Detailed Description
As shown in attached figure 1, the steel cylinder inner wall cleaning device comprises a spray head 1, a hose 2, a pair of wheels 3 and a high-pressure cleaning machine 4. The spray head 1 is a high-pressure spray head as shown in figure 2, the lower end of the spray head is provided with a water spray hole, the side surface of the spray head is uniformly distributed with 3-6 water spray holes, the water spray direction is upward at an angle of about 15-20 degrees, the water surface sprayed when the horizontal circumferential direction and the axis form an included angle of 20-30 degrees is in an umbrella shape, and the water column can be automatically rotated by a reaction force generated when the water column is laterally sprayed. The main body material of shower nozzle is the stainless steel, and shower nozzle trompil part is a rotatable copper sheathing, has under the fluidic reaction force effect of certain rotation angle, drives the copper sheathing rotation. The rotating nozzle is beneficial to uniformly cleaning the inner wall of the steel cylinder. The hose 2 is a hose bearing high pressure, the rated pressure of the high-pressure cleaning machine 4 is 25MPa, the pair wheel 3 is provided with a groove, the groove is coated with rubber, and the hose is positioned in the rubber groove and is conveyed downwards or withdrawn upwards under the action of friction force of the pair wheel 3. Two ends of the hose 2 are respectively connected with the high-pressure cleaning machine 4 and the spray head 1, and the hose 2 moves up and down through the pair of wheels 3.
As shown in attached figure 1, a steel cylinder 5 is placed in a vertical pressure test well 6 before being cleaned, a water pump 7 is installed at the bottom of the pressure test well 6, cleaning water can be pumped out of the pressure test well 6 by the water pump, and the water level is kept not to exceed the lower bottle opening of the steel cylinder, so that smooth downward flow of the cleaning water on the inner wall of the steel cylinder is facilitated. The nozzle 1 is mounted, and a mark is previously made on the high-pressure hose 2 according to the length of the steel cylinder, wherein the mark indicates that the nozzle reaches a set position. Starting the high-pressure cleaning machine 4 and the coupling wheel 3, the hose 2 gradually extends into the steel cylinder 5 from the bottle opening at the upper end of the steel cylinder 5. The downward high-pressure water flow of the spray head is beneficial to keeping the hose vertical and can effectively clean metal dust flowing from the upper part of the inner wall to the arc part of the inner wall of the lower seal head. The lateral high-pressure water column can effectively clean the inner surface of the steel cylinder. When the mark on the hose reaches the upper end of the bottle mouth, the mark indicates that the bottle mouth is cleaned to the bottom, the hose is moved after staying for about 30 seconds, the arc part of the bottle mouth end enclosure is cleaned more thoroughly, then the nozzle reciprocates twice up and down, and the steel bottle is lifted out after the cleaning.
The device simple structure, the steel bottle inner wall clearance is thorough, and internal surface cleaning quality is good, and the cleaning efficiency is high.
