Abstract
Description
Technical Field
[0001] This utility model relates to the field of kiln technology, and in particular to a layered independent multi-cavity replacement chamber. Background Technology
[0002] Lithium battery material production is usually carried out in a kiln sintering process. Because these materials have strict requirements on the concentration of the process atmosphere inside the kiln, gas replacement chambers are usually set at both ends of the kiln to ensure sufficient process atmosphere inside the kiln.
[0003] Previously, the replacement chambers of multi-layer saggers were all shared single cavities. The single-cavity design easily leads to uneven temperature distribution inside the furnace, with a large temperature difference between the top and bottom, which affects the stability of product quality. Furthermore, when process parameters (such as pressure and atmosphere) are adjusted, a chain reaction is easily generated, making it difficult to achieve precise control. In addition, each replacement will cause the entire production line to stop, affecting production efficiency. Utility Model Content
[0004] Based on the above problems, the purpose of this utility model is to provide a layered independent multi-cavity replacement chamber, improve the design of a single-cavity replacement chamber, and improve production quality and efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A layered independent multi-cavity replacement chamber includes a replacement chamber frame and a first chamber and a second chamber disposed on the replacement chamber frame. The first chamber and the second chamber are arranged in layers and are independent of each other. Several sealing doors are provided in the first chamber and the second chamber to divide the first chamber and the second chamber into multiple independent cavities. Each sealing door can be opened or closed independently.
[0007] As an optional solution, a sealed door includes a door frame, a door panel, a lifting mechanism, and a blocking mechanism, wherein:
[0008] A sealing port is provided between adjacent independent cavities, and the door frame is located on one side of each sealing port;
[0009] The door panel stands upright between the door frame and the sealing opening. The door panel and the door frame are hinged together by a connecting rod. Under normal conditions, the door panel is pressed against the door frame by gravity and forms a gap with the sealing opening.
[0010] The lifting mechanism is used to drive the door frame to rise or fall relative to the sealing opening, thereby driving the door panel to alternately switch between the open and closed positions. When the door panel is in the open position, it completely avoids the sealing opening, and when the door panel is in the closed position, it faces the sealing opening.
[0011] The blocking mechanism is used to limit the downward travel of the door panel when it is in the closed position, so that when the door frame descends again relative to the door panel, the door panel is pushed towards the sealing opening.
[0012] As an alternative, the lifting mechanism includes a screw jack, the output end of which is connected to the door frame. Lifting guide rails are provided on both sides of the door frame, and guide wheels that roll along the lifting guide rails are provided on the door frame.
[0013] As an alternative, the blocking mechanism includes a baffle that can alternately move to a blocking position and a yielding position. When the baffle is in the blocking position, it supports the bottom of the door panel, and when the baffle is in the yielding position, it yields to the movement path of the door panel.
[0014] As an alternative, the baffle is equipped with rollers that make rolling contact with the bottom of the door panel.
[0015] As an alternative, the first chamber is located above the second chamber, and the first chamber and the second chamber are adjacent to each other. The sealing door on the first chamber opens upward, and the sealing door on the second chamber opens downward.
[0016] As an alternative, the upper side of the first chamber and the lower side of the second chamber are respectively provided with an external convex cavity that accommodates a sealing door and communicates with the corresponding independent cavity, and an inspection port is provided on the external convex cavity.
[0017] As an alternative, each independent cavity is equipped with a separately driven conveyor roller, and the conveyor rollers on the same layer are connected in sequence to form a conveyor line.
[0018] The beneficial effects of this utility model are:
[0019] Compared with existing technologies, this layered independent multi-cavity replacement chamber has the following advantages:
[0020] 1) The layered chamber structure allows for independent speed adjustment based on different materials in each layer, ensuring a high yield rate;
[0021] 2) The sealed doors of each chamber can be opened or closed as needed, each independently and without interference;
[0022] 3) Each independent chamber has a small space, which allows for faster gas replacement and improves production efficiency;
[0023] 4) A failure in one chamber will not affect the operation of other chambers and will not cause the entire production line to stop. Attached Figure Description

Detailed Implementation
[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0032] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0033] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.
[0034] Please see Figures 1 to 3 As shown, this embodiment provides a layered independent multi-cavity replacement chamber, including a replacement chamber frame 1 and a first chamber 2 and a second chamber 3 disposed on the replacement chamber frame 1. The first chamber 2 and the second chamber 3 are arranged in layers and are independent of each other. A plurality of sealing doors 4 are respectively provided in the first chamber 2 and the second chamber 3 to divide the first chamber 2 and the second chamber 3 into multiple independent cavities 5. Each sealing door 4 can be opened or closed independently.
[0035] Therefore, a layered structure was designed to form multiple independent chambers 5, which can independently adjust the speed according to different materials, and replace the gas more quickly, ensuring the yield and production efficiency, meeting the usage requirements, and providing a new idea for the structural design of the replacement chamber.
