Abstract

This invention relates to a hydraulic drying equipment for refractory materials, comprising a hot air drying system, a drying chamber, and a hot air distribution plate with nozzles. A movable plate, acting on reciprocating and rotating components, moves a mounting frame. The drying chamber's end plate has a movable groove, and sealing gates are located on both sides of the end plate. The thickness of the end plate is greater than the diameter of the nozzle. During advancement, the outer sealing gate opens while the inner sealing gate remains sealed, pushing the mounting frame inward so that the nozzle enters the chamber through the trapezoidal groove. The inner and outer sealing gates then sequentially close, completing a leak-free feeding process for a set of nozzles. During drying, a second telescopic component drives the hot air distribution plate to rise and fall, causing the movable plate to move up and down.

Description

Technical Field

[0001] This invention relates to the field of hot air drying system technology, specifically to a hydraulic drying equipment for refractory materials. Background Technology

[0002] In the production of hydraulically manufactured refractory materials (such as sprue nozzles), drying is a crucial process determining the final product performance. Currently, common drying equipment often employs batch drying chambers, loading the nozzles to be processed in batches and heating them through a hot air circulation system. However, this type of equipment has significant shortcomings in practical use: firstly, loading and unloading nozzles usually requires opening the drying chamber door, leading to a large amount of hot air leakage, wasting heat energy and causing significant temperature fluctuations within the chamber, affecting the stability of the drying effect; secondly, to ensure continuous production, some equipment attempts to use a push-pull feeding method, but the nozzles are fixed on the mounting frame inside the chamber, remaining stationary during drying. Hot air cannot evenly cover the inner and outer surfaces of all nozzles, especially in the central channels, often resulting in drying dead zones and uneven distribution of residual moisture in the product, leading to poor quality consistency. Furthermore, existing equipment lacks an effective dynamic sealing structure during batch loading and unloading, failing to maintain the heat state inside the chamber while gradually replacing the nozzles, thus hindering the balance between production efficiency and energy consumption control.

[0003] Therefore, a hydraulic drying equipment for refractory materials is proposed to address the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a hydraulic drying equipment for refractory materials.

[0005] The objective of this invention is achieved through the following technical solution: a hydraulic drying equipment for refractory materials, comprising: a hot air drying system with a hot air and exhaust system and a drying chamber, wherein a hot air distribution plate connected to the hot air drying system is movably disposed inside the drying chamber, a nozzle is fixedly connected to the hot air distribution plate, a movable plate is horizontally movably disposed on the hot air distribution plate, and the two ends of the movable plate are respectively engaged with a reciprocating component and a rotating component, and both the reciprocating component and the rotating component are movable to the mounting frame; Multiple mounting brackets are installed on each other. The mounting brackets are fixedly connected with plug rods that are inserted into the water inlet and L-shaped levers. The end plate of the drying chamber has a movable groove for the mounting brackets and water inlet to move. The two sides of the end plate are fitted with sealing gates that are inserted into the mounting brackets and press against the bottom plate of the drying chamber. The thickness of the end plate is greater than the diameter of the water inlet.

[0006] As a further description of the above technical solution: The mounting frame is composed of multiple horizontal and vertical bars connected together, with the insertion rod fixedly connected at the connection point of the horizontal and vertical bars. It has a simple structure, strong load-bearing capacity, and uniform distribution of water inlets, which facilitates the circulation of hot air. At the same time, it provides an accurate positioning reference for the subsequent cooperation of the movable groove and sealing gate.

[0007] One end of the crossbar has a mounting hole, and the other end is fixedly connected to a mounting rod. The end of the mounting frame is connected and fixed to an L-shaped actuating rod that slides against the inner wall of the side plate of the drying chamber. This enables the rapid connection and advancement of multiple mounting frames, facilitating feeding of materials in groups.

[0008] The movable channel includes a horizontal channel and a trapezoidal channel. The horizontal channel provides movement for the L-shaped lever, the horizontal bar, and the vertical bar. The trapezoidal channel provides movement for the water inlet and the insertion rod, ensuring that the horizontal bar, the vertical bar, and the water inlet do not interfere with each other.

