Description

Technical Field

[0001] This utility model relates to the field of weighing test chamber technology, and more specifically, to an automatic conveying and isolation structure for a high and low temperature test chamber of an evaporation residual weight system. Background Technology

[0002] The Evaporation Residual Weight Tester is a fully automatic weighing system that weighs various samples such as gaseous particles, water samples, food, and solid waste, as well as various carriers such as crucibles, evaporating dishes, filter membranes, filter cartridges, and low-concentration sampling heads, within a constant temperature and humidity sealed chamber.

[0003] Currently, with the development of technology, stable automatic transfer of test samples during the transfer process in the high and low temperature test chamber of the evaporation residual weight system cannot be achieved, which reduces the convenience of use. Furthermore, since the test samples need to be transferred inside the testing device, the connection between the various high and low temperature test chambers cannot be effectively sealed and isolated after the transfer is completed, thereby reducing the accuracy of the test data. To address these issues, we have designed an automatic transfer and isolation structure for the high and low temperature test chamber of the evaporation residual weight system. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide an automatic conveying and isolation structure for the high and low temperature test chamber of an evaporation residual weight system. This automatic conveying and isolation structure for the high and low temperature test chamber of the evaporation residual weight system, through the setting of a lifting shaft, sample tray and evaporation dish, enables the test sample to be automatically conveyed to the drying chamber or test chamber according to the test needs, which greatly improves the convenience of use. Furthermore, through the setting of a top plate, bottom plate and sealing ring, the drying chamber and test chamber are isolated after the test sample enters the drying chamber or the test chamber, ensuring the accuracy of the test data.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] An automatic conveying and isolation structure for a high and low temperature test chamber of an evaporation residual weight system includes a complete machine consisting of a drying chamber, a test chamber, and a control chamber from top to bottom. A through hole is provided between the drying chamber and the test chamber, and two sealing rings are fixed at the through hole. Three sets of lifting and rotating mechanisms are installed on the bottom plate of the test chamber, namely slide module a, slide module b, and slide module c, and all three are located in the control chamber. The slider of the slide module a is equipped with a rotating shaft a, and a top plate and a bottom plate are fixed on the rotating shaft a, with several trays for placing evaporating dishes fixed between them. The top plate and the bottom plate can respectively contact and press with the upper and lower sealing rings. The slider of the slide module b is equipped with a rotating shaft b, a transfer plate is fixed to the top of the rotating shaft b, and a plate capable of supporting the evaporation dish is provided at the end of the transfer plate. The slide module c has a rotating shaft c installed on its slider. A horizontal shaft is installed on the top of the rotating shaft c and a windproof cover is fixed on the horizontal shaft. A weighing device is installed inside the test chamber.

[0007] Furthermore, sheet metal a and sheet metal b are fixed at the top and bottom of the through hole between the drying chamber and the test chamber, respectively. A circular positioning plate is fixed between the two by bolts. The sealing ring is hollow and has an arc-shaped top and an outward-facing circular slit at the bottom. The circular slits of the upper and lower sealing rings are respectively engaged with sheet metal a and the positioning plate, and the lower sealing ring abuts against sheet metal b.

[0008] Furthermore, the slide module a can control the rotating shaft a to move up and down, and the motor a on its slider controls the rotating shaft a to rotate freely, thereby controlling the rotation of the tray.

[0009] Furthermore, the slide module b can control the rotating shaft b to move up and down, and the motor b on the slider controls the rotating shaft b to rotate freely. Each tray is provided with several sets of ports arranged in a circle, and several locking cones are provided around each port. The locking cones can engage with the evaporating dish.

[0010] Furthermore, each port on the tray has an outward-facing opening through which the panel can pass and mate with the port on the tray.

[0011] Furthermore, the end of the panel that supports the evaporating dish is provided with a through-hole ring with an opening. The weighing device is provided with a weighing support for placing the evaporating dish. The diameter of the ring is larger than the diameter of the weighing support, and the opening of the ring is larger than the diameter of the support rod of the weighing support.

[0012] Furthermore, the slide module c can control the rotating shaft c to move up and down, and the motor c on the slider controls the rotating shaft c to rotate freely.

[0013] Furthermore, the diameters of both the top plate and the bottom plate are larger than the diameter of the tray, so that the tray does not come into contact with the sealing ring when the rotating shaft a moves up and down.

[0014] Furthermore, the top and bottom plates are made of mica sheets, and the two sealing rings are symmetrically arranged.

[0015] Compared with existing technologies, the advantages of this utility model are: (1) This scheme, through the setting of lifting shaft, sample tray and evaporating dish, enables the test sample to be automatically transferred to the drying chamber or test chamber according to the test needs, which greatly improves the convenience of using the test chamber.

[0016] (2) This scheme ensures the accuracy of test data by setting up a top plate, a chassis and a sealing ring so that the test sample is isolated in the drying chamber or the test chamber after entering the drying chamber or the test chamber.

