AI Technical Summary
Existing moisture content testing devices rotate concrete blocks during testing to improve heating efficiency. While rotation does increase heating efficiency, the concrete inside the container still dries faster near the heat source than away from it, resulting in low overall heating and drying efficiency.
The system employs a vortex-shaped heater and a turning component. The vortex-shaped heater increases the contact area at the bottom of the container, while the turning component uses a servo motor-driven movable rod and turning blades to turn the clay, ensuring that the upper and lower layers of clay are heated evenly. Combined with a weighing sensor, the system is used to calculate the moisture content.
This method achieves uniform heating of the upper and lower clay layers during the clay heating process, improving the overall heating efficiency. Furthermore, it accurately calculates the moisture content using a weighing sensor, thus solving the problem of low efficiency caused by uneven heating.

Description
Technical Field
[0001] This utility model relates to the field of clay moisture content determination technology, specifically a clay moisture content measuring machine. Background Technology
[0002] Clay, as an important natural resource, plays a vital role in many fields such as construction, ceramics, agriculture, and environmental protection. However, the properties and uses of clay largely depend on its moisture content. Moisture content not only affects the plasticity and formability of clay but also relates to the physical and chemical changes during its drying and firing processes. Therefore, accurate and rapid determination of clay moisture content is of great significance for ensuring product quality, optimizing production processes, and reducing production costs. The most common method for determining clay moisture content is the thermogravimetric method, which determines the moisture content by measuring the mass loss of the sample during the heating process.
[0003] For example, a concrete moisture content testing device with announcement number CN216870270U includes a testing box, a heating box installed at the lower end of one side of the testing box, a circulating fan installed on one side inside the heating box, a heating pipe installed inside the heating box on the side of the circulating fan, and a pressure sensor body installed at an equal angle at the bottom of the fixed base, and a testing platform installed between the tops of the pressure sensor bodies.
[0004] The existing technology has the following technical problems: When the existing moisture content detection device performs the test, in order to improve the heating efficiency of the test object, the concrete block is rotated. Although the rotation can improve the heating efficiency, the concrete inside the container will still dry faster than the concrete away from the heat source, resulting in low overall heating and drying efficiency.
[0005] Therefore, we propose a clay moisture content measuring machine to solve the problems mentioned above. Utility Model Content
[0006] The purpose of this invention is to provide a clay moisture content tester to solve the problem mentioned in the background art that existing moisture content testing devices on the market, in order to improve the heating efficiency of the test object, rotate the concrete block. Although rotation can improve the heating efficiency, the concrete inside the container still dries faster near the heat source than the concrete far from the heat source, resulting in low overall heating and drying efficiency.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a comparative clay moisture content tester, comprising a workbench and a weighing sensor installed in the middle of the workbench. Support plates are provided on both the left and right sides of the weighing sensor, and heaters are installed on the support plates. A container is placed above the heaters. Different types of clay are placed on the left and right support plates for comparative heating and testing. Limiting components are installed on the sides of the support plates to limit the position of the container. A turning component is installed in the middle of the container to improve the heating and drying efficiency of the clay during heating.
[0008] Preferably, the heater is embedded in the support plate and the heater is configured as a vortex structure.
[0009] By adopting the above technical solution and using a heater with a vortex-shaped structure, the contact area with the bottom of the container can be increased.
[0010] Preferably, the limiting component includes a clamping block, and an adjusting screw is installed in the middle of the clamping block, and a guide rod fixed to the side of the clamping block is installed through the bearing plate.
[0011] By adopting the above technical solution, the screw-connected clamping block can be moved by adjusting the rotation of the screw.
[0012] Preferably, the middle part of the clamping block and the adjusting screw are threadedly connected, and the guide rod on the side of the clamping block can slide on the bearing plate.
[0013] By adopting the above technical solution, the sliding of the side guide rod of the clamping block on the bearing plate can prevent the clamping block from rotating synchronously with the adjusting screw.
[0014] Preferably, the material-turning component includes a movable rod, and a material-turning blade is fixed circumferentially on the movable rod. The lower end of the movable rod is connected to a central shaft, and the central shaft is rotatably connected to the middle of the container. The lower end of the central shaft is provided with a slot, and a plug is inserted into the slot. The plug is fixed to the output end of the servo motor.
[0015] By adopting the above technical solution, the rotation of the movable rod can cause the circumferential turning blades to turn the clay to be heated.
[0016] Preferably, the lower end of the movable rod and the upper end of the central shaft are threaded together, and the movable rod has evenly distributed turning blades in the circumference.
[0017] By adopting the above technical solution, the movable rod and the central shaft are connected by a thread, making it easy to remove the movable rod from the central shaft.
[0018] Preferably, the outer wall of the insert block and the inner wall of the slot at the lower end of the central shaft fit together, and the cross-section of the insert block is set as a "+" shaped structure, and the lower end of the central shaft is flush with the bottom of the container.
[0019] By adopting the above technical solution, the stability of the two after insertion can be improved by the mutual contact between the outer wall of the insert block and the inner wall of the slot, and the central shaft can be driven to rotate synchronously when the output shaft of the servo motor rotates.
