Description

Technical Field

[0001] This utility model relates to the field of tin smelting fuming process technology, specifically to an automatic and precise proportioning and conveying production line for pulverized coal in the tin smelting fuming process. Background Technology

[0002] The tin smelting fuming process is an important tin smelting method. In the tin smelting fuming process, the proportion of pulverized coal needs to be adjusted according to specific process requirements and raw material characteristics.

[0003] A search revealed that the announcement number is CN219494108U, entitled "A Feeding Device for a Fly Ash Fuel Incineration Boiler," which includes a fly ash conveying device, a fly ash mixing device, and a fuel conveying device. Research and analysis revealed that although this device solves the problem that fly ash particles are too fine and have a low specific gravity to burn in the dense phase region, prolongs the combustion time of fly ash in the furnace, increases the combustion share of fly ash, and improves boiler efficiency, it still has the following drawbacks to some extent.

[0004] For example, if the mixing of pulverized coal is not thorough enough during the mixing process, pulverized coal may still clump, making subsequent transportation difficult and making it impossible to control the amount of pulverized coal fed according to demand. In the process of processing, it is impossible to achieve a precise ratio, which affects the processing efficiency and quality of the product. In order to solve the above technical problems, we have designed an automatic precise ratio feeding production line for pulverized coal in the tin smelting fuming process. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model uses a motor to drive a pusher plate to push the coal powder upwards, which works in conjunction with a stirring plate to stir the coal powder. During the stirring process, the stirring plate rotates around a rotating rod, which engages with auxiliary teeth to allow the coal powder to pass through the gap between the two and be crushed. Torque is applied to the rotating rod through a torsion spring. After the motor reverses, the stirring plate applies a rebound force during the reverse rotation, which enables it to quickly engage with the auxiliary teeth to crush the coal powder, achieving a continuous crushing effect during the stirring process.

[0015] 2. This utility model uses a motor to drive a screw rod to rotate, so that the coal powder is evenly conveyed to the right and discharged into the receiving frame. After being weighed by a weighing sensor, the weight of the coal powder can be accurately observed. When the amount of coal powder in the receiving frame reaches the required ratio, the motor is turned off and the baffle is pulled out, so that the coal powder can be automatically discharged, achieving the effect of automatic and precise control of the ratio and facilitating material discharge.

Detailed Implementation

[0022] Please see Figures 1-5An automatic and precise proportioning and conveying production line for pulverized coal in a tin smelting fuming process includes a base plate 1. A conveying cylinder 2 is fixedly installed on the left side of the top of the base plate 1. A motor 4 is fixedly installed on the left side of the conveying cylinder 2. The output shaft of the motor 4 passes through the inner cavity of the conveying cylinder 2 and is fixedly installed with a screw rod 5. A discharge valve 6 is connected to the left side of the top of the conveying cylinder 2. By setting the discharge valve 6, the pulverized coal can be controlled to prevent it from falling down during the stirring and crushing process inside the hopper 7. After stirring, it can be opened to discharge into the conveying cylinder 2. The top of the discharge valve 6 is connected to the hopper 7. A proportioning component 8 is fixedly installed on the top of the hopper 7. The proportioning component 8 includes a motor 81. The output shaft of the motor 81 is fixedly connected to a rotating rod 82. A actuating plate 84 is fixedly sleeved on the bottom of the surface of the rotating rod 82. By setting the actuating plate 84, the pulverized coal can be... The coal powder at the bottom of the inner cavity of bucket 7 is continuously pushed upwards to achieve the effect of turning the coal powder and achieving a comprehensive mixing effect. A fixed frame 83 is fixedly connected to the top of the surface of rotating rod 82. Auxiliary teeth 86 are fixedly connected to both sides of the inner cavity of fixed frame 83. A rotating rod 87 is rotatably connected to the center of the bottom of the inner cavity of fixed frame 83 through a bearing. The top of rotating rod 87 extends through to the top of fixed frame 83. A stirring plate 85 is fixedly sleeved on the surface of rotating rod 87 and located in the inner cavity of fixed frame 83. A torsion spring 88 is sleeved on the top of the surface of rotating rod 87. A weighing component 3 is fixedly installed on the right side of the top of bottom plate 1. The weighing component 3 includes a weighing sensor 31. The weighing sensor 31 is fixedly installed on the right side of the top of bottom plate 1. A receiving frame 32 is fixedly installed on the top of weighing sensor 31. A baffle 33 is provided on the right side of receiving frame 32.

