Description
Technical Field
[0001] This utility model relates to the technical field of machine-made aggregate testing equipment, specifically to a device for testing the chemical composition of machine-made aggregate. Background Technology
[0002] In order to standardize the production and application of manufactured aggregates, a series of tests, including chemical composition and physical properties, are required after the manufactured aggregates are produced to ensure that they meet relevant regulations.
[0003] Traditional techniques for chemical testing of machine-made aggregates mainly include chemical analysis and colorimetry. Chemical analysis is slow and cumbersome for analyzing multiple components in complex samples, requiring highly skilled operators. Colorimetry has relatively poor selectivity and is easily interfered with by other colored substances or substances that can react with the reagents. It also requires high-level sample pretreatment, and its accuracy depends on the plotting of the standard curve and the stability of the measurement conditions. Furthermore, traditional chemical testing methods for manufactured aggregates only consider standalone applications. Therefore, the design of chemical testing devices for manufactured aggregates focuses solely on the chemical testing process and the resulting information, neglecting the actual usage scenarios. However, the application environments for chemical composition testing devices for manufactured aggregates are diverse. They can be used to test manufactured aggregates during the production process, immediately after production, or before use. The placement of the manufactured aggregates in these scenarios varies significantly. Testing of manufactured aggregates requires transferring them to the appropriate location within the testing device before testing can begin. Therefore, traditional testing devices for chemical composition testing of manufactured aggregates rely on manual placement of the sample or additional complex mechanical and electrical control procedures to transfer the sample to the designated location. Thus, designing a chemical composition testing device for manufactured aggregates that can adapt to various scenarios has become an urgent problem for enterprises in their production processes. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide a chemical composition detection device for machine-made aggregates, so as to solve the problem of low convenience and stability of the overall conveying process for chemical composition detection of existing machine-made aggregates.
[0005] To achieve the above objectives, this utility model utilizes a vacuum device to conveniently and stably transport the aggregate to be tested to a designated location, and acquires the necessary data using a detection lens to detect the chemical composition of the aggregate. Specifically, the device includes: a vacuum extractor, a vacuum feeding pipe, a transmission mechanism, a detection box mounted on the transmission mechanism, a leveling roller positioned above one end of the transmission mechanism, and a detection lens positioned above the other end of the transmission mechanism. One end of the vacuum extractor is connected to a storage device for the aggregate sample to be tested, and the other end is connected to the vacuum feeding pipe. The other end of the vacuum feeding pipe extends to the top of the detection box, allowing the vacuum extractor to acquire the aggregate sample to be tested and the vacuum feeding pipe to transport the sample into the detection box.
[0006] Its beneficial effects are as follows: By setting up a vacuum extractor combined with a vacuum feeding pipe, with the other end of the vacuum feeding pipe leading to the testing container, during use, only the other end of the vacuum extractor needs to be connected to the device capable of acquiring the aggregate sample to be tested. The vacuum extractor can then extract the aggregate sample stored in the original device into the vacuum feeding pipe of this device, and then transport the aggregate sample to be tested to the testing container through the vacuum feeding pipe of this device. Therefore, this invention solves the problem of inconvenient transportation caused by the need for manual placement of the sample in the designated position during testing in existing technologies. Furthermore, this invention also includes a transmission mechanism that can move the testing container between the sample acquisition end and the testing end, eliminating the need for manual placement of the testing container after sample acquisition, making the testing process more convenient. The device of this invention includes a detection lens, which is used to acquire information about the sample to be tested, so as to obtain the chemical composition test results of the machined aggregate based on the acquired information. Compared with chemical analysis and colorimetric methods, the device of this invention can automatically acquire the required information (the information acquired by the detection lens to obtain the chemical composition test results of the machined aggregate), and improves the convenience and stability of the overall conveying process.
[0007] Furthermore, the detection lens is an X-ray detection lens.
[0008] The X-ray inspection lens used in this invention is used to emit X-rays onto the aggregate to be inspected and simultaneously collect the generated fluorescence spectrum. The detection results are obtained by analyzing the fluorescence spectrum. Since X-ray inspection technology can be used to perform chemical composition analysis, this invention uses an X-ray inspection lens to obtain the data required for chemical composition analysis.
[0009] Furthermore, it also includes a polyester film covering mechanism for covering the upper surface of the aggregate sample to be tested with a polyester film after the aggregate sample to be tested is placed in the test hopper.
