Description

Technical Field

[0001] This utility model relates to the field of mineral processing technology, and in particular to a screening device for lime powder processing. Background Technology

[0002] Lime powder is a white powdery substance with calcium carbonate as its main component, widely used in construction, metallurgy, environmental protection, agriculture, and many other fields. It exhibits good coagulation and cementing properties when mixed with water, making it an important component of traditional building materials and soil conditioners. Screening is a crucial step in the processing of lime powder, used to classify its particle size to meet the requirements of different application scenarios.

[0003] Currently, due to different raw material sources, limestone may contain a certain proportion of soil and other impurities. These impurities not only affect the purity of lime powder but may also cause screen clogging, reducing screening efficiency. If lime powder is screened without being fully dried, the high moisture content will cause the material to adhere to the screen holes or the inner wall of the equipment, severely affecting the screening effect and even causing frequent shutdowns for cleaning, increasing maintenance costs and time consumption. Furthermore, the choice of screen directly affects screening efficiency and product particle size distribution. If the screen mesh is too fine, although it can meet the requirements of fine screening, it will significantly increase screening resistance, leading to a decrease in screening efficiency; conversely, if the screen mesh is too large, it will be unable to effectively separate the required particle size, affecting product quality.

[0004] Therefore, there is an urgent need for a high-efficiency screening device for lime powder processing. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example 1: A screening device for lime powder processing, such as Figure 1 , Figure 2 and Figure 5 As shown, the device includes a frame 1, a housing 2, a feed hopper 3, a guide cylinder 4, a heating cylinder 5, a screening cylinder 6, guide plates 8, and a collection frame 15. The housing 2 is mounted on the frame 1. The guide cylinder 4 is inclinedly arranged inside the housing 2. The feed hopper 3 is connected to the upper right of the guide cylinder 4 to guide the lime powder to be screened into the device. The heating cylinder 5 is installed outside the guide cylinder 4 to heat and dry the lime powder inside, effectively reducing the moisture content of the material and preventing clumping and screen blockage caused by moisture, thereby improving screening efficiency and quality. Six guide plates 8 are evenly spaced and inclined on the frame 1 to ensure that the material can flow smoothly from the housing during the screening process. The screening cylinder 6 slides to different areas. The screening cylinder 6 is rotatably installed on the left side of the machine casing 2. The screening cylinder 6 has gradually increasing perforations from the upper right to the lower left. The upper right of the screening cylinder 6 is connected to the lower left of the guide cylinder 4. The guide plates 8 are all rotatably connected to the screening cylinder 6. The perforations of the screening cylinder 6 between every two guide plates 8 have different apertures, so that lime powder of different particle sizes can pass through the corresponding screen holes, thereby achieving fine grading. The lower part of the frame 1 is equipped with a sliding collection frame 15, and four partitions are set between the collection frames 15 to divide it into five independent placement slots, which can collect lime powder of different particle sizes separately for subsequent classification.

[0022] When lime powder needs to be screened, the operator pours the lime powder to be screened into the inclined guide cylinder 4 through the feed hopper 3. During this process, the lime powder slides down the inside of the guide cylinder 4 under the action of gravity. At the same time, the heating cylinder 5 is activated to heat and dry the lime powder in the guide cylinder 4, effectively removing the moisture, improving the subsequent screening efficiency and preventing agglomeration, thereby improving the screening accuracy and product quality. The dried lime powder then slides down to the screening cylinder 6. The different apertures inside the screening cylinder 6 allow lime powder of different particle sizes to be reasonably classified and collected into the placement groove between the different partitions of the collection frame 15, achieving fine screening.

[0023] Example 2: Based on Example 1, such as Figure 3 and Figure 4 As shown, it also includes a flat motor 7, a mounting frame 9, an electric push rod 10, a scraper 11, a circular plate 12, guide rods 13, and an elastic element 14. A flat motor 7 is located at the lower left of the screening cylinder 6. A mounting frame 9 is connected to the flat motor 7. An electric push rod 10 is mounted on the mounting frame 9. A circular plate 12 is connected to the top of the push rod of the electric push rod 10. Eight guide rods 13 are connected to the push rod of the electric push rod 10. Each pair of guide rods 13 is slidably connected to a scraper 11. The eight guide rods... Each of the four scraper plates 13 is fitted with an elastic element 14. The lower end of the elastic element 14 is connected to the guide rod 13, and the upper end is connected to the scraper plate 11. All four scraper plates 11 are tightly attached to the guide cylinder 4. The scraper plate 11 has a U-shaped structure and slides in contact with the circular plate 12 through the inclined surface. The electric push rod 10 can push the circular plate 12 forward, causing the scraper plate 11 to slide and expand along the inclined surface, so that it fits more tightly against the inner wall of the guide cylinder 4, realizing the extension and retraction adjustment function of the scraper plate 11. The scraping force can be adjusted as needed to improve the cleaning effect.

[0024] like Figure 5 As shown, it also includes a guide plate 16 and a pulley frame 17. The guide plate 16 is provided on the frame 1, and two pulley frames 17 are provided on the guide plate 16. Both pulley frames 17 are in sliding contact with the collection frame 15, which reduces sliding friction, improves operating efficiency, and facilitates quick replacement and cleaning.

[0025] When it is necessary to clean the lime powder adhering to the inner wall of the guide cylinder 4, the flat motor 7 is started, driving the mounting frame 9 to rotate. Simultaneously, the electric push rod 10, the guide rod 13 connected to it, and the scraper 11 rotate synchronously, so that the scraper 11 is in close contact with the inner wall of the guide cylinder 4. The rotational motion efficiently scrapes and cleans the lime powder adhering to the inner wall, effectively preventing material blockage and agglomeration, and ensuring the smooth operation of the guide cylinder 4. During the cleaning process, the electric push rod 10 can push the circular plate 12 to move along the push rod axis, so that the circular plate 12 and the inclined surface of the scraper 11 make relative sliding, thereby pressurizing the scraper 11 to expand it outward, enhancing its contact pressure with the inner wall of the guide cylinder 4, and improving the scraping efficiency. After the cleaning is completed, the electric push rod 10 moves in the opposite direction, driving the circular plate 12 to retract. The scraper 11 automatically resets under the restoring force of the elastic element 14, returning to the initial state, which is convenient for the next cleaning operation.

It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
