The technical issues of urgent need to resolve.
Summary of the invention
In view of this, can not only guarantee to press slag effect, reduce pressure the purpose of the present invention is to provide a kind of pressure slag equipment
Slag cost, but also can be improved production efficiency, personnel labor intensity is reduced, to be further ensured that going on smoothly for production.
Another object of the present invention, which also resides in, provides a kind of pressure slag method.
To achieve the above object, the invention provides the following technical scheme:
A kind of pressure slag equipment, including the slag ladle for holding slag, and the injection dress for spraying water into the slag ladle
It sets.
Preferably, the injection apparatus includes the water pipe for being connected with water source, and the valve for controlling the water flow
Door.
Preferably, flowmeter is provided in the valve, and the flowmeter is set as water flow≤40L/min, water spray
Penetrate the time≤30min.
It preferably, further include the electromagnetic switch valve being set in the water pipe.
It preferably, further include the controller opened and closed for controlling the electromagnetic switch valve.
Preferably, the electromagnetic switch valve is multiple, and multiple electromagnetic switch valves are connected in series.
A kind of pressure slag method, comprising:
1) slag is placed in slag ladle；
2) water injection is carried out to the slag.
Preferably, discontinuity injection is carried out to the slag.
As can be seen from the above technical solutions, pressure slag equipment disclosed in this invention, including the slag ladle for holding slag,
With the injection apparatus for spraying water into slag ladle.When carrying out slag pressure slag, slag is put into slag ladle first, starting injection
Device carries out water injection to slag, so that slag is carried out pressure Slag treatment.Carrying out pressure Slag treatment using the device can not only protect
Card pressure slag effect, reduces pressure slag cost, but also can be improved production efficiency, personnel labor intensity is reduced, to further protect
Card production is gone on smoothly.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, below to embodiment or existing
Attached drawing needed in technical description is briefly described, it is clear that, the accompanying drawings in the following description is only this hair
Bright embodiment for those of ordinary skill in the art without creative efforts, can also be according to mentioning
The attached drawing of confession obtains other attached drawings.
Fig. 1 is the structural schematic diagram of the pressure slag equipment disclosed in the embodiment of the present invention.
Wherein, the title of each component is as follows:
1- slag ladle, 2- injection apparatus, 21- water pipe, 22- valve, 23- electromagnetic switch valve.
Specific embodiment
In view of this, core of the invention is to provide a kind of pressure slag equipment, it can not only guarantee to press slag effect, reduce pressure
Slag cost, but also can be improved production efficiency, personnel labor intensity is reduced, to be further ensured that going on smoothly for production.
Another core of the invention, which also resides in, provides a kind of pressure slag method.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
Pressure slag equipment disclosed in the embodiment of the present invention, including the slag ladle 1 for holding slag, and for into slag ladle 1
Spray the injection apparatus 2 of water.When carrying out slag pressure slag, slag is put into slag ladle 1 first, starts injection apparatus 2 to slag
Water injection is carried out, so that slag is carried out pressure Slag treatment.Carrying out pressure Slag treatment using the device can not only guarantee to press slag effect,
Pressure slag cost is reduced, but also can be improved production efficiency, personnel labor intensity is reduced, to be further ensured that the smooth of production
It carries out.
As shown in Figure 1, injection apparatus disclosed in the embodiment of the present invention, including the water pipe 21 for being connected with water source, and
For controlling the valve 22 of water flow.Water flows to slag ladle 1 from water pipe 21 by valve 22, sprays the slag in slag ladle 1,
Slag is subjected to pressure Slag treatment.
It should be noted that being provided with flowmeter in valve 22, and the specific setting of flowmeter is preferably arranged to water flow
