Shtukaturam-professionals in the conditions of a modern major project extremely seldom should prepare a solution. It prepare on-line on rastvornyh knots. It can be the present factory of a solution serving at once the whole area of mass building. Can be and the local knot intended for needs of one platform. In any case of operation of preparation of a solution are carried out here by cars-rastvoromeshalkami (fig. 3). They happen different capacity - 40, 80, 150, 325 l and more, the principle of work is identical to all. Into a reception ladle load in advance measured materials, submit them to a mixing drum. Then from a special tank pour water in strictly certain quantity.
a Fig. 3. The scheme rastvorosmesitelja С-588 :
1 - a frame; 2 - the electric motor; 3 - a reducer; 4 - a traverse; 5 - lopastnyj a shaft; 6 - the bunker; 7 - a wheelbarrow; 8 - a footboard; 9 - a wheel
Weight Hashing carries out a special shaft with the blades, being in a mixing drum. The car is arranged so that the shaft rotates, and the drum remains motionless. Hashing lasts 2... 3 minutes After that through a special aperture in the drum bottom pour out a ready solution in the reception bunker.
Large rastvornye knots settle down always on any bolshem or smaller distance from building sites. A ready solution add in a proper place dump-body trucks-rastvorovozami.
All process of manufacture of works on major projects in areas of mass building is mechanised. On fig. 4 the scheme of complex mechanisation of plaster works is resulted.
In areas of not mass building often use mobile rastvorosmesitelnuju the installation mounted on automobile dvuhosnom the trailer (fig. 5). It put near to the finished house that is very convenient. Such installation can give in change to 20 m 3 a solution.
If the requirement does not exceed 5... 6 m 3 a solution in change, it is more favourable to use on priobektnom knot mobile rastvorotransportnuju installation of type С-250. Installation has rastvoromeshalku С-50 capacity of 80 l, the metal bunker, rastvoronasos С-251, type 0-16 compressor.
a Fig. 4. The scheme of complex mechanisation of plaster works :
1 - a tanker with izvestju; 2 - installation for limy milk; 3 - station for reception of a commodity solution; 4 - rastvorovoz; 5 - rastvoroprovod; 6 - the three-running crane; 7 - drawing of a ground and obryzga; 8 - drawing nakryvochnogo a layer; 9 - zatirka
This complete set use also directly on floors for solution giving to raspylitelnoj to an atomizer.
Speaking about mechanisms for solution preparation, it is necessary to mention two improvements.
a Fig. 5. Mobile shtkkaturnaja station on automobile dvuhosnom the trailer :
1 - a trailer platform; 2 - rastvorosmesitel С-220; 3 - rastvoronasos С-317; 4 - rastvoronasos С-251; 5 - kompresoor О-16 or О-38; 6 - the intermediate bunker; 7 - vibrosito; 8 - a control panel; 9 - a metalwork workbench; 10 - a dosing tank rastvorosmesitelja
It is developed small-sized rastvorosmesitel, convenient for solution preparation on a floor at a small field of operations. For a basis was it is taken rastvorosmesitel С-50. Has been replaced in it usual shesterenochnyj a reducer by the small worm, closed aluminium case. In rastvorosmesitele С-50 against sliding bearings lean a mixing drum and lopastnyj a shaft. Have taken out bearings for drum limits. It have reached at once two advantages: have removed from a shaft loading from weight of a drum and have excluded solution hit on bearings. The amalgamator EFFICIENCY has been raised also, term of its service is extended.
We rastvorosmesitel capacity for a business hour can give of 40 l 0,5... 0,7 m 3 a solution. The car is much easier, than С-50, is more compact - easily passes through ljubye'dveri. In it the engine by capacity 0,5 is used... 0,7 kw.
Happens that on building it is necessary to prepare two different solutions - limy and cement, and at the disposal of dressers there is only one rastvorosmesitel. How to be? To rastvorosmesitelju the narrow-gauge railway in length of 6 m. On it is laid two bunkers for different solutions go. If the limy solution at present is necessary to dressers, the bunker for the cement remove aside, adjust to rastvorosmesitelju the second bunker, pour out in it the prepared limy weight and submit it to a place of swapping of a solution on floors.
Giving on floors can be made by lifts in inventory container or rastvoronasosom through rastvoroprovody. Rastvoronasosy happen different productivity, for example С-232 pass 6 m 3 /ch, С-263 - 3 m 3 /ch. Range of transportation of weight across - 200 m, on a vertical - 30 m.
