Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to an iron chip recovery device for a machining workshop. Background Art

[0002] There are machine tools, milling machines and other mechanical processing equipment in the machining workshop. In daily production, a large amount of iron filings are generated, and most of the iron filings are directly collected in the iron filing car through the conveyor belt. However, there are still small particles of iron filings splashed onto the ground and need to be cleaned regularly.

[0003] In this regard, China's patent application number CN201920719769.7 discloses an iron chip recovery device for steel workshop production. The scheme mainly uses a negative pressure fan to suck the iron chips and dust on the ground into the suction nozzle. When passing through the first shell, the iron chips are sucked away by the electromagnetic suction cup, and the dust enters the second shell, realizing the separation of iron chips and dust. When a large amount of iron chips are collected, the negative pressure fan and the electromagnetic suction cup are turned off, and then the iron chips will lose their adsorption force, thereby cleaning out the iron chips.

[0004] However, in the process of implementing the technical solution in the embodiments of the present application, the inventor of the present application found that the above technology has at least the following technical problems:

[0005] 1. Iron chips often have a mucous film formed by cutting fluid, which is easy to stick to dust. Even if the iron chips are sucked away, the dust will be taken away at the same time, resulting in poor separation effect;

[0006] 2. Iron filings are stored on an electromagnetic chuck with limited capacity and need to be cleaned frequently. Utility Model Content

[0014] In the above implementation process, the filter can block the dust in the dust chamber, and the filter is inserted to facilitate replacement.

[0015] In a specific embodiment, the dust collecting member further includes an air guide plate, and an iron chip channel is formed between the air guide plate and the magnetic roller and is connected to the return flow channel.

[0016] In the above implementation process, a narrow passage is formed between the air guide plate and the magnetic roller, which facilitates the airflow to form pressure and blow the dust on the iron filings off.

[0017] In a specific embodiment, the air guide plate is Y-shaped, and the air guide plate is also used to guide dust into the dust chamber.

Among them, the magnetic roller 50 is used to move the chip into the chip chamber 60 along the chip guide plate 30, and the airflow generated by the dust collecting member 20 is reversely blown to the chip on the chip guide plate 30, and the dust mixed on the chip is blown off, and then sucked away by the air suction port, thereby achieving a better separation effect of chip and dust, and the chip chamber 60 has a larger capacity, which reduces the frequency of cleaning.

[0031] See also Figure 1-Figure 3 A motor is arranged in the magnetic roller 50. The motor adopts a brushless motor, with a stator at the center, both ends of the stator fixed on the vehicle body 10, and a rotor rotating outside the stator. A magnetic shield is placed on the periphery of the rotor, and then a magnet is arranged outside the magnetic shield. The magnet rotates under the chip guide plate 30, and the iron chips are pulled by the magnet on the surface of the chip guide plate 30 to the rear iron chip chamber 60.

[0032] See also Figure 1-Figure 3 A dust chamber 70 is provided in the vehicle body 10, and the dust collecting member 20 includes a fan 21, and the fan 21 is located at the rear wall of the dust chamber 70. When the vehicle body 10 is pushed forward, the fan 21 rotates to suck up the dust through the air suction port, and the iron filings are kept on the ground due to their own weight.

[0033] See also Figure 1-Figure 3 The dust collecting member 20 further includes a filter screen 22, which is plugged into the vehicle body 10 and is blocked in front of the fan 21. The filter screen 22 can block dust in the dust chamber 70, and the filter screen 22 is inserted in an insertion manner for easy replacement.

[0034] See also Figure 1-Figure 3 The dust collecting member 20 further includes an air guide plate 23, and an iron filings channel is formed between the air guide plate 23 and the magnetic roller 50 and communicates with the return flow channel 40. A narrow channel is formed between the air guide plate 23 and the magnetic roller 50, which facilitates the air flow to form pressure and blow the dust on the iron filings off.

[0035] See also Figure 1-Figure 3 The air guide plate 23 is Y-shaped, and the air guide plate 23 is also used to guide the dust to the dust chamber 70. The dust enters the dust chamber 70 along the air guide plate 23 and is collected, and is not easy to leak out.

[0036] See also Figure 1-Figure 3 A return plate 80 is provided at the rear of the vehicle body 10, and the return plate 80 blocks part of the air outlet of the fan 21 and guides part of the airflow to the return channel 40. The fan 21 blows air backward, and part of the airflow is returned to the return channel 40 through the arc-shaped return plate 80.

The iron chips are kept on the ground due to their own weight, and continue to contact the chip guide plate 30 and the baffle 90 backward. The iron chips are carried up by the magnetic roller 50 with the dust, and the mixture moves toward the iron chip chamber 60 along the gap between the chip guide plate 30 and the air guide plate 23. At the same time, the fan 21 sucks air from the dust chamber 70 and blows it backward. Part of the airflow is returned to the return channel 40 through the arc-shaped return plate 80, and the airflow blows through the chip guide plate 30 and the air guide plate in the reverse direction. 23, the dust is blown down, and the air flow carries the dust into the dust chamber 70 through the suction port, and the iron filings with the dust blown off continue to move backward with the magnetic roller 50 until the tail of the chip guide plate 30 is separated from the magnetic roller 50, and the iron filings lose the magnetic effect and slide into the iron filing chamber 60, thereby achieving the separation of dust and iron filings. In summary, the magnetic roller 50 is used to move the iron filings along the chip guide plate 30 into the iron filing chamber 60, and the air flow generated by the dust suction part 20 is used to blow the iron filings on the chip guide plate 30 in the reverse direction, and the dust mixed with the iron filings is blown off, and then sucked away by the suction port, thereby achieving a better separation effect of iron filings and dust, and the iron filing chamber 60 has a larger capacity, which reduces the frequency of cleaning.
