Description

Technical Field

[0001] This utility model belongs to the field of activated carbon desorption technology, and specifically relates to a stainless steel chloride test tube. Background Technology

[0002] Activated carbon, as a high-performance adsorbent, has been developed into various desorption materials with diverse qualities and functions, finding wide applications in multiple sectors of society. However, as the uses of activated carbon have expanded, the industry's technology and equipment for testing its quality performance have lagged behind, severely hindering its development. Desorption capacity is one of the essential indicators for judging the quality of activated carbon, primarily examining its desorption efficiency after adsorption gas saturation.

[0003] Currently, in existing activated carbon desorption testing equipment, activated carbon test tubes are mostly placed vertically for convenience of activated carbon filling. After filling, the activated carbon accumulates at the bottom of the test tube, and then the activated carbon in the test tube is heated by hot air flow or external heating ring. However, this arrangement, with the activated carbon accumulating at the bottom of the test tube, easily causes uneven heating of the activated carbon, affecting the accuracy of activated carbon desorption testing.

[0004] Therefore, this application provides a stainless steel chloride test tube, which facilitates placing the activated carbon to be desorbed in the middle of the test tube, making it convenient to heat it subsequently, ensuring the uniformity of heating, and avoiding damage to the mating parts at both ends of the test tube by heating.

[0009] The connecting sleeve is provided with a locking component for locking the limiting piston rod.

[0010] Furthermore, the connecting sleeve has a test tube cavity and a connecting rod cavity that are interconnected in the middle. The test tube cavity is fitted with the outer wall of the test tube body, and the connecting rod cavity is fitted with the limiting piston rod. The bottom of the test tube cavity is a stepped surface, which is used to abut against the end face of the test tube body.

[0011] Furthermore, the locking component is a locking bolt, and the connecting sleeve has a threaded hole, on which the locking bolt is threadedly connected. The locking bolt is used to lock the limiting piston rod.

One end of the connecting rod located in the receiving cavity is threadedly connected to a piston head, and the other end is fixedly connected to a handle. Several graduated rings are equidistantly arranged on the outer surface of the connecting rod.

[0013] Furthermore, the size of the piston head is adapted to the receiving cavity, and a sealing groove is provided on the outer surface of the piston head, with a sealing ring disposed in the sealing groove.

[0014] Furthermore, the filling funnel includes: a funnel body and a funnel neck, wherein the funnel body is conical and the funnel neck is tubular and connected to the end of the funnel body with a smaller diameter;

[0015] The neck is sleeved on the outside of the test tube body, and a mating groove is provided at the end of the inner cavity of the neck adjacent to the body, which is used to engage the end of the test tube body.

[0019] 1. The stainless steel chloride test tube of this utility model provides a standardized reaction space for activated carbon desorption through the through-hole accommodating cavity in the middle of the test tube body. Combined with the sliding control of the limiting piston rod, the position of the filler can be accurately positioned, avoiding the impact of excessive filler position deviation on subsequent heating desorption. The locking component on the connecting sleeve can lock the limiting piston rod. This design gives the limiting piston rod flexibility and stability. When it is necessary to adjust the filler position or remove the limiting piston rod, the lock can be released. After the position of the limiting piston rod is determined, it is fixed by the locking component to ensure that the limiting piston rod will not move during the filling process, ensuring that the filler is located in the middle of the accommodating cavity.

[0020] 2.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0035] like Figure 1-2 As shown, a stainless steel chloride test tube includes: a test tube body 1, a receiving cavity is provided through the middle of the test tube body 1, a connecting sleeve 2 is sleeved at one end of the test tube body 1, and a packing funnel 4 is sleeved at the other end.

[0036] The connecting sleeve 2 is slidably connected to a limiting piston rod 3 in the middle. The limiting piston rod 3 is used to restrict the packing inside the receiving cavity to be located in the middle of the receiving cavity. The packing funnel 4 is used to assist the packing in entering the receiving cavity.

[0037] The connecting sleeve 2 is provided with a locking component for locking the limiting piston rod 3.

[0038] The through-hole cavity in the middle of the test tube body 1 provides a standardized reaction space for activated carbon desorption. Combined with the sliding control of the limiting piston rod 3, the position of the packing material can be accurately positioned, avoiding excessive displacement of the packing material position from affecting subsequent heating and desorption. The locking component on the connecting sleeve 2 can lock the limiting piston rod 3. This design gives the limiting piston rod 3 flexibility and stability. When it is necessary to adjust the position of the packing material or remove the limiting piston rod 3, the lock can be released. After the position of the limiting piston rod 3 is determined, it is fixed by the locking component to ensure that the limiting piston rod 3 will not move during the packing process, ensuring that the packing material is located in the middle of the cavity.

