Description

Technical Field

[0001] The utility model relates to the technical field of sulfur determinators, and particularly relates to a sample feeding mechanism of a sulfur determinator. Background Art

[0002] For coal, sulfur is a harmful element. High-sulfur coal will cause great harm when used for combustion, gasification or coking. In order to effectively and economically utilize coal resources, it is necessary to understand the sulfur content in coal. There are usually three methods for testing the sulfur content in coal, namely the Eschka method (gravimetric method), the coulometric titration method, and the high-temperature combustion neutralization method. Among them, the coulometric titration method is the most widely used. The coulometric titration method is used to test the sulfur content in coal. Using iodine as the titrant, at a high temperature of 1150°C, the sulfur in the coal sample will be converted into SO2 and SO3 gases. All the gases are introduced into the electrolytic cell. SO2 reacts with water to form sulfurous acid, which oxidizes the electrolytic iodine to form sulfuric acid. The instrument uses a double platinum electrode to indicate the end point. According to the amount of electricity consumed during the electrolysis of iodine, the sulfur content in the coal can be calculated by Faraday's law, which is also the test principle of the sulfur determinator.

[0003] The Chinese utility model patent with the application number 202220292406.1 discloses an automatic sulfur determinator sample feeding mechanism. The above technical solution uses a rotary sample placing mechanism to place samples. The crucible is placed on the rotary chain of the rotary sample placing mechanism, and multiple samples can be placed at one time. When the crucible reaches the sample inlet, it can be pushed into the sample and sampled by a sample feeding rod driven by a reciprocating driving mechanism. The set control mechanism can directly drive the up and down movement of the sample feeding rod to complete the temporary combination and loosening with the crucible. The utility model can automatically complete the continuous sample feeding of multiple samples, greatly saving manpower.

[0004] However, in the actual use process, when the above technical solution hooks out the tested crucible and pushes a new crucible into the sample, it is difficult to ensure the stability of loading and unloading. The crucible is easy to get stuck during transportation, and it is easy to have jams, and it needs to be stopped for adjustment, thus affecting its normal use and further affecting its sample feeding efficiency. In addition, when feeding in the above way, the sample inside the crucible is easy to spill out, thus affecting the accuracy of sample detection.

[0005] Therefore, a sample feeding mechanism of a sulfur determinator is proposed. Utility Model Content

[0024] Such as Figures 1-3As shown in the figure, a sample feeding mechanism for a sulfur determination instrument includes a sulfur determination instrument body 1. A sample feeding frame 6 is slidably arranged on the sulfur determination instrument body 1. A bottom plate 2 is arranged at the bottom end of the sulfur determination instrument body 1. A conveying member 5 is arranged on the sulfur determination instrument body 1. The conveying member 5 includes a rotating belt 504. A plurality of uniformly arranged limiting frames 4 are arranged on the belt 504. A crucible groove 401 is formed on the limiting frame 4. A first clamping member 8 and a second clamping member 9 are arranged on one side of the sulfur determination instrument body 1. A position adjusting member 7 for driving the first clamping member 8 and the second clamping member 9 to move is arranged on the sulfur determination instrument body 1. The position adjusting member 7 includes a first mounting plate 701 arranged on one side of the sulfur determination instrument body 1. A first slide rail 702 is arranged at the bottom end of the first mounting plate 701. A first slider 705 is slidably arranged inside the first slide rail 702. An electric telescopic rod 706 is arranged at the bottom end of the first slider 705. The telescopic end of the electric telescopic rod 706 is connected to a second mounting plate 707. The first clamping member 8 includes a second slide rail 801 arranged at the bottom end of the second mounting plate 707 and two first clamping plates 805 slidably arranged on the second slide rail 801. The second clamping member 9 includes a third slide rail 901 arranged at the bottom end of the second mounting plate 707 and two second clamping plates 905 slidably arranged on the third slide rail 901. Specifically, a crucible containing a sample to be detected is placed on the limiting frame 4. Three sides of the crucible groove 401 are fixed, so it can play a good role in limiting the placed crucible. The arranged first clamping member 8 and second clamping member 9 can respectively clamp the crucible to be detected and the crucible after detection. After clamping, the arranged position adjusting member 7 can drive the positions of the two crucibles to be adjusted, transfer the crucible to be detected to the position of the sample feeding frame 6, and transfer the crucible after detection to the position of the collection box 3. Then, the first clamping member 8 and the second clamping member 9 cancel the limitation on the crucible to be detected and the crucible after detection, and the automatic feeding of the sample can be realized. At the same time, the sample after detection can be automatically collected. During the sample feeding process, the clamping stability can be ensured, so that the sample can be accurately moved to the corresponding position without jamming, thereby ensuring the feeding efficiency and avoiding the sample from spilling out and affecting the detection accuracy. During the continuous sample feeding process, the arranged conveying member 5 can drive the limiting frame 4 to be stably conveyed forward. The length of the limiting frame 4 closest to the sample feeding frame 6 from the sample feeding frame 6 is the same as the distance length from the sample feeding frame 6 to the collection box 3. At the same time, when the first clamping member 8 and the second clamping member 9 work, the distance between the samples clamped by them is the same as the spacing between the limiting frame 4 and the sample feeding frame 6 and the spacing between the sample feeding frame 6 and the collection box 3. The sample feeding frame 6 can automatically expand and contract, and can send out the detected sample outward, and convey the newly placed sample into the sulfur determination instrument body 1 for combustion detection. This is the prior art, so the driving structure thereof will not be elaborated here too much.

