Description

Technical Field

[0001] This utility model relates to the field of coal powder sampling technology, specifically a sampling device for coal powder processing. Background Technology

[0002] Powdered coal refers to coal with a particle size of less than 0.5 mm. Due to its high-efficiency combustion characteristics, it can meet the needs of continuous production and is therefore widely used in industries such as steel and power. The powdered coal processing flow includes key links such as grinding and grading, dust collection, packaging and conveying. Packaging and conveying refers to loading the collected powdered coal into ton bags using equipment such as screw conveyors and plate chain elevators, and then transporting it in batches through ton bags. In order to ensure that the powdered coal meets industry standards or the company's internal quality requirements, staff will sample and test the powdered coal inside the ton bags before they leave the factory, thereby avoiding losses caused by unqualified powdered coal.

[0003] When using existing coal powder processing sampling devices, workers typically insert the coal powder sampler directly into the ton bag to sample the coal powder. However, this sampling method is quite cumbersome, requiring workers to stand near the ton bag and forcefully rotate the coal powder sampler downwards. This not only places a heavy workload on the workers but also makes it difficult to control the sampling depth and weight, which is not conducive to the coal powder sampling and testing work.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 As shown, a sampling device for pulverized coal processing includes two supporting vertical plates 1 arranged in a mirror image, with a U-shaped frame 2 between the supporting vertical plates 1. It should be noted that, as... Figure 5As shown, two supporting vertical plates 1 are located on both sides of the ton bag conveyor belt and are fixedly connected to the ground. In actual use, after the previous ton bag reaches the U-shaped frame 2 and the coal ash sampling operation is completed, the next ton bag will be moved by the conveyor belt to the U-shaped frame 2, and this cycle is repeated to achieve sampling and testing of coal powder inside the ton bag. The bottom of the U-shaped frame 2 is equipped with a sampling component 6 that can replace manual labor to directly insert into the ton bag to complete the coal powder collection work. By setting the sampling component 6, the machine can replace manual labor to directly insert into the ton bag to complete the coal powder collection work. Compared with the common method of manually inserting the coal powder sampler into the coal powder, it reduces the difficulty of coal powder sampling to a certain extent and facilitates the coal powder sampling and testing work. The control panel 18 is fixed on one side of the supporting vertical plate 1, and the controller is installed inside the control panel 18. The controller inside the control panel 18 enables centralized management of other electronic devices, facilitating coordination of their operation. It should be noted that the controller can be a PLC controller or other electronically controlled devices with control and display functions. The controller is powered by an external power source and can distribute power. This invention does not alter the controller's power connection method; the specific connection method is based on existing technology, and its principle and process will not be detailed here. A lifting component 3 is provided on the outer side of the supporting vertical plate 1 for adjusting the height of the sampling component 6. The lifting component 3 is connected to the controller's terminal via a data cable. By setting the lifting component 3, the overall height of the U-shaped frame 2 and its bottom sampling component 6 can be quickly adjusted, allowing staff to adjust the sampling depth of the sampling component 6 in the ton bag according to actual needs.

[0017] The lifting assembly 3 includes a connecting horizontal plate 31 positioned above the U-shaped frame 2. The connecting horizontal plate 31 has an internal slot 32 to facilitate the passage of the U-shaped frame 2. The connecting horizontal plate 31 is connected to the supporting vertical plates 1 at both ends. Lifting cylinders 33 are fixedly installed at the bottom of both ends of the connecting horizontal plate 31. The top of the lifting cylinder 33 penetrates the connecting horizontal plate 31 and connects to the U-shaped frame 2. The lifting cylinder 33 is connected to the controller terminal via a data cable. Figure 1 , Figure 2 As shown, the U-shaped frame 2 can be vertically displaced in the strip groove 32 by using two sets of lifting cylinders 33, thereby enabling quick adjustment of the height position of the sampling component 6. This makes it convenient for staff to adjust the sampling depth of the sampling component 6 in the ton bag according to actual needs.

[0018] Both sides of the U-shaped frame 2 are fixedly connected to sliders 4. On the side of each of the two supporting vertical plates 1 that is close to each other, there is a groove 5 corresponding to the slider 4. The slider 4 is located inside the groove 5. Figure 1 , Figure 2As shown, by setting slider 4 and slide 5, the U-shaped frame 2 can remain smooth during vertical displacement, which helps to improve the working stability of sampling component 6 and lifting component 3.

