Abstract

The invention relates to the field of automatic control and discloses an electrodeless control device for blanking. According to the electrodeless control device, the technical problem that the blanking quantity cannot be accurately controlled in a blanking process in the prior art is solved. The electrodeless control device comprises a finished product bin, a charge level indicator, a gate, a dry stream weighing chamber, a flow meter, a liquid spraying nozzle and a controller, wherein the finished product bin is used for storing materials; the charge level indicator is arranged on the finished product bin and is used for measuring the positions of the materials; the gate is arranged at a blanking hole of the finished product bin; the dry stream weighing chamber is arranged at the bottom of the gate; the flow meter is arranged in the dry stream weighing chamber and is used for detecting the flow of the materials in the dry stream weighing chamber; the liquid spraying nozzle is fixed at the dry stream weighing chamber and is used for mixing liquid with the materials in the dry stream weighing chamber; the controller is connected with the charge level indicator, the gate and the flow meter and is used for regulating the blanking quality of the gate and the liquid flow of the liquid spraying nozzle according to the flow or the positions of the materials and closing the gate when the electrodeless control device is in a power off condition. According to the electrodeless control device, the technical effect for accurately controlling the blanking quantity of the gate is achieved.

Description

Technical field [0001] The invention relates to the field of automatic control, in particular to a non-polar control device for feeding. Background technique [0002] In the process of feed processing, it is necessary to add a small amount of liquid to the feed according to the proportion, and in order to accurately control the proportion, it is necessary to control the flow of the finished material when adding a small amount of liquid to the feed, usually, powder or granule The material is not easy to quantitatively control during the blanking process. [0003] At present, industrial granular or powdery materials generally adopt manual control or electric control according to actual needs. Manual methods cannot adjust the gate opening according to the flow in time, and electric control makes the gate opening control not precise enough; in addition, electric control After the power failure, the gate cannot be automatically closed in time, causing the material to continue to be cut...
