[0002] Coke is one of the important incoming fuels in steel plants, and its thermal reactivity and post-reaction strength data are important bases for guiding production and settlement. At present, for the samples of coke thermal reactivity and post-reaction strength, they are usually made by a SYD-C220 full-automatic coke sample preparation machine. During the sample preparation process, the coke inside the sample preparation machine will collide with each other, generating irregular movements, resulting in some coke being ejected from the feed inlet of the sample preparation machine, causing the lack of coke samples and poor representativeness of sample preparation; and a large amount of dust will also overflow from the feed inlet of the sample preparation machine, polluting the working environment and affecting the physical health of operators. Content of the Utility Model:
[0003] The purpose of the utility model is to provide a dust-proof and material-blocking structure for a coke sample preparation machine.
[0004] The purpose of the utility model is implemented by the following technical solution: A dust-proof and material-blocking structure for a coke sample preparation machine, which includes a clamping block, a locking component, and a cover plate covering the feed inlet of the sample preparation machine; the clamping block is fixed on the edge of the feed inlet of the sample preparation machine, one side of the cover plate is hinged on the side wall at the feed inlet of the sample preparation machine, and the other side of the cover plate is connected to the clamping block through the locking component; the locking component includes a fixing plate, a rotating shaft, and a safety pin. On the upper surface of the cover plate near the clamping block, two relatively arranged fixing plates are fixed. The rotating shaft is rotatably arranged between the two fixing plates. A threaded hole is opened in the middle of the rotating shaft. The rod part of the safety pin is provided with an external thread, and the rod part of the safety pin is inserted and screwed into the threaded hole of the rotating shaft. When the opening part of the safety pin is sleeved on the clamping block, the cover plate is locked on the sample preparation machine.
[0005] Preferably, on the outer side wall of the sample preparation machine where one side of the cover plate is hinged, a plurality of support components are fixedly arranged at intervals along the length direction of the cover plate. Each support component includes a connecting plate and a support rod, and each support rod is vertically fixed on the outer side wall of the sample preparation machine through the corresponding connecting plate.
[0006] Preferably, it further includes a support plate, a dust collection cover, a vacuum cleaner, and a corrugated pipe; support plates are respectively fixed on the outer walls on opposite sides of the sample preparation machine. The dust collection cover is covered above the cover plate, and the bottom end of the dust collection cover abuts against the support plate; the vacuum cleaner is installed near the sample preparation machine, and the inlet of the vacuum cleaner is connected to the outlet of the dust collection cover through the corrugated pipe.
[0007] Preferably, a dust concentration detector is installed on the outer side wall of the sample making machine. The dust concentration detector is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the power switch of the vacuum cleaner.
[0008] Preferably, a handle is fixed on the upper surface of the cover plate.
[0009] Advantages of the present utility model: First, the present utility model is provided with a clamping block, a locking assembly and a cover plate. One side of the cover plate is hinged on the side wall at the feeding port of the sample making machine. The feeding port of the sample making machine can be closed by the cover plate to prevent the coke in the sample making machine from colliding with each other and popping out from the feeding port, avoiding the loss of coke samples. The other side of the cover plate is connected to the clamping block at the feeding port of the sample making machine through the locking assembly. When the sample making machine is making samples, the cover plate can be locked on the sample making machine through the locking assembly, further preventing the coke from popping out from the feeding port and at the same time reducing the dust overflow.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
[0017] As Figures 1-3 shown, a dust-proof and material-blocking structure for a coke sample preparation machine includes a clamping block 1, a locking assembly 2, a cover plate 3, a support plate 4, a dust collection hood 5, a vacuum cleaner 6, a corrugated pipe 7, and a dust concentration detector 8; the clamping block 1 is fixed on the top edge of the feeding port of the sample preparation machine 9, the cover plate 3 is movably covered at the feeding port of the sample preparation machine 9, the feeding port of the sample preparation machine 9 is closed by the cover plate 3 to prevent the coke in the sample preparation machine 9 from colliding with each other and popping out from the feeding port, and avoid the lack of coke samples. Among them, a handle 10 is fixed in the middle of the upper surface of the cover plate 3 to facilitate opening and closing the cover plate 3. The rear side of the cover plate 3 is hinged to the side wall at the feeding port of the sample preparation machine 9 through a hinge, and the front side of the cover plate 3 is connected