Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a glass fiber reinforced plastic fan and a mounting base. Background Art

[0002] Waste gas treatment, also known as waste gas purification, refers to the treatment of waste gas generated in special scenarios such as industrial sites and factory workshops before it is discharged to the outside, so that the waste gas discharged to the outside can meet national emission standards and reduce pollution to the environment.

[0003] In the process of treating exhaust gas, a glass fiber reinforced plastic fan is needed to transport the exhaust gas so that the exhaust gas can be processed through multiple links to meet the emission standards. At present, when transporting the exhaust gas, the fan used cannot pre-treat the exhaust gas, which makes the later gas purification equipment treat the exhaust gas. The service life of the dust filter element in the equipment is greatly shortened, and the fan will generate certain vibrations during operation, which will cause damage to the fan during long-term use. Therefore, we propose a glass fiber reinforced plastic fan and mounting base to solve the above-mentioned problems. Utility Model Content

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Example 1

[0036] Reference Figure 1-4 A fiberglass reinforced plastic fan comprises a fan base 1, to the top of which is mounted a fan duct 2 via bolts or other fixing means. The shape and size of the duct 2 are designed according to specific needs to ensure smooth gas flow. A butt-joint pipe 3 is fixedly mounted on one side of the duct 2 for connecting to an external pipeline or other equipment to facilitate gas transportation.

[0037] A blade mechanism is installed on the other side of the wind tube 2. The blade mechanism specifically includes a rotating ring 4 that is rotatably connected to the other side of the wind tube 2. The rotating ring 4 is connected to the wind tube 2 via a bearing or other rotating connection method to ensure that it can rotate smoothly. A rotating shaft is installed at the center position of one side of the rotating ring 4 by welding or other fixing methods. Multiple groups of axial flow blades 5 are fixed to the rotating shaft. The shape and number of the axial flow blades 5 are designed according to specific needs to ensure that sufficient suction is generated. One side of the rotating shaft extends into the wind tube 2 and is rotatably connected to the inner wall of the wind tube 2 through a bracket. The rotating ring 4 is connected to the power mechanism.

[0038] Specifically, the left side of the rotating ring 4 is rotatably connected to the right end of the wind tube 2 through a bearing. The left side of the rotating ring 4 is fixed with a rotating shaft, and multiple groups of axial flow blades 5 are fixed on the rotating shaft. The axial flow blades 5 can be welded and fixed to the rotating shaft, or welded and fixed on the clamp, and the clamp is fixed to the rotating shaft by bolts. In order to maintain the stable operation of the blade mechanism, at least one bracket can be set inside the wind tube 2. The center of the bracket is rotatably connected to the rotating shaft through a bearing, and the end of the bracket is fixedly connected to the inner wall of the wind tube 2.

[0039] The power mechanism specifically includes a drive motor 6 fixedly mounted on the top of the fan base plate 1. The model and power of the drive motor 6 are selected based on specific needs. A transmission assembly is mounted on the output shaft of the drive motor 6. The transmission assembly specifically includes a first synchronous pulley 7 fixedly mounted on the output shaft of the drive motor 6 and a second synchronous pulley 8 fixedly mounted on the rotating ring 4. The first and second synchronous pulleys 7 and 8 are driven by a common synchronous belt 9. When the drive motor 6 is started and drives the output shaft to rotate, the first synchronous pulley 7 rotates accordingly, and the second synchronous pulley 8 rotates via the synchronous belt 9, thereby driving the rotating ring 4 and the axial flow blades 5 to rotate.

[0040] Specifically, the first synchronous wheel 7 and the second synchronous wheel 8 are both pulleys, and the synchronous belt 9 is a belt.

[0041] In order to reduce the vibration generated by the FRP fan during operation, we installed a buffer mechanism at the bottom of the fan base plate 1. The buffer mechanism specifically includes a plurality of damping spring shock absorbers 13 fixedly installed in a matrix at the bottom of the fan base plate 1. The number and distribution of the damping spring shock absorbers 13 are designed according to specific needs to ensure the elastic support effect of the fan base plate 1. At the same time, two slides 10 are symmetrically fixedly installed on both sides of the fan base plate 1. The slides 10 are slidably fitted with limit frames 12, and the limit frames 12 are installed on the bottom box 11 or other fixed structures by bolts or other fixing methods. By using the limit frame 12 to slide with the slide plate 10, the fan base plate 1 can be longitudinally limited in sliding so that it can only move vertically. In this way, when the power mechanism is moving, the transmission of vibration can be reduced, providing protection for the FRP fan.

[0042] Specifically, a damping spring shock absorber is a device with a significant shock-absorbing effect. It combines the dual advantages of low frequency and high damping of steel springs. Through the elastic deformation of the spring and the damping action of the damper, it effectively reduces or eliminates periodic vibrations or transient shocks caused by the equipment's operation or external influences. It contains spring steel and damping force generation mechanisms such as damping oil and valves. When the equipment is subjected to vibration, the spring first absorbs some of the vibration energy. The damper then converts the remaining vibration energy into heat through the flow of oil and the opening of valve discs, thereby achieving the shock absorption effect.

[0043] The present application can be used in the field of wind turbine technology, and can also be used in other fields applicable to the present application.

[0044] Example 2

[0045] refer to Figure 5-6Based on the first embodiment, an improvement is provided: a mounting base, applied to the field of fan technology, comprising a bottom box 11, the shape and size of which are designed according to specific requirements. Multiple limit brackets 12 are symmetrically fixedly mounted on the top of the bottom box 11, and the bottom ends of multiple damping spring shock absorbers 13 all contact the top of the bottom box 11 to provide support therefor. A mounting hole is provided on one inner wall of the bottom box 11 for mounting a filter mechanism.

[0046] A delivery docking mechanism is installed on one side of the bottom box 11, connecting to the fiberglass reinforced plastic fan's docking pipe 3. This mechanism specifically includes a docking cover 15 fixedly mounted on one side of the bottom box 11. The bottom end of the docking pipe 3 extends into the docking cover 15 and fits tightly against its inner wall. A mounting pipe 14 is fixedly mounted to the bottom of the docking cover 15. The bottom end of the mounting pipe 14 extends into the bottom box 11 and is fixedly mounted with a gas supply pipe 16. This allows gas entering the docking pipe 3 to be transported to the filtration mechanism via the docking cover 15, mounting pipe 14, and gas supply pipe 16.

[0047] The filtration mechanism specifically includes a pretreatment box 17 fixedly mounted within the mounting hole, with one side of the pretreatment box 17 extending into the base box 11. One end of an air supply pipe 16 extends into the pretreatment box 17 and is fixedly connected to one inner wall of the pretreatment box 17. An air outlet pipe 18 is fixedly mounted on the other inner wall of the pretreatment box 17. One end of the air outlet pipe 18 penetrates the other inner wall of the base box 11 and extends to the outside of the base box 11 for connection to an external pipeline.

[0048] A cover plate 19 is sealed and mounted inside the pretreatment box 17. A handle is fixedly mounted on one side of the cover plate 19 for easy disassembly. A dust removal screen plate 20 is fixedly mounted on the other side of the cover plate 19, and the dust removal screen plate 20 fits tightly against the inner wall of the pretreatment box 17. After the gas is transported to the pretreatment box 17 through the gas pipe 16, the dust removal screen plate 20 can be used to pre-filter the gas to remove impurities and particulate matter. The filtered gas can be discharged through the outlet pipe 18, so that the burden on the filter element in the purification equipment can be reduced during subsequent gas processing. At the same time, when the dust removal screen plate 20 needs to be cleaned or replaced, the cover plate 19 can be disassembled by the handle, so that the dust removal screen plate 20 can be taken out of the pretreatment box 17 for maintenance.

Those skilled in the art can make any selection according to their needs or convenience.

[0050] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
