Description

Technical Field

[0001] The utility model relates to the technical field of dust removal for die-casting machines, in particular to dust removal equipment for die-casting machines. Background Art

[0002] Die casting machine is a machine used for pressure casting. It includes hot press chamber and cold press chamber. The latter is divided into two types: vertical and horizontal. The die casting machine hydraulically injects molten metal into the mold under pressure to cool and form. After the mold is opened, a solid metal casting can be obtained. During the die casting process, a large amount of waste gas will be discharged. The waste gas contains a large amount of harmful substances. Direct discharge will cause certain pollution to the environment. The existing way to deal with waste gas is to use a filter to filter the waste gas. However, the filter is easily blocked by debris during use, affecting the filtering and exhaust effect.

[0003] For example, in the Chinese patent application number 202222664452.2, during the die-casting process, certain ferromagnetic impurities will be mixed into the smoke, and the device is not equipped with a magnetic filter component to filter it. Ferromagnetic impurities will enter the filter and accumulate and clog it. It is difficult to completely remove it by manual cleaning, and it will soon be clogged again after cleaning, which will greatly shorten the service life of the filter and increase the cost of replacement.

This avoids the situation where the ferromagnetic impurities that are not removed will accumulate in the filter net or filter element and cause serious blockage, making it difficult to clean and can only be replaced. This can increase the service life of the filter net, reduce the frequency of replacement, and thus reduce unnecessary expenses to save costs.

By setting a hydraulic push rod to drive the foot pad to fall and prop up the device, the universal wheel can be lifted off the ground while maintaining the stability of the device, avoiding unnecessary displacement during the operation of the device. At the same time, the rubber foot pad can increase the friction with the ground to avoid sliding displacement of the device.

[0017] 3. By setting a slide rail with a movable slider, the cleaning brush can be driven to contact the magnetic net and move, which can be further processed to facilitate the cleaning of impurities and avoid excessive adsorption of impurities that may cause clogging of the sieve holes and affect use.
