同じ形で必ず出てくる。When it is difficult to remove the deposits on the inner wall of the tank,
Although the locus of the mesh is made slower by moving slowly, it will pass through the same locus no matter how many times it is reciprocated, so the upper and lower pitches will only become dense, and the positions where high-pressure jets do not pass always appear in the same shape. Come on.

回転駆動される。When high-pressure water is supplied from the high-pressure hose 4, the cleaning device 2 rotates and sprays a high-pressure water jet on the inner wall of the tank 1. The cleaning device 2 moves up and down by the rotation of the hose reel 5 that winds the high-pressure hose 4. The hose reel 5 is reversibly driven to rotate by a motor (not shown).

噛み合うギヤ１９が設けられる。The concrete structure of the cleaning device 2 is shown in FIGS. Water supply hole 12 to which the high pressure hose 4 is connected at the center
A rotary housing 11 is rotatably mounted around a fixed shaft 10 having A turbine 13 is coaxially and rotatably attached to the lower end of the fixed shaft 10 so that the turbine 1
The high-pressure water is jetted from the jet port 14 communicating with the water supply hole 12 toward the nozzle 3. The rotation of the turbine 13 is transmitted to the gear 17 of the intermediate shaft 16 by the gear 15. The intermediate shaft 16 penetrates a fixed platen 28 integrated with the fixed shaft 10, and a gear 19 that meshes with a gear 18 formed on the outer periphery of the rotary housing 11 is provided at the other end of the intermediate shaft 16.
【００１６】したがって、タービン１３の回転により中
間軸１６が回転すると、これに駆動されて回転ハウジン
グ１１が固定軸１０の回りを回転する。Accordingly, when the intermediate shaft 16 is rotated by the rotation of the turbine 13, the intermediate housing 16 is driven by this and the rotary housing 11 rotates around the fixed shaft 10.

する給水路２３を介して高圧水が供給される。On the other hand, the rotary housing 11 has a horizontal shaft 20.
Is horizontally projected, and the rotary sleeve 2 is attached to the horizontal shaft 20.
1 is rotatably fitted. The rotary sleeve 21 is provided with a pair of jet nozzles 22, and high-pressure water is supplied to the jet nozzles 22 through a water supply passage 23 that branches from the water supply hole 12 and penetrates the axis of the horizontal shaft 20.

Since it rotates around the
A high pressure seal 25 is also interposed between the horizontal shaft 20 and the rotary sleeve 21.

転する。A bevel gear 26 is formed on a part of the rotary sleeve 21, and a bevel gear 27 is also formed on the outer circumference of the stationary platen 28. As the rotary housing 11 rotates, the bevel gears 26 and 27 mesh with each other. The rotating sleeve 21 rolls along the outer periphery of the fixed platen 28. That is, the rotating sleeve 21 revolves around the fixed shaft 10 along the fixed platen 28 while rotating about the horizontal shaft 20.

に比例して変化する。Therefore, the injection nozzle 22 injects high-pressure water in the three-dimensional direction while rotating and revolving integrally with the rotary sleeve 21. The rotation speed of the injection nozzle 22 is proportional to the rotation speed of the turbine 13, and the rotation speed of the turbine 13 changes in proportion to the pressure of the high-pressure water colliding with the turbine 13 from the injection port 14.

え、高圧水を供給する。To explain the overall operation, when cleaning the tank 1, first, the sluice valve 3 is opened to rotate the motor of the hose reel 5 in the normal direction, and the washing device 2 is passed through the sluice valve 3 to a predetermined inside of the tank 1. Lower to the upper position of.
The high pressure pump P is operated, the three-way switching valve 8 is switched to the water supply side, and high pressure water is supplied.

この一部が噴射口１４よりタービン１３に向けて噴出

３を経由して噴射ノズル２２から噴出する。As the high-pressure water is supplied, the high-pressure water is guided from the high-pressure hose 4 to the water supply hole 12 of the fixed shaft 10 of the cleaning device 2,
A part of this is ejected from the injection port 14 toward the turbine 13 to rotate the turbine 13, and most of the same is supplied to the water supply passage 2
It is jetted from the jet nozzle 22 via 3.

