Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a phenolic resin particle screening device. Background Art

[0002] In the actual screening process of the phenolic resin particle screening device under the existing technology, most of the materials are added manually, and some are fed by machine. However, a problem inevitably arises. That is, since the filter of the screening device is set at an angle, once too much material is added at a time, some of the material will not be filtered through the fine-pore filter and will be vibrated to the coarse-pore filter and fall, resulting in low screening accuracy.

[0003] In order to solve the above problems, patent CN202321566857.0 discloses a phenolic resin particle screening device, which can block the added phenolic resin particles and unload them in time to avoid blockage, thereby preventing the phenolic resin particles from being discharged without screening. At the same time, it can perform periodic jacking unloading to achieve uniform unloading of phenolic resin particles, ultimately ensuring the screening accuracy.

[0004] The following defects and shortcomings exist in the specific implementation process: too much material is added at a time, and the phenolic resin is easily accumulated on the screen to cause blockage. Vibration alone cannot make the phenolic resin quickly disperse and fall off, affecting the screening efficiency and screening accuracy. Therefore, we propose a phenolic resin particle screening device to solve the above problems. Utility Model Content
