Suction head assembly

Abstract

The invention relates to a suction head assembly, and discloses a suction head capable of collecting, scraping and gathering residual liquid at the bottom of a container and then sucking out the residual liquid. The suction head assembly is characterized in that a reducing sleeve is arranged at one end of an outer rotary drum in a sleeving manner, a limiting ring is arranged at one end of the outer rotary drum, and the limiting ring and the reducing sleeve are correspondingly clamped; multiple limiting grooves are formed in the inner side wall of the outer rotary drum at equal angles, the limiting grooves extend to the middle of the outer rotary drum from one end of the outer rotary drum, an inner driving sleeve is arranged in the outer rotary drum, multiple limiting strips are arranged onthe outer side wall of the inner driving sleeve at equal angles, and the limiting strips and the limiting grooves are correspondingly clamped; and multiple blades are arranged on the inner wall of the inner driving sleeve at equal angles, the number of the blades is at least four, the blades are obliquely arranged, the ends of the multiple blades are connected through a supporting ring, and a sealing plate is arranged at the other end of the outer rotary drum.

Description

technical field [0001] The invention relates to a suction head assembly, which relates to a suction head assembly used for collecting and suctioning liquid remaining at the bottom of a container, and belongs to the field of environmental protection equipment. In particular, it relates to a suction head assembly capable of scraping and collecting the liquid remaining at the bottom of the container, and then sucking it out. Background technique [0002] At present, when the oil is added and injected, it is added through the oil barrel, and the pump is used for suction. Since the oil barrel is a cylindrical structure with a flat bottom surface, it is easy to have residual suction during suction.

Problems solved by technology

[0002] At present, when the oil is added and injected, it is added through the oil barrel, and the pump is used for suction. Since the oil barrel is a cylindrical structure with a flat bottom surface, it is easy to have residual suction during suction. In some cases, it causes waste, especially when the oil in some oil tanks is sucked and replaced, it is necessary to collect the residue deposited at the bottom to ensure the quality of the oil in the oil tank. The nozzle is set with heavy objects so that the suction port is located at the bottom of the fuel tank as much as possible, but it is still not possible to completely remove the residual substances at the bottom, and some will set an oil discharge port at the bottom of the fuel tank, which also has unclean discharge and residues The problem is that the existing structure is complex, it cannot be used in conjunction with the existing pump body structure, the versatility is poor, and the installation and coordination are difficult

[0003] Publication number CN103670589B discloses a pumping unit, which includes a bottom bracket, an oil receiving basin, a No. 1 solenoid valve, a No. 2 solenoid valve, an oil suction gun, an oil storage tank and a hot oil tank; the oil receiving basin is supported and driven by two lifting mechanisms. Lifting; the oil outlet from the bottom of the oil receiving basin is divided into two paths, one path is connected to the hot oil tank through the oil return pipe, and the other path is connected to the oil storage tank through the oil discharge pipe, the first valve port of the No. The second valve port of the solenoid valve is connected to the vacuum generator, the vacuum generator is connected to the oil storage tank, the third valve port of the No. 1 solenoid valve is connected to the hot oil tank through the gas charging pipe; the first valve port of the No. The oil gun is connected, the second valve port of the No. 2 solenoid valve is connected to the oil storage tank through the oil delivery pipe, and the third valve port of the No. 2 solenoid valve is connected to the hot oil tank through the hot oil pipe. The structure of the device is complicated, and the bottom oil discharge adopts a flat bottom structure. Liquid flow rate blocks, there will be solid residues that cannot be drained
