Description

Technical Field

[0001] The invention relates to the technical field of spray machines, in particular to a spray cooling device for a spherical storage tank. Background Art

[0002] Steel welded spherical storage tanks are spherical pressure-bearing metal containers and are important objects in electromechanical installation projects. Spherical tanks contain high-pressure gases or liquefied gases, most of which are flammable and explosive media and are very dangerous. The installation and construction are difficult and require high quality. The spherical tank consists of a spherical tank body, a support and accessories. The spherical tank body is a spherical container welded together from spherical shell plates, which is the pressure-bearing part of the spherical tank. The support of the spherical tank is often a column support made of multiple steel pipes, with the equatorial tangent column being the most common. The accessories of the spherical tank include external escalators, valves, instruments, and some large spherical tanks also have internal rotating ladders.

[0003] During the cleaning process, since the inner wall of the spherical storage tank is curved, the common and simple direct spraying is difficult to adapt to the more complex inner wall shape of the spherical storage tank. The resulting spraying effect is single, which leads to unsatisfactory cooling effect and reduces production efficiency. In addition, when placing the spray cooling structure, the spherical tank has a special structure, which is not convenient for the stable placement of the spray cooling structure. The resulting tilt and distortion will make the spray cooling operation more difficult, reducing its efficiency. Summary of the invention

[0004] In order to make up for the above deficiencies, the present invention provides a spray cooling device for a spherical storage tank that overcomes the above technical problems or at least partially solves the above problems.

[0005] The present invention is achieved in that:

[0006] The present invention provides a spray cooling device for a spherical storage tank, comprising a cover plate, a spray mechanism is provided at the lower part of the cover plate, and the spray mechanism comprises:

[0007] A main rod, the main rod is movably inserted at the center of the cover plate, and a movable disk is fixedly connected to the bottom of the main rod;

[0011] In one embodiment of the present invention, an array mounting ring is provided at the top of the folding rod, and a swivel mounting ring is fixedly connected to the other end of the bottom of the folding rod.

[0012] In an embodiment of the present invention, the bottom of the cover plate is an arc-shaped groove with a concave shape, and an anti-slip pad is provided at the bottom of the cover plate.

[0013] In an embodiment of the present invention, a first opening is formed on the cover plate, and the first opening and the second opening are located on the same vertical line.

[0014] In one embodiment of the present invention, a cross limiting rod is provided at the bottom of the movable disk, and the top of the cross limiting rod overlaps with the lower surface of the fixing ring.

[0015] In an embodiment of the present invention, the chassis is provided with a second opening, and there are two second openings, which are respectively located at the top and the side of the chassis.

[0016] In an embodiment of the present invention, a fixing mechanism is provided on the side of the cover plate, and the fixing mechanism includes a second mounting block, and a limiting binding belt is inserted into the second mounting block.

By setting up a fixing mechanism, the stable structure can ensure that the nozzle always remains in the predetermined position and angle, achieving precise spray cooling of specific areas of the tank. For example, for parts of the tank that are prone to uneven heating, such as the top or bottom, a stable device can ensure that the nozzle continues to cool it accurately, avoiding uneven spraying due to shaking or displacement of the device, so that the entire tank surface can obtain a stable and consistent cooling effect. Just like in a long cooling process, the stable structure can ensure that the amount of coolant received by each part and the cooling time are relatively stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0028] Reference Figure 1-Figure 4The present technical scheme provides a spray cooling device for a spherical storage tank, which includes a cover plate 1, a spray mechanism 2 is provided at the lower part of the cover plate 1, and the spray mechanism 2 includes: a main rod 201, a fixing ring 202, three vertical rods 203 and a folding rod 206, the main rod 201 is movably inserted in the center position of the cover plate 1, the bottom of the main rod 201 is fixedly connected with a movable disk 2011, the fixing ring 202 is sleeved on the outer ring of the movable disk 2011, the three vertical rods 203 are arranged at the bottom of the fixing ring 202, the bottom of the three vertical rods 203 is fixedly connected with a chassis 204, one end of the folding rod 206 is movably connected with a first mounting block 205 through an insertion shaft, and the first mounting block 205 is fixedly connected to the side of the main rod 201, and the bottom of the cover plate 1 is an arc-shaped slot with an inward concave shape, The bottom of the cover plate 1 is provided with an anti-slip pad, and the cover plate 1 is provided with a first opening 101, and the first opening 101 and the second opening 2041 are located on the same vertical line. The top of the folding rod 206 is provided with an array mounting ring 2061, and the other end of the bottom of the folding rod 206 is fixedly connected with a swivel mounting ring 2062. The bottom of the movable disk 2011 is provided with a cross limiting rod 2012, and the top of the cross limiting rod 2012 overlaps the lower surface of the fixed ring 202. The chassis 204 is provided with a second opening 2041, and there are two second openings 2041. The two second openings 2041 are respectively located at the top and the side of the chassis 204, and the limiting strap 302 is put on the spherical tank, and one end is fixed by the second mounting block 301, and the limiting strap 302 and the spherical surface are connected. The length of the contact is adjustable to adapt to spherical tanks of different sizes. After the installation is completed, the top of the limit strap 302 is tightened and fixed. At this time, the cover plate 1 is just located at the top of the sphere. Since the main rod 201 can move up and down, when the bottom plate 204 does not contact the bottom of the inner wall of the sphere, the folding rod 206 is naturally vertically downward. At this time, the direction of spray cooling is aimed at the bottom of the inner wall of the spherical tank. After the bottom plate 204 contacts the bottom of the inner wall of the spherical tank, the movable plate 204 leaves the fixed ring 202. Relatively, the fixed ring 202 moves upward, and after contacting the bottom of the folding rod 206, one end of the folding rod 206 is lifted up. Specifically, the other end of the folding rod 206 makes an arc motion from bottom to top. In this process, the spray cooling head installed on the array mounting ring 2061 is moved by Spray the inner wall of the spherical tank from bottom to top. If spray cooling is required repeatedly, just repeat the above operation. Combined with the cover plate 1, when the spraying direction is vertically upward, the sprayed liquid will flow back along the cover plate 1 and will not splash. The suction pipe will pass through the first opening 101 to the second opening 2041 to discharge the accumulated water at the bottom of the inner wall of the spherical tank. The spray head can be folded like an umbrella rib and can spray in all directions in the vertical direction. Combined with the annular spray head, the direction of the spray head can be flexibly adjusted according to the temperature difference at different positions inside the tank body, so as to achieve a more uniform cooling effect. By accurately adjusting the direction of the spray head, the coolant can be sprayed more concentratedly and effectively to the key parts that need cooling, thereby reducing the waste of coolant and improving the cooling efficiency.