[0023] Please see Figure 1 and Figure 2 The surface of the screw rod 5 is in close contact with the inner wall of the conveying cylinder 2 and slides in contact with it. The bottom of the hopper 7 has a funnel-shaped structure, which allows the coal powder to be completely discharged from the inside of the hopper 7, thus avoiding the accumulation of coal powder.

[0024] Please see Figure 1 and Figure 2 A crossbeam is horizontally fixed between the left and right sides of the top of the hopper 7. The motor 81 is fixedly installed on the top of the crossbeam. By setting the crossbeam, the motor 81 can be stably installed. At the same time, it occupies little space on the top of the hopper 7 and will not affect the feeding.

[0025] Please see Figure 3 and Figure 4 Crushing teeth are fixedly connected to both sides of the stirring plate 85. The auxiliary teeth 86 are arranged in an alternating manner with the crushing teeth. By setting the crushing teeth and auxiliary teeth 86, the coal powder can be crushed by the crushing teeth driven by the stirring plate 85 after passing between the two.

[0026] Please see Figure 4A cover 89 is fitted onto the top of the surface of the rotating rod 87. The cover 89 is fixedly installed on the top of the fixed frame 83. The top and bottom of the torsion spring 88 are fixedly connected to the top of the rotating rod 87 and the top of the fixed frame 83, respectively. By setting the cover 89, the torsion spring 88 can be shielded to prevent coal dust from contacting the torsion spring 88 and affecting its normal function. This allows the torsion spring 88 to apply a rebound force to the rotating rod 87, so that the crushing teeth will not be stuck when passing through the auxiliary teeth 86.

[0027] Please see Figure 5 A handle is fixedly connected to the top of the baffle 33. By setting the handle, the baffle 33 can be easily pulled out from the inside of the slot 34, so that the coal powder inside the receiving frame 32 can be discharged along the inclined structure inside the receiving frame 32. A slot 34 is opened on the right side of the top of the receiving frame 32, and the baffle 33 is installed through the inside of the slot 34 and fits against its inner wall.

[0028] Please see Figure 5 The size of the baffle 33 is larger than the size of the receiving frame 32. The bottom of the inner cavity of the receiving frame 32 is set as a sloping structure, and the height of the left side is greater than that of the right side.

[0029] In use, coal powder is placed inside the conveying cylinder 2, and then the second motor 81 is started. Its output shaft drives the first rotating rod 82 to rotate, causing the bottom agitator plate 84 to push the coal powder upwards. Simultaneously, the stirring plate 85 rotates along with the first rotating rod 82 to stir the coal powder. During the stirring process, after the stirring plate 85 contacts the coal powder, it rotates around the second rotating rod 87, engaging with the auxiliary teeth 86 to allow the coal powder to pass through the gap between them and be pulverized. Torque is applied to the second rotating rod 87 by the torsion spring 88. After the second motor 81 is reversed, the stirring plate 85 rotates in reverse. During the process, a rebound force is applied, which allows it to quickly cooperate with the auxiliary tooth 86 to crush the coal powder. After the mixing and crushing are completed, the discharge valve 6 is opened and the motor 4 is started. The output shaft drives the screw rod 5 to rotate, which conveys the coal powder to the right in a spiral manner inside the conveying cylinder 2 until it is discharged from the right end discharge pipe into the receiving frame 32. Then, the weighing sensor 31 weighs the coal powder inside the receiving frame 32. When the required weight ratio is reached, the motor 4 is turned off, and then the baffle 33 is pulled upward from the slot 34, so that the coal powder can be discharged to the right along the slope of the receiving frame 32.

[0030] In summary, this tin smelting fuming process's automatic precise proportioning and conveying production line for pulverized coal, through the cooperation of the conveying cylinder 2, weighing component 3, motor 4, screw 5, discharge valve 6, hopper 7, and proportioning component 8, solves the problem that insufficient agitation of pulverized coal during the mixing process can lead to lumps, making subsequent conveying difficult and preventing precise control of the pulverized coal conveying amount according to demand, thus failing to achieve precise proportioning during processing.
