Description

Technical Field

[0001] This invention relates to the field of cement testing technology, and in particular to a cement testing process. Background Technology

[0002] Cement testing refers to the process of inspecting and evaluating the quality of cement. Cement is a commonly used building material, and testing its quality ensures the safety and stability of construction projects.

[0003] Current detection devices can simultaneously detect multiple elements in cement. For example, Chinese Patent Publication No. CN202256203U discloses a "neutron cement multi-element rapid analyzer" capable of rapidly and accurately analyzing the silicon, aluminum, iron, calcium, and magnesium content in cement. The cement tank is placed between the DD neutron tube and the gamma-ray detector (BGO), all three being cylindrical with their axes aligned.

[0004] Currently, to facilitate cement testing, some testing devices are directly installed on the conveyor line. However, due to the varying speeds of the conveyor lines, the testing instrument is unable to accurately analyze the elements in the cement. Therefore, to improve the cement testing effect, we propose a cement testing process. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a cement testing process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a cement testing process, including the following steps:

[0008] S1. Fix the machine above the cement conveying line;

[0009] S2. Cement is uniformly conveyed to the bottom of the detector via the lifting device and conveyor line inside the machine. The detector inside the machine is used to analyze and test the cement. The detector is located at the top of the machine and below the lifting device.

[0010] S3. During the lifting process, the cement accumulated in front of the lifting device is discharged to the rear of the conveyor line through the side discharge device to avoid accumulation.

[0011] S4. The cement that has been tested continues to be conveyed forward by the lifting device, and then falls back onto the conveyor belt after passing through the guide plate for transfer.

[0012] Furthermore, the lifting device is a Z-shaped lifting mechanism, and a guide plate is also installed at the feed end of the Z-shaped lifting mechanism. The Z-shaped lifting mechanism is installed on the inner side of the machine tool by a bracket.

[0013] Furthermore, the side discharge device includes two rollers installed on both sides of the lifting device, and a scraper belt is sleeved between the two rollers. A motor is also installed on the side end of one of the rollers, and the motor is fixed to the lifting device.

[0014] Furthermore, a speed regulating mechanism is also installed on the side of the lifting device, which is used to adjust the speed of the motor.

[0015] Furthermore, the speed regulating mechanism includes a top rod slidably connected to one side of the lifting device, a spring connecting the top rod and the lifting device, and a baffle installed on the side end of the top rod.

[0016] Furthermore, the top rod has an L-shaped structure, and a screw and a guide rod are also installed above the baffle. The screw is threadedly connected to the top rod, and the guide rod is inserted into the top rod.

[0017] Furthermore, a fixed base is installed on one side of the lifting device, and a speed control switch is installed on the fixed base, which abuts against the free end of the top rod.

[0018] Furthermore, the guide plate is fixed to one side of the lifting device by a bracket.

[0019] Furthermore, a brush plate is installed at the tail end of the guide plate, and the brush plate abuts against the conveyor belt of the lifting device.

[0020] Furthermore, the guide plate and the brush plate are connected by a spring telescopic rod.

[0021] The cement testing process proposed in this invention has the following advantages: By installing a lifting device inside the machine, the cement on the conveyor line is conveyed upwards at a uniform speed and moved below the testing instrument. Compared to direct testing by the instrument, this uniform speed design further improves the accuracy of cement testing and analysis, avoiding the influence of the conveyor line speed. Furthermore, a side-discharge device is also included to prevent cement accumulation on the conveyor line due to the lifting device design. The overall structural design is reasonable, ensuring the effectiveness of cement testing and analysis. Attached Figure Description

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figure 1-6 This invention discloses a cement testing process, which includes the following steps:

[0031] S1. Fix the machine 1 above the cement conveying line;

[0032] S2. Cement is uniformly conveyed to the bottom of the detector 4 through the lifting device 2 inside the machine 1 and the detector 4 inside the machine 1 is used to analyze and test the cement. The detector 4 is located at the top inner part of the machine 1 and below the lifting device 2.

[0033] S3. During the lifting process of the lifting device 2, the cement accumulated in front of the lifting device 2 is discharged to the rear of the conveyor line through the side discharge device 5 to avoid accumulation.

[0034] S4. The cement that has been tested continues to be conveyed forward by the lifting device 2, and then falls back onto the conveyor belt after passing through the guide plate 6 for transfer.

[0035] In other words, the lifting device 2 used in this invention is used to lift the cement on the conveyor line at a uniform speed, so that the detector 4 can accurately analyze and detect the cement composition. The independent conveying design is not affected by the speed of the conveyor line, ensuring the accuracy of the detection. At the same time, the side discharge device 5 can quickly discharge the cement accumulated in front of the lifting device 2 to the rear, so that the cement can accumulate in front.

