[0002] With the development of industry, various materials and raw materials are mined, transported and refined. Tanks are inevitably used in the process of transportation and refining. According to the actual needs of production and life, the materials and shapes of tanks are very different. According to the different materials, there are generally: polyethylene storage tanks, polypropylene storage tanks, fiberglass storage tanks, ceramic storage tanks, rubber storage tanks, stainless steel storage tanks, etc. According to the different shapes, there are generally: tanks are mainly divided into three types according to their shapes: spherical tanks, horizontal cylindrical tanks and vertical cylindrical tanks; and after the tank is used for transportation and refining, there will be residual liquid inside it. If the tank is not cleaned, it will affect the next use of the tank. Therefore, the tank needs to be cleaned after being used for transportation and refining.

[0003] After searching, the Chinese patent application number 201520117079.6 discloses a three-dimensional rotating nozzle for cleaning large-volume cylindrical tanks in coal chemical and petroleum enterprises. It has a cylindrical cage fixed bracket composed of an upper fixed plate, a lower fixed plate and a plurality of connecting screws between the plates. A vertical rod section with a T-shaped spray rod inside is inserted into the cylindrical cage fixed bracket from the top of the cylindrical cage fixed bracket along the center line. The lower end of the vertical rod section of the T-shaped spray rod is inserted into a liquid inlet pipe joint. The upper part of the vertical rod section of the T-shaped spray rod is connected to the upper fixed plate through a tapered bearing. The two nozzle pipes are arranged at both ends of the straight rod section of the T-shaped spray boom, and are arranged at an arc angle of 45 degrees relative to the straight rod section, and the spray directions are opposite. The lower part of the liquid inlet pipe joint is connected to the lower fixed plate through an interface flange. The above patent has the following shortcomings: the nozzle pipes at both ends of the straight rod section of the T-shaped spray boom in the patent are arranged at an arc angle of 45 degrees, and the angle is fixed. Although the reverse force generated by the nozzle during the spraying process can make the T-shaped spray boom rotate continuously, it can only clean the horizontal plane relative to the nozzle pipe, and cannot clean the tank from the vertical plane.

[0032] The present invention will be further described below with reference to the embodiments. Example

[0033] A tank cleaning nozzle device, such as Figure 1-3As shown, it includes a nozzle body 100, and the nozzle body 100 includes a bearing ring body 101, a first frustum cover 110, and a second frustum cover 120. The first frustum cover 110 and the second frustum cover 120 are fixedly installed on the upper and lower sides of the bearing ring body 101 respectively. A sealing ring is provided between the first frustum cover 110 and the second frustum cover 120 and the bearing ring body 101. The sealing ring ensures the sealing between the bearing ring body 101, the first frustum cover 110 and the second frustum cover 120 to prevent water from flowing out of the nozzle body 100 and affecting the effect of the subsequent cleaning water flow; the outer wall of the top of the first frustum cover 110 is fixedly connected with a connecting The ring body 111, the connecting ring body 111 is connected to the external water pipe, the bottom end of the second frustum cover 120 is in a closed state, and is fixedly connected to a stainless steel nozzle 121; the first frustum cover 110 and the second frustum cover 120 are processed with evenly distributed water holes around them, the water holes on the first frustum cover 110 and the second frustum cover 120 are staggered with each other and the number is the same, the number of water holes on the first frustum cover 110 and the second frustum cover 120 is 2-8, the water holes on the first frustum cover 110 and the second frustum cover 120 are staggered with each other to avoid repeated cleaning of water sprayed from the upper and lower water holes, and the mutual staggering can speed up the cleaning speed;

