Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of purification equipment, in particular to a laminar flow transfer cart. Background Art
[0002] The laminar flow transfer cart is a purification equipment in a clean room, providing a self-circulating clean microenvironment. It is a special supporting equipment in the clean purification industries such as pharmaceuticals and electronics, and realizes the transfer of raw materials, semi-finished products and finished products in a sterile environment. Under the action of laminar flow, the air flow will not affect the transferred items, and the air flow outside the transfer cart space will not enter the transfer cart space. Generally, the items to be transferred are usually sterilized and then transferred into the laminar flow transfer cart under the protection of laminar flow. During the transfer process, a laminar flow hood is often installed above the transfer path or a laminar flow transfer cart is used. However, in the use process, there are problems whether a laminar flow hood is installed or a laminar flow transfer cart is used:
[0003] (1) The cost of installing a laminar flow hood is relatively high. Setting too many laminar flow hoods on the transfer path will affect the space layout, and the heat generated during the operation of the laminar flow hood will even affect the temperature control of the clean room, resulting in unnecessary cost consumption.
[0004] (2) Generally, when using a laminar flow transfer cart, the sterilized items need to be manually transferred into the laminar flow transfer cart under the laminar flow hood first, and then transferred to the use point and then to the working interface under the laminar flow state. Although this method has less installation cost of the laminar flow hood and relatively flexible transfer, it requires manual operation during the transfer process, which is likely to cause item contamination.
