Problems solved by technology

[0003] At present, most of the similar rotors at home and abroad adopt a structure in which both the rotor core and the helical blades are conical. The curved surface of such a structure is complex in shape and difficult to process. It is difficult to guarantee the processing accuracy, and the ideal pulping effect cannot be achieved. higher
The overall structure of the two high-consistency hydraulic pulper rotors disclosed in Chinese patent 02254058.x and 200420052600.4 tends to be simple. Although the energy consumption is reduced, there are still improvements to achieve a better pulping effect and save energy. energy consumption

Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings.

[0013] A helical rotor of a high-concentration hydraulic pulper includes a rotating core 1, a helical blade 2, a toothed blade 3 and a chassis 4. The upper part of the rotor core 1 is a cylinder, and the lower part is a cone. The cylinder part is welded with three single-line spiral blades. The spiral blades are positive helicoids and are evenly distributed on the rotor core; On the chassis and connected with the spiral blade, the fine teeth on the toothed blade are evenly distributed, which mainly shreds the waste paper, and also transports the slurry to the inner wall of the tank to form an overall vortex circulation of the slurry flow field ; The main function of the chassis is to connect with the transmission.

Said helical rotor includes the following several portions: rotor core, helical blades, toothed blades and base plate. The upper portion of said rotor core is made into the form of circular cylinder and its tower portion is made into the form of cone, the bottom portion of said cone body is connected with the described base plate, the circular cylinder body portion of said rotor core is equipped with three helical blades, the toothed blades are placed on the base plate and connected with the helical blades respectively. Besides, said invention also provides the working principle of said hydrapulper and its operation method.

Description

technical field [0001] The invention relates to the field of pulping and papermaking, in particular to a helical rotor of a high-concentration hydraulic pulper. Background technique [0002] Pulping is the first operating unit in the waste paper pulping process, and it is also a crucial unit. The rotor of the pulper is the key to the design of the pulper, and its structure directly affects the pulping effect and energy consumption of the pulper. The main function of the rotor is to transfer energy to the slurry, generate a high-strength shear force field, and force the slurry to generate turbulence and vortex circulation, so as to achieve the purpose of crushing the slurry. [0003] At present, most of the similar rotors at home and abroad adopt a structure in which both the rotor core and the helical blades are conical. The curved surface of such a structure is complex in shape and difficult to process. It is difficult to guarantee the processing accuracy, and the ideal pu...
