Screen convenient to clean

Abstract

The invention discloses a screen convenient to clean. The screen comprises a screen body, a base, vibration rods and supporting frames. The supporting frames are installed at the two ends of the base. The screen body is arranged on the supporting frames. The supporting frames and the screen body are connected through the vibration rods. The vibration rods are sleeved with supporting springs. The screen has the beneficial effects that the structure is simple, the springs have the buffer effect, stability is improved, the screen is convenient to clean and replace, screws are adopted, and detachment is convenient.

Description

technical field [0001] The invention relates to a screen, in particular to a convenient cleaning screen. Background technique [0002] The foundry industry will discharge a large amount of solid waste during production, mainly old sand. The random discharge of old sand will pollute the environment and waste resources, and it is bound to recycle the old sand. At the same time, compared with new sand, regenerated sand has less rapid thermal expansion, better thermal stability, rounded particle shape, improved angular coefficient, and also improves the air permeability of the prepared molding sand, reducing the generation of casting defects and waste products such as pores, which is also beneficial. The use of finer sand to improve the surface accuracy and quality of castings has three benefits in terms of economy and resources, environmental protection, and technology and quality improvement. [0003] After pouring and cooling, the casting mold is hoisted by the crane to the...

AI Technical Summary

Problems solved by technology

Because the old sand is subjected to high temperature during casting, a large amount of old sand is agglomerated and agglomerated, and the old sand also contains sundries. To regenerate the old sand, the old sand must first be screened by a screening device, and then the old sand The impurities also contain a large amount of iron-containing substances. The iron-containing substances and old sand agglomerates directly contact with the screen and easily damage the screen. At the same time, after a period of use, the screen holes on the screen will be blocked by debris. The screening effect requires regular replacement of the screen. The existing screen structure usually installs the screen on the bottom plate of the screen and presses the screen pressure plate on the screen, and then installs the screen structure on the equipment. The existing screen It is inconvenient to install and replace the structure, it is inconvenient to clean the screen, and the screen is easily damaged
