Working principle of automatic double cargo shower
Working principle of automatic double cargo showerThe working principle of the automatic double-open shower is like a carefully choreographed purification "dance", where each step is closely connected and precise.When the goods are near the cargo shower, the high-precision infrared sensor installed at the entrance, like a sensitive "small guard", quickly captures the arrival of the goods and immediately transmits the signal to the control system. The control system is like the "brain" of the cargo shower, after receiving the signal, it quickly reacts and sends the command to the automatic door drive device. After receiving the instruction, the automatic door drive device, like a soldier receiving a charging horn, immediately begins to work, driving the automatic door to open smoothly and quickly to both sides to greet the entry of goods. After the goods enter the cargo shower, the infrared sensor plays a role again, and the signal is fed back to the control system after the goods are detected. The control system then issues the closing instruction, and the automatic door slowly closes, completely isolating the shower room from the outside environment, and creating a relatively closed space for the subsequent purification of the shower. Then, the shower system starts, which is the core link of the entire workflow. The high-power fan begins to operate, and the surrounding air is sucked into the primary filter. The initial effect filter is like a "big net", which can filter out large dust particles in the air, such as hair, debris, etc., to reduce the burden for subsequent efficient filtration. After the initial filtering of the air, into the plenum, in the plenum, the air is evenly distributed in preparation for entering the HEPA filter. The HEPA filter is the "trump weapon" of the blow-off system, which can deeply filter the air and remove tiny dust particles and bacteria. The clean air filtered by the high-efficiency filter is sprayed out of the multi-angle nozzle at a wind speed of up to 25m/s or more. These nozzles are like a "small nozzle", which is cleverly arranged on the top and side of the cargo shower room and can blow to the surface of the goods in an all-round way and without dead corners. The high-speed jet of clean air, like a hard-working "cleaning small expert", quickly and effectively blows down the dust particles, bacteria, and other pollutants attached to the goods. Blown dust particles and air-carrying pollutants will not be freely dispersed in the cargo shower. They will be attracted by the negative pressure generated by the fan and re-enter the primary effect filter and high-efficiency filter for filtration. This filtration cycle process is like a constantly running "purification factory", which continuously cleans the air in the shower room to ensure the continuity and stability of the blowing effect. When the blowing time reaches the preset value, the control system will issue an instruction to stop the operation of the blowing system. At the same time, the automatic door drive device is instructed again to open the door on the other side, and the goods can leave the cargo shower and enter the clean room. During the entire process, the two doors of the automatic double-opening cargo shower room are always electronically interlocked to ensure that only after one side door is completely closed, the other side door can be opened, effectively preventing unpurified air from entering the clean room. |
