The feeding mechanism of the batching equipment is connected with the reactor, and the method of feeding two-speed feeding is adopted. When the weighing feeder stops feeding, part of the material falls into the weighing hopper in free fall in the air. The set value of the weight of the incremental method should be the standard weight value of the material to be formulated minus the drop value. By automatic weighing the bulk material according to the predetermined ratio, the weighing amount of the material can be controlled and the material can be discharged at the same time. When the material is completed, the pointer is moved to the corresponding proximity switch to make the action, and then the next step of material feeding and weighing is carried out, and so on until all the material ratio is complete.
020-34563445Feeding system in the whole system operation process, the temperature in the reaction tank will be controlled within a certain range, in the jacket temperature design temperature sensor for control. For the industrial control computer, the industrial control computer on the variable signal acquisition and output control, realize the industrial control computer and the field reaction kettle communication. Connected through the RS232/485 conversion module to realize the monitoring software, which can be adjusted according to the time required for the complete reaction of the material. Computer and electric control valve composed of reaction tank temperature - jacket temperature serial dosage, the choice of control mode and control algorithm, set value and related parameters set, reaction tank temperature control real-time curve of the display box, so that the proportionality coefficient, on-line debugging, according to the shape of the real-time curve of the temperature in the reaction tank can be intuitively adjusted in time to integral time and differential time to get the full scale.
Screw conveyor according to the material properties to choose the feed screw, powder material properties mainly refers to the density of accumulation, coarseness and fineness, moisture content, fluidity, etc., by the two same direction of rotation and meshing of the screw composition, the screw screw rib is narrow, screw groove is wide, the work of the material along the spiral ∞ zig-zag channel forward transportation. The screw top mouth of one screw scrapes the side of the other screw with stable tangential relative sliding, which can scrape away the material layer on the interface. Through the weighing module, the signal is transmitted to the weighing instrument, which changes the speed of the motor through the frequency converter, thus changing the feeding flow. As the load cell can transmit the change of material in the machine to the weighing instrument, the material flow rate always fluctuates around the set value, and the average feeding flow rate is highly accurate.
The screw conveyor is connected to the reactor in the Feeder feeding mechanism and can transport the materials in the reactor in a uniform and controlled manner. According to the work requirements can be material conveying and inclined conveying. In the production process or process flow, the feeding type weighing double speed feeding method is used. When the weighing feeder stops feeding, a portion of the material falls into the hopper scale in the air in a free-fall manner. The set value of the incremental method of weighing material weight should be the standard weight value of the material to be formulated minus the drop value. Weighing the bulk material by automatic weighing according to the predetermined proportioning value, it is possible to control the weighing of the material and at the same time to be able to unload the material. Unloading adopts the zero position method, when the material is completed, the pointer moves to the corresponding proximity switch to make the action, and then perform the next step of material feeding and weighing, and so on until all the materials are proportioning completed.
