Abstract
A kind of concrete mixing station aggregate heating means install multiple radiators in three sidewalls of feed bin, while install floor heating on feed bin ground；Using the hot water of boiler supplying as heating agent, the water inlet of heat supply pipeline is connected with the water outlet of boiler heating system for the radiator and floor heating.The ground of the present invention warms up radiator using the hot water of boiler supplying as heating agent, it is heated by the heat transfer type for radiating (main) and convection current (secondary) to feed bin, aggregate is heated and keeps the temperature at 15 DEG C~25 DEG C, which, which can meet, mixes and stirs needs.The method of the present invention is cheap, easily controllable.
Description
Technical field
The invention belongs to concrete mixing station constructive technology in winter, more particularly to a kind of concrete mixing station aggregate heating side
Method.
Background technology
According to relevant regulations, winter ready-mixed concrete should have certain out-of-machine temperature and molding temperature, to prevent coagulation
Native early freezc.To ensure the mixing temperature of concrete, it usually needs mixing water or aggregate are heated or will both be added
Heat, the heating temperature of aggregate are not to be exceeded 60 DEG C.
The content of the invention
The present invention provides a kind of concrete mixing station aggregate heating means, this method can be in qualified storehouse in roof insulating
Aggregate carries out heating and keeping suitable temperature, to meet concreting in cold-weather requirement.
As above conceive, the technical scheme is that：A kind of concrete mixing station aggregate heating means, it is characterised in that：
Multiple radiators in three sidewalls of feed bin are installed, while floor heating is installed on feed bin ground；The radiator and floor heating are equal
Using the hot water of boiler supplying as heating agent, the water inlet of heat supply pipeline is connected with the water outlet of boiler heating system.
The present invention buries floor heating below feed bin, and a certain number of radiators are installed on the wall around feed bin.
Ground warms up radiator using the hot water of boiler supplying as heating agent, by radiating the heat transfer type of (main) and convection current (secondary) to material
Storehouse is heated, and aggregate is heated and keeps the temperature at 15 DEG C~25 DEG C, which, which can meet, mixes and stirs needs.The method of the present invention is made
Valency is cheap, easily controllable.

Specific embodiment
A kind of concrete mixing station aggregate heating means, include the following steps：
1st, radiator is arranged.Such as Fig. 1, in three sidewalls of feed bin (feed bin is three face enclosings, be open on one side into and out of
Material), according to 1/5~6m2Standard installation radiator.Steel radiating fin common in the market may be selected in radiator, because of heat preservation
Space is larger in canopy, and size is chosen as 180cm × 60cm.
2nd, radiator is installed.First pacify inlet valve and back-water valve (BWV), the position of fixed pendant horizon rule measurement radiator will be warm
Whether gas piece is steadily placed, and valve connections and intake-outlet valve are linked together, put down using horizon rule measurement radiator
Directly, whether pipeline installation meets the requirements.Connector is tightened using pipe wrench reinforcing.Pressure testing：Close supervisor's connecting valve, turning off steam
Piece into back-water valve (BWV), test pressure should be 1.5 times of operating pressure, non-leakage for qualification with pressure testing 2~3 minutes.
3rd, floor heating is installed.Such as Fig. 2, after the completion of feed bin basement process, 10~15cm thickness C20 foam concrete is applied as exhausted
Thermosphere, isolation heat transfer downwards；Then layer of non-woven fabric base aluminum foil material is laid on it as reflectance coating, prevents downward spoke
Heat transfer is penetrated, heat is reduced and scatters and disappears, improve thermal effect.Selecting φ 100mm steel pipes, detour type is laid as geothermal heat pipeline, and reinforcement bar support stands, is solid
Fixed, pipeline center is apart from heat insulation layer top surface about 15cm.After pressure testing qualification, 30cm thickness C30 concrete foundations are poured, also may be used if necessary
To add one layer of reinforced mesh in bottom, compression strength is improved.
The present invention operation principle be：
1. radiator working method:The hot water burnt in boiler is transported to radiator by pipe-line system, and shed heat, makes
Atmosphere temperature rising in feed bin；
2. floor heating working method：Floor heating is equally using hot water as heating agent, in heating pipe internal circulation flow, is evenly heated ground
Face, by ground to radiate heat transfer type heat supply into feed bin of (main) and convection current (secondary).
3. two ways is combined, firing rate and effect are promoted, it is full so as to which the aggregate being deposited in feed bin be heated to
Sufficient winter mixes and stirs the suitable temperature of concrete needs, and continues to keep the temperature.
Claims (1)
1. a kind of concrete mixing station aggregate heating means, it is characterised in that：Multiple heating are installed in three sidewalls of feed bin
Piece, while floor heating is installed on feed bin ground；The radiator and floor heating are using the hot water of boiler supplying as heating agent, heat supply pipeline
Water inlet connected with the water outlet of boiler heating system.
