Description

Technical Field

[0001] This utility model belongs to the field of calcium carbonate processing technology, specifically relating to a multi-stage vibrating screen for removing impurities from calcium carbonate powder. Background Technology

[0002] Calcium carbonate is an inorganic compound and a major component of limestone, marble, and other minerals. It is typically a white, odorless crystal and is practically insoluble in water. During processing, calcium carbonate requires sorting equipment to classify it, that is, to sieve and separate calcium carbonate particles of different sizes.

[0003] Patent announcement number CN219560399U, entitled "A Multi-Stage High-Efficiency Vibrating Screen for Removing Impurities from Calcium Carbonate Powder," discloses a vibrating screen body. The vibrating screen body has a sealed door on its front surface, an observation window on the inner wall of the sealed door, a feed inlet at the top of the vibrating screen body containing calcium carbonate powder, a vibrator on one side of the vibrating screen body, a drive motor at one end of the vibrator, a support frame at the bottom of the drive motor, a sliding groove inside the vibrating screen body, a fixing bolt above the sliding groove, a first filter screen on one side of the sliding groove, a second filter screen below the first filter screen, and a third filter screen below the second filter screen. Its technical features include the ability to remove the second filter screen from the vibrating screen body by utilizing the sliding groove, fixing bolt, support block, and screw holes, thereby cleaning residual impurities on the second filter screen.

[0004] However, the existing technical problems or defects are that in the process of screening and classifying calcium carbonate, it is necessary to manually pull out each filter screen before screening and cleaning. Furthermore, the third filter screen at the bottom cannot completely catch the calcium carbonate impurities, causing them to fall to the bottom of the vibrating screen body, resulting in tedious cleaning. Therefore, based on the above defects, the applicant has proposed a better technical solution to solve the above technical problems.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0030] 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.

[0031] Example

[0032] like Figures 1 to 6 As shown, a multi-stage vibrating screen for removing impurities from calcium carbonate powder includes a tank 1, with an inlet 11 and an outlet 12 at the top and bottom ends of the tank 1, respectively. It also includes a vibrating mechanism 2, connecting columns 3, a driving mechanism 4, and multiple screening mechanisms 5. Vibrating mechanisms 2 are provided at the four corners of the bottom of the tank 1. Each vibrating mechanism 2 has a vertically inserted connecting column 3, and the upper end of the connecting column 3 is slidably connected to the upper end of the tank 1. The lower ends of two connecting columns 3 located on the same side are connected to the driving mechanism 4. Multiple screening mechanisms 5 are vertically slidably connected to the connecting columns 3 and are inclined in a Z-shape. The lower end of each screening mechanism 5 has a recovery port 13 on the side wall of the tank 1.

[0033] This utility model employs multiple screening mechanisms 5 arranged in a Z-shape at an inclination inside the tank body 1, which facilitates the screening and classification of calcium carbonate of different particle sizes. The tank body 1 is provided with a corresponding recovery port 13 for the screening mechanism 5 to facilitate the classified collection of calcium carbonate. The discharge port 12 at the bottom of the tank body 1 discharges calcium carbonate impurities for easy cleaning, thereby improving work efficiency.

[0034] In this embodiment, please refer to Figure 3 The vibration mechanism 2 includes a base 21 and a vibration component 22. A cavity 211 is formed inside the base 21. A connecting column 3 is inserted into the cavity 211, and an annular connecting block 6 is fixedly mounted on it. Vibration components 22 are located at both the upper and lower ends of the annular connecting block 6. Specifically, the vibration component 22 includes a guide rod 221 and a pressure spring 222. One end of the guide rod 221 is fixedly mounted on the annular connecting block 6, and the other end is slidably connected to the base 21. The pressure spring 222 is sleeved on the guide rod 221.

[0035] The vibration component 22 in the vibration mechanism 2 of this utility model can realize the first-stage vibration screening of the screening mechanism 5 on the connecting column 3 under the drive of the drive mechanism 4. In specific operation, the connecting column 3 moves up and down under the action of the drive mechanism 4, and the vibration component 22 on it can drive the connecting column 3 to vibrate up and down by utilizing the elastic action of the pressure spring 222. The vibration generated by the connecting column 3 is used to perform vibration screening on the screening mechanism 5 on it.

[0036] In this embodiment, please refer to Figures 1-4 The drive mechanism 4 includes a connecting plate 41, a drive motor 42, and a cam 43 in the shape of a plum blossom. The connecting plate 41 is connected between the lower ends of the two connecting columns 3, and the cam 43 is abutted at the middle of its lower end. The drive motor 42 is located on the outer wall of the tank 1, and its output end is connected to the cam 43. In specific operation, the drive mechanism 4 uses the plum blossom-shaped cam 43 to intermittently lift the connecting plate 41, and uses the pressure spring 222 to drive the connecting column 3 to move up and down. Finally, under the action of the vibration component 22, the connecting column 3 is driven to vibrate up and down. The vibration generated by the connecting column 3 is used to perform vibration screening on the screening mechanism 5 installed on it, effectively improving its vibration screening efficiency.

[0037] In this embodiment, please refer to Figure 5 and Figure 6 The screening mechanism 5 includes a sliding cylinder 51, a support frame 52, a screen 53, a pressure spring 54, and a pad 55. A connecting column 3 has a recessed annular groove 31, in which the sliding cylinder 51 slides. The pad 55 is located at the lower end of the annular groove 31, between the sliding cylinder 51 and the pad 55. A pressure spring 54 is sleeved on the connecting column 3. The support frame 52 is fixedly mounted on the sliding cylinder 51, and the screen 53 is located within the support frame 52.

[0038] In this invention, the pressure spring 54 and pad 55 in the screening mechanism 5 enable two-stage vibration screening of the screen 53. Specifically, when the drive mechanism 4 drives the connecting column 3 to vibrate up and down, the pressure spring 54 and pad 55 on the connecting column 3 interact to vibrate and screen the screen 53 again. Through the combined action of primary and secondary vibration screening, the screening and classification of calcium carbonate is efficiently achieved, effectively improving work efficiency.

[0039] Specifically, in this example, there are three screening mechanisms 5, and the mesh size of the screens 53 on the three screening mechanisms 5 decreases from top to bottom, which facilitates the screening and classification of calcium carbonate materials of different specifications.

[0040] The working principle of this utility model:

[0041] This utility model provides a multi-stage vibrating screen for removing impurities from calcium carbonate powder. In specific use, calcium carbonate material is introduced into the tank 1 through the feed inlet 11 and first falls on the screening mechanism 5 at the uppermost displacement layer. The connecting column 3 moves up and down under the action of the drive mechanism 4, and the vibration component 22 set on it can drive the connecting column 3 to vibrate up and down by utilizing the elastic action of the pressure spring 222. The vibration generated by the connecting column 3 is used to vibrate the screening mechanism 5 set on it.

[0042] Simultaneously, when the drive mechanism 4 drives the connecting column 3 to vibrate up and down, the pressure spring 54 and the pad 55 set on the connecting column 3 interact to vibrate and screen the screen 53 again. Calcium carbonate materials of different sizes are screened from top to bottom through the mesh size of the screen 53, and finally collected and processed through the recycling port 13. This utility model uses multiple screening mechanisms 5 arranged in a Z-shape in the tank 1 to facilitate the screening and classification of calcium carbonate of different particle sizes. The tank 1 is provided with a corresponding recycling port for the screening mechanism 5 to facilitate the classified collection of calcium carbonate. The discharge port 12 at the bottom of the tank 1 discharges calcium carbonate impurities for easy cleaning, improving work efficiency.