の内壁に衝突し、壁面の付着物を剥離させる。On the other hand, the high-pressure hose 4 extends as the hose reel 5 rotates, and the cleaning device 2 descends at a predetermined speed. Therefore, the high-pressure jet jetted from the jet nozzle 22 draws a lozenge-shaped locus, and the tank 1
It collides with the inner wall of the and removes the deposits on the wall.

降は段階的に圧力を下げることもできる。By the way, according to the present invention, when the inside of the tank 1 is cleaned by the high-pressure jet while the cleaning device 2 is moved up and down, the first reciprocation is at a constant high pressure (depending on the purpose of use, for example, 100 kg / cm 2 to 350 kg). / C
m 2 ), the pressure control valve V is adjusted for the second reciprocation, and the pressure is adjusted to a predetermined value (for example, several kg / cm 2 to 10).
Cleaning is performed by reducing the pressure by kg / cm 2 ). However,
These are adjusted to the contents of the tank 1 to be washed, and after reciprocating at the same pressure several times, the pressure is reduced by a predetermined value to reciprocate several times, or the pressure is gradually reduced after the second time. You can also

目の部分のみを示してある。FIG. 4 shows the locus of the high-pressure jet jet to the inner wall of the tank 1 drawn by the jet nozzle 22 of the cleaning device 2. The injection nozzle 22 rotates horizontally (revolution)
However, since it rotates (rotates) around its axis, the loci drawn on the inner wall of the tank 1 are rhombic meshes. However, for convenience of explanation, only one rhombic mesh portion is shown in the drawing.

上下にゆっくりと移動させると、それだけ１往復に必要
な洗浄時間も長くかかる。In the case of this figure, the vertical movement speed of the injection nozzle 22 is higher in (A) than in (B), and therefore, when the injection nozzle 22 makes one revolution and returns to its original position, The vertical pitch with respect to the locus becomes larger than that in (B).
However, since the revolution speed is constant, the positions of the loci of the high-pressure jets in the circumferential direction are the same. Although the vertical pitch of (B) is smaller than that of (A) and the cleaning density is increased, in any case, the high-pressure jet jet passes the same trajectory during the ascending process and the descending process. Is always present as an unwashed part. In addition, if it is slowly moved up and down in this way, the cleaning time required for one reciprocation will be extended accordingly.

に比べて周方向の位置と上下の位置がずれる。By changing the supply pressure,
This is because the rotation speed of the turbine 13 changes, and the revolution speed and the rotation speed of the injection nozzle 22 change, so that the circumferential position and the vertical position deviate from those before the pressure changes.

れだけ高い密度の洗浄能力が得られる。In this way, since the loci of the high-pressure jets are deviated between the first reciprocation and the second reciprocation, the portions where the high-pressure jet does not pass are reduced, and the cleaning density is increased. Since the deposits on the inner wall of the tank 1 are usually separated by a single injection with respect to the passage portion of the high-pressure jet jet, by reducing the non-passage portion in this way, the cleaning ability of higher density can be obtained.
【００３５】さらに３往復目、４往復目と供給圧力を変

部分はさらに減少し、洗浄密度を飛躍的に高められる。When the supply pressure is further changed between the third and fourth reciprocations, different trajectories are passed, so that the non-passed portion is further reduced and the cleaning density can be remarkably increased.

しく悪い。On the other hand, if the vertical movement speed is made very slow without changing the supply pressure, the vertical pitch in FIG. Since a trace is drawn, there is still an unwashed portion left unwashed, and the time for reciprocation is very long, so that the washing efficiency is remarkably poor as compared with the present invention.

However, these operations are automatically performed. It can also be done on a daily basis.

The supply pressure of the high-pressure water is automatically controlled by outputting a signal from the controller.

Since the cleaning density is changed, the cleaning density can be increased without increasing the cleaning time and efficient cleaning can be performed.
