A high-pressure three-dimensional water jet cleaning device for fuel tank

Abstract

The invention provides a high-pressure three-dimensional water-jet oil tank cleaning device. The high-pressure three-dimensional water-jet oil tank cleaning device comprises a cleaning device and a blow-drying device, wherein the cleaning device comprises a clean water tank, the outlet of the clean water tank is connected with a plunger pump inlet through a water outlet pipe, the outlet of the plunger pump is connected with a hydraulic control loop, the outlet of the hydraulic control loop is connected with a high-pressure three-dimensional rotating spray nozzle arranged in an oil tank through a high-pressure water supply pipe; the blow-drying device comprises an air gun and an electromagnetic valve arranged on the air inlet pipe of the air gun, a switch is arranged on the handle of the air gun and the switch is connected with the electromagnetic valve through a control circuit. The device can simultaneously complete the cleaning and blow-drying of the oil tank, foreign matters such as oxide scales, steel balls and welding slags are taken away by using high-pressure water flows, then the oil tank is blow-dried after cleaning is completed, the requirement on the cleanness of the oil tank is satisfied, the water scale caused by residual cleaning solution is reduced, the working conditions of operators are greatly improved and the occupational injuries of the operators are effectively avoided.

Description

technical field [0001] The invention relates to a fuel tank cleaning device, in particular to a high-pressure three-dimensional water jet cleaning fuel tank device. Background technique [0002] The existing method for cleaning the interior of the fuel tank of a forklift is: the frame of the forklift is off-line to the pre-installation station after being sprayed with paint and dried, and the cleaning operator wipes the interior of the fuel tank with a rag soaked in hot water equipped with a cleaning agent. After completion, use the suction pipe of an industrial vacuum cleaner to extend into the fuel tank to absorb dust, steel shots and other particles from all sides and corners inside the fuel tank. But there are following defects in this cleaning method: [0003] 1. Due to the different types of forklifts, the internal size and structure of the fuel tank are different, especially the dead corners on the edge and the distance are far away. Due to the limitation of the leng...

Problems solved by technology

[0003] 1. Due to the different types of forklifts, the internal size and structure of the fuel tank are different, especially the dead corners on the edge and the distance are far away. Due to the limitation of the length of the arm, the operator's hand cannot touch it, so this part cannot be wiped.

[0004] 2. During the welding process of the steel plate on the inner wall of the fuel tank, a large amount of oxide skin and other impurities are produced due to high temperature. These impurities cannot be removed with a wet rag, even with an industrial vacuum cleaner, resulting in the cleaning quality of the fuel tank cannot be guaranteed

[0005] 3. After wiping with a wet rag, part of the cleaning fluid will remain on the inner wall of the fuel tank, and this part of the cleaning fluid cannot be removed by the subsequent vacuum cleaner, and can only be dried by free evaporation, so it is easy to produce water rust on the inner wall of the fuel tank and affect the oil quality

[0006] 4. Since the hot water equipped with cleaning agent is weakly alkaline, and the frame just off the assembly line still retains a residual temperature of about 30-40°C, when the operator is wiping, the hot water evaporates and produces harmful gases that will cause harm to the operator. lasting damage

[0007] 5. In order to ensure that the wiping area is enlarged and the corners are wiped as much as possible, the operator needs to extend his arms into the fuel tank as much as possible, causing the shoulder blades and arms to frequently collide with the fuel tank port and be injured
