Description

Technical Field

[0001] The utility model relates to the technical field of ventilation devices, in particular to a highly integrated quick-change filtering ventilation device. Background Art

[0002] Currently, the dust filters, air inlet shut-off valves, filter absorbers, air volume measurement components, and fans in the filtration and ventilation devices used are basically discretely distributed structures. The various components need to be connected into a whole using multiple sections of ventilation ducts. This has disadvantages such as high system air flow resistance, many installation joints, and large space occupation. At the same time, the fine filter unit and the gas filter unit cannot be replaced individually. After use in a contaminated environment, the filter absorber needs to be replaced as a whole, resulting in low product utilization and high usage costs. How to achieve the miniaturization and integration of the structure of filtration and ventilation devices, as well as the rapid replacement of fine filter units and gas filter units, has always been a technical bottleneck for the entire industry and needs to be solved urgently. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the overall structure of the device occupies a large area, the product utilization rate is low and the cost is high.

The poison filter unit is mounted on the outside of the fine filter unit, and the inside of the fine filter unit is connected to the air inlet channel in the shell.

[0005] Preferably, the fine filtration unit includes a cylindrical metal frame and a paper core sleeved on the outside of the metal frame, the outside of the metal frame is provided with crisscross reinforcing ribs, and the paper core is fastened to the metal frame by bolts.

[0006] Preferably, a cylindrical mounting structure is fixedly installed on the inner top of the shell, an air inlet closing valve is installed on the inner top of the mounting structure, an air volume measurement component is installed on the inner bottom of the mounting structure, and the mounting structure is located at the inner top of the fine filter unit.

[0007] Preferably, the poison filtering unit includes a cylindrical cavity structure, the inner layer of the cylindrical cavity structure is filled with adsorption material, and air inlet holes are provided on the inner and outer sides of the cylindrical cavity structure.

[0008] Preferably, a lower sealing gasket and an upper sealing gasket are installed on the inner bottom and inner top of the shell respectively, and the top and bottom of the fine filter unit and the poison filter unit are respectively abutted against the upper sealing gasket and the lower sealing gasket.

[0009] Preferably, the bottom of the housing and the fan are both mounted on the base by bolts, and the top of the fan is connected to the top of the housing by an L-shaped fan connector.

[0010] Preferably, the air outlet is connected to the air inlet of the fan via a rubber hose, which is fixed by a clamp.

[0011] This utility model provides a highly integrated, quick-change filter-ventilation device for use in gas-filtering ventilation systems for mobile platforms, vehicle-mounted shelters, and laboratories. The system's air supply duct is securely connected to the dust filter's air inlet. During operation, the air inlet shutoff valve and fan are opened, allowing contaminated air to pass sequentially through the dust filter, fine filter unit, and gas filter unit. The dust filter removes large dust particles from the contaminated air, while the fine filter unit and gas filter unit remove small dust particles, radioactive fallout, chemical agents, and biological warfare agent aerosols. The resulting clean air is then delivered to the protected space via the fan, meeting the living and working needs of personnel within.
