Embodiment

[0021] like figure 1 Shown, an input end of the fish collecting tank 5 of the present invention is connected with the fish suction pipe 1, and the other input end is directly connected with the vacuum pump 11 by the suction and exhaust pipe 9, and is also provided with a pneumatic knife on this fish suction pipe 1 simultaneously. Valve 2, and a pneumatic butterfly valve 8 is provided on the suction and exhaust pipe 9.

[0022] At the same time, a supplementary gas pipe 14 communicated with the suction and exhaust pipe 9 is also provided at the input end of the pneumatic knife valve 2 . In order to facilitate air supply, the connection between the air supply pipe 14 and the suction and exhaust pipes 9 should be located at the front end of the pneumatic butterfly valve 1 8 , that is, between the pneumatic butterfly valve 1 8 and the vacuum pump 11 . Correspondingly, in order to control the conduction and blocking of the supplemental gas pipe 14 , a check valve 13 and a second p...

Abstract

The invention discloses a vacuum fish-pumping system of a ship, which comprises a pneumatic knife valve (2) and a fish collecting tank (5) connected through a fish-pumping tube (1). The vacuum fish-pumping system is characterized in that the input end of the fish collecting tank (5) is connected with a vacuum pump (11) through an intake and exhaust tube (9), the input end of the pneumatic knife valve (2) is connected with the intake and exhaust tube (9) through an air supplementing tube (14), a first special plate type check valve (3) connected with the pneumatic knife valve (2) is also arranged in the fish collecting tank (5), and a second special plate type check valve (6) is arranged at the output end of the fish collecting tank (5). Since the second special plate type check valves are adopted instead of the traditional large electric / pneumatic knife valves, the invention not only reduces the equipment cost and saves the energy, but also reduces risks of clamping and damaging the fish.

Description

technical field [0001] The invention relates to a fish pumping system, in particular to a marine vacuum fish pumping system. Background technique [0002] At present, vacuum technology is widely used in foreign large-scale trawler fish suction devices to unload fish, which can not only effectively reduce the damage rate of fish during transportation, but also improve the quality and conveying speed of fish. However, the self-developed fish suction devices in my country generally suffer from low power consumption, long fish pumping and discharging cycle, small fish-water ratio that can be extracted, unable to seal the fish tank, and high fish damage rate when extracting fish. Defects. SUMMARY OF THE INVENTION [0003] The object of the present invention is to overcome the defects of the current fish suction devices such as low power usage, long fish pumping and draining cycle, small fish-water ratio that can be extracted, inability to seal the fish compartment and high fish...
