Abstract
The invention discloses a bunker wall vibration air hammer, which solves the problem of lower hopper-plugging dredging efficiency at present and is characterized by comprising an electromagnetic reversing valve, an air cylinder, a hammer head, a quick exhaust valve and the like, wherein the electromagnetic reversing valve is connected with an air outlet pipeline of an air storage tank through an air inlet pipeline, connected to one end of the air cylinder through a front air pipe and connected to the other end of the air cylinder through a rear air pipe and the quick exhaust valve; an adjustment valve is arranged between the rear air pipe and the quick exhaust valve; the air cylinder is fixed on a base; and a piston rod of the air cylinder is connected with the hammer head. The bunker wall vibration air hammer has a simple structure and low manufacturing cost; the whole device is arranged outside the wall of a hopper, so openings are not required to be formed on the hopper, the dredging capability is higher and the bunker wall vibration air hammer is quick and convenient to install and maintain; due to an electric control system, regular and continuous vibration can be realized and the vibration frequency can be set randomly; furthermore, the vibration strength is higher, can be adjusted and much higher than manual strength; the vibration is uniform and an effect is outstanding, so the working efficiency can be improved by multiple times; and the bunker wall vibration air hammer is particularly applicable to dredging of raw coal bunkers of thermal power plants.
Description
Affiliated technical field
The invention belongs to the dredger in a kind of solid particle material course of conveying, belong to a kind of hopper of clearing up or rather and stop up and to make the unobstructed device of mass transport.
Background technology
In the solid material process of conveying powdered, granular, block or its mixture, big, the more high reason of viscosity of high humidity, ash owing to material, material is sticked on the bulkhead, perhaps be blocked in the containers such as bunker or awl bucket, perhaps knot encircles in hopper, cause cutout, influence normally continuing of producing and carry out, particularly carry in the raw coal process at thermal powerplant often to run into.Make the coal breakage bucket glue coal, paulin coal, knot arch, chute blockage because ash, moisture, the pressure of top coal are easy to make raw coal to be squeezed into piece, produce potential safety hazard, influence unit generation.
At present, relatively Chang Yong method is manually to beat headwall with sudden force with sledgehammer, and this relatively produces effect to paulin coal in short-term; to the paulin coal time long then can not satisfy field requirement; there is personal safety hidden danger in scaffolding, or shuts down and to enter coal bunker inside and thoroughly clear up.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of simple in structure, mediation efficient bulkhead rapping pneumatic hammer higher, easy to install is provided.
Described technical scheme is such: comprise solenoid directional control valve, cylinder, tup, quick exhaust valve etc., solenoid directional control valve connects the outlet pipe of storage tank by admission line, by preceding tracheae be connected to cylinder an end, be connected to the other end of cylinder by back tracheae and quick exhaust valve, be provided with between back tracheae and the quick exhaust valve and regulate the valves; Cylinder is fixed on the base, and the piston rod in the cylinder connects tup.
Also be provided with silencer cover on the described base, comprise inside and outside two-layerly, establish some holes on the internal layer, place quieter material between two-layer.
Described solenoid directional control valve is fixed on the base by adapter plate.
The application of the present invention in the hopper mediation, symmetry is installed 2 or 4 or 6 or 8 pneumatic hammers on hopper, and pneumatic hammer connects storage tank.
Described storage tank is installed in hopper side wall with suspension bracket.
Described built in gas tank is put the steel wire tennis, and the lower end connects automatic bailer.
The present invention utilizes pressure gas to promote the interior piston rod movement of cylinder, drives the tup high-speed motion, and the inertial impaction hopper steel wall that tup produces produces the vibration ripple and makes the material in the hopper be subjected to displacement, fall.
The present invention has following beneficial effect: 1, simple in structure, and low cost of manufacture.Easy for installation: whole device is installed in outside the bucket wall, and any facility is not set in hopper, can guarantee fully that material does not have any resistance to flow, and the mediation ability is stronger.Overhaul quick and easy: do not need to punch at hopper, have fault to overhaul at any time, also do not need blowing out or burn empty coal bunker for coal bunker.
2, the work-hours that can set solenoid directional control valve by electric control system impacts frequency in any setting to realize regularly vibration.Both can work automatically, but manual work again; But both continuous workings, but intermittent use again; Both can control on the spot, remote controlled again.
3, the artificial sledgehammer work of simulation, vibration strength are big and can regulate, and considerably beyond artificial strength, a tup can be equivalent to 8-10 workman's working strength, saves manpower greatly, and vibration strength is bigger, and effect is obvious, and work efficiency obtains the several times raising.Every hopper can arrange 1 to 8 pneumatic hammer, symmetry, staggered installation up and down, and several tups clash into the diverse location of same hopper simultaneously, are equivalent to 8 to 32 workmans and work simultaneously.
4, the present invention is specially adapted to the mediation of the former coal bunker of thermal power plant, can solve operating paulin coal, knot arch, chute blockage phenomenon effectively, also can be used for mediation, the block clearing of equipment such as grey slag bucket, grey pipeline, feed pipeline.

The specific embodiment
As shown in Figure 1, the present invention includes solenoid directional control valve 14, cylinder 16, tup 11, quick exhaust valve 7 etc.
For the steel wall of avoiding tup 11 vibration hoppers 17 produces bigger noise, on base 1, also be provided with silencer cover 8, comprise inside and outside two-layerly, establish some holes 9 on the internal layer, place quieter material 10 between two-layer.
Figure 2 shows that the application of the present invention in the hopper mediation.Utilize support 19 symmetries that only (getting even number) pneumatic hammer 18 of 2-8 is installed at hopper 17.The source of the gas of pneumatic hammer is from connecting storage tank 22.
In the described storage tank 22 steel wire tennis 24 is set, plays the profit filtration.If contain moisture, oil in the pressurized air, when it passes through steel wire tennis 24, can be attached on the steel wire tennis, moisture, oil form water droplet, oil droplet, and the automatic bailer 25 that connects from storage tank 2 lower ends is discharged water, oil in the storage tank automatically.
Pressure gas in the storage tank 22 is from the source of the gas of power plant, or the Air compressor air feed is set.For guaranteeing more stable gas and air pressure, the preferred Air compressor of the present invention.Storage tank 22 also can connect air filter, oil sprayer, makes pressure gas obtain cleaning, filter, and is conducive to protect cylinder 16, increases the service life.
Like this, the gas of storage tank 22 through air inlet pipe 15, solenoid directional control valve 14, preceding tracheae 3 or after tracheae 4 arrive cylinders 16.The switching direction of electric control system control solenoid directional control valve 14 makes gas or the past tracheae 3 or enters cylinder 16 from back tracheae 4.When gas when in the past tracheae 3 enters cylinder 16, promote piston rod 12 and travel forward, drive tup 11 vibration bucket walls, and from deflation hole 6 exhausts of quick exhaust valve 7; When pressure gas from back tracheae 4 through regulating the valves 5, when quick exhaust valve 7 enters cylinder 16, piston rod 12 being moved backward, return tup 11, and the exhausr port exhaust that itself has from solenoid directional control valve 14.Finish a vibration thus, and tup 11 is got back to starting point.
When reality is used, consider the reliability of coal bunker wall, also can impact guar plate 20 to gain in strength in the position welding of tup 11 bump hoppers 17.
