition plates corresponds to the position of the discharge port.
[0009] Preferably, two fixing boxes are installed on the outside of the conveyor belt, a fixing frame is installed on one side of the fixing box, a guide rod is slidably connected to one end of the top of the fixing frame, a fixing plate is fixedly connected to the fixing frame on the side of the top of the conveyor belt, and the bottom of the guide rod passes through the inside of the fixing plate and is fixedly connected to the top of the compaction plate.
[0010] Preferably, a fixing ring is fixedly connected to the outside of the top of the fixing plate of the guide rod, a first spring is fixedly connected to the top of the fixing ring, the inside of the first spring is sleeved on the outside of the top of the guide rod, the top of the first spring is fixedly connected to the top of the fixing frame, and a compaction plate is fixedly connected to one end of the guide rod that passes through the top of the fixing frame.
[0011] Preferably, the bottom of the compaction plate has two arc-shaped openings on both sides, an arc-shaped block is fixedly connected to one side of the model box, a limit block is fixedly connected to one side of the arc-shaped block, a guide plate is fixedly connected to the top of one end of the fixed box, a limit groove is opened on the top of the guide plate, the end of the limit block away from the arc-shaped block is slidably connected to the inside of the limit groove, when the limit block slides inside the limit groove, the position of the model box corresponds to the position of the compaction plate, and the length of the guide plate is greater than the length of the compaction plate from the initial end of the conveyor belt.
[0012] Preferably, the distance between two adjacent push plates is greater than the width of the model box. The push plates are fixedly connected to a plurality of connecting cylinders on one side of the model box. A second spring is installed inside the connecting cylinder. A retractable rod is slidably engaged inside one end of the connecting cylinder. One end of the second spring is fixedly connected to one end of the retractable rod.
[0013] Preferably, a baffle plate is fixedly connected to the top of the fixed box at the end away from the guide plate. Multiple grooves are equally spaced on one side of the baffle plate. The size of the grooves is larger than that of the arc-shaped block. The baffle plate is located behind the compaction plate. The height of the top of the baffle plate is lower than the bottom of the limiting groove, and one end of the limiting groove passes through one end of the guide plate.
[0014] Preferably, a positioning post is fixedly connected to one side of the fixed box corresponding to the groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting the molding components, the mold box can achieve preliminary compaction under the pressing action of the compaction plate after the material is loaded. This structural design can significantly improve the pre-compaction density of the brick material, help reduce the porosity during the molding process, and thus improve the mechanical properties and density of alkali-resistant bricks.
[0016] Meanwhile, multiple push plates work in conjunction with the model box to push the bricks forward during the transmission process. When the model box moves past the bottom of the compaction plate, the elastic retraction between the connecting cylinder and the shrinking rod allows the push plates to flexibly adapt to the back-and-forth movement of the model box, further promoting the uniform distribution of materials within the model box and avoiding localized empty corners, layering, or uneven density caused by static material distribution.
[0017] Meanwhile, as the material inside the mold box is compacted and continues to move to the position between the buffer cylinder and the baffle, due to the multiple grooves on one side of the baffle and the arc-shaped block on one side of the mold box, the mold box will sway slightly from side to side as it slides through the groove area. This structure cleverly utilizes the cooperation between the grooves and the arc-shaped block to make the mold box sway without the need for an additional power structure, thereby promoting a small amount of self-flow and rearrangement of the material in the mold cavity, making the brick structure more uniform and compact, and significantly reducing the porosity.
[0018] By setting up a quantitative component, a quantitative cylinder is set at the bottom of the discharge cylinder, which has a connecting shaft and multiple ring-shaped equidistant fixed partition plates inside, forming several quantitative cavities, realizing the single quantitative output of materials. Due to the limitation of the spacing between the partition plates and the control of the motor, excessive material accumulation can be avoided, the amount of material supplied per unit time can be controlled, and the consistency of raw materials before each alkali-resistant brick is formed can be significantly improved.

