AI Technical Summary
When feeding, the liquid is sprayed directly onto the inner wall of the horizontal storage tank, causing damage to the anti-corrosion layer. In addition, the impact direction of the external water pipe cannot be accurately located, and there is a lack of a fixed structure.
The design incorporates components such as a buffer ring plate, a buffer cover, an annular flow guide ring, a flow-slowing tank, and an arc-shaped clamp. The combined use of these components ensures that the liquid impacts the buffer structure first, rather than the inner wall of the tank, and the arc-shaped clamp is used to fix the water pipe end to control its orientation.
This effectively prevents liquid from directly impacting the inner wall of the storage tank, protects the anti-corrosion layer, ensures accurate water spray direction, and prevents damage to the corrosion layer on the inner wall of the storage tank.

Description
Technical Field
[0001] This utility model belongs to the technical field of storage tanks, and in particular relates to an anti-impact structure for the pipe opening of a horizontal storage tank. Background Technology
[0002] Horizontal storage tanks are a common type of storage equipment, mainly used for storing liquids or gases, and are widely used in industries such as petrochemicals, chemicals, pharmaceuticals, and food. They can be classified according to different materials, locations, installation methods, and shapes. Examples include horizontal storage tanks on water trucks and horizontal storage tanks on chemical transport vehicles. As storage equipment, storage tanks must be filled with sufficient materials for storage and use. However, in actual feeding operations, the following drawbacks still exist:
[0003] Taking the filling of water into the horizontal storage tank on the sprinkler truck as an example, water from the outside needs to be injected into the horizontal storage tank through the pipe on the horizontal storage tank. However, the liquid will be sprayed directly onto the inner wall of the horizontal storage tank. Over time, this will damage the anti-corrosion layer on the inner wall of the horizontal storage tank. Therefore, a certain buffer structure is needed to reduce the impact of the liquid on the tank wall in order to extend the service life.
[0004] Secondly, many horizontal storage tanks have large pipe diameters, making it impossible to directly connect to external water pipes. Water pipes need to be inserted into the pipe openings, but the orientation of the pipe ends is uncertain. Even with a buffer structure to prevent impact, it is still necessary to ensure that the liquid being transported by the water pipe is 100% directed towards the buffer structure. However, current feeding operations lack such a structure to fix the water pipe. Utility Model Content
[0005] The purpose of this utility model is to provide an anti-impact structure for the pipe opening of a horizontal storage tank. By setting up a buffer ring plate, a buffer cover, an annular guide ring, a slow-flow tank, an inlet pipe, and an arc-shaped clamp, it solves the problems of liquid being directly sprayed onto the inner wall of the horizontal storage tank when adding liquid, causing damage to the anti-corrosion layer, and the inability to accurately position the impact direction of the external water pipe when liquid is introduced into the horizontal storage tank from the pipe opening.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a horizontal storage tank inlet anti-impact structure, including a storage tank body, a liquid inlet pipe, a buffer ring plate, a buffer cover, an annular guide ring and a slow-flow tank, wherein the liquid inlet pipe is fixed through the center of the top of the storage tank body;
[0008] A frustum-shaped buffer cover is installed inside the main body of the storage tank below the inlet pipe, and the bottom end of the buffer cover is fixed to the upper end of the buffer ring plate.
[0009] The inner cavity of the buffer ring plate is provided with an annular flow guide ring, and a hemispherical slow-flow tank is fixed on the inner wall of the annular flow guide ring.
[0010] Furthermore, the inside of the liquid inlet pipe is provided with two arc-shaped clamps, each of which has ear plates fixed on both sides, and one arc-shaped clamp is fixed while the other arc-shaped clamp is movable.
[0011] Furthermore, two sets of sliding rods are fixed on the inner wall of the liquid inlet pipe. The fixed arc-shaped clamp is fixed to the outside of the sliding rod through the ear plates on both sides. The movable arc-shaped clamp is slidably set outside the sliding rod through the ear plates on both sides. A screw is rotatably connected at the center of the outer curved surface of the movable arc-shaped clamp. The end of the screw away from the arc-shaped clamp is threaded through the liquid inlet pipe and extends out and is fixed with a handwheel.
[0012] Furthermore, a ring array of support rods is fixed on the outer curved surface of the buffer ring plate, and the end of the support rod away from the buffer ring plate is fixed to the inner wall of the tank body.
