Automatic door double-opening cargo shower chamber

The automatic door double-opening cargo air shower is a local purification device used to transition between clean and non-clean areas. It is mainly used to blow and purify the goods entering the clean room to remove dust, impurities, and other impurities on the surface of the goods and reduce the pollution in the clean room. The following is a detailed introduction to it:
Structure and Principle
Structural composition: It is mainly composed of a box body, automatic sliding double doors, air shower nozzles, purification fans, filtration systems, control systems, lighting systems, and other components. The box body is typically made of cold-rolled steel plates with an inner and outer thickness of 1.2 mm and features baked paint. It can also be made of SUS304 or SUS201 stainless steel with an inner and outer thickness of 1.2mm. The automatic sliding double doors are made of all stainless steel (SUS304) and are equipped with 3C-certified tempered glass Windows. The air shower nozzles are generally 360-degree rotatable embedded installation mirror-finish stainless steel nozzles. Most purification fans are dedicated purification centrifugal low-noise fans. The filtration system adopts three-stage filtration, including medium and low-efficiency pre-filters and high-efficiency filters. The control system is generally a PLC control system, equipped with a touch LCD panel control switch.
Working principle: When the goods enter the infrared sensing area, the PLC automatic control system of the automatic door double-opening goods shower room receives the signal, and the door automatically opens to both sides, allowing the goods to enter the goods shower room. At this point, the system initiates the air shower program. The purification fan sprays the clean air filtered by the filtration system from all directions onto the surface of the goods through the air shower nozzles to remove dust and impurities. After the air shower is completed, the other side door opens automatically and the goods can enter the clean room.
Characteristics and Advantages
High degree of automation: It adopts a PLC automatic control system, achieving a series of operations such as automatic induction door opening, air shower, and door closing, without the need for manual intervention. This improves work efficiency and reduces the contamination of the clean room by human factors.
Excellent air shower effect: Double-sided air blowing, the air shower nozzles can rotate 360 degrees, allowing for air showering on the goods from different angles to ensure that dust and impurities on the surface of the goods are thoroughly removed. Meanwhile, the air shower speed can reach 25-30m/s, and the high wind speed ensures the air shower effect.
Good sealing performance: The double doors are smooth, firm, and aesthetically pleasing when combined with the door frame. Sealing measures such as sealing strips are adopted, effectively preventing the entry of outside air and ensuring the cleanliness of the goods shower room.
Safe and reliable: It is equipped with a red "emergency stop" button inside. In an emergency, when the button is pressed, the system will be powered off and both doors can open simultaneously, facilitating the escape of personnel. In addition, it also features functions such as door lock protection and fault display to ensure the safe operation of the equipment.
Application field
The electronics/microelectronics industry, such as semiconductor manufacturing and electronic component production, has extremely high requirements for the cleanliness of the production environment. The automatic door double-opening cargo shower can effectively remove dust and impurities on the surface of goods, preventing contamination of electronic components.
In the biomanufacturing industry: including pharmaceuticals, biological product manufacturing, etc., to ensure the quality and safety of products, it is necessary to strictly control the cleanliness of the production environment. The goods shower room can prevent contaminants brought in by goods from affecting the production process.
In the food processing industry, especially for some food production enterprises with high hygiene requirements, such as dairy products and baked goods, the automatic door double-opening cargo shower can prevent the dust and bacteria carried by the goods during transportation from entering the production workshop, ensuring the hygiene and safety of the food.
The liquid crystal and optoelectronic display industry: In fields such as liquid crystal panel manufacturing and optoelectronic product production, a clean production environment is crucial for the quality and performance of products. The cargo shower can ensure that the goods entering the clean room meet the cleanliness requirements.
Maintenance and upkeep
Regular cleaning: Regularly clean the interior and exterior of the goods shower room to remove dust, dirt, and debris. Especially for components such as air shower nozzles and filters, it is necessary to ensure that their surfaces are clean to avoid affecting the air shower effect and filtration efficiency.
Filter replacement: Regularly replace the medium and low-efficiency pre-filters and high-efficiency filters based on the usage frequency and environmental conditions. Generally speaking, the medium and low-efficiency pre-filters should be replaced every 1 to 6 months, and the high-efficiency filters every 6 to 12 months to ensure the filtration effect and airflow.
Fan inspection: Regularly check the operation of the purification fan, including the fan's rotational speed, air volume, noise, etc. If any abnormal operation of the fan is found, it should be repaired or replaced in time.
Electrical system inspection: Check the working conditions of electrical components such as the PLC control system, touch LCD panel, photoelectric switch, and door lock to ensure their normal operation. If any malfunction is found, it should be eliminated in time to avoid affecting the normal use of the goods shower room.
