For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0033] Please refer to Figure 1 and Figure 2 , Figure 1 is a front view of an embodiment of the powder material storage tank cleaning device of the present application; Figure 2 is a top view of an embodiment of the powder material storage tank cleaning device of the present application. As Figure 1 and Figure 2As shown, the powder material storage tank cleaning device includes four lifting mechanisms 1, four fixed tracks 3, four steel ropes 2 and a cleaning mechanism 4.

[0034] The shape of the storage tank can be cylindrical. The four lifting mechanisms 1 are evenly arranged above the storage tank 5 along the axis of the storage tank 5 through a support or other fixing device. As an example, the lifting mechanism 1 can be a winch or an electric winch. The motor power of the lifting mechanism 1 can be selected according to actual conditions.

[0035] The four fixed tracks 3 are fixed to the inner wall of the storage tank 5 along the height direction of the storage tank 5, and the fixed track 3 can be welded to the inner wall of the storage tank 5 by using a rectangular tube. The four fixed tracks 3 can be evenly arranged around the axis of the storage tank 5. The above-mentioned rectangular tube can be made of any of the following steel materials: Q235 steel, SS400 steel, 20# steel, 45# steel, Q345 steel, 16Mn steel.

[0036] The above-mentioned cleaning mechanism 4 can be arranged concentrically with the storage tank 5, and the outer edge of the cleaning mechanism 4 is slidably connected with the above-mentioned multiple fixed tracks 3. Four steel ropes 2 are also arranged correspondingly between each lifting mechanism 1 and the cleaning mechanism 4. In the working state, the lifting mechanism 1 can pull the cleaning mechanism 4 to slide along the fixed track 3 through the steel rope 2. As an example, the above-mentioned steel rope 2 can include but not limited to one of the following: hemp core wire rope, steel core wire rope, natural fiber core wire rope, synthetic fiber core wire rope. In order to improve the reliability of the cleaning device, the cross-sectional diameter of the steel rope 2 is not less than 14mm.

[0037] In order to improve the cleaning effect, the outer diameter of the cleaning mechanism 4 can be slightly smaller than the inner diameter of the storage tank 5, so that in the assembled state, the distance between the cleaning mechanism 4 and the inner wall of the storage tank 5 can be less than 10mm. By controlling the above-mentioned distance, the cleaning efficiency of the cleaning mechanism 4 can be improved.

[0038] The clearing mechanism 4 can be formed by bending a V-shaped steel, the thickness of the V-shaped steel can be greater than 5mm, and the width can be greater than 100mm. The V-shaped angle of the V-shaped steel is inwardly arranged, so that the vertical height of the V-shaped steel is 30-70mm. That is, in the assembled state, the upper wing plate of the V-shaped steel is inclined downward, so that the upper wing plate can form a slide during the clearing process, so that the accumulated powdery material slides downward along the upper wing plate, thereby improving the flow of the powdery material during the clearing process. The flow of the powdery material is also improved, and the clearing efficiency is also improved. Specifically, the above-mentioned V-shaped steel can be made of any one of the following materials: 65 manganese, manganese 18 chromium 2, manganese 13, manganese 16, manganese 13 chromium 2. Or use high-quality carbon steel, such as: 50 manganese, 45 manganese, 40 manganese, 35 manganese, 30 manganese, 25 manganese, 20 manganese (20Mn-50Mn) / 10 steel, 20 steel, 25 steel, 30 steel, 35 steel, 40 steel, 45 steel, 50 steel, 60 steel, 65 steel, 70 steel, 80 steel, etc.

[0039] A plurality of grooves can be formed on the open ends of the upper and lower wing plates of the V-shaped steel, and the plurality of grooves are slidably connected to the plurality of fixed tracks 3 one by one. In this way, the fixed track 3 can not only limit the sliding direction of the clearing mechanism 4, but also will not limit the distance between the clearing mechanism 4 and the inner wall of the storage tank 5.

[0040] The clearing device has been tested in a storage tank storing powdery material with a particle size of less than 1mm and a dense ratio of less than 2, and has good clearing effect.

[0041] It should be noted that although the above is described by taking four lifting mechanisms 1, four fixed tracks 3 and four steel ropes 2 as an example, but this is not the only one, and those skilled in the art can adjust the above-mentioned number according to the actual situation, but such changes do not exceed the protection scope of the present disclosure.

[0042] The clearing mechanism 4 of the utility model is bent by V-shaped steel, and the V-shaped angle is inwardly arranged, so that the upper wing plate is inclined downward, and the upper wing plate can form a slide during the clearing process, so that the accumulated powdery material slides downward along the upper wing plate, thereby improving the flow of the powdery material during the clearing process. The flow of the powdery material is also improved, and the clearing efficiency is also improved.

[0043] Further, the clearing device can further include a controller in communication with the above-mentioned lifting mechanism 1, and the controller can be a PLC (Programmable Logic Controller, Programmable Logic Controller). The above-mentioned controller can start the lifting mechanism 1 periodically, and pull the clearing mechanism 4 to remove the powdery material accumulated on the inner wall of the storage tank 5, thereby realizing the automation performance of the clearing device.

[0044] Finally, it should be noted that: the above embodiments are used to illustrate the technical solutions of the present application, but not limited to them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
