Description

Technical Field

[0001] This invention relates to the field of brick structure manufacturing technology, and in particular to a composite permeable brick seat structure and its manufacturing process. Background Technology

[0002] Bricks are small, man-made blocks used in industrial processes. They play a vital role in the manufacturing and development of various industrial products. The base brick, specifically, is a refractory brick placed at the bottom of a steel ladle to fix the nozzle brick. The base brick's functions include fixing the nozzle position; facilitating nozzle removal and installation; supporting the lower end of the stopper rod during pouring; and ensuring the stopper rod slides along the curved surface towards the nozzle after pouring to cut off the flow. With the advancement of industrialization, the use of steel ladles for transporting and pouring molten metal has increased significantly, leading to a corresponding rise in the usage of base bricks, which form the foundation of these ladles. To cope with the various influences of the steel ladle and the external environment, the structure of the base bricks must be updated accordingly, ensuring they remain relevant and not obsolete. The permeability of the brick facilitates its long-term preservation, guaranteeing the reliability of the ladle's quality and allowing for its continued use in the market.

[0003] Chinese Patent Publication No. CN213927034U, published on August 10, 2021, discloses a detachable green non-fired breathable brick structure, including a breathable brick body, limiting posts, breathable holes, and a breathable core. The breathable brick body has connecting holes on both the front and rear sides, with limiting posts penetrating through the connecting holes. Compression strips are penetrating through the top left and right sides of the limiting posts, and the outer walls of the compression strips on both sides of the limiting posts are fixedly connected by a first spring. Locking strips are penetrating through the lower left and right sides of the limiting posts, and the bottom surfaces of the locking strips on both sides of the limiting posts are fixedly connected to the connecting head. The top of the permeable brick body is connected to the bottom of the connector by a second spring. A main sliding block is fixedly installed inside the limiting post. A ventilated hole is opened in the middle of the permeable brick body, and a permeable core is inserted through the ventilated hole. Anti-slip posts are inserted through the left and right sides of the permeable core. Connecting rods are fixedly installed on the outer walls of the anti-slip posts on both sides of the permeable core. A pull rod is inserted through the permeable core, and the bottom end of the pull rod is fixedly connected to the outer wall of the connecting rod. A secondary sliding block is slidably installed at the bottom of the anti-slip posts inside the permeable core, and the bottom of the secondary sliding block is fixedly connected to the bottom outer wall of the permeable core by a third spring. The drawback of this technical solution is that while the limiting post can control the connection between the two permeable brick bodies and prevent slippage between them, it does not provide a corresponding limiting design for the steel drum to be fixed on, thus failing to provide further limiting effect on the steel drum.

[0004] In summary, a structure can be designed to provide additional restraint for the steel drum, reducing the probability of it tipping over during operation. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of existing technologies that do not have a further limiting structure for the placement of steel drums, and provides a composite permeable brick seat structure and its manufacturing process that can automatically open a limiting effect during the placement of steel drums.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A composite permeable brick base structure includes a base body with slots and air vents. The base body has two slots, one at the top and one at the bottom. Each slot includes a slot side one, a slot side two, and a slot bottom. Slot side one is symmetrically distributed at the front and rear ends of the slot bottom, and slot side two is symmetrically distributed at the left and right ends. Slot side two has several insertion holes, and the air vents are also several. Each insertion hole corresponds to an air vent and is connected to it. An insertion tube and an elastic block are installed inside each insertion hole. Several permeable holes are evenly distributed on the insertion tube. One end of the insertion tube passes through the insertion hole and is placed inside the slot, while the other end is connected to the base body via the elastic block.

