Abstract
Description
Technical Field
[0001] This utility model relates to the field of high specificity sample sampling technology, specifically a high specificity sample sampling device. Background Technology
[0002] High specific surface area (SSPA) samples refer to materials with extremely high SSPA. These materials typically possess two notable characteristics: firstly, the particle surface has loose micropores; and secondly, the surface has numerous tiny gaps. Therefore, SSPA samples have a much larger surface area than ordinary materials, exhibiting a very high specific surface area. However, due to their large SSPA, they are prone to adsorbing impurities, leading to contamination during sampling and affecting the sample's properties. For example, oxidation and deliquescence reactions can occur during post-sampling transportation and contact with air, resulting in a decrease in the sample's specific surface area. Utility Model Content

[0022] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as the material of the sampling outer cylinder 1 and the sampling inner cylinder 2, the model of the heating plate, and how the heating plate is routed between the sampling outer cylinder 1 and the sampling inner cylinder 2.
[0023] Example 1
[0024] A sampling device for high specific surface area samples, such as Figure 1As shown, a cylindrical sampling box is included, comprising an outer sampling cylinder 1 and an inner sampling cylinder 2. Both the outer and inner cylinders have closed and open ends. The outer cylinder 1 is fixedly fitted onto the inner cylinder 2, and a heating assembly 3 is disposed between them. The heating assembly 3 includes a heating plate and wires fixedly disposed between the outer and inner cylinders. The wires are connected to the heating plate and then to a power source. This allows the heating plate to heat the high specific surface area sample inside the inner cylinder 2, while the presence of the heated outer cylinder prevents operators from accidentally touching the heating plate and being injured. The closed end of the outer cylinder 1 contacts the open end of the inner cylinder 2, such as... Figure 2 As shown, the outer sampling cylinder 1 has a first inlet, and the inner sampling cylinder 2 has a second inlet. The first and second inlets are connected to form a sampling channel. When the sampling box is placed in the sample pile for sampling, the high specific surface area sample can enter the inner sampling cylinder 2 from the sampling channel.
[0025] A baffle plate 6 is installed on the outer side of the sampling channel. An installation rod 9 is connected to the closed end of the sampling outer cylinder 1. A connecting rod 8 is movably connected to the installation rod 9 via a connector, and the connecting rod 8 is parallel to the installation rod 9. The connecting rod 8 is fixedly connected to the baffle plate 6, and when the connecting rod 8 moves relative to the installation rod 9, it can cause the baffle plate 6 to close or open the sampling channel. To ensure the sealing of the sampling channel when the baffle plate 6 closes, a sealing gasket is laid at the edge of the baffle plate 6.
[0026] The above are the basic embodiments of this utility model. Further improvements, optimizations, and limitations can be made based on the above to obtain the following embodiments:
[0027] Example 2
[0028] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2 and Figure 3 As shown, the connector includes a turntable 11 rotatably mounted on the mounting rod 9. The outer diameter of the turntable 11 is larger than the outer diameter of the sampling box. The connecting rod 8 is connected to the turntable 11. The connecting rod 8 is connected to the edge near the turntable 11 to ensure that the connecting rod 8 can remain parallel to the sampling box. During the rotation of the turntable 11, it can drive the connecting rod 8 and the baffle plate 6 to rotate, and the baffle plate 6 can close or open the sampling channel. When the sampling box is placed in the sample pile, the operator can hold the turntable 11 and rotate the baffle plate 6 after reaching the appropriate position.
[0029] Example 3
[0030] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 4 and Figure 5 As shown, the connector includes a sliding sleeve and an extension rod 15. The sliding sleeve is slidably fitted onto the mounting rod 9. One end of the extension rod 15 is fixedly connected to the sliding sleeve, and the other end is fixedly connected to the connecting rod 8. The extension rod 15 is provided with several limiting elements to restrict its sliding distance. During the sliding process, the extension rod 15 can drive the baffle plate 6 to close or open the material collection channel. When the sampling box is placed in the sample pile, the operator can hold the extension rod 15 or the mounting rod 9, reach a suitable position, and then take a sample. The extension rod 15 is then slid downwards until the baffle plate 6 closes the material collection channel. When the extension rod 15 is slid upwards away from the baffle plate 6, the limiting elements restrict the position of the extension rod 15, eliminating the need for the operator to continuously control the extension rod 15.
[0031] Example 4
[0032] This embodiment is an improvement on embodiment 3. Its main structure is the same as that of embodiment 3, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 4 and Figure 5 As shown, the limiting component includes two elastic limiting protrusions 16 disposed on the surfaces of the extension rod 15 and the mounting rod 9 that contact each other. The two elastic limiting protrusions 16 are symmetrically distributed about the axial direction of the mounting rod 9. The mounting rod 9 has multiple limiting grooves 17 along its length. During the movement of the extension rod 15, the elastic limiting protrusions 16 can be inserted into the corresponding limiting grooves 17. When the two elastic protrusions enter the limiting grooves 17 near the sampling box, the baffle plate 6 closes the material extraction channel; when the two elastic protrusions enter the limiting grooves 17 away from the sampling box, the baffle plate 6 opens the material extraction channel.
[0033] Example 5
[0034] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 1 As shown, the mounting rod 9 has a through groove along its length, extending to both end faces of the mounting rod 9. A push rod 10 slides through the through groove, allowing it to extend into the interior of the outer sampling cylinder 1 and the inner sampling cylinder 2. A push plate 4 is connected to the portion of the push rod 10 extending into the inner sampling cylinder 2, with the edge of the push plate 4 contacting the inner wall of the inner sampling cylinder 2. As the push rod 10 moves within the through groove, it can change the position of the push plate 4 within the inner sampling cylinder 2. This allows for changing the volume of the inner sampling cylinder 2 used to accommodate high specific surface area samples, and the push plate 4 can scrape off the high specific surface area samples adhering to the inner wall of the inner sampling cylinder 2 as it slides up and down.
[0035] Example 6
[0036] This embodiment is an improvement on embodiment 5. Its main structure is the same as that of embodiment 5, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 1 As shown, in order to control the volume of high specific surface area sample without the operator having to constantly control the push rod 10 connected to the push plate 4, the push rod 10 is provided with multiple elastic positioning protrusions 14, and the mounting rod 9 is provided with positioning through holes 13 corresponding to the elastic positioning protrusions 14.
[0037] Example 7
[0038] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 1 As shown, a limiting plate 12 is provided at the end of the push rod 10 away from the sampling box to prevent the push rod 10 from completely entering the through groove.
[0039] Example 8
[0040] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2 and Figure 4 As shown, to avoid the material removal channel not being completely closed because the material removal channel is not visible when the material removal channel is in the sample pile, a limiting block 7 is provided in the sampling outer cylinder 1, and the limiting block 7 is close to the material removal channel. When the material removal channel is closed, the material removal channel can be in contact with the limiting block 7.
[0041] Example 9
[0042] This embodiment is an improvement on embodiment 1. Its main structure is the same as that of embodiment 1, but the improvement lies in: [The following is a more detailed description of the improvement.] Figure 2 and Figure 4 As shown, a cone 5 is detachably mounted on the bottom of the sampling box. The large end of the cone 5 is connected to the bottom of the outer sampling cylinder 1, and the bottom of the inner sampling cylinder 2 has a discharge channel communicating with the cone 5. When it is necessary to discharge the high specific gravity sample, the cone 5 is removed, and the high specific gravity sample is discharged from the discharge channel. The connection between the cone 5 and the sampling box is conventional technology in this field and will not be described in detail here.
