Description

Technical Field

[0001] This utility model relates to the field of ventilation and dust removal equipment technology, and in particular to a matching fan and dust removal equipment for a dust removal device. Background Technology

[0002] Welding and machining are two crucial and indispensable processes in the fan industry. However, a machining error can occur in these two processes. For example, CN222772373U discloses a sealing structure for a dust removal equipment's matching fan and the dust removal equipment itself. It discloses sealing through a sealing ring with an E-shaped cross-section. However, during machining, because the fan mounting plate and the fan inlet duct are machined independently, high-precision fit cannot be guaranteed. This leads to axial deviation during installation, causing the duct to tilt to one side of the vertical cylinder, resulting in one side compressing the sealing ring and the other side having a gap, resulting in poor sealing. Therefore, this utility model proposes a matching fan and dust removal equipment to solve the problems existing in the prior art. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this utility model is to propose a matching fan and dust removal equipment for a dust removal device. By setting a double-layer reinforcing ring filled with sealant, the matching fan and dust removal equipment can fit tightly against the bottom of the air inlet cylinder during installation. The spacing between the two sets of concentric rings of the double-layer reinforcing ring can better address the problem of misalignment between the air inlet cylinder and the axis of the double-layer reinforcing ring due to separate and independent processing, resulting in better sealing after the fan is installed.

[0004] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a fan for a dust removal device, including a fan base plate, a double-layer reinforcing ring, sealant, sealing film, mounting mechanism, fan frame, and inlet cylinder. The upper side of the fan base plate is fixedly provided with a double-layer reinforcing ring, the inner side of the double-layer reinforcing ring is a through-hole structure, the double-layer reinforcing ring is composed of two sets of coaxially arranged rings and the space between the rings is filled with sealant, and a sealing film is provided between the upper sides of the two sets of rings of the double-layer reinforcing ring. The fan frame is provided on the fan base plate through the mounting mechanism, and an inlet cylinder is provided on the lower side of the fan frame. The lower end of the inlet cylinder is inserted into the space between the two sets of rings of the double-layer reinforcing ring for adaptation, and its lower end is inserted into the sealant to form a sealed adaptation structure. The space between the two sets of rings allows for a larger range of deviation between the inlet cylinder and the double-layer reinforcing ring.

[0005] A further improvement is that the sealant fills 70%-80% of the height of the space between the two sets of circular rings of the double-layer reinforcing ring.

[0006] A further improvement lies in that: due to the presence of the sealing film, the sealant filled in the circular ring spacing of the double-layer reinforcing ring is in an uncoagulated state. When installing, inserting the lower end of the air inlet cylinder into the gap of the double-layer reinforcing ring will damage the sealing film, and the lower end of the air inlet cylinder will be inserted into the sealant. After the sealing film is damaged, the sealant gradually coagulates after contacting the air to achieve a sealed wrapping of the lower end of the air inlet cylinder.

[0007] A further improvement lies in that: the installation mechanism includes installation bolts, circular rubber gaskets, single-sided rubber washers and installation nuts. The installation bolts are symmetrically arranged on the fan bottom plate. Circular rubber gaskets are arranged above the installation bolts, and there are two groups of circular rubber gaskets arranged up and down. The installation bolts pass through the fan frame and are provided with circular rubber gaskets. The circular rubber gaskets pass through the lower end of the fan frame and are adapted to the circular rubber gaskets on the upper side. An installation nut is provided at the end of the installation bolt at the upper end of the circular rubber gasket for fastening.

[0008] A further improvement lies in that: a driving motor is arranged above the fan frame, and fan blades are arranged in the fan frame. The fan blades are connected to the output end of the driving motor.

[0009] A dust removal device, which includes a supporting fan for the above-mentioned dust removal device.

[0010] The beneficial effects of the present utility model are as follows: by arranging sealant filled in the double-layer reinforcing ring, it can closely fit the lower part of the air inlet cylinder during installation. The spacing between the two concentric circular rings of the double-layer reinforcing ring can better cope with the problem of the axis offset between the air inlet cylinder and the double-layer reinforcing ring caused by separate independent processing, making the sealing performance of the fan better after installation.

[0014] To deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. These embodiments are only used to explain the present utility model and do not constitute a limitation to the protection scope of the present utility model.

[0015] According to Figure 1 and Figure 2As shown, this embodiment provides a matching fan for a dust removal device, including a fan base plate 1, a double-layer reinforcing ring 2, sealant 3, sealing film 4, a mounting mechanism, a fan frame 5, and an air inlet cylinder 6. The double-layer reinforcing ring 2 is fixedly installed on the upper side of the fan base plate 1. The inner side of the double-layer reinforcing ring has a through-hole structure. The double-layer reinforcing ring 2 is composed of two sets of coaxially arranged rings, and the space between the rings is filled with sealant 3. A sealing film 4 is provided between the upper sides of the two sets of rings of the double-layer reinforcing ring 2. The fan frame 5 is installed on the fan base plate 1 through the mounting mechanism. The air inlet cylinder 6 is provided on the lower side of the fan frame 5. The lower end of the air inlet cylinder 6 is inserted into the space between the two sets of rings of the double-layer reinforcing ring 2 for adaptation. Its lower end is inserted into the sealant to form a sealed adaptation structure. The space between the two sets of rings allows for a larger range of deviation between the air inlet cylinder and the double-layer reinforcing ring, avoiding the phenomenon of one side being sealed and the other side having a gap.

[0016] The sealant 3 fills 70%-80% of the height of the space between the two sets of circular rings of the double-layer reinforcing ring 2.

[0017] The sealant 3 filled in the annular space of the double-layer reinforcing ring 2 is in an uncured state due to the presence of the sealing film 4. When the lower end of the air inlet cylinder 6 is inserted into the gap of the double-layer reinforcing ring 2 during installation, the sealing film 4 will be damaged, and the lower end of the air inlet cylinder 6 will be inserted into the sealant 3. After the sealing film 4 is damaged, the sealant 3 will gradually solidify after contact with air, thus sealing and wrapping the lower end of the air inlet cylinder 6.

[0018] The inner surface of the double-layer reinforcing ring can also be coated with an anti-stick coating, which facilitates the disassembly and maintenance of the fan frame later. After disassembly, the solidified sealant is taken out together with the air inlet cylinder. During installation, the sealant is also tightly attached to the inner space of the double-layer reinforcing ring.

[0019] The mounting mechanism includes mounting bolts 7, circular rubber pads 8, single-sided rubber washers 9, and mounting nuts 10. Mounting bolts 7 are symmetrically arranged on the fan base plate 1. Circular rubber pads 8 are arranged on the upper side of the mounting bolts 7. There are two sets of circular rubber pads arranged at the top and bottom. The mounting bolts 7 pass through the fan frame 5 and are fitted with the circular rubber pads 8. The circular rubber pads pass through the lower end of the fan frame and are adapted to the upper circular rubber pads. Mounting nuts 10 are provided at the end of the mounting bolts 7 at the upper end of the circular rubber pads 8 for fastening.

[0020] A drive motor 11 is installed on top of the fan frame 5, and fan blades 12 are installed in the fan frame 5. The fan blades 12 are connected to the output end of the drive motor 11.

[0021] A dust removal device, including the aforementioned dust removal device's matching fan, the effects and principles of which have been described in detail and will not be repeated here.