[0007] This design allows the steel drum to be inserted through slots on the base brick. Each slot includes two slot sides: one, two slot sides, and a slot bottom. Two slot sides are symmetrically distributed at the front and rear ends of the slot bottom, and two slot sides are symmetrically distributed at the left and right ends. When inserting the steel drum, its outer edge is restrained by the slot sides. Several insertion holes are provided on the slot sides. Inserted tubes pass through these holes, one end of which is placed inside the slot, while the other end connects to an elastic block inside the insertion hole. During insertion, the steel drum contacts the end of the insertion tube inside the slot, causing it to move inward under the influence of the pushing force. The elastic block ensures stable inward movement. Furthermore, when the steel drum is stably placed on the slot bottom, the elastic block's action on each insertion tube maintains its stable position, thus achieving the purpose of automatically activating a restraining effect during the placement of the steel drum. The air vents on the brick base correspond one-to-one with the insertion holes on the second side of the slot and are connected, which ensures the breathability of the brick base structure and facilitates the long-term use of the brick base.

[0008] Preferably, the insertion tube is provided with a connecting groove, in which a rolling bearing is installed. A rolling shaft is mounted on the rolling bearing, and both ends of the rolling shaft are connected to the insertion tube. This design allows the rolling shaft to be connected via the connecting groove on the insertion tube, and the rolling shaft can be reliably connected to the rolling bearing. This ensures that the rolling bearing is stably confined within the connecting groove. When the steel drum is placed, it will contact the rolling shaft, which not only facilitates the lowering process but also reduces the friction between the steel drum and the base brick, making it safe and reliable.

[0009] Preferably, a roller is installed at the vent hole, the diameter of which is larger than the diameter of the roller. A rolling shaft is mounted on the roller, and the rolling shaft is detachably connected to the insertion tube. This design not only ensures the air permeability of the insertion tube through the vent hole, but also allows the roller inside the vent hole to be connected to the insertion tube via the rolling shaft. Thus, when the steel drum is placed, the insertion tube moves under the pushing force of the steel drum, which is due to the rolling effect of the roller, reducing the friction between the insertion tube and the base brick and lowering the probability of damage to the insertion tube due to friction.

[0010] Preferably, the rolling bearing includes an inner ring and an outer ring, the rolling shaft is connected to the inner ring, and protective sleeves are fitted on both the outer ring and the roller. This design allows for a secure connection between the inner ring and the rolling shaft, which in turn connects the rolling bearing to the insertion tube. The protective sleeves on the outer ring and roller protect them from damage during operation, preventing the placement of the steel drum and its support bricks.

[0011] Preferably, the front end of the seat brick is provided with an insertion groove, and the rear end of the seat brick is installed with an insertion block, the insertion block matching the insertion groove. This design, with the insertion groove at the front end and the insertion block at the rear end, allows the two seat bricks to be stably connected through the matching insertion groove and the insertion block. This prevents the two seat bricks from shifting during the placement of the steel drum, thus preventing the steel drum from collapsing.

[0012] Preferably, the plug-in block has plug-in holes, and a plug-in rod is installed in the plug-in holes. The plug-in groove has two connecting holes, which are respectively located at the upper and lower ends of the plug-in groove. The two ends of the plug-in rod are plugged into the two connecting holes respectively. This design allows the plug-in rod to be smoothly inserted through the plug-in holes on the plug-in block. Furthermore, the plug-in groove also has two connecting holes, which are respectively located at the upper and lower ends of the plug-in groove. This allows the two ends of the plug-in rod inserted in the plug-in hole to be inserted into the two connecting holes respectively. This completes the connection between the plug-in groove and the plug-in block, which is also the connection between the two base bricks. It is simple and easy.

[0013] Preferably, the connector rod is equipped with a first turntable and a second turntable, which are respectively positioned at the upper and lower ends of the connector rod. The diameters of both turntables are larger than the diameter of the connector rod. Each turntable corresponds to a connecting hole, and both turntables are detachably connected to the base brick. This design allows turntables to be connected to the upper and lower ends of the connector rod. Since the diameters of both turntables are larger than the diameter of the connector rod, this design prevents the connector rod from detaching from the connector block through the connector hole, ensuring a stable connection between the connector slot and the connector block, and guaranteeing a stable connection between the two base bricks.

[0014] Preferably, the turntable is provided with screw holes, and the connector rod has several air holes evenly distributed on it, with the screw holes communicating with the air holes. This design allows for easy connection between the turntable and the connector rod using a screwdriver via the screw holes, and the evenly distributed air holes on the connector rod ensure proper ventilation by maintaining the connection between the screw holes and the air holes.

