Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically to an environmentally friendly grinding machine with self-recovery dust. Background Technology

[0002] Fully automatic CNC grinding machine tools are intelligent devices that achieve high-precision grinding through computer program control. Their core feature is the unmanned operation of the entire process, from workpiece clamping to machining and inspection, achieved through digital programming and automated systems. They are widely used in the field of precision manufacturing.

[0003] Chinese patent CN220533841U discloses "a grinding machine with dust recovery function". When the grinding mechanism is grinding, the dust generated during grinding is driven by a centrifugal fan and enters the dust collection port. The dust then enters the centrifugal fan through a connecting pipe, and the centrifugal fan guides the dust into a storage box through a discharge pipe. The storage box is equipped with a dust collection filter bag to collect the dust introduced by the discharge pipe, thereby reducing the dust from spreading and preventing the phenomenon of debris or dust splashing. It also facilitates centralized processing, playing a role in dust collection and removal, and improving the working environment.

[0004] In this grinding machine device, the airflow generated by the centrifugal fan transports the dust produced during the grinding process to the storage tank through the dust collection port and connecting pipes. The dust collection filter bags installed in the storage tank mechanically intercept the incoming dust according to the interception principle of porous media and cause it to be deposited on the surface of the filter bags. With continuous operation, the dust gradually accumulates inside the filter bags to form a dense filter layer. According to the resistance theory in fluid mechanics, as the thickness of the filter layer increases, the resistance encountered by the airflow when passing through the filter bags increases, resulting in a decrease in system pressure and a reduction in fan suction. This leads to a slowdown in airflow velocity, a decrease in kinetic energy, and a decrease in dust collection efficiency. The effective filtration area inside the filter bags decreases due to deposition. According to classical filtration theory, under the combined effects of the transport and interception laws of particulate matter in laminar and turbulent states and electrostatic adsorption, the degree of filter bag clogging continuously worsens, thus reducing fan suction and consequently decreasing dust removal efficiency.

[0005] In view of this, we propose an environmentally friendly grinding machine with self-recycling dust. Utility Model Content

[0006] The purpose of this utility model is to provide a dust self-recovery environmentally friendly grinding machine, which solves the problem that dust removal efficiency will significantly decrease as dust continuously accumulates on the filter bag to form a dense filter layer.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] An environmentally friendly grinding machine with self-recovery dust includes a machine body and a grinding head. The machine body is equipped with a dust collection mechanism for sucking up dust generated during the grinding process. The dust collection mechanism includes a telescopic hose, a vertical air duct, an inlet, a hollow connecting block, a filter screen, a semi-circular hollow component, a connecting pipe, and an annular hollow block. The machine body is also equipped with a collection mechanism for collecting the dust sucked up by the dust collection mechanism. The collection mechanism includes an impeller rotatably connected to the inner wall of the hollow connecting block. A cleaning component is fixedly connected to the shaft of the impeller. A collection box is fixedly connected to the hollow connecting block by bolts. A through groove is formed on the inner wall of the hollow connecting block, and a through hole is formed on the outer wall of the collection box, which aligns with the through groove. A connecting rod is fixedly connected to the shaft of the impeller. An axial air inlet and a vertical air outlet are formed on the connecting rod of the impeller. A second filter screen is fixedly connected to the bottom of the collection box.

[0009] Preferably, the machine body is provided with a grinding head for grinding the surface of the workpiece.

[0010] Preferably, a telescopic hose is fixedly connected to the inner wall of the machine body. One end of the telescopic hose is fixedly connected to a vertical air duct. An inlet is fixedly connected to the top of the vertical air duct. A hollow connecting block is fixedly connected to the bottom of the vertical air duct. A filter screen is fixedly connected to the inner wall of the hollow connecting block. A semi-circular hollow component is fixedly connected to the other end of the telescopic hose. One end of a connecting pipe is fixedly connected to the bottom of the semi-circular hollow component. The other end of the connecting pipe is fixedly connected to an annular hollow block. The bottom of the annular hollow block is in communication with the outside air.

[0011] Preferably, the semi-circular hollow component is fixedly connected to the outer wall of the grinding head to provide fixed support for the semi-circular hollow component.

