The utility model belongs to garbage collection technical field discloses a kind of garbage disposal station. Including foundation, station body and garbage collection device, the station body is located upper portion of foundation, the garbage collection device is located in station body. The garbage collection device includes solid collection box and waste liquid collection box, the lower part of station body is provided with through slot, the through slot is connected with filter assembly, the solid collection box is located above filter assembly, the waste liquid collection box is located below filter assembly.To solve the problem that liquid waste is contained in solid waste, sewage is not collected, leading to sewage outflow, becoming secondary pollution source.

The low-noise gas water heater shell comprises a face cover, sound absorption cotton, an outer shell, a check ring, silencing sponge, a silencing plate and a back baffle, an opening is formed in the front end of the outer shell, a water heater assembly can be placed in the outer shell, the face cover can cover the opening in the front end of the outer shell, and the sound absorption cotton is fixed to a panel and located in the outer shell. An exhaust port is formed in the top end of the shell, the check ring is annular and elastic, the outer ring of the check ring is in sealed connection with the edge of the exhaust port, the inner ring of the check ring is in sealed connection with the outer wall of the exhaust pipe, the air inlet groove is located below the groove and communicated with the groove, an air inlet is formed in the groove in a penetrating mode, and the noise reduction sponge and the noise reduction plate are fixed to the front face of the back baffle. The silencing sponge and the silencing plate are located in the air channel, air can enter the air channel from the air inlet groove and then enter the shell through the air inlet, and the silencing sponge and the silencing plate can reduce the speed of airflow in the air channel. The utility model has the advantages of simple structure and low use noise.

This application provides a discharge rack, a punch press, and a stamping system. The discharge rack is suitable for the stamping system, which includes a punch press and a soundproof enclosure. The soundproof enclosure forms a receiving space and a discharge port. The punch press is disposed within the receiving space. The discharge rack includes a turntable rotatably disposed at the discharge port. The turntable has a transfer station for receiving the workpiece output by the punch press inside the discharge port and then rotating with the turntable to the outside of the discharge port for discharge. Soundproofing components are provided around the transfer station. When the transfer station rotates to the inside of the discharge port, the soundproofing components block the discharge port. The discharge rack provided in this application, when the transfer station rotates to the inside of the discharge port to receive the workpiece output by the punch press, blocks the discharge port with soundproofing components, preventing noise from the soundproof enclosure from escaping through the discharge port, thereby improving the sound insulation effect of the soundproof enclosure.
