Multi-functional CLeaner

In the paper industry, "Multi-functional Cleaner" is an advanced equipment highly integrated with multiple slag removal functions. It is designed to address the removal needs of various complex impurities in the pulp. It can not only precisely and efficiently remove traditional heavy impurities such as sand grains, stones, and metal debris but also effectively separate those difficult-to-handle light impurities such as plastic sheets, foams, and waxy particles. At the same time, it also has a significant removal effect on small fiber bundles, adhesives, incompletely dissociated fiber masses, and other tiny impurities that may affect the paper quality.

Its main function is to comprehensively improve the purity of the pulp to the greatest extent, minimizing the interference and influence of impurities on the papermaking process. By effectively removing these impurities, high-quality and clean pulp raw materials are provided for the subsequent papermaking processes, thereby strongly guaranteeing the smooth progress of the papermaking process and significantly enhancing the quality and performance of the paper, enabling the produced paper to meet higher standards in terms of strength, flatness, uniformity, and printability.

Used for the removal of heavy and light impurities in the pulp.

1.Multiple Separation Mechanisms

Skillfully combines multiple advanced physical and chemical separation principles such as centrifugal separation, flotation separation, and screening filtration. When the pulp enters the equipment, the first step is that the strong centrifugal force generated by the high-speed rotation causes the heavy impurities with a larger specific gravity to move outward rapidly and be separated and discharged along a specific channel.

At the same time, the flotation device inside the equipment will generate a large number of fine and uniform bubbles. These bubbles will attach to the light impurities, increasing their buoyancy and floating to the liquid surface, thereby achieving the separation of light impurities from the pulp.

In addition, the finely designed screen structure can effectively intercept those smaller-sized impurities and fiber bundles, ensuring that only pure pulp can pass through the screen and further improving the accuracy and effect of slag removal.

2.Intelligent Adjustment

Equipped with an advanced intelligent control system composed of high-precision sensors, a powerful controller, and efficient actuators. The sensors can monitor the characteristics of the pulp in real-time, such as key parameters such as concentration, flow rate, impurity type, and content.

The controller will quickly and accurately analyze and determine the current slag removal requirements based on these real-time data by using complex algorithms and preset models.

Subsequently, the actuators will automatically and precisely adjust the operating parameters of the equipment according to the instructions of the controller, such as the rotation speed of the rotating components, the size and quantity of the flotation bubbles, the pore size and vibration frequency of the screen, etc., to ensure the best slag removal effect under different pulp conditions.

1.Pulp Inlet System

Includes a well-designed pulp inlet pipeline and a high-precision flow control device. The pulp inlet pipeline is usually made of wear-resistant and corrosion-resistant materials to ensure good performance and sealing during long-term pulp transportation.

The flow control device can precisely regulate the entry speed and flow rate of the pulp, ensuring that the pulp enters the multi-functional cleaner in a stable and uniform state, avoiding unstable slag removal effects caused by flow fluctuations.

2.Separation Chamber

This is the core area for realizing multiple separation principles, and its internal structure is extremely complex and precise. It contains high-speed rotating components such as impellers or centrifugal drums. Through their high-speed rotation, a strong centrifugal force field is generated to drive the separation movement of impurities.

The flotation device usually consists of a bubble generator, gas distributor, and agitation mechanism, which can effectively generate uniform and fine bubbles and ensure that the bubbles are fully mixed with the pulp to improve the flotation effect of light impurities.

The fine screen is usually made of high-strength, wear-resistant materials with appropriate pore sizes and is installed at a specific position in the separation chamber to achieve precise interception of small impurities and fiber bundles.

3.Slag Discharge System

Independent slag discharge ports are respectively set for heavy impurities, light impurities, and small impurities. The heavy impurity discharge port is usually located at the bottom or the lower part of the side of the equipment. Through the action of gravity and centrifugal force, the heavy impurities fall naturally and are discharged.

The light impurity discharge port is generally located near the upper liquid surface of the equipment, and the light impurities are smoothly discharged by utilizing the floating effect after flotation.

The small impurity discharge port is connected to the collection area of the screen, and the intercepted small impurities are discharged from the equipment through a specific conveying device.

4.Intelligent Control System

Composed of a series of high-precision sensors, including pressure sensors, flow sensors, concentration sensors, impurity detection sensors, etc., which can obtain various key parameters of the pulp and equipment operation in real-time and accurately.

The powerful controller usually adopts an advanced microprocessor or industrial computer, with fast data processing capabilities and complex control algorithms, which can conduct in-depth analysis and judgment of the data collected by the sensors.

Efficient actuators include electric valves, variable frequency drives, hydraulic or pneumatic actuators, etc., which can quickly and accurately adjust the operating parameters of the equipment, such as rotation speed, flow rate, pressure, etc., according to the instructions of the controller to achieve precise control of the slag removal process.