[0013] Furthermore, a ring-shaped array of support rods is fixed on the outer curved surface of the lower part of the slow-flow tank, and the end of the support rod away from the slow-flow tank is fixed to the inner bottom of the tank body.
[0014] Furthermore, the circumference of the slow-flow tank is provided with a flow guide hole distributed in a ring array, the inner curved surface of the ring flow guide ring is provided with a through hole one distributed in a ring array, and the outer curved surface of the ring flow guide ring is provided with a through hole two distributed in a ring array.
[0015] Furthermore, the guide hole and the first through hole are interconnected, and the inner diameter and number of the guide hole and the first through hole are equal. The inner diameter of the second through hole is smaller than that of the first through hole, and the number of the second through hole is greater than that of the first through hole.
[0016] This utility model has the following beneficial effects:
[0017] This invention solves the problem of liquid directly spraying onto the inner wall of a horizontal storage tank, causing damage to the anti-corrosion layer, by incorporating a buffer ring plate, a buffer cover, an annular guide ring, and a flow-retarding tank. When liquid is added to the tank body, it impacts the interior. The liquid first rushes into the flow-retarding tank. After a certain level of liquid is filled, it overflows from the guide hole, passes through through-hole one, and enters the annular guide ring. Once the annular guide ring is full, liquid is ejected from through-hole two, impacting the inner wall of the buffer ring plate. If the liquid pressure is insufficient, the liquid exiting through through-hole two will not be ejected but will fall directly. If the water flow is too large, the flow-retarding tank cannot handle it all, and some liquid will rush out along the spherical inner wall of the flow-retarding tank, hitting the inner wall of the buffer cover. Throughout the process, regardless of the impact and scouring of the liquid, it will not directly impact the inner wall of the tank body, effectively preventing liquid from impacting the inner wall of the horizontal storage tank and avoiding damage to the anti-corrosion layer.
[0018] This invention solves the problem of inaccurate positioning of the impact direction of the external water pipe when liquid is introduced into a horizontal storage tank through the design of an inlet pipe and arc-shaped clamps. The premise for the use of the buffer and anti-impact structure is that the liquid impacts the buffer structure precisely and does not spray in all directions, otherwise it will still cause damage to the corrosion layer of the inner wall of the storage tank. Therefore, when adding liquid, the end of the water pipe is placed between the two arc-shaped clamps inside the inlet pipe to clamp and fix it, so that the spray direction of the water pipe is accurate and does not spray in all directions, ensuring that the water flow sprayed from the water pipe impacts the slow-flow tank directly.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0029] Please see Figure 1-6 As shown, this utility model is a horizontal storage tank inlet anti-impact structure, including a storage tank body 1, an inlet pipe 2, a buffer ring plate 3, a buffer cover 4, an annular guide ring 5, and a slow-flow tank 6. The inlet pipe 2 is fixed through the center of the top of the storage tank body 1.
[0030] The main body of the storage tank 1 is a horizontal storage tank, and the liquid inlet pipe 2 is used as the liquid inlet to facilitate the entry of external liquid into the interior of the main body of the storage tank 1.
[0031] A frustum-shaped buffer cover 4 is installed inside the main body 1 of the storage tank below the inlet pipe 2. The bottom end of the buffer cover 4 is fixed to the upper end of the buffer ring plate 3.
[0032] The upper inner diameter of the buffer cover 4 is smaller than the lower inner diameter, and the upper port size of the buffer cover 4 is larger than the port size of the inlet pipe 2.
[0033] An annular guide ring 5 is provided in the inner cavity of the buffer ring plate 3, and a hemispherical slow-flow tank 6 is fixed on the inner wall of the annular guide ring 5.
[0034] The liquid entering from the inlet pipe 2 first impacts the slow-flow tank 6, and then enters the annular guide ring 5. Excess liquid rushes out along the inner wall of the slow-flow tank 6. If the impact force is too large, the liquid rushing out of the slow-flow tank 6 will impact the inner wall of the buffer cover 4, and will not impact the inner wall of the main body of the storage tank 1.
[0035] The inlet pipe 2 is equipped with two arc-shaped clamps 201. Each arc-shaped clamp 201 has ear plates 2011 fixed on both sides. One arc-shaped clamp 201 is fixed and the other arc-shaped clamp 201 is movable.
