High-accuracy intelligent electric control system of dry mix mortar production line

Abstract

The invention relates to a high-accuracy intelligent electric control system of a dry mix mortar production line. The system is composed of a powder distribution system, a sand distribution system, a weighing system, a mixing agitator, a dust collecting system and a finished product assembling system. Due to the fact that the powder distribution system in the system is connected with a thermorelay, a contactor and a frequency converter, the problem that in the traditional method, it is difficult to control the material accuracy is solved, and meanwhile the running condition of a motor on site can be monitored; by means of the arrangement of the dust collecting system, the dust pollution in the production process of dry mix mortar is greatly reduced, meanwhile, according to the dust collecting system, by adopting the control mode that a motor protector is connected with the contactor, the current can be adjusted, the space of an electric control cabinet is saved, the control mode of soft start is adopted by the mixing agitator, the starting mode of the mixing agitator is changed into soft start, trip is prevented on account of overcurrent when the mixing agitator starts, and the problem that hardware is prone to damage when a traditional tri-star start mode starts frequently is solved.

Description

technical field [0001] The invention relates to the field of mortar production, in particular to an intelligent electrical control system for a high-precision dry-mixed mortar production line. Background technique [0002] There are many types of dry powder sand products, each of which requires different raw materials and production processes, and the difference in product density will also lead to differences in production methods. At present, most of the intelligent electrical control systems of the dry-mixed mortar production line are weak in monitoring the accuracy of material batching. In terms of material weighing system control, the air switch is connected to the contactor. The air switch will trip during operation, but the contactor is still closed. Therefore, this control method must also add a protection monitoring device to the air switch, which consumes a lot of space inside the electric control cabinet. In addition, the existing intelligent electrical control s...

Problems solved by technology

At present, most of the intelligent electrical control systems of the dry-mixed mortar production line are weak in monitoring the accuracy of material batching. In terms of material weighing system control, the air switch is connected to the contactor. The air switch will trip during operation, but the contactor is still closed. Therefore, this control method must also add a protection monitoring device to the air switch, which consumes a lot of space inside the electric control cabinet.

In addition, the intelligent electrical control system of the existing dry-mixed mortar production line adopts the star-delta control mode to control the mixing mixer. There are many connections, and frequent startups will cause hardware losses, and the actual situation of the motor cannot be well monitored.
