Description

Technical Field

[0001] The utility model relates to the technical field of antifreeze liquid preparation and spraying equipment, in particular to an antifreeze liquid preparation and spraying system. Background Art

[0002] At present, belt conveyors are important equipment for transporting materials in coal mines. During low-temperature operation in winter (for example, in cold areas, when the temperature is below -15°C), the coal will freeze and stick to the conveyor belt, making it impossible to completely remove the coal on the belt at the drop point. Instead, the coal will adhere to the belt, and the frozen and stuck coal will fall randomly during the operation of the belt, and it is easy to form a large amount of fallen coal at different locations where the belt conveyor is located, which not only causes coal waste and environmental pollution, but also easily causes safety accidents and transportation interruptions. At the same time, the freezing of coal during belt transportation will also lead to reduced belt transportation production efficiency, equipment damage, unstable operation and increased belt breakage risks.

[0003] To address the above-mentioned problems, the prior art generally requires the application of antifreeze sticking technology on the surface of the belt to effectively prevent the formation of frozen coal sticking to the conveyor surface. Typically, an antifreeze sticking solution (i.e., antifreeze liquid) is prepared based on an antifreeze sticking material (i.e., antifreeze material), and then the antifreeze sticking solution is sprayed on the belt surface to form an antifreeze sticking layer. For example, a calcium chloride solution is sprayed on the belt surface in conjunction with a sweeper to effectively prevent the formation of frozen coal sticking to the belt surface. However, the current degree of automation in the preparation of antifreeze liquid in coal mines is relatively low, and the preparation of antifreeze liquid is largely manual. In addition, since coal mines consume approximately hundreds of tons of antifreeze sticking material to prepare antifreeze liquid each winter, the entire antifreeze liquid preparation process is labor-intensive, time-consuming, and labor-intensive. The uncontrollable nature of manual operation can also lead to waste of materials such as calcium chloride and inaccurate antifreeze liquid concentration ratios, resulting in wasted resources and poor antifreeze effectiveness. At the same time, the extremely cold winter weather further increases the labor intensity of front-line workers, resulting in poor working conditions, low work efficiency, and the risk of personal injury.

The spray device can take liquid from the liquid storage tank 31 and the stirring chamber 211 through a three-path liquid intake pipeline. The appropriate liquid intake path is selected according to demand and liquid level conditions.

[0071] Step 9: The detection device 90 monitors the running status and freezing condition of the belt conveyor. The air compressor 71 provides compressed air, which is stored in the air storage tank 72 to provide a stable air source for the spraying system and prepare for automatic spraying.

[0072] Step 10: The proportional controller 80 automatically adjusts the working state of the driving pump 150 and the air compressor 71 according to the feedback from the sensor system and the monitoring data of the detection device 90 to control the spraying amount and pressure;

[0073] Step 11: Based on the feedback from the detection device 90, the antifreeze liquid is atomized and evenly sprayed onto the belt conveyor (e.g., the outer belt 110) through the spraying device 60;

[0074] Step 12: After the spraying is completed, the pipeline 50 is purged to remove the residual antifreeze liquid from the nozzle of the spraying device 60 to prevent the nozzle from being blocked, so that the spraying device 60 can maintain a better working condition.

[0075] In summary, the present invention provides an antifreeze preparation and spraying system. The present invention realizes automatic preparation and automatic spraying of antifreeze by arranging a grinding device 10, a stirring device 20, a storage device 30, a main output pipeline 40, a purge pipeline 50, a spraying device 60 and an air conveying device 70 to work together. It can efficiently and accurately prepare antifreeze of a set concentration, and automatically spray it according to environmental parameters to ensure that the antifreeze evenly covers the set position; by arranging the air conveying device 70 to generate compressed air, the compressed air is mixed with the antifreeze in the main output pipeline 40 and sprayed out from the spraying device 60, thereby improving the spraying efficiency and spraying uniformity of the antifreeze, avoiding the occurrence of omissions or unevenness in the manual spraying method, and greatly improving the actual spraying antifreeze effect of the antifreeze preparation and spraying system; when the main output pipeline 40 and the spraying device 60 are disconnected, the antifreeze is automatically sprayed. In the open state, the compressed air in the air conveying device 70 is set to purge the cleaning spraying device 60 through the purge pipe 50, which effectively avoids the clogging of the spraying device 60 after long-term spraying, thereby ensuring the long-term stable spraying operation of the spraying device 60; compared with the existing method of relying on manual antifreeze preparation and spraying, the utility model not only saves time and effort, but also avoids the waste of materials and inaccurate antifreeze concentration ratio caused by the uncontrollability of manual operation, thereby saving resource waste and improving the antifreeze effect; at the same time, it also reduces the labor intensity of front-line workers, improves working conditions and avoids personal injury; the utility model has a simple structure and low cost, is easy to assemble and subsequently maintain, plays an important role in solving the problem of coal freezing and sticking to the belt, ensuring safe production in coal mines and improving transportation efficiency, and is suitable for large-scale promotion and use.
