Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.

As shown in fig. 1-4, the utility model provides a technical solution: the utility model provides a calcium carbonate screening plant, includes box 1 and two landing legs that are fixed in the 1 bottom of box, and the bottom intercommunication of box 1 has out feed cylinder 11, and the intercommunication has the inlet pipe that extends to in the box 1 on the

box

1, 1 internal rotation of box is connected with two bull sticks 2 that are the level setting, two the cover is equipped with along with bull stick 2 pivoted transmission band 3 on the bull stick 2, evenly distributed has a plurality of perforation on the

transmission band

3, 3 inboards of transmission band be equipped with be located between two bull sticks 2 and with 1 inner wall fixed connection's of box screening board 6, evenly seted up a plurality of screening holes on the screening board 6, be equipped with on the box 1 and be located the screening mechanism that 3 below of transmission band was used for sieving calcium carbonate once more.

In the above scheme, as shown in fig. 1, fig. 2 and fig. 3, screening mechanism is including being fixed in the box 1 and extending to the frame 7 that gathers materials of box 1 outside, box 1 side is fixed with the housing 8 that is located gathering frame 7 below, housing 8 internal fixation has the screening section of thick bamboo 9 that is vertical setting, evenly distributed has a plurality of holes on the screening section of thick bamboo 9, housing 8 internal fixation has drive arrangement 13, just be fixed with the spiral conveying mechanism 10 that extends to in the screening section of thick bamboo 9 in drive arrangement 13's the pivot, the intercommunication has the conveying pipeline that runs through housing 8 and screening section of thick bamboo 9 and be linked together on the frame 7 that gathers materials. The hole diameter on the screening section of thick bamboo 9 is the biggest, secondly be the screening hole on the screening board 6, last perforation on the transmission band 3, after the calcium carbonate of great particle diameter is carried to frame 7 that gathers materials on the transmission band 3 in, calcium carbonate then gets into in the screening section of thick bamboo 9 through the conveying pipeline, then drive arrangement 13's pivot drives the defeated material mechanism 10 rotation of spiral, promote the calcium carbonate in the screening section of thick bamboo 9, the less calcium carbonate of particle diameter then drops outside the screening section of thick bamboo 9 through the hole, the great calcium carbonate of particle diameter then passes through the transport of the defeated material mechanism 10 of spiral, at last by carry outside the screening section of thick bamboo 9, the effect of screening calcium carbonate once more has been reached. The spiral conveying mechanism 10 is a structure in which a spiral conveying blade is disposed outside a common rotating shaft, and is commonly found in a packing auger, and therefore, is not described herein.

As a preferred embodiment, as shown in fig. 2, two baffles 4 for laterally blocking the conveyor belt 3 are fixed in the box 1, and two scrapers 5 are fixed between the two baffles 4. Baffle 4 can block 3 sides of transmission band, prevents that calcium carbonate from dropping from the side of transmission band 3, and scraper blade 5 then can be spread the calcium carbonate of piling up on transmission band 3, and two scraper blade 5's length is different simultaneously, can be better will pile up calcium carbonate together and spread, make the perforation on transmission band 3 that calcium carbonate can be better sieve.

As a preferred embodiment, as shown in fig. 2, a rotating rod 2 located at one side inside the case 1 is driven by a motor. The motor provides power to drive the rotating rod 2, so that the transmission belt 3 can better sieve calcium carbonate.
