Description

Technical Field

[0002] The tank cleaning gun is used for mechanical cleaning of large crude oil storage tanks. It can perform high-pressure automatic cleaning and is a fully enclosed, physical cleaning technology. It uses a water jet cleaning machine to spray the cleaning medium onto the surface to be cleaned at a certain temperature, pressure and flow rate to remove condensate and sludge, and then recycle it.

[0003] Most of the existing tank cleaning guns are driven by a driving structure that simultaneously transmits rotational power to the gears that control the cleaning machine to rotate horizontally and the gears that control the cleaning machine to rotate vertically. This transmission method has the following disadvantages: the horizontally transmitted rotating gear and the vertically transmitted rotating gear are coupled to each other and have a fixed rotational speed ratio and a fixed rotational direction. The two rotating gears cannot rotate independently. If only horizontal or vertical rotation is required and the other direction does not move, or the speed of a certain rotation direction needs to be changed to be faster or slower, this single-power transmission mechanism cannot be realized, resulting in a single action mode of the cleaning spray gun, which cannot be adjusted independently between the two rotation directions as required, and cannot meet more operational requirements.

The cleaning water will enter the interior of the storage tank from the water inlet pipe 10, the transfer pipe 1 and the water outlet pipe 9 in sequence through water pressure, thereby cleaning the interior of the storage tank.

[0024] During use, the staff starts the first drive motor 11, and the output end of the first drive motor 11 drives the first reciprocating screw 14 to rotate, and the rotation of the first reciprocating screw 14 drives the reciprocating connecting block 15 to reciprocate back and forth on the outer wall of the first reciprocating screw 14; at this time, the first telescopic rod 12 and the first rack 5 will follow the reciprocating connecting block 15 to reciprocate back and forth, and through the engagement of the first rack 5 with the first gear ring 4, the first gear ring 4 can be driven to reciprocate clockwise and counterclockwise inside the first limit bin 2, and then the transfer pipe 1 can be driven to swing left and right; so that the water outlet pipe 9 can swing in a fan shape, thereby increasing the flushing angle of the water outlet end of the water outlet pipe 9 on both sides of the storage tank, thereby improving the tank cleaning efficiency.

At this time, the outer ring of the waterproof bearing 6 will reciprocate with the second gear ring 7. Through the reciprocating rotation of the second gear ring 7, the water outlet pipe 9 can be driven to swing up and down. This increases the flushing angle of the outlet end of the water outlet pipe 9 on both upper and lower sides of the storage tank, thereby improving the cleaning efficiency of the storage tank.

[0027] In the present device, the water pipe 9 is driven by the first driving member and the second driving member to swing in a fan shape and up and down, and the water outlet end of the water outlet pipe 9 can cover a wider area in the storage tank, thereby increasing the cleaning range. Due to the increase in the flushing angle, the dead corners and hard-to-reach parts inside the storage tank can be cleaned more effectively, thereby improving the overall cleaning efficiency. The staff only needs to start the first driving motor 11 and the second driving motor 16, and the entire mechanical transmission system can automatically complete the remaining operations, which reduces the workload of the operator and reduces the complexity of the operation.