[0015] Preferably, the screw hole has a connecting hole, the diameter of which is larger than the diameter of the connecting hole. Several vents are symmetrically distributed on the connecting hole, and these vents communicate with the screw hole through the connecting hole. This design allows for proper communication between the screw hole and the vents. The symmetrical distribution of the vents on the connecting hole ensures that air can easily escape from the vents to the screw hole, providing comprehensive ventilation. Furthermore, the larger diameter of the screw hole reduces the probability of the screwdriver entering the connecting hole when inserted.

[0016] This invention also provides a manufacturing process for composite permeable brick bases, specifically including the following steps: Step 1: Make a connecting hole and several air holes on the plug rod. The air holes are symmetrically distributed around the connecting hole, and the air holes are connected to the connecting hole. Step 2: Make turntable 1 and turntable 2 at the top and bottom ends of the connector rod respectively. The diameter of turntable 1 and the diameter of turntable 2 are both larger than the diameter of the connector rod. Make screw holes on turntable 1. The diameter of the screw holes is larger than the diameter of the connecting hole. The air hole is connected to the screw hole through the connecting hole. Step 3: A slot is made at the front end of the brick body, and two connecting holes are made at the upper and lower ends of the slot. Turntable 1 and Turntable 2 correspond to the two connecting holes one by one. The plug block is installed at the rear end, and a plug hole is made on the plug block to facilitate the insertion of the plug rod. Step 4: Slots and several air vents are made at the top and bottom of the brick body. Insertion holes are made inside the two sides of the slots so that the insertion holes correspond one-to-one with the air vents. The insertion holes need to be connected to the air vents. An elastic block is installed in the insertion hole. The end of the insertion tube installed on the elastic block passes through the insertion hole and is placed in the slot.

[0017] The beneficial effects of this invention are: it can achieve the purpose of automatically opening a limit switch during the placement of the steel drum; it facilitates a stable connection between the two seat bricks; and it has a stable and breathable effect for the brick seat.

[0020] The invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4In the illustrated embodiment, a composite permeable brick seat structure includes a seat body 1. The seat body 1 is provided with slots and air vents 9. There are two slots, which are respectively located at the top and bottom of the seat body 1. Each slot includes a slot side 4, a slot side 5, and a slot bottom 6. Both slot side 4 and slot side 5 are provided with two slots. The two slot side 4 are symmetrically distributed at the front and rear ends of the slot bottom 6, and the two slot side 5 are symmetrically distributed at the left and right ends of the slot bottom 6. The slot side 5 is provided with a number of insertion holes 16. There are a number of air vents 9. The insertion holes 16 correspond one-to-one with the air vents 9 and are connected to the air vents 9. An insertion tube 18 and an elastic block 17 are installed in the insertion hole 16. A number of permeable holes 21 are evenly distributed on the insertion tube 18. One end of the insertion tube 18 passes through the insertion hole 16 and is placed in the slot. The other end of the insertion tube 18 is connected to the seat body 1 through the elastic block 17.

[0022] like Figure 4 and Figure 5 As shown, the insertion tube 18 is provided with a connecting groove 19, and a rolling bearing 10 is installed in the connecting groove 19. A rolling shaft is installed on the rolling bearing 10, and both ends of the rolling shaft are connected to the insertion tube 18. A roller 20 is installed at the vent hole 21. The diameter of the vent hole is larger than the diameter of the roller 20. A rolling shaft 22 is installed on the roller 20, and the rolling shaft 22 is detachably connected to the insertion tube 18. The rolling bearing 10 includes an inner ring and an outer ring. The rolling shaft is connected to the inner ring, and protective sleeves 23 are fitted on both the outer ring and the roller 20.

