Description

Technical Field

[0001] This utility model relates to the field of total moisture testing technology, and in particular to an oven device for total moisture testing. Background Technology

[0002] In the process of total moisture testing, sample drying and sample weight verification are the two most important steps. During the test, the sample tray needs to be transferred between the weighing mechanism and the drying oven mechanism. Especially in the inspection drying step, it is necessary to verify whether the sample has reached constant weight (i.e., complete removal of moisture) by repeating the cycle of drying and weighing.

[0003] In existing full moisture testing systems (such as CN119044516A), the distance between the weighing mechanism and the drying oven mechanism is relatively far. The transfer robot needs to make long-distance transfers, resulting in low transfer efficiency. Furthermore, due to the long distance, there is a high risk of samples falling off the sample tray during the transfer process, leading to large errors in the test results. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an oven device for total moisture testing with high transfer efficiency and small test result error.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] An oven apparatus for total moisture testing includes a frame, on which an oven mechanism, a sample tray storage mechanism, and a weighing mechanism are provided. The oven mechanism is used to dry the sample in the sample tray, the sample tray storage mechanism is used to temporarily store and cool the sample tray, and the weighing mechanism is used to weigh the sample tray.

[0007] As a further improvement to the above technical solution:

[0008] The oven mechanism includes multiple independently configured ovens.

[0009] The oven includes a box body with an opening and a door at the opening. The door is hinged to the box body, and the box body is provided with an opening and closing drive assembly for driving the door to open and close.

[0010] The opening and closing drive assembly includes an opening and closing drive component, a first connecting rod, and a second connecting rod. The first connecting rod is hinged to the door, and the second connecting rod is hinged to the body. The first connecting rod and the second connecting rod are hinged together. The opening and closing drive component is located on the body and connected to the first connecting rod.

[0011] A sealing element is provided between the door and the opening of the box body.

[0012] The enclosure is also equipped with a clamping drive assembly for pressing the enclosure door against the enclosure.

[0013] The clamping drive assembly includes a rotary clamping cylinder and a clamping block. The rotary clamping cylinder is located on the housing and connected to the clamping block to drive the clamping block to clamp onto the housing door.

[0014] The enclosure is equipped with an air inlet and a nitrogen inlet for connecting to an external nitrogen equipment. The air inlet is equipped with a one-way valve.

[0015] The frame is also equipped with an exhaust condensation pipe, and the chamber is also equipped with an exhaust port. The chamber is equipped with a fan for realizing gas circulation in the oven and discharging the gas in the oven through the exhaust port. The exhaust ports of each chamber are connected to the exhaust condensation pipe.

[0016] The sample storage mechanism includes multiple storage sections arranged at intervals.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] 1. The oven device for total moisture testing of this utility model integrates the oven mechanism, sample tray storage mechanism and weighing mechanism into the same device, which reduces the transfer distance of the sample tray, has high transfer efficiency, reduces the risk of samples falling out of the sample tray, and has small test result error.

[0019] 2. The oven device for total moisture testing of this utility model has each oven set independently. Each oven can independently adjust its temperature and oven atmosphere. Independent temperature adjustment can avoid the problems of excessive volume and low temperature control accuracy of traditional single large ovens. Independent oven atmosphere adjustment can introduce atmospheric gas only into the oven that needs to work, resulting in high energy utilization efficiency. Different atmospheric gases can be introduced into different ovens, making it highly adaptable.

[0020] 3. The oven device for total moisture testing of this utility model opens and closes the oven door by driving the opening and closing drive component, which saves time and effort and has a high degree of automation.

[0021] 4. In the oven device for total moisture testing of this utility model, after the oven door is closed, the pressing drive assembly presses the oven door onto the oven body to prevent the oven door from lifting due to the elasticity of the sealing element, thus improving the sealing performance.

[0022] 5. The oven device for total moisture testing of this utility model retracts the rotating clamping cylinder after the oven door is closed, driving the pressing block to press against the oven door, thereby achieving the pressing of the oven door; when the oven door is opened, the rotating clamping cylinder extends, and then drives the pressing block to rotate to avoid it, thereby releasing the pressing of the oven door. The structure is simple and reliable.

[0023] 6. The oven device for total moisture testing of this utility model, when using an air atmosphere for drying, draws dry air into the oven through the air inlet; when using a nitrogen atmosphere for drying, an external nitrogen device injects nitrogen into the oven through the nitrogen inlet. Since a one-way valve is provided on the air inlet, nitrogen will not be discharged into the room from the air inlet. By controlling the on / off of nitrogen, the switching between nitrogen atmosphere and air atmosphere inside the oven can be realized. The structure is simple and reliable.

