At present, wax pulp is often stirred by an L-shaped pulp stirring machine, which mainly comprises the steps of containing the wax pulp by a pulp stirring barrel, driving the pulp stirring barrel to rotate by a driving device, driving the wax pulp in the pulp stirring barrel to rotate together, and stirring the wax pulp by an L-shaped pulp stirring rod in the pulp stirring barrel; as the wax slurry stirring device needs to adapt to wax slurry stirring operations with different quantities, the height of a stirring blade at the bottom of a slurry stirring rod is adjusted by driving the slurry stirring rod to vertically move through the principle of a lifting rod sliding block.

However, in the process of stirring the slurry, the wax slurry in the slurry stirring barrel is easy to splash out and is stuck to the lifting device of the existing slurry stirring rod and the lifting rod; can fall the partial screw thread cover on the lifter after gluing the wax thick liquid solidification on the lifter to influence the normal lift of stirring thick liquid pole, need carry out regular clearance to the wax thick liquid on the lifter specially, influence work efficiency and operate inconveniently. Moreover, the wax slurry can be adhered to the outer side wall of the slurry stirring barrel, even the part of the wax slurry close to the inner wall of the slurry stirring barrel can be adhered to the inner wall of the slurry stirring barrel, the cleaning is needed, and particularly when the variety of the wax slurry needs to be replaced, the cleaning is needed, and the working efficiency is affected.

In addition, because the size stirring barrel is large, the weight of paraffin in the size stirring barrel is large, the required torque is large when the size stirring barrel and the paraffin in the size stirring barrel are driven to rotate, and the problem of large energy consumption exists in the existing size stirring barrel driving device.

Therefore, the existing L-shaped pulper has the problems of easy wax pulp sticking, inconvenient operation and large energy consumption.