[0009] Two first telescopic components are fixedly connected to the end plate. Two sealing gates are movably fitted to the inner and outer sides of the end plate. The sealing gates are provided with sealing slots that cooperate with the longitudinal rods. The first telescopic components are connected and fixed to the sealing gates through connecting rods. The inner and outer sealing gates move alternately to realize the leakage-free material replacement logic. The insertion of the sealing slots and the longitudinal rods ensures sealing and allows the longitudinal rods to move within a small range in the slots when the mounting frame is slightly moved.

[0010] A telescopic sleeve is fixedly connected between the hot air distribution plate and the drying chamber. A second telescopic component is fixedly connected to the drying chamber. The telescopic end of the second telescopic component enters the drying chamber and is connected to the hot air distribution plate. Fixed plates that slide against the inner wall of the drying chamber are fixedly connected to both ends of the hot air distribution plate. The movable plate passes horizontally through the fixed plates.

[0011] The reciprocating component includes a reciprocating rod that presses against the end of the movable plate and is rotatably connected to the outside of the drying chamber. The bottom end of the reciprocating rod presses against an L-shaped actuating rod. A rotating groove is provided on the drying chamber, and semi-circular plates are fixedly connected to both sides of the rotating groove. The reciprocating rod passes between the two semi-circular plates, and a circular ring that movably engages with the edges of the two semi-circular plates is fixedly connected to the reciprocating rod. Inclined compression springs are hung between the end of the reciprocating rod and the drying chamber, driving the mounting frame to produce reciprocating micro-movements. The sealing structure is simple and effective, ensuring the reliability of the dynamic seal.

[0012] The rotating component includes a one-way ratchet that engages with the end of the movable plate. The end of the movable plate has a ratchet structure. The one-way ratchet is hollow in the middle. Multiple evenly distributed pressure plates are fixedly connected to the one-way ratchet. The pressure plates engage with an L-shaped lever. A rotating shaft that is rotatably connected to the middle of the multiple pressure plates is fixedly connected to the drying chamber to prevent the cumulative displacement of the sprue position caused by displacement in one direction.

[0013] The bottom plate of the drying chamber is provided with a clearance groove for the rotation of the pressure plate and the reciprocating rod to ensure the running trajectory.

[0014] The unidirectional ratchet and the reciprocating rod are fixedly connected to a fan plate for hot air inside the movable drying chamber. The existing moving parts are used to forcibly disturb the internal hot air, break up the thermal stratification, and improve the uniformity of the temperature field.

