Automatic cleaning dustless workshop purification system

Abstract

The invention relates to the technical field of air purification, and discloses an automatic cleaning dustless workshop purification system. The purification system is composed of a control system, adraught fan unit, a filter and a sensor. The filter comprises a first-level filter body, a second-level filter body and a third-level filter body. The sensor comprises a flow speed sensor and an air pressure sensor. The draught fan unit is arranged in a dustless workshop. According to the automatic cleaning dustless workshop purification system, current containing dust guided into fresh air outside is directly neutralized, floating dust can be more simply filtered, and convenience during dust filtering is improved. The threshold value is set for the flow speed of fresh air flow, and in the purification system usage process, the uniform air inlet volume and air outlet volume can be kept. When the flow speed is high or low, through adjusting of the power of the draught fan unit, the airflowflowing-in flow rate can be controlled, the proportion between the two parts is relatively balanced, and the speed is kept in a relatively stable state during purification in the workshop.

[0002] With the development of the food industry and the pharmaceutical industry, the cleanliness of the operation workshops required by the food industry and the pharmaceutical industry is getting higher and higher. However, the metabolism of the human body will produce fine dust, and the human body will carry fine dust. People are more active in the clean workshop. A large amount of fine dust will be produced and dispersed. The source of fine dust in the clean workshop, according to the analysis of the test results, the operating personnel account for about 80%, and the dust increases significantly when people enter and leave the clean workshop. The main cause of fine dust is that humans are the largest source of fine dust and the main medium of transmission in the production of medicines or food. Production personnel are always in direct or indirect contact with medicines and food, which affects the quality of medicines and food.

[0003] Therefore, it is necessary to design a purification system for the clean room to perform purification treatment on the clean room at all times. The working principle of the existing clean room purification system is that the fan unit starts to bring the fresh air from the outside to the exhaust duct, and then discharges it The incoming fresh air is filtered, and the filtered fresh air is discharged into the room for purification treatment. This purification system can only purify the clean room, and cannot monitor the flow of fresh air and air pressure inside the clean room in real time. The existing purification During the use of the system, the fan unit needs to work continuously to ensure that the workshop is always in a dust-free state. During the long-term use of the fan unit, it is affected by its own process or product quality, causing the flow rate of the airflow to not be maintained at all times. Uniform inflow, when the airflow inflow is uneven, the air pressure inside and outside the workshop will be different, causing the fresh air outside the clean room or the fresh air in the room to surge instantly, causing the purification system to filter quickly, and the fresh air will be directly introduced into the room. The air is directly discharged outside, resulting in the combination of dust-free air and dusty air, mixed in the fresh air, causing the interior of the workshop to be filled with dusty air instantly, and the dust is adsorbed on the tablets or food, making the tablets and food unable to be processed again, resulting in the Food and food waste, seriously affecting the quality of tablets and food
