Description

Technical Field

[0001] The utility model belongs to the technical field of sampling of coal to be charged into the furnace, and particularly relates to a sampling device for coal to be charged into the furnace. Background Technique

[0002] Coal to be charged into the furnace is the coal containing total moisture that enters the coal bunker of the boiler house. If the moisture content of the coal to be charged into the furnace is too large, it can reduce the temperature of the vertical flue. If the temperature is too low, the coke shrinkage is not good and it is not mature. At this time, if pushing the coke, it is easy to cause difficulties in pushing the coke and even damage the furnace body. If we want the coke to mature on time, we have to increase the amount of return gas for combustion, which increases the heat consumption and the usage amount of the return gas. Therefore, before the coal to be charged into the furnace is used, it is necessary to sample and detect the coal to be charged into the furnace.

[0003] Chinese Patent Application No. 202123177032.3 discloses a portable sampling device for coal to be charged into the furnace, which includes a portable box, a sampling rack and a base.

[0023] Specifically, the sampling box fixing mechanism 7 includes a card slot 71, a fixing component 72, a clamping block 73 and a fixing hole 74. A clamping block 73 is arranged on the side of the sampling box 10, a card slot 71 corresponding to the clamping block 73 is opened on the inner wall of the sampling rack 3, a fixing hole 74 is opened on the side of the clamping block 73, and a fixing component 72 is arranged inside the side of the card slot 71.

[0024] By adopting the above technical solution, when fixing the sampling box 10, slide the clamping block 73 on the side of the sampling box 10 downward inside the card slot 71. At this time, the fixing of the sampling box 10 can be realized in cooperation with the fixing component 72 and the fixing hole 74.

[0025] Specifically, the fixing component 72 includes a fixing rod 721 and a spring 724. A spring 724 is arranged inside the side of the card slot 71, and the other end of the spring 724 is provided with a fixing rod 721.

[0026] By adopting the above technical solution, when fixing the sampling box 10, first press the fixing rod 721. The fixing rod 721 compresses the spring 724 and embeds into the inside of the sampling rack 3. When the fixing rod 721 is aligned with the fixing hole 74, the spring 724 rebounds, thereby driving the fixing rod 721 to insert into the inside of the fixing hole 74 to realize the fixing of the sampling box 10.

[0027] Specifically, the fixing component 72 further includes an adjusting block 722 and an adjusting slot 723. An adjusting block 722 is arranged on the side of the fixing rod 721, and an adjusting slot 723 corresponding to the adjusting block 722 is opened on the side of the sampling rack 3.

[0028] By adopting the above technical solution, when opening the sampling box 10, slide the adjusting block 722 inside the adjusting slot 723. The adjusting block 722 drives the fixing rod 721 to slide out from the inside of the fixing hole 74, thereby realizing the disassembly of the sampling box 10.

[0029] In the use of this embodiment, the sampling staff holds the handle 4 at the top of the sampling frame 3 by hand to drive the entire sampling frame 3 to move for sampling work. The sampling frame 3 is placed on the conveyor belt in operation, and the sampling surface faces the direction in which the coal being fed into the furnace is transported. Under the drive of the conveyor belt and its own gravity, the coal being fed into the furnace slides upward along the sampling surface. Most of the coal being fed into the furnace slides over the sampling surface and thus continues to be transported along with the conveyor belt after leaving the sampling frame 3. A small part of the coal being fed into the furnace leaks through the retaining net 11 on the sampling surface and falls into the sampling box 10 to complete the sampling work. When fixing the sampling box 10, first press the fixing rod 721. The fixing rod 721 compresses the spring 724 and inserts into the interior of the sampling frame 3. When the fixing rod 721 aligns with the fixing hole 74, the spring 724 rebounds, driving the fixing rod 721 to insert into the interior of the fixing hole 74 to fix the sampling box 10. When opening the sampling box 10, slide the adjusting block 722 inside the adjusting groove 723. The adjusting block 722 drives the fixing rod 721 to slide out of the interior of the fixing hole 74, thus realizing the disassembly of the sampling box 10.

[0030] Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 lies in that: the universal wheel retracting mechanism 2 includes a threaded rod 201, bevel gear two 202, bevel gear one 203, rotating rod 204, motor 207, lifting plate 208, universal wheel 209 and support block 210. A motor 207 is provided on the side of the base 1. The output end of the motor 207 is provided with a rotating rod 204. The other end of the rotating rod 204 is provided with a bevel gear one 203. A bevel gear two 202 is meshed and installed on the side of the bevel gear one 203. The threaded rod 201 is fixedly arranged through the interior of the bevel gear two 202. The lifting plate 208 is threadedly connected to the surface of the threaded rod 201. The lower end of the lifting plate 208 is provided with a support block 210. The lower end of the support block 210 is provided with a universal wheel 209.