[0012] Preferably, the inner walls of the semi-circular hollow component, the connecting pipe, and the annular hollow block are hollow.

[0013] Preferably, the cleaning element is arc-shaped to facilitate pushing dust into the passageway.

[0014] Preferably, the hollow connecting block is fixedly connected to the back of the machine body to provide fixed support for the hollow connecting block.

[0015] By employing the above technical solution, this utility model provides an environmentally friendly grinding machine with self-recovering dust. It possesses at least the following beneficial effects:

[0016] 1. This utility model incorporates a collection mechanism that allows dust to be drawn into the hollow connecting block by air and filtered by the filter screen. High-pressure air drives the impeller to rotate, which in turn drives the cleaning component to clean the surface of the filter screen. The dust is then pushed into the collection box through a channel. As the impeller drives the connecting rod to rotate, the connecting rod on the impeller drives the axial air inlet to rotate. During the rotation of the axial air inlet, outside air enters the axial air inlet and then blows upward through the vertical air outlet, causing the dust inside the filter screen to be blown out. This facilitates cleaning by the cleaning component and ensures that the filter screen always maintains a high filtration efficiency.

[0017] 2. This utility model incorporates a dust collection mechanism. Based on Bernoulli's principle, the telescopic hose generates negative pressure to create a strong adsorption force. This adsorption force, through the semi-circular hollow component, connecting pipe, and annular hollow block, adsorbs the dust generated during the grinding head's operation, achieving dust self-recycling and environmentally friendly dust removal.

A collection mechanism 4 is installed on the machine body 1. The collection mechanism 4 is used to collect the dust sucked up by the dust collection mechanism 3. The collection mechanism 4 includes an impeller 41, which is rotatably connected to... A cleaning component 42 is fixedly connected to the shaft of the impeller 41 on the inner wall of the hollow connecting block 34. A collection box 43 is fixedly connected to the hollow connecting block 34 by bolts. A through groove 44 is opened on the inner wall of the hollow connecting block 34. A through hole is opened on the outer wall of the collection box 43. The through hole on the collection box 43 is connected to the through groove 44. A connecting rod is fixedly connected to the shaft of the impeller 41. An axial air inlet 45 is opened on the connecting rod of the impeller 41. A vertical air outlet 46 is opened on the connecting rod of the impeller 41. A filter screen 47 is fixedly connected to the bottom of the collection box 43. A grinding head 2 is provided on the machine body 1 for grinding the surface of the workpiece to improve dimensional accuracy and surface finish.

[0031] A flexible hose 31 is fixedly connected to the inner wall of the body 1. One end of the flexible hose 31 is fixedly connected to a vertical air duct 32. The top of the vertical air duct 32 is fixedly connected to an inlet 33 for connecting to an air compressor. A hollow connecting block 34 is fixedly connected to the bottom of the vertical air duct 32. A filter screen 35 is fixedly connected to the inner wall of the hollow connecting block 34. The other end of the flexible hose 31 is fixedly connected to a semi-circular hollow component 36. One end of a connecting pipe 37 is fixedly connected to the bottom of the semi-circular hollow component 36. The other end of the connecting pipe 37 is fixedly connected to... A ring-shaped hollow block 38 is connected, with its bottom communicating with the outside air. The ring-shaped hollow block 38 is used to adsorb the debris generated by the grinding head 2. A semi-ring-shaped hollow part 36 is fixedly connected to the outer wall of the grinding head 2 to provide fixed support for the semi-ring-shaped hollow part 36.

High-pressure air drives the impeller 41 to rotate, and the impeller 41 drives the cleaning component 42 to clean the surface of the filter screen 35. The dust is pushed into the collection box 43 through the channel 44. When the impeller 41 drives the connecting rod to rotate, the connecting rod on the impeller 41 drives the axial air inlet 45 to rotate. During the rotation of the axial air inlet 45, outside air enters the axial air inlet 45 and blows upward through the vertical air outlet 46, causing the dust in the mesh of the filter screen 35 to be blown out, which is convenient for the cleaning component 42 to clean and ensure that the filter screen 35 always maintains a high filtration efficiency.

[0034] Simply remove the collection box 43 periodically and empty the dust.
