Description

Technical Field

[0001] The utility model relates to the technical field of plate-frame filters, and more specifically to a multi-layer plate-frame filter. Background Art

[0002] Injection is a drug dosage form, which refers to sterile solutions, emulsions or suspensions made of drugs that can be injected into the body, as well as sterile powders or concentrated solutions for preparation into solutions or suspensions before clinical use. Filtration is an important step in the production of injections. The main purpose is to remove impurities and microorganisms in the drug solution to ensure the quality and safety of the injection.

[0003] The multi-layer plate and frame filter is a common filtering equipment, which is mainly composed of multi-layer filter plates and frames. Its basic working principle is to intercept impurities in the liquid through the micropores in the filter medium, thereby achieving filtration and purification of the liquid. The multi-layer plate and frame filter is usually made of corrosion-resistant materials such as stainless steel and aluminum alloy, and has high pressure resistance and stable filtering effect.

[0004] When the existing multilayer plate-and-frame filter is used to filter the injection, a large amount of impurities in the liquid medicine remain in the filter plate, and the filter plate needs to be manually disassembled for cleaning, which is extremely troublesome and inconvenient to clean. In addition, most multilayer plate-and-frame filters have rollers at the bottom and no other fixed structures, which means that the device can only be used on a flat ground, and is prone to shaking during use, and is difficult to fix on an uneven ground. As a result, the device can only be used on a flat ground, and is difficult to be used in other places of use, and has poor adaptability to the place of use. In view of this, we propose a multilayer plate-and-frame filter. Utility Model Content