[0032] By adopting the above technical solution, when the device needs to be moved, turn on the motor 207. The motor 207 drives the rotating rod 204 to rotate through the output end. The rotation of the rotating rod 204 drives the bevel gear one 203 to rotate. The rotation of the bevel gear one 203 drives the bevel gear two 202 to rotate. The rotation of the bevel gear two 202 drives the threaded rod 201 to rotate. The rotation of the threaded rod 201 drives the lifting plate 208 to descend. The descent of the lifting plate 208 drives the support block 210 and the universal wheel 209 to descend and supports the entire device to rise. Then the device can be driven to move by the universal wheel 209.

[0033] Specifically, the universal wheel retracting mechanism 2 further includes a limiting groove 205 and a limiting block 206. The side of the lifting plate 208 is provided with a limiting block 206. The inner wall of the base 1 is provided with a limiting groove 205 corresponding to the limiting block 206.

[0034] By adopting the above technical solution, when the lifting plate 208 moves up and down, it will drive the limiting block 206 to slide inside the limiting groove 205, thereby improving the stability of the lifting process of the lifting plate 208.

[0035] When this embodiment is in use, the sampling staff holds the handle 4 at the top of the sampling frame 3 by hand to drive the entire sampling frame 3 to move for sampling work. The sampling frame 3 is placed on the working conveyor belt, and the sampling surface faces the direction of the incoming coal being conveyed. Under the drive of the conveyor belt and its own gravity, the incoming coal slides up along the sampling surface. Most of the incoming coal slides over the sampling surface and thus continues to be conveyed with the conveyor belt after leaving the sampling frame 3. A small part of the incoming coal leaks through the retaining net 11 on the sampling surface and falls into the sampling box 10 to complete the sampling work. When fixing the sampling box 10, first press the fixing rod 721. The fixing rod 721 compresses the spring 724 and inserts into the interior of the sampling frame 3. When the fixing rod 721 aligns with the fixing hole 74, the spring 724 rebounds, thereby driving the fixing rod 721 to insert into the interior of the fixing hole 74 to achieve the fixation of the sampling box 10. When opening the sampling box 10, slide the adjusting block 722 inside the adjusting groove 723. The adjusting block 722 drives the fixing rod 721 to slide out of the interior of the fixing hole 74, thereby achieving the disassembly of the sampling box 10; when the lifting plate 208 moves up and down, it will drive the limiting block 206 to slide inside the limiting groove 205, thereby improving the stability of the lifting process of the lifting plate 208.

[0036] Working principle and usage process of the present utility model: When the present utility model is in use, the sampling staff holds the handle 4 at the top of the sampling frame 3 by hand to drive the entire sampling frame 3 to move for sampling work. Place the sampling frame 3 on the working conveyor belt, and make the sampling surface face the direction in which the coal to be fed into the furnace is transported. Under the drive of the conveyor belt and its own gravity, the coal to be fed into the furnace slides upward along the sampling surface. Most of the coal to be fed into the furnace slides over the sampling surface, thus separating from the sampling frame 3 and continuing to be transported along with the conveyor belt. A small part of the coal to be fed into the furnace leaks through the retaining net 11 on the sampling surface and falls into the sampling box 10 to complete the sampling work. When fixing the sampling box 10, first press the fixing rod 721. The fixing rod 721 compresses the spring 724 and inserts into the interior of the sampling frame 3. When the fixing rod 721 aligns with the fixing hole 74, the spring 724 rebounds, thus driving the fixing rod 721 to insert into the interior of the fixing hole 74 to achieve the fixation of the sampling box 10. When opening the sampling box 10, slide the adjusting block 722 inside the sliding adjustment groove 723. The adjusting block 722 drives the fixing rod 721 to slide out from the interior of the fixing hole 74, thus achieving the disassembly of the sampling box 10; The sampling staff holds the handle 4 at the top of the sampling frame 3 by hand to drive the entire sampling frame 3 to move for sampling work. Place the sampling frame 3 on the working conveyor belt, and make the sampling surface face the direction in which the coal to be fed into the furnace is transported. Under the drive of the conveyor belt and its own gravity, the coal to be fed into the furnace slides upward along the sampling surface. Most of the coal to be fed into the furnace slides over the sampling surface, thus separating from the sampling frame 3 and continuing to be transported along with the conveyor belt. A small part of the coal to be fed into the furnace leaks through the retaining net 11 on the sampling surface and falls into the sampling box 10 to complete the sampling work. When fixing the sampling box 10, first press the fixing rod 721. The fixing rod 721 compresses the spring 724 and inserts into the interior of the sampling frame 3. When the fixing rod 721 aligns with the fixing hole 74, the spring 724 rebounds, thus driving the fixing rod 721 to insert into the interior of the fixing hole 74 to achieve the fixation of the sampling box 10. When opening the sampling box 10, slide the adjusting block 722 inside the sliding adjustment groove 723. The adjusting block 722 drives the fixing rod 721 to slide out from the interior of the fixing hole 74, thus achieving the disassembly of the sampling box 10; When the lifting plate 208 moves up and down, it will drive the limiting block 206 to slide inside the limiting groove 205, thereby improving the stability of the lifting process of the lifting plate 208.