[0034] It also includes an adjustment mechanism 200, which includes a movable mobile connecting rod 210 connected to an external driving device, and the outer wall of the bottom end of the mobile connecting rod 210 is fixedly connected to a support connecting rod 211. The outer walls of the bottom ends of the mobile connecting rod 210 and the support connecting rod 211 are connected to a rotating connecting rod 212 through a rotating shaft. The adjustment mechanism 200 also includes two mobile bearing columns 220 on the same central axis, which are respectively located inside the first frustum cover 110 and the second frustum cover 120. One end of the mobile bearing column 220 is rotatably connected to a connecting bead 222, and one end of the rotating connecting rod 212 is fixedly connected to the connecting bead 222. On one side of the bead 222, the movable supporting column 220 is fixedly connected with evenly distributed adjusting rods 221 around it, and the adjusting rods 221 are respectively located inside the water outlet holes of the first conical cover 110 and the second conical cover 120, and the angle between the adjusting rod 221 and the horizontal line is 0-45 degrees. One end of the adjusting rod 221 is fixedly connected with a cross spray ring 223; the angle between the adjusting rod 221 and the horizontal line is 0-45 degrees, and the number of adjusting rods 221 on each movable supporting column 220 is consistent with the number of water outlet holes on the first conical cover 110 and the second conical cover 120 in the corresponding space, that is, the first conical cover 110 is fixed with the water outlet holes of the second conical cover 120. 0 and the water outlet holes on the second frustum cover 120 also have the same angle with the horizontal line, ensuring that the water sprayed by the nozzle device in this patent is sprayed obliquely, increasing the water spray coverage area, and the external driving device drives the two movable connecting rods 210 to move closer to or away from each other, thereby adjusting the two movable supporting columns 220 to move away from or closer to each other, thereby causing the adjusting connecting rod 221 to change its position in the water outlet holes of the first frustum cover 110 and the second frustum cover 120, so as to realize the change of the water outlet angle of the cross spray ring 223, thereby improving the flexibility and practicality of the device; the two adjacent adjusting connecting rods 221 on the same movable supporting column 220 are at The included angle of the projection on the horizontal plane is 45-180°. The projection of the adjusting link 221 on one of the movable supporting columns 220 on the horizontal plane is located at the bisector of the angle of the projection of the two adjusting links 221 on the other movable supporting column 220 on the horizontal plane. The projection of the movable link 210 on the horizontal plane is located at the bisector of the angle of the projection of the two adjacent adjusting links 221 on the upper and lower movable supporting columns 220 on the horizontal plane. The movable link 210 is located between the upper and lower adjusting links 221 and has a larger movable area in the case of its own shape, thereby avoiding collision with the adjusting link 221.

[0035] The apparatus also includes a plurality of telescopic nozzles 300, which are respectively disposed at the water outlets of the first and second truncated cone covers 110 and 120, and whose inner walls are fixedly connected to the cross spray ring 223. The telescopic nozzles 300 are made of one of rubber and PVC. The preferred material of the telescopic nozzles 300 of the present invention is rubber, which is low in cost and has good sealing and ductility.

[0036] like Figure 4 As shown, the preferred angle between the adjusting connecting rod 221 and the horizontal line of the present invention is 30°;

[0037] like Figure 5 As shown, the preferred number of water outlets on the first conical cover 110 and the second conical cover 120 in this embodiment is four, that is, the angle between the projections of two adjacent adjusting links 221 on the same movable supporting column 220 on the horizontal plane is 90°, and the angle between the projection of the adjusting link 221 on one movable supporting column 220 on the horizontal plane and the two adjacent adjusting links 221 on the other movable supporting column 220 on the horizontal plane is 45°, and the angle between the rotating link 212 and the adjacent adjusting link 221 on the horizontal plane is 22.5°; the four water outlets on the first conical cover 110 and the second conical cover 120 can fully clean the four directions of the front, back, left and right inside the tank body, and the water outlet holes on the first conical cover 110 and the second conical cover 120 are staggered with each other, further increasing the cleaning area;

[0038] In this embodiment, the device is installed on the water pipe through the connecting ring body 111, the movable connecting rod 210 is connected to the external driving device, and then the nozzle device is placed inside the tank to be cleaned, and water is passed into the water pipe. At this time, the water flows into the nozzle body 100, and then passes through the water outlet holes on the first frustum cover 110 and the second frustum cover 120 and the telescopic nozzles 300 and 213 to flush the inside of the tank. The staff adjusts the height of the spray according to the position of the water sprayed by the nozzle device, that is, the external driving device drives the two movable connecting rods 210 to move closer to each other. At this time, the two movable supporting columns 220 move away from each other, and the adjusting link 221 located inside the first conical cover 110 moves upward, causing the telescopic nozzle 300 on the first conical cover 110 to flip upward and extend, while the adjusting link 221 located inside the second conical cover 120 moves downward, causing the telescopic nozzle 300 on the second conical cover 120 to flip downward and extend, thereby increasing the angle between the upper and lower water sprays. When the two movable links 210 are driven away from each other, the angle between the upper and lower water sprays becomes smaller, thereby adjusting the cleaning range inside the tank. Example

[0039] like Figure 6As shown, the preferred number of water outlets on the first conical cover 110 and the second conical cover 120 in this embodiment is six, that is, the angle between the projections of two adjacent adjusting links 221 on the same movable supporting column 220 on the horizontal plane is 60°, and the angle between the projection of the adjusting link 221 on one movable supporting column 220 on the horizontal plane and the two adjacent adjusting links 221 on the other movable supporting column 220 on the horizontal plane is 30°, and the angle between the rotating link 212 and the adjacent adjusting link 221 on the horizontal plane is 15°, totaling twelve water outlets. Although more water is required, the cleaning effect is better and the cleaning speed is faster than that of a total of eight water outlets.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
