Description

Technical Field

[0001] The utility model relates to the technical field of sulfur determination instruments, in particular to an infrared sulfur determination instrument which is easy to repair. Background Art

[0002] The working principle of the infrared sulfur analyzer is to use infrared spectroscopy technology to irradiate the substance. The sulfur element in the substance will absorb specific infrared light, thereby generating a spectral signal. By comparing with the standard spectrum, the sulfur content in the substance can be determined. It is widely used in coal, petroleum, chemical industry, metallurgy, chemical analysis and other fields.

[0003] After searching, the Chinese patent publication number CN212379273U discloses an infrared sulfur meter, including a shell, an air inlet joint, an air outlet joint and a vertically arranged mounting tube, the air inlet joint and the air outlet joint are respectively inserted into the two ends of the mounting tube, the shell has a mounting seat at the bottom of the air outlet joint, the mounting seat has a mounting cavity, the mounting seat is provided with an elastic reset mechanism in the mounting cavity for driving the end of the air outlet joint to slide up and down, the air outlet joint has a first station and a second station after the elastic drive, when in the first station, the air outlet joint is inserted into the bottom of the mounting tube; when in the second station, the air outlet joint is detached from the bottom of the mounting tube and the distance between the air outlet joint and the air inlet joint is greater than the length of the mounting tube.

[0004] The above patent has the following shortcomings: it can reduce the probability of the rubber ring on the air inlet joint being misaligned when the installation pipe is removed, but when the coal sample is burned under high temperature conditions, various forms of sulfur in the coal will be burned and decomposed. These sulfur elements will combine with oxygen in the air to generate sulfur dioxide that is toxic and harmful to the environment, and the device cannot properly treat the generated harmful gases, which has certain limitations.

[0005] Therefore, an infrared sulfur analyzer which is easy to maintain is proposed. Utility Model Content

As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0031] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings. Embodiment 1:

[0032] like Figure 1 , 2 As shown, an infrared sulfur analyzer that is easy to maintain includes a collecting box 1, a belt conveyor 2 installed on the top of the collecting box 1, and a supporting platform 3 arranged on one side of the collecting box 1.

[0033] A bracket 4 is fixedly installed on the top of the supporting platform 3, and a detection component 5 is arranged on the top of the bracket 4. The detection component 5 is connected to a recovery bucket 7 through an air outlet pipe 6. The recovery bucket 7 is placed on the top of the supporting platform 3. A treatment liquid is injected into the recovery bucket 7. The treatment liquid is preferably ammonia water. The inner wall of the recovery bucket 7 is rotatably connected to a stirring blade 10 through a transmission shaft 9. The other end of the transmission shaft 9 is fixedly connected to a motor 8 through a coupling. The motor 8 is fixed to the top of the supporting platform 3 by bolts.

[0034] The starting motor 8 drives the transmission shaft 9 to drive the stirring blade 10 to rotate along the axis of the transmission shaft 9 as the rotation center. The detected gas will enter the recovery barrel 7 through the outlet pipe 6 and mix with the ammonia water. The stirring of the stirring blade 10 makes the mixing efficiency faster.

[0035] The device is provided with a recovery barrel 7 and a stirring blade 10, and a liquid capable of absorbing sulfur dioxide is injected into the recovery barrel 7, so that sulfur dioxide can be effectively treated and air pollution caused by direct discharge can be avoided. Under the stirring of the stirring blade 10, the sulfur dioxide gas is better dispersed in the ammonia solution, and the contact area between the two is increased, thereby accelerating the absorption process.

[0036] like Figure 3 As shown, the detection assembly 5 includes a fixing cylinder 11 and a fixing cylinder 2 16 fixed to the top of the bracket 4 by bolts, and one end of the air outlet pipe 6 away from the recovery barrel 7 is connected to the inner wall of the fixing cylinder 11.

[0037] The outer walls of the fixed cylinder 11 and the fixed cylinder 2 16 are fixedly installed with a limit ring 13 and are both threadedly connected with a threaded sleeve 15. The inner walls of the two threaded sleeves 15 are threadedly connected with the same drying cylinder 14. The drying cylinder 14 has a desiccant built in it, and two filter plates are detachably installed on the inner wall of the drying cylinder 14. The preferred desiccant in this embodiment is silica gel particles.

[0038] The inner wall of the fixed cylinder 11 is fixedly connected with an infrared detector 12 , and the fixed cylinder 2 16 is connected to an air pump 17 through a connecting pipe, and an air extraction pipe 18 is fixedly connected to the input end of the air pump 17 .

