Description

Technical Field

[0001] The utility model relates to the technical field of ventilation and dust removal equipment, in particular to a sealing structure of a fan matched with dust removal equipment and the dust removal equipment. Background Art

[0002] Welding and machining are two very important and indispensable links in the fan industry. There will be a machining error in the two process links. In the field of dust removal equipment supporting fans, each fan manufacturer will have different design solutions for the two issues of sealing and vibration reduction.

[0003] At present, most manufacturers will reserve space between the fan inlet duct and the inner hole of the mounting plate to facilitate subsequent sealing and vibration reduction measures. Most manufacturers generally use sealing gaskets to seal this gap. Due to the gap problem caused by processing errors, sometimes it may be necessary to use multiple layers of sealing gaskets or even subsequent sealant to compensate for the gap. This will appear cumbersome in operation and have a poor vibration reduction effect.

[0004] Therefore, a new technology is needed to solve the sealing and vibration reduction problems in the prior art. Utility Model Content

[0007] A further technical solution of the utility model is that the e-type sealing strip is installed vertically downward through the fan air inlet, and the fan air inlet and the wall surface of the e-type sealing strip are squeezed and deformed by force to form an interference fit, thereby achieving the effects of sealing and shock absorption.

[0008] A further technical solution of the utility model is that the joint and the fixing position between the E-shaped sealing strip and the vertical ring are bonded with quick-drying glue.

[0009] A further technical solution of the utility model is that the E-type sealing strip is made of elastic material.

[0010] A further technical solution of the utility model is that there is a hollow cavity in the middle of the E-shaped sealing strip.

[0012] A further technical solution of the utility model is that the fan air inlet duct is formed into an annular structure by rolling and welding a plate material, and cooperates with the E-type sealing strip during installation to achieve a radial sealing effect.

[0013] In order to achieve the above-mentioned purpose, the utility model also proposes a dust removal device, which includes the sealing structure of the dust removal device supporting the fan as described above, which will not be described in detail here.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Please refer to Figures 1 to 7 The utility model proposes a sealing structure of a fan for dust removal equipment. The preferred embodiment of the sealing structure of the fan for dust removal equipment of the utility model includes: a fan mounting plate 4, a fan air inlet duct and an e-type sealing strip 2. The fan mounting plate 4 is provided with a vertical ring 3. There is an installation gap between the fan air inlet duct and the vertical ring 3 for installing the e-type sealing strip 2. The cross-section of the e-type sealing strip 2 is e-shaped. The e-type sealing strip 2 is provided with a notch matching the thickness of the vertical ring 3. The e-type sealing strip 2 is fixed to the vertical ring 3 through the notch.

[0029] This embodiment utilizes the elastic and easy-to-compress characteristics of the foamed E-type sealing strip 2 to reserve a reasonable gap between the fan mounting plate 4 and the fan air inlet duct. During installation, the wall surface of the E-type sealing strip 2 will be deformed under force, and the original gap fit will be changed into an interference fit, thereby achieving sealing and shock-absorbing effects.

[0030] In this embodiment, the e-shaped sealing strip 2 is made of an elastic material, such as silicone or rubber material. There is a hollow cavity in the middle of the e-shaped sealing strip 2, which can achieve a good shock-absorbing effect.

[0031] The e-shaped sealing strip 2 is installed vertically downward through the fan air inlet, and the fan air inlet and the wall surface of the e-shaped sealing strip 2 are squeezed and deformed by force to form an interference fit, thereby achieving the effects of sealing and shock absorption.

[0032] The e-type sealing strip 2 has radial compensation, which can make up for the ellipticity problem caused by processing errors. When the fan air inlet duct passes through the vertical ring 3, the wall surface of the e-type sealing strip 2 and the fan air inlet duct are compressed and deformed by force, and then form an interference fit with the surface of the fan air inlet duct. In addition, the e-type sealing strip 2 can be cut to any length to adapt to occasions of different sizes.

[0033] In this embodiment, the joints and fixing points between the e-shaped sealing strip 2 and the vertical ring 3 are bonded with quick-drying adhesive.

[0034] In this embodiment, the vertical ring 3 is formed by rolling a sheet material into a circle and then welded to the fan mounting plate 4 .

[0035] The fan air inlet duct is formed into an annular structure by rolling and welding the plate material, and cooperates with the e-type sealing strip 2 during installation to achieve a radial sealing effect.

[0036] The beneficial effects of the sealing structure of the fan supporting the dust removal equipment of the utility model are:

[0037] The utility model adopts the above technical scheme, including: a fan mounting plate, a fan air inlet duct and an E-type sealing strip, the fan mounting plate is provided with a vertical ring, an installation gap for installing the E-type sealing strip is provided between the fan air inlet duct and the vertical ring, the cross-section of the E-type sealing strip is E-shaped, the E-type sealing strip is provided with a groove matching the thickness of the vertical ring, the E-type sealing strip is fixed to the vertical ring through the groove, thereby improving the sealing and shock absorption effect of the fan supporting the dust removal equipment.

[0038] To achieve the above objectives, the utility model also proposes a dust removal device, which includes a sealing structure of the dust removal device supporting the fan as described above. The structure and working principle of the sealing structure of the dust removal device supporting the fan have been explained in detail above and will not be repeated here.