[0025] As Figure 1As shown, a collection box 3 is provided at the top of the bottom plate 2; specifically, the provided collection box 3 can collect the tested samples. The collection box 3 is made of heat-resistant material, which can prevent it from deforming under high temperature, and its outer surface has heat-insulating material, so that the staff will not be scalded when transferring the collection box 3.

[0026] As Figure 1 shown, two fixing plates 501 are provided at the top of the bottom plate 2. A first motor 502 is provided on one side of one of the fixing plates 501. One pulley 503 is rotatably provided on each of the two fixing plates 501. One of the pulleys 503 is connected to the main shaft end of the first motor 502. A belt 504 is sleeved between the two pulleys 503; specifically, when the first motor 502 works, it can drive the pulley 503 to rotate, and thus can drive the belt 504 to transmit and convey.

[0027] As Figure 2 shown, a second motor 703 is provided on one side of the first slide rail 702. The main shaft end of the second motor 703 is connected with a reciprocating lead screw 704. The first slider 705 is threadedly sleeved on the reciprocating lead screw 704; specifically, when the second motor 703 works, it can drive the reciprocating lead screw 704 to rotate, and the rotation of the reciprocating lead screw 704 can drive the first slider 705 to slide reciprocally, so that the positions of the subsequent first clamping member 8 and the second clamping member 9 can be adjusted reciprocally, which is convenient for driving the automatic loading and unloading of samples.

[0028] As Figure 3 shown, a third motor 802 is provided on one side of the second slide rail 801. The main shaft end of the third motor 802 is connected with a first bidirectional lead screw 803. Two second sliders 804 are slidably arranged inside the second slide rail 801. Both of the two second sliders 804 are threadedly sleeved on the first bidirectional lead screw 803. Two first clamping plates 805 are respectively provided at the bottom of one of the second sliders 804. Anti-slip pads 806 are respectively provided on the corresponding sides of the two first clamping plates 805; specifically, when the third motor 802 works, it can drive the first bidirectional lead screw 803 to rotate, and the rotation of the first bidirectional lead screw 803 can drive the two second sliders 804 to approach or move away from each other, so that the two first clamping plates 805 can approach or move away from each other, thereby realizing the clamping of the crucible containing the sample to be tested. The provided anti-slip pads 806 prevent the crucible from moving or falling, ensuring the stability of the clamping.

[0029] As Figure 3As shown in the figure, a fourth motor 902 is provided on one side of the third slide rail 901. The main shaft end of the fourth motor 902 is connected to a second bidirectional lead screw 903. Two third sliders 904 are slidably arranged inside the third slide rail 901. Both of the two third sliders 904 are threadedly sleeved on the second bidirectional lead screw 903. Two second clamping plates 905 are respectively arranged at the bottom end of one of the third sliders 904. One heat insulation pad 906 is respectively arranged on the corresponding side of the two second clamping plates 905. Specifically, when the fourth motor 902 works, it can drive the second bidirectional lead screw 903 to rotate. The rotation of the second bidirectional lead screw 903 can drive the two third sliders 904 to approach or move away from each other. Therefore, it can drive the two second clamping plates 905 to approach or move away from each other, so as to clamp the crucible containing the sample to be detected. The provided heat insulation pad 906 can prevent the high-temperature crucible from causing deformation of the second clamping plate 905 and affecting the clamping stability.

[0030] In summary: A crucible containing the sample to be detected is placed on the limit frame 4. Three sides of the crucible groove 401 are fixed. Therefore, it can play a good role in limiting the placed crucible. The provided first clamping member 8 and second clamping member 9 can respectively clamp the crucible to be detected and the crucible after the detection is completed. After clamping, the provided position adjustment member 7 can drive the positions of the two crucibles to be adjusted, transfer the crucible to be detected to the position of the sample feeding frame 6, and transfer the crucible after the detection is completed to the position of the collection box 3. Then, the first clamping member 8 and the second clamping member 9 cancel the limitation on the crucible to be detected and the crucible after the detection, and the automatic feeding of the sample can be realized. At the same time, the sample after the detection can also be automatically collected. During the sample feeding process, the clamping stability can be ensured, so that the sample can be accurately moved to the corresponding position without jamming, thereby ensuring the feeding efficiency and also avoiding the sample spilling out and affecting the detection accuracy.