[0020] Compared with the prior art, the beneficial effects of this utility model are: when drying clay, the clay moisture content measuring machine turns the clay inside the container, so that the upper and lower layers of clay can be heated evenly, thereby improving the overall heating efficiency of the clay.
[0021] 1. A weighing sensor is set up. The weight of the container and the turning part in the initial state can be recorded as K1. The total weight of the container and the turning part after the clay is filled is K2. The weight of the container after the clay is heated is recorded as K3. The moisture content can be obtained by calculating the difference between the weights.
[0022] 2. A heater is provided. The vortex-shaped heater can increase the contact area between the bottom of the container and the heater. At the same time, the rotation of the adjusting screw can move the clamp towards the container, thereby clamping and fixing the container.
[0023] 3. Equipped with a turning blade, the servo motor can be activated by the cooperation of the insert block and the slot, which causes the central shaft to drive the movable rod to rotate. The rotation of the movable rod can then cause the turning blade to turn the clay inside the container, thereby improving the heating and drying efficiency of the clay.
[0024] 4. It is equipped with a support plate. The symmetrically distributed support plates make it easy to heat different types of clay at the same time, thereby enabling comparative testing of two different types of clay. Attached Figure Description

[0031] 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.
[0032] Example 1: Please refer to Figures 1-5 Existing moisture content testing devices, in order to improve the heating efficiency of the tested material, rotate the concrete block during measurement. Although rotation can improve heating efficiency, the concrete inside the container still dries faster near the heat source than the concrete farther away, resulting in low overall heating and drying efficiency. To solve the above technical problem, this embodiment discloses the following technical content: a comparative clay moisture content tester, including a workbench 1 and a weighing sensor 2 installed in the middle of the workbench 1. Support plates 3 are provided on both sides of the weighing sensor 2, and heaters 4 are installed on the support plates 3. A container 6 is placed above the heaters 4. The support plate 3 is used to place different types of clay for comparative heating and testing. A limiting component 5 is installed on the side of the support plate 3, and the limiting component 5 is used to limit the container 6. A turning component 7 is installed in the middle of the container 6 to improve the heating and drying efficiency of the clay when heating. The heater 4 is embedded in the support plate 3 and is set as a vortex structure. The limiting component 5 includes a clamping block 501, and an adjusting screw 502 is installed in the middle of the clamping block 501. A guide rod 503 fixed on the side of the clamping block 501 is installed through the support plate 3. The middle of the clamping block 501 and the adjusting screw 502 are threadedly connected, and the guide rod 503 on the side of the clamping block 501 can slide on the support plate 3.
[0033] When testing the moisture content of the clay, the container 6 and the turning component 7 are placed on the weighing sensor 2 and weighed to obtain the weight result K1. Then, the container 6 is filled with clay and weighed to obtain the weight result K2. The weighed container 6 is placed on the support plate 3, and the adjusting screw 502 is rotated. After the adjusting screw 502 rotates, the threaded clamping block 501 moves towards the container 6, thereby clamping the container 6. The heater 4 is then turned on to heat the clay inside the container 6. The clay is heated to evaporate its moisture. During the heating process, the clay in the container 6 is effectively turned over by the turning component 7 inside the container 6, so that the upper and lower layers of clay can be heated evenly, improving the heating efficiency of the clay. After the clay is heated, the container 6 is placed back on the weighing sensor 2 for weighing, and the weight result K3 is obtained. The weight of the clay in the initial state is obtained by k2-K1, and the weight of the dried clay is obtained by k3-k1. Finally, the moisture content of the clay can be obtained by calculation formula, thus realizing the determination of the moisture content of the clay.
[0034] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. The following technical content is disclosed in this example: the material turning component 7 includes a movable rod 701, and a material turning blade 702 is fixed circumferentially on the movable rod 701. The lower end of the movable rod 701 is connected to a central shaft 703, and the central shaft 703 is rotatably connected to the middle of the container 6. The lower end of the central shaft 703 is provided with a slot 704, and a plug 705 is inserted into the slot 704. The plug 705 is fixed on the output end of the servo motor 706. The lower end of the movable rod 701 and the upper end of the central shaft 703 are threadedly connected. The material turning blades 702 are evenly distributed circumferentially on the movable rod 701. The outer wall of the plug 705 and the inner wall of the slot 704 at the lower end of the central shaft 703 fit together. The cross-section of the plug 705 is set as a "+" shaped structure. The lower end of the central shaft 703 and the bottom of the container 6 are flush with each other.
[0035] After the container 6 is placed on the support plate 3, the slot 704 at the lower end of the central shaft 703 on the container 6 is engaged with the plug 705 on the output shaft of the servo motor 706. When the servo motor 706 is turned on, it can drive the central shaft 703 to rotate using the plug 705. The rotation of the central shaft 703 drives the movable rod 701 to rotate. The rotation of the movable rod 701 can then effectively turn the heated clay inside the container 6 using the circumferential turning blades 702, thereby improving the heating efficiency of the clay. At the same time, the movable rod 701 and the central shaft 703 are connected by threads, which makes it easy to remove the movable rod 701 from the central shaft 703 later, facilitating the cleaning of the movable rod 701 and the inside of the container 6.
[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
