Description

Technical Field

[0001] The utility model relates to the field of filtering devices, in particular to an automatic feeding filtering device for laundry detergent. Background Art

[0002] When producing laundry detergent, the raw materials need to be pumped from the storage tank into the reactor used for production. In order to ensure the quality of the laundry detergent, it is necessary to ensure that there are no excessive impurities in the raw materials. In order to improve the purity of the raw materials, traditionally, a filter device is installed on the pipe between the storage tank and the reactor to filter the material in the raw materials.

[0003] A Chinese patent with announcement number CN217391752U discloses a large-aperture chemical pipeline filter, including a pipe body, a connecting flange at the front end and the rear end of the pipe body, and a filter screen in the pipe body. After the filter has been used for a period of time, a certain amount of impurities will accumulate on the surface of the filter screen, which will reduce the filtering performance of the filter screen. Therefore, in order to ensure the filtering performance of the filter screen, the filter screen needs to be regularly removed from the pipe body for cleaning. When cleaning the filter screen of the filter, the bolts on the connecting flanges at the front and rear ends of the pipe body need to be removed one by one before the pipe body can be removed from the pipe, and then the filter screen in the pipe body can be removed for cleaning. Therefore, each time the filter screen is cleaned, it takes a lot of time to disassemble and install the pipe body. Utility Model Content

The whole process is simple and quick.

[0008] Preferably, an annular receiving groove is provided on the inner wall of the hoop of the second clamp, and the annular receiving groove is used to receive the first connecting disk and the second connecting disk.

[0009] By adopting the above technical solution, the provision of the annular accommodating groove can improve the limiting effect of the second clamp on the first connecting disk and the second connecting disk.
