Description

Rotary drill dedusting water supply installation
Technical field
Cleaner is the utility model is related to, in particular to a kind of rotary drill dedusting water supply installation.
Background technology
Rotary drill is a kind of efficiently mining perforating apparatus, it by the revolution of drill bit and under be pressed in ground and form blasthole, Pressing mechanism and slew gear cause rock bit to turn round while being drilled down under fluid motor-driven in the course of work. In order to which the slag formed in drilling process is discharged, the compressed air of Wind Volume can be passed through on the top of drilling rod, compressed air is led to Cross drilling rod central ventilation pipe to spray through the exhaust vent at drill bit, by outside the slag blowout blasthole at blasthole bottom.Meanwhile in order to prevent by The slag blown out outside blasthole produces dust, is adding water, water and compression in the compressed air for entering drilling rod central ventilation pipe toward meeting The exhaust vent that the air-water mixture that air is formed is sent at drill bit moistens slag, and now slag is blown after blasthole mouth just not Easily kick up a dust, play depositing dust dustproof function.At present, the operation for water being mixed into compressed air is to utilize rotary drill dust-proof water tank In water be evacuated to by immersible pump in the rig air main being connected with drilling rod central ventilation pipe inlet end, in rig air main The air-water mixture that water and compressed gas are mixed to form delivers to exhaust vent through drilling rod central ventilation pipe, and then by the slag at blasthole bottom Moistening.But this dedusting structure has the following disadvantages:1) in the course of work, because of immersible pump pressure of supply water deficiency and by rig The tangential force of the swiftly flowing gas of air main influences, and it is difficult the phenomenon being mixed into rig air main to occur water often;2) dive under water Pump is often arranged in dust-proof water tank, needs first to bleed off the water in water tank once immersible pump or fluid level controller break down, And people will crawl into narrow space and could be repaired, not only waste water resource, and repairing also extremely difficult.
The content of the invention
The purpose of this utility model seeks to provide a kind of rotary drill dedusting water supply installation, and the device can be realized smoothly Mixing wastewater with air, and significantly reduce maintenance difficulties and equipment cost.
To achieve the above object, the technical solution adopted in the utility model is:A kind of rotary drill dedusting water supply installation, Including rig air main and dust-proof water tank, it is connected between the rig air main and dust-proof water tank by connecting water pipe, it is described Venturi tube is provided with rig air main, the arrival end of the Venturi tube is connected with compressed air inlet pipe, the text The diffusing opening of venturi is connected with the entrance of the rig air main, and the throat of the Venturi tube offers throat's water inlet Mouthful, the connecting water pipe water outlet end is connected with throat's water inlet.
The utility model is connected Venturi tube (jet pipe) on rig air main, utilizes high pressure caused by air compressor Water in dust-proof water tank is sucked the mixed liquid room of Venturi tube with boring by Wind Volume gas in absorption affinity caused by venturi throat The bottom hole moistening slag being sent into after gas mixing atomization in owner's airduct at drill bit of drilling machine, and then play depositing dust and dedusting work With;The utility model eliminates immersible pump and the safety valve supporting with it, the accessory such as check valve and fluid level controller, so as to save The manufacturing cost of rig;In addition, Venturi tube of the present utility model is with little need for maintenance, the operating cost of rig It can substantially reduce.
Further, the second compressed air inlet pipe, second compressed air inlet pipe are connected with the connecting water pipe It is provided with and blows water one-way valve.Blow water one-way valve and the water remained in pipe-line system is removed in winter per tour operation after-blow, prevent pipeline quilt Freeze.
Further, it is provided with heater in the dust-proof water tank.Heater is used to the water in dust-proof water tank add in the winter time Heat avoids the water freezing in dust-proof water tank.
Further, the connecting water pipe is provided with runoff investigation mechanism.
Brief description of the drawings
Fig. 1 is a kind of structural representation of rotary drill dedusting water supply installation.
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings, is easy to more clearly understand that this practicality is new Type, but they do not form to the utility model and limited.
Rotary drill as shown in Figure 1 dedusting water supply installation, including rig air main 1 and dust-proof water tank 2, the main wind of rig It is connected between pipe 1 and dust-proof water tank 2 by connecting water pipe 3, Venturi tube 4, Venturi tube 4 is provided with rig air main 1 Arrival end be connected with compressed air inlet pipe 5, air compressor 6 is connected with compressed air inlet pipe 5, Venturi tube 4 Diffusing opening is connected with the entrance of rig air main 1, and the throat of Venturi tube 4 offers throat's water inlet 11, and connecting water pipe 3 goes out Mouth of a river end is connected with throat water inlet 11.Connecting water pipe 3 is provided with runoff investigation mechanism 10, and the runoff investigation mechanism 10 can use Flowmeter;The second compressed air inlet pipe 7 for blowing water is also connected with connecting water pipe 3, is set on the second compressed air inlet pipe 7 Have and blow water one-way valve 8, this blows water one-way valve 8 and the water remained in pipe-line system is removed in winter per tour operation after-blow, prevents pipeline quilt Freeze.Heater 9 is additionally provided with dust-proof water tank 2, for being avoided in the winter time to the water heating in dust-proof water tank 2 in dust-proof water tank Water freezing.
Above-mentioned rotary drill is as follows with the course of work of dedusting water supply installation:Wind Volume caused by air compressor 6 compresses The entrance of gas flow through venturi 4 successively, after contraction section and throat, sprayed from diffuser, because the contraction section of Venturi tube 4 circulates The reduction of sectional area, gas flow rate are increased sharply, and certain vacuum is produced at throat's water inlet 11, and then form absorption affinity, are removed Water in dirt water tank 2 because swiftly flowing gas is in absorption affinity caused by its throat in Venturi tube 4 and " being swept along " entrance The mixed liquid room of throat, realizes mixing wastewater with air, and then air-water mixture is ejected into the rear end of rig air main 1 through diffuser again, most Enter aperture bottom hole at drill bit along drilling rod center eventually, and then moisten slag depositing dust dedusting purpose.