[0024] 7. The oven device for total moisture testing of this utility model uses a fan to drive the gas inside the oven to be discharged from the exhaust port, so that a negative pressure is formed inside the oven, which draws in air or accelerates the internal circulation of nitrogen. The humid air or humid nitrogen after drying the sample is discharged into the exhaust condensation pipe through the exhaust port. The condensate flows to the bottom of the gas condensation pipe, and the gas is discharged from the top of the condensation pipe to the external pipe, thus realizing gas-liquid separation.

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not 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.

[0038] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" 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 according to the specific circumstances.

[0040] like Figures 1 to 10As shown, the oven apparatus for total moisture testing in this embodiment includes a frame 1, on which an oven mechanism 2, a sample tray storage mechanism 3, and a weighing mechanism 4 are mounted. The oven mechanism 2 is used to dry the sample in the sample tray 9, the sample tray storage mechanism 3 is used to temporarily store and cool the sample tray 9, and the weighing mechanism 4 is used to weigh the sample tray 9. In this embodiment of the oven apparatus for total moisture testing, an external transfer device places the sample tray 9 containing the sample to be tested into the weighing mechanism 4 for weighing. After weighing, the sample tray 9 is transferred to the oven mechanism 2 for drying. After drying, the sample tray 9 is transferred to the sample tray storage mechanism 3 for temporary storage and cooling. After cooling, the sample tray 9 is transferred to the weighing mechanism 4 for weighing again. When it is necessary to perform check drying on the sample, the above operation is repeated to achieve constant weight verification of the sample. The oven apparatus for total moisture testing in this embodiment integrates the oven mechanism 2, the sample tray temporary storage mechanism 3, and the weighing mechanism 4 into the same device, reducing the transfer distance of the sample tray 9, resulting in high transfer efficiency, reducing the risk of samples falling out of the sample tray 9, and minimizing test result errors.

[0041] Furthermore, such as Figures 1 to 5 As shown in this embodiment, the oven mechanism 2 includes multiple independently configured ovens 5. With each oven 5 independently configured, the temperature and atmosphere of each oven 5 can be independently adjusted. Independent temperature adjustment avoids the problems of excessive size and low temperature control accuracy inherent in traditional single large ovens. Independent atmosphere adjustment allows for the introduction of atmospheric gas only into the oven 5 that needs to operate, resulting in high energy efficiency. Furthermore, different atmospheric gases can be introduced into different ovens 5, demonstrating strong adaptability.

[0042] Preferably, in this embodiment, the number of ovens 5 can be flexibly adjusted according to needs. For example... Figure 4 As shown, increasing the number of ovens 5 also increases the number of sample tray storage mechanisms 3.

[0043] Furthermore, such as Figures 6 to 10 As shown, in this embodiment, the oven 5 includes a chamber 51, an opening on the chamber 51, and a door 52 at the opening. The door 52 is hinged to the chamber 51, and an opening and closing drive assembly 53 is provided on the chamber 51 for driving the door 52 to open and close. The door 52 is opened and closed by driving the opening and closing drive assembly 53, which saves time and effort and has a high degree of automation.

[0044] Furthermore, in this embodiment, the opening and closing drive assembly 53 includes an opening and closing drive member 531, a first connecting rod 532 and a second connecting rod 533. The first connecting rod 532 is hinged to the door 52, and the second connecting rod 533 is hinged to the housing 51. The first connecting rod 532 and the second connecting rod 533 are hinged together. The opening and closing drive member 531 is disposed on the housing 51 and connected to the first connecting rod 532. When closing the door 52, the telescopic end of the opening and closing drive component 531 (such as a cylinder, hydraulic cylinder, or electric push rod) extends forward, causing one end of the first connecting rod 532 to rotate around the second connecting rod 533. The other end of the first connecting rod 532 presses against the door 52, causing the door 52 to close. When opening the door 52, the telescopic end of the opening and closing drive component 531 retracts backward, causing one end of the first connecting rod 532 to rotate around the second connecting rod 533 in the opposite direction to the rotation direction when closing the door 52. The other end of the first connecting rod 532 pulls the door 52 to open. The opening and closing process is simple.

[0045] Preferably, in this embodiment, the door 52 is hinged to the box body 51 by two hinges, and the first connecting rod 532 and the door 52, the second connecting rod 533 and the box body 51, and the first connecting rod 532 and the second connecting rod 533 are all hinged by pins, which makes the structure simple and reliable.

