Description

Technical Field

[0001] This utility model relates to the technical field of coal sample testing, and in particular to a device for measuring the fluidity of coal samples. Background Technology

[0002] The fluidity of a coal sample refers to its ability to flow when it softens and melts to form a plastic body during heating.

[0018] Please see Figures 1 to 5This utility model discloses a device for measuring the flowability of coal samples, comprising a detection chamber 100, a mixing chamber 200, a heating chamber 300, a lifting assembly 400, and a pushing assembly 500. A rotating rod 110 is rotatably mounted inside the detection chamber 100, and a speed sensor 111 is mounted on the rotating rod 110. A driven gear 112 is mounted on the top of the rotating rod 110. A receiving processor 120 is mounted on the outer side of the detection chamber 100. The mixing chamber 200 is located on the side of the detection chamber 100. The heating box 300 is disposed on the side of the mixing box 200. A gate 310 is slidably disposed inside the heating box. The lifting assembly 400 is connected to the gate 310. The pushing assembly 500 is disposed on the side of the heating box 300. A connecting pipe 600 is inclinedly disposed between the heating box 300 and the mixing box 200. A feeding port 320 and a feeding valve 330 are disposed on the top of the heating box 300. Furthermore, when a user needs to measure the flowability of a coal sample using the coal sample flowability measuring device of this utility model, firstly, the user opens the feeding valve 330 and adds the coal sample into the heating chamber 300 through the feeding port 320. After feeding is complete, the user closes the feeding valve 330, and the heating chamber 300 operates to heat and melt the coal sample to form a plastic body. Then, the lifting component 400 operates to lift the gate 310 upwards. Afterwards, the pushing component 500 operates to push the heated coal sample into the connecting pipe 600, and then it flows into the mixing tank 200. Secondly... The drive motor 230 drives the stirring roller 210 to rotate with a fixed power, and at the same time drives the drive gear 220 to rotate. The drive gear 220 drives the connecting gear 630 to rotate, and the connecting gear 630 drives the driven gear 112 to rotate, which in turn drives the rotating rod 110 to rotate. The rotation speed of the rotating rod 110 is detected by the speed sensor 111 and the data is transmitted to the receiving processor 120. The user can obtain the rotation speed of the rotating rod 110 through the data from the receiving processor 120. When the rotation speed is large, it indicates that the coal sample has strong fluidity, and vice versa.

[0019] In this embodiment, the heating box 300 is provided with a feeding port 320 and a feeding valve 330 at its top. The lifting assembly 400 includes a lifting bracket 410, a moving block 420, a connecting shaft 430, a first drive motor 440, and a lead screw 450. The lifting bracket 410 is disposed on the heating box 300. The lead screw 450 is rotatably disposed inside the lifting bracket 410. The first drive motor 440 is disposed above the lifting bracket 410. The lead screw 450 is connected to the output end of the first drive motor 440. The moving block 420 is threadedly connected to the lead screw 450. The moving block 420 is slidably connected to the inner wall of the lifting bracket 410. One end of the connecting shaft 430 is connected to the moving block 420, and the other end of the connecting shaft 430 is connected to the gate 310. The user opens the feeding valve 330 and adds the coal sample into the heating box 300 through the feeding port 320. After feeding is completed, the feeding valve 330 is closed, and the heating box 300 heats the coal sample to a plastic state. Then, the first drive motor 440 is started. The first drive motor 440 rotates forward, driving the lead screw 450 to rotate clockwise. The clockwise rotation of the lead screw 450 drives the moving block 420 to move upward. The moving block 420 drives the connecting shaft 430 to move upward. The connecting shaft 430 drives the gate 310 to move upward. When the first drive motor 440 rotates in reverse, the lifting assembly 400 drives the gate 310 to move downward. In addition, the lifting bracket 410 serves to install the lead screw 450. Both the connecting shaft 430 and the gate 310 are made of heat-resistant material.

