Whether the first group of sensors 17 and the second group of sensors can detect the distance between the sensor and the slag truck 6 and whether there is a slag truck 6 in front of the sensor, the first group of sensors 17 and the second group of sensors can send the detected results To the control unit, after the first group of sensors 17 and the second group of sensors are set in this way, not only can it be judged whether the slag truck 6 is parked in a predetermined area, but also the length, width and height of the slag truck 6 can be further judged The size and load capacity of the slag truck 6 are used to set the unloading capacity of the blast furnace water slag automatic slag removal method to the slag truck 6 .

In addition, the control system also includes a prompt unit, which is connected to the control unit. The prompt unit includes a speaker and a display. The prompt unit can prompt the driver of the slag truck 6 through various means such as voice, text, and animation. Parked in the predetermined area, and whether unloading has been completed. The prompting unit can also prompt the driver how to move the vehicle to arrive at the predetermined area as soon as possible when the slag truck 6 is not parked in the predetermined area.

A kind of blast furnace slag automatic slag removal method is introduced below. The blast furnace slag automatic slag removal method adopts the blast furnace slag automatic slag removal system. The blast furnace slag automatic slag removal method includes the following steps:

Step 1. The control system judges whether the slag truck 6 is parked in the predetermined area, and when the slag truck 6 stops in the predetermined area, proceed to the next step; when the slag truck 6 is not parked in the predetermined area, remind the driver Move the slag truck 6 to the predetermined area. For example, the length, width and height information of the slag truck 6 that may be pulled and transported can be input into the control unit in advance, and the first group of sensors 17 and the second group of sensors are based on the distance between the sensor and the slag truck 6 and the distance in front of the sensor. Whether there is a data signal of the slag truck 6 is sent to the control unit, and the control unit calculates the current position, external dimensions and load capacity of the slag truck 6 based on the signal, and then judges whether the slag truck 6 stops at the predetermined position. In the area, when the slag truck 6 is parked in the predetermined area, the prompt unit will prompt the driver to proceed to the next step; when the slag truck 6 is not parked in the predetermined area, the prompt unit will remind the driver to move the slag truck 6 to within the predetermined area.

Step 2. The control unit sends a start signal to the automatic slag extractor 4 on the pool and the slag transport equipment 5 on the pool side. The automatic slag extractor 4 on the pool and the slag transport equipment 5 on the pool side work and unload the blast furnace slag into the slag transport truck 6. When the unloading weight of the blast furnace slag reaches the set value, stop unloading (that is, the control unit sends a signal to stop working to the automatic slag extractor 4 on the pool and the slag transporting equipment 5 on the pool side). Specifically, while the automatic slag extractor 4 on the pool and the slag transport equipment 5 on the pool side are working, the belt electronic scale 13 sends the real-time detected slag weight signal that has been transported by the slag transport belt machine 12 to the control unit. When the weight of water slag in the water corresponds to the load capacity of the slag transporter 6, the control unit sends a signal to the automatic slag extractor 4 on the pool and the slag transport equipment 5 on the pool side, so that the automatic slag extractor 4 on the pool and the slag transport equipment 5 on the pool side According to the set program, it will automatically stop and complete the operation of slag extraction and slag transportation. Assuming that the loading capacity of the slag truck 6 is 40 tons, when the belt electronic scale 13 installed in the slag transportation system on the side of the pool detects that 40 tons of slag particles have been unloaded into the slag truck 6, it will send a signal to the PLC control system, fully automatic The slag extraction system stops automatically, and the slag extraction operation ends. Then, the prompting unit reminds the driver that the slag truck 6 can be driven away after loading.

Under the action of various sensors and PLC control system, the automatic slag extraction system for blast furnace slag can continuously carry out slag extraction operations in the slag pool without special personnel on duty, and unload the slag particles from the bottom of the slag pool 2 into the slag truck . In terms of power, the total power of the traditional bridge grab crane is about 205kW, and the total power of the fully automatic slag removal system is 130kW, which is only 63% of the power of the original bridge grab crane; Because the bucket crane is a single-stroke intermittent operation, its working capacity is about 150t/h, while the automatic slag extraction system can realize uninterrupted continuous operation, and its working capacity can reach 300t/h. Generally speaking, the operation cost of the automatic slag removal system is low, and about 60% of electricity can be saved. The blast furnace water slag automatic slag removal system unloads the slag transport truck through a fixed unloading point, which can avoid the problem of slag particle scattering caused by improper manual operation of the grab crane.

In addition, for the slag pool with good filtering effect, since the slag flushing water is fully filtered, the water content in the slag is only about 13%, which is similar to the state of wet sand, and the chain bucket mechanism 8 can use the ordinary chain bucket 18; For poor slag tanks, if the slag contains a lot of water, holes can be opened on the chain bucket and processed into an open-hole chain bucket 19, and the water slag is fully filtered during the process of lifting the water slag upwards by the chain bucket, and then passed through the on-board belt machine, pool, etc. The side slag transport system is unloaded into the slag transport truck, as shown in Figure 4 and Figure 5.

The sedimentation and filtration slag process will generate a large amount of sulfur-containing steam during the slag flushing process. Therefore, the slag pool 2 can be fully enclosed in an environmentally friendly manner during slag flushing as required, which plays a key role in reducing pollution of the slag system. For example, the blast furnace water slag automatic slag removal system also includes a protective cover that can automatically fully seal the slag pool 2. The protective cover is arranged on the upper end of the slag pool 2. The material of the protective cover can be metal or non-metal. The protective cover is connected with the control system. Since the automatic slag removal system can realize unattended operation, after the protective cover is connected with the control system, the entire slag pool (or the entire blast furnace can also be removed) The water slag automatic slag extraction system) is all closed, and only the entrance and exit of the slag transport vehicle 6 are reserved. An exhaust pipe with a power mechanism is arranged on the protective cover to lead out harmful gas (sulphur-containing steam) for treatment. In this way, harmful gases in the slag pool 2 can be avoided from being directly discharged into the air to cause environmental pollution.

The fully automatic slag removal method for blast furnace water slag in the present invention can run automatically according to the preset program, does not need special personnel to be on duty, and has a high degree of automation; the system is capable of continuous operation, not only can save a lot of electricity, but also can avoid manual slag grabbing The dead angle of the filter material is slowed down, the service life of the filter material in the slag pool is greatly improved, and the replacement cost of the filter material is reduced, and the operating cost is low; the system can coexist with the original manual crane slag grabbing system, which is convenient for modification and has high flexibility ; The system unloads slag trucks through fixed unloading points, avoiding the problem of water slag spreading caused by improper manual operation; when necessary, the entire slag pool can be fully enclosed in an environmentally friendly manner, which plays a significant role in reducing the pollution of the water slag system It plays a key role and can bring obvious social benefits.

The above is only a specific embodiment of the present invention, and cannot limit the scope of the invention, so the replacement of its equivalent components, or the equivalent changes and modifications made according to the patent protection scope of the present invention, should still fall within the scope of this patent. category.
