Description

Technical Field

[0001] This utility model relates to the field of iron ore screening technology, and more specifically, to a multi-stage iron ore screening device. Background Technology

[0002] When testing iron ore, sampling is required. However, some testing departments use equipment to screen the iron ore for testing. Existing equipment only performs simple screening of iron ore through a screen cylinder, which cannot completely separate the coarse and fine iron ore and has low screening efficiency, thus affecting the efficiency of subsequent iron ore testing.

[0003] To address the aforementioned issues, patent document publication number CN219560406U discloses a screening device for iron ore testing, comprising a base, a screening box mounted on the top of the base, a feed hopper mounted at one end of the top of the screening box, a first screen plate, a second screen plate, and a third screen plate sequentially mounted at an incline from top to bottom within the screening box, the apertures of the first screen plate, the second screen plate, and the third screen plate decreasing sequentially from top to bottom, and a material receiving assembly provided on the inner bottom wall of the screening box.

[0004] However, it still has some drawbacks in actual use. For example, the device will inevitably generate a lot of dust during the screening of ore. The screening device only has a door on the screening box, but the discharge port is an open design. The whole system is not a closed structure, which can easily lead to dust dispersion and reduce the practicality of the device to a certain extent. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-stage iron ore screening device to solve the problem that the prior art device cannot handle the loose dust in a timely manner.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-stage iron ore screening device, including a screening box, an installation plate being provided on the left side of the screening box, and the multi-stage iron ore screening device further includes...

[0007] The dust inlet chamber is disposed through the surface of the mounting plate on one side opposite to the screening box. A fitting frame is fixedly installed around the dust inlet chamber, and one side of the fitting frame is fitted to the surface of the mounting plate.

[0008] A fixed box is fixedly installed on the top surface of the mounting plate. A fan is provided on the left side of the fixed box. The port of the fan is connected to the side of the fixed box through a connecting pipe. A collection chamber is detachably installed inside the fixed box. A barrier net is provided on the left side of the collection chamber. A pull block is fixedly installed on the front of the collection chamber.

[0009] A connecting hose is provided, one end of which passes through the right side of the fixed box and is connected to the right side of the collection chamber. A plug is provided on the surface of the connecting hose, and one end of the plug is inserted into the side of the dust inlet chamber. A fitting ring is provided on the outer wall of the plug, and the surface of the fitting ring is fitted to the right side of the dust inlet chamber.

[0010] It also includes a fixed base, which is disposed opposite to the sides of the top and bottom of the dust inlet chamber. A spring is fixedly connected to the inner wall of the fixed base. A connecting post is fixedly connected to one end of the spring opposite to the fixed base. The side of the connecting post is slidably connected to the inner wall of the fixed base. A snap-fit ​​plate is provided on the bottom surface of the connecting post. The surface of the snap-fit ​​plate is in contact with the surface of the fitting ring.

[0011] The device also includes a fixing frame, a connecting seat on one side of the fixing frame, and the connecting seat is fixedly connected to the surface of the mounting plate on the side opposite to the fixing frame. A second spring is fixedly connected to the bottom of the fixing frame, and an abutment plate is fixedly connected to the top of the second spring. The top of the abutment plate is engaged with the bottom surface of the dust inlet chamber. Limiting plates are provided on both sides of the abutment plate along its length, and the surface of the limiting plates is slidably connected to the surface of the fixing frame.

[0012] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0013] In the above scheme, during the screening of ore using the device, a certain amount of air force is generated by a fan set on one side of the fixed box. The generated air force creates a negative pressure area at the dust inlet chamber to absorb the dust escaping from the opening of the mounting plate. After entering the dust inlet chamber, the dust enters the connecting hose through the insertion pipe and finally enters the collection chamber. It is blocked by the barrier net set on the left side of the collection chamber, so that the dust can be retained in the collection chamber. Subsequently, the collection chamber can be moved horizontally out of the fixed box by the pull block to uniformly process the collected dust. This achieves the immediate treatment of the escaping dust and avoids the dust spreading and affecting the surrounding environment. In addition, the connecting column set in the fixed seat is moved upward, so that the snap plate moves synchronously and disengages from the fitting ring. Afterward, the insertion pipe can be pulled out from the right end of the dust inlet chamber to clean the insertion pipe port and prevent it from being blocked and affecting the collection of dust.

[0014] By moving the abutment plate downwards, the second spring located between the fixed frame and the abutment plate is compressed. At the same time, the top of the abutment plate separates from the bottom surface of the dust inlet chamber. At this point, the dust inlet chamber can be moved horizontally, allowing it to be disassembled from the surface of the mounting plate. This facilitates cleaning of the dust inlet inside the dust inlet chamber, preventing dust accumulation from clogging the inlet and ensuring that the dust collection work can proceed normally, thus further improving the practicality of the device.

[0029] The working process of this utility model is as follows: When the device is used to screen the ore, a certain amount of wind is generated by the fan 6 set on one side of the fixed box 5. The generated wind creates a negative pressure area at the dust inlet chamber 3 to absorb the dust that escapes from the opening of the mounting plate 2. After the dust enters the dust inlet chamber 3, it enters the connecting hose 10 through the plug pipe 11 and finally enters the collection chamber 7. It is blocked by the barrier net 8 set on the left side of the collection chamber 7, so that the dust can be retained in the collection chamber 7. Subsequently, the collection chamber 7 can be moved horizontally out of the fixed box 5 by the pull block 9 for unified treatment of the collected dust.
