Summary of the invention

The object of the present invention is to provide a kind of tea screening device, make the breakneck acceleration of tealeaves fast, effective.

Tea screening device in this programme, include sieve body, described sieve becomes cylindrical, it is horizontally disposed with vertically, the closed at both ends of sieve, the bottom of sieve is provided with the husky net of sieve, sieve husky side off the net and be provided with sandstone holder, sandstone holder becomes truncated cone-shaped, fix with screen side walls above it, screen side walls is divided into two parts along the perpendicular bisector running through axis, wherein a side-lower is tangentially provided with inverted T-shape feed pipe, the upper opening of feed pipe is charge door, another opening is blast orifice, screen side walls opposite side is set to screen cloth, bottom-up three screening areas being divided into the steps increase of sieve aperture of screen cloth, each screening area arranged outside has the container shrouded on corresponding screen cloth, the bottom of container is provided with the husky net of the second sieve.

The tea screening device of this programme is adopted to have following advantage: the shape due to sieve becomes anti-down cylindrical, can rotate around screen side walls after tealeaves enters with the wind below screen side walls, first due to heavier sandstone, first the sandstone holder sieving husky side off the net can be fallen into, then more a little bit smaller tealeaves due to wind surface less, can screen in the screening area that screen cloth bottom sieve aperture is less and enter corresponding container, then larger tealeaves due to wind surface larger, can continue to move upward, then screening area up screens, last larger tealeaves can in the end screen a screening area, due to have employed a sieve, in screening process, tealeaves can be separated according to different sieve apertures automatically, do not need the power of other mechanical presses, so screening effect is better, and breakneck acceleration is compared to the screening mode of traditional multiple sieves, better effects if.

Preferably, the bottom on described container is also provided with discharging opening, because the tealeaves screened can be deposited in the bottom of container under gravity, is therefore arrange to make container discharge more easy like this.

Preferably, described feed pipe is provided with heating wire near the position of blast orifice, and first the wind that such blast orifice is come in can be heated up by electric-heating-wire-heating, wind after intensification is when blowing tealeaves, certain drying can be carried out to it simultaneously, thus avoid tealeaves to bond, improve screening effect further.

Preferably, be provided with the lid of a sealing above described charge door, such arranging can make, upon completion of the addition by sealing of lid charge door, to avoid unnecessary wind to spill from charge door, is conducive to the screening effect improving whole screening plant.