[0020] In this embodiment, the pushing assembly 500 includes a cylinder 510, a push shaft 520, and a push plate 530. The cylinder 510 is disposed on the side of the heating box 300, the push plate 530 is disposed inside the heating box 300, the push shaft 520 passes through the heating box 300, one end of the push shaft 520 is connected to the output end of the cylinder 510, and the other end of the push shaft 520 is connected to the push plate 530. When the lifting component 400 moves the gate 310 upward, the pushing component 500 works, the cylinder 510 pushes the push shaft 520 forward, the push shaft 520 pushes the push plate 530 forward, and the push plate 530 pushes the heated coal sample into the connecting pipe 600. Since the connecting pipe 600 is inclined, the coal sample can slide down along the connecting pipe 600. In addition, both the push shaft 520 and the push plate 530 are made of heat-resistant material.

[0021] In this embodiment, a stirring roller 210 is rotatably arranged inside the stirring tank 200, a drive gear 220 is provided on the top of the stirring roller 210, and a second drive motor 230 is provided at the bottom of the stirring tank 200. The output end of the second drive motor 230 is connected to the stirring roller 210. The heated coal sample slides into the mixing tank 200 through the connecting pipe 600. The second drive motor 230 is started, which drives the mixing roller 210 and the drive gear 220 to rotate with a constant power. When the coal sample has good fluidity, the resistance to the mixing roller 210 is small, and the mixing roller 210 and the drive gear 220 can rotate at a higher speed. Conversely, the mixing roller 210 and the drive gear 220 rotate at a slower speed.

[0022] In this embodiment, an mounting plate 610 is provided between the mixing tank 200 and the detection tank 100. A rotating support frame 620 is provided on the mounting plate 610. A connecting gear 630 is rotatably provided on the rotating support frame 620. The connecting gear 630 and the driving gear 220 are meshed with the driven gear 112. A rotating rod 110 is rotatably provided inside the detection tank 100. A speed sensor 111 is provided on the rotating rod 110. A driven gear 112 is provided on the top of the rotating rod 110. A receiving processor 120 is provided on the outer side of the detection tank 100. The speed sensor 111 and the receiving processor 120 are electrically connected. The drive gear 220 rotates, driving the connecting gear 630 to rotate. The connecting gear 630 drives the driven gear 112 to rotate, and the driven gear 112 drives the rotating rod 110 to rotate. The speed sensor 111 detects the rotation speed of the rotating rod 110 and transmits the data to the receiving processor 120. The user obtains the rotation speed data of the rotating rod 110 through the receiving processor 120. When the drive gear 220 rotates faster, it drives the connecting gear 630 and the driven gear 112 to rotate at a faster speed. At this time, the rotation speed of the rotating rod 110 is faster, and the user can know that the coal sample has good fluidity. Conversely, the coal sample has poor fluidity. In addition, the rotating support frame 620 plays a role in stabilizing the rotation stability of the connecting gear 630. The mounting plate 610 provides the installation position for the rotating support frame 620. This device for determining the flowability of coal samples includes a detection chamber 100, a mixing chamber 200, a heating chamber 300, a lifting assembly 400, and a pushing assembly 500. A rotating rod 110 is rotatably mounted inside the detection chamber 100, and a speed sensor 111 is mounted on the rotating rod 110. A driven gear 112 is mounted on the top of the rotating rod 110. A receiving processor 120 is mounted on the outer side of the detection chamber 100. The mixing chamber 200 is located on the side of the detection chamber 100. The heating chamber 300 is... On the side of the mixing tank 200, a gate 310 is provided inside the heating tank 300. The gate 310 is slidably connected to the inner wall of the heating tank 300. The lifting assembly 400 is connected to the gate 310. The pushing assembly 500 is provided on the side of the heating tank 300. The coal sample flowability measuring device of this utility model links the various processes of coal sample testing through the cooperation of various structures, which improves the testing efficiency and avoids the impact of cumbersome processes on the coal sample testing effect.
