Description

Technical Field

[0001] This utility model relates to devices used in the chemical industry, and in particular to an anti-clogging storage tank device for materials that are prone to self-polymerization. Background Technology

[0002] Currently, there are two main types of bottom drain outlets widely used in the chemical industry: siphon drain outlets and bottom slotted drain outlets.

[0003] Siphon-type drain outlet: This type of outlet does not open directly at the bottom of the storage tank. Its structure is an inverted U-shaped siphon tube. The highest point of the siphon tube (siphon apex) is located at the working liquid level of the storage tank, while the drain outlet is located on the outside of the bottom of the tank. Because there is a certain space between the suction inlet and the tank bottom plate, a very small amount of liquid will always remain and cannot be sucked out, resulting in incomplete emptying of the storage tank and making tank cleaning somewhat difficult.

[0004] Bottom-grooved drain outlet: This is the most direct and simplest drain method. A groove is cut at the lowest point of the tank bottom plate to lower the position of the bottom suction inlet. It operates using gravity, and the drain outlet is typically located in the center of the tank bottom plate. The grooved area usually has welded drain pipes, which causes easily self-polymerizing materials to stagnate in the grooved area. The polymerization reaction continues, making this area a potential polymerization initiation point, forming viscous substances or even solid polymers, eventually completely clogging the drain outlet and valves. Once the drain outlet is blocked by self-polymers, unblocking becomes extremely difficult; furthermore, the groove weakens the structural strength, posing a risk of cracking.

[0005] Therefore, how to provide a simple, non-clogging storage tank device with a drainage structure for easily self-polymerizing materials has been a technical problem that engineers in the field of chemical equipment have been trying to solve. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an anti-clogging drainage system for storage tanks of easily self-polymerizing materials, which solves the problems of incomplete drainage and difficulty in cleaning storage tanks at the bottom of storage tanks used in the chemical industry.

[0007] To achieve the above-mentioned and other related objectives, this utility model is implemented by including the following technical solutions.

[0008] This utility model provides an anti-clogging storage tank device for easily self-polymerizing materials, including a storage tank body and a short drain pipe; the storage tank body includes at least a tank bottom plate and a tank side wall, and the tank side wall forms an arched drain outlet, the lowest point of which is flush with the inner surface of the tank bottom plate.

[0009] At the drain outlet, the tank bottom plate forms an extended flat portion relative to the tank side wall for welding the drain short pipe;

[0010] The short drain pipe has a tank connection part and a valve connection part formed sequentially along its length; the radial cross section of the tank connection part is arc-shaped corresponding to the edge of the drain outlet, and is welded to the side wall of the tank on the extended plane and at the drain outlet to form a sealed drain section.

[0011] In one embodiment, the welding is a bevel weld.

[0012] In one embodiment, the arc shape is a superior arc. Specifically, a drain outlet with a superior arc-shaped edge is formed on the side wall of the tank. Specifically, the radial cross-section of the tank body connection is a superior arc-shaped structure corresponding to the edge of the drain outlet. Specifically, the superior arc has a symmetrical structure.

[0013] In one embodiment, a drain valve is also connected to one end of the valve body connection. In a further embodiment, the drain valve is connected via a flange structure. In a further embodiment, the drain valve is a gate valve or a ball valve.

[0014] In one embodiment, the extended planar portion includes a first welded plate portion for direct welding to the tank bottom plate bevel at the drain outlet, and is ground flat to form a smooth and flush upper surface on the extended planar portion.

[0015] In one embodiment, the thickness of the first welding plate portion is greater than the thickness of the tank bottom plate, and the first welding plate structure forms a sunken step structure at the welding point with the tank bottom plate or its external extension, for thickening and reinforcing the tank bottom plate.

[0016] In one embodiment, the extended planar portion further includes a second welding plate structure for beveling between the first welding plate structure and the valve body connection portion for sealing and reinforcement.

[0017] In one embodiment, the thickness of the second welding plate structure is greater than the thickness of the first welding plate structure and the wall thickness of the valve body connection.

[0018] In one embodiment, the end arc structure of the tank connection part matches the drain port and is welded and sealed to the side wall of the tank.

[0019] In one embodiment, the dominant arc is 1.1 to 1.8 radians.

[0020] In one embodiment, the dominant arc is 1.2 to 1.7π radians.

