Description

Technical Field

[0001] This utility model belongs to the field of activated carbon desorption technology, and specifically relates to a sintering device for 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, to facilitate the filling of activated carbon, most activated carbon test tubes are placed vertically, with the activated carbon accumulating at the bottom of the tube after filling. Hot airflow or an external heating ring is then used to heat the activated carbon in the test tube. However, this arrangement, with the activated carbon accumulating at the bottom, easily leads to uneven heating, affecting the accuracy of the activated carbon desorption test. Therefore, a new test tube filling method is adopted, where the activated carbon to be desorbed is filled in the middle of the test tube, and then heated for desorption while keeping the test tube horizontal.

[0004] However, existing heating devices are not convenient for uniformly heating and desorbing test tubes in a horizontal state. Therefore, this application provides a sintering device for stainless steel chloride test tubes, which facilitates heating and desorbing test tubes with activated carbon located in the middle of the inner cavity, and ensures the uniformity of heating of the test tubes.

[0013] The number of air inlet pipes and return pipes corresponds to the number of heating tanks, and each end is provided with a connector for engaging with the end of the test tube body.

[0014] Furthermore, each intake pipe and return pipe is connected to a regulating valve, and the chassis is equipped with an adjusting knob for adjusting the regulating valve.

[0039] 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.

[0040] like Figure 1-4 As shown, a sintering apparatus for a stainless steel chloride test tube includes: a housing 2, a lower heating assembly 3 is provided on the upper part of the housing 2, and a tilting heating assembly 4 is provided on the upper part of the lower heating assembly 3, wherein the tilting heating assembly 4 is rotatably connected to the housing 2.

[0041] The lower heating assembly 3 includes: a fixed housing 301 fixedly connected to the chassis 2, an insulation layer 302 disposed inside the fixed housing 301, a heating plate 303 disposed in the middle of the insulation layer 302, a plurality of semi-circular heating grooves 304 arranged parallel and equidistantly on the heating plate 303, and snap-fit ​​grooves 305 corresponding to the heating grooves 304 opened on the fixed housing 301 and the insulation layer 302;

[0042] The flip heating assembly 4 includes a flip cover 401 rotatably connected to the chassis 2. The lower surface of the flip cover 401 is provided with a heat insulation layer 302 and a heating plate 303, and is symmetrically arranged with the heat insulation layer 302 and the heating plate 303 in the fixed housing 301. A corresponding snap-fit ​​groove 305 is opened on the flip cover 401, and the test tube body 1 is disposed in the snap-fit ​​groove 305.

[0043] Both the lower heating component 3 and the flip heating component 4 are equipped with heating plates 303, which are symmetrically arranged. The test tube body 1 is placed in the corresponding snap-fit ​​grooves 305 on the upper and lower sides. The heating plates 303 on both sides can heat the test tube at the same time, making the test tube more evenly heated during the heating process. Compared with single-sided heating, this double-sided heating method can effectively avoid local overheating or undercooling of the test tube due to uneven heating, and ensure the desorption effect of activated carbon in the test tube.

[0044] like Figure 1-2 As shown, the chassis 2 is equipped with a gas supply component for supplying inert gas to the test tube body 1 and a control component for adjusting the temperature of the heating plate 303.

[0045] like Figure 1 As shown, the air supply assembly includes: an air inlet 9, an air outlet 10, several air inlet pipes 6, and several return pipes 7;

[0046] The air inlet 9 and air outlet 10 are located on one side of the chassis 2. The air inlet 9 is connected to several air inlet pipes 6 through air pipes, and the air outlet 10 is connected to several return pipes 7 through air pipes. The air pipes are located inside the chassis 2.

[0047] The number of air inlet pipes 6 and return pipes 7 corresponds to the number of heating tanks 304, and each end is provided with a connector 8, which is used to cooperate with the end of the test tube body 1.

[0048] Providing inert gas to the test tube body 1 during the heating desorption process is crucial to prevent the desorbed gas from reacting with air and to facilitate subsequent measurements. By introducing inert gas into the test tube through the gas supply component, air inside the tube can be effectively eliminated, creating an oxygen-free or low-oxygen environment for the heating desorption of activated carbon, thereby ensuring the accuracy of subsequent measurements.

