Description

Technical Field

[0001] The invention relates to the technical field of coal quality detection, in particular to an assay device for coal quality detection. Background Art

[0002] Coal is a solid combustible mineral that is gradually formed when ancient plants are buried underground and undergo complex biochemical and physicochemical changes.

[0003] Before using coal, it needs to be tested. Coal testing is a process of experimental analysis of coal samples to determine parameters such as physical properties, chemical composition and calorific value of coal. Common coal testing items include ash, volatile matter, fixed carbon, sulfur, moisture, ash melting point and calorific value. These test results can further help determine the quality, use and suitability of coal for industrial applications. When conducting ash analysis on coal, two methods are usually used: slow ash method and fast ash method. Among them, the slow ash method gives more accurate results. The operation steps are as follows: weigh a certain amount of coal sample, spread it evenly on an ash dish, and then put it into a muffle furnace. Open the furnace door and slowly raise the temperature to 500°C under natural ventilation. After keeping it for a period of time, this operation can gradually evaporate the moisture in the coal sample and decompose the organic matter in the coal sample. Then close the furnace door and make the temperature in the furnace at 815°C. After burning for a period of time, take out the ash dish, put it in a dryer to dry, weigh the ash dish, compare the weight, and then perform inspection burning to ensure that the quality does not change after burning.

[0004] When conducting ash content testing on coal, manual weighing and operation are usually adopted. The testing process is slow, the degree of automation is low, and it is easily affected by human factors, resulting in errors in the test results. Summary of the invention

A matching bevel gear 65 is provided on the base 1 between the drying unit 9 and the feeding unit 6, and the matching bevel gear 65 is meshed with the bevel gear 56. A material receiving assembly 76 is provided on the base 1 below the ash tray 4, and the material receiving assembly 76 is located between the drying unit 9 and the feeding unit 6.

[0054] Working principle of rotating mechanism 17: in the initial state, torsion spring three 54 is in a relaxed state. When passing through the matching bevel gear 65, the matching bevel gear 65 causes the bevel gear 56 to rotate. The matching bevel gear 65 is a partial bevel gear structure. At the same time, the matching bevel gear 65 is fixed on the base 1. The torsion spring three 54 is twisted, and the bevel gear 56 drives the rotating shaft two 53 to rotate. The rotating shaft two 53 drives the ash dish 4 to rotate, thereby realizing the unloading of coal samples. When the matching bevel gear 65 is no longer in contact with the bevel gear 56, the torsion spring three 54 drives the rotating shaft two 53 to rotate, thereby returning the ash dish 4 to the initial position.

[0055] Combined with Fig.11 , Attachment Fig.12 , Attachment Fig.13 , Attachment Fig.14 , Attachment Fig.15 , Attachment Fig.16 As shown, the material receiving assembly 76 includes a sliding hole 68 on the base 1 located on one side of the mating bevel gear 65, a sliding shell 69 is slidably provided in the sliding hole 68, a collecting box 70 is slidably provided in the sliding shell 69, and a spring 71 is provided between the sliding shell 69 and the inner wall of the sliding hole 68.

[0056] The working principle of the material receiving assembly 76 is as follows: by pulling the sliding shell 69 downwards and then pulling the collecting box 70 horizontally, the waste materials in the collecting box 70 are taken out.

[0057] In specific use, a certain amount of coal sample is placed in the storage cylinder 19, the power assembly 5 drives the rotating ring 2 to rotate, and the motion mechanism 15 on the connecting rod 3 drives the discharge mechanism 10 and the weighing mechanism 11 to move, so as to complete the discharge and weighing. When passing between the feeding unit 6 and the pretreatment unit 7, the ash dish 4 is reciprocated horizontally through the translation mechanism 16 to spread the coal sample evenly, and the moisture and organic matter are removed through the pretreatment unit 7. Then the ash dish 4 enters the heating unit 8, and the motion mechanism 15 on the rotating ring 2 makes the driving mechanism 13 move, driving the closed door 12 to rotate, realizing the closing of the closed door 12, and then heating the coal sample, and then entering the drying unit. Element 9, the driving mechanism 13 closes the sealed door 12, and the driving mechanism 13 drives the weighing mechanism 14 to weigh the ash dish 4. When passing between the feeding unit 6 and the pretreatment unit 7, the ash dish 4 is rotated back and forth by the rotating mechanism 17, and the coal sample in the ash dish 4 is poured into the collecting box 70 to complete the ash content test. When conducting the test, in order to determine the accuracy of the test, the ash is generally inspected and burned. The coal sample in the collecting box 70 is taken out and poured into the storage cylinder 19, and then tested again, skipping the pretreatment unit 7, and directly burning, and then drying and weighing are performed to ensure that there is no change in quality before and after burning, and no subsequent inspection burning is required.
