Description

Technical Field

[0001] This utility model relates to the field of desulfurizing agent detection technology, and in particular to a sampling device for detecting composite iron oxide desulfurizing agents. Background Technology

[0002] Desulfurizing agents generally refer to agents that remove free sulfur or sulfur compounds from fuels, raw materials, or other materials. Composite iron oxide desulfurizing agents are solid desulfurizing agents that can desulfurize in the presence or absence of oxygen. Their principle is to chemically adsorb sulfur-containing compounds in the exhaust gas into the pores of the desulfurizing agent, changing its chemical composition and thus purifying the gas. After long-term storage or prolonged use, composite iron oxide desulfurizing agents may experience reduced activity or even deactivation; therefore, their activity needs to be tested periodically, requiring the use of a sampling device.

[0003] Traditional sampling devices are relatively simple, typically involving inserting a sampling tube with a side opening to the required depth of the desulfurizing agent. However, because the sampling port is always exposed, this method allows desulfurizing agent from other depths to mix in, resulting in inaccurate samples and affecting detection precision. Furthermore, composite iron oxide desulfurizing agents at deeper locations may be tightly bound due to pressure and other factors; simply inserting the sampling tube may result in insufficient sample entering, negatively impacting the required detection. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a composite iron oxide desulfurizer detection and sampling device that addresses the above-mentioned technical deficiencies. This device can conveniently open or close the sampling port during the sampling process, avoiding the mixing of desulfurizer at non-specified depths and improving the accuracy of sample detection.

[0005] The technical solution adopted by this utility model is as follows: a composite iron oxide desulfurizer detection and sampling device is provided, including a vertically arranged sampling shell; multiple isolation blocks are evenly distributed from top to bottom inside the sampling shell; the multiple isolation blocks divide the inside of the sampling shell into multiple material collection chambers; the side wall of the sampling shell has a feed inlet that corresponds to and communicates with the material collection chambers; and an opening and closing component is provided inside the sampling shell. The opening and closing assembly includes a slide rod vertically disposed inside the sampling shell; the slide rod slides through multiple isolation blocks in sequence with corresponding sliding seals; the upper end of the slide rod slides through the upper end of the sampling shell with a sliding seal; multiple sealing plates are fixed on the slide rod; each sealing plate corresponds to a feed inlet; the vertical sliding of the slide rod is used to drive the sealing plates to open or close the feed inlet.

[0006] To further optimize this technical solution, a vertical partition is fixed inside the sampling shell of a composite iron oxide desulfurizer detection and sampling device; the material collection chamber is located on the left side of the partition; the right side of the sampling shell is divided into an action chamber by the partition; a material feeding assembly is provided inside the action chamber. The material-feeding assembly includes a vertically arranged connecting rod; the upper end of the connecting rod slides and seals through the upper end of the sampling shell; multiple wedge-shaped push blocks are fixed vertically along the connecting rod; multiple stops corresponding to the push blocks are arranged from top to bottom in the action chamber; a material-feeding rod is fixed to the left side of the stop block and an action spring is fixed to the right side; the material-feeding rod slides and seals through the partition in the left-right direction; the material-feeding rod corresponds to the feed inlet; the left end of the action spring is connected to the stop block and the right end is connected to the right side of the sampling shell; the action spring is configured with a pre-spring force to extend the material-feeding rod from the corresponding feed inlet; the vertical sliding of the connecting rod is used to push the stop block with the push block, causing the material-feeding rod to retract into the collection chamber.

[0007] To further optimize this technical solution, a sampling device for detecting composite iron oxide desulfurizer has a hole seat fixed at the upper end of the slide rod and the upper end of the connecting rod, respectively; a vertical adjusting screw is threaded into the hole seat; two shaft seats are fixed at the upper end of the sampling shell; the adjusting screw is rotatably connected to the shaft seat in a one-to-one correspondence.

[0008] To further optimize this technical solution, a filling block is fixed at the angle between the lower side of the inlet and the isolation block inside the collection chamber of a composite iron oxide desulfurizer detection and sampling device; the outer side of the filling block has an inclined surface structure.

[0009] To further optimize this technical solution, a cone-shaped head is fixed at the lower end of the sampling shell of a composite iron oxide desulfurizer detection and sampling device.

[0010] The beneficial effects of this utility model are as follows: Multiple collection chambers distributed at varying heights allow for the separate sampling of composite iron oxide desulfurizer at various depths, meeting the needs of multi-depth sampling. The inlet allows desulfurizer samples to enter and be collected within the collection chambers. A sliding rod drives a sealing plate to move vertically, opening or closing the inlet. This external control of the inlet opening and closing prevents desulfurizer from prematurely entering the collection chamber before reaching the designated depth, or from mixing desulfurizer from other depths when the device is pulled out after sampling, thus improving sampling accuracy.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1 As shown, a composite iron oxide desulfurizer detection and sampling device includes a vertically arranged sampling shell 1; multiple isolation blocks 2 are evenly distributed from top to bottom inside the sampling shell 1; the multiple isolation blocks 2 divide the interior of the sampling shell 1 into multiple material collection chambers 3; the side wall of the sampling shell 1 has a feed inlet 4 that corresponds to and communicates with the material collection chambers 3; the sampling shell 1 is equipped with an opening and closing component. The opening and closing assembly includes a slide rod 5 vertically disposed inside the sampling shell 1; the slide rod 5 sequentially slides through multiple isolation blocks 2 in a corresponding manner; the upper end of the slide rod 5 slides through the upper end of the sampling shell 1; multiple sealing plates 6 are fixed on the slide rod 5; the sealing plates 6 correspond one-to-one with the feed inlet 4; the vertical sliding of the slide rod 5 is used to drive the sealing plates 6 to open or close the feed inlet 4.

