Description
Technical Field
The invention relates to the field of papermaking and pulping, in particular to a continuous double-vortex hydraulic cleaner.
Background
The hydraulic cleaner is used for removing a large amount of light and small amount of heavy impurities in paper pulp in the waste paper treatment process of the paper pulping industry, and when the hydraulic cleaner works, along with the rotation of a rotor, the pulp put into the cleaner is subjected to hydraulic impact, mechanical tearing of an impeller and mechanical untangling between the impeller and a sieve plate, so that strong shearing, friction and kneading actions are generated, the pulp in the cleaner is fully broken, and finally the pulp is dissociated into fibers.
As shown in FIG. 1, the whole layout of the existing hydraulic cleaner is in a horizontal structure, firstly, slurry cannot form vortex in a horizontal slurry tank 1, so that strong collision and scattering of the slurry cannot be realized, and the slurry is not easy to break; secondly, a good pulp outlet 3 and a heavy slag outlet 5 of the pulp tank 1 are arranged at the lower part of the pulp tank, and the separation of the good pulp and impurities is incomplete. The structure also determines that the discharge of the good pulp and the impurities is intermittent, thereby greatly reducing the production capacity and the efficiency; third, as shown in fig. 1, the impeller 2 has a larger core, and the blades are higher and shorter, so that the flow resistance is increased, and the energy consumption of the device is further increased.
Therefore, how to provide a cleaning machine capable of solving all or part of the above-mentioned defects is a technical problem that needs to be solved by the person skilled in the art.

Preferably, the inclination angle of the central axis of the first slurry cavity relative to the ground is 45-55 degrees, the inclination angle can be properly adjusted according to the amount of heavy slag in the slurry, and when the amount of heavy slag is more, the angle can be increased to improve the collection effect of the heavy slag.
Preferably, the slurry inlet is arranged on the side wall of the first slurry cavity close to the lower end, the good slurry outlet is arranged on the side wall of the first slurry cavity close to the upper end, and the heavy slag outlet is arranged at the lower end of the second slurry cavity.
The good slurry outlet and the heavy slag outlet are respectively designed on the side wall, close to the upper end, of the first slurry cavity and the lower end of the second slurry cavity, so that the complete separation of the good slurry and the heavy slag can be realized during operation, and continuous slurry outlet is realized; compared with the existing hydraulic cleaner, the energy-saving efficiency can reach about 25%, and the productivity can be improved by 10-30% under the same breaking degree for the hydraulic cleaner with the same specification.
Further, the slurry treatment device also comprises a supporting seat, one end of the supporting seat is arranged on the ground, and the other end of the supporting seat is connected with the outer side wall of the first slurry cavity and/or the outer side wall of the second slurry cavity.
