Abstract
An automatic foaming agent adding device mainly comprises a filter, a main pipe, a jet device, a side branch pipe, a stop valve, a check valve, a needle valve, a hose joint and a liquid sucking hose. One end of an inlet joint of the main pipe is connected with an underground water pipe, and one end of an outlet joint of the main pipe is connected with a foam maker. When water in a pipeline flows through the adding device, foaming agent is automatically sucked by the aid of negative pressure formed by the jet device, and the foaming agent and the water are mixed to form uniform foaming liquor to flow out of the adding device. Vacuum degree of a cavity of the jet device and back pressure of an outlet end can be simultaneously adjusted by means of adjusting the check valve of a side branch, the foaming agent can be continuously and stably sucked, finally, adding quantity of the foaming agent can be finely adjusted by the aid of the needle valve, and high-precision adjustment of adding of the foaming agent is realized. The automatic foaming agent adding device is simple in structure, small in volume, light in weight, high in adjustment precision and convenient in operation, is intrinsically safe and is particularly suitable for small-scale mixing of the foaming agent and water in narrow and small underground spaces and locations of coal mines.
Description
Technical field
The utility model relates to the automatic adding set of a kind of blowing agent, and blowing agent mixes with the reasonable of press water when being particularly useful for that small space carries out the foam depositing dust under coal mine.
Background technology
In order to prevent and treat dust, generally adopt dust preventions such as atomizing de-dusting and coal-bed flooding under the coal mine, but all can not contain the dust disaster well because efficiency of dust collection is lower.The foam dust-settling technology has remarkable advantages such as efficient height, water consumption be little; Since proposing the 1950's; Obtained bigger development, at home and abroad some mining areas have obtained test application, but the blowing agent corollary apparatus complex structure in the foam dust-settling technology, floor space big, regulate inconvenience, the addition ratio is difficult to control; Cause the too high and waste of material of cost, greatly restricted the development and the application of foam dust-settling technology.Experiment showed, in a large number that according to the laboratory ratio of blowing agent is at 0.6%～1% o'clock, the depositing dust of foam and economic resultant effect are best.The blender that is used for other technical field at present has multiple, is 200810090941.3 to disclose a kind of adjustment type blender like: the patent No..Dislocation generation different opening takes place through the corresponding hole of adjustable ring and orifice plate and carries out mixing of different proportion in this blender, but this blender water and blowing agent all need injected by external pressure.The patent No. is that 200420016278.X discloses a kind of combined type venturi fertilising valve, adopts water flow control valve to realize mixing with the parallel connection of venturi control valve, and this device Venturi tube structure is simple, but its negative pressure is less, and system is unstable.The patent No. is 200620078397.7 to disclose a kind of blender of big flow, and this blender comprises and draw bubble pipe, aqueduct, induction tunnel, draws on the bubble pipe to be disposed with Foam switch valve and flow control valve, and aqueduct is provided with water valve.Wherein flow control valve comprises push pedal, annular dividing plate, conical foam awl, connecting rod and back-moving spring.But its foams mix ratio is self-regulating through back-moving spring, so mixed effect is poor, and proportioning can't reach depositing dust foam The Best Mixed ratio scope.