[0036] The premise for using the buffer and shockproof structure is that the liquid impacts the buffer structure precisely and does not spray in all directions. Therefore, when adding liquid, the end of the water pipe is placed between the two arc-shaped clamps 201 inside the liquid inlet pipe 2 to clamp and fix it, so that the water pipe sprays in an accurate direction.
[0037] Two sets of slide rods 202 are fixed on the inner wall of the liquid inlet pipe 2. The fixed arc-shaped clamp 201 is fixed to the outside of the slide rod 202 through the ear plates 2011 on both sides. The movable arc-shaped clamp 201 is slidably set outside the slide rod 202 through the ear plates 2011 on both sides. A screw 203 is rotatably connected at the center of the outer curved surface of the movable arc-shaped clamp 201. The end of the screw 203 away from the arc-shaped clamp 201 is threaded through the liquid inlet pipe 2 and extends out and is fixed with a handwheel.
[0038] The end of the water pipe is placed between two arc-shaped clamps 201. By rotating the screw 203 with the handwheel, the movable arc-shaped clamp 201 moves closer to the fixed arc-shaped clamp 201 until the end of the water pipe is fixedly clamped. During this process, the movable arc-shaped clamp 201 moves on both sides of the ear plate 2011 on the slide rod 202, so that it will not deflect and can only move horizontally.
[0039] A ring array of support rods 301 is fixed on the outer curved surface of the buffer ring plate 3. The end of the support rod 301 away from the buffer ring plate 3 is fixed to the inner wall of the tank body 1. The buffer ring plate 3 is fixed to the inner wall of the tank body 1 by the support rods 301 to maintain structural stability.
[0040] Support rods 601 arranged in a ring array are fixed on the outer curved surface of the lower part of the slow-flow tank 6. The end of the support rods 601 away from the slow-flow tank 6 is fixed to the inner bottom of the tank body 1.
[0041] The lower part of the slow-flow tank 6 is fixed to the main body of the storage tank 1 by a support rod 601, which provides stable support for the slow-flow tank 6.
[0042] The slow-flow tank 6 has a ring-shaped array of flow guide holes 602 through its periphery, the inner curved surface of the annular flow guide ring 5 has a ring-shaped array of through holes 501 through its inner curved surface, and the outer curved surface of the annular flow guide ring 5 has a ring-shaped array of through holes 502 through its outer curved surface.
[0043] The guide hole 602 and the through hole 501 are interconnected, and the inner diameter and number of the guide hole 602 and the through hole 501 are equal. The inner diameter of the through hole 502 is smaller than the inner diameter of the through hole 501, and the number of through holes 502 is greater than the number of through holes 501.
[0044] The liquid first rushes into the slow-flow tank 6. After the slow-flow tank 6 is filled with a certain level of liquid, it overflows from the guide hole 602, passes through the first through hole 501 and enters the annular guide ring 5. After the annular guide ring 5 is filled with liquid, the liquid is ejected from the second through hole 502 and impacts the inner wall of the buffer ring plate 3. If the liquid pressure is insufficient, the liquid discharged from the second through hole 502 will not be ejected, but will fall directly.
[0045] The specific working principle of this utility model is as follows: First, the main body 1 of the storage tank is a horizontal storage tank, and the liquid inlet pipe 2 is used as the liquid inlet. First, the end of the external water pipe is set between two arc-shaped clamps 201. By rotating the screw 203 with the handwheel, the movable arc-shaped clamp 201 moves closer to the fixed arc-shaped clamp 201 until the end of the water pipe is fixed and clamped, so that the spray direction of the water pipe is accurate and aimed at the slow flow tank 6.
[0046] The liquid first rushes into the slow-flow tank 6. After the slow-flow tank 6 is filled with a certain level of liquid, it overflows from the guide hole 602, passes through the first through hole 501 and enters the annular guide ring 5. If the water pressure is sufficient, after the annular guide ring 5 is filled with liquid, the liquid is ejected from the second through hole 502 and impacts the inner wall of the buffer ring plate 3. If the liquid pressure is insufficient, the liquid discharged from the second through hole 502 will not be ejected, but will fall directly. If the water flow is too large, the slow-flow tank 6 cannot handle it all, and some liquid will rush out along the spherical inner wall of the slow-flow tank 6 and hit the inner wall of the buffer cover 4. Throughout the process, no matter how the liquid impacts and washes, it will not directly impact the inner wall of the main body of the storage tank 1, ensuring sufficient impact resistance and avoiding damage to the corrosion layer.
[0047] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
