Problems solved by technology

Most of this kind of equipment is imported special equipment, which adopts customized form, and the control mode is relay + mechanical cam control mode. During the use process, there are problems such as aging of electrical components and easy wear of the cam mechanism, and the accuracy and reliability are poor.
In addition, most of the parts of imported equipment are special products, some of which have been discontinued, and it is not easy to repair and replace
[0003] Patent CN 102463070A discloses a reactor feeding device, which can realize material feeding, but does not have explosion-proof characteristics, and the accuracy of material feeding control is not high

Abstract

The invention provides a feeding device driven by an explosion-proof servo motor. The feeding device comprises a feeding device body, a coupler, the explosion-proof servo motor and an explosion-proof control box, wherein the explosion-proof servo motor is controlled by a servo driver to drive a plug cock to intermittently rotate through the coupler, then a valve ball in the plug cock moves downwards under the action of the differential pressure between a catalyst tank and a reactor and the gravity of the valve ball, and repeated material metering and conveying are achieved. According to the feeding device, the explosion-proof servo motor and the driver thereof are adopted as driving control equipment of the material feeding device, therefore, the precise feeding quantity and accurate position control can be achieved, and the control precision is high.

Description

technical field [0001] The invention relates to the technical field of material feeding and servo control, in particular to a feeding device driven by an explosion-proof servo motor. Background technique [0002] For some special materials in chemical plants, such as solid-liquid mixtures with strong viscosity, general-purpose complete sets of equipment that can achieve accurate measurement and control are relatively rare, especially such equipment with explosion-proof functions are not provided by domestic manufacturers. Most of this kind of equipment is imported special equipment, which adopts customized form, and the control mode is relay + mechanical cam control mode. During use, there are problems such as aging of electrical components and easy wear of cam mechanism, and the accuracy and reliability are poor. In addition, most of the parts of imported equipment are special products, some of which have been discontinued, making it difficult to maintain and replace them. ...
