Technical Field
[0001] The utility model relates to the field of screening devices, in particular to a screening device for processing chemical raw materials. Background Art
[0002] At present, the Chinese utility model with the announcement number CN214320838U discloses a chemical raw material screening device that can avoid clogging by large particles, including a main frame and a dust cover, a feed port is arranged on the upper part of the interior of the main frame, and the inner walls on the left and right sides of the main frame are provided with sliding tracks, the internal pulley of the sliding track is connected with a coarse screen, and a fine screen is arranged below the coarse screen, and a collection drawer is arranged below the fine screen, and the dust cover is arranged above the main frame, and a sealing gasket is arranged on the inner side of the dust cover. A chemical raw material screening device that can avoid clogging by large particles, by setting a fine screen, so that when pouring chemical raw materials, firstly through the coarse screen for primary screening, then fall into the fine screen for secondary screening, and screen out larger particles, avoid clogging due to more large particles of raw materials during the screening process, resulting in excessive internal pressure of the device, bringing safety hazards, and improving the safety and work efficiency of the device.
[0003] Although the existing device can perform double-layer screening of chemical raw material particles through coarse and fine screens, and can avoid blockage caused by excessive accumulation of large particles, there are still other problems during use. For example, it does not have a dust collection and filtering function, and cannot absorb the smoke generated during the vibration screening of the raw materials. In addition to particulate matter, the raw materials also contain a certain amount of dust. The dust will float outward during vibration. If inhaled by people, it will cause damage to the respiratory tract, and it is not convenient to collect the raw materials. After the raw materials and particulate matter are graded in the device, they will be intercepted inside and cannot fall down by themselves. When the raw materials or particulate matter accumulate too much, the personnel are required to shut down the device and then manually pull out the screen for collection, which increases the workload of the personnel and has poor practicality. In order to solve the above-mentioned problems, we propose a screening device for chemical raw material processing. Utility Model Content
