Technical Field
[0001] This application relates to a chemical apparatus, and more particularly to a chemical sampling apparatus. Background Technology
[0002] Chemicals refer to various chemical substances produced in industry, and can exist in gaseous, liquid, or solid forms. Testing chemicals allows us to determine the quality of an entire batch, preventing poor quality from affecting the yield of subsequent production processes.
[0003] However, when chemicals are sampled for testing, the sampling area must maintain a certain level of cleanliness. Furthermore, during the chemical testing process, personnel performing the sampling are also susceptible to injury from contact with the chemicals.
[0004] In view of this, in order to improve and solve the above-mentioned deficiencies, the applicant has devoted himself to research and applied theoretical principles, and finally proposed a design that is reasonable and effective in improving the above-mentioned deficiencies. Utility Model Content
[0005] The main objective of this application is to provide a chemical sampling device that allows chemicals to be tested in a clean environment with a certain standard during the sampling and testing process, while ensuring the safety of the operators.
[0006] To achieve the above objectives, this application provides a chemical sampling device, including an operating table, a glove box, a supply unit, a cleaning unit, and a purification unit. The operating table has an operating side and a sampling side, and an operating space and a sampling space are provided within the operating table. The operating space and the sampling space are adjacent to and communicate with each other, with the operating space corresponding to the operating side and the sampling space corresponding to the sampling side. A normally closed valve is provided at the point where the operating space and the sampling space communicate with each other. The glove box is located within the operating space. The supply unit is located within the operating space and is used to supply chemicals. The cleaning unit is located within the operating space and is used to supply cleaning liquid. The purification unit is located within the operating space and is used to provide protective gas.
[0007] By employing the aforementioned structural composition of this application, it is possible to effectively ensure that operators do not directly contact the chemicals, thus guaranteeing their safety. At the same time, the chemicals are protected from contamination during the extraction process, thereby ensuring the accuracy of the laboratory test results. Attached Figure Description

[0029] To further disclose the features and technical content of this application, please refer to the following detailed description and accompanying drawings. However, the accompanying drawings are for reference and illustration only and are not intended to limit this application.
[0030] Please see Figure 1 , Figure 2 and Figure 3 These are, respectively, a perspective view of the exterior of the device from one viewpoint, a perspective view of the exterior of the device from another viewpoint, and a partial side sectional view of its internal structure. This application provides a chemical sampling device, including an operating table 1, a glove box 2, a supply unit 3, a cleaning unit 4, and a purification unit 5; wherein:
[0031] The operating console 1 can be a vertical machine, cabinet, or chassis, and other control systems such as computers and their screens can be installed on it. The operating console 1 has an operating space 10 and a sampling space 11, which are adjacent to and connected. A normally closed valve 12 is provided at the point where the operating space 10 and the sampling space 11 connect, allowing them to communicate when needed. Furthermore, the operating console 1 has an operating side 100 and a sampling side 110. The operating space 10 corresponds to the operating side 100, and the sampling space 11 corresponds to the sampling side 110. The operating side 100 can be opposite to the sampling side 110 (e.g., ...). Figure 1 and Figure 2 As shown), they can also be located on the same side of the operating table 1 and adjacent to each other (figure omitted); in the embodiment of this application, the operating space 10 and the sampling space 11 are located at a height position that allows the human body to operate with both hands in a standing posture, and the valve 12 can be a sliding door that can be opened or closed by sliding laterally.
[0032] The glove box 2 is located within the operating space 10 of the aforementioned operating table 1, and the operating space 10 forms part of the box body of the glove box 2. It includes a visible partition 20 and a pair of gloves 21 mounted on the partition 20. The partition 20 is made of transparent material, allowing the viewer to see into the operating space 10 from the outside. The partition 20 is located on the operating side 100 to cover the operating space 10, allowing the gloves 21 to be positioned within the operating space 10. This facilitates chemical sampling and other operations performed by a person standing outside the operating side 100 using the gloves 21 within the operating space 10. Furthermore, an inspection door 111 can be provided outside the sampling space 11 of the aforementioned operating table 1. When closed, the door allows viewing into the sampling space 11 from outside the operating table 1, and can be opened to access empty sampling bottles 30 or retrieve sampling bottles 30 containing chemicals.
[0033] The supply unit 3 can be a chemical supply nozzle and is located within the operating space 10. Preferably, it is located above the operating space 10, allowing the operator to use gloves 21 to pick up an empty sampling bottle 30 and draw the required chemical from the supply unit 3. The supply unit 3 draws the chemical from a chemical supply source (not shown) via a connection such as a pipeline. The supply source (not shown) can be a container for holding the chemical and can be located elsewhere on the operating table 1 or outside the operating table 1 to provide the supply unit 3 with the chemical to be sampled.
[0034] Multiple cleaning units 4 may be installed within the operating space 10. A water supply line may be provided to supply cleaning liquid, which may be pure water. Preferably, the cleaning unit 4 may be located on any side of the operating space 10 or above any side. The empty sampling bottle 30 can be cleaned by supplying a cleaning liquid such as pure water through the cleaning unit 4, thereby preventing contamination of the collected chemicals.
[0035] The clean unit 5 is located within the operating space 10 and is used to provide a protective gas, which may be nitrogen (N2). The protective gas fills the operating space 10 to maintain its environmental cleanliness, thereby preventing the chemicals from being contaminated during the extraction process.
[0036] Therefore, the chemical sampling device of this application can be obtained by means of the above-described structure.
[0037] like Figure 4 As shown, the sampling personnel at the sampling side 110 of the above-mentioned operating table 1 can open the inspection door 111 and put the empty sampling bottle 30 into the sampling space 11, and can take out the sampling bottle 30 containing chemicals in the sampling space 11.
[0038] Next, as Figure 5 and Figure 6 As shown, the operator at the operating side 100 of the operating table 1 will put their hands inside the gloves 21 to perform the operation. First, the valve 12 can be opened to remove the empty sampling bottle 30 from the sampling space 11 to the operating space 10, and then the valve 12 can be closed. At this time, the operator at the operating side 100 can use the cleaning unit 5 to fill the operating space 10 with protective gas, and use the cleaning unit 4 to clean the empty sampling bottle 30. After the cleaned sampling bottle 30 is used to draw the required chemicals by the supply unit 3, the valve 12 is opened again to place the sampling bottle 30 containing the chemicals into the sampling space 11, and wait for the operator at the sampling side 110 to take it. In this way, both the operator and the sampling personnel can be safely protected under this application and will not directly contact the chemicals. At the same time, the chemicals can be kept uncontaminated during the drawing process to ensure the accuracy and consistency of the test quality.
[0039] In conclusion, this application does indeed achieve the purpose described in the above specification and resolves the known deficiencies, fully meeting the requirements for a utility model patent application. Therefore, this application is filed in accordance with the Patent Law to protect the applicant's rights.
[0040] However, the above description is only a preferred embodiment of this application and does not limit the patent scope of this application. Therefore, all equivalent structural changes made using the content of this application's specification and drawings are also included within the protection scope of this application and are hereby stated.
