Abstract
Description
Technical Field
[0001] The utility model relates to the field of capsule filters, in particular to a capsule filter. Background Art
[0002] Capsule filters are generally used in the biopharmaceutical and industrial markets, and are usually used for filtering liquids on a small or pilot scale in laboratories. Capsule filters are generally equipped with a liquid inlet, a liquid outlet, an exhaust port, and a waste liquid outlet. At the beginning of the operation, slowly open the upstream valve of the filter to allow the liquid to be filtered to enter the capsule filter. Then, open the exhaust port at the top of the capsule filter to exhaust the air in the capsule filter, which ensures that the capsule filter membrane is filled with liquid. When the liquid begins to flow out of the exhaust port, close the exhaust port and start filtering.
[0003] However, the existing exhaust port needs to be closed by manually observing the liquid level and rotating the cap when the liquid level reaches a critical level, which is time-consuming and labor-intensive, and may easily cause the filtrate to overflow due to negligence, resulting in poor sealing stability of the exhaust port. Utility Model Content
[0004] The utility model aims to provide a capsule filter to solve the deficiencies of the prior art.

[0006] In the capsule filter as described above, the filter assembly includes a filter cartridge and a filter element. The filter element is arranged inside the filter cartridge. The filter element corresponds to the water outlet pipe. A cover plate is fixedly installed on the top surface of the filter cartridge.
[0007] A capsule filter, the exhaust assembly includes an exhaust cylinder, an exhaust pipe and a piston, the exhaust cylinder is fixedly mounted on the top surface of the cylinder body and communicates with the interior of the cylinder body, the piston is located in the exhaust cylinder and can move along the exhaust cylinder, the lower end of the exhaust pipe is fixedly connected to the top surface of the piston, the upper end of the exhaust pipe is fixedly mounted with a connecting plate, the connecting plate is located outside the exhaust cylinder, the top surface of the piston is fixedly connected to the top surface inside the exhaust cylinder by several springs, the springs always give the piston a downward thrust, and an exhaust hole is opened at the upper end of the exhaust pipe.
[0008] A capsule filter, wherein a valve is provided at the upper end of the sewage pipe.
[0009] Compared with the prior art, the beneficial effects of the utility model are: the exhaust closure of the device does not require manual control during use, and is not prone to overflow problems, effectively ensuring the stability of the exhaust closure of the airbag filter. The smooth section is conducive to the descent of the stable cover plate, thereby improving the smoothness of closing the exhaust pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0014] like Figure 1 As shown, a capsule filter specifically disclosed in this embodiment includes a barrel 1, a filter assembly 2 is arranged inside the barrel 1, and the filter assembly 2 includes a filter barrel 21 and a filter element 22, the filter element 22 is arranged inside the filter barrel 21, the filter element 22 corresponds to the water outlet pipe 4, and a cover plate 23 is fixedly installed on the top surface of the filter barrel 21. The liquid can filter larger impurities through the filter barrel 21, and can filter smaller impurities through the filter element 22.
