[0002] In modern agricultural production, biofertilizer, as a new type of environmentally friendly fertilizer, is receiving more and more attention for its production and use. The production of biofertilizer involves the mixing process of multiple raw materials, which inevitably produces a lot of dust. This dust not only pollutes the environment and affects the health of workers, but also causes waste of raw materials. Therefore, effectively controlling and treating the dust generated during the mixing process is the key to improving the production efficiency and quality of biofertilizer.

[0003] In the prior art, in order to reduce the spread of dust, a hood is usually installed on the top of the mixing equipment to absorb dust using the negative pressure principle.

[0020] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0021] The present application provides a dust treatment device for the mixing process of raw materials of biological fertilizer, which is mainly used to solve the problem that although the existing technology can capture some flying dust to a certain extent, since the action range of the wind hood is mainly concentrated in the central area of ​​the top of the equipment, it is difficult to effectively adsorb the dust around the equipment and in the corners, resulting in unsatisfactory treatment effect, and provides the following technical solutions, which will be combined with Figure 1-Figure 3 Make a detailed description:

[0022] A dust treatment device for a biological fertilizer raw material mixing process, comprising:

[0023] A U-shaped bin 1 is provided with a hood 2 fixedly disposed in the middle of the top of the U-shaped bin 1, a fan 3 is mounted on the top of the fan 2, and a guide pipe 4 is connected between the air inlet end of the fan 3 and the top of the U-shaped bin 1;

[0024] The hollow column 5 is evenly spaced and surrounds the outside of the U-shaped bin 1. The upper side of the hollow column 5 is connected to the U-shaped bin 1 through a connecting pipe 6. The middle of the outer wall of the hollow column 5 is evenly distributed with air inlet holes 501. The inside of the hollow column 5 is movably provided with an activated carbon rod 7. The bottom end of the hollow column 5 is fixed with a round table seat 8.

[0025] The dust blocking assembly 9 is used to prevent dust from escaping. The dust blocking assembly 9 includes extension plates 901 fixedly mounted at both ends of the U-shaped bin 1. A winding wheel 902 is rotatably connected between the extension plates 901. A dustproof curtain 903 is wound in the wheel groove of the winding wheel 902. A counterweight rod 904 is provided on the side of the dustproof curtain 903 away from the winding wheel 902.

[0026] The specific implementation process of the dust treatment device in the biological fertilizer raw material mixing process:

[0027] Move the U-shaped bin 1 to the top of the equipment, making sure that the wind hood 2 corresponds to the middle position of the top of the equipment. Then, rotate the reel 902 to unfold the dust curtain 903 to prevent dust from escaping from the opening of the U-shaped bin 1. Turn on the exhaust fan 3 to create negative pressure in the hollow column 5, attracting the air around the equipment to flow into the hollow column 5. The flying dust flows into the hollow column 5 with the air and is adsorbed by the activated carbon rod 7. When the equipment needs to be operated, the dust curtain 903 can be rolled up and fixed in place by the hook 905 and the ring 906.

[0028] The dust treatment device for the biological fertilizer raw material mixing process can effectively cover the surroundings and corners of the equipment and comprehensively treat the dust through the design of the hollow column 5 and the dust shielding component 9. The negative pressure is generated in the hollow column 5 by the exhaust fan 3, so that the air around the equipment flows into the hollow column 5, thereby sucking the flying dust into the hollow column 5. The activated carbon rod 7 movably arranged inside the hollow column 5 can absorb the incoming dust and effectively prevent the secondary diffusion of the dust. Through this dust treatment device for the biological fertilizer raw material mixing process, the diffusion of dust can be more comprehensively controlled and the cleanliness of the production environment can be improved.

[0029] like Figure 1 As shown, in some embodiments, the upper end of the hollow column 5 is open and is threadedly connected with a top cover 502. More specifically, the activated carbon rod 7, which serves as the main medium for dust adsorption, will gradually become saturated or fail with the increase of usage time. The threaded top cover 502 makes it simple and quick to replace the activated carbon rod 7. Only the top cover 502 needs to be opened to take out the old activated carbon rod 7 and insert a new activated carbon rod 7.

[0030] like Figure 3 As shown, in some embodiments, the inner bottom wall of the hollow column 5 is connected to a spring 10, and the upper end of the spring 10 is connected to a movable disk 11. The movable disk 11 is slidably connected to the inner wall of the hollow column 5. More specifically, the spring 10 can play a buffering role. When the activated carbon rod 7 is put in or taken out, the impact on the activated carbon rod 7 can be reduced, thereby protecting the activated carbon rod 7 from damage. Since the spring 10 has elastic force, when the staff takes out the activated carbon rod 7, they can press the activated carbon rod 7 downward and use the elastic force of the spring 10 to pop out the activated carbon rod 7, which makes the process of replacing the activated carbon rod 7 easier and faster.

[0031] like Figure 1 As shown, in some embodiments, the upper end of the truncated pedestal seat 8 is tapered, and a rectangular notch 503 is constructed at the bottom of the hollow column 5. More specifically, the rectangular notch 503 at the bottom of the hollow column 5 can be used as a cleaning channel. When it is necessary to clean the dust in the hollow column 5, the interior can be entered through the notch for cleaning or tools can be used for auxiliary cleaning. This design makes the cleaning work more convenient, and there is no need to completely disassemble the hollow column 5 or move the entire device. The upper end of the truncated pedestal seat 8 adopts a tapered design, which helps to guide the fall, thereby reducing dead angles and improving cleaning efficiency.

[0032] like Figure 2As shown, in some embodiments, a roller 12 is installed at the bottom of the truncated table seat 8, and the roller 12 is a self-locking universal wheel. More specifically, the universal wheel allows the entire bio-fertilizer raw material mixing process dust treatment device to be easily moved within the working area, thereby improving the flexibility and work efficiency of the equipment. Through the universal wheel, the operator can adjust the position of the equipment at will to accurately align it with the area where dust removal is required, thereby ensuring the dust removal effect. The self-locking universal wheel ensures that after the equipment stops, the position will not be offset due to accidental pushing, thereby increasing the stability of the equipment during use.

[0033] like Figure 2 As shown, in some embodiments, hooks 905 are hinged on both sides of the counterweight rod 904, and rings 906 compatible with the hooks 905 are fixed on both sides of the front of the wind hood 2. More specifically, when the dust curtain 903 is not in use, it is rolled up and hung on the rings 906 through the hooks 905 to prevent the dust curtain 903 from swinging at will.

[0034] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
