High Output Automatic Dry Mortar Mixing Plant With Centralized Control System

Dry mortar mixing plant with high output dry mortar production line

Description:

The main equipment of the dry mortar production line is divided into six parts: control system, mixing system, drying system, weighing system, packaging system, dust removal system. The dry mortar is mainly composed of cement, dry sand, fly ash, thickened powder and other raw materials. The special process mortar also needs to add a small amount of additives such as cellulose ether, which are stored in the storage tank for production and use. The wet sand is first sent to the screening machine through a conveyor for screening, and then dried by a conveyor in a three-pass dryer that is sent to the drying line. In the raw material configuration, in the mortar production process, the yellow sand, cement, fly ash and admixture stored in the storage tank are weighed and fed into the mixing mixer according to a certain proportion, and the mechanical mixing of the fully dry mortar is mechanically mixed into the building ground masonry mortar. Finished mortars such as plaster and floor mortar. After being packed or in bulk, it is transported to the use site for construction by dry special mortar. According to the production capacity of the factory, the scale of the dry mortar production line is between 10 and 150,000 tons. The production line in production is based on the layout of dry mortar equipment, which is divided into tower type and two-stage type. The tower-style layout material flow is smooth, the floor space is small, but the structural cost is too large, the two-stage layout is increased twice, and the storage bin is mainly based on the ground.

Technical Data:

Automation system features:

1. In the central control room, the computer is used to monitor the production site. The Chinese menu and graphic display are used. The screen displays the status of each raw material storage tank, the status of each pipeline, the status of the valve, and the condition of the storage tank and the liquid pipeline. The weight of the ingredients is dynamically displayed, and the state of the entire ingredient line can be clearly seen on the screen of the industrial computer. The programmable logic controller and the industrial computer use fiber-optic Ethernet hybrid communication to transmit data, realizing high-speed and reliable data transmission.
2. Recipe management: After establishing and storing the recipe on the computer, the staff selects the product formula to be produced, presses the start batching button, and the system automatically and orderly takes the required raw materials from the raw material storage tank to the target position, and waits until The initial integration is automatically transferred to the finished product tank.
3. Automatic conveying: the raw material is first transported by the screw conveyor to the measuring silo. When the weight of the raw material reaches the set weight, the screw conveyor stops feeding, and then the metered material is sent to the target position through mechanical or pneumatic conveying. .
4. Error correction and alarm; when the system accidentally fails, it can automatically take the corresponding steps or measures (such as displaying recommended measures on the monitor, alarm, pause, request manual intervention, emergency stop, etc.), and indicate the type of fault and fault Location and other information. When in the batching process, if the error value is greater than the allowable value due to accidental and special reasons, the ingredient batching system outputs an alarm signal to automatically stop the material. The previous process can then be continued by manually calibrating the error.
5. Operation authority: On the industrial computer side, different operation rights can be set according to the level of different departments and different operators, the level of authority can be programmed, and the password can be set.
6. Production data management; the system automatically records the data in the production process and outputs it in the form of a report. The management personnel can understand the configuration data of each batch through the report, such as adding the actual weight of each raw material, adding time, etc. Wait. The system is reliable and meets the requirements of 24 hours of continuous operation. Various mechanisms such as feeding and weighing are designed in accordance with convenient maintenance and repair to meet the user's maintenance and simple repair requirements for the system in use.

Advantages of automatic dry mortar production line:

The automated production management system can realize the transformation of the field operation mode from raw material storage, material measurement, batching to discharge. It uses computer network communication, material bar code and PLC control technology to achieve accurate weighing of materials through centralized control of production formulas, and guides workers to configure production according to the standard operating procedures (SOP) specifications. Complete the electronicization of the batch operation record of the workshop and the transparency of the batch production implementation progress.
