Description

Technical Field

[0001] This utility model relates to the field of intelligent sampling and preparation equipment technology, specifically to a sample retention device for an intelligent sampling and preparation system. Background Technology

[0002] In daily work, in order to ensure that the measured parameters are not biased due to the sampling and sample preparation process, the laboratory often uses the raw coal comparison method to confirm the representativeness and uniformity of the sample. Although the intelligent sampling and preparation equipment will retain 13mm and 3mm samples for reference during the sample preparation process.

[0003] However, in the use of intelligent sampling and preparation equipment, the equipment does not have the function of retaining raw coal samples, which makes it impossible to conduct comparative tests of raw coal samples after sampling and before sample preparation. It is difficult to accurately judge the stability of the equipment and the representativeness of the samples. Once the sampling and preparation equipment deviates, even if the coal sample deviation is large, it is difficult to detect visually and it is not easy for the laboratory to detect the abnormality of the equipment in time. This leads to inaccurate test results, which greatly increases the quality control risk of incoming coal, causes disputes, and even brings serious economic losses.

[0004] In summary, the problems with the current use of intelligent sampling and preparation equipment are:

[0005] (1) There is a problem that the samples are not retained;

[0006] (2) It is impossible to compare the quantity and quality of the retained samples and the discarded samples after sampling, so as to discover the problem of the sample mixing machine in time.

[0007] (3) Only applicable to test comparisons after automatic sample preparation and reduction. Utility Model Content

[0008] This utility model provides a sample retention device for an intelligent sampling and preparation system. By using a cleaning scraper, the coal on the conveyor mechanism can be completely scraped off, preventing coal residue on the conveyor belt and affecting accuracy. At the same time, in conjunction with the shaking discharge mechanism, the sampled coal can be completely discharged, ensuring the effectiveness of use. Adjusting the forward transmission function of the discarded sample conveyor belt to reverse allows for the rapid and accurate return of the discarded sample after the batch of coal samples has been retained. This solves the system program problem of not being able to retain 13mm samples for future reference. Furthermore, it can be used not only for monitoring intelligent equipment but also for laboratory review and comparison. It is simple, convenient, and effective in use, effectively solving the defect of not having raw coal samples for review before sample preparation caused by technical problems in the intelligent sampling and preparation process. It can be widely applied to intelligent sampling and preparation system devices.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a sample retention device for an intelligent sampling and preparation system, comprising:

[0031] Protective cover 1;

[0032] The transmission mechanism is located inside the protective cover 1;

[0033] The flow guiding mechanism is located inside the protective cover 1;

[0034] The cleaning scraper 7 is fixedly connected inside the protective cover 1 and is connected to the transmission mechanism.

[0035] A swaying discharge mechanism is located inside the protective cover 1. The swaying discharge mechanism includes a control component, a movable port 14, and a guide pipe 10. The movable port 14 is located on one side of the bottom of the protective cover 1 near the edge. The control component is located on one side of the bottom of the protective cover 1 near the edge. One end of the guide pipe 10 is installed inside the movable port 14, and the guide pipe 10 is mounted on the control component.

[0036] The sealing mechanism is located on the protective cover 1.

[0037] In this implementation plan: The entire device is installed on the sampling equipment and controlled by a frequency converter. The motor's running direction is automatically switched via a switch signal. When the received signal is reversed, the motor runs in reverse. The frequency converter operates within the sampling equipment's internal control mode. By setting parameters such as the frequency converter's operating frequency and voltage, the motor's running direction is switched, causing it to run in reverse. This is an application of existing technology and will not be elaborated further. A protective cover 1 is installed at the end of the waste material conveying pipeline of the waste sample equipment, forming a standard coal outlet. The protective cover 1 prevents sample contamination and ensures environmental hygiene. The cleaning scraper 7 cleans the conveying mechanism... After the coal is cleaned and used, the guide pipe 10 sways left and right within the movable port 14 to ensure rapid and residue-free discharge of the coal. A storage bucket is placed at the bottom of the guide pipe 10 for storage. After storage, the weight is checked first. The total sample volume equals the sum of the prepared sample volume and the discarded sample volume, which is within the normal range. The sample is then stored in the storage room for future reference. If the difference is inconsistent, it may be a problem with the sample combining machine. This helps to promptly identify the root cause of the problem, resolve the fault point, and adopt other sample preparation methods to ensure the representativeness and uniformity of the sample. Regularly comparing the reserve sample with the intelligent sample can effectively monitor whether the results of the intelligent sample preparation system are accurate, thus achieving effective quality control of people, machines, and environment.

[0038] Specifically, the transmission mechanism includes a transmission roller shaft 5 and a transmission belt 4. The transmission roller shaft 5 is rotatably connected inside the protective cover 1, and the transmission belt 4 is sleeved on the transmission roller shaft 5.

[0039] In this embodiment, the transmission roller 5 controls the rotation of the transmission belt 4 to complete the transmission. This is an application of existing technology and will not be elaborated on here. The transmission belt 4 is controlled by a motor to work in reverse.

[0040] Specifically, the flow guiding mechanism includes a clamping plate 2 and a flow guiding bucket 13. There are two clamping plates 2, both of which are movably connected inside the protective cover 1. The two clamping plates 2 are respectively located on both sides of the conveyor belt 4. The flow guiding bucket 13 is fixedly connected inside the protective cover 1 near one edge.

[0041] In this embodiment: the clamping plate 2 can adapt to different widths of the conveyor belt 4 to ensure its use, and the guide bucket 13 can make the coal flow accurately into the guide pipe 10.

[0042] Specifically, the control components include a movable cylinder 9 and a movable plate 8. A movable cavity 6 is provided between the guide bucket 13 and the movable port 14. The movable plate 8 is movably connected in the movable cavity 6. There are two movable cylinders 9. The two movable cylinders 9 are respectively fixedly connected to one edge of the bottom of the protective cover 1, and the output ends of the two movable cylinders 9 are respectively fixedly connected to both sides of the movable plate 8.

[0043] In this embodiment, the model of the movable cylinder 9 can be selected from those available on the market as needed, which will not be elaborated here. The movable plate 8 is controlled to move left and right in the moving cavity 6 by the movable cylinder 9 to complete the rapid material discharge.

[0044] Specifically, the sealing mechanism includes a positioning plate 3 and a sealing plate 12. The positioning plate 3 is fixedly connected to one end of the protective cover 1, and the sealing plate 12 is fixedly connected to the positioning plate 3 by bolts.

[0045] In this embodiment, the positioning plate 3 and the sealing plate 12 cooperate with each other to ensure the sealing of the end of the protective cover 1.

[0046] Specifically, the outer surface of the sealing plate 12 is fixedly connected to two handles 11.

[0047] In this embodiment, the two handles 11 facilitate opening the sealing plate 12 for use.

[0048] In use, the protective cover 1 is installed at the end of the sampling equipment. The conveyor belt 4 is reversed by the motor, so that the conveyor belt transports the waste coal sample in the opposite direction. The sample flows to the end of the waste pipe through the conveyor belt and falls into the guide pipe 10 through the guide bucket 13 for discharge. After discharge, the cleaning scraper 7 cleans the coal on the conveyor belt 4 to ensure accurate values. At the same time, the movable cylinder 9 controls the movable plate 8 to drive the guide pipe 10 to swing left and right to complete the rapid discharge. The sample falls into the storage bucket at the bottom for sample retention. After the coal sample is collected, the sampling personnel tighten the bucket lid, attach the sealing strip with sample information, and weigh and record it.

[0049] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
