Description

Air pipe filtering device for rock drill

Technical Field

The utility model relates to a radar assembly technical field, concretely relates to trachea filter equipment for rock drill.

Background

The working principle of the rock drill is as follows: compressed air output by the air compressor is used as power, and the reciprocating motion of the piston is controlled by an air distribution valve of the rock drill, wherein the air distribution valve is the heart of the rock drill. During the stroke, the piston impacts the drill rod and the drill bit to chisel rock; during return stroke, the piston drives the drill rod and the drill bit to rotate for a certain angle, and the drill rod and the drill bit continuously impact and rotate to make the drill bit chisel a round blast hole on the rock.

There are two main ways for small impurities to enter the rock drill: the method has the advantages that firstly, fine sundries are inevitably brought into the air pipe elbow and enter the rock drill in various mining, metallurgy, railway, traffic, hydropower and construction sites; and secondly, rusty materials, corrosion stripping materials and iron slag in a compressed air conveying pipeline or an air storage tank enter an air pipe elbow of the rock drilling machine along with the air conveying pipeline and are conveyed into the rock drilling machine.

If the compressed air contains peeled iron slag, stone slag or sand grains which enter the valve and the matching surface is scratched or the pore channel is blocked, the air distribution valve loses the function. Therefore, the whole rock drill cannot work normally, the normal rock drilling time is delayed, the production efficiency of an operator is reduced, and the normal production is influenced.

The utility model discloses an it sets up the filter that becomes certain slope contained angle with the axis of trachea elbow in CN 201420496522.0 utility model patent "an air filter for rock drill". The drawbacks of this structure are: when cleaning up the impurities or cleaning up the filter, the filter must be disassembled for cleaning, and the removal and filtration of the impurities are time-consuming.

Problem to among the above-mentioned technical background, the utility model aims at providing a trachea filter equipment for rock drill is convenient for clear up filter equipment to in the improvement to the filter effect of trachea interior air, the normal work of protection rock drill.

In order to realize the above purpose, the utility model discloses a technical scheme be:

the utility model provides a trachea filter equipment for rock drill, includes the trachea body with the rock drill intercommunication, the one end of trachea body is provided with the air inlet be close to on the trachea body the one end of air inlet be connected with the erection joint of trachea body's axis one-tenth certain slope contained angle, demountable installation has the filter cylinder in the erection joint, the front end of erection joint is connected with the sealed lid of detachable, the upper end of filter cylinder is provided with the extension rod, the extension rod passes sealed lid extends to the outside of sealed lid, be provided with on the lateral wall of trachea body and be located the blowback hole of filter cylinder top, just be provided with sealed the pad between extension rod and the sealed lid.

Furthermore, the lower end opening of the filtering roller is communicated with the air inlet, and air entering through the air inlet enters the other end of the air pipe body through the filtering roller.

Further, the sealing cover is connected with the mounting device through threads.

Furthermore, the back-blowing hole and the axis of the air pipe body form a certain inclined included angle, so that air is obliquely blown into the air pipe body downwards through the back-blowing hole.

Further, a detachable filter element is arranged at the air inlet.

The technical effects of the utility model reside in that:

1. use the utility model discloses during the trachea filter equipment, compressed air gets into the trachea body from the air inlet, and the air filters through filtering drum, uses after a period to drive filtering drum through rotating the extension rod and rotates, makes one side of filtering drum rotate to communicate with the trachea body, and make full use of filtering drum's whole cross filter surface not only improves filtration efficiency, and can prolong filter equipment live time.

2. When needs clearance, only need blow in highly-compressed air through the blowback hole, carry out the blowback to filtering roller, will block up the impurity of cylinder and blow off, rotate filtering roller simultaneously, can carry out abundant cleanness to filtering roller, shorten impurity clearance time, reduced the number of times that the rock drill shut down and maintained.

Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

Referring to the attached drawings 1-2, a trachea filter equipment for rock drill includes the trachea body 1 with the rock drill intercommunication, the one end of trachea body 1 is provided with air inlet 2 be close to on the trachea body 1 the one end of air inlet 2 be connected with the erection joint 3 of trachea body 1's axis certain slope contained angle, demountable installation has filtering drum 4 in the erection joint 3, the front end of erection joint 3 is connected with the sealed lid of detachable 5, filtering drum 4's upper end is provided with extension rod 6, extension rod 6 passes sealed lid 5 extends to sealed outside of lid 5, be provided with on trachea body 1's the lateral wall and be located the anti-hole 8 that blows of filtering drum 4 top, just be provided with sealed 7 of filling up between extension rod 6 and the sealed lid 5.