[0021] As described above, the anti-clogging storage tank device for easily self-polymerizing materials of this invention has the following beneficial effects:

[0022] This application creatively proposes a novel anti-clogging storage tank device. Its drain outlet is located on the side wall and connected to the bottom plate as an edge, forming a smooth, planar drain pipe section by welding. This creates a new device that is easy to drain and clean, and boasts high structural strength, suitable for storing materials prone to self-aggregation. This structural improvement differs from existing technologies such as siphon-type drain outlets based on the siphon principle and bottom-grooved drain outlets with drain outlets typically located in the middle of the bottom plate. It offers advantages such as simple structure, no need for complex siphon pipe components, high structural strength, good safety, and high reliability. Attached Figure Description

[0042] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0043] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0044] This application aims to overcome the shortcomings of the prior art and provide a storage tank device that is simple in structure, fundamentally eliminates sewage dead zones, effectively prevents material self-aggregation and blockage, and is easy to maintain online.

[0045] To address the aforementioned issues, the applicant seamlessly connected the drain pipe and tank bottom plate using a design for the location of the drain outlet and a bevel welding method. This resulted in a smooth transition between the bottom surface of the drain pipe and the inner surface of the tank bottom plate, forming a continuous, non-protruding discharge surface and ensuring direct connection between the lowest point of the tank bottom and the drain pipe.

[0046] Specifically, the drain outlet is located on the side wall and at the bottom of the tank, with the tank bottom plate serving as the edge or limiting boundary of the drain outlet. The bottom of a portion of the drain pipe is cut off to form an open channel (with an arc-shaped radial cross-section), and then welded flush with the tank bottom plate. This flush welding means that the welded part not only closes the open channel, but also forms a smooth and flush welded plane on the inner bottom surface, thereby eliminating any depressions, protrusions, and fluid stagnation areas present in traditional structures. Materials can flow into the drain channel without obstruction, preventing self-aggregation and blockage from the source.

[0047] It has the following advantages:

[0048] 1) Simple structure and high reliability: The modification method is simple, no complex internal components (such as siphon tubes) are required, the structure has high strength and good safety;

[0049] 2) Easy online maintenance: Even if minor aggregation or blockage occurs, the straight and unobstructed channel allows for online flushing through the attached flushing port, eliminating the need to stop the tank for cleaning and resulting in extremely low maintenance costs.

[0050] 3) Excellent emptying effect: It ensures that the liquid in the tank can be 100% drained without residue, reducing material waste and subsequent cleaning work.

[0051] 4) Wide applicability: It is not only suitable for materials that are prone to self-polymerization, but also for all media that are prone to clogging, such as those that are prone to crystallization, contain solid particles, or have high viscosity.

[0052] 5) The modified methacrylic acid storage tank has been in use for 8 years without any issues such as polymerization, blockage, or leakage at the drain outlet. It has performed well and minimizes material waste during the tank cleaning process.

[0053] The following, in conjunction with the accompanying drawings, provides a more detailed explanation and illustration of the aforementioned solutions, complete schemes, and their technical effects.

[0054] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides an anti-clogging storage tank device for easily self-polymerizing materials, including a storage tank body 1 and a short drain pipe 2;

[0055] The tank body 1 includes at least a bottom plate 11 and a side wall 12. The side wall 12 has an arched drain outlet 13, the lowest point of which is flush with the inner surface of the bottom plate. At the drain outlet, the bottom plate 11 has an extended flat portion 111 relative to the side wall 12 for welding the drain pipe.

[0056] The short drain pipe 2 has a tank body connection portion 21 and a valve body connection portion 22 sequentially formed along its length. The radial cross-section of the tank body connection portion 21 is arc-shaped, corresponding to the edge of the drain outlet, and is sealed by welding to the extended plane portion 111 and the tank side wall at the drain outlet to form a sealed drain section. The sealing in this sealed drain section refers to the sealed connection between the storage tank body 1 and the short drain pipe 2. In a specific embodiment, the sealed connection can be achieved by beveling welding.

[0057] The arched sewage outlet in this application is like... Figure 5 As shown in Figure 13, its edge curve is part of a circular arc. Specifically, a drain outlet with a superior arc-shaped edge is formed on the side wall of the tank, that is, the drain outlet is a superior arc arch shape, such as... Figure 5As shown, the bottom edge boundary is defined by the tank bottom plate or the extended flat portion. Specifically, the radial cross-section of the tank body connection is an arc shape corresponding to the edge of the drain outlet. Specifically, this arc has a symmetrical structure.