[0029] Example 1
[0030] Please see Figures 1-6 This utility model provides an embodiment of an automatic material feeding device for forming low-porosity alkali-resistant bricks, comprising a feeding cylinder 1 and a conveyor belt 2. The conveyor belt 2 is located at the bottom of the output end of the feeding cylinder 1. The bottom of the feeding cylinder 1 is connected to an outlet cylinder 3. The bottom of the outlet cylinder 3 is provided with a metering component for quantitatively distributing the material. The metering component includes a metering cylinder 4 connected to the bottom of the outlet cylinder 3. A connecting shaft 10 is rotatably connected inside the metering cylinder 4. Multiple partition plates 11 are fixedly connected in a ring at equal intervals outside the connecting shaft 10. The top of the conveyor belt 2 is provided with a mechanism for automatically compacting and shaking the material to form a uniform shape. The molding assembly includes a mold box 14 placed on top of the conveyor belt 2, multiple push plates 24 fixedly connected to the top of the conveyor belt 2, and a compaction plate 21 installed on top of the conveyor belt 2. The size of the compaction plate 21 is adapted to the size of the opening at the top of the mold box 14. Through the molding assembly, the mold box 14 can achieve preliminary compaction under the pressure of the compaction plate 21 after the material is loaded. This structural design can significantly improve the pre-compaction density of the brick material, help reduce the porosity during the molding process, and thus improve the mechanical properties and density of the alkali-resistant brick.
[0031] The discharge cylinder 3 is rotatably connected to a rotating paddle 8. A first motor 6 is fixedly connected to one side of the discharge cylinder 3. The output end of the first motor 6 passes through one end of the discharge cylinder 3 and is fixedly connected to one end of the rotating paddle 8. The bottom of the discharge cylinder 3 has a discharge port 9 that is connected to the top of the metering cylinder 4. By setting the rotating paddle 8, the raw materials after mixing multiple alkali-resistant brick raw materials are first placed inside the discharge cylinder 1. Then, by starting the first motor 6, the rotation of the rotating paddle 8 is controlled, causing the rotating paddle 8 to output the material inside the discharge cylinder 1 evenly. This achieves automatic control of the material output and also avoids the problem of excessive load on the bottom receiving structure due to excessive output at one time, which could lead to damage.
[0032] The spacing between any two of the multiple partition plates 11 is greater than the size of the discharge port 9. A second motor 7 is fixedly connected to the bottom of the metering cylinder 4. The output end of the second motor 7 passes through the bottom of the metering cylinder 4 and is fixedly connected to the bottom of the connecting shaft 10. In the initial state, the position between two of the partition plates 11 corresponds to the position of the discharge port 9. A discharge port 12 is provided at the bottom of the metering cylinder 4. The size of the discharge port 12 is adapted to the size between any two of the multiple partition plates 11. An alignment plate 5 is fixedly connected to one side of the bottom of the metering cylinder 4. When the model box 14 is placed on top of the conveyor belt 2, its position is located at the bottom of the output end of the alignment plate 5. The position of the discharge port 12 corresponds to the position of the alignment plate 5. In the initial state, the position between two of the partition plates 11 corresponds to the position of the discharge port 12. Through the metering component, a metering cylinder 4 is set at the bottom of the discharge cylinder 3, and a connecting shaft 10 is provided inside it. Multiple annular equidistant fixed partition plates 11 form several quantitative cavities, enabling single quantitative output of materials. Due to the limitation of the spacing between the partition plates 11 and the control of the motor, excessive material accumulation can be avoided, the amount of material supplied per unit time can be controlled, and the consistency of raw materials before each alkali-resistant brick is significantly improved. When the material is input into the inside of the quantitative cylinder 4 from the discharge port 9 at the bottom of the rotating paddle 8, the position between two partition plates 11 in the initial state corresponds to the position of the discharge port 9. At this time, the material is input between the two partition plates 11. Then, by starting the second motor 7 to drive the connecting shaft 10 to rotate, the partition plates 11 output the material from the inside of the discharge port 12. At this time, by setting the size of the discharge port 12 to be equal to the spacing between the two partition plates 11, the material is input into the inside of the alignment plate 5 at one time, and then input into the inside of the mold box 14 through the alignment plate 5 for molding.
