Description

Technical Field

[0001] The invention relates to the field of coal analysis, and in particular to a sample adding device for measuring coal ash content. Background Art

[0002] Coal ash measurement is an important part of coal quality analysis. It is used to determine the content of non-combustible minerals in coal. During the combustion process of coal, the organic matter in it will be oxidized and volatilized, while the inorganic minerals will remain. The ash content reflects the purity and thermal efficiency of coal, and is directly related to the pricing, performance and environmental impact of coal.

[0003] The existing method of adding samples for measuring coal ash content usually involves placing a sample pan on a weighing machine first, and then manually adding coal particles into the sample pan using a spoon. When the amount of coal particles in the sample pan is insufficient, the spoon needs to be repeatedly used to add more. When the amount of coal particles in the sample pan is excessive, a portion needs to be scooped out using a spoon. The operation is cumbersome and labor-intensive, which affects the efficiency of adding coal particles. In addition, during the feeding process, coal particles may splash out, which can easily cause harm to the operator and is quite inconvenient.

[0004] Therefore, it is necessary to design a sample adding device for measuring coal ash that can quantitatively feed coal particles while preventing coal particles from splashing, reduce coal particle sample loss, protect the health and safety of operators, save manpower, and improve coal particle adding efficiency. Summary of the invention

DETAILED DESCRIPTION

[0026] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] A sample adding device for measuring coal ash content, such as Figure 1 and Figure 2 As shown, it includes a support frame 1, a cylinder 2, a first storage bin 3, an electric push rod 4, a pushing rod 5 and a telescopic mechanism 6. The lower part of the support frame 1 is arc-shaped, and mounting holes are opened at the front and rear parts of the support frame 1 for easy installation. The upper part of the support frame 1 is connected to the cylinder 2, and the telescopic end of the cylinder 2 is connected to the first storage bin 3. The lower part of the first storage bin 3 is L-shaped for easy material unloading. The lower part of the first storage bin 3 is connected to the electric push rod 4, and the telescopic end of the electric push rod 4 is connected to the pushing rod 5. The pushing rod 5 is slidably connected to the first storage bin 3, and a telescopic mechanism 6 is provided between the pushing rod 5 and the first storage bin 3 to prevent coal particles from splashing.

[0028] like Figure 1 and Figure 3 As shown, the telescopic mechanism 6 includes a telescopic tube 61, a guide frame 62, a first guide sleeve 63, a second guide sleeve 64 and a first spring 65. The lower right part of the first storage bin 3 is slidably connected to the telescopic tube 61, and the lower part of the telescopic tube 61 is funnel-shaped for easy discharging. The lower middle part of the fixed end of the electric push rod 4 is connected to the first guide sleeve 63, and the guide frame 62 is slidably connected to the first guide sleeve 63. The guide frame 62 is folded, and the telescopic tube 61 is slidably matched with the guide frame 62. The lower left part of the push rod 5 is connected to the second guide sleeve 64, and the second guide sleeve 64 is slidably connected to the guide frame 62. A first spring 65 is connected between the second guide sleeve 64 and the guide frame 62.

[0029] When using the device, first fix the support frame 1 to the sample adding area for coal particle size measurement through the mounting hole, then pour the coal particles into the first storage bin 3, and then start the cylinder 2 to drive the first storage bin 3 to move to the right, so that the first storage bin 3 is aligned with the sample tray, and then start the electric push rod 4 to drive the push rod 5 to move to the right, so that the second guide sleeve 64 moves to the right, and the first spring 65 is stretched. When the second guide sleeve 64 is pulled to a certain distance, the tension of the first spring 65 drives the guide frame 62 to move quickly on the first guide sleeve 63, so that the telescopic tube 61 moves downward. The push rod 5 moves, thereby causing the coal particles to fall out of the telescopic tube 61, and quantitative feeding is carried out through the moving distance of the push rod 5, so that the coal particles can be quantitatively fed while preventing the coal particles from splashing, reducing the loss of coal particle samples, protecting the health and safety of operators, saving manpower, and improving the efficiency of coal particle addition. After that, the electric push rod 4 is started in reverse, driving the push rod 5 to move left, causing the second guide sleeve 64 to move left, and the first spring 65 is squeezed and restored to its original state, driving the guide frame 62 to move left, causing the telescopic tube 61 to move upward, and then the next sample tray is filled.

[0030] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes an adding mechanism 7, which includes a second material storage bin 71, a guide rod 72, a baffle 73 and a second spring 74. The second material storage bin 71 is connected to the fixed end of the cylinder 2, and the second material storage bin 71 is in contact with the first material storage bin 3. The lower left side of the second material storage bin 71 is connected to the guide rod 72, and a baffle 73 is slidably connected to the guide rod 72. The baffle 73 is in contact with the first material storage bin 3, and a second spring 74 is connected between the baffle 73 and the guide rod 72.

[0031] At this time, the second spring 74 is in a contracted state. When the adding mechanism 7 of the present device is used, the coal particles can be stored and added. When the coal particles need to be stored, the cylinder 2 can be started to drive the first storage bin 3 to move to the right, and the second spring 74 is restored, driving the baffle 73 to move to the right on the guide rod 72, and then the coal particles are poured into the second storage bin 71. When there are fewer coal particles in the first storage bin 3, the cylinder 2 can be started in the reverse direction to drive the first storage bin 3 to move to the left, so that the baffle 73 moves to the left, and the second spring 74 is squeezed and contracted, so that the coal particles in the second storage bin 71 fall into the first storage bin 3, so that the coal particles can be stored and added, which is convenient for adding to more sample trays, thereby improving the convenience of using the present device.

[0032] like Figure 1 and Figure 6 As shown, it also includes a grinding mechanism 8, which includes a motor 81, a grinding roller 82 and a blade 83. The motor 81 is connected to the right side of the lower part of the first storage bin 3, and the grinding roller 82 is connected to the output shaft of the motor 81. The grinding roller 82 is toothed to facilitate grinding and discharging. The grinding roller 82 is rotatably connected to the first storage bin 3. Two front and rear blades 83 are connected to the inner side of the middle part of the first storage bin 3, and the blades 83 are in contact with the grinding roller 82.

[0033] When the grinding mechanism 8 of the device is used, the coal particles can be ground. When the coal particles fall into the first storage bin 3, the motor 81 is started to drive the grinding roller 82 to rotate, and the coal particles are ground by the blade 83 and the grinding roller 82. The finer ground coal particles are discharged from the first storage bin 3 through the rotation of the grinding roller 82, so that the coal particles can be ground, which facilitates the full contact between oxygen and coal particles during the ashification process, accelerates the ashification rate, ensures that the coal particles are completely ashified, and improves the accuracy of the ash content measurement results.
