[0027] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0028] like Figures 1 to 4As shown, a dust removal device for calcium carbonate production includes a shell 1, the lower end of the shell 1 is fixedly connected to a base 2, a fan 3 is arranged inside the shell 1, one end of the fan 3 is fixedly connected to an air inlet pipe port 4, and the rear end of the fan 3 is fixedly connected to an air outlet pipe port 5; it also includes a filtering mechanism, the filtering mechanism includes a filter box 6 arranged inside the shell 1, a water filter net 11 is arranged inside the filter box 6, the front and rear ends of the water filter net 11 are fixedly connected to two groups of fixed plates 10, the outward ends of the two groups of fixed plates 10 are fixedly connected to the inner wall of the shell 1, the front and rear upper ends of the water filter net 11 are fixedly connected to two groups of filter nets 12, the upper ends of the two groups of filter nets 12 are fixedly connected, the water filter net 11 and the two groups of filter nets 12 are cooperated to form a "triangle" shape, and the opening of the filter net 12 is smaller than the opening of the water filter net 11.

[0029] Specifically, such as Figure 1 and Figure 4 As shown, the outer side of the fan 3 is sleeved inside one end of the outer shell 1, and one end of the fan 3 is arranged outside the outer shell 1. The upper end of the air outlet pipe 5 passes through the rear end of the filter box 6 and is arranged at the upper end of the inner part of the filter box 6. One side of the upper end of the filter box 6 is fixedly connected with the air outlet 7 and the water inlet pipe 8. The outer side of the air outlet 7 and the outer side of the water inlet pipe 8 are both sleeved at one end of the outer shell 1. The lower side of the rear end of the filter box 6 is fixedly connected with the water outlet pipe 9. The water outlet pipe 9 is arranged below the vibration plate 13, and the outer side of the water outlet pipe 9 is sleeved at the rear end of the outer shell 1.

[0030] During operation, filtered water is first added from the water inlet pipe 8, and then the fan 3 is started. The air inlet pipe 4 draws air inward, and the calcium carbonate particles floating in the air are sucked into the fan 3. The wind and the calcium carbonate particles move along the inner wall of the air outlet pipe 5, and then enter the filtered water inside the filter box 6 from the opening at the upper end of the air outlet pipe 5. The wind enters the filtered water, bubbles emerge and are discharged from the air outlet 7. The calcium carbonate particles entering the water slowly sink under the influence of gravity. After the filtration is completed, the filtered water is discharged from the water outlet pipe 9, and the filtered calcium carbonate particles are taken out, which is convenient for the recovery of calcium carbonate and reduces the loss of resources.

[0031] like Figure 1 and Figure 4 As shown, two groups of vibration plates 13 are fixedly connected to the lower ends of the two groups of fixed plates 10, and the vibration plates 13 transmit force to the fixed plates 10 and the filter screen 12 through vibration. Two groups of connecting plates 14 are symmetrically arranged below the filter screen 12, and the front and rear ends of the connecting plates 14 are fixed to the inside of the filter box 6. One end of the connecting plate 14 is inclined to the bottom and side of the inside of the filter box 6, and the other end of the connecting plate 14 is fixedly connected to the activated carbon plate 15. A motor 16 is arranged inside the lower end of the outer shell 1, and the output end of the motor 16 is fixedly connected to a rotating shaft 17. The upper end of the rotating shaft 17 passes through the outer shell 1 and the bottom end of the filter box 6 and is arranged inside the filter box 6. The outer side of the rotating shaft 17 is fixedly connected to a spiral stirring blade 18.

[0032] During operation, after the calcium carbonate particles sink in the filtered water, they slowly gather on the platform of the fixed plate 10 and the filter screen 12. The openings of the filter screen 12 prevent the entry of calcium carbonate particles, while a small number of too fine calcium carbonate particles and dust enter between the two groups of connecting plates 14 through the openings of the water filter screen 11 and the filter screen 12. When the filter screen 12 filters the calcium carbonate, the vibration plate 13 vibrates regularly to prevent the calcium carbonate particles from blocking the openings of the filter screen 12 and affecting the efficiency of drainage after filtration. When fine calcium carbonate particles and dust enter between the two groups of connecting plates 14, the motor 16 is started, and the output shaft of the motor 16 drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the spiral stirring blade 18 to rotate. The spiral stirring blade 18 rotates to stir the filtered water. After the filtered water is stirred, The activated carbon plate 15 can adsorb dust and fine calcium carbonate particles in the filtered water more quickly, thereby purifying impurities in the filtered water. Finally, after the filtration operation is completed, the outlet pipe 9 is opened and the filtered water flows out from the outlet pipe 9. Because the through holes of the water filter 11 are larger than the through holes of the filter 12, the flow rate of the filtered water is larger when it is discharged. By setting the vibration plate 13 to vibrate the fixed plate 10, the calcium carbonate particles are prevented from clogging the through holes of the filter 12 during filtration, thereby affecting the efficiency of drainage after filtration. By setting the water filter 11, the flow rate of water is increased, thereby improving the working efficiency of drainage. By setting the spiral stirring blades 18 and the activated carbon plate 15, the dust and excessively fine calcium carbonate particles in the water are adsorbed, so that the filtered water is restored to its form before filtration, which facilitates the reuse of the filtered water.