[0033] Two fixed boxes 33 are installed on the outside of the conveyor belt 2. A fixed frame 16 is installed on one side of the fixed box 33. A guide rod 18 is slidably connected to one end of the top of the fixed frame 16. A fixed plate 17 is fixedly connected to the fixed frame 16 on the top side of the conveyor belt 2. The bottom of the guide rod 18 passes through the inside of the fixed plate 17 and is fixedly connected to the top of the compaction plate 21. A fixed ring 20 is fixedly connected to the outside of the top of the fixed plate 17. A first spring 19 is fixedly connected to the top of the fixed ring 20. The inside of the first spring 19 is sleeved on the outside of the top of the guide rod 18. The top of the first spring 19 is fixedly connected to the top of the fixed frame 16. The compaction plate 21 is fixedly connected to one end of the guide rod 18 that passes through the top of the fixed frame 16. Through the set molding components, after the material is loaded into the mold box 14, it is pressed by the compaction plate 21. The initial compaction operation can be achieved. When the material enters the mold box 14, the conveyor belt 2 is activated, causing the pusher plate 24 to move the mold box 14. When one side of the mold box 14 moves to the bottom of the compaction plate 21, it will lift the compaction plate 21 and move the guide rod 18 upward while the first spring 19 contracts. When the top of the mold box 14 coincides with the bottom of the compaction plate 21, the first spring 19 automatically rebounds, causing the guide rod 18 to move the compaction plate 21 downward, causing the compaction plate 21 to compact the material inside the top of the mold box 14. This structural design can significantly improve the pre-compaction density of the brick material, help reduce the porosity during the molding process, thereby improving the mechanical properties and density of the alkali-resistant brick. At the same time, the compaction plate 21 also serves to limit the position of the guide rod 18.
[0034] The bottom of the compaction plate 21 has two arc-shaped openings on both sides. An arc-shaped block 15 is fixedly connected to one side of the model box 14, and a limiting block 31 is fixedly connected to one side of the arc-shaped block 15. A guide plate 22 is fixedly connected to the top of one end of the fixed box 33. A limiting groove 32 is opened on the top of the guide plate 22. The end of the limiting block 31 away from the arc-shaped block 15 is slidably connected to the inside of the limiting groove 32. When the limiting block 31 slides inside the limiting groove 32, the position of the model box 14 corresponds to the position of the compaction plate 21. The guide plate 22... The length of the compaction plate 21 is greater than the distance from the initial end of the conveyor belt 2. The compaction plate 21 has rounded sides at the bottom, which facilitates the lifting of the model box 14. At the same time, with the setting of the limiting block 31 and the limiting groove 32, when placing the model box 14, the limiting block 31 is first aligned with the position of the limiting groove 32. This makes the position of the model box 14 correspond to the position of the compaction plate 21, thereby avoiding the problem of the model box 14 shifting before the compaction plate 21 compacts the model box 14.
[0035] The spacing between two adjacent push plates 24 is greater than the width of the model box 14. Multiple connecting cylinders 25 are fixedly connected to one side of the push plate 24 in the model box 14. A second spring 26 is installed inside the connecting cylinder 25. A shrinking rod 27 is slidably engaged inside one end of the connecting cylinder 25. One end of the second spring 26 is fixedly connected to one end of the shrinking rod 27. Through the cooperation of the multiple push plates 24 with the model box 14, the brick material is pushed forward during the transmission process. When the model box 14 moves past the bottom of the compaction plate 21, the elastic retraction between the connecting cylinder 25 and the shrinking rod 27 allows the push plate 24 to flexibly adapt to the back and forth movement of the model box 14, further promoting the uniform distribution of material in the model box 14 and avoiding local empty corners, layering, or uneven density caused by static material distribution.
