Description
Technical field
The present invention relates to a kind of mixing plant, especially a mixing bowl of cold-regeneration stirring apparatus for asphalt mixture.
Background technology
Cold-regeneration stirring apparatus for asphalt mixture is the mixing apparatus that is used to handle flexible pavement milling material, and a mixing bowl is the heart component of this equipment.Milling material, water, cement, stone flour and mulseal fully stir in a mixing bowl, become qualified bituminous mixture.Old-fashioned a mixing bowl inner chamber is that two semicylinders intersect and to form, the upper end is a charging aperture, the lower end is a discharging opening, such a mixing bowl can only be quantitative stirring, stir the back from the discharge port end blanking, feed that can not be continuous, in actual engineering, receive very big restriction, this a mixing bowl posts abrasion-proof backing block on the inwall of cylinder body simultaneously, the stirring blade acts directly on the abrasion-proof backing block all materials is fully stirred during stirring, because very close to each other between blade and the liner plate, all materials have all participated in stirring, so the material stirring is comparatively even.The a mixing bowl cavity is not only complex-shaped, and manufacture difficulty is relatively large, and needs to use abrasion-proof backing block, has increased cost of production, and the user in use must regularly replace abrasion-proof backing block, has also increased use cost.
Summary of the invention
Technical problem to be solved by this invention is at the deficiencies in the prior art, and a kind of stirring cylinder of cold-regeneration stirring apparatus for asphalt mixture of continuous feeding is provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of a mixing bowl of cold-regeneration stirring apparatus for asphalt mixture, comprise cylinder body and be arranged on charging aperture and discharging opening on the cylinder body, in cylinder body, also be provided with two rotating shafts, in the axial interval that equates of two shafts, along inboard wall of cylinder block radially, evenly be provided with at least 3 respectively and stir blade apparatus, described stirring blade apparatus comprises stirring blade and handle of a knife, one end of described handle of a knife is fixed on the shaft, described stirring blade is fixed on the other end of handle of a knife, described charging aperture is arranged on the axial end A end top of cylinder body shaft, described discharging opening is arranged on the axial other end B of cylinder body shaft end below, the plane of described stirring blade and the axial line of the shaft α that has angle.
The radius of gyration of described stirring blade apparatus is 0.65～0.78 with the ratio of two shaft center to center distance, and described angle α is 35 °～50 °.
On described shaft, also be provided with reverse stirring blade apparatus, described reverse stirring blade apparatus along inboard wall of cylinder block radially, equally spaced be arranged on and stir between the blade apparatus, described reverse stirring blade apparatus comprises reverse stirring blade and handle of a knife, one end of described handle of a knife is fixed on the shaft, described reverse stirring blade is fixed on the other end of handle of a knife, the blade plane of described reverse stirring blade and the axial line of the shaft β that has angle.
Described angle β is 120 °～140 °.
The lower end of described cylinder body also is provided with Dump gate, and a Dump gate opening device is connected with it; Described Dump gate opening device comprises hydraulic jack, piston rod holder, cylinder tail holder, support; Described piston rod holder is fixed on the Dump gate, and described cylinder tail holder is fixed on the support, and described support is fixed on the lower end of cylinder body; The piston rod head of described hydraulic jack and piston rod holder are hinged, and the afterbody of described hydraulic jack and cylinder tail holder are hinged.
Compared with prior art, the present invention has following advantage:
1, the charging aperture of cylinder body of the present invention and discharging opening are arranged on cylinder body and prolong the axial two ends of shaft, stirring blade and shaft axioversion also has angle, after the stirring material enters from charging aperture, under the stirring of the stirring blade that tilts, be mixed output to the other end from an end of shaft, in the process that stirs, stir the material mixing and finish simultaneously, can realize continuous feeding.
2, in order to finish good mixed effect and output continuously, the angle that stirs blade and shaft is 35 °～50 °, makes the stirring material obtain the well-beaten while, under the effect of stirring the axial force that blade produced, a motive force that moves forward is arranged again.
3, the radius of gyration of stirring blade apparatus of the present invention is 0.65～0.78 with the ratio of two shaft center to center distance, can make the radius of gyration that stirs blade apparatus on two shafts interlaced, make and stir fully stirring of material, do not stay the dead angle, stir material and can obtain best mixing quality.
4, stir material for more sufficient mixing, reverse stirring blade apparatus also is installed on shaft, oppositely stirring blade plate plane and the axial angle β of shaft are 120 °～140 °.Make and stir material positive and negative two, increased the agitation stroke of stirring material and the friction between the stirring material, can allow like this stir to expect to reach more fully and mix, guaranteed the uniformity that pitch stirring material mixes to cross flow one.
5, the present invention is provided with Dump gate in the cylinder base of a mixing bowl, and Dump gate has hydraulic jack control to open, and is beneficial to and realizes control automatically, makes things convenient for the cleaning clout after the user produces end, and can alleviate working strength of workers.
6, the stirring linear velocity of stirring blade reaches 4.5m/s (general a mixing bowl is 3m/s), is in the optimum speed zone that " boiling " stirs, and can make bituminous mixture obtain best mixing quality.
7, a mixing bowl of the present invention need not abrasion-proof backing block, at the bottom of stirring blade and a mixing bowl, leave certain clearance, during stirring, elder generation's " punishment in advance " is promptly at gap inner stuffing material, and inserts is not participated in stirring in the stirring dead band, does not form logistics yet, so just avoided material to flow to the wearing and tearing of a mixing bowl inwall, can not influence simultaneously yet and stir the quality that material stirs, compared with prior art, provide cost savings.