[0017] (3) This utility model uses a three-linkage sliding table module to automatically weigh multiple evaporating dishes in sequence, which greatly reduces the degree of manual intervention and improves the degree of automation. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-7 An automatic conveying and isolation structure for a high and low temperature test chamber of an evaporation residual weight system is disclosed. The system comprises a drying chamber 1, a test chamber 2, and a control chamber 3, arranged from top to bottom. A through-hole connects the drying chamber 1 and the test chamber 2, allowing test samples to be moved upwards to the drying chamber 1 for drying or downwards to the test chamber 2 for weighing. The control chamber 3 contains conventional electrical control components such as a PLC and a switching power supply. The drying components in the drying chamber 1 are conventionally configured, which is existing technology and will not be described in detail here. Two sealing rings 702 are fixed at the through-hole. Three lifting and rotating mechanisms are installed on the bottom plate 9 of the test chamber 2: a slide module a4, a slide module b5, and a slide module c6, all located within the control chamber 3. A fixing plate 901 is installed on the plate 9 for mounting existing components such as bushings. Those skilled in the art are familiar with the assembly and installation methods of slide modules; this invention only provides a brief overview of existing technology.

[0022] The slider of the slide module a4 is equipped with a rotating shaft a402. A top plate 7 and a bottom plate 701 are fixed on the rotating shaft a402, and several trays 801 for placing evaporating dishes 8 are fixed between the two. The top plate 7 and the bottom plate 701 can respectively contact and compress with the upper and lower sealing rings 702 to achieve the sealing of the drying chamber 1 and the test chamber 2. Of course, those skilled in the art should know that the temperature of the two can be cross-linked during the displacement process, but due to the presence of the ventilation component (existing technology, omitted), it will not affect the value. The slider of the slide module b5 is equipped with a rotating shaft b502, and a transfer plate 804 is fixed on the top of the rotating shaft b502. The end of the transfer plate 804 is provided with a plate 803 that can support the evaporating dish 8. The slider of the slide module c6 is equipped with a rotating shaft c602. A horizontal shaft 603 is installed on the top of the rotating shaft c602, and a windproof cover 604 is fixed on the horizontal shaft 603 to cover the evaporating dish 8 for weighing. The test chamber 2 is equipped with a weighing device 10.

[0023] Sheet metal a704 and sheet metal b705 are fixed at the top and bottom of the through hole between the drying chamber 1 and the test chamber 2, respectively. A circular positioning plate 703 is fixed between them by bolts. The sealing ring 702 is hollow and has an arc-shaped top. This design facilitates compression deformation to achieve sealing. The bottom has an outward-facing circular slit. The circular slits of the upper and lower sealing rings 702 are respectively engaged in sheet metal a704 and positioning plate 703. The lower sealing ring 702 abuts against sheet metal b705.

[0024] The slide module a4 can control the rotating shaft a402 to move up and down. As the main mechanism for conveying and sealing, the motor a401 on its slider controls the rotating shaft a402 to rotate freely, thereby controlling the tray 801 to rotate. Thus, each layer and each test evaporating dish 8 can be picked up and tested in turn.

[0025] The slide module b5 can control the rotating shaft b502 to move up and down, and the motor b501 on the slider controls the rotating shaft b501 to rotate freely. Each tray 801 is provided with several sets of ports arranged in a circle, and several locking cones 802 are provided around each port. The locking cones 802 can be engaged with the evaporating dish 8. The diameter of the locking cones 802 gradually increases from top to bottom, which is conducive to the placement of the evaporating dish 8. Of course, the two can be engaged by a gap fit to achieve the limiting.

[0026] Each port on the tray 801 has an outward opening, through which the panel 803 can pass (to prevent interference) and fit into the port on the tray 801, thereby supporting the evaporating dish 8.

[0027] The end of the panel 803 is provided with a through-hole 8031 ​​at the position where the evaporating dish 8 is supported. The through-hole 8031 ​​also has an opening. The weighing device 10 is provided with a weighing support 1001 for placing the evaporating dish 8. The diameter of the through-hole 8031 ​​is larger than the diameter of the weighing support 1001, and the opening of the through-hole 8031 ​​is larger than the diameter of the support rod of the weighing support 1001, so as to facilitate rotation and prevent interference.

[0028] The slide module c6 can control the rotating shaft c602 to move up and down, and the motor c601 on the slider controls the rotating shaft c601 to rotate freely. It can be linked with the slide module b5 and move together with the evaporating dish 8 when it is taken off the tray 801.

[0029] The diameters of the top plate 7 and the bottom plate 701 are both larger than the diameter of the tray 801. When the rotating shaft a402 moves up and down, the tray 801 does not come into contact with the sealing ring 702.

[0030] The top plate 7 and the bottom plate 701 are made of mica sheets, which serve as excellent thermal insulation materials; the two sealing rings 702 are symmetrically arranged vertically, making them easy to be squeezed from above and below.

[0031] Of course, those skilled in the art also know that by debugging the PLC program to control the speed of the three motors and the displacement speed of the three slide components, materials can be prevented from overflowing outside the evaporating dish or other test trays.

[0032] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
