1. 2. 工作原理

Operational Principle

主机转鼓起动运转正常后，料液从进料管进入内转鼓（螺旋体）内腔，由于离心力场的作用，料液从内腔出液口均匀流入外转鼓沉降区内腔，液相经沉降区溢流口溢出，固相则由螺旋与外转鼓的差速，将物料推向螺旋的小端进入过滤端，再经过滤端的滤网孔隙将物料中剩余的液体进行过滤并排出机体。固相则被截留在滤网内侧，再由螺旋叶片逐一推向出料口，从出料口排出。

When the host drum starts to operate, the feed solution goes into the drum cavity(the spiral) from the feed pipe. The feed solution flows into the cavity of the outer drum subsidence area equably from the inner cavity liquid outlet. The liquid phase overflows from overflow port in the subsidence area while the solid phase is pushed to the filter tip from the small part of the spiral because of the speed difference between the spiral and the outer drum. Then the remaining liquid is filtered and discharged through the sieve porosity of the filter tip. And the solid is trapped inside the filter, and then it is released to the outlet port by the spiral blades one by one and it is discharged from the outlet port.

注：如有洗涤工艺要求时，在螺旋将物料推向出料口的同时进行洗涤，能达到较好的洗涤效果。

Notes: if there is a requirement of washing process, the feed solution is washed when it is pushed to the outlet port by spiral blades and a better washing effect can be achieved.

2.适用范围   Scope of Application

该机适应范围广、对物料的适应性强，应用行业广泛：如乙二酸、乙二胺、对硝基苯胺、三氯异氰脲酸、聚氯乙烯、磷酸铵、硫酸铵、硫酸铜、富马酸、碳酸钠、硫酸钠、草酸、芒硝、柠檬酸、AH-盐、结晶苏打、大苏打、上等苏打、乳糖、蔬菜、塑料颗粒等产品的固液分离。

其主要适用范围：

1.分离的颗粒直径一般为0.05～10mm，范围在0.3～2mm的颗粒，效果尤佳；

2．分离形状为线状及晶体状的固体效果较好；

3.悬浮液和沉积固体的分离；

This equipment is widely used and it has strong adaptability to materiel. It is widely used in many industries. It has been successfully used in the solid-liquid separation of many products, such as: dicarboxyl, ethylenediamine, paranitroanilinum, trichloroisocyanuric acid, polyvinyl chloride, ammonium phosphate, ammonium sulfate, copper sulfate, fumaric acid, sodium carbonate, sodium sulfate, oxalic acid, Glauber's salt, citric acid,Ａ－Ｈsalt, crystallization soda,  sodium thiosulfate, upper soda, lactose, vegetables, plastic particlesand so on.

Main application range：

1. The separated particle diameter is generally 0.05 ~ 10mm. Better effects can be achieved when the particle diameter is 0.3～2mm.

2. It is better separated when the solid is linear or crystal.

3. The separation of suspension and deposited solids.

注意：本机可使用于一般防爆要求的场合，主机可改用防爆型异步电动机。不适用于易燃易爆物料的分离或在防爆要求较高的场合。

如客户需分离易燃易爆的物料或在防爆要求较高的场合使用，在订合同时必须明确分离介质的性质、防爆要求及采用何种防爆措施。

需要说明的是，对于离心机的生产能力，与所分离物料的理化性质（如粘度、流动性、含固量）、生产工艺、操作工人的熟练程度、离心机启动和制动方式的选用等有直接的关系。

Attention: this equipment can be used in a occasion of general explosion-proof requirement. The main engine is changed to explosion proof asynchronous motor. It is not suitable for the separation of flammable and explosive materials or in the occasion of high explosion-proof requirement.

If the client want it to be used in the separation of flammable and explosive materials or in the occasion of high explosion-proof requirement, the nature of the separated medium, explosion-proof requirements and explosion-proof measures must be clear when signing the contract.

It needs to be explained that the production capacity of the centrifuge has direct relationship with the physical and chemical properties of the material (such as viscosity, liquidity, solid content)、production engineering、skilled degree of operating workers、the selection of the starting and braking modes of the centrifuge.
