Vertical scraper central unloading and filtering centrifugal machine

Abstract

The invention belongs to a solid-liquid separation device, and relates to a vertical scraper central unloading and filtering centrifugal machine which comprises a fixed shaft fixed at the principal axis. A shaft hole of the fixed shaft serves as an unloading channel. The fixed shaft is connected to a flange and installed on a machine base plate. A bearing external drum is connected with a drum andprovided with a belt groove. A belt wheel is driven by a motor. A transmission belt drives the bearing external drum and the drum to rotate. The upper end of a scraper rod is provided with a feed port, and the vertical reciprocating movements are driven by a vertical oil cylinder. A scraper rod rotating device is composed of a gear shaft, a bearing, a double-end piston gear rod, an oil cylinder sleeve and a machine case. The double-end piston gear rod is driven by a hydraulic oil cylinder to push the gear shaft to rotate, and the gear shaft drives the scraper rod to rotate through a slider. Asmall gear shaft is connected with an encoder so that angle position signals required when a scraper, an air knife, a material pushing plate and a material distributing port work can be output, automatic control is realized through programming of an electronic control system, executing is realized through a hydraulic system, and the centrifugal machine is suitable for solid-liquid separation of the pharmaceutical and chemical industry.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation equipment in the pharmaceutical and chemical industries, and particularly refers to a vertical scraper unloading mechanism for unloading a filter centrifuge from a center hole of a fixed shaft. Background technique [0002] In the fields of pharmaceutical and chemical manufacturing, solid-liquid separation centrifuges are widely used separation equipment, all of which are named after the discharge method, such as three-legged manual discharge centrifuge, flat plate manual discharge centrifuge, horizontal scraper centrifuge , Vertical scraper pull bag centrifuge, vertical hanging bag centrifuge, flip bag centrifuge, vertical scraper bottom discharge centrifuge, etc. [0003] At present, the domestic pharmaceutical and chemical industries use a large number of low-cost, backward-technical three-legged or flat-plate manual unloading centrifuges, which are labor-intensive and prone to ...

AI Technical Summary

Problems solved by technology

[0003] At present, the domestic pharmaceutical and chemical industries use a large number of low-cost, backward-technical three-legged or flat-plate manual unloading centrifuges, which are labor-intensive and prone to cross-contamination between people and materials, and environmental pollution is difficult to control. Due to the existing automatic Unloading centrifuges such as: vertical scraper centrifuge, horizontal scraper centrifuge, vertical hanging bag centrifuge, flipping bag centrifuge, etc. cannot be replaced without changing the original workshop structure. The improvement of the structure and the installation space of the equipment will inevitably affect the whole body. The modification cost is very high and the transformation period is long, so the old workshop has not been able to change the backward situation of the equipment.