[0039] Start the air pump 17 to extract the gas generated after the combustion sample and transport it to the drying cylinder 14 through the connecting pipe and the fixed cylinder 16 for filtration, absorb the moisture in the gas, and ensure the concentration of sulfur dioxide; when the desiccant in the drying cylinder 14 needs to be replaced, the two threaded sleeves 15 can be rotated to the outer walls of the fixed cylinder 11 and the fixed cylinder 2 16 respectively. At this time, the threaded sleeve 15 no longer limits the drying cylinder 14, and the drying cylinder 14 can be removed from the fixed cylinder 11 and the fixed cylinder 2 16, one of the filter plates in the drying cylinder 14 is removed, the used desiccant is poured out, and then new desiccant is poured in and the filter plate is installed in the drying cylinder 14, and finally, after aligning the two ends of the drying cylinder 14 with the ends of the fixed cylinder 11 and the fixed cylinder 2 16, the threaded sleeve 15 is rotated so that the threaded sleeve 15 is located between the fixed cylinder 11 and the drying cylinder 14 and the drying cylinder 14 and the fixed cylinder 2 16, thereby connecting the fixed cylinder 11, the drying cylinder 14 and the fixed cylinder 2 16.

[0040] The device is provided with a drying cylinder 14 and a threaded sleeve 15, and the threaded sleeve 15 can be used to quickly disassemble or install the drying cylinder 14, so that the desiccant in the drying cylinder 14 can be replaced to ensure the concentration of sulfur dioxide. The rapid replacement of the drying cylinder 14 can save time and reduce the difficulty of operation, thereby improving the convenience of use of the device.

[0041] like Figure 4 , 5 As shown, a fixed cover 20 is fixedly installed on the top of the belt conveyor 2, and an igniter 19 is installed on the lower surface of the top of the fixed cover 20.

[0042] One end of the air extraction pipe 18 away from the air pump 17 is fixedly connected to the fixed cover 20 , and the inner wall of one side of the fixed cover 20 away from the air extraction pipe 18 is fixedly connected and communicated with the oxygen delivery pipe 22 and the methane delivery pipe 23 .

[0043] The sample is transported by a belt conveyor 2. When the sample reaches the bottom of the fixed cover 20, the igniter 19 is started to burn the sample, and oxygen and methane are transported into the fixed cover 20 by an oxygen delivery pipe 22 and a methane delivery pipe 23 to accelerate the combustion rate of the sample. The sulfur produced by the combustion reacts with oxygen to generate sulfur dioxide. The air pump 17 uses an exhaust pipe 18 to extract the generated sulfur dioxide for subsequent operation and processing.

[0044] In this embodiment: the belt conveyor 2 is used to convey the sample to be tested to the bottom of the fixed cover 20, and the igniter 19 is started to burn the coal at a high temperature. At the same time, the oxygen delivery pipe 22 and the methane delivery pipe 23 respectively deliver oxygen and methane to the fixed cover 20 to accelerate the combustion rate of the sample. Sulfur in various forms in the sample will be burned and decomposed, and combined with oxygen to form sulfur dioxide. The air pump 17 uses the exhaust pipe 18 to extract the sulfur dioxide and conveys it to the drying cylinder 14 through the connecting pipe and the fixed cylinder 16 for drying to ensure the sulfur dioxide concentration and improve the accuracy of the test results. The dried sulfur dioxide enters the fixed cylinder 11, and after being detected by the infrared detector 12, it enters the recovery barrel 7 through the outlet pipe 6, mixes with the ammonia water in the recovery barrel 7, and accelerates the mixing efficiency under the stirring of the stirring blade 10 to avoid direct emission of sulfur dioxide to pollute the air. Embodiment 2:

[0045] An infrared sulfur determination instrument that is easy to repair. This embodiment makes the following improvements on the basis of embodiment 1: Figure 4-6 As shown:

[0046] A door panel 21 is installed on the inner wall of one side of the collection box 1 through a hinge, and the inner wall of the bottom of the collection box 1 is inclined.

[0047] The top of the conveyor belt of the belt conveyor 2 is fixedly connected with a plurality of limit plates 24 , and sample boxes 25 are placed in the limit plates 24 .

[0048] In this embodiment: the testing personnel place the sample box 25 containing the sample in each set of limiting plates 24, and the sample is transported by the belt conveyor 2 to the bottom of the fixed cover 20 for high-temperature combustion. The burned waste is continued to be transported along with the sample box 25 and the belt conveyor 2. When the sample box 25 opens downward, it will fall into the collection box 1 due to the influence of gravity. Since the bottom of the collection box 1 is tilted, the sample box 25 will slide to the door panel 21. When all samples are tested, the door panel 21 is opened to take out all the sample boxes 25 for next use.

[0049] The device can continuously detect the sulfur content of multiple samples by arranging multiple groups of limit plates 24 and sample boxes 25, thereby improving the detection efficiency.

[0050] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
