Description

Technical Field

[0001] The utility model relates to the technical field of chemical filtration, in particular to a filtration device. Background Art

[0002] In the fine chemical industry, the filtration of the medium is a very important link. This link affects the purity and quality of the product. In order to meet the cleanliness requirements of the fluid in the filter slurry in chemical production, filter materials are often used in industry to intercept solid particle impurities in the filter slurry. According to the patent document with the publication number CN209092797U, a chemical filtration device is disclosed, which belongs to the technical field of chemical equipment. It includes a shell, a flange cover, a skeleton and a filter screen, a buffer tank and a vacuum pump. The flange cover is connected to a liquid inlet pipe, and the lower end of the liquid inlet pipe is connected to a distributor. The distributor is located above the filter screen. The middle part of the skeleton body is conical and grooves are provided at both ends. The filter screen covers the upper surface of the skeleton. The pressure ring fixes the two ends of the filter screen in the groove. The side of the shell is provided with a side door, and the side door is located above the skeleton. The side of the shell is also connected to a liquid outlet pipe, and the liquid outlet pipe is located below the skeleton. One end of the liquid outlet pipe is connected to the buffer tank, and the side of the buffer tank is also connected to a vacuum pump. The filter of the utility model is cone-shaped. When the filter device is working, the liquid in the liquid inlet pipe can flush the solid matter accumulated on the surface of the filter to avoid clogging of the filter, greatly improve the filtering effect and reduce the number of cleaning times. A distributor is provided to disperse the material to be filtered before filtering, and the filtering effect is good. The existing filter device flushes the solid matter accumulated on the surface of the filter through the liquid in the liquid inlet pipe to prevent the filter from being blocked. However, in the actual cleaning process, although some impurities on the surface of the filter can be flushed and cleaned, due to the single flow direction of the liquid, it is easy to have a counter-effect on the cleaning of impurities mixed in the filter holes, causing solid particles to be flushed into the filter holes and stuck. For this reason, we propose a filter device that can improve the cleaning strength of the filter. Utility Model Content
