Description

Technical Field

[0001] This utility model relates to the field of petrochemical technology, and in particular to a sampling device for petrochemical separation and detection. Background Technology

[0002] In the complex and critical industrial field of petrochemicals, separation and testing work acts as a solid line of defense, playing an indispensable role in ensuring product quality, optimizing production processes, and guaranteeing safe production. In the entire separation and testing process, sampling is the key initial step, and its importance cannot be underestimated. The accuracy and efficiency of sampling directly affect all aspects of subsequent petrochemical production and research.

[0003] In the petrochemical field, traditional sampling methods are mostly single-sample. This single-sample method has many drawbacks in practical applications. First, in terms of the number of samples obtained in a single sampling, only one sample can be obtained each time. After that, the sample needs to be removed before the next sampling can begin. However, in the production and research process of petrochemicals, multiple samples are needed to fully and accurately reflect the characteristics of the entire system. Therefore, in order to obtain a sufficient number of samples, it is necessary to repeat the sampling operation multiple times. This process is not only cumbersome but also inefficient, greatly increasing the time and labor costs of sampling work, which is not conducive to the efficient development of petrochemical production and research. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a sampling device for petrochemical separation and detection.

[0005] This utility model is achieved using the following technical solution: a sampling device for petrochemical separation and detection, comprising a sampling pump, a motor fixedly connected to the surface of a support frame, a lead screw fixedly connected to the output end of the motor, a threaded sleeve threadedly connected to the outer surface of the lead screw, a lifting plate fixedly connected to the surface of the threaded sleeve, limit rods penetrating both sides of the lifting plate, a collection mechanism provided on the surface of the lifting plate, a support rod fixedly connected to the upper surface of the lifting plate, an mounting plate fixedly connected to the top end of the support rod, a protective shell fixedly connected to the upper surface of the mounting plate, a sampling pump disposed inside the protective shell, a sampling tube fixedly connected to the input end of the sampling pump, and a sample delivery tube fixedly connected to the output end of the sampling pump.

[0006] The above technical solution enables convenient sampling at different depths, improving sampling flexibility and making it suitable for obtaining samples at different depths in petrochemical separation and detection.

[0007] As a further improvement to the above solution, the collection mechanism includes a limiting slide groove, a sliding seat is slidably connected inside the limiting slide groove, a collection box is fixedly connected to the upper surface of the sliding seat, a partition plate is fixedly connected to the inner wall of the collection box, a motor base is fixedly connected to the lower surface of the lifting plate, a second motor is fixedly installed inside the motor base, a second lead screw is fixedly connected to the output end of the second motor, the second lead screw is threaded into the inside of the sliding seat, and a shaft seat is rotatably connected to the surface of the second lead screw.

[0008] The above technical solution allows for the collection of multiple samples at once, avoiding the inefficiency of single sampling and improving overall sampling efficiency. In petrochemical separation and detection, it enables the faster acquisition of multiple samples for analysis.

[0009] As a further improvement to the above solution, a pipe seat is fixedly connected to the surface of the sampling tube.

[0010] The above technical solutions enhance the stability of the sampling tube, reduce sampling errors that may occur due to shaking or other factors during the sampling process, and help improve the accuracy of sampling.

[0011] As a further improvement to the above solution, the pipe seat is fixedly connected to the upper surface of the lifting plate.

[0012] As a further improvement to the above solution, a circular seat is rotatably connected to the bottom end of the lead screw, and the circular seat is fixedly connected to the surface of the support frame.

[0013] As a further improvement to the above solution, the limiting rod is fixedly connected to the inner wall of the support frame.

[0014] As a further improvement to the above solution, the bearing is fixedly connected to the lower surface of the lifting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a motor to drive a lead screw to rotate. The threaded connection between the lead screw and the threaded sleeve, along with the limiting engagement between the threaded sleeve, the lifting plate, and the limiting rod, causes the lifting plate to rise and fall. This allows the sampling device to control the sampling depth, thereby obtaining samples at different depths and improving sampling accuracy. Subsequently, a motor drives a second lead screw to rotate. The threaded connection between the second lead screw and the sliding seat, along with the sliding connection between the sliding seat and the limiting groove, moves the collection box. At this point, the position of the collection box corresponding to the sample delivery tube changes, allowing for the collection of a second sample. This enables the collection of multiple samples at once, avoiding the low efficiency of single sampling and improving overall sampling efficiency. In petrochemical separation and detection, this allows for the faster acquisition of multiple samples for analysis. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] Example:

[0025] Please combine Figure 1-4This embodiment of a sampling device for petrochemical separation and detection includes a sampling pump 11, a motor 2 fixedly connected to the surface of a support frame 1, a lead screw 3 fixedly connected to the output end of the motor 2, a threaded sleeve 4 threadedly connected to the outer surface of the lead screw 3, a lifting plate 5 fixedly connected to the surface of the threaded sleeve 4, limit rods 6 penetrating both sides of the lifting plate 5, a collection mechanism 7 provided on the surface of the lifting plate 5, a support rod 8 fixedly connected to the upper surface of the lifting plate 5, a mounting plate 9 fixedly connected to the top of the support rod 8, a protective shell 10 fixedly connected to the upper surface of the mounting plate 9, and a sampling pump 11 disposed inside the protective shell 10. A sampling tube 12 is fixedly connected to the inlet end, and a sample delivery tube 13 is fixedly connected to the output end of the sampling pump 11. The motor 2 drives the lead screw 3 to rotate. Since the lead screw 3 is threadedly connected to the threaded sleeve 4, and the threaded sleeve 4 is limited by the lifting plate 5 and the limiting rod 6, the lifting plate 5 passes through the limiting rod 6 on both sides. Therefore, when the lead screw 3 rotates, the threaded sleeve 4 and the lifting plate 5 will rise and fall along the limiting rod 6. When the lifting plate 5 descends, it drives the sampling pump 11 and the sampling tube 12 on its surface to descend. At this time, the sampling pump 11 is started, and the sample is extracted through the sampling tube 12 and then enters the collection mechanism 7 through the sample delivery tube 13, thereby realizing the sampling operation at different depth positions.

[0026] The collection mechanism 7 includes a limiting slide groove 701, a sliding seat 702 is slidably connected inside the limiting slide groove 701, a collection box 703 is fixedly connected to the upper surface of the sliding seat 702, a partition plate 16 is fixedly connected to the inner wall of the collection box 703, a motor base 704 is fixedly connected to the lower surface of the lifting plate 5, a second motor 705 is fixedly installed inside the motor base 704, a second lead screw 706 is fixedly connected to the output end of the second motor 705, the second lead screw 706 is threaded to the inside of the sliding seat 702, and a shaft seat 707 is rotatably connected to the surface of the second lead screw 706. When the collection box 703 collects the first sample, the second motor 705 starts to work, driving the second lead screw 706 to rotate. Since the second lead screw 706 is threaded inside the sliding seat 702, and the sliding seat 702 is slidably connected to the limiting groove 701, and the second lead screw 706 is rotatably connected to the lower surface of the lifting plate 5 through the bearing seat 707, when the second lead screw 706 rotates, the collection box 703 will move along the limiting groove 701 through the sliding seat 702. In this way, the position of the collection box 703 corresponding to the sample delivery tube 13 changes, so that a second sample can be collected.

[0027] The sampling tube 12 is fixedly connected to a pipe seat 14, which serves to fix and support the sampling tube 12, so that the sampling tube 12 maintains a stable position during operation.

[0028] The pipe seat 14 is fixedly connected to the upper surface of the lifting plate 5.

[0029] The bottom end of the lead screw 3 is rotatably connected to a round seat 15, which is fixedly connected to the surface of the support frame 1.

[0030] The limiting rod 6 is fixedly connected to the inner wall of the support frame 1.

[0031] The bearing seat 707 is fixedly connected to the lower surface of the lifting plate 5.

[0032] The implementation principle of a sampling device for petrochemical separation and detection in this embodiment is as follows: First, the operator starts motor 2, which drives the lead screw 3 to rotate. Since the lead screw 3 is threadedly connected to the threaded sleeve 4, and the threaded sleeve 4 is limited by the lifting plate 5 and the limiting rod 6, the lifting plate 5 has the limiting rod 6 extending through both sides. Therefore, when the lead screw 3 rotates, the threaded sleeve 4 and the lifting plate 5 will rise and fall along the limiting rod 6. Depending on the required sampling depth, motor 2 is operated to lower the lifting plate 5 to a suitable height. When the lifting plate 5 reaches the target depth, the sampling pump 11 is started. The sampling pump 11 extracts the sample through the sampling tube 12. The sample enters the collection box 703 in the collection mechanism 7 through the sample delivery tube 13. Since the inner wall of the collection box 703 has a partition plate 16, the sample can be preliminarily processed. After the first sample collection is completed in the collection box 703, the motor 705 is started, which drives the lead screw 706 to rotate. Since the lead screw 706 is threaded inside the sliding seat 702 and the sliding seat 702 is slidably connected to the limiting slide groove 701, and the lead screw 706 is rotatably connected to the lower surface of the lifting plate 5 through the shaft seat 707, when the lead screw 706 rotates, the collection box 703 will move along the limiting slide groove 701 through the sliding seat 702, so that the position of the collection box 703 corresponding to the sample delivery tube 13 changes, and the second batch of samples is ready to be collected. The sampling pump 11 is started again, and the sampling pump 11 extracts the sample through the sampling tube 12. The sample enters another separated area in the collection box 703 after it has moved through the sample delivery tube 13.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