[0015] Compared with the prior art, the advantages of the present invention are as follows: This application uses a mounting bracket to connect multiple sets of sprue nozzles. The exposed portion connects to the new mounting bracket to be loaded into the chamber via mounting rods and mounting holes. Simultaneously, the outer sealing gate opens while the inner sealing gate remains sealed. Pushing the mounting bracket inward allows the sprue nozzles to enter the chamber through trapezoidal grooves. The inner and outer sealing gates then sequentially close, completing the leak-free loading of one set of sprue nozzles. During drying, the second telescopic component drives the hot air distribution plate to rise and fall, causing the movable plate to move up and down. One end of the movable plate, through a ratchet structure, drives a one-way ratchet wheel to rotate from its original position, causing the pressure plate to actuate the L-shaped lever. The other end pushes the reciprocating rod to swing. Both actions together cause the mounting bracket to move slightly back and forth horizontally, adjusting the sprue nozzle position to align with the hot air outlet of the nozzle. This continuous micro-movement of the sprue nozzles during drying ensures that the hot air acts evenly on the inner and outer surfaces of the nozzles, improving drying consistency. This structure, while ensuring sealing and reducing heat loss, improves drying quality and achieves a synergy between energy saving and high-efficiency production. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments: like Figures 1-12 The diagram shows an embodiment of a hydraulic drying equipment for refractory materials provided by the present invention, comprising: a hot air drying system 1 with a hot air and exhaust system and a drying chamber 2. A hot air distribution plate 3 connected to the hot air drying system 1 is movably disposed inside the drying chamber 2. A nozzle 4 is fixedly connected to the hot air distribution plate 3. A movable plate 5 is horizontally movably disposed on the hot air distribution plate 3. The two ends of the movable plate 5 are respectively engaged with a reciprocating component and a rotating component. Both the reciprocating component and the rotating component allow for the movement of the mounting frame. A sealing gate 9 slides on the inner and outer sides of the end plate 8, and cooperates with the movable groove to achieve sealing when the water inlets enter and exit the chamber in groups. The thickness design of the end plate 8 ensures that the water inlets are always blocked by the sealing gate 9 when entering and exiting, preventing hot air from directly reaching the outside. The reciprocating component includes a reciprocating rod 21 that presses against the end of the movable plate 5 and is rotatably connected to the outside of the drying chamber 2. The bottom end of the reciprocating rod 21 presses against the L-shaped actuating rod 7. The drying chamber 2 has a rotating groove 22, and semi-circular plates 23 are fixedly connected to both sides of the rotating groove 22. The reciprocating rod 21 passes between the two semi-circular plates 23. A circular ring 24 that movably engages with the edges of the two semi-circular plates 23 is fixedly connected to the reciprocating rod 21. A compression spring 25, which is inclinedly distributed, is hung between the end of the reciprocating rod 21 and the drying chamber 2. When the movable plate 5 rises and falls, it pushes the reciprocating rod 21 to swing around the rotating shaft. The bottom end of the reciprocating rod 21 actuates the L-shaped actuating rod 7 to move the mounting bracket horizontally. The circular ring 24 and the semi-circular plates 23 form a rotary sealing structure to prevent hot air from leaking from the rotating groove 22. The compression spring 25 provides a restoring force to keep the reciprocating rod 21 in close contact with the end of the movable plate 5, eliminating gaps.

[0019] The rotating component includes a one-way ratchet 26 that engages with the end of the movable plate 5. The end of the movable plate 5 has a ratchet structure. The one-way ratchet 26 is hollow in the middle. Multiple evenly distributed pressure plates 27 are fixedly connected to the one-way ratchet 26. The pressure plates 27 engage with the L-shaped lever 7. The middle of the multiple pressure plates 27 is fixedly connected to a rotating shaft 28 that is rotatably connected to the drying chamber 2. When the movable plate 5 descends, the ratchet slides along the tooth surface of the one-way ratchet 26 (the one-way ratchet 26 does not rotate). When the movable plate 5 rises, the ratchet pushes the one-way ratchet 26 to rotate in one direction. The one-way ratchet 26 drives the pressure plates 27 to rotate. The pressure plates 27 move the L-shaped lever 7 to move the mounting frame horizontally in the other direction.

[0020] In this application, multiple mounting brackets are installed on each other. The mounting brackets are fixedly connected with a plug rod 6 that is inserted into the water inlet and an L-shaped lever 7. The mounting brackets support the water inlet through the plug rod 6, and the L-shaped lever 7 serves as the force-bearing point. The end plate 8 of the drying chamber 2 has movable grooves for the installation frame and water inlet to move. The movable grooves include a horizontal groove 14 and a trapezoidal groove 15. The horizontal groove 14 allows the L-shaped actuating rod 7, the horizontal bar 10, and the vertical bar 11 to move, while the trapezoidal groove 15 allows the water inlet and the insertion rod 6 to move. Sealing gates 9 are slidably fitted on both sides of the end plate 8, which are inserted into the installation frame and press against the bottom plate of the drying chamber 2. The thickness of the end plate 8 is greater than the diameter of the water inlet. The hot air distribution plate 3 is connected to the hot air system through a telescopic sleeve 18, and hot air is blown towards the water inlet through nozzles 4. The movable plate 5 is driven when the hot air distribution plate 3 is raised or lowered, and its two ends drive a reciprocating component (reciprocating rod 21) and a rotating component (one-way ratchet 26), respectively, which together apply a slight horizontal displacement to the installation frame.

