AI Technical Summary
During the graphite electrode processing process, traditional vacuum cleaner brush heads are difficult to effectively collect and adsorb debris from graphite electrode connectors, causing debris to splash or fall, causing environmental pollution and equipment damage.
A graphite electrode joint chip collection device is designed, using a brush brush head with different lengths of bristles. The bristles are designed to fit the shape of the graphite electrode joint, ensuring that the bristles can effectively brush and hold the debris, avoid debris falling, and suck the debris away through the negative pressure airflow of the vacuum hose.
The device can effectively collect and adsorb debris from graphite electrode joints, reduce splashing and drop of debris, improve the collection efficiency of debris, protect the workshop environment, and reduce stress damage to graphite electrodes.

Abstract
Description
Technical Field
[0001] This application introduces a technology for collecting machining dust, especially a dust collection device for machining dust of graphite electrodes. Background Art
[0002] The dust suction hose is commonly made of nylon mesh cloth, polyester, thermoplastic or PVC. Generally, it has a retractable design and has characteristics such as high temperature resistance, oil and acid resistance, flame retardancy, insulation, free connection, and light weight.
[0003] Vacuum cleaners can be divided into upright, horizontal and portable types according to their structures. The working principle of a vacuum cleaner is that an electric motor drives the blades to rotate at high speed, generating a negative air pressure in the sealed housing to suck up dust debris. A brush head is usually provided at the end of the vacuum cleaner to agglomerate dust debris. The lengths of the bristles on the traditional brush head are the same and are evenly arranged at the end of the vacuum cleaner, and dust debris may leak. Summary of the Invention
[0004] Purpose of the Utility Model:
[0005] To provide a graphite electrode joint debris collection device in which debris is not easily splashed or dropped.
[0006] Technical Solution:
[0007] The graphite electrode joint debris collection device of this application is composed of a dust suction hose and a brush head. The dust suction hose can be a straight pipe or a bent pipe. The brush head has a brush sleeve in the shape of a cylindrical shell; one end of the brush sleeve can be movably connected (fastened by a pipe clamp or screwed by a thread) to one end of the dust suction hose, and bristles arranged around the circumference are provided on the end circumference of the other end of the brush sleeve.
[0008] Since the central axis of the graphite electrode joint is horizontally placed during processing, its processing surface is two circular table surfaces with large bottom surfaces facing each other, and the middle part is in a convex shape. The brush head of the vacuum cleaner does not contact a flat surface, but mainly two circular table surfaces with a flange in the middle.
[0009] Preferably, the bristles have different lengths. The bristles on both sides are shorter, and the bristles on the lower side are longer. When the bristles on both sides contact the circular table surface, the lower bristles cover the lower part of the circular table surface and continue to extend forward, so that the ends of the bristles extend beyond the projection of the entire cylindrical surface in the vertical direction, and can hold and collect the debris on the cylindrical surface without falling to the bottom surface, and then be sucked away under the action of the negative pressure air flow in the dust suction hose.
[0010] Further preferably, the length of the upper bristles is slightly longer than that of the bristles on both sides, so as to contact the upper circular table surface and brush out the debris generated during the processing on the circular table surface; the lower bristles are longer than the upper bristles, so that both the bristles on both sides and the upper bristles are scraping the debris, and the lower part holds and collects the debris, so that the debris on the entire circular table surface can be collected and then adsorbed and conveyed away.
[0011] Or the upper bristles extend after contacting the circular table surface, which can prevent debris from floating into the air.
[0012] Beneficial effects:
[0013] The debris collection device of the present application can fit the shape of the graphite electrode joint; brush out debris on the circumference, with a hollow in the center, and there is almost no stress damage to the graphite electrode; the upper side and both sides are in contact with the circular table surface of the electrode joint, and the lower side not only contacts the lower part of the circular table surface, but also extends beyond the space where the electrode is located, so that the machining debris on the electrode surface can be collected and adsorbed, and the lower part holds to prevent the debris from falling to the ground, maximizing the collection and adsorption of the machining debris, and the workshop environment is better.