[0010] To effectively protect the inspection lens and reduce interference from other elements during inspection, this invention employs a polyester film covering mechanism. The upper surface of the polyester film covers the inspection lens tightly against the polyester film during use, protecting it when the lens emits X-rays onto the aggregate to be inspected.
[0011] Furthermore, the transmission mechanism, the detection box, the leveling roller, the detection lens, and the polyester film covering mechanism are arranged inside the metal material detection constant temperature chamber. The vacuum feeding tube is arranged through the upper surface of the metal material detection constant temperature chamber so that the outlet end of the vacuum feeding tube leads to the top of the detection box.
[0012] To ensure the accuracy of experimental data and resist external environmental interference, the testing system is set up inside a constant temperature chamber for testing metal materials.
[0013] Furthermore, the outer shell of the metal material testing constant temperature chamber is a metal shell.
[0014] This invention takes into account that although X-ray detection technology can achieve chemical composition analysis, protective equipment is required during the detection process. Therefore, this invention is specially equipped with a metal shell and a metal detection constant temperature chamber, which can further enhance the X-ray shielding performance.
[0015] Furthermore, a fully enclosed box structure is provided around the X-ray inspection lens, which separates the X-ray inspection lens and the polyester film covering mechanism from other components inside the metal inspection temperature control chamber.
[0016] To further ensure the stable operation of the X-ray inspection lens, this invention separates the X-ray inspection lens and the polyester film covering mechanism from other components inside the metal inspection constant temperature chamber, thus preventing other equipment from affecting the operational stability of the X-ray inspection lens during operation.
[0017] Furthermore, the metal material testing constant temperature chamber has a built-in temperature and humidity monitoring module.
[0018] Furthermore, the metal material testing constant temperature chamber has a built-in temperature control unit.
[0019] Furthermore, the metal material testing constant temperature chamber has a built-in dehumidifying fan.
[0020] To ensure the accuracy of experimental data and resist external environmental interference, this device is equipped with a high-precision temperature and humidity monitoring module, a temperature control unit (i.e., a heating / cooling unit), and a dehumidifying fan. This allows the temperature and humidity monitoring module to monitor the conditions inside the chamber and control the operation of the temperature control unit and dehumidifying fan based on specific conditions, ensuring that the temperature and humidity inside the chamber remain stable within the preset threshold range, thereby guaranteeing the stability of the testing process and the accuracy of the results.
[0021] Furthermore, the testing box is connected to a weighing sensor for weighing the mechanical aggregate sample to be tested inside the testing box.
[0022] This invention uses a weighing sensor to obtain the weight of the aggregate to be tested in the testing box, and then uses the weight information to stop feeding or transport the aggregate for inspection.
[0023] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

[0030] Example of a chemical composition detection device for machine-made aggregates
[0031] like Figure 1 and Figure 2 As shown, the chemical composition detection device for machine-made aggregates in this embodiment includes a vacuum extractor 1, a vacuum feeding pipe 2, a transmission mechanism 4, a detection material box 3 disposed on the transmission mechanism, a leveling pressure roller 5 disposed above one end of the transmission mechanism 4, and a detection lens disposed above the other end of the transmission mechanism 4. One end of the vacuum extractor 1 is connected to a storage device for the machine-made aggregate sample to be tested, and the other end is connected to the vacuum feeding pipe 2. The other end of the vacuum feeding pipe 2 leads to the top of the detection material box. The device also includes a polyester film covering mechanism 7 for covering the surface of the machine-made aggregate sample to be tested with a polyester film after the sample is placed in the detection material box. Figure 1 As shown, to ensure the accuracy of experimental data and resist external environmental interference, a metal material detection constant temperature chamber 9 is set in this device, and the transmission mechanism, detection material box, leveling pressure roller, detection lens and polyester film covering mechanism are set inside the metal material detection constant temperature chamber. The vacuum feeding tube 2 is set through the upper surface of the metal material detection constant temperature chamber so that the outlet end of the vacuum feeding tube leads to the top of the detection material box.
