Abstract
The utility model relates to an air purifying device for underground construction engineering, which is used for the underground construction engineering or tunnel engineering work environments and has the functions of ventilation, dust removal and air sterilization. The utility model is composed of a trolley, a truss placed on the trolley, a wind cylinder arranged on the truss, a water jet injector arranged in the wind cylinder, a water tank arranged in the trolley, a water pump which is respectively connected with the water tank and the water jet injector by pipelines, and an electric control box for controlling the water pump. The end part of the water jet injector in the wind cylinder is additionally provided with a fan controlled by the electric control box and connected by a circuit. The utility model has the advantages of high wind pressure, fast wind speed, good effects of ventilation, dust removal and poison removal, etc.
Description
The utility model is a kind of cleaning equipment, in underground engineering or Tunnel Engineering operating environment, plays ventilation, dedusting and air disinfection function.
Existing underground engineering air cleaning unit, owing to structural reason, the formed negative pressure of water jet high velocity jet is difficult to guarantee that the water flow in air duct has enough blast and wind speed, so the large quantity of exhaust gas that a large amount of dust and the trackless Transport Machinery of underground engineering generation are discharged can not purify effectively, influences the healthy of operating personnel.
Task of the present utility model is will provide a kind of to make water jet in the air duct have that blast is big, wind speed fast, dust removal by ventilation removes the effective underground engineering air cleaner of poison.
Task of the present utility model is finished like this, a kind of underground engineering air cleaner, by dolly 6, place the truss 8 on the dolly 6, be located at air duct 4 on the truss 8, respectively be located at the water jet injector 10 in the air duct 4 and be located at the water tank 3 of dolly 6 the insides, the water pump 5 that is connected with water tank 3 and water jet injector 10 respectively by pipeline, the electric cabinet 7 of control water pump 5 work form, now done improvement, the blower fan 11 that is subjected to electric cabinet 7 controls by the circuit connection has been set up in the end of the water jet injector 10 in air duct 4.
The utility model is owing to done above-mentioned improvement, thereby guaranteed that it is same direction that water jet and blower fan are pressed into gas, thereby the blast that the formed negative pressure of water jet high velocity jet and blower fan are produced is superposeed effectively, thereby the interior water flow of air duct that has guaranteed this device has enough blast and wind speed, played the effect that a large amount of dust that underground engineering is produced and Work machine institute exhaust gas discharged purify effectively, improved the underground engineering operating environment, ensured that the operating personnel's is healthy.
Below in conjunction with accompanying drawing the utility model is further described below.
Accompanying drawing is the utility model structure chart.
Is furnished with the malicious additive of removing in the clear water in the water tank 3 of the present utility model.Water tank 3 is fixed on an end of dolly 6, and its bottom is porose, and port lid is arranged on the hole, opens port lid and just water in the water tank 3 and the dust that is deposited in the water tank 3 can be got rid of.Two one end side portion of water tank 3 are not provided with water-in and water-out joint 13,14, water supply connector 13 is connected with the water source by pipeline, water out adapter 14 is connected with an end of flexible pipe 16, the other end of flexible pipe 16 is connected with the water inlet of the water pump 5 that is located at the dolly 6 interior other ends, the delivery port of water pump 5 is connected with an end of flexible pipe 9, and the other end of flexible pipe 9 is connected with water jet injector 10.Water pump 5 is by motor 17 drive work, and motor 17 is by electric cabinet 7 controls.Also be connected with flexible pipe 18 between water tank 3 and water pump 5, it act as overflow, in case promptly the pressure of water pump 5 is excessive, then by 18 overflows of this flexible pipe to give decompression.
Dolly 6 is welded by angle bar, and solid welding support 15 on the skeleton of dolly 6 by with two ends of truss 8 and being connected of support 15, is arranged at truss 8 on the dolly 6 thereby can reach, and keeps certain parallel distance with dolly 6.Air duct 4 is horizontally-arranged on the truss 8, and the one end is connected with the middle part of backwater tube 2, and two ends of backwater tube 2 are connected with water tank 3 with return air tube 1 respectively, and the other end of air duct 4 is connected with dust hood 12.It is interior apart from dust hood 12 a distance that water jet injector 10, blower fan 11 are successively set on air duct 4, and the forced axial flow blower of blower fan 11 employings is connected with electric cabinet 7 by circuit, by electric cabinet 7 its work of control.
When using the utility model, as long as open the switch of electric cabinet 7, motor 17 drives water pump 5 work, meanwhile blower fan 11 is also worked, blower fan 11 is pressed into air duct 4 with extraneous air from dust hood 12, water pump 5 is gone into water jet injector 10 to the hydraulic pressure that removes malicious additive that contains in the water tank 3 by flexible pipe 16, thereby by water jet injector 10 ejection at a high speed, because the air-flow that is pressed into of water jet injection direction and blower fan is same direction, the blast that formed negative pressure of water jet high velocity jet and blower fan 11 are produced is superimposed, make the water flow in the air duct 4 have bigger blast and wind speed, thereby the air inducing that has increased 12 pairs of surrounding environment of dust hood effectively capture radius.Toxic dusty gas in dust hood 12 suction air ducts 4 is through water jet vaporific spray at a high speed, the dust quilt is adsorbing and trapping effectively, toxic gas neutralizes with removing malicious additive reaction, air water is separated at the air duct afterbody, pure air is discharged from return air tube 1, and the dust-laden scavenging solution flows into water tank 3 from backwater tube 2, and grit precipitates in water tank 3, liquid is recycled continuously, thereby plays the catharsis to the air of underground engineer operation environment effectively.
