Background
Pulping is the first process in the papermaking process, and the quality of paper pulp directly influences the subsequent production and the quality of finished products; at present, pulpers are adopted for pulping, raw materials are crushed and uniformly stirred to form paper pulp through high-speed rotation of crushing blades, however, rotating shafts of the pulpers are located in the center, so that pulp in a central area can be sufficiently crushed, but the pulp on the outer side cannot be effectively crushed due to the fact that the pulp is far away from the crushing blades, and accordingly the pulp is crushed unevenly; although some improved pulpers are provided at present to solve the problem, the mode of mounting impellers for pushing the pulp inwards on the side wall of the charging barrel is mostly adopted, each impeller needs to be driven independently, the structure is complex, the equipment cost is increased, and the mode also damages the integrity of the side wall of the charging barrel and is easy to leak pulp, so the practicability is not high; in addition, the current pulper also has the problem of inconvenient cleaning of the filter screen.
SUMMERY OF THE UTILITY MODEL
To the above-mentioned condition, for overcoming prior art's defect, the utility model provides a papermaking pulping device, the effectual inhomogeneous problem of present pulper pulping of having solved.
The technical scheme for solving the problem is that the papermaking pulping device comprises a columnar charging barrel, wherein the top of the charging barrel is provided with a charging opening, the bottom of the charging barrel is provided with a discharging opening, the bottom of the side wall of the charging barrel is provided with a slag discharging opening, and the discharging opening and the slag discharging opening are both provided with switch valves; the axis department of feed cylinder installs a vertical pivot, and the upper end of pivot stretches out the feed cylinder and just is connected with the motor outward, and fixed mounting has a plurality of upper and lower interval arrangement's broken blade in the pivot, and the outer circumference equipartition of pivot has a plurality of risers, and the outside edge of every riser all is pressed close to with the inner wall of feed cylinder, and the outside edge of every riser all inclines to clockwise, and every riser all fixes in the pivot through the connecting rod.
The utility model discloses can guarantee that the thick liquids in the feed cylinder are by even breakage, improve crushing effect, simple structure moreover, reduce equipment cost, in addition, through the impurity on the clearance filter screen that the scraper blade can be quick, convenient to use.
Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1 to 3, the utility model comprises a cylindrical material cylinder 1, a feeding port 2 is arranged at the top of the material cylinder 1, a discharging port 3 is arranged at the bottom of the material cylinder, a slag discharging port 4 is arranged at the bottom of the side wall of the material cylinder 1, and switch valves 5 are respectively arranged on the discharging port 3 and the slag discharging port 4; a vertical pivot 6 is installed to the axis department of feed cylinder 1, and the upper end of pivot 6 stretches out feed cylinder 1 and just is connected with motor 7 outward, and fixed mounting has a plurality of upper and lower interval arrangement's crushing blade 8 in the pivot 6, and the outer circumference equipartition of pivot 6 has a plurality of risers 9, and the outside edge of every riser 9 all is pressed close to with the inner wall of feed cylinder 1, and the outside edge of every riser 9 all inclines to clockwise, and every riser 9 all fixes in pivot 6 through connecting rod 10.
Feed cylinder 1 in install the horizontally filter screen 11 that is located its bottom, the lower extreme of pivot 6 is fixed with the arc scraper blade 12 of a plurality of circumference equipartitions, the downside of a plurality of arc scraper blades 12 all laminates with filter screen 11, arc scraper blade 12 can scrape the impurity on the filter screen 11 to the outside along with pivot 6 clockwise turning.
The lower end of the charging barrel 1 is conical with a downward small end, and the discharge port 3 is positioned at the bottommost part of the conical shape.
And a feeding hopper 13 is arranged on the feeding opening 2.
When the utility model is used specifically, the switch valve 5 of the discharge port 3 and the slag discharge port 4 is firstly closed, then raw materials to be crushed, water and various additives are added into the charging barrel 1, then the motor 7 is started, the motor 7 drives the rotating shaft 6 to rotate, the rotating shaft 6 drives the crushing blade 8 and the plurality of vertical plates 9 on the rotating shaft to rotate clockwise, the crushing blade 8 crushes the raw materials in the central area, and simultaneously, the outer sides of the plurality of vertical plates 9 all incline clockwise, so the vertical plates 9 rotate to shovel the slurry outside the charging barrel 1 to the central area and be crushed by the crushing blade 8, thereby the raw materials in the charging barrel 1 can be effectively crushed; in addition, the rotating shaft 6 rotates to drive the arc-shaped scraping plates 12 at the lower ends of the rotating shaft to rotate clockwise, the arc-shaped scraping plates 12 can stir the slurry at the bottom of the charging barrel 1, the deposition of the slurry at the bottom is prevented, and the uniformity of crushed slurry is ensured.
After pulping is finished, the motor 7 is closed, the switch valve 5 on the discharge port 3 is opened, paper pulp is discharged from the discharge port 3 through the filter screen 11, and raw materials and impurities which are not fully crushed are filtered by the filter screen 11 and are left on the surface of the filter screen 11; after the thick liquids had been arranged, close the ooff valve 5 of discharge gate 3, open the ooff valve 5 of row cinder notch 4, restart motor 7, add water in to feed cylinder 1 simultaneously, pivot 6 drives arc scraper blade 12 clockwise rotation, and arc scraper blade 12 scrapes the impurity on the filter screen 11 to the outside then along with rivers from row cinder notch 4 discharge, after the impurity is discharged completely, open the ooff valve 5 of discharge gate 3 with the interior remaining water of feed cylinder 1 clean can.
The utility model can scrape the slurry outside the charging barrel 1 to the middle through the plurality of obliquely arranged vertical plates 9, and the arc-shaped scraper 12 can prevent the slurry from depositing at the bottom, thereby ensuring that the slurry in the charging barrel 1 is uniformly crushed, improving the crushing effect, and only needing one driving shaft and one driving motor 7, and having simple structure and reducing the equipment cost; in addition, the impurity on the filter screen 11 can be cleaned rapidly through the scraper blade, and the use is convenient.
