Technical Field

[0001] The utility model relates to the technical field of samplers, and more specifically to a sampler used in chemical engineering. Background Art

[0002] Pure water changes its original physical or chemical properties after use, and becomes wastewater containing different types of impurities. Chemical wastewater is wastewater discharged in chemical production, such as process wastewater, cooling water, exhaust gas washing water, equipment and site flushing water, etc. If these wastewaters are discharged without treatment, they will cause different properties and different degrees of pollution in the water body, thereby endangering human health and affecting industrial and agricultural production.

[0003] The shortcomings of the existing technology: When sampling chemical wastewater microorganisms, the current sampler has a single sampling method and is troublesome to carry test tubes, which is difficult to meet people's usage needs. For this reason, we propose a sampler for chemical engineering. Utility Model Content

[0011] Technical effects and advantages of the utility model:

[0012] 1. The utility model can achieve the effect of facilitating the carrying of the test tube by placing the test tube in the storage groove opened on the upper end surface of the storage sleeve. After the test tube is stored in the storage groove, the first magnetic block and the second magnetic block are attracted to each other, so that the test tube can be fixed and stably stored in the storage groove, and at the same time, it can also provide a certain protection effect for the carrying of the test tube.

[0020] The utility model provides a sampler for chemical engineering, comprising a sampling tube 1, a piston 2 is fixedly and slidably connected in the sampling tube 1, a pull rod 3 is fixedly connected to the output end of the piston 2, a storage sleeve 4 is fixedly connected to the circumferential surface of the sampling tube 1, a storage groove 5 is opened on the upper end surface of the storage sleeve 4, a test tube 6 is arranged in the storage groove 5, a plug 7 is arranged in the test tube 6, an extraction port 8 is fixedly connected to the lower end of the sampling tube 1, and a filtering mechanism is arranged on the circumferential surface of the extraction port 8. When working, by placing the test tube 6 in the storage groove 5 opened on the upper end surface of the storage sleeve 4, the effect of facilitating carrying the test tube 6 can be achieved, and at the same time, a certain protection effect can be played on the carrying of the test tube 6. When extracting samples, by controlling the pull rod 3 to move upward, the pull rod 3 will drive the piston 2 to move upward, and the sample will be filtered once through the filtering mechanism, and most of the impurities in the water source sample will be filtered, so as to avoid clogging the sampling equipment.

[0021] Furthermore, a first magnetic block 9 is fixedly connected in the storage slot 5, and a second magnetic block 10 is fixedly connected to the lower end of the test tube 6. The first magnetic block 9 and the second magnetic block 10 are attracted to each other. During operation, after the test tube 6 is stored in the storage slot 5, the first magnetic block 9 and the second magnetic block 10 are attracted to each other, so that the test tube 6 can be fixed and stably stored in the storage slot 5.

[0022] Furthermore, an electric telescopic rod 11 is fixedly connected to the upper end of the sampling tube 1, and the output end of the electric telescopic rod 11 is slidably connected to the sampling tube 1, and the output end of the sampling tube 1 is slidably connected to the pull rod 3. When working, by controlling the operation of the electric telescopic rod 11, the electric telescopic rod 11 will drive the pull rod 3 to move upward, thereby achieving the effect of extracting samples. At the same time, after the extraction is completed, the filter head 12 can be removed, and the electric telescopic rod 11 can be controlled to operate again to drive the piston 2 to move downward, so that the sample can be discharged from the sampling tube 1 and stored in the test tube 6.

[0023] Furthermore, the filtering mechanism includes a filter head 12 fixedly connected to the circumferential surface of the extraction port 8, a filter chamber 13 is provided in the filter head 12, and a filter screen 14 is provided in the filter chamber 13.

[0025] Furthermore, the sampling tube 1 is made of a transparent material, and an observation port 16 is provided on the circumferential surface of the storage sleeve 4. During operation, since the sampling tube 1 is made of a transparent material, the sample extraction amount in the sampling tube 1 can be observed through the observation port 16.

[0026] The working principle of the utility model is as follows: by placing the test tube 6 in the storage slot 5 provided on the upper end surface of the storage sleeve 4, the test tube 6 can be easily carried. After the test tube 6 is stored in the storage slot 5, the first magnetic block 9 and the second magnetic block 10 are attracted to each other, so that the test tube 6 can be fixed and stably stored in the storage slot 5.

When extracting samples, by installing the filter head 12 on the extraction port 8, and then controlling the operation of the electric telescopic rod 11, the electric telescopic rod 11 will drive the pull rod 3 to move upward. Thereby, the effect of extracting samples is achieved. When extracting samples, the samples will first pass through the filter head 12, and then through the filter net 14 in the filter chamber 13, so that most of the impurities in the water source sample can be filtered out to avoid clogging of the sampling equipment. Since the sampling tube 1 is made of transparent material, the sample extraction amount in the sampling tube 1 can be observed through the observation port 16. After the extraction is completed, the filter head 12 can be removed, and the electric telescopic rod 11 can be controlled to operate again to drive the piston 2 to move downward, so that the sample can be discharged from the sampling tube 1 and stored in the test tube 6.
