Four-motor-driving and double-screen-fence balancing type horizontal vibrating de-watering centrifuge and parameter determining method

Abstract

The invention provides a four-motor-driving and double-screen-fence balancing type horizontal vibrating de-watering centrifuge. The four-motor-driving and double-screen-fence balancing type horizontal vibrating de-watering centrifuge comprises a material charging and discharging mechanism, a screen fence box body mechanism, a rack, a de-watering transmission, a power mechanism, a vibration exciter and a vibration absorbing mechanism, wherein a de-watering device is mounted on the rack and is subjected to vibration isolation through the vibration absorbing mechanism; the material charging and discharging mechanism and the screen fence box body mechanism are connected as a whole to be used as an outside component being out of vibration; the de-watering transmission mechanism is connected with the screen fence box body through a shearing rubber spring, and a motor-belt wheel device is used as a power mechanism for supplying power to the de-watering transmission mechanism; a vibrating motor and a seat body form the whole vibration exciter which is mounted to the de-watering transmission mechanism to supply vibration exciting force to the de-watering mechanism. When the device is in working, materials are guided to screen fences through the material charging and discharging mechanism and are dewatered under the vibration and centrifuging effects. According to the four-motor-driving and double-screen-fence balancing type horizontal vibrating de-watering centrifuge, a three-component four-motor-driving dynamic model is used as the design model, and on that basis, a novel vibration mechanism model and a design parameter determining method thereof are provided.

Description

technical field [0001] The invention relates to a vibrating centrifugal dewatering machine, in particular to a four-machine-driven double-screen bar balanced horizontal vibrating centrifugal dehydrating machine and a parameter determination method. Background technique [0002] The coal preparation plant has a large amount of washed fine coal that needs to be dehydrated by a centrifugal dehydrator. In the 1950s, my country began to use a vertical scraper discharge centrifugal dehydrator for dehydration, and the obtained fine coal products had low moisture content. However, this kind of equipment has problems such as small feed size, low processing capacity, high energy consumption, high installation height, serious oil leakage, fast wear of the screen basket, inconvenient inspection and maintenance, high plant investment and production costs, etc. [0003] The horizontal vibrating centrifugal dehydrator is the key equipment used in the coal preparation plant for dehydration...
