Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coal quality detection, in particular to a conveying mechanism and a coal quality detection device. Background Art
[0002] Coal quality testing is the process of analyzing and testing coal samples to evaluate their quality and performance. When testing the ash melting point, flammability and calorific value of coal, a muffle furnace is often needed to test and analyze it. Before sending the coal sample into the muffle furnace for combustion, the coal sample needs to be placed at the furnace mouth for preheating, and then the sample is moved a short distance closer to the furnace every two minutes of preheating. After five to ten minutes, the sample is pushed directly into the center of the furnace, and then the furnace door is closed for combustion testing. This can increase the surface temperature of the coal, thereby promoting the combustion of the coal, reducing the residence time of the coal in the furnace, and improving the combustion efficiency and the accuracy of the calorific value test.
[0003] However, the traditional coal preheating process requires the operator to place the coal on the ash pan rack, and then use a shovel to slowly and continuously push the ash pan rack into the furnace so that the coal can be fully preheated before entering the furnace, thereby ensuring the accuracy of the coal quality detection results. However, the process of pushing the ash pan rack with a shovel in the above process not only cannot control the pushing distance well, but also is prone to shaking during the pushing process, resulting in the coal sample being spilled, which will greatly affect the test results. Therefore, the above problem needs to be solved. Utility Model Content

Then, when the sliding component 103 is about to enter the furnace, the sliding component 103 will be blocked and cannot continue to move, and the pushing component 105 will continue to push the containing component 104 to separate from the sliding component 103, thereby sending the coal sample into the furnace for incineration detection.
[0035] Example 2
[0036] Reference Figures 2 to 6, which is the second embodiment of the utility model. Different from the previous embodiment, it also includes a propulsion component 100, including a muffle furnace 101, a furnace door rotatably connected to the muffle furnace 101, a support plate 102 rotatably connected to the muffle furnace 101, a sliding assembly 103 installed on the support plate 102, a containing assembly 104 installed on the sliding assembly 103, a pushing assembly 105 installed on the sliding assembly 103, a transmission assembly 106 installed on the support plate 102, and a blocking assembly 107 installed on the sliding assembly 103.
[0037] The sliding assembly 103 includes two groups of long grooves 103a opened on the support plate 102, a sliding frame 103b slidably connected to the long grooves 103a, a connecting plate 103c fixedly connected between the sliding frames 103b, a propulsion groove 103d opened on the sliding frame 103b, an abutment block 103e fixedly connected to the sliding frame 103b, and a blocking column 103f fixedly connected to the support plate 102.

[0039] Furthermore, the pushing assembly 105 includes a pushing rod 105a slidably connected to the sliding frame 103b, the pushing rod 105a abuts against the ash dish frame 104a, a fixed block 105b fixedly connected to the pushing rod 105a, the fixed block 105b prevents the pushing rod 105a from detaching from the sliding frame 103b when moving in the reverse direction, and a threaded rod 105c fixedly connected to the pushing rod 105a.
[0040] Furthermore, the transmission assembly 106 includes a through opening 106a opened on the support plate 102, a mounting frame 106b fixedly connected to the through opening 106a, a threaded sleeve 106c rotatably connected to the mounting frame 106b, the threaded sleeve 106c is threadedly connected to the threaded rod 105c, a mounting frame 106d fixedly connected to the bottom of the through opening 106a, a linkage column 106e rotatably connected to the mounting frame 106d, a chain 106f arranged between the threaded sleeve 106c and the linkage column 106e, and a motor 106g fixedly connected to the bottom of the support plate 102, the linkage column 106e is fixedly connected to the output shaft of the motor 106g, and when the motor 106g works and drives the output shaft to rotate, it will drive the threaded sleeve 106c to rotate, thereby driving the threaded rod 105c to move forward or backward, thereby driving the sliding frame 103b to move.
[0041] Furthermore, the blocking assembly 107 includes a rotating plate 107a arranged on the sliding frame 103b, a torsion spring 107b installed on the rotating plate 107a, and a rotating shaft 107c fixedly connected to the rotating plate 107a. The rotating plate 107a can rotate with the rotating plate 107a through the rotating shaft 107c, and under the action of the torsion spring 107b, the rotating plate 107a forms a right angle of ninety degrees with the sliding frame 103b when not affected by external force, and will automatically reset after being affected by external force, a connecting frame 107d fixedly connected to the rotating plate 107a, and a roller 107e rotatably connected to the connecting frame 107d.
[0042] During use, when it is necessary to test the coal sample, the coal sample can be placed on the ash dish box 104b first, and then the ash dish box 104b is placed on the ash dish rack 104a, and then the ash dish rack 104a is placed between the rotating plate 107a and the long groove 103a, the rotating plate 107a will block the ash dish rack 104a, at this time the sliding rack 103b will move with the movement of the ash dish rack 104a, and then the furnace door is opened to rotate the support plate 102 to the furnace mouth, and then the motor 106g can be started, and the threaded sleeve 106c will rotate under the drive of the motor 106g, and the rotating threaded sleeve 106c will drive the threaded rod 105c to move toward the furnace mouth, so that the threaded rod 105c will push the sliding rack 103b and the ash dish rack 104a to move toward the furnace mouth, gradually approaching the furnace mouth, this The process can fully preheat the coal sample, and the speed of movement of the ashtray rack 104a can be adjusted by adjusting the rotation speed of the motor 106g, so as to better control the advancement distance. When the abutment block 103e on the sliding rack 103b contacts the blocking rod, the blocking rod will prevent the sliding rack 103b from continuing to move forward. At this time, the motor 106g works normally and will continue to push the ashtray rack 104a forward. The rotating plate 107a will overcome the force of the torsion spring 107b and open outward under the thrust of the ashtray rack 104a, so that the ashtray rack 104a can pass through the rotating plate 107a, and then under the continued push of the push rod 105a, the ashtray rack 104a will separate from the sliding rack 103b and enter the furnace. At this time, the support plate 102 can be rotated to the side of the muffle furnace 101 to keep it away from the furnace mouth, and then the furnace door can be closed to start the incineration detection.

[0046] Furthermore, the limiting assembly 202 includes a limiting opening 202a opened on the sliding frame 103b, and a bolt 202b threadedly connected to the limiting opening 202a. When the sliding frame 201c is moved to a distance between the rotating plate 107a and the sliding frame 103b that is suitable for the length of the ash dish rack 104a, the bolt 202b can be passed through the limiting opening 202a to abut against the sliding frame 201c. Under the squeezing force of the bolt 202b, the sliding frame 201c will be fixed on the sliding frame 103b.
[0047] During use, the length distance between the rotating plate 107a and the sliding frame 103b can be adjusted by moving the sliding frame 201c, so as to be suitable for the installation and fixation of ash tray racks 104a of different lengths. After adjusting to the appropriate position, the bolt 202b can be passed through the limit opening 202a to abut against the sliding frame 201c.