[0036] In some embodiments, the lifting device 2 described in this invention is a Z-shaped lifting mechanism. The Z-shaped lifting mechanism is existing technology and will not be described in detail here. A guide plate 21 is also installed at the feed end of the Z-shaped lifting mechanism. The guide plate 21 is used to promote the cement on the conveyor line to move onto the lifting device 2. The Z-shaped lifting mechanism is installed on the inner side of the machine base 1 through the bracket 22. Preferably, in this embodiment, the Z-shaped lifting mechanism is installed in the middle of the machine base 1 to ensure that when the machine base 1 is installed on the conveyor line, the guide plate 21 can guide the cement in the middle of the conveyor line.

[0037] Based on the above embodiments, the side discharge device 5 of the present invention includes two rollers 51 installed on both sides of the lifting device 2, and a scraper belt 52 is sleeved between the two rollers 51. The scraper belt 52 is composed of a conveyor belt and scraper strips installed on the conveyor belt. It should be noted that the scraper belt 52 is a certain distance away from the upper surface of the conveyor belt of the conveyor line to avoid interference between the two movements. A motor 53 is also installed on the side end of one of the rollers 51, and the motor 53 is fixed to the lifting device 2.

[0038] In other words, when the lifting device 2 is lifting cement, if the speed of the conveyor line is greater than the lifting speed of the lifting device 2, cement will accumulate in front of the lifting device 2 and be squeezed to both sides. At this time, the motor 53 drives the roller 51 to rotate, and the scraper belt 52 rotates to scrape and convey the cement in front, so as to avoid the phenomenon of cement accumulation and ensure that the lifting device 2 can work normally.

[0039] Furthermore, the lifting device 2 described in this invention is also equipped with a speed regulating mechanism 7 on its side, which is used to regulate the speed of the motor 53.

[0040] For example, in this invention, the speed regulating mechanism 7 includes a top rod 71 slidably connected to one side of the lifting device 2, and a spring 72 is also connected between the top rod 71 and the lifting device 2. A baffle 73 is also installed on the side end of the top rod 71.

[0041] Furthermore, the top rod 71 has an L-shaped structure, and a screw 74 and a guide rod 75 are installed above the baffle 73. The screw 74 is rotatably connected to the baffle 73, and the screw 74 is threadedly connected to the top rod 71. The guide rod 75 is inserted into the top rod 71. That is, in this embodiment, the user can adjust the height of the entire baffle 73 by rotating the screw 74 to adjust it according to the actual cement accumulation. For example, when the baffle 73 is adjusted downward, the baffle 73 can be pushed to move when the cement accumulates to a certain height. This controls the intervention of the speed adjustment mechanism 7 to complete the control of the sensitivity of the speed adjustment mechanism 7.

[0042] Furthermore, in this invention, a fixed base 76 is installed on one side of the lifting device 2, and a speed control switch 77 is installed on the fixed base 76. The speed control switch 77 abuts against the free end of the top rod 71. That is, when cement accumulates, it will push the top rod 71 to move, and one end of the top rod 71 will abut against the speed control switch 77. As the amount of cement accumulated increases, the thrust increases, and the depth of the top rod 71 abutting against the speed control switch 77 also increases. Therefore, the speed of the motor 53 will increase, thereby speeding up the conveying of the cement accumulated on the conveyor line and increasing the unloading speed. Similarly, when the accumulation is small, the scraper belt 52 rotates at a low speed to achieve energy saving and stably ensure the conveying stability of the conveyor line.

[0043] Furthermore, the guide plate 6 is fixed to one side of the lifting device 2 by the bracket 61.

[0044] In addition, in order to clean the tail end of the conveyor belt of the lifting device 2, a brush plate 62 is installed at the tail end of the guide plate 6 in this invention, and the brush plate 62 abuts against the conveyor belt of the lifting device 2.

[0045] Preferably, the guide plate 6 and the brush plate 62 are connected by a spring telescopic rod 63. The elastic support design of the spring telescopic rod can ensure that the brush plate and the conveyor belt of the lifting device 2 always maintain stable contact, thereby improving the cleaning effect on the lifting device 2.

[0046] In summary, by setting a lifting device 2 on the inner side of the machine 1, the present invention uses a uniform speed to convey cement upward on the conveyor line and move it to the bottom of the detector 4. Compared with the direct detection method of the detector 4, this uniform speed design can further improve the accuracy of cement detection and analysis and avoid the problem of being affected by the conveyor line speed. Secondly, the present invention also sets a side discharge device 5, which can avoid the problem of cement accumulation on the conveyor line due to the design of the lifting device 2. The overall structural design is reasonable and ensures the detection and analysis effect of cement.

[0047] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
