Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a dust cleaning system with air cannon. BACKGROUND
[0002] When the melting and casting equipment collects smoke dust and unloads ash, because the air inside the dust collector ash hopper is relatively humid (the high-temperature gas generated during the working process of the melting and casting equipment cools down to the smoke dust collection area, and the condensation of water vapor is inevitable during the cooling process), the dust is easily wetted, and in addition, the inclination angle of the hopper wall of the dust collector ash hopper is limited / insufficient, which easily causes the dust to accumulate at the ash discharge port and to be dry or viscous, and the ash discharge port is easily blocked, and it is difficult for the traditional dust removal and ash unloading valve to crush and discharge the dry or viscous dust that blocks the ash discharge port.
[0003] In order to solve the above technical problems, the utility model provides a dust cleaning system with air cannon. UTILITY MODEL CONTENTS
[0004] In view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a dust cleaning system with air cannon.
[0005] In order to solve the above technical problems, the technical scheme of the utility model is: a dust cleaning system with air cannon, comprising a dust collector ash hopper, a dust discharge port is arranged at the bottom of the dust collector ash hopper, a dust removal and ash unloading valve is fixedly connected to the dust discharge port, a poke dust hole is arranged on one side of the dust collector ash hopper inside the dust removal and ash unloading valve, and a gas blowing pipe is arranged on the other side, the gas outlet of the gas blowing pipe is inclined downward and aligned with the dust discharge port, the gas inlet is connected to the gas bag of the air cannon, and the gas bag is connected to the compressed gas source.
[0006] Preferably, the shape of the dust collector ash hopper is conical with the upper part being wide and the lower part being narrow.
[0007] Preferably, the top end of the dust collector ash hopper is installed at the bottom of the dust collector box at the smoke dust collection position of the melting and casting equipment.
[0008] Preferably, the horizontal height of the poke dust hole is lower than that of the gas blowing pipe, and the poke dust hole is close to the dust removal and ash unloading valve.
[0009] Preferably, a poke dust pipe is connected to the poke dust hole, and a pipe cover is fixedly connected to the poke dust pipe.
[0010] Preferably, the angle between the axis of the poke dust pipe and the horizontal plane is 15°.
[0011] Preferably, the gas blowing pipe is composed of a straight section and a circular-arc-shaped curved section, the curved section is fixedly arranged at the inner end of the straight section, the gas outlet is the pipe opening of the curved section, and the gas inlet is the pipe opening of the straight section.
[0012] Preferably, a pulse valve is installed on the pipe between the air inlet and the air manifold, and the pulse valve is connected to a power source via an electric wire.
[0013] Preferably, the air tank is connected to a compressed air pipe via a hose and a 1 / 2-inch pipe in sequence, and the compressed air pipe is connected to a high-pressure compressed air source.
[0014] Preferably, a horizontal support platform is fixedly connected to the outer peripheral wall of the dust collector hopper, and a diagonal tie rod is fixedly connected between the support platform and the dust collector hopper, and the air bag is fixedly connected to the upper surface of the support platform.
[0015] Compared with the prior art, the present invention has the following beneficial effects: the dust removal and cleaning system with air cannon is equipped with a dust removal and ash discharge valve, a ash purging hole, and an air blowing pipe connected to the air cannon's air tank.
[0016] When the dust collector hopper can discharge ash normally through the dust removal and ash discharge valve, the ash removal hole and air blowing pipe can be temporarily discontinued. When dust accumulates at the ash discharge port and becomes dry or viscous, preventing the dust removal and ash discharge valve from discharging ash normally, the dust removal and ash discharge valve and air blowing pipe are activated. High-pressure air cannons are blown into the ash discharge port through the air blowing pipe, with intermittent blowing, to disperse the dry or viscous dust and facilitate ash discharge. If the dust cannot be discharged normally even when the air blowing pipe and dust removal and ash discharge valve are combined, the air blowing pipe is stopped, and the ash removal hole and dust removal and ash discharge valve are activated. Workers insert a long rod through the ash removal hole into the area near the ash discharge port to disperse the dry or viscous dust.
