Description
Technical field
The utility model relates to drying plant partial structurtes design field in paper technology, specifically, relates to a kind of dryer scraper device with vacuum cleaning mechanism.
Background technology
In paper, paper or cardboard dry is generally that the drying section at paper machine completes.The drying section of paper machine is generally comprised of the logical cylindric drying cylinder of steam and the dry net of coated drying cylinder and some deflector rolls in several, the interior steam heat of drying cylinder conducts to drying cylinder cylinder and dries in the face of being attached at the l Water Paper page of cylinder face, the dry net of coated drying cylinder makes wet web be adjacent to cylinder face and reduces l Water Paper distortion, dry net rotates and does without end motion with drying cylinder, and l Water Paper page enters coiling process after several drying cylinder cylinder faces are dried the moisture that reaches technological requirement.
In Dryer Section of Paper Machine, there are two kinds of situations: the one, paper machine overhauling or shutdown are more than two days, and drying cylinder cylinder face can produce iron rust and dust more or less, and downtime is longer, and iron rust and dust are more; The 2nd, l Water Paper page has a small amount of paper hair in the process of drying through drying cylinder or filler, sizing material etc. come off and adhere to drying cylinder cylinder face (meeting having through drying cylinder cylinder face high-temperature heating becomes black or rust) from wet paper surface.Drying cylinder cylinder face is installed dryer scraper sheet the iron rust or dust or the paper scrap etc. that adhere to cylinder face is struck off.The above-mentioned spot impurity scraping off builds up at doctor blade edge place, if wing is because of wearing and tearing or after being out of shape and when the subsides of drying cylinder cylinder face are tight, the spot impurity scraping off will be brought into from the gap of wing and cylinder face between opposite side cylinder face and l Water Paper page and adhere to paper surface and form spot impurity, if the spot impurity therefore scraping off via wing has accumulation to remove in time.Because of paper machine fabric width wider, staff cleaning difficulty, generally that a compressed air hose is bundled on the stock that a root elevator is straight, cylinder blows off with high velocity air one by one, but blow afloat being scattered that the spot impurity that comes can be blown everywhere, what have adheres on paper and causes a part of Paper or cardboard to scrap with regard to having dropped on again between drying cylinder cylinder face and l Water Paper page and dry net.

Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the local enlarged diagram of A portion in Fig. 1;
Fig. 3 is the assembly structure schematic diagram of wing and vacuum cleaning mechanism.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Embodiment: referring to Fig. 1, Fig. 2, Fig. 3.
A kind of dryer scraper device with vacuum cleaning mechanism, comprise wing 1, described wing 1 is fixed on drying cylinder 3 tops by scraper fixed mount 2, also comprise vacuum cleaning mechanism, described vacuum cleaning mechanism comprises suction pipe 4 and vacuum device, described suction pipe 4 is fixed on the top of described wing 1 and laterally extending on the length direction of described wing 1, as shown in the figure, between suction pipe 4 and wing 1, by bolt 12, be fastenedly connected, the sidewall of described suction pipe 4 has suction inlet 5 in the direction towards wing 1 blade, one end sealing of described suction pipe 4, the other end is provided with aspirating hole 6, one side of described aspirating hole 6 is communicated with described suction inlet 5, opposite side is communicated with described vacuum device.
Described suction inlet 5 above wing 1 be parallel to the direction of blade laterally extending and and the blade of wing 1 between there is gap.
The suction inlet 5 of horizontally set is parallel with blade direction, has guaranteed that on blade, the dirt impurity of each position can enter suction inlet 5 smoothly.
Described vacuum device comprises vavuum pump (not shown) and vacuum dust tank 7, the middle part of described vacuum dust tank 7 is provided with screen pack 8, described screen pack 8 is divided into upper-part centralized air chamber 14 and bottom dust storage chamber 15 by the inner chamber of vacuum dust tank 7, described aspirating hole 6 is communicated with the dust storage chamber 15 of described vacuum dust tank 7, described collection chamber 14 is connected with vavuum pump, and the bottom of described dust storage chamber 15 is provided with sewage draining exit 13.
