Description

Technical Field

[0001] The utility model relates to the technical field of aviation fuel storage tanks, in particular to a device for sucking residual water from cleaning in aviation fuel storage tanks. Background Art

[0002] Aviation fuel tanks are important equipment used to store aviation kerosene. Since aviation kerosene is directly added to aircraft for use, the purity of the fuel is extremely high, especially the water content must be strictly controlled. For this reason, aviation fuel tanks are usually designed with a conical bottom to facilitate the precipitation and concentration of water and impurities. A sump is set at the center of the cone bottom to collect and remove sediment and water.

[0003] After cleaning the aviation fuel tank and removing the cleaning water, a certain amount of residual water often remains in the sump. If this residual water is not completely removed, it will have an adverse effect on the quality of the subsequent stored aviation fuel and may even cause significant economic losses. Currently, removing this residual water usually requires workers to enter the tank for manual cleaning, a process that is not only inefficient but also increases the labor intensity of workers.

[0004] There is currently a lack of an effective device on the market specifically for removing residual water from aviation fuel storage tanks, which means that workers must use simple tools such as ladles and buckets to manually clean the residual water in the sump. This method is not only time-consuming, but also increases the workload of workers. Similarly, horizontal oil tanks and tank tank trucks also face the challenge of difficulty in completely discharging residual water after the cleaning and suction process due to their curved bottom design. Therefore, there is an urgent need for a residual water suction device that can both improve efficiency and reduce labor intensity to solve this problem. Summary of the invention

[0005] The utility model aims to provide a device for sucking residual cleaning water in an aviation fuel storage tank, so as to improve the efficiency of sucking residual cleaning water in the aviation fuel storage tank.

[0006] The utility model is realized by the following technical scheme: a device for sucking residual water in a cleaning aviation fuel storage tank, which comprises a counterweight frame, on which at least three leg frames for raising the counterweight frame are provided;

[0007] The counterweight frame is connected with a hose; the length of the hose exceeds the height of the leg frame; the upper part of the counterweight frame is provided with a negative pressure interface communicating with the hose, and the lower end of the hose is provided with an air bubble stone;

[0008] The air stone is provided with a plurality of water absorption holes which are connected with the hose.

[0009] Compared with the previous technology, the beneficial effects of the utility model are:

[0010] 1. The utility model can improve the extraction efficiency of residual water from the aviation fuel tank sump, reduce the labor intensity, and effectively avoid the influence of residual water from tank cleaning on the quality of fuel stored in the aviation fuel tank.

[0011] 2. The staff only needs to lift the utility model and place it in the sump, and then use the negative pressure structure to automatically pump out the remaining cleaning water, thereby reducing the work intensity of the cleaning staff.

[0012] 3. The air stone can ensure that the bottom of the sump is always in contact with the air stone, thereby better absorbing the remaining cleaning water.

[0013] 4. The support feet at the bottom of each leg frame are made of rubber material, so that the leg frame and the counterweight frame as a whole have explosion-proof characteristics, ensuring that the utility model will not generate metal sparks due to impact during movement, and at the same time can prevent the anti-corrosion paint on the inner wall of the aviation fuel storage tank from being scratched.

[0019] The utility model is described in detail below in conjunction with the accompanying drawings, but the protection content of the utility model is not limited to the following:

[0020] like Figures 1 to 4 As shown, a device for sucking residual water from washing in an aviation fuel storage tank comprises a counterweight frame 11, on which at least three leg frames 12 for raising the counterweight frame are arranged;

[0021] The counterweight frame 11 is connected to a hose 14; the length of the hose 14 exceeds the height of the leg frame 12; the upper part of the counterweight frame 11 is provided with a negative pressure interface 15 communicating with the hose 14, and the lower end of the hose 14 is provided with an air stone 16;

[0022] The air stone 16 is made of water-absorbing material, and is provided with a plurality of water-absorbing holes 161 connected to the hose 14. The utility model can improve the efficiency of removing residual water from the aviation fuel storage tank, reduce the labor intensity, and also reduce and avoid the influence of residual water from tank cleaning on the quality of fuel stored in the aviation fuel storage tank.

[0023] The negative pressure interface 15 is generally connected to the negative pressure device through a fire hose to achieve negative pressure absorption. The counterweight frame is made of cast iron material to increase the weight of the utility model and prevent it from slipping during work.

[0024] Generally speaking, four leg frames 12 can be configured and distributed in a circular array, and the negative pressure interface 15 is generally located at the center of the counterweight frame 11.

[0025] The cleaning workers can reduce their workload by only needing to lift the utility model and place it in the center of the sump, and then turning on the negative pressure device to automatically pump out the remaining water.

[0026] The support legs 13 at the bottom of each leg frame 12 are made of rubber, so that the leg frame 12 and the counterweight frame as a whole have explosion-proof characteristics. The support legs 13 made of flexible materials combined with the counterweight block can increase the friction between the support legs 13 and the inner wall surface of the aviation fuel storage tank, preventing the utility model from sliding during the suction process. At the same time, it ensures that the utility model will not generate metal sparks due to impact during the movement process. In addition, it can also prevent the anti-corrosion paint on the inner wall of the aviation fuel storage tank from being scratched.

[0027] The leg frame 12 is made of copper, and the corresponding counterweight frame 11 is also made of copper.

[0028] The counterweight frame 11 is also provided with a handle 17, which is convenient for cleaning workers to transfer the utility model.

[0029] In the method of use, the cleaning worker enters the aviation fuel storage tank with the utility model connected with the negative pressure device, turns on the light and uses the handle 17 to lift the utility model and transfer it to the sump. Due to the deadweight of the air stone 16, it can automatically fall into the center of the sump, and cooperate with the negative pressure device to suck away the remaining water in the pit structure. After confirming that the remaining water has been pumped out, the cleaning worker can leave the aviation fuel storage tank.

[0030] Similarly, the horizontal oil tank and tank tanker truck of the aviation fuel can also use the utility model to remove residual water after cleaning.

[0031] Although the utility model uses specific embodiments and their alternatives to illustrate and describe the utility model, it should be understood that various changes and modifications can be implemented as long as they do not deviate from the spirit and scope of the utility model. Therefore, it should be understood that except for the limitations of the attached claims and their equivalents, the utility model is not limited in any sense.
