Among them, the steel ball in the ball mill escapes and directly falls into the pneumatic conveying bin pump with the material, the escaped steel ball of the ball mill is conveyed to the subsequent mixed acid machine and acidification kiln with the material, which causes damage to the subsequent mixed acid machine and acidification kiln. At the same time, the escaped steel ball of the ball mill has relatively large power required for material conveying and is conveyed slowly, which easily causes blockage of the conveying pipe due to the blocking of the material in the conveying pipe. SUMMARY

[0003] In order to solve the above problems, the utility model provides a material separation device, which effectively avoids the damage of the mixed acid machine caused by the escaped steel ball of the ball mill falling into the bin and entering the mixed acid machine, and prevents the blockage of the conveying pipe.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] The utility model discloses a material separation device, including the ball mill, conveying pipe and bin, the ball mill with the bin is passed through the conveying pipe intercommunication, the ball mill with the bin between being provided with the dust collection bin, the dust collection bin is provided with the dust collection fan, the ball mill, the dust collection bin with the bin passes through the conveying pipe and is connected in proper order, the conveying pipe's feeding end between the ball mill and the dust collection bin is located below its discharge end, the conveying pipe is close to the ball mill one end and is provided with the discharge port, the discharge port is provided with the discharge door.

[0006] Further, the conveying pipe is a Z-shaped conveying pipe, the Z-shaped conveying pipe includes a feeding section, a connecting section and a discharge section, and the discharge port is arranged in the feeding section.

[0008] Further, the discharge door is provided with a sealing ring.

[0009] Further, the discharge end of the dust collection bin is provided with a discharge valve, and the discharge end of the discharge valve is communicated with the bin through the conveying pipe.

[0010] The beneficial effects of this utility model are as follows: The material separation device of this application includes a dust collection silo equipped with a dust collection fan located between a ball mill and a silo. The feed end of the conveying pipe between the ball mill and the dust collection silo is below its discharge end. A discharge port is located at the end of the conveying pipe closest to the ball mill, and a discharge gate is installed at the discharge port. During the operation of the ball mill, the discharge gate is closed. After the material is crushed by the ball mill, it enters the conveying pipe. The dust collection fan draws the material in the conveying pipe into the dust collection silo for temporary storage. Steel balls that escape from the ball mill remain in the conveying pipe and roll down the conveying pipe from a high point to a low point near the discharge port at the end of the ball mill. When the ball mill stops operating, the discharge gate is opened to discharge the steel balls. This effectively prevents the steel balls from entering the silo with the material and subsequently entering the acid mixer, causing damage to the acid mixer. Discharging the steel balls from the discharge port prevents them from obstructing and accumulating in the conveying pipe, thus preventing blockage. The dust collection fan draws the material in the conveying pipe into the dust collection silo, preventing material accumulation and blockage, and keeping the conveying pipe unobstructed.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1As shown, this utility model discloses a material separation device, including a ball mill 1, a conveying pipe 2, and a hopper 6. The ball mill 1 and the hopper 6 are connected through the conveying pipe 2. A dust collection bin 4 is provided between the ball mill 1 and the hopper 6. The dust collection bin 4 is equipped with a dust collection fan 3. The ball mill 1, the dust collection bin 4, and the hopper 6 are sequentially connected through the conveying pipe 2. The inlet end of the conveying pipe 2 between the ball mill 1 and the dust collection bin 4 is located below its outlet end. A discharge port is provided at the end of the conveying pipe 2 near the ball mill 1 (near the inlet end of the conveying pipe 2), and the discharge port is equipped with a discharge door 7. The dust collection fan 3 is connected to the dust collection bin 4 to draw material from the conveying pipe 2 into the dust collection bin 4. The discharge door 7 can be installed at the edge of the discharge port using a hinged connection.

[0017] A material separation device based on the above structure includes a dust collection bin 4 equipped with a dust collection fan 3 located between the ball mill 1 and the silo 6. The inlet end of the conveying pipe 2 between the ball mill 1 and the dust collection bin 4 is below its outlet end. A discharge port is provided at the end of the conveying pipe 2 near the ball mill 1, and a discharge gate 7 is provided at the discharge port. During the operation of the ball mill 1, the discharge gate 7 is closed. After the material is crushed by the ball mill 1, it enters the conveying pipe 2. The dust collection fan 3 sucks the material in the conveying pipe 2 into the dust collection bin 4 for temporary storage. Steel balls that escape from the ball mill 1 remain in the conveying pipe 2. The steel balls roll down the conveying pipe 2 from a high position to a low position near the discharge port at the end of the ball mill 1. When the ball mill 1 stops working, the discharge gate 7 is opened to discharge the steel balls, effectively preventing the steel balls from entering the silo 6 with the material and subsequently entering the acid mixer, which could damage the acid mixer. Discharging the steel balls from the discharge port also prevents the steel balls from obstructing and accumulating the material in the conveying pipe 2, thus avoiding blockage of the conveying pipe 2. The dust collection fan 3 draws the material from the conveying pipe 2 into the dust collection bin 4, preventing material from accumulating and causing blockages in the conveying pipe 2, and keeping the conveying pipe 2 unobstructed. The power of the dust collection fan 3 is adjusted to be insufficient to draw in the steel balls.

[0018] As one possible implementation method, such as Figure 1 As shown, the conveying pipe 2 between the ball mill 1 and the dust collection bin 4 is a Z-shaped conveying pipe 2. The Z-shaped conveying pipe 2 includes a feeding section, a connecting section and a discharging section, and the discharge port is located in the feeding section.

[0019] The vertical connecting section acts as a barrier to prevent steel balls from escaping from the grinding mill, further preventing them from entering the dust collection chamber 4, thus providing better protection for the subsequent acid mixing machine.

[0020] As one possible implementation method, such as Figure 1 As shown, the feeding section is inclined, the feeding end of the feeding section is lower than its discharge end, and the discharge port is located close to the feeding end of the feeding section.

[0021] The steel balls that escape from the ball mill roll smoothly along the feed section to the discharge port, making it easy for the steel balls to be discharged.

[0022] As one possible implementation method, such as Figure 1 As shown, the discharge door 7 is equipped with a sealing ring.

[0023] A sealing ring, such as a rubber sealing ring, is set around the perimeter to achieve a sealing effect and prevent material from leaking from the gap between the discharge port 7 during the operation of the ball mill 1.

[0024] As one possible implementation method, such as Figure 1 As shown, the discharge end of the dust collection bin 4 is equipped with a discharge valve 5, and the discharge end of the discharge valve 5 is connected to the bin 6 through the conveying pipe 2.

[0025] Closing the discharge valve 5 allows materials to be temporarily stored in the dust collection bin 4. Opening the discharge valve 5 allows materials in the dust collection bin 4 to be placed into the silo 6. At the same time, the discharge valve 5 effectively prevents materials in the silo 6 from being sucked into the dust collection bin 4 by the dust collection fan 3.

[0026] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