[0023] like Figure 1 , Figure 2 and Figure 6 As shown, the front end of the brick base 1 is provided with a insertion groove 2, and the rear end of the brick base 1 is equipped with an insertion block 3, which matches the insertion groove 2. The insertion block 3 is provided with an insertion hole 8, and an insertion rod 11 is installed at the insertion hole 8. The insertion groove 2 is provided with two connection holes 7, which are respectively located at the upper and lower ends of the insertion groove 2. The two ends of the insertion rod 11 are respectively inserted into the two connection holes 7. A turntable 12 and a turntable 25 are installed on the insertion rod 11, which are respectively located at the upper and lower ends of the insertion rod 11. The diameters of the turntable 12 and the turntable 2 are both larger than the diameter of the insertion rod 11. The turntable 12 and the turntable 2 correspond one-to-one with the connection holes 7, and both the turntable 12 and the turntable 2 are detachably connected to the brick base 1. The turntable 12 has screw holes 13, and the plug rod 11 has several air holes 24 evenly distributed on it. The screw holes 13 are connected to the air holes 24. The screw holes 13 have connecting holes 14, and the diameter of the screw holes 13 is larger than the diameter of the connecting holes 14. Several air holes 24 are symmetrically distributed on the connecting holes 14, and the air holes 24 are connected to the screw holes 13 through the connecting holes 14.

[0024] This invention also provides a manufacturing process for composite permeable brick bases, specifically including the following steps: Step 1: Make a connecting hole 14 and several air holes 24 on the plug rod 11. The air holes 24 are symmetrically distributed around the connecting hole 14, and the air holes 24 are connected to the connecting hole 14. Specifically, a connecting hole 14 and several air holes 24 are first made on the plug rod 11. The upper and lower ends of the connecting hole 14 can pass through the upper and lower ends of the plug rod 11 respectively, and the several air holes 24 are symmetrically distributed with the connecting hole 14 as the center, thus completing the connection between the air holes 24 and the connecting hole 14.

[0025] Step 2: Make turntable 12 and turntable 25 at the upper and lower ends of the plug rod 11 respectively. The diameter of turntable 12 and the diameter of turntable 2 15 are both larger than the diameter of plug rod 11. Make screw hole 13 on turntable 12. The diameter of screw hole 13 is larger than the diameter of connecting hole 14. Air hole 24 is connected to screw hole 13 through connecting hole 14. Specifically, based on the structure of the upper and lower ends of the connector 11, turntable 12 and turntable 2 15 can be fabricated respectively. The diameters of both turntable 12 and turntable 2 15 need to be larger than the diameter of the connector 11. Threads can be made at both ends of the connector 11, and corresponding threads can be made on turntables 12 and 2 15 to facilitate connection between them and the upper and lower ends of the connector 11. Then, screw holes 13 are made on turntable 12, allowing them to connect with the connecting hole 14. This allows gas from the vent 24 on the connector 11 to pass smoothly through the connecting hole 14 and then exit through the screw hole 13. The diameter of the screw hole 13 must be larger than the diameter of the connecting hole 14 to prevent the screwdriver from being inserted into the connecting hole 14 when controlling turntable 12, thus preventing the control of turntable 12 from being interrupted.

[0026] Step 3: A slot 2 is made at the front end of the brick body 1. Two connecting holes 7 are made at the upper and lower ends of the slot 2. Turntable 12 and turntable 25 correspond one-to-one with the two connecting holes 7. The plug block 3 is installed at the rear end. The plug block 3 has a plug hole 8 to facilitate the insertion of the plug rod 11. Specifically, a slot 2 is made at the front end of the base brick 1. Two connecting holes 7 are made at the upper and lower ends of the slot 2. Turntable 12 and Turntable 25 are respectively matched with the two connecting holes 7 so that they can be smoothly connected to the front end of the base brick 1. Then, a connector block 3 is installed at the mounting point of the base brick 1. The connector hole 8 on this connector block 3 allows the connector rod 11 to be smoothly inserted into it. This allows the insertion block 3 on one brick body 1 to be inserted into the insertion slot 2 on another brick body 1. Then, the insertion rod 11 is inserted into the connection hole 7 at the upper end of the insertion slot 2, with one end of the insertion rod 11 passing through the insertion hole 8 on the insertion block 3 and being placed in the connection hole 7 at the lower end of the insertion slot 2. Subsequently, the turntable 12 can be placed into the end of the insertion rod 11 in the connection hole 7 at the upper end of the insertion slot 2. A screwdriver is used to connect the insertion rod 11 and the turntable 12. At the same time, the turntable 2 15 can be placed into the end of the insertion rod 11 in the connection hole 7 at the lower end of the insertion slot 2, and the insertion rod 11 and the turntable 2 15 can be connected. This not only connects the insertion slot 2 and the insertion block 3, but also connects the two brick bodies 1.

