C750 Feeding system

The feeding system adopts automatic control to realize the automatic control and supervision of raw material feeding, weighing and metering, vacuum feeding, dispersion and mixing processes. The dispersion time and cylinder number can be selected and adjusted on the computer according to the production requirements. The opening and closing of the motor equipment and the opening and closing of the feed valve in the process are controlled by the computer.

The main task of the raw material Feeder is to mix and feed, and on the premise of ensuring the production of material and formula accuracy and system reliability, the use of a larger set of self-developed batching machine in the raw material warehouse, concentrated for all the extruder preparation of the required raw materials. This allows all extruders to share a set of batching machines to reduce system cost and improve equipment utilization, while also eliminating raw material handling. The positive pressure thin phase pneumatic conveying method is used to blow the prepared raw material through the conveying pipe to the hopper of the extruder.

The feeder is mainly composed of two Roots blower units, a total feed pipe and a number of branch feed pipes, two pneumatic branch reversing valves (hereinafter referred to as branch valves) and a number of cyclone separators. One of the two fans is a backup fan, and each Roots blower unit includes a Roots blower, a typhoon electromechanical machine and a fan control cabinet, whose task is to generate compressed air flow required for pneumatic conveying. The fan outlet is connected to one end of the mixing chamber, and the total material delivery pipe is connected to the other end of the mixing chamber. The feeding system and part of the fan unit and the total feeding pipe can be installed in the raw material warehouse. The total feed pipe from the raw material warehouse is connected with an independent branch valve, which can form two branch feed pipes respectively to two workshops. Similarly, n+1 branch feed pipes can be formed with n branch valves, and these branch pipes are equipped with 1 branch valve at the location (hopper) of each extruder in the workshop. When selected to feed to a extrusion machine, the relevant branch valve is played in the corresponding direction, so that the material can only lead to the extrusion machine and can not go to other locations, so that the fan will mix the air mixture in the mixing chamber through the various links of the feeding channel to blow to the corresponding cyclone separator, after separation, the material reaches the corresponding extrusion machine hopper.


Application of liquid pumping and mixing batching system
The batching system adopts dual CPU to form a redundant system, and the STEP7MicroWin V4.0SP6 programming software provided by Siemens is used as the man-machine interface to write debugging programs and download programs. The PC and PLC experimental machine are connected by a PC/PPI cable for communication, and the corresponding parameters are set.
Powder Dosing System Design
The automatic dosage system consists of an industrial grade control computer, programmable controllers, and electrical control boxes, and is designed to meet the needs of a maximum number of silos and platform scales for mixing, weighing, and mixing control.
Application of weighing modules in large storage tanks
Weighing modules can be used as storage and irrigation materials in and out of the warehouse measurement, can also be used for process flow control, in general, according to the shape of the tank and the installation of different ways to choose 3 or 4 weighing modules to complete, especially suitable for chemical plant production process quantitative feeding system occasions to use.
Screw dosage system technology application
Screw automatic dosage system is the ideal equipment for continuous dosage and measurement of bulk materials, which can set high, middle and low feeding, and then control the feeding speed of screw feeder, so as to achieve the purpose of accurate dosage. According to the actual process of batching process, it reflects the operation status of feeding, batching, feeding and related equipment in the form of dynamic screen.
Application Design of Weighing Mixer
Weighing and mixing machine through PLC to control the frequency converter, so that the speed motor drives the metering screw according to the set speed running down the material. The whole weighing and dosing system can be divided into small material weighing, large material weighing and micro material weighing. It adopts the way of uniform speed feeding, and the way of decreasing speed feeding is adopted in the low speed stage.
Automatic Powder Batching System
Batching system in the field of powder processing and treatment, the leading technology of powder processing equipment absorbed and optimized in the weighing and mixing machine in accordance with the production instructions and formulas, a variety of materials will be placed, transported to the set station, using automatic walking weighing mechanism, a variety of materials accurately and proportionally added to the barrel.
Reactor feeding and dosage system realization
Reaction kettle feeding dosage system through the explosion-proof electronic weighbridge direct collection of weight signals, automatic control of weighing, the operator through the keyboard or the mouse in the upper computer human-machine interface (HMI) on the input charging information (charging type, weight, etc.), monitoring the whole process of charging control, printing the results of the charging and production reports, to achieve the process of charging the measurement and control of the integration of the management, is not lost as a practicable and effective method.