[0032] In this embodiment, an X-ray inspection lens 6 is used for detection. To ensure safety during the detection process, the device in this embodiment requires protective equipment. Therefore, the constant temperature chamber in this embodiment is a metal inspection constant temperature chamber 9, with a metal outer shell 10. A fully enclosed chamber structure 8 is set around the X-ray inspection lens 6 to separate the X-ray inspection lens 6 and the polyester film covering mechanism from other components inside the metal inspection constant temperature chamber. Furthermore, to ensure the accuracy of experimental data and resist external environmental interference, this device incorporates a temperature and humidity monitoring module 11, a temperature control unit 12, and a dehumidifying fan 13. To obtain the weight of the aggregate to be tested in the test hopper, a weighing sensor 14 is installed on the test hopper. This weighing sensor 14 is used to weigh the aggregate sample in the test hopper, thereby enabling subsequent stopping of feeding or transportation for inspection based on the weight information. Figure 1 as well as Figure 2As shown, to ensure the stable operation of the X-ray inspection lens, a fully enclosed enclosure structure 8 is set around the X-ray inspection lens. This ensures the stability of the environment in which the X-ray inspection lens is located. Furthermore, this embodiment considers that although a metal temperature-controlled chamber 9 is provided, the use of the X-ray inspection lens requires obtaining information about the sample in the inspection cassette 3 below the X-ray inspection lens. Therefore, an opening needs to be made on the lower part of the metal temperature-controlled chamber 9 at the location of the area to be inspected. However, this opening reduces the effectiveness of the metal temperature-controlled chamber 9. Therefore, to further ensure the stability of the X-ray inspection lens during operation, this embodiment... In this example, the temperature and humidity monitoring module 11 is placed outside the fully enclosed enclosure structure 8, while the temperature control unit 12 and dehumidifying fan 13 are placed inside the fully enclosed enclosure structure 8. This arrangement allows the temperature control unit 12 and dehumidifying fan 13 to specifically target the space where the X-ray inspection lens is located. That is, when the temperature and humidity monitoring module 11 detects that the temperature (or humidity) does not meet the requirements, the temperature control unit 12 (or dehumidifying fan 13) starts working to ensure that the X-ray inspection process of the lens can be carried out under optimal environmental conditions, unaffected by changes in the external environment, thus ensuring the accuracy of the X-ray inspection. Specifically, as follows... Figure 1 as well as Figure 3 As shown in this embodiment, the temperature control unit 12 is fixed to the inner wall of the fully enclosed box structure 8, as follows: Figure 2 As shown in this embodiment, the dehumidifying fan 13 is installed on the top of the fully enclosed cabinet structure 8.
[0033] The transmission mechanism 4 in this embodiment is designed to allow the detection cartridge to move between the sample acquisition area and the area to be detected, and to stop in both areas. This enables the detection cartridge to stop in the sample acquisition area to acquire samples, and after sample acquisition, to transport the detection cartridge to the area to be detected and stop there for sample detection. This embodiment provides a specific configuration of the transmission mechanism 4, such as... Figure 1 and Figure 2As shown, the transmission mechanism 4 includes two parallel structures with a hollow center, each containing a slide rail. A rod-shaped structure with rollers at both ends that match the slide rails is also included. By placing the rollers on the two parallel slide rails, the rod-shaped structure can move along them. Since the ends of the two parallel structures are not hollow, the rod-shaped structure is limited to moving only in the hollow section with the slide rails, thus preventing it from stopping at either end. Based on this transmission mechanism 4 provided in this embodiment, the bottom of the detection box 3 is fixed to the rod-shaped structure, allowing the detection box 3 to move with the rod-shaped structure. This enables the detection box to move between the sample acquisition area and the detection area, and to stop in both areas. Alternatively, a conveyor belt can be used as the transmission mechanism, placing the detection box on it so that it moves with the belt, which also meets the requirements of this embodiment.
[0034] like Figure 1 as well as Figure 3 As shown, in this embodiment, the leveling roller is set in the sample acquisition area. By setting a frame structure higher than the plane where the top surface of the test box is located, the leveling roller 5 is set on the frame structure so that the leveling roller 5 is set above the test box. In this embodiment, the leveling roller 5 is required to compact and flatten the sample in the test box 3, and it does not affect the acquisition process of the test box when the test box acquires the sample. Therefore, in this embodiment, the leveling roller is stopped near the metal material test constant temperature chamber when not in operation, so as not to affect the process of the test box acquiring the sample.
[0035] like Figure 2 As shown, the polyester film covering mechanism 7 of this embodiment includes two limiting rods, two fixing rods, and a polyester film disposed on one of the fixing rods. The other fixing rod fixes the end of the polyester film. The two limiting rods are used to fix the position of the polyester film in the middle part of the two fixing rods, as shown. Figure 2As shown, the bottom of the X-ray inspection lens 6 has limiting rods on both sides. The polyester film passes under these limiting rods and is fixed to another fixing rod, thus forming a polyester film protective layer between the X-ray inspection lens 6 and the top of the sample container in the area to be inspected, protecting the X-ray inspection lens 6. Furthermore, by making the fixing rods rollable, the used polyester film can be wrapped around it, allowing for the renewal of the polyester film below the X-ray inspection lens 6. This embodiment also considers the impact of different sample information acquisition positions of the X-ray inspection lens 6 on the accuracy of the detection results. Therefore, the X-ray inspection lens 6 can be fixed inside the metal detection temperature chamber 9, allowing it to move back and forth and left and right. This allows the X-ray inspection lens 6 to be moved to a designated position during the inspection process to acquire information from multiple detection points, thereby improving the accuracy of the final detection results. Specifically, the X-ray inspection lens 6 can be fixed inside the metal detection temperature chamber 9 by using a panel with slide rails, or by other existing methods.
