Description

Technical Field

[0001] The invention relates to the field of gel spraying, and more specifically to a gel spraying device for preventing and controlling coal spontaneous combustion, retardation and plugging in coal mine goafs. Background Art

[0002] Goafs in coal mines are prone to spontaneous combustion disasters due to air leakage and long oxidation time. In order to ensure the safe production of mines, it is necessary to prevent and control coal spontaneous combustion. At present, coal mines often adopt yellow mud injection, three-phase foam injection, inert gas injection, inhibitor spraying and high molecular weight material pressure injection. Since the inhibitor gel has good physical and chemical inhibitory effect and strong air leakage plugging ability, it is often used for coal spontaneous combustion prevention. Usually, the gel solution is sprayed after the working face advances 100 meters or when there are signs of spontaneous combustion of coal in the goaf. The spraying should be carried out every two cycles to ensure uniform spraying without dead corners. After spraying, the gel solution evenly covers the surface of the coal block, isolates the external oxygen supply, and prevents the oxidation of the coal in the goaf.

[0003] In the prior art, a water pipe is generally fixed to an inhibitor mixing barrel, and the inhibitor solution is prepared by injecting water. After the preparation is completed, an operator holds a spray pipe or fixes the spray pipe above the coal mine goaf to perform fire prevention and extinguishing operations. This method has the problem of uncontrollable concentration of the inhibitor solution.

[0004] Based on the above technical problems, the prior art also provides some solutions. For example, the Chinese patent with the authorization announcement number CN118030162A discloses an intelligent spraying system for inhibitors in coal mine goafs. The device prepares high-concentration saturated solutions and suspensions, and stores high-concentration inhibitor solutions (mass concentration of 50% to 70%) and part of the suspensions in a premixing tank. The solid inhibitor is converted into an inhibitor solution, which can be better accurately measured and intelligently operated. Then, the inhibitor solution in the premixing tank and water are mixed again in a buffer tank to obtain an inhibitor solution (mass concentration of 10% to 20%) that meets the use requirements, thereby solving the problem of uncontrollable concentration of the inhibitor solution in the prior art.

[0005] However, in actual production operations, the fixed spray head limits the spraying range of the gel solution, and the angle of the spray head is difficult to adjust quickly. There are many areas in the goaf that need to be sprayed with gel, and the existing fixed solution side nozzles will result in insufficient coverage. Long-term placement will cause precipitation and stratification in the gel solution, and after a long period of accumulation, the gel will clump. When the gel solution is directly used for spraying, it will cause blockage in the pipeline. The gel solution is easy to form attachments on the inner wall. The precipitation and attachment materials will reduce the amount of gel solution available in the tank, reduce the uniformity of the gel solution, and cause the sprayed gel solution to have different effects, reducing the treatment effect of the gel in the goaf. Summary of the invention

[0006] In view of the problem in the prior art that high temperature will accelerate the chemical reaction of the gel solution, causing changes in its properties and reduced stability, and that the precipitated and attached materials will reduce the amount of gel solution available in the tank, thereby reducing the treatment effect of the gel in the goaf, the purpose of the present invention is to provide a gel spraying device for preventing and controlling coal spontaneous combustion, retardant and leak-proofing in coal mine goafs.

During the rotation of the ventilation fan blades 1108, the air circulation performance on the surface of the gel solution storage tank 2 is improved and wind force is generated. The fast-moving wind force blows toward the surface of the heat sink 1103, which improves the heat dissipation effect of the inner heat-conducting metal ring 1102, thereby quickly cooling the gel solution storage tank 2, reducing the impact of the ambient temperature on the gel solution accumulated in the gel solution storage tank 2 during outdoor work, maintaining the state of the gel solution, and improving the treatment effect.

At the same time, the air circulation performance on the surface of the gel solution storage tank 2 is improved and wind is generated during the rotation of the ventilation fan blades 1108. The fast-moving wind blows toward the surface of the heat sink 1103, which improves the heat dissipation effect of the inner heat-conducting metal ring 1102, thereby quickly cooling the gel solution storage tank 2, reducing the impact of the ambient temperature on the gel solution accumulated in the gel solution storage tank 2 during outdoor work, maintaining the state of the gel solution, and improving the treatment effect.

[0066] During the rotation of the transmission ring seat 1106, the top fixing frame 1109 and the bottom transmission rod 1206 will be driven to rotate. Through the connection of the side sleeve 1207, the rotation of the bottom transmission rod 1206 can drive multiple sol stirring blades 1208 to rotate along the inner side of the gel solution storage tank 2, which can keep the components in the gel solution in a uniformly mixed state, avoid the occurrence of precipitation and stratification, and improve the treatment effect during the spraying process of the gel solution.

[0067] During the rotation of the bottom transmission rod 1206, the bottom connecting frame 1210 will be driven to move synchronously along the inner wall of the gel solution storage tank 2. At the same time, during the rotation, the side cleaning soft brush 1211 will be driven to clean along the inner wall of the gel solution storage tank 2. The gel solution attached to the inner wall of the gel solution storage tank 2 can be scraped off to maintain the uniformity of the gel solution, reduce the growth of microorganisms caused by long-term attachment, and reduce the workload of the operator for subsequent cleaning.
