Description

TECHNICAL FIELD

[0001] The utility model relates to VOCs collection equipment technical field, especially VOCs collector. BACKGROUND

[0002] Volatile organic compounds, which have high saturated vapor pressure, low boiling point and small molecular weight under standard conditions, are easily volatile at room temperature, and are one of the main atmospheric pollutants. VOC or VOCs is commonly used to represent, and TVOC is used to represent total volatile organic compounds. The wastewater discharged by numerous industrial enterprises and solid waste sites pollutes the soil along the way, and the exhaust gas is deposited on the ground with rain. Long-term irrigation with sewage and the use of herbicides in agricultural production result in the adsorption and absorption of different types and contents of pollutants in the soil. Through the action of rainwater, these pollutants leave the soil and enter surface runoff and groundwater, polluting the water body. Water pollutants enter the atmosphere through volatilization and other actions, and then re-enter the soil through sedimentation. The soil-water-atmosphere cycle pollutes the process, and the soil is the core link. Due to the strong activity of volatile organic compounds, they have obvious toxic effects on human health and agricultural production. Monitoring and research on volatile organic compounds in soil have become one of the hotspots of ecological environmental protection work.

[0003] In order to detect VOCs, a sampler for collecting volatile organic compounds in soil is disclosed in the utility model patent with the authorization announcement number CN218067113U. By setting the sampling cylinder and the push rod, the push rod is sleeved inside the sampling cylinder during use, the soil sample fills the sampling cylinder, the sampler is pulled out, and the soil sample is pushed into the soil sample bottle by the handle. However, the above-mentioned collector can determine the collection amount of soil according to the density of soil by setting multiple positioning holes and cooperating with positioning pins, but since the positioning pins are movable between the multiple positioning holes and any limiting or anti-loose structure is not set, when the personnel adjust the positioning pins to the specified positioning holes for soil collection, if the angle deviates, the positioning pins are easy to fall off from the positioning holes, causing the sampling cylinder to fall off, and the personnel need to re-adjust, resulting in low sampling efficiency during use.

[0004] Therefore, the utility model provides a VOCs collector to solve the above-mentioned problems in the prior art. UTILITY MODEL CONTENT

[0005] Therefore, the utility model provides a VOCs collector to solve the above-mentioned problems in the prior art.

[0006] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0007] A VOCs collector, comprising:

[0008] A collection cylinder;

[0009] A debugging assembly arranged on the upper surface of the collection cylinder, comprising:

[0010] A sleeve movably arranged on the upper end surface of the collection cylinder, and a clamping block arranged in the sleeve;

[0011] A spring arranged on one side of the clamping block;

[0012] A connecting block arranged in a rectangular array on the surface of the collection cylinder and matched with the clamping block;

[0013] A storage cylinder movably arranged in the collection cylinder.

[0014] In a preferred embodiment, a slot is arranged on the sleeve, the clamping block is movably connected to the slot hole of the sleeve through a rotating shaft, and the clamping blocks are symmetrically arranged on the sleeve.

[0015] In a preferred embodiment, an auxiliary wheel is movably connected in the slot hole of the sleeve through a rotating shaft.

[0016] In a preferred embodiment, a positioning cone is arranged on the top of each of the opposite sides of the clamping block, and the positioning cones are matched with the connecting block.

[0017] In a preferred embodiment, the lower end of the clamping block is inwardly protruded, and the lower end of the clamping block is in abutment with the upper surface of the connecting block.

[0018] In a preferred embodiment, a pulling hole is further arranged on the sleeve.

[0019] In a preferred embodiment, a pulling rope is arranged below each of the opposite sides of the clamping block, the pulling rope is in contact with the auxiliary wheel, the pulling rope extends to the outside of the sleeve, and the upper end of the pulling rope is connected with a pushing block.

[0020] In a preferred embodiment, the pushing block is vertically and slidingly connected to the outer side surface of the sleeve.

[0021] In a preferred embodiment, a guide rail is symmetrically arranged in the collection cylinder, and the guide rail is matched with the storage cylinder.

[0022] In a preferred embodiment, a plurality of resistance increasing blocks are arranged in an annular array in the storage cylinder, and the resistance increasing blocks are inverted triangular structures.

[0023] Compared with the prior art, the VOCs collector has the following beneficial effects:

[0024] 1. By adjusting the settings of the components, when workers collect soil, they only need to hold the sleeve and then lift the sleeve to the height of the collection tube surface according to the required amount of soil to be collected. After the adjustment is completed, the spring will automatically squeeze the locking block into the corresponding two connecting blocks to position the sleeve, which can prevent the collection tube from becoming loose during collection or transportation.

[0025] 2. By using a lifting rope in conjunction with a lever block, after personnel have collected soil from the outer wall, they only need to hold the lever block with their hand. At this time, the lifting rope can reset the locking block and allow the positioning cone above the locking block to insert into the two corresponding connecting blocks to fix the sleeve again, making it more stable when personnel pull the collection tube out of the soil.

[0026] 3. By incorporating a sliding storage cylinder within the sampling tube, the collected soil extends automatically beyond the tube after sampling, facilitating soil collection. Furthermore, multiple inverted resistance blocks within the storage cylinder compress the soil during sampling, preventing it from falling and affecting the sample volume. This design overcomes the shortcomings of traditional samplers, which lack positioning and anti-loosening mechanisms, leading to accidental detachment of the push rod from the sampling tube and impacting the overall stability and efficiency of the sampler.

[0044] For purposes of the description hereinafter, spatial

[0045] The detection principle of the VOC collector is that the detection of volatile organic compounds in soil usually needs multiple steps such as sample collection, pretreatment and analysis. First, the gas sample can be collected from the surface layer or different depths of the soil by the method of gas sampling. A soil gas extraction system such as a static head space method or a dynamic extraction method is generally used. The static head space method places the soil in a sealed container, and collects VOCs in the air in the container through an air sampler. The dynamic extraction method inserts an air extraction device into the soil, and extracts the gas from the soil through a pump. After sampling, the gas sample needs to be properly pretreated, and methods such as gas adsorption, condensation or solid adsorption tube are usually used to concentrate VOCs in the gas. The concentrated gas sample can be analyzed by techniques such as gas chromatography-mass spectrometry or gas chromatography-nitrogen phosphorus detector to identify and quantify the types and concentrations of VOCs. In GC analysis, the soil gas sample is usually first separated and detected. The GC column can effectively separate different VOCs, and the mass spectrometer or other detector can help to qualitatively and quantitatively analyze each component. Through the above steps, the content and types of VOCs in the soil can be accurately detected.
