Description

Technical Field

[0001] This utility model relates to the field of dust control technology, specifically to an air purification device for lime powder processing. Background Technology

[0002] Lime powder is a white powdery substance with calcium carbonate as its main component. It has a wide range of applications. Its dust or suspended droplets can irritate mucous membranes, although not as severely as sodium hydroxide, but it can still cause sneezing and coughing. Like alkalis, it can emulsify fats, absorb moisture from the skin, dissolve proteins, and irritate and corrode tissues.

[0003] In the prior art, Chinese utility model publication number CN219050802U discloses an air purification device for lime powder processing, including a purification box. An air inlet is located on one side of the purification box, and a blowing plate is located on the same side of the air inlet. The blowing plate is fixedly mounted on one side of a water pipe, and multiple first nozzles are fixedly connected to the bottom end of the water pipe. Connecting rods are fixedly mounted on both sides of the bottom end of the water pipe. By configuring the blowing plate, water pipe, first nozzles, connecting rods, moving plate, and scraper, air is delivered into the purification box through the air inlet. The airflow drives the blowing plate, which in turn drives the water pipe and first nozzles to move, spraying lime powder in the air to reduce dust. The lime powder falls onto the filter screen. Simultaneously, as the water pipe drives the moving plate, it also drives the scraper to scrape and clean the lime powder, reducing the residue of lime powder in the air, facilitating thorough air purification, and improving the air purification effect.

[0004] The above technical solution uses liquid spraying to suppress dust from lime powder in the air. However, lime powder processing sites usually need to maintain a certain level of dryness to prevent lime powder from absorbing water and emulsifying. Using liquid spraying for dust suppression can easily cause the liquid to evaporate and diffuse into the outside air, directly combining with the lime powder in the air. This causes the lime powder to absorb water and become more sticky. At the same time, after absorbing water, the lime powder changes its properties, resulting in waste of lime powder that cannot be directly recycled. Utility Model Content

[0005] The purpose of this invention is to provide an air purification device for lime powder processing. A fan discharges air from the outer shell and base box to the outside.

[0021] 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.

[0022] This utility model provides, for example Figures 1-4The illustrated air purification device for lime powder processing includes a base box 1 and a housing 2. A connecting pipe 3 connects the base box 1 and the housing 2. Collection frames 4 are fixed around the perimeter of the housing 2. One side of the collection frames 4 extends into the interior of the housing 2 and connects to a fixed box 5. The top end of the connecting pipe 3 penetrates into the interior of the housing 2 and connects to the bottom of the fixed box 5. A rotating shaft 6 is rotatably connected to the opposite side of the collection frames 4 via bearings. One end of the rotating shaft 6 penetrates into the inner cavity of the collection frames 4 and is fixed to a bearing. The scraper 7 gently scrapes the inner wall of the collection box 4. The top of the inner cavity of the fixed box 5 is fixed with an equipment box 8. The inner cavity of the equipment box 8 is provided with a drive assembly 9 that drives the rotating shaft 6. The inner cavity of the base box 1 is horizontally fixed with a support plate 10. The top of the support plate 10 is rotatably connected to a movable shaft 11 through a bearing. The outer side of the movable shaft 11 is fixed with a support frame 12. The inner cavity of the support frame 12 is provided with multiple sets of filter bags 13. The filter bags 13 are connected to the connecting pipe 3. The bottom of the base box 1 is equipped with a fan 14 that is connected to the base box 1.

[0023] The fan 14 drives airflow, drawing in air containing lime powder from the outside into the base box 1. The air is then filtered by the filter bag 13 inside the base box 1, reducing the dust content. Simultaneously, the drive assembly 9 rotates the shaft 6, causing the hanging rod to rotate within the collection frame 4, cleaning the lime powder adhering to the inner wall of the collection frame 4. The lime powder then falls into the dust collection box 18, facilitating the recovery of the lime powder adhering to the device and improving the recycling rate of the air purification device.

[0024] The drive assembly 9 includes a drive motor 91 fixed to the top of the fixed box 5. The output shaft of the drive motor 91 passes through the inner cavity of the equipment box 8 and is fixed with a rotating shaft 92. One end of the rotating shaft 92 is fixed with a drive helical gear 93. The end of the rotating shaft 6 away from the scraper 7 extends into the inner cavity of the equipment box 8 and is fixed with a driven helical gear 94. The drive helical gear 93 is located above the driven helical gear 94 and meshes with each other. The drive motor 91 drives the rotating shaft 92 to rotate, which in turn drives the drive helical gear 93 to rotate. The driven helical gear 94 then drives the four sets of rotating shafts 6 to rotate synchronously. The rotating shafts 6 drive the scraper 7 to lightly scrape the inner wall of the collection frame 4, sweeping off the attached lime powder for easy collection and recycling.

[0025] The support frame 12 has a discharge port 15 on all four sides of its top. The inner cavity of the discharge port 15 is threaded with a connector 16, which is connected to the filter bag 13. The top of the support frame 12 fits against the top of the inner cavity of the base box 1. The connector 16 makes it easy to detach and install the filter bag 13 from the discharge port 15 to collect the lime powder inside the filter bag 13.

[0026] The support plate 10 has through holes 17, which are located around the support frame 12. The through holes 17 facilitate the connection between the upper and lower spaces of the support plate 10. Driven by the fan 14, the air above the support plate 10 flows downward through the through holes 17, promoting the circulation of air inside the device and facilitating the filtration of lime powder.

[0027] A dust collection box 18 is fixed at the bottom of the collection frame 4. The dust collection box 18 is located on the outside of the outer shell 2 and is connected to the collection frame 4. The dust collection box 18 facilitates the collection of lime powder swept off by the scraper 7, so as to prevent the lime powder from flowing directly onto the ground through the collection frame 4.

[0028] The outer side of the base box 1 has a door opening, and the inside of the door opening is hinged to a door 19. A sealing strip 20 is embedded on the outer side of the door 19. The door 19 and the sealing strip 20 facilitate the sealing of the door opening, ensuring the airtightness of the base box 1, and allowing air to flow downward through the connecting pipe 3 and be filtered by the filter bag 13.

[0029] It also includes casters 21 fixed around the bottom of the base box 1. The collection frame 4 is flared. The casters 21 facilitate the movement of the device and improve its flexibility. The shape of the collection frame 4 also facilitates the flow of air in different directions, and the swept lime powder can easily fall into the dust collection box 18.

[0030] In practical use, the device is moved to a location requiring air purification. Then, the fan 14 is turned on, and the fan 14 exhausts the air inside the base box 1 and the outer shell 2, causing the inside of the device to be in a negative pressure state. Then, air needs to be replenished from the outside through the collection frame 4, which brings the air containing lime powder into the fixed box 5. When passing through the collection frame 4, some lime powder will adhere to the inner wall of the collection frame 4, and some will flow through the airflow through the connecting pipe 3 into the base box 1. Then, it is poured into the filter bag 13 through the discharge port 15. The filter bag 13 can filter the fine lime powder in the air. Then, the air enters below the support plate 10 through the through hole 17 and is blown out of the base box 1 again by the fan 14, forming an air circulation. Then, the drive motor 91 drives the rotating shaft 92 to rotate. The rotating shaft 92 drives the scraper 7 to rotate and sweep the lime powder on the inner wall of the collection frame 4, which then slides into the dust collection box 18 for collection.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