[0027] Step 4: Slots and several air vents 9 are made at the top and bottom of the brick body 1. Insertion holes 16 are made in the slot side 5 of the slot, so that the insertion holes 16 correspond one-to-one with the air vents 9. The insertion holes 16 need to be connected to the air vents 9. An elastic block 17 is installed in the insertion hole 16. The end of the insertion tube 18 installed on the elastic block 17 passes through the insertion hole 16 and is placed in the slot.

[0028] Specifically, slots and several air vents 9 need to be made at the top and bottom of the brick body 1. The slots include slot side 1 4, slot side 2 5, and slot bottom 6. Slot side 1 4 and slot side 2 5 each contain two slots. The two slot side 1 4 are symmetrically distributed at the front and rear ends of the slot bottom 6, while the two slot side 2 5 are symmetrically distributed at the left and right ends of the slot bottom 6. In addition, several insertion holes 16 are provided on slot side 2 5. The insertion holes 16 correspond one-to-one with the air vents 9 on the brick body 1, thus completing the connection between the insertion holes 16 and the air vents 9. An insertion tube 18 and an elastic block 17 are installed inside the insertion hole 16. One end of the insertion tube 18 is connected to the base brick 1 through the elastic block 17, while the other end of the insertion tube 18 passes through the insertion hole 16 and is placed in the slot. A connecting groove 19 is provided at the end of the insertion tube 18 in the slot. The rolling bearing 10 in the connecting groove 19 includes an inner ring and an outer ring. The rolling shaft installed at the inner ring is connected to the insertion tube 18. Several vent holes 21 are evenly distributed on the insertion tube 18. Rollers 20 are installed at the vent holes 12. Not only is the diameter of the vent holes 21 larger than the diameter of the rollers 20, but the rollers 20 are also connected to the insertion tube 18 through the rolling shafts 22. Here, the rolling bearing can be installed on the insertion tube 18, so that the rolling shafts 22 can be connected to the insertion tube 18 through the rolling bearings. In this way, the rollers 20 can roll smoothly under the support of the insertion tube 18 without affecting each other. When the steel drum is inserted into the slot, it can move smoothly downwards under the limiting effect of the slot side 4 and slot side 5. The steel drum can first touch the outer ring of the rolling bearing 10 in the slot, and smoothly land on the bottom 6 of the slot under the rolling effect of the outer ring. At the same time, the outer ring can push the insertion tube 18 into the insertion hole 16 under the pushing effect of the steel drum. During the movement, it is carried out under the rolling effect of the roller 20. This can reduce the friction between the outer ring and the steel drum, as well as the friction between the roller 20 and the insertion tube 18, thereby reducing the probability of damage to the rolling bearing 10 and the insertion tube 18 during operation.

[0029] First, a connecting hole 14 and several air holes 24 are made on the connector rod 11. The upper and lower ends of the connecting hole 14 can pass through the upper and lower ends of the connector rod 11 respectively, and the air holes 24 are symmetrically distributed with the connecting hole 14 as the center, thus completing the connection between the air holes 24 and the connecting hole 14. Based on the structure of the upper and lower ends of the connector rod 11, turntable one 12 and turntable two 15 can be made respectively. Here, the diameter of turntable one 12 and the diameter of turntable two 15 need to be larger than the diameter of the connector rod 11. Threads can be made on the upper and lower ends of the connector rod 11, and corresponding threads can also be made on turntable one 12 and turntable two 15, thus facilitating the connection between turntable one 12 and turntable two 15 and the upper and lower ends of the connector rod 11. Then, a screw hole 13 is made on the turntable 12 so that it can connect with the connecting hole 14. This allows the gas at the air hole 24 on the connector 11 to pass smoothly through the connecting hole 14 and then be discharged from the screw hole 13. The diameter of the screw hole 13 must be larger than the diameter of the connecting hole 14 to prevent the screwdriver from being inserted into the connecting hole 14 when controlling the turntable 12, thus preventing the turntable 12 from being controlled.

