Description
Technical Field
[0001] The utility model relates to the technical field of coal bunker material dropping, in particular to a signal plastic sheet that prompts a raw coal bunker material dropping opening to be full of coal. Background Art
[0002] Coal is mainly composed of elements such as carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus. The sum of carbon, hydrogen and oxygen accounts for more than 95% of organic matter. It is a very important energy source and an important raw material for the metallurgical and chemical industries. It is classified into lignite, bituminous coal, anthracite and semi-anthracite. The so-called coal bunker refers to a place for temporary storage of coal at the bottom of a coal mine.
[0003] At present, there are two main ways for thermal power plants to remind that the raw coal bunker discharge port is about to be full of coal: one is through the high coal level alarm, and the other is through animation simulation. The shortcomings and deficiencies are as follows: (1) The high coal level alarm and animation simulation are both electronic signals, which are prone to failure and have low stability in complex on-site environments; (2) The high coal level alarm and animation simulation can only provide a rough symbol of the discharge port being full of coal, and the accuracy is not high; the uncertainty and instability of the signal increase the difficulty of the central control operator, resulting in coal overflow at the discharge port, which requires manual cleaning and increases the workload of the belt operator. Therefore, it is urgent to design a signal plastic sheet to remind that the raw coal bunker discharge port is about to be full of coal to solve the above problems. Utility Model Content
[0004] The purpose of the utility model is to provide a signal plastic sheet that prompts that the raw coal bin discharge port is about to be full of coal, so as to solve the problem mentioned in the above background technology that there are currently two main ways for thermal power plants to prompt that the raw coal bin discharge port is about to be full of coal, one is through the high coal level alarm method, and the other is through the animation simulation method. The shortcomings and deficiencies are as follows: (1) The high coal level alarm and animation simulation are both electronic signals, which are prone to failure and have low stability in complex field environments; (2) The high coal level alarm and animation simulation can only provide a rough symbol of the discharge port being full of coal, and the accuracy is not high; the uncertainty and instability of the signal increase the difficulty of operation for the centralized controller, resulting in coal overflow from the discharge port, which requires manual cleaning and increases the workload of the belt attendant.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a signal plastic sheet for prompting that the raw coal bunker discharge port is about to be full of coal, comprising a coal bunker body, a ventilation frame is arranged at the inner center of the coal bunker body, and a flow inclined frame is arranged on the side of the ventilation frame;
[0006] A top frame is fixedly connected to the top of the coal bunker body, an inner wall of the top frame is fixedly connected to a mounting frame, and an inner wall of the mounting frame is provided with a plastic cloth body.
[0007] Preferably, an inner plastic ring is provided on the inner wall of the installation frame, and an outer plastic frame is provided on the outer surface of the installation frame.
[0008] Preferably, fixing bolts are provided at four corners of the surface of the outer plastic frame, and a mounting groove is provided inside the mounting frame.
[0009] Preferably, a connecting rubber ring is provided on the top of the ventilation frame, and ventilation holes are evenly provided on the side walls of the ventilation frame.
[0010] Preferably, a material discharge cone frame is fixedly connected to the bottom end of the coal bunker body, and a material discharge valve seat is fixedly connected to the bottom end of the material discharge cone frame.
[0011] Preferably, the plastic sheet body is adapted to the ventilation frame.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] The signal plastic sheet that prompts that the raw coal bin discharge port is about to be full of coal can enable the equipment to perform more efficient full coal alarm prompt operation through the coal bin body, top frame, mounting frame, plastic sheet body, inner plastic ring, outer plastic frame and fixing bolts. In actual use, the staff can position the entire plastic sheet body inside the mounting groove of the mounting frame through the outer plastic frame on the outer surface, and then perform limit fixing operation through the fixing bolts at the four corners of the surface of the mounting frame. After that, the coal plow can be placed inside the coal bin body to carry out coal loading operations inside the coal bin body. The plastic sheet body is mainly used at the discharge port of the raw coal bin of the coal transportation system of a thermal power plant. When the discharge port of the raw coal bin is about to be full, the signal plastic sheet is blown up by the return air pressure, which is used to intuitively prompt that the discharge port is about to be full of coal, so that the control operator can lift the coal plow in time to prevent coal overflow, ultimately achieving the effect of reducing the workload of personnel, reflecting the practicality of the equipment design.
[0014] The signal plastic sheet that prompts that the raw coal bin discharge port is about to be full of coal further improves the overall use effect of the equipment through the coal bin body, mounting frame, plastic sheet body, connecting rubber ring, vent, discharge cone frame and discharge valve seat. In daily use, the staff can adaptably install the ventilation frame as a whole in the inner center position of the coal bin body. When the coal is then transported into the coal bin body through the coal plow, it can be evenly transported downward from the flow inclined frame structure on the side of the ventilation frame. When the raw coal bin discharge port is about to be full of coal, a space with only one air outlet at the discharge port will be formed, the coal level continues to rise, and the compressed air is discharged from the discharge port. At this time, the airflow will blow up the plastic sheet body, thereby ensuring that the plastic sheet body as a whole can complete the inflation alarm prompt operation more efficiently and accurately, reflecting the comprehensiveness of the equipment design.