[0019] The sampling assembly 6 includes a sampling cylinder 61 fixed to the bottom of the U-shaped frame 2. A drive shaft 62 is coaxially mounted inside the sampling cylinder 61, and a spiral auger 63 is fixedly installed on the outside of the drive shaft 62. A discharge pipe 64 is inclinedly mounted at the top of the sampling cylinder 61. An L-shaped plate 65 is fixedly connected to one side of the U-shaped frame 2. The top end of the discharge pipe 64 is connected to the sampling cylinder 61, and the bottom end of the discharge pipe 64 extends through to the outside of the L-shaped plate 65. Figure 3 , Figure 5 As shown, after the sampling cylinder 61 is directly inserted into the ton bag, the drive shaft 62 drives the spiral auger 63 to rotate, which can transport the coal ash inside the ton bag to the inside of the sampling cylinder 61. As the coal ash is continuously input, it will reach the discharge pipe 64 at the top of the sampling cylinder 61. Then the coal ash will fall into the pre-prepared collection container through the discharge pipe 64. In this way, the machine replaces the manual labor to directly insert into the ton bag to complete the coal powder collection work, which reduces the difficulty of coal powder sampling to a certain extent and is conducive to the coal powder sampling and testing work.

[0020] A drive motor 7 is fixedly installed at the bottom of the inner cavity of the U-shaped frame 2. The top end of the transmission shaft 62 passes through the U-shaped frame 2 and is connected to the output end of the drive motor 7. The drive motor 7 is connected to the controller terminal via a data cable. Figure 1 , Figure 3 As shown, the drive motor 7 can provide rotational force to the drive shaft 62, thereby driving the auger 63 located outside the drive shaft 62 to collect coal powder into the sampling cylinder 61, which facilitates the subsequent coal powder sampling work.

[0021] The L-shaped plate 65 has a material cylinder placement groove 14 inside, and a collection cylinder 15 is placed inside the material cylinder placement groove 14. Below the collection cylinder 15 is a material cylinder support plate 16. A strip rod 19 is fixedly connected to the top of one side of the material cylinder support plate 16. The top of the strip rod 19 is connected to the L-shaped plate 65. A weighing sensor 17 is installed on the top of the material cylinder support plate 16. The bottom of the collection cylinder 15 is in contact with the weighing sensor 17. The weighing sensor 17 is connected to the controller terminal via a data cable. Figure 2 , Figure 4 and Figure 5As shown, in actual use, the collection cylinder 15 is placed on top of the weighing sensor 17 and inside the cylinder placement groove 14. The drive motor 7 cooperates with the sampling component 6 to input coal powder into the collection cylinder 15 through the discharge pipe 64. At this time, the weighing sensor 17 can monitor the weight of the coal powder inside the collection cylinder 15, so that the staff can adjust the sampling weight of the sampling component 6 in the ton bag according to actual needs. It should be noted that after the coal ash sampling is completed, the lifting component 3 can be used to pull the sampling component 6 out of the ton bag as a whole. Then the drive motor 7 reverses so that the remaining coal ash inside the sampling cylinder 61 falls into the ton bag, thus completing the coal ash sampling operation.

[0022] Two symmetrical recessed cavities 8 are formed inside the L-shaped plate 65. Moving blocks 9 are slidably connected inside each recessed cavity 8. Clamping blocks 10 are fixedly connected to the sides of the two moving blocks 9 that are close to each other, and springs 13 are fixedly connected to the sides of the two moving blocks 9 that are far apart from each other. One end of the spring 13 is connected to the inner wall of the recessed cavity 8. Limiting grooves 12 are formed on both sides of each moving block 9. Limiting blocks 11 are provided inside the limiting grooves 12, and one side of the limiting block 11 is connected to the inner wall of the recessed cavity 8. Figure 1 , Figure 3 and Figure 4 As shown, the spring 13 can drive the clamping block 10 to position and fix the collection cylinder 15 from both sides, thereby preventing the collection cylinder 15 from shifting or tilting during coal ash sampling. At the same time, the setting of the limiting groove 12 and the limiting block 11 can prevent the clamping block 10 from completely dislodging from the relief cavity 8, thus improving the clamping stability of the collection cylinder 15. It should also be noted that both sides of the clamping block 10 are adapted to the curvature of the outer wall of the collection cylinder 15, which facilitates the insertion and removal of the collection cylinder 15.

[0023] Working principle: First, the ton bag is moved by the conveyor belt to the bottom of the U-shaped frame 2. Then, the height of the U-shaped frame 2 and the sampling component 6 at its bottom are quickly adjusted by the lifting component 3. This allows the staff to adjust the sampling depth of the sampling component 6 in the ton bag according to actual needs. Then, the sampling component 6, in conjunction with the drive motor 7, can use the machine to replace manual labor to directly insert into the ton bag to complete the coal powder collection. The spiral auger 63 will collect the coal powder into the sampling cylinder 61. Then, the coal powder falls into the pre-prepared collection cylinder 15 through the discharge pipe 64. Compared with the common method of manually inserting the coal powder sampler into the coal powder, this method reduces the difficulty of coal powder sampling to a certain extent and facilitates the coal powder sampling and testing work. At the same time, the moving block 9 and clamping block 10 inside the relief cavity 8 can prevent the collection cylinder 15 from shifting or tilting during the coal ash sampling process, and facilitate the insertion and removal of the collection cylinder 15.