[0030] A slot 2 is made at the front end of the brick base 1. Two connecting holes 7 are made at the upper and lower ends of the slot 2. Turntable 12 and turntable 25 are respectively matched with the two connecting holes 7 so that turntable 12 and turntable 2 can be smoothly connected to the front end of the brick base 1. Then, a plug block 3 is also installed at the installation point of the brick base 1. The plug hole 8 on the plug block 3 allows the plug rod 11 to be smoothly inserted into it. This allows the insertion block 3 on one brick body 1 to be inserted into the insertion slot 2 on another brick body 1. Then, the insertion rod 11 is inserted into the connection hole 7 at the upper end of the insertion slot 2, with one end of the insertion rod 11 passing through the insertion hole 8 on the insertion block 3 and being placed in the connection hole 7 at the lower end of the insertion slot 2. Subsequently, the turntable 12 can be placed into the end of the insertion rod 11 in the connection hole 7 at the upper end of the insertion slot 2. A screwdriver is used to connect the insertion rod 11 and the turntable 12. At the same time, the turntable 2 15 can be placed into the end of the insertion rod 11 in the connection hole 7 at the lower end of the insertion slot 2, and the insertion rod 11 and the turntable 2 15 can be connected. This not only connects the insertion slot 2 and the insertion block 3, but also connects the two brick bodies 1.

[0031] Finally, slots and several air vents 9 need to be made at the top and bottom of the base brick 1. The slots include slot side 1 4, slot side 2 5, and slot bottom 6. Slot side 1 4 and slot side 2 5 each contain two slots. The two slot side 1 4 are symmetrically distributed at the front and rear ends of the slot bottom 6, while the two slot side 2 5 are symmetrically distributed at the left and right ends of the slot bottom 6. In addition, several insertion holes 16 are provided on slot side 2 5. The insertion holes 16 correspond one-to-one with the air vents 9 on the base brick 1, thus completing the connection between the insertion holes 16 and the air vents 9. An insertion tube 18 and an elastic block 17 are installed inside the insertion hole 16. One end of the insertion tube 18 is connected to the base brick 1 through the elastic block 17, while the other end of the insertion tube 18 passes through the insertion hole 16 and is placed in the slot. A connecting groove 19 is provided at the end of the insertion tube 18 in the slot. The rolling bearing 10 in the connecting groove 19 includes an inner ring and an outer ring. The rolling shaft installed at the inner ring is connected to the insertion tube 18. Several vent holes 21 are evenly distributed on the insertion tube 18. Rollers 20 are installed at the vent holes 12. Not only is the diameter of the vent holes 21 larger than the diameter of the rollers 20, but the rollers 20 are also connected to the insertion tube 18 through the rolling shafts 22. Here, the rolling bearing can be installed on the insertion tube 18, so that the rolling shafts 22 can be connected to the insertion tube 18 through the rolling bearings. In this way, the rollers 20 can roll smoothly under the support of the insertion tube 18 without affecting each other. When the steel drum is inserted into the slot, it can move smoothly downwards under the limiting effect of the slot side 4 and slot side 5. The steel drum can first touch the outer ring of the rolling bearing 10 in the slot, and smoothly land on the bottom 6 of the slot under the rolling effect of the outer ring. At the same time, the outer ring can push the insertion tube 18 into the insertion hole 16 under the pushing effect of the steel drum. During the movement, it is carried out under the rolling effect of the roller 20. This can reduce the friction between the outer ring and the steel drum, as well as the friction between the roller 20 and the insertion tube 18, thereby reducing the probability of damage to the rolling bearing 10 and the insertion tube 18 during operation.

[0032] Both the elastic block 17 and the protective sleeve 23 can be made of rubber, which not only has good elasticity but is also sturdy and durable.
