The utility model discloses well compressed air and expanding foam solution flash mixed and homodisperse form compact little foam in the expanding foam solution, the stability of improving production and the quality of panel.
Description
Technical field
The utility model relates to gypsum board production line equipment, specifically a kind of plasterboard foam device.
Background technology
Blowing agent has important effect in Thistle board is produced, and it can make product meet the weight reducing plasterboard under national regulation intensity.Current domestic gypsum board production line adopts the foaming machines such as Homogenizing pump usually, and foaming agent consumption is large, and foam is large, and production stability is poor.
Summary of the invention
For solving the technical problem of above-mentioned existence, the utility model provides a kind of plasterboard foam device, and compressed air and expanding foam solution rapid mixing are also dispersed in expanding foam solution, form fine and close little foam, improves the quality of stability and the sheet material produced.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of plasterboard foam device, include expanding foam solution conveying device, compressed air conveying pipeline, centrifugal pump A and centrifugal pump B, described expanding foam solution conveying device is by the inlet communication of pipeline and centrifugal pump A, expanding foam solution is delivered in centrifugal pump A, described compressed air conveying pipeline is connected with the transfer pipeline of expanding foam solution, the import of centrifugal pump A is entered after being mixed with expanding foam solution by compressed air, the outlet of described centrifugal pump A is by the outlet of pipeline and centrifugal pump B, and the mixing material after foaming terminates is discharged by the import of centrifugal pump B.
The transfer pipeline of described expanding foam solution conveying device is provided with expanding foam solution flowmeter, described compressed air conveying pipeline is provided with Pressure gauge A, mass air flow sensor and ball valve, the connecting line between described centrifugal pump A and centrifugal pump B is provided with Pressure gauge B.
The utility model devises two centrifugal pumps, centrifugal pump A is entered in a usual manner after expanding foam solution mixes with compressed air, gas-liquid two-phase particle receives the stronger shearing of impeller and percussion, be dispersed into tiny dispersion, achieve the rapid mixing of gas-liquid, centrifugal pump B is entered afterwards in unconventional mode, namely enter in cavity by the outlet of centrifugal pump B, very strong pressure is formed in cavity, mixed liquor is mixed further and plays the effect of " mill bubble ", blowing agent is made to form fine and close tiny foam, more even, be added into plasterboard internal stability better, improve the board quality of finished product, decrease the consumption of blowing agent, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1, this plasterboard foam device, include expanding foam solution conveying device 1, compressed air conveying pipeline 9, centrifugal pump A6 and centrifugal pump B8, described expanding foam solution conveying device 1 is by the inlet communication of pipeline and centrifugal pump A6, expanding foam solution is delivered in centrifugal pump A6, described compressed air conveying pipeline 9 is connected with the transfer pipeline of expanding foam solution, the import of centrifugal pump A6 is entered after being mixed with expanding foam solution by compressed air, the outlet of described centrifugal pump A6 is by the outlet of pipeline and centrifugal pump B7, and the mixing material after foaming terminates is discharged by the import of centrifugal pump B8.
Described expanding foam solution conveying device 1 adopts screw pump, its transfer pipeline is provided with expanding foam solution flowmeter 2, described compressed air conveying pipeline 9 is provided with Pressure gauge A5, mass air flow sensor 4 and ball valve 3, the connecting line between described centrifugal pump A6 and centrifugal pump B8 is provided with Pressure gauge B7.
Expanding foam solution is transported to pipeline by expanding foam solution conveying device 1, and blowing agent flowmeter 2 plays observation effect; Compressed air squeezes into the transfer pipeline of expanding foam solution from compressed air conveying pipeline 9, and mass air flow sensor 4 conveniently observes air mass flow, and ball valve 3 controls suitable air inflow.Be mixed with this expanding foam solution and compressed-air actuated liquid first through the import of centrifugal pump A6, then export out the outlet entering centrifugal pump B8 afterwards from centrifugal pump A6, finally get from the import of centrifugal pump B8, that is mixing material in a usual manner from centrifugal pump A6 out after with the outlet of unconventional mode through centrifugal pump B8, then discharge from the import of centrifugal pump B8.
When the impeller High Rotation Speed of centrifugal pump A6, drive blowing agent and compressed air mixed solution in cavity to rotate thereupon, form the circulation of a rolling, and produce a very large vortex.At this moment, be positioned at the gas-liquid two-phase particle of foaming agent solution top gas-liquid interface, will accompany and under, drop to the bottom of vortex in rapid spiral shape, at vane edge 2.5 ~ 5 ㎝ place, form a turbulent area.In this region, gas-liquid two-phase particle is subject to the stronger shearing of impeller and percussion, be dispersed into tiny dispersion, achieve the mixing of gas-liquid soon, gas uniform is made to be scattered in liquid, achieve the introducing of gas, centrifugal pump B8 is owing to entering, the artificial anti-dress of outlet, mixed liquor is hindered to discharge smoothly, very strong pressure is formed in cavity, mixed liquor is mixed further, and play the effect that " mill bubble " forms fine and close vesicle, the foaming agent foam of discharging from centrifugal pump B8 import is effective, foam is little, stability is high, the corresponding minimizing of foaming dosage consumed, reduce production cost.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