[0029] Reference Figure 1-Figure 4 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a fixing mechanism 3 is provided on the side of the cover plate 1, and the fixing mechanism 3 includes a second mounting block 301, and a limiting strap 302 is inserted on the second mounting block 301. There are four limiting straps 302, and the bottoms of the four limiting straps 302 are fixedly connected to each other. By setting the fixing mechanism, the stable structure can ensure that the nozzle always remains at a predetermined position and angle, so as to achieve precise spray cooling of specific areas of the tank body. For example, for parts of the tank body that are prone to uneven heating, such as the top or bottom, a stable device can ensure that the nozzle continues to accurately cool them, avoiding uneven spraying due to shaking or displacement of the device, so that the entire tank surface can obtain a stable and consistent cooling effect, just like in a long cooling process, the stable structure can make the amount of coolant received by each part and the cooling time relatively stable.

[0030] Specifically, the working process or working principle of the spray cooling device for spherical storage tanks is as follows: after the stored materials in the storage tank are transferred out, there will inevitably be some residue on the inner wall of the tank. If it is not cleaned in time, the liquid contained in the storage medium will evaporate a certain amount of water, and the residual liquid is likely to become thick, solidified or even adhere to the inner wall. Therefore, the inner wall of the tank needs to be sprayed and cooled and cleaned in time. Similarly, for spherical tanks that are not used or are about to be used, they also need to be cleaned when they have not been used for a certain period of time and have dust. The specific operation steps are as follows: put the limiting strap 302 on the spherical tank, and one end passes through the second installation The mounting block 301 is fixed, and the contact length between the limiting band 302 and the spherical surface is adjustable to adapt to spherical tanks of different sizes. After the installation is completed, the top of the limiting band 302 is tightened and fixed. At this time, the cover plate 1 is just located at the top of the sphere. Since the main rod 201 can move up and down, when the bottom plate 204 does not contact the bottom of the inner wall of the sphere, the folding rod 206 is naturally vertically downward. At this time, the direction of spray cooling is aimed at the bottom of the inner wall of the spherical tank. After the bottom plate 204 contacts the bottom of the inner wall of the spherical tank, the movable plate 204 leaves the fixing ring 202. Relatively, the fixing ring 202 moves upward. After contacting the bottom of the folding rod 206, the folding rod 2 One end of 06 is lifted up, which is specifically manifested in that the other end of the folding rod 206 makes an arc movement from bottom to top. During this process, the spray cooling head installed on the array mounting ring 2061 sprays the inner wall of the spherical tank from bottom to top. If spray cooling is required for multiple times, it is only necessary to repeat the above operation in both directions. Combined with the cover plate 1, when the spraying direction is vertically upward, the sprayed liquid will flow back along the cover plate 1 without spilling. The water suction pipe is connected to the second opening 2041 through the first opening 101 to discharge the accumulated water at the bottom of the inner wall of the spherical tank. Furthermore, when it is necessary to spray the outer wall of the tank body, the device can be removed from the limit tie at this time. The parts other than the belt 302, the second mounting block 301 and the cover plate 1 are placed around the outside of the spherical tank, and the lower half of the spherical tank is spray-cooled around according to the above operating method. When the upper half of the spherical tank needs to be spray-cooled, it only needs to be placed on the top of the spherical tank. The same as the above movement principle, during the process of the folding rod 206 changing from a vertical hanging state to a horizontal surrounding state, the spraying direction completely covers the upper half of the surface of the spherical tank. The combination of the two can perform all-round spray cooling on the outer surface of the spherical tank. In summary, the device can spray-cool both the inside of the tank body and the outside of the tank body.

[0031] It should be noted that the cover plate 1 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