[0015] Before sampling, the slide bar 5 is moved to block the inlet 4 by the sealing plate 6. When the sampling shell 1 is inserted into the desulfurizer, no desulfurizer will enter the collection chamber 3 in advance. Only when the corresponding collection chamber 3 reaches the specified depth (the insertion depth can be determined by setting a mark on the sampling shell 1 in advance or by setting a scale on the sampling shell 1), the slide bar 5 is slid in the opposite direction again to release the sealing plate 6 from the inlet 4. At this time, the desulfurizer sample at the corresponding depth enters the collection chamber 3. After a period of time, the sealing plate 6 is used to block the inlet 4 again, and the sampling shell 1 can be taken out. At this time, no desulfurizer from other locations will be mixed in.

[0016] The above method enables precise sampling of the composite iron oxide desulfurizer at a specified depth, avoiding contamination by desulfurizer from other depths and resulting in more accurate test results. The multiple collection chambers 3 on the sampling shell 1 allow for multi-level sampling within the corresponding depth range, enabling comparative testing of multiple samples at that depth and improving the verifiability of the test results.

[0017] like Figure 1-2 As shown, a partition 7 is fixed vertically inside the sampling shell 1; the material collection chamber 3 is located to the left of the partition 7; the right side of the sampling shell 1 is divided into an action chamber 8 by the partition 7; a material feeding assembly is provided inside the action chamber 8. The material-feeding assembly includes a vertically arranged connecting rod 9; the upper end of the connecting rod 9 slides and seals through the upper end of the sampling shell 1; multiple wedge-shaped push blocks 10 are fixed vertically along the upper edge of the connecting rod 9; multiple stops 11, corresponding one-to-one with the push blocks 10, are arranged from top to bottom in the action chamber 8; a material-feeding rod 12 is fixed to the left side of the stop block 11, and an action spring 13 is fixed to the right side; the material-feeding rod 12 slides and seals through the partition 7 in the left-right direction; the material-feeding rod 12 corresponds one-to-one with the feed inlet 4; the left end of the action spring 13 is connected to the stop block 11, and the right end is connected to the right side of the sampling shell 1; the action spring 13 is configured with a pre-spring force to extend the material-feeding rod 12 from the corresponding feed inlet 4; the vertical sliding of the connecting rod 9 is used to push the stop block 11 with the push block 10, causing the material-feeding rod 12 to retract into the collection chamber 3.

[0018] Because the composite iron oxide desulfurizing agent in deeper locations may be tightly bound due to pressure and other issues, simply inserting the sampling shell 1 may result in insufficient sample entering, which could adversely affect the required testing.

[0019] Therefore, this solution is equipped with a material-pumping component. When the feed inlet 4 reaches the specified depth and opens, the spring force of the action spring 13 is used to push the material-pumping rod 12 out of the feed inlet 4. The material-pumping rod 12 applies a force to the desulfurizer, and the tightly packed desulfurizer can be impacted and shaken apart, and then enter the collection chamber 3 through the feed inlet 4 to ensure sufficient sample collection.

[0020] When the material pusher rod 12 needs to retract into the material collection chamber 3, the sliding action of the connecting rod 9 causes the wedge-shaped pusher block 10 to push the stop block 11 to move laterally, which gradually drives the material pusher rod 12 back into the material collection chamber 3.

[0021] like Figure 1 As shown, the upper ends of the slide rod 5 and the connecting rod 9 are respectively fixed with hole seats 14; vertical adjusting screws 15 are threaded into the hole seats 14; two shaft seats 16 are fixed at the upper end of the sampling shell 1; the adjusting screws 15 and shaft seats 16 are rotatably connected in a one-to-one correspondence.

[0022] The sliding action of connecting rod 9 and slide rod 5 can be achieved by turning the corresponding adjusting screw 15, which makes it easier to control the sliding amount more precisely and convenient to position, making the sampling operation more convenient.

[0023] like Figure 1-2 As shown, a filling block 17 is fixed at the angle between the lower side of the inlet 4 inside the collection chamber 3 and the isolation block 2; the outer surface of the filling block 17 is an inclined surface structure. The filling block 17 is designed to facilitate the pouring out of the sample after sampling, effectively avoiding desulfurizing agent residue and preventing residual desulfurizing agent from interfering with subsequent sampling.

[0024] like Figure 1As shown, a conical head 18 is fixed to the lower end of the sampling shell 1. The conical head 18 makes it easier to insert the desulfurizing agent into the sampling shell 1 without the need for external special tools.