[0058] In this application, the drain outlet 13 is formed on the side wall of the tank, that is, it is located on the side wall of the tank, near the bottom plate, and the drain outlet is limited by the bottom plate. This also means that the lowest point of the drain outlet 13 is flush with the inner surface of the bottom plate, allowing for the most thorough emptying. Specifically, as... Figure 5 As shown, the drain outlet 13 is formed on the side wall of the tank, and its edge on the side wall has a superior arc structure, with the bottom edge being the tank bottom plate 11 or the extended flat portion 111. This forms a drain outlet with a superior arc arch. This superior arc arch, which sits on the tank bottom plate, not only ensures that the lowest point of the drain outlet is flush with the inner surface of the tank bottom plate, but also does not affect the outflow volume and outflow rate.

[0059] In this application, such as Figure 1 and Figure 2 As shown, the bottom plate of a typical storage tank can have an extension section integrally formed with the tank interior, located at the bottom of the tank exterior. If the extension section is long enough, it can serve as the welding installation point for the short drain pipe in this application. If it is not long enough, it can be extended using welding blocks, such as by seamless welding. See this application for details. Figure 3 and Figure 4 The first welded plate structure 4 for extension and the second welded plate structure 5 for further reinforcement and sealing shown below are provided that the upper surface of the extended flat portion 111 (the first welded plate structure 4 and the second welded plate structure 5) can be smooth with the inner surface of the tank bottom plate and lie on the same plane.

[0060] In one specific embodiment, the welding is bevel welding. In this application, bevel welding ensures complete penetration, forming a fully fused weld; this helps control workpiece deformation and reduces defects such as porosity and slag inclusions.

[0061] In one specific embodiment, the arc shape is a dominant arc. This dominant arc can be referenced as follows: Figure 5 As shown in θ. In one specific embodiment, the dominant arc is 1.1 to 1.8π radians. In a more specific embodiment, the dominant arc is 1.2 to 1.7π radians. For example, it can be 1.2π radians, 1.3π radians, 1.4π radians, 1.5π radians, 1.6π radians, or 1.7π radians. More specifically, the arc-shaped structure of the tank connection matches the drain outlet 13, such as the drain outlet 13 also including a matching arc-shaped segment and a planar segment composed of part of the tank bottom plate; the size of the arc-shaped structure is consistent with the drain outlet 13, used for sealing connection by beveling welding; it can also be further as follows. Figure 5The diagram shows a welded reinforcing block 23.

[0062] In a like Figure 1 and Figure 2 In the specific embodiment shown, one end of the valve body connection 22 is also connected to a drain valve 3, such as through a flange structure. In a... Figure 1 and Figure 2 In the specific embodiment shown, the drain valve is connected via a flange structure.

[0063] In a like Figure 2 , Figure 3 and Figure 4 In the specific embodiment shown, the extended planar portion 111 includes a first welded flat plate structure 4, which is used to directly weld to the bevel of the tank bottom plate at the drain outlet. It is formed by grinding to create a smooth, flush upper surface and is used to weld the tank body connection portion 21, which has an open radial cross-section, onto it to form a sealed drain section. In the actual production of the drain function of the device in this application, a storage tank with the extended planar portion 111 (including the first welded flat plate structure 4) is first provided. Then, a drain pipe with the tank body connection portion 21 and the valve body connection portion 22 is welded to the drain outlet. Specifically, the bottom of the tank body connection portion 21 is cut off to form an open channel (with an arc-shaped radial cross-section). The end (free end) of the tank body connection portion 21 is sealed to the drain outlet through a welding structure. The bottom end (open bottom end) of the tank body connection portion is also fixed to the extended planar portion 111 by welding to form a closed, sealed drain channel.

[0064] In a like Figure 4 In the specific embodiment shown, the thickness t2 of the first welded plate structure 4 is greater than the thickness t1 of the tank bottom plate 11, and the first welded plate structure 4 forms a sunken step structure 41 at the welding point with the tank bottom plate 11 or its outer extension, which is used to thicken and reinforce the tank bottom plate 11 or its outer extension.

[0065] In a like Figure 4 In the specific embodiment shown, the extended planar portion further includes a second welding plate structure 5, which is bevel-welded between the first welding plate structure 4 and the valve body connection portion 22 for sealing and reinforcement.

[0066] In one Figure 4 In the specific embodiment shown, the thickness t3 of the second welding plate structure 5 is greater than the thickness t2 of the first welding plate structure 4 and the wall thickness of the valve body connection or the drain pipe 2.

[0067] In one specific embodiment, the end arc structure of the tank connection part 21 matches the drain port and is welded and sealed to the tank side wall 12.

[0068] In one specific embodiment, the drain valve is a gate valve or a ball valve. Using these two types of drain valves, the bottom of the valve seat is flush with the bottom of the storage tank, preventing pitting and reducing the likelihood of clogging.

[0069] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
