Turning cover emergency stop protection device for marine sewage pulverizer

Abstract

The invention discloses a turning cover emergency stop protection device for a marine sewage pulverizer. The device comprises a base, a turning cover arranged on the sewage pulverizer and a protection circuit, wherein the right end of the turning cove is connected with the sewage pulverizer through a rotating shaft, the left end is arranged below a magnetic switch in the protection circuit, and the magnetic switch is arranged on the base and corresponds to the left end of the turning cover in position; the protection circuit comprises a transformer, the magnetic switch, an intermediate relay KA, a stop switch TA and a fusible cutout FR; a primary loop of the transformer is connected with a 220V external alternating current power supply, the magnetic switch is connected with a coil of the intermediate relay KA in series in a secondary loop, and a normally open end of the intermediate relay KA is connected with the stop switch TA and the fusible cutout FR in series and then connected with the external power supply. With adoption of the technical scheme, the defects in the prior art are overcome; and the turning cover emergency stop protection device is simple in structure, safe and reliable, and effectively prevents the risks of equipment damage of the sewage pulverizer and worker injury due to mistaken opening and non-closing of the turning cover.

Description

technical field [0001] The invention relates to a kind of marine equipment, in particular to a cover emergency stop protection device for a marine sewage pulverizer. Background technique [0002] In the existing marine sewage pulverizers on the market, if the hopper is accidentally opened or the flip cover is not closed during operation, residues will pop up when starting up, which not only has the risk of accidentally injuring the operator, but also causes metal objects to mix into the hopper. Damage to the equipment. In addition, because the flip cover is opened, the operator's hand may stray into the hopper and be injured. Contents of the invention [0003] The purpose of the present invention is to provide a cover emergency stop protection device for a marine sewage pulverizer, which overcomes the deficiencies of the prior art, has a simple structure, is safe and reliable, and effectively prevents the cover from being accidentally opened and closed. There is a risk of...
