Problems solved by technology

There are many dusty and humid problems in these dangerous environments. Due to poor sealing and insufficient protection, conventional fans are prone to dust or water vapor entering the motor, which will lead to motor damage and safety problems, and the existing fans are in use. During the process, the casing will vibrate, which will not only generate a lot of noise, but also easily cause deformation and even damage of the casing, and most of the existing fans and support frames are fixed by bolts, which is not only easy to occur in a vibrating environment Loose, and it is difficult to disassemble and install the support frame, which is inconvenient to use

Embodiment 1

[0040] See Figure 1-9 , A safety-type noise-proof explosion-proof fan of a dust-proof waterproof steam according to an embodiment of the present invention, including a housing 1, and a cylinder 2 is secured by a plurality of first connecting rods 43, the circle A circular hole 3 is provided at one end of the cartridge 2, and the cylinder 2 is fixedly provided with a motor 4 by a plurality of second connecting rods 44, and the rotation shaft of the motor 4 extends through the circular hole 3, said The shaft of the motor 4 extends out of the cylinder 2 fixed to a fan blade mount 5, and the outer wall of the mounting seat 5 is fixedly provided with a plurality of blades 6, and the inner wall of the circular hole is fixedly embedded. Circle 7, and the O-type seal ring 7 is closely fit to the rotation shaft of the motor 4, and the motor 4 is spirally wrapped around the heat absorbing tube 8, the cylinder 2 away from the round hole 3 ends There is a cyclic cartridge 9, and there is a ring...

Embodiment 2

[0043] See Figure 1-2 For housing 1, the outer walls of the housing 1 are fixed in a sleeve arrangement with a flange 36, and the flange 36 has several mounting holes in the circumferential direction, and for the motor 4, The rotating shaft of the motor 4 extends out of the middle outer wall fixing sleeve of the cylindrical 2, and the baffle 37 is disposed from the cylindrical 2 to a curved structure.

[0044] According to the above scheme of the present invention, the flange plate 36 and the mounting hole can facilitate the connection of the housing 1 and the venting conduit, and the baffle 37 can further prevent impurities such as dust or water from entering the cylinder 2 from the circular hole 3, and The baffle 37 is provided with a circular arc structure to reduce the resistance of the baffle 37 on the airflow.

Embodiment 3

[0046] See figure 1 , 5 And 8, for the fan blade mount 5, the fan leaf mount 5 is a circular stage structure, and the fan leaf mount 5 is fixedly provided with a cone 38 at one end of the motor 4; for button 24 The outer wall of the button 24 is fixedly provided with a silica gel pad 39.

[0047] With the above scheme of the present invention, the cone 38 can effectively reduce the resistance of the airflow of the fan blade mount 5, and the silica pad 39 can effectively increase the comfort of the pressing button 24.

Abstract

The invention discloses a dust-proof, water-proof and safe noise-reducing explosion-proof fan, which comprises a housing, and a cylinder is fixed inside the housing through a plurality of first connecting rods, and a circular hole is opened at one end of the cylinder. A motor is fixed inside the cylinder through a number of second connecting rods, the rotating shaft of the motor extends out of the cylinder through the circular hole, and the rotating shaft of the motor extends out of the cylinder and one end is fixedly equipped with a fan blade. The outer wall of the fan blade installation seat is fixed with a number of fan blades. Beneficial effects: the motor can be effectively isolated from the external environment, thereby effectively preventing dust, water vapor and other substances in the harsh environment from entering the motor to cause damage to the motor and safety problems, and the shell can be effectively damped, thereby being able to The casing is protected, the noise generated by the vibration of the casing is reduced, and the assembly and disassembly of the casing and the slide bar can be facilitated, thereby greatly increasing the convenience of use.

Description

Technical field [0001] The present invention relates to the field of explosion-proof fan, and in particular, there is a safety-type noise-proof explosion-proof fan of dust-proof and waterproof steam. Background technique [0002] The fan is a mechanical for compression and delivery gas, from an energy point of view, which is a mechanical to convert the mechanical energy of the original motivation into gas energy. The centrifugal fan is mainly composed of major components such as venting, impeller, and volute, and is generally used in indoor ventilation of large buildings such as factory. Other situations, mainly using the centrifugal force generated by the impeller to obtain energy, and then converted to a static pressure via a volute and a volute outlet diffusion section. The types of common centrifugal fan delivery gases are air or other non-flammable, non-corrosive gas, non-corrosive gas. [0003] The explosion-proof fan is mainly suitable for buildings in indoor ventilation a...