[0036] The element detection range of conventional X-ray detectors on the market is significantly limited. They can usually only perform basic detection on a few common chemical elements, such as SiO2 (silicon dioxide), Fe2O3 (ferric oxide), Al2O3 (aluminum oxide), CaO (calcium oxide), and MgO (magnesium oxide), which is difficult to meet the comprehensive detection needs in complex scenarios.
[0037] Our X-ray detection technology, with its two core technological advantages of high-precision fluorescence collector identification and ultra-low temperature vacuum detection environment, has achieved a qualitative breakthrough in detection capabilities: it can cover all elements in the periodic table from sodium (Na) to uranium (U), whether they are metallic, non-metallic, or rare elements with low content, and can accurately detect them, greatly expanding the application scenarios of detection and providing more comprehensive data support for material composition analysis, quality control, and other purposes.
[0038] The chemical composition detection device for mechanical aggregates in this embodiment can achieve the following process:
[0039] After the aggregate to be tested is fed into the testing bin of the online monitoring system for the chemical composition of machine-made aggregates, the weighing sensor inside the bin starts working. When the system detects that the aggregate to be tested exceeds the entire testing bin, it stops vacuum feeding based on the weight of the aggregate and automatically starts the leveling roller. The leveling roller operates to remove excess aggregate from the testing bin and compacts and flattens the aggregate to be tested inside, preparing it for subsequent testing.
[0040] After the aggregate box to be inspected is conveyed to the inspection position, a polyester film is used to cover the upper surface of the material to effectively protect the inspection lens and reduce interference from other elements. The inspection lens is then tightly attached to the polyester film, emitting X-rays onto the aggregate and simultaneously collecting the resulting fluorescence spectrum. Finally, the inspection results are obtained by analyzing the fluorescence spectrum. While conventional X-ray inspection technology can perform chemical composition analysis, protective equipment is required during the process. This equipment is specially equipped with a metal shell and a metal-material constant temperature chamber to further enhance X-ray shielding performance, with a maximum annual radiation dose of less than 2 mSv, far below the international safety threshold. To ensure the accuracy of the inspection results, multi-point inspection technology is used. The equipment controls the movement of the inspection lens, selects four inspection areas, and averages the values to obtain the final inspection result.
[0041] To ensure the accuracy of experimental data and resist external environmental interference, the testing system adopts a fully enclosed chamber structure, with built-in high-precision temperature and humidity monitoring modules, heating / cooling units (i.e., temperature control units), and dehumidifying fans. A closed-loop control system collects environmental parameters in real time and dynamically adjusts the operating status of the heating / cooling units and dehumidifying fans to keep the temperature and humidity inside the chamber stable within the preset threshold range, thereby ensuring the stability of the testing process and the accuracy of the results.
[0042] This invention has the following advantages: By combining a vacuum extractor with a vacuum feeding pipe, with the other end of the vacuum feeding pipe connected to the testing container, during use, only the other end of the vacuum extractor needs to be connected to the device capable of acquiring the aggregate sample to be tested. The vacuum extractor then extracts the aggregate sample stored in the original device into the vacuum feeding pipe of this invention, which then transports the sample to the testing container through the same pipe. Therefore, this invention solves the problem of inconvenient transportation caused by the need for manual placement of the sample in the prior art. Furthermore, this invention also includes a transfer mechanism that moves the testing container between the sample acquisition end and the testing end, eliminating the need for manual placement of the testing container after sample acquisition, making the testing process more convenient. The device of this invention includes a detection lens, which is used to acquire information about the sample to be tested, so as to obtain the chemical composition test results of the machined aggregate based on the acquired information. Compared with chemical analysis and colorimetric methods, the device of this invention can automatically acquire the required information (the information acquired by the detection lens to obtain the chemical composition test results of the machined aggregate), and improves the convenience and stability of the overall conveying process.
[0043] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
