PS centrifuge called PS series plate discharge centrifuge, is a vertical upper discharge, intermittent operation of filtration centrifuge. PS model is a technical modification on the basis of the three-legged manual unloading centrifuge, which eliminates the suspension support structure and replaces it with professionally designed high viscosity damping agent vibration isolator. The installation process is simplified, the structure is simple, the appearance is prominent and the cleaning is convenient.
Suitable for separating suspensions containing solid particles ≥1μm. Equipped with fully closed open cover, flat stand, frequency control. Can program control and far, close control. With novel structure, simple operation, smooth running, fully closed explosion-proof, high cleanliness, in line with GMP standards.
Widely used in chemical, pharmaceutical, food, light industry and other industries. It is especially suitable for the separation of solid and liquid with high environmental cleanliness requirements, strict washing requirements and high explosion-proof grade, such as pharmaceutical, food, health products, national defense and other industries with GMP requirements.
Why use PS centrifuge?
PS centrifuge uses frequency converter to start intermittent operation, has the characteristics of smooth start, adjustable separation factor, large processing capacity, high efficiency, simple operation, fast discharge, good performance, clean environment, low labor intensity. Its reasonable design, no sanitary dead Angle, smooth transition of structural parts, surface polishing, external structural parts, fasteners, roller are made of stainless steel.
PS centrifuge has simple structure, reliable performance, reasonable design, convenient operation and maintenance, and filtration time can be mastered at any time. Filter slag can be sufficiently washed, solid particles will not be destroyed.
PS centrifuge meets the requirements of GMP for equipment, good sealing performance, can meet the requirements of sealing explosionproof, suitable for filtering toxic and flammable substances, suitable for toxic, flammable and explosive occasions, widely used in chemical, food, pharmaceutical, mining and metallurgy, environmental protection, textile printing and dyeing (fiber material dehydration and washing printing and dyeing), light industry and other industries. For example: gypsum, thiamine, glauber, iron sulfate, copper sulfate, nickel sulfate, potassium chloride, acetic acid, borax, soda ash, rubber additives, dyes, plastic raw materials; Soap, grease, various resins, salt, monosodium glutamate, food additives, starch sugar, vitamins, herbicides, insect repellent, dehydrated copper, zinc, aluminum and other mineral powder.
Advantages of PS centrifuge
① Advanced, reliable and safe technology performance. Centrifuge (including mechanical body, electronic control system) can operate safely and reliably in strong corrosive environment, long service life, easy maintenance.
② Use frequency converter to speed control. The feed and separation speed can be adjusted according to the needs of the working conditions, so as to achieve the best separation effect and stronger adaptability to the separation of materials. Because of the frequency control, no centrifugal clutch drive, avoid the trouble of frequent replacement clutch throw block, and reduce the cost of operation.
③ Energy consumption braking (equipped with braking unit and braking resistance). No mechanical contact brake device, avoid frequent replacement of mechanical brake pad trouble, reduce the cost of operation. At the same time, because there is no mechanical friction in the braking process, it is more suitable for explosion-proof occasions.
(4) Structure and liquid damping skills: the use of flat plate structure, so that the center of gravity of the machine is lower, the operation is more stable, flat plate as a frame can also be used as an operation way, the operation is more convenient; The application of liquid damping skill makes centrifuge's vibration isolation and vibration damping function better. Simplify daily maintenance and facilitate the installation and maintenance of the machine.
⑤ Optional nitrogen protection system: nitrogen protection is selected to ensure that the machine works in a safe environment.
(6) Clamshell structure and online cleaning equipment: according to the requirements of GMP standards, the centrifuge cover is planned into a large clamshell structure, maintenance and press cloth device more convenient; Cleaning equipment installed in the centrifuge cavity can be used for online cleaning of the centrifuge cavity during operation and preparation according to the process requirements, which can be useful to eliminate contamination between batches.
⑦ Humanized planning: no foundation structure, broad way of operation, portable clamshell equipment, active online cleaning equipment, explosion-proof light setting, observation mirror and mirror cleaning equipment, all kinds of warning and warning signs, so that the use and protection become more simple, proper, fully show the humanized planning thinking contained in the planning.
Viewing mirror and explosion-proof observation lamp can be configured according to user needs, in order to observe the internal operation of centrifuge.
⑨ Vibration sensing device can be configured according to user requirements for vibration protection, that is, alarm when the limit is exceeded, interlock and shut down the centrifuge and cut off the feed switch valve.
⑩ It can be equipped with explosion-proof motors and explosion-proof button boxes according to the working conditions, so as to adapt to the use of explosion-proof occasions.
PS How a centrifuge works.
When working, the suspension to be separated (or the material to be deliquid-formed articles) will be added to the centrifuge opening drum laid with the filter medium. Under the action of centrifugal force field, the suspension moves to the drum wall, where the solid particles are blocked by the filter medium and remain, forming the filter cake layer; The liquid and some finer particles are discharged from the drum through the hole opened on the drum through the gap between the filter medium and the cake, and the solid and liquid phases are separated. According to different separation processes, after forming the filter cake layer, washing and replacement liquid can also be added to wash and replace the filter cake, and then the final drying and deliquid separation can be carried out until the separation requirements are met, and the speed can be lowered or the mechanical stop can be used to discharge the filter cake from the drum manually or mechanically.
Zhonglian PS series plate discharge centrifuge is based on the artificial upper discharge centrifuge, according to the national GMP requirements for pharmaceutical equipment and improved design of liquid solid centrifugal filtration equipment. The whole machine, both internal structure and external visible surface, conforms to the hygienic equipment standards of clean room. The case is fully closed procedure operation, the working form is intermittent manual or siphon discharge. It is mainly used for solid-liquid separation of suspension with high environmental cleanliness requirement, strict washing requirement, toxic and explosion-proof grade. Widely used in chemical, food, light industry, pharmaceutical, food, health products, national defense and other industrial fields. It has good applicability to high temperature, large viscosity, small particle size, all kinds of difficult to separate suspension, fibrous materials, and the minimum particle size of separation is 1μm.