to the clamping block 1 through the locking assembly 2. When adding coke materials, the cover plate 3 is opened to add materials. When the sample preparation machine 9 is preparing samples, the cover plate 3 is locked on the sample preparation machine 9 through the locking assembly 2 to prevent coke from popping out from the feeding port and reduce dust overflow at the same time; the locking assembly 2 includes a fixing plate 2.1, a rotating shaft 2.2, and a safety pin 2.3. Two relatively arranged fixing plates 2.1 are fixed on the upper surface of the cover plate 3 near the clamping block 1. A rotating shaft 2.2 is rotatably arranged between the two fixing plates 2.1. A threaded hole is opened in the middle of the rotating shaft 2.2. The rod part of the safety pin 2.3 is provided with an external thread, and the rod part of the safety pin 2.3 passes through and is screwed into the threaded hole of the rotating shaft 2.2. Rotating the safety pin 2.3 can adjust the linear distance between the opening part of the safety pin 2.3 and the rotating shaft 2.2, so that when the opening part of the safety pin 2.3 is lowered, it just fits over the clamping block 1. When the opening part of the safety pin 2.3 fits over the clamping block 1, the cover plate 3 is locked on the sample preparation machine 9. Rotating the rotating shaft 2.2 can make the opening part of the safety pin 2.3 disengage from the clamping block 1, facilitating the opening of the cover plate 3;
[0018] On the outer wall of the sample preparation machine 9 on one side of the hinged cover plate 3, a number of support components 11 are fixedly arranged at intervals along the length direction of the cover plate 3. After the cover plate 3 is opened, it is supported by the support components 11, restricting the cover plate 3 from continuing to rotate around the hinge, avoiding damage to the hinge. Each support component 11 includes a connecting plate 11.1 and a support rod 11.2. Each support rod 11.2 is vertically fixed on the outer wall of the sample preparation machine 9 through the corresponding connecting plate 11.1, and the support rod 11.2 plays a supporting role for the cover plate 3.
[0019] On the outer walls on the left and right sides of the sample preparation machine 9, support plates 4 are respectively horizontally fixed. Above the cover plate 3, a dust collection hood 5 is provided, and the bottom end of the dust collection hood 5 abuts against the support plate 4. The dust collection hood 5 wraps and covers the cover plate 3 at the feed inlet of the sample preparation machine 9, which is beneficial for dust collection and avoids dust spillage. A dust collector 6 is installed near the sample preparation machine 9. The inlet of the dust collector 6 is connected to the outlet of the dust collection hood 5 through a corrugated pipe 7. The position of the dust collection hood 5 can be adjusted by the telescoping of the corrugated pipe 7, facilitating the removal of the dust collection hood 5 when adding materials. A dust concentration detector 8 is installed on the outer wall of the sample preparation machine 9. The dust concentration detector 8 is electrically connected to the input end of the controller 12, and the output end of the controller 12 is electrically connected to the power switch of the dust collector 6. Although the cover plate 3 closing the feed inlet can reduce dust spillage, there is still a small amount of dust spilling from the gap, affecting the surrounding environment. Therefore, the dust concentration near the feed inlet of the sample preparation machine 9 is monitored in real time by the dust concentration detector 8. When the dust concentration detector 8 detects that the dust concentration exceeds the maximum set value, the controller 12 controls the power switch of the dust collector 6 to be turned on, and the dust enters the dust collector 6 through the dust collection hood 5 and the corrugated pipe 7.
[0020] Working process: When sample preparation is required, the operator first closes the cover plate 3 at the feed inlet of the sample preparation machine 9 through the handle 10; secondly, turn and screw the safety pin 2.3 to adjust the linear distance between the opening of the safety pin 2.3 and the rotating shaft 2.2, and rotate the rotating shaft 2.2 so that the opening of the safety pin 2.3 just sleeves on the fixture block 1, locking the cover plate 3 on the sample preparation machine 9, and start the coke sample preparation machine 9 for sample preparation; then, stretch the length of the corrugated pipe 7 to make the dust collection hood 5 wrap and cover the cover plate 3 at the feed inlet of the sample preparation machine 9. When the dust concentration detector 8 detects that the dust concentration around the sample preparation machine 9 exceeds the maximum set value, the controller 12 controls the power switch of the dust collector 6 to be turned on, and the dust enters the dust collector 6 through the dust collection hood 5 and the corrugated pipe 7; finally, when coke materials need to be added, compress the length of the corrugated pipe 7 to move the dust collection hood 5 away from the feed inlet of the sample preparation machine 9, then rotate the rotating shaft 2.2 to make the opening of the safety pin 2.3 disengage from the fixture block 1, and the operator opens the cover plate 3 through the handle 10, making the cover plate 3 supported and fixed by the support rod 11.2, and adding coke materials through the feed inlet of the sample preparation machine 9.
[0021] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
