In order to realize the purpose of this utility model, intend using following technology：
A kind of water-glass sand snap frozen demoulding regenerating tank, it is characterised in that tank body is externally provided with what is be connected with refrigerating plant
Chuck, the tank body top are provided with spray pipeline and the exhaust pipeline being connected with air-introduced machine, and side-walls are provided with sand inlet, and bottom is set
There are sand export and the air blast pipeline provided with air blower, inside is provided with the agitator driven by motor.
Further, the sand inlet is disposed in proximity to the side-walls at the top of the tank body, and the spray pipeline end is located at
Spray nozzle in the tank body is arranged above the sand inlet.
Further, the air blast pipeline is connected with the refrigerating plant.
Further, the refrigerating plant uses refrigerator.
Further, the air blast line end is provided with check valve.
Further, the agitator uses plate and frame paddle.
The beneficial effects of the utility model are：
1st, the utility model makes used sodium silicate sand surface form solution integument to bonding by the spray structure in tank body
Agent film is swelled, and makes solution layer freezing that stereomutation occur by refrigerating plant, to utilize stress caused by stereomutation,
Adhensive membrane is formed crackle, and then demoulding is realized by mechanical agitation.The utility model demoulding efficiency is high, demoulding effect is good.
2nd, the utility model is introduced air-flow in tank body from old sand material bottom by air blower, is blown up, cooperation is stirred
Mix device to stir old sand, the adhensive membrane for making to come off is discharged with air-flow from exhaust pipeline, thus the utility model is arranged without sewage
Put.
Brief description of the drawings
Fig. 1 shows the utility model structure diagram.
Embodiment
As shown in figure 1, a kind of water-glass sand snap frozen demoulding regenerating tank, tank body 1 is externally provided with to be connected with refrigerating plant 10
Chuck 2, the top of the tank body 1 is provided with spray pipeline 3 and the exhaust pipeline 4 being connected with air-introduced machine 20, and side-walls are provided with into sand
Mouth 5, bottom are provided with sand export 6 and the air blast pipeline 7 provided with air blower 30, and inside is provided with the agitator driven by motor 40
8.The refrigerating plant 10 uses refrigerator, thinks the transporting low temperature refrigerant of chuck 2, makes environment temperature in the tank body 1
Degree is less than 0 DEG C.The sand inlet 5 is used to be sent into used sodium silicate sand into the tank body 1.The spray pipeline 3 is used for described
Conveying demoulding solution in tank body 1.The sand inlet 5 is disposed in proximity to the side-walls at the top of tank body 1, the spray pipeline 3
The spray nozzle 31 that end is located in the tank body 1 is arranged at the top of sand inlet 5.Used sodium silicate sand is from the sand inlet 5
After place enters the tank body 1, i.e., contacted with the demoulding solution at the spray pipeline 3.The spray nozzle 31 is carried out to solution
After atomization, be advantageous to increase the contact area of old sand and demoulding solution, reduce demoulding solution usage amount.The sand export 6 is used for
Used sodium silicate sand completes the blanking after regeneration.The agitator 8 and the motor 40 use existing agitating device scheme, institute
State agitator 8 and mechanical agitation is carried out to used sodium silicate sand, make between used sodium silicate sand, used sodium silicate sand and the inwall of tank body 1, with
And used sodium silicate sand collides with the agitator 8, rubbing action, the adhensive membrane of used sodium silicate sand outer layer is set to occur to take off
Fall.The air blower 30 blows outer gas stream from the tank body 1 is bottom up, and the air-introduced machine 20 coordinates the air blower
30, it will draw on air-flow, discharged from the exhaust pipeline 4, you can used sodium silicate sand and adhensive membrane are sieved using current rate, will
Adhensive membrane after coming off is blown afloat from the bottom of tank body 1, is discharged from top.
The air blast pipeline 7 is connected with the refrigerating plant 10.Ensure in outer gas stream temperature and the tank body 1 of introducing
Environment is adapted, and to avoid the nilas that demoulding solution is formed outside used sodium silicate sand from dissolving, influences demoulding effect.
