Description

A kind of jet absorption type sprayer unit

Technical field

Mine atomizing de-dusting technical field is the utility model is related to, is more particularly to a kind of jet absorption type sprayer unit.

Background technology

In coal mine underground construction, mine dust endangers downhole production, pollutes underground work situation, and endanger The health of worker.With the continuous lifting of coal production Mechanization Level, the yield of dust is consequently increased, dust danger Evil degree is increasing；And with the continuous improvement of coal mine fully-mechanized mining mechanization degree and the continuous maturation of fully mechanized mining, work Make that the speed of face back production is more and more faster, the aerial density more and more higher of the dust in mining roadway certainly will be caused, especially Rock gangway and coal road.At present, mine underground dustproof class product is essentially all and uses directly to be atomized water route extraction with fog-spray nozzle Depositing dust, such a mode has three drawbacks, first, dust removing effects are bad, shower nozzle atomizing effect has much relations, mine water with hydraulic pressure Pressure generally in 2.5~4Mpa or so, according to actual use situation, more than 6Mpa hydraulic pressure, directly uses shower nozzle atomized dust settling, removed Dirt effect could be applicable reluctantly；Second, water consumption is big, directly sprayed using shower nozzle, water-mist conversion ratio is not high, substantial amounts of water resource It can not be atomized, directly be lost in, cause Floor Heave in Roadway, ponding, add the workload and renovating environment workload of draining；Third, Traditional spraying diversion without filter, time length to causing shower nozzle to block among shower nozzle.

Utility model content

Technical problem to be solved in the utility model is the provision of a kind of nebulization efficiency height, spraying apart from remote, depositing dust Area is big, the jet absorption type sprayer unit of cost savings.

The utility model is that solve above-mentioned technical problem by the following technical programs：

Embodiment

Embodiment of the present utility model is elaborated below, the present embodiment using technical solutions of the utility model before Put and implemented, give detailed embodiment and specific operating process, but the scope of protection of the utility model is unlimited In following embodiments.

As shown in figure 1, a kind of jet absorption type sprayer unit, including blast pipe 1, water inlet pipe 2, body spray 3 and injection spray pipe 4, spray Mist body 3 is " work " type structure, including the wind passage 31 and aquaporin 32 that back segment is connected by interface channel 33, wind passage 31 and water Passage 32 be arranged in parallel, and wind passage 31 and aquaporin 32 are 1.5 cun welded tubes of the length for 250mm, and the two back segment passes through 25mm Welded tube is welded as interface channel 33 and connected；Blast pipe 1 is 16mm flexible pipes, and one end is connected with wind regime equipment (not shown), another End connects with the front end of wind passage 31, and the rear end of wind passage 31 connects with injection spray pipe 4, and injection spray pipe 4 is 16mm flexible pipes, and can root Pipe range is adjusted according to use demand；Water inlet pipe 2 is 10mm flexible pipes, and one end is connected with water source equipment (not shown), and the other end leads to water The front end connection in road 32, the back-end sealing of aquaporin 32.

It is respectively that body spray 3 is supplied by blast pipe 1 and water inlet pipe 2 in use, first opening wind regime equipment and water source equipment Wind and water, its apoplexy enters wind passage 31 and fully to increase blast, water enters aquaporin 32 for circulation in it, and with having filled The high-pressure blast of circulation is divided quickly to mix, high atomisation, air intake bore is 1.6 times of water inlet bore, it is ensured that enough Blast, otherwise atomizing effect is bad, and then the water through atomization uniformly, is quickly sprayed by fog-spray nozzle, to reach dust-proof, depositing dust effect Fruit.

In addition, the first stop valve 5, first filter 6 and reflux valve 7 are disposed between blast pipe 1 and wind passage 31； The second stop valve 5 ' and the second filter 6 ' are disposed between water inlet pipe 2 and aquaporin 32.Blast pipe 1 and injection spray pipe 4 it Between be provided with two-way valve 8.First stop valve 5 serves as volume damper, and the second stop valve 5 ' serves as water regulating valve.

It is different according to the dust concentration of site environment, can be respectively by the first stop valve 5 and the second stop valve 5 ' to air quantity Suitable regulation is carried out with water, changes the size of water fog particle after atomization, so as to change the concentration of spraying, to realize spray drop The optimum efficiency of dirt.In addition the filter 6 ' of first filter 6 and second may filter that the impurity in wind and water, effectively prevent from spraying First 4 block, and extend the service life of sprayer unit.

Used as shown in Fig. 2 the sprayer unit is fixed by two U-shaped 9 rings, the U-shaped ring 9 is enclosed on body spray 3, is had Body is enclosed on 1.5 cun of welded tubes of wind passage 31, and the opening of U-shaped ring 9 is connected and is bolted by attachment spacers 10, even Connection pad piece 10 can be fixed by screws at the correct position of cloud point to be painted.

The sprayer unit may be arranged at colliery main entry, coal-face (two lanes and support move frame spraying), driving face Meet head on and each transfer point of ore deposit producing coal system.To sum up, it is as follows the advantages of jet absorption type sprayer unit of the present utility model：

(1) sprayer unit effectively solves the phenomenon that existing sprayer unit water outlet does not go out mist, strengthens and increases spray The atomizing effect of mist facility, water smoke is covered with whole space, be sufficiently humidified so as to be attached to the dust in underground air, effective control Dust concentration in underground air, improves dust-laying effect, mine dust preventing and controlling is greatly improved.And Water-mist that a small amount of water resource can be carried out to peak efficiency converts, and spraying distance is remote, and atomisation area is big, and cooling depositing dust is explosion-proof Anti-flaming effect is good, while also accomplishes water resource rationally to utilize and increase the service life of shower nozzle.

(2) high-pressure blast of high-speed circulating and water under high pressure are carried out abundant geomantic omen by the sprayer unit using special wind and aquaporin Mixed aerosol, forms the water smoke more tiny than traditional spray, this water smoke be it is a kind of can float mobile mist group, it is this thin The haze skyborne holdup time greatly increases than traditional spraying, increases the depositing dust area of water smoke, has to dust more preferable Suction-operated.

(3) sprayer unit cost easy to use is low (more than 100 yuan/set), jet absorption type spray mining with like product such as KPSX- Mist device for reducing dust (often covering more than 20000 yuan) saves substantial contribution.Crossheading adds up about many such as above and below a coal-face In 10 sprayings, more than 200000 yuan is saved.Meanwhile suitable for colliery main entry, coal-face (two lanes and support move frame spraying), Driving face is met head on and each transfer point of ore deposit producing coal system.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
