Description

Technical Field

[0001] The utility model relates to the technical field of environmentally friendly pulverizers, in particular to an environmentally friendly fan for pulverizing dust. Background Art

[0002] With the improvement of industrial automation level, people are paying more and more attention to environmental pollution and occupational health and safety. The traditional dust crushing process is usually accompanied by a large amount of dust emission, which not only pollutes the surrounding environment, but also may have adverse effects on the health of operators. The requirements of various countries for air quality management are becoming more and more stringent. Therefore, people began to seek a technology that can effectively control dust emissions to reduce the harm to the environment and human health.

[0003] Environmentally friendly dust crushing fans are mainly used to reduce dust pollution generated during the crushing process and improve the air quality of the working environment. Environmentally friendly dust crushing fans should be equipped with efficient filtration systems, such as HEPA filters, to capture fine dust particles generated during the crushing process. These filters can effectively filter out dust as small as microns to ensure that the exhausted air is clean. The fan should maintain a low noise level when working to avoid disturbing the working environment. The use of advanced noise reduction technology and structural design can effectively reduce the noise generated by the fan when it is running. Utility Model Content

After the fan is used for a long time, the fan blade 4 will be damaged. A blade mounting component 300 is installed on each fan blade 4 and the blade base 5. The fixing cover 301 is rotated to detach the fixing cover 301 from the blade base 5, and then the fan blade 4 can be replaced separately. The other end of the spring 204 is fixedly connected to a support plate 7. The right side of the support plate 7 is fixedly connected to the right side of the inner groove of the fixing member 2. A plurality of sliding grooves are provided on the outer wall of the blade base 5. The inside of the sliding groove is slidably connected to the sliding member 303. A fixing hole is provided on the bottom right side of the sliding member 303. The inner wall of the fixing hole is slidably connected to the fixing rod 302 to prevent the fan blade 4 from falling due to gravity. A threaded groove is provided on the left side of the inner wall of the arc groove of the blade base 5 to facilitate the installation of the fixing cover 301.

[0033] The fan installation assembly 200 includes a support rod 203 fixedly connected to the inner wall of the groove opened by the fixing member 1 2, the outer axis of the support rod 203 is rotatably connected to a pressing plate 201, a notch is opened at the bottom of the pressing plate 201, a spring 204 is fixedly connected to the right side of the top of the notch, a clamping piece 202 is clamped on the left side of the spring 204, and the bottom of the clamping piece 202 is fixedly connected to the fixing member 2 6. When installing the fan, the fixing member 2 6 on the fixing frame 3 is pressed so that the clamping piece 202 on it is driven, and the top of the clamping piece 202 has a certain slope. The pressing plate 201 is lifted up and the right spring 204 is squeezed at the same time. After the pressing plate 201 passes over the highest point of the engaging member 202, the spring 204 on the right side of the pressing plate 201 will engage the left side of the pressing plate 201 into the gap behind the engaging member 202 due to the rebound force. At the same time, the engaging member 202 will enter the groove on the right side of the pressing plate 201 to engage with the fan, thereby fixing the fan on the dust collection duct 1. When replacing the fan, the right side of the pressing plate 201 is pressed to lift the left side thereof to break the engagement state with the engaging member 202, and the fan can be disassembled.

[0034] The blade mounting assembly 300 includes a fixing rod 302 fixedly connected to the right side of the arc groove opened on the blade base 5, a sliding member 303 is slidably connected to the outer axis of the fixing rod 302, the top of the upper sliding member 303 is fixedly connected to the fan blade 4, and a fixing cover 301 is threadedly connected to the left side of the inner wall of the arc groove. When assembling the fan blade 4, the sliding member 303 at the bottom of the fan blade 4 is inserted into the sliding groove of the outer wall of the blade base 5, and the fixing hole on the sliding member 303 is inserted into the fixing rod 302, so that the fan blade 4 is fixed on the blade base 5. After the fan blade 4 is installed, the fixing cover 301 is rotated into the blade base 5 to further fix the fan blade 4 to prevent the fan blade 4 from being thrown off when the fan rotates.

[0035] Working principle: When assembling the fan blade 4, the sliding piece 303 at the bottom of the fan blade 4 is inserted into the sliding groove of the outer wall of the blade base 5, and the fixing hole on the sliding piece 303 is inserted into the fixing rod 302, so that the fan blade 4 is fixed on the blade base 5 to prevent the fan blade 4 from falling due to gravity. After the fan blade 4 is installed, the fixing cover 301 is rotated into the blade base 5 to further fix the fan blade 4 to prevent the fan blade 4 from being thrown off when the fan rotates. When the fan blade 4 needs to be replaced, the fixing cover 301 is rotated in the opposite direction to separate it from the blade base 5, the fan blade 4 that needs to be replaced is taken out, and the undamaged fan blade 4 is installed, and the fixing cover 301 is screwed on. When installing the fan, press The fixing frame 3 is pressed so that the fixing part 26 on the fixing frame 3 drives the engaging part 202 thereon. The top of the engaging part 202 has a certain slope to lift the pressing plate 201 and squeeze the right spring 204 at the same time. After the pressing plate 201 passes the highest point of the engaging part 202, the spring 204 on the right side of the pressing plate 201 will engage the left side of the pressing plate 201 into the gap behind the engaging part 202 due to the rebound force. At the same time, the engaging part 202 will enter the groove on the right side of the pressing plate 201 to achieve engagement, thereby fixing the fan on the dust collection duct 1. When replacing the fan, the right side of the pressing plate 201 is pressed to lift its left side to destroy the engagement with the engaging part 202, and the fan is disassembled.
