Abstract
The present utility model discloses a rotary drum enclosing valve of drum-like vacuum washing engine comprising a valve body. An installing hole base connecting with the valve base is provided at outer edge of the valve body, a sealing surface for seal contacting with the rotary drum end surface is provided at inner edge of the valve body. A convex hollow cavity with respect to the plane of the sealing surface is arranged on the valve body. The installing hole base is disposed at outer edge of the hollow cavity side wall. The valve body is made of fiberglass. A steel skeleton provided on the valve body is disposed in the valve body member. The cavity of this utility model makes the vacuum degree of the passages and chambers corresponding with the rotary drum destroyed, and compressed air is introduced into corresponding chamber by the hollow cavity. The paste is applied directly with a force perpendicular to surface tangent line to be raised up for stripping. Thus, the paste can be stripped thoroughly, the difficult paste stripping problem can be solved. Moreover, the utility model has improved production, reduced cost, improved benefit, unease pasting net in concrete use, and ensures normal operation of production line.
Description
Technical field
The utility model relates to a kind of drum-type vacuum washer rotary drum draught excluder.
Background technique
At present, employed plane valve in the vacuum washer of being produced at home and abroad, the sealing surface that the inboard of valve body contacts with rotary drum end face liquid sealing is a pure flat structure, its use only is to cut off the crossfire of runner and compartment vacuum and atmosphere in stripping slurry district, thereby makes air bells doctor peel off the rotary drum top layer to slurry.Yet, in this course, even the degree of vacuum in rotary drum inner flow passage and the compartment is retained, it is not thorough that this just makes slurry peel off, even difficulty is peeled off, influence stripping slurry effect, reenter cell body under causing scraper, make the whole piece pulping production line be in improper operating condition.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of the district at the stripping slurry makes slurry peel off drum-type vacuum washer rotary drum draught excluder completely.
For solving the problems of the technologies described above, the utility model comprises valve body, the outside of valve body has the mounting hole seat that is connected with valve seat, the inboard of valve body has the sealing surface that contacts with rotary drum end face liquid sealing, its structural feature is to be provided with a cavity with respect to plane, sealing surface place evagination on valve body, and described mounting hole seat is positioned at the outside of this cavity sidewalls.
Described valve body is made by glass fibre reinforced plastic material.
Be provided with Steel Skeleton on valve body, this Steel Skeleton places in the valve body body.
Angle [alpha] 3 is between 75 °-85 ° between fan section, described cavity place.
The degree of depth A of described cavity is 60mm-85mm.
Described valve body has an arc transition district in rotary drum sense of rotation the place ahead, and its radius R is between 150-220mm, and angle [alpha] is between 8 °-15 ° between the fan section, place.
After adopting said structure, owing on valve body, be provided with a cavity with respect to plane, sealing surface place evagination, this cavity makes degree of vacuum destruction in runner corresponding in its rotary drum and the compartment, and pressurized air is led to its corresponding compartment by this cavity, directly give power of slurry perpendicular to surperficial tangent line, the slurry picking-up is peeled off, the stripping slurry thoroughly like this, thereby solve the difficult problem of stripping slurry, and raising output reduces cost, and increases benefit, also be difficult in concrete the use sticking with paste net, make production line normal.And the arc transition district is set, and can form the natural filtration district, it is thick that the slurry layer is hung, and improves output equally, increases benefit.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is center deployment figure of the present utility model;
Fig. 2 is the sectional view along place, Fig. 1 mounting hole seat center standard pitch circle;
Fig. 3 is drum body air flows schematic representation.
Embodiment
With reference to accompanying drawing, this drum-type vacuum washer rotary drum draught excluder comprises valve body 3, valve body 3 is fan-shaped anchor ring, its inner arc radius R 3 is between 300mm-360mm, outer arc radius R 3 is between 580mm-700mm, valve body 3 is made by glass fibre reinforced plastic material, increase wear resistance, the outside of valve body 3 has the mounting hole seat 1 that is connected with valve seat, mounting hole seat 1 is two, the radius R 2 of place, mounting hole seat 1 center standard pitch circle is between 450mm-530mm, angle [alpha] 5 is between 48 °-52 ° between two mounting hole seats, 1 shared fan section, be valve body 3 fixed installation angles, the inboard of valve body 3 has the sealing surface 4 that contacts with rotary drum end face liquid sealing, sealing surface 4 is in order to cut off the crossfire of runner and compartment vacuum and atmosphere, cut with rotary drum and seal, concrete sealing is that the moisture film by 0.2mm-0.5mm reaches, on valve body 3, be provided with Steel Skeleton 2, this Steel Skeleton 2 places in valve body 3 bodies, that is glass fibre reinforced plastic material coats, increase the intensity of valve body 3, be provided with a cavity 5 with respect to plane, sealing surface 4 place evagination on valve body 3, described mounting hole seat 1 is positioned at the outside of these cavity 5 sidewalls, angle [alpha] 3 is between 75 °-85 ° between fan section, cavity 5 place, and the degree of depth A of cavity 5 is 60mm-85mm.At the afterbody of valve body 3, that is have an arc transition district in rotary drum sense of rotation the place ahead, its radius R is between 150-220mm, and angle [alpha] is between 8 °-15 ° between the fan section, place.Angle [alpha] 4 is between 110 °-130 ° between whole valve body 3 shared fan sections.Among Fig. 1, interval angle [alpha] 2, α 3 are between 28 °-32 °, and α 6 is between 8 °-12 °.Its working principle is referring to Fig. 3, air bells doctor 9 contacts with the slurry layer of rotary drum outer surface, and pressurized air 9 (2000Pa) enters α 2 intervals by the α interval, enters compartment 7 by runner 6 again, give power that makes progress of slurry layer of drum surface, paper pulp is peeled off from drum surface.Simultaneously 7-8 runner 6 is communicated with between fan section, cavity 5 place, pressurized air is entered in the runner 6,, starch difficult problem thereby solve stripping to destroy the degree of vacuum of bulging body inner flow passage and compartment.
