Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, in particular to a calcium carbonate ore screening device. Background Art

[0002] Calcium carbonate is an inorganic compound, commonly known as limestone, marble, etc. Calcium carbonate is neutral, basically insoluble in water, soluble in hydrochloric acid, it is one of the common substances on the earth, existing in rocks such as chalk, limestone, travertine, etc. It is a white solid, tasteless and odorless, with two forms: amorphous and crystalline. In the production of calcium carbonate ore, it is often necessary to screen calcium carbonate ores of different sizes so that calcium carbonate ores of different sizes can be easily processed and ground in the later stage. Most of the existing screening devices directly place the calcium carbonate ore on the screen and screen the calcium carbonate ore through the screen, but the larger particles on the screen will remain on the screen, which is not only easy to cause the screen to be blocked, but also requires regular recycling of larger particles, resulting in low screening efficiency.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figures 1 to 3The utility model provides a technical solution: a calcium carbonate ore screening device, comprising a base 1, on which a mounting seat 4, a first partition plate 2 and a plurality of second partition plates 7 are fixed, a swivel 3 is fixed on the second partition plate 7, a screening cylinder 8 is rotatably matched between the plurality of swivels 3, a plurality of first sieve holes 9, a plurality of second sieve holes 10 and a plurality of third sieve holes 11 are provided in the screening cylinder 8, a fixing rod 15 is installed between the plurality of swivels 3, bristles 17 are fixed on the fixing rod 15, and a baffle 6 is fixed on the first partition plate 2.

[0020] In this embodiment, the base 1 is an inclined structure, the screening drum 8 is inclinedly arranged on the upper side of the base 1, a motor 5 is fixed on the mounting seat 4, a rotating shaft 14 is fixed to the output end of the motor 5, the rotating shaft 14 is located in the screening drum 8, a plurality of plug rods 16 are fixed to one end of the rotating shaft 14, a slot is provided in the screening drum 8, the slot corresponds to the plug rod 16, the baffle 6 is rotatably connected to the rotating shaft 14, a feed port 12 is provided at one end of the screening drum 8, and a discharge port 13 is provided at the other end of the screening drum 8.

[0021] Specifically, when the calcium carbonate ore is screened, the calcium carbonate ore is fed into the screening drum 8 from the feed port 12, so that the calcium carbonate ore slides and is screened in the screening drum 8, and the motor 5 is started. The motor 5 drives the screening drum 8 to rotate through the rotating shaft 14, so that the screening speed can be accelerated, and then the larger calcium carbonate ore remaining in the screening drum 8 slides out from the discharge port 13 and falls on the base 1 under the guidance of the baffle 6. The calcium carbonate ore can be graded, screened and then collected, and the screening work efficiency is relatively high.

[0022] The fixing rod 15 is fixed to the upper side of the rotating ring 3 , and the bristles 17 are in contact with the screening cylinder 8 , and the bristles 17 are hard bristles.

[0023] Specifically, when screening, the screening cylinder 8 rotates, and the screening cylinder 8 contacts the bristles 17. As the screening cylinder 8 rotates, the bristles 17 brush the surface of the screening cylinder 8, or are directly inserted into the first sieve holes 9, the second sieve holes 10 and the third sieve holes 11 to clear the sieve holes, thereby preventing the first sieve holes 9, the second sieve holes 10 and the third sieve holes 11 from being blocked.

[0024] In particular, the apertures of the first sieve hole 9, the second sieve hole 10 and the third sieve hole 11 are increased successively, so that the graded screening of the calcium carbonate ore can be achieved, thereby improving the screening effect.

[0025] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
