Description

Technical Field

[0001] The utility model relates to the technical field of glass-lined sampling, in particular to a glass-lined sampling device. Background Art

[0002] In the chemical, pharmaceutical, food and other industries, glass-lined equipment is widely used due to its excellent corrosion resistance, smooth surface and easy cleaning. During the operation of these equipment, in order to monitor the state and properties of the materials inside, sampling and analysis are often required. However, the traditional glass-lined sampling method mainly relies on manual operation, that is, using a sampling tube to extend into the interior of the glass-lined equipment for sampling.

[0003] Existing glass-lined sampling tubes are usually designed with fixed or adjustable lengths to meet the sampling requirements of different depths. However, in actual use, due to factors such as liquid level fluctuations and changes in material properties inside the glass-lined equipment, the location of the sampling point needs to be frequently adjusted. At this time, if a fixed-length sampling tube is used, it will not be able to adapt to such changes, thus affecting the accuracy and representativeness of the sampling.

[0004] For sampling tubes with adjustable length, although the length of the sampling tube can be changed by manual adjustment, this method has many inconveniences. First, manual adjustment requires a lot of manpower and time, which reduces work efficiency. Secondly, due to the complex internal environment of glass-lined equipment, there may be dangerous factors such as high temperature, high pressure, toxicity and harm, and manual adjustment of the sampling tube has certain safety risks. In addition, the accuracy of manual adjustment is limited, which is difficult to meet the requirements of high-precision sampling. Utility Model Content

DETAILED DESCRIPTION

[0024] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0025] See also Figure 1-5 , an embodiment provided by the utility model:

[0026] A glass-lined sampling device comprises a mounting cover 1, a connecting ring 112 is fixedly mounted on the bottom end of the mounting cover 1, and the outer surface of the connecting ring 112 is wrapped with rubber, a limiting tube 311 is fixedly mounted on the bottom end of the mounting cover 1, and a sampling tube 2 is movably mounted on the inner wall of the limiting tube 311, a connecting block 214 is fixedly mounted on the outer surface of one end of the sampling tube 2, two groups of fixed tubes 211 are fixedly mounted on the outer surface of the bottom end of the mounting cover 1, and electric push rods 212 are fixedly mounted on the inner walls of the two groups of fixed tubes 211, a connecting block 213 is fixedly mounted on one end of the electric push rod 212, and a fixing rod 215 is connected to one side of the connecting block 213, and one end of the fixing rod 215 is connected to the connecting block 214, one end of the sampling tube 2 is connected to a rubber tube 3, and one end of the rubber tube 3 is connected to a vacuum pump 4, one end of the vacuum pump 4 is connected to a connecting tube 5, and one end of the connecting tube 5 is connected to a liquid accumulation tank 6.

[0027] Furthermore, a movable cover 7 is movably installed on the top of the liquid collection tank 6. The movable cover 7 allows the user to easily open and close the liquid collection tank 6, thereby conveniently cleaning, maintaining and disinfecting the interior to keep the equipment clean and hygienic. When the sample is collected, by closing the movable cover 7, the sample can be effectively prevented from being contaminated by the outside world, thereby maintaining the purity and accuracy of the sample.

[0028] Furthermore, support bases 8 are fixedly installed on both sides of the vacuum pump 4, and the support bases 8 can stably support the vacuum pump 4 to prevent it from shaking or shifting during operation.

[0029] Furthermore, an electronic valve 9 is provided at one end of the rubber tube 3 . The addition of the electronic valve 9 enables the user to precisely control the on-off of the rubber tube 3 , thereby precisely controlling the flow of the sample.

[0030] Furthermore, a charging port 111 is provided on an outer surface of one side of the mounting cover 1. The design of the charging port 111 enables the user to conveniently charge the sampling device without disassembling the device or looking for a specific charging device, thereby improving the convenience of use.

[0031] Furthermore, fixing plates 216 are connected to both sides of the fixing rod 215, and the fixing plates 216 are fixedly connected to the connecting block 214 by bolts 217. The connection between the fixing plates 216 and the bolts 217 enhances the connection strength between the fixing rod 215 and the connecting block 214, thereby improving the structural stability of the entire sampling device. The connection with the bolts 217 makes the connection between the fixing rod 215 and the connecting block 214 more flexible, which is convenient for users to install, disassemble and repair, thereby improving the maintainability of the equipment.

[0032] Furthermore, the bottom end of the liquid collection tank 6 is serrated, and the outer surface of the liquid collection tank 6 is wrapped with rubber. The serrated design of the bottom end of the liquid collection tank 6 can increase the friction with the placement surface, prevent sliding or tipping due to external force during the sampling process, and improve the stability of the equipment. The rubber-wrapped outer surface can reduce the friction and collision between the liquid collection tank 6 and the placement surface, reduce damage to the equipment, and also play a certain buffering role.

[0033] Working principle: First, the installation cover 1 is tightly covered on the sampling port of the glass-lined equipment to ensure that the connection between the sampling device and the equipment is sealed reliably. The connection ring 112 at the bottom of the installation cover 1 forms a tight fit with the sampling port through the rubber material wrapped on its outer surface, further enhancing the sealing. At the beginning of the sampling operation, the sampling tube 2 is moved up and down in the limiting tube 311 by controlling the extension and contraction of the electric push rod 212. One end of the electric push rod 212 is fixedly connected to the connecting block 213, and the connecting block 213 is connected to the connecting block 214 at one end of the sampling tube 2 through the fixing rod 215. This connection method ensures that the sampling tube 2 can smoothly and accurately adjust its sampling position inside the equipment under the drive of the electric push rod 212. Once the sampling tube 2 is adjusted to a suitable sampling position, the vacuum pump 4 is started. The vacuum pump 4 is connected to the sampling tube 2 through the rubber tube 3, and the material sample inside the glass-lined equipment is sucked into the sampling tube 2 by negative pressure. Subsequently, the sample enters the connecting tube 5 through the rubber tube 3 and finally flows into the liquid storage tank 6 for collection. During the entire sampling process, since the position of the sampling tube 2 can be accurately adjusted by the electric push rod 212, the accuracy and representativeness of the sampling can be ensured. At the same time, the automated operation of the electric push rod 212 also greatly improves the sampling efficiency and reduces the safety risks of manual operation.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
