Description

Technical Field

[0001] The utility model relates to the technical field of water quality detection, in particular to a halogen-adsorbable pre-treatment device for water quality detection. Background Art

[0002] During water quality testing, the organic halogens in the water will be adsorbed in the activated carbon, which is then placed in a high-temperature furnace for combustion and decomposition, converting the adsorbable halogens into hydrogen halides, which are absorbed by alkaline aqueous solution and measured by ion chromatography. The activated carbon needs to be cleaned after use.

[0003] The invention with the authorization publication number CN106442040A provides a pretreatment device for adsorbable halogen for water quality testing, which belongs to the technical field of "water quality testing" and the protected claims: "It includes an adsorption and filtration device and a combustion device, and the pretreatment device also includes a column, a lifting sleeve is vertically slidably installed on the column, and a flip seat is rotatably installed on the lifting sleeve around the horizontal rotation center line, and a connecting sleeve is provided on the flip seat, and an activated carbon column is detachably installed on the connecting sleeve, and the connecting nozzle of the sample tube is provided with a sealing structure; the connecting sleeve is provided with a negative pressure exhaust port, and the negative pressure exhaust port is connected to the suction device; the combustion boat is connected to a horizontal drive device, and a docking port is provided on the combustion boat, and the connecting sleeve is provided with a discharge mechanism that facilitates pouring the activated carbon in the activated carbon column into the combustion boat. The entire process of the pretreatment device is fully automated, which improves efficiency and reduces labor costs."

[0004] Although this device can automatically adsorb halogens and process activated carbon at the same time, the activated carbon in the device is not sealed during the transfer process, so residual samples will drip out, causing pollution and making it difficult to clean. For this reason, we propose a pretreatment device that can adsorb halogens for water quality testing. Utility Model Content

[0025] The processing component 2 includes an output pipe 201, a processing pipe 202 and activated carbon 205; the output pipe 201 is fixedly connected to the output end of the positive pressure component 3; the processing pipe 202 is threadedly connected to one end of the output pipe 201, and the outside of the processing pipe 202 is fixedly connected to a folding pipe 203, and the inside of the folding pipe 203 is fixedly connected to a positioning rod 204; the activated carbon 205 is slidably connected to the inside of the processing pipe 202, and a positioning hole 206 is opened on the outside of the activated carbon 205, and the positioning rod 204 is movably inserted into the positioning hole 206.

[0026] During specific implementation, distilled water is input into the cylinder 301, and then the fixing ring 10 is removed, the four folding tubes 203 are pulled out, and the positioning rod 204 is pulled out from the positioning hole 206 at the same time. At this time, the activated carbon 205 changes from a fixed state to an active state, and the distilled water is pushed by positive pressure to push the active carbon into the combustion chamber 8 for combustion treatment. During this process, the residual sample will not drip out, will not cause pollution, and does not need to be cleaned.

[0027] like Figure 1 As shown, further, one end of the connecting pipe 5 is fixedly connected to the combustion chamber 8, and one side of the combustion chamber 8 is fixedly connected to the pump body 9.

[0028] In specific implementation, by setting up the pump body 9 to generate negative pressure, the movement speed of the activated carbon 205 can be accelerated. The pumping end of the pump body 9 and the end of the connecting pipe 5 are detachably connected to avoid damage to the pump body 9 during combustion.

[0029] Example 2

[0030] On the basis of the first embodiment, in order to compensate for the problem of sample transportation in the first embodiment, a positive pressure component 3 is provided.

[0031] like Figure 2 As shown, the positive pressure assembly 3 includes a cylinder 301 and a rod 303; the cylinder 301 is fixedly connected to the upper end of the frame, and a piston 302 is slidably connected inside the cylinder 301; the rod 303 is fixedly connected to the upper end surface of the piston 302, and a hydraulic rod 304 is fixedly connected to the base frame 1, and the driving end of the hydraulic rod 304 is fixedly connected to the upper end of the rod 303; an input pipe 4 is provided in the cylinder 301, and one end of the input pipe 4 extends into the piston 302.