[0036] A baffle plate 30 is fixedly connected to the top of the fixed box 33 at the end away from the guide plate 22. Multiple grooves 23 are evenly spaced on one side of the baffle plate 30. The dimensions of the grooves 23 are larger than those of the arc-shaped block 15. The baffle plate 30 is located behind the compaction plate 21. The top of the baffle plate 30 is lower than the bottom of the limiting groove 32, and one end of the limiting groove 32 passes through one end of the guide plate 22. A positioning post 28 is fixedly connected to one side of the fixed box 33 corresponding to the groove 23. A buffer cylinder 29 is slidably engaged with the end of the positioning post 28 away from the fixed box 33. A third spring is installed inside the buffer cylinder 29. The end of the positioning post 28 connected to the buffer cylinder 29 is fixedly connected to one end of the third spring. An inclined arc plate 13 is fixedly connected to the end of the cylinder 29 away from the positioning post 28. The position of the inclined end of the arc plate 13 corresponds to the position of the groove 23. When the model box 14 moves between the inclined end of the arc plate 13 and the groove 23, the third spring is in a rebound state. When the model box 14 moves to the side of the buffer cylinder 29 and the baffle plate 30, the third spring is in a compression state. By setting that when the material inside the model box 14 is compacted and continues to move to the position between the buffer cylinder 29 and the baffle plate 30, because there are multiple grooves 23 on one side of the baffle plate 30 and an arc block 15 on one side of the model box 14, the model box 14 will sway slightly from side to side as it slides through the groove 23 area. This structure cleverly utilizes the cooperation between the groove 23 and the arc block 15 to allow the model box 14 to shake without the need for an additional power structure. This promotes a slight self-flow and rearrangement of the material within the mold cavity, making the brick structure more uniform and compact, and significantly reducing porosity. When the model box 14 moves to one side of the arc plate 13, it will first be guided by the arc plate 13 to move between the buffer cylinder 29 and the baffle plate 30. At this time, because the inclined end of the baffle plate 30 corresponds to the position of the groove 23, the model box 14 will not be blocked by the arc plate 13 due to the influence of the arc block 15, thus preventing it from moving. When the model box 14 moves to... When the buffer cylinder 29 is between the baffle plate 30, the pressure of the arc block 15 on one side of the baffle plate 30 causes the mold box 14 to shift to one side of the buffer cylinder 29, causing the positioning post 28 and the third spring to contract. Then, when the arc block 15 moves past one side of the baffle plate 30 and moves to one side of the groove 23, the third spring automatically rebounds, causing the mold box 14 to shift to one side of the baffle plate 30. This left-right movement achieves the effect of making the material shake evenly. It should also be noted that the number of positioning posts 28 can be set to multiple, so that when the mold box 14 moves to the side of the buffer cylinder 29 and the baffle plate 30, it can create multiple left-right shaking effects, thereby making the material more compact.
[0037] Work steps
[0038] In this embodiment, the following steps are taken: First, the mixed raw materials of multiple alkali-resistant bricks are placed inside the feeding cylinder 1. Then, the first motor 6 is started to control the rotation of the rotating paddle 8, causing the rotating paddle 8 to evenly output the material inside the feeding cylinder 1. When the material is input into the metering cylinder 4 from the discharge port 9 at the bottom of the rotating paddle 8, the material is input between the two partition plates 11, as the initial position of two partition plates 11 corresponds to the position of the discharge port 9. Then, the second motor 7 is started to drive the connecting shaft 10 to rotate, causing the partition plates 11 to output the material from the discharge port 12. At this time, the specifications and dimensions of the discharge port 12 are set to match the material's internal dimensions. The equal spacing between the two partition plates 11 allows material to be fed into the alignment plate 5 in one go, and then into the mold box 14 for molding. When the material enters the mold box 14, the conveyor belt 2 is activated, causing the pusher plate 24 to move the mold box 14. When one side of the mold box 14 moves to the bottom of the compaction plate 21, it will lift the compaction plate 21 and move the guide rod 18 upwards while the first spring 19 contracts. When the top of the mold box 14 coincides with the bottom of the compaction plate 21, the first spring 19 automatically rebounds, causing the guide rod 18 to move the compaction plate 21 downwards, causing the compaction plate 21 to press the material inside the top of the mold box 14. During compaction, as the model box 14 moves past the bottom of the compaction plate 21, the retraction rod 27, carrying the second spring 26, retracts when the model box 14 contacts one side of the bottom of the compaction plate 21. When the model box 14 is completely moved to the bottom of the compaction plate 21, the second spring 26, carrying the retraction rod 27, automatically rebounds. Through the elastic rebound action between the connecting cylinder 25 and the retraction rod 27, the push plate 24 can flexibly adapt to the back-and-forth movement of the model box 14, further promoting the uniform distribution of material within the model box 14. Then, when the model box 14 moves to one side of the arc plate 13, it will first move between the buffer cylinder 29 and the baffle plate 30 guided by the arc plate 13. At this time, due to the setting of the baffle plate 29, the material is further distributed evenly within the model box 14. The inclined end of the baffle 30 corresponds to the position of the groove 23. During the guiding process, the model box 14 will not be blocked by the arc plate 13 due to the influence of the arc block 15, thus preventing it from moving. When the model box 14 moves between the buffer cylinder 29 and the baffle 30, the pressure of the arc block 15 and the baffle 30 causes the model box 14 to shift to one side of the buffer cylinder 29, causing the positioning post 28 and the third spring to retract. Afterward, when the arc block 15 moves past the baffle 30 and moves to the side of the groove 23, the third spring automatically rebounds, causing the model box 14 to shift to one side of the baffle 30. In this way, the material is shaken evenly by moving left and right.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
