Description

Technical Field

[0001] This utility model relates to the technical field of cement production and testing equipment, and in particular to a cement sample homogenization device with automatic reduction function. Background Technology

[0002] In cement production and quality testing, sample homogenization is a crucial step in ensuring the accuracy and reliability of test results. Traditional cement sample homogenization equipment typically employs manual operation or simple mechanical stirring to achieve uniform mixing. However, these devices have several shortcomings in practical applications. First, manual operation is not only inefficient but also prone to incomplete homogenization due to human error, affecting the accuracy of subsequent tests. Second, existing mechanical homogenization equipment is mostly single-function, only capable of mixing samples and unable to simultaneously perform automatic sample reduction, resulting in cumbersome sample processing procedures and increased workload and time costs for operators. Furthermore, existing equipment often struggles to guarantee consistent homogenization results when processing large batches of samples, especially when sample particle size distribution is uneven or moisture content varies significantly, making homogenization even more difficult to control. Therefore, developing a cement sample homogenization device with automatic reduction capabilities, capable of simultaneously achieving efficient homogenization and precise reduction, is of great significance for improving cement sample processing efficiency, reducing manual intervention, and enhancing the accuracy and consistency of test results. Utility Model Content

[0003] The purpose of this utility model is to provide a cement sample homogenization device with automatic reduction function, which solves the problems mentioned in the background art.

[0004] This invention is implemented as follows: a cement sample homogenization device with automatic sample reduction function. The device mainly consists of a homogenization cylinder, a stirring mechanism inside the homogenization cylinder, and a sample reduction mechanism at the bottom of the cylinder. The homogenization cylinder is the main structure, and both the stirring mechanism and the sample reduction mechanism are mounted on it. The stirring mechanism is movably connected to the homogenization cylinder via a rotating shaft. The rotating shaft drives the stirring blades to rotate within the homogenization cylinder, achieving uniform mixing of the sample. One end of the rotating shaft is equipped with a drive motor, which is connected to the rotating shaft via gears, ensuring stable operation of the rotating shaft through gear transmission. The inner wall of the homogenization cylinder has spiral guide grooves, which, in conjunction with the stirring blades, create a spiral flow of the sample within the homogenization cylinder, improving the homogenization effect. The sample reduction mechanism includes a sample reduction tube, a sample distribution plate on the sample reduction tube, and a collection box at the bottom of the sample reduction tube. The sample distribution plate distributes the sample evenly into the collection box through its sample distribution holes, achieving the automatic sample reduction function. The sample distribution plate is driven by a stepper motor and can adjust the position of the sample distribution holes according to set parameters to ensure consistent reduction ratios each time. A guide plate with an inclined shape is installed at the inlet of the reduction tube to guide the sample evenly into the sample distribution plate and prevent sample accumulation. Multiple collection boxes are provided, each corresponding to one sample distribution hole, facilitating the classified collection of samples.

[0011] A specific embodiment of the cement sample homogenization device with automatic fraction reduction function of this utility model is described in conjunction with the appendix. Figure 1 To be continued Figure 3 Please provide a detailed explanation. For example... Figure 1 As shown, the equipment mainly consists of a homogenization cylinder 1, a stirring mechanism 2, and a reducing mechanism 8. The homogenization cylinder 1 serves as the main structure, the stirring mechanism 2 is movably connected to the homogenization cylinder 1 via a rotating shaft 3, and the reducing mechanism 8 is located at the bottom of the homogenization cylinder 1 and works in conjunction with the stirring mechanism 2. The overall design of the equipment aims to achieve efficient homogenization and automatic reducing of cement samples, reducing manual intervention and improving testing accuracy and efficiency.

[0012] In the specific implementation process, the cement sample to be processed is first fed into the feed inlet at the top of the homogenization cylinder 1. To ensure that the sample is evenly distributed within the homogenization cylinder 1, the inner wall of the homogenization cylinder 1 is provided with spiral guide grooves 7, such as... Figure 2 As shown. The spiral guide channel 7 is designed to guide the sample to form a spiral flow during stirring, thereby avoiding uneven mixing caused by sample accumulation or local concentration. The core components of the stirring mechanism 2 are the rotating shaft 3 and the stirring blades 4. One end of the rotating shaft 3 is connected to the drive motor 5 through the gear 6, and the drive motor 5 drives the rotating shaft 3 to operate stably through the gear transmission system. The stirring blades 4 are fixed on the rotating shaft 3, and their shape and angle are optimized to apply appropriate shear force and pushing force to the sample during rotation, so that the sample forms a multi-directional motion trajectory inside the homogenization cylinder 1, further improving the homogenization effect.

