Description

Technical Field

[0001] This utility model relates to the field of calcium hydroxide filtration and purification equipment, specifically a high-efficiency filtration and purification device for calcium hydroxide production. Background Technology

[0002] The production of calcium hydroxide mainly includes raw material preparation, calcination, digestion, precipitation and filtration. Filtration and purification play a crucial role in the production of calcium hydroxide. This process not only improves the purity and quality of the product, but also helps to increase production efficiency and reduce production costs.

[0003] Patent CN218130361U discloses a filtration and purification device for calcium hydroxide production. This device includes a motor that drives a first threaded rod to rotate, causing a moving block with a brush head to clean the surface of a filter screen. Sediment is swept to the edge of the filter screen, allowing most of the screen's center to remain usable. When not in use, the moving block and brush are placed in a concealed box to prevent the solution from falling directly onto the moving block, thus avoiding prolonged contact and corrosion. When the filter screen becomes clogged, it needs to be removed from the equipment, cleaned, and reinstalled before resuming operation. This eliminates the time-consuming and labor-intensive problem of frequent filter cleaning.

[0004] As can be seen from the above application, the existing filtration and purification devices in calcium hydroxide production are not very efficient at cleaning clogged filters during the precipitation and filtration steps, which reduces the filtration and purification efficiency of calcium hydroxide. Therefore, a high-efficiency filtration and purification device for calcium hydroxide production is proposed. Utility Model Content

[0025] See Figures 1-4As shown in the figure, an embodiment of the present invention discloses a high-efficiency filtration and purification device for calcium hydroxide production, comprising a tube body 10, a calcium hydroxide raw material inlet 101 at the top of the tube body 10, and an outlet 102 at the bottom of the tube body 10. Both the calcium hydroxide raw material inlet 101 and the outlet 102 are provided with connection ports 103, and the connection ports 103 are provided with several threaded holes. An electric slide table 12 is installed on the side wall of the tube body 10, and a roller 20 is installed on the moving block of the electric slide table 12. A cleaning brush 21 is installed on the roller 20. A support frame 30 is provided inside the tube body 10, and a screen 31 is installed inside the support frame 30. The cleaning brush 21 is above the screen 31. A side opening 11 is provided on the tube wall of the tube body 10 near the support frame 30. A side plate 111 is rotatably connected to the side opening 11. Perforated plates 112 are fixed on both the tube body 10 and the side plate 111. Pins 113 are inserted into the two perforated plates 112. A limiting block 14 is provided inside the tube body 10. A positioning groove is opened at the bottom of the support frame 30 corresponding to the limiting block 14. A drain outlet is opened on one side of the tube body 10. A row of needles 13 for cleaning the cleaning brush 21 is rotatably connected inside the tube body 10 near the drain outlet. The row of needles 13 is controlled by a motor. The row of needles 13 rotates and combs the cleaning brush 21, and carries out the impurities in the cleaning brush 21. A ash discharge funnel 40 is installed at the drain outlet. The ash discharge funnel 40 is integrally formed with a locking block 41. The ash discharge funnel 40 is locked at the drain outlet by the locking block 41.

[0026] When the produced calcium hydroxide falls onto the screen 31, it is filtered and purified by the screen 31, and the impurities mixed in the calcium hydroxide are filtered out. The cleaning brush 21 runs to clean the impurities accumulated on the screen 31. The cleaning brush 21 sweeps the impurities to the drain port and discharges them through the ash discharge funnel 40. The rotating needle 13 combs the cleaning brush 21 and carries out the impurities in the cleaning brush 21, reducing the impurities hidden in the cleaning brush 21.

[0027] In summary, this embodiment of the utility model uses an electric slide table 12 to drive the cleaning brush 21 to clean the screen 31 and, in conjunction with the needle bar 13, to promptly remove impurities hidden in the cleaning brush 21, thereby improving the overall filtration and purification efficiency. The side opening 11 and the limiting block 14 facilitate the replacement of the screen 31 and accurately position the screen 31.
