Mixed transportation device with self-adaptive volume

Abstract

The invention discloses a mixed transportation device with the self-adaptive volume. The mixed transportation device is characterized in that the mixed transportation device comprises a shell, a floating plate, a spiral drainage plate, a lower floating ball, a lower floating ball connection pipe, an upper floating ball connection pipe, an upper floating plate, an inlet and an outlet. The mixed transportation device has the volume self-adaption function. Compared with a traditional mixed transportation device, the device with the self-adaptive volume has the three beneficial effects that in the self-absorption process, the space of the device is narrowed, suction air is little, the idling time of a rotor of a mixed transportation pump is short, and the service life of the mixed transportation pump is prolonged to a great extent; in the mixed transportation process, the filtering space of the device is enlarged, the filtering effect is good, and fine impurity particles are deposited at the bottom of the device through the spiral drainage plate; and the device is large in sealing space and good in state, and the gas-solid-liquid mixed transportation effect is substantially improved. The mixed transportation device is high in integration level, small in occupied area, small in investment and high in running efficiency and reliability. The mixed transportation device can be independently used and can also be integrated in other systems. The device can be made to be in the movable type and is easy to install and operate.

Description

technical field [0001] The invention relates to the field of fluid transportation, in particular to a volume adaptive mixed transportation device for gas-solid-liquid multiphase. technical background [0002] At present, our urban drainage uses a rotor pump, which has the characteristics of strong self-priming ability and strong passability. However, because the rotor pump does not require water diversion, it puts forward higher requirements for self-priming time when it is used for a long time. In addition, during the drainage process, abnormal impurities such as broken shoes, plastic bags, and iron sheets in the sewage may be sucked into the pump, causing the pump to get stuck or the rotor to wear abnormally. [0003] At this stage, a filter device is installed in the front section of the pump to initially filter solid impurities, which alleviates the problem of the rotor pump being stuck to a certain extent. However, the filter device has a large space. During the self-...

Problems solved by technology

However, the filter device has a large space. During the self-priming start-up stage of the pump, the air in the filter device needs to be emptied first, which will cause the rotor to self-prime and dry for too long and cause wear and tear.
