Description

Technical Field

[0001] The utility model relates to a device for sampling from a pipeline for detection, in particular to a pipeline sampling device which is convenient to use. Background Art

[0002] Currently, many materials are transported within pipelines. For example, ore slurry in mineral processing plants is typically transported via pipelines. Slurry transported through pipelines requires periodic sampling for testing. However, current sampling devices manually place a sampling bucket below a sampling port valve on the pipeline, open the valve, and allow the slurry in the pipeline to flow into the sampling bucket for sampling. This sampling method requires workers to reach the sampling port valve within a specified timeframe to complete sampling, which is very inconvenient. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a pipeline sampling device that is easy to use.

[0004] In order to solve the above technical problems, the technical solution proposed in the utility model is: a pipeline sampling device, including a circular turntable device, a turntable bracket and a sampling bucket, the turntable device is arranged on the turntable bracket, the sampling bucket is arranged on the circular turntable device, and at least two sampling buckets are arranged on the circular turntable device; the circular turntable device includes a plane rolling bearing, a barrel carrying circular plate and a power assembly, the barrel carrying circular plate is fixedly connected to the upper plate of the plane rolling bearing, and the barrel carrying circular plate is connected to the power assembly.

[0005] In the above-mentioned pipeline sampling device, preferably, the power assembly includes a motor, a gear and connecting teeth on the edge of the barrel-carrying circular plate; the gear is connected to the motor, and the gear is engaged with the connecting teeth.

[0006] In the above-mentioned pipeline sampling device, preferably, the outer side surface of the entire edge of the barrel-carrying circular plate is provided with connecting teeth.

[0007] In the above-mentioned pipeline sampling device, preferably, a sensing component is provided on the barrel carrying circular plate; the sensing component includes a positioning sensing block and a sensing switch, the number of the positioning sensing blocks is consistent with the number of sampling barrels, and a plurality of the positioning sensing blocks are evenly arranged on the bottom surface of the outer side of the barrel carrying circular plate and extend out of the outer edge of the barrel carrying circular plate; the sensing switch is arranged opposite to the positioning sensing block, and the sensing switch is connected to the motor of the power component through the PLC.

[0008] Compared with the existing technology, the advantages of the present invention are: in this utility model, the barrel is placed on the barrel-carrying circular plate, and the motor can rotate the sampling barrel to the bottom of the sampling port valve on the pipeline within a specified time, opening the valve to complete the sampling. In this embodiment, the barrel-carrying circular plate on the circular turntable device automatically rotates according to the preset time, and the sampling barrel rotates synchronously with the barrel-carrying disc, ensuring that the sample taken within the preset time period is accurately placed in the designated sampling barrel, avoiding sampling failure within the specified time due to human factors, and achieving sampling accuracy and sample representativeness.

[0013] In order to facilitate the understanding of the present invention, the present invention will be described in more comprehensive and detailed manner below in conjunction with the accompanying drawings and preferred embodiments of the specification, but the protection scope of the present invention is not limited to the following specific embodiments.

[0014] It should be noted that when an element is described as being "fixed, fixed, connected or communicated with" another element, it can be directly fixed, fixed, connected or communicated with the other element, or it can be indirectly fixed, fixed, connected or communicated with the other element through other intermediate connectors.

[0015] Unless otherwise defined, all technical terms used hereinafter have the same meanings as those generally understood by those skilled in the art. The technical terms used herein are only for the purpose of describing specific embodiments and are not intended to limit the scope of protection of the present invention. Example

[0016] like Figure 1 and Figure 2The illustrated pipeline sampling device 1 is disposed below the sampling port of the pipeline 1. The slurry within the pipeline 1 is mineral slurry. The pipeline sampling device 1 of this embodiment includes a circular turntable assembly 3, a turntable bracket 4, and sampling buckets 5. The turntable assembly is mounted on the turntable bracket 4, and the sampling buckets 5 are mounted on the circular turntable assembly 3. Three sampling buckets 5 are mounted on the circular turntable assembly 3. The circular turntable assembly 3 includes a planar rolling bearing 31, a bucket-carrying circular plate 32, and a power assembly 33. The bucket-carrying circular plate 32 is fixedly connected to the upper plate of the planar rolling bearing 31 and is connected to the power assembly 33. In this embodiment, the power assembly 33 includes a motor 331, a gear 333, and connecting teeth 334 on the edge of the bucket-carrying circular plate 32. The gear 333 is connected to a reducer 332, which is connected to the motor 331. The gear 333 meshes with the connecting teeth 334.

[0017] In this embodiment, motor 331 is activated at a predetermined time via a PLC control program. This allows the sampling bucket 5 above the bucket-carrying disc 32 to be rotated below the sampling port in pipeline 1. The valve at the sampling port is then opened, allowing the slurry in pipeline 1 to flow out, completing the slurry sampling. In this embodiment, the valve at the sampling port in pipeline 1 can be a conventional electronic valve 2, which is also connected to the PLC. During sampling, the electronic valve 2 opens for a predetermined period of time and then closes, ensuring consistent weight between samples.

[0018] In this embodiment, the opening or closing of the electronic valve 2 and the starting of the motor are controlled by PLC. When the electronic valve is open, the motor is stationary, that is, the circular turntable device is stopped; when the motor is started and the circular turntable device rotates, the electronic valve is closed.

[0019] In this embodiment, the outer side surfaces of the entire edge of the barrel carrying circular plate 32 are provided with connecting teeth 334, so that the barrel carrying circular plate 32 can rotate in an opposite direction, thereby using a general motor 331 without using a stepping motor, thereby reducing costs.

[0020] In this embodiment, the barrel-carrying circular plate 32 is provided with a sensing assembly 6 . This sensing assembly 6 includes positioning sensing blocks 61 and a sensing switch 62 . The number of positioning sensing blocks 61 matches the number of sampling barrels 5 , also three. The three positioning sensing blocks 61 are evenly spaced on the bottom surface of the outer side of the barrel-carrying circular plate 32 and extend beyond the outer edge of the plate 32 . The sensing switch 62 is mounted on the turntable bracket 4 , opposite the positioning sensing blocks 61 , and is connected to the motor 331 of the power assembly 33 via a PLC.

[0021] In this embodiment, the staff only needs to take the sample in the sampling barrel 5 directly from the barrel carrying circular plate 32. At the sampling time, the motor 331 will rotate the sampling barrel 5 above the barrel carrying circular plate 32 to the bottom of the sampling port for sampling.