[0021] The mounting frame is composed of multiple horizontal bars 10 and vertical bars 11 connected together. The insertion rod 6 is fixedly connected to the connection between the horizontal bars 10 and the vertical bars 11. The horizontal bars 10 and the vertical bars 11 form a grid-like frame. The insertion rod 6 is located at the intersection node. The sprue is inserted into the insertion rod 6 to form multi-point support, ensuring the stability of the sprue in a vertical or horizontal position.

[0022] Regarding the assembly of the mounting frame: One end of the crossbar 10 has a mounting hole 12, and the other end is fixedly connected to a mounting rod 13. The end of the mounting frame is connected and fixed to an L-shaped actuating rod 7 that slides in cooperation with the inner wall of the side plate of the drying chamber 2. Adjacent mounting frames can quickly connect by inserting the mounting rod 13 into the mounting hole 12 to form a series chain. The L-shaped actuating rod 7 acts as a guide and slides along the inner wall of the side plate of the drying chamber 2, constraining the mounting frame to move only in the in-and-out direction.

[0023] Two first telescopic members 16 are fixedly connected to the end plate 8. Two sealing gates 9 are movably fitted against the inner and outer sides of the end plate 8. The sealing gates 9 have sealing grooves 17 that engage with the longitudinal rods 11. The first telescopic members 16 are connected and fixed to the sealing gates 9 via connecting rods. The first telescopic members 16 (such as cylinders or electric cylinders) drive the inner and outer sealing gates 9 to slide up and down via the connecting rods. When the sealing gates 9 descend, the sealing grooves 17 lock the longitudinal rods 11 to form a seal; when they rise, they release the longitudinal rods 11, allowing the mounting frame to move.

[0024] A telescopic sleeve 18 is fixedly connected between the hot air distribution plate 3 and the drying chamber 2. A second telescopic component 19 is fixedly connected to the drying chamber 2. The telescopic end of the second telescopic component 19 passes into the drying chamber 2 and is connected to the hot air distribution plate 3. Fixed plates 20 that slide and cooperate with the inner wall of the drying chamber 2 are fixedly connected to both ends of the hot air distribution plate 3. The movable plate 5 passes horizontally through the fixed plate 20. The second telescopic component 19 drives the hot air distribution plate 3 to rise and fall. The telescopic sleeve 18 extends and retracts accordingly to ensure a continuous supply of hot air. The fixed plate 20 slides along the inner wall of the chamber. The movable plate 5 passes horizontally through the fixed plate 20 and remains horizontal during rising and falling. At the same time, it can slide horizontally relative to the fixed plate 20, converting the rising and falling motion into a driving force for the reciprocating and rotating components at both ends.

[0025] Furthermore, to ensure the movement of the pressure plate 27 and the reciprocating rod 21, a clearance groove 29 is provided on the bottom plate of the drying chamber 2 to allow the pressure plate 27 and the reciprocating rod 21 to rotate.

[0026] Among them, the one-way ratchet 26 and the reciprocating rod 21 are fixedly connected to the fan plate 30 for hot air in the movable drying box 2. The fan plate 30 moves with the movement of the one-way ratchet 26 and the reciprocating rod 21, stirring the hot air flow in the box.

