Description

Technical Field

[0001] The utility model relates to the technical field of chemical material samplers, in particular to a sampler for chemical materials and chemical gases. Background Technique

[0002] Chemical sampling refers to the process of taking a certain amount of a part from a certain material in a chemical experiment or industrial production for subsequent chemical analysis or experimental use. The purpose of sampling is to obtain a representative sample so as to accurately and reliably analyze the overall properties of the material.

[0003] The materials used in the chemical test process include solid, liquid, and gaseous materials. In the current sampling methods, solid materials or powdered materials are directly taken with tweezers or spatulas, while liquid or gaseous materials need to be sampled using a sampler. Generally, a sampler can only collect liquids or gases singly, lacking a sampler with the function of collecting liquid and gas samples. Moreover, most samplers directly become the sample body after collecting the sample and cannot perform secondary sampling. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a sampler for chemical materials and chemical gases, which can sample and seal and collect liquid or gaseous materials, and is convenient for transporting and storing the samples after sampling.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a sampler for chemical materials and chemical gases, including a housing and a collection tank. The collection tank is a transparent tank body, which can be made of anti-corrosion transparent materials such as glass or plastic. Multiple collection tanks are provided for replacement use. Finger grooves are provided on the outer side of the housing. An installation groove is provided on one side of the housing. A slot is provided below the housing and below the installation groove. A fixing mechanism is provided on the upper side of the housing. After the collection tank is inserted into the installation groove, it is fixed in the slot through the fixing mechanism. A collection mechanism for material sampling is provided on the lower side of the housing. A sampling tube is connected and communicated below the collection tank. A negative pressure tube is connected and communicated on one side of the upper end of the collection tank. The negative pressure tube is connected to a syringe or a negative pressure device, so that the inside of the collection tank has the function of negative pressure attracting gas or liquid.

[0006] As an improvement, sealing valves are provided on both the sampling tube and the negative pressure tube.

[0007] As an improvement, the collection mechanism includes a lower head. An opening is provided on the side of the lower head. The sampling tube extends into the opening. A connecting tube inserted into the sampling tube is provided inside the head. A hopper communicated with the connecting tube is provided below the lower head. A sealing ring is provided on the lower side of the lower head.

[0008] As an improvement, the fixing mechanism includes a top plate, on which a lead screw is threadedly connected. A turning handle is provided at the upper end of the lead screw. A pressing plate is slidably arranged in the installation groove. The lead screw is rotatably connected to the middle of the pressing plate. An arc-shaped plate is arranged outside the pressing plate, and the arc-shaped plate is slidably connected to the top plate.

[0009] As an improvement, the lower end of the collection tank is funnel-shaped. The slot has a notch for the sampling tube to pass through. The slot is funnel-shaped and a rubber pad is arranged on the inner side.

[0010] The advantages of the present utility model are as follows: The collection tank is directly inserted into the installation groove. The pressing plate of the fixing mechanism moves downward to press and fix the collection tank inside the slot. The connecting pipe and the sampling tube are inserted and connected. Negative pressure is formed inside the collection tank through the negative pressure pipe to perform sample collection operations. Through the connection between the collection tank and the collection mechanism, the sampler can collect liquid and gas samples. The collected collection tank can be quickly sealed and separated from the housing, which is convenient for secondary sampling and can preserve and transport the collected samples.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following further describes the present utility model in detail with reference to the drawings.

[0017] Combined with the attached Figure 1 、 Figure 2As shown in the figure, a sampler for chemical materials and chemical gases includes a housing 1 and a collection tank 2. A finger groove 101 is provided on the outer side of the housing 1. An installation groove 3 is provided on one side of the housing 1. A slot 4 is provided below the housing 1 and below the installation groove 3. A fixing mechanism is provided on the upper side of the housing 1. After the collection tank 2 is inserted into the installation groove 3, it is fixed in the slot 4 through the fixing mechanism. A sampling mechanism for material sampling is provided on the lower side of the housing 1. The sampling mechanism includes a lower head 8. An opening 9 is provided on the side of the lower head 8. The sampling tube 5 extends into the opening 9. A connecting tube 10 inserted into the sampling tube 5 is provided inside the lower head 8. A hopper 11 communicating with the connecting tube 10 is provided below the lower head 8. A sealing ring 12 is provided on the lower side of the lower head 8. When the hopper 11 faces downwards, it can converge the gas for gas sampling. When the hopper 11 faces upwards, it can form a funnel for liquid sampling, realizing the dual-sample collection of liquid and gas. An inlet tube 5 is connected to the bottom of the collection tank 2. A negative pressure tube 6 is connected to one side of the upper end of the collection tank 2. The negative pressure tube 6 is connected to a syringe or a negative pressure device, so that the collection tank 2 has the function of sucking gas or liquid under negative pressure.