[0013] When the drive motor 5 starts, the rotating shaft 3 drives the stirring blades 4 to rotate at a set speed. The sample is fully mixed under the combined action of the spiral guide channel 7 and the stirring blades 4. The design of the spiral guide channel 7 not only helps to achieve uniform distribution of the sample, but also extends the residence time of the sample in the homogenization cylinder 1, thereby improving the homogenization efficiency. In addition, the rotation speed and direction of the stirring blades 4 can be adjusted according to actual needs, and the homogenization treatment of cement samples with different viscosities and particle sizes can be achieved by controlling the operating parameters of the drive motor 5.

[0014] After the homogenization process is completed, the sample enters the reduction mechanism 8 through the outlet at the bottom of the homogenization cylinder 1. For example... Figure 2 and Figure 3 As shown, the sample reduction mechanism 8 includes a reduction tube 9, a sample distribution tray 10, and a collection box 11. The sample distribution tray 10 is located inside the reduction tube 9 and is precisely rotated by a stepper motor 13. The sample distribution tray 10 has multiple sample distribution holes 12, each corresponding to a collection box 11, ensuring that the sample can be distributed to different collection boxes 11 according to a preset ratio. The rotation angle and position of the sample distribution tray 10 are precisely adjusted by the stepper motor 13 according to set parameters, thereby achieving consistency and accuracy in each reduction operation.

[0015] To ensure that the sample enters the dispensing tray 10 uniformly, an inclined guide plate 14 is provided at the inlet of the reducing tube 9. The function of the guide plate 14 is to guide the sample to slide down the inclined surface, preventing the sample from accumulating or clogging at the inlet, while ensuring that the sample enters the dispensing tray 10 at a uniform flow rate. Driven by the stepper motor 13, the dispensing tray 10 rotates at a set angle. After each rotation, the position of the dispensing hole 12 changes, allowing the sample to flow sequentially into different collection boxes 11. The rotation speed and angle of the dispensing tray 10 can be adjusted by the control system to adapt to the reduction requirements of different batches of samples.

[0016] The number and capacity of the collection boxes 11 are designed according to the actual application scenario, and are usually set to multiple boxes to collect samples of different proportions. For example, in some testing scenarios, it may be necessary to divide the sample into three parts for chemical composition analysis, physical performance testing, and backup storage, respectively. In this case, the number and position of the sampling holes 12 on the sampling plate 10 can be preset to three equal parts, and the stepper motor 13 controls the rotation of the sampling plate 10 according to the set program to ensure that the proportion of each sample is consistent and the distribution is uniform.

[0017] The operation process of the equipment is as follows: First, the cement sample to be processed is put into the homogenization cylinder 1, and the drive motor 5 is started to start the stirring mechanism 2. The stirring blades 4, driven by the rotating shaft 3, thoroughly mix the sample, and the spiral guide groove 7 assists in forming a spiral flow of the sample to ensure the best homogenization effect. Subsequently, the homogenized sample enters the reducing mechanism 8 through the discharge port at the bottom of the homogenization cylinder 1. In the reducing mechanism 8, the sample is guided evenly into the sample distribution plate 10 by the guide plate 14. The sample distribution plate 10 rotates according to the set parameters under the drive of the stepper motor 13, and the sample is distributed to the corresponding collection box 11 through the sample distribution hole 12. The entire process requires no manual intervention, and all operations are automatically completed by the control system, thereby significantly improving the sample processing efficiency and detection accuracy.

[0018] Furthermore, all components of the equipment are made of corrosion-resistant and wear-resistant materials to accommodate the special properties of cement samples. For example, the inner wall of the homogenization cylinder 1 and the surface of the stirring blades 4 are specially treated to provide excellent wear resistance, effectively extending the service life of the equipment. The sample distribution plate 10 and the collection box 11 are made of easy-to-clean materials, allowing for thorough cleaning after each use and preventing sample residue from affecting subsequent test results.

[0019] In summary, this utility model provides a cement sample homogenization device with automatic reduction function, which achieves efficient homogenization and automatic reduction of cement samples through the coordinated operation of the homogenization cylinder 1, the stirring mechanism 2, and the reduction mechanism 8. The operating principle and process of the device are clear and well-defined, and the functional design of each component is reasonable, which can meet the needs of large-scale sample processing, while significantly improving the reliability and accuracy of the test results.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