[0039] like Figure 3 As shown, the connecting sleeve 2 has a test tube cavity 201 and a connecting rod cavity 202 that are interconnected in the middle. The test tube cavity 201 is engaged with the outer wall of the test tube body 1, and the connecting rod cavity 202 is engaged with the limiting piston rod 3. The bottom of the test tube cavity 201 is a stepped surface 205, which is used to abut against the end face of the test tube body 1.

[0040] The test tube cavity 201 facilitates the fitting or removal of the connecting sleeve 2 from the test tube body 1. After filling is completed, the connecting sleeve 2 and the limiting piston rod 3 can be directly removed from the test tube body 1, simplifying the filling operation steps.

[0041] like Figure 3-4 As shown, the locking component is a locking bolt 204. The connecting sleeve 2 has a threaded hole 203, and the locking bolt 204 is threadedly connected to the threaded hole 203. The locking bolt 204 is used to lock the limiting piston rod 3.

[0042] like Figure 4-5 As shown, the middle part of the limiting piston rod 3 is a connecting rod 301. The connecting rod 301 cooperates with the connecting rod cavity 202. One end of the connecting rod 301 located in the receiving cavity is threadedly connected to the piston head 302, and the other end is fixedly connected to the handle 303. Several scale rings 305 are equidistantly arranged on the outer surface of the connecting rod 301.

[0043] The graduated rings 305, which are equidistantly arranged on the outer surface of the connecting rod 301, can help the operator to accurately control the position of the piston head 302. By observing the graduated rings 305, the operator can accurately understand the insertion depth of the piston head 302 in the test tube, thereby more accurately adjusting the position of the packing in the receiving cavity.

[0044] like Figure 4-5 As shown, the size of the piston head 302 is adapted to the receiving cavity, and a sealing groove is provided on the outer surface of the piston head 302, in which a sealing ring 304 is provided.

[0045] like Figure 6 As shown, the filling funnel 4 includes: a funnel body 401 and a funnel neck 402. The funnel body 401 is conical, and the funnel neck 402 is tubular and connected to the end of the funnel body 401 with the smaller diameter.

[0046] The neck 402 is sleeved on the outside of the test tube body 1. The inner cavity of the neck 402 is provided with a mating groove 403 at one end adjacent to the bucket body 401. The mating groove 403 is used to engage the end of the test tube body 1.

[0047] like Figure 6 As shown, the two ends of the receiving cavity in the middle of the test tube body 1 are provided with transition chamfers 101, and the transition chamfers 101 cooperate with the mating groove 403.

[0048] In traditional funnel structures, the neck 402 is directly inserted into the receiving cavity of the test tube body 1, which reduces the diameter of the pipe through which the packing passes. Therefore, this application uses the matching groove 403 and the transition chamfer 101 of the test tube body 1 to make the neck 402 fit outside the test tube body 1, and the inner side of the matching groove 403 serves as the inner neck, thereby avoiding the packing funnel 4 from having too small a pipe diameter, which would affect the filling efficiency of the packing.

[0049] In one specific embodiment, the surfaces of the receiving cavity and the piston head 302 are provided with a high-temperature resistant and non-stick coating.

[0050] The high-temperature resistant and non-stick coating prevents the filler from adhering to the piston head 302, thus preventing discrepancies between the actual mass of the filler and the pre-measured mass when the limiting piston rod 3 is removed after filling.

[0051] Specific filling process: Place the connecting sleeve 2 on one end of the test tube body 1, and press the handle 3 to make the piston head 302 extend into the inner cavity of the test tube body 1. Observe the scale ring 305 on the outer surface of the connecting rod 301. After reaching the preset depth, tighten the locking bolt 204 to fix the connecting rod 301. Then, lift the test tube body 1 vertically, place the filling funnel 4 on the other end, and pour the pre-measured activated carbon to be desorbed into the filling funnel 4. After filling is completed, place the test tube body 1 horizontally on the heating position of the sintering device 5, and then remove the filling funnel 4 and the connecting sleeve 2 for subsequent heating desorption.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