[0046] Furthermore, in this embodiment, a sealing element 55 is provided between the door 52 and the opening of the box body 51. After the door 52 is closed, the sealing element 55 (e.g., a sealing ring) seals the opening between the door 52 and the box body 51, preventing the leakage of atmospheric gas inside the box body 51. The structure is simple and reliable.

[0047] Furthermore, in this embodiment, the housing 51 is also provided with a pressing drive assembly 54 for pressing the door 52 onto the housing 51. After the door 52 is closed, the pressing drive assembly 54 presses the door 52 onto the housing 51 again, preventing the door 52 from lifting due to the elasticity of the seal 55, thus improving the sealing performance.

[0048] Furthermore, in this embodiment, the clamping drive assembly 54 includes a rotary clamping cylinder 541 and a clamping block 542. The rotary clamping cylinder 541 is mounted on the housing 51 and connected to the clamping block 542 to drive the clamping block 542 to clamp onto the housing door 52. After the housing door 52 is closed, the rotary clamping cylinder 541 retracts, causing the clamping block 542 to clamp onto the housing door 52, thus clamping the housing door 52. When the housing door 52 is opened, the rotary clamping cylinder 541 extends, and then drives the clamping block 542 to rotate to avoid it, releasing the clamping of the housing door 52. The structure is simple and reliable.

[0049] Preferably, in this embodiment, the door 52 is provided with a groove 521, and the pressing block 542 is pressed into the groove 521, so that the pressing block 542 will not protrude from the surface of the door 52, avoiding interference between the pressing block 542 and other equipment, and is more aesthetically pleasing.

[0050] Furthermore, in this embodiment, the chamber 51 is provided with an air inlet 512 and a nitrogen inlet 513 for connecting to an external nitrogen equipment. The air inlet 512 is provided with a one-way valve 514. When drying is performed using an air atmosphere, drying air is drawn into the chamber 51 through the air inlet 512. When drying is performed using a nitrogen atmosphere, the external nitrogen equipment injects nitrogen into the chamber 51 through the nitrogen inlet 513. Since the air inlet 512 is provided with a one-way valve 514, nitrogen will not be discharged into the room through the air inlet 512. By controlling the flow of nitrogen, the switching between nitrogen atmosphere and air atmosphere inside the oven 5 can be realized. The structure is simple and reliable.

[0051] Furthermore, in this embodiment, the frame 1 is also provided with an exhaust condensation pipe 6, and the chamber 51 is also provided with an exhaust port 515. The chamber 51 is provided with a fan 516 for realizing gas circulation in the oven 5 and discharging the gas in the oven 5 through the exhaust port 515. The exhaust port 515 of each chamber 51 is connected to the exhaust condensation pipe 6. The fan 516 drives the gas in the oven 5 to be discharged from the exhaust port 515, so that a negative pressure is formed in the chamber 51, which draws in air or accelerates the internal circulation of nitrogen. The humid air or humid nitrogen after drying the sample is discharged into the exhaust condensation pipe 6 through the exhaust port 515. The condensate flows to the bottom of the exhaust condensation pipe 6, and the gas is discharged from the top of the exhaust condensation pipe 6 to the external pipe, thus realizing gas-liquid separation.

[0052] Preferably, in this embodiment, a condensate valve is provided at the bottom of the exhaust condensate pipe 6 to facilitate the collection and treatment of condensate.

[0053] Furthermore, in this embodiment, the sample tray temporary storage mechanism 3 includes multiple storage sections 31 spaced apart. The multiple storage sections 31 are spaced apart, so that the sample trays 9 are stored separately, avoiding the slow cooling problem caused by traditional stacking storage methods and improving cooling efficiency.

[0054] Preferably, in this embodiment, the weighing mechanism 4 includes a leveling mechanism and a balance. The sample pan 9 is first leveled by the leveling mechanism before being weighed and dried, resulting in more uniform drying and a better drying effect.

[0055] Preferably, in this embodiment, the frame 1 is also equipped with a control cabinet, which is connected to each component via signal, enabling the device to automatically control the opening and closing of the oven 5, the regulation of nitrogen flow, the emission of moisture and the leveling process, thereby achieving efficient management of the drying, leveling and weighing processes, reducing human intervention and improving overall efficiency and accuracy.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of the present utility model using the methods and techniques disclosed above, or modify it into equivalent embodiments with equivalent changes, without departing from the spirit and technical solution of the present utility model.
