Specific embodiment
As shown in Figure 1 and Figure 2, dry method pressure break of the present invention sand grains cools down the ontology 6 that holding vessel includes rounded tank body, fortune
When defeated, for ease of transport, which is laid-flat status, in use, 6 right end of ontology is lifted, the sand grains in tank body, which glides, to be arranged
Go out.Supplied gas and sand grains while the sand inlet 1 entered, 1 external CO of sand inlet are provided on ontology 62Compressor, on ontology 6 also
It is provided with the sand grains dump valve 7 of external Venturi tube 8.Preferably, it is installed with CO between sand grains dump valve 7 and Venturi tube 82Increase
Press pump.Ontology 6 is installed on bottom sled 9, and left end bottom is rotatablely connected by fixed hinge 10 and bottom sled 9, in this way, ontology 6 is right
End can be lifted away from bottom sled 9 under external force.Preferably, a pair of of lifting lug 3 of 6 right end front and rear sides of ontology setting, when use, are first used
Crane, which hangs lifting lug 3, makes ontology 6 be rotated around fixed hinge 10, lifts its right end.6 right end bottom of ontology passes through hinges 11
The left end of connection support bar 13, when the right end of ontology 6 is lifted, the right end of supporting rod 13 naturally droop under the effect of gravity and with
Hold-down support 12 on bottom sled 9 is connected, and effective support is played when Tank tilting is placed.
The sand grains cooling means of holding vessel is cooled down with sand grains using above-mentioned dry method pressure break, is included the following steps：
When A, working, ontology 6 is kept flat, passes through CO2Compressor is by gaseous state CO2This is sent by sand inlet 1 together together with sand grains
In body 6；
B, by CO2Compressor is by the gaseous state CO in tank2The gas discharge outlet 2 set from ontology 6 is extracted out, such tape loop
Sand enters in ontology 6, until tank is full；Due to being gaseous state CO2Band sand enters tank, therefore sand grains just obtains during tank is entered
Cooling will not make the liquid CO in tank body when subsequently using2Heating vaporization meets construction needs.
C、CO2When dry method pressing crack construction operation needs sand grains, 6 one end of ontology, which is lifted, makes its slant setting, opens sand grains
Dump valve 7, by CO2Booster pump supplies and passes through the liquid CO of Venturi tube 82Sand grains can be taken in subsequent mixing apparatus, band
The size of sand amount can be controlled with sand grains dump valve 7.
In addition, being checked for ease of entering in tank, it is provided on ontology 6 into manhole 4.Safety valve is provided on ontology 6
Installing port 5 can install safety valve to ensure superpressure safety dumping.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
It encloses and is defined, under the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art are to the technical side of the present invention
