Description

Technical Field

[0001] The utility model relates to the technical field of film package processing, in particular to a film package clamp for automatic loading and unloading. Background Art

[0002] In order to solve the defect that the traditional dead-end filtration method will cause the rapid accumulation of filter cake layer and gel layer, resulting in a decrease in filtration efficiency, more and more production processes adopt tangential flow filtration. Compared with traditional dead-end filtration, tangential flow filtration can form shear on the membrane surface during the filtration process, which plays a flushing role and effectively alleviates the accumulation of large particles and molecules on the membrane, reduces the generation of filter cake layer and gel layer, and ensures a stable flow rate. Therefore, it has a higher and more stable flow rate and high production efficiency.

[0003] Existing membrane package clamps, such as a one-way tangential flow membrane package clamp disclosed in a Chinese patent (publication number: CN219922601U), include at least one connecting plate, which is sandwiched between two adjacent membrane packages. The connecting plate is provided with a first contact surface in contact with the upper membrane package and a second contact surface in contact with the lower membrane package. The first contact surface is provided with a filtrate inlet and a feed liquid inlet, and the second contact surface is provided with a filtrate outlet and a feed liquid outlet. The feed liquid inlet is located on the side opposite to the feed hole of the adjacent first clamp plate or the feed liquid outlet of the adjacent connecting plate. The filtrate inlet is located on the side opposite to the feed hole of the adjacent first clamp plate or the feed liquid outlet of the adjacent connecting plate. It is connected to the filtrate outlet, the feed liquid inlet and the feed liquid outlet are connected, and each level of membrane package is connected in series by the flow plate. The feed liquid that cannot pass through the filter membrane in the previous level of membrane package can pass through the filter membrane in the next level of membrane package, which is beneficial to improving the conversion rate of the feed liquid. However, in actual production, when using this type of membrane package clamp, manual operation is required to replace the membrane package, which is time-consuming and laborious. At the same time, when replacing the membrane package, the operator arbitrarily touches the dye liquid, which has certain safety hazards, and the feed liquid remaining between the clamps will also flow into the filtrate, causing filtrate contamination, requiring additional cleaning work to be performed manually during each replacement.
