[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example: Reference Figure 1-6 The dust recovery device for aluminum hydroxide production shown includes a recovery device 1, a connecting pipe 2, and a collection component 3. A partition 4 is installed inside the collection component 3, and a hole is provided in the middle of the partition 4. The inlet of the connecting pipe 2 is connected to the hole, and the outlet of the connecting pipe 2 is connected to the exhaust fan of the recovery device 1. In order to filter impurities, a filter mechanism is provided on the partition 4, and a dust collection mechanism is provided at the bottom of the collection component 3.
[0025] As one embodiment of this example, the filter mechanism: the filter screen 9 is mounted on the partition plate 4 by bolts. In order to ensure the passability of the filter screen 9, a cleaning component that can clean the filter screen is provided in the middle of the filter screen 9.
[0026] As one embodiment of this invention, the cleaning component is as follows: a rotating shaft 11 is rotatably connected to the middle of the filter screen 9, and a set of cleaning brushes 13 are installed on the outer section of the rotating shaft 11. In order to make the cleaning brushes 13 rotate and clean the filter screen 9, a fan blade 12 is installed on the inner section of the rotating shaft 11. The fan blade 12 is powered by the air drawn by the exhaust fan when it is working, so that the fan blade 12 rotates and drives the cleaning brushes 13 to rotate through the rotating shaft 11.
[0027] As one embodiment of this invention, in order to strengthen the structural strength of the filter screen 9, a set of reinforcing members 10 are provided on the inner end face of the filter screen 9. The reinforcing members 10 are three-star shaped and have a hole in the middle of the reinforcing members 10. The rotating shaft 11 is rotatably connected in the hole.
[0028] As one implementation method in this embodiment, the collection mechanism has a perforation 31 on the inner bottom surface of the collection component 3, a through hole connecting to the outside on the inner wall of the perforation 31, and two sets of symmetrical sliding strips 5 below the perforation 31 (bottom surface of the collection component 3). The collection hopper 8 is slidably connected in the sliding strips 5 (and the collection hopper 8 is slidably connected in the perforation 31). When some dust cannot be recovered through the connecting pipe 2 and accumulates on the collection component 3, it is collected by the collection hopper 8.
[0029] As one implementation method in this embodiment, a limiting mechanism is provided on the slide bar 5 in order to fix the collection bucket 8.
[0030] As one implementation method in this embodiment, the limiting mechanism is as follows: a positioning groove is provided on the top surface of the slide bar 5, and a positioning pin 7 is slidably connected in the positioning groove. The bottom surface of the positioning pin 7 is connected to the positioning groove through a spring 6. The top of the positioning pin 7 is hemispherical so that the collection bucket 8 can be picked up and put in.
[0031] The working principle of this utility model is as follows: By starting the exhaust fan in the recycling device 1, the exhaust fan drives the gas flow. The gas flows from the inlet of the collection component 3, passes through the filter screen 9, and when it passes through the fan blade 12, it drives the fan blade 12 to rotate. The rotating fan blade 12 drives the rotating shaft 11 to rotate on the reinforcing component 10 and the filter screen 9, thereby driving the cleaning brush 13 to rotate and clean the filter screen. The dust swept down is carried by the gas and passes through the connecting pipe 2 into the recycling device 1.
[0032] When some dust falls into the angle between the collecting component 3 and the partition 4, the design of the perforation 31 and the collecting hopper 8 allows the dust that would have accumulated in the angle to fall into the collecting hopper 8, completing the collection task and reducing the cleaning difficulty for the staff. Then, when the work stops, the pull ring on the collecting hopper 8 is pulled, causing the collecting hopper 8 to slide on the slide bar 5 and push against the positioning pin 7, causing the positioning pin 7 to press down on the spring 6, releasing the limit of the collecting hopper 8 and completing the cleaning task.
[0033] The electromechanical connections involved in this utility model are common practices used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments; they are common knowledge.
[0034] Components not described in detail in this article are existing technologies.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