[0036] Optionally, the sealed door 4 includes a door frame 41, a door panel 42, a lifting mechanism 43, and a blocking mechanism 44. A sealing opening 6 is provided between adjacent independent cavities 5, and the door frame 41 is located on one side of each sealing opening 6. The door panel 42 is erected between the door frame 41 and the sealing opening 6. The door panel 42 and the door frame 41 are hinged together by a connecting rod 45. In its natural state, the door panel 42 is pressed against the door frame 41 by gravity and forms a gap with the sealing opening 6. The lifting mechanism 43 is used to drive the door frame 41 to rise or fall relative to the sealing opening 6, thereby driving the door panel 42 to alternately switch between the open and closed positions. When the door panel 42 is in the open position, it completely avoids the sealing opening 6. When the door panel 42 is in the closed position, it faces the sealing opening 6. The blocking mechanism 44 is used to limit the downward stroke of the door panel 42 in the closed position, so that when the door frame 41 falls again relative to the door panel 42, the door panel 42 is pushed towards the sealing opening 6.
[0037] Therefore, a door panel 42 was designed to be hinged to the door frame 41 via a connecting rod 45. Through the cooperation of the lifting mechanism 43 and the blocking mechanism 44, the door panel 42 does not come into contact with the sealing port 6 of the replacement chamber during the switching between the open and closed positions. After reaching the closed position, it moves towards the sealing port 6 to achieve a tight seal. This ensures the airtightness of the replacement chamber cavity when the sealing door 4 is closed, and also ensures that the door panel 42 does not slide or rub during the lifting process, thus preventing the generation of metal powder that could interfere with the product composition and meeting the usage requirements.
[0038] Optionally, the lifting mechanism 43 includes a screw jack 431, the output end of which is connected to the door frame 41. Lifting guide rails 432 are provided on both sides of the door frame 41, and guide wheels 411 that roll along the lifting guide rails 432 are provided on the door frame 41.
[0039] Therefore, the screw jack 431 drives the door frame 41 to rise and fall, meeting the movement requirements, and the lifting guide rail 432 restricts the displacement of the door frame 41, ensuring the positional accuracy during the lifting process. In addition, the guide wheel 411 can reduce the sliding friction between the door frame 41 and the lifting guide rail 432 during the lifting process, ensuring that the door frame 41 rises and falls smoothly.
[0040] Optionally, the blocking mechanism 44 includes a baffle 441 that can alternately move to a blocking position and a yielding position. When the baffle 441 is in the blocking position, it supports the bottom of the door panel 42. When the baffle 441 is in the yielding position, it yields to the movement path of the door panel 42.
[0041] Specifically, a cylinder can drive a rotating rod, which in turn drives the baffle 441 to rotate, thereby switching between the blocking position and the avoidance position, and thus controlling the baffle 441 to limit or avoid the lower end of the door panel 42.
[0042] Furthermore, the baffle 441 is provided with a roller 442 that makes rolling contact with the bottom of the door panel 42.
[0043] Since there is still contact damage between the baffle 441 and the bottom of the door panel 42 when the door panel 42 moves toward the sealing opening 6, the roller 442 can greatly reduce wear and make the lateral movement of the door panel 42 smoother.
[0044] Optionally, the first chamber 2 is located above the second chamber 3, and the first chamber 2 and the second chamber 3 are adjacent to each other. The sealing door 4 on the first chamber 2 opens upward, and the sealing door 4 on the second chamber 3 opens downward.
[0045] Therefore, the sealing door 4 of the first chamber 2 and the sealing door 4 of the second chamber 3 do not interfere with each other during opening or closing, which meets the usage requirements, and the difference between opening downward and opening upward only requires adaptive adjustment of the action of the lifting mechanism 43.
[0046] Furthermore, the upper side of the first chamber 2 and the lower side of the second chamber 3 are respectively provided with an externally protruding cavity 7 that accommodates the sealing door 4 and communicates with the corresponding independent cavity 5, and an inspection port 8 is provided on the externally protruding cavity 7.
[0047] Therefore, the design of the convex cavity 7 facilitates the maintenance and repair of the sealing door 4, ensuring long-term reliability. Furthermore, the layered and independent design of the first chamber 2 and the second chamber 3 allows for quick repair of a single sealing door 4 without downtime, thus improving overall work efficiency.
[0048] Optionally, each independent cavity 5 is provided with a separately driven conveyor roller 9, and the conveyor rollers 9 on the same layer are connected in sequence to form a conveyor line.
[0049] Therefore, each independent cavity 5 can be set with an independent conveying speed, and the conveyor line of each layer can be independently adjusted according to different materials in each layer to meet more usage needs and ensure a high yield rate.
[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
