[0029] The utility model provides an automatic dust recovery device, in which a dust filter is provided in the dust collector. After the dust collector absorbs the dust in the environment into the dust collector, the dust is adsorbed on the dust filter and discharged as clean air. The blower blows the dust in the dust collector and attached to the dust filter toward the discharge port of the dust collector through high-pressure air. The dust discharged from the discharge port is transported to the dust collection box through a pipe. A vibrator is provided on the pipe to accelerate the flow speed of the dust in the pipe and prevent the pipe from being blocked. When a certain amount of dust is collected in the dust collection box, the valve of the dust collection box discharge port is opened, and the dust falls into the dust collection box under the action of gravity. When the dust collection box is full of dust, the valve is closed and the dust collection box is transported to a designated location. During the transportation of the dust collection box, the automatic dust recovery device can continuously collect dust and temporarily store it in the dust collection box to achieve uninterrupted operation, thereby improving the dust collection efficiency. In addition, the blower uses high-pressure air to blow the inside of the dust collector, making it difficult for dust to accumulate inside the dust collector, realizing the dust collector without cleaning, and also improving the overall work efficiency.

[0037] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0038] It should be noted that like reference numerals and letters refer to like items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0039] See also Figure 1 The utility model discloses an automatic dust recovery device, comprising: a dust collector 6, a blower, a dust collection box 5, a dust collection box 4 and a vibrator.

[0040] The feed port of the dust collection box 5 is connected to the discharge port of the dust collector 6 via a pipe 1. The direction of the arrow in the pipe 1 in the accompanying figure represents the direction of movement of the lithium-containing dust. A blower is connected to the dust collector 6 to blow the dust inside the dust collector and attached to the dust filter toward the discharge port of the dust collector 6. A vibrator is provided on the pipe 1. A valve is provided at the discharge port of the dust collection box 5, which is a pneumatic butterfly valve 3. The dust collection box 4 is provided below the discharge port of the dust collection box 5, and a snap-fit ​​portion is provided at the bottom of the dust collection box 5. The dust collection box 4 is provided with a snap, and the snap and snap-fit ​​portions can be interlocked. The feed port of the dust collection box 4 is opposite to the discharge port of the dust collection box 5. After the valve is opened, the material in the dust collection box 5 can automatically fall into the dust collection box 4.

[0041] The dust collector 6 is used to collect lithium-containing powder emitted during the factory production process. A dust filter is provided in the dust collector 6 for filtering and collecting dust (lithium-containing powder). The dust filter is a sintered plate. After the powder is filtered through the sintered plate, clean gas is discharged, and the lithium-containing dust is blown off the sintered plate by compressed air and discharged from the dust collector.

[0042] Furthermore, in this embodiment, the pipeline 1 as a whole adopts a steel wire transparent hose, specifically a steel wire transparent high-strength hose. During the discharge process of the dust collector 6, the lithium-containing dust is discharged through the steel wire transparent high-strength hose. The transparent hose can clearly see the flow speed of the lithium-containing dust and the situation of sticking to the wall, and can fully confirm the falling situation of the lithium-containing dust. By adding a pipeline vibrator outside the pipe, it can vibrate in the case of sticking to the wall or falling slowly to ensure the normal flow of the lithium-containing dust, and prevent the lithium-containing dust from depositing and clogging inside the pipe 1, resulting in poor discharge. Of course, in some embodiments, the pipe 1 can also be made of metal, and only a transparent observation part (observation window) made of acrylic, tempered glass, etc. is provided on the outer wall of the pipe, and observation of the inside of the pipe can also be achieved. In other embodiments, one end of the non-transparent pipe can be replaced with a steel wire transparent hose to achieve observation of the inside of the pipe.

[0043] Furthermore, a dust scraper and a driving mechanism are provided inside the dust collecting box 5. The driving mechanism drives the dust scraper to move relative to the inner wall of the dust collecting box 5 to scrape off the dust attached to the inner wall. Specifically, the driving mechanism is a pneumatic push plate valve 2. The dust scraper is horizontally arranged inside the dust collecting box 5. The outer periphery of the dust scraper is in clearance with the inner wall. The pneumatic push plate valve 2 can drive the dust scraper to move up and down. The dust scraper is mainly used to clean the dust on the inner wall of the dust collecting box 5. After the pulse spray of the blower, the pneumatic push plate valve 2 begins to press downward, pushing all the dust into the dust collecting box 4. The dust collecting box 4 is provided with a level meter. When the dust in the dust collecting box 4 is full and reaches the upper limit level, an alarm is sounded and the pneumatic butterfly valve 3 is closed, and the pneumatic push plate valve 2 stops working. The dust collecting box 5 is mainly used for the initial collection of dust, centrally storing the dust and performing complete material processing therein. The pneumatic butterfly valve 3 is mainly used to open in conjunction with the pneumatic push plate valve 2 when cleaning dust, ensuring that the dust can fall into the dust collecting box 4 in time.

[0044] Workflow:

[0045] The dust collector 6 in this device first collects the lithium-containing dust emitted during the production process, and filters the lithium-containing dust with a diameter of about 0.5 microns through the internal sintered plate. The lithium-containing dust is adsorbed on the surface of the dust collector sintered plate. After being sprayed with pulsed compressed air, the lithium-containing dust falls into the transparent high-strength steel wire hose.

[0046] The material can be discharged stably and visually through the transparent high-strength steel wire hose. When blockage or sticking to the wall is observed, the vibrator is started to vibrate the lithium-containing dust to ensure the smoothness and completeness of the lithium-containing dust discharge.

[0047] The feed port of dust collection box 5 is located on its side wall; initially, the scraper is positioned above the feed port. When lithium-containing dust enters dust collection box 5, pneumatic push-plate valve 2 and pulse control are activated, interlocking with each other. During pulse injection, pneumatic push-plate valve 2 is deactivated. During the pulse-off phase, pneumatic push-plate valve 2 is activated to scrape all lithium-containing dust from dust collection box 5 downward, achieving 100% collection efficiency. Pneumatic butterfly valve 3 is then opened, allowing the lithium-containing dust to fall into dust collection box 4. Both pneumatic butterfly valve 3 and pneumatic push-plate valve 2 are closed before the next pulse injection.

[0048] After the dust box 4 completes the collection of the lithium-containing dust, it determines whether the upper limit of the storage is reached through the dust level meter. When the maximum storage amount is reached, the pneumatic butterfly valve 3 and the pneumatic push plate valve 2 are closed, and the dust collection box 5 collects the dust normally. The dust box 4 unfastens the buckle, covers the lid and directly puts it into the warehouse for archiving. The lithium-containing dust can be sold later, and the lithium-containing resources that are not fully recovered can also be sold to obtain profits.

[0049] In summary, the automatic dust recovery device provided by this utility model is extremely efficient in recovering lithium-containing dust, achieving a 100% recovery rate after capturing the dust that escapes during the production process. This device is fully automatic, saving manual labor and implementing intelligent operation. This device significantly improves indoor air quality, avoids occupational health hazards for workers, and far exceeds the required indoor dust control limits. This device significantly improves the efficiency of lithium resource reuse, creating significant profits for enterprises.
