Novel air suction opening device for dust removal of sharpening machine

Abstract

The utility model discloses a novel dust-removing exhaust inlet device of a sharpening machine, which comprises an L-shaped bent pipe, one end of the L-shaped bent pipe is provided with an air outlet, the other end of the L-shaped bent pipe is connected with one end of an air expansion pipe, and the other end of the air expansion pipe is connected with an exhaust inlet. The air suction opening device is large in air suction amount, slag blocking of an air suction opening is not prone to being caused, and stable operation of equipment is guaranteed. In addition, the slag removal frequency of workers is reduced, the labor intensity of the workers is reduced, and meanwhile the environment around the sharpening machine is more effectively improved.

Description

Technical Field

[0001] The utility model belongs to the technical field of power equipment, and in particular relates to a new type of dust suction port device for a grinding machine. Background Art

[0002] The existing dust removal air intake design of the Danieli synchronous belt grinding machine in the workshop is defective, which leads to the accumulation of slag in the air intake and easy blockage during production, poor dust removal effect, and the heat in the grinding machine room cannot be removed in time, causing frequent high-temperature shutdown of the equipment, affecting production efficiency. Therefore, it is urgent to design a new dust removal air intake device to solve the existing problems. Utility Model Content

[0003] Technical problem solved: In view of the above technical problems, the utility model provides a new dust suction port device for a grinding machine, which effectively solves the problems of easy blockage of slag accumulation and poor dust removal effect in the existing suction port, thereby ensuring the normal operation of the grinding machine and improving production efficiency.

[0004] Technical solution: A new air suction port device for dust removal of a grinding machine comprises an L-shaped elbow, one end of the L-shaped elbow is provided with an air outlet, and the other end is connected to one end of an air expansion pipe, and the other end of the air expansion pipe is connected to the air suction port.

[0005] Preferably, the air diffusion pipe has a trapezoidal longitudinal section, one end of the short bottom side of the air diffusion pipe is connected to the L-shaped elbow, and one end of the long bottom side is connected to the air suction port.

[0006] Furthermore, the side length of the air suction port is greater than the long bottom side length of the air expansion pipe.

[0007] Preferably, the plane where the opening end of the air suction port is located is perpendicular to the plane where the opening end of the air diffusion pipe is located.

[0008] Preferably, the air suction port is provided with a protective net.

[0009] Beneficial effects: The utility model suction port device not only has a large air suction volume and is not prone to slag blockage at the suction port, but also ensures the stable operation of the equipment; in addition, it reduces the frequency of slag cleaning for employees, reduces the labor intensity of employees, and more effectively improves the environment around the grinding machine.
