Description
Technical Field
The utility model relates to the technical field of coal injection pipeline dredging, in particular to a device for automatically dredging a coal injection pipeline.
Background
The coal injection pipeline of the coal injection system has the characteristics of long length, small pipe diameter and more bent pipes, and is easy to be blocked under a special condition. Once the coal dust injection pipeline is blocked, the coal dust injection pipeline needs to be treated in time. In the existing treatment method, coal is generally required to be stopped, then the coal climbs onto a support of an injection pipeline, cleaning wind is started, and coal is discharged through an outer discharge port to be treated. When the blockage is serious and coal dust cannot be discharged, the problem is serious, the coal dust can be treated by a light person for several hours and a heavy person for several days, and the coal injection pipeline is cut more seriously and treated section by section, so that the production is influenced, and the time and the labor are wasted.
The existing method is used for treating the blockage of the coal injection pipeline, the main control industry is connected with on-site inspection staff, the on-site staff carries tools and protection facilities to the pipe gallery to confirm the blockage point, and the reaction speed is low. After confirming the jam position, need open the scavenging wind, open outer discharge port, the long-pending coal of section one by one discharge, the treatment progress is slower, when the jam is serious, can discharge the pipeline only in a few days, seriously influences blast furnace normal production. In the process of treating pipeline blockage, a plurality of persons are required to cooperate, climb to a pipe gallery and keep knocking the vibration pipeline, coal is discharged in an auxiliary mode, high-altitude operation is involved, labor intensity is high, and danger coefficient is high. Therefore, there is an urgent need to design a device for automatically dredging the coal injection pipeline, so as to solve the problem that the existing coal injection pipeline is difficult to clean due to blockage.

Drawings
FIG. 1 is a schematic structural view of an apparatus for automatically dredging coal injection pipes.
In the figure: 1-vibrating a pipeline; 2-a vibration motor; 3-vibrating a pipe support; 4-coal injection pipeline; 5-pulverized coal flowmeter.
Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described in further detail below with reference to the accompanying drawings in the embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, an automatic dredge coal injection pipeline's device, including vibrating pipeline 1, vibrating motor 2, vibrating pipeline support, coal injection pipeline 4 and buggy flowmeter 5, vibrating pipeline 1 passes through flange mount on coal injection pipeline 4, installs vibrating motor 2 on the vibrating pipeline 1, vibrating motor 2 installs in vibrating pipeline 1 bottom, installs vibrating pipeline support 3 on the vibrating pipeline 1, vibrating pipeline support 3 supports fixed vibrating pipeline 1, vibrating motor 2 drives coal injection pipeline 4 whole vibration, shakes the buggy of spreading in the coal injection pipeline 4, dredging pipe.
A coal powder flowmeter 5 is arranged on the coal injection pipeline 4 at the rear part of the vibration pipeline 1. The pulverized coal flowmeter 5 is mounted on the coal injection pipeline 4 through a flange.
The vibration motor 2 is provided with a motor start-stop controller, the motor start-stop controller is connected with the coal powder flowmeter 5 through a communication line, and the coal powder flowmeter 5 measures the coal powder flow and sets the upper flow limit value and the lower flow limit value.
The working principle of the utility model is as follows:
1. when the pulverized coal flow meter 5 shows that the measured flow is normal (i.e., the instantaneous flow is between the flow upper limit value and the flow lower limit value), the motor start-stop controller does not work, and the vibration motor 2 is in a non-action state.
2. When the flow in the pipeline is detected to be reduced by the pulverized coal flow meter 5 (namely, the instantaneous flow is lower than the lower limit value of the flow), the motor start-stop controller starts to work, and the vibration motor 2 is controlled to start.
3. The vibration motor 2 is powered to run, and the vibration device drives the coal injection pipeline 4 to vibrate, so that coal dust vibrates, and the pipeline is restored to be smooth under the pushing of pipeline pressure.
4. When the pulverized coal flow meter 5 detects that the flow in the pipeline is recovered to be normal (namely, the instantaneous flow is between the upper flow limit value and the lower flow limit value), the motor start-stop controller stops working, and the vibration motor 2 is controlled to stop working.
The present utility model is not limited to the above embodiments, and any person who can learn the structural changes made under the teaching of the present utility model can fall within the scope of the present utility model if the present utility model has the same or similar technical solutions.
