Description
Technical Field
The utility model relates to an air purification technical field, in particular to filter formula FFU of tearing open soon.
Background
The FFU is called a Fan Filter Unit (Fan Filter Unit) in English, and the Chinese special language is a Fan Filter Unit. But FFU fan filter screen unit modularization connects the use, uses FFU wide application in application occasions such as toilet, clean workbench, clean production line, assembled toilet and local hundredth level.
The existing filter and filter frame are produced separately and independently, the filter is installed in the filter frame after being made into finished products, the filter and the outer frame of the filter are assembled and then placed under an FFU box body, the filter unit is sealed by the dead weight of the FFU box body, and the sealing performance is poor. When the filter is replaced, the FFU box body needs to be taken down, so that the filter can be taken out from the outer frame of the filter, and the operation is inconvenient.
Therefore, there is a need for an improved filter mounting structure to simplify the disassembly process.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a main aim at provides a filter formula FFU that tears open soon can conveniently tear open the washing to miniature air purification equipment's filter.
The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides a filter formula FFU that tears open soon, includes the box, be equipped with the fan in the medial surface of box, the filter is installed to the lateral surface of box, the filter is fixed in fixed frame, the box is equipped with fixed platform in the edge of lateral surface, the last a plurality of rivet nuts that are equipped with of fixed platform, it is fixed with rivet nut to wear to be equipped with a plurality of bolts on the fixed frame.
Specifically, the fixed frame is a square tube with a rectangular cross section.
Furthermore, a first sealing gasket is clamped between the fixed platform and the fixed frame.
Further, the box is provided with an inner turnover face on the edge of the outer side face, the fixed frame is provided with an outer boss, and a second sealing gasket is clamped between the outer boss and the inner turnover face.
Specifically, the filter is a high-efficiency filter screen.
The utility model discloses technical scheme's beneficial effect is:
this equipment saves and tears down the aluminium frame open, has optimized the product structure, has simplified the equipment flow, has reduced the cost of manufacture and the labour cost of filter unit, lets subsequent maintenance, maintenance and change need not to take off FFU box alright operation.

Detailed Description
The present invention will be described in further detail with reference to specific examples.
Example (b):
as shown in fig. 1 and 2, the utility model discloses a filter formula FFU that tears open soon, including box 1, be equipped with fan 2 in the medial surface of box 1, filter 3 is installed to the lateral surface of box 1, and in filter 3 was fixed in fixed frame 4, box 1 was equipped with fixed platform 11 in the edge of lateral surface, was equipped with a plurality of rivet nuts 12 on the fixed platform 11, wears to be equipped with a plurality of bolts 5 on the fixed frame 4 and fixes with rivet nuts 12. The fixed platform 11 faces the outside of the outer side face, and the blind rivet nut 12 provides a screw fixing position of the bolt 5 on the fixed platform 11. When the fixing frame is installed, the fixing frame 4 only needs to be tightly attached to the fixing platform 11 and then is fixed by the bolt 5 through applying force from the front side of the outer side face, and the aluminum frame is omitted to be disassembled. This equipment has optimized the product structure, has simplified the equipment flow, has reduced the cost of manufacture and the labour cost of filter unit, lets subsequent maintenance, maintenance and change need not to take off FFU box alright operation.
As shown in fig. 2, the fixed frame 4 is a square tube having a rectangular cross section. Therefore, the fixed frame 4 has light weight in unit length and firm structure, and can be conveniently punched by the bolt 5.
As shown in fig. 2, the first gasket 6 is sandwiched between the fixed platform 11 and the fixed frame 4. The first gasket 6 is used to block the joint between the housing 1 and the filter 3, and prevent air from directly entering the housing 1 without being filtered through the filter 3.
As shown in fig. 2, the case 1 is provided with an inner-turned surface 13 on the edge of the outer side surface, the fixed frame 4 has an outer boss 41, and the second gasket 7 is sandwiched between the outer boss 41 and the inner-turned surface 13. The second packing 7 also holds the joint between the case 1 and the filter 3, and improves the sealing performance by being combined with the first packing 6.
The filter 3 is a high-efficiency filter screen. The high-efficiency filter screen can effectively filter out granular impurities in the air.
What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
