Abstract
The utility model discloses a rotor type sealing disk of a concrete sprayer. The rotor type sealing disk of the concrete sprayer comprises sealing disk bodies, inside plane sealing rings, outside plane sealing rings, a feeding sweeper and the like, wherein inside plane sealing rings and outside plane sealing rings are respectively arranged inside and outside a rotor material cavity; and annular grooves which are used for fixing cylindrical rotor dust-collecting covers are formed on outer circles of sealing disk bodies. The rotor type sealing disk of the concrete sprayer is long in service life, good in sealing effect and low in friction resistance and required driving power, and sealing disk bodies can be repeatedly repaired for use after being abraded.
Description
Technical field
The utility model relates to a kind of concrete sprayer of gunite construction operation, especially a kind of rotator type concrete sprayer seal disc.
Background technology
The end face of rotor is arranged and be pressed on to rotator type concrete sprayer seal disc; Rotor has the material chamber that one group of annular is uniformly distributed with; Fill up the rotor rotation in whitewashing material material chamber during work; Seal disc is fixed, and requires in rotor rotation process, to expect that the whitewashing material in the chamber can be from the face leakage of rotor under the blast effect.Existing seal disc is to constitute by the sealing offset plate that is used to seal with as the steel sole plate of substrate bonding; Because the end face of sealing offset plate and rotor is made fricting movement during spraying machine work; Sealing offset plate on the seal disc is very easily wearing and tearing under thrust and concrete acting in conjunction, thereby cause dust to leak.Owing to can't repair utilization again behind the sealing offset plate surface abrasion, can only scrap together with steel sole plate integral body, therefore cause bigger waste.In order to guarantee that the effective sealing that seals offset plate must apply enough thrusts,, therefore need to consume bigger driving power, and fricative heat has limited the raising of rotor speed because the coefficient of friction of sealing offset plate is bigger.
Summary of the invention
The purpose of the utility model is to provide a kind of concrete sprayer seal disc; Prolonged the application life of seal disc, and sealing effectiveness is better, and the required driving power of the coefficient of friction of seal disc and rotor is littler; Rotor speed is higher, and can repeatedly repair use after the seal disc wearing and tearing.
The technical scheme of the utility model is: a kind of concrete sprayer seal disc; Comprise sealing disk body, arc charging aperture, air inlet port, residual air mouth, discharge gate; It is characterized in that: the sealing disk body is provided with interior sealed groove, the external seal groove reaches and its equipped inner side plane sealing ring, outside planar seal ring; The inner side plane sealing ring is arranged in the inboard in rotor material chamber, and outside planar seal ring is arranged in the outside in rotor material chamber.
The interior sealed groove of said sealing disk body and external seal groove are provided with residual pressure gas and dust are directed to the residual voltage compensating groove in residual air mouth and the rotor material chamber, to reduce gas leak and to prolong life-span of sealing ring.
The cylindrical of said sealing disk body is provided with the annular groove that is used for fixing the cylindrical rotor dust gathering arrester, can reduce the dust of concrete sprayer.
Said sealing disk body is scraped and is swept device being provided with charging near arc charging aperture place; Charging is scraped and is swept device and be made up of round rubber plate and volute spring; The round rubber plate can suitably exceed the seal disc working face under the free state under the extruding of volute spring; Charging is scraped and is swept device and can scrape the concrete of rotor material top of chamber and sweep extruding when rotor rotates, to reduce the wearing and tearing to the sealing disk body.
Said sealing disk body can adopt ordinary metallic material to make and adopt special process to carry out case hardening at the friction working surface of disk body and handle, also can wholely adopt hard wear-resistant material to make.
Said medial and lateral planar seal ring can be selected Y shape, O shape, rectangular seal for use or select other hermetically-sealed constructions such as combination sealing for use.
The effect of the utility model with advantage is: because inside and outside side plane sealing ring neither bears the end face thrust and also directly do not contact concrete, only bear the air seal function, thereby the sealing effectiveness of the more effective raising seal disc of ability and longer application life; Do not bear the air seal function owing to have the sealing disk body on hard, wear-resistant surface, only bear end face thrust and wear-resisting functions, thereby can prolong seal disc application life yet; Because the coefficient of friction of hard, wear-resistant sealing disk body is more much smaller than rubber tile, thereby can effectively reduce the driving power and the heat that rubs of spraying machine rotor, the rotating speed that can also further improve rotor sprays pulsation and increases emitted dose to reduce; Since can be repeatedly after the surface abrasion of sealing disk body exceeds standard processed cementation zone again, thereby need not to scrap immediately and practiced thrift cost; Because the cylindrical of sealing disk body is provided with annular groove, can be easily fixing cylindrical rotor dust gathering arrester, thereby can further reduce the dust of concrete sprayer.
