Description

Technical Field

[0001] The utility model belongs to the technical field of air dehumidification, and in particular relates to a plate-type and bag-type integrated filter frame structure. Background Art

[0002] Bag filter is one of the important components of rotary dehumidifier units, air dehumidifier units, air handling units, dehumidifying air conditioning units, and constant temperature and humidity units. However, when used in high-pollution industries such as food and casting, it is necessary to add a plate filter before the bag filter as a pretreatment. The highly polluted air is first filtered by the plate filter and then deeply filtered by the bag filter. A 500-600mm filter replacement and maintenance space is left between the two filters.

[0003] The commonly used installation structure in the manufacturing process of rotary dehumidifier units, air dehumidifier units, air handling units, dehumidification air conditioning units, and constant temperature and humidity units is to make an installation frame corresponding to the filter frame size, and then fix the installation frame in the corresponding filter function section partition of the unit, and the filter function section partition is fixed inside the chassis of the unit; the filter installation frame will be made into standard size frames according to some standard filter size specifications as inventory, and the filter installation frame of the corresponding size specification will be called up for use according to the production needs of the unit.

[0004] During the manufacturing process of some non-standard units in special occasions, if the standard filter cannot meet the performance requirements of the unit, the filter needs to be resized. In this case, the standard filter mounting frame cannot meet the requirements. At this time, the filter mounting frame needs to be remade, which prolongs the production time.

[0005] The cost of manufacturing a standard filter mounting frame is relatively high. Due to the overlapping use of sheet metal, the filter mounting frame must be reinstalled within the filter section partition, requiring repeated installation time. This structure also contributes to the high cost. The standard filter mounting frame inevitably creates some unresolvable joints during installation, which can lead to a loss of bag filtration efficiency within the filter section. The space required for replacement and maintenance between the two filter sections increases the length of the unit, significantly increasing the overall manufacturing cost of the equipment.

[0006] Chinese patent publication number CN219518220U discloses an installation structure for a side-drawn plate-bag combination air filter. It includes a side-drawn filter assembly, used to filter air from a ship's air conditioning unit, comprising a plate filter and a bag filter connected in sequence; a fresh air refrigeration assembly, used to deliver air to the ship's air conditioning unit and cool and dehumidify it, comprising a fresh air inlet, a cooling coil, a water baffle, and a fan; filter slides are provided on the side of the air conditioning box of the ship's air conditioning unit, and the filter slides are installed on both sides of the side-drawn filter assembly; a water baffle is provided between the cooling coil and the fan, and a refrigeration circulation pipe is installed on the cooling coil. The plate filter, bag filter, and filter slide eliminate the need for a mixing box, reducing the length of the unit, minimizing installation space, and saving manufacturing costs.

[0007] The above patent solution only allows the installation of plate filters and bag filters at the same time. However, in different usage environments, the requirements for the use of filters are different. Although the use of both filters can increase the filtering effect, the cost will increase and the ventilation efficiency will decrease. For example, the different production tasks in the usage scenario will change the requirements for the use of filters. For example, only a single plate filter or bag filter is required, or a plate filter and bag filter are used at the same time. The above patent solution obviously cannot meet the usage requirements.
