Description

Foam maker
Technical field
The utility model relates to a kind of cleaner, particularly a kind of foam maker that is used for carrying out in narrow and small places, space such as down-hole mining working faces the foam dust-removing equipment of dust hazard management.
Background technology
In progress of coal mining, can produce a large amount of dust, and the coal digging operation is the master operation of producing dirt, its dust-producing amount accounts for more than 80% of total dust, the physical and mental health of serious harm coal miner.Present about 250,000 people of pneumoconiosis patient of China's coal-mine industry, and, have every year 3000 people to die from pneumoconiosis approximately with annual 5000 people's speed increase, brought great misery for patient and family thereof.In order to prevent and treat dust, all can adopt a series of measures in the work progress of colliery, as the water filling of spray for dust suppression machine-made egg-shaped or honey-comb coal briquets layer etc., to reduce dust pollution.
Foam dust-removing technology is the emerging in recent years a kind of dedusting technology that grows up, and it has the advantages that water consumption is few, efficiency of dust collection is high, especially respirable dust is had significant effect.Find that the core of foam dust-removing technology is frothing percentage and foaming quality in the research of foam dust-removing is used, foam maker produces foam, make the foam of generation form a closely knit solid, surround dust within the specific limits, make it, reach the purpose of depositing dust not to external diffusion.Therefore, if breaking easily, bubble amt deficiency that produces or foam all can influence the effect of dedusting.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, simple in structure, foam maker that foaming effect is good.
To achieve these goals, the utility model is taked following technical solution:
Foam maker comprises the foam maker cylindrical shell, is arranged at the air inlet pipe of foam maker barrel front end, and air inlet pipe and air compressor link; Be arranged at the Venturi tube in the foam maker cylindrical shell, Venturi tube throat leading portion tube wall is provided with charging hole; Be arranged at the feed pipe on the foam maker cylindrical shell barrel; Be arranged at the impeller support at foam maker cylindrical shell inner venturi tube rear, on the impeller support impeller be installed; Be arranged at the mixer at foam maker cylindrical shell internal lobe wheel support rear, be filled with irregular column medium in the mixer; Be arranged at the outlet of foam maker cylinder back-end.
Preferably, described charging hole is the through hole that is arranged at intervals on the Venturi tube tube wall.
Preferably, described feed pipe and described Venturi tube link, and the outlet of described feed pipe is described charging hole.
Because the addition of the relative gas of addition of foaming agent solution is less, the utility model is arranged on air inlet pipe the front end of foam maker cylindrical shell, feed pipe is arranged on the barrel at foam maker cylindrical shell front portion or middle part, Venturi tube throat leading portion tube wall is provided with charging hole, the gases at high pressure air inflow is big, gas can spray in the foaming agent solution at a high speed and mix foaming with foaming agent solution in Venturi tube, at the Venturi tube rear impeller is set, make foam more even, foam by the mixer at impeller rear, further mixes gas and foam again.The utlity model has simple in structure, reasonable in design, the characteristics that foaming effect is good.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is the structural representation of another embodiment of the utility model.
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is done explanation in further detail.
The specific embodiment
As shown in Figure 1, foam maker of the present utility model comprises foam maker cylindrical shell 1, air inlet pipe 2, Venturi tube 3, feed pipe 4, impeller 5, impeller support 6, mixer 7 and outlet 8.For convenience of description, the arrival end of air inlet pipe 2 is defined as before.
Air inlet pipe 2 is arranged at the front end of foam maker cylindrical shell 1, air inlet pipe 2 links with the air outside compressor, pressure-air enters the foam maker cylindrical shell 1 from air inlet pipe 2, air inlet pipe 2 ports of export are provided with Venturi tube 3 in the foam maker cylindrical shell 1, and gases at high pressure directly enter in the Venturi tube 3 after entering in the foam maker cylindrical shell 1.Foam maker cylindrical shell 1 barrel is provided with feed pipe 4, and feed pipe 4 and outside blowing agent holding vessel UNICOM, feed pipe 4 are positioned near the position of front portion, Venturi tube 3 throats of foam maker cylindrical shell 1, and foaming agent solution enters the foam maker cylindrical shell 1 from feed pipe 4.The tube wall of Venturi tube 3 throat's leading portions is provided with charging hole a, and the foaming agent solution that enters in the foam maker cylindrical shell 1 enters the Venturi tube 3 from charging hole a, with the gases at high pressure mixed foaming.Be provided with impeller support 6 at foam maker cylindrical shell 1 inner venturi tube 3 rears, impeller 5 is installed on the impeller support 6, impeller 5 rotates under the fluid force of gas-liquid flow promotes, and can increase the stability of foam, makes foam fine and smooth more, even.Impeller 5 rears are provided with mixer 7 in foam maker cylindrical shell 1, be filled with irregular column medium in the mixer 7, when mix slurry is passed through mixer 7, velocity of liquid assets has on the one hand slowed down, prolong mix slurry than the currency in the short distance, blowing agent can be mixed, adopted the foaming section of filling irregular column medium on the other hand, can increase the foam wall thickness, the ability that makes foam have better stability and bear pressure.Be provided with outlet 8 in foam maker cylindrical shell 1 rear end, outlet 8 links with the foam jet pipe, and foam outwards sprays through the foam jet pipe.
The course of work of the present utility model is as follows:
