Description

Technical Field

[0001] This utility model belongs to the field of FFU fan technology, and in particular relates to a new structure FFU guide frame. Background Technology

[0002] FFU stands for Fan Filter Unit, which is an air purification device that integrates a fan and a high-efficiency filtration system. It is widely used in clean rooms, clean benches, clean production lines, modular clean rooms, and local Class 100 applications.

[0003] The existing FFU airflow guide frame has internal support strips that cross in the middle, or a grid-like structure. Each side of the airflow guide frame on the air inlet surface has a reusable self-adhesive sheet. The primary filter cotton is laid flat and pasted onto the surface of the self-adhesive sheet, fixed to the air inlet surface of the FFU airflow guide frame, and plays the role of primary filtration and interception at the air inlet. The unfolded area of ​​the laid primary filter cotton is 0.354㎡. The limitation of the effective area means that the service life of the primary filter cotton in the FFU airflow guide frame is only 3 months during operation, resulting in high frequency of replacement and high replacement cost. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a novel FFU (Fan Filter Unit) guide frame, which is connected by rivets to fix and support the pleated composite mesh used for filtration, thereby increasing the unfolded area of ​​the pleated composite mesh, reducing the overall energy efficiency of the FFU, extending its service life, and reducing replacement costs.

[0005] This utility model is achieved through the following technical solution:

[0006] A novel FFU (Fan Filter Unit) airflow guide frame includes a galvanized steel frame. A supporting flat strip is provided in the middle of the interior of the galvanized steel frame. Bottom screws are installed on both sides of the lower part of the galvanized steel frame. Side baffles are integrally provided on both sides of the air inlet of the galvanized steel frame. A pleated composite mesh is provided between the two side baffles.

[0007] Preferably, the supporting flat strip and the galvanized metal frame are fixed by rivet holes.

[0008] Preferably, the side flange of the galvanized sheet metal frame has two positioning holes.

[0009] Preferably, the two positioning slots are respectively aligned with the slots of the flat strip.

[0010] Preferably, the two sides of the pleated composite cotton are inlaid and fixed between the side baffle and the galvanized metal frame.

[0011] Preferably, the material of the pleated mesh filter cotton is a composite galvanized mesh filter cotton, and the structure of the pleated mesh filter cotton is in the form of pleats, with a pleat height of 46mm and a pleat count of 31.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, the side baffle and the pleated mesh cotton increase the height of the air inlet baffle of the FFU guide frame, increase the air inlet area, and extend the service life of the primary filter cotton. Due to the low wind resistance, the overall FFU fan operates more energy-efficiently.

[0014] 2. In this utility model, the rivets and support strips are provided to support the folded and rewoven cotton. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings, as shown below. Figure 2 As shown, a new FFU airflow guide frame includes a galvanized sheet metal frame 1. A support flat strip 3 is provided in the middle of the interior of the galvanized sheet metal frame 1. Rivets 2 pass through the drilled positions for tension and fixation. Bottom screws 4 are installed on both sides of the lower part of the galvanized sheet metal frame 1. The bottom screws 4 are used to assemble and fix the galvanized sheet metal frame 1 to the FFU fan. Side baffles 5 are integrated on both sides of the air inlet of the galvanized sheet metal frame 1.

[0021] In this embodiment, specifically, the supporting flat strip 3 and the galvanized metal frame 1 are fixed by rivets 2 through holes.

[0022] In this embodiment, specifically, the side flange of the galvanized sheet metal frame 1 is provided with positioning holes, and there are two positioning holes.

[0023] In this embodiment, specifically, the two positioning gaps are respectively aligned with the gaps of the flat strip 3.

[0024] In this implementation plan, in conjunction with the appendix Figure 1 and attached Figure 3 As shown, a pleated mesh 6 is provided between the two side baffles 5.

[0025] In this embodiment, specifically, the two sides of the pleated mesh 6 are inlaid and fixed between the side baffle 5 and the galvanized metal frame 1.

[0026] In this implementation scheme, specifically, the pleated composite mesh cotton 6 is made of composite galvanized mesh filter cotton, and its structure is pleated. The semi-finished product has a pleat height of 46mm and 31 pleats. The two folds of the pleated composite mesh cotton 6, parallel to the filter cotton folds, are inserted into the fixed-fold positioning side baffles 5 on both sides of the air inlet surface for fixed support. After adjustment, the filter unfolded area is 1.66㎡, which is 4.7 times larger than the original flat area. This greatly improves the service life of the primary filter cotton.

[0027] Working principle

[0028] In this invention, the supporting flat strip 3 inside the galvanized metal frame 1 increases the effective air intake area. Simultaneously, the self-adhesive sheet pasted on the surface of the air intake metal frame is eliminated, increasing the height of the air intake baffle of the FFU guide frame. Side baffles 5 with fixed folds and positioning are added to both sides. The folded mesh cotton 6 significantly increases the air intake area, extends the service life of the primary filter cotton, reduces wind resistance, and contributes to energy saving in the overall FFU fan operation. However, the folded mesh cotton 6 and the semi-finished product folding process increase the product cost in the short term, thus increasing the unfolded area of ​​the primary filter cotton.

[0029] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution of this utility model, falls within the protection scope of this utility model.
