Inflow Fine Coarse Horizontal Pressurized Pressure for Pulping Equipment Fiber Fractionating Screen

Product Description

Pulp Equipment Stainless Steel Pressure Screen for Paper Mill 
 

Product Description

The pressure screen adopts the upward flow structure design of feeding slurry at the bottom, discharging heavy slag at the bottom, and discharging light slag at the top, which effectively solves the problem of removing impurities. In the pulp production process, the light impurities in the pulp and the air in the pulp are naturally raised to the top slag discharge port to be discharged, and the heavy impurities can settle to the bottom to be discharged as soon as they enter the machine body. In this way, on the one hand, the residence time of impurities in the screen area is effectively shortened, the possibility of impurity circulation is reduced, and the screening efficiency is improved; on the other hand, the damage to the rotor and the screen drum caused by heavy impurities is prevented, and the service life of the equipment is prolonged.
There are mainly inflow pressure screen, outflow pressure screen, upflow pressure screen

The structure of the pressure screen
1. Screen Basket: The sieve drum with a width of H0.15mm for the fine sieve screen is grooved on an 8mm thick steel plate using water jet cutting technology to form excellent round holes and burr-free notches, which will not be the same as machine washing and grinding notches. Stress and groove end cracks are generated. And can provide the hardness of the network technology to improve the anti-wear performance.
2. Rotor : 3-4 rotors are installed on the fine pulp rotor, and the balance is strictly corrected after assembly so that the rotor does not vibrate when it rotates at high speed. The rotor is installed on the main shaft, the rotor is installed on the rotor through the screw rod, and the gap between the rotor and the screen drum can be adjusted. The coarse screen rotor adopts a drum-type external rotor structure and corrects the dynamic balance. This structure can prevent impurities from wrapping around the rotor and affecting the normal operation of the equipment.
3. Shell: It consists of an upper cover and a cylinder body, and the lower part of the cylinder body is provided with a tangential slurry feeding pipe. There is a slurry outlet pipe in the middle of the cylinder, and a slag discharge port and a flushing water port are provided on the upper cover.
4. Transmission device: including motor, pulley, v-belt, belt tensioning device, main shaft, and bearing.

The Pressure Screen Application
1. The Paper Machine Waste Paper Recycling Pulp Equipment Inflow Pressure Screen can make light impurities and the air in the stock naturally go up to the outlet, while the heavy impurities deposit in the bottom and then be discharged, which greatly reduces the friction of the rotor and screen frame.

2. The utilization of upflow structure design eliminates the turbulence that may cause the vibration of the screen. In addition, the upflow design can also prevent impurities from mixing with the stock. 

3. The pulp screen is known for its large production capacity and wide range of applications. It is applicable to the stock of various consistencies, like medium consistency stock (2%-3.5%) and low consistency stock (0.5%~1.2%).

4. High screening efficiency and low power consumption.
