Abstract
The utility model discloses an air hammer for shaking and striking the wall of a bin, which solves the problem that the efficiency of dredging the blockage of a hopper is lower at present. The air hammer for shaking and striking the wall of the bin is characterized by comprising an electromagnetic reversing valve, an air cylinder, a hammer head, a quick air release valve and the like; the electromagnetic reversing valve is connected with an air outlet pipeline of an air storing tank by an air inlet pipeline, is connected with one end of the air cylinder by a front air pipe, and is connected with the other end of the air cylinder by a rear air pipe and the quick air release valve; a regulating valve is arranged between the rear air pipe and the quick air release valve; the air cylinder is fixed on a base; and a piston rod in the air cylinder is connected with the hammer head. The air hammer for shaking and striking the wall of the bin has a simple structure and a low manufacturing cost; the whole air hammer is mounted outside the wall of the hopper, is not necessary to arrange a hole on the hopper, has stronger dredging capability, and is quick and convenient to mount and overhaul; the fixed-time and continuous shake is realized by an electric control system; the striking frequency is randomly set; the shake force is larger, further can be regulated, and greatly exceeds manual force; further, the air hammer is uniform in shake and has an obvious effect; the efficiency is increased by several times; and the air hammer for shaking and striking the wall of the bin is particularly applicable to the dredging of a raw coal hopper in a heat-engine plant.
Description
Affiliated technical field
The utility model belongs to the dredger in a kind of solid particle material course of conveying, belongs to a kind of hopper of clearing up or rather and stops 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 content owing to material sticks on the bulkhead material, perhaps is 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 often to run at thermal powerplant.Make the coal breakage bucket glue coal, paulin coal, knot arch, chute blockage because ash content, 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, method relatively more commonly used is that manual work is beaten 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 entering coal bunker inside and thoroughly clear up.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, and 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 through admission line; Through preceding tracheae be connected to cylinder an end, be connected to the other end of cylinder through 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, two-layer inside and outside comprising, establish some holes on the internal layer, place quieter material between two-layer.
Described solenoid directional control valve is fixed on the base through adapter plate.
The application of the utility model 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 utility model utilizes pressure gas to promote the piston rod movement in the 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 utlity model has following beneficial effect: 1, simple in structure, 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 on hopper, to punch, 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 through 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 big and scalable of the artificial sledgehammer work of simulation, vibration strength, considerably beyond artificial strength, a tup can be equivalent to 8-10 workman's working strength, practices thrift manpower greatly, and vibration strength is bigger, and effect is obvious, and work efficiency obtains several times and improves.Every hopper can be provided with 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 utility model 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 utility model comprises 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, two-layer inside and outside comprising, establish some holes 9 on the internal layer, place quieter material 10 between two-layer.
Shown in Figure 2 is the application of the utility model in the hopper mediation.On hopper 17, utilize support 19 symmetries that only (getting even number) pneumatic hammer 18 of 2-8 is installed.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, from storage tank 2 lower end bonded assembly automatic bailers 25, discharge 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 utility model.Storage tank 22 also can connect air filter, oil sprayer, makes pressure gas obtain cleaning, filter, and helps protecting cylinder 16, increases the service life.
Like this, the gas of storage tank 22 through admission line 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, make gas or in the past tracheae 3, or from the back tracheae 4 gets into cylinders 16.When gas when in the past tracheae 3 gets into cylinders 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; Tracheae 4 returns tup 11 through regulating the valves 5, when quick exhaust valve 7 gets into cylinders 16, piston rod 12 being moved backward from the back when pressure gas, and the exhausr port exhaust that itself has from solenoid directional control valve 14.Accomplish 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.
