Abstract
The utility model discloses a ring pump type negative pressure proportioning mixer and belongs to coal mine foam fire-extinguishing devices. The mixer is formed by assembling a water inlet filtering net head, a ring pump clip, a medicine inhalation tube, a conical guide tube and a medicine-water mixing tube, wherein the medicine inhalation tube is arranged on the medicine-water mixing tube and is inclined to the lateral direction of the water inlet end; an inclined angle between an axis of the medicine inhalation tube and an axis of the medicine-water mixing tube is 45 degrees; the inner diameters of the medicine inhalation tube and the medicine-water mixing tube are respectively 12mm and 40mm. When the mixer is operated, a proportion of the medicine and water is reasonable, the generated fire-extinguishing foam is high in quality, the fire-extinguishing efficiency is high, and the power consumption during fire-extinguishing operation is low.
Description
Technical field
The utility model belongs to colliery fixed froth installation, relates generally to a kind of medicine and water mixer that produces fire foam.
Background technology
Medicine and water mixer are a kind of devices that medicine and water mixing is produced to fire extinguishing foams that is fitted on water pump, and the foams of generation are ejected in colliery the operation of putting out a fire of ignition point place through water pump, Flexible water pipe.On existing Ring-pumping Negative Pressure blender, it is equipped that medicine absorbing tube and liquid medicine mixing tube are vertical angle, operation consumption of power is large, and medicine absorbing tube internal diameter and the supporting not science of liquid medicine mixing tube bore size, dose and the water yield ratio in pipe of entering is unreasonable, operation Chinese medicine and water mixing quality are poor, and the fire extinguishing of generation is difficult for guaranteeing with foam quality, has affected coal mine fire fighting operating efficiency and fire extinguishing effect.
Summary of the invention
The purpose of this utility model is exactly the problem existing for above-mentioned prior art, and research provides a kind of Ring-pumping Negative Pressure proportioner, reaches the object that increases substantially fire foam quality and fire-fighting efficiency, reduces power consumption.
Basic Design of the present utility model is, at the equipped conical flow guiding pipe in liquid medicine mixing tube water inlet end inner side, on the water inlet end of liquid medicine mixing tube and water outlet end, be installed into respectively water screen head and ring pump clamp, on liquid medicine mixing tube sidewall, medicine absorbing tube is installed, described medicine absorbing tube is to water inlet end side direction on liquid medicine mixing tube, between its medicine absorbing tube axial line and liquid medicine mixing tube axial line, inclined angle alpha is 45 °, described medicine absorbing tube bore Φ
1be 12 millimeters, described liquid medicine mixing tube bore Φ
2be 40 millimeters, so far form Ring-pumping Negative Pressure proportioner.
The utility model on theoretical analysis foundation, through a large amount of test, scientific and reasonable definite structure technical parameter that finishes, have medicine and water ratio rationally, the fire foam quality that produces is good, fire-fighting efficiency is high, the little feature of operation power consumption of putting out a fire.
Accompanying drawing explanation
Fig. 1 is Ring-pumping Negative Pressure proportioner general structure schematic diagram;
Fig. 2 is bowing to view of Fig. 1.
Piece number explanation in figure:
1, inlet strainer head, 2, ring pump clamp, 3, medicine absorbing tube, 4, conical flow guiding pipe, 5, liquid medicine mixing tube.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model optimum implementation is described in detail.A kind of Ring-pumping Negative Pressure proportioner, at the liquid medicine mixing tube 5 equipped conical flow guiding pipes 4 in water inlet end inner side, on the water inlet end of liquid medicine mixing tube 5 and water outlet end, be installed into respectively water screen head 1 and ring pump clamp 2, on liquid medicine mixing tube 5 sidewalls, medicine absorbing tube 3 is installed, described medicine absorbing tube 3 is to water inlet end side direction on liquid medicine mixing tube 5, between its medicine absorbing tube 3 axial lines and liquid medicine mixing tube 5 axial lines, inclined angle alpha is 45 °, described medicine absorbing tube 3 bore Φ
1be 12 millimeters, described liquid medicine mixing tube 5 bore Φ
2it is 40 millimeters.
When coal mine fire fighting operation is used, utilize ring pump clamp 2 that this device is fitted on water pump, the water side of liquid medicine mixing tube 5 is communicated with pump intake, and medicine absorbing tube 3 and inlet strainer head 1 are communicated with medicine-chest and water source respectively.Under the negative-pressure sucking of water pump, water is directly to entering in liquid medicine mixing tube 5 after inlet strainer head 1, and medicine is 45 ° of inclination angles through medicine absorbing tube 3 and enters in liquid mixing tube 5, after mixing with water completed percentage, sends into fiery point, the operation of putting out a fire by water pump through water band.
