Description

Technical Field

[0001] The utility model relates to the technical field of vibration and blockage clearing equipment, in particular to a system for vibration and blockage clearing of coal conveying equipment through a double-delay time relay. Background Art

[0002] The feed blockage of fine powder grinding is often caused by the material, not the particle size of the material, but the material entry speed. However, we know that the particle size of the material can be controlled manually. Although the material speed can also be controlled manually, people are not machines after all. It is impossible to make the feed exactly the same every time, so it is inevitable that the feed will be uneven, and then cause material blockage, so that the machine cannot operate normally, that is, a vibrator is needed to clear the blockage.

[0003] In addition, the coal slime is mixed with the coal transportation system, which makes it easy for coal to be blocked at the fine screen and fine crusher. The fine material is transmitted through the transfer pipeline at the fine screen and fine crusher. Since the vibrator is not designed during the infrastructure construction, it does not have the conditions for adding remote start. Therefore, each start and stop work can only be operated by the operating staff on duty at the fine screen layer from the local control cabinet. On the one hand, this leads to a waste of a lot of manpower. In the current operating environment of the coal transportation system, the equipment defects increase, which increases the workload of the operating personnel. There is also the risk of insufficient lighting when operating at the fine screen at night, which may cause unsafe incidents. On the other hand, since the operating personnel do not operate the vibrator frequently enough, the vibration effect is not obvious. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0017] Embodiment 1

[0018] See also Figures 1-2In the embodiment of the utility model, a double-delay time relay coal conveying rapping system includes a double-delay time relay 1 and a rapper 4. The power supply part of the double-delay time relay 1 is connected to the on-site cable through the first wire 3 and the second wire 2 to energize. The delay control part 5 of the double-delay time relay 1 is electrically connected to the rapper 4. According to the requirements of the on-site equipment operation mode, a rectification plan is proposed, and finally a DH48S-SAC220V double-delay time relay 1 is selected as the starting element of the rapper 4. The on-site drawings are designed according to the working principle of the double-delay time relay 1. Since the rapper 4 needs to be started after the fine screen is put into operation, a pair of normally open points are taken on the auxiliary contacts of the contactor of the fifth axis motor of the fine screen as the starting instructions of the rapper 4. The contacts are connected to At the terminal of the double delay time relay 1 in the control cabinet of the vibrator 4, when the fine screening machine is running, the normally open point is closed to provide power to the double delay time relay 1, and the contacts of the double delay time relay 1 are used to control the start and stop of the vibrator. After the modification of the vibrator 4 control system of the fine screening machine transfer pipeline, the equipment start and stop time can be flexibly set according to the operation conditions of the on-site equipment. For example, the time can be set to 10 minutes to start the equipment for 8 seconds, and there is no need for operating personnel to frequently go to the site for operation, saving a lot of manpower. It is an intelligent design and provides reference experience for the modification of other equipment. The equipment works according to the scheduled time, which improves the working effect of the vibrating, can greatly alleviate the coal blockage at the fine screening machine, and reduce the frequency of maintenance personnel entering the equipment to clean up the accumulated coal, thereby reducing safety risks.

[0019] In a preferred embodiment, the rapper 4 is arranged on the transfer pipeline, and the circuit of the rapper 4 is controlled by the double-delay time relay 1 to perform cyclic delayed beating. Directly vibrating the fine screen machine may cause deformation or damage to the life of the fine screen machine. Therefore, the output end of the fine screen machine is directly replaced with the transfer pipeline, and a flexible connection is adopted to avoid damage to the equipment due to vibration.

[0020] In a preferred embodiment, the reset part 6 circuit of the dual-delay time relay 1 is controlled by the single-chip microcomputer control terminal 8, and the single-chip microcomputer control terminal 8 controls the motor operation of the vibrator 4 through the motor driver 9. The dual-delay time relay 1 and the single-chip microcomputer control terminal 8 are both prior arts and are not described here in detail.

[0021] Embodiment 2

[0022] In the embodiment of the utility model, a weighing sensor 7 capable of weighing the transit pipeline is also provided on the transit pipeline. The weighing sensor 7 transmits an electrical signal to the single-chip control terminal 8. When a blockage occurs, material will pile up in the transit pipeline, causing the weight of the transit pipeline to increase. Delayed vibration cannot guarantee that the pipeline can be cleared at the right time for each vibration, nor can it be determined whether to vibrate according to the blockage situation. It is not smart enough. Therefore, a weighing sensor 7 capable of monitoring the weight of the transit pipeline is installed on the transit pipeline.

[0023] In a preferred embodiment, the single-chip microcomputer control end 8 controls the operation of the motor of the vibrator 4 through the motor driver 9, and resets the delayed opening or delayed closing time of the double-delay time relay 1 by controlling the reset part 6 of the double-delay time relay 1. A weighing sensor 7 capable of monitoring the weight of the transit pipeline is installed on the transit pipeline. When the transit pipeline is blocked, the weight increases, and the single-chip microcomputer control end 8 sets the peak value and the valley value. When the weighing sensor 7 measures that the weight of the transit pipeline reaches the peak value, the single-chip microcomputer control end 8 controls the motor driver 9 to drive the vibrator 4 to operate. After dredging, the weight of the transit pipeline decreases. When it reaches the valley value set by the single-chip microcomputer control end 8, the single-chip microcomputer control end 8 controls the motor driver 9 to stop the vibrator 4 from operating, and synchronizes the timing time of the double-delay time relay 1.

[0024] It should be noted that the above embodiments all belong to the same utility model concept, and the description of each embodiment has its own focus. For matters that are not described in detail in some embodiments, reference can be made to the description in other embodiments.
