Description
Technical field
This utility model relates to coalmine ventilation and security fields, spraying system between specifically a kind of working face face frame
System.
Background technology
Fully-mechanized mining working is as the key operation place of mine, and owing to physical features is relatively low, air circulation is poor, and personnel equipment
Concentrate, be the most all one of the main dust production resource in each big mining area, bring to environmental conservation and the healthy of staff
Huge infringement.For responding the call of national energy-saving pollution treatment, many coal mining machines when dispatching from the factory, all can be equipped with a set of accordingly
Spray dust remover.But owing to being affected by various concrete operating modes in actual production practices, cause dedusting depositing dust to be imitated
Fruit is the most inconspicuous, makes troubles the most also can to normal production of staff.
Spraying between existing working face face frame and be mostly arranged on the middle part of fully mechanized mining supporter back timber, nozzle down, is opened
Time water smoke spray to transporter from top to bottom, in use there are following problems in this kind of mounting means:
1, using this kind of mounting means, when between frame, spraying is opened, water smoke easily spills to support foot and cable trough, causes frame
Foot is wet and slippery, and pedestrian's difficulty, people easily slides into traumatic injury；Cable is moist, and insulation reduces existence electric leakage risk.Simultaneously in cable and cable trough
And laying dust is difficult to clear up on pedestrian's handrail；
2, when people passes through from the face of adopting, easily drenching clothes, therefore, workman is reluctant to open use；
3, maintenance inconvenience, maintainer is dangerous.During maintenance, changing pipeline or shower nozzle, personnel need to enter coal wall side, fortune
Defeated machine needs to stop, and Ren Guan mountain to be had prevents coal wall wall caving from hurting sb.'s feelings；
4, during the up coal cutting of coal machine, being positioned at the support face guard above coal machine needs to regain, the water smoke of ejection of now spraying
Being sheltered from by face guard, spraying does not has effect, does not reaches dust-laying effect；
5, the flexible pipe that spraying uses is also easy to be regained extruding breakage by side guard plate, causes spraying normally to use.
Utility model content
In order to overcome, the operating process that between tradition working face face frame, sprayer unit exists is complicated, dust removing effects is the best, easy
Drench frame foot cause ground wet and slippery, easily drench pedestrian affect job schedule, maintenance change difficulty etc. a series of shortcoming, this practicality
Spraying system between the novel working face face frame providing a kind of optimization, by rational mounting means and intelligentized sensing system
System can realize opening and closing automatically of sprayer unit, and economize in raw materials, safeguard that simple, dust removing effects more preferably and not affects work
The normal operating situation of personnel.
For achieving the above object, technical solution adopted in the utility model is:
Spraying system between a kind of working face face frame, including the dust sensing dress being arranged on fully mechanized mining supporter front-axle beam face guard
Putting and be arranged in the sprayer unit on gear coal tong plate, described sprayer unit includes the straight pipe being vertically arranged and controls straight
The electrically operated valve of siphunculus, one end of straight pipe connects two high velocity projectors arranged towards coal wall side, two high velocity projectors and water
Square to all in 45 ° of angles and one upwards one downwards, the other end of straight pipe is by an anchor tip with high-pressure rubber pipe even
Connecing, the signal output part of described dust induction installation connects an Infrared Projector, is provided above one at gear coal tong plate
Corresponding infrared signal receiver, in infrared signal receiver is transmitted to after receiving the signal that Infrared Projector sends
The controller in portion, the outfan of controller is connected with electrically operated valve and controls unlatching and the Guan Bi of electrically operated valve.
As a kind of preferred version, described gear coal tong plate offers downwards a V-groove, high velocity spray along the axis of upper topside
Head is fastened in V-groove.
As a kind of preferred version, described electrically operated valve uses electrical ball valve.
Beneficial effect:
Spraying system between the frame after 1, this utility model improves, a part of water smoke directly sprays to transporter, another part water
Mist directly sprays to coal wall, directly moistening coal body and dust, and dust-proof, dust-laying effect significantly improves；
Spray between the frame after 2, this utility model improves, be all arranged on gear coal tong plate because of spray power valve and high speed nozzle
On, when changing and keep in repair, personnel are without entering the construction of coal wall side, add the safety of maintenance；
Spraying system between the frame after 3, this utility model improves, because spraying is only sprayed water towards coal wall and transporter direction, frame foot
The most wet and slippery, no longer moist on cable, it is possible to reduce personnel's traumatic injury and cable leakage accident；
Spraying system between the frame after 4, this utility model improves, because have employed dust induction installation and electrically operated valve, can be real
That now sprays automatically turning on and closing, thus suppresses the diffusion of dust in time, is more beneficial for environmental protection and health；
Spraying system between the frame after 5, this utility model improves, high-pressure rubber pipe props up owing to eliminating to walk around to combine to adopt when mounted
The distance of frame, so that its usage amount significantly reduces, more originally can save 1/2, be greatly saved material, meanwhile, and high velocity spray
Mouth and straight pipe can be protected by gear coal tong plate, are hardly damaged, it is possible to utilization and recycle.
