Drive Control System of Ring Extractor

Abstract

The invention relates to a driving control system of a loop type extractor. The driving control system is characterized in that a loop type chain is jointly driven by an upper driving shaft and a lower driving shaft; the upper and lower driving shafts are driven by an upper hydraulic driving device and a lower hydraulic driving device; the oil inlets of the upper and lower hydraulic driving devices are both connected with a hydraulic oil supply main; the oil return openings of the upper and lower hydraulic driving devices are both connected with the hydraulic oil return main; a hydraulic oil pump is driven by a hydraulic oil pump motor; the median function of a three-position four-way reversing valve is M-type; the suction opening of the hydraulic oil pump is connected with the oil outlet of a hydraulic oil tank and an oil suction filter is mounted at the oil outlet of the hydraulic oil tank; the outlet of the hydraulic oil pump is connected with the port P of the three-position four-way reversing valve; the port T of the three-position four-way reversing valve is connected with the oil return opening of the hydraulic oil tank; the port A of the three-position four-way reversing valve is connected with the hydraulic oil supply main; and the port B of the three-position four-way reversing valve is connected with the hydraulic oil return main. By adoption of the driving control system, double-shaft driving of the loop type chain and synchronized stable running of the two driving shafts can be realized.

Description

technical field [0001] The invention relates to an extractor, in particular to a drive control system for an annular extractor, and belongs to the technical field of vegetable oil extraction control. Background technique [0002] Leaching is the most critical process in the oil refining process. Its principle is to use the mutual solubility of oil and solvent. The solvent penetrates into the solid oil and dissolves the oil to form a thick miscella. Due to the concentration difference, the thick miscella inside the solid oil diffuses to the outside. In the dilute mixed oil, extract the fat. The main equipment in the leaching process is the extractor. According to the material characteristics and output, tank group extractors, horizontal rotary extractors or ring extractors are generally used. [0003] The traditional ring extractor includes a ring chain, the lower end of the head of the ring chain is driven by a single drive shaft, the upper end of the head is turned by an a...

Problems solved by technology

[0004] When driven by a single drive shaft, the meshing point between the sprocket and the chain has high stress and heavy wear; the chain is subjected to tension and bending moment at the same time, the stress is large, and the chain breaks sometimes. Frequent inspection and replacement lead to high operating costs

If dual drive shafts are used, the synchronization problem must be solved. At the same time, if the material level is too high, the extractor will be blocked. leakage