[0027] Working principle: The drying chamber 2 originally contains an installation rack, with a portion of the rack protruding to the outside. At this time, the sealing gate 9 presses against the crossbar 10 between the two sets of water inlets, maintaining a sealed, leak-free state. When it is necessary to add a new installation rack and water inlets into the drying chamber 2, and to remove the already dried water inlets from the drying chamber 2, the specific operation is as follows: First, install the sprue onto the insert rod 6 on the mounting bracket manually or using a robotic arm; Then, the undried mounting bracket is installed with a portion of the exposed part of the mounting bracket entering the drying chamber 2, that is, the connection and fixation of the two mounting brackets are completed by the insertion of the mounting rod 13 and the mounting hole 12; and the two mounting brackets (the mounting bracket on the outside and the mounting bracket entering the drying chamber 2) are moved along the bottom plate of the drying chamber 2. At the same time, the first telescopic component 16 located on the outer side is activated, causing the sealing gate 9 located on the outer side to open, while the sealing gate 9 located on the inner side remains stationary. After the water inlet moves into the trapezoidal groove 15, the first telescopic member 16 located on the outer side is activated, causing the sealing gate 9 located on the outer side to move downward, re-sealing the outer side of the trapezoidal groove 15, and the first telescopic member 16 located on the inner side is activated, causing the sealing gate 9 located on the inner side to move upward. Continue to move the outer mounting brackets so that the two mounting brackets move inward. After the water inlet in the trapezoidal groove 15 enters the drying chamber 2, activate the first telescopic component 16 located on the inner side so that the sealing gate 9 located on the inner side moves downward and presses against the longitudinal rod 11 to complete the sealing process and prevent excessive leakage of hot air. The process involves gradually introducing a group of water inlets into the drying chamber 2. In this way, the water inlets are introduced into the drying chamber 2 one group at a time for drying. After the set drying time, the multiple groups of water inlets are removed from the drying chamber 2 one by one, ensuring that the drying work is carried out in an orderly manner and guaranteeing the drying quality.

[0028] Another explanation regarding drying inside the drying chamber 2: First, keep the position of the hot air distribution plate 3 unchanged. When multiple sets of water inlets are drying inside the drying chamber 2, the hot air drying system 1 will send hot air into the hot air distribution plate 3 through the telescopic sleeve 18, thereby ensuring the temperature inside the drying chamber 2 and drying the water inlets. Then, during the drying process, by activating the second telescopic component 19, the hot air distribution plate 3 moves downward and close to the water inlet, and the telescopic sleeve 18 expands and contracts accordingly without affecting the supply of hot air. As the hot air distribution plate 3 moves downward, it drives the fixed plate 20 and the movable plate 5 to move downward synchronously. Under the action of the compression spring 25, the two ends of the movable plate 5 are tightly attached to the reciprocating rod 21 and the one-way ratchet 26 respectively. When the movable plate 5 moves downward while maintaining a horizontal state, one end of the movable plate 5 (the end with the ratchet structure) moves along the one-way ratchet 26, and the one-way ratchet 26 does not rotate, so that the movable plate 5 moves in the horizontal direction close to the one-way ratchet 26, thereby causing the reciprocating rod 21 to rotate at a certain angle, so that the bottom end of the reciprocating rod 21 contacts the L-shaped actuating rod 7. On the one hand, the position of the movable mounting bracket is adjusted so that the movement of the water inlet helps with drying. On the other hand, the position of the water inlet is adjusted so that the position of the water inlet is close to the nozzle 4, so that the hot air from the nozzle 4 can be sprayed into the middle of the water inlet. The center of the semi-circular plate 23 and the circular ring 24 coincides with the pivot of the reciprocating rod 21. When the reciprocating rod 21 rotates, the circular ring 24 rotates from its original position, thereby sealing the rotation groove 22 between the two semi-circular plates 23. This ensures both the rotation of the reciprocating rod 21 and the sealing, preventing heat leakage. Finally, the second telescopic component 19 is activated, causing the hot air distribution plate 3 to move upward, which in turn moves the movable plate 5 upward. The reciprocating rod 21 moves away from the mounting frame. At this time, the end of the movable plate 5 (one end of the ratchet) drives the one-way ratchet 26 to rotate in its original position, thereby causing the pressure plate 27 to rotate, which in turn drives the mounting frame and the water inlet to move (moving closer to the reciprocating rod 21), thereby improving the drying quality.

[0029] It is worth noting that in this application, the nozzle 4 will not enter the middle of the sprue; it is only necessary that the middle of the sprue is located within the spray area of ​​the nozzle 4. During the process of adjusting the position of the mounting frame by the reciprocating rod 21 and the pressure plate 27, the longitudinal rod 11 of the mounting frame moves within the sealing groove 17. The moving distance of the mounting frame is less than the distance between the two sets of water inlets, so as to prevent the water inlets from colliding with the sealing gate plate 9 under the action of the reciprocating rod 21 and the pressure plate 27.
