Detailed Description

The following describes in detail a preferred embodiment of a core shooter noise reduction and dust removal device according to the present invention with reference to the accompanying drawings.

As shown in fig. 1 and 2, the silencing and dust removing device for the double-open core shooter comprises a tank body 1, a reversing valve 4, a gas storage tank 5, a sand shooting head 6 and a hot core box mold 7, wherein a labyrinth baffle structure, a sand-back prevention cover 103 and a sand collecting hopper 104 are arranged inside the tank body 1, an exhaust cloth bag 2 is arranged at the top of the tank body 1, a discharge valve 3 is arranged at the bottom of the tank body 1, the reversing valve 4 is arranged at the upper part of the gas storage tank 5, compressed air jets coated sand into a cavity 701 of the hot core box mold 7 through an air outlet pipe 401 and the sand shooting head 6 after an air inlet 403 of the reversing valve 4 is opened, the air inlet 403 of the reversing valve 4 is closed after sand shooting is finished, an air outlet 404 is opened, tail gas discharged from sand shooting enters the tank body 1 through an exhaust pipe 402, gas and dust in the tail gas are buffered and settled through the labyrinth baffle structure, gas buffering energy consumption is reduced, and is filtered and discharged into the air through the exhaust cloth bag 2; the dust settles to the sand collecting hopper 104 and is discharged through the discharge valve 3 for recycling.

The reversing valve 4 is a three-way electromagnetic reversing valve, and can automatically adjust the opening and closing of the air inlet 403 and the air outlet 404 according to a core making program of the hot core box core making machine.

Wherein, the labyrinth baffle structure is composed of a layered baffle 101 and a middle clapboard 102. The gas and dust in the tail gas play a role in buffering and settling when passing through the labyrinth baffle structure, so that the direct impact and abrasion of the tail gas on the inner wall of the tank body 1 are prevented, the direct impact on the exhaust cloth bag 2 is also avoided, the gas buffering energy consumption is reduced, the air flow noise is reduced, and the dust is settled to the sand collecting hopper 104.

Wherein, the discharged dust contains most recyclable coated sand particles.

The sand-back prevention cover 103 is of an umbrella-shaped structure, is arranged at the upper part of the sand collection hopper 104, plays a role in preventing dust which is settled in the sand collection hopper 104 from being blown back, and prevents gas from impacting and carrying fallen dust.
