Description

Technical Field

[0001] This utility model relates to the field of coal detection technology, and in particular to a high-precision instrument for coal detection. Background Technology

[0002] Sulfur is the most significant harmful component in coal samples. The sulfides contained in coal generate harmful gases after combustion and are released into the atmosphere with the flue gas, causing air and environmental pollution. Therefore, the detection of sulfur content in coal samples is a very important procedure for coal production, sales, use, and environmental protection departments.

[0003] Current coal sulfur content detectors require manual sampling. CN221883633U discloses a coal sulfur content detector that automatically delivers a ceramic boat containing coal to a heating tube for combustion and testing via a transport unit. However, this device can only test one type of coal sample at a time, and the time from heating to testing completion is long. When testing multiple groups of different coal samples, the entire testing cycle is very time-consuming and impractical. Therefore, this invention proposes a high-precision instrument for coal testing to solve the problems existing in the prior art. Utility Model Content

The limiting frame has an open structure on the side facing the feeding mechanism, which can facilitate pushing the material boat in and placing it in the limiting frame for heating.

[0018] according to Figures 1-5 As shown, this embodiment provides a high-precision instrument for coal testing, including a base plate 1, a heating mechanism, a feeding mechanism, a main controller 2, a sulfur analyzer 3, and a display screen 4. The heating mechanism includes a heating hood 5, a heating chamber 6, a lifting cylinder 7, a sealing base plate 8, a heating frame mechanism, and a heat insulation layer 9. The heating hood 5 is mounted on the base plate 1, and the heating hood 5 is divided into multiple heating chambers 6. The heating chambers are separated into multiple groups by partitions, which can be used to simultaneously heat and test the sulfur content of different types of coal. The base plate 1 below the heating hood 5 is connected to the heating frame mechanism by a lifting cylinder 7. The lifting cylinder 7 is equipped with a sealing base plate 8, which is sealed and adapted to the opening below the heating cover. A heating frame mechanism is symmetrically arranged on the sealing base plate 8. A heat insulation layer 9 is provided on the sealing base plate 8 and inside the heating chamber 6 to prevent the operator from being burned by heat conduction from the top of the heating cover and the sealing base plate, while also providing heat preservation and avoiding energy waste. A feeding mechanism is provided on the base plate 1 on the front side of the heating cover 5, and a main controller 2 is provided on the base plate 1 on the rear side of the heating cover 5. The main controller 2 is equipped with a sulfur analyzer 3 and a display screen 4 for sulfur measurement and data display.

[0019] The heating frame mechanism includes a support plate 10, a limiting frame 11, and an electric heating tube 12. The support plate 10 is symmetrically arranged on the sealed base plate 8. The support plate is suspended. The limiting frame 11 is provided on the support plate 10. The limiting frame 11 has an open structure on the side facing the feeding mechanism, which can facilitate the pushing of the material carrier boat into the limiting frame for heating. The electric heating tube 12 is embedded in the middle of the limiting frame 11 and the support plate 10 to heat the coal.

[0020] The heating cover 5 is symmetrically connected to the base plate 1 on both sides via side uprights 22. The heating cover is an overhead structure with a lifting cylinder and a sealing base plate underneath. A control panel 13 is provided on the front of the heating cover 5, which corresponds to the heating chambers one by one, so as to facilitate the adjustment of the heating parameters of different heating chambers to cope with different types of coal. A fan 14 is provided on the top of the heating cover 5. The fan 14 is connected to the internal pipe of the heating chamber 6 to control the amount of air injected to adjust the oxygen supply. The rear of the heating chamber 6 is connected to the sulfur analyzer 3 via a pipe, so that the heated sulfur-containing gas is sent into the sulfur analyzer for measurement.

[0021] The feeding mechanism includes a feeding platform 15, a hinged connecting plate 16, a fixed plate 17, a lifting cylinder 18, a pushing electric rod 19, and a pushing frame 20. The feeding platform 15 is provided on the base plate 1 on the front side of the heating cover 5. The hinged connecting plate 16 is provided on the side of the feeding platform 15 near the heating cover 5. The fixed plate 17 is provided on the base plate 1 on the front side of the feeding platform 15. The pushing electric rod 19 is symmetrically provided on the fixed plate 17 through the lifting cylinder 18. The pushing electric rod 19 has a pushing frame 20 at its telescopic end, which is used to push the material boat into the lowered limit frame.

[0022] The lower side of the pusher 20 is flush with the upper surface of the feeding platform 15. The front side of the pusher 20 is equipped with a feeding fork 21 corresponding to the heating chamber 6 and the heating frame mechanism. The hinge plate 16 is connected to the side of the feeding platform 15 by rotating shaft and torsion spring. The normal position of the hinge plate is horizontal. When the sealing base plate descends or rises, one end of the hinge plate will be pressed down or lifted to make it rotate to avoid the impact.

[0023] When using this high-precision coal testing instrument, the material carrier boat is placed on the feeding platform and aligned with the position of the feeding fork. Then, the sealing base plate is lowered by the lifting cylinder so that the support plate is flush with the hinged connecting plate. The push electric rod is started to drive the pusher frame to push the material carrier boat into the limit frame on the support plate. The feeding fork can position the material carrier boat to avoid deviation during the pushing process.

[0024] After being pushed, the pusher retracts, the sealing base plate rises and seals with the heating cover, and the material carrier enters its respective heating chamber. Then, the corresponding heating test parameters are set according to different types of coal through the control panel, the equipment is started to heat, and the sulfur-containing gas generated by heating enters the sulfur analyzer for measurement. The data is displayed intuitively on the screen.

[0025] Heat exchange tubes can also be installed on the inner wall of the heating cover. After heating, rapid cooling and heat exchange can be achieved, which can shorten the experimental cycle while avoiding energy waste and recycling. After cooling, the sealing base plate is lowered, and the feeding forks on the front side of the pusher frame are driven by the pusher rod to the sides of the material boat. The lifting cylinder lifts the material boat so that it is separated from the support plate. Finally, the pusher rod is retracted to retrieve the material boat.
