Description

Technical Field

[0001] The utility model relates to the technical field related to closed sampling, and in particular to a pipeline closed sampler. Background Art

[0002] Closed pipeline sampling is an important sampling method. Through specially designed devices and processes, samples are collected while ensuring that the pipeline is in a completely closed state during the entire sampling process. This sampling method has many meanings. First, it can prevent external impurities and pollutants from entering the sampling system to the greatest extent, ensure the purity and authenticity of the collected samples, and enable them to accurately reflect the actual state of the substances in the pipeline. Secondly, it can effectively prevent the leakage of sampled substances, ensure the safety of sampling operations, and avoid harm to the environment and personnel. Closed pipeline sampling ensures the continuity and stability of sampling, and will not be interrupted or affected by external interference. The advantage of closed pipeline sampling plus a cleaning mechanism is that it can not only ensure accurate and reliable sampling, but also clean the pipeline in time to keep the system unobstructed, avoid residual impurities affecting subsequent sampling, improve sampling purity, and ensure that the sampling work is carried out continuously and stably, reduce failures, and improve overall efficiency and safety. Therefore, a closed pipeline sampler is particularly needed.

[0003] However, the existing pipeline closed sampler may cause blockage during use because mud and sand may exist inside after long-term use, resulting in slow sampling efficiency. In addition, the existing equipment is difficult to maintain and very inconvenient to disassemble. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By opening the solenoid valve, the sample enters the connecting tube and then into the storage bottle. The whole process ensures the airtightness of the sampling, can accurately obtain the sample and avoid external interference, and ensures the purity and accuracy of the sample. Then, use the water pump to extract the water source in the water tank to clean the connecting tube, realizing the automatic cleaning function after sampling, which not only keeps the connecting tube clean for the smooth progress of subsequent sampling, but also improves the sampling efficiency. The cleaned water source is filtered through the filter tube and then returned to the water tank for secondary use, which reflects the effective recycling of resources and reduces costs. The filter net can also be taken out and cleaned to ensure the continuity of the filtering effect. At the same time, the waste water can be discharged through the connecting tube, which increases the flexibility of use.

[0015] 2. The door of the outer box is easy to operate, and the pressing block, spring and other structures make the disassembly and installation of the mounting plate simple and easy, which is convenient for internal repair and maintenance, ensuring the stable operation and long-term use of the equipment. The sample to be tested enters the connecting pipe through the solenoid valve and is transferred to the storage bottle. After closing the fourth solenoid valve, unscrew the threaded ring, take out the storage bottle, start the water pump, draw water from the water tank through the water pipe, clean the connecting pipe, and ensure that there is no residual sample in the pipe. The cleaned water is filtered through the filter and finally returned to the water tank for recycling. During maintenance, unscrew the sealing cover, take out the filter, clean it and then install it back to ensure the continued effectiveness of the system. For maintenance, open the door of the outer box, press the pressing block to squeeze the spring, and enter the specified position of the installation slot from the card slot. Then, you can take out the installation plate. After the maintenance is completed, use the above steps to install the installation plate back to ensure the normal operation of the equipment.
