Description

Technical Field

[0001] This utility model relates to an isolator insulation structure. Background Technology

[0002] An isolator is a device used in pharmaceutical manufacturing to provide a suitable background environment for drug production. It isolates the drug production area from the external environment to maintain relatively independent and specific environmental conditions that meet the requirements of drug production, ensuring that the drug production process is not disturbed or contaminated by external factors.

[0003] Isolators provide a suitable background environment for drug production, and different drugs require different background environments. Temperature is a crucial indicator of the background environment, and while it can be regulated by the isolator's air conditioning system, existing systems are insufficient for situations with significant temperature differences between the inside and outside of the isolator. To overcome these shortcomings, improvements to the existing isolator structure are necessary.

[0004] Therefore, an isolator insulation structure is proposed to address the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the existing defects and provide an isolator insulation structure that can ensure that the internal temperature of the isolator meets the temperature requirements of the pharmaceutical production environment under various extreme background environments.

[0006] The technical solution to achieve the above objectives is: an isolator insulation structure, including a return air duct, a cavity, a fan casing, an air duct, an air duct maintenance cover, and a static pressure box cover;

[0007] The side of the cavity is connected to the return air duct; the upper end of the cavity is connected to the fan housing, the upper end of the fan housing is connected to the air duct, and the side wall of the air duct is connected to the air duct maintenance cover; the static pressure box cover is connected to the static pressure box equipment.

[0008] The return air duct, the cavity, the fan casing, the air duct, the air duct maintenance cover, and the static pressure box cover are all equipped with heat insulation components.

[0009] Preferably, the return air duct includes an outer shell and an inner shell, and the insulation component includes a first insulation cotton, which is filled between the outer shell and the inner shell.

[0010] Preferably, the insulation component further includes a second insulation cotton, which fills the hollow space inside the cavity.

[0011] Preferably, the fan housing includes a fan outer shell and a fan inner shell, and the insulation component further includes a third insulation cotton, which is filled between the fan outer shell and the fan inner shell.

[0012] Preferably, the air duct includes an outer shell and an inner shell, and the insulation component further includes a fourth insulation cotton, which is filled between the outer shell and the inner shell.

[0013] Preferably, the duct maintenance cover includes a U-shaped plate and a flat plate, which are welded together; the insulation component further includes a fifth insulation cotton; the fifth insulation cotton is filled between the U-shaped plate and the flat plate.

[0014] Preferably, the static pressure chamber cover plate includes an outer cover plate and an inner cover plate, and the insulation component further includes a sixth insulation cotton, which is filled between the outer cover plate and the inner cover plate.

[0015] The beneficial effects of this utility model are: the insulation structure of this isolator, by setting insulation components in the return air duct, cavity, fan casing, air duct, air duct maintenance cover and static pressure box cover, can prevent excessive heat conduction between the inside and outside of the isolator, thereby solving the problem of large temperature difference between the inside and outside of the isolator and the inability of air conditioning to control the temperature; it can still ensure that the internal temperature of the isolator meets the temperature requirements of the pharmaceutical production environment under various extreme background environments.
