Detailed Description

The following detailed description of the present invention will be made with reference to the accompanying drawings and examples.

As shown in the accompanying drawing 1, the utility model provides a sealed reinforced battery thick liquids mixer, including lifting unit and stirring subassembly, the stirring subassembly includes churn 1 and lower churn 2, go up churn 1 and lifting unit fixed connection in order to carry out the ascending reciprocating motion of vertical side, go up and install the (mixing) shaft 7 that extends to 1 below of churn in the churn 1, go up be equipped with on the churn 1 with go up the feeder hopper 6 of 1 inside intercommunication of churn, feeder hopper 6 top one side articulates there is sealing door 11.

The utility model discloses an application principle does, descends to 1 and the 2 locks of churn of lower churn with lifting unit, then opens sealing door 11 feeding, closes sealing door 11 after the feeding finishes, begins to stir (processes such as intaking are prior art, do not describe here). After the stirring is finished, the lifting assembly rises to drive the upper stirring cylinder 1 to leave the lower stirring cylinder 2, so that the battery slurry stirred in the lower stirring cylinder 2 is taken out.

Preferably, a vibration pump and a vibration screen (not shown in the figure) driven by the vibration pump are fixed in the feed hopper 6, and an electric valve is arranged at the joint of the feed hopper 6 and the upper stirring cylinder 1. Can disperse the raw materials of caking through the mode of vibrations feeding, leakproofness when setting up electric valve and can further guaranteeing the stirring avoids the dust to get into.

Preferably, the lifting assembly comprises a lifting platform 5, a plurality of hydraulic rods 4 arranged in the lifting platform 5, and an installation box 3 fixed on the tops of the hydraulic rods 4 and driven by the hydraulic rods 4.

Preferably, the stirring assembly further comprises a stirring motor and a transmission mechanism, the stirring motor and the transmission mechanism are arranged in the installation box 3, one end of the transmission mechanism is connected with the stirring motor, and the other end of the transmission mechanism is connected with the stirring shaft 7. In this embodiment, agitator motor level sets up, drive mechanism can be with agitator motor pivot fixed connection's worm and with worm wheel that the worm meshes, the worm wheel with (mixing) shaft 7 key-type connection. The arrangement mode of the stirring motor and the structure of the transmission mechanism can also be other existing stirring machine driving transmission modes.

Preferably, the bottom end of the lower stirring cylinder 2 is provided with a walking wheel 16, a guide rail 15 horizontally arranged is further arranged below the stirring assembly, and the walking wheel 16 is in sliding connection with the guide rail 15. And a first handle 17 is arranged on the lower mixing drum 2. After the stirring is finished, when the stirring shaft 7 leaves the lower stirring cylinder 2, the lower stirring cylinder 2 can be pulled away by pulling the first handle 17 so as to take out the slurry in the lower stirring cylinder.