[0049] like Figure 1-2 As shown, each air inlet pipe 6 and return pipe 7 is connected to a regulating valve, and the casing 2 is equipped with an adjusting knob 11 for adjusting the regulating valve. This allows operators to easily turn on the air supply components and adjust the gas flow rate according to actual needs, and can be flexibly adjusted according to the actual quantity used.

[0050] like Figure 2 As shown, the control component includes a control box 12 located on the rear side of the chassis 2, and the control box 12 is equipped with a display screen 13 and an operation panel 14.

[0051] like Figure 6As shown, several centering components 15 are respectively provided on both sides of the fixed housing 301 and the flip cover 401. The centering components 15 are used to clamp the test tube body 1, so that the test tube body 1 is located in the middle of the snap-fit ​​groove 305. Preferably, the diameter of the test tube body 1 is adapted to the snap-fit ​​groove 305 and is smaller than the diameter of the heating groove 304. In this way, when heating, the test tube body 1 is just snapped into the snap-fit ​​groove 305, and the middle part does not directly contact the heating groove 304, thereby further improving the uniformity of heating of the test tube body 1.

[0052] However, when the diameter of the test tube body 1 is smaller than the snap-fit ​​groove 305, the central axis of the test tube body 1 does not correspond to the central axis of the snap-fit ​​groove 305, which can easily lead to uneven heating of the test tube body 1. Therefore, the centering component 15 is set to adjust the position of the test tube body 1.

[0053] like Figure 6-7 As shown, the centering component 15 includes: a mounting plate 1501 fixedly connected to the fixed housing 301 or the flip cover 401; a pair of sliding grooves 1502 are provided on the mounting plate 1501; a V-groove slider 1503 is slidably connected to the sliding grooves 1502; a V-groove slider 1503 has a V-shaped groove on the side adjacent to the test tube body 1 for engaging the test tube body 1; a locking bolt 1505 is provided on the V-groove slider 1503; and scale lines 1506 are provided on the fixed housing 301 and the flip cover 401.

[0054] By adjusting the upper and lower V-groove sliders 1503, the central axis of the test tube body 1 is aligned with the central axis of the snap-fit ​​groove 305. Then, the locking bolts 1505 are tightened to fix the V-groove sliders 1503. The scale line 1506 allows the operator to observe whether the positions of the two V-groove sliders 1503 are symmetrical, thereby determining whether the central axis of the test tube body 1 is aligned with the central axis of the snap-fit ​​groove 305.

[0055] like Figure 7 As shown, a return spring 1504 is provided inside the slide groove 1502. The return spring 1504 pushes out the V-groove slider 1503, making it convenient for operators to make adjustments.

[0056] like Figure 4-5 As shown, a rotating seat 5 is fixedly connected to the rear side of the chassis 2, and a rotating shaft hole 402 is provided on the rear side of the flip cover 401, and a handle 403 is provided on the front side. The flip cover 401 is rotatably connected to the rotating seat 5 through the rotating shaft hole 402.

[0057] A limiting plate 501 is provided on the side of the rotating base 5 away from the flip cover 401. The limiting plate 501 is located on the side of the rotating base 5 away from the flip cover 401. When the flip cover 401 is flipped to a certain angle, it will abut against the limiting plate 501, effectively limiting the flip angle of the flip cover 401 and preventing it from over-flipping. Over-flipping may cause the flip cover 401 to collide with the chassis 2 or other components, causing damage to the components and potentially affecting the safety of the operator. The limiting plate 501 ensures that the flip cover flips within a safe angle range, improving the reliability and safety of the device.

[0058] In the specific experimental procedure, the operator fills the activated carbon to be desorbed into the test tube body 1, places the test tube body 1 horizontally in the clamping groove 305, and ensures that the middle of the test tube body 1 corresponds to the middle of the heating tank 304. Then, the inlet pipe 6 and the return pipe 7 are connected to the two ends of the test tube body 1 through the connector 8, respectively. The air inlet 9 on the chassis 2 is connected to the external inert gas supply device, and the air outlet 10 is connected to the recovery box. The corresponding adjustment knob is turned on to fill the test tube body 1 with inert gas. Then, the flip heating component 4 is covered, and the heating plate 303 is started to heat the test tube body 1. The heating time, temperature, gas type and flow rate can be flexibly selected according to the specific experiment.

[0059] 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.
