A kind of tea grounds shingle machine
The utility model is related to tea grounds dehydration technique fields, and in particular to a kind of tea grounds shingle machine.
Present tea processing enterprise mostly realizes continuous slurry mask work using screw expeller, not only slurry
Separating effect is preferable, and substantially increases production efficiency.
In continuous production process, by the rotation of main shaft, the rotation of helical-blade is driven, to push tea grounds in filter screen
Cylinder internal helicoid advances, and generates squeezing action, squeezes out the tea extract in tea grounds.
But in place of Shortcomings, during screw extrusion, filtering net cylinder is easy to happen blocking, the reason is that granularity
More than the inner surface that the tea grounds in filter opening aperture is attached to filtering net cylinder under the action of extruding force, and filter opening is covered, and only
Can be cumulative, it gets deeper, causes the water permeable area of entire filtering net cylinder constantly to reduce, eventually reduce dehydration efficiency.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of tea grounds shingle machines, by clear
Part is swept to clean filtering net cylinder inner surface in time, with reduce tea grounds filtering net cylinder inner surface stack probability, to anti-
The only continuous reduction of filtering net cylinder water permeable area, finally improves dehydration efficiency.
To achieve the above object, the utility model provides following technical solution：A kind of tea grounds shingle machine, including outer barrel with
And for conveying tea grounds into the conveying assembly in outer barrel, outer barrel both ends have inlet port and outlet port, are equipped in outer barrel
Filtering net cylinder is provided with several first filter openings on filtering net cylinder, and gradual along the diameter of feed inlet to discharge port direction filtering net cylinder
Become smaller；It is equipped in filtering net cylinder and the drive component that driving spindle rotates is installed on the outside of main shaft and outer barrel, it is solid on main shaft periphery wall
Surely there are the gap settings such as the outer periphery of helical-blade and helical-blade and filtering net cylinder inner wall；Sky between the outer barrel and filtering net cylinder
Gap is to be communicated with outlet pipe in discharging chamber and discharging chamber, is equipped on the outer periphery of helical-blade several for cleaning in filtering net cylinder
The cleaning item of wall, and length direction of the cleaning item along helical-blade outer periphery is arranged.
By using above-mentioned technical proposal, the tea grounds in filtering net cylinder moves under the drive of helical-blade towards discharge port,
Along the tea grounds direction of motion, the space between main shaft and filtering net cylinder is smaller and smaller, then extruding force is increasing, tea extract from
It is forced out in tea grounds, to play the role of shingle dehydration.
In rotation process, cleaning item can sweep the inner wall of filtering net cylinder helical-blade simultaneously, will be covered in the
Tea grounds on one filter opening is scraped off from the first filter opening, with reduce tea grounds filtering net cylinder inner surface stack probability, to prevent
The continuous reduction of filtering net cylinder water permeable area, finally improves dehydration efficiency.
The utility model is further arranged to：It is detachably communicated with screen pipe on the outlet pipe, is installed in screen pipe
There is strainer again and offer the second filter opening on strainer again, the aperture of the second filter opening is less than the aperture of the first filter opening.
By using above-mentioned technical proposal, the bigger tea grounds of a part of granularity is blocked in filtering net cylinder, and another
Granularity smaller tea grounds in part can then be got into the first filter opening, finally will be with tea extract due to the relationship of internal pressure
By the first filter opening and enter in screen pipe, and the strainer again in screen pipe effectively to the thin tea grounds in this part can stopped
Filter, it is final to improve the quality of tea extract, and extract more dehydration tea grounds.
The utility model is further arranged to：The strainer again is cylindrical in shape and includes barrel and cylinder bottom, barrel and filtering
The inner wall gap setting of pipe.
By using above-mentioned technical proposal, tubular strainer again is more preferable than the filter effect of planar strainer again, because
For the filter area bigger of on the one hand tubular strainer again, on the other hand the filtering surface of the bowl wall portion of strainer is in perpendicular again
Straight state, then thin tea grounds be not easy under the effect of gravity product be attached on the second filter opening of barrel, to improve filter efficiency.
The utility model is further arranged to：The screen pipe is provided with buckling groove and buckling groove edge close to outlet pipe one end
Screen pipe is axially opened on the inner wall of screen pipe, and barrel upper end is fixed with for being clamped the fixture block into buckling groove.
By using above-mentioned technical proposal so that strainer is removably connected to screen pipe again, convenient better to strainer again
It is cleared up, to reuse.
The utility model is further arranged to：The upper end of the barrel is fixed with hand-held rod.
By using above-mentioned technical proposal, strainer again is conveniently taken out.
The utility model is further arranged to：The driving component include variable-frequency motor, for connect variable-frequency motor and
The shaft coupling of main shaft.
By using above-mentioned technical proposal, the tea grounds moisture content of different cultivars tealeaves is different, and same shingle frequency has
Tea grounds just do not extract fully, cause invisible loss, and variable-frequency motor can control helical-blade rotational frequency, can make different
Tea grounds more can be extracted adequately, and production yield is improved, and reduce loss.
The utility model is further arranged to：It is fixed with reinforcing rib on the helical-blade.
By using above-mentioned technical proposal spiral is then acted on since the rotational frequency of helical-blade can always change
The variation of active force on leaf is often also bigger, reduces the intensity of helical-blade to a certain degree.And reinforcing rib can then enhance spiral shell
The intensity of vane extends its service life.
The utility model is further arranged to：The discharging chamber bottom angled is arranged and outlet pipe connection is in discharging chamber
By using above-mentioned technical proposal, the tea extract of discharging intracavitary is enable more completely to export into outlet pipe.
The utility model has the following advantages：
1, filtering net cylinder inner surface is cleaned in time by cleaning item, it is folded in filtering net cylinder inner surface to reduce tea grounds
Long-pending probability finally improves dehydration efficiency to prevent the continuous reduction of filtering net cylinder water permeable area；
2, the strainer again in screen pipe can carry out blocking filtering to the thin tea grounds across the first filter opening, final to improve tea extraction
The quality of liquid, and extract more dehydration tea grounds.
