Description

Technical Field

[0001] The utility model relates to the technical field of melamine powder, in particular to a melamine powder outlet filtering device. Background Art

[0002] Melamine formaldehyde molding compound (commonly known as melamine powder) can be widely used in melamine tableware, imitation porcelain tableware, medium and low voltage electrical appliances, etc. Melamine powder is a powdered solid. In the prior art, the discharging device of the melamine grinder filters the melamine powder through a series of filtering devices to improve the purity of the processed melamine powder and ensure the quality of the subsequent processed products. People only consider ensuring the purity of the melamine powder. Although melamine powder itself is non-toxic, it is a powdered solid with extremely light weight and is easy to float in the air, causing serious air pollution. In addition, when there is a high density in the air, the melamine powder will be easily polluted. When the melamine powder is inhaled by the human body, it will cause great harm to the human body and threaten the human life safety; after the melamine powder is processed, it needs to be collected through a collection box. When the collection box is full, it needs to be replaced with another collection box. At this time, due to the need for production efficiency, the machine is usually not shut down. In the process of replacing the collection box, the melamine powder is still being produced, causing the melamine powder to be scattered on the ground, which has the problem of waste of resources. The melamine powder is scattered on the ground. When the wind blows, it will also increase the content of melamine powder in the air and increase the pollution to the air. In the manufacturing process of melamine powder, mechanical transmission parts such as bearings and conveyor belts are used. These mechanical transmission parts will be worn during use, and the worn iron powder will be mixed into the melamine powder. The mesh filter device usually cannot filter out the iron powder with the same particle size as the melamine powder. However, if the iron powder is not removed from the melamine powder, it will affect the product quality of melamine plastic. For this reason, we provide a melamine powder outlet filter device.

[0003] The publication number in the existing public technology is: CN211838445U. A melamine powder outlet filter device comprises a filter box, a feeding structure is welded on the top of the filter box, a magnetic powder collecting structure is embedded and connected inside the filter box, and the connection between the magnetic powder collecting structure and the filter box is sealed by a rubber sealing gasket, and the middle parts of the left and right sides of the filter box are detachably connected with a magnetic powder recovery structure by bolts, and the bottom end of the filter box is fixedly connected with a discharge pipe, and the magnetic powder collection structure drives the magnet stirring rod to rotate when the melamine powder passes through the filter box, so as to collect the magnetic powder in the melamine powder and improve the purity of the melamine powder. At the same time, the collection frame can be taken out by the handle to facilitate the cleaning of the magnetic powder. Through the magnetic powder recovery structure, the exhaust fan can be turned on to draw the melamine powder in the outside air into the dust collecting bag through the filter net for recovery, and at the same time, the magnetic powder on the melamine powder is adsorbed and filtered by the magnetic strip, and the activated carbon filter layer prevents the melamine powder from leaking and polluting the air.

[0004] However, the above patent still has certain disadvantages when used: although the magnetic powder in the melamine powder can be filtered and collected by rotating the magnetic stirring rod, during the collection process, the magnetic powder will continue to adhere to the magnetic stirring rod until its surface is completely covered. At this time, if the magnetic powder on the surface is not processed first, the subsequent magnetic powder will not be attracted by the magnetic stirring rod, thereby losing the filtering function.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
