Description
Technical field
The utility model relates to papermaking material sieving technology field, particularly relates to a kind of drum sieve.
Background technology
Waste paper is one of China paper industry main raw material source, if but the impurity in the wastepaper as raw material is not processed the quality that will affect new paper.Impurity in the waste paper mainly contains the impurity such as hot-melt object, plastic sheeting, sicker and metal sundries, so must process the manufacturing that just can be applied to new paper through removal of impurities behind the waste paper pulping.Drum sieve is a kind of for granule materials is screened separation, paper pulp is screened the device of separation.Yet the utilization rate that the screening effect of traditional round shaft screen is relatively poor, be difficult to improve to greatest extent material.
The utility model content
The purpose of this utility model is to avoid weak point of the prior art and provides a kind of screening effect good drum sieve.
The purpose of this utility model is achieved through the following technical solutions.
A kind of drum sieve comprises motor, shell and screen cylinder, and motor drives with screen cylinder and is connected, and screen cylinder is arranged at the inside of shell, and is provided with the water slurry recycling cavity between screen cylinder and the shell, and the bottom of shell is provided with the plasma discharge mouth that is communicated with the water slurry recycling cavity; The inside of screen cylinder is provided with spiral helicine flight, and flight arranges around the axis of screen cylinder.
Wherein, the inwall of screen cylinder is located in the flight weldering.
Wherein, also comprise power transmission shaft and belt, the output of motor drives with an end of power transmission shaft and is connected, and the other end of power transmission shaft is connected by belt transmission with screen cylinder.
Wherein, the number of belt is two, and two belts are located at respectively the two ends of screen cylinder.
Wherein, screen cylinder also is provided with jetter, and the delivery port of jetter is towards the sieve aperture setting of screen cylinder.
Wherein, an end of screen cylinder is provided with charging aperture, and the other end of screen cylinder is provided with slag notch.
Wherein, screen cylinder is one to be provided with the cylinder of sieve aperture.
The beneficial effects of the utility model: a kind of drum sieve, it comprises motor, shell and screen cylinder, and motor drives with screen cylinder and is connected, and screen cylinder is arranged at the inside of shell, and be provided with the water slurry recycling cavity between screen cylinder and the shell, the bottom of shell is provided with the plasma discharge mouth that is communicated with the water slurry recycling cavity; The inside of screen cylinder is provided with flight, and flight arranges in the shape of a spiral around the axis of screen cylinder.Compared with prior art, be provided with helical blade in the screen cylinder of the present utility model and prolong the slag slurry by the time of drum sieve, the impurity of slag slurry is separated better with fiber, screening effect is good.
Description of drawings
Utilize accompanying drawing that the utility model is described further, but the content in the accompanying drawing does not consist of any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of drum sieve of the present utility model.
